Interview | The "New Force" of Quantum Computing? Magnetic Sigmon can be used as a kind of qubit.

Recently, Christina Psaroudaki, a researcher at California Institute of Technology, and Christos Panagopoulos, a professor at Nanyang Technological University, put forward the idea of using Sigming as qubit, and said that it has advantages in practicality and scalability.

The research paper was published in Physical Review Express on August 4th, local time, titled "Skyrmion qubits: a new class of quantum logic elements based on nanometer magnetization".

"Quantum computing is expected to significantly improve computing power through the inherent characteristics of quantum mechanics, surpassing today’s supercomputers." In an exclusive interview with The Paper (www.thepaper.cn), Psaroudaki said, "Quantum computers are based on qubits, which are represented by the special quantum state of a physical system. Unlike the 0 or 1 of classical bits, quantum bits can also be in the so-called superposition state-that is, both 0 and 1. In order to realize quantum computers, many different candidates are currently being sought. "

The paper shows that the core of quantum computing is qubit made of very small particles such as atoms, ions or electrons. At present, superconducting circuit is one of the leaders of noisy medium-scale quantum computing scheme. Its size is macroscopic, but it has perfect quantum characteristics. Although superconducting quantum has made great progress, there are still great challenges, especially in control and scalability.

In magnetic materials, when the spin orientation of local atoms deviates, a quasi-particle with vortex structure will be produced, which is called magnetic sigmon. The properties of this quasi-particle can generally be described by topological charge or helicity.

"Sigmon has 1/2 spin, so it can be used as a qubit. Because of its good stability, controllability and measurability, it can be used as a logical qubit in quantum computing. The so-called logical qubit refers to the unit that can realize the function of qubit logically and consistently, and the physical deviation and failure probability have little influence. " Zhao Yukang, an industry expert of Guo Dun Quantum, told a reporter from The Paper (www.thepaper.cn).

"Magnetic Sigming can be very small, reaching the nanometer level, and it is a candidate for the next generation of information storage and logic technology. Magnetic Smirnology is a field that deals with the development of classical Smirnon spintronics, and it has developed into a huge and active research field. " Psaroudaki said, "An important feature of our proposal is to accelerate the development of Sigmund quantum bits by using the knowledge and the most advanced technology in the field of Sigmund. The knowledge and technology of Sigmund can be directly used and transferred to our proposed platform, and it provides advantages in practicality and scalability. "

Sigmon qubit

The scheme proposed by Psaroudaki and Panagopoulos is to realize qubits by using stable magnetic sigmons bound in magnetic nano-disks, and to connect different magnetic nano-disks by using electric fields.

By applying the electromagnetic field, the discrete energy levels in the quantized energy spectrum of the magnetic Sigmon can be controlled, so that the helicity between different energy levels can be changed, and these two energy levels can be encoded into two quantum states |0 > and |1 > of the qubit. In addition, the electromagnetic field can be tuned to control the coherence time of qubits. In this design, the quantum bits of adjacent magnetic nano-disks can also be coupled with each other, thus realizing two-bit quantum gate operation. Finally, the reading operation of quantum information can be completed by using a high-sensitivity magnetometer.

A member of the domestic quantum team gave a detailed introduction to the reporter of The Paper (www.thepaper.cn) on how the magnetic sigmoid in this research is used in quantum computation. He said, "This paper uses the quantum computation of the spin angle φ in the XY plane, a quasi-particle of magnetic sigmoid. According to the different parameters, it is divided into two bit theory designs. "

"The first is to encode the qubit state by using the deviation of the spin component in the z direction from the equilibrium state, and the deviation of 0 or 1 represents the 0 or 1 state of the qubit respectively. This design is similar to the charge qubit in superconducting bits, and the bit state is encoded by the number of charges on the island. The second is to encode the qubit state by using the rotation angle of spin in XY plane. The two angles in opposite directions represent the zero state or the one state of the qubit respectively. This design is similar to the magnetic flux bits in superconducting bits, and the quantum bits are encoded by clockwise and counterclockwise currents. " The member said.

Psaroudaki said that because the sigmons can be manipulated by electric and magnetic fields, the quantum bit properties of multiple sigmons are configurable and can be optimized. This includes logical qubit state and qubit lifetime, which are very important to realize stable and reliable qubits and can perform various logical operations. "Our work shows that the Sigmund quantum bit is very attractive as a logical element of quantum processor, and it is coping with the key challenges of quantum bit technology-control and scalability."

The paper shows that scalability, controllability of microwave field, operating time scale and non-volatile readout technology are all together, which makes the Sigmund qubit very attractive as a logic element of quantum processor.

At present, Psaroudaki and Panagopoulos have found several candidate materials, which can be used to design artificially adjustable magnetic Sigmon qubits. They predict that with the development of research, more materials will emerge in the future to realize this kind of magnetic sigmoid qubit.

When talking about the prospects and challenges of Sigmund in the field of quantum computing, Psaroudaki said, "Our work is at the intersection of two unrelated research directions-the quantum bit field and the Sigmund field. The former aims at developing quantum computers, while the latter aims at designing future spintronics devices based on magnetic Sigmund. Our idea has introduced a new direction in the field of Siegel electronics and nano-magnetism, and opened up an undeveloped way for quantum computing. The challenge now is practicality, that is, designing architecture for specific functions. "

"This paper constructs quantum bits on two-dimensional magnetic materials, which is really meaningful in physics and creates a new realization method of quantum computing. However, because this is a relatively theoretical article, the discussion of single-bit self-state, single-bit manipulation, inter-bit coupling and bit state reading still stays at the physical level, not at the actual design level. " The aforementioned members of the domestic quantum computing team said.

Zhao Yukang said, "The work of this paper is to experiment the logic gate manipulation ability of a single sigmoid, which is a new possible route of quantum computing, but there is still a gap from the realization, such as the coupling that has not been extended to multiple sigmoids, and the verification of the deterministic manipulation and long-term retention ability of logical qubits is not sufficient."

Domestic nano-liposomes break through the bottleneck of mass production, and online celebrity drug "courier" has reduced "salary"

  Correspondent Tang Tang Our reporter Zhang Wei

  When people get sick, they often have to hang water to take medicine. However, after the drug enters the human body, it is not smooth sailing to reach the designated position, stay for a longer time, be better absorbed, and avoid being accidentally injured by friendly forces.

  In recent 20 years, more and more new nano-pharmaceutical preparations have flooded into the market, and nano-liposomes with the name of "small steamed buns" in the carrier have emerged as the times require. This kind of vesicle with nanometer particle size formed by lipid bilayer can wrap drugs with great toxic and side effects, poor stability and rapid degradation. By fusing with the cell membrane, the carried drugs are concentrated in the focus, so as to achieve targeted administration, and at the same time, the curative effect can be improved, the toxicity can be reduced, and the stability can be enhanced.

  Recently, Professor Gu Ning of Southeast University led a team to break the technical barriers abroad, overcome the key technologies of nano-lipid materials, built the first domestic and largest production line of lipid nanoparticles in the world, and won the first prize of scientific and technological progress in Jiangsu Province.

  Then, how does this nano-scale "little one" take on the heavy responsibility of "packaging" and "transporting" through-train service? What other unknown uses do nanoliposomes have besides their great potential in drug carriers?

  Known as the secret weapon of "rejuvenation"

  The formation of liposomes is due to the self-assembly properties of a substance called phospholipids. Phospholipid is an amphiphilic substance, one end is hydrophilic and the other is lipophilic. Due to the particularity of its molecular configuration, phospholipid will spontaneously assemble into a bimolecular membrane structure in water, and part of it will be wrapped inside, which is usually called "vesicle".

  The earliest liposomes were naturally formed in water. After scientists discovered its special skills, they tried to synthesize phospholipid compounds by artificial methods in order to achieve the purpose of mass production. The diameter of liposomes is usually tens of nanometers to tens of millimeters, and "nano-liposomes" are liposomes with nanometer particle size.

  The membrane structure of lipid nanomaterials is very close to the cell membrane, which provides convenience for drug delivery and absorption. Therefore, liposomes can wrap the effective components and introduce them into cells, so that the effective components can easily enter cells.

  In many common drugs, liposomes are responsible. Such as antineoplastic drugs, drugs targeting reticuloendothelial system, protein and nucleic acid drugs, antibacterial drugs, anti-inflammatory hormone drugs, etc. Moreover, the drug with liposome as the carrier "skin is not delicate" can be administered in any way, including intravenous injection, subcutaneous and intramuscular injection, oral administration, pulmonary administration and skin administration.

  "The size of liposomes is related to the route of administration and drug release rate, but nano-sized liposomes have obvious advantages as drug carriers." Professor Gu Ning told reporters that daunorubicin liposomes, for example, have a particle size of 60-mdash; 120 nm, because of its small particle size, it is not easily recognized by phagocytes of reticuloendothelial system after entering the blood circulation, so it can stay in the blood circulation for a long time. At the same time, the pharmaceutical preparation has no obvious cardiotoxicity.

  In recent years, more and more nanoliposome drugs have flooded into the international market and become the fastest-growing high-end pharmaceutical preparation in the world. Nanoliposomes not only play an important role in the pharmaceutical industry, but also act as a professional "courier" in cosmetics. It can keep the activity of cosmetics well, so that growth factors and other ingredients can enter the stratum corneum faster and more completely, thus enhancing the cell repair ability. Therefore, liposome encapsulation is known as the secret weapon of "rejuvenation".

  Oil-loving and hydrophilic "amphiphilicity" increases the difficulty of mass production

  In recent years, in the international pharmaceutical field, dexterous and multifunctional nanoliposomes have almost become "online celebrity".

  At present, a total of 29 nanoliposome drugs have been approved for marketing in the world. In addition, there are 87 nanoliposome drugs in clinical research stage and 132 nanoliposome drugs in preclinical research stage. Among them, there are 13 nanoliposome drugs approved for marketing by the US Food and Drug Administration (FDA).

  In sharp contrast, only three nanoliposome drugs in China have been approved for production, namely paclitaxel liposome for injection, doxorubicin hydrochloride liposome and amphotericin B liposome for injection.

  But 10 years ago, the related drugs and cosmetics in China were blank, and the people in China could not touch them at all, because the key technologies of lipid nanomaterials were in the hands of foreigners.

  The international market share of nanoliposome drugs is increasing year by year, but the industrialization development in this field in China has been slow. "The reason is that the lipid nanomaterials needed by nanoliposome drugs are completely imported, and their prices far exceed the raw materials themselves; Second, the quality, purity and stability of domestic liposome pharmaceutical preparations need to be improved; Third, the assembly technology of lipid nano-materials and the preparation technology of lipid nano-drugs have high requirements and great difficulties. " Professor Gu Ning told reporters.

  In 1970s, when liposomes were first used as drug carriers, they were once ignored because of their extremely unstable structure and low drug encapsulation efficiency. With the in-depth study of liposomes, the existing problems have been solved initially. In the early 1990s, economical and efficient anti-fungal and anti-cancer drug liposomes were put into the market, which greatly promoted the research and development of liposomes.

  Lipid nano-materials have unique hydrophilic and lipophilic "amphipathy", which makes it possible to add lipophilic and hydrophilic drugs and active ingredients to the same drug at the same time.

  However, researchers have also found that the amphiphilic nature of lipid nanomaterials is a double-edged sword, which not only provides convenience for drug loading, but also increases the difficulty of mass production. Therefore, the preparation process of lipid nano-materials is complex, which makes it difficult to remove impurities, and it is difficult to purify intermediates and products, so it is difficult to achieve mass production.

  It is also a treasure to use "the wind blows on both sides"

  The raw materials for preparing nanoliposomes are not complicated, but if you can’t master the doorway, you can’t make qualified nanoliposomes.

  Well-made liposomes have a phospholipid bimolecular shell, which is very similar to the structure of cell membrane, and they are very small, and their diameters are basically below 150 nanometers, which is helpful for the penetration of active substances.

  To realize the localization of lipid nanomaterials, the synthesis process is particularly important. Therefore, Professor Gu Ning’s team put forward an innovative new process for synthesis and purification of lipid nanomaterials. Through self-made separation filler and independent separation and purification technology, they realized the industrialization of high-purity lipid nano-medicinal carrier materials.

  Lipid nano-materials are hydrophilic at one end and lipophilic at the other, which seems to be "the wind blows on both sides", so how to use them well is also very particular. After repeated experiments, researchers finally found a "trick up my sleeve". "We creatively put oil-soluble drugs on the oleophilic outer layer and water-soluble drugs on the hydrophilic inner layer, giving full play to the role of drugs, and truly fostering strengths and avoiding weaknesses." Professor Gu Ning said.

  According to Professor Gu Ning, they developed a new process for the synthesis and purification of lipid nanomaterials, which used a "one-pot" reaction to prepare key intermediates, and the yield was doubled. At the same time, the liposome coordination technology broke through the key bottleneck of the assembly of glycyrrhizic acid drug phospholipid complex. Diammonium glycyrrhizinate was complexed with phosphatidylcholine, a lipid material, to form a lipid complex, which greatly improved the lipophilicity of glycyrrhizic acid and made it easier to cross the multiple membrane structures of the digestive tract and enter the blood circulation, effectively solving the problem of low oral bioavailability of glycyrrhizic acid.

  After the success of the project, the price of domestic lipid nano-materials dropped significantly, which significantly reduced the overall cost of liposome drugs. In addition, lipid nanoparticles technology has been widely used in domestic first-line cosmetics companies, and it has played a great role in preparing cosmetics with whitening, anti-aging and wrinkle removal functions.

The localization is less than 5% … Is this consumable also welcome to "cut the price at half price"?

On December 9th, Shaanxi Provincial Public Resources Trading Center issued the "Publicity on the results of the proposed selection of pacemakers in the centralized procurement of pacemakers in provincial alliances (regions and corps)" (hereinafter referred to as "Publicity").

Review of pacemaker collection

Previously, several inter-provincial alliances have carried out the collection of pacemakers.

In 2019, Jiangsu Province launched the first domestic collection of pacemakers. The average price of this collection decreased by 15.86%, with the highest decrease of 38.18%. Among them, four of the five companies selected were imported, namely Medtronic, Abbott, Baiduoli and Boke, and only one domestic company was selected.

Since then, many provinces have also carried out the collection of pacemakers.

Up to now, the centralized purchase of pacemakers has covered three provinces (cities, districts) in 27 provinces, including Anhui, Jiangsu (two rounds have been carried out), Qinghai, Shandong, Fujian, Zhejiang (under planning), Qujing, Yunnan, Beijing-Tianjin-Hebei "3+N" and Shaanxi seven provinces and one corps, and only Shanghai, Hubei, Shanxi and Guangdong have no arrangements.

Judging from the existing collection results, the highest decline was the second round of cardiac pacemaker collection in Jiangsu Province in May this year, with a decrease of 69%. Although the Shaanxi Alliance has not announced the result of the decline, the average decline of the products to be selected is 57.77% and the highest decline is 78.26% based on the average price of 50,000-60,000 in the past.

Compared with coronary stents and artificial joints, the price reduction of cardiac pacemakers is very mild. This is not unrelated to the current market structure of pacemakers in China.

The domestic production rate is less than 5%, and it is too early to cut prices drastically.

At present, Medtronic, Abbott and Bocco account for 43.0%, 23.7% and 17.8% of the domestic pacemaker market respectively, and the three giants together account for 84.5% of the domestic market. Together with the second echelon’s Baiduoli and Sorin Group, the market share of imported pacemakers in China reaches 95.7%.

In recent years, the annual implantation of pacemakers has been increasing year after year, and the growth rate is maintained at around 10%. It is expected that about 100,000 pacemakers will be implanted in 2020, and the market scale will reach 4 billion yuan.

With the increasing demand in the market, a few imported enterprises occupy the vast majority of the market share. On the whole, China’s pacemaker market still belongs to the "seller’s market", and it is not realistic to achieve a substantial price reduction.

Looking back at the field of domestic pacemakers, the technology of local enterprises in China is still in the initial stage. If the price of centralized purchasing is too low, the market price of products will be reduced below the research and development cost. If there is no desirable benefit, who else is willing to face the difficulties and conduct independent research and development?

Moreover, unlike other conventional consumables, manual follow-up and maintenance services after implantation account for a large proportion in the cost of pacemakers. Pacemakers will be carried for life after being implanted in human body. Follow-up doctors need to put a special small computer probe on the skin and remotely check whether the pacing system works normally in vitro.

At present, China has not been able to establish a follow-up service technical team. If foreign-funded enterprises lose the election because of their varieties and their profits drop too much, they will change the existing service model and cut off the labor service costs such as follow-up, which will have a huge impact on patients. Based on the above considerations, the bargaining range of centralized mining needs to be more cautious.

Heyihui medical treatment viewpoint

Centralized purchasing is a "double-edged sword". How to use the "price-cutting knife" of the policy to realize the double benefits of price control and industry development is a difficult problem..

Since the beginning of centralized procurement, the fields of artificial joints and coronary stents have experienced an ultra-high decline of up to 80% and 90%, which once made the industry discouraged. At the same time, in the medical field where patients’ health is paramount, the chronic diseases in the bidding field such as "winning the bid at the lowest price" and "bad money driving out good money" are criticized by the industry.

No matter how centralized purchasing develops, its ultimate beneficiary should be the patients. Based on the characteristics of the medical industry, how to grasp the bargaining degree of centralized purchasing really tests the decision-makers’ understanding of the industry and also affects thousands of medical device enterprises.

Experience a special education teacher’s day and lift the wings of a broken-winged angel together.

  Shi Yang (right) uses toys to attract the attention of hearing-impaired children.

  Liu Fang teaches students in sign language.

  Zhang Yi gives instructions to the students.

  Xia Hao’s students are studying in the classroom.

  In the special education industry, students are generally called "angels with broken wings" because of physical defects. These children can’t hear the sound of the world or see the colors of blue sky and white clouds. Fortunately, there is such a group of people who have knocked on the hearts of children with love and persistence year after year. They may rarely feel the sense of accomplishment of "peaches and plums are all over the world", and what makes them happy is nothing more than the students making their first sound, knowing a new word and mastering a life skill … … They have a common name: special education teacher.

  On the eve of Teacher’s Day, the reporter of Xi ‘an Evening News invited some citizens’ representatives to enter the world of special education teachers in primary schools, middle schools, universities and other places, and experience the "one day of special education teachers", showing the original ecology of special education teachers’ work and life, and experiencing their different teaching and unknown ups and downs.

  Shi Yang, a language training teacher for children’s rehabilitation — —

  A guide for hearing-impaired children at the beginning of their lives

  "Where are the little cat’s eyes? Xuan’s eyes blink. " On the morning of September 6, in the classroom of the Rehabilitation Training Center of the Second School for the Deaf in Xi ‘an, Shi Yang, a rehabilitation language training teacher, was giving a parent-child class to the hearing-impaired child Xuan (a pseudonym) and Xuan’s mother. Xuan Xuan, 1 year and 7 months old, is a little angel whose ears are covered by God. She was screened for hearing impairment at birth and was diagnosed deaf six months later.

  Shi Yang played a game with a kitten toy to attract her attention. There are also many toys and audio, triangle iron, drums and other vocal AIDS covered with cloth around her. Shi Yang said that normal children can hear voices when their mothers are pregnant, and hearing-impaired children have adapted to the silent world when they are diagnosed again at birth. Even if you wear hearing AIDS, you should start training as soon as possible, so that children can hear and perceive sounds and their corresponding things, and finally learn to make sounds.

  "Rehabilitation training is the enlightenment point of hearing-impaired children, the first step to create possibilities and hopes for them, and an extremely important step. If the effect is good, hearing-impaired children can speak normally." Shi Yang said that more and more parents are aware of this and take their hearing-impaired children to language training as soon as possible. The youngest student in the rehabilitation training center this year is only one year and one month.

  Because the students are young and can’t sit in the classroom and concentrate on training, Shi Yang can only attract his attention with toys. In class, when she cried, she sang children’s songs, and she made a lot of noise. She had to stop the class and play with her. Sometimes she would climb everywhere, and Shi Yang would climb all over the classroom.

  "Try not to let the child see the mouth shape, let her listen to the voice more, the child has strong imitation ability, and can’t talk frequently." After training Xuan’s listening comprehension, Shi Yang will also give guidance to Xuan’s mother and demonstrate that Xuan’s mother can also train her children correctly at home.

  Unlike other teachers in class, the students are young, and Shi Yang needs to sit cross-legged on the mat for class. After a class, her legs are all red, and when she stands up, she almost loses her footing. Just after seeing Xuan off, another pair of parents and children who had a parent-child class walked into the classroom again.

  "I never feel tired. I have seen too many children open their mouths for the first time ‘ Mom ’ The scene has also seen many children successfully get out of school after recovery, which is the best reward for me. " Shi Yang said that she has always had a dream that all deaf-mute children can enter ordinary schools. Only deaf-mute children without deaf-mutes is her never-ending goal.

  Citizen representative experience

  "The first time I saw a class for such a small deaf-mute child, it was not easy for Teacher Shi to climb over and interact with the students." After a rehabilitation language training class, Li Hao, a citizen representative, was deeply touched. In his view, scientific correction and early intervention are important missions of special education, and special education teachers play an irreplaceable role in these two aspects.

  "Teachers use professionalism and patience to care for special children and help them integrate into society. The special education teacher represented by Shi Yang is the guider of special children in the early life, and interprets the significance of rehabilitation education with professional spirit. "

  Liu Fang, a Chinese teacher in a deaf-mute school — —

  Help children build logical relationships word by word.

  "This year’s lilacs seem to be particularly lush, both inside and outside the city … …” As soon as I entered the teaching building of the Second School for the Deaf in Xi ‘an, I heard the sound of reading with unclear words, which was completely different from the imagined silent classroom.

  These reading sounds were read by nine deaf-mute students in grade seven, who used sixth-grade textbooks from ordinary schools. Liu Fang, a Chinese teacher, stood on the podium and led the students to read aloud together. In order to let the students see the mouth shape of pronunciation clearly, she tried to read every word fully, even exaggerating, and commanded up and down with one hand following the tone.

  Liu Fang took the students to read the passage of nearly 100 words for three times, and asked two children to go on stage to sketch sentences describing lilacs. After the whole class, only two paragraphs of the six natural paragraphs were spoken. Liu Fang said: "I have taught them the words in the text in one class the day before. It takes at least four or five classes to finish a text."

  Liu Fang said that because of the lack of language environment, deaf-mute children are prone to problems of disordered word order and unreasonable logic, and their language use ability is very poor. Writing articles is just keeping a running account. In order to help students establish logical relations, straighten out word order and make better use of words, she can only lead students to read and help them understand again and again, so as to achieve the point where practice makes perfect.

  There is a timetable on the back wall of the classroom, in which Chinese and math classes account for most, and most of them are connected with two identical courses. Liu Fang said that one class can only talk for a short period, and only two consecutive classes can finish one class. "The Chinese class in the compulsory section is an important step to help deaf children establish a logical relationship, and they dare not relax."

  Exaggerated oral expression and standard sign language movements, in order to attract students’ attention, she kept walking in the classroom. After two classes, Liu Fang’s voice was a little hoarse. She put her hand on the podium and said "goodbye" to the students with a smile.

  Liu Fang said with a smile that these special children are as keen as radar. Once, they were in a bad mood. Although they tried their best to hide their emotions, they were discovered by the children. "Teacher, are you in a bad mood? Don’t feel bad. " Liu Fang, who was in class, was interrupted by students. A simple and unclear sentence made her surprised and moved. Since then, her face has been full of smiles every day in class. "No matter how tired I am, I can’t show it. I hope I am a person with light in my heart, illuminating the children’s world with my own light and making them feel warm."

  In her seven years as a teacher, Liu Fang received flowers from students for the first time the year before last. "I clearly remember that it was a red carnation wrapped in white plastic paper with purple dots on it." Liu Fang’s eyes are a little wet. She said that if she can make a wish, she hopes that the children can make a little progress every day, and with the help of teachers and parents, they can master life skills and live independently when they leave campus. This is her most anticipated Teacher’s Day gift.

  Citizen representative experience

  "The Chinese class for deaf-mute children is like this. The teacher is too hard." Mr. Zhong, a college teacher who lives in Furong West Road, was very emotional after experiencing a Chinese class for special children. "Teachers should not only tell the children the content of the course loudly, but also do sign language at the same time, so that the children can understand the content of the article from two aspects: sound and movement."

  Zhong Yibo said: "When Mr. Liu Fang speaks every word, she will guide the children to pronounce a tone close to the correct pronunciation through the combination of pronunciation skills and sign language, which is not easy compared with giving lessons to ordinary children."

  Zhang Yi and Wang Shuai, football coaches of blind and dumb schools — —

  One-armed teachers form blind football teams.

  "Wu Jiacheng, stop first, the left shoelace is open." On the afternoon of September 6th, the newly formed football team of Xi ‘an School for the Blind and Dumb gathered on the playground. Coach Wang Shuai saw a student’s shoelaces open and squatted on the ground to help him tie them. Another coach, Zhang Yi, stood in the front row, followed by other students, hand in hand, standing in front of the goal about 80 meters away.

  Wang Shuai guarded the goal, shouted "Go", and threw a football with bells inside, which could make a sound. A student opposite waved his arm and moved in the direction of the sound. The little football hovered between the students’ left and right feet and moved in the direction of the goal. Just a few steps later, the football was "lost", and the students looked half-faced, followed the sound of the bell, and then went to get the ball back.

  This is a special team. The players are a group of blind children. Wang Shuai, who was guarding the goal, kept shouting "Hey, hey, hey" while clapping to guide the students. The student got up the courage to kick and the ball scored, but the child who didn’t know the shooting situation still stood where he started. "The goal is great. Go back to the queue." Only after Wang Shuai gave the student an affirmation did the student happily run back to the queue.

  "Pay attention to pressing down the center of gravity and swing your arms naturally." Zhang Yi, the coach of the team leader across the goal, has been observing the movements of each student and then correcting them one by one. Zhang Yi has been a coach at school for 22 years. Before he came to school, he lost his left arm in an accident. As a computer teacher, he happened to see students kicking plastic bottles and asked them what they were doing. The student replied that he was playing football, which made him feel the students’ desire for sports, so he formed a football team. The newly formed team, with a total of 13 people, has just started the training of basic movements. Every movement should be demonstrated to let the children feel and learn, and then bend down to straighten their movements one by one. A team needs to train for at least one and a half years to make all the players run with the ball without dropping it. To reach the level of completing the game, it needs to train for at least three years.

  Wang Shuai has been a coach for 19 years. When it comes to the preliminaries, he and Zhang Yi practice with their students for more than ten hours every day. Referring to these years of training, Wang Shuai said frankly: "Tiredness is certain, but we have the motivation to persist." Today, Li Yu, a professional athlete of Liaoning province’s football team for the blind, used to be a student of a school for the blind and dumb.

  Zhang Yi believes that blind feet can not only help children get rid of blindness, but also enhance their physical fitness and improve their self-confidence and ability to live. "The world running in the sun is bright, and it is our greatest comfort to see their progress."

  Citizen representative experience

  "I can’t walk with my blindfold on, let alone play football. Blind students play too well. " After watching the training organized by Zhang Yi and Wang Shuai, Bai Yang, a citizen representative, expressed his deep respect for the two teachers. Bai Yang said that it was touching that Mr. Wang Shuai carefully examined the details of each child’s shoelaces before the training began. Teacher Zhang Yi has only one arm, and can also guide and lead blind students to run and play football on the playground. "We can’t imagine teaching blind students to play football, but the two teachers really did it." — — Bai Yang (employee of a bank in Keji Road, High-tech Zone)

  Xia Hao, the head teacher of senior three in the school for the blind and dumb — —

  Guide students to "touch" the beauty of mathematics

  Xia Hao used to be a coach of the football team of Xi ‘an School for the Blind and Dumb, but since he taught senior high school students, he temporarily put aside the work of the football team and devoted himself to preparing for the college entrance examination.

  "The college entrance examination is an important threshold for children, and I hope to help them seize this opportunity to enter colleges and universities." Xia Hao said that there are only three students in his class, and he is a senior three this year, which is also the first senior three since the establishment of the school for the blind and dumb. The first session means zero starting point and zero reference, which requires Xia Hao to pay more efforts and care.

  The first thing Xia Hao does when he comes to school every day is to go to the classroom first. He cleaned the classroom and checked it again for obstacles to ensure that all the students arrived at school safely.

  All three students in the class like music and have formed a band, dreaming of being admitted to Changchun University for further study. Students rehearse twice a week for two hours each time. Xia Hao is the logistics and chef of the band. He always accompanies students, helps to set musical instruments and move chairs. When the band went out to perform and compete, it was Xia Hao’s job to move the stereo and musical instruments. He ran before and after by himself, and took over all the work.

  Mathematics is one of the most difficult subjects for blind students. As a math teacher, Xia Hao should also guide students to "touch" the beauty of mathematics. Xia Hao said that band training usually takes a lot of time, and he is worried that he will make time for students to make up lessons every night. In order to let students understand mathematical concepts intuitively, he tried many ways of "touch teaching". "Using rice and sand can make them feel the change of volume. To understand the concept of function, I will draw graphics on the palm or back of each child."

  Xia Hao said that the learning status of the three children is different. In order to let the students learn math well, he made a detailed learning record for each child, and he recorded which child was wrong and which piece of knowledge was weak. In class, if a student can’t understand it once, he will teach it three or five times, and repeat it again and again until the student understands it.

  Citizen representative experience

  "Teacher Xia is a class teacher and a parent. I am very touched to hear that he has to accompany students every weekend and holiday, taking them to eat hot pot and jiaozi." Feng Ruili, a community resident who lives in Changyanbao Street, said that next year, Mr. Xia will take his students to their favorite universities to take the college entrance examination, hoping that their dreams will come true. "Although the process is very bitter, Teacher Xia’s efforts will not be in vain."

  Liang Zenghua, Teacher of Special Education College of Xi ‘an Academy of Fine Arts — —

  Innovating traditional courses to stimulate students’ unique talents

  Liang Zenghua is an arts and crafts teacher in the Special Education College of Xi ‘an Academy of Fine Arts. Because deaf people and ordinary people have different understandings of words and sentences, Liang Zenghua often uses pictures to replace traditional characters for teaching. Presentation (PPT) is an essential tool for Liang Ceng Hua’s class. The PPT of a class should be supported by at least two or three hundred pictures. From collecting pictures to making PPT, it takes six or seven hours to prepare lessons for each class, but Liang Ceng Hua never feels hard. He said, "Special children have a more delicate understanding of pictures and have different understandings of art. Picture teaching can better stimulate students’ creativity."

  In addition to being a professional teacher, Liang Zenghua is also the vice president of the College of Special Education, in charge of teaching arrangements. In his view, every special student has a unique talent that is different from and higher than ordinary people, and the traditional arts and crafts as the teaching basis can only ensure the students’ completion of their studies and their basic survival after graduation. In order to expand the unique space belonging to special students, he looked through a lot of materials and visited many colleges and universities. After continuous research, he sorted out a set of innovative and integrated courses.

  "Only by integrating two or three courses and applying arts and crafts to practical arts can students’ works better adapt to the trend of the times and the market." Liang Zenghua, for example, said that by combining the traditional fiber art class with leather goods class, students can be taught to make fiber-woven purses.

  "The duty of university teachers is not only to help students master certain skills and solve employment problems, but more importantly, to help them find their future direction and gain a foothold in society." In Liang Ceng Hua’s view, special students have unique advantages, and deaf-mute students can calm down and create wonderful audio works in a silent world. "College education can make children go further on the road of art, which is also my duty."

  Reporter’s sentiment

  Before the interview, I always thought that specialized courses were to help special students acquire skills, but Mr. Liang Zenghua’s goal was more than that. He always stressed that every special child has absolute advantages, so that special children should walk in front of the social road and stimulate the potential of their unique space. Let students not only have works, but also have creations to keep up with the times. This is the significance of higher education. (Reporter Ma Xiang)

"Retirement" of the First Batch of New Energy Vehicle Batteries: Facing Three Challenges

  With the dual drive of policy and market, China’s new energy vehicle market has experienced explosive growth in the past 10 years. However, it should not be ignored that the first batch of power batteries for new energy vehicles are aging, and a "retirement tide" of power batteries is coming.

  According to the quality assurance ability of 20% battery decay in 8 years of general vehicle manufacturers, China has ushered in a rapid increase in the number of retired power batteries for new energy vehicles since 2017. It is estimated that the number of retired batteries will reach 9.3 billion watt-hours in 2025, and the number of retired batteries will increase by more than 1 million orders of magnitude every year. This will bring huge potential market value of ladder utilization. If the retired batteries are recycled according to the method of first step and then regeneration, it is estimated that the total market size will reach 37.9 billion yuan by 2025.

  As we all know, batteries contain a variety of heavy metal elements, which will cause environmental harm if not handled properly. What will happen when the waste power battery has a huge potential market scale and meets the recycling market system that needs to be improved? What are the "blocking points" that need to be opened?

  1. Value and risk of a "retired" power battery

  According to the national standard of new energy vehicles, power batteries can often be "retired" with more than 80% remaining. This makes the power battery still have great use value after it is retired from the vehicle, which not only forms a huge potential market, but also means certain environmental risks.

  "Generally speaking, after the service life of power batteries is 5-8 years, we encourage ‘ Retired ’ Step use of battery. Although the battery’s cruising range is reduced, it can’t meet the needs of vehicles, but it can be recycled for other energy storage needs, and it can still continue ‘ Service ’ For a while, you can also choose the recycling of batteries in the future. " Jia Jingchun, an associate professor at the School of Chemistry and Environmental Sciences of Inner Mongolia Normal University, introduced.

  Liu Wanmin, an associate professor at material chemistry of Hunan Institute of Technology, told the reporter: "‘ Retired ’ Power batteries can be widely used in power system energy storage, backup power supply for communication base stations, low-speed electric vehicles and small distributed household energy storage, wind and solar complementary, electric forklifts and other fields. Generally, it can be used to about 60% of the initial capacity of the battery. According to different usage scenarios, the service life can range from several months to several years. "

  It still has the use value of several years, which makes "step by step utilization first, then recycling" become the first choice for recycling "retired" power batteries. Cascade utilization refers to the application of "retired" power batteries in other fields. Recycling is to disassemble, crush and screen the "retired" battery, and extract lithium, cobalt, nickel and other metal elements from the battery by leaching hydrometallurgy or pyrometallurgy, and use them in the production of secondary batteries.

  The reporter learned that power batteries contain metal elements such as lithium, cobalt, manganese and nickel, and the cost of raw materials accounts for 50%~70% of the total cost. The lithium salt and cobalt salt consumed by power batteries have become the largest proportion in all application fields of lithium and cobalt. With the rapid consumption of primary resources, the recovery of secondary resources should reach the corresponding level. Since the release of National Mineral Resources Planning (2016-2020), China has reserved rare earth metal minerals as strategic resources. Therefore, recycling metal elements in power batteries can not only better develop circular economy, but also effectively alleviate China’s long-term dependence on such resources.

  However, Jia Jingchun also pointed out that lithium batteries contain heavy metals such as lithium, and some batteries use organic electrolytes and organic separators. Different from the simple recycling method of traditional lead-acid batteries, the metal recycling process of lithium-ion batteries is relatively complicated. Once improperly operated, these heavy metals and organic electrolytes will bring serious threats to the environment.

  "After the battery is dismantled, we generally use hydrometallurgy or pyrometallurgy to recycle lithium, nickel, cobalt and other metal elements. Improper disassembly will lead to many problems such as safety, environment and resources. From the safety point of view, there are hidden dangers such as electric shock, short-circuit explosion and hydrofluoric acid corrosion. From the environmental point of view, there are heavy metal pollution such as cobalt and nickel, fluorine pollution and white pollution caused by battery diaphragm. From the perspective of resources, there is a waste of high-priced resources such as lithium, nickel and cobalt. " Liu Wanmin said.

  2. Battery recycling enterprises face three major challenges.

  Although the recycling potential is huge, at present, there is no leading enterprise in the power battery recycling market, and even some chaos has occurred. Earlier, some media reported that many host manufacturers have established battery recycling business. However, some power batteries did not flow into the formal channels, but were bought at high prices by unqualified and highly polluting small factories and improperly treated, causing hidden dangers of secondary environmental pollution. Why is this so?

  "First, at present, users of new energy vehicles are not strong enough to recycle power batteries; Second, the recycling price of some small workshops is much higher than that of regular recycling enterprises; Third, the enterprises that recycle batteries have high qualification requirements, which leads to a limited number of formal recycling enterprises; Fourth, the recycling technology is immature and the recycling business model lacks innovation. " Liu Wanmin analyzed.

  Among them, the ladder utilization and recycling is the most difficult. Although China has become the country with the best development of new energy vehicles in the world, power battery is still a new technology. In the eyes of the industry, enterprises still face three major challenges in battery recycling: inconvenient battery disassembly, unknown residual value of battery health and low economic benefits.

  The complexity of "retired" batteries is high. Different power batteries have different internal and external structural designs, module connection methods and process technologies, and only have square, cylindrical, soft bag and other shapes. This directly led to the later disassembly work can not be large-scale operation, which increased the difficulty of disassembly and labor costs. If the operation is improper, it is more likely that short circuit will cause fire or explosion, leakage will pollute the surrounding environment and threaten the health of employees, resulting in casualties and property losses.

  At present, there is no data record of the usage of some "retired" power batteries, only the original data when they leave the factory, and the usage process and current state are unknown. Before the power battery is used step by step, each module must be tested, which greatly increases the cost of the enterprise. At the same time, based on the limited data, the prediction of the remaining life is not accurate enough, which will undoubtedly increase the quality risk of the products.

  The above factors make the economic benefit of recycling power batteries low. A staff member of a battery recycling enterprise told the reporter that the small workshop gave up many key links such as detection and discharge in battery recycling, and the operators did not receive professional training, so the operating cost was much lower than that of regular enterprises, thus having more room for bargaining power and battery acquisition cost, which caused vicious competition with regular enterprises.

  3. The maintenance traceability of the "ID card" of the power battery has not been smooth.

  In fact, as early as 2016, China has issued the "Implementation Plan for Extended Producer Responsibility System", requiring the establishment of a recycling system for electric vehicle power batteries. The plan points out that electric vehicle and power battery manufacturers should be responsible for establishing a waste battery recycling network, recycling waste batteries through after-sales service network, and publishing recycling information to ensure standardized recycling and safe disposal of waste batteries. Power battery manufacturers should implement product coding and establish a full life cycle traceability system.

  On July 31, 2018, the national monitoring platform for new energy vehicles and the comprehensive management platform for the traceability of power batteries (hereinafter referred to as "the national traceability management platform") was launched. The platform was built by the National Engineering Laboratory for Electric Vehicles of Beijing Institute of Technology, and its main function was to collect information and monitor the whole process of power batteries’ production, sales, use, scrapping, recycling and utilization, so as to realize that the source of power batteries can be traced, the destination can be traced and the nodes can be controlled.

  At present, the national traceability platform has collected more than 5.6 million vehicle information data, including new energy passenger cars, buses, special vehicles, etc., and the total number of supporting batteries exceeds 8.9 million, with batteries exceeding 28 billion watt-hours. It involves more than 290 new energy vehicle manufacturers and more than 180 battery companies.

  The establishment of the whole life cycle traceability system means that every car’s battery has its own "ID card". But why do batteries still flow into small workshops? Some insiders pointed out that although China has established a traceability management system, due to the lack of mandatory policies, enterprises have problems such as serious lag, incompleteness and difficulty in traceability when reporting data. At the same time, the current policies and regulations are not binding on how car owners deal with batteries, which also gives small workshops an opportunity to buy power batteries.

  "In 2015, China’s technical policy has clearly stated that a power battery coding system will be established. The Interim Measures for the Management of Recycling in 2018 proposed the establishment of a power battery traceability information management system, coding technical standards and related information sharing mechanisms. However, in reality, there are many types and quantities of enterprises involved, such as battery manufacturers, battery maintenance and replacement institutions, battery leasing enterprises, and cascade utilization enterprises. The battery life cycle is as long as several years, and coding maintenance is difficult. " Liu Wanmin said.

  Jia Jingchun said: "Professional battery recycling is a large-scale system engineering. How to recycle requires coordination from all sides, especially the cooperation of automobile manufacturers, battery manufacturers and related extension industries. Once a link in the whole cycle is unreasonable, it will inevitably lead to problems of lag and other derivatives in recycling. "

  4. The national standard system for battery recycling still needs to be improved.

  By the end of 2020, China’s National Standardization Administration Committee has issued five national standards for the recycling of vehicle batteries, basically forming a standard system framework. In addition, the regulatory policies for the recycling of power batteries, the relevant standards of the echelon industry and the industry regulatory system are also being improved. However, some insiders pointed out that most of the standards currently issued are recommended standards, and there are problems such as insufficient binding force and lack of superior law in the implementation process.

  "At present, new energy owners are interested in ‘ Retired ’ In fact, most people are still vague about how to dispose of batteries. Some car companies have introduced battery replacement, such as full mileage or ‘ Service ’ Time for battery replacement and recycling. However, the large-area battery life of new energy vehicles has not yet arrived. " Jia Jingchun said that he pointed out that over time, new energy owners will gradually become more experienced in how to properly handle power batteries. "At present, we should establish corresponding supervision and legislation to ensure that used batteries can be returned to manufacturers or recycling enterprises. At the same time, the supervision of battery production and use must be formed. After leaving the factory, traceability, use tracking and battery destination after use all need a set of supervision mechanisms. "

  Many experts in the industry pointed out that in order to speed up the recycling of power batteries, in addition to strengthening the implementation of the producer extension system, there are still three aspects to be improved in the future: first, we must strengthen publicity and raise consumers’ awareness of environmental protection; Second, we should formulate policies to subsidize or reward enterprises that actively participate in battery recycling, and at the same time crack down on non-compliant recycling; The third is to speed up the transformation of intelligent equipment in enterprises, improve the efficiency of battery recycling, reduce the recycling cost through economies of scale, improve the bargaining power of enterprises, and provide effective protection for the normal operation of enterprises, thus fundamentally solving the industrial problems of high cost and low profit and guiding the further standardization of battery recycling.

  As many batteries go online, there are many batteries to be "retired". As an important part of the development of new energy vehicle industry in the future, the healthy and standardized development of power batteries is very important.

  This year’s government work report mentioned that the construction of power battery recycling system will be accelerated. At the national level, China has accelerated the legislative process of power battery recycling. In addition, the reporter learned that on March 29, 2021, the national evaluation and trading platform for "retired" power batteries of new energy vehicles (also known as battery house) was established in Foshan City, Guangdong Province.

  The platform will aggregate the resources of the National Engineering Laboratory for Electric Vehicles, the National Monitoring and Management Platform for Battery Traceability and the specialized committee for recycling new energy batteries, and strive to maximize the battery utilization rate. Based on the blockchain technology, it will provide many services for new energy automobile enterprises, such as performance evaluation of big data power batteries, offline laboratory testing and online trading of power batteries, and it is also expected to help solve the industrial problems such as difficult recycling, limited sales channels and lack of rapid performance testing technology in the recycling of power batteries.

Have you ever eaten the pineapple that grew up in the sea?

Watch the pineapple grow up in the sea.
This is HainanDuoge villageA pineapple field ↓
Unlike other places, this fielddepend onLanding on the seaThe pineapples in the field grew up watching the sea. What’s the smell of pineapple growing up in the sea?

00:54
Our reporter Gong Baichao tasted it for everyone.Sweet with a little saltIt tastes a little fresh. Eating this pineapple, it is estimated that you can avoid the step of soaking in salt water.
Everyone knows that Hainan Island is "Tropical waterfruitParadiseDuoge Village, located in the eastern part of Hainan Island, is also fragrant with fruits all year round, with coconut, banana, longan and other fruits dazzling.
Among the fruits rich in Duoge Village, the most famous one is the number.pineapple.
Almost every family here grows pineapples, and the planting area isMore than 10,000 muThe output value created is as high asMore than 30 million yuanThe per capita annual income of villagers is close.20,000 yuan.
By planting pineapples, the villagers lived in two or three-story buildings and drove private cars. The money for children to go to school was also earned by planting pineapples.
Qiaoxiang Duoge
Duoge village is a village withMore than 300 years of historyThe village.
In the early years of Qing Dynasty, the Tseng brothers and their clansmen migrated from Fujian coast to Shanqin Bay in Hainan, and gradually formed villages. At that time, people still used offshoreFishing for a living.
In order to make their families live a better life, many villagers began toAway from home, across oceans.Go to Singapore, Malaysia and other places to work hard. Duoge Village has thus become a famous place in Wanning.village or town inhabited by relatives of overseas Chinese and returned overseas Chinese.
Pineapple opens the way to wealth.
The pineapple cultivation in Duoge Village is fromMore than 30 years agoIt started.
In the late 1980s, when villager Zeng Xianruo went to Wenchang to sell seafood, he found that there were many stalls selling pineapples.
At that time, pineapples were relatively rare in Hainan, so out of curiosity, he asked how much they cost.80 cents a cattyThe price really surprised him.
At that time, the hairtail he sold was only 45 cents, and the price of this pineapple almost caught up with that of hairtail.double;twofoldYes.
Zeng Xianruo thinks that this is achance.
At that time, there were few places to grow pineapples, and their villageClimatic conditions, soil environmentSimilar to Wenchang, if pineapples can be planted, the future development will bevery promising.
After returning to the village, he immediately discussed it with the big guy.
But at that time, most of the fields in the village were planted with crops such as pepper and rubber. If you want to plant pineapples, you can onlyCut down the pepper tree. And at that time, pepperHarvest periodIt’s almost there. It’s a pity to cut it down.
Is it to keep the pepper tree steady, orGet ahead of most peoplePineapple was planted, and finally Duoge village people chose the latter.
People cut down pepper trees, reclaimed more than 100 acres of land, and planted Duoge Village.The first batch of pineapple seedlings.
Many people in the village still remember that year, before the harvest season arrived, the consignee came to buy it. At that time, the output value of pineapple per mu was about 2000 yuan, and 100 mu of land was20More than ten thousand yuanThe income is almost pepper.Two or three times..
hang onThink about change and seek innovation.The idea that the pineapple planting area in Duoge Village is getting bigger and bigger, and the villagers made money by planting pineapples. By the early 1990s, there were many pineapples in the village.wealthy family",and Duoge Village has become famous"pineapple village”。
Thinking about change and seeking innovation can be long-term
However, in the next twenty years, Duoge Village was oncego no further.invariableThe planting mode has made the pineapple industry in Duoge Village graduallyLose an advantage.
In 2017, Duoge Village suffered an unprecedentedselling crisis.
That year, due to the abnormal climate, the ripening time of pineapples was advanced, and many pineapples were produced and Guangdong pineapples were produced.Simultaneous listingAt that time, fresh fruits piled up and the marketoversupply.
At that time, there were yellow pineapples all over the mountains.Unmanned harvesting. The villagers were in a hurry, but there was nothing they could do.
Fortunately, at that time, the Wanning Municipal Government issued the relevant emergency subsidy scheme, and gave transportation subsidies to the distributors who came to Wanning to buy pineapples, which reduced the losses of fruit farmers.
After the crisis, the villagers realized their own shortcomings. In order to broaden their horizons and ideas, they went out of the village and visited various places.
After some discussion, they decided to take advantage of Hainan’s climatic advantages and plant.Off-season pineapple.
To this end, they invited.Expert guidanceAfter more than a year of careful management, the first batch of out-of-season pineapples matured in August 2020, and once the fresh fruit was launched, it wassold out.
Scientific planting and high-quality development
With the development of Duoge Village getting better and better, many young people also choose to return to their hometowns to start businesses after graduating from college. Li Ruchao is one of them.
At first, Li Ruchao sold tropical fruits in his hometown through e-commerce platform. In the process of sales, he found thatBoutique fruitIt has gradually become a market consumption trend.
So he was born.Do fine agriculture and science and technology agriculture.The idea.
In 2020, with the support of the local government, Li Ruchao built a pineapple base in Duoge Village.Modern digital farm.
Through the data collected by sensors in digital farms, you canGuide field management. When to fertilize and when to water, there are more scientific operating standards.
From relying on the weather to relying on the development of science and technology, Duoge village people are constantly seeking innovation and change, and the small village is moving towards a happier future.
At 20:00 tonight, walk into Duoge Village in Hainan and realize pineapple freedom!

There are many writing routines for primary school students: 8-year-olds write "In my life" at the beginning.

  Open column language

  Today, the "Jingmiao Teenager" edition met the readers for the first time at the weekend. In this page, which aims to "let children learn and practice writing", you will see the exercises, comments by famous teachers and activity previews of small reporters in Chengdu Business Daily. In addition to the layout, there will be a wealth of interviews and practical activities for small reporters every week. We will aggregate resources from all walks of life and build a platform for small reporters to recognize and contact the society.

  Let’s provide more ways and means for children to perceive this city and this society.

  Writing a good composition is difficult.

  I’m afraid everyone has an unforgettable experience in composition when they are studying. Whether the words and sentences are quoted, whether the layout of the article is sublimated step by step … … Over time, the composition seems to have a routine.

  However, for primary school students, it is not good to have a routine taste when they first learn to write a composition. Let’s take a look at some examples of primary school students’ composition "routines" told by our Chinese teachers.

  An 8-year-old child begins by writing "In my life"

  Some children in Grade One and Grade Two read a lot of composition books, which not only increased their knowledge, but also learned the prologue of routines and the use of "high-frequency vocabulary".

  Teacher Meng of Shuanglin Primary School has a deep understanding. No matter what composition, the beginning of having a child is always like this: "In my life, I have encountered many things, as many as stars … …” "In my life, I have thought of many people, as many as pearls … …” "In my life, I have experienced many hardships, as many as stones … …”

  "Son, your life has just begun, where did you get so many experiences and insights?" Every time I meet such an opening remark, Teacher Meng can’t help but sigh. As for the reason, Mr. Meng thinks that children "watch too many model compositions, fail to carefully observe what happens in life, and their thinking is limited."

  In addition, there are several "high-frequency words" that always appear in children’s compositions regardless of time and occasion. For example: "wet eyes" and "red eyes". Among them, a first-grade child wrote: I came home from school, my grandmother told me to do my homework, and I finished my homework with wet eyes.

  Seeing this, people want to ask: son, why are you so wronged to finish your homework seriously? Is grandma fierce, or is homework too difficult to make you cry?

  Waiting for a companion for six hours, just to keep an appointment and go swimming?

  Children’s compositions are varied, and some even make up stories with their brains in order to finish their compositions. Teacher Zhong of a primary school told such a story — —

  That unit is about "sincerity", and I arranged for the children to write a composition on this topic. The content of a classmate’s composition is: On a hot summer day, two friends made an appointment to go swimming at 1 noon. One of the friends forgot the time because of his fun and didn’t go to the appointment. At 7 o’clock in the evening, this little friend suddenly remembered an appointment, hurried to the appointment, and found that his companion was still waiting in the same place. Therefore, he felt that his companions were sincere and he felt guilty.

  Teacher Zhong believes that most of this composition is made up. "This is a society with developed communication, not an era when messages are shouted and traffic is run. Isn’t this child going swimming just to keep his appointment by standing in the sun for six hours without eating or drinking? "

  Teacher Zhong reminded us that this story tells us that children can have imagination when writing a composition, but they can’t exaggerate it. Logic is the most basic thing. You should observe more in your life, and you can read composition books, but you should have a wide range of ideas, so you can’t be stereotyped.

  More than 10 children saw the little boy "give up his seat" at the same time

  There are more than 10 children in a class in a primary school in Chengdu, and the same thing happened at the same time. Teacher Zhang, who teaches Chinese, told her own experience:

  The topic of that day’s composition was "Nobleness". Of the 40 compositions I received the next day, more than a dozen were almost identical, and the general content was: Today, I saw a little brother give up his seat to the old man on the No.56 bus, which made me admire his noble character very much.

  After reading these compositions, Mr. Zhang can only write a comment without mercy: at the same time, at the same place, more than 10 students saw the same little boy give up his seat to the old man. Children, you must have read the same composition book. Take it back and rewrite it!

  There are always shopkeepers standing for days waiting to refund customers’ money.

  Teacher Qu, a primary school in Chengdu High-tech Zone, also told an interesting story about propositional composition: "I once asked for ‘ Sincerity ’ Write a composition for the topic. It was the first time that students came into contact with the composition of direct proposition. Originally, I didn’t have much hope. As a result, the composition I received still made me stupid. " In the composition received by Mr. Qu, nearly half of the students in the class have the same routine in their compositions.

  The general meaning of the composition is: "One day I went to the grocery store to buy snacks (or stationery) and forgot to change. After two days, I remembered to go to the boss again and found that the boss was still standing in the same place waiting for me with change. Ah, the boss is really a sincere person. " In order to highlight the sincerity of the store owner, some students will also add some environmental descriptions, such as in the wind and rain or under the scorching sun. "Won’t the boss take an umbrella?" "Which store boss can stand for so long? Come to the office and tell me. " Teacher Qu wrote in the comments.

  Later, Teacher Qu checked online and found that the students’ routines were exactly the same as the first search result of "Sincere Composition" from Baidu. Teacher Qu reminded parents that children should actively guide them when writing their compositions, and they should not directly check or teach their children to check online.

  Besides cats and dogs, is there any other fun in your life?

  Teacher Xia from Hi-tech Zone shared her experience in composition teaching. "I left a composition for the students a few days ago — — What pleasures have you found in your life? In class, I gave examples at random to tell students about the fun of keeping pets, such as keeping cats and dogs. As a result, the essays handed in by the students were basically all about keeping cats and dogs, and those who didn’t keep cats and dogs kept small goldfish or turtles. Anyway, the whole class unified the fun of life very tacitly — — Raise small animals. "

  Teacher Xia said that this kind of composition was originally open-ended, and each student’s experience was different, so what he wrote should be different. "At that time, I just gave an example casually. I didn’t expect the whole class to quote directly. On the one hand, it shows that some students are habitually lazy and don’t think when writing a composition. On the other hand, it shows that most students are not very good at observing at ordinary times, and there is no material available when writing a composition. " Teacher Xia believes that students must write more compositions and be good at observing life. Usually, they can start with diaries and gradually cultivate their thinking and writing skills.

  How to solve the "set" of primary school composition?

  ■ Li Yunxia, Chinese teacher of Chengdu Tonghui International School.

  Writing practice in grade one: "Look at the starry sky, what do you see?" What did you think of? " Of the 41 essays, 17 wrote about the stars blinking in the sky, 12 wrote about the stars like various gems, and several wrote about the Big Dipper like a spoon. What about the imagination of first-grade children? What about the "write whatever you see" that I specifically told you before?

  As a primary school Chinese teacher, I can’t help but smile: the composition routine is deep! Before the teacher started teaching routines, the students were taught routines first.

  Looking back on these years, I have encountered quite a few composition routines. When I write about my mother, I will get wet when I open an umbrella. When I get sick in the middle of the night, I always carry my child to the hospital myself … … Mothers’ IQ is always not online in their compositions. No wonder they have white hair in their 30s. The red scarf is a necessary prop, whether it is to give up your seat on the bus or return the extra money, the red scarf must fly high at the critical moment.

  Of course, it’s no wonder they are. Think about yourself as a student before you became a teacher, didn’t you come over like this? The students of that year, today’s fathers and mothers, must have been passed by.

  Pass one set, and the routine will last forever.

  What pushes teachers and parents to the routine? This problem is too big, but in short: 1. Lack of rich accumulation. Pupils are young, most of them don’t have rich life experiences, and they don’t have a lot of time to read outside the schoolwork burden, so their compositions lack flowing water. Second, the composition needs personalized guidance. In the classroom, there are many people and time is tight, so the teacher may not be able to teach calmly. Outside the classroom, parents are limited by their abilities and may not be able to guide their children to express themselves individually.

  Routine can get immediate benefits, but it stifles the spirituality of children’s long-term development As a Chinese teacher, it is necessary to reflect and improve the composition in primary schools, no matter who practices it. Adhering to the practice of critical reading and creative writing is the foundation, being familiar with children’s psychology, creating activity design as an arm, and making primary school composition dynamic and open. Teachers advocate true composition and expression, and guide children and parents with "truth" as the standard Parents abandon the pretence in adult society, do not interfere or impose, and let their children observe the world and experience life from the perspective of children. When teachers and parents give up routines, children will naturally restore their unruly personality. At that time, who can do routines?
