　　"In the next decade, the scientific and technological work in colleges and universities will achieve another leap, and it is far from enough to answer the questions of the times of marching into the forefront of world science and technology, serving the country’s major strategic needs, and serving the high-quality development of the economy and society." On July 19th, at the press conference of the Ministry of Education introducing the reform and development effect of science and technology innovation in colleges and universities in the past ten years, Lei Chaozi, director of the Department of Science, Technology and Information Technology of the Ministry of Education, pointed out that the Ministry of Education will focus on strengthening organized scientific research, accelerate the building of national strategic scientific and technological strength, and provide strong support for the construction of important talent centers and innovative highlands in the world and the self-reliance of high-level science and technology.

　　Since the 18th National Congress of the Communist Party of China, as an important part of the national innovation system, colleges and universities have effectively supported the development of education, science and technology, economy and society in China. One of the highlights is organized scientific research.

　　Lei Chaozi explained that from the guiding ideology, organized scientific research is to aim at the international scientific and technological frontier and the major needs of the country, and to change what I wanted and could do in the past into what the country needs me to do. Around the "four orientations", organize major tasks, build a large platform according to the needs of the tasks, build a large team based on the large platform, and continue to tackle key problems for a long time. Its fundamental purpose is to achieve continuous major original breakthroughs in basic research and lay a solid foundation for building a strong country in science and technology; Technological innovation should truly meet the national strategic needs, make up shortcomings and forge long boards, enhance the core competitiveness of China’s industrial development, and support high-quality economic and social development.

　　For example, Rong Zeng, vice president of Tsinghua University, said that the Institute of Nuclear Energy and New Energy Technology of the school has always adhered to the scientific research organization model of "tackling key problems by big teams and crossing disciplines". After more than 30 years of hard work by three generations and hundreds of scientists, the world’s first intrinsically safe modular high-temperature gas-cooled reactor nuclear power plant jointly developed and built with China Huaneng and China National Nuclear Corporation was connected to the grid for power generation in December last year, which realized the leap from "running with" to "leading" in this field. Professor Tsinghua University Lu Xinchun’s team has been deeply involved in the field of chemical mechanical polishing technology for a long time. The company whose scientific research results have been transformed is the only high-end semiconductor equipment manufacturer in China that can provide 12-inch CMP commercial models, breaking the monopoly of international giants in this field for decades.

　　After the outbreak of COVID-19, Tsinghua University quickly organized and set up 18 scientific research and anti-epidemic commandos, and achieved many achievements. China’s first anti-Covid-19 antibody drug successfully developed by Professor Zhang Linqi’s team has been approved by National Medical Products Administration for emergency listing; The mobile laboratory for nucleic acid detection developed by Academician Cheng Jing can complete the sample detection within 45 minutes; Academician Rao Zihe discovered and reconstructed the complete form of Covid-19 transcription and replication machine for the first time in the world, which provided key support for developing broad-spectrum anti-Covid-19 drugs.

　　Sun Qingwei, vice president of Peking University, also said that the school has made great efforts to guide scholars to focus on practical problems facing economic and social development and national security. A number of teams aim at national needs to promote innovative research in the fields of graphene material preparation, photoelectric device devices, gallium nitride semiconductors, high-end medical equipment, biological breeding of wheat and fruits and vegetables, and digital economy. Academician Mei Hong’s team invented the "subversive" black box interoperability technology in the key core technologies of big data fusion; Academician Gao Wen’s team has established an international standard for China’s independent intellectual property rights in the field of ultra-high definition video coding and decoding. "Strengthening organized scientific research is the top priority in Peking University’s scientific and technological innovation work." Sun Qingwei said.

　　Lei Chaozi pointed out that in the next step, organized scientific research in colleges and universities should make efforts to achieve major breakthroughs in original innovation, to overcome the basic theory and key technologies of the "stuck neck" problem, to serve the national regional innovation and development strategy, and to enhance the core competitiveness of industrial development, so as to realize the transformation and upgrading of scientific and technological work in colleges and universities.

　　The summer vacation is about to return to zero. These days, not only students who have not finished their homework, but also novice teachers who are about to take over the first batch of students in their lives are in a state of intense preparation. For the new semester that will start soon, their hearts are both looking forward to and uneasy.

　　Jiang Li, a teacher at Dinglan No.2 Primary School in Hangzhou, went to Qianbao reporter to tell her recent distress. Because Mr. Ding found that the "opening gift" that he started preparing for freshmen early may not be used.

　　It is a difficult problem for freshmen to learn pinyin.

　　She racked her brains to think of a way.

　　Teacher Jiang is a post-1995, who just joined this year. After the new semester begins, she will be the Chinese teacher and head teacher of Class 1 (5) in the school.

　　Because he is a novice, this summer vacation, Mr. Jiang has almost no rest and has been preparing for the new semester. Nowadays, all primary schools advocate zero-based admission, regardless of pinyin or literacy, they begin to learn after entering primary school. Therefore, when preparing lessons, Mr. Jiang thought a lot of countermeasures for the problems that zero-based students often encounter when they are beginners.

　　"For children in grade one, pinyin is very difficult to learn. Because letters are too abstract for them, it is difficult to establish a connection between letters and pronunciations, and many letters with similar shapes and sounds are easily confused. " Teacher Jiang said.

　　This summer vacation, she has been thinking about pinyin. How can we help children learn pinyin effectively?

　　Not long ago, when practicing the standard writing of pinyin, Teacher Jiang had an epiphany and came up with a way — — Hand-drawn cartoon pinyin table.

　　"In math textbooks, in order to let children remember the writing of numbers, each number will be integrated into cartoon pictures. Pinyin and numbers are abstract symbols. If pinyin letters are also integrated into cartoon patterns, they may have the same effect. " Teacher Jiang explained.

　　After having an idea, she immediately started to work and spent an hour to finish the preliminary drawing of the cartoon pinyin table. On this pinyin table, some common animals or articles are painted, and one or two pinyin letters are "inlaid" in each pattern. "Now this is just a sketch. I’m going to ask the art teacher for help to further beautify and simplify the pattern, and then use it as a teaching tool for students to consolidate their knowledge and expand their thinking." Teacher Jiang said that she also considered letting students draw together, and the "mosaic" way of patterns and letters was designed by the students themselves.

　　I have to say that this is a very creative idea. Adding vivid teaching methods such as pictures, jingles and finger dancing to the classroom can help junior children enjoy the class more quickly and develop their imagination.

　　However, Mr. Jiang soon found that his "opening ceremony" carefully prepared for the students was probably not used.

　　More than half the students in the class.

　　I finished learning pinyin in advance.

　　"I know that some students will definitely learn Pinyin in advance during the summer vacation, but the proportion should not be too large, and even if they want to learn, they will not learn it systematically." Teacher Jiang said.

　　These two days, she made a home visit to the students in her class, and this idea was completely subverted. "I found that more than half of the students in the class have almost finished learning Pinyin in advance." During her home visit, she specially brought her textbooks to check on the spot. Many students who have studied pinyin have mastered the most difficult polysyllabic pinyin and can basically spell it freely.

　　"I can understand the anxiety of parents who are afraid that their children can’t keep up with the start of school, but every teacher will prepare lessons according to the progress of the class before class. Such advanced learning will disrupt the teacher’s teaching plan." Teacher Jiang said helplessly. In her opinion, such advanced learning is not necessarily good for children.

　　"In class, I will abide by the barrel principle and take students who have not mastered pinyin as the standard. I will not give up those who have not learned because most people have learned it." Teacher Jiang said. Moreover, during her home visit, she found that many students’ pronunciation was not standard when they were receiving off-campus training because the teacher didn’t teach them seriously. After all, Pinyin is the most basic thing in Chinese learning. If there are mistakes at the beginning, it will be more difficult to correct them later, which will also have a negative impact on children’s future study.

　　After discovering this problem, Mr. Jiang was busy again, and the lesson plans that had been prepared for more than half a month needed to be readjusted.

　　"In the past, preparing lessons was based on zero-based children. Now we need to redesign the way of class according to the differences in students’ learning level." Teacher Jiang said. In the future teaching, she will pay more attention to students with zero starting point and cultivate their interest in learning as soon as possible. For those children who have learned pinyin, she will pay attention to their learning methods and spelling methods, and get rid of some incorrect places, so that they can apply pinyin to Chinese learning as soon as possible.

　　"You can also let the children who have learned Pinyin study with other children to form a good learning atmosphere." Teacher Jiang said. (Reporter Jianwei Liang correspondent Chen Hongcheng)

Chang Kai, a takeaway rider, recently changed his post. He parked the takeaway electric car, left his small home, dragged a big suitcase full of laundry, and joined the "Youth Guarantee Commando" in Chaoyang District to become a volunteer. In a warehouse in Sunhe Township, he skillfully packed protective clothing, masks, gloves and other epidemic prevention materials and distributed them to the "Dabai" who worked in the control area.

Since the current epidemic in Beijing, there are still many volunteers from all walks of life like Chang Kai fighting in the front line of epidemic prevention, including social workers, real estate agents, take-away riders, and courier brothers … The reporter learned from the Chaoyang Youth League Committee that three youth epidemic prevention volunteer service teams have been set up, including the youth insurance commando team, the community bayonet supervision service team and the migrant volunteer service team. As of November 17th, Chaoyang Youth League Committee recruited 979 young volunteers from 26 volunteer teams to participate in epidemic prevention and control through socialization of various youth communities.

Material support point: takeaway riders should contribute to epidemic prevention.

Chang Kai has a WeChat group named "Beautiful Chaoyang Knight". The group friends are all courier brothers and takeaway riders from Chaoyang District who have won the title of "Beautiful Chaoyang Knight". The group often forwards notices of public welfare activities, and Chang Kai always takes an enthusiastic part as long as he has time.

On the evening of November 10th, Chang Kai suddenly saw a message in the group that Chaoyang Youth League Committee had called volunteers to support this round of epidemic prevention and control. "In the last round of the epidemic, I also signed up as a volunteer. At that time, I was a’ big white’ in a community in Wangjing Street. So when I saw the recruitment notice on the evening of the 10 th, I signed up without hesitation. " In 2018, Chang Kai came to Beijing to become a takeaway rider. In his view, the rider’s specialty is that he is very familiar with the streets and lanes, and the efficiency of receiving goods is high. "It is indispensable to participate in the prevention and control of the epidemic. This is my specialty. I must sign up."

Simply packed up and changed clothes. At 2 pm on November 11th, Chang Kai and several other volunteers arrived at the material support point. This is a warehouse temporarily converted from a gym in Sunhe Township, Chaoyang District. Volunteers divide the gym into No.1 warehouse and No.2 warehouse according to the area, in which No.1 warehouse stores protective clothing, and No.2 warehouse stores masks, screens, gloves, etc. These materials are neatly stacked on the wall according to different categories. Loudspeakers are also stored on the shelves of the warehouse, which are also good helpers for "Dabai" to work in the control area.

Every morning is the busiest time for volunteers. They have to distribute the materials to Dabai in the control area according to the quantity on the form. In order to avoid mistakes in busy work and improve the efficiency of distribution, Chang Kai and his colleagues divide the work of "dispatching". "For example, I am responsible for distributing protective clothing, and the other two colleagues are responsible for distributing masks and gloves, which is fast and not easy to make mistakes." Chang Kai said.

After the "morning rush", the pace of work of volunteers slowed down. However, Chang Kai, who is restless, always goes to the volunteer leader of the security point for work, either cleaning the warehouse again or checking the inventory with the material list. During the epidemic, many caring units donated epidemic prevention materials, which also need volunteers to classify and transport them to the warehouse for storage.

"If doctors and nurses who directly face infected people are regarded as the’ first post’ of epidemic prevention and the’ big white’ of the community is the’ second post’, then our volunteers are the’ third post’. Each of us is like a link in the’ chain’, and no one can drop the chain, but we must twist it into a strength and rush forward. " From November 11th to today, Chang Kai has been working in the security point for a week. "I will continue to be a volunteer. I want everyone to know that our takeaway riders will not only deliver food, but also do good public welfare and contribute to epidemic prevention."

In the closed control area of Chaoyang District, there are also volunteers. Guo Lingjiang, deputy secretary of the Communist Youth League Committee of non-public enterprises, has participated in many public welfare emergency distribution activities. In this epidemic, he called on riders to join the volunteer team to provide material distribution support for the closed control area of Anzhen Street.

It was not easy at first, Guo Lingjiang told reporters, "Some riders were unable to take orders because of the pop-up window, and there was a shortage of capacity." What if there are not enough hands? Guo Lingjiang’s company is a take-away food delivery enterprise, so he held an emergency meeting with his colleagues to find ways to optimize the transportation capacity and deploy human support from other areas such as Haidian. In the end, it not only provides voluntary service for material distribution in the closed control area, but also ensures the daily distribution needs of citizens.

At present, Guo Lingjiang has called on more than 50 young people to join the volunteer team. "We are ready, and we will rush up as soon as necessary." Guo Lingjiang said.

"44th Street": Do a good job of telephone flow, and don’t add chaos to the community.

There are 43 townships in Chaoyang District, but there is a "44th Street" in Baiziwan. In this special "street", about 50 volunteers form a youth volunteer service team by telephone to provide strong support for epidemic prevention and control in townships.

Speaking of the origin of the name "44th Street", Yang Jie, a social worker of the Community Youth Exchange, said with a smile: "We 50 people come from 43 townships in the whole district, so we simply named our service team" 44th Street ".

Volunteer Yang Jie (right) and her colleagues are making a phone call. Photo courtesy of respondents

In order to do a good job in telephone streaming, Chaoyang Communist Youth League set up a hotline call platform for 48 hours, giving full play to the advantages of social mobilization, coordinating the Youth League Committee of Chaoyang District Lawyers Association to provide site and workstation support, and coordinating the enterprises where the Youth League Committee members are located to set up a call center platform. The second-level non-governmental organizations also sent volunteers a public lunch.

Telephone traffic control is an important part of epidemic prevention and control. Yang Jie is an old traffic control volunteer, so in this volunteer service, she is mainly responsible for teaching the technical essentials of telephone traffic control to "novices" and filling in the traffic control form accurately as required.

Making a phone call seems to be a simple job, but it requires patience and meticulousness. Yang Jie said: "In the list we got, some people may need to stay at home for seven days, while others may need three days and two inspections. The situation is not the same. Moreover, some people in the form don’t have addresses in Beijing, so we have to ask carefully when doing the flow adjustment to confirm their specific addresses in Beijing, so that we can accurately feedback to the community. " Recently, the volunteer service team has increased its manpower, and everyone is divided into four groups to carry out telephone streaming. Every day, when colleagues finish the task of flow adjustment, Yang Jie always checks these lists again to see if there are any omissions.

Yang Jie worked as a volunteer in Chaoyang District CDC before. Compared with the last experience, she felt that the pressure was even greater this time. "The last time I worked with the teachers of the Center for Disease Control and Prevention, I could ask questions at any time. I always felt that the teachers could give us the bottom, and I was practical. This time, I am the team leader and also responsible for training. Without a disease control teacher around, I dare not have any omissions in my work. We must not add chaos to the epidemic prevention and control in the streets and townships because our work is not in place. "

The reporter learned from the Chaoyang Youth League Committee that the volunteers came from many caring enterprises in Chaoyang District, as well as universities such as Beijing Information Science and Technology University, university of international business and economics and beijing international studies university. In order to strictly abide by the epidemic prevention regulations of colleges and universities, college volunteers are currently conducting online volunteer service.

Community bayonet: real estate agents become health code inspectors, and residents give thumbs up.

These days, real estate agent Ding Guanghui runs the community more frequently.

"When I don’t take customers to see the house, I often run to the community, and I have to check whether the QR code of the bayonet meets the requirements." Ding Guanghui told reporters that after the current epidemic, he signed up for the "community bayonet supervision service team", whose main task is to check whether the community has achieved "one bite and one yard".

Before taking up his post, Ding Guanghui participated in online volunteer service training and realized the importance of "one bite and one yard" for accurate epidemic prevention and control. Therefore, after becoming a volunteer, Ding Guanghui regularly goes to the bayonet of each community, scans the QR code of the bayonet with his own health treasure to check whether it is normal or not, and then uploads the scanned code results to the information platform through the mobile phone.

Real estate agents and many residents in the community are old friends. When Ding Guanghui came to "scan the code", the neighbors in the neighborhood could not help but exchange greetings. Familiar uncles and aunts gave him thumbs up, and residents who used to buy real estate through Ding Guanghui even pulled him to chat. Ding Guanghui is very happy, because this job has been understood and cooperated by the residents, and he is more energetic as a volunteer.
