CCTV News:On April 27th, the national science and technology major special series news release activities — — The press conference of "Large Oil and Gas Fields and Coalbed Methane Development" was held in the Ministry of Science and Technology. Experts from the Ministry of Science and Technology, the Development and Reform Commission, the Ministry of Finance, the head of the oil and gas development project and the technical chief attended the press conference and answered questions from reporters.

　　Chen Chuanhong, director of the Major Special Office of the Ministry of Science and Technology, presided over the press conference, introduced the overall progress of major national science and technology projects, and pointed out that as an important starting point for implementing the innovation-driven development strategy, the oil and gas development project produced a number of major landmark achievements in the organization and implementation process, and achieved remarkable economic and social benefits, which opened up a new industrial development direction in the oil and gas energy field, effectively supported the national energy security, and significantly improved the upstream scientific and technological innovation capability of the petroleum industry.

　　Li Fanrong, deputy director of the National Energy Administration, introduced the overall implementation progress of the oil and gas development project. Oil and gas development project is the only major national science and technology project organized and implemented by enterprises. Under the leadership of the CPC Central Committee and the State Council, and under the organization and coordination of the National Development and Reform Commission, the Ministry of Science and Technology and the Ministry of Finance, we will adhere to the innovation-driven strategy, practice the scientific and technological research mode with enterprises as the main body and Industry-University-Research as the combination, gather the superior forces of the whole society for collaborative innovation, strengthen the combination of projects and demonstration projects, and comprehensively complete the overall goals and tasks of the Eleventh Five-Year Plan and the Twelfth Five-Year Plan. The three ministries and industry experts spoke highly of the organization, management and implementation of the special project.

　　Since the implementation of the special project, significant progress has been made in six major areas, including onshore oil and gas exploration, onshore oil and gas development, engineering technology, offshore oil and gas exploration and development, overseas oil and gas exploration and development and unconventional oil and gas exploration and development, with remarkable results.

　　First, six major technical series and 20 key technologies have been formed, 13 major equipment have been developed and 22 demonstration projects have been built, and China’s oil and gas exploration and development has entered a new era of innovation and development.

　　The second is to ensure that China’s oil production is rising steadily and natural gas production is developing by leaps and bounds. The output of crude oil increased steadily from 185 million tons in 2007 to 198 million tons in 2016, and remained the fifth largest oil producer. Natural gas production rose rapidly from 67.7 billion cubic meters in 2007 to 137.1 billion cubic meters in 2016, making it the sixth largest gas producer in the world.

　　Third, it has promoted the construction of national innovation system and enhanced China’s oil and gas independent innovation capability. It has formed a high-level R&D team with 100 enterprises covering the upstream technology of the petroleum industry, more than 50 universities of the Ministry of Education and more than 20 research institutes of the Chinese Academy of Sciences. Construction of 9 national, 23 provincial key laboratories and R&D centers and other high-level innovation platforms. Related achievements won 3 national special prizes for scientific and technological progress, 5 first prizes and 19 second prizes, applied for 2,143 invention patents, formulated 185 national and industry standards, and registered 722 software copyrights.

　　Academician Jia Chengzao, the chief technical engineer, mainly introduced the great progress in the exploration and development technology of marine and deep natural gas in China. Through special research, China has made substantial breakthroughs in marine and deep natural gas exploration and development technology, discovered and built a number of large gas fields, realized the leap-forward development of natural gas production, guaranteed national energy security, and promoted social and economic development and the construction of beautiful China.

　　First, a series of international advanced natural gas exploration and development technologies have been formed, and a number of large gas fields have been discovered and built.

　　First, innovative development of major technologies for marine carbonate oil and gas exploration and development, the discovery and construction of Anyue super-large gas field with the oldest geological age, Yuanba deep reef gas field and Puguang high-sulfur gas field in Sichuan Basin, and the growth of carbonate natural gas reserves in Tarim and Ordos basins.

　　Second, the development of deep natural gas accumulation theory and exploration and development technology in foreland thrust belt, especially the conquest of major exploration technologies such as deep-seated wide-line large-scale seismic acquisition and prestack depth migration in complex mountainous areas, has expanded the depth of natural gas exploration and development in Kuqa thrust belt to 8,000 meters, and found six large gas fields with a production capacity of 26 billion cubic meters under extremely thick saline strata, ensuring the safe and stable gas supply of "West-to-East Gas Transmission".

　　Third, major breakthroughs have been made in exploration and development technologies of unconventional natural gas such as tight sandstone gas and shale gas, and unconventional natural gas has become an important part of China’s natural gas production. For example, breakthroughs have been made in key technologies such as tight sandstone gas accumulation theory and reservoir fracturing reconstruction, which has realized the effective development of Sulige large tight sandstone gas field, with an output of 22 billion cubic meters in 2016; Technologies such as multi-stage fracturing and industrial development of horizontal wells have supported the effective development of shale gas fields such as Fuling and Changning-Weiyuan, with an output of 7.8 billion cubic meters in 2016.

　　Fourth, China has made great progress in key technologies and equipment for offshore deep-water exploration and development, discovered large gas fields such as Lingshui 17-2, and successfully developed the first deep-water gas field in the South China Sea — Liwan 3-1.

　　Since the implementation of the special project, China’s natural gas industry has achieved leap-forward development, and the accumulated proven geological reserves have doubled, from 6.1 trillion cubic meters at the end of 2007 to 12.98 trillion cubic meters in 2016, and the world ranking has risen from 14th to 9th. The annual output of natural gas in China has doubled, from 67.7 billion cubic meters in 2007 to 137.1 billion cubic meters in 2016, and the world ranking has risen from ninth to sixth. The proportion of natural gas in the primary energy consumption structure increased from 3% to 6%, and increased to 8.3 ~ 10% at the end of the 13th Five-Year Plan. Make great contributions to China’s energy structure optimization and environmental improvement.

　　In addition, the exploration and development of offshore deep-water natural gas in China has made great contributions to safeguarding China’s maritime rights and interests and implementing the national marine strategy; It has cultivated new industries such as the development of unconventional natural gas resources such as shale gas and coalbed methane in China, such as the development of marine shale gas in the south, which has guaranteed the gas consumption of local industries and residents and promoted the development of local economy; The large-scale development of coalbed methane has become an important clean energy in Shanxi Province, and has made important contributions to the development of low-carbon and green economy.

　　During the "Thirteenth Five-Year Plan" period, we will further strengthen the theoretical and technical research on natural gas exploration and development, constantly overcome the bottleneck technologies of deep-seated onshore, deep-water offshore and unconventional natural gas exploration and development, provide technical support for ensuring the steady growth of national natural gas reserves and production, and promote the further optimization of national energy structure and the sustained and stable development of national economy.

　　Sixteen years have passed, and to Zhu Yongxin’s delight, the concept of reading has been accepted by more people, the atmosphere of reading for all is getting stronger and stronger, and the trend of continuous decline in reading rate has been curbed.

　　Beijing, March 11th (Reporter Yang Peiying) In an interview with Committee member Zhu Yongxin for nearly an hour, the two most frequently mentioned words were "reading".

　　From "the image spokesman of reading for all" to the active explorer of new education, to launching the "Reading for the Future Plan" and calling on more reading promoters, the personal practice of reading and the drum call for reading for all have become a part of Zhu Yongxin’s life. Whether busy at work or on a business trip, reading and writing at 5 o’clock every morning is his unshakable habit.

　　Since the two sessions in 2003, Zhu Yongxin, member of Chinese People’s Political Consultative Conference and vice chairman of the Central Committee of the Democratic Progressive Party, has called for the establishment of a "national reading festival" for 16 consecutive years, taking reading for all as a national strategy, establishing a national reading fund, establishing a national reading promotion committee, and strengthening the construction of community libraries … … A series of proposals and suggestions on reading.

　　In order to make children grow up better, Zhu Yongxin, member of Chinese People’s Political Consultative Conference and vice chairman of the Central Committee of the Democratic Progressive Party, wrote "an initiative to be a happy scholar." Photo by Future Network reporter Yang Peiying.

　　Sixteen years have passed, and to Zhu Yongxin’s delight, the concept of reading has been accepted by more people, the atmosphere of reading for all is getting stronger and stronger, and the trend of continuous decline in reading rate has been curbed.

　　For 16 years, we have consistently carried out the "Reading Festival" to the end.

　　It has been consistent for 16 consecutive years, and there are really not many representatives or members who advocate a topic.

　　At the two sessions this year, Committee member Zhu Yongxin once again put forward a proposal on establishing a national reading festival. He said that the National Reading Festival is to promote reading in daily life to a ceremony. "Just as the two sessions are the political Spring Festival of China people, the National Reading Festival should also become the spiritual Spring Festival of China people."

　　After sixteen years of consistent persistence, Zhu Yongxin clearly knows the important role of reading in life. His most classic sentence "A person’s spiritual development history is his reading history, and a nation’s spiritual realm depends on its reading level." This paper profoundly expounds the important significance of reading to human growth and national development. Zhu Yongxin believes that there are many paths and methods to improve national quality, but the cheapest, most direct and most basic one is reading.

　　At present, the proposal to establish a national reading festival and advocate reading for all has been jointly appealed by more than 100 members of Chinese People’s Political Consultative Conference.

　　In order to promote comprehensive reading, this year, Zhu Yongxin also submitted a proposal on "promoting high-speed rail reading". In Zhu Yongxin’s view, high-speed rail has become a part of people’s lives, but at present, the reading materials provided on high-speed rail are very limited, and the quality and quantity are not optimistic. "These public readings are an important way to spread reading culture, which can effectively enhance people’s reading awareness and encourage people to develop reading habits." Zhu Yongxin believes that China is the largest and most advanced high-speed rail country in the world, and the high-speed rail carriages are comfortable, hygienic and safe, providing a good reading environment. At such a time, you can read with peace of mind, and the establishment of such a system can enable the people to develop better habits.

　　Although the concept of reading has been accepted by more people, in Zhu Yongxin’s view, in-depth reading may not be enough. The most fundamental reason is that the whole society’s understanding of reading has not really reached the designated position. In terms of education, examination is still regarded as an important direction to a great extent, and reading has not received due attention.

　　But Zhu Yongxin believes that the efforts will not be disappointed. In the diary of member Zhu Yongxin published in the newspaper of the Chinese People’s Political Consultative Conference, he wrote — — Carry the reading festival to the end, and I will continue to work hard for reading drums and shouts.

　　Children’s reading determines the future of the nation.

　　In life, Zhu Yongxin also practices the habit of reading every day with such persistence and perseverance.

　　Get up at about five o’clock every morning, insist on writing and reading, and you must take all kinds of books you read with you every trip, and recommend a good book worth reading in Weibo every day.

　　Zhu Yongxin told the reporter of Future.com that good habits are the best wealth in a person’s life. "It’s basically very quiet from five in the morning to eight in the morning, and no one bothers you, no work, no phone calls. You can calm down and write."

　　There is still a long way to go to get people to develop the habit of reading. At the end of 2017, Zhu Yongxin’s Institute of New Education and the Central Committee of the Communist Youth League launched the "Reading the Future, Children’s Reading Program". Zhu Yongxin said that he hopes to train more promoters who take teenagers to read, so that more people can become reading volunteers and promoters.

　　Zhu Yongxin believes that "the length of childhood determines the height of a country. The depth of children’s reading determines the height of national spirit. In this sense, children’s reading determines the future of the nation. "

　　Reading ability is very important for children’s growth. "By reading, he can go to a wider world, see things outside him, and see from ancient times to the present, from the middle to the outside, and he will see farther, which will give him a better vision. Secondly, his writing ability is not only writing, but also thinking ability. Real writing begins with thinking and writing.

　　However, in the era of mobile internet, mobile phone reading can be seen everywhere, and many people don’t have a lot of time to settle down and read and write. For teenagers known as "Internet aborigines", it has become the norm to acquire knowledge through mobile phones and mobile terminals.

　　In Zhu Yongxin’s view, the trend of digital reading is irreversible, and it is understandable for children to accept digital reading. However, he still advocates that paper reading should not be thrown away, especially primary and secondary school students should learn to read paper books quietly as much as possible and form such a habit, because excessive dependence on electronic media will make it difficult for children to really concentrate, and in addition, it will have some adverse effects on eyes, thinking and attention.

　　Promote children and adults to read together, and the government promotes bibliography development

　　In reality, many primary and middle school students have a heavy academic burden and don’t have much time to settle down and study. A reading survey for primary and secondary school students, teachers and parents shows that 74.85% of children like reading, but more than half of them have no time to read. In the question "What is the reason that prevents you from reading?" In the middle school, 50.59% of the children said that they had "heavy studies and no time and energy" to read, and "the problem of heavy extracurricular burden of primary and secondary school students" was even written into the 2018 government work report.

　　In this regard, Zhu Yongxin believes that the heavy academic burden is on the one hand, and the key point is that many parents don’t realize the importance of reading. They prefer to spend their time in tutoring and learning a lot of repetitive content in the classroom. From the perspective of school education, there are a little more simple exercises and repetitive exercises, which really makes students have less time to study. It is also necessary to change our classroom and change our working methods.

　　In order to let children know what good books are, since Zhu Yongxin became the provost of Suzhou University in 1993, he has promoted reading in the whole school by recommending bibliographies. Over the years, Zhu Yongxin has been doing the research and development of recommendation books.

　　Since April, 2011, Zhu Yongxin and his new reading research have successively published basic reading books for primary school students in China, basic reading books for children in China, basic reading books for middle school students in China, basic reading books for entrepreneurs in China, basic reading books for primary and secondary school teachers in China and basic reading books for parents in China.

　　Zhu Yongxin thinks that the development of bibliographies is a particularly important task. In the information age, the richer the information, the easier it is for people to get lost. The development of bibliography is to provide a scientific catering plan with comprehensive nutrition for a person’s spirit, which is convenient for people to follow the map. He suggested that the government further promote the research of various reading majors, promote the development of bibliographies, purchase services for the research results of various professional non-governmental organizations, and promote the deepening of reading in time.

　　In the face of the current situation that more and more children prefer online games to reading, Zhu Yongxin believes that no child is born to like this and that, which requires parents’ guidance and parent-child reading to cultivate children’s reading habits.

　　"This is the most effective way. Many of our mothers buy a lot of books and throw them to them. He may not be interested in reading them. You can discuss them with your children, inspire them together, ask him questions, and discuss them with him. You may take him to study. In addition, you should look for books he likes. Every child has a different appetite. If you can find books that suit his appetite, you may take him to the book world. If you find them from the beginning, you are not interested.

　　In this year’s proposal, Zhu Yongxin also suggested taking children as the center and promoting children’s reading with adults. Zhu Yongxin hopes that children can love paper reading through parent-child reading, teacher-student reading and team reading, so that reading promotion can directly and effectively influence the development of reading habits of adults around children through children’s influence and supervision.

　　In Zhu Yongxin’s view, it is also very important to guide parents’ education. Zhu Yongxin pointed out that the most important thing is that parents should be role models for their children, parents should grow up with their children, and parents should know what kind of education is good.

　　Advocating reading for all is the spiritual index to cultivate cultural self-confidence and realize national rejuvenation. More persistent watchmen are needed to drum up and shout around the atmosphere of reading for all.

　　The safety of teenagers’ holiday internet is worthy of attention.

　　Our reporter Zhou Xiaopeng

　　With good results in the senior high school entrance examination, Xiao Zhang, who lives in Shijiazhuang, Hebei Province, was successfully admitted to the target high school, but before long, this joy was replaced by constant quarrels between him and his mother. In the mother’s view, during the holiday, Xiao Zhang was either a computer or a mobile phone every day, and spent too much time indulging in the Internet. Xiao Zhang, on the other hand, is quite opposed to this: I finally have a holiday to relax, so why can’t I play more mobile phones and games?

　　In fact, for this generation of teenagers who were born with a mouse and grew up with their mobile phones, the internet has become an indispensable part of their lives, especially when they enter the holidays, and the time spent touching the internet has increased greatly, making it easier for them to indulge in the internet and cannot extricate themselves. In addition, because teenagers generally lack social experience and don’t know how to protect personal privacy, they are more vulnerable to bad information, online fraud and even illegal acts on the Internet.

　　Experts told the "Legal Daily" reporter that when children enter the holiday "mode", they can spend more time online and relax their entertainment appropriately, but they must make reasonable plans and not be "cyber slaves". Schools and parents should actively guide teenagers to surf the Internet healthily, so as to use the Internet safely, in a civilized and healthy way.

　　Prevent online game addiction

　　Looking up at the computer, looking down at the mobile phone, regardless, playing games all night, this is a true portrayal of many teenagers’ holiday life. In June 2018, online game addiction was officially declared as a mental illness by UNESCO. Statistics show that teenagers between the ages of 12 and 16 are high-risk groups of Internet addiction. The proportion of global teenagers who are over-reliant on the Internet is 6%, and the proportion in China is close to 10%.

　　When he noticed this data, Zhang Rucai, a deputy to the National People’s Congress, was really shocked. "The bad content of online games is imperceptibly affecting teenagers." Zhang Rucai told reporters that the development and operators of online games only seek to maximize economic benefits, which has caused unhealthy online games to become a public hazard that destroys the physical and mental health of young people.

　　In 2018, Zhang Qingbin, a representative of the National People’s Congress, received a petition signed by many parents on strengthening the management of online games and legislating as soon as possible, calling for legislation to save many children, which made him systematically pay attention to the problem of teenagers indulging in online games. Zhang Qingbin said that he really felt the seriousness of this problem in his hometown in rural areas. "Many teenagers drop out of school early because they are addicted to online games and become idlers. There are also many teenagers who have all kinds of psychological problems and even make some excessive behaviors because they are addicted to online games." As a result, Zhang Qingbin launched research, went deep into schools and communities to listen to the voices of the masses, and consulted with departments such as culture and online information to understand the situation. "Many online games design various links according to people’s psychological needs, and induce players to fall into addiction layer by layer, which is difficult to resist the temptation for teenagers’ immature psychology." Zhang Qingbin said.

　　In medicine, internet addiction is a clear concept, which usually refers to indulging in online games. When online games are stopped, withdrawal symptoms such as irritability, anxiety and sadness appear. Lose interest in other hobbies before, even if you understand the impact of the game on yourself, you still focus on the game; Use online games to escape or relieve negative mood.

　　In the view of Xiao Zhang’s mother, Xiao Zhang has already had some symptoms of Internet addiction. "The child’s addiction to the Internet not only leads to the damage of the parent-child relationship, but also aggravates the parent-child conflict. More seriously, his daily life rules are completely broken, and he is afraid that a holiday will cause him various psychological obstacles." Xiao Zhang’s mother said.

　　Beware of illegal network infringement

　　"Can you send me a nude photo of your bust? I promise to treasure it myself and not let others see it." Last winter vacation, Xiaomei (a pseudonym), a 14-year-old junior high school student, met a small town (a pseudonym) who claimed to be 15 years old on a short video App. After the two sides closed each other, the exchange was transferred to QQ. Just after half a month of understanding, the town made such a request to Xiaomei for the first time.

　　Although she was worried, Xiaomei agreed to the other party’s request, and this became the beginning of a nightmare. Since then, the town has been making unreasonable demands, from naked photos to naked videos, and the original pleading has also become a threat.

　　Xiaomei’s reticence and trance made her mother discover the clue. After repeated questioning by her mother, she confessed everything, and Xiaomei’s parents immediately called the police. The police of the Criminal Police Brigade of Qiaoxi Public Security Bureau in Zhangjiakou City, Hebei Province, who was in charge of the case, launched an investigation through the QQ number of the suspect and quickly locked the suspect Yang and arrested him.

　　The police found out that Xiaomei’s so-called friend town was completely fictional by Yang, and the school, information and photos were all false. Yang’s real identity was from Tianjin, born in 1978, married and had a criminal record of theft. Yang often chats through various online social software and chooses a minor like Xiaomei to cajole and threaten, and Xiaomei is not his only chat object. At the end of March this year, Yang was prosecuted by the People’s Procuratorate of qiaoxi district, Zhangjiakou City for allegedly molesting minors.

　　"It is best for minors not to make friends online." In the preliminary investigation, faced with the interrogation of the prosecutor of qiaoxi district Procuratorate in Zhangjiakou City, who was in charge of the case, Yang confessed his illegal behavior, and also said that minors should take warning. On June 12, the court made a first-instance judgment, and the defendant Yang was convicted of child molestation and sentenced to two years and six months in prison.

　　Not only that, because teenagers’ physical and mental development is not fully mature, their vigilance is low, and they are easy to trust others, so they can easily become "things in the bag" of cyber criminals. In addition to browsing unhealthy web pages and contacting bad information on the Internet, all kinds of fraud such as false enrollment, part-time job, recruitment, etc. often target at the student group. For example, defrauding the client’s funds in the name of online billing is a common online fraud method used by scammers during the summer vacation. In fact, these fraudulent means are not novel, but they have long appeared in holidays, and students are deceived every year.

　　"Don’t click on pop-ups and unknown links that appear in the process of surfing the Internet at will. You should be vigilant when making friends online, don’t expose your own and others’ private information, don’t threaten, insult or slander others on social platforms, don’t make or spread unconfirmed information, and stay calm and confident when encountering cyber bullying, and communicate with teachers or parents in time … … These should be common sense when teenagers touch the net. " Zhang Qingbin said.

　　Guide children to use the net safely.

　　Wu Guiping, chief of juvenile criminal prosecution department of qiaoxi district Procuratorate in Zhangjiakou City, said that Internet social interaction is widely used now. As parents, they should pay more attention to their children’s mental state and make friends, and make timely safety education, let them know the uncertainty of online friends through equal communication, and tell their children the principles of making friends in the virtual world. If you don’t tell each other your real identity information easily, you can’t send photos and videos involving privacy to each other.

　　"Parents should also consider the psychology of adolescents. They are no longer satisfied with their parents’ care and love, but have more needs to communicate with others. I hope that friends with similar aspirations and interests can’t blindly suppress this desire to make friends. We must correctly guide and help them and inform them of the bottom line and principles of communication." Wu Guiping said frankly.

　　In fact, the network security literacy level of minors is closely related to personal personality factors, family factors and school environment. In addition to preventing internet addiction and using the internet scientifically and rationally, protecting personal information, spreading positive values, not believing in rumors and not spreading rumors should also become the proper meaning of safety education for minors using the internet. In this regard, both family education and school education should actively make up a lesson.

　　According to Chu Zhaohui, a researcher at the Chinese Academy of Education, minors have realized the convenience of the Internet early, but they have no independent ability, which is the main reason for Internet addiction. "For parents, it is necessary to give their children a sense of rhythm in regulating the use of the Internet, such as giving them a fixed time to browse the Internet every day and giving guidance to what they browse, so that they can form their own ability to plan their lives as soon as possible." Chu Zhaohui said.

　　Chu Zhaohui believes that at present, in most primary and secondary schools, mobile phones are forbidden to be brought into the campus. How to spend their spare time and holidays is a test for students and parents. "Some parents will regard mobile games as a reward for their children. I think this is a misunderstanding. It is very important to enhance children’s autonomy and enrich their lives. "

　　At this year’s National People’s Congress, Zhang Rucai and Zhang Qingbin both put forward suggestions on strengthening the management of online games and legislating as soon as possible, and suggested that the National People’s Congress Standing Committee (NPCSC) should introduce the online game management system to protect teenagers’ physical and mental health, the network protection law for minors and other relevant laws and regulations as soon as possible.

　　"It is necessary to strengthen government supervision, improve the online game real-name authentication system, and purify the online game content and network environment." Zhang Qingbin said that we can learn from the examination and approval system for film and television works, strictly examine and approve online games, and at the same time introduce functions such as "face-brushing camera" to prevent registered users who do not match their actual identities from logging in.

　　Relevant experts pointed out that during holidays, parents should guide their children to establish correct network values and teach them to learn the behavior of using the internet safely. Parents and children can discuss and formulate mutually acceptable online time, which will not affect their daily life and rest, so as to establish a good time concept; Parents should pay more attention to their children’s online process, listen more and admonish less, avoid damaging the parent-child relationship with critical words, spend time with their children, and cultivate their interest in the real world, instead of focusing on the virtual online world.

　　Xinhua News Agency: Basketball originated in 1891 and was invented by American PE teacher Dr. james naismith. At the 1936 Berlin Olympic Games, the men’s basketball game was listed as an official event for the first time. Women’s basketball was not formally included until the 1976 Montreal Olympic Games. There are only two gold medals for men’s and women’s teams in the Olympic Games.

　　In the past 16 men’s basketball and 8 women’s basketball Olympic Games, the American men’s basketball team won 12 championships, the Soviet men’s basketball team won 2 championships, and the Yugoslav and Argentine men’s basketball teams won 1 championship each. The American women’s basketball team won five championships, the Soviet women’s basketball team won two championships and the CIS women’s basketball team won one championship. China’s best result in the Olympic Games is that men are eighth (26th Atlanta Olympic Games and 28th Athens Olympic Games) and women are second (25th Barcelona Olympic Games).

　　Rules of the game: The Olympic basketball game consists of four sections, each of which lasts for 10 minutes. If the score is equal at the end of the fourth quarter, one or more 5-minute overtime will be needed to continue the game until the winner is decided. There is no limit to the number of substitutions for each team in the competition; Pause in the first half, each team can get 2 times; You can get 3 times in the second half; At any time in each overtime, each team may have a timeout.

　　There are two kinds of violations of competition rules in basketball games: violations and fouls. Violations include: walking with the ball, illegal dribbling, punching or kicking the ball, returning the ball to the backcourt, and 3 seconds violation. In addition, it also includes the following:

　　5-second violation: the attacking player must throw the foul ball within 5 seconds; Or when being closely defended, you must pass, throw or dribble within 5 seconds; When the referee hands the ball to the penalty player, the player must make a shot within 5 seconds.

　　8-second violation: A team must make the ball enter the frontcourt (the opponent’s half) within 8 seconds from controlling the live ball in the backcourt.

　　24-second violation: Every time a player gets a live ball on the court, the team must try to shoot within 24 seconds.

　　Interference score: When the ball shot (free throw) falls in flight and is completely above the level of the hoop, the players of both sides must not touch the ball. When the shot ball touches the rim, neither team member can touch the rim or backboard, reach through the rim from below and touch the ball, and shake the backboard and the rim. If the attacker violates this rule, the basket will be invalid, and the ball will be awarded to the other side to throw the ball out of bounds in the extension of the free throw line; If the defender violates this rule, regardless of whether he hits the ball or not, the shooter (free throw) will be awarded points.

　　Fouls include the following situations:

　　1. personal foul: If a player who didn’t shoot is fouled, the non-foul team will throw the ball into the foul area near the foul place to restart the game. If the foul team is in the state of team foul punishment, it should be awarded two free throws to the players who have not shot, instead of throwing the ball into the bounds. If a player who is making a shooting action is fouled, if the shooting is successful, points shall be counted and an additional free throw shall be awarded; If you miss the shot, you will be awarded 2 or 3 free throws according to the location of the shot.

　　2. Technical foul: it is a non-contact foul, such as ignoring the referee’s warning; Violate the referee, technical representative, record desk personnel or team seat personnel impolitely; Use language and manners that offend or incite the audience; Teasing the opponent’s team members or shaking hands near the eyes of the opponent’s team members will hinder their vision; Deliberately touching the ball after it passes through the basket to delay the game; Obstruct the rapid execution of throwing the ball into bounds to delay the game; Fake a fall to fake a foul, etc. The penalty for the technical foul is to award the opponent two free throws, and then throw the ball into the boundary at the extension of the center line opposite the recording table.

　　3. Foul against sportsmanship: A player is not legally trying to grab the ball directly within the scope stipulated by the rules, and the contact foul is a violation of sportsmanship. After the foul, the opponent will be awarded a free throw, and then the ball will be thrown into the line at the extension of the center line opposite the recording table. If a player fails to make a shot, he should be awarded two free throws; A foul on a player who is shooting a basket, such as a middle basket, should be scored and awarded a free throw. If you don’t hit the basket; Two or three free throws should be awarded.

　　Notes for watching the game:

　　As the host, every spectator who enters the stadium to watch the game should watch the game in a civilized way and forbid vulgar words and deeds. Specific attention should be paid to the following points:

　　(1) Visitors should enter and leave the venue in an orderly manner, and only bring soft-packed drinks into the stadium. Don’t sit on the steps of the passage when watching the game.

　　(2) The audience should not smoke after entering the gymnasium; Don’t walk around at will during the game; The mobile phone should be turned off or set in vibration and mute state. You can’t use the flash at will, especially when the players perform free throws.

　　(3) When the host introduces the players from both sides one by one, the audience should applaud each player. When the national flag of the participating countries is raised and the national anthem of the participating countries is played, the audience should stand up and pay attention.

　　(4) Don’t use language that infringes on the opposing team in the game, applaud the wonderful performances of both sides, and don’t use boos to influence the game and suppress opponents; Don’t use provocative body language.

　　Beijing, China, June 30 (Reporter Li Jinlei) On June 30, it was the last day of the annual calculation of comprehensive income of individual tax in 2019. If you don’t apply for tax refund, you should pay close attention to it, otherwise it will be wasted if you don’t get it. Those who have not paid the overdue tax should also pay close attention to it, otherwise they will face fines and late fees, which will also affect their personal credit.

　　Last day of annual tax settlement

　　The annual remittance of comprehensive income from individual tax in 2019 will be handled from March 1 to June 30, 2020. June 30th is the last day for annual settlement.

　　The so-called annual tax calculation is to "combine the annual income and calculate the tax on an annual basis", and then refund more and make up less. That is to say, the four incomes of wages and salaries, labor remuneration, manuscript remuneration and royalties are combined into "comprehensive income", and the individual tax is calculated on an annual basis.

　　The specific calculation formula is as follows:

　　In 2019, the tax payable or refundable is calculated = [(comprehensive income-60,000 yuan-special deductions such as "three insurances and one gold"-special additional deductions such as children’s education-other deductions determined according to law-donation) × applicable tax rate-quick deduction]-prepaid tax in 2019

　　Personal income tax rate table.

　　If you don’t get a tax refund, you’ll be wasted.

　　Who can get a tax refund? As long as you pay more taxes in advance because of insufficient deduction or undeclared deduction, taxpayers can apply for tax refund regardless of their income or the amount of tax refund.

　　For example, your comprehensive annual income in 2019 is less than 60,000 yuan, but your income is relatively high in a certain month, and you can get a tax refund if you pay a tax in advance.

　　For example, Xiao Ming received a salary of 10,000 yuan in January, and an individual paid "three insurances and one gold" of 2,000 yuan. Assuming there is no special additional deduction, he will pay a tax 90 yuan in advance; In other months, the monthly salary is 4000 yuan, and there is no need to pay taxes in advance. Throughout the year, because taxpayers’ annual income is less than 60,000 yuan, they don’t need to pay taxes, so they can apply for a refund of 90 yuan tax paid in advance.

　　For another example, if you didn’t declare to enjoy the six new special additional deductions (children’s education, continuing education, serious illness medical care, housing loan interest or housing rent, and supporting the elderly) in 2019, you may also get a tax refund after the declaration.

　　For example, Lao Wang’s monthly salary is 10,000 yuan, and the individual pays 2,000 yuan for "three insurances and one gold". According to the regulations, two children who go to primary school can enjoy a special additional deduction of 2,000 yuan per month (24,000 yuan for the whole year). However, because it was not reported in the prepayment link, the special additional deduction for children’s education was not deducted when calculating the tax, and the tax was paid in advance for 1080 yuan in the whole year. After filling in the relevant information in the annual settlement, it can supplement and deduct 24,000 yuan. After deduction, it should pay a tax of 360 yuan for the whole year, and it can apply for tax refund in 720 yuan according to regulations.

　　If you can get a tax refund, but you don’t declare it, the money will be wasted. Of course, it should be noted that the tax refund can be waived without any responsibility.

　　Screenshot of tax refund received by netizens in Weibo.

　　Failure to pay taxes will result in fines and late fees.

　　Although the tax refund can be waived, the tax payment cannot be waived. If you need to pay back taxes, you must make an annual settlement.

　　Who needs to pay taxes? That is to say, taxpayers whose comprehensive annual income exceeds 120,000 yuan and whose annual amount of supplementary tax is above 400 yuan need to pay supplementary tax.

　　There may be small partners who see that they have to pay taxes and want to ignore them. However, this kind of escape mentality is not desirable. If the tax is not paid on time, the consequences will be more serious. Don’t be fined, and you will have to pay a late fee, which will affect your personal credit.

　　State Taxation Administration of The People’s Republic of China said, if you should pay taxes, it is your obligation to handle the annual remittance. If you don’t pay the tax, you may face tax administrative punishment and record it in your personal tax credit file.

　　According to Article 62 of the Tax Administration Law, if a taxpayer fails to file tax returns and submit tax information within the prescribed time limit, the tax authorities shall order it to make corrections within a time limit and may impose a fine of less than 2,000 yuan; If the circumstances are serious, a fine of not less than 2,000 yuan but not more than 10,000 yuan may be imposed, and taxes shall be recovered and late fees shall be imposed. For late payment fees, from the date when the payment deadline is exceeded, five ten thousandths of the overdue tax will be charged on a daily basis.

　　Don’t trust the so-called "secret" of tax refund

　　In the process of annual tax settlement, some people are unwilling to see that others can get a tax refund, but their own tax refund amount is 0, so they make a bad idea, believe in the "tax refund strategy" and "tax refund tips" circulating on the Internet, and make a false declaration.

　　A case published by Zhejiang Taxation Bureau shows that taxpayer Zhang, according to the system trial calculation, should get a tax refund in 0 yuan, but he applied for a tax refund of 202.12 yuan by falsely reporting the special additional deduction for his serious illness medical treatment in 2019. In the daily monitoring, the tax department found that Zhang’s special additional deduction data was doubtful, and contacted Zhang for verification, requesting relevant retained information, but Zhang could not provide it. In the end, the tax department informed Zhang of the legal responsibility for not submitting the special additional deduction information truthfully, and advised Zhang to correct the declaration in time.

　　The tax department reminds that taxpayers need to declare the annual tax refund, and individuals should be responsible for the authenticity, accuracy and completeness of the declared information. Don’t believe in the so-called "tax refund tips" passed on the Internet and orally, so as to avoid false declarations or false declarations that violate the provisions of the tax law.

　　Have you settled the annual tax? Is it a tax refund or a tax payment? (End)

　

　Can chewing gum really open coconuts by rubbing it into a cone? (Video screenshot)

　　The scorching summer is a good time to drink coconut milk and eat coconut meat. Here is an interesting question: If you only have durian, rubber band and chewing gum at hand, which one do you think you can choose to open a coconut quickly?

　　You may not imagine that researchers will tell you that opening coconuts with chewing gum is one of the simplest and most feasible methods.

　　If you want to know the principle, you need to know all kinds of substances of non-Newtonian fluid and Newtonian fluid.

　　Inflatable fluid: eat soft but not hard

　　— — Chewing gum, starch solution, wet sand on the beach and concrete slurry belong to expansive fluids.

　　What is the correct posture to open coconuts with chewing gum?

　　First, knead a few pieces of chewing gum into a cone, then put the tip up and the bottom flat on the table, then hold the coconut to a certain height with your hands and hit it hard on the chewing gum. We will find that chewing gum will not be smashed flat, but will break a hole in the coconut. Repeat this several times, and the coconut can be broken.

　　Why on earth does chewing gum have such magical power? In fact, the principle is — — Non-newtonian fluid principle. There is a gum-based component in chewing gum, which belongs to the shear thickening fluid in non-Newtonian fluid. The viscosity of this fluid will increase under the action of a large external force, and the greater the external force, the greater the viscosity.

　　When the coconut hits the chewing gum at high speed, the viscosity of the chewing gum increases rapidly, and at this time it behaves as hard as a solid, thus piercing the hard shell of the coconut. Once the external force is withdrawn, it will return to the nature of liquid. If the external force is small and slow, it will behave like an ordinary liquid with fluidity. It’s really a soft guy.

　　When this fluid thickens, its volume will expand slightly, so the shear thickening fluid is also called expansive fluid. Starch solution, wet sand on the beach and concrete slurry all belong to this kind of fluid.

　　The change of viscosity of expansive fluid is related to its internal structure. That is, when shear thickening occurs, a certain structure is formed inside the fluid.

　　Expansive fluid is usually a multiphase mixture, such as wet sand on the beach, which is a mixture of sand and water. When there is no external force or the external force is very small, the irregular sand grains are densely packed, and water can be evenly filled in the gaps between the sand grains to play the role of lubricant. When someone steps on the sand, the original tightly packed structure is destroyed, and the "dislocation" between the sand grains will increase the volume; At the same time, the water is forced to move around, and the flow is disordered, and the resistance will increase, and the flow of sand is more difficult because of the loss of lubricant. Therefore, the sand surface infiltrated by seawater on the beach is easier to walk than dry sand, because this characteristic of wet sand will make our feet less prone to sink.

　　Bingham fluid: sometimes like a solid, sometimes like a liquid.

　　— — Toothpaste, facial cleanser and hand cream belong to Bingham fluid.

　　Since there is non-Newtonian fluid, there must be Newtonian fluid. Fluids whose shear stress and shear rate conform to Newtonian fluid formula belong to Newtonian fluid. Water and air are Newtonian fluids, and their shear stress is directly proportional to the shear rate.

　　Any fluid whose shear force and shear rate do not conform to Newtonian fluid formula is called non-Newtonian fluid. Besides expansive fluid, non-Newtonian fluid also includes pseudoplastic fluid and Bingham fluid. All kinds of sauces, oils, polymer solutions, mud in the kitchen, and even blood and cell fluids in organisms are non-Newtonian fluids.

　　The shear stress and shear rate of Bingham fluid are also linear, but unlike Newtonian fluid, it has a yield stress, and it will flow only when the external force is greater than the yield stress.

　　The most typical Bingham fluid is toothpaste. When there is no external force, it looks like a solid. Only when we squeeze toothpaste hard, it will "flow" out of the tube, and when it is squeezed into the toothbrush, it can still maintain a certain shape without "falling down". If you don’t squeeze it, it won’t come out even if you turn the toothpaste tube upside down.

　　Similarly, we can infer that things like facial cleanser and hand cream are also Bingham fluids. The paint used in buildings also needs to be designed as Bingham fluid. We require that it can flow when mixing and painting, and at the same time, it will not flow down from the wall because of gravity after being painted on the wall, that is to say, the yield stress of the paint should be greater than its own gravity.

　　Like expansive fluid, Bingham fluid is a multiphase mixture. It is generally believed that the fillers in Bingham fluid form a three-dimensional network structure, which has certain strength and can resist low external forces; When the external force is large enough, the three-dimensional structure is destroyed and the filler will flow with the solvent.

　　Pseudoplastic fluid: bullying the weak and fearing the hard.

　　— — Blood, magma, yogurt, tomato sauce and shampoo are pseudoplastic fluids.

　　If expansive fluid is soft and hard, then pseudoplastic fluid is a bully. Pseudo-plastic fluid shows the opposite properties to dilatant fluid, and its viscosity remains constant at low shear rate, but decreases with the increase of shear rate. That is to say, the greater the external force applied to it, the smaller the viscosity it shows. So it is also called shear thinning fluid.

　　Many polymer liquids belong to this kind of fluid. The viscosity of a fluid can be understood as the friction between molecules in the fluid, and the greater the friction, the greater the viscosity. Solute in polymer liquid is a kind of molecule with large molecular mass and long structure. Without external force, they are usually in a curled state, and the molecules may entangle and collide with each other, resulting in high friction. When there is an external force, the curled molecules will spread along the direction of shear force, and the molecules will be arranged in parallel, so the friction between them will be reduced, and thus the viscosity will be reduced.

　　Blood, magma, yogurt, tomato sauce and shampoo all belong to pseudoplastic fluids. When we stir yogurt or tomato sauce slowly, we will find it more difficult, but when we stir it quickly, it will be easier. In fact, this is the reason above.

　　Pseudoplastic fluid has another interesting phenomenon — — Kay effect. When a beam of pseudoplastic fluid with high viscosity hits a solid surface, the solid surface will bounce the liquid beam back upward.

　　Observing the experimental phenomenon carefully, it is not difficult to find that a layer of fluid always accumulates below the rebounding water flow. Combined with the properties of pseudoplastic fluid, the whole process should be like this: the rapidly falling liquid jet impacts the viscous fluid pile below, and the viscosity of the fluid surface becomes smaller due to the impact force, forming a dimple-shaped pit after the impact. At the same time, the surface with reduced viscosity acts as a lubricant, and finally the falling liquid jet is bounced out.
