Why is the gold content of China Cup the highest in Mathematical Olympics?
Olympic Mathematical Competition or Mathematical Olympics, or simply Olympics. 1934 and 1935, the Soviet union began to hold middle school mathematics competitions in Leningrad and Moscow, and named them Mathematical Olympics. 1959, the first international mathematical olympiad was held in Bucharest. As an international competition, the International Mathematical Olympiad was put forward by international mathematical education experts, which exceeded the level of compulsory education in various countries and was much more difficult than the college entrance examination. According to experts, only 5% of children with extraordinary intelligence are suitable for learning the Olympic Mathematics, and it is rare to reach the top of the international mathematical Olympics all the way. On August 2, 2065438+021day, Beijing took a number of measures to resolutely control the link between Olympic math scores and further studies. Olympic Mathematics has a certain effect on teenagers' mental exercise, which can exercise their thinking and logic, and it plays a more profound role for students than ordinary mathematics. The "National Primary School Mathematics Olympics" (founded in 199 1) is a popular activity, which is divided into preliminary competition (March every year) and summer camp (summer every year). The "National Junior Middle School Mathematics League" (founded in 1984) is held in April every year in the form of "taking turns to host", which is divided into first instance and second instance. The "National Senior High School Mathematics League" (founded in 198 1) is held in the same way as the junior high school league, which is divided into initial test and retest. About 90 students who have achieved excellent results in this competition are eligible to participate in the "China Mathematical Olympics (CMO) and the National Winter Camp for Middle School Students" hosted by chinese mathematical society (every year 1 month). In the competition, it is stipulated that the host country of the editor's (1) annual IMO will be held by the participating countries (or regions) in turn, and the required funds will be borne by the host country. The whole activity will be hosted by the host country and the examiners' committee composed of national leaders. The exam questions and answers will be provided by the participating countries, and each country will provide 3-5 questions (or not). Instead, the host country will set up a selection committee to evaluate the examination questions provided by various countries. Mainly consider whether the test questions are repeated before, and classify the test questions according to algebra, number theory, geometry, combinatorial mathematics, combinatorial geometry and so on. , determine the difficulty of the test questions (A, B, C), and select about 30 questions. If there are new answers to these questions, it is also required to provide answers other than the original answers and translate them into English for the examiner to choose. (2) Each team shall organize a team with no more than 8 members, including no more than 6 members (students from middle schools or schools at the same level), 1 team leader and deputy team leader. The exam will be held in two days, with 3 questions each, 4.5 hours each and 7 points each, so the highest score of each player is 42 points. (3) The official languages of IMO are English, French, German and Russian, and participating countries need about 26 languages. At that time, the team leaders will translate the test papers into the national language and get the approval of the coordination Committee. The marking is first judged by leaders and deputy leaders of various countries, and then negotiated with the Coordination Committee (each coordinator is responsible for marking a test question). If there are differences, the examiners' committee will arbitrate, and the negotiation will be conducted in a trusting and friendly atmosphere. (4) The number of winners of IMO accounts for about half of the participants, and the winners of the first, second and third prizes are awarded in order of their scores, with an average ratio of 1:2:3. In addition, the examiner's committee can award special prizes to students who have made a very beautiful (meaning simple, ingenious and original) or mathematically meaningful answer to a question. In order to avoid the interruption of 1980 again, IMO set up a special committee (some translated as venue committee) to determine the host of each session. According to IMO regulations, the host of each session must send an invitation to all the participating countries in the previous session, and the new participating countries must show their willingness to participate in the competition to the host, and then the host will send an invitation. Among the countries outside Eastern Europe, Finland was the first to join (1965 7th), and France, Britain, Italy, Sweden and the Netherlands joined in succession in 1960s. 1974, the United States and Vietnam joined. Since then, the number of participating countries has increased year by year, covering Europe, the United States, Asia, Africa and Oceania, and IMO has become a truly global mathematics competition. 1988 In the 29th session, IMO set up an honorary prize for the first time at the suggestion of Hong Kong, and awarded it to those players who got full marks in at least one question although they didn't win gold, silver or bronze medals. This measure greatly mobilized the enthusiasm of all participating countries and their players. The spirit of IMO is the Olympic spirit: "The important thing is not to win, but to participate." Accordingly, since the 24th 1983, although each team (6 people) has calculated their total scores and knows how many people rank according to the order of total scores, the organizing committee does not award prizes to the team winners, because IMO is only an individual competition, not a team competition. 198 1 22nd, the United States is the host of IMO. Greitzer, chairman of the American Mathematical Olympiad Committee, sent a letter inviting China to participate, and chinese mathematical society wrote back and agreed to participate. Later, he failed to make the trip and only sent visiting scholars from the United States as observers. 1984, at the first meeting of chinese mathematical society's popularization work held in Ningbo, it was decided to send two contestants to participate in the 26th IMO in 1985, so as to learn about the situation and accumulate experience. Due to the hasty selection time, only 1 outstanding students from Beijing and Shanghai were arranged to participate. Results 1 person won the third prize, and their average score with Israel was 17, while their total score was 32. Starting from 1986, China sent six players to participate in the competition. The brilliant achievements of China athletes have greatly stimulated the enthusiasm of millions of middle school students to learn scientific and cultural knowledge, and also greatly enhanced the sense of national honor of the people of China. If it is a national competition, we must achieve good results in this province, that is, the provincial mathematics competition must pass the preliminary and semi-finals, enter the provincial team, and have the opportunity to participate in the national competition. Mathematics, it is estimated that the provincial division must be the first prize. Please refer to previous years' information for details. In short, it is recommended by the province, and it needs excellent math scores. Of course, it is not enough just to learn the knowledge in class. You should buy some books on Olympic Mathematics to study, and it would be better if there were training classes.
