The National Aquatics Center, also known as the Water Cube, is located in Beijing Olympic Park. It is the main swimming pool built by Beijing for the 2008 Summer Olympic Games, and it is also one of the landmark buildings of the 2008 Beijing Olympic Games. Its design scheme is the "Water Cube" ([H2O]3) scheme produced by the global design competition. Construction started on February 24, 2003 and is expected to be completed and accepted in June 2007. It and the National Stadium (commonly known as the Bird's Nest) are located on both sides of the northern end of Beijing's central axis, which together form a relatively complete image of Beijing's historical and cultural city. The planned construction land of the National Swimming Center is 62,950 square meters, with a total construction area of 65,000-80,000 square meters, of which the underground construction area is not less than15,000 square meters, and the length, width and height are177m× 30m respectively. Uses During the 2008 Olympic Games, the National Aquatics Center will host swimming, diving, synchronized swimming and swimming competitions. It can accommodate spectators 17000 seats, including 6000 permanent seats, and 1 1000 temporary seats will be added during the Olympic Games (removed after the Games). After the Olympic Games, it will be built into an international advanced center integrating swimming, sports, fitness and leisure. Fuwa has five mascots. They are: Fuwa Huanhuan, Fuwa Beibei, Fuwa Yingying, Fuwa Jingjing and Fuwa Nini. These lovely Fuwa add up to the meaning of "Welcome to Beijing". Their prototype comes from fish, panda, Olympic flame, Tibetan antelope and Jin Yan. Jingjing is a naive giant panda, and wherever she goes, she will bring joy to people. As the national treasure of China, the giant panda is deeply loved by people all over the world. Jingjing comes from the vast forest, symbolizing the harmony between man and nature. His head decoration originated from the lotus petal shape on Song porcelain. Jingjing is simple, honest, optimistic and full of strength, representing the black part of the Olympic rings. Huanhuan is Fuwa's eldest brother. He is a fire doll, symbolizing the Olympic flame. Huanhuan is the embodiment of sports passion, which spreads passion to all parts of the world and conveys the Olympic spirit faster, higher and stronger. Everywhere Huanhuan went, Beijing 2008 was full of enthusiasm for the world. Huanhuan headdress originated from the flame patterns in Dunhuang murals. He is extroverted and unrestrained, familiar with all kinds of ball games, representing the red ring of the Olympic rings. Yingying is a clever, agile and flying Tibetan antelope. He comes from the vast western land of China and sends his best wishes to the world. Yingying is a unique protected animal in the Qinghai-Tibet Plateau and a demonstration of the Green Olympics. Yingying's head decoration combines the decorative styles of the Qinghai-Tibet Plateau, Xinjiang and other western regions. He is agile and an excellent track and field athlete, representing the yellow ring in the Olympic rings. Nini is from the sky. She is a swallow spreading her wings and flying. Her modeling creativity comes from the traditional Shayan kite in Beijing. Yan also stands for Yanjing (the title of ancient Beijing). Nini brings spring and joy to people. Wherever she flies, she spreads good wishes of "good luck". Naive, cheerful and agile Nini will make her debut in gymnastics competition. She represents the green ring in the Olympic rings. Mathematical Problems in the Olympic Games The emblem of Beijing's bid to host the Olympic Games, which consists of the five Olympic rings, looks like a "Chinese knot" in China's traditional folk arts and crafts, and also looks like a human figure beating Tai Ji Chuan. The pattern is flowing, harmonious, vivid and dynamic. Beijing's Olympic emblem, seemingly printed but not printed, looks like "Beijing" rather than "Beijing", elegant and full of tension, implying dancing Beijing; China Seal-This is1300 million China people's commitment to the whole world. "New Beijing, Great Olympics" is the slogan of Beijing's Olympic bid. "Green Olympics, High-tech Olympics, People's Olympics" is the theme of Beijing Olympic Games. I know that many games need to be timed. For example, in swimming competition, we can see the knowledge of hours, minutes and seconds in mathematics. The track of track and field competition is also very knowledgeable. For example, when starting at 400 meters, the athletes are not at the same starting line, so there is knowledge of the circle in mathematics. Some games have scores, such as basketball games, which are comparative knowledge in mathematics. There will be many numbers in the competition. For example, the number of athletes is an integer and the number of shots will be accurate to the decimal point. In addition, the finals of 1/8 and 1/4 that we often hear are all scores. There are many names in the stadium. For example, 200 meters, 100 kg and so on. The results of some competitions need to be averaged, so there is both knowledge of calculation and knowledge of averaging. In fact, the competition system of some competitions is also very knowledgeable. The round robin is over, and the knockout is over, which will involve the knowledge of combination in mathematics. In the past year, most students were able to keep pace, but a few students quickly adapted to junior high school teaching through their own efforts and made great progress. Some students can't adapt to junior high school teaching at once, and their self-confidence drops, which widens the gap with other students. With the further deepening of learning, this gap will continue to increase under the condition of letting nature take its course. We give students some reference and guidance suggestions on how to learn math knowledge well in senior two. First of all, you should be interested in learning mathematics. More than 2,000 years ago, Confucius said, "Knowing is not as good as being kind, and being kind is not as good as being happy." The "good" and "happy" here are willing to learn, love learning and have interest in learning. Einstein, a world-famous great scientist and founder of the theory of relativity, also said: "In school and life, the most important motivation for work is the fun at work." The fun of learning lies in the initiative and enthusiasm of learning. We often see some students burying themselves in reading and thinking for a long time in order to find a mathematical concept. In order to solve a math problem, forget all about eating and sleeping. First of all, because they are interested in mathematics learning and research, it is hard to imagine that they are not interested in mathematics. People who have a headache when they see math problems can learn math well. To cultivate their interest in learning mathematics, we must first understand the importance of learning mathematics. Mathematics, known as the queen of science, is an essential tool for learning and applying scientific knowledge. It can be said that without mathematics, it is impossible to learn other subjects well; Secondly, we should have the spirit of learning and the tenacity to learn well. In the process of in-depth study, we can understand the mystery of mathematics and the joy of learning mathematics to succeed. If you persist for a long time, you will naturally have a strong interest in mathematics and arouse your high consciousness and enthusiasm in learning mathematics well. With the interest and enthusiasm in learning mathematics, we should learn mathematics well, pay attention to learning methods and develop good study habits. Knowledge is the foundation of ability, so we should learn basic knowledge well. The learning of basic mathematics knowledge includes three aspects: concept learning, theorem and formula learning and problem-solving learning. To learn a mathematical concept, we should be good at grasping its essential attribute, which is different from other concepts; To learn theorem formulas, we should firmly grasp the internal relationship of theorem directions, grasp the applicable scope and types of theorem formulas, and skillfully use these theorem formulas. Solving mathematical problems is actually solving contradictions on the basis of mastering concepts and theorems and formulas, and completing the transformation from "unknown" to "known". We should focus on learning various transformation methods and cultivate transformation ability. In short, in the study of basic mathematics knowledge, we should pay attention to the overall nature of knowledge, understand its laws and essence, form a closely related overall understanding system, and promote the mutual migration and transformation among various forms. At the same time, we should also pay attention to people's ways, means and strategies to solve problems in the process of knowledge formation, and take mathematical ideas and methods as guidance everywhere, which is what we want to learn most when learning knowledge.
