Good morning, teachers and students. Today, the topic of our national speech is "strengthening physique and shaping personality". Students, last week's light rain made the temperature drop obviously, and winter has indeed come to us. At the same time, we also found that the number of students with colds and fever in the classroom increased significantly during this period. This is the result that our bodies can't resist the cold. Winter is a good time to exercise. We can take an active part in physical exercise and strengthen our physique. 1000 years ago, an ancient Greek proverb was engraved on the rock: "If you want to be smart, run; If you want to be strong, run; If you want to be healthy, run. " This adage reveals a philosophy to us-everyone can get a strong body, so you must actively exercise and insist on physical exercise. Students, I believe that each of you has your own ideals and wants to be a scientist, a doctor, a soldier, a teacher and so on. But while realizing these ideals, you must have an important premise, that is, you must have a healthy and strong body. Without a sound body, it is impossible to create and invent when you become a scientist. When you become a doctor, you can't treat patients, but you have to be taken care of by others. Therefore, having a healthy body has a lot to do with our present study and building our motherland when we grow up. We should start from an early age and actively exercise to lay a solid foundation for future work and study. Some students may say, I like physical exercise very much, but I have no time to exercise! With so much homework, we have to sacrifice physical exercise. As the saying goes: sharpening a knife does not miss the woodcutter. Although it will take a little time for us to take physical exercise now, what we will get will be the enhancement of physical fitness and the improvement of learning efficiency, which will not only ensure your healthy learning needs now, but also ensure your lifelong needs for work and life in the future. So, how to do physical exercise scientifically? Please remember three points: first, physical exercise should be gradual. This is what the saying goes, take your time, you can't eat a big fat man in one bite. To participate in physical exercise, it is necessary to do the exercise from small to large, the exercise intensity from weak to strong, and the technical difficulty from easy to difficult. With the extension of exercise time, you can gradually increase the amount and intensity of exercise. Second, physical exercise should be comprehensive. Insisting on comprehensiveness means that the exercise programs should be varied, so that all parts of your body can get balanced exercise and development. The content of physical exercise should be rich and colorful, such as running, skipping rope, kicking shuttlecock, playing badminton and table tennis. Third, physical exercise should be persistent. The fitness effect of physical exercise can't be achieved once or twice a day. It takes a long time to keep exercising to get results. For example, doing exercise for half an hour every day and doing physical education class in every class are all effective methods. Students, have you remembered all the three points the teacher just said? Every year1February is the winter fitness month of our school. Students can do physical exercise by kicking shuttlecock and skipping rope between classes and after school. The school and the brigade will hold a school-wide tug-of-war competition in late February of/kloc-0. Dear students: Youth is an era with lofty aspirations; Youth is an era of pursuing Excellence and wisdom; Youth is an era of forging a strong body. Let's meet more intense challenges and difficulties with healthier bodies. Let's exercise together for the soaring of the Chinese nation and your health. Finally, I wish all teachers and students a healthy and strong body.
