There are many reasons why schools offer swimming courses. Some are to improve students' physical quality and health level, and some are to meet students' interests and needs. In China, more and more schools begin to offer swimming courses. This is because the government of China is promoting the national fitness campaign, and swimming is a sport that is very suitable for public participation. In addition, some schools have set up swimming courses to meet the needs of parents, because they hope their children can learn to swim.
