Not only adults but also teenagers have problems in their life. Here is a survey showing the main problems of . They feel stressed because they have homework to do both at school and at home. They have lots of exams . And parents usually send them different classes at weekends. As a result, so many of them almost become bookworms(书虫). On holidays, they could hardly have time to do what they are interested in. Now more and more teenagers short-sighted. They often read in bed or keep for a long time without having a rest. Some of them are crazy about playing computer games. Some too much watching TV. serious problem among teenagers is that many of them are becoming fat. They eat too much junk food, but they take little exercise. I think teenagers should think of ways on how to the problem. They should make a plan for study and hobbies and find time to relax as much as possible.
