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