Not only adults but also teenagers have problems in their life. Here  a survey showing the main problems of teenagers.

    They feel stressed  they have too many exams （take）. And parents usually send them to different classes at weekends. As a result, so many of  almost become bookworms（书虫）. On holidays, they could hardly have their own time to do what they are interested . Now more and more teenagers are getting short-sighted. They often read in bed or keep （read）for a long time without having a rest. Some of them arc crazy about（play）computer games. Some spend too much time （watch） TV. Another 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 （deal）with the problem. They should make a plan for study and hobbies and find time to relax as much as possible.
