阅读理解。      Not only adults but also teenagers have problems in their life. Here is a survey showing the main problems
of teenagers.
     They feel stressed because they have too much homework to do both at school and at home. They have
lots of exams to take. And parents usually send them to different classes at weekends. They don"t have their
own time to do what they are interested in. Now more and more teenagers are getting short-sighted (近视).
They often read in bed or keep reading for a long time without having a rest. Some of them are crazy about
playing computer games. Some spend too much time watching 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 to deal with the problems. They should make a plan for study and
hobbies and find time to relax as much as possible.                                                            Information Card
