       Not only adults but also teenagers have problems in their life. Here is a survey showing the main   1   
of teenagers.
       They feel   2   because they have too much homework to do both at school and at home. They have
lots of exams   3   . And parents usually send them to different classes at weekends. They don't have their   4   time to do what they are   5   in. Now more and more teenagers are getting short-sighted(近视).
They often read in bed or keep   6   for a long time   7   having a rest.  Some of them are crazy about
  8_ 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   9_exercise.
       I think teenagers should think of ways to   10   with the problems. They should make a plan for study and hobbies and find time to relax as much as possible.
