这是一个辩论的反方题目，一辩，字数300左右！

There is just as much bad material as good material on TV. Unless a parent monitors what the child watches, it is very easy for them to see shows with profanity, violence, sex, and other inappropriate material. It's hard to filter these programs out, as they become prevalent. For adolescents, most of the "teen dramas” on television are unrealistic such as Gossip Girl which is very famous among the young generation, although they might be entertaining and its part of adolescence to discuss these shows with friends. Watching TV makes it harder for kids to want to go out and exercise, although computer does that too.
