Writing 3_ Watching TV is harmful to children or not.

TV is the most popular entertainment tool all over the world. It has both many advantages and disadvantages to us, especially to children. There are some arguments around this problem that watching TV is harmful to children or not. In my opinion,over watching TV is not only harmful to children's health but also their studying.

Firstly, watching TV too much makes bad effects on children's health. Children sit many hours in front of TV means they do not do any other activities; it makes children lazy and do not want to do exercises too so they are easy to get obesity. It also affects to thier eyes. For example, their eyes will be affected by myopia, even serious myopia. Moreover, over watching TV decrease children's creative thinking because they do not attend outdoor activities. Besides, some programs on TV such as horror film, violent films...make them get nightmare or be obsessed by these. IN short, watching TV much is not good for children's physical and mental health.

Secondly, children addicting to watching TV have bad result of studying. If they spend much time to watch TV, they will have less time for studying. It also makes children become lazy. They just want to watch TV all the time and do not care about their lesson. As a result, they will get bad result for studying. Some people think that children can learn some useful things from TV such as discover channel, scientific programs. It also helps them to relax. However, these programs usually make them bored so they do not want to watch any more and change to other film or entertainment programs. Furthermore, parents are so busy, they can not control which channel their children choose or the time they sit in front of TV. It leads children to getting addicted to watching TV and do not concentrate on studying.

To brief, children should not watch Tv too much because of above reasons. It is really not good to children. To reduce these bad effects, parents should control more strictly what their children watch on TV.
