Children love to watch TV. Many children stay at school for eight hours a day and sit in front of the TV for four or six hours a day. Some children watch TV for eight hours or more on Saturdays and Sundays. It's bad for their eyes.
TV programmes are like books. Some can help children know the news from different places. With the TV，a child doesn't have to go to the zoo to see animals or go to the sea to see a ship. Children can see a play（戏剧），a film or a race（赛跑）at home.
But some programmes are not good for children. Parents should help them find useful and interesting things to do.
