阅读理解。 American boys and girls love to watch TV. Some children spend six hours a day in front of the TV set. Some children even watch TV for eight hours or more on Saturday. Many parents let their children watch TV only during certain (特定) hours. TV shows are like books or films. A child can learn bad things from some of them and good things from others. Some shows help children to understand the news from the world. Some programs (节目) show people and places from other countries or other times in history. With TV a child does not have to go to the zoo to see animals or to the sea to see a ship (轮船). Boys and girls can see a play or a basketball game at home.
