Boys and girls love to watch TV. Some children spend six hours a day in school and four to six in front of the TV set. Some children even watch TV for eight or more hours on Saturday. TV programmes are like books and films. A child can learn bad things from some of them and good things from others. Some programmes help children know the news from the other parts of the world. Some programmes show people and places from other countries or other times（時代）in history. With TV, a child doesn’t need to go to the zoo to see animals or to the sea to see a ship. Boys and girls can see a film, a play or a basketball match at home. Some programmes can teach children how to cook or how to use tools. It’s interesting to watch TV, but it is also interesting to read a book or to visit friends.
