Most children like watching TV because it is interesting. Through TV, they can see and learn a lot and learn about their own country and things around the world. Of course, they can also learn about this by listening to the radio. But with TV, they can learn better and easier. Why? Because they can listen and watch. They can't see anything on the radio. Television broadens children's horizons and helps them think. They learned knowledge and methods of doing things. They may find that the world is smaller than before. Many children only watch TV on Saturday and Sunday nights. They are always busy with their homework. But some children watch TV every night and can't have a good rest. What about you, my young friends?
