Most children like watching TV. It’s very interesting. By watching TV they can see and learn a lot and know many things about their country and the world. Of course ,they can also learn over the radio. But they can learn better and more easily on TV. Why? Because they can hear and watch at the same time. But they can’t see anything over the radio.

1. C 细节题。从But a few children watch TV every night. They go to bed very late可知答案为C。
