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。

2. B 此题需要注意同义词的转换。文章说But they can’t see anything over the radio，over the radio即on the radio通过广播，故选B。

3. A 细节题，我们可以从TV helps to open children’s eyes及It helps to open their minds , too可知有两个方面的作用：开阔眼界和思维，选A。

4. C 我们首选找到这句话，在后面就有这个原因的分析：They are always busy with their lessons(他们总是忙于功课)，故选C。

5. D 此题也是细节理解题。原文选说明事实再问为什么：But they can learn better and more easily on TV. Why?，后面再作答：Because they can hear and watch at the same time，故选D。
