题目内容：

D

In China, some radio broadcasting stations use hotlines to encourage listeners to take part in the talk shows.

That is a good idea. Yes, the fact is that some people do nothing but break the whole programme.

Some people know little about the topic under discussion. Sometimes they do not even know what the host is talking about. So the host has to tell the caller what the show is about. Usually the caller will ask a few questions which express his hope and show his ignorance(无知). Then the host has to answer and explain ---how silly it is! It wastes a lot of time.

It seems that some people phone the hotlines for fun. They just want to let the listeners hear them. They do not care what the topic is, whether they themselves are interested in the topic or how silly they appear to be.

It is necessary for radio stations to improve the hotline programmes. In my opinion, if a caller does not know what is going on, the operator should not let the caller take part in it.
