(D)

  Hotlines have become common in China．Some radio broadcasting stations use hotlines to encourage the listeners to take part in the talk shows．

  That’s a good idea．Yet，the fact is that some people do nothing but break the whole program．

  Some people know little about the topic under discussion．Sometimes they do not even know what the host(主持人)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 this 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 don’t care what the topic is，whether they themselves are interested in it or how silly they appear to be．

  I'm totally bored by those people．It’s necessary for the stations to improve the hotline programs. In my opinion，if a caller doesn’t know what is going on，the operator(接线员) should not let the caller take part in it．
