Hotlines have now become very popular in China. Many radio stations are using hotlines to get more 41 to take part in the talks that people are very interested in.
That’s a good idea, but there is also a 42 : some people just pick up the phones and do 43 to break this program(节目). They know 44 about the topic(话题), and they haven’t got any new idea about what the host (主持人) is 45 about. So they have to ask a few questions 46 they can join(参加) in the talk. 47 the host has to explain and 48 his questions from the 49 so that the phone caller can 50 his own ideas---how 51 it is! This is just a waste(浪费) of 52 !
It seems that some of the people phone the hotline just for 53 , not for giving his own ideas. He just wants his own voice heard on the radio, and the next day some of his friends may say that I heard you on the 54 talking quite a long time, and the caller would find himself very much pleased. So remember that don’t join in the hotline talk 55 you have really got nothing new to say!
