问题     Obviously television has both advantages and disadvantages.
    (78) In the first place, television is not only a convenient source of entertainment, but also a comparatively cheap one. With a TV set in the family people don’t have to pay for expensive seats at the theatre, the cinema, or the opera. All they have to do is to push a button or turn a knob, and they can see plays, films, operas and shows of every kind. Some people, however, think that this is where the danger lies. The television viewers need do nothing. He does not even have to use his legs if he has a remote control. He makes no choice and exercises, no judgment. He is completely passive and has everything presented to him without any effort on his part.
    Television, it is often said, keeps one informed about current events and the latest developments in science and politics. The most distant countries and the strangest customs are brought right into one’s sitting room. It could be argued that the radio performs this service as well; but on television everything is much more living, much more real. Yet here again there is a danger. The television screen itself has a terrible, almost physical charm for us. (79) We get so used to looking at the movements on it, so dependent on its pictures, that it begins to control our lives. People are often heard to say that their television sets have broken down and that they have suddenly found that they have far more time to do things and that they have actually begun to talk to each other again. It makes one think, doesn’t it?
    There are many other arguments for and against television. We must realize that television itself is neither good nor bad. It is the uses that it is put to that determine its value to society.
选项 A、To arouse the reader’s concern.
B、To introduce the theme of the whole passage.
C、To summarize the whole passage.
D、To state the primary uses of TV.
答案B
解析 本题考查的是考生对全文整体结构的把握。文章的第一段只有一句话： Obviously television has both advantages and disadvantages．“显然，电视既有优点又有缺点”，紧接着文章围绕着这一主题展开讨论。因此本段的作用是引出文章的主题。A项“为引起读者的关注”，跟文章总体结构不符；C项“为总结整篇文章”，由文章总体结构分析可知，总结部分在最后一段，也不符合题意。D项“为陈述电视的主要用途”显然是不正确的。所以只有B项最符合题意。
