Television is now playing a very important part in our life. But television, like many     11    things, has both advantages and disadvantages. Do the 12      outweigh (比…更重要) the latter?

In the first place, television is not only a convenient source of entertainment, but also     13       comparatively cheap one. For a family of four, for example, it is  14      as well as cheaper to sit comfortably at home, with almost unlimited entertainment available, than to go out in search of amusement elsewhere.

All they have to do is   15      (press) a button, and they can see plays, films, operas, and shows of every kind, not to mention the latest    16     (excite) football match. Some people,    17      maintain that this is precisely    18     the danger lies. The television viewer makes no choice and exercises no judgment. He is completely passive and has everything     19  (present) to    20    without any effort on his part.
