A、It is time-consuming. B、It provides harmful programs. C、Its viewers are passive to the presented programs. D、Its entertainment

Television is now playing a very important role in our lives. But television, like other things, has both advantages and disadvantages.
    First, television is not only a convenient source of entertainment, but a comparatively cheap one. It’ s convenient as well as cheap to sit comfortably at home, with almost unlimited entertainment available. Some people, however, maintain that this is precisely where the danger lies. A television viewer takes no originality. He makes no choice and exercises no judgment. He is passive and has everything presented to him without any effort on his part.
    Television, it is often said, keeps one informed about current events, allows one to follow the latest developments in science and politics, and offers an endless series of programs that are both instructive and entertaining. Yet here again there is a danger. We get so used to looking at it, so dependent on Its moving pictures, that it begins to control our lives.
    There are many other arguments for and against television. Television in itself is neither good nor bad. It is the uses to which it is put that determine its value to society.
