[简答题] Most Americans spend far more of their leisure time with the mass media than in any other occupation. In addition, most of us hear, see, or read some of the media while engaged in other activities. Thus an extremely large number of our waking hours are spent with the mass media. Of all the media, television is clearly dominant, with newspapers a close second, at least as a source of news and other information. Our exposure to all media is important, however, because all of them contribute materials for the construction of that world in our heads. For most people, increased use of one medium does not decrease use of another. In fact, in certain cases, and especially for certain purposes, the more one uses one medium, the more likely one is to use others. There are various factors that can cause you to expose yourself to the media selectively, avoiding much of the material with which you disagree. Some of that selective exposure is probably due to the psychological pressure you

Most of us lead unhealthy lives; we spend far too much time sitting down. If in addition we are careless about our diets, our bodies soon become flabby and our systems sluggish. There are some aspects of our unhealthy lives that we cannot avoid. I am thinking of such features of modern urban life as pollution, noise, rushed meals and stress. But keeping fit is a way to minimise the effects of these evils. The usual suggestion to a person who is looking for a way to keep fit is to take up some sport or other. While it is true that every weekend you will find people playing football and hockey in the local park, they are outnumbered a hundred to one by the people who are simply watching them.
For those who do not particularly enjoy competitive sports—and it is especially difficult to do so if you are no good at them—there are such solitary activities as cycling, walking, jogging and swimming. What often happens though is that you do them in such a leisurely way,
A. don’t do them very often
B. don’t do them vigorously enough
C. find it hard to get out of our armchairs
D. don’t find them interesting
