[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

[简答题]
61. While there are almost as many definitions of history as there are historians, modern practice most closely conforms to one that sees history as the attempt to recreate and explain the significant e vents of the past. Caught in the web of its own time and place, each generation of historians deter mines anew what is significant for it in the past. In this search the evidence found is always incomplete and scattered; it is also frequently partial or partisan. The irony of the historian’ s craft is that its practitioners always know that their efforts are but contributions to an unending process。 62. Interest in historical methods has arisen less through external challenge to the validity of history as an intellectual discipline and more from internal quarrels among historians themselves. While history once revered its affinity to literature and philosophy, the emerging social sciences seemed to afford greater opportunities for asking new questions and prov

There is nothing unusual about a single language dying. Communities have come and gone throughout history, and with them their language. But what is happening today is extraordinary, judged by the standards of the past. It is language extinction on a large scale.
