[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

Passage Four
You have been badly injured in a car accident. It is necessary to give you a blood transfusion because you lost a great deal of blood in the accident. However, special care must be taken in selecting new blood for you. If the blood is too different from your own, the transfusion could kill you.
There are four basic types of blood; A, B, AB and O. A simple test can indicate a person’s blood type. Everybody is born with one of these four types of blood. Blood type, like hair color and height, is inherited from parents.

A and B cannot receive AB, but AB may receive A or B.O can give to any other group, hence it is often called the universal donor. For the opposite reason, AB sometimes called the universal recipient. However, because so many reactions can occur in transfusions, patients usually receive only s

B. exactly the same type as yours
C. a mixture of salt, plasma and type O
