二、阅读理解（共3道试题，共60分。）
1. Nuclear power’s danger to health, safety, and even life itself can be summed up in one word: radiation.
Nuclear radiation has a certain mystery about it, partly because it cannot be detected by human senses. It can’t be seen or heard, or touched or tasted, even though it may be all around us. There are other things like that. For example, radio waves are all around us but we can’t detect them, sense them, without a radio receiver. Similarly, we can’t sense radioactivity without a radiation detector. But unlike common radio waves, nuclear radiation is not harmless to human beings and other living things.
At very high levels, radiation can kill an animal or human being outright by killing masses of cells in vital organs. But even the lowest level of radiation can do serious damage. There is no level of radiation that is completely safe. If the radiation does not hit anything important, the damage may not be significant. This is the case when only a few cells are hit, and if they are killed outright. Your body will replace the dead cells with healthy ones. But if the few cells are only damaged, and if they reproduce themselves, you may be in trouble. They reproduce themselves in a deformed way. They can grow into cancer. Sometimes this does not show up for many years.
This is another reason for some of the mystery about nuclear radiation. Serious damage can be done without the victim being aware at the time that damage has occurred. A person can be irradiated and feel fine, then die of cancer five, ten, or twenty years later as a result. Or a child can be born weak or liable to serious illness as result of radiation absorbed by its grandparents.
Radiation can hurt us. We must know the truth.

A. nuclear mystery

2. Though it is mere 1 to 3 percent of the population, the upper class possesses atleast 25 percent of the nation's wealth. This class has two segments: upper-upper and lower-upper. Basically, the upper-upper class is the “old rich”—families that have been wealthy for several generations and aristocracy of birth and wealth. Their names are in the Social Register, a listing of acceptable members ofhigh society. A few are known across the nation, such as the Rockfellers, Roosevelts, and Vanderbilts. Most are not visible to the general public. They live in grand seclusion(深居简出)，drawing their income from the investment of their inherited wealth. In contrast, the lower upper class is the “new rich”. Although they may be wealthier than some of the old rich, the new rich have hustled(急于做) to make their money like everybody else beneath their class. Thus their prestige is generally lower than that of the old rich, who have not found it necessary to lift a finger to make their money, and who tend to look down upon the new rich.
However its wealth is acquired, the upper class is very, very rich. They have enough money and leisure time to cultivate an interest in the arts and to collect rare books, painting, and sculpture. They generally live in exclusive areas, belong to exclusive social clubs, communicate with each other, and marry their own kind—all of which keeps them so distant from the masses that they have been called the out-of-sight class. More than any other class, they tend to be conscious of being members of a class. They also command an enormous amount of power and influence here and abroad, as they hold many top government positions, run the Council on Foreign Relations, and control multinational corporations. Their actions affect the lives of millions.
1).All the following statements are true except that ______.
A. the upper-upper class is of aristocratic origins.

3. As the pace of life continues to increase, we are fast losing the art of relaxation. Once you are in the habit of rushing through life, being on the go from morning till night, it is hard to slow down. But relaxation is essential for a healthy mind and body.
Stress is a natural part of everyday life and there is no way to avoid it. In fact, it is not the bad thing it is often supposed to be. A certain amount of stress is vital to provide motivation and give purpose to life. It is only when the stress gets out of control that it can lead to poor performance and ill health.
The amount of stress a person can withstand depends very much on the individual. Some people are not afraid of stress, and such characters are obviously prime material for managerial responsibilities. Others lose heart at the first signs of unusual difficulties. When exposed to stress, in whatever form, we react both chemically and physically. In fact we make choice between "fight" and "flight" and in more primitive days the choice made the difference between life and death. The crises we meet today are unlikely to be so extreme, but however little the stress, it involves the same response. It is when such a reaction lasts long, through continued exposure to stress, that health becomes endangered. Such serious conditions as high blood pressure and heart disease have established links with stress. Since we cannot remove stress from our lives it would be unwise to do so even if we could), we need to find ways to deal with it.
1).People are finding less and less time for relaxing themselves because___
A. they do not know how to enjoy themselves
B. they do not believe that relaxation is important for health
C. they are traveling fast all the time
D. they are becoming busier with their work

满分：4分
4).In Paragraph 3, "such a reaction" refers back to____
A. "making a choice between 'flight' and 'fight'"
B. "reaction to stress both chemically and physically"
C. "responding to crises quickly"
