下面有3篇短文，每篇短文后有5道题，每道题后面有4个选项。第一篇 A Thirsty World The world is not only hungry; it is also thirsty for water. This seems strange to you, since nearly 75% of the earth’s surface is covered with water. But about 97% of this huge amount is from sea water, or salt water. Man can only drink and use the other 3% — the fresh water that comes from rivers, lakes, underground, and other sources. And we cannot even use all of that, because some of it is in the form of iceberg (冰山) and glaciers (冰串). Even worse, some of it has been polluted. At the moment, this small amount of fresh water is still enough for us. However, our need for water is increasing rapidly. Only if we take steps to deal with this problem now can we avoid a severe worldwide water shortage later on. A limited water supply would have a bad effect onagriculture and industry. In addition to stopping wasting our precious water, one useful step we should take is to develop ways of reusing it. Experiments have already been done in this field, but only on a small scale. Today, in most large cities tanks, water is used only once and it eventually returns to the sea or runs into underground storage tanks. But it is possible to pipe water that has been used to a purifying (净化) plant. There it can be filtered (过滤) and treated with chemicals so that it can be used again just as it were fresh from a spring. But even if every large city purified and reused its water, we still would not have enough. Where could we turn next To the oceans! All we’d have to do to make use of the vast amount of sea-water is — remove the salt. This salt-removing process is already in use in many parts of the wodd. What percentage of the earth’s water can man actually use at present

第二篇 Stress Level Tied to Education Level People with less education suffer fewer stressful days, according to a report in the current issue of the Journal of Health and Social Behavior. However, the study also found that when less-educated people did suffer stress it was more severe and had a larger impact on their health. From this, researchers have concluded that the day-to-day factors that cause stress are not random. Where you are in society determines the kinds of problems that you have each day, and howwell you will cope with them. The research team interviewed a national sample of 1,031 adults daily for eight days about their stress level and health. People without a high school diploma reported stress on 30 percent of the study days, people with a high school degree reported stress 38 percent of the time, and people with college degrees reported stress 44 percent of the time. "Less advantaged people are less healthy on a daily basis and are more likely to have downward tums in their health." lead researcher Dr. Joseph Grzywacz,of Wake Forest University Baptist Medical Center, said in a prepared statement. "The downward tums in health were connected with daily stressors. and the effect of daily stressors on their health is much more devastating for the less advantaged." Grzywacz suggested follow-up research to determine why less-educated people report fewer days of stress when it is known their stress is more acute and chronic. "If something happens every day, maybe it’s not seen as a stressor" Grzywacz says. "Maybe it is just life." stressor n.紧张刺激物 devastating adj.毁灭性的 follow-up n. (对病人的)随访 Stress level is closely related to ______.
