第1题:
If you are like most people, your intelligence varies from season to season. You are probably a lot sharper in the spring than you are at any other time of the year. A well-known scientist, Ellsworth Huntington (1876-1937), concluded from other men's work and his own among people in different climates that climate and temperature have a definite effect on our mental abilities. He found that cool weather is much more favorable for creative thinking than summer heat. This does not mean that all people are less intelligent in the summer than they are during the rest of the year. It does mean, however, that the mental abilities of large numbers of people tend to be lowest in the summer.
Spring appears to be the best period of the year for thinking. One reason may be that in the spring man's mental abilities are affected by the same factors that bring about great changes in all nature. Fall is the next-best season, then winter. As for summer, it seems to be a good time to take a long vacation from thinking!
1). Huntington based his conclusions on ___________.
A. work with people in different climates
B. records of temperature changes
C. records of change in his own intelligence
D. all of the above
2). Ellsworth Huntington decided that climate and temperature have _________.
A. a great effect on everyone's intelligence
B. no effect on people's intelligence
C. effect on only a few people's intelligence
D. some effect on most people's intelligence
3). One possible reason why spring is the best season for thinking is that ___________.
A. there are some things making all nature different from before
B. it is neither too warm nor too cold
C. it is more natural for the development of mental abilities
D. it lasts longer than the other seasons
4). The two best seasons for thinking seem to be _____________.
A. winter and summer
B. fall and winter
C. spring and fall
D. summer and spring
5). According to the passage above, vacations from thinking should be taken ___________.
A. as seldom as possible
B. during spring and fall
C. several times throughout the year
D. during the summer

Questions 21 to 25 are based on the following passage. Lead deposits, which accumulated in soil and snow during the 1960’s and 70’s, were primarily the result of leaded gasoline emissions originating in the United States. In the twenty years that the Clean Air Act has mandated unleaded gas use in the United States, the lead accumulation worldwide has decreased significantly. A study published recently in the journal Nature shows that air-borne leaded gas emissions from the United States were the leading contributor to the high concentration of lead in the snow in Greenland. The new study is a result of the continued research led by Dr. Charles Boutron, an expert on the impact of heavy metals on the environment at the National Center for Scientific Research in France. A study by Dr. Boutron published in 1991 showed that lead levels in arctic (北极的) snow were declining. In his new study, Dr. Boutron found the ratios of the different forms of lead in the leaded gasoline used in the United States were different from the ratios of European, Asian and Canadian gasolines and thus enabled scientists to differentiate (区分) the lead sources. The dominant lead ratio found in Greenland snow matched that found in gasoline from the United States. In a study published in the journal Ambio, scientists found that lead levels in soil in the Northeastern United States had decreased markedly since the introduction of unleaded gasoline. Many scientists had believed that the lead would stay in soil and snow for a longer period. The authors of the Ambio study examined samples of the upper layers of soil taken from the same sites of 30 forest floors in New England, New York and Pennsylvania in 1980 and in 1990. The forest environment processed and redistributed the lead faster than the scientists had expected. Scientists say both studies demonstrate that certain parts of the ecosystem (生态系统) respond rapidly to reductions in atmospheric pollution, but that these findings should not be used as a license to pollute. It can be inferred from the last paragraph that scientists ()
