单选题Ellsworth Huntington’s conclusion was based on _____.A variations of his own mental abilities from season to seasonB the result of research done by him and other scientists among peoples in different climatesC detailed records of temperature changes in different placesD detailed records of different ways of thinking among peoples in different climates

考题 Passage FourIf 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 year. A noted scientist, Ells- worth Huntington (1876-1947) concluded from other men's work and his own among peoples 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 is. 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 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!46. According to the passage, your mental ability ______.A. depends on your attitude towards people in different time of the yearB. changes for the worst when you dislike most people in hot seasonC. will be best in winter and worst in summer if you want to be creativeD. turns to be more powerful in spring than in any of the other seasons

考题 The dog has always been considered man′s best friend.Always noted for being particularly?faithful in watching over children,he also has his place by the fireside,in the cow pasture,on the?sheep range(放牧区),and beside the hunter in forest.He is easy to train,works hard,and often?performs astonishing feats.And in the frozen polar regions he was once the principal motive power,before being lately displaced by the plane and helicopter. Because he howls or whines in the presence of impending death,the dog was once thought to?have supernatural powers and believed to be capable of seeing gods and ghosts invisible to men.Actually,the.basis for these beliefs lies in the hound′s sensibility to people′s feelings and his superior?hearing ability and sense of smell,which enable him to detect signs hidden from human observation.His record of saving lives is outstanding,for he often gives warning of fire and other dangers not noticed by his master. The dog′s major contribution,however,has been to medical research.Both his diet and his?structure are comparable to those of the human being,and so he has been the subject Of countless?demonstrations and experiments.Open-heart surgery has been made possible largely because of the?dog.But his sacrifice has repaid his own species as well by safeguarding it from rabies(狂犬病),distemper,and other diseases. The article does not say whether the scientists′experiments with dogs have__________.A.benefited animals other than dogs B.served man C.helped other dogs D.contributed to medical knowledge

考题 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 （）A、are puzzled by the mystery of forest pollutionB、feel relieved by the use of unleaded gasolineC、still consider lead pollution a problemD、lack sufficient means to combat lead pollution
