32、0）A.Why are projections of the effects of changes in water vapor levels on the climate so inaccurate?B.What are the steps in the process that takes place as CO2 absorbs long-wavelength radiation?C.How might our understanding of the greenhouse effect be improved if the burning of fossil fuels were de

33、creased?D.What might cause a series of regular increases and decreases in the amount of CO2 in the atmosphere? 解析：依据第三自然段和第四自然段第一句话。2.The author refers to the Venus primarily in order to _.（分数：1.00）A.show the inherent weakness of the greenhouse effect theoryB.show that the greenhouse effect works on

34、 other planets but not on the earthC.show the extent to which Earths atmosphere differs from that of the VenusD.supper the argument that the CO2 level in the atmosphere has a significant effect on climate 解析：作者提到金星，主要是为了证明这一论点：大气中 C02低含量会对气候造成重大影响。作者在第二段第一句话提到了这一论点。他以金星为例，正是为自己的论点提供依据。3.What does th

35、e author think of society toward motorists?（分数：1.00）A.Society criticizes the motorists severely.B.Huge car parks are built in the cities and towns.C.Society overlooks their rude driving. D.Victims of accidents are nothing.解析：根据第二段前六句。答案 A与短文内容不符，很容易排除，答案 B和 D是本段提到的两个事实，与作者的评论关系不大。4.Which of the foll

36、owings is NOT mentioned as a way against traffic accidents?（分数：1.00）A.Build more highways. B.Stricter driving tests.C.Test drivers every three years.D.Raise age limit and lay down safety specifications.解析：要修更多的路没有提到。其余三项都明确提到。5.Why does the author say: “his car becomes the extension of his personali

37、ty”?（分数：1.00）A.Driving can show his real self. B.Driving can show the other part of his personality.C.Driving can bring out his character.D.His car embodies his temper.解析：作者说“他的车成为他个性的外延”，是因为开车表现了司机的真实自我。第一段最后三句话是选择的依据。第一句举例说明，平时安静、平和，一开车，就可能变得让你不敢相认。第三句中韵“hidden”及“brought to the surface”，也能说明。而其余三项

38、只是表现自我的某个事实。6.“Candour“ means _.（分数：1.00）A.frankness B.obsequiousC.optimismD.sarcasm解析：Frankness 意为“坦率”。这是根据上下文猜测词义的题目。看到 candour，许多可能不知道它的意思，但下一个句子用同义词 frankness替换它，只要知道 frankness意为“坦率”，就应该猜得出candour的意思。7.This passage most probably is _.（分数：1.00）A.a book reviewB.the preface of a book C.the post scr

39、ipt of a bookD.the conc4uding part of a book解析：这篇短文很可能是该书的前言。第二段首的 This book is written for指明该书的读者对象；第三段首句和第四首句说明了该书要达到的两个目的。据此，我们可以断言：这是一本书的前言。8.The passage suggests that a large decrease in the amount of CO2 in the atmosphere would result in _.（分数：1.00）A.at least a slight decrease in global temper

40、atures B.at the most a slight increases in short-wavelength radiation reaching the earthC.a slight long-term increase in global temperaturesD.a slight short-term increase in global temperatures解析：这篇文章暗示大气中 C02含量锐减至少会导致全球气温小幅度下降。我们的依据是第二自然段最后几句话。在这几句，作者介绍了两种理论：根据第一个理论，如果大气中的 C02减半，地球就会完全被冰所覆盖。根据第二个理论

41、，如果大气中 C02的含量减半，全球气温会下降三摄氏度。综合起来，气温至少会有小幅的下降。其余三项都说气温会上升。9.The passage suggests that if there were a slight global warming at the present time, it would be _.（分数：1.00）A.easy to measure the exact increase in temperature because of the abundances of temperature recording stations throughout the worldB

42、.difficult to prove that the warming was caused by the burning of fossil fuels C.easy to demonstrate the effects of the warming on the water vapor in the atmosphereD.difficult to measure the increase of CO2 in the atmosphere because of local variations in amount解析：读懂最后一段，可选出答案 B。10.The author is pri

43、marily concentrated on _.（分数：1.00）A.explaining the effects that the burning of fossil fuels might have on climateB.illustrating the effects of CO2 on atmospheric radiationC.discussing effects that changes in the CO2 level in the atmosphere might have on climate. D.challenging hypotheses about the ef

44、fects of water vapor and CO2 on climate解析：作者主要讨论大气中 CO2含量对气候造成的影响。作者在第二段和第三段专门讨论这一问题。A 不能选，因为作者只是轻描淡写地讨论这一问题。11.We need to know something about the structure and operation of science because _.（分数：1.00）A.it is not easy to understand the things that excite and frustrate scienceB.science affects almos

45、t every aspect of our life C.scientists live in a specific substructureD.it is easier to understand general characteristics of science解析：根据第一段中的 Since it touches almost every facet of our life，educated people need at least some acquaintance with its structure and operation来判断。12.Captain Sentry, in t

46、his passage, demonstrates that he is noteworthy because of his _.（分数：1.00）A.domineering qualityB.modestyC.honestyD.frankness 解析：Captain Sentry 让人觉得他值得注意，因为他坦率。根据 Captain Sentry的谈话内容，就可以断定他是一个坦率的人。他老是悲叹，他在这个行业(即部队)本应该把一个人的优点放在首位，但厚颜无耻却胜过了谦虚。谈到这一点，作者从未听到他愠怒的声音，但坦率地承认他离开部队，是因为他不适应部队生活。过于诚实和按部就班的行为妨碍他挤进

47、指挥官恩宠的人群。另外，根据总结性的语言 With this candour does the gentleman speak of himself and other (这位先生以这样的坦率谈自己和别人的情况)和 The some frankness runs though all his conversation (以同样的坦率贯穿于他的谈话)就可以选准答案。13.According to the passage, “scientific subculture “means _.（分数：1.00）A.cultural groups that are formed by scientistsB.people whose knowledge of science is
