参考答案

1.A解析：通过句子“ThekindofdogknownasAlsatianhas220millionolfactory(嗅觉)cells．Manhasfivemillion．”进行计算可知答案。

2.B解析：本题属主旨题。通观全文，文章主要介绍：巴黎的建筑和城市情景。文章没有涉及法语和法国文化，theSeineRiver也只是到最后一段才提到。

3.A

4.B解析：参见第二段：这架单人小型飞车是由120马力的发动机带动的，并有双螺旋桨。

5.C

6.B解析：本题属判断正误题。文章第三段第一句已明确点明：在每年的12月10日，举行诺贝尔颁奖典礼，就是为了纪念他的去世。

7.C解析：参见第二段第一句。

8.D文章中提到“Infastfoodrestaurantsthefoodisusuallyreadybeforethecustomerevenordersit”，其中说明了这种情况的发生率是usually．

9.A解析：本题属推理分析题。文章倒数第三句已提示：西班牙人说“Idoit”是表示在不久的将来要去做某事，而英国人却不这样表达此意，他们是用“Iwilldoit”。

10.C解析：细节理解题。由第二段信息句“Unlikeeveryoneelse,NigelwantedtojointhecontestbecausehelikedplayingwiththeLegosets”理解得知答案选C项。而A、B、D二项文中没有提到，故排除。

11.C

12.D解析：文章第二段提到the1964essaythatfirstmadehername，sheexplainedwhatwasthenalittle-knownsetofdifficultunderstandings可以看出正确答案应为D。

13.D54．答案为D

最后一段谈到的是巴西学生不仅迟到，而且下课后不离开，继续让教授解答问题，A、B、C选项都与本段无关。

14.C见原文第一段。RulonGardner，摔跤运动员，在奥林匹克运动会上获得冠军。

15.B

16.D从第一段结尾到第二段说他特别关注这个病人，可以看出他是为了报答。选项D是正确的。

17.C解析：第1段后半部表达了此意。

18.B51．选项B是正确的。作者以Sam为例，但并不是告诉读者如何修Sam的车(选项A)；文章也并不是谈分析问题的必要性或重要性(选项C和D)。

19.A见文章第三自然段最后一句，即可知答案。

20.D本题是对细节信息进行综合思考推断能力的考查。题中seems一词暗示考生须根据表层意义推断出隐含意义，或对文章提供的情景进行推理和概括，而不可凭借自己的主观看法去猜测。从最后一段第1句和末句了解到thebaby确为铊中毒，而thepoison则来自一种insecticide(杀虫剂)，恰好与D项的解释一致。故推断出D项是正确的。

21.A解析：本题属推理分析题。文章第一段最后一句已明确点明。

22.A

23.D文中最后一段中largemonkeys就指apes。

24.D解析：文中第二段指出MaryOuterbridge将lawntennis这项运动从Bermuda带到了美国的纽约，并且在1874年春天，她在美国打了第一场比赛。

25.B

26.A见原文倒数第二段。一位教授告诉他的学生他将使用这个程序来检验是否有人抄袭。其结果是仍然有人抄袭。300篇文章中，有45篇或15%的文章是从不同的网站抄袭的。所以有255篇是学生自己的作品。

27.C44．答案为C

根据短文最后一句得知冬季树叶少能方便修剪树木，A、B、D皆为干扰项，与原句不符；

28.B解析：参见句子：Thiswasatermusedbytheboatmentomeanthatthewatermeasuredtwofathoms，ortwelvefeet，whichwasdeepenoughforsafepassage．

29.C此题仍是对细节信息的考查。其中关键词是．．experience，thedogfound...。根据对故事情节的推理得出，A项不符合文章原义(最后一段：notanywordsonit所叼纸上无字)；B项不符合逻辑推理(商人愿做亏本生意)；D项不合乎逻辑(对没有本人签字的借据负责)。唯有C项符合故事情节和逻辑推理，故为正确答案。

30.B解析：从最后一段归纳得出答案。

31.A解析：enjoyable愉快的，快乐的；exciting使人兴奋的，令人激动的；experienced有阅历的，有见识的，有经验的；unpleasant使人不愉快的，讨厌的，不客气的。联系题意及上下文应选A。

32.A29．答案为A

固定搭配takeplace表示“发生”。

33.C解析：根据句意，她给读者的建议经常出现在费城公报叫DEARANGEL的专栏里。

34.B解析：对于她个人的生活人们知道得很少。

35.A解析：计算好时间。

36.D

37.C解析：which引导非限制性定语从句。

38.D解析：在此前，父子俩去的都是离家近的学校，但都未能成功。最后，没有办法，只好去了离家较远的一所学校。这里有无奈的含义。

39.A解析：that代替前句中的“drawing”。

40.C本题是词汇题，考查“like”的介词用法，“像，以……的典型方式”，应该是“be+like”，故选

C。

41.C解析：inreply意为“回应”。

42.D解析：根据文章中心可知：我考试中理论知识还不错，但实际动手能力不是很强。因此对于这种实践性较强的问题，不会反应那么敏捷。所以麻选D项。

43.D警察工作很繁忙，所以是不容易的。

44.C解析：本题属推理分析题。通过前边的NewYorkhasoldproblemstosolve，我们知道这里应该选new，前后呼应。

45.A

46.D解析：听听那些在政府办公室的候选人怎么说吧。

47.C解析：英语上常用"some...，others...”这样的句式表示“一些……另一些……”。本句句意为：一些回信的作者是医生，另一些是律师或教育工作者。

48.C

49.A解析：前半句已经说了苹果有数千种。这里只是列举其中的几种，所以应该用including包括……在内。

50.D33．答案为D

此题测试句意理解。上文讲的均为交通事故案例。此处cases意为“案例”。Withthesecasesinmind意思为“(正是山于)注意到、考虑到了这些案例”。

51.A解析：画线部分读[u]，其他选项的画线部分读[u:]。

52.D

53.D解析：选项D画线字母读[u:]，其他选项画线字母读[ju:]。

54.D

55.C

56.A

57.C解析：画线部分读[α:]，其他选项的画线部分读[e]。

58.D选项D画线字母读[ei]，其他选项画线字母读[i]。

59.D解析：画线部分读[ts]，其他选项的画线部分读[s]。

60.D

61.D

62.B解析：本题测试短语；intheeventof意为“如果发生……”。本句大意为：如果发生火灾，旅店客人应保持镇定。

63.C解析：考查动词辨析。句意为：“我们将很快耗尽自然资源，同时也正用有害化学物质污染我们的环境。”pollute“污染”符合题意。protect“保护”；save“拯救”；fight“战斗”。

64.A解析：本题考查代词的用法。another表示“另一个”，指代三者之间，theother，others，both仅指代两者之间。

65.A解析：定语从句前的人称代词复数应用those。

66.C解析：本题测试定语从句。why引导的定语从句修饰thereason。本句大意为：我写信的原因是要告诉你我的考试结果。

67.A解析：charge表示“索价；要……支付”。

68.C解析：此题考查固定搭配。put…touse意为“把……投入使用”。

69.A本题为近义词辨析题。way一般指比较抽象的“方法，方式”；method指“具体的方法”；manner指“一种行为或方式”；fashion指“时尚，流行”。本句大意为：我的父母亲总是让我有我自己的生活方式。

70.C解析：该题测试动词短语feellike在交际中的用法。C选项Ifeellikestayingathome．=Iwanttostayathome．A选项Noway.意思是“没门儿，别想”，不合题意。

71.B解析：根据句意可以推断后半句是对前半句的补充说明，所以用anyway(无论如何)。however“转折”，therefore“结果”，though“尽管”。

72.A

73.C本句为强调句型题。强调句常用“itis．．．that”构成，把被强调的部分放在中间，只有当强调对象是人时，that可用who来替代；其他情况一律用that引导。本句大意为：只有通过实践，人们才能学会游泳。

74.C参考译文：玛丽把她的钥匙落在了办公室，所以她进不了家门。把什么东西忘在什么地方的“忘”不是"forget"，而应该是“leave”，在此题中应该用过去式“left”，“进不了家门”就是“被锁在家门外面”，应该用被动“bekept”，故选C。

75.D解析：stayup意为“熬夜”。

76.B解析：因果关系，用B。

77.C解析：usedto后接动词原形，表示过去经常做……。

78.A

79.D解析：本题考动词短语的辨析。breakaway意为“脱离”；breakout意为“爆发”breakthrough意为“突破”；breakoff意为“中断”。结合句意，故D项正确。本句大意为：我不知道他为什么一句话讲了一半就停了。

80.D

81.61．短文写作一般给出题目，或规定情景，或要求看图表作文，或给出关键词，或给出每一段的段首句，
