参考答案

1.D由第一段的最后两句可知本题选D项。

2.B解析：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)。

3.C

4.C解析：文章第一句提到作者每年这个时候都会收到许多抱怨感冒不容易好的信件。而医生是不会收到类似的信件的，病人通常会直接去看医生。由此推断这篇文章是从杂志上选下的。

5.D解析：奉题考查的是对推理的把握能力。该题可以从文章第五段第一句…whenhesaidthattherewasgoodreasontobelievethattherewouldsoonbemoreyoungchildrenlivinginMalupit可以推导出D选项。从前面两段也可看出两位家长都不赞成关闭学校。

6.D解析：参见倒数第三段。

7.C解析：本题属推理分析题。文章第二段第三句中的"“thefamilyispartoftheneighbor-hood”可知：neighborhood(邻区)比family(家庭)大。

8.B

17.C解析：第二段首句与C意思相同。

18.C解析：此题为细节、理解题。文中的第4段明确地阐述了事情发生的经过，邮票的问题在于是用词错误，并非是拼写错误，故C为正确答案。

20.A解析：由下文凯特不明白纳迪亚为什么懂英语而不说话，可以推知正确答案为A。

24.A在第六段中，Cusick说马戏团在雇用他时就已经知道他是艾滋病病毒携带者，因此在他花费长时间的准备之后，又没有让他登台演出就解雇他是不公平的。

34.C解析：fourthgraders四年级的学生，alphabeticalorder字母顺序。这位先生说，每年你们都是按字母的排列顺序排队去不同的地方。

35.C解析：本题考查辨别词义。event意为“事件”chance意为“机会”occasion意为“时机，场合”：affair意为“事件，事情”。根据上下丈，过生日应该是一种场合。

36.B解析：anentirecontinent意为“整个大陆”。

37.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。

38.A词组题。根据句意知道应该是“妈妈照顾孩子们”，“照顾”应该是“takecareof"，所以选A。

39.C

40.Aless...than...使罪恶比现在少。

41.C此处应用一般过去时，read的过去式与原形相同。

42.B解析：四个词的意思分别是：discriminate(常与against,infavorof连用)歧视；不一视同仁，区分，区别待遇；distinguish(常与from,between连用)区别；区分；divide(常与in，into连用)分开；划分；derive(常与from连用)得来；得到，源自。蜜蜂的超强记忆能力意味着它们能够在50种不同的气味中分辨出它想要的气味。故B是正确答案。

46.C

47.B

51.D

52.C解析：画线部分读[i]，其他选项的画线部分读[ai]。

53.C解析：画线部分读[k]，其他选项的画线部分不发音。

54.AA项划线部分发[a：]，而B、C、D三项划线部分发[c：]，故选A项。

55.C解析：画线部分读[au]，其他选项的画线部分读[^]。

56.C

57.BA、C、D三项划线部分发[t∫e]，而B项划线部分发[tjue]，因此选B项。

58.C

65.C解析：报纸上所登的东西用介词in。选项C是正确的。句意为：“我申请的工作是我在报纸上广告栏看到的。”

66.C

67.D解析：此句为以letus开头的祈使句，其附加疑问句应用willyou，而Let's开头的祈使句，其附加疑问句用shallwe。

68.Asucha(an)后接单数可数名词。

69.D解析：本题测试动词词义。ensure意为“确保”；assure意为“担保”；resume意为“重新开始"；assume；意为“设想，假定”本句大意为；科学家认为火星上没有生命。

70.D解析：ofone'sown“属于自己的”。“汽车”为泛指，所以必须用acarofherown表示。

71.C解析：本题测试时态用法。因captain和warn之间是被动关系，所以用现在分词的被动形式，又因warn的动作发生在change动作之前，故用分词的完成式，Havingbeenwarned在句中作时间状语。根据句意，C项正确。本句大意为：受到警告后，船长改变了航向。

72.D解析：本题考查主语从句的用法。因为主语是mybrother，而且引导词在从句中作主语成分，故选who。whom只作宾语成分，what/that都引导事物。

73.Dpay支付；spend花费；cost花费(主语为物)；afford支配得起。句意为：那个漂亮的包太贵了，我买不起。

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.Bfindout是“查明”之意。

76.C解析：but多与nothing、nobody、all等连用：except表示“除了；除去”；besides是“除了……还有”的意思；beside表示“在旁边”。

77.A解析：Awareof是固定词组，意为：意识到、知道。选项A是正确的。

78.D解析：So引导的短语前置
