参考答案

1.B解析：见原文第二段。LeeWildes住在旧金山的一个小公寓里。

2.A

3.A解析：通过句子“ForthefirsttimeinmylifeIgotafairlyclearpictureofmyself”可知。

4.A

5.D解析：参见第三段。

6.C此题为综合理解题。通读全文可知，文中讲述了一张珍贵、稀有的邮票的来历，故C为正确答案。

7.B文中第一段讲述了在太空中“吃”，第二段讲述了在太空中“喝水”，表明在太空中吃和喝都是特别需要注意的问题。

8.C

9.C解析：第三段中的一句话点出了这位非洲学生收集书的目的。这也是为什么他得到了很多人的帮助。

10.A

11.A解析：文中第一段第二行“Beforethedawnofthetwentiethcentury,…”表明是在二十世纪之前发生的。

12.D解析：第三段中的“Certainmenwereverycleveratmeasuringthetimeofdayaccordingtothebeatingoftheirownhearts.”和第四段中的“Theylearnedtousetheshadowscastbythesun.Theymarkedthehoursoncandles,usedsandinhour-glasses,andinventedwater-clocks.”可判断出人们曾经通过数自己的心跳、观察太阳投下的阴影、使用蜡烛、沙漏以及发明水钟来计算时间，但没有讲使奴隶整日整夜地忙碌，所以选项D是错误的。

13.B解析：本题为细节辨认题。第三段第四句讲到“Thesteelwiresusedaregalvanized—coatedwithzinc(锌)tomakethemrustproof”，也就是说，用来制铁丝网的钢丝经过镀锌后以防生锈。

14.D44．答案为D

文章最后一段倒数第2句It'shardtogetstatisticsonlatchkeychildren，theBrownslearned可推知由于父母不愿意透露孩子在家的情况，因此很难统计出钥匙儿童的实际数量。

15.D解析：本题属细节题。文章第三段最后一句“wonnumerousscienceawards”已明确提示答案。

16.C解析：第三段和第四段。这里说前三个需求是物质上的(physical)，而第四个等级的需求是精神上的(mental)。选项C是正确的。

17.C本题为客观细节题。从第二段中我们有看到这样的细节"Thecaptaincametoseehimandwasverypleasedtohaveapatienttolookafter.Hetoldthemantorestforafewclaysandmadetheothersailorsdohiswork."也就是说，当船长听说有人有病就会去为他看病，并且告诉装病的水手休息。

18.B

19.D解析：为猜测词义题。第三段中说到，当顾客接受服务后自然会给一点儿小费。You(指顾客)takeaquarterandputitintheir(指boxboy)handandyouexpectthemtosay，“Oh，thanksalot．”Whenyousay，“I’msorry，Ican’t，”theyfeelalittleputdown．“顾客期待你说感谢的话。而你说：‘对不起，我不能接受’时，他们就会觉得有点儿……”。misunderstood“被误解”；defeated“被击败”；hateful“充满憎恨的”；hurt“感情受到伤害的”，此项最符合上下文提供的语言情景。

20.B解析：andifitisreallygoodscienceitisimpossibletopredict．(好的科学，其研究成果是无法预测的)，因此选B。

21.C

22.B第一、二段指出C项和D项是这位母亲希望她的孩子们说好英语所能得到的帮助。与此同时她也希望她的孩子们能学好韩语，知道自己是韩国人。因此B项是正确的。

23.A解析：该段意为直面人生的诸多困苦keepsusfromfeelingsorryforourselves...forothers...何乐不为!

24.A

25.A

26.B

27.D

28.D

29.C

30.B解析：本文开篇便点明题意。

【虚试指导】坐过飞机的英语表达方式是havebeenonaplane，而不用ride，fly等动词。

34.C解析：本题属习惯逻辑题。下文中举例说明：有些人以他们居住的地方名称来取名字的。

35.B

36.C解析：2001年1月6日之后，

37.D

38.D解析：根据上下文，此处应为“在处理这场冲突的工作中”。

39.A通过上句话中的grown—ups，可推断出本题的答案应是children。

40.D在咖啡里，用in。D项是正确的。

41.D解析：母亲让男孩把叔叔找来共进晚餐。

42.D

43.D解析：我上学的时候电视刚刚开始普及。

44.A

45.C从上文可知：“他需要钉子，而售货员拿给他锤子”，他理应摇头，故应选C项。

46.C作者看到孩子眼中痛苦的表情；不知道怎样改变自己的情绪，用change最恰当。而作者并不是想“压抑”，“掩饰”或者“表达”自己的情绪，故不选A、B、D。

47.B在钢丝上跪下难度更大，因此前面用了even。

48.B解析：对于她个人的生活人们知道得很少。

49.B解析：这篇文章记述了阔别己久的人回乡看望其兄长的妻子和儿子的事。从前一个穷裁缝的儿是一个整天无所事事闲逛的孩子。

50.A解析：walkawayfrom的意思是“走开”。其他选项不符合语境和搭配的要求。

51.A解析：A项划线部分发[au]，而B，C，D项划线部分的发音为[eu]，所以选A项。

52.B解析：画线部分读[ue]，其他选项的画线部分读[e]。

53.D画线部分读[ie]，其他选项的画线部分读[e]。

54.Aattract中字母a读作，其他都读作[ei]。

55.Dthough中字母组合ough读作，是特殊用法，其他都是ou放在ght前的一般读音，读作。

56.D解析：画线部分读[kcm]，其他选项的画线部分读[kem]。

57.DD画线部分读[au]，其他选项的画线部分读[u：]。

58.C解析：A，B，D项划线部分发[ei]，而C项划线部分发[i]，因此选C项。

59.D

60.AA项划线部分发[iks]，而B、C、D三项划线部分的发音是[igz]，因此选A项。

61.B

62.C本题考固定搭配。byoneself意为“依靠自己，独立地”。本句大意为：在许多美国家庭里，父母亲认为应该让孩子自己作决定。

63.D解析：该题测试trydoing的用法，表示“试着用另外一种办法?。而trytodo则表示“尽力做某事”。根据句意，由于写信太慢，所以建议发电报。因此用trysending。

64.C解析：mathematics的s不能省，它是不可数名词。因此只能用little不能用few来形容它的少量。little的比较等级：little—less—least；few的比较等级：few—fewer—fewest。过去我们的数学比现在用得少。

65.D本题为词组辨析题。breakoff意为“停止说话，中断”；breakdown意为“出毛病，抛锚”；breakout意为战争，火灾的突然“爆发，发生”；breakthrough意为“突破，征服”。本句大意为：史密斯博士失败了多次，但他最终找到了一条解决问题的成功之路。

66.A

67.B解析：unless引起条件状语从句，意思是“除非”。

68.C解析：句中有inthepast，故用一般
