参考答案

1.A解析：文章第三段提到“Insteadofstealingcars,heletssomeoneelsedoitandthenwaitsforthecar-ownertoplaceanad(启事)inthenewspaperaskingforhelp.”故正确答案应为A。

2.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。

3.C解析：文中第四段写到了游客游览LostSea的情景，结合文章其他段落，可知日前CraigheadCaverns是—个旅游胜地。

4.B

5.B解析：从文章首段首句LastAugust，JoeandMaryMahoneybeganlookingatcollegesfortheir17-year-olddaughter可以看出正确答案。

6.D根据上下文，工人阶层的工作性质是被管理并且是遵守规则的。那么，其规则肯定是明确的。D项是正确的。

7.C解析：参见最后一段。

8.D解析：选项B是错的。文章不光讨论的鸟也讨论了鱼、蛇等；文章讨论的焦点不是眼睛而是眼皮。选项D是正确的。文章讨论了保护眼睛的是什么。

9.D解析：本题为细节题。根据文章第1段最后一句Hesaiditwasa1950or1951Chevrolet．和第2段第1句中的Ordinarily，searchingthroughthefilesforownersofelderlyChevieswouldhavebeenanimpossiblydifficulttaskbecausethereweretwoandahalfmillionsuchcars．我们不难看出Chevrolets与Chevies所指的是同一个东西，故应选D。

10.B第三段第一句中写到“becauseofthis”，其中this就是指“shyandtimid”。

11.B解析：参见第二段。人类把这种鸟圈入特定的地点进行喂养得到了一定的保护。但同时，它们也似乎对人类更感兴趣。从而破坏了人类的正常生活。这就是人们用不同的手段杀死它们的原因。

12.C46．答案为C。根据第一段，forbringinggunsandbombstoschool作出该项选择。

13.C解析：主旨理解题。全文一开头就点明了“openingabankaccountisnotverydiffcult．Thetroubleisfindingthecashtoputinit”；然后指出学生的收入不高，银行可以怎么样来帮助学生打理手头有限的资金；最后提出“Isuggestyouopenyouraccounttoday．”同时还不忘顺便提及“ifyouopenanaccountthismonth，we'llgiveyoufreeaspeciallydesignedlecturenotefolderwithaclipboard，padandball-point"以便吸引学生来该行进行储蓄。

14.B通读全文，可知文章主要是论述太阳斑点的形成以及与磁力的关系。所以B更为符合。

15.C解析：根据这句话中的palaces和museums可判断出statelyhomes指的是向公众开放的巨大的房子。

16.D文章第二、三段指明两个事故后均无法判断事故责任，但司机都被关人监狱等候结果。

17.D解析：第六个笔友。

18.B解析：第三段。从这段里我们知道，Williams会写书、画画、做珠宝，所以说他有很多的艺术天赋。选项B是正确的。

22.C解析：本题为细节辨认题.由文章第二段"Somepeopleontheearthdonotgetverymuchrain.Yet,theystilldonotbecomedeserts.Thisisbecausetherearesomesmallgreenplantsgrowingthere.Plantshelpkeepwaterintheearth.Plantsdonotletthewindblowthedirtaway"可以将A和B排除,而D文中没有提到,所以得出正确答案为C.

23.D

24.D

25.C解析：本题为细节辨认题。由第三段“InNepal，hikerspickeduptrashonMountEverest"可以得出A项正确；由谊段“IntheUnitedStates，childrenplantedtrees"可以得出B项正确;由本段“artistsdrewpicturesonwallsnexttohighways，andmusiciansgaveconcertstosupporttheworkofenvironmentalgroups"可以得出D项正确。因此，该题可用排除法选C。

26.D文中A、B、C项，均有提到，唯有D项“playingmusicthatsoundslikemusicoffamousbands”未提到。

27.A通过文章的第一句就可以判断A项是正确的，其他选项只是文章讨论的一个细节。

28.B解析：细节推断题。根据最后一段中“Whatpositionisheseeking?Anythingthatwillpayhimaround＄35forunskilledlabor．”可得出正确答案为B。

29.B解析：第一段。军情五处的头儿说大英帝国正面临国际恐怖主义的威胁。

30.D由第二段内容可知A、B、C三项都是Nigel接近Alicia的手段和方式，故排除；由“Get—tingthethousand—dollarprizewasmoreimportantthananythingelse．NigeldecidedtobefriendAlicia．”得知选D项。

31.D

32.B根据上下文，该句的意思是“那就是……的原因(That"swhy…)”。

33.C解析：四个词组的意思分别是：asto关于，至于；asmuch同样多；upto多达，到……之多；suchas诸如……，像……那样的。这里需要一个修饰时间量的介词短语，因此C是正确答案。

34.C解析：见上一条。

35.B

36.A这篇文章介绍了1998年两位诺贝尔和平奖获得者的事迹。awardaprizetosb．授奖予某人。挪威诺贝尔委员会决定将1998年诺贝尔和平奖授予JohnHume和DavidTrimble。

37.D解析：有些人以为他们也在选举自己的总统。事实上他们选举的不是总统。再重申一下，他们选举的是代表。而这些被选出来的代表叫选举人。他们是选举团的成员。

38.D29．答案为D

此题测试句法和短语理解。填充处与句子时态有关。在英语中，站在今天的角度谈论的前一天为“yesterday”，从过去的某个时间起谈论的前一天为"thedaybefore”，故选D为答案。

39.C解析：inahurry着急。

40.B

41.D解析：本题属于词选题。本句要说的意思是：我认为他的歌还不错，但是也不值数以千计的信件。故选worth(值得)。

43.D解析：根据前后两个句子的意义及转折关系可以判定应选D项。

44.D

45.A

46.D解析：本题属逻辑题。这句和上一句要表达的意思是：个人体育运动没有团队，没有任何竞争。

47.D解析：见上一条。

48.D解析：根据71题的分析可以得出该题答案为D。

49.B解析：但有些人带的显然是非常危险的物品。

50.A长期来说，用inthelongrun。而intheshortrun表示的意思正好反，意思是“短期来讲”，不合逻辑；quick，slow意思都不合适。故选A。

51.C解析：画线部分读[a:]，其他选项的画线部分读[3e]。

52.B

53.D解析：画线部分读[w]，其他选项的画线部分不发音。

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

55.C解析：该题测试元音字母o的读音。选项A、B、D中o发[eu]音；选项c中o发[c]音。

56.AA项划线部分发[ai]，而B、c、D三项划线部分的发音是[i]，所以选A项。

57.A画线部分读[z]；其他选项的画线部分读[s]。

58.B解析：本题属元音字母辨别的考查题，可利用排除法。A、C、D三项当中的发音均为[/\]，只有B项中发音为[jue]。故选B。

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

60.C画线部分读[i]；其他选项的画线部分读[ei]。

61.A参考译文；我们应该立即做一个决定来禁止工厂排放未经处理的污水。“做决定”应该是“makeadecision”，故排除C、D。”禁止工厂排放未经处理的污水”是这个决定的目的，故应该用动词不定式“tostop”表目的，综合这两点考虑可知正确答案为A。现在分词“pouring”引导的短语做宾语补足语修饰限制

factory。

62.D

63.C

64.B

65.C解析：本题为固定搭配题。besensitivetosth．意为“对……敏感”。本句大意为：有些植物对污染非常敏感，它们只能在完全无污染的环境下生长。

66.B本题考动词的词意辨析。treat意为“治疗”；adjust意为“调整”；adapt意为“适应”；remedy意为“治愈”。结合句意，故B项正确。本句大意为：无论是阴天还是晴天我的相机都可以调节拍照。

67.B

68.A解析：“only+状语”置于句首时，句子倒装。

69.D解析：本题为词义辨析题。profit意为“获利，盈利”；exploit意为“开发，剥削”；mislead意为“易误解的”；frustrate意为“挫败，使感到灰心的”。本句大意为：找工作会使人感到沮丧失望的，因此，做好准备对你很重要。

70.C解析：首先应判定该空白处在句子中所处的位置，即介词位置。读懂全句可知，此句要表达的是“一……就……”或“在……后立即……”的意思。on+表示动作的动名词的结构表示“一……就……”或“在……后立即……”的意思。

71.B解析：traffic为不可数名词，故用
