六、写作(1题)82.Forthispart,youaresupposedtowriteacompositionin100-120wordsaccordingtothefollowingtopic.

描写一件你认为(或者你经历的、听说的)最有意思或最有意义的事。

参考答案

1.A

2.D答案为D。文章中第一段讲述哲学家能透过事实抓本质，时空是哲学家探究的领域。第二段阐明人人都可以做哲学家。因此选项D符合原文。选项A、C文中未提及；选项B是细节。

3.C

4.C解析：文中最后一句提到“statisticalprobability”，意同C。

5.A45．答案为A

根据第三段和最后一段得知钥匙儿童独自在家，感到的不是自由，而是恐惧。

6.B解析：做题方法就是在原文中找到该词，瞻前顾后。本题相对简单，因为原文已经给出了它的定义。原文第四段提到：Thisresultsinunusualandself-destructivebehavior.calledzoochosis．故正确答案应为B。

7.D解析：参见原文最后一段。

8.B本题为推理题。文章告诉我们，警方最初只发现一男一女在车内被谋杀，唯一的线索只是一个目击者，证明曾见过一辆1950或1951型号的雪佛莱汽车从死者车旁经过。但如果没有计算机的帮助，要从250万辆这种型号的车辆中找出凶手的车是不可能的。所以，计算机的帮助成了抓获凶手的关键，证人仅提供了线索，但并未亲自去抓捕罪犯，所以B正确，而C错误。A和

D与文中内容相矛盾。

9.C文中第三段第二、三句讲述了BenSands发现LostSea的故事。

10.D解析：第二段后半部分。樱桃树比李子树小需要摇晃的频率就高些。选项D是正确的。

11.B参见第一段句子：“However，theseearlyimmigrantsfromEuropedidn’twanttosharethelandwiththenatives.TheykilledoffmanyoftheIndians，seizedtheirlandorpushedthemofftolandsfartheraway.”

12.A

13.C

14.D推理判断题。

【应试指导】由文章第二段最后一句话可知，什么时候能收到回复要看接收者查看信件的频率。由此可推知，作者认为电子邮件的不足之处是回复依赖于接收者查看信件的频率。

15.B解析：本文是一篇说明文，第一段即道出全文的主旨是要说明一种新型客机在投入使用之前所做的许多测试中的最重要的两项。第二段对其中一项测试tanktest进行了说明。该段落的第2～4句说明了为什么飞机的结构要牢固。第5～7句从物理学上说明飞机在空中产生爆炸的原因。接下来才说明tanktest测试的目的是Totestthestructureoftheplane和测试方法。第二段末尾提到通过测试，Engineerscandiscoverwhichpartoftheplanehasbroken.Thenthatpartismadestronger.可以判断B选项涵盖了上述意思。

16.A解析：instantfriends指立刻成为朋友，因此A为正确答案。

17.A通过上下文可知。

18.A解析：第五个笔友。

19.C

20.B

21.C解析：第二段首句与C意思相同。

22.D44．答案为D。用排除法，选项D与第四段第四句prejudicecanbeevenhardertobreakdownandignoranceinevitablyrepresentsbyfarthegreatestbarrierofall不符。选项A在第二段第一句提到；选项B在最后一段最后一句提到；选项C在第三段第三句提到。

23.C

24.D解析：2000年是克林顿在任美国总统的最后一年。

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

26.D由第一段段意可知，Nigel是因在学校学习好被选到计算机实验室帮助老师而得到一些酬劳。A、B、C三项在本文中都没提到，故排除，答案选D项。

27.B

28.B最后一段指出这座城市的地下有座被遗弃的煤矿，煤矿坑道的倒塌带动了道路的下沉，整座城市随时都会倒塌。B项是正确的。

29.B解析：见原文第三段。这些网址是靠广告赚钱。第一段提及大的网站受到攻击。

30.C文章第三段表明，英语和美语在语法上仅有一小部分的区别。

31.B解析：通过pass可以确定为B选项time，pass=spend。

32.C解析：快读一遍试题。skimthrough意为“快速浏览”。

33.Dsomeone某人。这两句话的意思是：我们是该用手机、笔记本电脑、照相机等来满足我们的需求，但我们还可以在不想被打扰时关机。如果知道怎样使用手机，就可以避免它的弊端。

34.A解析：自从9·1l事件以后，行李检查已经从旅客手中没收了似乎没有伤害力的物品。如：指甲刀、打火机等。

35.D解析：根据文章内容来看，此处进一步谈到在指方向问题上的第三种人，still表语意上的递进关系。

36.A

37.B29．答案为B

which引导定语从句，代替前面的Ronald，并做从句的主语。Who只能代替人，Ronald此处是名词，并非人，故不选A。that只引导限制性定语从句。what引导名词性从句做动词的表语和宾语。

38.C解析：冬季奥运会的项目有滑雪、滑冰等。

39.C

40.C句意为：“这些因素在很大程度上都在人们的控制能力之内。”control是正确答案。

41.D解析：前文说了苹果树开出白色或粉色的花，然后经过施肥，苹果开始成长。after指……之后，then指“然后”，when指前后两个动作同时，before指……之前。

42.D

43.D解析：what作mean的宾语。

44.C解析：他将在星期四庆祝他的23岁生日。

45.C21．这篇文章在讲一个梦。地点是剧院。在剧院的大厅里，后面说的是坚持要作者做一件事，所以不可能是帮助(help)，也不可能是简单的相遇(met)。Stop拦住。选项C是正确的。

46.B解析：enjoy享受乐趣。此句的意思为享受在此的乐趣。

47.B见上一条。

48.C此句意为：重新考虑他们的错误之处。

49.A解析：wearaheavyovercoat意为“穿着一件厚大衣”。

50.A整句话连起来的意思是：价格贵100倍并不意味着酒的味道就好l00倍。选项A是正确的。

51.DA、B、C三项的划线部分发[3en]，而D项划线部分发[∫en]，因此选D项。

52.C解析：画线部分读[k]，其他选项的画线部分不发音。

53.B解析：画线部分读[u]，其他选项的画线部分读[u：]。

54.D解析：选项D画线字母读[e]，其他选项画线字母读[i]。

55.C画线部分读[i]；其他选项的画线部分读[ei]。

56.D

57.B

58.C4．选项C画线字母读[]，其他选项画线字母读[u]。

59.D解析：画线部分读[ei]，其他选项的画线部分读[i]。

60.Ccrop中字母c读作[k]，其他都是读作[s]。

61.B解析：考查的是代词的用法。However无论怎样，whatever无论什么，wherever无论哪里，whenever无论什么时候。根据题干，应是无论什么样的问题。选项B是正确的。句子大意：无论你有什么问题，找这儿的Harry帮你。他什么都知道。

62.B解析：bringout“把……拿出来，显现出……，使……问世，出版”；bringup“养育，提出话题”；bringto“使……复生，恢复”；bringabout“引起(事故、变化)，导致，致使”。故正确答案为B项。

63.B

64.A

65.C解析：本句中含有结构too…to。

66.D

67.B时间状语从句中要用一般现在时表示将来。

68.D

69.A

70.C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”符合句意。protect“保护”；save“拯救”；fight“战斗”。

71.A16．答案为A

虽然他说他不饿，但他早餐吃了很多。根据句意，只有although正确地表达了主从句的逻辑关系。unless“除非”；despite“不管……”，一般接名词(词组)；even“甚至”。

72.B解析：本题为词义辨析题。install意为“安装，安置”；devise意为“设计”；format意为“安排……格式”；equip意为“装配”，常和with连用。本句大意为：夏威夷大学的刘易斯.海门设计了一系列新的试验，在这一系列实验中有一些动物学会了理解句子。

73.C解析：此项引导非限制性定语从句。正常语序应是“onlyone-thirdofwhom”。whom引导从句置句首。又因whom是of的宾语，一起置句首。

74.B解析：分词短语作状语时，其逻辑主语与句子主语相同，本句主语是I。选项B=WhenIreturnedtotheroom，Ifoundthebookmissing.

75.D

76.B解析：couldhavedone“(过去)本来可以做到，实际未做”。其他三个选项指“现在”，不能用来谈论与过去事实不符的事。此类用法还有s
