六、写作(1题)82.Writing

参考答案

1.B解析：参见最后一段。

2.A解析：见原文第二段。两辆车撞在一起。

3.A参见文章第一句。

4.B解析：本文通过对不同时期艺术家的比较，作者分析了艺术的一个共同问题：“什么是真实”，结论是虽然不同时期和地域艺术的表现形式不同，但都反映了当时人的生存状态。

5.A根据文中第三段第六句“Thousandofpeoplelinedtheroutetoencouragehim…”可知，答案为A项。

6.D解析：第4段中指出只有12%而且大多数，所以D项的表述错误。

7.B解析：由第一段的最后一句“…mostofushavebeenbroughtuptoeatcertainfoodsandwesticktothemallourlives.”可知B为正确答案。

8.D解析：方法同第44题。根据已知条件：退休、周末工作、轻松的类似接电话之类的活儿。第五条广告符合该要求，其电话号是897—980-7654。

9.D本题为细节辨认题。文章第一段第一、二句讲到“Abudget(预算)isaspendingplan．Itcanhelpyouspendmoneywisely．”即：预算就是一个花钱的计划，它能让你明智地花钱。

10.B解析：第三段。种植玉米的区域在中西部。选项B是正确的。

11.A解析：从文章中可以推断是种族歧视的原因。

12.B

13.B参见第二段第一句。

14.A

15.D

16.D解析：文章第一句话Thedaysof...appeartobenumbered．指欧洲人在咖啡馆中消磨时光的时候少了，所以D正确。

17.D解析：本题为词义推理题。现代计算机工业的物质基础是硅，而人类属于有机体，其物质基础是碳。所以作者把机器人和人类分别抽象为硅和碳。

18.B解析：本题考查的是推理能力。该题可以从最后一段最后一句得出答案：“压差越大，风越大”。可见大风是由于压力差异造成的。

19.A

20.A根据第一段，他们认识不久，当Emma提到没别的事可做时，Alex就去拿书给她看，说明Alex很重视他与Emma的友谊，借给她书看只是为了表示友好而无其他目的。所以选A项。

21.C

22.B

23.B解析：这是一个工作招聘广告。一共六份工作。首先要看题干所给的已知条件，抓住一些关键词，诸如年龄是21岁，兼职，能工作的时间是晚上，依据这些条件到文中去找。第二条招聘广告中的Parttimejob，workduringtheevening，需要的年龄是18～26等都符合题干的要求。

24.D解析：见原文第二、第三段。他既给(纽约人)杂志写文章，又给孩子们写书。

25.B解析：见第一段第二句，从中可知过去人们对大学教育的作用给予了充分的肯定。

26.D从文章最后一段“Inl793，theLouvrebecameapublicmuseum，justasitisnow”可得到答案。

27.C

28.A文中的deeper指“人睡得深，睡得沉”，可以用heavier代替。

29.B解析：细节辨认题。根据第二段第四行“Thelibrarywillmaintainregularhoursduringtheweek，butshorterhoursonSaturdaysandSundays"可得出正确答案为B。

30.B参考文章第三句，可知theLostSea是世界上最大的地下湖。

31.D解析：这篇短文涉及美国的选举程序。2000年11月7日是美国的特别的日子。这一天全国的选民都在选举代表。这一日也叫总统大选日。

32.C解析：前半句的havingalist的逻辑主语应为shoppers，即买东西的人。此句并不指售货员，所以B项不成立。custom不是“顾客”的意思，manager也无从谈起。

33.D解析：见上一条。

34.B解析：不让孩子听音乐，也就是让孩子“安静地”做作业。

35.C21．答案为C。在英语中neither...nor...一构成一个句型，但有时也用not...，nor...构成同样句型，意为“不……，也不……”。其他选项在句中均不能构成句型。

36.C

37.A

38.Cseems“似乎”。句意为：“但似乎总是当我们放弃了某些东西后，我们又能从那里得到一些新的东西。”

39.Cgrade这里指年级。

40.Dhardly意为“几乎不”；此处也不用比较级；hard本身可做副词，应选D。

41.D根据下文他去买钉子，可知他需要钉子，故应选D项。

42.B解析：as“当……的时候”。当我走过五金货架的时候，我朝店员点了点头。

43.A解析：由后面“peak”可推测此处填“精力充沛的”。

44.D24．答案为D

根据句意stirup“引起、激起”为正确选项。passout带宾语时为“分发”；

takeaway“拿走”；backup“支持”。

45.C解析：Somebody和后面的thenthewholeclasswaslaughingwithopen-heartedenjoyment中的thewholeclass形成逻辑关系：有人笑了起来，接下来全班都开心地大笑起来。

46.D解析：living后必须接介词in，意为“居住”；cultivating意为“耕种”；reclaiming意为“开垦”；只有exploring有“探察”的意思。

47.D解析：DavidTrimble在最关键的时刻展示了他作为政治家的巨大勇气。

48.C

49.Acase箱子，box盒子，load装载，fiu填满。根据上下文，买了一箱红酒，几家分。选项A是正确的。

54.D解析：该题测试语音的同化现象。受邻近语音的影响，词尾(加ed，或加s)读音发生同化。选项A、B、C中ed发[d]音，选项D中ed发[t]音。

55.AA项的划线部分发[c：]或[c]，而B、C、D三项划线部分发[a：]，因此选A项。

56.B

57.
