六、写作(1题)82.Forthispart,youaresupposedtowriteanessayinEnglishinabout100-120wordsbasedonthefollowingsituation.Remembertowriteitclearly.

写一一篇有关压力的文章。内容包括：

(1)压力是什么?

(2)减压的办法。

参考答案

1.B解析：全篇列举了不同的鸟保持清洁的方式不同。

2.C解析：第一段及全文都说明本文的中心内容是教孩子如何应对紧急情况。

3.B解析：由第二段“Theideaneverappealedtomeverymuch,butoneday,afteraheavyshower,IhappenedtobewalkinginmygardenwhenInoticedahugenumberofsnailstakingastrollonsomeofmyprizeplants.”可推知作者的态度是生气的。

4.A解析：综合概括题。根据对第三段的分析可得出正确答案为A。

5.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。

6.A

7.B解析：参见第一段。此题是对词汇的考查。valley意为“山谷”，肯定是在两山之间了。

8.C

9.A解析：第2段开头讲现在政府采用“progressivetax”，所以交税多的人即为富裕的人。

10.C解析：参见最后一段。要解决秃鹫远离铅中毒的方法有：猎人应当用其他种类的子弹；或者，秃鹫根本就不应该被放回大自然。

11.D解析：本题为细节信息推理题。题中关键词为Howlong．．last(历时多少年)。这类题只需查找文中有关时间信息，再进行计算即可。第2段第2句theKnightsofLabour．．．formedin1869，第3段末句by1890．．．theunionhaddiedout是该组织的起止时间，计算之后得出历时21年。故D项是正确的。

12.C第二段提到母亲对三个孩子都说韩语，即使第二个孩子并不想说韩语，而第三个孩子并不想学韩语。

13.C解析：文中第五段中讲到了over-learning的好处，就是可以让孩子们从容应对。

14.B解析：本题为词义推测题。根据上下文我们可知，作者认为也许我们人类很侥幸，上文提到的两种倾向会相互制衡，那么地球的温度就会保持目前的水平了。

15.D44．答案为D

从短文第三段可得知A、B、C选项都不符合作者的观点。MissJackson虽然不富有，却善解人意，令人尊重。

16.D

17.D参见第四段。

18.B解析：参见句子：Duringthepasttenyears，scientiststellusthatthetemperatureoftheworldhasdroppedalittle．

19.C

20.C解析：见原文最后一段。作者的感受是：在沙漠中狩猎不应独自一人，也不要一辆车。

21.B此题是对细节信息和词汇知识的考查。其中．关键词是gameofchess．．invented。了解试题和各选项中的关键词后，迅速略读文章，找出线索。第1段第1句提供了相关信息，

AnoldIndianstory．．．gameofchessinventedby．．．PrimeMinisterofKingShirham。然后用排除法将与之无关的A、C、D项排除。唯有B项中ancient与文中old意思接近，Indianofficial与Indian．．．

PrimeMinister意思接近，故B项是正确答案。

22.C

23.B解析：由最后一段可知。今年在旧金山海湾地区看到了65只鲸，去年是17只。所以今年大约是去年的三倍。

24.C解析：第二段和最后一段。第二段告诉我们Jack是谁，他的故事是什么。最后一段作者特意说明WalterMitty是一个做白日梦的人，并在最后一句强调，如今仍有人梦想着(dream强调不可能成功)轻松成功。选项C是正确的。

25.B解析：由大声朗读到默读是读书的性质发生变化，故选B。

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

27.A根据文章第二段所提供的信息以及第一段最后一句话，可以得出结论，B、C、D三项均与文章不符，只有A项是正确的。

28.B解析：参见文章第一句。

29.A水手们能感觉到鲸鱼的胃里有东西在动。A项是正确的。

30.B解析：文章介绍伞的历史。

31.C

32.B22．答案为B

favorite“特别喜欢的人/物”；popular“受欢迎”；favorable“赞许的”；considerate“体贴的”。

33.B

34.C解析：本题为词义辨析题。remark意为“评论”；tell意为“告诉”；discuss意为“讨论”；argue意为“争论”。本句大意为：不要在孩子面前讨论喜欢或不喜欢那种食物。

35.C解析：本题测试运用介词的能力。本题中与介词搭配的是被其他词修饰的mornings，根据语法规则应该用On，这与词组inthemorning中的用法不同。

36.D解析：这篇文章告诉考生考试时应当注意什么。你学习很努力，终于到了考试的这一天了。

37.D

38.A解析：人们要看有线电视就得付钱。inorderto表示“为了……”；soasto表示目的，并且要放到句末。

39.B

40.Ctakeone’Sfirststep指“迈出第一步”。

41.A25．答案为A

从前文可知人们希望穿制服的人(专业人士)能提供高质量的服务。superior“高等的，高于的”；inferior恰恰相反，表示“下等的，差的”。

42.C解析：insistedondoingsth．坚持做某事。Insistedonmyleaving中的leaving为动名词，my动名词的逻辑主语。衣帽间的服务员坚持要我把自己的腿留在后面。

43.C21．答案为C

本题为词汇题，要求正确选择词义。A商务，业务，B文化，C支持，D信息。美国之音VOA的广播开始于第二次世界大战期间，与此同时德国正在利用无线电广播以获得国际(舆论)的支持。

44.C

45.D说某种语言的人数可以估计，但人们掌握语言的程度就很难估计了，所以用impossible。

46.A解析：前面说ShirleyAllen喜欢唱歌、弹钢琴，并且学的就是音乐。所以她的梦想肯定是钢琴家或歌手。选项A是正确的。

47.A解析：本题属逻辑题。前一句已经提示了。

48.C解析：本题属词选题。前文中的“theycouldleavesignsdeliberately…”已提示答案。

49.A解析：helpedinthekitchen意思是“帮厨”，与其后的Weplannedandcookedfor45peoplehotmeals…意思相吻合。

50.D解析：我在想，等到今天的孩子们达到我的年龄的时候，电视节目会是怎样的。

51.A

52.B

53.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。

54.C

55.B

56.C暂无解析，请参考用户分享笔记

57.D解析：画线部分读[c:]，其他选项的画线部分读[α:]。

58.D解析：画线部分读[ei]，其他选项的画线部分读[i]。

59.D

60.B画线部分读[n]；其他选项的画线部分读[in]。

61.D

62.D解析：本题测试名词辨义。award意为“奖品”；medal意为“奖章”；prize意为“奖品、奖章”；reward意为“报酬、回报”。本句大意为：公司奖给他一辆轿车奖励他对公司的贡献。

63.D

64.A解析：使役动词make用在被动句中其后的不定式不省略to。

65.C在定语从句中，all做先行词，连接词用that。句意为：在成功的路上，我所需要的就是你的帮助。

66.C解析：本题属复合式的比较级用法考查题。“than”表示前后比较，且carefully是复合式单词，故应用morecarefully。所以选C。

67.B这里是主谓一致问题。定冠词+姓氏复数表示所有家庭成员，当其作主语时，谓语动词用复数。从句中的谓语动词用的是过去时，主句中的谓语动词也应用表示过去的时态。选项B是正确的。【句子大意】早报来时，史密斯一家正在用早餐。

68.C本题测试固定搭配。want后接动名词表示“需要……”，此时主动结构舍有被动含义，need也有同样用法。本句大意为；我的头发要理了，但研究项目使我一直很忙。

69.B表示“本来不该……”。

70.A解析：本题测试名词辨义。crime意为“触犯法律的罪行”；sin意为“违反道德戒律的行为”；offence意为“冒犯的行为”；fault意为“过错”。结合句意，应选A。本句大意为：警察的职责是阻止和侦破犯罪，而法庭的职责是惩罚犯罪。

71.A

72.C解析：challenge在此意为“反驳”。

73.C

74.C

75.Dasif似乎。你看起来好像一个星期都没吃东西了。

76.B解析：for是并列连词，且其引导的并列句不放在句首；while意为“在……期间；虽然；但是，而”，不符合逻辑；since有“既然”之意，引导原因状语从句，符合题意，故选B项。

77.A本题考察倍数的表示方法。常用句型是(1)倍数+asmany／much…as；(2)倍数+比较级+than；(3)倍数+the名词+of。

78.D解析：本题考非限制性定语从句的用法。根据句意，故D项正确。本句大意为：一些金属比其他金属的导电性能要好。这说明前者的原子中比后者含有更多的自由电子。

79.Apotential“潜在的”；unknown“不可知的”：secret“秘密的”；unlimite“无限制的”。根据题干，可知A项是正确的。句意为：“这个国家很小，但它潜在的能源却很丰富。”

80.B解析：原句应表达为IrecognizedheratthemomentwhenIsawher.故排除C、D两项，forthemoment意为“暂时，目前”，不符合语境；themoment意为“一……就……”，引导时间状语从句。
