人生不是上帝为谴责我们的缺陷而给我们布下的陷阱。人生也不是一场拼写比赛，不管你拼出多少单词，一旦出现了一个错误，就会前功尽弃。人生更像是一个棒球赛季，即使最好的球队也会输掉三分之一的比赛，即便最差的球队也有春风得意的日子。我们的目标就是多赢少输。当我们能够接受不完整是人性的一部分这个事实时，当我们的人生不断滚动并能欣赏其价值时，我们就会获得其他人仅渴望的完整人生。我相信这就是上帝对我们的要求：不求“完美”，不求“永不犯错”，而是求得人生的完整。

;2.实际上淡水是短缺的;3.我们应当怎么办。

参考答案

1.Ainparticular是固定搭配，意为“特别地”。

2.B

3.A解析：句意：她昏倒了。给她脸上浇些水，或许她会醒过来。本题考查词组辨析。comeround：过访，绕道而来，苏醒过来；comeback：回来，恢复；comeagain：再说一遍，重复一遍；comeout：出来，传出。

4.B

5.D解析：上句责备玛丽应该做作业而不是坐到那儿看电视，下句是玛丽对妈妈责备的一种辩解：“你说过电视是有教育意义的。”所以D项正确。

6.A【句子大意】新打字机的价格是二手货的三倍。

7.B

8.Blaunch为“发射”讲；其余为干扰项。

9.B考查反义疑问句。原句应是：youwouldthinkhehadhaveforgotten…反义疑问句的规则是陈述部分是肯定式，疑问部分应是否定式。Wouldthink表示推测，疑问部分也应选择would。选项B是正确的。【句子大意】你难道还认为他已经忘掉了，是吗?

10.A解析：shape意为“(女人的)姿态，身段”；form意为“形状，形态”；appearance意为“外表，样子”；body意为“身体”。由题意知应选A。

11.A

15.C解析：副词so置于句首，句子应该用倒装语序，某人受伤用sb.beinjured来表示，故答案为C。

16.B解析：表示否定的副词前置于句首，句子需要不完全倒装，即助动词提前。其余选项均可排除。除Notuntil外还有never，seldom，rarely，seldom，no，little，hardly，innotime等否定副词或结构放在句首时，句子需要部分倒装。

17.A

18.A解析：favor：帮助，一般用domeafavor；good：好处；help不与do搭配：kindness：善良。故选A。

19.D解析：本题考查动词搭配。doone'shomework“做作业”；makemistakes“犯错误”。句意为：做作业，还要保证别犯错误。

20.D

21.C

22.C解析：句子的前半部分是主语从句，主语从句中的谓语动词时态应根据句意而定。

23.B

24.A解析：反问疑问句的陈述部分是肯定式时，疑问部分用否定式。以letme或letus起始的反问疑问句，疑问部分用willyou或won'tyou，所以选项A是正确的。

25.C

26.B

27.A

28.C解析：much用在句中修饰比较级better。

29.C

30.D解析：which修饰非限定性定语从句，指代前边一句话。本题涉及句法知识——简单句、并列句和复合句。例如：Hehastwodaughters.Theyaredoctors.(简单句)Hehastwodaughtersandtheyaredoctors.(并列句)Hehastwodaughters,whoaredoctors．(复合句)

31.Bsetout意为“出发，动身”。

32.B

33.D

34.A解析：本题考虚拟语气在名词性从句中的用法。在“ask(advise，desire，ordersuggest，require，etc。)+the广引导的从句中，谓语动词应用“should+认”，should可以省去，再结合语态，故A项正确。本句大意为：他们要求所有的必要文件都必须在月底之前交到校长办公室。

35.A解析：根据上文提到“findone”，故下文中也应填one，表示泛指。

36.C解析：本题考查词义的辨别。rise出现，put放下，raise提起，arise升高。

37.C

38.D

39.C解析：notonly…butalso连接主语时，谓语动词根据就近原则由butalso后的成分来决定。TomandMary是两个人，所以动词用复数形式。

40.D

41.D

42.C

43.D解析：从句中的问句主谓不倒装。从句的时态随主句。我想知道那辆车的价格。

44.C解析：本题考查倒装虚拟语气用法。本句是表示与将来事实相反，所以从句用wereto形式。句意为：如果他今天出发的话，他就会在星期五以前到达那里。

45.B解析：本题考查固定搭配。havetrouble(in)doingsth.“做某事有困难”。句意为：有时孩子们在分清故事和现实方面会有困难，相信故事中的事确实存在。

46.Dapplyto应用；applyfor申请

47.A本句考查两个并列句之间的连接的词。题干的意思是：“气球能够浮在空气中正如船能够浮在海面上一样。”在四个选项中，只有A项的justas有“正如，犹如”的意思。故选A。

48.A解析：此题考查反意疑问句的用法。主句为祈使句，因此其反意疑问句用willyou。

49.A解析：while意为“虽然”；as意为“因为”；if意为“如果”；since意为“因为”。根据题意选A。

50.B解析：本题考查固定搭配的用法。当否定词位于句前时，得出结论应用reach/achievein/arriveatconclusion，故选B。

63.C解析：结构衔接。whether和or搭配，意为“不管…还是…”，此处的句意为：无论对错，任何人都能说他们想说的话，故C项为正确答案。provided和if都不能与or搭配，可排除：either…or…意“不是……就是……”，表示在两种可能性中选择其一。

64.B解析：表示“每一天”有两种形式。一种是形容词形式，即everyday；注意，everyday是一个单词。另一种是副词形式，即everyday，注意是两个单词。这里，是用形容词everyday来修饰activities。

65.A

66.C解析：我回头想想自己的孩提时代。

67.D

68.D解析：本题属习惯用法题。下句中就有提示“namesfrom”。

69.D根据上下文，此处应为“在处理这场冲突的工作中”。
