父母是孩子最好的老师；2.

父母的言行影响孩子；

参考答案

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

2.B解析：theeducationsystem是主语，谓语动词应用单数；thedesiredresults意为“期望的结果”。

3.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。

4.A

5.D

6.D

7.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。

8.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。

9.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。

10.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。

11.B

12.A【句子大意】新打字机的价格是二手货的三倍。

13.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。

14.B

15.B解析：本题考查动词固定搭配的用法。deprive后常接介词of，表示剥夺什么。

17.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。

18.B

19.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。

20.C解析：much用在句中修饰比较级better。

21.D

22.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。

23.A本题考查祈使句型：

【应试指导】句意：Mary，到这里来，其余的人待在原处。根据句子的结构可判断出这是个祈使句。所以要用动词原形开头。Mary在句中不是

主语，而是“呼语”。

24.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。

31.Ainparticular是固定搭配，意为“特别地”。

32.C

33.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。

34.C

35.A

36.B解析：此处是对将来情况的假设。虚拟条件句的谓语部分为should，had或were时，可把if省去，而把should，had或were放在从句的主语之前，构成主谓部分倒装。

37.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。

38.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?

39.D

40.B

41.B解析：cuts“裁减”；shortages“短缺”；weaknesses“弱点”；imports“进口”，故正确选项为B。

42.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。

43.D解析：本题测试形容词辨析。四个选项的意思分别是“普通的”，“清楚的”，“正义的”，“仅仅的”。根据句意，D项正确。本句大意为：他仅仅把它作为一个细节来描述，而我却认为它是这个计划中最重要的部分。

44.C

45.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。
