1.We keep in touch _____ writing often。

　　A. with B. of C. on D. by

　　解析：许多同学根据 keep in touch with(与....。.保持联系)这一搭配推断出此题应选A。但是选A错了，因为套此搭配此句意思不通，正确答案应是D，by 表示方式，bywriting 意为"通过写信"，全句意为"我们通过经常写信保持联系"。

2。We all regarded the poor old man ____sympathy。

 A. as B. with C. of D. by

　　解析：许多同学一看到句中的 regard 和选项中的 as，马上就联想到 regard ... as...(把....。.看作....。.)这一搭配，从而断定此题应选A。错了，原因是将此搭配套入原句，句子意思不通。正确答案是B，句意为"我们大家都很同情这位老人"。

3. -Mr. Wang， whom would you rather _____ the important meeting？

　-Tom。

　　A. have attend B. have attended

　　C. having attend D. have to attend

　　解析： 若将疑问句改为陈述句，就是I would rather have Tom attend the important meeting. 其中would rather后必须接动词原形，have sb. dosth。是"要某人做某事"。所以选A。

4.-What do you think made Mary so upset？

　　- _____ her new bike。

　　A. As she lost  B. Lost　C. Losing　 D. Because of losing

　　解析：将答句补全，就是 _____ her new bike made Mary soupset，显然，只能选C，用动名词短语作主语。

5. Before the operation， the doctor had to talk to the patient inorder to remove her fear ______ she might die during the operation。

　　A. when B. that C. which D. so that

　　解析：从两个分句之间的关系判断，没有因果关系，可先排除so that；由于第 2 个分句中不缺少句子成分，又排除了定语从句即选项A和C，只有B为最佳答案。fear之后的that引导同位语从句，对fear的内容进行补充和说明。

6. -English has a large vocabulary， hasn't it？

　　-Yes. _____ more words and expressions and you will find it easierto read and communicate。

　　A. Know B. Knowing C. To know D. Known

　　解析：因为第二个and后面是一个句子，所以前面也必定是一个句子，但前面这个句子没有主语，只能选用动词原形，构成一个祈使句，因此，正确答案是A。

7. There are eight tips in Dr. Roger's lecture on sleep， and one ofthem is：_____to bed early unless you think it is necessary。

　　A. doesn't go B. not to go C. not going D. don't go

　　解析：此题很容易选B，认为是用不定式作表语。其实，冒号已经表明后面是Dr.Roger讲的原话，这原话应当是个句子，只有选D才构成一个否定形式的祈使句。

8. Mr. Smith used to smoke _______ but he has given it up。

　　A. seriously B. heavily C. badly D. hardly

　　解析：因为指烟瘾或酒瘾很重，要用heavy或heavily，所以要选B。此外，雨雪下得"大"、烟雾"浓"、交通"拥挤"、波涛"汹涌"等，也用heavy。

9. Charles Babbage is generally considered ______ the first computer。

　　A. to invent B. inventing

　　C. to have invented D. having invented

　　解析：考生头脑中有considerdoing这一思维定势，易误选D，而题干用了被动语态，为动词不定式作主语补足语的结构。因不定式动作发生在谓语动作之前，用了不定式的完成式，故最佳答案为C。

10.He wrote five novels， two of _____ translated into English。

　　A. it B. them C. which D. that

　　解析：此题很容易误选答案C，以为后面是非限制性定语从句。事实上，translated是过去分词，而不是谓语动词，后面不是句子，无需连词，所以正确答案是B。若在translated前加上were，weretranslated就是谓语，这时就选连词which了。

11.If an excellent Chinese novel is translated into English， _____means many more people in the world can enjoy it。

　　A. as B. which C. what D. that

　　解析：因为前句已经有连词if，所以选答案D，that指前句所述内容。若没有if，就选B，which引导一个非限制性定语从句。

12. _____ is known to everybody， light travels much faster than sound。

　　A. It B. As C. That D. What

　　解析：此题选B，as引导一个非限制性定语从句，先行词是后面整个句子。若将逗号改为that，就选A，it是形式主语，that引导主语从句；若接着又在that前加上一个is，则应选D，what引导的是主语从句，that引导的是表语从句。

13.I agree with most of what you said， but I don't agree with_____。

　　A. everything B. anything C. something D. nothing

　　解析：此题很容易误选B，因为这是个否定句。若选B，I don't agree with anything。就等于I agreewith nothing (of what you said)，这就与前一分句的意思发生矛盾了。正确答案应该是A。

14. I don't mind drop in at your house when in town._____， the walk will do me good。

　　A. Sooner or later B. Still C. In time D. Besides

　　解析：根据句意，第二个分句表示递进关系，用Besides。故最佳答案为 D。

15. It is the ability to do the job _______matters not where you come from or what you are。

　　A. one B. that　 　 C. what D. it

　　解析：去掉题干中的not where you come from or what you are，题干即为是一个简单句：Theability to do the job matters. 把主语The ability放在强调结构中，即变为题干，显然最佳答案为B。
