1.—He must be busy doing his homework right now.

—I imagine____.

A. that B. to C. so D. it

选C。I imagine so=I think so,

2. Mary had promised to give me a ticket for tomorrow. She failed, ____.

A. either B. though C. but D. too

选B。结合上下文意思我们可以知道本题表示转折关系，先排除A、D;而but为并列连词通常放在句首或句子中间起连接作用。故选B。

3. When I got to the cinema, the film _____ for five minutes.

A. had begun B. has been on

C. has begun D. had been on

选D。电影开始了五分钟，for five minutes为一段时间要求谓语动词要用延续性动词，故A和C先排除，而从句的动作发生在主句动作之后。

4.---I wonder why Mr Green hasn’t showed up at the meeting yet.

---I’m not sure, but he _______ in a traffic jam driving here.

A. could be stuck B. might stuck

C. might have been stuck D. must have stuck

选C。表示对过去已经发生事情的推测应该用情态动词的完成时形式，但might的可能性不大;结合上下文的意思可以知道应该用被动形式。

5.We have moved into a four-room flat so far. Our room is between _____.

A. Mary’s and Helen’s B. Mary and Helen’s

C. Mary and Helen D. Mary’s and Helen

选A。由句子的意思可以知道这里表示两人各自的房间。

6.With the development of science and technology, people’s life _______ in the past few years.

A. improved B. has improved

C. is improving D. had improved

选B。根据句子后面的时间状语in the past few years可以知道句子应该使用现在完成时。

7.Wang Wei is one of many Chinese students _______ “on the go’.

A. who lives life B. who live life

C. that lives living D. that live living

选B。 “one of +名词/代词“接定语从句时，先行词是前面的名词或代词，而不是one,因此可以排除A和C;再根据live用作及物动词时一般要接同源宾语live (a happy/ sad/poor, etc.) life，因此选B。其中on the go可以看着是相当于形容词的短语作定语。

8.There are a lot _______ people today than yesterday.

A. of B. more C. most D. /

选B。本题容易选A。因为许多学生很快会联想到a lot of短语。其实，只需要仔细看完句子就会发现句子的后面有than,暗示要选比较等级，而比较级前面用a lot来加强语气。

9.The TV set he _________ works well now.

A. has repairing B. having repaired

C. has been repaired D. has had repaired

选D。本题考查学生综合能力。首先要知道he________是定语从句，对先行词The TV set进行修饰。由于the TV set在定语从句中作宾语，所以可以省略关系代词that或which。而定语从句中有have sth done结构，即文章的句子为：The TV set that/ which he has had repaired works well now.主句为The TV set works well now.

10.Lei Feng is always ready to help others when they are in trouble and he never _______ their request.

A. turns up B. turns over C. turns in D. turns down

选D。本题考查短语动词的区别。turn up的意思是“将音量调高”、“出现，露面“;turn over意思是“打翻，移交;翻身”;而turn in表示“上交”;turn down表示“将音量等调低或拒绝”的意思。结合上下文的意思应该选D。
