语言知识
1.Which of the following italicized parts explains PURPOSE?(B)
A. He is such an honest man that we all believe in him.
B. Please open the window so that we can breathe fresh air.
C. I returned home in a hurry, only to find my house broken into.
D. He had so little education that he was unfit for this job.
解析：such…that．．．与so…that．．．均表示“如此……以至于……”，引导结果状语从句，故排除A、D。当so与that连起来用时，即so that．．，表示“以便／为了……”，引导目的状语从句，B为正确答案。C中的only to作结果状语，一般表示出乎意料的结果。
2.\\(B)
A. the woman who is cleaning the floor…
B. the woman who will clean the floor…
C. the woman who has been cleaning the floor…
D. the woman who has cleaned the floor…
解析：本题考查现在分词作定语的用法。现在分词作定语一般表示“主动”和“进行”。四个选项都是主动语态；A、C是进行体，正是现在分词定语的含义。D是现在完成时，有“过去的动作但对现在有影响”之义，也是现在分词定语的含义。只有B是一般将来时，与现在分词的含义不一致。如果要把B改为非谓语形式的定语，应该用不定式。故答案是B。
3.Professor Wang is going to give us a lecture on the history of American literature, but when and where ______ yet.(B)
A. aren’t decided
B. hasn’t been decided
C. haven’t decided
D. haven’t been decided
解析：句末的yet提示此处需要完成时态，且这里的时间和地点应视为一个整体．要用单数形式的完成时被动语态，故选B。
4.If you have really been living in France for so many years, it’s about time you ______ able to talk with people in French.(D)
A. must be
B. are
C. be
D. were
解析：习惯用法。it is(about)time(that)是一个虚拟语气句型，谓语动词用一般过去式或“should+动词原形”(较少见，且should不可省略)，答案为D。
5.He ______ have been nervous because he didn’t go straight in.(B)
A. ought to
B. must
C. should
D. had to
解析：考查情态动词的用法。“must+完成时(或完成进行时)”是对过去事实一种较为确定的推测．表示过去某时刻必定发生的事。ought to／should+have done表示“本应该做某事却没有做”，与句意不符。had to“不得不”，不符合题意。因此B为正确选项。
6.This research project requires more money than ______.(D)
A. being put in
B. have been put in
C. to be put in
D. has been put in
解析：than作连词引导比较分句的用法。than作连词时，既有连接主句和分句的作用，又充当从句中的主语，如：He bought more things than was needed．题中比较分句的主语是money．因此谓语动词用第三人称单数形式，答案为D。
7.Some researchers believe that there is no doubt______ recycling saves energy and raw materials, and reduces pollution.(B)
A. which
B. that
C. what
D. whether
解析：句子结构分析题。名词doubt“怀疑”后的同位语从句用whether连接，如：There is somedoubt whether he can recover from the serious disease．在no doubt“不怀疑”之后的同位语从句用that连接。答案为B。
8.It is clearly stated on the bulletin that ______ throws the rubbish away at will will be punished.(D)
A. whenever
B. who
C. anyone
D. whoever
解析：这是一个复合句。句中it是形式主语，真正主语是that引导的从句，而that从句中又含有主语从句，此处应填入一个引导词引导该主语从句且在句中充当主语，符合这一要求的只有D。
9.______ I’m willing to help, I do not have too much time available.(D)
A. Even
B. As long as
C. As
D. While
解析：引导让步状语从句的连词用法。while引导让步状语从句时，意义相当于although，但while让步分句通常位于句首，选D。even“甚至”是副词，不能连接句子；as long as“只要”表条件，与句意不符：as可以引导让步状语从句，但句子要用倒装。
10.This computer programming is ______ to any of the others we have ever had.(A)
A. superior
B. more superior
C. the most superior
D. the more superior
解析：be superior to意为“优越于……，比……好”，该短语本身就表示比较级，因此不需要再用表比较含义的more或most进行修饰。答案为A。
11.It is necessary that something urgent______ to combat smuggling.(B)
A. is done
B. be done
C. has to be done
D. must be done
解析：考查虚拟
