从三级考试对定语从句的测试来看，主要考查的是介词的选择。"介词 + which/whom"主要有以下几种情况：

A. 介词是句中短语搭配的一部分，如1）和8）：

1）Before her marriage, she spent a considerable time in that very part of Shanghai,she belong.（1998.6）

A.Which

B.to where

C.to which

D.at which

答案：C

（"属于"要用belong to，关系代词在句中作宾语，同时定语从句以介词结尾，因此把介词提前，形成to which she belong的结构。 ）

8）The grass______many animals live is abundant here.（2003.4）

A.by which　B.with which　C.on which　D.of which

答案：C

再如：

We need a chairman ______.

A.for whom everyone has confidence

B.in whom everyone has confidence

C.who everyone has confidence of

D.whom everyone has confidence on

答案：B

（表示"信任某人"要用have confidence in somebody，所以作定语，应该用a chairman in whom … has confidence.）

B."部分 + of + 整体名词"的结构，该结构作关系词也就是 "部分名词 + of which/whom"的结构。

该结构的使用应注意两点，一是注意定语从句与并列句的分别，如：

5）The United States is composed of fifty states,

A

two of those are separated from the others by land or water.

B　C　D

（2000.6）

答案：B

再如：

He invited many scientists to his birthday party, many of ______ were his old classmates.

A.whom

B.them

C.which

D.that

答案：A

这里很自然地会有many of whom 与many of them的选择。

C.在大多数情况下，要看关系词与先行词之间的关系，以确定选择什么样的介词，如10）：

10）The seventeenth century was one which many significant

A

advances were made in both science and philosophy.（2003.11）

B　C　D

答案：A

④ 注意as引导的非限制性定语从句的用法

as引导非限制性定语从句时，可置于句首，也可置于句尾，表示"正如……".如9）：

9）______is known to all, too much smoking will cause lung cancer.（2003.11）

A.That

B.It

C.As

D.What

答案：C

再如：The British are not so familiar with different cultures and other ways of doing things,______ is often the case in other countries.

A.as

B.what

C.so

D.that

答案：A

______ might be expected, the response to the question was very mixed.

A.As

B.That

C.It

D.What

答案：A

一般as引导定语从句时，其先行词为整个主句。which引导非限制性定语从句，其先行词也可以是主句或主句中的一部分。

⑤ 注意先行词为时间、地点或原因时，关系词的选用。如果用when, where 或why，关系词在从句中应该是作状语，否则的话则应该用which/that等。如上面7）中：

7）I will not forget the ten years______we both spent in the little village.（2001.6）

A.when

B.during which

C.which

D.in which

[答疑编号10010614：针对该题提问]

答案：C

先行词作spent的宾语，只能用which.

再如：

I've never been to Beijing, but it is the place ______.

A.where I'd like to visit

B.in which I'd like to visit

C.I most want to visit

D.that I want to visit it most

答案：D

先行词在从句中visit的宾语，关系词不能用where，而只能是that/which.

⑥注意定语从句与同位语从句的区别。如：

There are signs ______ restaurants are becoming more popular with families.

A.that

B.which

C.in which

D.whose

答案：A

由于signs与后面的restaurants没有修饰和被修饰关系，所以whose不对，如果是定语从句，关系词代替signs，而从句中不需要该词。所以这里不是定语从句而是同位语从句，从句表示sign的内容。

再如：

The fact______ he does so in so short period of time challenges explanation.（2003.4）

A.why

B.that

C.what

D.which

答案：B

Would the news______ he failed to pass the exam bother you?（2003.4）

A.which

B.that

C.of which

D.on which

答案：B

⑦先行词为reason时,关系词用why,先行词为 the way时，关系词用that或in which.例如：

That is the reason______ Ann could not do her part of the job.（1992.6）

A.that

B.of

C.which

D.why

答案：D

In his latest article Tom criticize the way which the war

A　B　C

being handled.（1997.6）

D

答案：C

⑧ 定语从句中的插入语

有时候，在定语从句的先行词和谓语动词之间会插入一个小句或者一个副词短语，这样就会造成理解上的困难。我们在做题时只要把这些插入语删除，然后按照定语从句的语法规则去做就可以了。如4）、11）

4）This is the sportsman whom everyone says will win the

A　B　C

first prize at the Winter Olympic Games.（1999.6）

D

答案：B

11）Helen was much kinder to her youngest child than she was to the others,______ , [of course], made the others jealous.（2005.4）

A.who

B.what

C.that

D.which 语教
