一个简单句跟在一名词或代词后(先行词)进行修饰限定，所以叫做定语从句。以下是定语从句知识点的重点内容，请考生学习掌握。

一、疑问句中考查定语从句

1. Is this the farm ________ you visited last week?

A. where B. the one C. on which D. /

【解析】答案是D。

命题人经常利用疑问句的特殊结构来干扰学生的正确选择。遇到这类定语从句时，最好的办法是先把疑问句还原成陈述句，然后判断谁是先行词，再看关系词在定语从句中所充当的成分，最后确定正确答案。

二、倒装句中考查定语从句

2. We came to a place, ________ stood a big tower.

A. which B. that C. / D. where

【解析】正确答案是D。为了保持句子平衡，句子用了倒装语序。倒装的使用使定语从句的结构变得较为特殊，因此对于使用倒装语序的定语从句，应先把倒装语序还原成正常语序，这样句子结构就比较清晰了。

三、拆分词组和固定搭配

3. The second is connected with the use ________ the body makes of food.

A. of which B. where C. to do D. that

4. Why can't you realize the part ________ they have played in our life?

A. which B. on which C. when D. where

【解析】正确答案分别是D和A。一些词组和搭配被拆开后，句子的含义就变得难以理解。首先把拆开的词组复原是理解此类定语从句的关键。上述句子中包含以下词组：make use of, play a part (in)。

四、添加插入语或状语

5. The scientist has made another discovery, _______ I believe is of great importance.

A. that B. / C. which D. why

【解析】应选择C。这类句子主要利用插入语或状语的添加来增加试题的难度。常见的插入语有：I think (suppose, expect, believe, imagine), in my opinion, to tell you the truth等。做这类题目时，最佳的办法是先删去插入语或状语，这样句子的主干部分就一目了然了。

五、插入非谓语动词

6. Is this the man ________ you want to have ________

the radio for me?

A. who; repaired B. that; repaired

C. whom; repairing D. that; repair

【解析】D项正确。非谓语动词是英语中难度较大的语法项目之一，因而在定语从句中加入非谓语动词就成了学生最易失分的题目。对付这类题目最有效的办法就是将句子还原。如：我们可以把几个句子中的定语从句进行还原，还原后的句子应是：You want to have the man repair the radio for me.
