一．什么叫定语从句

在复合句中，修饰某一名词或代词的从句叫定语从句。定语从句有限定性从句和非限定性从句。在初中阶段多为限定性从句。被定语从句修饰的词叫先行词，定语从句放在先行词后面，关系代词或关系副词放在先行词和定语从句之间，起连接作用，同时也可作定语从句的某个成分。引起定语从句的关系代词有that, which , who , whom ,whose 和关系副词where when why等。

二．定语从句中关系代词的用法

1.当先行词是不定代词all, much等时，或者被这些词修饰时，只能用that引用定语从句。例：I’ve read all the books that my mother bought for me .我已经读完了妈妈给我买的所有的书。

2. 先行词被序数词或形容词最高级修饰时，只能用that引导定语从句。例：This is the most exciting movie that I have ever seen .这就是我曾经看过的最有趣的电影。

3.先行词被the only , the last, the same, the very修饰时，只能用that引导定语从句。例如：This is the only book that was written by him .这就是唯一一本他写的书。

4.先行词既指人又指物时，只能用that引导定语从句。例如，They are talking about the school and the teachers that they visited yesterday .

5. 当关系代词前介词时，只能用which引导定语从句。例如：This is the house of which the windows face south.这是那所窗户朝南的房子。

6. 非限定性定语从句只能用which引导定语从句引导。例如：Football, which is a very

interesting game, is played in many countries.很多国家都在踢足球，他是很有趣的运动项目。

7.先行词是that，those时，只能用which引导定语从句例如：What’s that which was put in the car ?

五．关系代词who, whom, that 的用法区别（先行词指人）

1. 在who开头的疑问句中，若出现定语从句修饰指人的先行词时，只能用that引导从句。例：Who is the boy that is wearing a red coat over there?

2. 先行词是those, one 等指人的不定代词，定语从句用who引导。例：We should help those who are in trouble .

3. 先行词是人且介词提前紧跟先行词之后时，只能用whom,引导定语从句。例如：This I the boy with whom I played tennis .
