　　定语从句引导词省略有以下几种情况。

1、在非正式文体中，用于指人的关系代词who whom, that 指代先行词在定语从句中作宾语时通常可以省略；用于指物的关系代词which和that指代先行词在定语从句中作宾语时中也通常省略。例如：

2）Where is the book (which/that) I bought last week?

2、 关系代词指代先行词在定语从句中作表语时，只用that ，它既可以指人，也可以指物，但时常省略。例如：

1）He is no longer the man that he used to be.

2）This is no longer the dirty place (that) it used to be.

3、以the way为先行词的`限制性定语从句，如果先行词way在定语从句中做状语，通常以in which或 that 引导，但在非正式文体中，人们通常省略in which或 that 。例如;

1)The way (in which) he spoke to us was suspicious.

2)I don’t like the way (that) you laugh at her.

4、以place为先行词的限制性定语从句，如果先行词place在定语从句中做状语，通常以where 引导，但在非正式文体中，人们通常省略where。例如：

1）This is the place (where) we met yesterday.

5、以reason为先行词的限制性定语从句，如果先行词reason在定语从句中做状语，通常以why引导，但在非正式文体中，人们通常省略why。例如：

1）That is the real reason(why) he did it.

6、以time,day,week,month,year等为先行词的限制性定语从句，如果先行词在定语从句中做状语，通常以when引导，但在在某些句型和某些时间状语中，人们通常省略when。例如：
