定语从句所修饰的词 叫先行词。 定语从句放在先行词后面。定语从句分为限定性定语从句和非限定性定语从句。本章只介绍限定性定语从句。引导定语从句的词有关系代词that、which、who、 which、 whose和关系副词where 、when，关系代词和关系副词是引导词， 在定语从句中担当某一成份。

关系代词和关系副词的作用：

先行词指物时， 关系代词用that 或which(在句中作主语或宾语)。

如：China is a country which / that has a large population.

先行词指人时， 关系代词用(who)作主语或宾语，whom (作宾语)，whose (作定语)，that (作主语或宾语)。 如：

注意：下列情况下关系代词只用that 而不用which 或 who。

先行词是指物的不代词，如：all, little, few, much, none, anything, nothing, everything等时。如：I didn’t understand the words all that he said.

先行词由最高级、序数词以及any, very, only, all, no, just 等所修饰。如：This is the most beautiful place that I have been to .

行词既包括人，也包括物。如：They always like to talk about the man and the things that they see on the road.

当主句是以which 或who 开头的特殊疑问句时。如：who is the man that opened up the lab.
