例如：1. A doctor is ________looks after people’s health. 医生是照顾人们健康的人
(先行词) （关系代词）

二．定语从句的用法
常用的关系代词有：who, whom, whose, that, which.。

关系代词在定语从句中用作主语、宾语、定语等。

定语从句中关系代词作从句宾语时可以省略，如：

关系代词作从句的宾语时,常用which或whom,较少使用that或who,而且常常省略。

如：

当关系代词紧跟在介词后面时,必须用which或whom,而当介词移到句尾时,则又可以使用that或who. 如：This is the room in which Miss Li once lived. = This is the room that Miss Li once lived in.
常用的关系副词有：when, where, why 等。
