3、关系词(Relatives)

1 Relative Pronouns（关系代词）: who , whom, which, that, whose, as
2 Relative Adverbs（关系副词）: when, where, why
关系词的作用：
1、指代作用：指代先行词；
2、连接作用：连接主从句；
3、成分作用：在从句中充当成分
The man who lives next to us sells vegetables.

四．限制性定语从句和非限制性定语从句
1限制性定语从句对先行词起修饰限定作用,常和先行词紧密相连
2 而非限制性定语从句是对先行词起补充说明作用, 非限制性定语从句中，先行词与定语从句往往有逗号隔开,非限制性定语从句相当于并列句、状语从句, 非限制性定语从句不能用that来引导, 非限制性定语从句常常用来修饰整个句子
如：I want to see this man, who can speak English.
He gave up the plan, which was a very good one.
I met John, who told me the news.
I will take this one, which seems to be the best one.
He has two sons, who work in the same company.
