初中英语语法—定语从句
定义：定语从句（Attributive Clauses）在句中做定语，修饰一个名词或代词。定语从句在句中的作用相当于形容词，所以又称为形容词性从句。被修饰的名词或代词即先行词。定语从句通常出现在先行词之后，由关系词（关系代词或关系副词）引出。
关系词 关系代词有：who, whom, whose, that, which
关系副词有：when, where, why
关系词作用：1起连接作用2替代作用3成分作用
Mary is a beautiful girl.
（形容词作定语）
Mary is a girl who has long hair.
（句子作定语，修饰girl,叫做定语从句。）
Mary is a girl who has long hair.
先行词 关系词
根据定语从句与先行词的关系,定语从句可分为限制性定语从句及非限制性定语从句。限制性定语从句紧跟先行词,主句与从句不用逗号分开,从句不可省去。非限制性定语从句主句与从句之间有逗号分开,起补充说明作用,如省去,意思仍完整。
This is the car which I bought last month.
The car, which I bought last month, is very nice.
一、关系代词（who, whom, whose, that, which）
1.当先行词指人时，用关系代词that/who在从句中作主语或宾语。whom在从句中作宾语。
如：The man who/ that gave a speech on TV is the president．
昨天在电视上演讲的人是总统。（作主语）
This is the strange man that/who/whom I met yesterday．
