定语从句 在复合句中，修饰名词或代词的从句叫做定语从句。 被定语从句修饰的词叫先行词，引导定语从句的词叫关系词。分为关系代词和关系副词。 限制性与非限制性定语从句 （一）限制性定语从句与非限制性定语从句的区别 限制性定语从句对先行词起修饰作用；而非限制性定语从句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，状语从句等。 Eg. I want 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. He has two sons who work in the same company.(Perhaps he has more than two sons) He has two sons, who work in the same company.(He has only two sons) 非限制性定语从句中关系代词和关系副词的用法 1.关系代词和关系副词任何情况下都不能省略； 2.who(主语），whom(宾语），which(主语，宾语）不能用that 代替，也不能互相替换。 3.介词+ which \whom +从句结构中，介词不能移到从句的后面。 4.when， where可用于非限制性定语从句。 关系代词的用法 关系代词的用法分类 从句 关系代词 格 用于非限制性定语从句 只用于限制性定语从句 指人 指物 既指人又指物 主格词 who which that 宾格词 who(m) 属格词 whose/of whom whose/of which whose 关系代词that 和which的用法口诀： that,which可互换，下列情况勿照办。 关系代词这一伙，全用that准没错； 先行词前有修饰，千万不要用which； 要用which别着急，介词提前逗隔离； 疑问人物一which，当然还是用that。 1.下列情况下只能用that （限定性定语从句） （1）当先行词是不定代词 all , much ,little , something , anything , none , the one 时 Eg: It is better than anything that we have ever seen . 当先行词被no , the only , the very 修饰时 Eg: This is the very book that i am looking for . 当先行词是形容词最高级或先行词的前面有形容词最高级修饰时或有序数词修饰时 Eg: This is the best way that has been has been used against pollution . It is the first dog that he gave to me . 关系代词有：who , whom , that , which , whose , as 等 who ， whom 指代人，who 做主语、宾语, whose只做宾语。Which 指物，做主语、宾语、和表语。 that和whose 既可以指人也可以指物，that做主语，宾语和表语，whose做定语=of which = of whom 注：关系代词代替先行词在定语从句中做主语，宾语，表语，定语，因此定语从句不能再出现关系代词所代替的名词或代词。 eg : The film that/which we saw it yesterday is interesting . ( ) The film that/which we saw yesterday is interesting . ( ) 关系代词作主语时不能省略 eg : The number of people who/that lost homes reached as many as 2,5000 . 关系代词作表语时可以省略 Eg: Where is the man who/that/whom I saw this morning ? 关系代词作表语时可以省略 She is not the girl that/she was . 他不在是从前的那个女孩了。 当先行词既有人又有物时 Eg: Do you know the things and persons t
