定语从句分类.doc

定语从句 限制性与非限制性定语从句 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限制作用；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割开。非限制性定语从句相当于并列句、状语从句等。如： I want this man, who (=for he) can speak English. He gave up the plan, which (=though it) was a very good one. I met John, who (=and he) told me the news. I will take this one, which (=for it) seems to be the best one. He has two sons, who work in the same company. (He has only two sons.) He has two sons who work in the same company. (Perhaps he has more than two sons.) 非限制性定语从句中关系代词和关系副词的用法 关系代词和关系副词在任何情况下都不能省略； Who（主语），whom（宾语），which（主语、宾语）不能用that代替，也不能互相替换； 介词+which/whom+从句结构中，介词不能移到从句的后面； when, where可用于非限制性定语从句。 关系代词的用法 关系代词的作用和分类 1、关系代词的作用有三个： 连接作用：关系代词引导从句，把它和主句连接起来； 替代作用：关系代词在从句中替代它前面的先行词； 成分作用：关系代词在从句中总是充当句子成分。 2、关系代词的用法分类 关系 代词格 从句 关系 代词 格 用于限制性定语从句和非 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 关系代词的用法与分类有三点依据： 根据所引导的从句的限制性和非限制性； 根据所替代的先行词是指人还是指物； 根据它在从句中所充当的成分----主语、宾语、表语或者定语。 关系代词that和which的用法 限制性定语从句中，必须用关系代词that的情况： 当先行词是不定代词all, much, little, something, everything, anything, nothing, the one时。如： Do you have anything that you want to say for yourself? You should hand in all that you have. 当先行词前面被the only, the very, any, few, little, no, all等词修饰时。如： This is the very person that I’m waiting for. The only thing that we can do is to give you some money. 当先行词是形容词最高级或者先行词的前面有形容词最高级修饰时。如： This is the best that has been used against pollution. This is the most interesting film that I’ve ever seen. 当先行词是序数词或它前面有序数词修饰时。如： This train is the last that will go to Suzhou. What is the first American film that you have seen? 当先行词既有人又有物时。如： Do you know the things and persons that they are talking about? 当主句的主语是疑问词who或which时。如： Which is the bike that you lost? Who is the boy that won the gold medal? 有两个定语从句时，其中一个关系代词也在从句中作表语时。如： They secretly built up a small factory, which prod
