必修一 M4 关系代词引导的定语从句 一.定语从句的基本概述 1.定语从句的定义：在复合句中修饰主句中某一名词或代词的从句叫定语从句，它所修饰的名词或代词叫作先行词。 2.关系词的作用：连接主句和从句; 指代先行词; 在从句中充当句子成分。 3.定语从句的分类：限制性定语从句，非限制性定语从句。 4.关系词的分类：关系代词：that，which, who，whom，whose，as 关系副词：when，where，why 二.关系代词的基本用法 关系代词替代指人或物的先行词并在定语从句中充当主语、宾语、定语等成分。 1.who指人，在定语从句中可以作主语或宾语。 e.g. Here comes the girl who wants to see you. 2.whom指人，在宾语从句中只做宾语，可省略，也可用who代替。 e.g. Rose is the person (whom/ who) you should look after. He is the man whom I saw yesterday. 3.whose指人或物，在定语从句中作定语。 e.g. They rushed over to help the man whose car had broken down. Please pass me the book whose cover is green. 1)先行词指人时，whose+n.=the +n.+ of whom =of whom the + n. 2)先行词指物时,whose +n.=the+n.+of which =of which the +n. e.g. The house, whose windows are broken, is empty. = The house, the windows of which are broken,is empty. =The house, of which the windows are broken, is empty. The doctor, whose name was Johnson, lived in a small town in the north of England. A teacher is a person whose duty is to teach. 4.which指物，在定语从句中作主语、宾语（一般可省略）、表语。 e.g. China is a country which has a long history. The package which you are carrying is about to fall. 5. that可指人或指物，在定语从句中作主语、宾语（一般可省略）或表语。指人时可用who替代，指物时可用which替代。 e.g. The number of people that/who come to visit this city each year reaches one million. The chair, (that/which) you broke yesterday is now being repaired. 【注意】关系代词替代先行词在定语从句中充当主语、宾语、定语或表语，因此定语从句中不能再出现关系代词所替代的名词或代词。 e.g. The book (that/which) you lent it to me yesterday is very interesting.
