Unit 25 Attributive clauses Contents 引导定语从句的词就叫做关系词。根据关系词的用法不同，关系词又分关系代词和关系副词，其中关系代词有that, which, who, whom, whose, as, but等，关系副词有where, when, why等。关系词既起连接先行词与定语从句的作用，又做从句中的某个句子成分。 This is the book that my father bought me yesterday. 这就是我父亲昨天帮我买的那本书。 句中修饰 the book 的 that my father bought me yesterday 就是定语从句；被定语从句所修饰的the book这是先行词；代表the book的关系代词that在定语从句中作bought的直接宾语。 The time when he arrives is not known. 他到达的时间还不知道。 句中when he arrives是定语从句，被定语从句修饰的the time是先行词，关系副词when作时间状语。 Look at activity 1 Read P161-162 关系代词的一般用法 先行词是人，在从句中作主语用who，作宾语用whom或who，作定语用whose；先行词是物，在定语从句中作主语或宾语都用which，作定语用of which或whose均可。在限制性定语从句中which, who, whom都可用that代替。关系代词作宾语时常被省略。 This is the man who helped me yesterday. 这就是昨天帮助我的那个人。(作主语) The teacher (who/whom/that) you want to see is coming. 你要见的老师来了。see的宾语，可省略 I met a boy whose father was a astronaut. 我认识一位男孩，他的父亲是宇航员。(作定语) Here is the coat which/that will be made to you. 这是一件做给你的衣服。（作主语） This is the factory (which/that) we visited last year. 这就是我们去年参观的那家工厂。(作visited的宾语，可以省略) He has a book whose cover (=the cover of which) is very beautiful. 他有一本封面非常漂亮的书。 关系副词的一般用法 关系副词有when, where, why，在定语从句中作状语，分别表示时间、地点和原因。when的先行词通常是time, day, season, age, 等时间名词；where的先行词通常是place, city, town, village, house, situation等地点或情形名词；why的先行词只能是reason。关系副词when和where有时可用“介词＋which”代替，why可用for which代替。 Beijing is the place where (=in which) I was born.　 北京是我的出生地。 Is this the reason why (=for which) he refused our offer?　 这就是他拒绝我们帮助他的理由吗？ Read P162-163 限制性定语从句和非限性定语从句 “限”是先行词不可缺少的定语.若省去，主句意思不完整或不明确；“非限”是插入成分只是附加的解释说明的作用。 This is the house we bought last year.
