定语从句归纳总结 一、定语从句的定义：
用来修饰名词或代词的从句叫定语从 句。被定语从句所修饰的名词或代词叫先行 词（antecedent）。定语从句一般是由关系 代词或关系副词来引导的。相当于名词和形 容词的作用。
3.This is the reason why(for which) he was late.

七、注意事项：
1、关系代词和关系副词在定从中的不同成分 a、This is the place where he works. This is the place which(that)we visited last year.
b、That was the time when he arrived.
eg: 1. Do you know the man who came to see Xiao Yang this morning?
2.The day is not far off when we will ks5u精品课件 make a trip to Britain.
二、关系代词和关系副词的作用：
如： a) What is the name of the tall woman who is standing there? 站在那边的那个女人叫什么名字? b) Toronto is a city (that) I' ve always wanted to visit. 多伦多是我常想去参观的一个城市。

4.关系代词whom在限制性定语从句中作宾语时可用 who代替whom，但在非限制性定语从句中作宾语时 不可用who来代替。 eg.This is the girl whom I met in the street. 这是我在街上遇到的女孩。 先行词the girl在限制性定语从句中作宾语，可用 who代替whom。 eg.A young man had a new girl friend, whom

eg. A five-year-old boy can speak two foreign languages, which surprises all
the people present.
一个五岁的男孩会讲两门外语，令所有在场的 人感到非常惊讶。 析：从语境可知，令所有在场的人感到惊 讶的内容是一个五岁男孩会讲两门外语这整个 一件事，因此先行词为整个主句，此时应由 which引导非限制性定语从句。

2．非限制性定语从句和主句关系不十分密切，只是对 先行词作些附加的说明, 如果去掉, 主句的意思仍然清 楚。这种从句和主句之间往往用逗号分开，一般不用 that引导。非限制性定语从句中，关系词不可省略。 如：
a) Rome, which is the capital of Italy, has a very long history. 意大利的首都罗马历史非常悠久。 b) Yesterday I met Professor King, who came from the University of London. 昨天我遇见金教授，他从伦敦大学来的。
g. The house which we live in is not large.
h. The house we live ks5u精品课件 large. in is not
八、限制性定语从句和非限制性定语从句
1．限制性定语从句是先行词在意义上不可缺少的 定语，如果去掉，主句的意思就不完整或失去意义。 这种从句和主句的关系十分密切，写时不用逗号分 开。限制性定语从句中作宾语的关系代词常可省略。
B.指物时，作介词的宾语，关系代词只能 用which
This is the question about whicห้องสมุดไป่ตู้ we’ve had so ks5u精品课件 much discussion.
五、关系副词when, where, why的用法
关系副词都等于一个适当的介词＋which， 在从句中作状语
When=in/at/on/…+which; Where=in/at/on/…+which; Why=for /…+which 1.Do you still remember the day when(on which) we went to visit the museum together? 2.This is the factory where(in which)my father once worked.
四、关系代词which和that的区别： A.关系代词必须用that的情形：
1、当先行词被形容词的最高级所修饰 This is the best film that I have ever seen. 2、当先行词被序数词修饰 The first car that arrived at the destination was driven by John. 3、当先行词被the only, the very等修饰
1、引导作用 2、替代作用 3、在定语从句中担当某个成分的作用
eg: 1.Those who want to go please sign your names here.
2.This is the house where he was born. 3. Bill, who was here yesterday, asked me a lot of questions. ks5u精品课件
2、关系代词放在介词后面，只能用which或 whom a.This is the boy with whom he worked. b.This is the boy whomhe worked with. c. This is the boy who he worked with. d. This is the boy he worked with. e. The house where we live is not large. f. The house in which we live is not large.
