Attributive Clause定语从句

一、定义

定语从句：修饰名词或代词的从句。换句话说，名词、代词后的从句叫定语从句。
先行词：被定语从句修饰的名词、代词、甚至词组或句子叫先行词。
关系词 ：引导定语从句的词叫关系词。
1关系代词：在定语从句中担任主、宾、表、定语成分
2关系副词：在定语从句中担任状语成分

关系词3个功能：
1. 连接功能（连接先行词与定语从句）；
2. 担任功能（在定语从句中担任主、宾、表、定、状语）；
3. 替代功能（在定语从句中代替先行词）。

关系代词在定语从句中充当
主语的是： who, that, which, as
宾语的是： who, whom, that, which, as
定语的是： whose, which

先行词是人时，关系代词是：who, whom, that, as
先行词是物时，关系代词是：which, that, whose, as

关系副词有：when (先行词为时间), where (先行词为地点), why (先行词为原因)
关系副词 = 介词 + which whom

定语从句 分为两种：限制性与非限制性。先行词与关系词之间无逗号隔开为限制性；有逗
号隔开则为非限制性，且 一般由which引导。

唯一可以置于先行词之前的定语从句由关系代词as 引导。

二、关系代词引导的定语从句
指人，在从句中做主语
(1) The boys who are playing football are from Class One.
(2) Yesterday I helped an old man who lost his way.
2. whom指人，在定语从句中充当宾语，常可省略。
(1) Mr. Liu is the person (whom) you talked about on the bus.

注意：关系代词whom在口语和非正式语体中常用who代替，可省略。

3. which指物，在定语从句中做主语或者宾语，做宾语时可省略
(1) Football is a game which is liked by most boys.

(1) This is the watch whichthat I am looking for. (T)

2. 若介词放在关系代词前，关系代词指人时 用whom，不可用who或者that；指物时用which，
不能用that；关系代词是所有格时 用whose

(2) The man whothat you talked with is my friend. (F)

(2) From the year whenin which he was going to school he began to know what he wanted when
he grew up.

难点分析
（一）只能用that 不用which
1．当先行词是anything, everything, nothing (something 除外), few, all, none, little, some 等代
词时，或者是由every, any, all, some, no, little, few, much 等修饰时
(1) Have you taken down everything that Mr. Li has said?
(2) There seems to be nothing that seems impossible for him in the world.
(3) All that can be done has been done.
(4) There is little that I can do for you.
注意：当先行词指人时，偶尔也可以用who
(4) Any man thatwho has a sense of duty won’t do such a thing.
2. 当先行词被序数词修饰
(1) The first place that they visited in London was the Big Ben.
3. 当先行词被形容词最高级修饰时
(1) This is the best film that I have seen.
4. 当形容词被the very, the only, the last修饰时
(1) This is the very dictionary that I want to buy,
(2) After the fire in his house, the old car is the only thing that he owned.
当先行词指人时，偶尔也可以用who
(3) Wang Hua is the only person in our school who will attend the meeting.
5. 当先行词前面有who, which等疑问代词时
(1) Who is the man that is standing there?
(2) Which is the T-shirt that fits me most?
6. 当先行词既有人，也有动物或者物体时
(1) Can you remember the scientist and his theory that we have learned?

只能用which, who, whom不用that
1. 关系代词直接放在介词后面时，要用which，不用that； 要用whom，不用who。
2. 引导非限制性定语从句时，要用which, who, whom, 不 用that，也不能省略。

（二）关系代词as和which 引导的定语从句
as和which引导非限制性定语从句，有相同之处也有不同之处。具体情况是：
1．as和which都可以在定语从句中做主语或者宾语，代表前面整个句子。
(1) He married her, aswhich was natural.
(2) He was honest, aswhich we can see.
2. as引导非限制性定语 从句，可放在主句之前，或者主句之后，甚至可以切割一个主句；
which引导的非限制性定语从句只 能放在主句之后。另外，as有“正如……，正像……”的

意思
(1) As is known to all, China is a developing country.
(2) He is from the south, as we can see from his accent.
(3) John, as you know, is a famous writer.
(4) He has been to Paris more than several times, which I don’t believe.
注意：当主句和从句存在逻辑上的因果关系时，常用which
(5) Tom was always late for school, which made his teacher angry.
3. 当先行次由such, the same修饰时，常用as
(1) I have never heard such a story as he tells.
(2) He is not such a fool as he looks.
(3) This is the same book as I lost last week.
注意：当先行次由the same修饰时，偶尔也用that引导定语从句，但是和由as 所引导的定
语从句意思不同
(4) She wore the same dress that she wore at Mary’s wedding.
她穿着她在Mary婚礼上穿过的一条裙子。
(5) She wore the same dress as her young sister wore.
她穿着和她妹妹所穿的一样的裙子。

（三）以the way为先行词的定语从句通常由in which, that引导，而且通常可以省略。
(1) The way in which that. he answered the question was surprising.

（四） but 有时也可以做关系词引导定语从句
(1) There are very few but understand his idea. (but= who don’t )

（五）区分定语从句和同位语从句
1．定语从句修饰先行词，它和先行词是修饰关系；同位语从句说明先行词的具体内容，是
补充 说明的关系
(1) The plane that has just taken off is for London. 定语从句
(2) The fact that he has been dead is clear. 同位语从句
2．定语从句由关系代词或者关系副词引导 ，关系词在句中充当成分，有时可以省略；同位
语从句主要由that引导，在句中一般不做成分；句子 也可以由when, where, how, why, whether,
what等词引导，充当成分
(1) The news he told me is true.
(2) The news that he has just died is true.
(3) The problem that we are facing now is how we can collect so much money. 定语
(4) The problem how we can collect so much money is difficult to solve.
3. 同位语从句和先行词一般可以用be动词发展成一个完整的句子，而定语从句不可以

(2) The idea was that we could ask the teacher for advice.
(3) The fact that the earth moves around the earth is known to all. 同位语
(4) The fact is that the earth moves around the earth.
