英语定语从句中怎样用who，whom，whose，that，which

1、关系代词who的用法：

who的前行词必须是人，在从句中可以担任主语，往往也可以代替在从句中担任宾语的whom,但它的前面不能有介词，如果带了介词就必须用宾格whom（介词+whom）。

who, whom, that这些词代替的先行词是人的名词或代词，在从句中所起作用如下：

Is he the man who/that wants to see you? 他就是想见你的人吗？（who/that在从句中作主语）

He is the man whom/ that I saw yesterday. 他就是我昨天见的那个人。（whom/that在从句中作宾语）

2、Whose 用来指人或物，(只用作定语, 若指物，它还可以同of which互换）, 例如：

They rushed over to help the man whose car had broken down.那人车坏了，大家都跑过去帮忙。

3、which, that所代替的先行词是事物的名词或代词，在从句中可作主语、宾语等，例如：

A prosperitywhich / thathad never been seen before appears in the countryside.农村出现了前所未 有的繁荣。（which / that在从句中作主语）。

4、that代替关系副词

that可以用于表示时间、地点、方式、理由的名词后取代when, where, why和"介词+ which"引导的定语从 句，在非正式文体中that常被省略（正式文体中不可省略）。

例如：His father died the year (that / when / on which) he was born.他父亲在他出生那年逝世了。

定语从句
定语从句（Attributive Clauses）在句中做定语，修饰一个名词或代词，有时也可以修饰部分或整个句子。
被修饰的名词,词组或代词即先行词。定语从句通常出现在先行词之后，由关系词（关系代词或关系副词）引出。
关系代词有：who, whom, whose, that, which，as 。
关系副词有：when, where, why ,how 。
关系代词和关系副词放在先行词和定语从句之间，起连接作用，同时又可做定语从句的一个成分。当关系代词做宾语时可以省略。
定语从句中的谓语动词必须在人称上和数量上和先行词保持一致。
定语从句分为限制性定语从句和非限制性定语从句。
1 、关系代词引导的定语从句
1）who, whom, that
这些词代替的先行词是人的名词或代词，在从句中所起作用如下：
Is he the man who/that wants to see you?（who/that在从句中作主语）
He is the man whom/ that I saw yesterday.（whom/that在从句中作宾语）
2) Whose 用来指人或物，(只用作定语, 若指物，它还可以同of which互换),
例如：
They rushed over to help the man whose car had broken down. Please pass me the book whose (of which) cover is green.
3)which, that
它们所代替的先行词是事物的名词或代词，在从句中可作主语、宾语等，例如：
A prosperity which / that had never been seen before appears in the countryside.（which / that在句中作宾语）
The package (which / that) you are carrying is about to come unwrapped. (which / that在句中作宾语)
关系代词that和which 都可以指物，that 和Who 都可以指人，其用法区别：
1）不用that的情况
a) 在引导非限定性定语从句时
(错) The tree, that is four hundred years old, is very famous here.
b) 介词后不能用
We depend on the land from which we get our food.
c)多用who 的情况
①关系代词在从句中做主语
A friend who helps you in time of need is a real friend .
②先行词为those , people 时
Those who were either fools or unfit for their offices could not see the cloth .
③先行词为all, anyone , ones , one 指人时
One who doesn’t work hard will never succeed in his work .
④在There be句型中
There is a stranger who wants to see you .
⑤在被分隔的定语从句中
A new teacher will come tomorrow who will teach you German .
⑥在有两个定语从句的句子中，其一用who,其二用that,但若先行词后接两个以上的并列定语从句时，后一个必须重复前一个关系代词。
The student who was praised at the meeting is the monitor that is very modest and studies very hard .
There is a teacher who is always ready to help others and who enjoys what he does .
2) 只能用that作为定语从句的关系代词的情况
a) 在不定代词，如：anything, nothing, everything, all, much, few, any, little等作先行词时，只用that，不用which。
All that is needed is a supply of oil.
Finally, the thief handed everything that he had stolen to the police.
b) 先行词有the only, the very, the just修饰时，只用that。
He is the very man that helped the girl out of the water .
c) 先行词为序数词(the last)、数词、形容词最高级时，只用that。.
The first English book that I read was “The Prince and the Pauper” by Mark Twin .
d) 先行词既有人，又有物时。
He talked about the teachers and schools that he visited .
e)当主句是以who 或which 开始的特殊疑问句时，用that 以避免重复。
Who is the person that is standing at the gate .
f)关系代词在从句中做表语
He is not the man that he used to be .
2 、关系副词引导的定语从句
关系副词可代替的先行词是时间、地点、方式或理由的名词，在从句中作状语。
1)when, where, why，how
关系副词when, where, why,how的含义相当于"介词+ which"结构，因此常常和"介词+ which"结构交替使用，例如：
There are occasions when (on which) one must yield.
Beijing is the place where (in which) I was born.
Is this the reason why (for which) he refused our offer?
I’m surprised the way how (by which) he works out the problem .
注意：
①在非限制性定语从句中，"介词+ which"结构不能代替关系副词。
如：They set up a state for their own , where they would be free to keep Negroes as slaves .
②含有介词短语的动词一般不能拆开，介词仍放在动词后面。
Is this the book which (that) she was looking for ?
3、名词/数词/代词 /形容词最高级 + 介词 + 关系代词引导定语从句
She has written a book , the name of which I have forgotten .
There are fifty-five students in our class , all of whom are working hard .
There are five continents in the world , the largest of which is Asia .
4、 as, which 引导非限定性定语从句的差别：
由as, which 引导的非限定性定语从句，as和which可代整个主句，相当于and this或and that。As一般放在句首，which在句中。
As we know, smoking is harmful to one's health.
The sun heats the earth, which is very important to us.
as可引导非限制性从句，常带有'正如'的意思。
As is know, smoking is harmful to one's health.
用法区别：
(1) as 引导的定语从句可置于句首，而which不可。
As we all know , he never smokes .
(2) as 代表前面的整个主句并在从句中作主语时，从句中的谓语必须是系动词；若为行为动词，则从句中的关系代词只能用which.。
(3)非限定性定语从句中出现expect , think , suppose 等表示猜测、想象、预料等时。
She succeeded in her doing the research work , as we expected .
(4)As 的用法 the same… as；such…as 中的as 是一种固定结构, 和……一样……。
I should like to use the same tool as is used here .
We should have such a dictionary as he is using .

在定语从句中，关系代词who (whom) 和that都可指人和物，在一般情况下，可以互换使用，但在下列情况下值得注意：
一、用who (whom) 而不用that的情形
(1) 在非限制性定语从句中的先行词指人时，只能用who (whom)。
(2) 当定语从句对指人的先行词进行隔位修饰时，只能用who (whom)。
(3) 当先行词为people和those时，只能用who (whom)。
(4) 当先行词为one, ones, anyone, everyone, none, all(指人) 时，只能用who (whom)。
(5) 先行词指人，而关系代词在从句中作主语时，一般多用who。
(6) 在there be句型中名词的定语从句多用who (whom)。
(7) 当句子中有两个指人的现行词分别带有两个定语从句时，若一个定语从句的引导词为that, 那么，另一个定语从句的引导词必定为who。
二、用that 而不用who (whom)的情形
(1) 当先行词前面有形容词的最高级或序数词修饰时，引导词只能用that。
(2) 当先行词前面有only, some, any, no, every, little, few, much, all, very形容词修饰时，引导词只能用that。
(3) 当主句是以who开头的特殊疑问句时，引导词只能用that。
在定语从句中，关系代词which和 that都可指物，一般情况下，可以互换使用。但在下列情况下值得注意：
A. 只能用that而不能用which的情形
(1) 当先行词为：all, little, few, much, none 及 some-, any-, no-, every- 与 thing 所组成的复合单词时，只能用that。
(2) 当先行词前面有only, some, any, no, every, little, few, much, all, very等形容词修饰时，只能用that。
(3) 当先行词由形容词的最高级或序数词修饰时，只能用that。
(4) 当先行词同时包括人和物时，只能用that。
(5) 当先行词在定语从句中作表语时，只能用that。如：

This is a book that I have been looking for since last week. 这就是那本自上周以来我一直在寻找的书。

(6) 当主句是以which开头的特殊疑问句时，只能用that。如：

Which is the picture that you drew yesterday? 你昨天画的那张画是哪一张？

B. 只能用which而不能用that的情形

(1) 当非限制性定语从句中的先行词指物时，只能用which。如：

The pencil-case, which I bought last week, is missing. 那个铅笔盒，我上周买的，现在不见了。

(2) 关系代词前面有介词时，只能用which。如：

The tree under which we used to take a rest has been cut down. 我们过去常在下面休息的那棵树已砍刀了。

(3) 先行词为代词that或that所修饰时，只能用which。如：

I don’t take that which is too expensive. 我不要太贵的那一个。

whose
关系代词在从句中作定语表示所属关系，先行词是人，表示“先行词这个人的…”，用whose；先行词是事物，表示“先行词这个事物的…”，用whose…或the…of which或of which…都可以。

这几个词都可以引导定语从句，that什么时候都可以用。who,whose,whom区别主要在于它的意思上，who表示谁在从句中做主语，whom是它的宾格，在从句中做宾语，whose是谁的，它所代替的应该是一个物主代词或有名词所有格，例如：The girl who helps me is my sister.who做的是help的主语； The girl whom I help is my sister.whom 做的是help 的宾语；The girl whose bag is red is my sister.whose 代替的是the girl's.
The woman who (that) is speaking to my teacher is my mother.
The woman whom my teacher is talking with is my mother.
The woman whose girl is my classmate is my teacher.
