完整版定语从句总结精辟

1. 定语从句 : 1） 定语从句的定义

在复合句中， 修饰名词或代词的从句叫做定语从句。被定语从句所修饰的词叫先行词。引导定语从句的词叫关系词。关系词包括关系代 词 who （宾格 whom,所有格 whose ）,that, which 和关系副词 where, when, why 等。

The boy who is wearing a black coat bought a dictionary yesterday.

The noodles that （ which ） my mother cooked were delicious.

The school where I learned judo was very large.

I remember the day when our band was formed.

I don 'tknow the reason why she got so angry this morning.

2） 定语从句的种类 ：定语从句可以分为限定性定语从句和非限定性定语从句。

（1）限定性定语从句： 它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。 这种从句与主句的关系十分密切， 书写时不可用逗号分开。如果关系代词在限定性定语从句中作宾语，关系代词通常可以省略。

Do you know the girl who just came in?

Shanghai is a city (that ) I 've always wanted to visit.

Her sister married a man (who/whom/that) she met on a plane.

The time when I first met Mr. White was a very difficult period of my life.

（2）非限定性定语从句：它只是对先行词作附加补充说明，如果去掉，主句的意思仍然清楚完整。这种从句与主句的关系不是很密切，书写 时往往用逗号分开。非限定性定语从句一般不用 that 引导，而且不可以省略关系词。

The old woman, who lives on her own, has a cat for company.

Lori is going to marry Mark, whom she does not love.

Beijing, which is the capital city of China, is a very beautiful city.

3） 关系代词的用法： 在定语从句中， 关系代词起着连接主句与从句，指代先行词和在从句中作句子成分的三重作用。关系代词的选用取 决于主句中的先行词以及关系代词在从句中作何种成分。

一． 关系代词 who, whom 的用法

（1） who 可以代替人（即它的先行词必须是人） ，在从句中担任主语，往往也可以代替在从句中担任宾格的

介词，如果带介词则必须用宾格 whom ，即“介词 +whom ” E.g. Jonny is a person who always has novel ideas. The girl who the first prize in the contest is from Zhejiang.

The person who/whom you just talked to is Mr. Depp.

---The person to whom you just talked is Mr. Depp. ( 介词 to 提到定语从句前，只能用 whom.) We 'll go to the hospital to see the patients, most of whom are children.

(whom 前常用表示数量的词 none/neither/both/each/all of …)

(2)

在定语从句中，who, that 指人时可以通用，但在下列情况下用 who,而不用

that.

A) 先行词是 one, ones, anyone 时，宜用 who.

One who has nothing to fear for oneself dares to tell the truth.

The ones who flatter me don 'tplease me. Anyone who fails to finish the task given should be criticized.

B) 先行词为 those 时，宜用 who. Those who want to go to the Great Wall sign up here.

No words are strong enough to express our thanks to those who worked hard to rescue survivors in the earthquake.

C) 当先行词有较长的后置定语时，宜用 who.

I met a girl in the street yesterday who grew up in Yunnan province.

D) 一个句子中带有两个定语从句时，其中一个定语从句的关系代词时

is the group leader who studies very hard.

E) 在 there be 开头 的句子中，事宜用 who.

There is a young man who wants to see your father. There was a king who was kind to his people.

There are many old men who are against this plan. 二．关系代词 whose 的用法： 关系代词 whose 是关系代词 who 的所有格形式，它 既可以代人，也可以代物。当 whose 代物时，相 当于 of which. Whose 引导的定语从句既可以是限定性定语从句，也可以是非限定性定语从句。

Do you know Peter whose father happens to be working in your company?

The tourist wanted to book a room whose window faces south.

=The tourist wanted to book a room the window of which faces south.

=The tourist wanted to book a room . The room 's window faces south.

whom,但它的前面不能有

Anyone who laughs last laughs best. that ， 另一个宜用 who. E.g. The boy that you met last night

We went to see our teacher Miss Styles, whose husband lost his life in the earthquake.

Xi 'an, whose walls remain as good as before, is one of the few cities with city walls. 三．关系代词 that, which 的用法

(1)在限定性定语从句中指代物时， which 和 that 一般可通用。

The new house that/which I has just bought is about six miles away. They planted some trees that /which didn 't need much water.

(2) 限定性定语从句中只用 that 而不用 which 的情况。

A )先行词有形容词最高级修饰时

This is the best way that has been used against pollution.

Polly is the most direct young woman that I have ever come across .

B) 先行词有序数词修饰时

This is the third time that they have met.

The very first time that Lester saw the film, he made up his mind to become a doctor.

C)主句已有疑问词 who 或which 时

Which of the car s that are in front of the hotel belongs to you?

Who is the man that is sitting by the lake ?

D) 先行词既有人又有物时

He talked about the schools and teachers that he had visited.

The bike and his rider that had run over an old man were taken to the police station.

E) 先行词为 all, much, few, little, something, everything, anything, nothing, none 等不定代词时 It 's easy to do the repair. All

that you need is a hammer and some nails.

We haven 't got much that we can offer you. I 'd like to tell you something that will make you surprised.

F) 先行词前面有 the very, the only, the same, any, few, little, no, all, one of 等词修饰时

This is the very room that I slept in that evening.

The only thing that we can do is to give you some money.

Li Ming is the only one that wants to be a teacher.

G) 有两个定语从句，其中一个关系代词以用 which, 另一个宜用 that

Edison built up a factory which produced things that had never been seen before.

(3) 只用 which 而不用 that 的情况

A) 引导非限定定语从句时

The fish, which I bought this morning, is very fresh.

My house, which I bought two years ago, has got a lovely garden.

Jim passed the driving test, which surprised everybody in the office.

Helen was much kinder to her youngest son than to others, which , of course, made the others envy him.

The factory produces half a million pairs of shoes every year, most of which are sold abroad. (which 前常用 none/neither/most/both/each/all/a little of 等词修饰 )

B )在限定性定语从句中，关系带词前有介词时

I was put in a position in which I had to accept I was less important.

This is the hotel in which you will stay.= That 's the hotel （which/that ） you will stay in.

（此句中，如果介词in 放在句子的后面，那么关系代词既可用 which,也可用that ，还可省略。

C ）在限定性定语从句中，如果有两个定语从句时，其中一句的关系代词

that 时，另一个用which. Let me show you the novel that I borrowed from the library which was newly open to us. 4) 关系副词的用法( where, when, 子成分。由于关系副词在从句中均做状语， 一．关系副词

where 的用法：

where 在从句中作地点状语。 The hotel where we stayed was very clean.= The hotel (that/which) we stayed at was very clean.

=The hotel at which we stayed was very clean. I got to the stage where I wasn 't coping any more.

why ）： 关系副词和关系代词一样，具有数重作用。连接主句与从句，指代先行词，在从句中作句 所以具体选用什么关系副词，主要取决于关系副词在从句中充当什么类型的状语。 有关系副词 where 引导的定语从句，其先行词主要是表示地点的名词，如 building, city, room 等，

=I got to the stage (which/that) I wasn 't coping with any more.

= I got to the stage with which I wasn 'tcoping any more.

二．关系副词when 的用法：有when 引导的定语从句，其先行词主要是表示时间的名词，如间

状语。

time, day, date,等,when在从句中作时

I'll never forget the time when we first met in London .

=I'll never forget the time during which we first met in London.

The date (when/that) he joined the ANC Youth League was August 5th.(如果按语法来讲，上例中的定语从句只能用when引导，但在口语中，常用that 代替when, 而且还可以省略。)

三．关系副词why 的用法：由why 引导的定语从句，常用在先行词reason 后面，why 在句中作原因状语。

The reason why I got a job was that I worked

hard.

=The reason (that)/for which I got a job was that I worked

hard.

The reason why she was late was that she missed her plane.

=The reason (that)/for which she was late was that she missed her

plane. Amy didn 'tget a pay rise, but this wasn'tthe main reason why

she left.

=Amy didn 'tget a pay rise, but this wasn'tthe main reason (that)/for which she left.

(一般说来，在定语从句中，只要先行词是the reason，它的关系副词就是why,但在口语中，和when 一样，why常被that代替，也可省

略。)

重点比较：带reason 的定语从句与表语从句的常用句型：

定语从句表语从句The reason why/that …；…the reason why/that …The reason is that…(不能用why，否则就重复了)

I know the reason why she studies so

well.

The reason is that he is always careless in his work.

四．关系代词和关系副词引导的定语从句的区别

对于同一个先行词，正确区分关系代词和关系副词，关键是要弄清楚它们在定语从句中担任什么成分，而不仅仅取决于先行词是什么。如果关系词在从句中制作主语或宾语，就是关系代词；如果关系词在定语从句中做状语，就是关系副词，当然上面提到的口语用法除外。例句比较： 1. This is the college (that/which) I visited.

2. This is the college where I studied three years

ago.

3.I'll never forget the day(that/which)we spent

together.

4.I'll never forget the day when I got married.

5) 使用定语从句注意事项

定语从句中的主谓一致

A)定语从句中的关系代词作主语时，从句谓语的人称，数要与先行词一致。

Is he the man who/that wants to see you?

B) as/which 作主语引导非限定性从句指全句时，从句谓语用第三人称。

Liquid water changes to vapor, which is called

evaporation.

As is usual, Hans came to school late this morning.

C) 先行词为“ one of +复数名词“时，关系代词为从句主语，谓语用复

数。

Freddy is one of the students who want to be diplomats in our class.

D)先行词为“ the only one of the+复数名词“时，关系代词为从句主语，谓语用单数。

He is the only one of the students who has been a winner of scholarship for three

years. 二. what, how 不能用于定语从句中．

A) what不能用作关系代词来引导定语从句，但是what引导的宾语从句可以与that引导的定语从句进行互换。

Tell me anything (that) you know. Tell me what you know.

Tell me anything what you know.( wrong)

B) how 不能用作关系副词来引导定语从句，修饰表示方式的way 的定语从句用which 来引导，也可用that 或省略。

This is the way (in which/that) I worked out the

problem.

This is how I worked out the problem.

This is the way how I worked out the problem. (wrong)

三．关系代词和关系副词的省略

1)关系代词的省略：A) 非限定性定语从句中关系代词不可以省略。

Jan Hasek, who was my former English teacher, retired last year. B) 在限定性定语从句中，关系代词用作动词宾语时可省略。 Sorry, forgot to bring the magazine (which/that) you want.

C) 关系代词作介词宾语时，如果介词出现在关系代词前，关系代词不可以省略；如果介词位于定语从句句末，关系代词可以省略。 This is the government building in which my father works.

This is the government (which/that) my father works in.

This is the government building in my father works. ( 错误 )

D) there be 句型之后的定语从句中，做主语或宾语的关系代词常客省略。

There 's nothing (that) I can do about it.

6)定语从句和同位语 的区别

A) 根据 that 在从句中是否做成分来判定。引导定语从句的 that 是关系代词，在句中充当主语或宾语，是对先行词的一个说明。引导 同位语从句的 that 是连接词，不充当任何成分，不能省略，也不能用 which 代替。同位语从句用来说明名词或代词表示的具体内容。 The news that you told me last week is not true.

（that 引导的定语从句，说明是哪一个 news, that 在从句中充当 told 的宾语。 ） The news that the leader will come here is not true.

(that 引导的同位语从句，说明 news 的具体内容， that 在从句中不担任任何成分 )

B )根据意思来判断

在关系代词前加 is 后，如果句子成立就是同位语从句，否则就不是。

The news that you told me is not true.

---The news is that you told me last week. （ 不成立；不是同位语从句。 ） The news that the leader will come here is not true.

---The news is that the leader will come here. （ 成立；是同位语从句 ）
