英语定语从句用法详解

英语定语从句用法详解

在复合句中，修饰名词或代词的从句叫定语从句，被修饰的名词或代词叫先行词，引导定语从句的有关系代词who, whom, whose, which, that等和关系副词where, when, why等，关系代词和关系副词在定语从句中担任句子成份。

1.由who引导的定语从句中，who用作主语，如：This is the boy who often helps me.

2.由whom引导的定语从句中，whom用作宾语，如：The man whom you are waiting for has gone home.

3.由whose引导的定语从句中，whose用作定语，如：Do you know the girl whose skirt is white?

4.由which引导的定语从句中，which用作主语或谓语动词的宾语或介词的宾语，如：

The room in which there is a machine is a work shop.

The river which is in front of my house is very clean.

This is the pen which you want.

注意：

(1)whom, which用作介词宾语时，介词可放在whom、which之前，也可放在从句原来的位置上；但在含有介词的动词固定词组中，介词只能放在原来的位置上。如：He is the very person whom we must take good care of.

(2)引导非限制性定语从句时，必须用关系代词which，不用that,如：I have lost

my bag, which I like very much.

(3)关系代词在句中作主语时，从句的谓语动词的人称和数必须和先行词保持一致。

5.由that引导的定语从句中，that可以指人或物，在从句中作主语或谓语动词的宾语，但不能放在介词后面作介词宾语，如：

The book that I bought yesterday was written by Lu Xun.

注意在下面几种情况下必须用that引导定语从句。

(1)先行词是不定代词all, few, little, much, something, nothing, anything等，如：

All that we have to do is to practise English.

(2)先行词被序数词或形容词最高级所修饰，如

(3)先行词被all, any, every, each, few, little, no, some等修饰，如

I've eaten up all the food that you gave me.

(4)先行词被the only, the very, the same, the last修饰时如

He is the only person that I want to talk with.

(5)先行词既有人又有物时，如:

They talked about persons and things that they met.

(6)当句中已有who时，为避免重复，如：Who is the man that is giving us the

class?

6.由when, where, why引导的定语从句，如:

I don't know the reason why he was late.

This is the place where we have lived for 5 years.

I'll never forget the day when I met Mr Li for the first time.

注意：先行词是表示地点时，如果从句的谓语动词是及物的，就用that(which)，如果从句的谓语动词是不及物的，就用where引导。This is the house Which /that he has lived in for 15 years.(Where he has lived for 15 year.)

7. 限制性定语从句和非限制性定语从句

(1)限制性定语从句是句中不可缺少的组成部分，主句和从句之间不用逗号分开。引导非限制性定语从句的关系代词有who, whom, whose, which, of which等，这些关系代词都不能省略。

(2)非限制性定语从句是对主句先行词的补充说明，没有这种从句，不影响主句意思的完整，一般用逗号把主句和从句分开，关系代词用which,不用that;指人时可用who,如：I have two brothers, who are both students.

8．如何简化定语从句

（1）.定语从句简化为形容词或形容词短语作后置定语。如:

My grandfather lives in a village that is far away from here.

→My grandfather lives in a village far away from here.我祖父住在离这儿很远的一个村子。This is a book that is worth reading.

→This is a book worth reading. 这是一本值得看的书。

（2）定语从句简化为现在分词或现在分词短语作前置或后置定语。

The man who is standing under the tree is our English teacher.

→The man standing under the tree is our English teacher.

站在树下面的那个人是我们的英语老师。

I saw the house that was burning at that time.→I saw the burning house at that time.

当时我看到那房子在燃烧。

（3）定语从句简化为过去分词短语作后置定语。

I like to see the films which are directed by Zhang Yimou.→I like to see the films directed by Zhang Yimou. 我喜欢看张艺谋导演的电影。

She is the girl who was praised at the school meeting.→She is the girl praised at the school meeting. 她就是在校会上受表彰的那个女孩。

（4）定语从句简化为不定式作后置定语。

He is always the first person that comes to school.→He is always the first person to come to school.他总是第一个到校。

The report which will be given tomorrow is important to us.→The report to be given tomorrow is important to us. 明天要作的报告对我们很重要。

（5）定语从句简化为what 从句。

I couldn't remember the words that he said.→I couldn't remember what he said.

我记不得他说的话。

初中定语从句的用法和精练

一、定语从句的概念

在复合句中，修饰某一名词或代词的从句叫定语从句。被修饰的名词或代词叫先行词，定语从句一般放在先行词的后面。

The man who / that I saw at the school gate yesterday is my English teacher.

先行词定语从句

昨天我在校门口看见的那个人是我的英语老师。

二、定语从句的关系词

引导定语从句的关系词有关系代词和关系副词，常见的关系代词包括that, which, who(宾格whom，所有格whose)等，关系副词where, when, why等。关系代词和关系副词放在先行词及定语从句之间起连接作用，同时又作定语从句的重要成分。

①I am waiting for the boy who /that is wearing a red coat. （关系代词作主语）

先行词关系代词

我正在等穿着红色外套的那个男孩。

②The dictionary that / which my sister gave me last Sunday is very expensive.

先行词关系代词（关系代词作宾语）

我姐姐上周星期天给我的那本字典很贵。

③The woman whose name is Linda Brown is his mother. （关系代词作定语）

先行词关系代词

那个是他的母亲，名叫琳达?布朗。

④That is the house where my father used to live. （关系代词作状语）

先行词关系副词

那是我父亲曾经居住过的房子。

三、关系代词的用法

1. that 既可以用于指人，也可以用于指物。在从句中作主语或宾语，作主语时不可省略，作

宾语时可省略。例如：

① Mary likes music that is quiet and gentle. 玛丽喜欢轻柔的音乐。(that作主语)

② The coat (that) I put on the desk is blue. 我放在桌子上的那件外套是蓝色的。

(that作宾语)

2. which用于指物，在句中作主语或宾语，作主语不可省略，作宾语可省略。例如：

① The building which stands near the train station is a supermarket.

位于火车站附近的那座大楼是一家超市。(作主语)

② The film (which) we saw last night was wonderful.

我们昨天晚上看的那部电影很好看。(作宾语)

3. who, whom都用于指人，who用作主语，whom用作宾语。在口语中，有时可用who代替whom，也可省略。例如：

① The girl who often helps me with my English is from England.

经常在英语方面帮助我的那个女孩是英国人。(作主语)

② Who is the teacher (whom) Li Ming is talking to? 正在与李明谈话的老师是谁?

(作宾语)

小结：that—既可指人，也可指物，作主语，不能省略；作宾语，可以省略。

which—指物，作主语，不能省略；作宾语，可以省略。

who—指人，作主语，不能省略；作宾语（常用whom），可以省略。

注：当关系代词在定语从句中作主语时，定语从句的谓语动词形式由先行词定。

注意——

(1) 当定语从句中含有介词，介词放在句末时，who, that, which可省略，但介词在关系代词前时，只能用“介词+ which/whom”结构。例如：

① This is the house in which we lived last year. 这是我们去年居住的房子。

② Please tell me from whom you borrowed the English novel.

请告诉我你从谁那借的这本英文小说。

(2) 含有介词的固定动词词组中，介词不可前置，只能放在原来的位置上。例如：

This is the person whom you are looking for. 这就是你要找的那个人。

(3) that 作介词的宾语时，介词不能放它的前面，只能放在从句中动词的后面。例如：

The city that she lives in is very far away. 她居住的城市非常远。

(4) 关系词只能用that而不用which的情况：

a. 先行词被序数词或形容词最高级所修饰，或本身是序数词、基数词、形容词最高级时，只能用that，而不用which。例如：

He was the first person that passed the exam. 他是第一个通过考试的人。

b. 被修饰的先行词为all, any, much, many, everything, anything, none, the one等不定代词时，只能用that，而不用which。例如：

Is there anything that you want to buy in the shop? 你在商店里有什么东西要买吗?

c. 先行词被the only, the very, the same, the last, little, few 等词修饰时，只能用that，而不用which。例如：

This is the same bike that I lost. 这就是我丢的那辆自行车。

d. 先行词里同时含有人或物时，只能用that，而不用which。例如：

I can remember well the persons and some pictures that I saw in the room.

我能清楚记得我在那个房间所见到的人和一些照片。

e. 以who或which引导的特殊疑问句，为避免重复，只能用that。例如：

Who is the girl that is crying? 正在哭泣的那个女孩是谁?

f. 主句是there be 结构，修饰主语的定语从句用that，而不用which。例如：

There is a book on the desk that belongs to Tom. 桌子上那本书是汤姆的。

(5) 关系词只能用which，而不用that 的情况：

a. 先行词为that, those时，用which, 而不用that。例如：

What’s that which is under the desk? 在桌子底下的那些东西是什么?

b. 关系代词前有介词时,一般用which,而不用that.例如:

This is the room in which he lives. 这是他居住的房间。

c. 引导非限制性定语从句，用which, 而不用that。例如：

Tom came back, which made us happy. 汤姆回来了，这使我们很高兴。

五、关系副词的用法

(1) when指时间，其先行词表示时间，在句中作时间状语。例如：

This was the time when he arrived.这是他到达的时间。

(2) where指地点，其先行词表示地点，在句中作地点状语。例如：

This is the place where he works. 这是他工作的地点。

(3) why 指原因，其先行词是原因，起原因状语作用。例如：

Nobody knows the reason why he is often late for school.

没人知道他为什么上学总迟到。

定语从句典型错误例析

1. 我给他看了我上周在杭州的照片。

【误】I showed him the photos I took them in Hangzhou last week.

【正】I showed him the photos I took in Hangzhou last week.

【析】关系代词或关系副词既代替先行词，又在定语从句中充当一定的成分。

例句为省略了关系代词（that/which）的定语从句，that/which指代the

photos，在定语从句中充当took的宾语，故them多余，应去掉。

2. 那个正在修理汽车的人是我的叔叔。

【误】The man is mending the car is my uncle.

【正】The man who/that is mending the car is my uncle.

【析】关系代词在定语从句中充当主语时不可省略，只有作宾语时才能省略that。

本句还可以译为The man mending the car is my uncle.（-ing形式短语

mending the car作the man的后置定语。）

3. 这只风筝是你父亲昨天为你扎的吗？

【误】Is this kite your father made for you yesterday?

【正】Is this kite the one (that) your father made for you yesterday?

【析】若把this看作kite的修饰语，短语this kite为主句的主语，这时我们可以看出主句中缺少表语，即定语从句的先行词，所以应该加上代词the one。

如果我们把this看作代词，作句子的主语，那么kite应该为句子的表语，

则可以看出先行词kite前缺少定冠词the。故本句还可改为：Is this the kite

(that/which) your father made for you yesterday?

4. 她告诉我的就这些。

【误】This is all which she told me.

【正】This is all (that) she told me.

【析】当先行词为all, none, one, any, few, little, everything, anything, nothing等或先行词前有序数词，形容词最高级修饰时，关系代词只能用that。另外，

本句还可以译为This is what she told me.不过此时what引导的是表语从

句，而不是定语从句。

5. 这是我们明天要讨论的问题。

【误】This is the problem about that we’ll talk tomorrow.

【正】This is the problem about which we’ll talk tomorrow.

【正】This is the problem (that/which) we’ll talk about tomorrow.

【析】“介词+关系代词”引导的定语从句，先行词指人时，关系代词用whom；

指物时，关系代词用which。另外，有些固定短语如look after, listen to等，一般也不能将介词提到关系代词之前。

6. 他是今天早晨迟到的学生之一。

【误】He was one of the students who was late this morning.

【正】He was one of the students who were late this morning.

【析】在“one of+复数名词”结构中，定语从句的先行词是复数名词，故谓语动词应用复数；在“the only one of+复数名词”的结构中，定语从句的先行词是one，故谓语动词应用单数。如：She is the only one of the students in our class who has ever been to Beijing.她是我们班唯一去过北京的学生。

7. 我还记得我在北京度过的日子。

【误】I still remember the days when I spent in Beijing.

【正】I still remember the days (which/that) I spent in Beijing.

【析】定语从句中引导词的选择关键词是看先行词在定语从句中充当什么样的成分，或者说定语从句中缺少什么成分。如果从句缺少主语，表语，宾语，则引导词通常为which, that, who, whom, as；如果缺少定语则用关系代词whose；如果缺少状语，则用关系副词when, where, why.分析例句的成分可以知道，从句中缺少谓语动词spent的宾语，故应用关系代词which或that来引导定语从句。若把例句变为：I still remember the days ______ I enjoyed myself in Beijing。则定语从句中缺少时间状语，故此时应用关系副词when。

8. 昨晚送你回家的那个人是谁？

【误】Who is the man who sent you home last night?

【正】Who is the man that sent you home last night?

【析】当主句为含有who/which的疑问句，关系代词用that，而不用who或which。如：Which is the book that you bought yesterday?哪本书是你昨天买的？

9. 他们谈了许多他们所知道的人和事。

【误】They talked about a lot of things and persons what/who/which they knew.【正】They talked about a lot of things and persons that they knew.

【析】先行词既有人又有物时应该用that来引导。What不可以引导定语从句。

10. 我的家乡已不再是十年前的样子。

【误】My hometown is no longer the town which it used to be ten years ago.

【正】My hometown is no longer the town (that) it used to be ten years ago.

【析】当先行词在定语从句中充当表语时关系代词一般只能用that。另外，先

行词是there be中的主语时，关系代词也常用that，口语中这两中情况的关系代词that也可以省略。如：There is a park (that) we often visit on Sundays.

由于定语从句的结构和用法比较复杂，初学者在使用时往往容易犯一些错误，最常见的有如下五种：

一、在定语从句中加了多余的定语。

1．误：Some of the boys I invited them didn’t come．

正：Some of the boys I invited didn’t come．

译：我邀请的男孩中有几个没有来。

析：应删去them，因为从句的宾语是省略了的whom，who或that。

2．误：The book that you need it is in the library．

正：The book that you need is in the library．

译：你需要的书在图书馆里。

析：应删去it，因为从句的宾语是关系代词that。

二、把定语从句谓语动词的单、复数弄错。

1．误：Anyone who break the law will be punished．

正：Anyone who breaks the law will be punished．

译：任何违犯法律的人将被处罚。

析：应改break为breaks，因为who指anyone，是单数。

2．误：Those who has finished may go home．

正：Those who have finished may go home．

译：做完了的人现在可以回家。

析：应改has为have，因为who指those，是复数。

3．误：He is the only one of the teachers who know French in our school．正：He is the only one of the teachers who knows French in our school．

译：他是我们学校中唯一懂法语的人。

析：应改know为knows，因为one前有the only之类限定词，定语从句在意义上修饰的是the only one，是单数，而不是复数名词the teachers。

4．误：This is one of the rooms that is free now．

正：This is one of the rooms that are free now．

译：这是目前空着的房间之一。

析：应改is为are，因为one前没有the only之类的限定词，定语从句在意义上修饰的是名词复数the rooms，而不是单数one。

三、误省略了定语从句中作主语的关系代词。

1．误：Children eat a lot of sugar often have bad teeth．

正：Children who／？that eat a lot of sugar often have bad teeth．

译：吃糖多的孩子往往牙齿不好。

析：应加上关系代词who或that，因为从句少主语，且主语不能省略。 2．误：The key opens the bike is missing．

正：The key that／which opens the bike is missing．

译：开这辆自行车的钥匙不见了。

析：应加上关系代词that或which，因为从句少主语，且主语不能省略。

四、定语从句中加了多余的关系副词或介词。

1．误：The house where he lives in needs repairing．

正：The house where he lives needs repairing．

或：The house he lives in needs repairing．

译：他住的房子需要修理。

析：应保留where，删去从句中的in，因为关系副词where在从句中作地点状语，in属多余。或删去关系副词where，因为where在这里的意思是in which，否则介词in就重复了。

2．误：I still remember the day on when I first came to Beijing．

正：I still remember the day when I first came to Beijing．

或：I still remember the day on which I first came to Beijing．

译：我仍记得我第一次来到北京那天的情景。

析：应删去on，因为when在这里的意思是on which，否则介词on就重复了，或把when改为which。

五、在作先行词的时间名词或地点名词后错用了关系代词或关系副词。

1．误：I still remember the day when we spent together．

正：I still remember the day that／which we spent together．

译：我仍记得我们在一起度过的日子。

析：应改when为that或which，因为从句中谓语动词spent是及物动词，其后应跟宾语而不是时间状语。

2．误：This is the house where we lived in last year．

正：This is the house which／that we lived in last year．

译：这是我们去年住过的那个房子。

析：应改where为which或that，因为从句谓语动词lived后有介词in，其后少介词宾语，而不是地点状语。

初中英语定语从句的用法解析

初中英语定语从句的用法解析 【摘要】定语从句是一种形容词的关系从句。它由关系代词或关系副词引导（1）。初中英语中的定语从句仅限于限制性定于从句，但对初中生来说，定语从句既是一个重点，也是一个难点。 【关键词】定语从句先行词关系代词关系副词 一、英语中的定语从句与汉语中的定语位置不同。 在复合句中，修饰某一名词或代词的从句叫做定语从句。英语中的定语从句始终要放在被修饰的词之后，而汉语中的定语则放在被修饰词之前。如： The man who / that I saw at the school gate yesterday is my English teacher. 先行词定语从句 昨天我在校门口看见的那个人是我的英语老师。 二、英语从句中的句型结构比较复杂，有先行词、关系代词或关系副词。被定语从句修饰的词叫先行词，引导定语从句的关联词有关系代词或关系副词。限制性关系分句和它的先行项的所指意义有着不可分割的联系（2）。关系代词或关系副词放在先行词和定语从句之间起纽带作用，关系代词或关系副词在定语从句中要充当一个成分。关系代词在句中可作主语、宾语或定语，关系副词在句中作状语。如： I am waiting for the boy who /that is wearing a red coat. （主语） 先行词关系代词 我正在等穿着红色外套的那个男孩。 The dictionary that / which my sister gave me last Sunday is very expensive.(宾语) 先行词关系代词 我姐姐上周星期天给我的那本字典很贵。 The woman is his mother whose name is Linda Brown. (定语) 先行词关系代词 那个是他的母亲，名叫琳达·布朗。 That is the house where my father used to live.(状语) 先行词关系副词 那是我父亲曾经居住过的房子。 三、初中英语中的定语从句关系代词或关系副词的具体用法。 1. who指人（也可用that），在定语从句中作主语，也可作宾语。如： Yesterday I helped an old man who / that lost his way. （主语） 昨天我帮助了一位迷路的老人。 Mr Wang is the man (who / that / whom )you met in the zoo this morning.(宾语) 王先生就是今天早上你在动物里遇到的那个人。 注意：关系代词who指人,作宾语时，可用whom代替；作宾语时，关系代词可省略。作其它成分，关系代词则不能省略。 2. whose指人，也可指物。在定语从句中作定语。 The boy whose mother is ill is staying at home to look after her today. 其母亲生病的那个男孩今天呆在家里照顾她。 I have a story book whose cover is red. 我有一本封面是红色的故事书。 3. which指物（也可用that），在定语从句中作主语，也可作宾语。如： Football is a game which / that is liked by most boys. （主语） 足球是被大多数男孩喜欢的运动。 I don’t believe the news which / that Tom won the game.

(完整版)高中英语定语从句讲解及练习

高中英语定语从句讲解及练习 定语从句是高中重点知识，也是高考常考点，大家也不容易掌握，这篇文章主要教你关系代词引导的定语从句 关系副词引导的定语从句判断关系代词与关系副词限制性和非限制性定语从句等内容，有例题讲解定语从句在句中做定语，修饰一个名词或代词，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等。 关系副词有：when, where, why等。 18.1 关系代词引导的定语从句 关系代词所代替的先行词是人或物的名词或代词，并在句中充当主语、宾语、定语等成分。关系代词在定语从句中作主语时，从句谓语动词的人称和数要和先行词保持一致。 1）who, whom, that 这些词代替的先行词是人的名词或代词，在从句中作主语和宾语。例如： Is he the man who/that wants to see you? 他就是你想见的人吗？（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。 Please pass me the book whose （of which）cover is green.请递给我那本绿皮的书。 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 prosperity which / that had never been seen before appears in the countryside. 农村出现了前所未有的繁荣。（which / that在句中作宾语） The package （which / that）you are carrying is about to come unwrapped. 你拿的包快散了。（which / that在句中作宾语） 18.2 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、地点或理由的名词，在从句中作状语。 1）关系副词when, where, why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.任何人都有不得不屈服的时候。 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？ 2）that代替关系副词，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+which\"引导的定语从句，在口语中that常被省略。例如： His father died the year （that / when / in which）he was born.他父亲在他出生那年逝世了。 He is unlikely to find the place （that / where / in which）he lived forty years ago. 他不大可能找到他四十年前居住过的地方。 18.3 判断关系代词与关系副词 方法一：用关系代词，还是关系副词完全取决于从句中的谓语动词。及物动词后面无宾语，就必须要求用关系代词；而不及物动词则要求用关系副词。例如： This is the mountain village where I stayed last year. 这是我去年呆过的山村。 I'll never forget the days when I worked together with you.我永远不会忘记与你共事的日子。 判断改错： （错）This is the mountain village where I visited last year. （错）I will never forget the days when I spent in the countryside. （对）This is the mountain village （which）I visited last year. （对）I'll never forget the days （which）I spent in the countryside. 习惯上总把表地点或时间的名词与关系副词where, when联系在一起。此两题错在关系词的误用上。 方法二：准确判断先行词在定语从句中的成分（主、谓、宾、定、状），也能正确选择出关系代词/关

高中英语定语从句用法全面系统讲解

高中英语定语从句用法全面系统讲解（1） 一、概述 在复合句中，修饰某一名词或代词，用作定语的从句叫做定语从句(attributive clause)。被定语从句所修饰的词叫做先行词(antecedent)。定语从句必须放在先行词之后。引导定语从句的关联词有关系代词who、whom、whose、which、that和关系副词when、where、why 等。 Finally, the thief handed everything that he had stolen to the police. 最后，那个小偷向警察交出他偷的所有的东西。（引导词是关系代词that） His parents wouldn't let him marry anyone whose family was poor. 他父母不让他和家庭困难的人结婚。（引导词是关系代词whose） In the dark street, there wasn't a single person to whom she could turn for help. 在那个黑暗的街道上，没有她可以求助的人。（引导词是关系代词whom） In 1519 another traveller who went to America from Europe discovered the tomato. 1519年另一位从欧洲去美洲的旅行家发现了西红柿。（引导词是关系代词who） I still remember the day when I first came to Beijing. 我仍然记得第一次去北京的那一天。（引导词是关系副词when） This is the house where we lived last year. 这就是我们去年住的房子。（引导词是关系副词where） 二、关系代词和关系副词的功用能 关系代词和关系副词用来引导定语从句，在先行词和定语从句之间起纽带作用，使二者联系起来。关系代词和关系副词可作定语从句的一个成分。关系代词可作主语、宾语、定语；关系副词可作状语。 1、作主语 关系代词在定语从句中作主语时，从句的谓语动词的人称和数应与先行词一致。 All that is needed is a supply of oil. 所需要的是大量的油。（引导词that在句中作主语） A plane is a machine that can fly. 飞机是会飞的机器。（引导词that在句中作主语） The foreigner who visited our class yesterday is from Canada. 昨天到我班来访的外国人来自加拿大。（引导词who在句中作主语） They planted the trees which didn't need much water. 他们种植了需水不多的树木。（引导词which在句中作主语） 2、作宾语 在定语从句里作宾语的关系代词在口语中常被省去 The noodles (that) I cooked were delicious. 我煮的面条美味可口。（引导词that，可省略）

高一英语定语从句讲解精华版

定语从句 一、基本概念： 定语： 定语从句： Do you know the man who spoke at the meeting just now That is the house where he lived ten years ago. 引导词：关系词 关系代词有：that, who, whom, whose, which; 在从句中充当： 关系副词有：when, where, why. 在从句充当： 先行词： 定语从句中引关系词的作用： 二、关系词的用法： （一）关系代词的用法： 1． He is the man lives next door. The train has just left is for Shenzhen. 2． The man ________ we have just seen is a famous writer. Where is the book ___________I bought last week （二）关系副词的用法： 1． I still remember the time ________I first became a college student. Do you know the date __________Lincoln was born

(三) 使用关系副词应注意下列几点： 1．这三个关系副词在意义上都相当于一定的介词+which结构： when = on (in, at, during…) + which; where = in (at, on…) + which; why = for which. 如： I was in Beijing on the day when (=on which) he arrived. The office where (=in which) he works is on the third floor. This is the chief reason why (=for which) we did it. 2．当先行词是表时间的time, day等和表地点的place, house等时，一定要注意分析从句的结构，如果缺少主语或宾语时，关系词应该用which或that, 缺少时间状语或地点状语时，才能用when或where，试比较： I’ll never forget the day _________ my hometown was liberated. I’ll never forget the days____________we spent together last summer. His father works in a factory____________radio parts are made. His father works in a factory______________makes radio parts. 三．限制性定语从句与非限制性定语从句 1．限制性定语从句 This is the telegram which he refers to. Is there anything (that) I can do for you 2．非限制性定语从句 This note was left by Tom, who was here a moment ago. As a boy, he was always making things, most of which were electric.

初三英语定语从句用法详解

定语从句的用法 一、定语从句的概念 在复合句中,修饰某一名词或代词的从句叫定语从句。被修饰的名词或代词叫先行词,定语从句一般放在先行词的后面。(尤其是限制性定语从句) （定语在汉语中常用……的表示。它主要由形容词担任，此外，名词，代词，数词，分词，副词，不定式以及介词短语也可 以来担任，也可以有一个句子来担任。单词做定语是通常放在它所修饰的词之前，作前置定语。短语和从句做定语是则放在所 修饰的词之后，做后置定语。） 二、定语从句的关系词 引导定语从句的关系词有关系代词和关系副词,常见的关系代词包括that, which, who(宾格whom,所有格whose)等,关系副词包括where, when, why等。关系代词和关系副词放在先行词及定 语从句之间起连接作用,同时又作定语从句的重要成分。 三、定语从句的分类 根据定语从句与先行词的关系,定语从句可分为限制性定语从句及非限制性定语从句。 1. 限制性定语从句紧跟先行词,主句与从句不用逗号分开,从句不可省去 2.非限制性定语从句主句与从句之间有逗号分开,起补充说明作用,如省去,意思仍完整。 四、关系代词的用法 1. that 既可以用于指人,也可以用于指物。 Mary likes music that is quiet and gentle.玛丽喜欢轻柔的音乐。(that作主语) The coat (that) I put on the desk is blue.我放在桌子上的那件外套是蓝色的。(that作宾语) 2.which用于指物 The building which stands near the train station is a supermarket.位于火车站附近的那座大楼 是一家超市。(作主语) The film (which) we saw last night was wonderful. 我们昨天晚上看的那部电影很好看。(作宾语) 3.who, whom用于指人 The girl who often helps me with my English is from England.经常在英语方面帮助我的那个女 孩是英国人。(作主语) Who is the teacher (whom) Li Ming is talking to? 正在与李明谈话的老师是谁?(作宾语) 注意：whom 在口语和非正式语体中常用who代替，可省略。 4 whose用于指人，也可以用于指物（相当于of which 注明:whose=the+物/人+of which/whom ） Do you like the book whose color is yellow? Do you like the book the color of which is yellow? I once lived in the house whose roof has fallen in . I once lived in the house ,the roof of which has fallen in . 5.关系词的区别 （1）关系词只能用that的情况: a. 先行词被序数词或形容词最高级所修饰,或本身是序数词、基数词、形容词最高级时

高中英语定语从句详解

高中英语定语从句详解 定语从句用来充当句中定语的主谓结构；它主要用于修饰句子中的名词、代词。而定语从句的位置常常是紧跟在被修饰的名词、代词的后面。在被修饰的名词、代词与定语从句之间往往有一个关系词将其前后两部分联系成一个整体，或是构成一个名词短语；或是构成一个代词短语。但从结构上说，关系词与从句是一个整体。排除句子的其他各部分，这种带有定语从句的名词短语或是代词短语的构成可演示如下：1）three signs that indicate a person is suffering from a panic attack rather than a heart attack 三种意味着一个人是患有惊恐症而不是心脏病的迹象在这个带有定语从句的名词短语中： signs是：被修饰的名词； that是：关系词； that indicate a person is suffering from a panic attack rather than a heart attack是定语从句 2）those who drink a l ot 那些大量饮酒的人在这个带有定语从句的代词短语中： those是：被修饰的名词； who是：关系词; who drink a l ot是：定语从句通过上面的演示,我们可以归纳出定语从句在句子中的位置、结构如下：

被修饰的名词/ 代词+ 关系词+ 句子(其中，"被修饰的名词/代词"在语法叫作"先行词".) 要点提示： 1）"先行词"与"关系词"的内在联系"先行词"与"关系词"之间实质上是互等、互换的关系。也就是说，关系词的作用就是将先行词所表达意义"代到"从句中来起作用。例如： They often become easily frightened or feel uneasy in situations （先行词）where (关系词)peopl e normally woul d not be afraid . 他们常在人们一般不会感到害怕的情况下却很容易感到恐惧或是感到不自在。 （本句中的关系词where = 先行词（in）situations 。如果把这个复合句拆成两个分句，那就是： They often become easily frightened or feel uneasy in situations peopl e normally woul d not be afraid in situations 由此可以看出，"先行词"与"关系词"之间实质上是互等、互换的关系）。又例如： Rude peopl e are those （先行词）whose (关系词)behavior shows little respect for the rules（先行词）that(关系词) the majority follows . 不讲礼貌的人是指那些，他们的行为对大多数人所遵从的规

定语从句 定语从句 （一）、定义：在复合句中，修饰某一名词或代词的从句叫做定语从句。 定语定语用来限定、修饰名词或代词的，是对名词或代词起修饰、限定作用的词、短语（动词不定式短语、动名词短语和分词短语）或句子，汉语中常用‘……的’表示。主要由形容词担任，此外，名词，代词，数词，分词，副词，不定式以及介词短语也可以来担任，也可以由一个句子来担任。单词作定语时通常放在它所修饰的词之前，作前置定语。短语和从句作定语时则放在所修饰的词之后，作后置定语。 定语从句是指在一个句子中作定语的句子，定语从句要放在所修饰的词后。 如：1) The man who lives next to us is a policeman. 2) You must do everything that I do. 上面两句中的man和everything是定语从句所修饰的词，叫先行词，定语从句放在先行词的后面。 引导定语从句的词有关系代词that, which, who(宾格who, 所有格whose)和关系副词where, when、why 关系词常有三个作用：1、引导定语从句 2、代替先行词 3、在定语从句中担当一个成分 （二）、关系代词引导的定语从句 1.who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. 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) The man who/whom you met just now is my friend. 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. ( which 在句子中做主语) (2) This is the pen (which) he bought yesterday. ( which 在句子中做宾语) 4. that指人时，相当于who或者whom；指物时，相当于which。 在宾语从句中做主语或者宾语，做宾语时可省略。 (5) The people that/who come to visit the city are all here. (在句子中做主语) (6) Where is the man that/whom I saw this morning? (在句子中做宾语) 5. whose通常指人，也可指物，在定语从句中做定语 (1) He has a friend whose father is a doctor. (2) I lived in a house whose roof has fallen in. whose指物时，常用以下结构来代替 (3)The classroom whose door is broken will soon be repaired. =The classroom the door of which is broken will soon be repaired. (5)Do you like the book whose color is yellow? =Do you like the book the color of which is yellow? 注：that 用法 (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；在" such (the same) ... as ..." 句型中,关系代词要用as, 而不用which. We need such materials as (not which) can bear high temperature We depend on the land from which we get our food.
