初中阶段,定语从句可以说是一个难点。下面是小编辛苦为朋友们带来的8篇《什么叫做定语从句》,如果能帮助到亲,我们的一切努力都是值得的。

什么叫做定语从句 篇一

1. think it + adj + that

在讲今天的语法之前,我们回顾一下平时同学们在写作以及阅读中可能比较疑惑的例句:

I think it important that you tell your mother the truth.

疑惑之处在于,it后面为什么没有is?

例句采用了这样的句型:“think it + adj”。此处,it为形式宾语,that引导的宾语从句才是真实宾语,而important是宾语补足语。所以,it是形式宾语而不是主语,不需要加be动词。

一般情况下,各位更熟悉的句型是:“I think (that) it is important that.。. ”;这两者都是正确的,注意区分和辨别。

感兴趣的同学还可以去这个网站看看:English Language & Usage。它给出了以下几个类似的例句:

e.g. We do not think it necessary to go.

e.g. Some people do not think it important to be thrifty.

2. 定语从句中的that

定语从句中比较容易处理方面是,定语从句中“that”多可省略,表现为关系代词作宾语的情况:

e.g. He must be the man (that) you have been looking for.

此处,man作looking for的宾语。

至于不可省略的that,这里小编只举两例,算是比较常用的规则哦:

(1)紧接着上面阐述,除了关系代词作宾语的情况外,其余时候多不能省略that。比如小编给各位找来一个作主语的例子,各位可以举一反三:

e.g. All that glitters is not gold.(发光的未必都是金子。)

此处,that指代主语,不可以省略。

(2)我们都知道that引导定语从句,可指人也可指物,算是兼有“who”和“which”的作用;但当定语从句修饰的先行词既有人又有物时,那么就只能用that且不可省略了。

e.g. I still remember the things and persons that I met when I traveled to Tibet.

接下来再给各位同学出一道题检验一下今天学习的知识点到底掌握了没有,题目如下:

This is the fastest train that there is to Beijing.

上句话中的that是否可以省略?

A. yes

B. no

答案:A、可以省略。

(1)首先我们来判断一下此处that引导的从句在句子中是什么成分:

This is the fastest train that there is to Beijing 。

由于there be句型的特殊性,并不是跟在be动词后面的就一定是宾语,there be句型本身就是一个倒装。这种句型之所以要用there作引导词,而把主语置于动词之后,是为了使主语成为信息中心,以达到引出新话题的目的。上述例句中的train是定语从句中的主语成分。

(2)认真学习的同学肯定还记得上期小编总结了一句“定语从句中that多可省略,表现为关系代词作宾语的情况”,因此各位就倾向于记住宾语之外的成分都不可以省略that,但there be结构却是特例。具体语法点为:在there be结构中出现定语从句,或在定语从句中出现there be时,用作主语的关系代词也可省略。

(3)因此,上述例句中的train虽作从句的主语成分,但由于there be结构的特殊性,that仍旧可以省略。此处特例建立在固定结构的用法基础上,也算是有规律可循的特例了。

介词+关系词 篇二

1)介词后面的关系词不能省略。

2)that前不能有介词。

3) 某些在从句中充当时间,地点或原因状语的"介词+关系词"结构可以同关系副词when 和where 互换。

This is the house in which I lived two years ago.

This is the house where I lived two years ago.

Do you remember the day on which you joined our club?

Do you remember the day when you joined our club?

什么叫做定语从句 篇三

一、指人的意思

that用于指人,在定语从句中可用作主语、宾语或表语。如:

A driver that has knocked someone down must stop. 撞人的司机必须停车。(关系代词that指driver,在从句中作主语)

He is the man that you have been looking for. 他就是你要找的那个人。(关系代词that指man,在从句中作宾语)

He is not that man that he was. 他已不是过去的他了。(关系代词that指man,在从句中作表语)

二、指物的意思

that用于指物,在定语从句中可用作主语、宾语或表语。如:

This is the plane that will fly to Tokyo in the afternoon. 这是下午要飞往东京的那架飞机。(关系代词that指plane,在定语从句中作主语)

She was annoyed by something that I had said. 她为我说的某句话而不高兴。(关系代词that指something,在定语从句中作宾语)

Shengzhen is not the city that it used to be. 深圳现在已不是原来的那个城市了。(关系代词that指city,在定语从句中作表语)

三、不用that的情况

(1) 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.

(2) 介词后不能用。

We depend on the land from which we get our food.

We depend on the land that/which we get our food from.

四、 只能用that作为定语从句的关系代词的情况

(1) 在there be 句型中,只用that,不用which。

(2) 在不定代词,如:anything, nothing, the one, all等作先行词时,只用that,不用which。

(3) 先行词有the only, the very,the same,the last,just修饰时,只用that。

(4) 先行词为序数词、数词、形容词最高级时,只用that,不能用which。。

(5) 先行词既有人,又有物时。

(6) 先行词指物,在主句中作表语时。

(7) 为了避免重复。

(8) 先行词是the way或the reason时,that可作关系副词,也可省略

(9) 主句的主语是疑问词who /which时

关系副词引导的定语从句 篇四

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)when, where, why

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

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。

什么叫做定语从句 篇五

(11)Look at the books on the bookshelf. You can see the two that you bought me for my birthday.

瞧书架上那些书。你可以看到我过生日时你买的那两本。

(12)They built a factory which produced things that had never been seen.

他们建了一工厂,生产以前从未见过的东西。

9、 以which作主语开头的特殊问句,为了避免重复,定语从句用that。如。

(注:先行词是time,前面有序数词或last修饰时,常用that引导定语从句或者省略。)

当先行词为表示方式的词the way时,可用that引导定语从句, that常可以省略。

(24)I don't the way you speak to her.

我不喜欢你和她说话那种方式。

定语从句归纳及用法 篇六

定语从句在初中英语中的重要性主要体现在完形、阅读和写作中,因此,能否较好的掌握定语从句直接关系到你英语成绩的拔高。其实,定语从句并不难。

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,引导定语从句的词叫关系词,定语从句一般放在先行词的后面。

二。 引导定语从句的关系词

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。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。非限制性定语从句与主句之间有逗号分开,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。在从句中作主语、宾语或表语。作主语时不可省略,作宾语可省略。例如:

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,在句中作主语、宾语或表语。作主语不可省略,作宾语可省略。例如:

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,who 用作主语,whom用作宾语。在口语中,有时可用who代替whom。who和whom作宾语时也可省略。例如:

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:

(1)当定语从句中含有介词,介词放在句末时,who,whom,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:

This is the house in which we lived last year.

这是我们去年居住的房子。

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等不定代词指物时,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:

Whats 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,which,而不用that.例如:

这是他居住的房间。

c. 引导非限制性定语从句,先行词指事物时,用which, 而不用that,例如:

Tom came back, which made us happy.

五。 关系副词的用法

1、 when指时间,其先行词表示时间,when在定语从句中作时间状语。例如:

2、 where指地点,其先行词表示地点,where在定语从句中作地点状语。例如:

This is place where he works.

这是他工作的地点。

3、 why 指原因,其先行词是原因,why在定语从句中做原因状语。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。

关系代词that 的用法 篇七

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.

We depend on the land that/which we get our food from.

2) 只能用that作为定语从句的关系代词的情况

a) 在there be 句型中,只用that,不用which。

b) 在不定代词,如:anything, nothing, the one, all, much, few, any, little等作先行词时,只用that,不用which。

c) 先行词有the only, the very修饰时,只用that。

e) 先行词既有人,又有物时。

举例:

All that is needed is a supply of oil.

所需的只是供油问题。

Finally, the thief handed everything that he had stolen to the police.

那贼最终把偷的全部东西交给了警察。

定语从句归纳及用法 篇八

I 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,英语定语从句知识和用法概述。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)

II. 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"介词+ 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。

III.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/关系副词。

例1. Is this museum ___ you visited a few days age?

A. where B. that C. on which D. the one

例2. Is this the museum ____ the exhibition was held.

A. where B. that C. on which D. the one

答案:例1 D,例2 A

例1变为肯定句: This museum is ___ you visited a few days ago.

例2变为肯定句: This is the museum ___ the exhibition was held.

在句1中,所缺部分为宾语,而where, that, on which都不能起到宾语的作用,只有the one既做了主句的表语,又可做从句的宾语,可以省略关系代词,所以应选D,英语语法《英语定语从句知识和用法概述》。

而句2中, 主、谓、宾俱全,从句部分为句子的状语表地点,既可用副词where,又因 in the museum词组,可用介词in + which 引导地点状语。而此题中,介词on 用的不对,所以选A。

关系词的选择依据在从句中所做的成分,先行词在从句中做主、定、宾语时,选择关系代词(who, whom, that, which, whose); 先行词在从句中做状语时,应选择关系副词 ( where 地点状语,when 时间状语,why 原因状语) 。

IV. 限制性和非限制性定语从句

1) 定语从句有限制性和非限制性两种。限制性定语从句是先行词不可缺少的部分,去掉它主句意思往往不明确;非限制性定语从句是先行词的附加说明,去掉了也不会影响主句的意思,它与主句之间通常用逗号分开。例如:

This is the house which we bought last month. 这是我们上个月买的那幢房子。(限制性)

The house, which we bought last month, is very nice.这幢房子很漂亮,是我们上个月买的。(非限制性)

2) 当先行词是专有名词或物主代词和指示代词所修饰时,其后的定语从句通常是非限制性的。例如:

Charles Smith, who was my former teacher, retired last year. 查理?史密斯去年退休了,他曾经是我的老师。

My house, which I bought last year, has got a lovely garden. 我去年买的'的那幢房子带着个漂亮的花园。

This novel, which I have read three times, is very touching. 这本小说很动人,我已经读了三遍。

3) 非限制性定语从句还能将整个主句作为先行词, 对其进行修饰, 这时从句谓语动词要用第三人称单数。例如:

He seems not to have grasped what I meant, which greatly upsets me. 他似乎没抓住我的意思,这使我心烦。

Liquid water changes to vapor, which is called evaporation. 液态水变为蒸汽,这就叫做蒸发。

说明:关系代词that和关系副词why不能引导非限制性定语从句。

V. 介词+关系词

1)介词后面的关系词不能省略。

2)that前不能有介词。

3)某些在从句中充当时间,地点或原因状语的"介词+关系词"结构可以同关系副词when 和where 互换。例如:

This is the house in which I lived two years ago. 这是我两年前住过的房子。

This is the house where I lived two years ago.

Do you remember the day on which you joined our club? 还记得你加入我们俱乐部的那一天吗?

Do you remember the day when you joined our club?

VI. as, which 非限定性定语从句

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。例如:

As we know, smoking is harmful to one's health. 如我们所知,吸烟有害健康。

The sun heats the earth, which is very important to us. 太阳使地球暖起来,这对我们人类很重要。

典型例题

1)Alice received an invitation from her boss, ___came as a surprise.

A. it B. that C. which D. he

答案C. 此为非限定性从句,不能用 that修饰,而用which.,it 和he 都使后

句成为句子,两个独立的句子不能单以逗号连接。况且选he句意不通。

2)The weather turned out to be very good, ___ was more than we could expect.

A. what B. which C. that D. it

答案B。which可代替句子,用于非限定性定语从句,而what不可。That 不能用于非限定性定语从句,it不为连词,使由逗号连接的两个句子并在一起在英语语法上行不通。

3)It rained hard yesterday, ____ prevented me from going to the park.。

A. that B. which C. as D. it

答案B. as 和which在引导非限制性定语从句时,这两个关系代词都指主句所表达的整个意思,且在定语从句中都可以作主语和宾语。但不同之处主要有两点:

(1)as 引导的定语从句可置于句首,而which不可。

(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.。在本题中,prevent由于是行为动词,所以正确选项应为B。

as 的用法

例1. the same…as;such…as 中的as 是一种固定结构, 和……一样……。例如:

I have got into the same trouble as he (has)。 我碰到了跟他一样的麻烦。

例2. as可引导非限制性从句,常带有'正如'。例如:

As we know, smoking is harmful to one's health. 如我们所知,吸烟有害健康。

As is known, smoking is harmful to one's health.

As是关系代词。例1中的as作know的宾语;例2中,它充当从句的主语,谓语动词know要用被动式。

VII. 先行词和关系词二合一

1) Whoever spits in public will be punished here. (Whoever 可以用 anyone who 代替)
