定语从句有哪几种【经典5篇】
定语从句有哪几种 篇一
定语从句是英语语法中的一种重要句型,用来修饰名词或代词,进一步说明其特征或性质。它可以为句子增加更多的信息,使得表达更加准确和丰富。在英语中,定语从句有几种不同的形式,包括限制性定语从句、非限制性定语从句和嵌套定语从句。
首先,限制性定语从句是最常见的一种形式。它用来限定或者具体说明名词或代词的范围。限制性定语从句通常不用逗号与主句分开,而是直接连接在名词或代词后面。例如,句子"The book that I borrowed from the library is very interesting." 中的定语从句"that I borrowed from the library" 限定了名词"book"。
其次,非限制性定语从句用来为名词或代词提供额外的信息,但不是必需的。这种形式的定语从句通常用逗号隔开,可以从句中去掉而不会影响整个句子的意思。例如,句子"My sister, who is a doctor, lives in London." 中的定语从句"who is a doctor" 提供了关于"my sister" 的额外信息。
最后,嵌套定语从句是指在一个定语从句中嵌入另一个定语从句。这种形式的定语从句可以用来修饰名词或代词,并且可以无限嵌套下去。例如,句子"The man who is talking to my sister is the teacher whose son is in my class." 中的定语从句"who is talking to my sister" 和"whose son is in my class" 都是嵌套定语从句。
总结起来,定语从句有限制性定语从句、非限制性定语从句和嵌套定语从句三种形式。限制性定语从句用于限定名词或代词的范围,非限制性定语从句用于提供额外信息,而嵌套定语从句则是在一个定语从句中嵌入另一个定语从句。熟练掌握这些不同的形式可以帮助我们更好地理解和运用定语从句,使我们的表达更加准确和流畅。

了解这些不同形式的定语从句对于我们正确理解和使用定语从句非常重要。限制性定语从句用于限定名词或代词的范围,非限制性定语从句用于提供额外信息,而嵌套定语从句则是在一个定语从句中嵌入另一个定语从句。通过掌握这些不同形式的定语从句,我们可以更好地运用它们来丰富我们的表达,使我们的句子更加准确和流畅。
定语从句有哪几种 篇三
定语从句是英语语法中的一种句子结构,用来修饰或限定名词或代词。根据定语从句的引导词和从句的特点,定语从句可以分为五种:关系代词引导的定语从句、关系副词引导的定语从句、介词+关系代词引导的定语从句、介词+关系副词引导的定语从句以及不定式引导的定语从句。
1. 关系代词引导的定语从句

我从图书馆借的那本书非常有趣。
- The girl who is wearing a red dress is my sister.
穿着红裙子的那个女孩是我妹妹。
2. 关系副词引导的定语从句

- This is the school where I study.
这是我就读的学校。
- Do you remember the day when we first met?
你还记得我们第一次见面的那天吗?
3. 介词+关系代词引导的定语从句

- This is the best book to read.
这是最好的一本书。
总的来说,定语从句根据引导词和从句的特点可以分为五种类型。掌握这些定语从句的形式和用法,可以帮助我们更准确地表达和理解句子的意思。
定语从句有哪几种 篇四
定语从句有哪几种 篇五
在生活、工作和学习中,大家都经常接触到句子吧,不同的句子类型在文章中具有不同的作用。你知道什么样的句子才能称之为经典吗?下面是小编收集整理的定语从句有哪几种,欢迎阅读,希望大家能够喜欢。
一、 限制性与非限制性定语从句
(一) 限制性定语从句与非限制性定语从句的区别
限制性定语从句对先行词起修饰限制作用;而非限制性定语从句是对先行词起补充说明作用。非限制性定语从句中,先行词与定语从句往往有逗号割开。非限制性定语从句相当于并列句、状语从句等。如:
I want this man, who (=for he) can speak English.
He gave up the plan, which (=though it) was a very good one.
I met John, who (=and he) told me the news.
I will take this one, which (=for it) seems to be the best one.
He has two sons, who work in the same company. (He has only two sons.)
He has two sons who work in the same company. (Perhaps he has more than two sons.)
(二) 非限制性定语从句中关系代词和关系副词的用法
1、 关系代词和关系副词在任何情况下都不能省略;
2、 Who(主语),whom(宾语),which(主语、宾语)不能用that代替,也不能互相替换;
3、 介词+which/whom+从句结构中,介词不能移到从句的后面;
4、 when, where可用于非限制性定语从句。
二、 关系代词的用法
(一) 关系代词的作用和分类
1、关系代词的作用有三个:
(1) 连接作用:关系代词引导从句,把它和主句连接起来;
(2) 替代作用:关系代词在从句中替代它前面的先行词;
(3) 成分作用:关系代词在从句中总是充当句子成分。
2、关系代词的用法分类
关系代词的用法与分类有三点依据:
(1) 根据所引导的从句的限制性和非限制性;
(2) 根据所替代的先行词是指人还是指物;
(3) 根据它在从句中所充当的成分----主语、宾语、表语或者定语。
(二) 关系代词that和which的用法
1、 限制性定语从句中,必须用关系代词that的情况:
(1) 当先行词是不定代词all, much, little, something, everything, anything,
nothing, the one时。如:
Do you have anything that you want to say for yourself?
You should hand in all that you have.
(2) 当先行词前面被the only, the very, any, few, little, no, all等词修饰时。
如:
This is the very person that I’m waiting for.
The only thing that we can do is to give you some money.
(3) 当先行词是形容词最高级或者先行词的前面有形容词最高级修饰时。如: This is the best that has been used against pollution.
This is the most interesting film that I’ve ever seen.
(4) 当先行词是序数词或它前面有序数词修饰时。如:
This train is the last that will go to Suzhou.
What is the first American film that you have seen?
(5) 当先行词既有人又有物时。如:
Do you know the things and persons that they are talking about?
(6) 当主句的主语是疑问词who或which时。如:
Which is the bike that you lost?
Who is the boy that won the gold medal?
(7) 有两个定语从句时,其中一个关系代词也在从句中作表语时。如:
They secretly built up a small factory, which produced things that could cause pollution.
(8) 当先行词在主句中作表语,而关系代词也在从句中作表语时。如:
Shanghai is no longer the city that is used to be.
2、 定语从句中,必须用which的情况:
(1) 在非限制性定语从句中,只用which不用that。如:
Helen was much kinder to her youngest son than to the others, which, of course, made the others envy him.
(2) 当动词短语中的介词提前时,只用which不用that。如:
This is a house in which Lu Xun once lived.
注意:在一些固定搭配的动词短语中,由于动词和介词不可分割,因此把介词置于关系代词之前。如:
This is the pen (which/that) I’ m looking for.
(三) 关系代词who, whom和whose的用法
先行词指人:在定语从句中作主语时,用who,不克省略;在定语从句中作宾语时,用whom/that,可以省略;在定语从句中坐定语时,用whose,不可省略。如:
She is the girl who lives next door.作主语
That’s the girl (whom/that) I teach.作宾语
That’s the scientist whose achievements are well known.作定语
This is the house whose window broke last night.
= This is the house, the window of which broke last night.
= This is the house, of which the widow broke last night.
(四)“介词+关系代词”引导的定语从句
“介词+关系代词”引导定语从句时,关系代词只能用which或whom,即:介词+whom/which。
1. 当介词放在关系代词的前面时,关系代词只能用which或whom,关系代词不能省略。如:
(1) Is this the house in which Shakespeare was born?
(2) He paid the boy 10 Yuan for washing ten windows, most of which hadn’t
been cleaned for at least a year.
(3) In the dark street, there wasn’t a single person to whom she could turn
for help.
(4) Recently I bought an ancient vase, the price of which was very
reasonable.
(5) The gentleman about whom you told me yesterday proved to be a thief.
2.在限制性定语从句中,当介词位于定语从句的末尾时,可用that/which ,that/whom/who作介词的宾语,而且作介词宾语的关系代词可以省略。如:
3.”复合介词短语+关系代词which”引导的定语从句,这种结构引导的定语从句常与先行词用逗号分开,定语从句常用倒装语序。如:
He lived in a big house, in front of which stood a big tall tree.
4.介词+which/whom+不定式结构
The poor man has no house in which to live.
= The poor man has no house to live in.
= The poor man has no house in which he can live.
(五)关系代词as引导的定语从句
关系代词as既可以引导限制性定语从句,也可以引导非限制性定语从句,as在从句中作主语、宾语或表语。
引导限制性定语从句常用于下列形式:
名词+as像一样的,像之类
名词+as 和同样的
其中关系代词as在从句中担当主语、宾语或表语。如:
We have found such materials as are used in their factory.
He is not the same man as he was.
2.such as
Such为代词,意为“这样的人或物”,as在从句中担当成分,修饰先行词such.如: This book is not such as I expect.
(六)关系代词as, which的区别
1.as引导的非限制性定语从句,既可在主句前,又可在主句后,有时还克插入主句中,而which引导的非限制性定语从句只能置于主句之后。相同的是两者都可以替代主句的整个内容,而不是主句中的某一个词。如:
The weather turned out to be very good, which was more than we could expect. By serving others, a person focuses on someone other than himself or herself, which can be very eye-opening and rewarding.
2. 当非限制性定语从句放在主句前面时,只能用as.如:
As is known to everybody, the moon travels round the earth once every month. = The moon travels round the earth once every month, as/which is known to everybody. = It is known to everybody that the moon travels round the earth once everybody. = What is known to everybody is that the moon travels round the earth once every month.
后面两句属于名词性从句范畴。
另外,as多用于下列习惯用语中:as anybody can see 正如人人都能看到的那样;as is well-known=as is known to all众所周知;as we had expected正如我们所预料的那样;as often happens 正如经常发生的那样;as has been said before 如上所述;as is mentioned above正如上面提到的。
3.当定语从句放在主句后面是,也并不是as就能永远等于which.
(1)当限定性定于从句是否定句或表示否定时只能用which.如:
He came here very late, which was unexpected.
Mr. Smith usually praises his students Rose in public, which she doesn’t like at all.
(2)当as在从句中作主语时,后面常接动词的被动语态。如:be known, be said, be reported, be announced等。如果从句中行为动词是主动语态,一般用which作主语。如: She has been absent again, as is expected. 她又缺席了,这在预料之中。 Tom has made rapid progress, which makes me very happy. Tom取得了很大的进步,这使我很高兴。
(3)用在as(it) seems likely, as(it) often happiness, as(it) was printed out, as(it) was said earlier, as I remember (it), as I understand(it), as (it) appears等结构中。如:
Jack has won the first prize, as it often happens.
Jack和往常一样,获得了一等奖。
She has read widely in Romantic literature, as it appears from her essay. 她广泛涉猎了浪漫主意文学,这从她的文章中可以看出来。
(4)as仍然保持作连词时常有的某种含义。如:
David is tall, as are my brothers.
David很高,我的兄弟也一样。
He opposed the idea, as could be expected.
不出所料,他反对这个意见。
(5)当非限定性定语从句的谓语是一个复合结构时,只能用which引导定语从句。如:Betty always tells a lie, which her parents find strange.
(6)当非限定性定语从句为否定句时,常用which.如:
Mr. Smith usually praises his student Rose in public, which she doesn’t like at all.
三、关系副词的用法
(一)当先行词在定语从句中作状语时,要用关系副词。其中when=表时间的介词(如:ai, in, during等)+which; where=表地点的介词(如:in, at, on, under等)+which; why=表原因的介词(如:for)+which; how=表方式的介词(如:in)+which。如:
I still remember the day when I first came to Beijing.(when=on which)
Can you tell me the office where he works? (where=in which)
Do you know the reason why he is absent?(why=for which)
(二)介词+关系代词(which)=where/when.有时候为表达清楚,还可以在关系副词where/when前加介词from, to等。如:China is the birth place of kite, from where kite flying spread to Japan, Korea, Thailand and India.
(三)对关系副词where的考察
对于where的考察趋于复杂,从先行词为明显的“地点”转化为“地点的.模糊化”。事实上,对于where这个词,不能只理解为表示地点。先行词表示某人或物的situation,或者某事所发展的stage,或表达某事的某个方面时,都可以用where,这个关系副词,如:
The accident had reached to a point where both their parents are to be called in. 事情发展到如此程度,不得不请双方家长来一趟了。
这种用法不仅仅限于定语从句,特殊疑问句中、名词性从句中也有如此用法。
四、关系副词和关系代词的比较
引导定语从句的关系代词及关系副词除了起连接先行词和从句的作用外,他们还有一个最重要的作用,那就是他们分别在定语从句中担当成分。具体地说,关系代词在定语从句中作表语、主语、宾语,而关系副词在定语从句中做状语。因此,在选择关系时,最重要的是分析一下定语从句中的成分,若从句中却主语、宾语或表语,那么必须用关系代词,若主句中不缺主语、宾语或表语则用关系副词。
试比较下面的句子:
(1)、Do you still remember the days that/which we spent in Beijing?(代)
(2)、Do you still remember the days when we spent the summer holidays in Beijing?(副)
在句中,定语从句中缺宾语,第二局中,定语从句不缺宾语也不缺主语,因此用关系副词when来引导。
五、定语从句用法其他要点
(一)、关系代词在定语从句中作主语时,不可省略。
(二)、定语从句中的谓语动词与先行词保持一致;当引导定语从句的关系代词在从句中作主语时,那么定语从句中的谓语动词在人称、数的方面,应该与先行词保持一致。
1.one of + 复数名词+关系代词+复数动词。如:
The Great Wall is one of the world-famous buildings that draw lots of visitors.长城是吸引大批游客的世界著名的建筑之一。
Titanic is one of the wonderful movies that have been produced in Hollywood. 《泰坦尼克号》是好莱坞生产的最精彩的电影之一。
2.the only one of+复数名词+关系代词+单数动词。如:
The Great Wall is the only one of the buildings on the earth that is seen from the moon.长城是地球是唯一一个能从月球上看到的建筑物。
Titanic is the only one of these wonderful movies that has been produced in Hollywood. 在这些精彩的电影中,《泰坦尼克号》是唯一由好莱坞制作的电影。
注意:not the only one of=one of如:
Tom isn’t the only one of the boys who have passed the exam.
=Tom is one of the boys who have passed the exam.
Tom 并非是唯一一个通过考试的男孩=Tom只是通过考试的男孩中的一个。
3.当关系代词as与which引导非限制性定语从句,修饰主句内容时,若as与which作主语,则从局的谓语动词用单数形式。如:
Great changes have taken place in China, as is known to all.
He has passed the college entrance examination, which makes his parents quite happy.
4.其他情况
I, who am your teacher, will try my best to help you.
To own a computer in families, which we thought was impossible twenty years ago, now becomes true.
(三)、注意way和time后接定语从句的情况
1.当先行词是way意味“方式、方法”时,引导定语从句的关系代词有下列三种形式 不填
他向我们解释的那种方法很简单。
The which he explained the sentence to us was not difficult to understand. 不填
他向我解释句子的那种方法不难理解。
2.先行词是time,若time作“次数”讲时,应用关系代词that引导定语从句,that可省略;若time作“一段时间”讲时,应用关系副词when或介词at/during+which引导定语从句。如:This is the second time (that) the President has visited the country. I could hardly remember how many times (that) I have failed.
拓展:定语从句that
that常用作关系代词,可指代某人,也可指代某物,指物时有的时候可用which替换that,指人时可用who替换。但在下列情况下,一般用that。
一、that指代某物事时

(6)This is the very factory that they visited last summer holiday.
这恰好是他们去年参观的那个工厂。
(7)This is the only painting in this style that we have.
这种风格的画我们仅有一幅。
5. 先行词是并列结构,既有人又有物时。如:

6. 先行词前有the same 修饰,表示和先行词是同一物时。如:
(9)This is the same purse that I lost yesterday.
这就是我昨天丢的那个钱夹。
注:如果表示的是与先行词同一类或相似的某物,则用the same…as….如:

7. 先行词为数词时。
(1
1)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。

二、that 指代某人时。
1. 泛指某人时。如:
(16)He is a man that is never at a loss.
他是一个从未一筹莫展的人。
2. 主句是以作主语的who开头的特殊问句,为了避免重复时。如:
