限制性定语从句与非限制性定语从句用法区别:



一、 句法功能、表现形式不同



定语从句分为限制性和非限制性两种。限制性定语从句不可缺少先行词,去掉它主句意思往往就不明确了,它与主句之间通常不用逗号分开;非限制性定语从句是对先行词的附加说明,去掉它也不会影响主句的意思。如:



Do you know the professor who is speaking at the meeting? (限制性定语从句)


English is an important subject, which every student should study well. (非限制性定语从句)



二、 先行词不尽相同


限制性定语从句的先行词往往是某一个词,但非限制性定语从句的先行词可以是一个词,也可以是句子的一部分,甚至是整个主句,此时非限制性定语从句一般由which或as引导,as引导非限制性定语从句常用在as is said / known / expected / mentioned / reported / announced等结构中。如:



He has passed the college entrance examination, which makes his parents quite happy.



As is known to everybody, the moon travels round the earth once every month.



三、 关系词的使用情况有所不同



1. that 不可引导非限制性定语从句。如:



Her father gave her a computer for her birthday,which pleased her a lot.



2. why 不用在非限制性定语从句中,需用for which代替。如:



I told them the reason, for which I didn't attend the party last week.



3. 关系代词替代情况不同


关系代词 whom 在限制性定语从句中作宾语时可用 who 代替 whom, 但 whom 在非限制性定语从句中作宾语时不可用 who代替。如:



This is the girl whom (who) I have been in love with for six years.



The young man had a new girl friend, whom he wanted to show all his love for.



4. 关系代词省略情况不同



关系代词在限制性定语从句中作宾语时可以省略;非限制性定语从句的所有关系代词均不可省略。如:



She is the new student (whom / who / that) I want to introduce to you.



All the books there, which have beautiful pictures in them, were written by him.



四、 下列情形用非限制性定语从句



1. 当“不定数量词 (如some, several) / 数词 + of which / whom”表示“整体 (which / whom)中的一部分”的概念时。如:


We saw many animals in the zoo, some of which are tigers.


There are fifteen new players in our team, two of whom come from Canada.



2. 当先行词为专有名词或被物主代词和指示代词修饰时,其后的定语从句通常是非限制性的。如:



My house, which I bought last year, has got a lovely garden.


Qingdao, where I have been three times, is an attractive city to foreigners.

扩展资料:


非限定性定语从句起补充说明作用,在句子中不充当成分,缺少也不会影响全句的理解,它与主句往往用逗号隔开。

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,将非限定性定语从句放在句子中间,其前后都需要用逗号隔开。

定语从句就其与先行词的关系而言,可分为限定性和非限定性两种,这两种的主要区别如下:

限定性定语从句,起限定作作用,若省去,原句意义不完整;其紧跟先行词后,无逗号隔开;起修饰先行词的作用,常译为先行词的定语,关系词有时可由that代替,有时也可省略。
非限定性定语从句,起补充说明作用,若省去,原句的意义不受影响;有逗号与主句分开,既可以修饰先行词也可以修饰整个主句;常译为另一分句,关系词不可用that,也不可省略。

扩展资料

限定性

限定性定语从句

意义:

限定性定语从句对被修饰的先行词有限定制约作用,使该词的含义更具体,更明确。限制性定语从句不能被省略,否则句意就不完整,例如I met some one who said he knows you.

在引导限定性定语从句时,that有时相当于in which,at which,for which或on which

(1)Attitudes towards daydreaming are changing in much the same way that(in which) attitudes towards night dreaming have changed. 人们对白日做梦的态度正在改变,这与人们对夜间做梦的看法的变化有非常相似之处。

(2)I like the music for the very reason that(for which) he dislike it. 我出于某种原因喜欢这种音乐,而他恰恰与我相反。

(3)We arrived the day that(on which) they left. 刚好我们到的那天他们走了。

在限定性定语从句中,当关系代词在从句中担任动词宾语时,关系代词可省略。

(1)The book (that/ which) I am reading is very interesting. 我在读的书很有趣。

(2)Is there anything (that) you wanted? 想要什么东西吗?

非限定性

非限定性定语从句

意义:

非限定性定语从句起补充说明作用,缺少也不会影响全句的理解。在非限制性定语从句的前面往往有逗号隔开,如

(1)The house,which I bought has a lovely garden. 我买的房子带着个漂亮的花园。

(2)This novel, which I have read three times, is very touching. 这本我已经读过三遍的小说很感人。

1.非限定性定语从句可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:

(1)He seems not to have grasped what I meant, which greatly upsets me.他似乎没理解我的意思,这使我心烦。

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

2. 在非限定定语从句中,有时as也可用作关系代词,若as在从句中作主语,其引导的句子可以放在句首,也可以放在句中。例如:

(1)The boy has as much progress as we had expected. 正像我们所预料的那样,这个男孩取得了大的进步。

(2) As everyone knows ,China is a beautiful country with a long history . 每个人都知道,中国是一个有着悠久历史的美丽国家。

3. 在非限定性定语从句中,不能用从句做主语

(1)[错]The boys ,who are playing football ,are from Class One. 在踢足球的男孩们是一班的。

(2)[错]I helped an old man ,who lost his way ,yesterday . 昨天,我帮助了一个迷路的老人。

1、定语从句就其与先行词的关系而言,可分为限定性和非限定性两种,这两种的主要区别如下:
限定性定语从句,起限定作作用,若省去,原句意义不完整;其紧跟先行词后,无逗号隔开;起修饰先行词的作用,常译为先行词的定语,关系词有时可由that代替,有时也可省略。
非限定性定语从句,起补充说明作用,若省去,原句的意义不受影响;有逗号与主句分开,既可以修饰先行词也可以修饰整个主句;常译为另一分句,关系词不可用that,也不可省略。
2、举例说明
限定性从句起限定作用和非限定性从句起补充说明作用:
July is the month when we have a lot of rain.七月是多雨的月份。(限定性,省去意义不完整,译成定语)
The meeting will be put off till next month when we will have made all the preparations.会议将推迟到下个月,那时我们将做好一切准备。(非限定性,省去后主句意义受影响小,译成另一并列分句)
限定性人名关系词有时可用that代替和非限定性从句关系词不可用that
I want to bugy the house which (=that) has a garden.我想买那座带花园的房子。
I want to buy the house, which (不能用that) has a garden.我想买那房子,它有一个花园。
非限定性定语从句还可以将整个主句作为先行词,对其进行修饰。如:
He missed the train, which annoyed him very much.他错过了火车,这使得他很恼火。
同一个定语从句,是限定性的还是非限定性的,意义可能差别很大。如:
He has a daughter who works in a hospital.他有一个在医院工作的女儿。(限定性的,可能还有别的女儿,但不在医院工作)
He has a daughter, who works in a hospital.他有一个女儿,在医院工作。(只有这么一个女儿)
I will wear no clothes which will distinguish me from the others.我将不穿会使我与众不同的衣服。(限定性)
I will wear no clothes, which will distinguish me from the others.我将不穿衣服,这样会使我与众不同。(非限定性)
