定语从句基本概念
定语从句是由关系代词和关系副词引导的从句,其作用是作定语修饰主句的某个名词性成分,定语从句分为限制性和非限制性从句两种。下面是店铺收集整理的定语从句基本概念,希望对你有所帮助。

被修饰的词叫先行词。定语从句不同于单词作定语的情况,它需要放在被修饰的词(即先行词)之后。定语从句一般由关系代词来引导。关系代词必须放在定语从句之首。定语从句(Attributive Claus)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,在从句中所起作用如下:
Is he the man who/that wants to e you?
他就是想见你的人吗?(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) Who 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 who car had broken down. 那人车坏了,大家都跑过去帮忙。
Plea pass me the book who (of which) cover is green. 请递给我那本绿皮的书。
3)which, that
它们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 en before appears in the countryside. 农村出现了前所未有的繁荣。(which / that在句中作主语)

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)
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)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:炖排骨怎么做
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 refud 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
1997年是什么命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 / on 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。
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.
I'll never forget the days when I worked together with you.
判断改错(注:先显示题,再显示答案,横线;用不同的颜色表示 出。)
(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.合同补充协议模板
(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。
定语从句要点
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who)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:
王凤才
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 hou in which we lived last year.
这是我们去年居住的房子。
Plea 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 pasd 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:
