完整全面定语从句知识点

The Attributive Clause
定语从句：在英语复合句中，由关联 词引导，修饰句中的名词、代词,有时也修饰主句的一部份或整个句子的从句称为定语从句.
它分为：限制性定语从句和非限制性定语从句。

被定语从句所修饰的那个词称为先行词。

关系代词:which, that ， who, whom, whose ，as(在句中充当成分，可作主语,宾语，表语，定语） 引导词
关系副词：when ， where, why ，在句中只作状语。

e 。

g 。

引导词(从句中做主语）
关系词的作用：1.引导定语从句;2。

代替先行词；3。

在从句中担当一个成分
e 。

g. This is the best film that I have seen.
Ⅰ 关系代词
（1)who, whom 引导的定语从句
b 。

（2）that 引导的定语从句

(4）whose 引导的定语从句
whose 是关系代词who 与which 的所有格形式，用作名词的限定语, whose 指人或物,在从句中作定语。

Have you seen a dictionary whose cover is blue ？
(the cover of which is blue ）？
▲whose 经常后接名词，这结构可以用the+名词＋of+whom/which 来替换，意义不变。

也就是说，表示所属关系， whose + n 。

= of which/ whom + the + n.
= the + n 。

+ of which/ whom
e.g 。

He is an whose daughter studies abroad 。

excellent teacher ， the daughter of whom studies abroad 。

2. They live in a house，whose door faces south.
=_They live in a house,________________________________________________
=_They live in a house，________________________________________________
（5）非限制性定语从句中，要表示先行词的一部分时，可用“数词/代词+ of + 关系代词”的结构，如：
e。

g. There are 60 students in our class，two thirds of whom have been to Beijing
【练习】1。

【总结】名词/代词/数词+ of +which/whom 表示：1）所有关系2)整体与部分关系
【注意】关系代词引导定语从句时，要注意几点：
1。

whom，which作介词宾语时,介词一般可以放在它们的前面,也可以放在从句原来的位置上，但是含有介词的动词固定词组中，介词应该放在原来的位置上。

There is a room in which you can study.
which you can study in。

Rose is the student after whom you should look. ╳
/of whom you should take care. ╳
Rose is the student whom you should look after/take care of. √
2. ☆只用that不用which的情况:
1)。

当先行词是不定代词时，如:all, everything, anything，nothing, much，few，little, none，the one等。

All that can be done has been done。

2）。

先行词前有few，little，no，all，every等词修饰时。

There is no difficulty that we can’t overcome。

3）先行词被the only, the very, the right，just the，one of 等修饰时.
This is the very book that belongs to him.
This is one of the toys that interest the boy。

4）.先行词被序数词first, last，等或形容词的最高级修饰时.
This is the first/best letter that I’ve written in English.
5).当先行词既有人又有物时。

They talked about the teachers and the schools (that) they had visited。

6).当关系词在从句中作表语时。

China isn't the country that she used to be 50 years ago。

7）当主句是以who，which，或what开头的特殊疑问句时。

Who is the man that is waiting at the bus stop？
What did you hear that made you so angry?Which is the book that you need?
8)there be 句型中,先行词指物时。

There is a seat in the corner that is still free。

☆只用which不用that的情况
1）引导非限制性定语从句。

His money was stolen by a thief，which made him very sad.
2）。

当关系代词前有介词。

This is the factory in which my mother works。

3）。

当先行词本身是that时.
What’s that which flashed in the sky just now。

4）。

当关系词后有插入语时
This is the dictionary which，as I have told you，is helpful for you。

5）。

为避免重复
The book that I gave you just now is about computer science which is very important.
☆只用who不用that 的情况
1）当先行词是one ，ones，anyone,those或people时

God help those who help themselves。

2）当先行词是I, he, they，you等时(常用于谚语中)
❖He who plays with fire gets burned。

❖I，who am your friend，will give you a hand when you are in trouble。

3）在there be结构中，先行词指人时。

4）在非限制性定语从句中

注意：关系代词who，which, that，在从句中作主语时,从句的谓语动词的人称和数必须必须和先行词保持一致.
❖Anyone who _is_ over 20 can join the army。

❖I ,who __am__your friend , will help you.

Ⅱ关系副词的用法
When：指时间在从句中充当时间状语(=at/in/on /during which）
Where: 指地点在从句中充当地点状语(=in/at/to which）
Why: 指原因在从句中充当原因状语（=for which)
●I will never forget that day when I joined the party.
●This is the house where he was born。

●Tell me the reason why you were late this morning。

【注意】:
1.先行词是“时间名词” 关系词用which/that，作状语用或介词+ which.
①I'll never forget the days ______________we spent on that lonely island。

②I’ll never forget the day _______________I joined the Party.
2。

先行词是“地点名词”which/that，作状语用where或介词+ which.
①That is the factory __________ produces 100,000TV sets a year.
②That is the factory ________________his father once worked。

【补充】如果定语从句分别修饰point, situation，stage，condition和case等表示抽象意义的词，常用where 引导，意思是“到了某种地步，在某种境况中” ,where 在从句中充当状语。

1．I’ve come to the point where I can’t stand him.我已经到了无法容忍他的地步了.
2. The country is in t he situation where a war will break out at any time。

国家正处在随时有可能爆发战争的局势中。

3. 先行词是reason，关系词在从句中作状语用why或for + which.用which/that.
❖①This is the reason _________ he told me yesterday.
❖②This is the reason ______________he was late for the meeting。

4。

当主句主语是reason时,作主句表语的成分不能有because和because of 。

其结构一般为the reason why…is that…，或者the reason that … is that…，
1）The reason _____ he was absent was ______he was ill。

2）The reason ______ he told us for his absence is _____ he was ill.
A。

why/because B。

Ⅲ介词+关系代词（+which/whom/whose）
知识归纳:当关系代词作介词宾语,且该介词不是和从句的谓语动词构成固定短语时,介词可以提前，这样就出现"介词+关系代词”。

先行词指物，用"介词+which/whose”，指人则用"介词+whom/whose”, 且关系代词均不能省略.
1. The person _to whom____ I spoke just now is the manager that I told you about.
2. The pencil _with which___ he was writing broke.
3This is the boss _in whose___ company his elder sister is working.
▲如何判断介词
1）、看定语从句中动词与介词的固定搭配( 注意:动词短语不能拆开,即介词不能提前）
The gentleman ______ you told me yesterday proved to be a thief。

A. who
B. about whom
C. whom D。

with whom
The old man whom I am _looking after is better。

2)看定语从句中形容词与介词的固定搭配
He referred me to some reference books __with __ which I am not very familiar.
3)、根据先行词判断，所用的介词与先行词的固定搭配
He has not reached the age，__at__ which he can marry。

4）根据“介词+关系代词”在主从句中的作用及意义。

Water, __without which__ man can not live，is very important for us.
5)the+ 名词+of+关系代词
1）Recently I bought an ancient Chinese vase，___B__ was very reasonable.
A。

which price B。

the price of which
C. its price D。

the price of whose
2) This is the boy ___C __ the bike was stolen yesterday.
A. whom B。

whose C。

of whom D。

of whose
6）表示部分的词语＋of＋关系代词
知识归纳：此时，指人的关系代词只能是whom, 指事物的关系代词只能是which。

表示部分的词语常见的有：不定代词all，both，none，neither，either，some, any；数词（含基数词，序数词，分数和百分数);数词+名词；the +最高级/比较级;以及表示数目或数量的词语many, most, few, several，enough，half a，a quarter 等.

(同名异物)
考点2: such/so。

.as和such/so。

.that的用法辨异。

This is such an interesting book as we all like。

This is so interesting a book as we all like.
【解析】这是大家都喜欢的如此有趣的一本书。

（定语从句，as在从句中充当成分）
This is such an interesting book that we all like it.
This is so interesting a book that we all like it。

【解析】这本书如此有趣，大家都喜欢.（结果状语从句，that在从句中不充当成分)
【练习】
1. He is such a lazy man_____ nobody wants to work with______。

A. as; him
B. that；/
C. as；/
D. whom；him
2. Mrs。

A。

the same; as B。

the same; where
C. the same ; that D。

as the same；as
㈡as与which都可以引导一个非限制性定语从句，并代表前面整个句子.
The elephant is like a snake, as/which everybody can see.
不同的是:as引导的定语从句可以前置，而which不行。

As everybody can see, the elephant is like a snake
【注意】
1) 当从句的谓语是否定形式或表示否定意义时，只能用which.
He made a long speech at the meeting，__which__ we had not expected。

/ __which__ was un expected.
2）当从句的谓语后接一个复合宾语（宾补）时，只能用which.
He admires everyone in the class, __which___ I find quite strange。

3）which引导的从句与主句是__因果___关系或从句是对主句的__评论__，常解释为“__这,这一点___"，
Tom didn’t pass the exam，which made his parents very disappointed。

He must come from the north，which can be judged from his accent。

4）as引导的从句与主句是_一致__关系，as常解释为_____正如。

.。

的那样”, “ 正像。

.。

"。

如:as is known to all, as we all know, as has been said before, as was expected，as is said above，as is mentioned above，as is reported in the newspaper等
e。

g。

As is often the case, we have worked out the production plan.
【补充】
一：定语从句与强调句区别和混合
1。

It is the place ___where___ Luxun was born。

(定语从句）
2.It is in the place __that__ Luxun was born。

(强调句型）
二:定语从句与同位语从句
定语从句与前面的名词是修饰与被修饰的关系“……的（名词)”。

而同位语从句是用来说明前面名词的内容.与that从句同位的名词必须是一些表事实或概念的抽象名词，如fact, news, belief，truth, reply等。

that在定语从句中充当成分,而that在同位语从句中不充当任何句子成分，只起连接作用。

①We all have heard the news ___that____ our team won。

(同位语从句,that从句表示news的内容，that 在从句中不作任何成分)
②We don’t believe the news _that/ which/ 不填__ he told us yesterday.
（定语从句，that 作told 的宾语)
三：定语从句与表语从句
The place ____ the bridge is supposed to be built should be_____ the cross—river traffic is the heaviest.
A。

which; where B。

where; at which
C。

at which；where D。

which；in which
句子意思：建设大桥的地方应该是过河交通最拥挤的地方.第一空属于定语从句；第二空属于表语从句,而且结合语境此处缺少状语。

故此选择where。

四：定语从句与主语从句
① ___As___ is known to us all, paper was first made in China。

(as 引导定语从句,指代整个主句内容,可置于句首）
② ___It____ is known to us all that paper was first made in China.
(it 做形式主语,代替that 引导的主语从句）
五: 定语从句与状语从句
试比较:
①He left the key _____where______ he had been an hour before。

（where引导地点状语从句,相当于in the place where）
②He left the place __where/ in which___ he lived for many years。

(where 引导定语从句，修饰the place)
③ He is such a good teacher ____as_____ all of us love and respect。

(as 引导定语从句，as在从句中充当宾语）
④He is such a good teacher ____that___ all of us love and respect him。

（that引导结果状语从句，that在从句中不充当成分)
【难点突破】
一.疑问句中考查定语从句
e.g：Is this the farm___D__ you visited last week？
A. where B。

the one
C。

on which D./
【友情提示】最好的解决方法:还原法。

先把疑问句还原成陈述句，然后判断谁是先行词，再看关系词在定语从句中所充当的成分.
1。

Is this the hotel ____ he stayed last year？
A。

the one B。

that C。

where D。

which
2。

Is this hotel _____ he stayed last year?
A。

the one where B。

that C. the one D. which
二。

倒装句中考查定语从句
We came to a place，__D__ stood a big tower。

A. which
B. that
C./ D。

where
【友情提示】对于使用倒装语序的定语从句，应先把倒装语序还原成正常的语序.
三.拆分词组和固定搭配
The second is connected with the use __D__ the body makes of food.
A。

of which B。

where
C. to which D。

that
【友情提示】这类题解题的关键是把拆开的词组还原。

此句中被拆的词组是：make use of
1。

Why can not you realize the part _____ they have played in our life？
A. which B。

on which C. when D。

where
五。

插入非谓语动词
e。

g: Is this the man ___D___ you want to have _____ the radio for me.
A。

who，repaired B。

that，repaired
C. whom, repairing D。

that，repair
【友情提示】这类题的最好方法就是还原法。

此题可还原为：You want to have the man repair the radio for me。

1. The manager discussed the plan ____they would like to see ____ the next year.
A。

that, carried out B. who，carried out
C. which，carry out D。
