定語從句考點總結 1
定語從句考點總結
定語從句(Attributive Clauses)在句中做定語，修飾一個名詞或代詞，有時也可以修飾部分或整個句子。
被修飾的名詞，詞組或代詞即先行詞。定語從句通常出現在先行詞之后，由關系詞(關系代詞或關系副詞)引出。
關系代詞有：who, whom, whose, that, which, as。
關系副詞有：when, where, why, how。
關系代詞和關系副詞放在先行詞和定語從句之間，起連接作用，同時又可做定語從句的一個成分。當關系代詞做賓語時可以省略。
定語從句中的謂語動詞必須在人稱上和數量上和先行詞保持一致。
定語從句分為限制性定語從句和非限制性定語從句。
關系代詞引導的定語從句
1) who, whom, that 這些詞代替的先行詞是人的名詞或代詞，在從句中所起作用如下：
Is he the man who/that wants to see you?
(who/that在從句中作主語)
He is the man whom/ that I saw yesterday.
(whom/that在從句中作賓語)
2) whose 用來指人或物，(只用作定語，若指物，它還可以同of which互換).
例如：
Please pass me the book whose (of which) cover is green.
3) which, that 它們所代替的'先行詞是事物的名詞或代詞，在從句中可作主語、賓語等.
例如：
A prosperity which / that had never been seen before appears in the countryside.
(which / that在句中作賓語)
The package (which / that) you are carrying is about to come unwrapped.
(which / that在句中作賓語)
關系代詞that和which 都可以指物，that 和Who 都可以指人，其用法區別：
不用that的情況：
a) 在引導非限定性定語從句時
(錯)The tree, that is four hundred years old, is very famous here.
b) 介詞后不能用
We depend on the land from which we get our food.
c) 多用who 的情況
①關系代詞在從句中做主語
A friend who helps you in time of need is a real friend.
②先行詞為those, people 時
Those who were either fools or unfit for their offices could not see the cloth.
③先行詞為all, anyone, ones, one 指人時
One who doesnt work hard will never succeed in his work.
④在There be句型中There is a stranger who wants to see you.
⑤在被分隔的定語從句中
A new teacher will come tomorrow who will teach you German.
⑥在有兩個定語從句的句子中，其一用who，其二用that,但若先行詞后接兩個以上的并列定語從句時，后一個必須重復前一個關系代詞。
The student who was praised at the meeting is the monitor that is very modest and studies very hard.
There is a teacher who is always ready to help others and who enjoys what he does.
只能用that作為定語從句的關系代詞的情況
a)在不定代詞，如：anything, nothing, everything, all, much, few, any, little等作先行詞時，只用that，不用which。
All that is needed is a supply of oil.
Finally, the thief handed everything that he had stolen to the police.
b)先行詞有the only, the very, the just修飾時，只用that。
He is the very man that helped the girl out of the water.
c)先行詞為序數詞(the last)、數詞、形容詞最高級時，只用that。
The first English book that I read was "The Prince and the Pauper" by Mark Twin.
d)先行詞既有人，又有物時。
He talked about the teachers and schools that he visited.
e)當主句是以who 或which 開始的特殊疑問句時，用that 以避免重復。
Who is the person that is standing at the gate.
f)關系代詞在從句中做表語
He is not the man that he used to be.
關系副詞引導的定語從句
關系副詞可代替的先行詞是時間、地點、方式或理由的名詞，在從句中作狀語。
關系副詞when, where, why, how的含義相當于"介詞+ which"結構，因此常常和"介詞+ which"結構交替使用.
例如：
There are occasions when (on which) one must yield.
Beijing is the place where (in which) I was born.
Is this the reason why (for which) he refused our offer?
Im surprised the way how (by which) he works out the problem.
注意：
①在非限制性定語從句中，"介詞+ which"結構不能代替關系副詞。
如：They set up a state for their own , where they would be free to keep Negroes as slaves.
②含有介詞短語的動詞一般不能拆開，介詞仍放在動詞后面。
Is this the book which (that) she was looking for?
名詞/數詞/代詞 /形容詞最高級 + 介詞 + 關系代詞引導定語從句
She has written a book , the name of which I have forgotten.
There are fifty-five students in our class , all of whom are working hard.
There are five continents in the world , the largest of which is Asia.
as, which 引導非限定性定語從句的差別
由as, which 引導的非限定性定語從句，as和which可代整個主句，相當于and this或and that。As一般放在句首，which在句中。
As we know, smoking is harmful to ones health.
The sun heats the earth, which is very important to us.
as可引導非限制性從句，常帶有“正如”的意思。
As is know, smoking is harmful to ones health.
用法區別：
(1) as 引導的定語從句可置于句首，而which不可。
As we all know, he never smokes.
(2) as 代表前面的整個主句并在從句中作主語時，從句中的謂語必須是系動詞;若為行為動詞，則從句中的關系代詞只能用which。
(3)非限定性定語從句中出現expect, think, suppose 等表示猜測、想象、預料等時。
She succeeded in her doing the research work , as we expected.
(4)As 的用法 the same? as; such?as 中的as 是一種固定結構, 和??一樣??。
I should like to use the same tool as is used here.
We should have such a dictionary as he is using.
定語從句考點總結 2
定語從句（Attributive Clauses）在句中做定語，修飾一個名詞或代詞，被修飾的名詞,詞組或代詞即先行詞。定語從句通常出現在先行詞之后，由關系詞（關系代詞或關系副詞）引出。
關系代詞有：who, whom, whose, that, which等。
關系副詞有：when, where, why等。
關系代詞引導的`定語從句
關系代詞所代替的先行詞是人或物的名詞或代詞，并在句中充當主語、賓語、定語等成分。關系代詞在定語從句中作主語時，從句謂語動詞的人稱和數要和先行詞保持一致。
1）who, whom, that
這些詞代替的先行詞是人的名詞或代詞，在從句中所起作用如下：
Is he the man who/that wants to see you?
他就是你想見的人嗎？（who/that在從句中作主語）
He is the man whom/ that I saw yesterday.
他就是我昨天見的那個人。（whom/that在從句中作賓語）
2） Whose 用來指人或物，（只用作定語, 若指物，它還可以同of which互換）, 例如：
They rushed over to help the man whose car had broken down. 那人車壞了，大家都跑過去幫忙。
Please pass me the book whose （of which） cover is green. 請遞給我那本綠皮的書。
定語從句考點總結 3
修飾名詞或者代詞的從句叫做定語從句。被修飾的名詞或者代詞叫先行詞；定語從句的引導詞叫關系詞（關系代詞&關系副詞）；定語從句分為限定性定語從句和非限定性定語從句（前有逗號隔開）
引導定語從句的關系代詞有：that which who whom whose as
關系副詞有：when where why：
1. that 與which 在指代物時的用法區別
that 和which都可以引導先行詞為物的`定語從句，但是用法有區別：
① 只能用that的五種情況
a. 先行詞為不定代詞或先行詞由不定代詞修飾時
b. 先行詞前有最高級或序數詞修飾時
c. 先行詞即有人又有物時
d. 先行詞前有the very, the only修飾時
e. 主句為which,或who 引導的特殊疑問句時
② 只能用which的兩種情況
a. 非限定性定語從句中
b. 介詞之后引導定語從句時
2．which與as的區別
as 和which 都可以引導非限制性定語從句，三種情況下只能用as，不能用which
a. as置于句首引導定語從句時（As we know,…）
b. as 含有“正如”之意（…as we expected）
c. 先行詞前有such, the same 修飾時（…such an easy question as the little boy can answer.）
3. who、whom、that 的區別
a.先行詞為those或people 時，常用關系代詞who,不用that
b.介詞之后用關系代詞whom引導定語從句
4. whose 用法
whose+n. 引導定語從句的結構是定語從句的一個考查熱點，此結構可以換成是the+n.+of+which引導定語從句或者可以換成是of which +the+n.
e.g.The man pulled out a gold watch, the hands of which were made of small diamonds.
whose hands / of which the hands
5. 介詞+關系代詞引導定語從句的用法
a. 介詞之后的關系代詞只能用which（先行詞為物）或者是whom（先行詞為人）
b. 介詞的選擇方法有三個原則：一“先”二“動”三“意義”
I lost my pen, with which I took notes. (先行詞為pen,使用鋼筆用with)
This is the house in which he lives. (定語從句中謂語動詞live為不及物動詞)
The gas is oxygen without which we can’t live. (根據句意決定)
6. 先行詞為way時
先行詞為way，在定語從句中作狀語時，用that，in which引導定語從句，也可以省略關系詞。
e.g. I don’t like the way(that/in which) he speaks to his parents.
7. 關系副詞when、where、when引導定語從句的具體用法
① 先行詞表示時間、地點、原因時，在定語從句中作狀語，選擇相應的關系副詞when、where、why引導定語從句。若其在定語從句中作主語或賓語，則選擇關系代詞引導定語從句。區別三組例句：
when my brother was a little boy.
b. I still remember the time
that/which we spent together.
why he was late.
c. This is the reason
that/which he gave us.
②某些非地點時間名詞有定語從句修飾，關系詞在從句中作狀語，由where引導定語從句（stage, case, point, situation）；同樣用法的還有occasion,由when引導定語從句。
e.g. I can think of many cases where students know a lot of words but don’t write a good essay.
There are many occasions when people don’t know what they want.
8. 定語從句中的謂語動詞
關系代詞在定語從句中作主語時，定語從句中的謂語動詞應該與先行詞保持一致。
e.g. Anyone who wants to have a holiday puts up your hand.
Those who want to have a holiday put up your hand.
This is one of the students who have passed the exam.
This is the only one of the students who has passed the exam.
9. 區分定語從句和其他句型
①區別于簡單句和并列句
It is in the classroom (where we have classes) that the meeting will be held.
(定語從句修飾先行詞the classroom)
(強調句型，強調部分為介詞短句in the classroom)
③區別于同位語從句
that she had passed the exam （同位語從句：對名詞解釋說明）
The news excited us.
that he told us （定語從句：對名詞修飾限定）
④區別于狀語從句
Do you know the time when the class is over? (定語從句，有先行詞)
Let’s play games when the class is over.（時間狀語從句，無先行詞）
Put the book where it belongs. (地點狀語從句，無先行詞)
10. 定語從句中關系詞的省略
定語從句中，作賓語的關系代詞可以省略，介詞之后的關系代詞不可省略。
This is the house which he lives in. (√)
This is the house he lives in. (√)
This is the house in which he lives. (√)
This is the house in he lives. (×)
定語從句考點總結 4
一、省去作主語的關系代詞致錯
誤：The changes have happened in the past few years make the city look even more beautiful.
正：The changes that have happened in the past few years make the city look even more beautiful.
誤：Those want to visit the art exhibition sign your names，please.
正：Those who want to visit the art exhibition sign your names，please.
分析：關系代詞在定語從句中作賓語時可以省，但作主語時不能省。
二、從句中使用多余的代詞或副詞致錯
誤：The compositions we handed them in two weeks ago haven’t been marked yet.
正：The compositions we handed in two weeks ago haven’t been marked yet.
分析：從句中省去了作賓語的關系代詞that或which，應去掉them。
誤：After living in Paris for 60 years，he returned to the small town where he grew up as a child there.
正：After living in Paris for 60 years，he returned to the small town where he grew up as a child.
分析：關系副詞where在從句中作地點狀語，使用there屬語義重復，應去掉。
三、as / it / which混用致錯
誤：As is known to all that smoking does great harm to health.
正：It is known to all that smoking does great harm to health.或As is known to all，smoking does great harm to health.
分析：as引導非限制性定語從句，置于句首時，要用逗號與主句隔開;it放在句首，作形式主語時，將從句后置，中間不用逗號。
誤：Tom drinks a lot every day，as his wife doesn’t like at all.
正：Tom drinks a lot every day，which his wife doesn’t like at all.
分析：as引導的非限制性定語從句既可放在主句后，也可放在主句前和主句中，而which引導的非限制性定語從句只能放在主句后。當主句與從句語義一致時，通常用as，反之則用which。
四、從句中誤用人稱代詞或物主代詞致錯
誤：China has hundreds of islands，the largest of them is Taiwan.
正：China has hundreds of islands，the largest of which is Taiwan.或China has hundreds of islands，and the largest of them is Taiwan.
分析：人稱代詞只能用在獨立的單句或分句中，不能用在定語從句中。
誤：The boss in her department Ms King worked looked down upon women.
正：The boss in whose department Ms King worked looked down upon women.
分析：物主代詞不能在定語從句中作定語，定語從句中用whose作定語，修飾department。
五、關系代詞與關系副詞混用致錯
誤：I live in Hong Kong，where is the Special Administrative Zone.
正：I live in Hong Kong，which is the Special Administrative Zone.
誤：Is this museum the one when some German friends visited the other day?
正：Is this museum the one that some German friends visited the other day?
分析：關系代詞在定語從句中作主語、賓語、表語或定語，關系副詞在從句中作狀語。
六、用 ing結構替換定語從句致錯
誤：The girl bringing milk here every morning is from a mountain village.
正：The girl who brings milk here every morning is from a mountain village.
誤：The scholars returning from abroad recently were awarded by the local government.
正：The scholars who had returned from abroad recently were awarded by the local government.
分析：當定語從句的謂語動詞表示經常性或習慣性的動作或定語從句謂語動詞的.動作先于主句謂語動詞的動作時，不宜用v.?鄄ing替換定語從句。
七、that與which混用致錯
誤：The weather turned out to be very good，that was more than we expected.
正：The weather turned out to be very good，which was more than we expected.
誤：The stories about the Second World War were written，of that this is one example.
正：The stories about the Second World War were written，of which this is one example.
分析：that和which使用情況有別，不可混淆。在非限制性定語從句中及介詞后要使用which。下列情況須用that：1.先行詞為something/anything/everything/nothing/all/much/little等;2.先行詞被形容詞最高級、序數詞修飾;3.先行詞被all/the/very/the only等修飾;4.先行詞既有人，又有物時。
八、 謂語動詞的人稱和數與先行詞不一致致錯
誤：I，who is your close friend，will certainly help you when in trouble.
正：I，who am your close friend，will certainly help you when in trouble.
分析：定語從句謂語動詞的人稱和數應與先行詞保持一致。
誤：This is the only one of the tape?鄄recorders in the sound lab that don’t need repairing.
正：This is the only one of the tape?鄄recorders in the sound lab that doesn’t need repairing.
分析：one前有the only修飾，因此one為先行詞，從句謂語動詞用單數does’t need。
九、限制性定語從句與非限制性定語從句區分不清致錯
誤：Abraham Lincoln who led the American people through these years was shot at a theatre in Washington，D. C.
正：Abraham Lincoln，who led the American people through these years，was shot at a theatre in Washington，D. C.
分析：限制性定語從句對先行詞起修飾、限定的作用，非限制性定語從句對先行詞進行補充說明。當先行詞為專有名詞或表示“唯一”事物時，要用非限制性定語從句。
十、固定搭配不當致錯
誤：The house was sold at such a low price that people hadn’t expected.
正：The house was sold at such a low price as people hadn’t expected.
分析：先行詞前若有such/the same/as/so等詞修飾時，從句須用as引導。先行詞前若有形容詞比較級修飾時，從句一般用that引導。
定語從句考點總結 5
考點：
定語從句的引導詞，包括關系代詞that，which，who，whom，whose。可以在定語從句中充當主語，賓語和表語成分，whose則充當定語。代人的有：who，whom，whose，that;代物的有：that，which，whose。另外還有關系副詞，包括when(指時間)，where(指地點)，why(指原因)，在定語從句中作狀語。要注意的是，選擇關系副詞還是關系代詞要看先行詞在定語從句中充當什么樣的成分。
限制性定從和非限制性定從，限制性定從修飾某個名詞或者名詞短語或者代詞，與先行詞之間不用，隔開。但是非限制性定從不僅可以修飾某個名詞，還可以修飾整個句子，與先行詞之間常用，隔開。而且非限制性定從不能用that引導。
as引導的非限定從和which引導的區別也是考點之一，which不能放在句首，但是as既可以放在句首，也可以放在中間的`。which引導的非限定從常翻譯成“這”，as引導的則常翻譯成“正如”
還有就是只能用that作為關系代詞的情況，這個情況挺多的，比如先行詞被only，very,序數詞或者形容詞最高級(等等，情況較多，需要平時多積累總結)修飾時。
另外，介詞+關系代詞中考查介詞的選擇，應該按照短語的習慣性搭配和先行詞來。
比如，Who is the girl with whom you just shook_hands?(shake hands with…是習慣性搭配)
而當關系代詞作為動詞+介詞短語的賓語時，短語不能拆開。
比如， He is a kind of man whom you can safelydepend_on.
定語從句誤區提醒：
1)當表示時間或地點的名詞作先行詞時，要判斷出它們在從句中作狀語還是主語或賓語。作狀語時用關系副詞，反之用關系代詞。
典型例題：I can never forget the day _______ we worked together and the day ______ we spent together.
A. when; which B. which; when C. what; that D. on which; when
答案：A
解析：兩個先行詞the day都是表示時間的名詞,但第一個空白處要填的關系詞在從句中作狀語,因此要用關系副詞when. 第二個空白處要填的關系詞在從句中作動詞spent的賓語,因此要用關系代詞which或that來引導定語從句.
2)當主語為物時，不能用what
3)there be句型中，指人用who指物用that。
4)當主句中缺少主語或表語時，用the one。
5)當出現先行詞+介詞時，關系詞只能用whom或which
6)當出現先行詞+介詞時，注意判斷介詞與從句謂語是否有關系，以確定為定語從句
定語從句考點總結 6
I. 定語從句起了形容詞的作用，在句中修飾一個名詞或代詞。被修飾的詞叫做先行詞，引導定語從句的詞叫關系詞，他的作用一是放在先行詞與定語從句中間起了連接作用，二是在從句中擔當一個成分，并與先行詞保持數的一致。
關系詞先行詞從句成分
例句
關系代 詞who人主語Do you know the man who is talking with your mother？whom， which和that在從句中做賓語時，常可以省略，但介詞提前時后面關系代詞不能省略，也不可以用that
whom人賓語Mr. Smith is the person with whom I am working
The boy (whom) she loved died in the war..
whose人或物定語I like those books whose topics are about history.
The boy whose father works abroad is my deskmate.
that人或物主語，賓語A plane is a machine that can fly.
She is the pop star (that) I want to see very much.
which物主語，賓語The book (which) I gave you was worth $10.
The picture which was about the accident was terrible.
as人或物主語，賓語He is such a person as is respected by all of us.
This is the same pen as I lost yesterday.as做賓語一般不省略
關系副 詞when時間時間狀語I will never forget the day when we met there.可用on which
where地點地點狀語This is the house where I was born.可用in which
why原因原因狀語I can’t imagine the reason why he turned down my offer.可用for which
II. that與which， who， whom的用法區別情況用法說明
例句
只用that的情況1.先行詞為all， everything， anything， nothing， little， much，等不定代詞時
2.先行詞被all， any， every， each， much， little， no， some， few等修飾時
3.先行詞有形容詞最高級和序數詞修飾時
4.先行詞既指人又指物時
5.先行詞被the only， the very修飾時
6.句中已經有who或which時，為了避免重復時1.He told me everything that he knows.
2.All the books that you offered has been given out.
3.This is the best film that I have ever read.
4.We talked about the persons and things that we remembered.
5.He is the only man that I want to see.
6.Who is the man that is making a speech？
只用which， who， whom的情況1.在非限制性定語從句中，只能用which指代物，用who/whom指人
2.在由“介詞+關系代詞”引導的定語從句中，只能用which指物，whom指人。
3.先行詞本身是that時，關系詞用which， 先行詞為those， one， he時多用who。
1.He has a son， who has gone abroad for further study.
2.I like the person to whom the teacher is talking.
3.Those who respect others are usually respected by others.
III. as、which和that的區別
從句區別
限制性
定語從句中名詞前有such和the same修飾時，關系代詞用as，不能用whichHe is not such a fool as he looks.
Don’t read such books as you can’t understand.
非限制性
定語從句中as和which都可以指代前面整個主句。如果有“正如，象”的含義，并可以放在主句前，也可以放在后面，那么用as；而which引導的從句只能放主句后，并無“正如”的意思。They won the game， as we had expected.
They won the game， which we hadn’t expected.
As is well known， he is a famous film star in the 1980s.
the same... as和
the same ...thatthe same... as指同類事物
the same ...that 指原物That’s the same tool as I used last week.(同類工具，不是同一把)
That’s the same tool that I used last week.那就是我上周用過的工具。
注意：the way 做先行詞時，定語從句可由that， in which 引導或不用引導詞。
IV.定語從句與其它從句(句型)的區別
類別區別
定語從句與并列句：定語從句與并列句的主要區別在于：并列句有像and，but，so等并列連詞或兩個句子用分號連接，這時就不能再用引導定語從句的關系詞了。 ①Mr Li has three daughters，none of _____ is an engineer.
②Mr Li has three daughters，but none of _____ is a dancer.
從結構上看，①小題是定語從句，故填whom；
②小題有并列連詞but，是并列句，故填代詞 them。
定語從句與狀語從句：定語從句的前面有名詞作先行詞，而狀語從句沒有先行詞。 This is the place where we used to live a few years ago.
這是幾年前我們居住的地方。(定語從句，先行詞為the place)
Let’s go where we can find a better job.
我們到能找到更好的工作的地方去吧。(地點狀語從句)
定語從句修飾、限制、說明名詞，只能放在先行詞的后面，而狀語從句說明動作發生的情況，并且可以放在主句的前面。 Do you know the time when the class is over？ 你知道下課的`時間嗎？(定語從句)
It was already five o’clock when the class was over.
=When the class was over， it was already five o’clock.
當下課時己經是5點了。(時間狀語從句)
When， where和why在引導定語從句時可以用“介詞+which”的結構來替換，在引導狀語從句時卻不行。 This is the factory in which (where) his father once worked.
這就是他的父親曾經工作過的那個工廠。(定語從句)
Put back the book where it was. 把書放回原處。(狀語從句)
定語從句中的關系詞在從句中充當某種句子成分，因此去掉它則從句成分不完整；而結果狀語從句中的連接詞在從句中不作任何成分，去掉后從句的成分仍然完整。 It is such an interesting book as we all like. 它是我們大家都喜歡的如此有趣的書。
(as用作動詞like的賓語，它引導的是定語從句)
It is such an interesting book that we all like it.
它是一本如此有趣的書，我們大家都喜歡它。
(that不充當句子成分，故它引導的是結果狀語從句)
定語從句與同位語從句：定語從句在復合句中相當于形容詞，對先行詞起修飾、描述或限制的作用，與先行詞之間有從屬關系。同位語的作用相當于名詞，對前面的名詞給予補充說明或進一步解釋，是前面名詞的具體內容，與先行詞之間是同位關系。 The news that she had passed the exam made her parents very happy.
她考試及格的消息使她父母親很高興。(同位語從句)
此句中的同位語從句 The news that she had passed the exam
可以改寫成表語從句：The news is that he passed the exam.
The news that he told us interested all of us.
他告訴我們的消息使大家都感興趣。(定語從句)
The news that he told us 是定語從句，此句不能改寫為：The news is that he told us.
定語從句與強調句：強調句的結構為“It is/was+被強調部分+that+從句”。被強調部分可以是除謂語以外的任何成分，當被強調部分是人時，還可用who代替that。這一句型中，一定不能因為被強調部分是表時間或地點的詞就用when或where代替 that。 ①It is on the morning of May 1st _____ I met Liang Wei at the airport.
②It is the factory _____ Mr Wang works.
從結構上看：
①小題是強調句，故填 that。

1、限制性定語從句：從句與主句關系密切，去掉從句，主句意義不完整，甚至不合邏輯。
e.g. I was the only person in our office who was invited.（去掉定語從句，意思就不完整）

e.g. As I expected, he got the first place again in this mid-term examination. 正如我所預料的那樣，他在這次期中考試中又獲得了第一名。
3）as 引導非限制性定語從句時與which的區別

e.g. He made a long speech, as we expected.
He made a long speech, which was unexpected.
②當非限制定語從句為否定時，常用which引導。
e.g. Tom drinks a lot every day, which his wife doesnt like at all.

e.g. The sick man whom she is looking after is her father.
6. 介詞在關系代詞前，只能用which和whom，且不能省略；介詞在句尾，關系代詞可有which, that, whom, 口語中也可用who，且可省略。
