定語(yǔ)從句總結(jié)
總結(jié)是在一段時(shí)間內(nèi)對(duì)學(xué)習(xí)和工作生活等表現(xiàn)加以總結(jié)和概括的一種書面材料，它可以幫助我們總結(jié)以往思想，發(fā)揚(yáng)成績(jī)，不如靜下心來(lái)好好寫寫總結(jié)吧。但是總結(jié)有什么要求呢？以下是小編精心整理的定語(yǔ)從句總結(jié)，歡迎閱讀，希望大家能夠喜歡。
定語(yǔ)從句總結(jié)
定語(yǔ)從句由關(guān)系代詞who、whom、whose、which、what、as和關(guān)系副詞where、when、why等引導(dǎo)，但須記�。�
1.what不能引導(dǎo)定語(yǔ)從句.
2.關(guān)系詞的分析須考慮它在定語(yǔ)從句中的成分。
一.指人的關(guān)系代詞有who、whose、whom、that. 試分析：
The old man who/whom /that we visited yesterday is a famous artist.
Miss Wang is taking care of the child whose parents have gone to Beijing .
The man with whom my father shook hands just now is our headmaster. (=The man who/whom that my father shook hands with just now is our headmaster.)注：
A. 指人時(shí)有時(shí)只用who不宜用that。
1.先行詞為one、ones或anyone
(1)The comrade I want to learn from is the one who studies hard and works hard.
(2)Anyone who breaks the law should be punished.
2.先行詞為these時(shí)
These who are going to Beijing are the best students of our school.
3.在there be 開(kāi)頭的句子中
There is a student who wants to see you.
4.一個(gè)句子中帶有兩個(gè)定語(yǔ)從句，其中一個(gè)定語(yǔ)從句的關(guān)系代詞是that，另一個(gè)宜用who，以免重復(fù)。
The student that won the first prize is the monitor who works hards.
5.在非限制性定語(yǔ)從句中
A.I met a friend of mine in the street, who had just come from Japan.
B.主句以who開(kāi)頭的句子中,只用that,不用who。
二.指物的關(guān)系代詞有which、whose(=of which)、that. 試分析：
1. I like the books which / that were written by Lu Xun.
2. The desks (which/that) we made last year were very good.
3. This is the house in which we lived last year. (= This is the house which /that we lived in last year.)
4. I live in the room whose windows face south. (= I live in the room ,the windows of which face south.)
注：
A. 介詞如果位于作為其賓語(yǔ)的關(guān)系代詞之前時(shí)，只能用whom、 which不能用who或that.
(1). The girl about whom they were talking is our monitor.
(2). The book in which there are many interesting things was written by Li Ming.
B. 部分短語(yǔ)動(dòng)詞中的介詞不可與動(dòng)詞拆開(kāi)，在定語(yǔ)從句中其介詞不可前置，只能放在其動(dòng)詞之后。
Is this the book which she is looking for?
The old man who/whom they are waiting for is Professor Li.
The child who/whom she is looking after is Wang Ping’s son.
C. 指物時(shí)，下列情況下只能用that ，不宜用which。

I have told them all (that) I know.
All that can be done has been done.

(3)先行詞是形容詞最高級(jí)或被最高級(jí)修飾時(shí)。

(4)如果有兩個(gè)或兩個(gè)以上分別表示人和物的先行詞時(shí)(先行詞既有人又有物)，定語(yǔ)從句的關(guān)系代詞用which和who都不合適，只能用that。

(3)that，Those作主語(yǔ)時(shí)

限制性定語(yǔ)從句與非限制性定語(yǔ)從句的區(qū)別：
限制性定語(yǔ)從句
非限制性定語(yǔ)從句
All the students who study hard have passed.學(xué)習(xí)努力的學(xué)生都考試及格了。(只有努力的及格了，不努力的沒(méi)及格。) All the students ,who study hard have passed.所有的學(xué)生都及格了，他們學(xué)習(xí)努力。(沒(méi)有人不及格，這些學(xué)生都很努力。)
從句是先行詞不可缺少的定語(yǔ)(如去掉，主句意思就不完整或不正確。) 從句是對(duì)先行詞的附加說(shuō)明(如去掉，主句意思仍清楚，不受影響。) 與主句關(guān)系密切，不用逗號(hào) 與主句關(guān)系不十分密切，用逗號(hào)與主句隔開(kāi)譯為漢語(yǔ)時(shí)，從句譯在先行詞前，與先行詞用“的”連接 譯為漢語(yǔ)時(shí)，從句放在主句后面關(guān)系代詞that可以代替who、whom(指人)、which(指物) 關(guān)系代詞不用that,只用who、whom(指人)、which(指物) 關(guān)系代詞代替賓語(yǔ)時(shí)可以省略 關(guān)系代詞不能省略關(guān)系代詞as和which
先研究下面兩個(gè)例句：
○1.This elephant is like a snake, as /which everybody can see. =As everybody can see, this elephant is like a snake. 任何人都看得出來(lái)，這頭象像條蛇。
○2.Tom didn’t pass the physics exam, which made his parents very angry. Tom物理考試不及格，這使得他父親很生氣。
這兩個(gè)例句中，as和which所代表的都是整個(gè)主句所表示的內(nèi)容。但有兩點(diǎn)不同之處：
1. 在形式上as引導(dǎo)的非限制性定語(yǔ)從句可位于主句的后面，也可位于主句的前面;而which引導(dǎo)的非限制性定語(yǔ)從句只能位于主句的后面，不能位于主句的前面。
2. 在意義上，as引導(dǎo)的定語(yǔ)從句和主句的關(guān)系一般為一致關(guān)系，常譯為“正如……”，“就像……”，而which引導(dǎo)的定語(yǔ)從句和主句的關(guān)系是因果關(guān)系，或which引導(dǎo)的定語(yǔ)從句是對(duì)主句的評(píng)論。因此，在意思通順的情況下，which可代替as，而as許多時(shí)候不能代替which，如句○2。再如：
1.He was late again, as / which we had expected. =As we had expected, he was late again. 正如我們所料，他又遲到了。/他又遲到了這是我們?cè)缇土系降摹?/p>
2. The street hasn’t been cleared for weeks, which makes it very dirty. 街道好多星期沒(méi)有打掃了，因此整條街很臟。(不用as)
3.The young man cheated his friend of much money, which was disgraceful. 那年輕人詐騙了他朋友許多錢財(cái)，這是不光彩的。(不 用as)
4.He takes exercise everyday, which has done a lot of good to his health. 他每天運(yùn)動(dòng)，這對(duì)他的身體很有好處。(不用as)
5.As has already been pointed out, English is rather difficult for a foreigner. 正如已經(jīng)指出的那樣，英語(yǔ)對(duì)于初學(xué)者說(shuō)，是相當(dāng)難學(xué)的。在such…as…、the same…as…、 as…、 as many…/much as…等結(jié)構(gòu)中,as不能用which代替。如：
1.Such books as this are too difficult for beginners. 這樣的書對(duì)于初學(xué)的人來(lái)說(shuō)是太難了。
=Books such as this are …
=Books like this are …
2.I live in the same building as he (does). 我和他住再同一座大樓里。
3.He knows as many people as are present at the meeting. 他認(rèn)識(shí)所有到會(huì)的人。
4.That day we all got up early as usual. 那天我們和平時(shí)一樣，都起得很早。
“One of the +復(fù)數(shù)名詞”后面定語(yǔ)從句中謂語(yǔ)單復(fù)數(shù)情況
這一結(jié)構(gòu)后面的定語(yǔ)從句的謂語(yǔ)動(dòng)詞通常用復(fù)數(shù)形式，跟定語(yǔ)從句所*近的那個(gè)復(fù)數(shù)名詞在數(shù)上保持一致。如：
1. That is one of the books that are required for study at school.
2. This is one of the most wonderful novels that have been published since 1990.
3. She is one of the few persons who know Spanish .
4. This is one of the most famous plays that were written in the thirties,
如果one of +復(fù)數(shù)名詞這一結(jié)構(gòu)前面帶有the only、the very之類的限定語(yǔ)，后面定語(yǔ)從句的謂語(yǔ)動(dòng)詞則要用單數(shù)形式，這是因?yàn)槎ㄕZ(yǔ)從句在意義上修飾的是而不是那個(gè)復(fù)數(shù)名詞。如：
1.He is the only one of the teachers who knows French in our school.( 修飾the only one)
He is one of the teachers who know French in our school.( 修飾the teachers)
2.This is the only one of the rooms that is free now. (修飾the only one)
This is one of the rooms that are free now. (修飾rooms)
as與which引導(dǎo)的定語(yǔ)從句
兩者均可引導(dǎo)非限制性定語(yǔ)從句，有時(shí)可以互換，但下列情況多用as。
1. 關(guān)系代詞引導(dǎo)的定語(yǔ)從句居句首時(shí)。 As we all know, the earth is round.
2. 當(dāng)與such或the same連用時(shí)，一般用as。 Such books as you tell me are interesting. I have the same plan as you.
3. 當(dāng)從句和主句語(yǔ)義一致時(shí)，用as，反之則用which。 She has married again, as was expected. She has married again, which was unexpected.
4. as在從句中作主語(yǔ)時(shí)，后面常接行為動(dòng)詞的被動(dòng)語(yǔ)態(tài)，如be known，be said，be reported等，如從句中行為動(dòng)詞是主動(dòng)語(yǔ)態(tài)，一般要用which作主語(yǔ)。
She has been late again, as was expected.
Tom has made great progress, which made us happy.
定語(yǔ)從句小知識(shí)
首先，了解什么是定語(yǔ)從句。
定語(yǔ)從句是一種用句子作定語(yǔ)，修飾名詞或代詞的主從復(fù)合句，通常直接跟在被修飾名詞或代詞之后，被修飾的名詞或代詞稱為先行詞，試論定語(yǔ)從句。定語(yǔ)從句一般由關(guān)系代詞或關(guān)系副詞來(lái)引導(dǎo)，關(guān)系代詞或關(guān)系副詞一方面連接定語(yǔ)從句，另一方面其本身又在定語(yǔ)從句中充當(dāng)某個(gè)句子成份。
eg：She is a girl who just cant say no. girl 為先行詞，who just cant say no 為定語(yǔ)從句，關(guān)系詞who 在整個(gè)定語(yǔ)從句中作主語(yǔ)。
常見(jiàn)的關(guān)系代詞who(whom)指人、that 指人或物、whose，關(guān)系副詞when、where以及why、how。關(guān)系代詞在定語(yǔ)從句中可作主語(yǔ)、賓語(yǔ)、定語(yǔ)、表語(yǔ)，關(guān)系副詞在定語(yǔ)從句中作狀語(yǔ)。
eg：
(1)He laughs best who laughs last.(who 在定語(yǔ)從句中作主語(yǔ))
�。�2）David is the boy whom /who you have talked to. (who/whom作定語(yǔ)從句的賓語(yǔ))
（3）This is the window whose glass is broken.(whose作定語(yǔ))
�。�4）Tell me the reason why you are late.(why 在定語(yǔ)從句中作狀語(yǔ))
到底用關(guān)系代詞還是關(guān)系副詞，就看定語(yǔ)從句中缺少什么，如果缺少主語(yǔ)、賓語(yǔ)、定語(yǔ)就用關(guān)系代詞，如果缺少狀語(yǔ)就用關(guān)系副詞。
其次，應(yīng)注意定語(yǔ)從句中的謂語(yǔ)動(dòng)詞一般應(yīng)與先行詞保持人稱和數(shù)的一致。
eg：This is the only one of the students who is from Canada.
先行詞 單數(shù)
定語(yǔ)從句中的動(dòng)詞時(shí)態(tài)應(yīng)根據(jù)句意及上、下文而定，主句和從句可用不同的時(shí)態(tài)。
eg:Where is the comrade whom I saw yesterday.
現(xiàn)在時(shí) 過(guò)去時(shí)
第三，定語(yǔ)從句，分為限制性定語(yǔ)從句和非限制性定語(yǔ)從句。
限制性定語(yǔ)從句是先行詞在意義上不可缺少的定語(yǔ)，關(guān)系十分密切，如果省去主句的意思就不完整，該從句不能用逗號(hào)和主句分開(kāi)。
eg:That is a man who found my handbag.
非限制性定語(yǔ)從句是先行詞和整個(gè)主句的附加說(shuō)明，關(guān)系不是十分密切，若省去，主句的意思仍然清楚，該從句前常用逗號(hào)和主句分開(kāi)。
eg：She was a good mother, who loved her children very much.
需要注意引導(dǎo)非限制性定語(yǔ)從句指事或物時(shí)只用which。
eg：The trees near the house, which I planted three years ago, are growing up well.
第四，運(yùn)用定語(yǔ)從句中的關(guān)系代詞或關(guān)系副詞要注意以下幾點(diǎn)：
1.介詞＋關(guān)系詞（即關(guān)系代詞在定語(yǔ)從句中作介詞的賓語(yǔ)，如果介詞放在關(guān)系代詞的前面，則關(guān)系代詞指人只能用whom，指事或物只能用which。）
who is the comrade with whom you shook hands just now?
The boy lives in the house in front of which there is a tall building.
當(dāng)然，當(dāng)介詞放在從句的句末時(shí)，關(guān)系代詞的用法不受以上限制。
2.關(guān)系代詞that 可指人也可指物，但在下列情況下一般用that 引導(dǎo)，不用which/who。
1)當(dāng)先行詞為nothing, anything, everything, all, much, little, none, few，等不定代詞時(shí)常用that，但something可用which。
eg：I can give you all that I can get.
2)當(dāng)先行詞被only, last 等修飾時(shí)常用that。
eg：This is the only picture that is inter esting.
3)當(dāng)先行詞被數(shù)詞、形容詞最高級(jí)來(lái)修飾時(shí)常用that，不用which。
eg：That is the longest river that runs through our village.
4)主句中有兩個(gè)先行詞，且一個(gè)表示人，另一個(gè)表示物，即先行詞同時(shí)有人或物時(shí)常用that。
eg：We talked about the persons and the things that had never happened in school.
人 物
關(guān)系代詞本身在定語(yǔ)從句中用作表語(yǔ)，用that引導(dǎo)定語(yǔ)從句，但that 常省略。
eg:Our hometown is no longer the place that it used to be.
6)若句中有兩個(gè)定語(yǔ)從句，前一個(gè)定語(yǔ)從句已用了關(guān)系代詞which，則第二個(gè)定語(yǔ)從句中的關(guān)系代詞常用that。
eg： Edison set up a factory which produced things that had never seen before.
