3、. She is a beautiful girl.She is a beautiful girl who drives me crazy.二、知識講解（一）定語從句定義1、定語從句：在復(fù)合句中，修飾某個名詞或代詞的句子（做這個名詞或代詞的定語）叫定語從句，定語從句一般放在被修飾的名詞或代詞后面。2、先行詞：被修飾的名詞或代詞叫做定語從句的先行詞。3、關(guān)系詞：用來引導(dǎo)定語從句的詞叫做關(guān)系詞。關(guān)系代詞的種類：關(guān)系代詞：that, which, who, whom, whose, as關(guān)系副詞：when, where, why 4、定語從句結(jié)構(gòu)：先行詞+關(guān)系詞+定語從句。a、There she s

4、aw a wall of water that was quickly advancing towards her.b、 In Japan, someone who sees another person making the gesture will think it means money.c、Visitors can go on exciting rides where they can feel what it is like to do the things they have seen their heroes do in the movie.d、Oprah Winfrey is

5、a black woman whose rise to fame is an inspiring story.（二）定語從句分類限定性定語從句：從句對先行詞進(jìn)行必要的描述或說明，對先行詞起修飾限定作用，從句與先行詞緊密相連，缺少它則句義顯得不完整，一般不用逗號隔開。非限定性定語從句：對先行詞進(jìn)行補(bǔ)充說明，解釋，它與先行詞關(guān)系松散，用逗號隔開。1、The man who gave me this book is Tom .(限定性)2、Tom,who is reading a book ,is my classmate (非限定性)（三）關(guān)系代詞1、who指人，在定語從句中作主語。e.g. Th

6、e man who is sitting under the tree is a German .2、Whom指人，在句中做賓語，可省略，但在做介詞的賓語是只能用whom,不能用who。關(guān)系代詞前有介詞時不能省略。e.g. I know the girl (whom) the teacher is speaking to . I know the girl to whom the teacher is speaking .3、whose, 作定語，可指人或物 e.g. Everyone heplps the child whose parents are dead.They are the l

7、azy students whose homework wasnt handed in .4、that 指人或物，多指物，作主語（不能省略）或賓語（可省略） e.g. He is the finest comrade that has helped us . This is a plant that grows in the north .5、which ,指物，在句中做主語（不能省略），或賓語（可省略）。e.g. This is a plant which grows in the north .常用that不用which的情況1、當(dāng)先行詞是all, everything, anything

8、, nothing, much, little, none, one等不定代詞時，只用that。歌訣助記：不定代詞這路貨，全用that準(zhǔn)沒錯。 Pay attention to everything that I do.2、當(dāng)先行詞被序數(shù)詞或形容詞最高級修飾時，只用that。歌訣助記：先行詞前被限定，千萬不要用which。 This is the best novel (that)I have read.3、如果出現(xiàn)兩個或兩個以上的先行詞，并同時兼指人和物時，關(guān)系代詞用that。歌訣助記：兩項并列人與物，引導(dǎo)定從用that。They were talking about the person

9、and things that they remembered in school.4、當(dāng)先行詞被the only, the last, the way, the same等修飾時。 This is the last time that I shall give you a lesson.5、在疑問詞which開頭的特殊疑問句中，為了避免重復(fù)只用that。 Which of the students that knows something about history.6、當(dāng)被修飾的成分是數(shù)詞時，（被修飾成分是代名詞one，指人時除外）只用that. Ive got one that you

10、might be interested in.常用which，不用that的情況1、引導(dǎo)非限制性定語從句。Football, which is an interesting game, is played all over the world.全世界都踢足球，它是一項有趣的運(yùn)動。2、直接放在介詞后作賓語時（介詞+關(guān)系代詞結(jié)構(gòu)中）。Language is the most important tool without which people cant communicate with each other.語言是最重要的工具，沒有它，人們便無法交流。（四）關(guān)系副詞1、when 指時間（1）在定

11、語從句中作狀語，先行詞主要為一些時間名詞（year ,day ,time,week等）,但時間名詞在從句中作主語，賓語時，應(yīng)用that，which，不能用when e.g. Ill never forget the time when (during which ) we worked on the farm.作狀語 I still remember the day that/which is his birthay.做主語 He regretted the days that /which he spent on play . 做賓語（2）It is the first time that

12、句型中，that是習(xí)慣用法，不用when。 e.g. It is the first time that I have been to the Great Wall .2、where 指地點 （1）指前面的地點，在從句中作狀語。e.g. I know the factory where I worked twenty years ago . （2）指地點，在句中作主語，賓語時不能用where，須用that/which .e.g. This is the house where he has lived for 20 years （作狀語）.This is the house that he h

13、as lived in for 20 years .（作賓語）e.g. This is the shool in which /where we study every year.（作狀語） This is the shool that /which we visited yesterday. （作賓語）. （3）當(dāng)先行詞為某個方面、情況、階段、位置等的詞時使用關(guān)系副詞3、why 表示原因“the reason why .that. ”中，不能用because 代替that .e.g. Thats the reason why (for which ) he didnt come to sch

14、ool .The reason why he didnt attend the meeting is that he was ill .但reason 在從句中做賓語時，關(guān)系代詞用that/which ,可省略e.g. I dont believe the reason (which/that) he gave me .（五）“介詞+關(guān)系代詞”引導(dǎo)的定語從句 當(dāng)先行詞在定語從句中作介詞的賓語時，往往可以把介詞放在關(guān)系代詞之前，構(gòu)成“介詞+關(guān)系代詞（whom/which）”結(jié)構(gòu)。但一些短語如look after 等中的介詞不能與動詞分開，故不能放在關(guān)心代詞之前。確定介詞時： 一是，依據(jù)定語從句中

15、動詞所需要的某種習(xí)慣搭配； 二是，依據(jù)先行詞的某種習(xí)慣搭配； 三是，根據(jù)所要表達(dá)的意思來確定。e.g. Thats the reason why (for which ) he didnt come to school .（六）非限定性定語從句關(guān)系代詞在非限定性定語從句中的用法。指人做主語用who,作賓語用whom ，指地點用where，指時間when，指物只用which，不能用that，作定語用whose。e.g. He didnt see the film, which was very interesting .(不用that)（七）as 引導(dǎo)的限制性定語從句A . such .as 和

16、 the sameas 的用法such .as： 像.一樣的，像.之類；the sameas： 和.同樣的 在這兩個句型中，as是關(guān)系代詞，such和same 作定語，修飾主語里的某個名詞（或代詞），這個名詞是由as引導(dǎo)的定語從句的先行詞，as在從句中可擔(dān)任主語、賓語或表語。Eg： We have found such materials as are used in their factory.( 在從句中作主語) I seldom give my students such a difficult problem as they cannot work out.（在從句中作賓語） The

17、result is not the same as they had expected.( 在從句中作賓語)重點比較 :the same as和 the same thatthe sameas:和.相同（代指同類事物）；the same that：和.相同（代指同一事物）兩者都引導(dǎo)定語從句。as 從句中說明的名詞與the same 修飾的名詞是同一類，而非同一個。that從句中說明的名詞與the same 修飾的名詞是同一個。Eg：He is reading the same book that you bought yesterday.He is reading the same book

18、as you bought yesterday.This is the same pen that I lost. =This is the pen that I lost.(指同一支筆)This is the same (kind/type/sort) of pen as I lost.（指同類型的筆，但并不是我丟失的那一支）B. .such as 的用法.such as 中的such為代詞，意思是“這樣的人或物”，as 在從句中作賓語，修飾先行詞such。Eg： This book is not such as I expect.He told me of his experience s

19、uch as I had never had before.相關(guān)鏈接：such as 還有“諸如，例如，像那樣的”的意思，此時后面跟名詞或名詞短語等。Eg：They bought a lot of fruit, such as apples,oranges,etc.（八）as 引導(dǎo)的非限制性定語從句as 可以像which一樣引導(dǎo)非限制性定語從句，用來代表整個句子的內(nèi)容，它的先行詞可以是名詞，也可以是不定式短語或整個句子。as 在從句中作主語、賓語和表語。此外，有些as 引導(dǎo)的定語從句已成為固定用法，如：As we know As has been said before 如上所述As is k

20、nown to all As is often the case 像通常那樣As is reported As was expected 正如預(yù)料的那樣Eg： She is very careful, as her work shows. As we know, smoking is harmful to ones health. As is often the case, we have worked out the production plan.重點比較：as 和which 引導(dǎo)的非限制性定語從句的聯(lián)系和區(qū)別1、as 和which 都可以代替整個句子，當(dāng)定語從句置于主句之后時，as和wh

21、ich可以和互換。Eg：He didnt tell me any news, as/which upset me.2、Which引導(dǎo)的從句，代表的前面的整個主句時，不能放在主句之前。而as 引導(dǎo)的定語從句，代表整個主句時，可以放在主句之前或之后，有時也可以放在主語和謂語之間。Eg：As is reported in the newspapers, talks between the two countries are making progress. = Talks between the two countries, as is reported in the newspapers, are

22、 making progress.As與that的區(qū)別 As 引導(dǎo)的定語從句表示它的內(nèi)容與主句所講的內(nèi)容相似，即指同類事物；that 引導(dǎo)定語從句表示的內(nèi)容與主句相同，即為同一事物。e.g. This is the same pen that I lost yesterday .這正是我昨天丟的鋼筆。 This is the same pen as I lost yesterday .這正像我昨天丟的鋼筆。（九）同位語從句與定語從句區(qū)別1、同位語從句和定語從句結(jié)構(gòu)相似，通常位于某一名詞或代詞之后，但兩者存在明顯區(qū)別：同為語從句對名詞性成分加以補(bǔ)充說明，是該名詞性成分具體內(nèi)容的體現(xiàn)（相當(dāng)于名詞的

23、作用）。That 引導(dǎo)的同位語從句中引導(dǎo)詞that不在該同位語從句中充當(dāng)成分，但不能被省略，同位語從句還可以用whether,how等連詞引導(dǎo)（定語從句則不能）。定語從句對先行詞加以限制或修飾，說明先行詞的性質(zhì)或特征（相當(dāng)于一個形容詞的作用），定語從句的引導(dǎo)詞均在該定語從句中充當(dāng)成分（that在其引導(dǎo)的限定性定語從句中充當(dāng)主語，賓語或表語，充當(dāng)定語從句的賓語，that可以省略）注意體會一下三組例句。（1） 第一組 We cant solve the problem how we can travel faster than light .我們解決不了如何才能超過光的速度這個問題。 I cant

24、 remember the problem that they have.我記不得他們的問題了。（2） 第二組 I wont believe the fact that he lied to his mother.我不愿相信他對他母親撒謊的事實 I wont believe the fact (that) he told me .我不愿相信他告訴我的事實。（3） 第三組 The news that Tom would go abroad is told by him. 湯姆將出國的消息是他講的。The news that he told me is that Tom would go abro

25、ad next year.他告訴我的消息是湯姆來年將出國。三、例題精析例題1.【2011全國卷I】The prize will go to the writer _ story shows the most imagination.
