定語從句考點清單 定語從句的基本用法一 定語從句的基本知識1定義：定語從句在句中做定語，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(xiàn)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。2. 定語從句的位置: 定語從句的位置只能放在它所修飾詞的后面。 Tom, who is 17, is my classmate.Tom is my classmate, who is 17. 3定語從句的結構: 被修飾的名詞 / 代詞 + 關系代詞 + 從句 “被修飾的名詞/代詞”= “先行詞” 這兒要強調的是先行詞只能是名詞或代詞4定語從句的分類: 限定性定語從句與非限定性定語從句 見清單 P89 一二、關系代詞的用法1. 關系代詞which, that的用法which（指物，作賓語可省略, 如介詞提前則不能省略，）, that（指人/物，作賓語可省略）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。例如：A prosperity which / that had never been seen before appears in the countryside. 農(nóng)村出現(xiàn)了前所未有的繁榮。（which / that在句中作主語）The package （which / that）you are carrying is about to come unwrapped. 你拿的包快散了。（which / that在句中作賓語）注意：定語從句中，只能用關系代詞that或只能用關系代詞which 的情況： 見清單P90 二、（二）2.當關系代詞后面帶有插入語時, 只能用whichHere is the English grammar which, as I have told you, will help improve your English.避免重復當先行詞為that時或一個句子中有兩個定語從句，其中一個用了that，另一個宜用whichThat which you borrowed is out of date.I bought some magazines that might help me to kill time and which I could pass on to others when I finished them.2. 關系代詞who, whom, whose的用法見清單 P90 二、（一）1，2 指人時，宜用who的情況（4點） 非限定性定語從句中指人的時候，只能用who 避免重復。如先行詞為that/those時 如果先行詞是one, ones, anyone, anybody, everyone, everybody, someone, somebody時,關系代詞應該用 who 或whom There be結構中，修飾主語的定語從句宜用whoTheres a gentleman who wants to see you.3. 介詞+關系代詞引導的定語從句 介詞后面的關系詞不能省略。that前不能有介詞。 1）見清單P91，（三），1 2）見清單P91，（三），2 a. The man (to whom you talked just now) will chair the meeting tomorrow.= The man (whom/who you talked to just now) will chair the meeting tomorrow.但注意，在固定短語中介詞不能提前，比如：care for, call on, put off, listen to, look for, look after等，如果把它們拆開，那么這些短語就失去了原來的含意。The old man whom I am looking after is better. b. He told me the tickets are hard to buy, in which case youd better buy right now. (which作case的定語)（He told me the tickets are hard to buy, and youd better buy right now in that case. ）c. The books, some of which he has read, are very interesting. 表示整體與部分關系（The books are very interesting and he has read some of the book.）d. The students, most of whom have seen the movie, are from our class.（The students are from our class and most of them have seen the movie.）e. He spent 2 hours there, during which time he slept.（He spent 2 hours there and he slept during that time.）f. The boss in whose department Mr. King worked had a heart attack.（The boss had a heart attack. Mr. King worked in his department.）3）復合介詞短語+關系代詞which的倒裝P91，（三），3a.I arrived at a building， in front of which grow many trees.=I arrived at a building, and many trees grow in front of it.b.We visited a hill，at the foot of which lies a temple.=We visited a hill, and a temple lies at the foot of it.c.They went into the classroom， in the center of which stands a large table.=They went into the classroom, and a large table stands in the center of it.4）介詞+which/whom +不定式結構見清單P91，（三），4He sold his gold watch and got twenty pounds with which to buy his wife a birthday gift.4. 關系代詞as引導的定語從句見清單P91，（四）P91，二（一），3關系代詞as (as as, such as, the same as/that) 可放于句首和句中，可作從句主語、賓語和狀語（做題時一般看到前面有as, such, the same等，大部分情況后面都選as） Take as many books as you can. I want to read such a book as you read. (as定語從句)This is such a good book that we all like it. (so/suchthat結果狀語從句，that后跟完整的句子)Please do it in the same way as I did. (as作狀語)I want to borrow the same book as you read. 我想借一本和你讀的一樣的書。I want to borrow the same book that you read.我想借你讀的那本書。（只有一本） 5. 關系代詞as, which 的區(qū)別 見清單P91，（四）4與as區(qū)別：前面發(fā)生的事產(chǎn)生后面結果用which as一般為泛指，“正如”三 關系副詞的用法1. 表時間、地點、原因的先行詞在從句中作狀語時，關系詞使用關系副詞。 When 表時間 = 介詞 + which Where 表地點 = 介詞 + which Why 表原因 = for which 例如： I still remember the day on which/when I joined the League. 表時間 This is the room in which/where I stayed for the night.表地點 This is the reason for which/why he was late. 表原因2. 判斷關系代詞與關系副詞 方法一： 用關系代詞，還是關系副詞完全取決于從句中的謂語動詞。及物動詞后面無賓語，就必須要求用關系代詞；而不及物動詞則要求用關系副詞。例如：This is the mountain village where I stayed last year. 這是我去年待過的山村。Ill never forget the days when I worked together with you.我永遠不會忘記與你共事的日子。 判斷改錯： （錯） This is the mountain village where I visited last year. （錯） I will never forget the days when I spent in the countryside.習慣上總把表地點或時間的名詞與關系副詞 where, when聯(lián)系在一起。此兩題錯在關系詞的誤用上。 方法二： 準確判斷先行詞在定語從句中的成分（主、謂、賓、定、狀），也能正確選擇出關系代詞/關系副詞。例1. Is this museum _ you visited a few days age? A. whereB. that C. on which D. the one例2. Is this the museum _ the exhibition was held. A. whereB. that C. on whichD. the one答案：例1 D，例2 A3. 介詞+where/when見清單P92(二)四定語從句其他用法要點（特殊句型及注意點）（一）定語從句的主謂一致：見清單P92 四 （二）特殊的定語從句1the way+定語從句，the way做從句狀語時，通常用that/in which/省略The way (that/in which) he is doing the experiment is very funny. 2It/Thisis+the+序數(shù)詞+時間+ (that) +定語從句（從句用完成時）It/Thisisthefirsttime（that）Ihavebeenhere.3It is (high) time +that+定語從句It is time that we should go home. It is time that we went home 4but作為關系代詞（了解即可），相當于that(who) notThere are very few but admire his talents. 很少有人不佩服他的才華。(三) 定語從句需特別注意的地方1 situation, case, point, stage在從句中充當狀語時，后常用where見清單P92 三（三）Can you think of a situation where(= in which) you can use the word?The accident had reached to a point where both their parents are to be called in. 2 標點符號，比較以下一組句子：I picked up the apples. Some of them were bad.I picked up the apples; some of them were bad.I picked up the apples and most of them were bad.I picked up the apples, some of which were bad.3 分裂式定語從句：有些定語從句的先行詞和關系詞之間會插入一些其它成份。He arrived in Jinzhou in 1984, where he became a manger 2 years later. 此句中關系詞不能用when，因為從句中已經(jīng)有時間狀語，因此先行詞不是1984，而是Jinzhou。4帶有插入語的定語從句，如I think, do you suggest等。Please choose someone who you think is kind. 此句中you think為插入語，關系代詞who作從句的主語，is是從句的謂語。5定語從句和同位語從句的區(qū)別。定語從句的先行詞或關系代詞要在從句中充當一定的句子成份，而同位語從句中則不充當任何句子成份，比較以下兩個句子。The news that our team lost the game disappointed all of us. 此句為同位語從句，the news在從句中不充當任何句子成份。The news that you told me yesterday is so disappointing.此句為定語從句，the news在從句中充當賓語。6定語從句和狀語從句的區(qū)別，狀語從句沒有先行詞，引導詞用where，它很明顯的特點是其前面為動詞、副詞等，有時雖有名詞但不是表示地點的名詞。You should make it a rule to leave things where you can find them again.狀從After the war a new school building was put up where there had once been a theatre. (狀語從句)This is the room where/in which we lived three years ago.定從7定語從句和強調句的區(qū)別強調句型的結構：It is / was (could be) + 被強調的成分 + that .強調的成分是主語、賓語和狀語。強調句型可用“還原法”來判斷，若刪除強調句型結構后，句子能還原為一個完整的句子，就是強調句。It was at the school gate that I met Tom yesterday. It was the school gate where I met Tom yesterday.第一句為強調句，去掉強調句型結構后，句子可以還原成一個完整的句子，I met Tom yesterday at the school gate. 而第二句不能還原成一個完整的句子，必須要加個介詞at。8as前置和It作形式主語的主語從句混淆這兩種形式主要區(qū)別在于as結構有標點符號“，”號，而It和that連用，比較下面兩個句子：As is known to all, the earth moves around the sun.It is known to all that the earth moves around the sun. 五 定語從句練習中的難點除了以上的幾點需特別注意外，定語從句練習中還要小心下面的情況： 陷阱題。1. 從句迷惑主句結構的判斷The person we spoke to _ no answer at first Amaking Bmakes Cmake Dmade對于此題，一些粗心的學生看到to馬上就選擇C。實際上we spoke to是定語從句，修飾the person，主句的主干應該是The person made no answer.應該選D。The man whose songs we are fond of _ in our city next week Asinging Bto sing Cwill sing Dsang同樣，此題易誤選A，以為是be fond of singing，實際上whose songs we are fond of 為定語，句子主干為The man will sing in our city.2. 主句從句結構混雜在一起Everything he _ away from him before he returned to his hometown. A. took B. had been taken C. had had been taken D. had taken此句對于一些基礎差的學生有一定難度，他們無法正確判斷句子的結構，容易誤選A或D。但實際上，此題是主句和從句的結構相互混雜。Everything為先行詞，he had為定語從句修飾everything，主句主干為Everything had been taken away. 因此應選C。3定語從句和強調句混雜在一起定語從句和強調句本身就容易混淆，如果把兩者加在一起就更容易混淆了，做題時，關鍵是要判斷定語從句的范圍。如以下這個句子：It was in this building _ I once worked _ he met his former classmate.It was in this building (where I once worked) that he met his former classmate.
