定語從句是中學(xué)英語教學(xué)的語法重點(diǎn)，也是高考熱點(diǎn)，現(xiàn)歸納如下。
考點(diǎn)一：考查關(guān)系代詞which引導(dǎo)的定語從句
1.which 引導(dǎo)的非限制性定語從句。
1）Dorothy was always speaking highly of her role in the play ,_____ ,of course ,made the others unhappy.(NMET2000)
A.who B.which C.this D.what
解：這道題考查which 引導(dǎo)的非限制性定語從句，從句被插入語of course所割開，答案選B.
2）：Whenever I speak to him, _____was fairly often ,he would talk on and on without giving me a chance to speak.
A. which B. what C. that D.when
解：可以把題目還原成Whenever I speak to him, he would talk on and on without giving me a chance to speak, ____ was fairly often.很容易判斷這是由which 引導(dǎo)的非限制性定語從句，答案選A.
注意：which引導(dǎo)非限制性定語從句，指代整個(gè)句子時(shí)，有可能置于句中，將指代的完整的句子分割開。
考點(diǎn)二：考查關(guān)系代詞as引導(dǎo)的定語從句.
1. as引導(dǎo)的限制性定語從句。
例如：These houses are sold at such a low price _____people excepted.(Shanghai 2000 spring)
A. like B. as C .that D. which
解：這道題考查是such -----as 句型在定語從句中的運(yùn)用，答案選B。
注意：關(guān)系代詞as在限制性定語從句中常運(yùn)用于句型such -----as 和the same ----as----句型。
2. as引導(dǎo)的非限制性定語從句。
例如：_____is known to everybody, the moon travels around the earth once every month.(NMET 2001)
A.It B.As C.That D.What
解：這道題要求學(xué)生搞清楚兩個(gè)句型It is known to everybody that ------（everybody knows that------）和As is known to everybody ( as指代整個(gè)句子the moon travels around the earth once every month) 的區(qū)別。答案選B.
思考：which和as作為關(guān)系代詞引導(dǎo)定語從句有何區(qū)別？
（1） as 作為關(guān)系代詞，引導(dǎo)非限制性定語從句，起先行詞必須是整個(gè)句子，而Which作為關(guān)系代詞，引導(dǎo)非限制性定語從句， 其先行詞既可以是整個(gè)句子也可以是名詞
（2） 當(dāng)as和which都指代整個(gè)句子時(shí)，as可以置于主句的前、中、后,位置較靈活；但which 不能引導(dǎo)定語從句置于句首。
考點(diǎn)三：考查關(guān)系代詞whose 的用法。
例如：1)Have you seen the film “Titanic”, ______leading actor is world famous? (Shanghai 2000 spring )
A.its B.it’s C. whose D.which
解： 這道題考查這一考點(diǎn)：whose 在定語從句中充當(dāng)定語，其先行詞為物，(等同于所修飾的名詞+of which)。原句可以轉(zhuǎn)化成：Have you seen the film “Titanic”, the leading actor of which is world famous? 答案選C.
2) His parents wouldn’t let him marry anyone ____family was in the country.
A. of whom B. whom C. of whose D. whose
解：這道題考查這一考點(diǎn)：whose 在定語從句中充當(dāng)定語，其先行詞為人，(等同于所修飾的名詞+of whom)。原句可以轉(zhuǎn)化成: His parents wouldn’t let him marry anyone, the family of whom was in the country.答案選D.
注意：whose 在定語從句中充當(dāng)定語時(shí)，其先行詞既可以為人也可以為物。
考點(diǎn)四：考查關(guān)系副詞where
例如：He’s got himself into a dangerous situation _____he is likely to lose control over the plane. (Shanghai 2001)
A.where B.which. C.while D.why
解：在這一定語從句中，其先行詞不是表示一個(gè)具體地點(diǎn)的名詞，而是一個(gè)抽象名詞situation。那么這道題考查where 在從句中表示抽象概念的情況，其常見的先行詞有 situation，point, position ,condition 等。
考點(diǎn)五：考查關(guān)系副詞when
例如：1）The film brought the hours back to me ____I was taken good care of in that far –away village. (NMET 2001)
A. until B. that C. when D. where
解：這道題 when 作為關(guān)系副詞，引導(dǎo)限制性定語從句，.意為“-----的時(shí)候”。常用的先行詞有moment,day, time ( hour, week, month, year)。
2）It was an exciting moment for these football fans this year, ______ for the first time in years their team won the World Cup.(2000 spring)
A.that B.while C.which D.when
解：從從句的意思“這是他們隊(duì)多年來第一次贏得世界杯”�？梢酝浦簭木涫菍�(duì)表示時(shí)間的先行詞加已說明，先行詞是an exciting moment，所以這道題考查 when 作為關(guān)系副詞，引導(dǎo)非限制性定語從句，.意為“在那時(shí)”“屆時(shí)”。
考點(diǎn)六：非謂語動(dòng)詞在定語從句中的運(yùn)用。
例如：1）The manager discussed the plan that they would like to see ____ the next year.(NMET 2000)
A. carry out B. carrying out C. carried out D. to carry out
解：可以把原句這一復(fù)雜句轉(zhuǎn)化為兩個(gè)簡單句
1． The manager discussed the plan.
2． They would like to see the plan carried out the next year.很顯然，運(yùn)用了see sth done 這個(gè)結(jié)構(gòu)。所以選C.
2)A-------- The electrical fan she ________in town yesterday works well again.
B-------- Thanks to the repairman ,it does work well again.
A. repaired B. had repaired C. has repaired D. had had repaired
解：這道題解題的關(guān)鍵在于分析句子的成分。A句可以分解為
1) The electrical fan works well again.
2) She had it repaired in the town yesterday. 很顯然have sth done 這個(gè)詞匯運(yùn)用其中，所以選B.
由此可見，只要學(xué)生在平時(shí)加以歸納和總結(jié)，定語從句這個(gè)考點(diǎn)一定會(huì)不難攻破。
