1、初中英語語法定語從句精講精練.doc 定語從句 在復(fù)合句中修飾名詞或代詞的從句叫做定語從句。有限制性定語從句和非限制性定語從句。被修飾的名詞或代詞叫先行詞。引導(dǎo)定語從句的關(guān)系代詞有 who，whom，whose，which，that，as 等和關(guān)系副詞 where，when，why 等。關(guān)系代詞和關(guān)系副詞在定語從句中充當(dāng)一定的句子成分。 1、由 who，who，whom，whose 引導(dǎo)的定語從句 在這類定語從句中，who 用作主語，whom 用作賓語(可以省略)，whose 用作定語。如： This is the man who is looking for you. The actor （

2、whom）you"re talking about is in the car. Do you know the singer whose name is Liu Huan? 2、由 which 引導(dǎo)的定語從句 which 在定語從句中作主語、或謂語動詞或介詞的賓語(可以省略)。如： The bridge which is being built is 5km long. This is the CD (which) he wants. The house in which /where they live is very beautiful. 注： whom 和 which 作介詞

3、賓語時，介詞一般可放在它們之前，也可以放在從句原來的位置上；在含有介詞的動詞固定詞組中，介詞只能放在原來的位置上。如： The house in which they live is very beautiful. (=The house which they live in is very beautiful.) Lina is the girl with whom I went shopping yesterday. (=Lina is the girl whom I went shopping with yesterday) The actor （whom）you"re tal

4、king about is in the car. 如果是引導(dǎo)非限制性定語從句，只能用關(guān)系代詞 which，而不能用 that。如： She has lost the book HARRY POTTER, which she likes very much. 3、由 that 引導(dǎo)的定語從句 that 在定語從句中可以指人或物，作主語或謂語動詞的賓語(可以省略)，不能作介詞的賓語（which 才能作介詞的賓語）。如： The toy car that was given by my uncle last week is my favourite. The present (that) I go

5、t last week was given by my uncle. 在以下幾種情況下都只能用 that 引導(dǎo)定語從句： 1）先行詞是不定代詞 all，few，little，much，something，nothing，anything 等。如： All that you have to do every day is to practise speaking more. 2）先行詞被序數(shù)詞或形容詞最高級所修飾的。如： I"ll never forget the first lesson that was taught by Mr He. That"s the most i

6、nteresting movie (that) I have ever seen. 3）先行詞被 all，any，every，each，few，little，no，some 等修飾的。如： Have you finished reading all the books (that) I brought you a month ago? 4）先行詞被 the only，the very，the same，the last 等修飾的。如： Miss Sun was the only person (that) I knew at the party. 5）先行詞既有人又有物時。如： At the

7、party we talked about things and persons (that) we were interested in. 6）當(dāng)句中已有 who 時，為了避免重復(fù)。如： Who is the girl that is wearing a red dress? 7）用作關(guān)系副詞，修飾表示時間的名詞如 day，time，moment 等，代替 when。如： The story happened on the day that/when he left his hometown. 4、由 where，when，why 引導(dǎo)的定語從句。如： Do you know the rea

8、son why he was late for school yesterday? I"ll never forget the day when I joined the Party. This is the hospital where he was born twenty years ago. 當(dāng)先行詞表示時間或地點時，關(guān)系詞有時用 when，where，有時要用 that/which，這主要看它 在定語從句中作什么成分而定。如： October 1st, 1949 is the day when new China was founded. (狀語) October 1st,

9、1949 is the day (that) we should remember forever. (賓語) This is the hospital where he was born twenty years ago.（狀語） This is the hospital that was built twenty years ago. (主語) 5、限制性定語從句和非限制性定語從句 1）限制性定語從句是句中不可缺少的組成部分，主句和從句之間不用逗號隔開。引導(dǎo)限制性定語從句的有關(guān)系代詞 who，whom，whose，which，that 等和關(guān)系副詞 where，when，why 等。 2）

10、非限制性定語從句是對主句先行詞的補充說明，沒有它也不影響主句意思的完整性。通常用逗號把主句和從句分開，關(guān)系代詞只能用 which，而不用 that；指人時，要用 who/whom。如： He has two brothers, who are both pupils. There are 160 teachers in their school, 97 of whom are women teachers. She has lost the book HARRY POTTER, which she likes very much. 6、as 引導(dǎo)的定語從句 1）as 用作關(guān)系代詞和關(guān)系副詞引導(dǎo)

11、限制性定語從句，在從句中作主語、賓語或狀語，構(gòu)成 the same.as.，such.as.等結(jié)構(gòu)。如： I like the same sport as he does. (as 作賓語) Please do it in the same way as they did. (as 作狀語) Do you want to buy such a computer as she bought? (as 作賓語) 2）as 引導(dǎo)非限制性定語從句，在從句中作主語、賓語或表語。從句說明整個句子，可以放在句首。如： As we all know, Taiwan belongs to China from

12、the ancient time. (as 代表整個句子，作賓語) As is known to all, Anne is the top student in her class. (as 代表整個句子，作主語) English is very important, as indeed it is. (as 代表整個句子，作表語) 這種類似插入語的句式通常有：as is said above，as is already mentioned above，as is known to all，as it is，as is often the case ，as is reported in the

13、 newspaper 等。 注： 關(guān)系代詞在從句中作主語時，從句的謂語動詞的人稱和數(shù)必須和先行詞保持一致； 關(guān)系代詞 whom，which，that 在限制性定語從句中作動詞的賓語或介詞的賓語（該介詞沒有提前）時，常常省略，但是 as 一般不能省略。 關(guān)系代詞 which 和 as 在定語從句中的區(qū)別是：which 不能放在句首，而 as 卻可以；在句中時，as 有"正如、就象'的含義，而 which 則無此意。 Ex.1: Choose the best answer: 1.
