新課標(biāo)人教版高中英語語法+賓語從句的用法(共3頁)

1、精選優(yōu)質(zhì)文檔-傾情為你奉上一.賓語從句的定義置于動(dòng)詞、介詞等詞性后面起賓語作用的從句叫賓語從句。賓語從句的語序必須是陳述語序。謂語動(dòng)詞、介詞、動(dòng)詞不定式，v.-ing形式后面都能帶賓語從句。有些形容詞（afraid,sure,glad等）之后也可以帶賓語從句。二.賓語從句中引導(dǎo)詞的用法在復(fù)合句中作主句的賓語，引導(dǎo)詞有：連詞：that (that 常可省略),whether, if代詞：who, whose, what ,which副詞：when ,where, how, why 等。（一）that引導(dǎo)的賓語從句（在非正式場(chǎng)合that可以省略）可跟that從句做賓語的動(dòng)詞有：say, think

2、, insist, wish, hope, demand, imagine, wonder, know, suppose, see, believe, agree, admit, deny, expect, explain, order, command, feel, dream, suggest, hear, mean, notice, prefer, request, require, propose, declare, report等。例句：The boy believes that he will travel through space to other planets.注意事項(xiàng)：當(dāng)

3、主句謂語動(dòng)詞是 think, believe, suppose, expect 等詞，而賓語從句的意思是否定時(shí)，常把否定轉(zhuǎn)移至主句表示。例句：I dont think it is right for him to treat you like that.在以下情況中that不能省略1.當(dāng)句中的動(dòng)詞后接多于兩個(gè)由that引導(dǎo)的賓語從句時(shí)，第一個(gè)that可省，但后面的that不可省。例句：He said (that) you were too young to understand the matter and that he was asked not to tell you.2.當(dāng)主句的謂語動(dòng)

4、詞與that賓語從句之間有插入語時(shí)，that一般不可省。例句：Just then I noticed, for the first time, that our master was wearing his fine green coat and his black silk cap.3.當(dāng)that從句是雙賓語中的直接賓語時(shí)，that不可省。例句：I cant tell him that his mother died.注意事項(xiàng)：許多帶復(fù)合賓語的句子，that引導(dǎo)的賓語從句經(jīng)常移到句子后部，而用it作形式賓語。例句：I find it necessary that we should do t

5、he homework on time.（二）由whether,if 引導(dǎo)的賓語從句由whether(if)引導(dǎo)的賓語從句，實(shí)際上是一般疑問句演變而來的。意思是“是否”。賓語從句要用陳述句語序。一般說來，在賓語從句中whether與if可以互換使用，但在特殊情況下if與whether是不能互換的。例句：I wonder whether(if) they will come to our party.只能用whether，不能用if引導(dǎo)的賓語從句1.在帶to的不定式前例句：We decided whether to walk there. 2.在介詞的后面例句：Im thinking of wh

6、ether we should go to see the film.3.在動(dòng)詞后面的賓語從句時(shí)例句：We discussed whether we had a sports meeting next week4.直接與or not連用時(shí)例句：I cant say whether or not thet can come on time.只能用if不能用whether引導(dǎo)的賓語從句1.if引導(dǎo)條件狀語從句，意為“如果”例句：The students will go on a picnic if it is sunny.2.if引導(dǎo)否定概念的賓語從句時(shí)例句：He asked if I didnt

7、 come to school yesterday.3.引導(dǎo)狀語從句even if（即使）和as if（好象）時(shí)例句：He talks as if he has known all about it.（三）連接代詞和連接副詞引導(dǎo)的賓語從句這樣的賓語從句實(shí)際上是由特殊疑問句變化而來的，賓語從句要用陳述句語序。用于這種結(jié)構(gòu)的動(dòng)詞常常是：see, say, tell, ask, answer, know, decide, show, find out, imagine, suggest, doubt, wonder, discover, understand, inform, advise等。英語中

8、的連接代詞有：who,whom,whose,which,what,在句中擔(dān)任主語、賓語、定語或者表語。例句：Can you tell me whom you are waiting for?英語中的連接副詞有：when,where,why,how，在句中擔(dān)任狀語的成分。例句：None of us knows where these new parts can be bought.三.賓語從句的語序賓語從句的語序是陳述句語序即：連接代詞/副詞+主語+謂語+其他成分。例句如下：1.I dont know what they are looking for.2.Could you tell me w

9、hen the train will leave?3.Can you imagine what kind of man he is?四.賓語從句的時(shí)態(tài)1.主句是一般現(xiàn)在時(shí)，從句根據(jù)實(shí)際情況使用任何時(shí)態(tài)。例句：The headmaster hopes everything goes well.2.主句是過去時(shí)態(tài)，從句須用過去時(shí)態(tài)的某種形式。例句：She was sorry that she hadnt finished her work on time.3.當(dāng)賓語從句表示的是一個(gè)客觀真理或者事實(shí)時(shí)，即使主句是過去時(shí)，從句也用一般現(xiàn)在時(shí)態(tài)。例句：The teacher told his class

10、 that light travels faster than sound.五.賓語從句的特點(diǎn)1.賓語從句可以作及物動(dòng)詞、介詞及形容詞的賓語。2.賓語從句的語序一律用陳述句語序。3.連接詞that引導(dǎo)賓語從句在句中無詞義，不充當(dāng)句子成份，多數(shù)情況下可以省略。4.whether 和 if 都可引導(dǎo)賓語從句，但 whether后可緊跟or not；whether從句可作介詞的賓語。5.如果從句太長(zhǎng)，可以用形式賓語it. 贊同0時(shí)態(tài)主句是一般現(xiàn)在時(shí)，從句什么時(shí)態(tài)都行eg: He says that he is reading a book now. 主句是一般過去時(shí)，從句用過去范疇的時(shí)態(tài)eg：He said that he would work hardeg:They said the had been to France這兩個(gè)我舉的例子從句一個(gè)用的過去將來時(shí)。一個(gè)用的過去完成時(shí)。主句一般過去時(shí)，但是從句是客觀的真理，或者自然現(xiàn)象，還是一般現(xiàn)在時(shí)這個(gè)要注意，給你舉個(gè)例子eg：The students asked me if the earth goes round the sun.這是客觀真理。也是自然現(xiàn)象。這里的從句說的是地球圍繞太陽轉(zhuǎn)，這是永恒的真理，也是自然的現(xiàn)象，所以是一般現(xiàn)在時(shí)。其他的主句和從句中間的時(shí)態(tài)關(guān)系須看具體情況。還是給你舉幾個(gè)例子eg: M
