初中英語(yǔ)語(yǔ)法賓語(yǔ)從句講解專(zhuān)項(xiàng)練習(xí)及答案

1、精選優(yōu)質(zhì)文檔-傾情為你奉上 初中英語(yǔ)語(yǔ)法賓語(yǔ)從句講解 小口訣：賓語(yǔ)從句三注意，時(shí)態(tài)語(yǔ)序引導(dǎo)詞；主句一般現(xiàn)在時(shí)，從句不需受限制；主句一般過(guò)去時(shí)，從句須用相應(yīng)時(shí)；陳述轉(zhuǎn)化that引，一般疑問(wèn)用if/whether,特殊問(wèn)句疑問(wèn)詞，引導(dǎo)詞后陳述式。一基本講解 來(lái)源：直接引語(yǔ)變間接引語(yǔ)概念:在句中擔(dān)當(dāng)賓語(yǔ)的從句叫賓語(yǔ)從句。 Eg: He said,“I am good at drawing”.He said he was good at drawing. (動(dòng)詞賓語(yǔ))1.引導(dǎo)詞 (1) that引導(dǎo)賓語(yǔ)從句時(shí)，通常用陳述句充當(dāng), that可省略。Eg: She said,“I want to go t

2、here ” She said (that) she wanted to go there.(2) whether 或 if 引導(dǎo)的賓語(yǔ)從句,由一般疑問(wèn)句/選擇疑問(wèn)句充當(dāng)，陳述語(yǔ)序。Eg: “Are you interested in geography?” she said. She asked if/whether I was interested in geography.I wonder if /whether she has told the new to Li Lei . Im not sure whether he will come or not.注意：一般情況下，whethe

3、r 和if 可以互用， 但有些情況例外a. 介詞短語(yǔ)后只用whether 不用ifeg: We are talking about whether we'll go on the panic. b. 引導(dǎo)詞與動(dòng)詞不定式或or not 連用時(shí)，只用whether. eg:I cant say whether or not he will come on timec. if當(dāng)如果講時(shí),引導(dǎo)的是條件狀語(yǔ)從句，表示如果，不能用whether. Eg: If you want to be a good teacher, it will take times. Whether you can su

4、cceed depends on how much effort you pay.(3). 特殊疑問(wèn)詞引導(dǎo)賓語(yǔ)從句時(shí)，不可省略，陳述句語(yǔ)序。特殊疑問(wèn)詞為：how , when, where, why ,which whose.E.g. What do you want? He asked. He asked me what I wanted. I have no idea where he is now. I dont know how to deal with it. He asked whose handwriting is the best in the class.2.賓語(yǔ)從句時(shí)態(tài)a.

5、主句為一般現(xiàn)在時(shí)，從句不受主句的限制eg: Do you know if/whether he has seen the film?Im sorry to hear that your father is ill.She says she is going to go to Beijing next week.He tells me that his sister came back yesterday.b.當(dāng)主句是一般過(guò)去時(shí)，從句用過(guò)去的相應(yīng)某種時(shí)態(tài)She didnt know why the boy was late again. (過(guò)去一般)I didn't know if/wh

6、ether he had seen the film.（過(guò)去完成）I wondered when she was going to America.（過(guò)去將來(lái)）注意：當(dāng)主句是一般過(guò)去時(shí)，而從句表示的是客觀(guān)真理，自然現(xiàn)象，科學(xué)原理，格言等，從句仍然要用一般現(xiàn)在時(shí)。例如：Eg: He said （that the earth moves round the sun. / that light travels much faster than sound.）The teacher told us （seeing is believing.）3.語(yǔ)序：陳述語(yǔ)序，主+謂+其他* when will yo

7、u leave for Beijing?（Could you please tell me） Could you please tell me when you will leave for Beijing?*Has she seen the movie？（He asked.） He asked if she had seen the movie.*Could you tell me what's the matterwrong with you?賓語(yǔ)從句是英語(yǔ)復(fù)合句中的其中非常重要的從句之一。它是用一個(gè)句子做另一個(gè)句子的賓語(yǔ)，將這個(gè)句子叫做賓語(yǔ)從句。賓語(yǔ)從句做介詞或及物動(dòng)詞的賓語(yǔ)。現(xiàn)

8、在從下列三個(gè)方面總結(jié)歸納如下：一，引導(dǎo)詞  A,由that 引導(dǎo)的陳述句性的賓語(yǔ)從句，在很多動(dòng)詞如say, think, wish , hope, see, believe, agree, expect, hear , feel等動(dòng)詞后。連詞that只起連接作用，在從句中不做句子的成分，也無(wú)詞匯意義，在口語(yǔ)中常被省略，但在大多數(shù)情況下還是以不省為好，特別是在筆語(yǔ)中。  例：I told him that he was wrong.  l在think,believe, suppose, expect等動(dòng)詞引起的賓語(yǔ)從句中，有時(shí)謂語(yǔ)盡管是

9、否定意義，卻不用否定形式，而將think 等動(dòng)詞變?yōu)榉穸ㄐ问健?#160; 例：I dont think you are right. (我認(rèn)為你做的不對(duì))  l在許多帶有復(fù)合賓語(yǔ)的句子中，that引導(dǎo)的賓語(yǔ)從句經(jīng)常移到句子的后面，而用it做形式賓語(yǔ)。  例：We think it wrong that he told a lie to everyone (我認(rèn)為他向每一個(gè)人撒謊是錯(cuò)誤的)  B,由連詞if、 whether 引導(dǎo)的表示“是否”的賓語(yǔ)從句。Whether,if 在從句中不做句子的成分，一般情況下，whethe

10、r和if 可以替換。  例：I dont know if/whether he will come tomorrow.  The teacher asked if/whether we had finished the experiment.  l在介詞后面的賓語(yǔ)從句中不用if引導(dǎo)  例：Everything depends on whether we have enough money。  l賓語(yǔ)從句中有or not時(shí)不用if引導(dǎo).  例：I dont know wheth

11、er the movie star will come or not.  l和不定式連用作賓語(yǔ)時(shí)不用if引導(dǎo).  例：Whether to go there or not hasnt been decided.  二，賓語(yǔ)從句的語(yǔ)序，  賓語(yǔ)從句從句的語(yǔ)序必須是陳述語(yǔ)序，既連接詞+主語(yǔ)+謂語(yǔ)+其他成分  例：I believe that they will come soon.  He asked me whether I was a teacher.  

12、They wanted to know what they can do for us.三，賓語(yǔ)從句的時(shí)態(tài)。  賓語(yǔ)從句的時(shí)態(tài)受主句的限制，  既：主句是一般現(xiàn)在時(shí)態(tài)，從句根據(jù)實(shí)際情況而定。  主句是一般過(guò)去時(shí)態(tài)，從句用相應(yīng)的過(guò)去的時(shí)態(tài)。如果從句的動(dòng)作發(fā)生在主句之前，則從句要用過(guò)去完成時(shí)態(tài)。  例:  1)She says that she is a student.  She said that she was a student.  2)She say

13、s that she will fly to Japan in a week.  She said that she would fly to Japan in a week.  3)She says that she has finished her homework already.  She said that she had finished her homework already.  4)She says that she can sing a song in English.  S

14、he said that she could sing a song in English.  l如果賓語(yǔ)從句說(shuō)的是客觀(guān)真理、自然現(xiàn)象或事實(shí)時(shí)，這時(shí)賓語(yǔ)從句要用一般現(xiàn)在時(shí)態(tài)。  例：The teacher said that the earth goes round the sun.  He told me that Japan is an island country.  lCould you tell me是用來(lái)征詢(xún)對(duì)方的意見(jiàn)，語(yǔ)氣委婉，并不表示過(guò)去。  例：Could you tell m

15、e when we will visit the Histury Museum?  注意事項(xiàng)：  由陳述句變成賓語(yǔ)從句時(shí)，要注意人稱(chēng)的變化。  例：She said: “I have been to England before.”  She said that she had been to England before.  She asked me: “Do you like maths?”  She asked me if I liked maths. 

16、60; 賓語(yǔ)從句與簡(jiǎn)單句的交換。  由連接代詞和連接副詞引導(dǎo)的賓語(yǔ)從句，如果賓語(yǔ)從句的主語(yǔ)和主句的主語(yǔ)是同一個(gè)人時(shí)，可以用“疑問(wèn)詞+不定式”做賓語(yǔ)的簡(jiǎn)單句結(jié)構(gòu)。  例：I dont know what I should do next. 賓語(yǔ)從句專(zhuān)項(xiàng)習(xí)題鞏固練習(xí)1.Have you decided _for Australia?A. when will you leave B. when do you leaveC. you will leave when D. when you will leave2.Can you tell me _ ?A. whe
