2、.賓語(yǔ)從句的時(shí)態(tài)變化2.if和wether的區(qū)別3. when與if的用法The teaching process(教學(xué)過(guò)程)Step 1.Lead-in復(fù)習(xí)書(shū)上的內(nèi)容導(dǎo)入新課（P9）, (叫學(xué)生劃分這些句子的成分,引出該堂課的教學(xué)內(nèi)容賓語(yǔ)從句)Step 2. Presentaion一. 概念：置于動(dòng)詞、介詞等詞性后面起賓語(yǔ)作用的從句叫賓語(yǔ)從句。如：,He said he was good at drawing. (動(dòng)詞賓語(yǔ))He began to think about what he should do. 他開(kāi)始考慮應(yīng)當(dāng)怎樣做。(介詞賓語(yǔ))。6 / 6（此外，除了謂語(yǔ)動(dòng)詞、介詞能帶賓語(yǔ)從句

3、外，動(dòng)詞不定式，動(dòng)名詞形式后面也能帶賓語(yǔ)從句，還有些形容詞（afraid,sure,glad等）之后也可以帶賓語(yǔ)從句。）二.結(jié)構(gòu)：主語(yǔ)+謂語(yǔ)+連接詞+賓語(yǔ)從句三.種類：根據(jù)引詞不同，賓語(yǔ)從句可分為三類。1.由that引導(dǎo)的賓語(yǔ)從句。如果賓語(yǔ)從句是由陳述句充當(dāng)，用that引導(dǎo)，that無(wú)詞義，在口語(yǔ)或非正式文體中常省略。如：The teacher said (that) he is a good student .The teacher said (that )the earth goes round the sun。The teacher said (that) light travels m

4、uch faster than sound. (舉此例是為下面講時(shí)態(tài)作鋪墊)2.由if或whether引導(dǎo)的當(dāng)賓語(yǔ)從句。如果賓語(yǔ)從句是由一般疑問(wèn)句充當(dāng)，就用if或whether引導(dǎo)，意為“是否”。如：I don't know if whether it will rain today。在賓語(yǔ)從句中，if和whether通常可以互換，但在下列情況下只能用whether：在具有選擇意義，尤其是直接與or not連用時(shí)，往往用whether（ifor not也可以使用）。如：I don't know whether or not it will rain today。(=I

5、 don't know if it will rain or not today。在介詞之后用whether。如：Im thingking about whether it will rain today.若用if會(huì)引起歧義時(shí)，則用whether。如：Please let me know if it will rain today.可理解為：aPlease let me know whether it will rain today.請(qǐng)告訴我今天會(huì)不會(huì)下雨。bIf it will rain today.，please let me know如果今天會(huì)下雨，請(qǐng)告訴我。whether置于句

6、首時(shí)，不能換用if。如：Whether it will rain or not today，Ican't say今天會(huì)不會(huì)下雨，我說(shuō)不上來(lái)。引導(dǎo)主語(yǔ)從句和表語(yǔ)從句時(shí)宜用whether。如：Whether it will rain or not today is still a question今天會(huì)不會(huì)下雨還是個(gè)問(wèn)題。The question is whether it will rain or not today問(wèn)題是今天會(huì)不會(huì)下雨。在不定式前用whether。如：I havent decided whether to go to Beijing in National Day.(=

7、 I havent decided to whether/if I would go to Beijing in National Day.3.由特殊疑問(wèn)詞引導(dǎo)的賓語(yǔ)從句。如果賓語(yǔ)從句是特殊疑問(wèn)句，只需用原來(lái)的特殊疑問(wèn)詞引導(dǎo)。如：I want to know how you studied English before.I want to know why he didnt come yesterday.I want to know where he will go tomorrow.I want to know what you are doing now.I want to know wh

8、at you were doing this time yesterday.I want to know when you go to school in the morning.She wanted to know how you studied English before.She wanted to know why he didnt come yesterday.She wanted to know where he would go tomorrow.She wanted to know what you were doing then.She wanted to know what

9、 you were doing this time yesterday.She wanted to know when you go to school in the morning.She wanted to know what your names are.注意：if和when既可以引導(dǎo)賓語(yǔ)從句，也可以引導(dǎo)狀語(yǔ)從句，應(yīng)注意它們?cè)趦煞N從句中的意思和用法的不同。if和when引導(dǎo)賓語(yǔ)從句時(shí)，分別意為“是否”和“何時(shí)”，其時(shí)態(tài)應(yīng)和主句時(shí)態(tài)相呼應(yīng)；它們引導(dǎo)狀語(yǔ)從句時(shí)，意思分別為“如果，假如”和“當(dāng)時(shí)候”，當(dāng)主句時(shí)態(tài)是一般將來(lái)時(shí)時(shí)，其時(shí)態(tài)用一般現(xiàn)在時(shí)。因此，遇到它們就要認(rèn)真分析一下，它們究竟是引導(dǎo)什

10、么從句。如：If it rains tomorrow, I wont come.（時(shí)間狀語(yǔ)從句）I dont know if it will rain tomorrow. （賓語(yǔ)從句）I want to know when you go to school in the morning. （賓語(yǔ)從句）When you go to school,please tell me. （時(shí)間狀語(yǔ)從句）4.歸納總結(jié)：當(dāng)賓語(yǔ)從句是由陳述句充時(shí)，用that引導(dǎo)；當(dāng)賓語(yǔ)從句是由一般疑問(wèn)句充當(dāng)時(shí)，用if或whether引導(dǎo)；如果賓語(yǔ)從句是特殊疑問(wèn)句，只需用原來(lái)的特殊疑問(wèn)詞引導(dǎo)。四. 時(shí)態(tài)（一致性原則）引導(dǎo)學(xué)生從所

11、舉例子當(dāng)中歸納總結(jié)得出：含賓語(yǔ)從句的復(fù)合句，主、從句謂語(yǔ)動(dòng)詞的時(shí)態(tài)呼應(yīng)應(yīng)包括以下三點(diǎn)內(nèi)容：1）如果主句的謂語(yǔ)動(dòng)詞是一般現(xiàn)在時(shí)，從句的謂語(yǔ)動(dòng)詞可根據(jù)需要，選用相應(yīng)的任何時(shí)態(tài)。2）如果主句的謂語(yǔ)動(dòng)詞是過(guò)去時(shí)，賓語(yǔ)從句的謂語(yǔ)動(dòng)詞要根據(jù)需要，選用過(guò)去（即一般過(guò)去時(shí)、過(guò)去進(jìn)行時(shí)、過(guò)去將來(lái)時(shí)或過(guò)去完成時(shí)）的某一種形式。(詳見(jiàn)下表) 主句時(shí)態(tài)  從句時(shí)態(tài)  連接前 連接后  一般現(xiàn)在時(shí) 時(shí)態(tài)保持不變 一般過(guò)去時(shí)  一般現(xiàn)在時(shí)  一般過(guò)去時(shí)  一般過(guò)去時(shí)  一般過(guò)去時(shí)  

12、一般將來(lái)時(shí)  過(guò)去將來(lái)時(shí)  現(xiàn)在進(jìn)行時(shí)  過(guò)去進(jìn)行時(shí) 現(xiàn)在完成時(shí)  過(guò)去完成時(shí)3）如果賓語(yǔ)從句所表示的是客觀事實(shí)、普遍真理、自然現(xiàn)象或習(xí)慣性動(dòng)作等，不管主句用什么時(shí)態(tài)，從句時(shí)態(tài)都用一般現(xiàn)在時(shí)。如：五.語(yǔ)序：陳述句語(yǔ)序。(引導(dǎo)學(xué)生從例子中歸納總結(jié)得出)六. 賓語(yǔ)從句的否定轉(zhuǎn)移。當(dāng)主句的謂語(yǔ)動(dòng)詞為 think, guess, suppose, believe等，且主語(yǔ)為第一人稱時(shí)，從句若表示否定，一般將否定詞not轉(zhuǎn)移到主句的謂語(yǔ)中，這就叫作“否定轉(zhuǎn)移”。如：“我認(rèn)為他不是一個(gè)好學(xué)生”這句話不能說(shuō)成I think （that） he is

13、 not a good student.而是要說(shuō)成I don't think （that） he is a good student.但是如果動(dòng)詞為非一般現(xiàn)在時(shí)或主語(yǔ)不是第一人稱時(shí)，否定不轉(zhuǎn)移。如：She thinks（that）he is not a good student.I thought ( that) he is not a good student. 七從句的簡(jiǎn)化1. 當(dāng)主句謂語(yǔ)動(dòng)詞是find，see，watch，hear等感官動(dòng)詞時(shí)，從句常簡(jiǎn)化為“賓語(yǔ)賓補(bǔ)”結(jié)構(gòu)，賓補(bǔ)為不帶to的不定式或V-ing形式。如：She found that the wallet w

14、as lying on the ground.She found the wallet lying on the ground.2. 當(dāng)主句謂語(yǔ)動(dòng)詞是hope，wish，decide，forget，plan，agree等，且主句主語(yǔ)與從句主語(yǔ)相同時(shí)，從句可簡(jiǎn)化為不定式結(jié)構(gòu)。如：She agreed that she could help me with my maths. She agreed to help me with my maths.3. 在連接代詞/副詞引導(dǎo)的賓語(yǔ)從句中，當(dāng)從句主語(yǔ)與主句主語(yǔ)或間接賓語(yǔ)一致時(shí)，賓語(yǔ)從句可簡(jiǎn)化為“連接代詞/副詞不定式”結(jié)構(gòu)。如：Can you tell

15、 me how I can get to the station? Can you tell me how to get to the station?  八.人稱的變化和標(biāo)點(diǎn)的使用(八年級(jí)學(xué)直接引語(yǔ)轉(zhuǎn)化成間接引語(yǔ)時(shí)講過(guò)，這里不重點(diǎn)講，只作簡(jiǎn)單的復(fù)習(xí))1. 從句的主語(yǔ)如果是第一人稱，變?yōu)橘e語(yǔ)從句則與主句的主語(yǔ)一致；如果是第二人稱，則與主句的賓語(yǔ)一致；如果是第三人稱，不用變化。如： “May I use your knife?” He asked me. He asked me if he might use my knife. “Do you know her teleph

16、one number?” He asked me.He asked me if I know her telephone number.2. 賓語(yǔ)從句的標(biāo)點(diǎn)均由主句決定。主句是陳述句，用句號(hào)；主句是疑問(wèn)句，用問(wèn)號(hào)。如：Who will give us a talk? I dont know. I dont know who will give us a talk.Do you know? Where does he live? Do you know where he lives? Step 3、Practice【中考范例】1. Miss Green didnt tell us _

17、in 2002.  A. where does she live       B. Where she lives  C. where did she live        D. where she lived   （北京市中考試題）【解析】答案：D。該題考查的是賓語(yǔ)從句的語(yǔ)序和時(shí)態(tài)。賓語(yǔ)從句應(yīng)用陳述句的語(yǔ)序和時(shí)態(tài)，所以應(yīng)選D。2. Would you please tell me _?  （上海市徐匯區(qū)中考試題）

18、  A. when did he come home   B. where he would play football  C. if he had seen the film     D. why he didnt watch the game【解析】答案：D。該題考查的是賓語(yǔ)從句的語(yǔ)序和時(shí)態(tài)。主句用的實(shí)際上是現(xiàn)在時(shí)，賓語(yǔ)從句在這個(gè)句子里應(yīng)用陳述句的語(yǔ)序和一般過(guò)去時(shí)。3. I dont know when _.  A. will the train leave         B. the tra
