1、賓語 從句,一、概 述 在句子中起賓語作用的從句稱為賓語從句。賓語從句一般由下面一些詞引導(dǎo)。 1.that引導(dǎo) 2.whether/if引導(dǎo) 3.連接代詞who whom whose what which 4. 連接副詞when why where how。,1that屬于從屬連接詞，在賓語從句中沒有實際意義，只是起引導(dǎo)從語的作用。,1）作動詞的賓語從句 We all know (that) success calls for hard work. 我們都知道成功需要付出艱辛的勞動。 We knew (that) he had made a mistake. 我們知道他犯了一個錯誤。 2）在某

2、些be+形容詞的結(jié)構(gòu)后面也可以跟that引導(dǎo)的賓語從句。 如sure, certain, glad, pleased, happy, afraid, surprised, sorry等。 I am sure that I have posted the letter. 我的確把那封信寄了。 I am afraid that you are right. 恐怕你是對的。,【要點(diǎn)拓展】 一般說來引導(dǎo)賓語從句的that可以省略。如果有多個that引導(dǎo)的賓語從句，第一個that可以省略，其他一般不省略。 I know (that) you are right. 我知道你是對的。 The doctor

3、told me (that) I should take more water and that things would get better very soon醫(yī)生告訴我要多喝水，情況很快就會好轉(zhuǎn)。,2whether /if在做“是否”解時引導(dǎo)賓語從句，常放在動詞know，ask，care，wonder，find out等之后。在口語中常用if。 whether /if在賓語從句中不作任何成分，但含有“是否”的含義，在句子中不可省略。 I dont know whether/ if this bike is hers. 我不知道這輛自行車是否是她的。 Can you tell me whe

4、ther/ if your father joined the Party in 1990? 你能告訴我你父親是不是1990年入黨的？,【要點(diǎn)拓展】,whether/if在表示“是否”，引導(dǎo)賓語從句時常可通用。但一下情況只可以用whether。 介詞后的賓語從句用whether引導(dǎo)。 We are talk about whether we can get the chance. 我們再討論我們是否可以得到這個機(jī)會。 whether引導(dǎo)賓語從句可以與or not連用 He doesnt know whether they will plant trees on Saturday or not.

5、 他不知道他們周六是否會去植樹。 Whether引導(dǎo)的賓語從句可以置于句首。 Whether they will join in the picnic I dont care. 他們是否參加野餐，我不在乎。 在不定式前只用whether。 Im just wondering whether to stay for another hour. 我不知道是否要再等一個小時。,3由連接代詞引導(dǎo)的賓語從句 who whom whose what which Do you know whose child he is? 你知道他是誰的孩子嗎？ Do you remember what you s

6、hould do next? 你記得你接下來應(yīng)該做什么嗎？ I want to know which medicine he has taken. 我要知道他服了哪種藥。 Please tell me who called me just now. 請告訴我剛才誰打電話給我。 I dont know whom they are speaking to. 我不知道他的在跟誰講話。,【要點(diǎn)拓展】,連接代詞一般指疑問，但what除了指疑問之外，也可指陳述。 I dont believe what you said. 我不相信你所說的話。,4、由連接副詞引導(dǎo)的賓語從句when why where ho

7、w,He asked me where they were born. 他問我他們出生在哪里。 He asks how we can help protect the environment. 他問我們怎樣才能為保護(hù)環(huán)境出點(diǎn)力。 I cant find out why the machine doesnt work well. 我不能找出這臺機(jī)器為什么動轉(zhuǎn)不靈。 Did you ask the teacher when we would have a test? 你問老師我們什么時候進(jìn)行測驗了嗎？,【要點(diǎn)拓展】,連接副詞引導(dǎo)的賓語從句一般表示疑問，但有時也表示陳述。連接副詞在從句中做狀語。

8、 I remember when I lived with my grandparents in the country.（when在從句中作時間狀語，不表示疑問。） 我記得我和爺爺奶奶在鄉(xiāng)村住過的日子。,【注意】,1、由連接代詞、連接副詞引導(dǎo)的賓語從句可以向“疑問詞+不定式”結(jié)構(gòu)轉(zhuǎn)化。 I dont know how I should do with the gifts. =I dont know how to do with the gifts. 我不知道怎么處理禮物。,1.賓語從句的語序在賓語從句中需要運(yùn)用陳述句語序。 He asked me where they were born.

9、 他問我他們出生在哪里。 Do you remember what you should do next? 你記得你接下來應(yīng)該做什么嗎？,賓語從句高頻考點(diǎn),2時態(tài)的呼應(yīng)賓語從句中的謂語動詞的時態(tài)常受到主句中謂語動詞時態(tài)的影響。因此，要注意保持主句和從句間時態(tài)的一致。,例如： He says that Lily is(will be/ was) a doctor. 他說莉莉是（將要成為/過去是）醫(yī)生。 Ill tell you what I am doing (did/shall do). 我將要告訴你我正在做（過去做/將要做）什么。,（1）當(dāng)主句是現(xiàn)在的某種時態(tài)，從句可用所需要的任何時態(tài)。,（

10、2）如果主句是過去的某種時態(tài)，賓語從句的時態(tài)就比較復(fù)雜。,1）從句用一般過去時或過去進(jìn)行時表示與主句謂語動作同時發(fā)生。例如： I thought he was old. 我認(rèn)為他老了。 He wanted to know who she was waiting for. 他想知道她在等誰。 2）從句的謂語動詞表示在主句動作之前完成的動作，則用過去完成時。 He said that he had finished reading the book. 他說他看完了這本書。,3）從句謂語動詞表示在主句動作之后發(fā)生的動作，則用過去將來時。 She said that she was going

11、to buy a new bike next week. 她說她下個星期要去買一輛新自行車。 I wasnt sure if it would rain. 我沒有把握確定天是否會下雨。,4）從句表示普通真理時，其謂語動詞用一般現(xiàn)在時。 例如： The teacher told us the moon travels round the earth. 老師告訴我們，月亮繞地球轉(zhuǎn)。,3.從句中的否定轉(zhuǎn)移主句謂語動詞是think, believe, expect, guess等，表示“認(rèn)為，相信，期望，猜想“等意思，主句的主語是第一人稱，且時態(tài)為一般現(xiàn)在時時，從句的否定一般要轉(zhuǎn)移到主句上。其反意疑問

12、句一般與賓語從句一致。 I dont believe she will take part in the English evening.我相信她不會參加英語晚會。 I dont think its your fault. 我認(rèn)為這不是你的錯。 改為反意疑問句 I dont think its your fault, is it?,4 混合賓語從句 當(dāng)賓語從句的引導(dǎo)詞是who，which，what，when，where，how，why等時，不按正常語序安排，講這類引導(dǎo)詞置于句首。這時主句中的謂語動詞常是think, believe, expect, guess Who do you think

13、 Tom will invite to the party? 你認(rèn)為湯姆會邀請誰來參加聚會?,賓語從句應(yīng)掌握的要點(diǎn),1在四種類型的賓語從句中必須用陳述句的語序，即主語+謂語動詞+其它成分，句末用句號；但主句為疑問句時，句末用問號。 2在帶有賓語從句的復(fù)合句中，要注意主句和從句的時態(tài)的呼應(yīng)。 當(dāng)主句的謂語動詞是現(xiàn)在時態(tài)時，從句的謂語動詞可用任何需要的時態(tài)。 當(dāng)主句的謂語動詞是過去時態(tài)時，從句的謂語動詞只能用過去時態(tài)范圍內(nèi)的某一種形式。 從句表示普遍真理時，即使主句的謂語動詞是過去時，從句的謂語動詞也須用一般現(xiàn)在時。 3. 在think, believe等動詞引起的賓語從句中，如果否定的是后面的從

14、句，一般要將主句動詞改為否定形式，而從句仍然用肯定式。,1. What did Mike say? He said ____________________. A. if you are free the next week B. what colour was it C. the weather is fine D. summer comes after spring 2. Let me tell you __________________. A. how much is the car B. how much does the car cost C
