宾语从句学习宾语从句要抓住三要素:连接词、语序和时态。
1.宾语从句的定义宾语从句在复合句中起宾语的作用,可以作动词的宾语,也可以做介词的宾语作动词的宾语:I heard that he would come here later on.主语谓语动词一个句子作宾语作介词的宾语:He said nothing about who broke the window last night.主语谓语动词代词作动词的宾语介词一个句子作介词的宾语2.宾语从句中引导词(连接词)的用法在复合句中作主句的宾语,引导词有:连词:that (that 常可省略),whether, if代词:who, whose, what ,which副词:when ,where, how, why 等。
①连词:He told me (that he would) go to the college the next year 他告诉我他明年上大学.I don’t know if there will be a bus any more. 我不知道是否还会有公交车.Nobody knew whether he could pass the exam. 没有人知道他是否会通过考试.that引导的宾语从句(在非正式场合that可以省略)可跟that从句做宾语的动词有:say, think, 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。
The boy believes that he will travel through space to other planets.Attention:宾语从句的否定转移当主句谓语动词是 think, believe, suppose, expect 等词,而宾语从句的意思是否定时,常把否定转移至主句表示。

1.语序无论主句是陈述句还是疑问句,宾语从句都必须使用陈述语序,即“主句+连词+宾语从句(主语+谓语+??)”句式。
根据连接词在从句中所担任的不同成分,可分为以下四种:1)连接词+谓语。
连接词在从句中作主语。
常见的连接词有: who,what,which等。
如: Could you tell me who knows the answer,please?你能告诉我谁知道答案吗?The small children don't know what is in their stockings.这些小孩子不知道袜子里有什么东西? 2)连接词+名词+谓语。
连接词在从句中作主语的定语。
常见的连接词有:whose,what,which,how many,how much等。
如:He asked whose handwriting was the best in our class.他问我们班上谁的书法最好。
The teacher asked us how many people there were in the room.老师问我们房间里有多少人。
3)连接词+主语+谓语。
连接词在从句中作宾语、状语或表语。
常见的连接词有:who(m),what,which,how many,how much,when,why,how,where,if /whether(在句中不充当任何成分)等。
如:He hasn't decided if he'll go on a trip to Wuxi.他还没决定是否去无锡旅行。
Could you tell me what I should do with the money ?你能告诉我我如何处理这笔钱吗?4)连接词+名词+主语+谓语。
直接引语变间接引语(宾语从句)讲解与练习一.讲解:在复合句中,作宾语的句子(主谓结构)就叫宾语从句。
直接引语变间接引语多数情况下构成宾语从句。
变化时应注意以下几点:1.引导词(连词)①如果直接引语是陈述句,变成间接引语,引导词用that, that没有实际意义,口语或非正式文体中常省略e.g He said, “My mother is a doctor.”→He said (that) his mother was adoctor.②如果直接引语是一般疑问句,变成间接引语,引导词就用if。
不能省略 e.g “Are youEnglish?” He asked m e→He asked me if I was English.③如果直接引语是特殊疑问句,变成间接引语,引导词就用特殊疑问句的疑问词,如:whatwhen where which who how等,这些词有意义,不能省略:eg “How old are you ?” He askedm e→He asked me how old I was.二.间接引语的宾语从句中,引导词之后都必须使用陈述语序,即“引导词+主语+谓语…),肯定式的宾语从句不用助动词do(did或does) e.g.She asked, “What does he want?”→She asked what he wanted.He asked me ,“Do you like English?”→He asked me if I liked English.三.时态的变化:1.如果主句中的谓语动词用一般过去时,则间接引语中宾语从句须用过去的某种时态。
基本原则是:往过去的方向推一个时态,即一般现在时变成一般过去时,现在进行时变成过去进行时,一般将来时变成过去将来时eg:① He asked me, “Do you have a dictionary?”→He asked me if I had a dictionary.② She asked, “What is Tom doing? →She asked what Tom was doing.③ She said ,“I will leave a message on his desk.”→She said that she would leavea message on his desk.2.如果宾语从句表达的是客观真理,自然现象。
宾语从句一、学习目标:学习并掌握宾语从句的定义和应用二、重难点:宾语从句引导词的选择在复合句中用作宾语的从句叫做宾语从句。
它是众多从句中的一员,在复合句中作主句谓语动词、介词或某些形容词的宾语。
在及物动词的后面可以接一个名词来充当宾语,如:I know the man.而这时也可以用一个句子来充当宾语,如:I know that the man is a policeman.主句引导词从句宾语从句三大块: 1. 引导宾语从句的连词和代词选择; 2. 宾语从句的语序; 3. 宾语从句的时态。
Ⅰ.宾语从句的引导词1.陈述句充当宾语从句时,用that引导,that无词义,在口语或非正式文体中常省略。
如:My teacher said I was a good boy.老师说我是个好男孩。
She doesn’t know (that) she is seriously ill. I am sure (that) he will succeed.用以下开头与下列句子连成宾语从句:1. I know …2. She says …3. Tell your friend …(that)1.This is a book.2.You like singing.2.当由一般疑问句充当宾语从句时,用if或whether引导,意为“是否”。
如:(1) Is Jim a good student? I don’t knowI don’t know if /whether Jim is a good student.(2) Does Kate get up early? Do you know?Do you know if /whether Kate gets up early?用以下开头与下列句子连成宾语从句: 1.Do you know …2.I want to know …3.The teacher asks …if/whether1.Is he reading ?2.Do you get up at six?3.Does Tom work hard?※注意:只能用whether不用if 的三种情况•一般情况下,if 和whether可以互换,但以下3种情况只能用whether:•①与or not连用:He asked me whether or not I was coming. Let me know whether you can come or not.•②在介词之后:It depends on whether it is going to rain. I worry about whether I hurt her feelings •③在不定式之前:We haven’t decided whether to go there. I don’t know whether to accept or refuse.3.如果宾语从句原来是特殊疑问句,只需用原来的疑问词引导。

宾语从句讲与练在复合句中用作宾语的从句叫宾语从句。
1.语序无论主句是陈述句还是疑问句,宾语从句都必须使用陈述语序,即“主句+连词+宾语从句(主语+谓语+……)”句式。
根据连接词在从句中所担任的不同成分,可分为以下四种:1)连接词+谓语。
连接词在从句中作主语。
常见的连接词有:who,what,which等。
如:Could you tell me who knows the answer,please?你能告诉我谁知道答案吗?The small children don't know what is in their stockings.这些小孩子不知道袜子里有什么东西?2)连接词+名词+谓语。
连接词在从句中作主语的定语。
常见的连接词有:whose,what,which,how many,how much等。
如:He asked whose handwriting was the best in our class.他问我们班上谁的书法最好。
The teacher asked us how many people there were in the room.老师问我们房间里有多少人。
3)连接词+主语+谓语。
连接词在从句中作宾语、状语或表语。
常见的连接词有:who(m),what,which,how many,how much,when,why,how,where,if /whether(在句中不充当任何成分)等。
如:He hasn't decided if he'll go on a trip to Wuxi.他还没决定是否去无锡旅行。
Could you tell me what I should do with the money ?你能告诉我我如何处理这笔钱吗?4)连接词+名词+主语+谓语。
连接词在从句中作宾语或表语的定语。
常见的连接词有:what,which,how many,how much,how等。
如:Do you know which class he is in ?你知道他在哪个班吗?She asked me if I knew whose pen it was.她问我是否知道这是谁的钢笔。
2.连接词1)当由陈述句充当宾语从句时,用that引导,that无词义,在口语或非正式文体中常省略。
如:He said that he could finish his work before supper.他说他会在晚饭前完成工作。
2)当由一般疑问句充当宾语从句时,用if或whether引导,意为“是否”。
如:I don't know if /whether he still lives here after so many years.我不知道这么多年后他是否还住在这儿。
但在下列情况下只能用whether:①在具有选择意义,又有or或or not时,尤其是直接与or not连用时,往往用whether(if…or not也可以使用)。
如:Let me know whether /if he will come or not.(=Let me know whether or not he will come)让我知道他是否能来。
I don't know whether /if he does any washing or not.(=I don't know whether or not he does any washing.)我不知道他洗不洗衣服。
I wonder whether we stay or whether wego.我不知道我们是去还是留。
②在介词之后用whether。
如:I'm interested in whether he likes English.我关心的是他是否喜欢英语。
We're thinking about whether we can finish the work on time.我们正在考虑是否能按时完成这项工作。
I worry about whether I hurt her feelings.我担心是否伤了她的感情。
③在不定式前用whether。
如:He hasn't decided whether to visit the old man.他尚未决定是否拜访那位老人。
I don't know whether to go.我不知去否。
He hasn't decided whether to go by bus or by train.他还未决定是乘公共汽车去还是坐火车去。
④whether置于句首时,不能换用if。
如:Whether this is true or not,I can't say.这是否真的我说不上来。
⑤引导主语从句和表语从句时宜用whether。
如:Whether she will come or not is still a question.她是否能来还是个问题。
The question is whether we can catch the bus.问题是我们能否赶上公共汽车。
⑥若用if会引起歧义时,则用whether。
如:Please let me know if you like the book.可理解为:a.Please let me know whether you like the book.请告诉我你是否喜欢这本书。
b.If you like the book,please let me know.你如果喜欢这本书,请告诉我。
3)如果宾语从句原来是特殊疑问句,只需用原来的特殊疑问词引导。
如:Could you tell me why you were late for the meeting this morning?你能告诉我今天早上你为什么开会迟到吗?3.时态含宾语从句的复合句,主、从句谓语动词的时态呼应应包括以下三点内容:1)如果主句的谓语动词是一般现在时,从句的谓语动词可根据需要,选用相应的任何时态。
如:I don't know when he will come back.我不知道他将何时回来。
He tells me that his sister came back yesterday.他告诉我他姐姐昨天回来了。
2)如果主句的谓语动词是过去时,宾语从句的谓语动词只可根据需要,选用过去时态即一般过去时、过去进行时、过去将来时或过去完成时的某一种形式。
如:①The children didn't know who he was.孩子们不知道他是谁。
②He asked his father how it happened.他问他父亲这件事是如何发生的。
3)如果宾语从句所表示的是客观事实、普遍真理、自然现象或习惯性动作等,不管主句用什么时态,从句时态都用一般现在时。
如:The teacher said that the earth goes round the sun.老师说地球绕着太阳转。
4.注意:if和when既可以引导宾语从句,也可以引导状语从句,应注意它们在两种从句中的意思和用法的不同。
if 和when引导宾语从句时,分别意为“是否”和“何时”,其时态应和主句时态相呼应;它们引导状语从句时,意思分别为“如果,假如”和“当……时候”,当主句时态是一般将来时时,其时态用一般现在时。
它们常常放在含有状语从句和宾语从句的题干中进行综合考查。
如:—Do you know when he will come back tomorrow ?你知道他明天什么时候回来吗?—Sorry,I don't know.When he comes back,I'll tell you.对不起,不知道。
当他回来了,我将告诉你。
—I don't know if he will come.我不知道他是否会来。
—He will come if it doesn't rain.如果不下雨,他会来的。
简化宾语从句常用六法同学们常会遇到把含有宾语从句的复合句转化为简单句,使其与原句意思相同(或相近)的试题。
下面就介绍几种常用的简化宾语从句的方法:方法一:当主句谓语动词是hope,decide,wish,choose,agree,promise等,且宾语从句的主语与主句主语一致时,宾语从句可简化为不定式结构。
例如:Li Ming hopes he will be back very soon. →Li Ming hopes to be back very soon.We decided that we would help him. →We decided to help him.方法二:当主句谓语动词是know,learn,remember,forget,tell等动词,且主句主语与从句主语一致时,宾语从句可简化为“疑问词+不定式”结构。
例如:She has forgotten how she can open the window. →She has forgotten how to open the window.注:当主句谓语动词是tell,ask,show,teach等动词,且后带双宾语,从句主语和间接宾语一致时,宾语从句可简化为“疑问词+不定式”结构。
例如:Could you tell me how I can get to the station?→Could you tell me how to get to the station?方法三:当主句的谓语动词是order(命令),require(需要)等时,如果主句和从句的主语不一致,宾语从句可简化为“名词(代词)+不定式”结构。
例如:The headmaster ordered that we should start at once. →The headmaster ordered us to start at once.方法四:某些动词后的宾语从句,可以用介词加动名词(短语)等其他形式简化。
例如:He insisted that he should go with us. →He insisted on going with us.The poor boy doesn’t know when and where he was born. →The poor boy doesn’t know the time and the place of his birth.方法五:某些动词后面的宾语从句可转化为“宾语+V-ing形式(作宾语补足语)”结构。
