whether,if及疑问词引导的宾语从句

that引导的宾语从句宾语从句是一种名词性从句，在句中作及物动词的宾语，或介词的宾语，或形容词的宾语。

根据引导宾语从句的不同连词，宾语从句可分为三类。

（1）that引导的宾语从句（2）whether / if引导的宾语从句（3）疑问词引导的宾语从句一、由that引导的宾语从句：that只有语法作用，没有实在的意义，在口语和非正式文体中可以省略。

例如：He said (that) he wanted to stay at home.他说他想呆在家里。

She doesn’t know (th at) she is seriously ill.她不知道她病得很严重。

I am sure (that) he will succeed.我确信他会成功。

小试牛刀：1、She said. You looked great！2、She said. I went to Beijing and visited the Great Wall.注意：（一）并非所有的动词后面都可以接that引导的宾语从句，只有当谓语动词表示肯定概念时，如believe, expect，explain, feel, hear, hope, imagine, prefer,promise, report, say, see, tell, think,understand, warn, wish等其后面的句子一般由that引导。

此时，that没有任何实际意义，目的是使读者清楚后面的句子是作前面动词的宾语，多数情况下可以省略。

（二）不能省略that的2种情况：1、当that作介词except, in 宾语时例如：They believe in that she must still be single.I know nothing about him except that he is living in Beijing.（2）用it做形式宾语的宾语从句时（it常可以放在动词think, find, consider, believe, feel, make等后作为形式宾语，而真正的宾语——that从句则放在句尾）例如：We heard it that she would get married next month.课堂练习：( )1、Don’t lose your heart. I believe in you can finish the work by yourself.A. \B. thatC. whichD. if( )2、I think we can be good friends.A. thatB. whatC. whichD. if( )3、She said he would go to the hospital.A. \B. whatC. whichD. if( )4、－Have you ever seen the movie 2012?－Yes, but I don’t believe ____ the year 2012 will see the end of the world. 【2012 菏泽】A. thatB. whatC. howD. if二、特殊的宾语从句———间接引语用自己话转述别人的话，叫做间接引语。

宾语从句一、定义：当一个句子充当宾语时，我们就把这个句子叫宾语从句，含有从句的句子叫主句，主句和从句之间有连接代词或连接副词。

二、宾语从句的三类引导词1.由that引导的宾语从句陈述句作宾语，由that引导，that 在句中没有词义，也不做任何句子成分，并且在口语中常常省略。

如：I think (that) he is very old.He says (that ) he will come back tomorrow.He said (that) he wanted to see the teacher.2.由if或whether引导的宾语从句由if/whether连接一般疑问句句式，要特别注意把语序改为陈述句语序。

if/whether在句中具有词义“是否”，不能省略。

在口语中常用if,wether常与or not连用。

如：He asked if/wether they needed more tea.I don’t know wether he will pass the exam or not.注意：当主句动词跟宾语从句时，要把谓语动词say改为tell或ask。

如：Can tom do the work? Miss Gao said to Tim.==>Miss Gao asked Tim if/whether Tom could do the work.3.疑问词引导的宾语从句当宾语从句时特殊疑问句时，由疑问词来引导，用陈述句语序，即：“主句+疑问词+主语+谓语+…,”疑问词不能省略。

如：Do you know what he has done?Please ask which book is hers.Can you tell me when the plane wii take off?三、宾语从句“一、二、三”1.“一”，指一种语序，从句必须用陈述句语序。

如：Is Mr Wu a teacher? Please tell me.-->Please tell me if/whether Mr Wu is a teacher.What can he do? I say to them.-->I ask them what he can de.2.“二”，指两种时态，即从句的时态要根据主句的时态来确定时态。

宾语从句一、定义及种类定义：宾语从句在复合句中作主句的宾语宾语从句可以作及物动词、介词或形容词的宾语。

及物动词宾语：I don’t know what he likes.介词宾语：We are talking about whether it’s a cat or a dog.形容词宾语：I am sorry I am late. I am glad that you can join us.种类：根据不同的引导词分为三类：that引导：He said that he wanted to stay at home.whether/if引导：He asked me whether/if(是否) he could go.特殊疑问词引导：Can you tell me where the No.3 bus stop is?二、宾语从句——引导词、语序、时态1. 引导词①由_______________引导I don’t know (that) she is seriously ill.I am sure (that) he will succeed.that后加陈述语序，由陈述句变化而来。

这里的that只有语法作用，没有实在的意义，在口语和非正式文体中常省略。

②由_______________引导（其意思是__________）I want to know whether/if she likes Zhengzhou.He asked me whether/if I could help him.whether/if后加陈述语序，由一般疑问句转化而来。

③由_______________引导I don’t know why he loves crying.He asked who was the best.Do you know who (whom) they are waiting for?特殊疑问词后加陈述语序，由特殊疑问句转化而来。

——He asks whether/if we will go fishing on Sunday. 他问我们周日是否去钓鱼。

——Tom wants to know whether/if he needs to come early tomorrow. 汤姆想知道他明天是否需要早点来。

注意：if与whether引导宾语从句时都有“是否”的意思，一般情况下可以互换。

但是在动词不定式之前、介词之后或者句尾有or not出现时，一般只能用whether。

——We haven’t decided whethe r to go or not. 我们还没决定是否会去。
