(2)一般疑问句变为if(whether)引导的宾语从句,如:
He asked me,“Does his father know Mr Green?”

(3)特殊疑问句变为由who, what, where, how等疑问词(连接代词或连接副词)引导的宾语从句,如:
He asked me,“Where is Mr Wang?”
---He asked me where Mr Wang was.
注意上述例句中连词、时态、语序等变化.

一、宾语从句的定义:什么是宾语从句呢?简单地说 就是由一个句子来充当宾语,在句子中起到宾语作用的从句,称之为宾语从句。
二、宾语从句的种类:
(1)动词的宾语从句
(2)形容词的宾语从句
(3)介词的宾语从句
1:下面我们先讲动词的宾语从句,什么是动词的宾语从句呢?顾名思义就是在谓语动词后面的从句,这种形式的从句也分三种不同的形式:
(1)动词后面直接带宾语从句。例如:I hope you can pass the exam. 我希望你能及格。
(2)动词+副词结构后可以带宾语从句。例如:Can you find out what the sentence really means in the text?你能找出来这句话在课文中的真正意思吗?
He asks who is the best student in our class. 他问谁是班上最好的学生?
(3)动词短语后可带宾语从句
例如:Make sure that there are no mistakes in your papers.
在上交试卷前确保没有错误。
2:形容词的宾语从句
就是在形容词后的宾语从句。例如:I am sure that he will be back. 我确信他能回来。
I am afraid that I will be late.
恐怕我要迟到了。
3:介词的宾语从句
就是接在介词后面的宾语从句。例如:I agree with what you said just now. 我同意你刚才说的话。He always thinks of how she can do more for others. 他总是想着如何才能为别人做的更多。
三、宾语从句的引导词:
宾语从句和主句中间的引导词有that ,if /weather 和wh类连接词。
1:其中that引导宾语从句无意义,在从句中不做成分,因此在口语中可以省略。
2:if/weather引导宾语从句时,在句子中不做任何成分,但是有具体含义,它的意思是“是否”,因此不可以省略掉。
3:wh类连接词包括两种
(1):连接代词也叫关系代词,它们有who ,whom,whose,what,which,whoever,whichever.
(2):连接副词也叫关系副词,他们有when,where,why,how,whenever, wherever,however。
四:宾语从句的时态
宾语从句的时态跟主句有关系,要根据主句来判断和决定从句的时态。
(1)主句是一般现在时态,从句可以是任意时态。
(2)主句是一般过去时态,从句是表示过去的时态。
(3)主句是一般过去时态,从句是自然现象,客观真理,恒久不变的事实,从句用一般现在时态。

英语的宾语从句结构
一.宾语从句的定义置于动词、介词等词性后面起宾语作用的从句叫宾语从句.宾语从句的语序必须是陈述语序.谓语动词、介词、动词不定式,v.-ing形式后面都能带宾语从句.有些形容词(afraid,sure,glad等)之后也可以带宾语从句.
二.宾语从句中引导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.
(一)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, declare, report等.
例句:The boy believes that he will travel through space to other planets.
注意事项: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.
例句:I don’t think it is right for him to treat you like that.
在以下情况中that不能省略当句中的动词后接多于两个由that引导的宾语从句时,第一个that可省,但后面的that不可省.
例句:He said (that) you were too young to understand the matter and that he was asked not to tell you.当主句的谓语动词与that宾语从句之间有插入语时,that一般不可省.
例句:Just then I noticed, for the first time, that our master was wearing his fine green coat and his black silk cap.当that从句是双宾语中的直接宾语时,that不可省.
例句:I can’t tell him that his mother died.
注意事项: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.
例句:I don’t think it is right for him to treat you like that.
在以下情况中that不能省略当句中的动词后接多于两个由that引导的宾语从句时,第一个that可省,但后面的that不可省.
例句:He said (that) you were too young to understand the matter and that he was asked not to tell you.当主句的谓语动词与that宾语从句之间有插入语时,that一般不可省.
例句:Just then I noticed, for the first time, that our master was wearing his fine green coat and his black silk cap.当that从句是双宾语中的直接宾语时,that不可省.
例句:I can’t tell him that his mother died.注意事项:许多带复合宾语的句子,that引导的宾语从句经常移到句子后部,而用it作形式宾语.
例句:I find it necessary that we should do the homework on time.
(二)由whether,if 引导的宾语从句由whether(if)引导的宾语从句,实际上是一般疑问句演变而来的.意思是“是否”.宾语从句要用陈述句语序.一般说来,在宾语从句中whether与if可以互换使用,但在特殊情况下if与whether是不能互换的.
例句:I wonder whether(if) they will come to our party.
只能用whether,不能用if引导的宾语从句在带to的不定式前
例句:We decided whether to walk there.
在介词的后面
例句:I’m thinking of whether we should go to see the film.在动词后面的宾语从句时
例句:We discussed whether we had a sports meeting next week直接与or not连用时
例句:I can’t say whether or not thet can come on time.只能用if不能用whether引导的宾语从句if引导条件状语从句,意为“如果”
例句:The students will go on a picnic if it is sunny.
if引导否定概念的宾语从句时
例句:He asked if I didn’t come to school yesterday.引导状语从句even if(即使)和as if(好象)时
例句:He talks as if he has known all about it.
(三)连接代词和连接副词引导的宾语从句这样的宾语从句实际上是由特殊疑问句变化而来的,宾语从句要用陈述句语序.用于这种结构的动词常常是:see, say, tell, ask, answer, know, decide, show, find out, imagine, suggest, doubt, wonder, discover, understand, inform, advise等.
英语中的连接代词有:who,whom,whose,which,what,在句中担任主语、宾语、定语或者表语.
例句:Can you tell me whom you are waiting for?
英语中的连接副词有:when,where,why,how,在句中担任状语的成分.
例句:None of us knows where these new parts can be bought.
三.宾语从句的语序宾语从句的语序是陈述句语序即:连接代词/副词+主语+谓语+其他成分.例句如下:
I don’t know what they are looking for.Could you tell me when the train will leave?Can you imagine what kind of man he is?
四.宾语从句的时态主句是一般现在时,从句根据实际情况使用任何时态.
例句:The headmaster hopes everything goes well.主句是过去时态,从句须用过去时态的某种形式.
例句:She was sorry that she hadn’t finished her work on time.当宾语从句表示的是一个客观真理或者事实时,即使主句是过去时,从句也用一般现在时态.
例句:The teacher told his class that light travels faster than sound.
五.宾语从句的特点宾语从句可以作及物动词、介词及形容词的宾语.宾语从句的语序一律用陈述句语序.连接词that引导宾语从句在句中无词义,不充当句子成份,多数情况下可以省略.whether 和 if 都可引导宾语从句,但 whether后可紧跟or not;whether从句可作介词的宾语.如果从句太长,可以用形式宾语it.
英语的宾语从句有哪些?
一、由that引导(that可省略):主语+that+陈述句
Eg.I know that he was right.我知道他是对的。
二、由if引导:If+…(if,是否)(或用whether)
Eg.I don't know if he is a student.我不知道他是否是一位学生。
三、由wh-疑问词引导:当宾语从句由一 般疑问句充当,将wh-疑问词保留句首并把后面的部分改成陈述语序
Eg.原句:Why are you late?You should tell me.
wh-疑问词引导:You should tell me why are you late.
主句为一般现在时,从句可以是任何时态
主句为一般过去时,从句时太需要变化。
