一、定义：在复合句中用作宾语的从句叫宾语从句。二、详解：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。例如：Liu Ping found that there was a wallet lying on the ground. → Liu Ping found a wallet lying on the ground.方法六：动词seem后的宾语从句，也可以用不定式（短语）来简化，但句型需要进行适当的变化。例如：It seemed that the boys were going to win. →The boys seemed to win.除上述方法外，还有一些特殊句式的转化。例如：I found that it was difficult to learn English well. →I found it difficult to learn English well.Soon we found that the ground was covered with thick snow. →Soon we found the ground covered with thick snow.They found that the box was very heavy. →They found the box very heavy-----回答参考了圣才学习网资料

宾语从句宾语从句，是名词性从句的一种。在主从复合句中充当宾语，位于及物动词、介词或复合谓语之后的从句称为宾语从句。宾语从句分为三类：动词的宾语从句，介词的宾语从句和形容词的宾语从句。[1]中文名宾语从句外文名Object

They know (that) he is working hard. 具体过去永不变，真理格言现在时；eg． He told me that he was born in 1980. Father told me that practice makes perfect .（2）否定前移，及完成反意问句； 在think / believe / suppose / guess / imagine / expect等动词后跟宾语从句否定式时，应转移到主句上去，完成反意问句时，应与从句主、谓保持一致。（注: 否定前移的条件是，主句主语是第一人称）eg． I don't think you are right ,are you ? I don't believe they have finished their work yet,have they ?（3）在表示建议 suggest , advise 要求demand 、desire、require、request、propose； 决定 decide; 命令 order、command; 坚决主张 insist; 等动词后跟宾语从句，用（should）+v．（虚拟语气）eg． I suggested that you（should）study hard． He ordered that we should go out at once．（4）如果宾语从句后有宾语补语，用it作形式宾语，把宾语从句后置eg．You may think it strange that he would live there．（5）宾语从句that常可省略，但在以下情况下不能省略A．当主句谓语动词带有两个或两个以上宾语从句时，可以省略第一个that，其他不能省略。eg．I believe（that）you have done your best and that things will get bet?．B．当it作形式宾语时eg．She made it clear that she had nothing to do with him．C．当宾语从句前置时eg．That our team will win，I believe．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.主句是一般过去时，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真理时，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.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。即：连接代词/副词+陈述句语序。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?用法宾语从句宾语从句的连接词：that结构：主语+谓语+宾语（陈述语序）

宾语从句是在从句中充当宾语的从句叫做宾语从句，下面就是我给大家带来的中考英语语法专题详解十二：宾语从句，希望能帮助到大家!
考点聚焦
一、什么是宾语从句
在句中充当宾语的从句叫作宾语从句，宾语从句可作谓语动词的宾语，也可作介词的宾语。
二、宾语从句的引导词
1、 that 无实意，用来引导陈述句的宾语从句，口语中常省略。例如：
She told me that she had been to Hong Kong twice.
她告诉我她去过香港两次。
I know(that)the visitors are from Australia.我知道这些游客来自澳大利亚。
2、if或whether这两个词是“是否”的意思，主要用来引导一般疑问句或选择问句的宾语从句，口语中多用if，不能省略。例如：
He asked me if / whether I had been to Beijing twice.
他问我是否去过北京两次。
She wanted to know whether I would go there or not.
她想知道我是否想去那里。
3、疑问词when ，where，who，how等，这类词通常引导特殊疑问句的宾语从句。例如：
Can you tell me how I can find Mr Wang?
你能告诉我怎样才能找到王先生吗?
Please find out who broke the window.请查一下是谁打烂窗户的。
三、宾语从句的语序
凡是从句都必须使用“主语在前，谓语在后”的陈述语序，宾语从句也不例外，也就是说宾语从句的语序必须是“引导词+主语+谓语+ 其它 ”。例如：
误：Could you tell me where is the bus station?
正：Could you tell me where the bus station is?
四、宾语从句的时态一致
1、 当主句为一般现在时或一般将来时的时候，从句可以根据需要选择相应的时态，不受主句的影响;主句为一般过去时，从句要用相应的过去时态。例如：
I want to know what time he ate his breakfast.
我想知道他今天早晨几点钟吃早饭的。
They will tell us that they have been able to look after themselves.
他们将会告诉我们他们已经能照顾自己了。
I asked what my father was doing then.
我问那时我爸爸在干什么?
2、 当宾语从句表述的是客观真理或自然现象是，宾语从句的时态不受主句的时态的影响，仍然用一般现在时。如：
He said the moon moves round the earth.
他说月亮围着地球转。
She asked whether light travels faster than sound.
她问光速是否比声速快。
五、宾语从句的简化
由特殊疑问词引导的宾语从句中的主语与主句的主语或宾语相同时常常可以将宾语从句简化成“特殊疑问词+动词不定式”这种结构。有时候由that引导的宾语从句也可以用动词不定式或者动词的ing形式来简化。如：
Can you tell me how I can get to the post office?
= Can you tell me how to get to the post office?
She don’t know whether she should go there with them or not.
= She don’t know whether to go there with them or not.
He can remember that he has climbed the tall tree.
= He can remember climbing the tall tree.
六、宾语从句的否定转移及其它
1、当I think/believe/guess等一些看法的词后面所接的宾语从句是否定句时，习惯上否定主句，采用“I don’t think/believe/guess+肯定形式的宾语从句”这种结构来表达。如：
我认为明天她不会来。
误：I think that she won’t come tomorrow.
正：I don’tthink that she will come tomorrow.
2、 对I think/believe/guess等动词后面所接的宾语从句进行划线部分提问时，要用“疑问词+do you think /believe/guess+宾语从句的剩余成分?”这种结构来表达。如：
你认为谁将在会上发言?
误：Do you think who will speak at the meeting?
正：Who do you think will speak at the meeting?

宾语从句，是名词性从句的一种。在主从复合句中充当宾语，位于及物动词、介词或复合谓语之后的从句称为宾语从句。宾语从句分为三类：动词的宾语从句，介词的宾语从句和形容词的宾语从句。宾语从句1.that引导宾语从句无意义,不充当句子成分常省略.但下列情况除外：（1）介词宾语从句的that不省略（2） and连接的几个从句,第二个从句以后的从句的that不省略.He told me that he had two sons and that they both had gone to college.（3）在动词+it+宾语补足语+宾语从句结构中,that不省略.I heard it said that he had gone abroadWe found it impossible that he could finish it in such a short time2.Whether ,if 引导宾语从句：两词可互换,但是下列情形除外：（1）whether从句中有or not（2）whether从句做介词宾语Everything depends on whether you agree with us3.许多带复合宾语的句子,宾语从句经常移到句子后部,而用it做形式宾语.结构常是：主语+动词+it+形容词/名词等宾语补足语+宾语从句We think it wrong that he told a lie to everyone扩展资料：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。时态：1 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.2 主句是一般过去时，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.3 当宾语从句表示的是一个客观真理或者事实真理时，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 t
