宾语从句 在句中担当宾语的从句叫宾语从句，宾语从句可作谓语动词的宾语，也可做介词的宾语。 eg：He said he was good at drawing. (动词宾语) He asks him how long Mike has been down . (动词宾语) Miss Zhang is angry at what you said. (介词宾语) 宾语从句的引导词有三类： (1)以that 引导的宾语从句，主要用来引导句形式的宾语从句， that可以省略。 eg：The radio says (that) the clouds will lift later on. She told me (that) she would like to go with us. (2)以连接代词which, what, who等或连接副词how, where, why 等引导的`宾语从句，从句是陈述语序 eg：Could you tell me what’s the matter with u? I want to know how soon it will begin. (3)以 whether 或 if 引导的宾语从句, 主要用来引导一般疑问句意思或选择疑问句意思的宾语从句，从句同样是陈述语序 eg：I wonder if /whether u have told the new to Li Lei . 宾语从句的时态 (1)当主句为一般现在时态、现在进行时态、或一般将来时态时，从句可用所需要的任何时态。 eg, I want to know what time he got up this morning. You are telling me that you won’t stop until tomorrow? (2)当主句为一般过去时态时， 从句要用于过去有关的时态。 eg：They asked what Jean was doing now . Linda said that the train had left. (3)当从句表述的是客观真理或自然现象时，宾语从句要使用一般现在时。 eg：Lisa asked whether light travels faster than sound. Polly said no news is a good news 注意：一般情况下，whether 和if 可以互用， 但有些情况例外。 1.当从句做介词的宾于是只用whether 不用if eg：We are talking about whether we’ll go on the pinic. 2.引导词与动词不定式或 not 连用时， 只用whether. eg：Please let me know what to do next. Could you tell me whether u go or not? 3. if当如果讲时，引导的是条件状语从句，这时不能用whether. eg：You can’t work the plan out if you don’t have the meeting .

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。下面是我整理的初中英语宾语从句知识点，欢迎大家分享。
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, propose, 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
1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.
2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.
3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t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
1在带to的不定式前
例句：We decided whether to walk there.
1在介词的后面 例句：I'm thinking of whether we should go to see the film.
2在动词后面的宾语从句 例句：We discussed whether we had a sports meeting next week
3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
1if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.
2if引导否定概念的宾语从句时 例句：He asked if I didn't come to school yesterday.
3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：1 I don't know what they are looking for. 2 Could you tell me when the train will leave?
3 Can you imagine what kind of man he is?
四.宾语从句的时态
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.
3 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
1宾语从句可以作及物动词、介词及形容词的宾语。
2宾语从句的语序一律用陈述句语序。
3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。
4whether 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。
5如果从句太长，可以用形式宾语it.
