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
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.

回复#1楼的同学
一、宾语从句用法
  时态:   1.主句用一般现在时,从句可用任意时态。可归纳为“主现从不限”   2.主句用过去时,从句用过去某个时态。可归纳为“主过从四过”   3.主句用过去时,从句是科学真理、客观常识、名人格言时用一般现在时。   4.情态动词could/would用于,“请求”,表示委婉、客气的语气时,从句不受主句的约束。   (一)、宾语从句的连接词   从属连词   连接宾语从句的从属连词主要有that,if,whether.   that引导表示陈述句的宾语从句,   if和whether,whether...or not引导表示“是否”的一般疑问句的宾语从句.   He told me (that )he would go to 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.   (二)连接代词   连接代词主要有who,whom,whose,what,whoever,whomever,whosever,whatever,whichever等.   连接代词一般指疑问,但what,whatever除了指疑问外,也可以指陈述.   Do you know who has won Red Alert game   你知道是谁赢得了红色警戒的游戏么?   The book will show you what the best CEOs should know.   这本书会告诉你最好的执行总裁该了解什么.   Have you determined whichever you should buy,a Motorola or Nokia cell phone   你决定好是买诺基亚还是摩托罗拉的电话了吗   (三)连接副词   连接副词主要有when,where,why,how,whenever,wherever,however等.   He didn’t tell me when we should meet again.   他没有告诉我什么时候我们能再见面.   Could you please tell me how you use the new panel   你能告诉我怎么用这个新的操作盘吗   None of us knows where these new parts can be bought.   没有人知道这些的新的零件能在哪里买到.
二、动词的宾语从句
  大多数及物动词都可以带宾语从句   We all expect (that )they will win,for members of their team are stronger.   我们都预料他们会赢,因为他们的队员更强壮.   He told us (that) they would help us through the whole work.   他告诉我们在整个工作中,他们都会帮忙的.   部分“动词+副词”结构也可以带宾语从句   I have found out (that) all the tickets for the concert have been sold out.   我发现这场音乐会的所有票都卖光了.   Can you work out (that)how much we will spend during the trip   你能计算出这次旅行我们将花费多少钱吗   动词短语也可以带宾语从句   常见的这些词有:   make sure确保 make up one’s mind下决心 keep in mind牢记   Make sure that there are no mistakes in your papers before you turn them in.   当你在上交试卷前确保没有任何错误.   可运用形式宾语it代替的宾语从句   ①动词find,feel,consider,make,believe等后面有宾语补足语的时候,则需要用it做形式宾语而将that宾语从句后置②有些动词带宾语从句时需要在宾语与从句前加it   这类动词主要有:hate,take,owe,have,see to.   I hate it when they say with their mouths full of food.   我讨厌他们满嘴食物时说话.   He will have it that our plan is really practical.   他会认为我们的计划确实可行.   We take it that you will agree with us.   我们认为你会同意我们的.   When you start the engine,you must see to it that car is in neutral.   开启发动机时,一定要使汽车的离合器处于空挡位置.   ③若宾语从句是wh-类,则不可用it代替   We all consider what you said to be unbelievable.   我们都认为你所说的是不可信的.   We discovered what we had learned to be valuable.   我们发现我们所学到的东西都是有价值的.
三、介词的宾语从句
  用whether之类的介词宾语从句:   We are talking about whether we admit students into our club.   我们正在讨论是否让学生加入我们的俱乐部. 用that,if引导的介词宾语从句   有时候except,but,besides三个介词后可见到that引导的宾语从句   I know nothing about my new neighbor except that he used to work with a company.   对于我的新邻居我只知道他曾在一家公司上班,其他一无所知.
四、形容词的宾语从句
  常用来引导宾语从句的形容词有: sure,certain,glad,please,happy,sorry,afraid,satisfied,surprised   I am sure I will pass the exam.   我确信我会通过考试.   I am sorry that I have troubled you so long.   很抱歉我这么长时间在打扰你.   He is glad that Li Ming went to see him when he was ill.   他很高兴在他生病的时候李明能去看望他.
五、if,whether在宾语从句中的区别
  ① if和whether在作“是否”解时,引导宾语从句常放在动词know,ask,care,wonder,find out等之后,介词后一般不用if   ② 少数动词,如:leave,put,discuss,doubt后的宾语从句常用whether.   ③ whether后可以加or not,但是if不可以.   ④ 在不定式前只能用whether.   (如:I can’t decide whether to stay. 我不能决定是否留下。)   ⑤ 避免歧异时,我们常用whether而不用if.
六、哪些宾语从句不可以省略引导词that
  当that作learn,suggest,explain,agree,wonder,prove,mean,state,feel,hold等动词的宾语时;   当宾语从句较长时;   当主语状语置于主句尾,宾语从句之前时;   当主语谓语动词(包括非谓语动词)与宾语从句之间有插入语时;   当一个动词带有两个或两个以上宾语从句时,此时第一个that可以省略,第二个that不可以省略;   当宾语从句中的主语是this,that或this,that做主语的定语时;   当宾语从句是双宾语中的直接宾语时;   当宾语从句的主语是非谓语动词或主语从句时;   当主语中的谓语动词是固定词组时;   当宾语从句有it做其先行词时;   在直接引语中,转述分句把宾语从句隔开时.
七、宾语从句的否定转移
  宾语从句的反意疑问句
  主句的谓语动词是think,believe,imagine,suppose,consider,expect,fancy,guess等,并且主句的主语是第一人称而且为一般现在时,从句的否定词一般要转移到主句上来,其反义疑问句一般与宾语从句一致. 如果宾语从句中有某个含有否定意义的形容词或副词,其反义疑问句要用肯定形式.  八、宾语从句的时态和语序
  当主句为现在时或将来时,宾语从句的时态一般不受主句的时态所影响.   当主句为过去时   ①从句用一般过去时或过去进行时表示与主句谓语动词动作同时发生   I only knew he was studying in a western country,but I didn’t know what country he was in.   我只知道他当时在西方的一个国家读书,可不知道是哪个国家.   He asked me if I was reading the story The Old Man and the Sea when he was in.   他问我他进来的时候我是否正在读<<老人与海>>.   ②从句过去完成时表示该动作发生在主句谓语动作之前   He told me that he had told Mary about the meeting already.   他告诉我他已经把有关会议的事情告诉了Mary.   ③从句谓语用过去将来时表示该动作发生在主句谓语动作之后   The reporter asked if the government would take necessary measures to put down the to-do.   记者问政府是否会采取必要的措施镇压骚乱.   ④如果从句是一个客观真理,那么从句的时态不根据主句的时态而变化   The teacher said that the moon goes around the earth yesterday.   老师昨天说月亮围着地球转.   ⑤当宾语从句的引导词是who,which,what,when,where,how,why等表疑问时,不能按正常语序安排,经常将这类引导词置于句首   Who do you think the public might choose as their favorite singer this year   你认为今年公众会选谁为他们最喜欢的歌手.   6.[1]无论任何时候都为陈述语序.
编辑本段宾语从句(版本二)
  学习宾语从句要抓住三要素:连接词、语序和时态。
1.引导词
  1.从句为陈述句,常选择引导词that或将that省略,直接与主句相连。2.从句为一般疑问句,常选择引导词if或whether。在 whether … or not 结构中不能用 if 替换。3.从句为特殊疑问句,常选择what,when,where,which,who,how等的疑问代、副词作引导词。注意:当who为主语时,句式为:who+谓语+其他
2.判断时态情况
  1.主句是一般现在时,从句为各种时态情况。   2.主句是一般过去时,从句为各种相应过去时态注意:从句描绘客观事实,用一般现在时。   3.关系代词:that,who,whom,whose,which   
希望能帮到你。
最后衷心的祝你学业有成。
