宾语从句在复合句中用作宾语的从句叫做宾语从句。
它是众多从句中的一员，在复合句中作主句谓语动词、介词或某些形容词的宾语。
在及物动词的后面可以接一个名词来充当宾语，如：I know the man.而这时也可以用一个句子来充当宾语，如：I know that the man is a policeman.主句引导词从句宾语从句三大块: 1. 引导宾语从句的连词和代词选择； 2. 宾语从句的语序； 3. 宾语从句的时态。
Ⅰ.宾语从句的引导词1.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：My teacher said I was a good boy.老师说我是个好男孩。
She doesn’t know (that) she is seriously ill. I am sure (that) he will succeed.用以下开头与下列句子连成宾语从句:1. I know …2. She says …3. Tell yo ur friend …（that）1.This is a book.2.You like singing.3.He worked last night.4.They will go home.5.Jim has been to Beijing.6.She sings well.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：(1) Is Jim a good student? I don’t knowI don’t know if /whethe r Jim is a good student.(2) Does Kate get up early? Do you know?Do you know if /whether Kate gets up early?用以下开头与下列句子连成宾语从句:1.Do you know …2.I want to know …3.The teacher asks …if/whether1.Is he reading ?2.Do you get up at six?3.Does Tom work hard?4.Did you watch TV ?5.Will they read books ?6.Can you sing ?注意：只能用whether不用if 的三种情况•一般情况下，if 和whether可以互换，但以下3种情况只能用whether：•①与or not连用：He asked me whether or not I was coming. Let me know whether you can come or not.•②在介词之后：It depends on whether it is going to rain. I worry about whether I hurt her feelings •③在不定式之前：We haven’t decided whether to go there. I don’t know whether to accept or refuse.3.如果宾语从句原来是特殊疑问句，只需用原来的疑问词引导。
如：1.What is she doing? Can you tell me?Can you tell me what she is doing?2.Where does she live? Do you know?Do you know where she lives?用以下开头与下列句子连成宾语从句:1.Do you know …2.I want to know …3. Can you tell me …1.What is this ?2.What are you doing ?3.Where do you live ?4.When does he get up ?5.How did you go to work?6.Who will you play with?Ⅱ.宾语从句的语序必须是陈述语序注意事项:(一)当从句的原句为以下句子以及what, who作主语时，语序不变：What’s wrong? What’s the matter?What’s happening?eg:I don’t know what’s the matter.Can you tell me who is over there?Ⅲ.宾语从句与主句的时态要相互呼应1. 如果主句的时态是一般现在时，宾语从句的时态根据具体情况来确定，可以是_________时态。
I don’t think (that) you are right.Please tell us where we’ll go fishing tomorrow.Do you know when Mr. Smith moved here?2. 如果主句的时态是一般过去时，宾语从句只能用相应的_________时态（一般过去时，过去进行时，过去将来时，过去完成时）。
例如：He told me that he was born in Beijing in 1992.He said that he would go back to the U.S. soon.特殊情况：1.从句说明的是一般真理、客观事实、自然现象、名言时，任用现在时。
Dad told us that it is better to do than to say.He told the boy that three and three is six.Could you tell me where the bookshop is.2.从句中有具体时间状语，即使从句动作发生在主句动作前，仍然用一般过去时。
The teacher told me she was born in 1960. 二、宾语从句的转化1.2. 当主句谓语动词是hope，wish，decide，forget，plan，agree等，且主句主语与从句主语相同时，从句可简化为不定式结构。
如：She agreed that she could help me with my maths.→She agreed to help me with my maths.2.当主句的谓语动词是know, learn, forget, remember, decide等后面带特殊疑问句转化的宾语时，主从句的主语也须一致这时从句可以简化成“疑问词＋不定式结构”。
例如：I don't know which sweater I should buy.→I don't know which sweater to buy.3.当主句的谓语动词是ask，tell, show, teach等后面带双宾语时，从句的主语和间接宾语一致，且从句是由特殊疑问句转化来时，从句可以转化成“疑问词＋不定式结构”,或者在连接代词/副词引导的宾语从句中，当从句主语与主句主语或间接宾语一致时，宾语从句可简化为“连接代词/副词＋不定式”结构。
如：→Could you tell me how to get to the park?4. 当主句谓语动词是find，see，watch，hear等感官动词时，从句常简化为“宾语＋宾补”结构，宾补为不带to的不定式或V-ing形式。
如：She found that the wallet lay/was lying on the ground.→She found the wallet lie/lying on the ground.[即学即练]子连接成为含有宾语从句的复合句。
