1.宾语从句在句中作及物动词或介词的宾语,从句放在主句之后,前后不用逗号分开。
2.引导宾语从句的词有:
连词that(在口语中that常可省略),if, whether,如:
He knows that Jim will work hard.
连接代词who, whom, which等,如:
Do you know who (whom) they are waiting for?
连接副词when, where, how, why等,如:Could you tell me how we can get to the station?
3.whether和if都有“是否”的意思,一般情况下两者可以换用,但在介词之后,
不定式之前,与or not连用,在句首或在引导表语从句,同位语从句时,只能用whether,如:I want to know if/whether the news is true. He doesn't know whether to stay or not?
4.宾语从句要用陈述句语序。
5.宾语从句一定要注意时态呼应,即:当主句谓语动词是过去式时,从句中谓语动
词也要用过去范畴的时态,但若从句陈述的是真理或客观规律,其谓语的时态仍用一般现在时,如:
He asked who could answer the question.
My father told me that the earth goes around the sun.
6.一个宾语从句只能用一个连词。
7.当主句谓语动词是think, believe等动词时,宾语从句的否定意义要放到主句中。另外,当主句主语为第一人称时,后面若接附加疑问句,那么附加疑问句的主语、谓语应与从句中的主谓语保持一致。如:
I don't think he looks like his father, does he?
8.直接引语和间接引语也是宾语从句,直接引语是引述别人的原话,放在引号内,
不用连词联接;间接引语是用自己的话转述别人的话,通常用连接词与主句联接。
(1)陈述句变为以that引导的宾语从句,如:
He said,“I'm happy.”[FY()[FY]]He said that he was happy.
(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?”
---He asked me if his father knew 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。

可用 that whether if whose why
{which what who whom where how when 和这些词后加 ever}引导
放在 宾语位置
跟在 动词(非系动词),介词 后
跟在特殊形容词后 :sure certain afraid glad pleased happy surprised satisfied sorry
suggest advise order insist demand ask 后用虚拟语气 即+(that)+sb +(should) +do

一般句子的主要成分都是主语谓语宾语,从句的意思是句子里面还有句子,宾语从句就是说由一段句子作宾语的句子,一般由that引导。如:I don't think that I can do it.that后面为宾语,它也可单独作为一个句子。
