知识的学习需要的不仅是大量的做题，更重要的是知识点的累积。精品学习网初中频道为大家准备了宾语从句知识点，欢迎阅读与选择!

用作宾语的从句叫宾语从句。宾语从句不仅可以用作及物动词的宾语，还可以用作介词或某些形容词的宾语。宾语从句的语序只能用作陈述句语序。

一、宾语从句的引导词

1.由连词that引导，在口语或非正式文体中可以省略。例如：

He said he would go to Tokyo on business the next day.

注意：

当引导词that引导几个表示并列关系的宾语从句时，最后一个that不能省掉。

2.由if，whether引导，宾语从句属于一般疑问句时，语序一定是陈述句语序。例如：

I wondered if/whether he would come to meet me on time .

注意:

1)if 与whether一般是可以互换的，但在引导由选择疑问句变来的宾语从句时，只可以用whether。

I don't know whether the pen is his or yours.

2)如果宾语从句有or not，也只能用whether引导

I wonder whether he will come to my birthday party or not.

3)由连接代词或副词（who,whose,what,which,when,where,why,how)引导的宾语从句

He wondered what had happened to her.

Can you tell me where the nearest post office is?

二、宾语从句语序

宾语从句要用陈述语序，特别是由疑问句变来的宾语从句要将助动词、系动词移至主语之后或与它的谓语动词合并

“Where do you come from？”he asked.=He asked where you came from.

I don't know what the weather is like there.

三、时态呼应

1.若主句为一般现在时态或一般将来时态，从句的时态不限，可视句子而定，使用所需的任何时态。

We all know chickens can't swim.

She says she will come back.

2.若主句是祈使句，从句也可用所需的任何时态

Show me which picture is yours.

3.主句是一般过去时态，从句必须用过去完成时态

I knew she had swept the floor already.

4.若从句叙述的是客观真理、自然现象或永恒不变的规律时，则不受主句时态限制，仍用一般现在时态。

Our physics teacher told us that light travels faster than sound.

She said one and two is three.

四、否定转移

如果在动词think，believe，suppose，guess之后的宾语从句是由that引导的否定从句，且主句是第一人称，否定要转移到主句上。

I don't believe he is a boy of five years old.

I don't think you are right.
