什么是宾语从句

宾语从句是名词性从句的一种。在主从复合句中充当宾语，位于及物动词、介词或复合谓语之后的从句称为宾语从句。宾语从句分为三类：动词的宾语从句，介词的宾语从句和形容词的宾语从句。

语法说明

1、that引导宾语从句无意义,不充当句子成分常省略.但下列情况除外：

（1）介词宾语从句的that不省略；

（2）and连接的几个从句，第二个从句以后的从句的that不省略；

He told me that he had two sons and that they both had gone to college.

（3）在动词+it+宾语补足语+宾语从句结构中，that不省略。

I heard it said that he had gone abroad.

We found it impossible that he could finish it in such a short time.

2、Whether,if 引导宾语从句：两词可互换,但是下列情形除外：

（1）whether从句中有or not；

（2）whether从句做介词宾语。

Everything depends on whether you agree with us.

3、许多带复合宾语的句子,宾语从句经常移到句子后部,而用it做形式宾语。结构常是：

主语+动词+it+形容词/名词等宾语补足语+宾语从句

We think it wrong that he told a lie to everyone.
