一、名词性从句的分类：

主语从句、宾语从句、表语从句、同位语从句

二、主语从句

（一）定义：用作主语的从句叫做主语从句。

（二）引导主语从句的关联词有三类： （1）从属连词that、whether。如：

eg: That they were in truth sisters was clear from the facial resemblance between them.

很明显，她们确是亲姐妹，她们的脸型很相似。 eg: Whether he’ll come here isn’t clear.

他是否会来这里还不清楚。 从属连词：that, whether等.

that 引导主语从句只起引导作用，本身无实际意义，在主语从句中不充当任何成分，但不能省略。

由whether及其他连词引导的主语从句放在句首，句后都可。 If只能放在句中。

造句：

1、很明显他是个好人。

2、他通过了考试让妈妈很高兴。

3、天气是否会转晴还不确定。 （2）（特殊疑问词）连接代词wh

（1） 在由连词that, whether, if引导的名词性从句中，引导词在句中不做成分，在宾语从句和表语从句中，that可以省略。

（2） 在由连接代词who, whose, whom, which, what, whoever, whomever, whichever, whatever引导的名词性从句中，其连接代词在句中起名词性作用，担当一定成分。

（3）在由连接副词when, where, why, how引导的名词性从句中，其连接副词在句中作状语。

2．whether和if的区别

（1）whether在引导的主语从句中可以置于句首，而if则不能。

（2）whether可以与or not连用，or not可以紧跟在whether之后，也可以置于从句末尾；if一般不能和or not连用。
