如何学习主语从句
1、引导主语从句的连接词有从属连词that, weather, 连接代词who, what, which等等,咒邃狁廖连接副词when, where, how, why等。主语从句在句首时,必须由连接词引导,不能省略这些连接词

3、连接代词引导的主语从句,例如what seems easy to some people seems difficult to others, which side will win is not clear

5、主语从句可以前置,也可以后置,用it作形式主语时,须把主语从句放在句末,常用下面几种句型:it+be+表语(名词,形容词,过去分词)+主语从句
