升高二英语名词性从句之主语从句姓名： 年级： 老师： 刘琳 学习过程一、主语从句的概念与类型 主语从句在复合句中作主句的主语,引导主语从句的词有从属连词 that, whether 以及连接代词who, what, which, whoever, whatever, whichever 和连接副词 when, where, why, how 等.一、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。That he will win is certain.他肯定会赢。Whether he’ll come here isn’t clear. 他是否会来这里还不清楚。注意: 由 that 引导的主语从句有时为了使句子结构平衡, 避开 “头重脚轻”, 常用 it 作形式主语, 而把从句放在后面。 例如: 1.
