名词性从句的种类
在复合句中充当主语的从句叫主语从句。

在复合句中作表语的从句叫表语从句。引导表语从句的关联词与引导主语从句的关联词大致一样，表语从句位于连系动词后，有时用as if，because等引导。其基本结构为：主语＋系动词＋从句。

The reasn why he was late was that he missed the train by ne minute this mrning.他迟到的原因是，今天早晨他晚了一分钟而错过了火车。
同位语从句说明其前面的名词的具体内容。同位语从句通常由that引导，也可由其他连接代词或连接副词引导，可用于同位语从句的名词有：advice，demand，dubt，fact，hpe，idea，infrmatin，message，news，rder，prblem，prmise，questin，request，suggestin，truth，wish，wrd等。
