名词性从句在复合句中具有名词的性质的作主语、表语、同位语、宾语的从句叫名词性从句。因此，我们把主语从句、表语从句、同位语从句和宾语从句这四种从句统称为名词性从句。

主语从句(subject clauses)在复合句中起主语作用的从句叫主语从句。引导主语从句的词有从属连词、、关系代词、连接副词等。引导主语从句的关联词有从属连词that、whether，关系代词：who, what, which , whom, whose, whatever, whoever, whomever, whichever；关系副词：when, where, how, why, however, whenever, wherever等。

表语从句用作表语的从句叫作表语从句，它位于主句中的连系动词之后。引导表语从句的

词有从属连词that、whether、as though(if)；关系代词who, what, which, whom, whose, whatever, whoever, whomever, whichever等；关系副词when, where, why, how, however, whenever, wherever等。可以接表语从句的连系动词由be, look, remain, seem等。That引导表语从句时，在口语中，间或可以省略。

宾语从句(object clauses)用作宾语的从句叫做宾语从句。宾语从句的位置与陈述句基本结构中的宾语相同。宾语从句可作谓语动词的宾语，也可以作介词和非谓语动词（动词不定式、动名词、分词）和某些形容词的宾语。宾语从句可以由从属连词that whether、if，关系代词what, who, whose, which和关系副词when、where、how、why等引导。

information, question等之后，对这些名词进行说明或解释。引导同位语从句的词除连词that，whether外，还有关系代词what, which, who, 以及关系副词how，when，where，why 等。
