1 名词性从句 在复合句中起名词作用的从句叫做名词性从句。名词性从句的作用相当于名词，因此主语从句、表语从句 、宾语从句和同位语从句分别作主句的主语、表语、宾语和同位语。 主语从句：Who will win the match is still unknown. 宾语从句：I want to know what he has told you. 表语从句：The fact is that we have lost the game. 同位语从句：The news that we won the game is exciting. 引导名词性从句的连接词可分为三类： 连接词(不充当从句的任何成分)：that ,whether ,if 连接代词：what, who, whom, whose, which, wh+ever 连接副词：when ,where ,how ,why Object Clau ses 宾语从句 一、宾语从句的概念：宾语从句在复合句中作主句的宾语。 位置：通常放在主句谓语动词（及物动词）或介词之后。 句子结构：主句 +连词(引导词)+ 宾语从句 e.g. She asked if these answers were right.
