一、表语从句 1．在复合句中作主句的表语，位于主句系动词之后。 2．表语从句的引导词与主语从句相同，另外还有as if/as though(似乎，好像)及because等 注意： ①引导表语从句表原因，只能用because，不可用as，since： This is because he loves arts. 这是因为他热爱艺术 ②主句主语是reason时，表语从句引导词用that，不用because： The reason why he was late was that he missed the first bus.他迟到的原因是没赶上头班车。 1.The reason ________ Sun Haiping explained ________ Liu Xiangs quitting the competition was ________ Lius leg hurt badly.
