14、同位语从句与定语从句的区分。 1 定语从句中的that既代替先行词，同时以在从句中作某个成分主语或宾语，而同位语从句中的that是连词，只起连接主句与从句的作用，不充当句中任何成分。 2 定语从句是形容词性的，其功能是修饰先行词，对先行词加以限定，描述定的性质或特征；同位语从句是名词性的，其功能是对名词进行补充说明。例如： 1 The news that he told me is that Tom would go abroad next year.他告知我的消息是汤姆明年将出国。第一个that引导的从句是定语从句，that在从句中作宾语 2The news that Tom would go abroad is told by him.汤姆将出国的消息是他讲的。同位语从句，that在句中不作任何成分 。 PREV ARTICLE高三英语学问点必修二：since从句的用法NEXT ARTICLE高三英语语法专题复习说课稿：情态动词
