用于引导名词性从句的引导词有以下几类:连接代词: what。which。who。whom。whose。连接副词: when。where。why。how。一、that,what和which:that引导名词性从句时只起连接从句的作用,本身没有任何意义,因此在从句中不充当任何句子成分,它的使用须注意以下几点:引导宾语从句时,that常可省略,但如果主句后跟有并列宾语从句时,只能省略第一个that,若宾语从句前插有别的从句时,that也不能省略。He told me (that) he was all right and that he would come to see me when he was free. 他告诉我说他很好,并说在他有空时来看我。that引导主语从句位于句首时不可省略,如果it作形式主语,而that从句置于句末,这时that可以省略。
