一：什么是名词性从句
名词性从句在句子中起到名词的语法功能，可以在句子中做主语（主语从句），可以做宾语（宾语从句），可以做表语（表语从句），还可以做同位语（同位语从句）。名词性从句中的同位语从句与定语从句，在形式上比较相似，难以区分。定语从句是对先行词起到修饰或限定作用，而同位语从句中的同位语名词一般为抽象名词，同位语是对前面抽象名词内容的具体化。另外，定语从句与同位语从句是两个不同性质的从句，其从句连接词是不一样的，比如 that,在定语从句中是代词，而在名词性从句中，只是连接词。
二.名词性从句的连接词
名词性从句的连接词跟定语从句的关系词的功能差不多，名词性从句的连接词也起到连接主句与从句的作用，其功能也包括语法功能与表意功能。但是，名词性从句的连接词与定语从句的关系词不一样，而且其用法比关系词更复杂。名词性从句连接词及其功能如下表：
