3．由whether 引导的同位语从句

4．由连接代词引导的同位语从句

6．同位语从句与定语从句的区别

(1)从意义上讲，同位语从句是名词性从句，用于对其前面的名词作进一步的说明和解释，与该名词是同位的关系；而定语从句是用来修饰先行词，是从属的关系。

(2)从结构上讲，that在同位语从句中为连词，不充当句子成分；而在定语从句中that代替先行词在从句中充当主语、宾语等句子成分。

(3)有些引导词如whether，what，how等可以用来引导同位语从句，但它们不能用来引导定语从句。

(4)后接同位语从句的名词比较有限，常见的有doubt，fact，message，proof，opinion，hope，impression，evidence，idea，belief，feeling，conclusion，rumour，report，possibility，guarantee，thought，assurance等。而后接定语从句的名词(即先行词)则比较广泛，包括大部分名词及代词。
