同位语从句和定语从句有啥相同的
why引导的同位语从句与定语从句的区别？
why引导的同位语从句与定语从句的区别？
why引导定语从句，先行词只有一个，就是The reason如：The reason why he was late was that he got up late this morning.而why引导同位语从句，一般只在have no idea之类的句式中出现。如：I have no idea why he was late.其实，在这种句式中have no ideadont know的意思。所以，有些语法书上并不把这类从句算作同位语从句的。
名词性从句，定语从句，同位语从句有什么区别？
首先，名词性从句包括同位语从句。
名词性从句，顾名思义，起到名词作用的从句，在句子中可直接做主语、宾语、表语、同位语。定语从句，具有形容词的特点，常用来修饰名词或代词。被修饰的名词或代词叫做先行词。
同位语从句和定语从句的关系先行词有什么不同？
定语从句是修饰限定先行词 I heard of a piece of news which made me very excited 同位语是说明前面名词的具体内容 I heard of a piece of news that London Olympics would start soon.
定语从句和谓语从句的区别？
没有谓语从句，这里做定语从句和同位语从句的区别。
定语从句 的先行词在从句中充当成分,同谓语从句的先行词在从句中不充当成分.这是最容易的区分方法.
eg: I was told the news that was published in the newspaper.(这里定语从句的先行词that在从句中做主语)
I was told the news that the president had been murdered.(这里同谓语从句的先行词that在从句中不充当成分,只是引导从句.)
同时同谓语从句的先行词只有that而且不可以省略,定语从句的先行词有多种形式,如that which where whose how..等等)
