表语从句because怎么用That he didn't turn up was because he had to accompany his mother.是不是because引导的表语从句?还有一句是The reason why he didn't turn up was that he had to accompany his mothe.为什么不用because?求that,
表语从句because怎么用
That he didn't turn up was because he had to accompany his mother.
是不是because引导的表语从句?
还有一句是The reason why he didn't turn up was that he had to accompany his mothe.为什么不用because?
求that,why 与 because 引导表语从句时的区别,以及在其他名词性从句中的用法

第一句：that he didn't turn up 是一个主语从句,because引导表语从句
第二句：the reason 后常跟why引导表语从句,that引导表语从句.可以把它当句型来记.
The reason why-定语从句 is that-表语从句.
注意：主语是the reason 时,后面的表语从句不用because 引导.
that 引导名词性从句时在从句中不做句子成分,没有含义.只起连词的作用.
because 引导表语从句时的句型是：This is because-从句.
当why引导名词性从句时要有本身的含义.例如：
I don't know why he is late.
第一句话对的，that作he didn't turn up 的同位语，句子的主干就是that was because
下面一句的主干就是the reason was that..如果用because就不通了，why...是作the reason的定语
