不能 ,虽然在主从复合句原因状语从句中我们说表示原因有as,for,since,because这几个词,但是他们都在语气盒用法上有很大区别的
语气上 because最强,然后是as ,再是for,最后是since.
用法上,for 一般只能放在句中,表原因.并含有通过现象推测的含义.
since语气最弱,有‘既然'的意思.
as,表原因既可以放在句首也可以放在句中,但语气弱于 because.
既然是强调原因的强调句当然用because最强最合适.
强调原因一般那只能用because 和why 两个词取决于后面接的是原因还是原因导致的结果.若是原因则用because,若是结果用问why 可替换
she was seriously ill;that is why she didn't come to the lecture yesterday.后面是个表语从句
在强调句it is +强调部分句型中我们常用 it was because.句型所以用 it was because she was seriouslyill that she didn'tcome to the lecture yesterday
