关于as soon as
我在网上看到as soon as的用法,但是看了一个例子又觉得有些奇怪
在时间状语从句中,主句用一般将来时,从句用一般现在时.
as soon as 一……就……,引导的就是时间状语从句；
I am going to watch TV as soon as I finish my homework.在此句中,I am going to watch TV 就是一般将来时,I finish my homework这的finish是一般现在时.用finished 肯定不对.
英语中的时态讲究主从句时态一致!除非从句所陈述的为客观事实或真理.如：
The teacher said the sun is bigger than the earth.
He is going as soon as he has had dinner.在此句中,he has had dinner为现在完成时,同样属于现在时态.
我想问的是：它第一句不是说了as soon as ,在时间状语从句中,主句用一般将来时,从句用一般现在时.但是上面有一句例句；He is going as soon as he has had dinner
,我看了这一句就奇怪,为什么用了将来时,还可以用过去完成时?

在He is going as soon as he has had dinner 这句话中, “he has had dinner ”是现在完成时态,不是过去完成时,he had had dinner 才是过去完成时的表达.在as soon as 引导的时间状语中,主句是一般将来时,从句要用一般现在时代替将来时,现在完成时同样属于现在时态.
