as soon as用法:
英语中的时态一般分为两种:现在时态,过去时态。
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。
