as soon as后跟什么时态？ 如何使用？

as soon as后一般跟一般现在时和一般过去时。

因为词组的意思是：一……就……，引导时间状语从句。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如果表示过去的状态，后面就要用一般过去时。

指未发生的动作，规律是：主句一般将来时，从句用一般现在时代替一般将来时

如：I will tell him the news as soon as he comes back。

注：有时，为了特意表达刚刚完成某事就如何如何，需要用现在完成时。

如：I will go with you as soon as I have washed my face.

句法结构

肯定形式

主语+动词过去式+其它

例句：She came to help us in those days．

否定形态

主语+didn't +谓语动词原形+其它

在行为动词前加didn't，同时还原行为动词

例句：I didn't know you like coffee.

以上内容参考：百度百科-一般过去时

As soon as I finish my college study.
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.

as soon as后一般跟一般现在时和一般过去时。
