as soon as的用法归纳总结
as soon as的用法归纳总结如下:
1、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。
2、当主句是过去将来时,as soon as引导的:状语从句使用一般过去时。
3、指紧接着发生的两个短动作,主从句都用一般过去时。
as soon as意为“一……就………”强调两个动作几乎是连在一起的,后接从句。当主句是一般将来时,as soon as引导的状语从句应用一般现在时;当主句是过去将来时,assoon as引导的状语从句应用一般过去时。
举例
1、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.
2、指紧接着发生的两个短动作,主从句都用一般过去时。
如 He took out his English books as soon as he sat down.
不过,我也见过从句和主句都用一般现在时的情况。
如:As soon as he finishes his classwork, he runs out of the class.他一做完课堂作业,就跑出了教室。
总之,记住那两种基本的情况,不把时态用得太混乱了就行了。
