as soon as引导的时间状语从句的规则:若主句为一般将来时,从句常用一般现在时表将来;若主句不是一般将来时,那么从句的时态就要根据上下文来定。
as soon as的用法
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.
