as soon as 的用法一般是两种情况: 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(比如后面从句里用了将来时,就绝对允许了). 感谢你向我们团队求助,
