专题:
as soon as用法：指未发生的动作，主句用一般将来时，从句用一般现在时代替一般将来时。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两种用法
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。
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）。
