主语＋will do sth+as soon as+主语＋do sth；主语＋did sth+as soon as 主语＋did sth。as soon as 翻译为“一...就...”所以动作一般有个先后顺序。
具体用法
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.
一般来说as soon as前后的动词用主将从现，主句用一般将来时，从句用一般现在时。
