As soon as的用法解释,举例

1.一经...;立即...;一...就...
as soon as表示一...就,其中的从句通常用一般现在时表示将来时.
这个短语用的比较常用,口语和书面语都可以.它的特点是,在句子中的位置比较灵活,而且可以用于各种时态.例如：
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）.
以下一些双语例句尝试自己书写
Come here as soon as you finish the work.工作一结束你就到这里来.
1.Come here as soon as you finish the work.工作一结束你就到这里来.
2.He jumped out of bed as soon as he was called.一听到有人叫他,他立即跳下床来.
3.Let's talk the matter over as soon as we are conveniently alone.让我们单独在一起的时候再讨论这件事情吧.
4.As soon as Marie opened the door,the dog ran in.当玛丽一打开门,狗就跑了进来.
5.As soon as I stepped inside,my glasses misted over.我一踏进里面,眼镜马上蒙了一层雾.

没有什么特别的用法，意思是尽快，一般写信结尾用i want to hear from you as soon as possible
我想尽快收到你的回信。。。

as soon as ：(adv.)"一...就..."，强调两个动作几乎是连在一起的,后接从句。
1.当主句是一般将来时时，as soon as引导的状语从句应用一般现在时；
2.当主句是过去将来时时，as soon as引导的状语从句应用一般过去时。
有时跟某些单词如与possible相连—"as soon as possible"，其实是as soon as IT ...
