as soon as
中文为:一……就……;一经;不久后,一会儿。
既可以引导时间状语从句,表过去,又可以表示将来。
as soon as引导时间状语从句当主句用一般过去时时,从句中用一般过去时或过去完成时。
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。
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,就绝对不允许了)。
