注意：since then表从过去某一点时间延续至说话时，强调到目前为止一直进行的动作或者保持的状态。所以句中谓语动词一般用现在完成时或者现在完成进行时。例如：
1、After that he never passed any test.1.从那以后他任何考试都从未及格过。
2、After that they took more attention to the action.2.从那以后他们对我的行动更加关注了。
3、I have been working hard since then.3.从那以来我一直努力工作。
4、Since then he has been drawing a pension.4.从那时起他一直领退休金。
5、She 's been studying hard since then.5.打那儿起，她就用心念书了。
6、It had been intolerable to be with him since then.6.从此跟他在一起就如坐针毡。
as soon as 一般指未发生的动作,主句一般将来时,从句用一般现在时代替一般将来时。例如：
1、I will tell him the news as soon as he comes back.他一回来我就告诉他这个消息。
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.例如：
2、I will go with you as soon as I have washed my face.我洗完脸就和你一起去。
当as soon as指紧接着发生的两个短动作,主从句都用一般过去时。例如：
1、He took out his English books as soon as he sat down.他一坐下就拿出了英语书。
不过,我也见过从句和主句都用一般现在时的情况.例如：
2、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.
