as soon as引導(dǎo)的時(shí)間狀語從句的規(guī)則：若主句為一般將來時(shí)，從句常用一般現(xiàn)在時(shí)表將來；若主句不是一般將來時(shí)，那么從句的時(shí)態(tài)就要根據(jù)上下文來定。

as soon as的用法

1、指未發(fā)生的動(dòng)作,規(guī)律是：主句一般將來時(shí),從句用一般現(xiàn)在時(shí)代替一般將來時(shí)

如：I will tell him the news as soon as he comes back.

注：有時(shí),為了特意表達(dá)剛剛完成某事就如何如何,需要用現(xiàn)在完成時(shí).

如：I will go with you as soon as I have washed my face.

2、指緊接著發(fā)生的兩個(gè)短動(dòng)作,主從句都用一般過去時(shí)

如 He took out his English books as soon as he sat down

不過,我也見過從句和主句都用一般現(xiàn)在時(shí)的情況.

如：As soon as he finishes his classwork,he runs out of the class.他一做完課堂作業(yè),就跑出了教室.
