as soon - as 引導從句可以換成什麼

as soon as引導的時間狀語從句的規則：若主句為一般將來時，從句常用一般現在時表將來若主句不是一般將來時，那麼從句的時態就要根據上下文來定。

1as soon as的用法

1、指未發生的動作，規律是：主句一般將來時，從句用一般現在時代替一般將來時

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

注：有時，為了特意表達剛剛完成某事就如何如何，需要用現在完成時.

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

2、指緊接着發生的兩個短動作，主從句都用一般過去時

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在時的情況.
