状语从句的时态特点一般情况下，时间和条件状语从句的谓语动词一般用“一般现在时”表示“一般将来时”，用“现在完成时”表示“将来完成时”。例如：
I will call you as soon as I arrive in Beijing. 我到北京就将给你打电话。
(这是由as soon as引导的时间状语从句，从句中的谓语动词arrive是一般现在时，表示一般将来时，绝不可用will arrive)
As soon as I have finished this work, I will have gone home. 我一完成此工作，就回家。
(从句中的谓语动词用现在完成时have finished，表示将来完成时,绝不可用will have finished)
If he comes back, please let me know.如果他回来了，请通知我。
(从句中的谓语动词用comes back,表示一般将来时，绝不可用will come back)
