if 与unless 引导条件状语从句时都遵循”主将从现“原则，从句的一般将来时用一般现在时代替，即主句用一般将来时/祈使句，从句用一般现在时。有时它们可互换。如：
1.If you work hard, you will get good results .
如果你努力学习，你会取得好成绩。
=You won't get good results unless you work hard .
你不会取得好成绩，除非你努力学习。
2. You will miss the early bus if you don't get up early .
如果你不早点起床你会错过早班车。
If如果 后接现在时，另外半句用将来时If you go there , I will go with you Unless除非 后接现在是，另外半句用将来时You will fail unless you work harder.
依主句而定，主句用过去时，从句也用过去时；主句用一般将来时，从句用一般现在时。
