In Case

凡是由lest(以免;免得),in case(以防)和 for fear that(生怕,唯恐)引导的目的状语从句中,用“should+动词原形 其谓语部分should可以省略。

1. in case作短语连词,能引导状语从句
其一:in case just in case引导目的状语从句作“以免以备以防”等解。如:

Please remind me of it again tomorrow in case I forget. 请你明天再提醒我一下,免得我忘记。
其二:in case接条件从句,意为“如果万一”。如:

注意: in case引出的条件从句表示的意义是"预防某种情况的出现";如果从句说的是一般的假设或条件,则要用if 。请比较:
I'll tell him about the matter if I meet him.  (不用in case)
Take an umbrella in case it rains.  (不用if )

I don't think it will rain, but I'll take an umbrella in case (it rains).
