2. 用于in case,有以下两个用法:
(1) 起副词作用,其意为“以防万一”。如:

(2) 起连词作用,用于引导条件状语从句和目的状语从句。
① 引导条件状语从句,意为“假使”“如果”。如:

In case they’re late, we can always sit in the bar. 要是他们来晚了,我们总可以在酒吧里坐一坐。
这类从句的谓语除通常使用陈述语气外,有时也可使用“(should+)动词原形”这样的虚拟语气。如:
I bought the car at once in case he changed [should change] his mind. 我马上买下那辆汽车,以免他变卦。
② 引导目的状语从句,意为“以防”“免得”。如:
Be quiet in case you wake the baby. 轻点儿,别吵醒婴儿。
Write the telephone number down in case you forget. 把电话号码写下来以免忘了。
3. 用于复合介词in case of,其意为“如果”“万一”“以防”。如:

In case of emergency, break the glass and press the button. 遇到紧急情况时,击碎玻璃罩并摁下按钮。
4. 用于in no case,意为“绝不”“无论如何不”。如:
In no case should you panic. 千万不要惊慌。

由于本身含有否定意义,所以当它置于句首时,其后要用倒装语序。如:
In no case should you give up. 你绝不能放弃。
