高考临近,小编为大家准备了些高考词汇及其用法和搭配,希望大家能从中获益!
用法一、起副词作用,其意为以防万一.
You had better carry some money in case.你最好带些钱,以防万一.
It may rain; you’d better take an umbrella in case.可能下雨你最好带把伞,以防万一.
用法二、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.
