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 he comes, let me know. 如果他来的话,告诉我一声。
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。
