题目
题型:不详难度:来源:
David, you _____play with the valuable bottle; you_______ break it.
A.won’t; can’t B.mustn’t; may
C.shouldn’t; must D.can’t; shouldn’t

答案
B
解析

试题分析:句意:大卫,你最好不要玩这个贵重的瓶子,你可能会打破它。mustn’t表示禁止,不允许;may表示可能,can’t表示不可能,shouldn’t表示不应该,故选B
点评:情态动词用法较多,无人称和数的变化, 情态动词后面跟的动词需用原形,否定式构成是在情态动词后面加 "not"。 must必须肯定的推测,can’t表否定的推测。个别情态动词有现在式和过去式两种形式, 过去式用来表达更加客气, 委婉的语气, 时态性不强, 可用于过去,现在或将来。高中阶段必须对它们的用法有个基本的了解,题目不难,掌握了平时出现的题目即可答出。
