【题目】Punishments would be severe, ranging from a few years in prison to the death penalty _______ a person be caught carrying drugs.
A.shouldB.wouldC.couldD.might
在线课程【答案】A
【解析】
考查虚拟语气。句意：如果发现有人携带毒品，将会受到严厉的惩罚，从几年的监禁到死刑不等。因为与将来事实相反，所以从句用if +主语 + should + do。此处为省略if的虚拟语气的倒装，从句should a person be caught carrying drugs = if a person should be caught carrying drugs。故选A。
