2019年mpa考试英语真题——虚拟语气392

{01}—I didn’t see her yesterday.
—Of course, you _____, because she had gone to a trip.
A.can’t B.may not have C.can’t have D.mustn’t have 解析： 从下文he had gone to a trip，可以断定你不可能见到他，用can’t，判断时态是指过去，用can’t have (seen)。
本题选C。
{02}Why _____ you always interrupt me?
A.must B.may C.can D.will 解析： 情态动词must可以表示“偏偏”的意思，是一种无可奈何的语气，句子意思是“你为何偏要打断我呢？”
本题选A。
{03}.--- Do you know Uncle Tom is crazy about gardening?
---Sure. He ____ his flowers in the garden now. A.may be watering B.must be watering C.could look after D.ought to watch 解析：考情态动词表示猜测的用法。在表示十分肯定的猜测时，要用must。从对话来判断，此刻Uncle Tom一定正在花园里种花呢。选项A是干扰项，要注意may在表示猜测时，仅能表示不是十分有把握的猜测。
本题选B。
