题型:不详难度:来源:
—She looks very happy.She_______have passed the exam.
—I guess so.It’s not difficult after all.
A.shouldB.couldC.mustD.might

答案
C
解析
“must have+动词-ed形式”表示“一定做了某事”,根据所提供的情景“She looks very happy.”可判断出她一定通过了考试。“should have+动词-ed形式”表示“本来应该做某事,而没有做”,常用于表示责备。“could have+动词-ed形式”在肯定句型中,往往用作委婉地批评,表示本应该做什么,而没做,有时也用作猜测。“might have+动词-ed形式”表示推测过去做过某事,“也许”发生了。
