【题目】He _____ his stay in France, didn't he? He looks amazingly different.
A.will have enjoyedB.should have enjoyed
C.can have enjoyedD.must have enjoyed
在线课程【答案】D
【解析】
考查情态动词+have done。句意：他在法国一定过得很愉快，是吗?他看起来很不一样。must have done一定做某事。表示对过去事情的较有把握的推测。由“ He looks amazingly different.”可知，他在法国一定过得很愉快。所以这是对过去事情的较有把握的推测。故选D项。
