(单选题)
You ______ your stay in Dali, didn’t you? You look amazingly different.
A.must have enjoyed
B.should have enjoyed
C.can have enjoyed
D.enjoyed
参考答案:A
参考解析:
考查情态动词+have done的结构。句意:你一定在大理过得很愉快,对吗?你看起来非常不同。must have done意为“肯定……”,表示对过去的肯定推测;should have done意为“应该……”,表示对过去的虚拟;can have done和动词过去式不用于表示推测。根据didn’t和后文的“You look amazingly different”可知,题干表示对过去的肯定推测。故选A。
