题目内容
---I saw Mr. Smith at Xianyang Airport this morning.
---You ____. He’s still on holiday in Hawaii.
| A．can’t | B．couldn’t have | C．mustn’t have | D．needn’t |
B
解析试题分析：句意：--今天早上我在咸阳机场看见斯密斯先生了。--你不可能看见他的，他正在夏威夷度假。因为是对过去的事情的推测，所以用情态动词+have done，排除AD，还有斯密斯先生在夏威夷所以是不可能出现在咸阳机场的，所以是否定推测，用couldn’t have done“过去一定不会做了”，must have done是肯定推测，“过去一定做了”，所以选B。
考点：考查情态动词的完成式
