1．表示对过去事情的推测或估计。
(1)情态动词must＋have done只用于肯定句中，表示对过去发生的事情或状态进行的肯定推测，意为“过去一定做过某事”。
It must have rained last night, for the road is wet.
昨天晚上一定是下雨了，因为路还湿着。
You must have seen the film the Gold Rush. 语 法
精 讲情态动词+have done你肯定看过电影《淘金热》。
注意：表过去“不可能做了”不能用mustn't have done。
(2)can't have done /couldn't have done表示对过去发生的事情或状态的否定的推测，意为“过去不可能做过，肯定没做过”。
My sister met him at the theatre last night, so he couldn't have attended your lecture.
我姐姐昨天晚上在电影院遇见他了，所以他肯定没参加你的演讲。 语 法
精 讲 (3)can/could have done用于疑问句中表示对过去发生的事情或状态的不太有把握的推测，常表示“过去可能做过吗？”。
I can't find Tom anywhere in the office building.Where can he have gone?
我在办公楼任何地方都找不到汤姆。他有可能去了哪里了呢？
注意：表推测的情态动词只有can/could常用于疑问句中。 语 法
精 讲 语 法
精 讲 (4)may/might＋have done表示对已发生的动作或存在的状态进行不肯定的推测，表示“过去可能做过某事”， might语气比may稍弱。
You might have read about it in the papers.
你可能在报上已经看过这个消息了。
She didn't get there in time.She may have missed the bus.
她没能及时到达那儿。她可能没赶上公共汽车。2．表示对过去所发生事情的一种遗憾或责备的语气。
(1)should/ought to＋have done 表示“过去本该做而没做”。其否定形式为：shouldn't/oughtn't to＋have done “过去不该做的事却做了”。
I should have studied hard, but it was too late.
我本该努力学习的，但为时太晚了。

You needn't have watered the flowers, for it is going to rain.
你本不必浇花，因为天快要下雨了。 语 法
精 讲 例1Had they known what was coming next，they______________second thoughts. 语 法
精 讲例题剖析might have had 考查虚拟语气中的情态动词。本句是一个倒装句，可还原为：if they had known what was coming next，they...second thought。根据had known提示，可知是与过去事实相反，因此虚拟语气主句中应该用would/might＋have done。 例2Jack described his father，who_______________a brave boy many years ago，as a strong－willed man. 语 法
精 讲must have been 考查情态动词推测用法。 句意为 “杰克把他的父亲描述为一个意志坚强的人， 他的父亲多年前肯定是一个勇敢的男孩子”。用must have been表示对过去事情的肯定推测。 例3—Sorry，Professor Smith.I didn't finish the assignment yesterday.
—Oh，you ______have done it as yesterday was the deadline. 语 法
精 讲should 根据句意，此处表示和过去事实相反的情况，应该用 should＋have done，表示“本来应该做而未做”。
