1. must have slept,must have done,表示对过去的事情带有肯定语气的推断(根据有“没有听见对方来”这个事实).
2. can't be 表示不可能.表示推断的否定语气用can't,不能用mustn't
3. 这道题我觉得有不止一个答案,因为没有上下文,用might/must haven been都可以表示推断,不严格的口语中,could be和might be也未尝不可.
4. couldn't have.这里的can表示“能力”,couldn't表示“不能够”.
5. can't have escaped,对过去的推断的否定,表示他不肯能是从窗户逃出去的,因为窗户锁着.当然,如果表示能力的话,也可以用can’t,表示他现在逃不出去,因为窗户锁了.
如果不懂的话再问吧,情态动词的功能确实很麻烦.
