“must have + 过去分词”表示对已发生事情的猜测。在英语中，must，may，can三个情态动词可用来表示对事情的猜测。Must意为“肯定”，语气很有把握；may意为“可能”、“也许”，语气把握性不大。两者常用在肯定句中。Can意为“肯定”、“也许”，常用在否定句或疑问句中。Must，may，can三者用于表示猜测时，其后面可跟三种不同的动词形式：1）跟动词原形表示对现在事情的猜测；
2）跟be doing表示对正在发生事情的猜测；3）跟have done表示对已经发生的事情的猜测。例如：
Helen is Lucy’s good friend. She must know Lucy’s e-mail.海伦是露茜的好朋友。她肯定知道露茜的电子邮件。
