D D选项must have done表示的是对过去的一种肯定猜测. 题目中说“我很累,让我稍微休息一会”然后另一个人说“今天是周一,你周末一定熬夜了” stay up是熬夜的意思

D 你必须在周末休息。星期一不能休息。表示拒绝，表示只有周末可以休息

D
must have done something 表示对过去的事情的推测。

must have done 表示对过去情况的肯定推测。

我很累了，请让我再休息一会吧。
今天是星期一呀，你一定是周末熬夜了吧。（stay up 词组，熬夜）

A,ought to 就等于should have to 是本应该的意思，完整的就是你本应该在周末的时候休息的
