You can't stay up late

不可以晚───You can't be late;睡───sleep

you should be sorry! Don't ever use my computer again! You can't do anything now, it's too late!───你应该道歉！再也不许用我的电脑了！现在你做什么都没有用了，已经太迟了！

Now you can't be late!───以后，你别迟到了。

If an activity on the critical path is a week late, you can't sit idly and allow the entire project to be a week late.───如果处在关键路径上的某个活动延期了一周，你可不能傻坐着眼看整个项目延期一周。

Well, you can't be late again.───你不能再迟到了。
