爱思英语编者按：早睡早起身体好！习大大都说了年轻人不要熬夜，该如何用英文劝说“夜猫子”早点休息别熬夜呢？

1. Don't stay up too late.

3. Why are you still up?

4. You should go to bed early.

6. Go to sleep.

7. Let's turn in early.

8. It's time to hit the sack.

该睡觉了。
 
注：to hit the sack只能指结束一天工作和学习后晚上去睡觉，午睡也不能用这个短语来表达。
 
9. You should keep early hours.

你应该早睡早起。
 
注：to keep early hours指养成早睡早起的习惯，偶尔早起不能使用这个短语。
 
另外，英文中形容早起者的短语有early bird, morning lark, early riser, morning type.
