现在，年轻人熬夜是很常见的情况，有些人沉迷于电脑游戏，有些人和他们的朋友出去玩。缺乏睡眠不仅使他们工作效率低下，同时也影响了他们的健康。

The lack of sleep always happens among young people, and most of them expect to make up sleep on weekends, but even they do so, it still hurts their body, for the irregular lifestyle in most of the time. I used to staying up playing computer games or watching TV series at midnight. After a week, I found my skin became darker and there came some freckles. So I decided to give up stay up and kept enough sleep. A few days passed, my skin became better and I had the energy to study. 
年轻人们总是会缺乏睡眠，他们中的大多数人希望在周末弥补睡眠，但是即使他们这样做，还是伤害了自己的身体，因为大部分时间不规律的生活方式。我经常在午夜熬夜玩电脑游戏或看电视连续剧，一个星期后，我发现我的皮肤变得暗沉，还有一些雀斑。所以我决定放弃熬夜，保持充足的睡眠。几天过去了，我的皮肤得到了改善，也有学习的精力。

Enough sleep can also make us stay young. Look at those people who look young in an old age. The secret is to keep healthy lifestyle and taking enough sleep is one of the important ways. Don’t think you are young and have the energy to stay up, some day, you have to pay for it.
