At present, I am a senior student. After four years in college, I can be said to be a good student. I don't skip classes, fail classes or stay up late, but many of my classmates stay up late, even all night. At first, I wondered what they were doing so late. Don't they know they are sleepy? Until now, when I was in senior three, I didn't know what those classmates were doing.

Some students don't sleep at night, mainly playing games, especially boys, some online games and hand games. They are usually not alone, but several people together, playing games together in a dormitory until the early hours of the morning, and sometimes they will stay up all night when they are tall. For girls, many situations are reading novels and watching movies. That's my roommate. He often gets up at night to go to the toilet, watches his mobile phone at one or two in the morning, and he is still reading novels and online dramas.

Sometimes I can't sleep, or I can't sleep when I have something to do, but I have never stayed up until the wee hours like them. Many people will wonder, don't they sleep and get sleepy? Games, novels and TV plays are really so attractive. In fact, they are addicted. Moreover, most of these students don't go to class during the day, but sleep in the dormitory. They study during the day and play at night. In short, every day is dark.

Although I will graduate soon, I still think that college students should cherish their time and find opportunities to improve themselves and exercise themselves. They should not waste time in the virtual network world, and they should not waste their youth. And staying up late is really harmful to your health. For your own health, you should stay up as little as possible and have a healthy schedule.
