After I came to Luoyang Normal University, I get in touch with more and more college students. I find a very serious problem about unhealthy habits of college students, which affects out regular college life.
Firstly, a large number of students stay up late everyday, but sometimes get up early. When they arrive at classroom, they feel very tired. Secondly, some college students become addicted to computer games and spend too much time on them. Thirdly, some college students are in love with their friends. When a college student tells his beloved that he will love her forever, it probably can’t be true. In the end, many college students have unhealthy eating habits. Sometimes, they go to classes without having breakfast, so they may have stomach diseases if this last long.
As college students, we should find out the reason why we have so many unhealthy habits. In senior middle school, we were too busy to relax ourselves, while we have full free time when we came to college, so we become lazier.

Recently, the problems of college students have been brought into focus especially their unhealthy habits.
The first part is about their life. Many of them often sleep so late that the next day they have no enough energy to study and often have a hurried breakfast for getting up late. The next part is about their entertainment. Many students especially boys are lost in computer games. They often spend too much time on it and forget to sleep, eat and study. There are also some bad habits in their eating. Many boys and girls smoke and drink a lot and eat too much junk food.
The unhealthy habits are due to the fact that they often have a lot of spare time and they don’t know how to make full use of it. Another reason is that they lose their aims and they don’t know what they want to do in the future.
