The advance of science and technology makes people have more free time. Nowadays, we have 5-workday week. Therefore, our university and college students can have much more leisure time. Sports fans can play in the playground. Some students who are interested in social work can join many clubs. Of course, we also can get a part time job to gain some work experience.

　　 There is a growing concern over the students who don't put too much emphasis on study. Some students always idle away their time, playing cards, drinking, gambling. These problems are really serious. Taking into account all these factors, we can safely come to the conclusion that the students will waste more time if they don't make good use of it.

　　 As a student, busy as I am with my study, I also do many interesting things such as reading novels, writing articles at the two-day weekends. All work and no play makes Jack a dull boy. It's really ture.
