Based on what i have surveyed,i found that most students have bad habit such as sleeping late,consuming a lot and addiction to the computer games.Because of the action,students may feel tired in class.The students may waste the time that the others spend on studyingto play computer game, which will make them far behing others in study.So long as they make a determind to chang their bad habit,there is still a chance to get health.
