As a student, our duty is to study hard instead of playing. Studying is important. So, we should have classes on weekends. Students in our school have classes every weekend. Every Saturday morning, we get up early and have a quick breakfast, then go to school. It is tired but we get a lot. We have more time to study. It is good for us to get good grades in the exam. As is known to all, a little learning is a dangerous things. My parents and classmate also agree that students should have classes on weekends and having classes on weekends is good for us. Well, I think so. Studying is good. But we should learn how to have a rest. O weekend, some student will play computer games for a long time or they don’t go to bed until 12 o’clock. These are bad for us. People always say, no play and all work makes Jack a dull boy. That’s ture. We should learn how to have a rest first. That will made us get good grades.
