School rules are very important. There are many rules in our school. For example, we should wear our school uniform at school and we should go to school on time. We are required to keep the classroom clean and tidy. We can't eat, drink or sleep in class. We must do our homework too. I think these rules are good for our study and school life. Some students don't like wearing school uniform all the time because it's boring. It's ok with me.
