Our School Rules
Rules are like the backbone of a school. They help us study and live in order. Here are some important rules in our school.
First, we must wear the school uniform from Monday to Friday. It’s a symbol of our school and makes us feel united. Second, we can’t be late for class. If we are late, we need to ask the teacher for permission before entering. Third, we must keep quiet in the library. No talking or running is allowed there, so that everyone can read in peace. Fourth, we shouldn’t litter or draw on the walls. Keeping the school clean is our responsibility.
I think these rules are necessary. They not only help us form good habits but also make our school a better place to study. Let’s all follow the rules and grow up happily.
