As a studentit is very important for us to know what to do and what not to do.In schoolswe should go to school on time.Don't be late for class.In classwe should listen to the teacher carefully.Homework must be done.Don't copy other's homework.We should take an active part in sport and keep healthy.We should always be ready to help the people who are in trouble.When waiting for a buswe must stand in line and wait our turns.Don't push or jump the queue.In a buswe should not speak loudly or spit in public.Don't litter things about.It's our duty to protect the environment around us.
If every one does soI am sure he will be a polite student.
