As students,it's very important for us to know what we should do and what we should not do.
at school.we should be pollite to the teachers and classmates.doing homework everyday and go to after-school activities on time.speak polite words in public,be friendly to everyone.for example,on a bus,there is a empty seat.if an old people standing there,let them sit first,dont litter things about everywhere,put rubbish in the bin instead of drop it.we try to do everything we can to protect the enviroment.If we do so,I'm sure we will be polite students
