We can find a lot of polite and impolite behavior every day．What should we do? I think we should get to school on time．We shouldn’t be late for school．We must wait in line and mustn’t cut in line．We should help pick up litter and shouldn’t drop litter everywhere．We mustn’t smoke or draw anything on the walls．We should be friendly to other’s and help them．We should not break in while other people are talking．We should keep our voice down in public places．And in fact，we should also take care not to cough or sneeze loudly in public．We should take care of trees，grass and flowers．When you borrow something，remember to return it．If we can do like this．I’m sure we’ll be polite students．
