How to behave well
Behaving well is the secret of getting on well with others.
As a student，I think it's very important to do everything on time and keep promises. Never lie to others or say dirty words. We should be polite to others and ready to help people in need. We'd better not talk loudly in public. Don't throw litter or spit about. And remember to obey traffic rules.
Finally，learn to work with others. We need good teamwork in our life.
