In order to be a good student, firstly your should respect your teachers and be polite to others.Secondly,you should always help the people who need your help and make them feel that you are willing th help them.Thirdly,you should obey the traffic rules.Go across the street when there is a zebra crossing.Stop when the traffic-light is red.And lastly,you must protect the environment.Don't throw rubbish everywhere.Don't walk on the grass,too.
In my opinion,I think it is not easy to do all of these above.But if you want to be a good student,start here,start now.
