As students, we need a harmonious campus to study in. Everyone should do sonwthing for it.
First, study hard and take part in after-school activities more. It can open up your eyes to the outside world.
Then, be friendly to each other and respect our teachers. We should be useful. Everyone has his or her advantages, whatever they are. Communicate more with your classmates and teachers.
Next, take good care of trees and flowers but don't throw the rubbish anywhere. Taking good care of our campus can give you a good environment to study in.
