Our school isn’t too big, but very beautifully. In the spring, it is cover with green trees and many bird are singing in the trees. So all the students likes our school very much. Our school has 63 classes dividing into 3 grades. In our school, there was a big football field. We have P.E. classes on there and we often do sports after school. We also have four teaching buildings, that are so tall, and we study in them. However, all of our teachers work very hard without any complaint(抱怨), especially our English teacher, Mr. Wei. So we love our teachers and each of us makes up our mind study hard.
