This is my school. There are many trees and flowers in it. The teaching building is big and tall. There is a big playground in our school..It is very nice to have it . After 4:30 in the afternoon, many students come to the playground to play football and some students play table tennis in the table tennis room. There are 1,200 students in 30 classes in our school. The students all like to study. The teachers in our school are very good. They help the students to study and sometimes play with them .All the students like them, too. What may  teachers not do?
