March 12th is Tree Planting Day. This year our school bought enough trees before that day . On that day , we didn't had classes . The teachers and our classmates planted trees around our school. We began to planted trees as soon as we got to school . some students dug the holes . Some students put the trees into the holes. Some students put the earth back to the holes. Then we pushed the earth hard with our feet . At last we watered the trees as much as possible. From then on we looked after the trees carefully and the trees grew very well . It made our shcool more beautiful .And How happy we are !
