Yesterday morning I got up at 6:00. Because we would go to plant trees on the hill. When we got there, we began to work right now. Some students dug pits, some carried trees, some planted them, and some watered the trees. All my classmates worked hard and happily. When we finished at five, we went home together. We all felt that we had done a meaningful thing.
