Every time I walk into this spotless classroom, I see a messy classroom. Drinking milk in art class is the dirtiest. When drinking milk, students pick up the milk, pull out the straw and tear off the straw skin. Insert the straw into the milk carton, drink it with relish, and throw out the straw skin. Transparent straw skin flutters in the air, like a small transparent leaf swaying in the air with the wind. Some students pick up empty boxes, open the lid of the trash can and play the game of scoring goals with empty boxes. Some students are playing fly ball in the air. They threw empty boxes on the ceiling. When they want to land, they kick it with their left foot. Because the box is light, it is not easy to master the direction, and finally it falls on the head of the classmate. Some students put the unfinished milk box on the ground and stomped on it, only to see milk spilled everywhere, on the desk, on the floor and on their classmates. It's really disgusting.
In art class, it's even worse. Once, the teacher had something on the way and said to us when he went out, "Please be quiet." Say that finish, the teacher left. Soon after the teacher left, most students became noisy. There are 42 people in our class. One third of the students took out all the "garbage stored for many years" in the drawer. In order not to let teachers know that they don't like hygiene, they kick rubbish in all directions. After a while, I saw that the ground was full of rubbish, like fallen leaves in autumn, which rustled when I stepped on it. Other students crumpled up the paper and threw it around. The whole classroom is in a mess.
Environmental sanitation is maintained by everyone. I hope students don't litter. If people don't litter and plant trees, the earth will be as beautiful as before, and disasters will not happen again and again.
If everyone doesn't spit and litter, I think our earth will be more beautiful.
