The classroom is a place where we play and learn so protecting it is something every student must know. So what do we need to do to keep it clean. First we need to clean, sweep the house, wipe the table cleaning table ..., next we should not throw garbage indiscriminately, but throw it in the trash. Put more trees in the classroom to keep it cool and educate your friends about how to stay clean in class. I criticize some of you for not knowing how to keep your classroom clean. The above actions can help us to protect the environment in which we study in a cool, hygienic way so that we always learn to keep a happy spirit in every class.
