We study in this school. It is our duty to keep clean and tidy. It's not good to spit in public places, such as in the library and in class. We shouldn't throw rubbish everywhere. Don't Scribble on the wall. They affect the appearance of our school. We should keep the classroom clean and tidy. We should always do some cleaning. If everyone tries their best to do something useful for our school, I believe our school will be more and more beautiful.
