We are studying in this school. It is our duty to keep it clean and tidy. It is not good to spit in public places, such as in the library, in the class. We shouldn't leave rubbish here and there. Don't draw pictures on the wall, they influence the look of our school . We should keep the classroom clean and tidy. And we should do some cleaning often. If everyone tries his best to do something useful for our school, I'm sure our school will be more beautiful.
我们在这所学校学习。保持干净整洁是我们的责任。在公共场所随地吐痰是不好的，比如在图书馆、课堂上。我们不应该到处乱扔垃圾。不要在墙上画画，它们会影响我们学校的外观。我们应该保持教室干净整洁。我们应该经常打扫卫生。如果每个人都尽力为我们的学校做一些有益的事情，我相信我们的学校会更加美丽。
