假定你班今天下午要开一次以Keep Our School Clean为主题的英语班会，请以班长的身份准备一篇70词左右的发言稿。
提示：不随地吐痰，不乱扔垃圾，不在墙壁上乱涂乱画，每天保持教室内外清洁等(不要逐句翻译)
Good afternoon, everyone!
We're studying in this school. It's our duty to keep it clean and tidy. It's not polite to spit in public places, such as in the library, in the classroom. We should neither draw pictures on the walls nor throw any litter onto the ground. I think we must make it a rule to do some cleaning every day. If everyone tries his best to do something useful for our school will be more beautiful.
That's all. Thank you!
