人囗问题英语作文500字（精彩一篇）

Good afternoon, everyone!

We are studying in this school, and it is our duty to keep it clean and tidy. It’s not good to spit in public places, such as in the school library, in the classroom, etc. We should neither draw pictures on the walls nor throw rubbish here and there. I think we must make it a rule to do some cleaning every day. If everyone tried his best to do something useful for our school, I’m sure it will be more and more beautiful.

That’s all. Thank you.
