Good afternoon,everyone
We are studying in this school,It's our duty to keep it clean and tidy.It's not good to spit in public places,such as in the library,in the classroom, on the playground. 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.I'm sure our school will be more beautiful.
That's all.Thank you.
