初三水平作文，求帮忙QAQ

my dear friends,
each of us has the duty to obey public rules. Let's say no to the bad behaviors.
There are some bad behaviors in our campus.like spitting here and there, playing with public facilities. so what should we do to build a civilized campus？Firstly, we should keep quiet in the library so that we won't bother others. what's more, we are supposed to return thebooks that we borrow in time. Secondly, we should wait in line when we want to buy something in the school's canteen, and try our best to eat up the food that we've bought. thinking about those poor people in Africa, they are struggling aganist hunger evry day because of the lack of food.Thirdly, we should concentrate on what the teacher is saying on class . Don't quarrel and fight noisily after class.
I am convinced that if everybody follows my advice, our campus will become wonderful!
望采纳!thank you!have a nice day!
