I want to make school clean.You may think it is very simple.But I don't think so.Our teacher said,"School is your home,you should keep it clean."But I have never done anything to make school clean.For example,I have never told my classmate to pick up rubbish after he threw it on the ground.I also threw the rubbish on the ground.So I want to make school clean so that everyone can forgive me.During this summer holiday,I will go to school to make school clean.Of course,I will do it with my classmates.We will make school clean every weekends next term as well.Now,do you think it is simple?
