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? 题目- -I want to do something for my school
