具体如下：
Recently, I saw garbage bags of students eating snacks everywhere on the ground inside and outside the campus. When the wind blows, they fly everywhere. All kinds of smells mix in the air. I really can't stand it.
最近，我看见校园内外地上到处都是同学们吃完零食的垃圾袋，风一吹，四处乱飞，各种气味在空气里混合，我真的有点儿受不了了。
One day, on my way to school, I saw a senior male classmate who bought a big bag of snacks in the convenience store and ate while walking on the road. After a while, he finished eating and threw the garbage into a very conspicuous place. I thought to myself: this big brother is too uneducated. I have to persuade him.
有一天，我走在放学的路上，看见一位高年级的男同学，在便利店买了一大袋子零食，在路上走边吃。不一会儿，他吃完了，就把垃圾随手扔到了非常显眼的地方。我心想：这个大哥哥太没有修养了，我得去劝劝他。
So I went up to him and said, "big brother, it's wrong for you to litter. You should..." before I finished, the big brother replied to me: "little fart, when's your turn to talk about me! Mind your own business! "
于是，我上前对他说：“大哥哥，你乱扔垃圾是不对的，你应该……”话还没说完，大哥哥就回了我一句：“小屁孩儿，什么时候轮到你说我啦！少管闲事！”
I was so angry that I scolded him with a tiger's face: "people say you're for your own good. You're hopeless! The campus environment is everyone's, everyone should love it! If everyone were like you, this beautiful campus would have been destroyed. "
我一下子被气坏了，就虎着脸训了他一顿：“别人说你是为了你好，你真是无可救药！校园环境是大家的，每个人都应该爱护！如果大家都像你一样，这美丽的校园早就被破坏了。”
"I won't listen! Lala, see what you can do to me. " He made faces and I was so angry. So I ignored him, glanced at him, turned around and left.
“我就不听！啦啦啦，看你能把我怎么样。”他做着鬼脸，气得我真是七窍生烟。于是，我也不理他了，撇了他一眼，转过身就走了。
This is my personal experience. I feel very helpless. I hope you will not litter inside and outside the campus in the future, so as to create a beautiful environment for our study and life. Let's start from now on, from small things, and make our campus more beautiful.
这就是我的亲身经历，我感到很无奈。希望大家以后不要在校园内外乱扔垃圾，为我们的学习和生活创造一个美好的环境。让我们从现在做起，从小事做起，把我们的校园变得更加美丽。
