Teachers often teach us not to throw scraps of paper, but many students just can't remember them. The classroom is full of peels and scraps of paper, which is very dirty. Therefore, we are often criticized.

One morning, I came to the classroom with my schoolbag on my back. Seeing that many students are surrounded by the health corner of the classroom, I can't wait to watch the fun. It turns out that there is a trash can in the sanitation corner, and all the students are talking about it. I took a closer look and found a note on the trash can! The clever Ruan Dezhi rushed to read aloud: "Little friend, I am so hungry, please leave me the waste!" " "How interesting! Who brought it? You look at me, I look at you, I can't guess.

No matter who brought it, the trash can still works. The students picked up scraps of paper from the ground, took waste paper out of their pockets and drawers and threw it into the dustbin. Some students threw it over and said, "Let's fill you!"

Once in an art class, the teacher asked us to draw. I accidentally drew the wrong place, so I tore off the paper, crumpled it up and threw it on the ground. At this moment, I suddenly remembered the note posted on the dustbin, and quickly picked up the paper ball and put it in the desk. After class, I threw the paper into the dustbin, as if I saw the dustbin nodding and smiling at me.
