What should you say when you see your classmates littering with scraps of paper? Watch your tone.

1, what you did was wrong. Peel scraps should be thrown into the trash can. How can you just throw it away? If everyone is like you, the classroom will be dirty. We should be civilized students, don't you think?

2. Don't throw peels and scraps of paper. Beautiful environment needs our love.

Please don't throw away the scraps of paper. Garbage can be put in the trash can, which will pollute our learning environment.
