On a sunny morning, Xiao Ming and Xiao Hong finished breakfast and hurried to school.

As they walked, a smell hit their nostrils. Suddenly, Xiaohong stopped next to a trash can and frowned. "Who is so uncivilized? They don't throw garbage into the trash can, but throw it on the ground. Alas!" Xiao Hong said angrily. Xiao Ming looked at his watch and said anxiously: "Let's go, it's too late!" Xiao Hong said loudly to Xiao Ming: "If we don't put these garbage into the trash can, it will affect our living environment!" After that, He bent down and picked up the garbage into the trash can. Xiao Ming was as anxious as an ant on a hot pot, but when he heard what Xiao Hong said, it still made sense. He put down his schoolbag, took out a pen and a piece of paper, and wrote six big words on the paper: "Civilization - only one step away." Then he stuck the piece of paper firmly on the trash can. . After Xiao Hong finished picking up, she wiped her hands and gave a thumbs up to Xiao Ming: "You are awesome!" The sun shone warmly, and Xiao Ming and Xiao Hong hurried to school again.

The city is our home, we must protect it and not let it be destroyed.
