Civilization - just one step

The weather is really good today, the sky is clear, the birds are flying, and the air is exceptionally fresh.

Xiao Ming and Xiao Li walked on the way out of school and talked about the work of the book. They suddenly saw the rubbish bin next to it piled up with rubbish. Banana peel was still hanging on the edge of the bucket. Xiaoli said: "Xiao Ming, look, Now those brothers and sisters are throwing garbage at random, and the trash can is by their side, that is, they refuse to take more steps to throw the garbage into it. Xiao Ming, why don’t we put the garbage back into the trash can?” Xiao Ming used Turn your head around and learn to take a break and close your eyes. He thought of a way, saying: "Xiao Li, you put the garbage in the bucket first, I write something." "Good" Xiaoli replied.

Xiaoli put the garbage back into the bucket one by one. Xiao Ming is on the ground, holding a pen in his hand, and still has a big white paper to write things. After a while, Xiaoli took the garbage and looked at Xiaoming. He said, "Hey, Xiaoming, what are you writing, for a long time, haven't finished?" Xiao Ming said: "Okay." While using the double-sided tape in the bag to stick the white paper around, "beep" stuck to the trash can, and a piece of white paper was strikingly written with six words: civilization - only one step. Xiaoli smirked her hand and raised her thumbs. Qu Xiaoming said: "You are really a brain-loving classmate."
