What energy-saving poems tell me to use in class?

Shen Li, a poet in the Tang Dynasty, hoed the ground at noon and sweat dripped down the soil. But every grain of food is hard. Water, you are the blood of the earth. Without you, there would be no life on the earth. Water, you are the lifeblood of the earth. Without you, there would be no human beings on the earth. Everyone must save water. Water, water, water, there will be life on earth. Electricity is the life of the machine, my life, everyone's life and society's life. Without electricity, water cannot be boiled. Without electricity, the machine can't run. We can't live without electricity, but we should cherish it! How amazing you are, you are another life for us. If there is no electricity in the world, the world will be dark. Electric lights give us light, television gives us entertainment, and computers give us knowledge. Electricity is so great that we should all save electricity!
