Nature is wonderful. The beauty of the natural world lies in landscapes. Let’s walk close and listen to them.

I am the grassland. Colorful flowers grow here, and lovely animals like sheep and rabbits live happily on me. My plants take in carbon dioxide (二氧化碳) and produce fresh oxygen to clean the air. I store rainwater underground and feed nearby rivers. I am quiet and lively, a warm home for all living things.

I am a mountain. I stand high and I’m usually covered with rocks and earth. I work as a natural water tower—snow and rain on my peaks flow down to form rivers that offer drinking water. My thick forests slow down floods and protect the land from soil loss. I am strong and silent, watching the world for thousands of years.

I’m a desert. I am the Earth’s natural temperature keeper. I take in heat during the day and release (释放) it at night, keeping the temperature balanced. Besides, my plants store water in their leaves and give it to animals. Some animals feed on the leaves, and the water can keep them healthy.

After listening, we know that grasslands, mountains and deserts bring us beautiful sights and hope.
