参考范文： The animal is a beaver
I think beaver is my favourite animal. It is cutting trees and building and mud. What is special about it is that it can change the environment to create a safe home. Its teeth are very strong and never stop growing.
I think beavers are true "nature's engineers". They are not only clever but also very important to the ecosystem. They create ponds where many other animals can live. That's amazing!
