筑坝“小天才”河狸
Beavers (河狸) are cute animals. They are brown. They have big teeth and a flat tail. Beavers are good at building dams (筑坝). They use wood and stones to build dams in rivers. The dams are their homes. They live in the dams with their families. I think beavers are very smart. I like them a lot!
