Penguins look so funny when they waddle (摇摇晃晃地行走). I’m interested in learning more about penguins. Some penguins live in Antarctica (南极洲) and feed on (以……为食) fish, shrimp and squids. They can’t fly, but they can swim fast. There are many different kinds of penguins in the world, such as emperor penguins and blue penguins.
