I'm Mary. This is my friend, Polly. Look! It is yellow and brown. It's fat. Its ears are small. Its eyes are big. Its tail is long. Polly likes fish and milk. It doesn't like fruit. Polly can hop and run. But it can't swim. It likes playing with a ball. I usually go to the park at the weekend(周末). Polly follows(跟随) me. I fly my kite in the park. Polly runs after me. What is Polly? Do you know? It's a cat.
