A Good Dog

My name is John. I'm a brown dog, I have a nice home. My master（主人）always（总是） plays with me. We like each other. I'm a good dog. Look at me. When my master tells（告诉） me to sit, I sit. If he tells me to catch a ball, I catch the ball. If he tells me to stay, I stay. But if I see a cat, I can't help myself（忍不住）. I don't listen to him, I don't like cats.
