Little Tom down the street calls our dog "The keep dog". Zip is a sheep dog. But when Tom tries to say "Sheep", it comes out "keep". And in a way Tom is right. Zip is always bringing things home for us to keep! I? 11 tell you about some of them. Zip7s first present was a shoe. It was made of green silk. We didn't know how Zip found the shoe. But after a moment Mary,my big sister,told me the shoe had a strange smell. I nodded(点头) and held my nose. "What do you think it is?"“It smells like something for cleaning. I think someone tried to clean a spot (污点)off the shoe. Then he put it at the door to dry.""Along came Zip. And good-bye shoe!" I said. "We should take it back. We cant. " said my sister. "Maybe little Tom is right , " Mary said. "Maybe Zip is a keep dog!"
