单选题 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'll tell you about some of them. Zip's 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." "We should
take it back." "We can't," said my sister. "I
know we can't," I said. "We don't know where Zip found it."
"Maybe little Tom is right," Mary said. "Maybe Zip is a keep dog!"
