“Well, we’re in our new house. Let’s get a new pet,” Mrs. Brown says to her husband. “That sounds like a very good idea,” he answers. “Do you want to see the ads （厂告）in the newspaper?” “Let’s go to the animal shelter. Many pets there need homes. Tomorrow is Saturday, so we can both go,” Mrs. Brown says.
The next morning, the Browns (Mr. Brown and Ms. Brown) meet Mr. Snow at the animal shelter. “We want to be sure that the pets here go to good homes,” Mr. Snow says, “So I need to ask you some questions.”
After they talk for a while, the Browns decide to get a small dog. It will not need a big house. A small dog will bark (吠) and warn (警告 ) them if someone tries to go into their house. After Mr. Snow gives the Browns a book on pet care, they choose one and want to take her home right away. But the animal doctor hasn’t checked her yet. So Mr. Snow tells them to come back on Sunday.
On Sunday afternoon the Browns go to the animal shelter. The animal doctor said, “Coco has got all of her shots  (预防针) . She is healthy.” The Browns thank the doctor and take Coco home.
