“That sounds like a pretty good idea,” he answered. “Do you want to see the ads in the newspaper?”
“Let’s go to the animal shelter. Many pets there need homes. Since tomorrow is Saturday, we can both go,” she said.
The next morning the Browns met Mr. Snow at the animal shelter. “We want to be sure that the pets here go to good homes,” Mr. Snow said, “So I need to ask you some questions.”

On Sunday afternoon the Browns went to the animal shelter again. The animal doctor said, “Shadow has had all of her shots(预防针). She will be healthy.” The Browns thanked the doctor and took Shadow home.
