"Well, we're in our new house. Let's get a new pet." Mrs. Brown said to her husband.
"That sounds a good idea," he answered. "Maybe we can see the ads (广告) in the newspaper."
"Let's go to the
animal shelter. Many pets there need homes. Tomorrow is Saturday, we can go together," 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."
After they talked for a while, the Browns planned to get a small dog. It wouldn't need a big house or a big
yard (院子). A small dog would bark and warn (警告) them if someone tried to come into their house. After
Mr. Snow gave the Browns a book on pet care, they chose one and wanted to take her home right away. But the
animal doctor needed to check her. So Mr. Snow told them to come again on Sunday. On Sunday afternoon the
Browns went to the animal shelter. The animal doctor said, "Shadow has had all of the shots (预防针). She will
be healthy." The Browns thanked the doctor and took Shadow home.
