阅读理解。

      Last summer vacation, I volunteered to work at a vet's (兽医诊所). There I saw a lot of dogs. Minnie

was the funniest-looking dog I'd ever seen. Short thin curly hair covered her sausage-shaped (香肠形) body.

Her eyes always seemed surprised. And her tail looked like a rat's tail. 

     She was brought to the vet because her owners didn't want her any more. I thought Minnie had a sweet

personality, though. "No one should judge her by her looks," I thought. Finally, I advertised Minnie in the local

paper. "Funny-looking dog, well-behaved, needs a loving family."

     When a boy called, I warned him that Minnie was strange-looking. The boy on the phone told me that his

grandfather's sixteen-year-old dog had just died. They wanted Minnie no matter what. I gave Minnie a good

bath. Then we waited for them to arrive. At last, an old car pulled up in front of the vet's. Two kids raced to

the door. They picked Minnie up and rushed her out to their grandfather, who was waiting in the car. I hurried

behind them to see his reaction to Minnie. Inside the car, the grandfather held Minnie in his arms and stroked

her soft hair. She licked (舔) his face. Her tail wagged (摇摆) around so quickly that it looked like it might fly

off her body.

     "She's perfect!"the old man said happily.

      I was thankful that Minnie had found a good home.

      Suddenly, I saw that the grandfather's eyes were a milky white colour-he was blind.
