  • 17、“Joe, you are a very old dog,” said policeman Fred. “Today is your birthday again. I remember that you were 14 years old last year. But you are still the best police dog in the world!” “ARF! ARF!” barked Joe. “You are welcome,” said Fred. “Now let's get your birthday dinner. Show me where you want to eat.” Joe led Fred down the street. Good smells came from all the eating places. But Joe walked on. At last he stopped at a small place. He smelled around the door. Then he pushed the door open. “Is this where you want to eat?” asked Fred. But Joe did not bark an answer. He put his nose to the floor and ran across the room. Then he jumped on a man at a table! “Good boy, Joe!” said Fred. Joe and Fred have looked for the robber for ten years. “And now you have found him!” Joe and Fred took the robber to the police station. Then Fred said, “All right, Joe, you have done your work. Well done! Congratulations. Now do you want that birthday dinner?” “ARF!” barked Joe, “ARF! ARF!” “Let's go,” said Fred. “I'm hungry, too.”统考英语阅读理解
