3 阅读理解。 In 1977, Jack, an Italian-American who lived in San Francisco, flew from America to Italy to visit his relatives. On the way, the plane made a one-hour stop to refuel (加油) at the New York Airport. Thinking that he had arrived, Jack got out and spent three days in New York, believing he was in Rome. When his relatives were not there to meet him, Jack thought they had been caught in the heavy Roman traffic mentioned in their letters. While looking for their address, Jack could not help noticing that modernization had changed most, if not all, of the ancient city"s landmarks. He also noticed that many people spoke English with strong American accent. However, he just thought that Americans got everywhere. He also believed that so many street signs were written in English especially for the Americans. Jack spoke very little English himself so he asked a policeman in Italian the way to the bus station. As chance would have it, the policeman came from Italy and replied in the same language. After twelve hours traveling round on a bus, the driver handed him over to a second policeman. After brief argument with the policeman, Jack was very surprised to find that the Rome police had employed someone who did not speak his mother tongue. Jack did not believe he was told that he was in New York. In order to get on a plane to San Francisco, the policeman raced him to the airport in a police car with sirens (报警器) screaming.
