1 . The worst tourist in the world may be Mr. Smith in San Francisco.

Once he flew to his hometown in Italy from America to visit his family. The plane made a one-hour stop to get something at the airport in New York. But Mr. Smith mistook New York for Rome, so he got off the plane.

When nobody was there to meet him, Mr. Smith thought perhaps they were held up by heavy traffic. While looking for his address, Mr. Smith found that the old “Rome” had changed a lot. Many old buildings were replaced by high modern ones. He also found that many people spoke English instead of Italian.

Mr. Smith knew very little English, so he asked a policeman for help. Luckily, the policeman was also born in Italy and answered him in the same language.

After six-hour traveling around on a bus, the driver had to take him to a police station. Mr. Smith didn’t believe he was still in New York when he was told so. In order to catch a plane back to San Francisco, a policeman drove very fast with siren(警笛) on to sent Mr. Smith to the airport. “Look”, said Smith to himself, “I know I’m in Italy. That’s how the policeman drives.”
