单选题{{B}}Passage One{{/B}} When a conductor in Spain asked to see her train ticket, Janet Loops, an exercise instructor from Palo Alto, Calif., reached for her purse-and discovered her wallet was gone. She had no ticket, passport, credit cards, traveler's checks, cash. It took nearly a week to get a new passport and traveler's checks. Her trip was almost ruined. To guard against such disasters, especially, overseas, some experts suggest carrying your money and documents in a small, flat pouch around your neck and tucked under your clothing. A fanny pack can be used if carried in front, but be alert-it can be cut off. Other possible ways to foil(阻挠) pickpockets: Wrap rubber bands around a wallet to make it harder to lift from a pocket. Have zippers sewn into your blazer pockets. The key is to stay alert and "pack your common sense," says Alfred Boza, a Miami Beach police detective. Know, for instance, that thieves could be watching for you to leave' your bags unattended briefly at airport security checkpoints. If you're driving in unfamiliar places, keep as little as possible in your car's passenger area, where "smash and grab" thieves can get it. That means hiding luggage in the trunk and leaving nothing of value inside the passenger area when the car is parked. Also never leave maps-the mark of a tourist-visible. "Know where you're going before you get there," Boza says. "When shopping, leave your most expensive purchase for last." Ask at your hotel what parts of the city are dangerous, and avoid them. Before leaving his hotel room, Robin Myers, a computer researcher in Cupertino, Calif. , puts cameras and other articles too large for the hotel safe into luggage with combination locks. Wherever you are - in case of an emergency - have a phone credit card and know how to use it. The card will enable you to call an 800 number for help, sparing you the need for coins or collect calls.
