Passage Five A young girl and a man were recently found murdered in a parked car in a Boston suburb. The police found no clue (线索) in the car. Then they found a witness who had seen a car pass by the murdered couple’s car. He said it was a 1950 or 1951 Chevrolet (雪佛莱牌汽车). Ordinarily, searching through the files for owners of elderly Chevies would have been an impossibly difficult task because there were two and a half million such cars. In this case, however, the police had a powerful tool--the computer. The Boston Registry of Motor Vehicles programmed its computer to screen all 1950 and 1951 Chevrolets within a fifteen-mile radius (半径) of the suburb--the area in which the police believed the murderer was most likely to be found. Within minutes, the computer uncovered one thousand of the wanted cars. A few hours of careful hand screening turned up a 1950 Chevrolet owner who lived close to the scene of the crime and who had received many traffic tickets (交通罚款).
A. Crime--A Grave Problem in the West
