听力原文： The twenty-third Olympic Games were held in Los Angeles and, like every other Olympic Games, they represented a contest of mind, muscle, and athletic determination. The use of high technology, however, showed increasing significance in the staging of the event and helped set an example for staging future events.

Unlike the Olympics of the past, the Olympics are not just a race for gold anymore. They have also become a race for computer technology. Playing the massive event, as any host can tell you, requires a technology plan and organization that brings hundreds of countries together. In the twenty-third Games, for example, computers were used to keep track of schedules, accounts, transportation, and ticketing for more than 43,000 Olympic employees and volunteers. This was not an easy task.

A sophisticated electronic message system, moreover, helped keep the 12,000 or so journalists up-to-date on results. Due to this system, they were able to know about and broadcast to the world the judges' final decisions usually within a minute's time. This message system also allowed traffic controllers to convey traffic reports more efficiently, so that the usually confused Los Angeles highways became easy to navigate. Computers and other high-tech tools were also used to train American athletes by analyzing and evaluating performances. This- computer marvelously assisted the athletes in identifying weaknesses and suggesting ways to improve.
