单选题The next decade could see commuters speeding to work at about 300 miles per hour aboard magnetic levitation vehicles, according to a report by Argonne National Laboratories. But before "maglev" vehicles can become commercial successes, the report says, people need to stop thinking of them as high-speed trains. Instead, consider them low-flying aircraft.
