Well, yes. Jason’s humanpowered (人力的) machine, with its two wheels, is, of course, a bicycle.Every year, a very important humanpowered bicycle race is held in Nevada, USA. The speed of a bike is measured (測定) for only 200 metres, but players take more than a kilometer to get their bikes going fast. Jason Queally’s fastest speed for the 200metre race was kilometres an hour. As this year’s race, Jason failed to reach the finishing line. He was speeding along at about seventy kilometers an hour when he began to lose control (控制) of his bike. When he tried to slow down, it began to smoke. Soon the inside of his bike was filled with smoke. He couldn’t see, and he couldn’t breathe. At seventy kilometers an hour, a crash (撞擊) could be very serious. Jason was frightened, but he managed to stop the bike safely. He would repair his bicycle and try again another time to be the world’s fastest man on a bike. Better luck next time, Jason.Maybe you’re surprised that these bikes go so quickly, but is it useful? It could be. Cars are being more and more popular, and they are very safe, fortable and easy to drive, but they also pollute the air in our cities. Scientists and engineers are learning from fast racing bikes how to make humanpowered vehicles (車輛) that might be useful for daily travel.51.
