Jason Queally is one of the fastest men in the world on a bicycle.Jason’s human-powered(人力的)machine , with its two wheels , is a kind of bicycle.
Every year , a very important human-powered bicycle race is held in Nevada,USA . The distance of the race is only 200 meters . Jason Queally’s fastest speed for the race was 103.5 kilometers an hour .
At 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 of his bike . When he tried to slow down ,his bike 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(碰撞)could be very serious . Jason was frightened , but he managed to stop the bike safely . He would repair his bicycle and try again to be the world’s fastest man on a bike next time .
Maybe you’re surprised that these bikes go so quickly , but is it useful ? It could be . Cars are becoming more and more popular , and they are very safe , comfonable 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(交通工具)that might be useful for daily travel !
