阅读下面的短文，回答问题。

Jason Queally is one of the fastest men in the world on a bicycle．But do you really call the thing in the picture a bicycle？Well，yes．Jason's human-powered machine，with its two wheels，is of course，a bicycle．

Every year，a very important human-powered bicycle race is held in Nevada，USA．The speed of the bike is measured for only 200 metres，but players take more than a kilometre to get their bikes going fast．Jason Queally's fastest speed for the 200-metre race was 103.5 kilometres an hour．

At this year's race，Jason failed to reach the finishing line．He was speeding along at about seventy kilometres an hour when he began to lose control 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 kilometres an hour，a crash 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 becoming more and more popular，and they are very safe，comfortable 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 human-powered vehicles that might be useful for daily travel．

参考译文

贾森·奎利是世界上骑自行车最快的人之一。但你真的能把图片中的这样东西叫做自行车吗？是的，贾森的这辆有两个轮子的人力机械当然是自行车。

美国的内华达州每年都要举办一项非常重要的人力自行车赛。自行车的测速距离只有200米，但骑手们要骑一公里多的路程来加速。贾森·奎利在这段距离上取得的最快速度是103.5公里每小时。

在今年的比赛中，贾森没有冲到终点线。他在加速到70公里每小时时，自行车开始失控。当他想减速时，车开始冒烟。很快，自行车内部充满了浓烟。他看不见，也无法呼吸。如果在70公里每小时的速度下发生碰撞，后果是很严重的。贾森很害怕，但他还是设法把车安全地停了下来。他将修理这辆车，下次再试，以争取成为世界上骑自行车最快的人。贾森，希望你下次走运。

也许你会觉得，这些自行车跑得这么快有用吗？或许有用。汽车正变得越来越普及，它们既安全、舒适，也容易驾驶，但它们对城市的空气造成污染。科学家和工程师正在研究这些跑得很快的赛车，以使它们更适于日常出行。
