You might be surprised to know that bicycles have existed for about two hundred years, but no one is sure who first made this popular two-wheeled machine.
31 The front wheel was much bigger than the back one, and also there weren't any pedals (踏板), Riders had to move themselves forward by pushing their feet against the ground.
32 In 1879 an Englishman had the idea of connecting them to the back wheel with a chain.Gears(此轮), which made things much easier for those cycling uphill, first appeared in the 1890s.
There are now about one billion bicycles in the world.33 They have to compete with cars on the streets of all the world' s cities, and the two forms of transport don' t always mix well.In London in 2005, for example, over 300 cyclists were either killed or seriously hurt in accidents.
Because bicycles are much more environmentally friendly than cars, now many governments encourage people to ride rather than drive. 34 The number of yearly journeys made by bicycle in London has increased 50% over the last five years.
However, although one in three British people owns a bicycle, they still don't use them nearly as much as they could 35 .
It is hoped that more people will rely on bicycles to move around.The reasons are obvious--cycling helps to protect the environment, keep us fit, and it is often not only cheaper but also quicker than travelling by car in many cases.
A.Pedals fmally arrived in the 1840s.
B.Cycling is on the rise in the Unilted Kingdom.
C.Bicycles are used for only 2 % of journeys in the UK.
D.The first person who made a bicycle was an Englishman.
E.The number of bicycles is twice more than that of cars.
F.The early models didn' t look much like the bicycles of today.
G.Cycling helps improve people's health.
第二节补全文章参考译文
你可能会惊讶于自行车已有两百年的历史了，但是没有人知道是谁发明了这个如此受欢迎的两个轮子的机器。
(31)早期的自行车并不是现在的样式。前轮比后轮大很多，而且没有踏板。骑乘的人要靠两脚蹬地才能使自行车前行。
(32)踏板出现于十九世纪四十年代。l897年，一位英国人想到用链条将踏板和后轮连接起来。十九世纪九十年代，齿轮被首次运用于自行车，这使得自行车能够更轻松地行驶于上坡路段。
现在世界上大约有十亿辆自行车。(33)它们的数量是汽车的两倍多.在所有城市的街道上，自行车都不得不和汽车竞争，而且作为两大主要交通方式，它们相处的并不融洽。例如2005年在伦敦，有超过300名骑自行车的人在交通事故中伤亡。
由于自行车比汽车更加环保安全，如今很多政府鼓励人们骑自行车而不是开车。(34)在英国，自行车的数量正在增加。在过去的五年里，英国骑自行车旅游人的数量增加了50%。
然而，尽管每三个英国人里就有一个人有自行车，但是他们使用的频率不够高。(35)骑自行车旅行的人只占到英国旅行人数总量的2%。希望更多的人骑自车旅行。理由很明显——自行车非常环保，骑自行车能保持身体健康，而且在很多情况下，骑自行车出行要比开汽车更便宜也更快捷。
2016年3月全国英语等级考试二级真题答案(补全文章)
31.F【精析】根据下文说自行车的前后轮大小不一，说明早期自行车与现代车的差别较大，此处应是早期自行车的样式与现在不同。故F正确。
32.A【精析】下文提到有人用链条将后轮与“them”连接，可见之前应该是自行车上的部件，而且是复数的名词。故A正确。
33.E【精析】上文说明自行车的数量较多，下文提到自行车和汽车进行比较。各选项中只有E将自行车的数量与汽车的数量进行了比较。故E正确。
34.B【精析】上文提及使用自行车的好处，下文提及骑自行车旅行数量的增加，只有B提到了数量增加。故B正确。
35.C【精析】根据上下文，此处内容应该为转折，说明拥有自行车的人不在少数，但使用率不高。故C正确。
