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 s(此輪), 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 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 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.

你可能會驚訝於自行車已有兩百年的歷史了，但是沒有人知道是誰發明了這個如此受歡迎的兩個輪子的機器。
(31)早期的`自行車並不是現在的樣式。前輪比後輪大很多，而且沒有踏板。騎乘的人要靠兩腳蹬地才能使自行車前行。
(32)踏板出現於十九世紀四十年代。l897年，一位英國人想到用鏈條將踏板和後輪連線起來。十九世紀九十年代，齒輪被首次運用於自行車，這使得自行車能夠更輕鬆地行駛於上坡路段。
現在世界上大約有十億輛自行車。(33)它們的數量是汽車的兩倍多.在所有城市的街道上，自行車都不得不和汽車競爭，而且作為兩大主要交通方式，它們相處的並不融洽。例如2005年在倫敦，有超過300名騎自行車的人在交通事故中傷亡。
由於自行車比汽車更加環保安全，如今很多政府鼓勵人們騎自行車而不是開車。(34)在英國，自行車的數量正在增加。在過去的五年裡，英國騎自行車旅遊人的數量增加了50%。
然而，儘管每三個英國人裡就有一個人有自行車，但是他們使用的頻率不夠高。(35)騎自行車旅行的人只佔到英國旅行人數總量的2%。希望更多的人騎自車旅行。理由很明顯——自行車非常環保，騎自行車能保持身體健康，而且在很多情況下，騎自行車出行要比開汽車更便宜也更快捷。
31.F【精析】根據下文說自行車的前後輪大小不一，說明早期自行車與現代車的差別較大，此處應是早期自行車的樣式與現在不同。故F正確。
32.A【精析】下文提到有人用鏈條將後輪與“them”連線，可見之前應該是自行車上的部件，而且是複數的名詞。故A正確。
33.E【精析】上文說明自行車的數量較多，下文提到自行車和汽車進行比較。各選項中只有E將自行車的數量與汽車的數量進行了比較。故E正確。
34.B【精析】上文提及使用自行車的好處，下文提及騎自行車旅行數量的增加，只有B提到了數量增加。故B正確。
35.C【精析】根據上下文，此處內容應該為轉折，說明擁有自行車的人不在少數，但使用率不高。故C正確。
