Question

Andrew Ritchie, inventor of the Brompton folding bicycle, once said that the perfect portable bike would be “like a magic carpet…You could fold it up and put it into your pocket or handbag”. Then he paused: “But you’ll always be limited by the size of the wheels. And so far no one has invented a folding wheel.”
It was a rare — indeed unique — occasion when I was able to put Ritchie right. A 19th-century inventor, William Henry James Grout, did in fact design a folding wheel. His bike, predictably named the Grout Portable, had a frame that split into two and a larger wheel that could be separated into four pieces. All the bits fitted into Grout’s Wonderful Bag, a leather case.
Grout’s aim: to solve the problems of carrying a bike on a train. Now doesn’t that sound familiar? Grout intended to find a way of making a bike small enough for train travel: his bike was a huge beast. And importantly, the design of early bicycles gave him an advantage: in Grout’s day, tyres were solid, which made the business of splitting a wheel into four separate parts relatively simple. You couldn’t do the same with a wheel fitted with a one-piece inflated （充氣的） tyre.
So, in a 21st-century context, is the idea of the folding wheel dead? It is not. A British design engineer, Duncan Fitzsimons, has developed a wheel that can be squashed into something like a slender ellipse （橢圓）. Throughout, the tyre remains inflated.
Will the young Fitzsimons’s folding wheel make it into production? I haven’t the foggiest idea. But his inventiveness shows two things. First, people have been saying for more than a century that bike design has reached its limit, except for gradual advances. It’s as silly a concept now as it was 100 years ago: there’s plenty still to go for. Second, it is in the field of folding bikes that we are seeing the most interesting inventions. You can buy a folding bike for less than £1,000 that can be knocked down so small that it can be carried on a plane — minus wheels, of course — as hand baggage.
Folding wheels would make all manner of things possible. Have we yet got the magic carpet of Andrew Ritchie’s imagination? No. But it’s progress.

A．were difficult to separate

B．could be split into 6 pieces

C．were fitted with solid tyres

D．were hard to carry on a train

【小題3】We can learn from the text that Fitzsimons’s invention        .

A．kept the tyre as a whole piece

B．was made into production soon

C．left little room for improvement

D．changed our views on bag design

【小題4】Which of the following would be the best title for the text?

A．Three folding bike inventors

B．The making of a folding bike

C．Progress in folding bike design

D．Ways of separating a bike wheel

Answer 1

【小題1】A
【小題2】C
【小題3】A
【小題4】C

解析【小題1】邏輯推理題。從文章第一段Andrew Ritchie, inventor of the Brompton folding bicycle, once said that the perfect portable bike would be “like a magic carpet…ou could fold it up and put it into your pocket or handbag”.
【小題2】細節判斷題。從文in Grout’s day, tyres were solid, 可知。
【小題3】細節判斷題。從第四段最后一句話Duncan Fitzsimons, has developed a wheel that can be squashed into something like a slender ellipse （橢圓）. Throughout, the tyre remains inflated.可知。
【小題4】邏輯判斷題。從整篇文章中可以看出是對便攜式是自行車的設計的改進。
