Question

Zipped into a bag, it looks like a large umbrella. Unfolded, it goes along the street like any other bicycle.

It's the "A-bike", the brainchild (腦力勞動的產(chǎn)物) of British inventor Sir Clive Sinclair, who made history in the 1970s by developing the world's first pocket calculator. He described his new invention as "the world's smallest, lightest foldable bicycle".

"My original thought was that if you could have a bicycle that was dramatically lighter and more firm than the ones that exist today, it would change the way in which bicycles are used,"said Sinclair.

The mini-bike, showed in Singapore last week and set to go on sale worldwide in 2005 at a price of nearly US$300, is built for riders as heavy as 112 kilograms and is height-adjustable（可調(diào)整高度的）. It takes about 20 seconds to fold or unfold.

Its wheels are a quarter the size of those on a regular bicycle, but Sinclair promises a smooth ride for most cyclists. "You require no extra energy to ride the A-bike and it can go up to 15 miles per hour (24 kilometers per hour)," he said. Constructed mainly of plastic, the 5.5-kilogram bicycle folds into a package of less than 0.03 cubic meters （立方米）.

Sinclair also invented the first pocket TV in 1984 and the futuristic C5 electric tricycle in 1985. He said he hoped the bicycle would attract common citizens, officials, campers or anyone needing transport for a short trip and he said the next step for the A-bike was to add an electric motor in a few years.

Answer 1

【答案】

1.D

2.A

3.A

4.A

5.B

【解析】

1.D。推理判斷題，可用邏輯推斷法來解。由原文第二節(jié) He described his new invention as "the world's smallest, lightest foldable bicycle."可以推出答案。

2.A。數(shù)據(jù)運算題，可用邏輯運算法來解。由原文第五節(jié)Its wheels are a quarter the size of those on a regular bicycle可知，傳統(tǒng)自行車車輪大小是這種新自行車車輪的四倍。

3.A。細節(jié)判斷題，可用直接就題找文法來解。原文第五節(jié)Constructed mainly of plastic, the 5.5-kilogram bicycle folds into a package of less than 0.03 cubic meters.體現(xiàn)答案。

4.A。標題判斷題，可用標題判斷三原則來解。認真閱讀分析原文不難發(fā)現(xiàn)，本文自始至終介紹一種即將上市的新型折疊式自行車的與眾不同之處，因此以World's smallest foldable bicycle arriving為題既具有高度的概括性、強烈的針對性，又因口吻激動、催人奮進而具有一定的醒目性。

5. B。細節(jié)判斷題，可用邏輯推斷法來解。原文最后一節(jié)...the next step for the A-bike was to add an electric motor in a few years. 體現(xiàn)答案。
