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 (脑力劳动的产物) 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（可调整高度的）. 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

DAAAB
1.D。推理判断题，可用逻辑推断法来解。由原文第二节 He described his new invention as "the world's smallest, lightest foldable bicycle."可以推出答案。
2.A。数据运算题，可用逻辑运算法来解。由原文第五节Its wheels are a quarter the size of those on a regular bicycle可知，传统自行车车轮大小是这种新自行车车轮的四倍。
3.A。细节判断题，可用直接就题找文法来解。原文第五节Constructed mainly of plastic, the 5.5-kilogram bicycle folds into a package of less than 0.03 cubic meters.体现答案。
4.A。标题判断题，可用标题判断三原则来解。认真阅读分析原文不难发现，本文自始至终介绍一种即将上市的新型折叠式自行车的与众不同之处，因此以World's smallest foldable bicycle arriving为题既具有高度的概括性、强烈的针对性，又因口吻激动、催人奋进而具有一定的醒目性。
5. B。细节判断题，可用逻辑推断法来解。原文最后一节...the next step for the A-bike was to add an electric motor in a few years. 体现答案。
