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.

Looking smart in a blue button-down shirt,Jorge Magana,18,zipped through a PowerPoint(PPT) presentation with confidence. Seated in front of Magana in a classroom at Los Angeles High School of the Arts were three judges: the school’s Assistant Headmaster,a school coordinator,and a former student. The occasion was his senior defense. Magana was trying to convince the judges that he was ready to graduate.
He had 45 minutes to present his portfolio(作品选集) from three aspects: one academic,one artistic,and one of his own choosing. The judges grilled him: Can you describe your research process? Which difficulties did you face and how did you overcome them? How will the skills you learned help with your future plans?
Portfolio assessments like this one,which are considered by educators nationwide as a proven path to college success,have largely been squeezed out by standardized tests,the quicker,less costly measure of student performance. But the state’s reliance on test scores to rank school performance is about to change,and educators see an opportunity. For now,the goal at the Los Angeles Unified School District is to make the portfolio defense a graduation requirement. Ten high schools are testing the portfolio assessment,and there are plans to get more schools on board next school year.
At first,many teachers at Los Angeles High School of the Arts thought the defense was unnecessary. Then,they actually witnessed the defenses. “You can see your students reflect on what they’ve learned,and see how that learning has affected them,” says Isabel Morales,a 12th grade social studies teacher. “Watching the defenses taught me how much my lessons count,how important it is for me to provide a new learning experience for my students. ”
1.Why is Jorge Magana mentioned in the text?
A.To lead in the topic of the passage.
B.To introduce what the senior defense is.
C.To present how to make a senior defense.
D.To stress difficulties of portfolio defenses.
2.What can we know about portfolio assessments from paragraph 3?
A.They require low investment.
B.They are being widely promoted.
C.They completely replace standardized tests.
D.They are common at high school.
3.What is Isabel Morales’ attitude to portfolio defenses?
A.Disapproving. B.Worried.
C.Doubtful. D.Supportive.
