Electrical devices(儀器) could soon use power made by human energy. Scientists say they have developed an experimental device that produces electricity from the physical movement of a person walking. British scientist Max Donelan and other scientists in Canada and the United States developed the device.

The device connects to a person’s knee. As the person walks, the device captures energy each time the person slows down. To do this, the device helps with the slowing down movement of the leg. The movements of the walking person push parts of a small machine that produces electricity. Using the device, an adult walking quickly could produce thirteen watts of electricity in just a minute. Donelan says walking at that speed could produce enough power to operate a laptop computer for six minutes.

There are several possible uses for the device. Developers say it could help people who work in areas without electricity to operate small computers. The device could also be used in hospitals to operate heart pacemakers(起搏器). It could even be used to assist in the movement of robotic arms and legs.

The experimental version of the device weighs about one and a half kilograms, but it is too costly for most people to buy. But the researchers hope to make a lighter, less costly version. An improved version shou1d be ready in one year.

The developers hope the device will one day help developing countries. Near1y twenty five percent of people around the world live without electric power.

A similar product was invented in 2005 by Larry Rome of the University of Pennsylvania. He created a bag carried on a person’s back that also produces power from wa1king.

The knee device does not produce as much electricity as the bag. But the bag requires the walker to carry a load of twenty to thirty kilograms.

 

47. The second paragraph mainly talks about         .

A. who developed the device

B. how the device works

C. several possible uses for the devices

D. how much electricity the device can produce

48. Compared with the device designed by Larry Rome, this new device          .

A. produces power without adding more loads to the walker

B. can produce more power in a much shorter time

C. needs to be equipped with a battery

D. can help the walker wa1k faster

49. From the passage, we can learn that the electrical device can          .

A. help housewives operate the washing machine

B. make it much easier for us to go online

C. produce more electricity than that invented by Larry Rome

D. be applied in medicine to operate heart pacemakers

50. What would be the best title for the passage?

A. First device powered by walking wi1l soon be on the market

B. Advanced technology brings in a new way to operate heart pacemakers

C. Device gives new meaning to the idea of power walking

D. Human energy will become a main source of electricity
