Electrical devices(仪器)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.
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

A.It is too heavy for the walker to bear. B.It is too complex for people to use. C.It is too expensive for most people to afford. D.It will slow down one’s walking speed.

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

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

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

I the first sock shop that caught my eye, and , not more than 17, came forward. "What can I do for you, sir?" "I wish to a pair of socks." glowed. "Did you know that you had come into in the world to buy socks?" I had not been that, as my entrance had been accidental. "Come with me,” said the boy happily. He began to down from the shelves box after box.
" , boy, I'm going to buy only one pair!" "I know that, but I want you to see how beautiful these are. Aren't they wonderful?" There was an expression of joy, he were revealing(透露) to me the of his religion. I became far more interested in him than in the socks.

My amazement at his pride in will be understood by all who read this article. In many shops the customer has to wait for someone to him. When some clerk does notice you, you are made to feel as if you were interrupting him. possibly that very clerk who is now so began his career with enthusiasm. The freshness ; he became a mechanical salesman.
