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 sown 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 he used in hospitals to operate heart pacemakers(起博器), 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 should be ready in one year.
The developers hope the device will one day help developing countries; nearly 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 walking. 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.

It was blazing hot, just like most July days. I stepped into a tiny ice-cream shop to cool off with a chocolate ice-cream. It was an old woman bent over a table near the door. Her back was so badly twisted that her face nearly touched the tabletop. I sat down facing her a couple of tables away.
“Poor woman,” I thought, “What does she get out of life? Why God let people live so long past their prime?”
As I thought, another aged lady entered the shop and sat down with her. Soon the two of them were talking about childhood days. They talked of how little the shop had changed in 70 years. In minutes, the two of them were trembling with laughter.
I looked again at the first woman, then in the mirror on a nearby wall, catching a picture of myself. I was wearing a dirty shirt. She was well dressed in white, her hands sparking with gold rings. I was sad. She was laughing, smiling. I was putting the pieces of my life together. She had millions of wonderful memories to recall. I sat alone. She was sharing the day with a good friend. I was secretly worried about getting old. She was old, but it wasn’t hurting her.
As I left the shop, I thought of my foolish question about God letting people live past their prime. Why, that woman was more alive, more sensitive to life than I was. Age has not bent her spirit.

One night recently, I was driving down a two-lane highway at about 60 miles an hour. A car approached from the opposite direction at about the same speed. As we passed each other, I caught the other driver’s eye for only a second. I wondered whether he might be thinking, as I was, how dependent we were on each other at that moment. I was relying on him not to fall asleep, not to be put off by a phone conversation, not to cross over into my lane and bring my life to a sudden end. Though we had never spoken a word to each other, he relied on me in just the same way.
Multiplied a million times over, I believe that is the way the world works. At some level, we all depend upon one another. Sometimes that dependence requires us simply not to do something like crossing over the double yellow line. And sometimes it requires us to act cooperatively, with friends or even with strangers.
As technology shrinks our world, the need increases for cooperative action among nations. In 2003, doctors in five nations were quickly organized to identify the SARS virus, which saved thousands of lives. The threat of international terrorism has shown itself to be a similar problem, one requiring coordinated action by police and intelligence forces across the world. We must recognize that our fates (命运) are not ours alone to control .
In my own life, I’ve put great stock in personal responsibility. But, as the years have passed, I’ve also come to believe that there are moments when one must rely upon the good faith and judgment of others. So, while each of us faces the case of driving alone down a dark road , what we must learn is that the approaching light may not be a threat , but a shared moment of trust.
1.The author considers ________ very important.
A.driving alone on a dark road B.shared trust and cooperation
C.cooperation to identify SARS virus D.independence of people

A.the approaching car was very dangerous

3.From the second paragraph, we know the author drew the important lesson from ________.
A.only one experience B.many friends and strangers
C.a driver on a dark road D.many similar experiences
4.The need for cooperation increases because _________.
A.terrorism can happen everywhere

A.had a change on his viewpoint of life
