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
One day I was walking to the mailbox with my dad,when I saw something drop from a tree.I couldn't what it was,so I kept my eyes on the spot as we came near .It was a baby bird,which had fallen from its nest.It had long,awkward wings and feet,and that fought to stay open .It was , so I sat next to it watching while my dad got the mail.I its nest and mother , what would happen to it.
My dad and we had to it;there was nothing we could do.He said if the bird mother smelled any traces(踪迹) of ,she wouldn't go near the again.
As we began to walk away,a woman .”Did it fall out of a nest ?”she asked.
“Yeah.”I answered.
“It a lot. Not much we can do,”she said .”Try not to think about it when you go to sleep tonight.”
I walked the mailbox the next day.The baby bird lay in the grass.
I realize that “Try not to think about it” is the of many people towards things which to provide them with perfect excuses not bothering . The woman wasn't being ; she was actually quite nice. But when everyone says”there's I can do —just try not to think about it,”Where will we finally ? When billions of people try not to think about it When they go to bed at night, there might be millions of fallen birds lying dead and in the grass the next morning.

I loved working with my dad, but I hated a summer job he gave me. He owned a small in Bank Street. In his shop, the most recently person got the worst job, and the boss’ son was also .
I didn’t want to spend hours the frost on the ceiling of the walk-in freezer, and it was the Saturday afternoon’s job that I hated most. We received fresh every day. Chicken sat in wooden boxes and was with crushed ice. During the week, the ice and the blood of the chicken slowly leaked into the container the chicken, creating its bloody smell.
There was only one to get rid of the blood and wash the container: hold my and carefully slide the container from under the chicken, as I tried not to the contents over my clothes, and then into the drain(下水道).
Soon, students who have cut lawns, painted houses, worked in offices, maybe even worked in the butcher’s will to school. Some will have great memories others will come back with ones.
Looking back, I think my father could have me from my weekly hell. However, my dad, who’d dropped out of school to help support his family after his father died, was a teacher for me . He knew treating me from his other employees would be an unfair thing. Most importantly, he taught me to those who do the hard and tasks in life.
For the next six summers, I returned not as the boss’ son, but as one of other guys, and I cleaned the dirty container every Saturday afternoon.

What is real success? I am sure many would come up with answers like lots of money, a big house, a new car, and so on.
It has been interesting to see how my own idea of success has through the years. When I was young, I was eagerly reaching for material success. I chose my jobs accordingly and ended up in . Sure enough, I did earn some pretty good pay checks.
But then a different feeling started to . I began to realize selling was not what I wanted to do all my life. After all I was often forced to sell products that did not really suit customers. All that matters is the amount of money that is made. I became very unhappy.
I came to realize that even with big pay checks I did not feel successful. That is when my search for success turned inwards, I sales and chose another profession–helping people. The feeling of relief and belonging was great–and suddenly I felt successful again. Even though I earned than before, I was much more content.
Then I returned to my old love–writing.
I realized I felt most successful when I loved what I did never the money. Then for my own I define success by the feeling of contentment.
Always remember–you are not here to anyone else’s life but your own. It is not your obligation (义务) to please others with your life – only yourself, because only if you are happy yourself can you happiness to others. You cannot give what you do not have.
So be true to yourself and your own joyful path to your own of success.
