Electrical devices 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 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. The movements of the walking person push parts of a small machine that produces electricity. Using the device, 22an adult walking quickly could produce thirteen wars of electricity in just a minute. Max 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. 23The device could also be used in hospitals to operate heart pacemakers; it c
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.

[填空题]The Price of Idleness
1．Electrical devices such as CD players, vidoes and burglar alarms are consuming more energy in standby mode than when they are actually being used.
2．Maria Sanchez and her colleagues from the Lawrence Livermore National Laboratory in Berkeley, California, tested more than 50 small electrical applicances, from computers to doorbells, electric mowers, VCRs, and pool pumps. In the current issue of Energy Policy, they report that about half of all consumer electronics energy is used in standby mode. This costs American consumers ＄1 billion a year in wasted energy.
3．The researchers say that while electronic devices are lying dormant(休眠状态),running their clocks, maintaining internal memories or displaying their settings, they consume aroud 40 terawatt hours of electricity in the U.S. every year--enough to power a city such as Chicago or London. Many machines use almost as much power on standby as when working. For example, it takes 15 watts to play a t

Soon after I graduated from college, I was lucky enough to get a job in a department store. I worked there for three years as a secretary to the manager. Then I was promoted to the position of his assistant. I stayed on that job for another year, but then I got bored and decided to leave. I applied for other jobs in the same area. But I had no luck getting a second job. So in the end, I had to work as a waitress in a restaurant. Well, I wasn’t very successful, because I kept dropping things. After a few weeks, I lost my job again. Then, just by chance, I met an old friend. She found me a job as a television presenter on a program called "Business Today". This is the job I’m now doing. It is very interesting and I love it.
