Electrical devices could soon use power make 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 deice could also be used in hospitals to operate heart pacemakers ,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. 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 walk faster

Q: There is one language that is used in every country in the world. The people who use it are young and old, short and tall, thin and fat. It is everybody's second language. It is easy to understand, although you can't hear it. It is sign language. When you wave to a friend who is across the street, you are using sign language. When you smile at someone, you are saying, "I want to be friendly", but you are not using speech. You are using body language. When you raise your hand in class, you are saying, "Please ask me. I think I know the correct answer." Babies who can't talk can point at things. They are using sign language. A policeman who wants to stop traffic holds up his hands. He is using sign language. Many years ago, a French priest, Charles Michel de Epee, became interested in education for deaf people. He invented a finger alphabet . It is still in use. People can make the sign for letters and spell words with their hands, and deaf people can read and understand them. Soon there were schools for the deaf in many countries. The only university for the deaf is Gallaudet College in Washington, D.C. Today, in the United States, there are special TV news programs for deaf people. The newsreader tells the news in sign language. At the same time, the words appear on the TV screen. The actors in the Theatre of Deaf don't spell every word. Sometimes they use hand signs. When they put two hands together, it means sandwich. They can make a roof with their hands when they want to show a house. One finger in front of an actor's mouth can mean quiet. You can talk to people who are behind windows that are closed. And when you go swimming with your friends, you can have conversations under water. How many hand signs do you use every day? The passage is mainly about _ . A) an introduction to sign language B) the importance of sign language C) a famous priest in France D) how to use sign language

There is a growing problem of what to do with electronic waste such as old televisions, computers, radios, cellular telephones and other electronic equipment. Electronic trash, or e-waste, is piling up faster than ever in American homes and businesses. People do not know what to do with old televisions or computers, so they throw them in the trash. National Solid Wastes Management Association (NSWMA) state programs director Chaz Miller says the large amount of electronic waste Americans produce is not unexpected. The US Environmental Protection Agency (EPA) estimates more than 400 million consumer electronic items are dumped each year, and there is a push by more states to ban the waste from landfills and create recycling programs. They can be torn apart and sorted for useable parts. Mike Fannon who runs the plant in Baltimore, says, "There are a lot of valuable metals that can be recovered and reused instead of just putting them in the landfill, and in certain components, there are some materials that should not really be in the landfill," Fannon explains. Fannon says nearly 20 percent of electronic waste is recycled nationwide. Thirteen years ago, it was only about 6 percent. Recycling rates continue to rise as more communities have banned electronics from landfills in an effort to keep e-waste poisons like lead and mercury out of garbage dumps. This year, several states like Vermont imposed a ban on electronic waste in landfills. More than 25 other states have also adopted landfill bans, e-waste recycling programs or both. Chaz Miller says more can be done to boost electronic waste recycling. "We can do much better," noted Miller. "I think clearly our goal should be to do as well as we do recycling newspapers." According to Mike Fannon, what might be the best way of dealing with e-waste? A) Recycling it. B) Selling it. C) Burying it. D) Breaking it.
