That"s where the similarities end: this bag can wirelessly keep track of your belongings and remind you, just as you"re about to leave the house, to take your wallet. It can review the weather report and suggest that you take an umbrella. This purse can even upload your favorite songs onto your scarf.
Surely, a computing purse and scarf set may seem like the stuff of science fiction. But these devices, part of next generation of wearable computers, could become commonplace within a few years. Dupont created new super strong fibers that can conduct electricity and can be woven into ordinary-looking clothes. And the chipmaker developed chip packaging allowing wearable computers to be washed, even in the heavy-duty (耐磨损的) cycle.
As a result, these new wearable devices are different from the heavy and downright silly versions of the recent past, which often required users to be wrapped in wires and type on their stomachs. Unlike their predecessors, these new wearable computers also make economic sense. When her bag becomes commercially available in two to three years, Nanda expects it will cost around $ 150, which is the price of an average leather purse.
Here"s how the bag works: You place a special radio-signal-transmitting chip onto your wallet. A similar radio in your purse picks up the signal and notifies you that you"ve forgotten to take your wallet. In turn, sensors on your purse"s handles will notify the computer that you"ve picked up the purse and are ready to go.
Already, these new kinds of wearable devices are being adopted for use in markets like auto repair, emergency services, medical monitoring - and even, increasingly, for consumers at large. Indeed, more people will want to cross that bridge in the coming years - making for a booming market for wearable computers that don"t look like something out of science fiction.
小题1: According to the passage, the new wearable computers _______.
A.require users to operate on the stomach |
B.pick up the signals through wires and chips |
C.are being applied in some different areas now |
D.are smarter but more expensive than the old ones |
A.The new wearable computers have become fashionable. |
B.People would like to learn more about the new computers. |
C.New wearable computers promise to sell well in the future. |
D.The idea of the purse-like computers comes from science fiction. |
A.introduce a new kind of computer |
B.explain the functions of computers |
C.compare different types of computers |
D.show how high technology affects our life |

One common problem gifted kids face is that they, and those around them, place too much importance on being smart. Such an emphasis can encourage a belief that bright people do not have to work hard to do well. Although smart kids may not need to work hard in the lower grades, whe

IQ is just one element among many in the recipe for success—Children develop well or struggle in school for a host of reasons apart from IQ. These include motivation and persistence, social competence, and the support of family, educators and friends.
Because highly gifted children solve the most varied thought problems faster and more thoroughly than those with more average talents do, they need additional intellectual stimulation while they wait for the rest of the kids to learn the basics. Two central approaches are used to satisfy the educational needs of such children: acceleration and enrichment. Acceleration means studying material that is part of the standard subjects for older students. Enrichment involves learning information that falls outside the usual subjects.
A child might skip one or more grades as a way of accelerating in school. But being with older children for the entire school day—and perhaps for grade-based extracurricular activities such as sports—can make a child feel inferior in every filed outside of academics. One very bright fourth-grader who had skipped two grades remained far ahead of his classmates i

Contraction of front and side parts, as cells(细胞) die off, was seen in some people in their thirties, but it was still not found in some sixty and seventy-year-olds.
Matsuzawa concluded from his tests that there is a simple way to prevent the contraction---using the head.

Asteroids are bigger versions of the meteoroids(流星)that race across the night sky. Most orbit the sun far from Earth and don"t threaten us. But there are also thousands whose orbits put them on a collision course with Earth.

The cure,though,might be worse than the disease. Do we really want fleets of nuclear weapons sitting around on Earth? “The world has less to fear from doomsday(毁灭性的) rocks than from a great nuclear fleet set against them,” said a New York Times article.

When you take the Holmes Rahe you must remember that the score does not show how you deal with stress -- it only shows how much you have to deal with. And we now know that the way you deal with these events dramatically affects your chances of staying healthy. By the early 1970s, hundreds of similar studies had followed Holmes and Rahe. And millions of Americans who work and live under stress worried over the reports. Somehow the research got boiled down to a memorable message. Women’s magazines ran titles like “Stress causes illness.”
If you want to stay physically and mentally healthy, the articles said, avoid stressful events. But such simplistic advice is impossible to follow. Even if stressful events are dangerous, many -- like the death of loved one--are impossible to avoid. Moreover, any warning to avoid all s

Warnings from neuroscientist (神经系统科学家) Susan Greenfield will disturb the millions whose social lives depend on surfing their favorite websites each day.But they will strike a chord (弦) with parents and teachers who complain that many teenagers lack the ability to communicate or concentrate away from their screens.
More than 150 million use Facebook to keep in touch with friends, share photographs and videos and post regular updates of their movements and thoughts.A further six million have signed up to Twitter, the "micro-blogging" service that lets users exchange text messages about themselves.But while the sites are popular and extremely profitable, a growing number of psychologists and neuroscientists believe they may

Baroness Tarot, an Oxford University neuroscientist believes repeated exposure could rewire the brain.Computer games and fast-paced TV shows were also a factor, she said."My fear is that these technologies are weakening the brain to the state of small children who are attracted by buzzing noises and bright lights, who have a small attention span and live for the moment." "I often wonder whether real conversation in real time may eventually give way to these easier and faster screen dialogues, in much the same way as killing and butchering an animal to eat has been replaced by the convenience of packages on the supermarket shelf," she said.

A study by the Broadcaster Audience Board found teenagers now spend seven and a half hours a day in front of a screen.Educational psychologist Jane Healy believes children should be kept away from computer games until they are seven.Most games only excite the "flight or fight" areas of the brain, rather than the areas responsible reasoning.
