Imagine you’re at a party full of strangers. You’re nervous. Who are these people? How do you start a conversation? Fortunately, you’ve got a thing that sends out energy at tiny chips in everyone’s name tag (标签). The chips send back name, job, hobbies, and the time available for meeting-whatever. Making new friends becomes simple.
This hasn’t quite happened in real life. But the world is already experiencing a revolution using RFID technology.
An RFID tag with a tiny chip can be fixed in a product, under your pet’s skin, even under your own skin. Passive RFID tags have no energy source-batteries because they do not need it. The energy comes from the reader, a scanning device, that sends out energy (for example, radio waves) that starts up the tag immediately.
Such a tag carries information specific to that object, and the data can be updated. Already, RFID technology is used for recognizing each car or truck on the road and it might appear in your passport. Doctors can put a tiny chip under the skin that will help locate and obtain a patient’s medical records. At a nightclub in Paris or in New York the same chip gets you into the VIP section and pays for the bill with the wave of an arm.
Take a step back: 10 or 12 years ago, you would have heard about the coming age of computing. One example always seemed to surface: Your refrigerator would know when you needed to buy more milk. The concept was that computer chips could be put everywhere and send information in a smart network that would make ordinary life simpler.
RFID tags are a small part of this phenomenon. “The world is going to be a loosely coupled set of individual small devices, connected wirelessly,” predicts Dr. J. Reich. Human right supporters are nervous about the possibilities of such technology. It goes too far tracking school kids through RFID tags, they say. We imagine a world in which a beer company could find out not only when you bought a beer but also when you drank it. And how many beers. Accompanied by how many biscuits.
When Marconi invented radio, he thought it would be used for ship-to-shore communication. Not for pop music. Who knows how RFID and related technologies will be used in the future. Here’s a wild guess: Not for buying milk.
The article is intended to .
A. warn people of the possible risks in adopting RFID technology

Have you ever asked yourself why children go to school? You will probably say that they go to learn their own language and other language, arithmetic, geography, history, science and all the other subjects. That’s quite true, but why do they learn these things? And are these things all that they learn at school?
We send our children to school to prepare them for the time when they become big and have to work for society. They learn their own language so that they will be able to tell others clearly what they want and what they know, and understand what others tell them. They learn foreign languages in order to be able to benefit from what people in other countries have written and said, and in order to make people from other countries understand what they themselves mean. They learn arithmetic in order to be able to measure and count things in their daily life, geography in order to know something about the world around them, and history to know something about the human beings they meet every day. Nearly everything they study at school has some practical use in their life, but is that the only reason why they go to school?
No. There is more in education than just learning facts. We go to school above all to learn how to learn, so that when we have left school, we can continue to learn. A man who really knows how to learn will always be successful, because whenever he has to do something new which he has never had to do before, he will rapidly teach himself how to do it in the best way. The uneducated person, on the other hand, is either unable to do something new, or does it badly. The purpose of schools, therefore, is not just to teach languages, arithmetic, geography, etc, but to teach pupils the way to learn.

查看习题详情和答案>>skills and knowledge from being lost. The charmers, who make snakes dance to the sound of flutes, used
to be a traditional feature of Indian life, performing in towns and villages, until they were banned in 1972
to control the trade in snake skins.
The government is now considering a plan to train the saperas, as they are known, to visit schools and zoos to tell children about forests and wildlife. There is also a proposal to set up a "dial a snake charmer"
service to help householders to deal with unwelcome intruders.
"For generations they have been a feature of Indian life but now they can't earn a living for fear of
arrest," said Behar Dutt, a conservationist behind the plans," if a policeman doesn't catch them, animal rights activists report them."
Many snake charmers have continued to work clandestinely(暗中地) since the ban, despite the threat of up to three years in jail. But their trademark clothcovered baskets, hung from a bamboo pole carried
across their shoulders, make them an easy target for police.
The fate of Shisha Nath, 56, from Badarpur, a village just outside of New Delhi, is typical of practitioners(从业者) of the dying art. "I used to earn enough to support my family and send my children to school,"
he said. "Now it's hard to earn even $1 a day. My children want to be snake charmers. It's our identity.
We love the work. But it's become impossible."
Next month Dutt's project to train 30 snake charmers will begin at a snake park in Pune, western India, where experts will enrich their homegrown skills with some formal knowledge.
More than the law, though, it is the dishonest attitude of their fellow countrymen that anger many snake charmers. "We're disturbed all the time but when people want a snake removed from the house, they rush
to us," said Prakash Nath, who was ordered recently to the home of Sonia Gandhi, the Congress party
leader.
