For years, Europeans have been using "smart cards" to pay their way through the day. They use them in shops and restaurants, plug them into pubic into telephones as and parking meters. In France smart cards cover anything from a bistro bill to a swimming -pool entry fee. In American, smart cards are not nearly so common -- only about 43,000 are now circulating in the US and Canada -- but Forrester Research of Cambridge, Mass. , predicts that number will balloon to 4.7 million by the year 2002.
What is a smart card, exactly, and how does it work
Also called a chip card because of the tiny mixcroprocessor embedded in it, a smart card looks like the other plastic in your wallet. To make things more confusing, some smart cards pull double duty as regular ATM bank cards. The difference is that when you swipe your ATM ( or debit) card at the grocery - store checkout, you’re draining cash from your bank account. Smart cards, on the other hand, are worthless unless they are "loaded with cash value", pulled directly from your bank account or traded for currency. The chip keeps track of the amounts stored and spent. The advantage, in theory, is convenience: consumers bother less with pocket change and are able to use plastic even at traditionally cash -only vendors. The electronic transaction doesn’t require a signature, a PIN number or bank approval. Downside: lose the card, lose the money.
Most people are probably more familiar with stored -value cards equipped only with a magnetic strip, such as fare card issued to riders on the Washington metro or the New York City subway. The newer chip - enhanced versions, armed with more memory and processing power, have popped up in various places in the past years or so, from college campuses to military bases to sports stadiums. Other experiments are under way. A health -care claims processor in Indianapolis, Ind. , hopes smart cards will streamline medical - bill payments. In Ohio, food - stamp recipients receive a smart card rather paper vouchers.
Smart cards issued for general commerce are rarer, unless you happen to live in a place designated for a test run, such as Manhattan’s Upper West Side. But big bank and plastic - purveying kings Visa and MasterCard are hot for the idea, promising more extensive trials and more elaborate, multipurpose cards capable of rendering everything else you carry -- plastic, paper or coin-- superfluous.
Today’s smart cards may not be revolutionizing the way we buy the morning paper yet, but they could turn out to be right tool spur Internet commerce and banking. For the time being, though, smart cards are just another way to buy stuff. And it could be a while before even that catches on. Remember: some people still don’t trust ATMs either.
The aim of the article is to ______.

A. show how to use smart cards.
B. show the difference between ATM card and chip card.
C. how the smart cards have become popular.
D. persuade Americans to use smart cards.

Which of the following is NOT the point of the last paragraph [A] To describe how fantastic the dance is. [B] To express his gratefulness to god. [C] To show his deep feeling after seeing the dance. [D] To share with readers his understanding of the dance.
Amongst them—though all were delightful—there were two who especially riveted my attention. The first of these two was the tallest of all the children, a dark thin girl, in whose every expression and movement there was a kind of grave, fiery love.
During one of the many dances, it fell to her to be the pursuer of a fair child, whose movements had a very strange soft charm; and this chase, which was like the hovering of a dragonfly round some water lily, or the wooing of a moonbeam by the June night, had in it a most magical sweet passion. That dark, tender huntress, so full of fire and yearning, had the queerest power of symbolising all longing, and moving one’s heart. In her, pursuing her white love with such wistful fervour, and ever arrested at the very moment of conquest, one seemed to see the great secret force that hunts through the world, on and on, tragically unresting, immortally sweet.
The other child who particularly enhanced me was the smallest but one, a brown-haired fairy crowned with a half moon of white flowers, who wore a scanty little rose-petal-coloured shift that floated about her in the most delightful fashion. She danced as never child danced. Every inch of her small head and body was full of the sacred fire of motion; and in her little pas seul she seemed to be the very spirit of movement. One felt that Joy had flown down, and was inhabiting there; one heard the rippling of Joy’s laughter. And, indeed, through all the theatre had risen a rustling and whispering; and sudden bursts of laughing rapture.
I looked at my friend; he was trying stealthily to remove something from his eyes with a finger. And to myself the stage seemed very misty, and all things in the world lovable; as though that dancing fairy had touched them with tender fire, and made them golden.
God knows where she got that power of bringing joy to our dry hearts: God knows how long she will keep it! But that little flying Love had in her the quality that lie deep in colour, in music, in the wind, and the sun, and in certain great works of art—the power to see the heart free from every barrier, and flood it with delight.
