听力原文： The Credit Card in the U. S.
Today, more and more people in the U. S. are using credit cards instead of money to buy what they need. Almost anyone who bas a steady income and a continuous work record can apply for a credit card.
With a credit card, you can buy a car, eat a dinner, take a trip, and even get a haircut by charging the cost to your account. In this way, you can pay for purchases a month or two later. Or you may choose to spread out your payments over several months and pay only part of the total amount each month.. With a credit card , you don’t have to carry much cash and you don’t have to be concerned about losing your money through carelessness or theft. The card user only has to worry about paying the final bill. This of course can be a problem if you charge more than you can pay for.

Credit Card .Only Works When Spoken to
A credit card that will not work unless it hears its owner's voice could become an important weapon in the fight against fraud.
The card requires users to give a spoken password that it recognizes using a built-in voice-recognition chip. The idea is to prevent thieves using a stolen card or fraudsters using someone else's credit card details to buy goods online.
A prototype built by engineers at Beepcard in Santa Monica, California, represents the first attempt to pack a microphone, a loud speaker, a battery and a voice-recognition chip into a standard sized credit card.
They are not quite there yet: the card is the length and width of an ordinary credit card, but it is still about three times as thick. Alan Sege, Beepcard's CEO, says the company now plans to use smaller chips to slim it down to normal thickness.
The voice card is based on an earlier Beepcard technology designed to prevent fraud in online transactions. This earlier card has no microphone, but has a built-in loudspeaker that it uses to "squawk" an acoustic ID signal via a computer's microphone to an online server.
By verifying that the signal matches the card details, the server can establish that the user is not simply keying in a credit card number but actually has the card to hand. 'The ID code changes each time the card is used in a pre-ordered sequence that only the server knows.
This prevents fraudsters recording the beeps, noting the card details and then playing back the audible ID when they key in the details later. But this earlier technology cannot prevent fraudulent use of stolen cards. The new one can.
The new voice card also identifies itself by its 1D squawk, but it will not do this until it has
verified the legitimate user's spoken password. Thieves will be unable to use the card because even if they knew the password they would have to be able to copy the owner's voice with a high degree of accuracy.
The challenge for Beepcard has been to develop voice-recognition and audio circuitry that can be powered by a mini battery embedded in a credit card. To maximize battery life, the electronics are only switched on when the card is being used. Pressing a button on the card's surface prompts it to utter "Say your password" in female voice. If the voice-recognition software proves that the password is authentic, it sends its ID squawk which the server then identifies, allowing the transaction to proceed.
fraudster n. 骗子
beep n. (电子装置发出的)嘟嘟声
onlineadj. &adv.联机的(地)，的(地)；实时操作的(地)
legitimate adj.合法的
fraudulent adj.欺骗性的；骗得的

How can the credit card recognize the spoken password given by the user？
A．By using a voice-recognition chip embedded in the card.
B．By using a voice-recognition device built in the server.
C．By fixing a microphone in the card.
D．By fixing a loudspeaker in the card.
听力原文： Credit cards are big business. Americans spend $16 billion a year on cards and there are already 590 millions of them in circulation. Many banks sponsor their own credit card companies and issue cards free to their customers. Other credit card companies charge their members annual dues. The stores that accept credit cards must pay a small fee to the credit card company—a percentage of the purchase price of the merchandise or service. Credit card companies make a profit from the fees they charge the store and also from the fees collected from customers who pay for their charges in monthly installments. However, credit card companies sometimes have problems collecting overdue payments from unreliable customers. Also, the use of stolen, lost or counterfeit credit cards by criminals has become a big headache for the credit card company that is responsible for the goods and services illegally charged to its customer's account.
Yet, in many ways, the big loser in the credit card system is not the credit card company, the store, or the card user, but rather the general customer. The store makes up for the fees it pays to the credit card company by increasing prices for goods and services. Stores may have more sales if they accept cards, but the added cost to the store when credit cards are accepted instead of cash is actually passed on to all customers in higher prices. In this way the cash customer suffers for the convenience the credit card customer enjoys.
(33)
A．The bank.
B．The store that accepts the card.
C．The credit card company.
D．The customer himself.
