The Internet has led to a huge increase in credit-card(信用卡) fraud. Your card information could even be for sale in an illegal Web site(網(wǎng)站).Web sites offering cheap goods and services should be regarded with care. On-line shoppers who enter their credit-card information may never receive the goods they bought. The thieves then go shopping with your card number—or sell the information over the Internet.?

Computers hackers(黑客) have broken down security(安全) systems, raising questions about the safety of cardholder information. Several months ago,25 000 customers of CD Universe, an on-line music retailer(批發(fā)商),were not lucky. Their names,addresses and credit-card numbers were posted on a Web site after the retailer refused to pay US $157 828 to get back the information.?

Credit-card firms are now fighting against on-line fraud. MasterCard is working on plans for Web-only credit card, with a lower credit limit. The card could be used only for shopping on-line.

However, there are a few simple steps you can take to keep from being cheated.?

Ask about your credit-card firm's on-line rules: Under British law, cardholders are responsible?(對……負有責任的) for the first US $78 of any fraudulent spending.?

And shop only at secure sites: Send your credit-card information only if the Web site offers-advanced secure system.?

　　If the security is in place, a letter will appear in the bottom right-hand corner of your screen. The Web site address may also start with https://—the extra “s” stands for secure. If in doubt, give your credit-card information over the telephone.?

Keep your password safe: Most online sites require a user name and password before placing an order. Treat your passwords with care.?

What do most people worry about the Internet according to this passage??

A. A lot of stolen credit-cards were sold on the Internet.?

B. Fraud on the Internet.?

C. Many Web sites are destroyed.?

D. Many illegal Web sites are on the Internet.

What is the meaning of “fraud”??

A. cheating    B. sale     C. payment   D. safety

How can the thieves get the information of the credit-card??

A. The customers give them the information.?

B. The thieves steal the information from Web sites.?

C. The customers sell the information to them.?

D. Both A and B.

How many pieces of advice does the passage give to you??

A. Four.  B. Three. C. Five.   D. Six.

In a few years, you might be able to speak Chinese, Korean, Japanese, French,and English—and all at the same time. This sounds incredible, but Alex Waibel,a computer science professor at US's Carnegie Mellon University (CMU) and Germany's University of Karlsruhe,?announced? last week that it may soon be reality. He and his team have invented software and hardware that could make it far easier for people who speak different languages to understand each other.?

One application, called Lecture Translation, can easily translate a speech from one language into another. Current translation technologies typically limit speakers to certain topics or a limited vocabulary. Users also have to be trained how to use the programme.?

Another prototype(雛形機) can send translations of a speech to different listeners depending on what language they speak.“It is like having a simultaneous translator right next to you but without disturbing the person next to you,” Waibel said.?

Prefer to read? So-called Translation Glasses transcribe(轉(zhuǎn)錄) the translations on a tiny liquid-crystal(液晶) display(LCD) screen.?

Then there's the Muscle Translator. Electrodes capture the electrical signals from facial muscle movements made naturally when a person is mouthing words. The signals are then translated into speech. The electrodes could be replaced with wireless chips implanted in a person's face, according to researchers.?

During a demonstration held last Thursday in CMU's Pittsburgh campus, a Chinese student named Stan Jou had 11 tiny electrodes attached to the muscles of his cheeks, neck and throat. Then he mouthed—without speaking aloud—a few words in Mandarin(普通話) to the audience. A few seconds later, the phrase was displayed on a computer screen and spoken out by the computer in English and Spanish: “Let me introduce our new prototype.”?

This particular gadget(器械),when fully developed, might allow anyone to speak in any number of languages or, as Waibel put it, “to switch your mouth to a foreign language”. “The idea behind the university's prototypes is to create ‘good enough’ bridges for cross-cultural exchanges that are becoming more common in the world,” Waibel said.?

With spontaneous(自發(fā)的) translators, foreign drivers in Germany could listen to traffic warnings on the radio, tourists in China could read all the signs and talk with local people, and leaders of different countries could have secret talks without any interpreters there.?

Which of the following statements is not TRUE??

A. A lecture translation can translate what you said into other languages easily.?

B. There is no Muscle Translator in the world now.?

C. Muscle Translators can translate what you think into speech if you just move your mouth.?

D. The spontaneous translators will help us a lot.

What kind of equipment is NOT mentioned in this passage?

A. Lecture Translation.

B. Muscle Translator.?

C. Multiple Translator.

D. Translation Prototype.

What's the final destination of inventing the language translators??

A. To make cultural exchanges between different countries easier.?

B. To help students learn foreign languages more easily.?

C. To make people live in foreign countries more comfortably.?

D. To help people learn more foreign languages in the future.

Where can this passage probably excerpted from?

A. A newspaper.    B. A magazine on science.?

C. A fairy tale.       D. A scientific fantasy book.
