The card using a built-in voice-recognition chip requires users to give a spoken password that it recognizes. The idea is to prevent thieves from using a stolen card to buy goods online.  A model built by engineers in California packs a microphone, a loudspeaker, a battery and a voice-recognition chip into a standard-sized credit card. The card is the length and width of an ordinary credit card but about three times as thick. The company now plans to make it thinner.  The voice card is based on an earlier Beep card technology designed to prevent fraud in online deals. The Beep card has no microphone, but has a built-in loudspeaker to utter an audible   ID signal by a computer's microphone to an online server . By confirming that signal matches the information in the card, the server can make sure that the user is not simply keying in a credit card number but actually has the card in his hand. The ID code, which only the server knows, changes each time the card is used.  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 Beep card technology cannot prevent illegal use of stolen cards. The new voice card can. The new voice card doesn't identify itself by its ID until it has confirmed the real 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 Beep card has been to develop voice-recognition and audio circuitry .  The voice-recognition credit is powered by a mini battery. To extend batter life, the electronics have only to be switched on when the card is being used. Pressing a button on the card's surface allows one to hear a female voice saying, "Say your password." If the voice-recognition software proves that the password is real, it sends its ID, which the server then identifies, allowing the deal to continue. Why is the voice credit an important innovation? A) It is cheap to make and buy. B) It can leave voice messages. C) It makes online shopping easy. D) It makes fraud more difficult.

It is easy to find your way about in New York. It is _ so regularly. Instead of streets winding and twisting   as they do in London, they are all regular and well planned. The streets running north and south are called "avenues" and are numbered, e.g. 1stAvenue, 2ndAvenue, etc. The streets going east and west are called "streets" and are also numbered, e.g. 51stStreet, 63rdStreet. It is all much more logical   than London's street names. But I couldn't help thinking how much more interesting than these dull cold numbers are London's illogical but colorful names of streets, e.g. "Bishopgate" (which is not a gate and hasn't a Bishop in it); "Haymarket" or "Corn market" (where you won't see any hey or corn) or "Poultry" (without a living chicken anywhere in sight) or "Thread needle Street" (where you won't find little girls learning to sew). The names of streets both in London and New York   _  . A) are quite good B) are interesting C) are not practical D) differ greatly in form

"When studying foreign speech, don't forget about body language," Anne Merritt said. Something as simple as a smile can show friendliness in one culture, embarrassment in another, impatience in a third. Even silence means different things in different places. If you want to avoid making some mistakes when traveling abroad, you should pay attention to the following.  Touch Britain, along with much of Northern Europe and the Far East, has a "non-contact" culture. In those countries, there is very little physical contact  in people's daily talks. Even brushing someone's arm by accident is the reason for an apology. However, in the high-contact cultures of the Middle East, Latin America, and southern Europe, physical touch is a big part of daily life. What's more, there are different standards for who touches whom and where. In much of the Arab world, men hold hands and kiss each other in greeting, but would never do the same with a woman. In Thailand and Laos, it is taboo  to touch anyone's head, even children's. In South Korea, elders can touch younger people with force when trying to get through a crowd, but younger people can't do the same. Eye contact In most Western countries, frequent eye contact is a sign of confidence and attentiveness . We may think that a conversation partner who looks away is either not listening to us or lying. Of course, this is not the standard around the world. In many Asian, African, and Latin American countries, the unbroken  eye contact would be considered impolite and rude. These cultures consider avoiding eye contact a sign of respect for bosses and elders. In these parts of the world, children won't look at an adult who is speaking to them, and nor will employees look at their bosses. In southern Europe, physical touch is_. A) unnecessary B) impolite C) dangerous D) common
