Not Any More Science fiction has often been the source of inspiration for new technologies. The exoskeletons and head-mounted displays featured in the film “Aliens“, for e
28、xample, spawned a number of militaryfunded projects to try to create similar technologies. Automatic sliding doors might never have become popular had they not appeared on the television series “Star Trek“. And the popularity of flip-top or “clamshell“ mobile phones may stem from the desire to look
29、like Captain Kirk flipping open his communicator on the same program. Now it seems that “Star Trek“ has done it again. This month, American soldiers in Iraq will begin trials of a device inspired by the “comm badge“ featured in “Star Trek: The Next Generation“. Like crew members of the starship Ente
30、rprise, soldiers will be able to talk to other members of their unit just by tapping and then speaking into a small badge worn on the chest. What sets the comm badge apart from a mere walkie-talkie, and appeals to “Star Trek“ fans, is the systems apparent intelligence. It works out who you are calli
31、ng from spoken commands, and connects you instantly. The system, developed by Vocera Communications of Cupertino, California, uses a combination of Wi-Fi wireless networking and Voice-overInternet Protocol (VoIP) technologies to link up the badges via a central server, akin to a switchboard. The bad
32、ges are already being used in 80 large institutions, most of them hospitals, to replace overhead paging systems, says Brent Lang, Voceras vice-president. Like its science-fiction counterpart, the badge is designed so that all functions can be carded out by pressing a single button. On pressing it, t
33、he caller gives a command and specifies the name of a person or group of people, such as “call Dr. Smith“ or “locate the nearest anesthesiologist“. Voice-recognition software interprets the commands and locates the appropriate person or group, based on whichever Wi-Fi base-station they are closest t
34、o. The person receiving the call then hears an audible alert stating the name of the caller and, if he or she wishes to take the call, responds by tapping the badge and starting to speak. That highlights a key difference between the “Star Trek“ comm badge and the real-life version: A Voceras impleme
35、ntation allows people to reject incoming calls, rather than having the voice of the caller patched through automatically. B But even the most purist fans can forgive Vocera for deviating from the script in this way, says David Batchelor, an astrophysicist and “Star Trek“ enthusiast at NASAs Goddard
36、Space Flight Center in Greenbelt, Maryland. C For there are, he notes, some curious aspects to the behavior of the comm badges in “Star Trek“. D When the captain of the Enterprise says “Picard to sick-bay: Medical emergency on the bridge“, for example, his badge somehow connects him to the sick-bay
37、before he has stated the destination of the call. Allowing badge users to reject incoming calls if they are busy, rather than being connected instantly, was a feature added at the request of customers, says Mr. Lang. But in almost all other respects the badges work just like their fictional counterp
38、arts. This is not very surprising, says Lawrence Krauss, an astrophysicist at Case Western Reserve University in Cleveland, Ohio, and the author of “The Physics of Star Trek“. In science fiction, and particularly in “Star Trek“, most problems have technological fixes. Sometimes, it seems, those fixe
39、s can be applied to real-world problems too. Voceras system is particularly well suited to hospitals, says Christine Tarver, a clinical manager at E1 Camino Hospital in Mountain View, California. It allows clinical staff to reach each other far more quickly than with beepers and overhead pagers. A r
40、ecent study carried out at St. Agnes Healthcare in Baltimore, Maryland, assessed the amount of time spent by clinical staff trying to get hold of each other, both before and after the installation of the Vocera system. It concluded that the badges would save the staff a total of 3,400 hours each yea
41、r. Nursing staff often end up playing phone tag with doctors, which wastes valuable time, says Ms Tamer. And although people using the badges sometimes look as though they are talking to themselves, she says, many doctors prefer it because it enables them to deal with queries more efficiently. The s
42、ystem can also forward calls to mobile phones; it can be individually trained to ensure that it understands users with strong accents; and it can even be configured with personalized ring tones. In Iraq, soldiers will use the Vocera badges in conjunction with base-stations mounted on Humvee armored
43、vehicles. Beyond medical and military uses, Vocera hopes to sell the technology to retailers and hotels. And the firms engineers are now extending the system to enable the badges to retrieve stored information, such as patient records or information about a particular drag, in response to spoken com
44、mands. Their inspiration? Yet another “Star Trek“ technology: the ships talking, ships computer. 35 According to the passage, through which of the following, new technologies are often the results of the inspirations? （ A） science fiction. （ B） personalized ring tones. （ C） Star Trek fans. （ D） Voce

46、s widely used in Iraq for war purposes. （ C） Comm badge is an intelligent new device of voice-driven wireless communication. （ D） Comm badge is a mere walkietalkie that appeals to “Star Trek“ fans. 38 The word intelligence in paragraph 2 is closest in meaning to （ A） faculty. （ B） news. （ C） informa
47、tion. （ D） command. 39 According to paragraph 4, the word it refers to （ A） a person. （ B） a single button. （ C） science-fiction. （ D） the badge. 40 Which of the following statements is INCORRECT about the voice badges? （ A） All functions can be carded out by pressing a single button. （ B） The devic

49、n. （ A） It is able to predict the future. （ B） It allows people to reject incoming calls. （ C） It works out who you are calling from spoken commands. （ D） Its very easy to use. 42 Which of the following features of the Vocera system are not mentioned in the passage? （ A） It can forward calls to mobile phones. （ B） It can be trained to understand users with strong accents. （ C） It can have wireless access to the internet. （ D） It can be used to photograph at night. 43 Which of the following would be not very likely to use the new communicating techno
