Interviewer-------- Why is English so important?David------- Well, English is so important primarily because so many people speak it and use it, so it has now become the lingua franca in the world in a way that we’ve never seen before. We’ve never had a world language of this kind before. So people are learning it not just to be able tocommunicate with native speakers, but also with speakers of other language around world.Interviewer-------And why has it become that dominant language?David------I think the reason for that is actually very complicated, although in the twentieth century, we can just see that it’s the rise of the US military and consumer power. I mean the technology, all the big developments in technology largely came from the US. So all of these developments actually were produced within the English language, and people had to learn English in order to understand them, or to benefit from them. The Internet is only one example of that kind. Once a language has got into that position of dominance, it’s actually very different to shift it. So we could be seeing the emergence of other big languages in the world becoming more important than they have been, like Spanish, but it’s unlikely that they’re going to shift the English from its position of dominance.36.

共用题干Mobile Phones:Change Our LifeIn the case of mobile phones,change is everything. Recent research indicates that the mobile phone is changing not only our culture,but our very bodies as well.First,Let's talk about culture.The difference between the mobile phone and its parent一the fixed-line phone,is that a mobile phone corresponds to a person,while a landline goes to a place.If you call my mobile,you get me.If you call my fixed-line phone,you get whoever answers it.This has several implications.The most common one,however,and perhaps the thing that has changed our culture forever,is the"meeting"influence.People no longer need to make firm plans about when and where to meet.Twenty years ago,a Friday night would need to be arranged in advance.You needed enough time to allow everyone to get from their place of work to the first meeting place.Now,however,a night out can be arranged on the run.It is no longer"see you there at 8", but"text me around 8 and we'll see where we all are".Texting changes people as well.In their paper,"Insights into the Social and Psychological Effects of SMS Text Messaging",two British researchers distinguished between two types of mobile phone users:the"talkers"and the"texters”一those who prefer voice to text message and those who prefer text message to voice.They found that the mobile phone's individuality and privacy gave texters the ability to express a whole new outer personality.Texters were likely to report that their family would be surprised if they were to read their texts.This suggests that texting allowed texters to present a self-image that differed from the one familiar to those who knew them well.Another scientist wrote of the changes that mobiles have brought to body language.There are two kinds that people use while speaking on the phone.There is the"speakeasy":the head is held high,in a self-confident way,chatting away.And there is the"spacemaker":these people focus on themselves and keep out other people.Who can blame them?Phone meetings get cancelled or reformed and camera-phones intrude on people's privacy. So,it is understandable if your mobile makes you nervous.But perhaps you needn't worry so much.After all,it is good to talk.When a"spacemaker" is using the mobile phone,he tries to avoid other people.A:Right B:Wrong C:Not mentioned

If you don′t think a phone is the right gift for a lover, the smart choice this year is a smart phone. For people who don′t read instructions The easiest-to-use phone is the iPhone. It′s that has pushed it to the No.1 selling position, surpassing the Motorola Razr. The iPhone′s touch screen is easy to operate and it′s also easy to customize (用户化). The iPhone can run all sorts of applications such as those help you to lose weight, identify a song on the radio, find a restaurant or do many other things. For the futurist The T-Mobile G1 is very popular as it is the first phone to offer a Google browser, meaning that you′re getting the real web on your phone, but it′s the phone′s potential that qualifies it for the futurist. The exciting applications are interesting, but they don′t always work smoothly. Sometimes it is hard to use the applications it comes with. The system should improve as it becomes more popular, so it holds great promise. With few restrictions on the design of applications for the phone, the G1 could be the first phone to incorporate (整合) some of the coolest. For the road warrior The new BlackBerry Storm is something like the equivalent (等同物) of a mullet--a business up front, party in the back. It still incorporates the serious mail and organization features that have endeared (使受钟爱) these phones to business people. The 3.25-inch is bright and detailed and it′s a decent size for watching videos on the go. For the Luddite (反对技术进步的人) For those who can′t handle buttons and new features, there is the Samsung Jitterbug Dial. Some people are Luddites who just want a few large buttons to make calls. That′ s it, just calls. That makes it even easier to use an iPhone. Please explain the underlined phrase "comes with".

Text 3 The hotel guestroom telephone is being ignored more and more these days.The average hotel guest checks in with three mobile devices.That has pushed the guestroom phone down the list of preferred communication devices,"We have noticed a signiflcant decline in guestroom phone usage and that guests,by and large,bring and use their own mobile phones:'says Kevin Carl,executive vice president of Radisson Hotel Group.And why not?Hotels traditionally have charged exorbitant（过高的）prices for the privilege of using a landline.Travelers are now hanging up on the traditional phone and using the hotel room phone only for minor logistical purposes,thanks to the advent of new technologies.Kate Ashton,senior vice president of operations for Wyndham Grand,says the most common uses for in-room phones are for calls to the front desk.The most frequently asked questions are"What's the Wi-Fi password?"and"When is checkout time?"That said,hotels say they would never give up on Iandlines for the simple reason that they need them for security."Having a landline accessible means guests can always have a way to call in case of emergency or if they have any issues with their own devices,"Ashton says.That doesn't mean the guestroom telephone is not changing or that hotels aren't finding technologies to supplement the landline."Telephones continue to evolve and become more stylish in the hotel space,"says Andrea Torrance,vice president of operations for AccorHotels North and Central America.Hotel room phones used to be quite simple with one line and basic services.Now companies such as Cetis provide extensive services out of one device such as one-touch voice mail retrieval,Bluetooth paring for music streaming and digital clocks.They also have built-in USB charging ports for smarfphones."Now,the trend seems to be going backward in time to a single line corded telephone,"says Chad Collins,vice president of sales for the Americas at VTech,a company that produces hotel landlines."I believe this is driven by the fact that hotels simply want a telephone with a dial tone,not all of the bells and whistles.Guests'demands are changing,and the telephone is not excluded from those changes."But many hotels are finding other ways to communicate with guests.Roxy,a Seattle start-up,has created speech-enabled devices that will allow hotels to replace landlines with voice-activated calling.The devices also act as a guests'personal concierge.Guests can place requests to the front desk and get recommendations for restaurants and activities.Collins says there is no way a landline will compete with a mobile phone.But he believes both can serve different purposes."The idea that we are trying to compete with mobile devices is a bit misguided,"he says.31.Why is hotel guestroom telephone being ignored?A.Because each hotel guest has three mobile devices.B.Because hotel guests prefer to use mobile devices.C.Because hotel guestroom telephone is not safe enough.D.Because guests have easy access to mobile devices.

问答题The tiny Isle of Man in the Irish Sea is not known as a vanguard of technology, but this month it was to serve as the test bed for the highly acclaimed third-generation mobile phones. A subsidiary of British Telecom (BT), the British phone company, cobbled together a network and prepared to hand out prototype mobile handsets to about 200 volunteers. But problems arose in the software that keeps track of each call as it moves from one tower’s range to another’s. BT postponed the trial until late summer, after a similar delay announced a few weeks earlier by NTT DoCoMo in Japan. What’s the big deal? Aren’t thousands of mobile calls “handed off” every day from one “cell” to another without a glitch? They are indeed. But third-generation technology, or 3G, is so radically new that it requires a rethinking of just about every aspect of how mobile phones work, from the handset to the transmission masts to the software that runs them. For this reason, 3G are a massive engineering and construction project that will take years to complete and cost hundreds of billions of dollars. The magnitude of this effort has somehow been forgotten in the mad scramble to be first out. The handover problem is a case in point. When you talk on a conventional mobile phone, your call is beamed as a continuous stream of digital data to the nearest receiver. The technology for handing these calls off from one area to the next was worked out years ago. But a 3G phone is different it bundle up the data into little packets and sends them through the airwaves, one at a time. This creates the impression of an Internet connection’s being”always on,” which is good news. But keeping rack of these data bundles from one region to the next is a daunting engineering problem — and, more to the point, a brand-new one. NEC, the Japanese phone company that supplies BT with equipment for its Isle of Man trail, hasn’t had time to work it out. Handset makers also have work to do. The 3G technologies have so many features; only a wonder gizmo could handle all of them, which is why none exists. The phones are not only supposed to work with 3G networks but also with the less sophisticated ( but cheaper and more useful) General Packet Radio Service (GPRS) technology already being installed on the continent and also with the current mobile phone standard, Global System for Mobile (GSM). Phones for corporate executives are also supposed to adapt to dozens of other standards around the world. Doing all this requires powerful, custom-built computer chips, which are tough to make quickly. A device that does so many things is bound to guzzle a lot of power. Prototype 3G phones drain so much juice that they’ve been known to get uncomfortably hot. Batteries that can keep a conventional phone running for days would fizzle in a 3G handset in a matter of minutes. Engineers are searching for alternative, but at the moment the lack of a long-lasting battery is a major hurdle. None of these problems is insurmountable, but neither will they be resolved quickly. Analysts at Forrester Research in the Netherlands predict that even in 2005, when more than half of Europe’s phones will be connected to the Internet, fewer than 15 percent of them will use 3G. That’s a measure of this technology’s complexity and immaturity.
