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.

问答题The Kingdom of Denmark  The smallest and most southern of the Scandinavian countries, Denmark offers an interesting mix of lively cities and rural countryside, Ancient castles, ring forts, jazz festivals, the sleekest modem design you’ll ever see and the people who invented Lego-who could ask for more?  Danish Vikings once took to the seas and ravaged half of Europe, but these days they’ve forged a society that stands as a benchmark of civilization, with progressive policies, widespread tolerance and a liberal social-welfare system.  Copenhagen has been Denmark’s capital for 600 years and is the largest city in Scandinavia. It’s an appealing and largely low-rise city comprised of block after block of period six-storey buildings. Church steeples punctuate the skyline, with only a couple of modem hotels marring the view.  No matter what your interests, Copenhagen has a whole lot of sightseeing and entertained on offer. Historic or modem, sleek shops or cozy cafes-it’s all-nestled fight in the heart of a compact city and presented with typical Scandinavian assurance and flair.  Hans Christian Andersen wrote a fairly tale about her; Disney produced the movie; and Copenhagen maintains a statue in her honor, which continues to be the largest tourist attraction in Denmark and the most photographed statue in the world.  New York has the Statue of Liberty, Pads has its Eiffel Tower and Copenhagen has this pretty, charming maiden who stars dreamily out across the water, just as her Danish countrymen have done for thousands of years. The Little Mermaid is just small enough and close enough to the water to be an excellent symbol of Copenhagen and Denmark. The sculpture stands 165 centimeters tall and weighs 175 kilograms. The original one, cast in bronze, was presented to the City of Copenhagen on August 23, 1913 by Carl Jacobsen.  The Nationalmuseet (National Museum) is a mustsee for anyone who wants a comprehensive grounding in Danish history and culture. Tree to its name, it has the biggest collection of Danish historical artifacts in the country. On Sundays during summer the ambience is enhanced by free chamber music concerts. The Nationalmuseet has dibs on virtually every antiquity found on Danish soils, whether it was unearthed by a farmer ploughing his fields or a government-sponsored archaeological dig.

问答题Classes at American College  The year at an American college is divided into 2 semesters or 3 quarters. Semesters are 15 weeks; quarters are 10 weeks. American college students usually attend school from September to May. Occasionally their academic pursuits extend into the summer.  Students choose their classes a few weeks prior to the start of each term. Universities offer a great many classes in the students’ main area of study and in other areas as well. Students must take both. These include science, mathematics, computer, history and English. Other classes may be just for fun, like dance, theater or sports. Tests usually are given in the middle of the term and at the end3. The final examinations are extremely important. In some classes, the professor asks the students to write a research paper or complete a certain task instead of taking a test.  Classes usually are organized through lectures. For example, a student may attend 2 or 3 lectures a week by the professor. As many as several hundred students sit at each lecture. Sometimes they also attend a smaller class to ask questions and discuss what the professor says4. These small classes are taught by professor’s assistants. In science classes, students also have a long laboratory class each week.  What do American students study at college? The US Department of Education says the most popular area of study is sciences and management. Next is social science, which encompasses history, sociology, literature, public relations and political science. English is another popular field of study. Then comes computer science and health and life sciences like biology, chemistry and physics. Education is popular, too. Foreign languages are not popular as a main area of study among American college students. However, students at many colleges must study a language other than English before they can graduate. The most popular foreign language is Spanish, followed by French and German.

问答题金砖四国  近年来,没有哪种概念比“金砖四国”在商界和政界人士中间更流行的了。“垒砖四国”是指巴西、俄罗斯、印度、中国这四个正在崛起的庞大经济体。据认为,这些国家的实力和影响力正在改变世界经济和政治现实。然而,把这四个国家归入一类掩盖了一个简单的事实:中国和印度的崛起表明力量对比正在发生实实在在的变化,而俄罗斯和巴西经济无足轻重,支撑两国经济的是高昂的自然资源价格。这种区别意义重大。  中国、印度与俄罗斯、巴西的根本区别在于,中印两国正在同西方争夺“知识资本”:努力建设一流的大学,对高增值、技术密集型产业进行投资,利用事业有成的海外侨胞在祖国进行创业活动。例如中国立志建设100所世界一流的大学,重点在于科学技术。印度是除了美国之外信息技术产业最具活力的国家之一。中国和印度都面临诸多挑战,但两国都在采取必要措施,以实现可持续的绎济增长。
