{{B}}Directions:{{/B}}
Read the following text carefully and then translate the underlined segments intoChinese. Your translation should be written neatly onANSWER SHEET 2.
Once the exclusive domain of executives with expense accounts, mobile phones are set to become one of the central technologies of the 21st century. (46) {{U}}Within a few years, the mobile phone will evolve from a voice-only device to a multi-functional communicator capable of transmitting and receiving not only sound, but video, still images, data and text. {{/U}}A、whole new era of personal communication is on the way.
Thanks in part to the growth of wireless networks, the telephone is converging with the personal computer and the television. (47) {{U}}Soon light-weight phones outfitted with high resolution screens--which can be embedded in everything from wristwatches to palm-held units will be connected to series of low orbit satellites enabling people to talk, send and receiveE-mail, or take part in video conferences anytime, anywhere. {{/U}}These phones might also absorb many of the key functions of the desktop computer. Mobile devices are expected to be ideal for some of the new personalized services that are becoming available via the Internet.
The communications revolution is already taking shape around the globe. InEurope, mall-scale trials are under way using mobile phones for electronic commerce. For example, most phones contain a subscriber identification module (SIM) card that serves primarily to identify a user to the phone network. Some manufacturers plan to upgrade the SIM card to an all-in-one personal identification and credit carD、Another approach is to add a slot to mobile phones for a second smart card designed specifically for mobile ecommerce. (48) {{U}}These cards could be used to make payments over the Internet or removed from the phone for use in point of-sale terminals to pay for things like public transportation, movie tickets or a round of drinks at the bar. {{/U}}
In France, Motorola is currently testing a dual slot phone, the Star TACD, in a trial with France Telecom while in Finland Nokia is testing a phone that uses a special plug in reader for a tiny smart carD、Siemens is pursuing a different approach. (49) {{U}}Since it is not very clear whether it’s best to do everything with a single device, Siemens is developing dual slot phones andEinstein, a device equipped with a smart card reader and keypad that can be linked to the phone via infrared wireless technology. {{/U}}
(50) {{U}}For those who want to, though, it will be possible to receive almost all forms of electronic communication through a single device, most likely a three-in-one phone that serves as a cordless at home, a cell phone on the road and an intercom at work. {{/U}}"The mobile phone will become increasingly multifunctional," saysBurghardt Schallenberger, vice president for technology and innovation at Siemens Information andConsumer Products.

Like street comer prophets proclaiming that tile end is near, scientists who study the earth’s atmosphere have been issuing predictions of impending doom for the past few years without offering any concrete proof. So far even the experts have had to admit that no solid evidence has emerged that this is anything but a natural phenomenon.And the uncertainty has given skeptics-especially Gingrichian politicians--plenty of ammunition to argue against taking the difficult, expensive steps required to stave off a largely hypothetical calamity.
Until now,A、draft report currently circulating on the Internet asserts that the global temperature rise can now be blamed, at least in part, on human activity. Statements like this have been made before by individual researchers-who have been criticized for going too far beyond the scientific consensus.But this report comes from the International Panel onClimateChange (IPCC、, a respected UN sponsored body made up of more than 1,300 leading climate experts from 40 nations. This shift in scientific consensus is based not so much on new data as on improvements in the complex computer models that climatologists use to test their theories. Unlike chemists or molecular biologists, climate experts have no way to do lab experiments on their specialty. So they simulate them on supercomputers and look at what happens when human generated gases-carbon dioxide from industry and auto exhaust, methane from agriculture, chlorofluoro carbons from leaky refrigerators and spray cans-are pumped into the models virtual atmospheres.
Until recently, the computer models weren’t working very well. When the scientists tried to simulate what they believe has been happening over the past century or so, the results didn’t mesh with reality; the models said the world should now he warmer than it actually is. The reason is that the computer models had been overlooking an important factor affecting global temperatures: sulfur dioxides that are produced along withCO2 when fossil fuels are burned in cars and power plants.Aerosols actually cool the planet by blocking sunlight and mask the effects of global warmning. Once the scientists factored in aerosols, their models began looking more like the real worlD、The improved performance of the simulations was demonstrated in 1991, when they successfully predicted temperature changes in the aftermath of the massive Mount Pinatubo eruption in the Philippines.A、number of studies since have added to the scientists confidence that they finally know what they are talking about-and can predict what may happen if greenhouse gases continue to be pumped into the atmosphere uncheckeD、

第10题：It was inevitable that any of President George W.Bush’s fans had to be very disappointed by his decision to implement high tariffs on steel imported to the U.S. The president’s defense was pathetic: He argued that the steel tariffs were somehow consistent with free trade, that the domestic industry was important and struggling, and that the relief was a temporary measure to allow time for restructuring. One reason that this argument is absurd is that U. S. integrated steel companies ("Big Steel") have received various forms of government protection and subsidy for more than 30 years.
Instead of encouraging the industry to restructure, the long-term protection has sustained inefficient companies and cost U.S. consumers dearly.AsAnne O. Krueger, now deputy managing director of the International Monetary Fund, said in a report onBig Steel: "TheAmericanBig Steel industry has been the champion lobbyist and seeker of protection .... It provides a key and disillusioning example of the ability to lobby in Washington for measures which hurt the general public and help a very small group."
Since 1950s,Big Steel has been reluctant to make the investments needed to match the new technologies introduced elsewhere. It agreed to high wages for its unionized labor force. Hence, the companies have difficulty in competing not only with more efficient producers inAsia andEurope but also with technologically advanced U. S. mini-mills, which rely on scrap metal as an input. Led by NucorCor. , these mills now capture about half of overall U. S. sales.
The profitability of U. S. steel companies depends also on steel prices, which, despite attempts at protection by the U.S. and other governments, are determined primarily in world markets. These prices are relatively high as recently as early 2000 but have since declined with the world recession to reach the lowest dollar values of the last 20 years.Although these low prices are unfortunate for U.S. producers, they are beneficial for the overall U. S. economy. The low prices are also signal that the inefficientBig Steel companies should go out of business even faster than they have been.
Instead of leaving or modernizing, the dyingBig Steel industry complains that foreigners dump steels by selling at low prices. However, it is hard to see why it is bad for the overall U.S. economy if foreign producers wish to sell us their goods at low prices.After all, the extreme case of dumping is one where foreigners give us their steel for free and why would that be a bad thing
Which of the following can be a disadvantage of U.S. "Big Steel" as pointed out in the textA．Lower efficiency.
B．Lack of protection.
Corporate structures.
D．Lobbyist addiction.
