1、大学六级-265 及答案解析(总分：703.00，做题时间：90 分钟)一、BPart Writing(总题数：1，分数：106.00)1.许多人认为电子邮件将会取代传统书信2也有人对此持不同意见3你的观点BWill E-mail Replace Hand-written Letter?/B_（分数：106.00）_二、BPart Reading (总题数：1，分数：70.00)BElectric Vehicles Are Charging Up The Automotive Industry/BNext time youre filling up the cavernous fuel tan

2、k of the gas-gulping family jalopy, imagine getting 230 miles per gallon. Better yet, how about never buying another gallon of gas? After years o hope and hype, electron-powered driving finally appears to be on the verge of reality. In the next three years, at least a dozen pure electric or plug-in

3、hybrid cars are slated to hit the market in the U. S. Electricity-driven vehicles from giants such as General Motors Co. and Nissan Motor Co., as well as start-ups like Fisker Automotive Inc. in Irvine, will provide consumers with a wide variety of choices. These new vehicles promise to combine blin

4、ding fuel efficiency, radical new technology and futuristic styling that makes the hybrid Toyota Prius look downright staid.Battery makers and automakers alike are tooling up factories to produce big volumes of electric vehicles. Meanwhile, power utilities and regulators are scrambling to figure out

5、 just how big the market will be. “This is happening and its happening soon,“ said Mark Duvall, director of electric transportation at the Electric Power Research Institute, an independent, nonprofit research group. “By the end of 2011, consumers will have more choices in vehicles they can plug in t

6、han they currently do for hybrids. The electric vehicles will be arriving at a good time. With gasoline prices creeping up once again and federal regulations calling for huge fuel economy gains in the next half-decade, theres increasing demand for cars that burn less fuel, make less noise and push a

7、utomotive technology forward. In August, President Obama set a national goal o getting I million plug-in vehicles on the road by 2015. It took about twice as long to get a million hybrids rolling on U.S. streets and highways.But any new technology that involves high-voltage, exotic battery chemistri

8、es and 3,500-pound objects hurtling forward at high speed is bound to hit some potholes. Early adopters, experts say, will have to contend with charging infrastructure challenges and some pretty long waiting lists. And did we mention price? Even the least expensive electric or plug-in car will cost

9、more than $25,000, and most will come in closer to twice that. “There will be some real challenges at first,“ said Roland Hwang, vehicle policy director at the Natural Resources Defense Council. “These are going to cost more than conventional cars. The infrastructure is not going to take care of its

10、elf. These issues will determine whether this is a trickle or a massive flood.“Restarting electricsElectric cars are hardly new. In fact, a century ago, around .the time of the dawn of the automobile, there were as many electric as gasoline-powered cars. But technological limitations eventually kill

11、ed those early EV, and electric cars didnt truly raise their heads again until the late 1990s. Thats when a smattering of electrics, including the much-lamented GM EV1, was made available in California as part of a government-mandated test program. Wildly popular among a select group of enthusiasts,

12、 they were officially declared unfeasible and unprofitable by automakers. Today, only a few hundred are still on the road, among them a Toyota RAV4 EV driven by Paul Scott, co-founder of electric vehicle activist group Plug In America.Nobody was happier than Scott when Tesla Motors Inc a San Carlos,

13、 Calif. , automaker, last year began selling its all-electric Roadster, a rocket of a two-seater that noiselessly goes from zero to 60 mph in less than four seconds. True, the Roadster costs $109,000. And it has a waiting list longer than Sunset Boulevard. But to people like Scott, its arrival signa

14、led the coming of a new electric era.“This time electric cars are here to stay,“ said Scott, who envisions charging cars using solar power, making them essentially cost-free to operate. Tesla and other nimble start-ups have helped jump-start the industry. Now big automakers are getting their electri

15、c programs in gear. Thats no minor development considering the titanic capital costs involved in developing high-volume-production vehicles.For Ford Motor Co. , better batteries were key. Previous technologies were just too heavy and inefficient, said Nancy Gioia, the automakers director of global e

16、lectrification. “They werent ready for mass production,“ she said.But in the last couple of years, huge improvements and new battery chemistries “opened the opportunity“ for ambitious product plans, she said. Gioia predicts that as many as a quarter of new vehicles sold by 2020 will be electrics, pl

17、ug-in hybrids or traditional hybrids.Challenges aheadYet even the fiercest electric advocates admit that battery reliability still has room for improvement. Arthur Krieger, a retired police officer in Los Angeles, drives a Prius powered by a relatively small nickel metal hydride battery to assist th

18、e gasoline engine. Tile battery needed replacement after nine years on the road. Thats when Krieger got a nasty surprise: A new one would cost more than $ 4,800. “That cost will wipe out the entire cost savings of having a hybrid in the first place.“ Krieger said. The price would be even higher on a

19、n all-electric vehicle using the latest chemistry., lithium ion.Already widely used in cell phones, watches and laptops, those batteries have storage, charging and weight characteristics that make them superior to previous technologieswith premium prices to match. A replacement battery for a Tesla R

20、oadster costs $ 30,000, and it can move the car only 200 or so miles before it needs to be recharged. Thats a 3.5-hour process on a high-powered charger, 30 hours on regular household current.Then there is the matter of exactly where to re-juice all those electrics. Some experts believe that public

21、charging stations will be the best solution, either those put up by state and local governments or, perhaps, private for-profit companies. At present there is almost no such infrastructure. Building a nationwide network would cost tens of billions of dollars. That means most electric owners will be

22、charging at home initially. Plugin hybrids, which primarily run on batteries but also have gasoline-powered engines to supplement range and power, can get by on standard household current. Theyre ready to roll in five or six hours. All-electric cars, however, can take well over a day to charge unles

23、s owners invest thousands of dollars in home electrical upgrades.A rewarding experienceFor those willing (and able) to take the plunge, however, the rewards of owning electrified cars could include the financial kind. Thanks to a provision in last years $ 700-billion Wall Street bailout legislation,

24、 buyers of electric or plug-in hybrid cars can qualify for a tax credit of as much as $ 7,500. Routine maintenance could be a bargain too. Since these vehicles use simple electric motors rather than complex gasoline or diesel engines, as well as pared-down or in some cases nonexistent transmissions,

25、 they are far easier to service than conventional vehicles. Theres no oil to change, no radiator to flush. There are other perks as well. In California, electric vehicles still qualify for special stickers that permit their drivers to travel solo in the states carpool lanes. The stickers expire in 2

26、011, but lawmakers are considering extending the privilege until 2016. Its unclear whether plug-in hybrids will qualify.With all the excitement brewing over electric vehicles, its easy to forget that 98 of the cars sold in America still have traditional drive trains. Simply put, the gasoline engine

27、isnt going to disappear overnight. Even the most vociferous boosters of plug-in vehicles admit that the greater range and lower cost of internal combustion-powered cars and trucks mean theyll dominate vehicle sales for at least another decade or two. And for some applications, like hauling a trailer
