Part Ⅱ Reading Comprehension (Skimming and Scanning)

Directions: In this part, you will have 15 minutes to go over the passage quickly and answer the questions on Answer Sheet 1. For questions 1-7, choose the best answer from the four choices marked A, B, C and D. For questions 8-10, complete the sentences with the information given in the passage.

Electric Vehicles Are Charging Up The Automotive Industry

Next time you're filling up the cavernous fuel tank of the gas-gulping family jalopy, imagine getting 230 miles per gallon. Better yet, how about never buying another gallon of gas? After years of 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 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 blinding 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 just how big the market will be. "This is happening and it's 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 than 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, there's increasing demand for cars that burn less fuel, make less noise and push automotive 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 chemistries 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 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 itself. These issues will determine whether this is a trickle or a massive flood."

Restarting electrics

Electric 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 killed those early EV, and electric cars didn't truly raise their heads again until the late 1990s. That's 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, 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, Calif. , automaker, last year began sellin

A．appear to be in the market.

B．tend to replace fuel vehicles.

C．offer a wide range of choices.

D．appear to be on the verge of success.
