问题     Olivia Pedersen thought the Nissan Leaf parked outside her favorite lunch spot near Emory University, must be hers. But she could not open the door. Nor could she open the door of the identical Leaf behind it. Cautiously, she tried the third Leaf in line and happily drove away. More than 14,000 electric vehicles are now registered in Georgia: California is the only state with more. But the juicy state incentives for buying them are coming under attack.
    Residents can claim an income-tax credit for 20% of the cost of leasing or purchasing an electric vehicle, up to $ 5,000. Combined with a possible federal tax incentive worth $ 7,500, smart Georgians are driving all the way to the bank in nearly-free electric cars. Nissan sells more of its Leaf models in Atlanta than in any other city, according to Don Francis from Clean Cities—Georgia, which promotes the use of cars like these.
    Such trends motivated Chuck Martin, a representative in Georgia’s House, to sponsor a bill to end state incentives for electric vehicles. He argues that the income-tax credit costs too much—about $ 13.6m in 2013—and that only urban types benefit from these sorts of cars. Mr. Martin’s bill was voted down in committee in February, but seems to be still breathing. Another House bill, mostly to finance transport projects, would reduce the credits: it is now before the Senate.
    Fans of electric vehicles say Georgia now leads the country in clean transport. Local power companies have helped by offering off-peak prices of 1.3 cents per kilowatt hour for charging the cars at night. And the sales tax collected on this power stays in the state, whereas cash spent on petrol largely goes elsewhere, says Jeff Cohen, founder of the Atlanta Electric Vehicle Development Coalition.
    Cutting the credits altogether might also harm Georgia in other ways. A study by Keybridge Public Policy Economics, says the state could lose $ 252m by 2030 if they disappear and people buy gas-guzzlers(耗油量大的汽车)instead. That is because drivers will spend $ 714m on petrol to get around(in contrast with the $261m they would have paid in electricity bills), and will no longer waste their savings from the federal electric-vehicle tax credit in Georgia’s shops. But the state’s incentives may be safe in the legislature after all: the president of the Senate drives an electric car himself.
What’s the main point of this passage?

选项 A、There will be more electric vehicles on road in the future.
B、Georgia’s breaks for electric vehicles may be too good to last.
C、Residents will benefit from lower taxes on electric vehicles.
D、Electric vehicles will be replaced by individual gas-guzzlers.

答案B

解析 主旨大意题。本题考查全文的主旨大意。文章开篇以奥利薇亚·裴德森的例子表明乔治亚州的电动汽车很多,并指出,州政府提供的购买电动汽车的丰厚奖励将受到打击。接着提到马丁支持一项终结该州对电动汽车的激励政策的法案。由此可知,本文主要描述了乔治亚州对电动汽车的激励政策可能受到挑战。B)是对本文大意的最好概括,故为答案。A)“将来道路上会有更多的电动汽车”,原文未提及,属于无中生有,故排除;C)“居民将从电动汽车的低税率中获益”,属于以偏概全,不能全面涵盖全文的主旨,故排除;原文最后一段第二句提到,键桥公共政策经济学的一项研究表明,到2030年,如果电动汽车消失,人们转而购买“油老虎”,这只是一种假设,D)“电动汽车将被个人的‘油老虎’代替”过于肯定,是对本句的错误理解,故排除。
