四六级考试

【单选题】Questions 52 to 56 are based on the following passage.
Our government recently has focused on the importance of investment in clean energy and energy efficiency as the best way to sustain ably growAmerica’s dying economy, and President Obama has called for the creation of a high-speed rail system as a way to generate green jobs, enhance economic productivity and reduce carbon emissions. The White House has announced the awarding of $ 8 billion in stimulus funding to kick-start high-speed-rail projects and improve service in 13 corridors across the country.
That’s a nice move, butAmerica’s antiquated (旧式的，过去的) rail system will have to advance a long way just to make it to the present, let alone the future. U. S. intercity railroads are a laughingstock compared with those in most other developed nations.
Today you can travel the 250 miles from Paris to Lyon on the high-speed TGV in two hours.Covering a similar distance from Philadelphia toBoston takes some five hours. and that’s on anAmtrakAcela train, the closest thing the U.S. has to high-speed rail. "Every other major industrialized nation has recognized that high-speed rail is key to economic growth and mobility," says Petra Todorovich, director of theAmerica 2050 program at the Regional PlanningAssociation. "It’s time forAmerica to realize that as well."
But whatever the public’s vision of a sparkling new 150-m. p. h. bullet train like those in Japan andEurope, the reality is that not all, or even most, of the stimulus money will go toward creating entirely new rail service. Instead, much of the initial funding will be spent improving and speeding up existing service.
Still, the initial round of $ 8 billion is just a tiny percentage of what it would cost to significantly overhaul(彻底革新) the country’s rail system.And there are concerns that by spreading the funds to so many different projects in so many different states, it won’t be possible to make a real difference in any one place, It doesn’t help that the one region that could most obviously benefit from truly high-speed rail--theBoston-to Washington corridor-received a mere $112million in funding, in part because building new track in the congested area would be prohibitively expensive and politically challenging.
Nevertheless, high-speed rail is an idea whose time has come---at least for environmentalists.According toEnvironmentAmerica, high-speed rail uses a third less energy per mile than auto or air travel, and a nationwide system could reduce oil use by 125 million bbl. a year. In addition, high speed rail represents the kind of long-term infrastructure investment that will pay back for decades. "This is a down payment on a truly national program," said Petra, "It will change the way we travel and change the way we work and live.\
What will the $ 8 billion funding mainly be invested inA．Sparkling new high-speed bullet trains.
B．Creating entirely new railroad service.
C．Modifying the existing railroad service.
D．Helping regions that might most benefit from the rail.

[答案详解] 根据题干关键词$8 billion．mainly invested in定位到原文第四段第一、二句：…the reality is that not all, or even most, of the stimulus money will go toward creating entirely new rail service. Instead, much of the initial funding will be spent improving and speeding up existing service.可知，并不是全部的，甚至也不是大部分的刺激资金将用于建设全新的铁路运输。与此相反，很多启动资金将被用于改善和提速现有的铁路运输，故选C)项。C)项中的modifying the existing railroads service是原文improving and speeding up existing service的同义转述。 [避错点拨] A)项“崭新的高速子弹头火车”、B）项“创建全新的铁路服务系统”和D)项“帮助最能够从铁路中受益的地区”都不是这80亿美元的主要投资用途。 document.getElementById("warp").style.display="none"; document.getElementById("content").style.display="block"; 查看试题解析出处>>
