问题    When George W. Bush delivered his State of the Union Address this past January, three words appeared that had not previously been heard from the Oval Office: Switchgrass, stalks and woodchips.
    Bush’s signals on renewable energy have been decidedly mixed. Shortly before he visited the National Renewable Energy Laboratory (NREL) in Colorado last February, a $5 million funding shortfall forced the lab to lay off 32 workers. Bush blamed the layoffs, and NREL got its funding back.
    Switchgrass is a fast-growing perennial plant native to the central and eastern U.S. and tolerant of many different soil types. To make cellulosic ethanol, switchgrass -- or any cellulose-based plant -- is broken down to make sugar, then fermented to make the fuel. Supporters say that when blended with petroleum products, ethanol from switchgrass results in a net energy gain of 334 percent, compared to just 21 percent for corn- based ethanol.
    The cellulosic process has been invented and is being refined, but it hasn’t been commercialized, and that’ s what is preventing it from going into our tanks today, says former CIA Director James Woolsey, among switchgrass’ s biggest supporters.
Corn-based ethanol has made great strides. According to Tom Slunecka, executive director of the Ethanol Promotion and Information Council, the U.S. currently produces four billion gallons a year, or approximately three to four percent of the fuel supply. "It’ s growing rapidly," he says. "By 2012 we’ re projecting 7.5 billion gallons, but I think we’ 11 far surpass that." Automakers get federal tax credits for producing "bi-fuel" cars and trucks that can nm on ethanol, but until recently the lack of an ethanol refueling infrastructure (永久性设施) obstructed the actual use of the fuel. But now General Motors and other carmakers are promoting ethaonol vehicles with a new vigor. Even without bi-fuel technology, all cars today can burn a 10 percent ethanol blend
Slunecka says biobased ethanol production is still in its infancy: He cites a Canadian plant currenty producing 100,000 gallons per year. "It works, it’ s not science down the road," he says. "Private companies m trying to crack the cost barrier. But the feedstock potential is enormous. I can’ t wait until these cellulosic plants are bolted onto the front side of traditional ethanol plants."
    David Bransby, a professor in Auburn University’ s Agronomy Department, says we need to take action because we’ re in an international competition. "Europe is ahead of everybody in the use of biodiesel, and Brazil! is leading the world in the production and use of ethanol. We are behind. I hope that the President’ s address indicates that there is going to be a change, but he’ s fighting a war in Iraq and trying to recover from two, hurricanes. To be quite honest, these alternative fuels are just as important as those other things. It’s all part o national security and needs to be treated with the same priority."
From paragraph two, we can infer that ______.
选项 A、Bush forced the National Renewable Energy Laboratory to lay off workers
B、Bush visited the lab (NREL  before the laid-off of 32 workers
C、the 32 workers might be reemployed after Bush’ s visit
D、Bush carried $ 5 million cash to the NREL when he visited there
答案C
解析 细节推理题。本题考查对第二段的理解。该段段首句首先点明，布什总统对可再生能源的表态信号是多重的(mixed 。该句起着承上启下的作用，因为第一段表明他在国情咨文里首次用了switch grass等词，而第二段则表明，布什到了国家再生能源实验室去了后，五百万的拖欠资金就到位了。言外之意，那些因为资金不足而被解雇的32名工人说不定又披重新雇佣，因此，答案选C 。解雇工人不是布什的意愿，因此A 惜，布什在解雇发生不久后去了实验室，因此B 错，文中没有提到现金，因此，D 项无法被推理得出。因此，答案只有选C 正确
