问题     It seemed so promising—mirrors sprawled across desert land in the scorching southwest delivering clean electricity and helping Americans out of the increasing fuel crisis. Some scientists and industry developers claim that Nevada’s empty and sun-drenched expanses alone could supply enough electricity to power the entire country.
    Now even the optimists fear this wonderful prospect may be a mirage. Congress cannot make up their mind to extend the tax-reducing bill for solar-energy projects, which solar advocates say is critical to the future of their industry but which is due to expire at the end of the year. The latest attempt failed in the Senate earlier this month, prospects for a deal before November’s presidential and congressional elections now look dim. Uncertainty has led some investors to delay or abandon projects in the past few months.  Rhone Resch, the president of the Solar Energy Industries Association, said if the tax-reducing bill is allowed to expire at the end of the year, "it will result in the loss of billions of dollars in new investments in solar. "
    Further dampening hopes for a big solar-energy boom, the federal Bureau of Land Management (BLM) has abruptly suspended new applications to put solar collectors on federal land. The agency says it has received more than 130 applications and needs to conduct a region-wide environmental impact study on the industry before it will accept any more.  The study will take 22 months to complete, however. Few argue against trying to preserve precious water sources and protect desert tortoises and other creatures that might not enjoy cohabiting with sprawling fields of mirrors. But many solar advocates wonder why the government is not acting as cautiously when it comes to drilling for oil and gas.
    Senator Maria Cantwell, a Democrat from Washington State, wants a congressional probe into the proposed suspension. "The fact that the BLM pops this out without people even knowing about it, especially when solar thermal looks extremely promising as a power source, is not right," she says. Harry Reid of Nevada, who is the majority leader in the Senate, also condemns the BLM’s freeze, saying that it could "slow new development to a crawl".
    The BLM is not without its supporters, however. At a public meeting on June 23rd in Golden, Colorado, Alex Daue, of the Wilderness Society, said that his organization supports renewable energy development as long as it doesn’t damage other important resources. The message is clear: no rubber stamps, even for renewable energy.
Which of the following titles is closest to the message the text tries to convey?

选项 A、Renewable Energy
B、A heavy Blow for Solar Energy
C、Environment and Solar Energy
D、Do We Need Solar Energy?

答案B

解析 本文由一幅未来场景引出问题,即太阳能面临挑战,随后分别论述了正反观点。作者在论述完两种观点之后,并未明确给出自己的观点,甚至未做出总结,这就充分说明本文的重点不在于正反观点,而在于论述事实,即问题才是本文的核心。另外从篇幅上我们也可以看出一些端倪:本文一共五段,而对问题的论述就占了两段,第一段的引子也是为问题的提出作铺垫,这样算起来就共三段,足以说明本文的重点在于论述问题。第二段论述了太阳能免税法案无法延长,第三段论述了BLM中止了受理太阳能项目申请。所以全文的核心都是围绕太阳能遭受的打击,选项B正好表达了这个意思,因此是正确答案。
