问题     If there is any endeavour whose fruits should be freely available, that endeavour is surely publicly financed science. Morally, taxpayers who wish to should be able to read about it without further expense. And science advances through cross-fertilisation between projects. Barriers to that exchange slow it down.
    There is a widespread feeling that the journal publishers who have mediated this exchange for the past century or more are becoming an impediment to it. One of the latest converts is the British government. On July 16th it announced that, from 2013, the results of taxpayer-financed research would be available, free and online, for anyone to read and redistribute. Britain’s government is not alone. On July 17th the European Union followed suit. It proposes making research paid for by its next scientific-spending round which runs from 2014 to 2020, and will hand out about ¢80 billion, in grants similarly easy to get hold of. In America, the National Institutes of Health has required open-access publishing since 2008.
    Criticism of journal publishers usually boils down to two things. One is that their processes take months, when the internet could allow them to take days. The other is that because each paper is like a mini-monopoly, which workers in the field have to read if they are to advance their own research, there is no incentive to keep the price down. The publishers thus have scientists—or, more accurately, their universities, which pay the subscriptions—in an armlock. That leads to generous returns. In 2011 Elsevier, a large Dutch puhlisher, made a profit of £768m on revenues of £2. 06 billion—a margin of 37%. Indeed, Elsevier’s profits are thought so egregious by many people that 12,000 researchers have signed up to a boycott of the company’s journals.
    Publishers do provide a service. They organise peer review, in which papers are criticised anonymously by experts. And they sort the scientific sheep from the goats, by deciding what gets published, and where. That gives the publishers huge power. Since researchers, administrators and grant-awarding bodies all take note of which work has got through this filtering mechanism, the competition to publish in the best journals is intense, and the system becomes self-reinforcing, increasing the value of those journals still further.
    But not, perhaps, for much longer. Support has been swelling for open-access scientific publishing: doing it online, in a way that allows anyone to read papers free of charge. The movement started among scientists themselves, but governments are now, as Britain’s announcement makes clear, paying attention and asking whether they, too, might benefit from the change. A revolution, then, has begun. Technology permits it; researchers and politicians want it If scientific publishers are not trembling in their boots, they should be.
According to Paragraph 1, the author holds that______.

选项 A、fruits of science should be freely accessible to the public
B、nonscientists should pay for reading about science advances
C、collaboration among researchers is essential to science
D、hindering exchange of ideas equals blocking scientific progress

答案D

解析 第一段作者指出“纳税人应能够免费获取公共资助的科研成果”,并指出主要原因:科学通过科研项目间的交流而得以进步,阻碍这种交流会使科学发展减慢。可见,作者认为阻碍思想交流就会阻碍科学进步,[D]选项正确。
