2011年12月大学英语六级真题及答案Part II Reading Comprehension (Skimming and Scanning) (15 minutes)Google's Plan for World's Biggest Online Library: Philanthropy Or Act of Piracy?In recent years, teams of workers dispatched by Google have been working hard to make digital copies of books. So far, Google has scanned more than 10 million titles from libraries in America and Europe - including half a million volumes held by the Bodleian in Oxford. The exact method it uses is unclear; the company does not allow outsiders to observe the process.Why is Google undertaking such a venture? Why is it even interested in all those out-of-printlibrary books, most of which have been gathering dust on forgotten shelves for decades? Thecompany claims its motives are essentially public-spirited. Its overall mission, after all, is to "organise the world's information", so it would be odd if that information did not include books.The company likes to present itself as having lofty aspirations. "This really isn't about making money. We are doing this for the good of society." As Santiago de la Mora, head of Google Books for Europe, puts it: "By making it possible to search the millions of books that exist today, we hope to expand the frontiers of human knowledge."Dan Clancy, the chief architect of Google Books, does seem genuine in his conviction that thisis primarilya philanthropic (慈善的) exercise. "Google's core business is search and find, soobviously what helps improve Google's search engine is good for Google," he says. "But we havenever built a spreadsheet (电子数据表) outlining the financial benefits of this, and I have neverhad to justify the amount I am spending to the company's founders."It is easy, talking to Clancy and his colleagues, to be swept along by their missionary passion. But Google'sbook-scanning project is proving controversial. Several opponents have recently emerged, ranging from rival tech giants such as Microsoft and Amazon to small bodies representing authors and publishers across the world. In broad terms, these opponents have levelled two sets of criticisms at Google.First, they have questioned whether the primary responsibility for digitally archiving the world's books should be allowed to fall to a commercial company. In a recent essay in the New YorkReview of Books, Robert Darnton, the head of Harvard University's library, argued that because such books are a common resource – the possession of us all – only public, not-for-profit bodiesshould be given the power to control them.The second related criticism is that Google's scanning of books is actually illegal. This allegation has led to Google becoming mired in (陷入) a legal battle whose scope and complexity makes the Jarndyce and Jarndyce case in Charles Dickens' Bleak House look straightforward.At its centre, however, is one simple issue: that of copyright. The inconvenient fact about most books, to which Google has arguably paid insufficient attention, is that they are protected by copyright. Copyright laws differ from country to country, but in general protection extends for the duration of an author's life and for a substantial period afterwards, thus allowing the author's heirs to benefit. (In Britain and America, this post-death period is 70 years.) This means, of course, that almost all of the books published in the 20th century are still under copyright – and the last century saw more books published than in all previous centuries combined. Of the roughly 40 million books in US libraries, for example, an estimated 32 million are in copyright. Of these, some 27 million are out of print.Outside the US, Google has made sure only to scan books that are out of copyright and thus in the "public domain" (works such as the Bodleian's first edition of Middlemarch, which anyone canread for free on Google Books Search). But, within the US, the company has scanned both in-copyright and out-of-copyright works. Inits defence, Google points out that it displays only small segments of books that are in copyright– arguing that such displays are "fair use". But critics allege that by making electronic copies of these books without first seeking the permission of copyright holders, Google has committed piracy."The key principle of copyright law has always been that works can be copied only once authors have expressly given their permission," says Piers Blofeld, of the Sheil Land literary agency in London. "Google has reversed this – it has simply copied all these works without bothering toask."In 2005, the Authors Guild of America, together with a group of US publishers, launched a class action suit (集团诉讼) against Google that, after more than two years of negotiation, endedwith an announcement last October that Google and the claimants had reached an out-of-courtsettlement. The full details are complicated - the text alone runs to 385 pages– and trying tosummarise it is no easy task. "Part of the problem is that it is basically incomprehensible," saysBlofeld, one of the settlement's most vocal British critics.Broadly, the deal provides a mechanism for Google to compensate authors and publishers whose rights it has breached (including giving them a share of any future revenue it generates fromtheir works). In exchange for this, the rights holders agree not to sue Google in future.This settlement hands Google the power - but only with the agreement of individual rights holders – to exploit its database of out-of-print books. It can include them in subscription deals sold to libraries or sell them individually under a consumer licence. It is these commercial provisions that are proving the settlement's most controversial aspect.Critics point out that, by giving Google the right to commercially exploit its database, thesettlement paves the way for a subtle shift in the company's role from provider of information to seller. "Google's business model has always been to provide information for free, and sell advertising on the basis of the traffic this generates," points out James Grimmelmann, associate professor at New York Law School. Now, he says, because of the settlement's provisions, Google could become a significant force in bookselling.Interest in this aspect of the settlement has focused on "orphan" works, where there is noknown copyright holder – these make up an estimated 5-10% of the books Google has scanned. Under the settlement, when no rights holders come forward and register their interest in a work, commercial control automatically reverts to Google. Google will be able to display up to 20% oforphan works for free, include them in its subscription deals to libraries and sell them to individual buyers under the consumer licence.It is by no means certain that the settlement will be enacted (执行) – it is the subject of afairness hearing in the US courts. But if it is enacted, Google will in effect be off the hook as far as copyright violations in the US are concerned. Many people are seriously concerned by this - and the company is likely to face challenges in other courts around the world.No one knows the precise use Google will make of the intellectual property it has gained byscanning the world's library books, and the truth, as Gleick, an American science writer and member of the Authors Guild, points out, is that the company probably doesn't even know itself. But what is certain is that, in some way or other, Google's entrance into digital bookselling will have a significant impact on the book world in the years to come.注意：此部分试题请在答题卡1上作答。

作文：Nothing succeeds without a strong willThere is a prevalent joke around young people saying that ‘quitting smoking is the easiest thing in the world, and I’ve done it for hundreds of times.’ This seemingly funny statement ironically reflects the fact that the determination of most youngsters is oftentimes started with enthusiasm, but the passion becomes increasingly weaker each day, and then diminishes as if there has been no such thing at all.It is obvious that their failure in ‘quitting smoking’ and decline of determination are all ascribed to their lack of will. Initially, every success involves several stages of setbacks and risks, and we need to summon up our will to conquer them. Moreover, there are enormous temptation in our path of pursuit of success. For instance, when we plan to quit smoking, our roommates may smoke freely in front of us; when we are eager to keep fit, our close friends may invite us to have late night snacks. Under these occasions, only strong will can assist us to resist the temptation, and persist in chasing our goals until we triumphantly realize them.In short, no dream will successfully come true if we do not have strong will. An old famous proverb says that ‘ where there is a will, there is a way’. Let us bear this motton in mind no matter how many thunders and thorns are on our roads ahead, then we will be successful with such precious and powerful spirit.[快速阅读]快速阅读1.
