For questions 1-7, choose the best answer from the four choices marked A), B), C) and D). For questions 8-10, complete the sentences with the information given in the passage.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 primarily a 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 builta 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's book-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。

2011年12月六级真题Part I WritingDirections:For this part, you are allowed 30 minutes to write a short essay entitled Excessive Use of Plastic Bags. You should write at least 120 words following the outline given below in Chinese.1.目前塑料袋存在的问题2.减少使用塑料袋的重要性3.如何做到减少使用塑料袋Excessive Use of Plastic BagsIn recent years, the excessive use of plastic bags has become a topic of great concern. Plastic bags are lightweight, convenient, and inexpensive to produce, which explains their popularity across the globe. However, their convenience comes at a significant cost to the environment.The problems associated with plastic bags are numerous. Firstly, plastic bags are non-biodegradable, which means they will persist in the environment for hundreds of years, causing serious pollution. They are often littered and end up in water bodies, where they pose a threat to marine life. Secondly, plastic bags are derived from fossil fuels, contributing to the depletion of non-renewable resources and exacerbating climate change.Reducing the use of plastic bags is of paramount importance. Firstly, it can help alleviate environmental pollution. By using reusable shopping bags made of cloth or fabric, we can significantly decrease the demand for plastic bags and reduce the amount of waste generated. This, in turn, can minimize the harmful effects on the ecosystem and protect marine life.Moreover, reducing the use of plastic bags can help conserve non-renewable resources. The production of plastic bags relies heavily on fossil fuels, which are finite and will eventually run out. By using alternative materials or adopting sustainable practices like utilizing biodegradable bags, we can ensure the sustainable use of resources for future generations.To achieve the goal of reducing plastic bag usage, several steps can be taken. Firstly, governments should introduce regulations or impose taxes on plastic bags to deter their use. This approach has proved effective in countries like Ireland, where a plastic bag tax has resulted in a significant reduction in usage. Secondly, promoting education and raising public awareness is crucial. By educating the public about theharms of plastic bags and the benefits of alternative options, individuals can make informed choices and actively participate in reducing plastic bag consumption.In conclusion, the excessive use of plastic bags has severe consequences for the environment and the sustainable use of resources. It is a collective responsibility to address this issue. By reducing plastic bag usage through regulatory measures, education, and public awareness campaigns, we can contribute to a greener and more sustainable future.Part III Listening ComprehensionSection ADirections:In this section, you will hear 8 short conversations and 2 long conversations.

Finally, when the passage is read for the third time, you should check what you have written.In the past,one of the biggest disadvantages of machines has been their inability to work on a micro-scale. For example,doctors did not have devices allowing them to go inside the human body to (36) health problems or to perform (37) surgery. Repair crews did not have a way of (38) broken pipes located deep within a high-rise (39) building. However, that's about to change. Advances in computers and biophysics have started a microminiature (超微) (40) that allows scientists to envision—and in some cases actually build— microscopic machines. These devices promise to (41) change the way we live and work. Micromachines already are making an impact. At Case Western Reserve University in Cleveland,Ohio, research scientists have designed a 4-inch silicon chip that holds 700 tiny (42) motors. At Lucas NovaSensor in Fremont,California,scientists have perfected theworld's first microscopic blood-pressure sensor. Threaded through a person's blood (43) , the sensor can provide blood pressure readings at the valve of the heart itself. (44) .Auto manufacturers, for example, are trying to use tiny devices (45) .

Read the passage carefully. Then answer the questions or complete the statements in the fewest possible words. Please write your answers on Answer Sheet 2.Questions 47 to 51 are based on the following passage.Leadership is the most significant word in today's competitive business environment because it directs the manager of a business to focus inward on their personal capabilities and style. Experts on leadership will quickly point out that "how things get done" influences the success of the outcomes and indicates a right way and a wrong way to do things. When a noted leader on the art of management, Peter Drucker,coined the phrase "Management is doing things right, leadership is doing the right things,"he was seeking to clarify the distinctions he associates with the terms.When Stephen Covey, founder and director of the Leadership Institute, explored leadership styles in the past decade, he focused on the habits of a great number of highly effective individuals. His Seven Habits of Highly Effective People became a popular bestseller very quickly. His ideas forced a reexamination of the early leadership paradigm (范例) ,which he observed centered on traits found in the character ethic and the personality ethic. The former ethic suggested success was founded on integrity, modesty, loyalty, courage, patience, and so forth. The personality ethic suggested it was one's attitude, not behavior, that inspired success, and this ethic was founded on a belief of positive mental attitude. In contrast to each of these ideas, Covey advocates that leaders need to understand universal principles of effectiveness, and he highlights how vital it is for leaders to first personally manage themselves if they are to enjoy any hope of outstanding success in their work environments. To achieve a desired vision for your business, it is vital that you have a personal vision of where you are headed and what you value. Business leadership means that managers need to "put first things first," which implies that before leading others, you need to be clear on your own values, abilities, and strengths and be seen as trustworthy.SSS_FILL47.To be good leaders, managers must pay close attention to theirown______.SSS_FILL48.According to Peter Drucker,leaders should be good at______.SSS_FILL49.The personality ethic suggests that people arc likely to succeed if they have______.SSS_FILL50.According to Stephen Covey,leaders who hope to achieve outstanding success need first of all to______.SSS_FILL51.Good leadership requires one to know one's own strengths and be able to win people's______.Section BDirections : There are 2 passages in this section. "Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A), B), C), and D). You should decide on the best choice and mark the corresponding letter on Answer Sheet 2 with a single line through the centre.Passage OneQuestions 52 to 56 are based on the following passage.What's the one word of advice a well-meaning professional would give to a recent college graduate? China? India? Brazil ? How about trade? When the Commerce Department reported last week that the tradedeficit in June approached $50 billion, it set off a new round of economic doom saying. Imports,which soared to $200.3 billion in the month,are subtracted in the calculation of gross domestic product. The larger the trade deficit, the smaller the GDP. Should such imbalances continue, pessimists say, they could contribute to slower growth.But there's another way of looking at the trade data. Over the past two years, the figures on imports and exports seem not to signal a double-dip recession—a renewed decline in the broad level of economic activity in the United States—but an economic expansion. The rising volume of trade—more goods and services shuttling in and out of the United States—is good news for many sectors. Companies engaged in shipping, trucking, rail freight, delivery, and logistics (物流)have all been reporting better than expected results. Therising numbers signify growing vitality in foreign markets—when we import more stuff, it puts more cash in the hands of people around the world, and U.S. exports are rising because more foreigners have the ability to buy the things we produce and market. The rising tide of trade is also good news for people who work in trade-sensitive businesses, especially those that **modities for which global demand sets the price—agricultural goods, mining, metals, oil.And while exports always seem to lag, U.S. companies are becoming more involved in the global economy with each passing month. General Motors sells as many cars in China as in America each month. While that may not do much for imports,it does help GM's balance sheet—and hence makes the jobs of U. S.-based executives more stable.One great challenge for the U.S. economy is slack domestic consumer demand. Americans are paying down debt, saving more,and spending more carefully. That's to be expected,given what we've been through. But there's a bigger challenge. Can U. S.-based businesses, large and small, figure out how to get a piece of growing global demand? Unless you want to pick up and move to India. or Brazil, or China, the best way to do that is through trade. It may seem obvious, but it's no longer enough simply to do business with our friends and neighbors here at home.Companies and individuals who don't have a strategy to export more,or to get more involved in foreign markets, or to play a role in global trade,are shutting themselves out of the lion's share of economic opportunity in our world.SSS_SINGLE_SEL52.How do pessimists interpret the U.S. trade deficit in June?A It could lead to slower growth of the national economy.B It reflects Americans' preference for imported goods.C It signifies a change in American economic structure.D It is the result of America's growing focus on domestic market.SSS_SINGLE_SEL53.What does the author say about the trade data of the past two years?A It indicates that economic activities in the U.S. have increased.B It reflects the fluctuations in the international market.C It shows that U.S. economy is slipping further into recession.D It signals decreasing domestic demand for goods and services.SSS_SINGLE_SEL54.Who particularly benefit from the rising volume of trade?A People who have expertise in international tradeB Producers of agricultural goods and raw materials.C Consumers who favor imported goods and services.D Retailers dealing in foreign goods and services.SSS_SINGLE_SEL55.What is one of the challenges facing the American economy?A Decreasing productivity.B People's reluctance to spend.C Competition from overseas.D Slack trade activities.SSS_SINGLE_SEL56.What is the author's advice to U.S. companies and individuals?A To import more cheap goods from developing countries.B To be alert to fluctuations in foreign markets.C To increase their market share overseas.D To move **panies to where labor is cheaper.Passage TwoQuestions 57 to 61 are based on the following passage.A recurring criticism of the UK's university sector is its perceived weakness in translating new knowledge into new products and services. Recently,the UK National Stem Cell Network warned the UK could lose its place among the world leaders in stem cell research unless adequate funding and legislation could be assured. We should takethis concern seriously as universities are key in the national innovation system.However, we do have to challenge the **plaint that the sector does not do enough in taking ideas to market. The most **parative data on the performance of universities and research institutions in Australia, Canada, USA and UK shows that, from a relatively weak starting position, the UK now leads on many indicators of commercialisation activity.When viewed at the national level, the policy interventions of the past decade have helped transform the performance of UK universities. Evidence suggests the UK's position is much stronger than in the recent past and is still showing improvement. But National data masks the very large variation in the performance of individual universities. The evidence shows that a large number of universities have fallen off the back of the pack, a few perform strongly and the rest chase the leaders.This type of uneven distribution is not peculiar to the UK and is mirrored across other economies. In the UK, research is concentrated: less than 25% of universities receive 75% of the research funding. These same universities are also the institutions producing the greatest share of PhD graduates, science citations, patents and licence income. The effect of policies generating long-term resource concentration has also created a distinctive set of universities which are research-led **mercially active. It seems clear that the。

本章精选20道数字推理，试题内容涵盖了历年《行政职业能力测验》真题类型，并辅之以精确的解析和基础知识补充，旨在培养广大考生快速、准确的数字推理答题能力。

例1、6，9，16，（），42，61A.21B.23C.27D.30解析：等差数列，原式后项减前项得到二级差数列：3、7、11、15、19，继续做差得到三级差数列：4、4、4、4为一个常数列；故答案为C。

等差数列常考形式为二级等差和三级等差，运算模式为相邻项作差得到后一项。

如：4、11、21、34、50为二级等差数列，原数列后项-前项得到二级数列：7、10、13、16是公差为3的等差数列。

-3、1、3、10、29、67为三级等差数列，原数列后项-前项得到二级数列：4、2、7、19、38，继续作差得到三级数列：-2、5、12、19是公差为7的等差数列。

等差数列的数项排列整体呈递增或递减趋势，直接作差（一级、二级、三级……）便可得出答案，在计算过程中一般可由前四项看出试题规律。

例2、2，6，15，28，（），78A.53B.55C.57D.59解析：等差数列变式，原数列可以化为：1×2、2×3、3×5、4×7、5×11、6×13，其中1、2、3、4、5、6是公差为1的等差数列，2、3、5、7、11、13是几个连续的质数列；故答案为B。

等差数列变式常见形式有两种：一是在等差的基础上每项分别加上或者乘以一个特定数列：自然数列、质数列、幂次数列等；如：2、4、7、12、21，原式可化为：1+2的0次方、2+2的1次方、3+2的2次方、4+2的3次方、5+2的4次方，其中加号前的数字组成公差为1的等差数列，加号后的数字组成公比为2的等比数列。

二是等差数列的级差数列组成特定数列：等比数列、连续质数列、幂次数列、和数列、周期数列等；如：-6、-2、5、9、16、20、27，其二级差数列为周期数列：4、7、4、7、4、7。

等差数列变式的数项排列整体呈递增或递减趋势，数据组合规律较复杂，要求考生具有一定的数据转化能力与敏感度，常见的数据转化形式有：1转化为X的0次方，2转化为1的N次方加1，8转化为2的立方或3的平方减1，25转化为5的平方或3的立方减2等。

例3、6，8，32/3，（），512/27A.128/6B.128/9C.142/6D.142/9解析：等比数列，原数列后项÷前项=4/3为一个常数列；故答案为B。

等比数列常考形式为基本型等比数列、二级等比数列、三级等比数列、多级等比数列。

如：6、6、12、48、384为二级等比数列，原数列后项÷前项得到二级数列：1、2、4、8是公比为2的等比数列。

1、1、1/3、1/9、1/9、1为三级等比数列，原数列后项÷前项得到二级数列：1、1/3、1/3、1、9，继续作商得到三级数列：1/3、1、3、9是公比为3的等比数列。

等比数列是各类公务员考试中出现频率较高的题型之一，公比为正整数时，数项排列规律一般呈递增或递减趋势，且变化幅度较大；公比为负数或分数时，数项排列无固定规律，具有较大的迷幻性，此时考生要仔细分析各项之间的数量关系。

例4、7，16，35，（），153A.50B.62C.74D.86解析：等比数列变式，每一项×2再加上一个自然数列得到下一项：7×2+2=16,16×2+3=35,35×2+4=74,74×2+5=153；故答案为C。

等比数列变式常考形式为两种：一是在等比数列的基础上每项分别加上一个特定数列，这个特定数列常见形式有：自然数列、常数列、质数列、幂次数列等；如：3、5、9、15、27，原数列可化为：1+2、2+3、4+5、8+7、16+11，其中加号前为公比为2的等比数列，加号后为质数列。

二是多级等比数列为特定数列：常数列、等差数列、连续质数列、幂次数列、和数列、周期数列等；如：1、2、6、24、100，原数列后项比前项得到二级数列：2、3、4、5为连续的自然数列。

等比数列变式一般综合性较强，直接观察数列并无明显规律，作商法（一级、二级、三级……）可以得到一个规律明显的新数列便于快速找出答案。

例5、4，6，10，16，（），42A.26B.24C.30D.22解析：和差数列，原数列前一项+后一项=第三项，即4+6=10,6+10=16,10+16=26,16+26=42；故答案为A。

和差数列常考形式为两项和差与三项和差，运算一般较简单，数项之间有明显的加和关系。

例6、1，3，6，10，（），21A.11B.18C.14D.15解析：和差数列变式，1+3=22，3+6=32，6+10=42，10+15=52，15+21=62；故答案为D。

和差数列变式常考形式有四种形式：一是相邻两项之和或差组成特定数列：等差数列、等比数列、幂次数列、质数列、周期数列等；如：0、1、1、3、5为和差数列变式，原数列前项+后项得到二级数列：1、2、4、8是公比为2的等比数列。

二是(第一项+第二项)+常数=第三项，（第一项+第二项）+基本数列=第三项；如2、3、7、12、21为和差数列变式，原数列前项+后项+常数（2）得到第三项。

三是第一项×常数+第二项=第三项，第一项+第二项×常数=第三项，第一项×常数+第二项×常数=第三项；如：1、3、5、11、21为和差数列变式，原数列前项×2+后项=第三项。

四是第一项×基本数列+第二项×基本数列=第三项；如：1、2、3、16、265为和差数列变式，原数列可化为：1×1+2×1=3，2×2+3×4=16，3×3+16×16=265，其中第一个乘号后的数字组成连续的自然数列，第二个乘号后的数字组成公比为4的等比数列。

和差数列变式的数项组合规律一般较复杂，直接观察并无明显规律，和差法（两项和差、三项和差……）可以得到一个规律明显的新数列便于快速找出答案。

例7、1，2，2，4，8，（）A.16B.24C.32D.48解析：积商数列，第一项×第二项=第三项，即1×2=2,2×2=4,2×4=8,4×8=32；故答案为C。

积商数列常考形式为二项积商数列和三项积商数列；积商数列中当数项为正整数时，数列整体数字变化幅度较大，当数项有分数与整数混合时，增减幅度有所缓和。

例8、2，2，6，14，（）A.26B.46C.66D.86解析：积商数列变式，前一项×后一项+2=第三项，即2×2+2=6,2×6+2=14,6×14+2=86；故答案为D。

积商数列变式的常考形式有两种：一是相邻两项之积商组成特定数列：等差数列、等比数列、幂次数列、质数列、周期数列等。

二是第一项×第二项+常数=第三项，第一项×第二项+基本数列=第三项。

积商数列变式整体数项的变化幅度较大，数据组合规律较复杂，要求考生具有一定的数据转化能力与敏感度。

例9、1，4，27，256，（）A.3125B.625C.1024D.729解析：多次幂数列，原数列可以化为：1的1次方，2的2次方，3的3次方，4的4次方，5的5次方，其中1、2、3、4、5为连续的自然数；故答案为A。

多次幂数列常考形式为平方数列、立方数列、多次方数列；整体数项变化幅度较大，各项数据具有明显的幂次特征。

例10、2，6，13，24，（）A.27B.31C.37D.41解析：多次幂数列变式，原数列可以化为：12+1=2,22+2=6,32+4=13,42+8=24,52+16=41，其中1、2、3、4、5为连续的自然数，1、2、4、8、16为公比为2的等比数列；故答案为D。

多次幂数列变式常考形式为在典型多次幂的基础上各项分别加或乘一个特定数列：常数列、自然数列、等差数列、等比数列等；数据字和规律较为复杂，整体数项变化幅度较大，要求考生具有一定的数据转化能力与敏感度，常见的数据转化形式有：0转化为0的n次方，1转化为任意自然数的0次方等。

例11、1/2，1/3，5/6，7/6，( )A.3/2B.5/3C.2D.13/6解析: 分式、小数数列，前一项+后一项=第三项，1/2+1/3=5/6，1/3+5/6=7/6，5/6+7/6=2；故答案为C。

分式、小数数列是各类公务员考试中出现频率较高的题型之一，一般难度较大，遇到此类题型优先考虑和差法、积商法等方式快速处理题干数项，找出各项之间的数量关系。

例12、1，2，13/5，（），41/13A.3B.13/6C.21/8D.27/4解析：分式、小数数列变式，原数列可化为：（12+1）/2，（22+2）/3，（32+4）/5，（42+8）/8，（52+16）/13，其中分母为连续的质数列，分子加号以前为连续自然数的平方，加号以后为以2为公倍数的等比数列；故答案为A。

分式、小数数列变式数据组合规律较复杂，组合特征一般可分为两种情况：一是分子、分母分别组成特定数列；二是分子、分母通过基本数量运算得到下一项的分子或分母，遇到此类题型可用猜证结合的方法解出答案。

例13、1，2，3，（），4，5，（），7A.4，6B.4,7C.3,6D.3,7解析：组合数列，奇数项组成和数列，偶数项组成连续的质数列；故答案为D。
