大家好，我是老梁考研数学！这两天学校期末事情多，使得《真题一题多解系列》断更时间较长，抱歉！今天老梁继续给大家推送《考研数学真题分类解析系列》第008期，选择一道幂指函数极限计算的客观题，对于客观题，除了通用解法之外，特殊值法也上常常采用的方法，除了对函数采用特殊值，也可对参数采用特殊值。真题及解析【例008】（2010数1）【分析一】这是一个1的无穷幂指型未定式极限的计算，常用下列简便公式：【解法一】【分析二】将极限式中分式项倒数变形、再利用乘积的四则运算，简化计算。【解法二】【分析三】由于是客观题，且极限式含有参数，因此可对两个参数取特殊值排除错误选项。【解法三】【评注】特殊值法，选取特殊值的原则是能区别选项，如本题也可选b=-a=1。总结（1）解法一是解决幂指函数未定式极限的通用方法，在本题的三个解法中是最费时的方法；（2）如果一个极限式所含分式“头重脚轻”，即分子为单项式而分母为几个单项的和，这时一般可采取倒数的方法简化计算；（3）若客观题含有抽象函数或参数，则可使用特殊指法，对函数或参数取不同的值来排除错误选项（选择题）或直接得到结果。方法总结 归纳题型奇思妙解 就找老梁往期回顾考研数学｜两类含有限加和幂指型未定式极限计算｜无穷大(小)替换考研数学｜真题一题多解系列，精选007｜已知极限反求未知参数考研数学｜真题一题多解系列，精选006｜中值问题考研数学｜真题一题多解系列，精选005｜5种方法30年考研数学真题分类解析｜专题三：极限基本理论

历年的研究生考试当中，考研数学都是很多考生的拦路虎。而在考研数学中，概率统计部分又是部分同学的老大难。为了帮助考研同学更好的迎接新一年的研究生考试，小编整理过去十年的数学考研真题。经过小编认真研究，现将历年真题中存在一些规律，进行归纳总结，希望能够对正在考研复习的2020年考生有所帮助。一、2010年~2019年考研数学一概率统计中出现的主要知识点根据2018年最新的考研数学大纲，数学一考查的内容一共包含八章内容，这八章内容在一般的概率统计教材应该都是可以找到的。如图：考研数学的大纲近十年来基本上没有发生什么大的变化，小编估计2020年也不会发生很大的变化。所以，在目前阶段我们完全可参照2019年的考研大纲有针对性的进行复习。通过对近十年的考研真题的分析，研究生考试中的题目实际上是有一定的侧重点和规律性的。由于篇幅所限，在此小编简要介绍常考知识点和侧重点，详细介绍另文介绍。第一章，随机事件和概率是整个考研数学概率统计的基础，本章的知识点都是一些基本的定义和运算。一般情况，这一章的知识点不会单独拿出来考一个大题，考查形式都是融合到了后面各章知识点来考查。第二章随机变量及分布是作为第三章多维随机变量及分布的基础。因此在这两章中，考试题目主要出现在多维随机变量这一部分。多维随机变量这一章是研究生考试出题的重点章节，可以说每年必考，每年只是考试形式的改变而已。第四章随机变量的数字特征，这部分内容也是作为基础，重点在掌握基本的概念和性质。本章的知识点，不会单独考查，主要有两种考察形式：1.作为大题中计算完成之后，顺带着求个期望或者方差；2.作为计算题计算过程中需要用到的知识点。第五章.大数定律和中心极限定理，这一章的知识点不太容易出现在大题中，所以在以往的真题中，近十年只有一年的题目中用的了大数定律，其余各年本章知识点没有考查过。第六、七、八章是统计部分，这三部分重点在第七章参数估计。而参数估计这一章中，重点又在点估计的两种方法：矩估计法和最大似然估计法。近十年的研究生考试中，矩估计考了三次，最大似然估计法考了九次，几乎年年必考。最大似然估计法是概率统计所有知识点中考查次数最多的一个。而区间估计和假设检验则考查相对较少，近十年中各考查了一次，而且还是填空和选择的形式。二、近年考研数学一概率统计主要知识点的考查趋势小编将近十年的考研真题做了统计，考研数学的考试题目仍然是以考查基础为主。随便拿出哪一个题目来看都没有超纲或者特别难、怪的题目。比如多维随机变量和参数估计这两部分是每年的考试重点，几乎每年必考。小编以这两章的题目为例给大家解析，为什么考查的就是基础知识，很多同学却不会做呢？多维随机变量中考查的题目，在考研大纲中要求的就是二维随机变量，实际考查的也是二维随机变量。在前些年考试考查的都是单纯的离散型随机变量或者连续型随机变量，也就是题目当中的二维随机变量的两个随机变量类型相同。类型相同的二维随机变量是平时连续较多，相对简单的题目。而近年来，考查的二维随机变量更多的是一个是离散的，另外一个是连续的。这类二维随机变量在日常学习中较少遇到，这给考试学生增加一定的难度。参数估计这一章的知识点考查的内容和形式相对固定，也是考查重点之一。前面小编介绍过，参数估计这一部分的最大似然估计几乎是每年必考，并且形式固定。近十年考题中，这个知识点考查了九次，全部都在整张数学试卷的最后一题（23）。并且，在这九次考查中，问题几乎完全一样：求相关参数的最大似然估计。方法也基本一致：除去2015年另外的八年完全可以按照常规方法求出来。所用的方法大家都非常熟悉：1.写出似然函数；2. 对数似然函数；3. 求最大值（求导数等于零）；4.解出相关参数。另外，区间估计和假设检验在前些年没有考过，只是在2016年填空形式考查了区间估计。2018年考查了假设检验的相关内容。但是，即使这两年的考查中，只要理解的相关内容就可以很多写出结果，根本不需要那些繁琐的公式。三、在考研数学一考试中概率统计哪些知识点会成为测2020年考研考试的热点？根据以上整理的主要知识点和近十年主要考点，小编也斗胆预测一下2020年研究生考试那些知识点会成为考试的重点。首先，考查基础知识这样的主基调一定不会改变。就像第一、而章这样的基本知识章节，可能不会单独的出题目来考查，但是这些知识一定不会缺席。这些知识完全可以融合到其它知识点中去考查。换句话说，离开这些基本概念其它知识点的题目也不可能顺利完成。比如，多维随机变量的相关题目必然会用到一维随机变量掌握知识；数理统计的相关题目一定会用到随机变量的数字特征。所以，基础知识一定是考研学生复习的首要任务。具体的知识点，最大似然估计法过去十年考查了九年，根据统计知识，2020年考查的概率还是非常大的。另外，在考研数学概率论中计算完统计量之后，考查一下无偏性和有效性也是顺便的事情。区间估计和假设检验在早期从没有考查过，但是在近几年出现了两次，这是不是一种要加强考查这部分知识点的信号呢？当然，这只是小编个人见解和猜测，类似的规律大家都可以去从往年考研真题当中去寻找。四、如何复习应对考研数学一中概率统计相关题目呢？每个人的情况不尽相同，首先根据个人实际情况，趁着时间还来得及，制定详细的复习计划。在研究生考试中考查题目几乎都是考查我们日常学习中的基础知识点。只是，有些知识点在考试中考查方式与我们平时学习的不太一样，导致不太习惯而已。所以，在复习中首先要重视相关的基础知识的理解，在充分理解的基础上，将考研题目和日常学习中的不同点找出来重点练习。比如，小编前面谈到过的混合型二维随机变量。另外，数量统计部分，大部分同学普遍感到公式多、大，不好记。实际上，数理统计大家也应该把重点放到基本概念的理解上，真正的理解了基本的概念和原理，公式自然就能够记住，甚至根本都不用去记忆哪些公式。比如，小编前面提到的区间估计和假设检验过去十年考查过两次，实际只要真正理解了相关的概念，根本不用公式直接就可以看出结果。因此，对于研究生考试中概率统计部分的复习，要具体情况具体分析。对于前四章的知识点（概率部分），主要以记忆相关公式，多练习为主；而对于后三章（数理统计部分），把重点放到理解上。

(40 points)Text 1A group of labour MPs, among them Yvette Cooper, are bringing in the new year with a call to institute a UK "town of culture" award. The proposal is that it should sit alongside the existing city of culture title, which was held by Hull in 2017 and has been awarded to Coventry for Zozl. Cooper and her colleagues argue that the success of the crown for Hull, where it brought in220m of investment and an avalache of arts, out not to be confined to cities.Britain' town, it is true are not prevented from applying, but they generally lack the resources to put together a bit to beat their bigger competitions. A town of culture award could, it is argued, become an annual event, attracting funding and creating jobs.Some might see the proposal as a boo by prize for the fact that Britain is no longer be able to apply for the much more prestigious title of European capital of culture, a sought-after award bagged by Glasgow in 1990 and Livorpool in 2008. "A cynic might speculate that the UK is on the verge of disappearing into an endless fever of self-celebration in its desperation to reinvent itself for the post-Brexit world: after town of culture, who knows that will follow-village of culture? Suburb of culture? Hamlet of culture?It is also wise to recall that such titles are not a cure-all. A badly run "year of culture"washes in and out of a place like the tide, bringing prominence for a spell but leaving no lasting benefits to the community. The really successful holders of such titles are those that do a great deal more than fill hotel bedrooms and bring in high-profile arts events and good press for a year. They transform the aspirations of the people who live there; they nudge the self-image of the city into a bolder and more optimistic light.It is hard to get right, and requires a remarkable degree of vision, as well as cooperation between city authorities, the private sector, community groups and cultural organisations. But it can be done: Glasgow's year as European capital of culture can certainly be seen as one of complex series of factors that have turned the city into the power of art, music and theatre that it remains today.A "town of culture" could be not just about the arts but about honouring a town's peculiarities-helping sustain its high street, supporting local facilities and above all celebrating its people and turn it into action.21. Cooper and her colleagues argue that a "town of culture" award could [A] consolidate the town-city ties in Britain.[B] promote cooperation among Britain's towns.[C] increase the economic strength of Britain's towns.[D] focus Britain's limited resources on cultural events.22. According to Paragraph 2, the proposal might be regarded by some as [A] a sensible compromise.[B] a self-deceiving attempt.[C] an eye-cotching bonus.[D] an inaccessible target.23. The author suggests that a title holder is successful only if it [A] endeavours to maintain its image.[B] meets the aspirations of its people.[C] brings its local arts to prominence.[D] commits to its long-term growth.24. Glasgow is mentioned in Paragraph 3 to present [A] a contrasting case.[B] a supporting example.[C]a background story.[D] a related topic.25. What is the author's attitude towards the proposal?[A] Skeptical[B] Objective[C] Favourable[D] Critical答案（21-25）21.D focus Britain's limited resources on cultural events.22.B a self-deceiving attempt.23.D commits to its long-term growth.24.B a supporting example.25.C Favourable.Text2Scientific publishing has long been a licence to print money, Scientists need journals in which to publish their research, so they will supply the articles without monetary reward. Other scientists perform the specialised work of peer review also for free, because it is a central element in the acquisition of status and the proction of scientific knowledge.With the content of papers secured for free, the publisher needs only find a market for its journal. Until this century, university libraries were not very price sensitive. Scientific publishers routinely report profit margins approaching 40% on their operations, at a time when the rest of the publishing instry is in an existential crisis.The Dutch giant Elsevier, which claims to publish 25% of the scientific papers proced in the world, made profits of more than f 900m last year, while UK universities alone spent more than f 210m in 2016 to enable researchers to access their own publicly funded research;both figures seem to rise unstoppably despite increasingly desperate efforts to change them.The most drastic, and thoroughly illegal, reaction has been the emergence of Sci-Hub, a kind of global photocopier for scientific papers, set up in 2012, which now claims to offer access to every pay walled article published since 2015. The success of Sci-Hub, which relies on researchers passing on copies they have themselves legally accessed, shows the legal ecosystem has lost legitimacy among its users and must be transformed so that it works for all participants.In Britain the move towards open access publishing has been driven by funding bodies.In some ways it has been very successful. More than half of all British scientific research is now published under open access terms; either freely available from the moment of publication,or pay walled for a year or more so that the publishers can make a profit before being placed on general release.Yet the new system has not worked out any cheaper for the universities. Publishers have responded to the demand that they make their proct free to readers by charging their writers fees to cover the costs of preparing an article. These range from around500 to $5,000.A report last year pointed out that the costs both of subscriptions and of these "article preparation costs" had been steadily rising at a rate above inflation.In some ways the scientific publishing model resembles the economy of the social internet:labour is provided free in exchange for the hope of status, while huge profits are made by a few big firms who run the market places. In both cases, we need a rebalancing of power.26. Scientific publishing is seen as "a licence to print money" partly because [A] its funding has enjoyed a steady increase.[B] its marketing strategy has been successful.[C] its payment for peer review is reced.[D] its content acquisition costs nothing.!27. According to Paragraphs 2 and 3, scientific publishers Elsevier have [A] thrived mainly on university libraries.[B] gone through an existential crisis.[C] revived the publishing instry.[D] financed researchers generously.28. How does the author feel about the success of Sci-Hub? [A] Relieved.[B] Puzzled.[C] Concerned.[D] Encouraged.29. It can be learned from Paragraphs 5 and 6 that open access terms [A] allow publishers some room to make money.[B] render publishing much easier for scientists.[C] rece the cost of publication substantially.[D] free universities from financial burdens.30. Which of the following characterises the scientific publishing model?[A] Trial subscription is offered.[B] Labour triumphs over status.[C]Costs are well controlled.[D] The few feed on the many.答案（26-30）26.D its content acquisition costs nothing.27.A thrived mainly on university libraries.28.D Encouraged.29.A allow publishers some room to make money.30.D The few feed on the many.Text 3Progressives often support diversity mandates as a path to equality and a way to level the playing field. But all too often such policies are an insincere form of virtue-signaling that benefits only the most privileged and does little to help average people.A pair of bills sponsored by Massachusetts state Senator Jason Lewis and House Speaker Pro Tempore Patricia Haddad, to ensure "gender parity" on boards and commissions, provide a case in point.Haddad and Lewis are concerned that more than half the state-government board are lessthan40 percent female. In order to ensure that elite women have more such opportunities, they have proposed imposing government quotas. If the bills become law, state boards and commissions will be required to set aside 50 percent of board seats for women by 2022.The bills are similar to a measure recently adopted in Califomia, which last year became the first state to require gender quotas for private companies. In signing the measure, California Governor Jerry Brown admitted that the law, which expressly classifies people on the basis of sex, is probably unconstitutional.The US Supreme Court frowns on sex based classifications unless they are designed to address an "important" policy interest, Because the California law applies to all boards, even where there is no history of prior discrimination, courts are likely to rule that the law violates the constitutional guarantee of "equal protection".But are such government mandates even necessary? Female participation on corporate boards may not currently mirror the percentage of women in the general population, but so what?The number of women on corporate boards has been steadily increasing without government interference. According to a study by Catalyst, between 2010 and 2015 the share of women on the boards of global corporations increased by 54 percent.Requiring companies to make gender the primary qualification for board membership will inevitably lead to less experienced private sector boards. That is exactly what happened when Norway adopted a nationwide corporate gender quota.Writing in The New Republic, Alice Lee notes that increasing the number of opportunities for board membership without increasing the pool of qualified women to serve on such boards has led to a "golden skirt "phenomenon, where the same elite women scoop up multiple seats on a variety of boards.Next time somebody pushes corporate quotas as a way to promote gender equity,remember that such policies are largely self-serving measures that make their sponsors feelgood but do little to help average women.31.The author believes that the bills sponsored by Lewis and Haddad will [A] help little to rece gender bias.[B] pose a threat to the state government.[C] raise women's position in politics.[D] greatly broaden career options.32. Which of the following is true of the Califormia measure?[A] It has irritated private business owners.[B] It is welcomed by the Supreme Court.[C] It may go against the Constitution.[D] It will settle the prior controversies.33. The author mentions the study by Catalyst to illustrate [A] the harm from arbitrary board decision. [B]the importance of constitutional guarantees.[C] the pressure on women in global corporations.[D] the needlessness of government interventions.34. Norway's adoption of a nationwide corporate gender quota has led to [A] the underestimation of elite women's role[B] the objection to female participation on boards.[C]the entry of unqualified candidates into the board.[D] the growing tension between labor and management.35. Which of the following can be inferred from the text?[A] Women's need in employment should be considered.[B] Feasibility, should be a prime concern in policy making.[C] Everyone should try hard to promote social justice.[D] Major social issues should be the focus of legislation.答案（31-35）31.A help little to rece gender bias.32.C It may go against the Constitution.33.D the needlessness of government interventions.34.C the entry of unqualified candidates into the board.35.B Feasibility should be a prime concern in policymaking.Text4 :Last Thursday, the French Senate passed a digital services tax, which would impose an entirely new tax on large multinationals that provide digital services to consumers or users in France. Digital services include everything from providing a platform for selling goods and services online to targeting advertising based on user data, and the tax applies to gross revenue from such services. Many French politicians and media outlets have referred to this as a"GAFA tax," meaning that it is designed to apply primarily to companies such as Google,Apple, Facebook and Amazon-in other words, multinational tech companies based in the United States.The digital services tax now awaits the signature of President Emmanuel Macron, who has expressed support for the measure, and it could go into effect within the next few weeks.But it has already sparked significant controversy, with the Unite Sates trade representative opening an investigation into whether the tax discriminates against American companies,which in turn could lead to trade sanctions against France.The French tax is not just a unilateral move by one country in need of revenue. Instead,the digital services tax is part of a much larger trend, with countries over the past few years proposing or putting in place an alphabet soup of new international tax provisions. These have included Britain's DPT (diverted profits tax).Australia's MAAL (multinational antiavoidance, law), and India's SEP (significant economic presence) test, to name but a few. At the same time, the European Union. Spain,Britain and several other countries have all seriously contemplated digital services taxes.These unilateral developments differ in their specifics, but they are all designed to tax multinationals on income and revenue that countries believe they should have a right to tax,even if international tax rules do not grant them that right. In other words, they all share a view that the international tax system has failed to keep up with the current economy.In response to these many unilateral measures, the Organization for Economic Cooperation and Development (OECD) is currently working with 131 countries to reach aconsensus by the end of 2020 on an international solution. Both France and the United States are involved in the organization's work, but France's digital services tax and the American response raise questions about what the future holds for the international tax system.France's planned tax is a clear warning: Unless a broad consensus can be reached on reforming the international tax system, other nations are likely to follow suit, and American companies will face a cascade of different taxes from dozens of nations that will prove burdensome and costly.36.The French Senate has passed a bill to [A] regulate digital services platforms.[B] protect French companies interests.[C] impose a levy on tech multinationals.[D] curb the influence of advertising.37. It can be learned from Paragraph 2 that the digital services tax [A] may trigger countermeasures against France.[B] is apt to arouse criticism at home and abroad.[C] aims to ease international trade tensions.[D] will prompt the tech giants to quit France.38. The countries adopting the unilateral measures share the opinion that [A] redistribution of tech giants' revenue must be ensured.[B] the current international tax system needs upgrading.[C] tech multinationals' monopoly should be prevented.[D] all countries ought to enjoy equal taxing rights.39. It can be learned from Para 5 that the OECO's current work [A] is being resisted by US companies.[B] needs to be readjusted immediately.[C] is faced with uncertain prospects.[D] needs to in involve more countries.40. Which of the following might be the best title for this text?[A] France Is Confronted with Trade Sanctions[B] France leads the charge on Digital Tax[C] France Says "NO" to Tech Multinationals[D] France Demands a Role in the Digital Economy答案（36-40）36.C impose alevy on tech multinationals.37.A may trigger countermeasures against France.38.B the current international tax system needs upgrading39.C is faced with uncertain prospects.40.B France leads the charge on Digital TaxPart B Directions:In the following text, some sentences have been removed.

This mutual gaze is a major part of the attachment between mother and child. In althood, looking someone else in a pleasant way can be a complimentary sign of paying attention. It can catch someone's attention in a crowded room, "Eye contact and smile" can signal availability and confidence, a common-sense notion supported in studies by psychologist Monica Moore.42. Neuroscientist Bonnie Augeung found that the hormone oxytocin increased the amount of eye contact from men toward the interviewer ring a brief interview when the direction of their gaze was recorded. This was also found in high- functioning men with some autistic spectrum symptoms, who may tend to avoid eye contact. Specific brain regions that respond ring direct gaze are being explored by other researches, using advanced methods of brain scanning.43. With the use of eye-tracking technology, Julia Minson of the Harvard Kennedy School of Government concluded that eye contact can signal very different kinds of messages,depending on the situation. While eye contact may be a sign of connection or trust in friendly situations, it's more likely to be associated with dominance or intimidation in adversarial situations. "Whether you' re a politician or a parent, it might be helpful to keep in mind that trying to maintain eye contact may backfire if you' re trying to convince someone who has a different set of beliefs than you," said Minson.44. When we look at a face or a picture, our eyes pause on one spot at a time, often on the eyes or mouth.
