16年考研数二真题答案

The supermarket is designed to lure customers into spending as much time as possible within its doors.超市的设计目的是吸引顾客在超市内尽可能长时间的停留。The reason for this is simple:原因很简单The longer you stay in the store, the more stuff you'll see, and the more stuff you see, the more you'll buy.你在店里待的时间越长，你看到的东西就越多，你看到的东西越多，你买的东西就越多。And supermarkets contain a lot of stuff.超市里有很多东西。The average supermarket, according to the Food Marketing Institute, carries some 44,000 different items, and many carry tens of thousands more.根据食品营销协会的数据，平均每家超市有大约44，000种不同的商品，而且有很多超市有比这多数万件。The sheer volume of available choice is enough to send shoppers into a state of information overload.可供选择的数量之多足以使购物者陷入信息过载的状态。According to brain-scan experiments, the demands of so much decision-making quickly become too much for us.根据脑部扫描实验，如此多的决策要求使我们很快承受不了。After about 40 minutes of shopping, most people stop struggling to be rationally selective,在大约40分钟的购物之后，大多数人不再挣扎于理性的选择，and instead began shopping emotionally-which is the point at which we accumulate the 50 percent of stuff in our cart that we never intended buying.而是开始冲动性购物，在这时候，我们把50%从来不打算买的东西放进购物车里。

(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. These pauses typically occur at about three per second, and the eyes then jump to another spot, until several important points in the image. are registered like a series of snapshots. How the whole image is then assembled and perceived is still a mystery although it is the subject of current research.45. In people who score high in a test of neuroticism, a personality dimension associated with self-consciousness and anxiety, eye contact triggered more activity associated with avoidance,according to the Finnish researcher Jari Hietanen and colleagues "Our findings indicate that people do not only feel different when they are the centre of attention but that their brain reactions also differ." A more direct finding is that people who scored high for negative emotions like anxiety looked at others for shorter periods of time and reported more comfortable feelings when others did not look directly at them.答案（41-45）41.

(10points)Following the explosion of creativity in Florence ring the 14h century known as the Renaissance, the modern world saw a departure from what it had once known. It turned from God and the authority of the Roman Catholic Church and instead favoured a more humanistic approach to being. Renaissance ideas had spread throughout Europe well into the 17h century,with the arts and sciences flourishing extraordinarily among those with a more logical disposition. (46) with the Church's teachings and ways of thinking eclipsed by the Renaissance,the gap between the Medieval and modern periods had been bridged leading to new and unexplored itellectual territories.During the Renaissance, the great minds of Nicolaus Copernicus, Johannes Kepler and Galileo Galilei demonstrated the power of scientific study and discovery. (47) Before each of their revelations many thinkers at the time had sustained more ancient ways of thinking.including the geo-centric view that the Earth was a the centre of our universe. Copernicus theorized in 1543 that all of the planets that we knew of revolved not around the Earth, but the Sun, a system that was later upheld by Galileo at his own expense. Offering up such a theory ring a time of high tension between scientific and religious minds was branded as heresy and any such heretics that continued to spread these lies were to be punished by imprisonment or even death.(48) Despite attempts by the Church to suppress. this new generation of logicians and rationalists, more explanations for how the universe functioned were being made at a rate that the people could no longer ignore.It was with these great revelations that a new kind of philosophy founded in reason was born.The Church's long- standing dogma was losing the great battle for truth to rationalists and scientists. This very fact embodied the new ways of thinking that swept through Europe ring most of 17h century. (49) As many took on the ty of trying to integrate reasoning and scientific philosophies into the world, the Renaissance was over and it was time for a new era-the Age of Reason.The 17h and I8h centuries were times of radical change and curiosity, Scientific method,rectionism and the questioning of Church ideals was to be encouraged, as were ideas of liberty, tolerance and progress. (50) Such actions to seek knowledge and to understand what information we already knew were captured by the Latin phrase' sapere aude' or dare to know',after Immanuel Kant used it in his essay" An Answer to the Question: What is Enlightenment?".It was the purpose and responsibility of great minds to go forth and seek out the truth, which they believed to be founded in knowledge.答案（46-50）46.随着教会的教义和思维方式在文艺复兴时期黯然失色，中世纪与现代之间的鸿沟得以弥合，从而出现了新的及尚未开发的知识领域。47.在每个真理揭示之前，当时的许多思想家都采用了更古老的思维方式，仍旧沿用以前的思维模式，其中包括认为地球是宇宙中心的地球中心说。48.尽管教会试图镇压这-代逻辑学家和理性主义者，但人们对宇宙如何运转的解释却越来越多，并且以-种不容忽视的速度在增加。49.当许多人承担起将理性科学的哲学融入世界的责任时，文艺复兴时代已经结束，并且开启了一个新的时代。50.此类寻求知识和了解已知信息的行为被拉丁语概括为：“sapere aude"即"敢于求知”作文Section ll WritingPart A51.

(20 points)大作文：习惯良好的时间管理习惯 【参考范文】Portrayed distinctively by the two cartoons above is an impressive scene: a girl in the left picture is doing homework and saying that early completion is better. Nevertheless, the boy in the right picture is sitting in front of the desk and saying that he will not finish the homework until the last minute.Undoubtedly, the symbolic implication of the pictures is to show us that importance should be attached to the formation of good habits, especially the good habit of time management. On the one hand, efficient time management is critical to personal development. As the old saying goes,“Time is money," and in the fast-paced modern life, it seems that we always have a lot of things to do and we are very busy. In the face of such a situation, we have to realize that efficiency holdsthe key to saving time and time management skills hold the key to personal success. On the other hand, good time management habits play a vital role in the development of the whole society. There is no doubt that, to a large extent, social progress is closely related to the efforts of each indivial. If we can develop the good habit of time management, we are much more likely to improve efficiency and have a better performance in the learning and working process, which is anintegral part of social advances and prosperity.From what has been mentioned above, we can come to the conclusion that the sense of efficient time management skills is of equal importance in personal and social progress.Therefore,we ought to take advantage of the phenomenon to enlighten the public and the press is expected to take a lead in advertising the value of developing good time management habits. Only in this way can we have a bright future.以上便是整理的2020年全国硕士研究生入学统一考试英语一试题及答案，2021考研的小伙伴可以参考真题，准备明年12月的考研初试。下面分享一份公共课书单，希望对大家有用：【英语书单】单词：闪过英语《考研词汇闪过》按重要程度划分了频考词、基础词、偶考词、超纲词，划重点，后期冲刺只背高频词和基础词，省时间。真题：《考研真相》（英语二：考研圣经）：一词一句讲解真题，重点词汇和每个句子都有详细讲解，不怕你看不懂，还有排除干扰项的方法，帮助提高答对率，适合基础弱的人。作文：英语一《写作160篇》/英语二《写作宝中宝》：通过词句段篇先教你学会写作文，再用三步作文法帮你拔高，专门针对基础薄弱的。【数学书单】《张宇真题大全解》：从94年到现在的真题都包括了，讲解很好，帮助研究数学题型。李永乐王式安660题：用这本书练习做题，都是经典题型！同济六版/七版《高等数学》上、下同济五版/六版《线性代数》课本：《线性代数》、《概率论》、《数理统计》【政治书单】官方红宝书（政治大纲解析）；风中劲草（三本书）、肖秀荣系列：精讲精练、1000题、讲真题、形势与政策、冲刺八套卷、最后四套卷；蒋中挺冲刺5套卷；启航20天20题

2020年考研已经过去一大半，走出数学考场的同学们，心情可能不是特别好，作为2016年考过数学一的学长，非常理解大家的心情。因为，回顾过去十年考研，数学最难的可能就是2010年与2016年，这两年的考研数学，无论是数学一、数学二还是数学三，无一例外都很难，不光难在出题套路有所变化，而且计算量也超级大。就拿2016年来说，学长考的是数学一，从做选择题开始，到填空题，就已经发现苗头不大对劲，因为，做过三遍真题的我，发现，这玩意跟做过的真题差太远了，当我做到大题的时候，心情已经非常沉重了。在考数学的考场上，就有女生一直在哭，原来不止我一个人觉得难，而是大家都觉得难，然后，心态稍微调整了下，继续将后面的大题都“写满了”，仅仅是写满了，而不是做出来了，因为，没有一道题的答案是完整能算出来的。当然，最后分数线出来以后，证明确实很难，因为分数线真的很低，所以，很幸运，学长也过线了。那么，2020年的考研数学到底难不难呢？是不是与2016年一样难？我们看看已经考完的同学都是怎么说的呢？我们在网上分别找一些考数学一、数学二、数学三的小伙伴们。数学一下面这位同学说：“考的数学一，在他看来，数学一基本上没有时间思考，本以为这题空过去，先做后面简单的，结果发现，越高山丘才发现，都是珠穆朗玛峰”。这位同学，觉得后面的每一道题都难于前面的题，可见今年的数学一真的不简单，没有时间思考，多半是因为计算量大，并且他还提到有同学因为草稿纸与监考老师起了争执，看来计算量确实不小。数学二下面这位同学，考数学二，他虽然说得有点夸张，但是，也说明了今年的数学二也不简单。看看下面这位同样考数学二的同学，这位同学的感受与上面一样，感觉数学二是30年来最难的一次，总体来说，选择题与填空题感觉比较简单，大题比较难，大概有5个大题卡住了，包括两个线代大题。还有一个双重积分和证明和求渐近线。还是考数学二的同学，感受：“原地爆炸，有史以来最难”，心疼考数学二的宝宝们！依旧是数学二的同学，依旧是难在计算量大上。数学三考数学三的一位同学，说，难度偏大，主要在于计算量大。看看下面这两位同样考数学三的同学，感受依旧是一个字：“难”。好了，关于考研亲历者的感受，我们就看到这里，下面进行一个总结。2020年考研数学，整体来说，无论是数学一、数学二、还是数学三，都偏难，尤其是数学二，根据同学们的感受来分析，可能是最近几年最难的一次。我们看一份来自蒋中挺老师创建的关于2020考研数学难易程度的投票，这个投票有11.7万人进行了投票，其中有6.9万人认为太难，有2.2万人认为难。认为太难的人数占了58.97%，认为难的人数占到了18.8%，两者合计77.77%，也就是说，超过2/3的投票人数，认为2020考研数学比较难。那么，今年的数学到底难在哪里？其实，通过分析大家的感受，不难发现，很多同学觉得难，不是在于题目有多偏，也不是在于题目有多新颖，出题套路也没有特别大的变化，乃至于很多同学都觉得，感觉题目都能看懂，就是算不出来。所以，真正的难度在于计算量大上，这与2016年有点相似，所以说，总体来说，数学二可能比2016年难，数学一、三可能比较接近。这对2021年以及今后考研的同学复习又有什么启发呢？启发肯定有，那就是：面对考研数学，没有任何捷径，唯有在掌握基础概念以及题型的基础上，不断去刷题，提高自己的计算能力，提高自己的做题速度。数学，是真正需要实力的，如果不注重计算能力以及做题速度的培养，到了考场上就会发现，什么“套路”、什么“花拳绣腿”，都完全不管用。所以说，对于考研数学，大家千万不要想着走捷径，也不要想着掌握多少“套路”，还是踏踏实实刷题，多练、多做，多总结。最后，既然数学已经考完了，大家就不要再去想，多想无益，再说大家都觉得难，那就是真的难，相信自己，没有什么大问题，分数线也肯定会有所下降。坚持考完最后一门专业课，尽可能将早上的损失补回来！感谢您的阅读，喜欢文章就点赞分享吧！

今天上午十一点过，2018年的重头戏——考研数学结束，许多下考场的同学都表示：难度太大！比2016年的题还要难！并且有很多同学都没做完试卷，或者说有时间也做不动！下面是考研数学辅导方面的专家——汤神先生关于2018年考研数学的评价：有些题出得有点冷，不要影响下午考试！不得不说，汤神是位敬业的好老师，他也很会做人，低调务实！在考完数学之余还不忘提醒广大考研人：不要再谈论结束的科目，好好为接下来的科目做准备！汤家凤谈2018考研数学题目当即就有同学抑制不住心中的那股痛劲儿，在汤老师下面回复了一个想要寻短见！汤老师似乎见得比较多了，赶紧进行语言上的开导。下面这位女同学难以忘记考场的情景，情不自禁地考试问老师一些考研数学卷上的题目。然而，那些过去了的是永远无法改变的了。在初试成绩中，能改变的只有下午的专业课了。数学1、2、3都难2018年的考研数学有多难？我想只有考场上的同学们最有发言权。上面有说数学二出题太冷了，也有同学说数学三的题目出得很偏，而且是两位同学已经是二战了，压力确实有些偏大。二战生在考研初期有绝对的优势，不过在考研后期可能没有应届生那样有第一次的迎考状态。2018年数学的难度大于2016？上面有同学提到，2018年考研数学的难度不亚于2016年。2016年的线性代数我想广大的研究生还有印象，那确实是令人无法抬笔！这位“翻滚吧我的小猪仔儿”同学说了一句令人心酸的话，五个月乘以每天八小时的数学复习时间，到头来竟然还是一场空？2016年的情况其实并没有大家想象中的那么惨，当年录取分数下降了！所以根据水涨船高的原理，2018年的考研数学单科线应该也会有所下降。祝考研学子：金榜题名！
