(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. For Questions 41-45, choose the most suitable one from the fist A-G to fit into each of the numbered blanks. There are two extra choices, which do not fit in any of the gaps. Mark your answers on ANSWER SHEET. (10 points)[A] Eye fix actions are brief[B] Too much eye contact is instinctively felt to be rude[C] Eye contact can be a friendly social signal[D] Personality can affect how a person reacts to eye contact[E] Biological factors behind eye contact are being investigated [F] Most people are not comfortable holding eye contact with strangers[G] Eye contact can also be aggressive.In a social situation, eye contact with another person can show that you are paying attention in a friendly way, But it can also be antagonistic such as when a political candidate turns toward their competitor ring a debate and makes eye contact that signals hostility.Here's what hard science reveals about eye contact: We know that a typical infant will instinctively gaze into its mother's eyes, and she will look back. 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. C Eye contact can be a friendly social signal42.E Biological factors behind eye contact are being investigated43.G Eye contact can also be aggressive44.A Eye fixactions are brief45.D Personality can affect how a person reacts to eye contactPart CDirections: Read the following text carefully and then translate the underlined segments into Chinese. Your translation should be written neatly on the ANSWER SHEET. (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

考研真题 2020年华中师范大学教育硕士考研真题分析

对于真题考试题型不固定的院校应该如何复习?文都比邻带来20年华中师范大学教育硕士考研真题分析。每年考研初试结束之后我们会对历年真题进行收集整理并进行详细的分析,为了提供给考生们提供更多备考资料。一、院系解读华中师范大学是教育部直属重点综合性大学,是“211工程”、“985工程优势学科创新平台”重点建设院校,是国家教育部本科教学评估“优秀”高校、国家师范生免费教育试点高校。学校2005年进入“211工程”重点建设高校名单,2017年入选国家“双一流”世界一流学科建设高校名单,2019年入选首批国家教材建设重点研究基地。华中师范大学教育学院形成了从本科生到博士后完整的人才培养体系。现有教育学、学前教育和特殊教育三个本科专业,其中教育学专业被评为湖北省本科品牌专业,也是教育部、财政部批准的高等学校特色专业建设点;学前教育专业属国家卓越幼儿园教师培养计划改革项目和湖北省专业综合改革试点;特殊教育专业属湖北省荆楚卓越计划改革项目。二、华中师范大学教育硕士考研参考书目三、考研真题分析(一)题型变化【文都比邻解读】华中师大333真题的题型不固定,时而会增加选择题,时而又全是主观题。例如,2012年只以“名词解释、简答题、论述题”三种形式考查,但2013年、2014年增加了选择题题型,2015年、2016年继续回归传统题型即名词解释、简答题和论述题,之后2017年又增加了选择题,而2018年又继续回归传统题型即名词解释、简答题和论述题,2019年又添加了选择题,2020年呈现的仍是传统的三大题型(即名词解释、简答题和论述题)。(二)科目分值按题型分布明细表(2020)【文都比邻解读】通过分析华中师范大学真题,可知:华中师范大学333教育专硕综合试题中,每个科目对应的分值较为固定。其中,教育学原理的分值比重最大且波动幅度最小,约为60分;教育心理学和中国教育史的比重稍大于外国教育史,但同时外国教育史的分值比重也在上升。(三)命题规律1.题量相对较少,答题时间很宽裕,且简答题题量相对固定。2.名词解释题中,2020年真题与2018、2019年相比,未考查到教育心理学的相关内容。其他三门科目均考查了2道题目,且题目较为常规,容易作答。3.简答题中,题目的难度系数中等。“赫尔巴特的课程论”“不同归因对学生有什么影响,如何指导学生正确归因”等不能直接作答,需要整合所学知识点进行作答,有一定难度。4.论述题中,题目的难度系数在整个试卷中最大。作答此类题目既需要掌握知识的宏观框架,也需要对具体的知识点进行准确记忆。比如,“论述新文化教育思潮(写任意五个)”,既要对新文化教育思潮的整体内容有所了解,又要能够准确写出每一个教育思潮的相关知识点。(四)复试建议1.尽早核对答案,进行估分。2.尽早规划复习时间,准备复试,赢在起跑线上。3.切记按照复试指定书目进行复习。四、真题早知道2020年真题(部分)一、名词解释:每题5分,共30分4.社学6.现代人文主义教育思潮二、简答:每题10分,共40分3.赫尔巴特的课程论4.不同归因对学生有什么影响,如何指导学生正确归因三、分析论述题:每题20分,共80分1.结合教育实际,德育过程培养学生知情意行发展过程。4.分析论述信息加工学习理论及其对教学的启示。

找不到考研真题,复习毫无方向,那些读研的人是如何获得真题的?

找不到考研真题,复习毫无方向,那些读研的人是如何获得真题的?对于每一位打算考研的同学来说,备考之前最让人头疼的就是如何获得报考院校的历年考研真题!毫无疑问的是,历年真题的重要性特别大,考过研的同学都深有体会!那些专业课考到140以上的学霸肯定都是把考研真题研究透彻的同学,但是没有考研真题的话复习不得法,考不到高分,很可能考研失败!那么,在哪里找考研历年真题呢?那些读研的人是如何获得考研资料的?部分院校已不提供考研历年真题,别走弯路,获得真题的好方法在此近几年考研热度居高不小,部分院校已经不再提供考研历年真题,很多同学在考研备考阶段走了很多弯路,就是因为没有真题在手,复习的特别盲目,到最后也没考高分,也没读研。小水在这里结合自身考研的经验,给大家分享一下获得考研历年真题的渠道,想读研的同学请牢记!01、直接去目标院校购买虽然大部分的院校已经不提供考研历年真题,但是还有一些学校会提供一年的考研真题,也就是去年刚考过的那一届真题。不过,你要去学校的研招办询问,他们会直接告诉你是否有。如果你本身不方便,可以找目标院校的学生帮忙打印并邮寄!02、准研究生学姐或学长那获得相比于上面的方法,这个方法可谓是最靠谱的了。无论是考上还是没考上的同学,他们那里大都会有目标院校的考研真题。这里为何要单独强调准研究生呢?主要是他们刚考上,肯定有考研真题在手,而且是考上研究生的,对于真题和复试都有自己的见解,如果此刻结交了,在你进入考研复试的时候也能对你有很大的帮助!不过,对于准研究生来说,他们的资料不是那么好获得的,一般都需要花钱才能做到,毕竟考上研究生的人不会轻易将资料免费送你的。这里注意区别真假,有的骗子就是冒充学长学姐骗钱的,同学们注意!03、网上搜索回忆版现在网络比较发达,很多读研的同学会把考研真题和经验分享到网上,这个时候考生可以根据自己掌握的信息区分。考研真题哪怕是回忆版都比没有强!因为有了真题在手,你复习也有一个方向,再结合考研参考书目的话,基本上就是成功了一半!04、网上多渠道购买对于考研真题,很多人都知道它的重要性,所以网上有很多机构就是卖真题赚钱的。当然也有一些正规的渠道可以购买,考生要注意区分,购买的资料有真有假,需要你结合自身报考的学校分辨才行!以上是大部分读研的同学获得考研真题的方法,找不到真题的同学可以试试。当然,你如果遇到一些比较好心的学长或学姐,如小水这样的,有考研真题是会直接无偿给予的,不过你也得是那位有缘人才行。你还知道其他搜集考研真题的渠道吗?欢迎留言分享您的观点!
