PART IV

READING COMPREHENSION

(45 minutes, 30 points, 1 point each)

Directions:In this part of the test, there are five short passages. Read each passage carefully, and

then do the questions that follow. Choose the best answer from the four choices given

and mark the corresponding letter with a single bar across the square brackets on your

machine-scored Answer Sheet.

Passage One

To improve everything from fuel economy to performance, automotive researchers are turning to ―mechatronics‖, the integration of mechanical systems with new electronic components and software control. Because lives will depend on such mechatronic systems, Rolf Isermann, an engineer in Germany, is using software that can identify and correct flaws in real time to make sure the technology functions perfectly.

In order to do mechatronic braking right, Isermann’s group is developing software that tracks data from three sensors: one detects the flow of electrical current to the brake actuator; a second tracks the actuator’s position; and the third measures its clamping force. Isermann’s software analyzes those numbers to detect faults and flashes a dashboard warning light, so the driver can get the car serviced before the fault leads to failure.

―I think people are now b ecoming aware electronic devices are safer than mechanical ones, for you can build in fault diagnoses and fault tolerance‖ says Karl Hedrick, a mechanical engineer.

Isermann is also working to make engines run cleaner. He is developing software that detects ignition problems. Because it’s not practical to have a sensor inside a combustion chamber, Isermann’s system relies on data from sensors that measure oxygen levels in exhaust and track the speed of the mechanism that delivers the engine’s force to whee ls. Tiny fluctuations in this speed accompanied by changes in emissions reveal failures of ignition, when the software can warn the driver or automatically fix the problem.

Partnerships with manufacturing companies merge the basic research with industry’s development of such technologies in actual cars. Isermann says that ―80 to 90 percent of the innovations in engines and cars these days are due to electronics and mechatronics.‖ Mechatronic systems were found mainly in aircraft and industrial equipment or in small precision components. But new applications in cars have increased the number of groups working on mechatronics. The trend has been fueled by falling prices for microprocessors and sensors, stricter vehicle-emissions regulations, and automakers’ w illingness to enhance their vehicles with additional comfort and performance features.

Although the luxury market looms largest today - new high-end models from BMW contain over 70 microprocessors that control more than 120 tiny motors - mechatronics will be moving into wider car markets within five years. With software like Isermann’s on board, the electronic veins of these new driving machines should be as sturdy and reliable as steel.

51. This passage is intended to describe the______.

A. various definitions of mechatronics

B. application of mechatronics to automobiles

C. problems with quality of cars and solutions

D. partnerships between engineers and auto makers

52. The underlined words ―fuel economy‖ in the first paragraph probably mean______.

B. is attracting fewer companies than before

C. is unlikely to make cars more comfortable

D. will be used more widely in auto manufacture

55. New models of BMW are mentioned to suggest that ______.

A. BMW cars are regarded as luxuries

B. mechatronics-based cars are quite fast

C. mechatronics is essential to BMW cars

D. mechatronics will raise the price of cars

Passage Two

Goldberg, a plant molecular biologist at the University of California, expresses despair at the persistent need to confront what he sees as false fears over the health risks of genetically modified (GM) crops. Particularly frustrating to himis that this debate should have ended decades ago, when researchers produced a stream of compelling evidence: ―Today we’r e facing the same objections we faced 40 years ago.‖

Across campus, David Williams, a cellular biologist, has the opposite complaint. ―A lot of naive science has been involved in pushing this technology,‖ he says. ―Thirty years ago we didn’t know that when you throw any gene into a different genome, the genome reacts to it. But now anyone in this field knows the genome is not a static environment. Inserted genes can be transformed by several different means, and it can happen generations later.‖ The result, he insists, could very well be potentially toxic plants slipping through testing.

Williams concedes that he is among a tiny minority of biologists raising sharp questions about the safety of GM crops. But he says this is only because the field of plant molecular biology is protecting its interests. Funding, much of it from the companies that sell GM seeds, heavily favors researchers who are exploring ways to further the use of genetic modification in agriculture. He says that biologists who point out health or other risks associated with GM crops—who merely report or defend experimental findings that imply there may be risks—find themselves the focus of vicious attacks on their credibility, which leads them to keep quiet.

Whether Williams is right or wrong, one thing is undeniable: despite overwhelming evidence that GM crops are safe, the debate over their use isgrowing louder. Proponents say the technology is the only way to feed a warming, increasingly populous world. Critics claim we interfere with

nature at our peril.Skeptics would argue that this debate is a good thing—that we cannot be too cautious when coping with the genetic basis of food supply. To researchers such as Goldberg, however, the persistence of fears about GM foods is nothing short of irritating. ―Despite millions of genetic experiments involving every type of organism on earth,‖ he says, ―and people eating billions of meals without a problem, we’ve gone back to being ignorant.‖

So who is right: advocates of GM or critics? Only time can answer you.

57. Goldberg is convinced that GM crops______.

A. pose a risk to health

B. are quite safe to eat

C. should be subject to criticism

D. are worth questioning

58. David Williams raises concerns about ______.

A. the potential toxicity of GM crops

B. the reliability of genome research

C. the future development of genetics

D. the verified toxicity of GM crops

59. Paragraph Three is focused on ______.

A. how biology companies protect their own interests

B. why Williams raises sharp questions about GM crops

C. who points out problems associated with GM crops

D. what the majority of biologists think of GM crops

60. It can be concluded from Paragraph Four that ______.

A. critics of GM foods outnumber proponents

B. more people will stop consuming GM foods

C. the debate over the use of GM foods will continue

D. people are ignorant of the safety of GM foods

61. The underlined words in Paragraph Four probably mean ______.

A. far from irritating

B. anything but irritating

C. a little bit irritating

D. absolutely irritating

62. This passage aims to describe______ genetically modified foods.

A. the benefits of

B. the controversy about

C. the prospects of

Passage Three

Historians of the American civil war find themselves in the same unenviable position as Shakespeare scholars: so thoroughly have their fields of study been explored that finding a nearly virgin corner is all but impossible. But Don Doyle has broken new ground in an enlightening and compellingly written book, ―The Cause of All Nations‖. More than any previous study, it tells the story of how America’s civil war was perceived, debated a nd reacted to abroad, and how that reaction shaped the course of the war at home.

At the war’s outset, however, things were not so simple. Southern diplomats framed their struggle in accordance with liberal principles of self-determination. They judged the conflict, Mr Doyle notes, to be ―one arising naturally between industrial and agricultural societies, not freedom and slavery as the North believed.‖The North’s response, meanwhile, was uncompromising, legalistic and violent. America’s secretary of state threatened to ―wrap the whole world in flames‖, promising total war on any state that dared aid the South.

Most histories of the civil war turn inward at the end and examine the war’s consequences and legacy for America. Mr Doyle turns outward to show how important America’s civil war was to the rest of the world: liberty and democracy defeated slavery and the landed gentry.

The Union’s victory had wider impacts. In Spain, Queen Isabella, fearing American naval power, ended the attempted re-colonization of Santo Domingo. Ulysses Grant, a civil-war general, turned his military attention to Mexico, where Napoleon III had installed an Austrian, Maximilian, as emperor. When the threat of an alliance between France and the South was smashed, Napoleon withdrew his support and in 1867 Maximilian was executed by Mexican troops. Across the ocean, Britain’s republicans marched to victory that same year. Democracy had not just survived, but flourished.

After Lincoln’s death, a French newspaper wrote that he ―represente d the cause of democracy in the largest and the most universal understanding of the word. That cause is our cause, as much as it is that of the United States.‖ In honor of the Union’s victory a French artist crafted a statue out of copper sheeting, a figure representing freedom, tall and proud, holding a torch high. The Statue of Liberty stands today in New York harbor, the copper now green with age, her gaze fixed across the Atlantic on Europe.

63. Shakespeare is mentioned in the first paragraph to illustrate that________.

A. historians of the civil war should learn from Shakespeare

B. new discoveries are easy concerning the cause of the civil war

C. the civil war has been studied as extensively as possible

D. the civil w ar and Shakespeare’s works are known worldwide

64. The book entitled ―The Cause of All Nations‖ is focused on ______.

A. the impact of the civil war on other countries

B. factors that caused the outbreak of the civil war

C. the political difference between the North and South

D. the consequences of the civil war for America

65. The North regarded the civil war as a war ______.

A. between industrial and agricultural states

B. between slaves and slave-owners

C. between freedom and slavery

D.between the government and people

66. Paragraph Four is mainly concerned with ______.

A. the effect of incidents abroad on the civil war

B. contributions of Europeans to the Union’s victory

C. numerous conflicts between European countries

D. effects of the Union’s victory on other countries

67. According to this passage, which of the following statements is true?

A. The author of this passage thinks highly of this book by Don Doyle.

B. The Statue of Liberty was crafted in honor of Abraham Lincoln.

C. The North won the civil war with the support from Europe.

D. The civil war was caused by French diplomatic policies.

68. This passage is probably a ______.

A. personal letter

B. research paper

C. book review

D. fairy tale

Passage Four

Most people under 30 consider email an outdated mode of communication used only by ―old people‖. Instead, they text or post to Facebook. They attach documents, photos, videos, and links to their text messages and Facebook posts the way people over 30 do with email. Many people under 20 now see Facebook as a medium for the older generation.

For them, texting has become the primary mode of communication. It offers privacy phone calls don’t and immediacy email can’t. Crisis hotlines have begun accepting ca lls from at-risk youth via texting with two big advantages: they can deal with more than one person at a time, and pass the conversation on to an expert without interrupting the conversation.

However, texting discourages thoughtful discussion or detail. Addictive problems are compounded by texting’s immediacy. Emails take some time and they require that you take the step of explicitly opening them. Text messages magically appear on the screen and demand immediate attention. Add to that the social expectation that an unanswered text feels insulting to the sender, and you’ve got a recipe for addiction: you receive a text, which activates your novelty center s. You respond and feel rewarded. ―More! More! Give me more!‖

In a famous experiment, neuroscientists placed a small electrode in the brains of rats, in a region known as the pleasure center that ―lights up‖ when gamblers win a bet or drug addicts take cocaine. A lever in the cage allowed the rats to send a small electrical signal directly to this center. Boy how they did! They liked it so much that they did nothing else. They forgot all about eating and sleeping. Long after they were hungry, they ignored tasty food if they had a chance to press that little bar. The rats just pressed the lever over and over again until they died of starvation and exhaustion.

Each time we dispatch a text message, we feel a sense of accomplishment, and our brain gets a small amount of reward hormones telling us we accomplished something. Each time we check a Twitter feed or Facebook update, we encounter something novel and feel more connected socially and get more reward hormones. But remember, it is the dumb, novelty-seeking portion of the brain that induces this feeling of pleasure, not the planning, scheduling, higher-level thought centers in the brain. You can now decide for yourself whether email-, Facebook- and Twitter-checking constitute a neural addiction.

69. The most popular mode of communication for those under 20 is ______.

A. email

B. Facebook

C. texting

D. phone calls

70. Paragraph Three is focused on ______.

A. advantages of email over text messages

B. addiction and immediacy caused by texting

C. benefits of sending text messages

D. the need to answer a text message

71. An experiment is mentioned in Paragraph Four as evidence that______.

A. rats enjoy playing electronic games

B. animals are mal-treated in a laboratory

C. rats are too stupid to survive an experiment

D. addiction or obsession can be fatal

72. It seems to the author that the sense of accomplishment ______.

A. is of health benefit to humans

B. can induce reward hormones

C. mainly depends on email alone

D. helps overcome addiction

73. The author of this passage believes that checking email, Twitter and Facebook ______.

A. can help maintain social relations

B. contributes to planning and thought

C. may induce a neural addiction

D. can expose you to something novel

74. This passage is intended to ______.

A. discourage the use of cell phones

B. tell us to stop using email if possible

C. describe adverse effects of texting

D. tell us how to prevent addiction to texting

Passage Five

I’m writing this after hearing the apparently encouraging news that a new lung cancer treatment is capable of giving sufferers a possible ―extra 200 days‖ of life. Another morning, another ―battle against cancer‖ fought, and in this case won – sort of.

Yet I find myself rather in sympathy with the one in five Dutch doctors who, it was reported this week, would consider helping someone die even if they had no physical problems but were ―tired of living‖. Because these doctors have the maturity to face the fact that life has a natural end.

The weary truth is that there are just so many ―battles‖, and they appear to be multiplying all the time. A new drug to treat strokes.A breakthrough in the ―war‖ against heart disease. We are fed, daily, the hopeful news: fatal disease is slowly on the retreat. But there’s always one more, and sooner or later we all lose.

An extra 200 days for lung cancer sufferers. I found myself wondering – what kind of days? Of course, all days may seem worth living when death is approaching. But sometimes the endless quest to extend our days seems fruitless. In the constant narratives of ―triumphs‖ over disease, we are not engaged in a struggle against disease, but death itself. We are only partially rational beings – and at the non-rational level, we believe medicine will save us from our fates.

Most cancers are driven by random mistakes in cell division that are outside our control. Yet for many the thought won’t quite go away. Thus, we are never quite at peace, because we are

always working hard to keep our eyes from staring at the sun. We immerse ourselves in trivial distractions – shopping, loud music, flashing lights.

My father died at age 87, and my regret about his death is that he didn’t die a few months sooner. The clinging on to lifemeant that eventually he died unable to speak or hear, totally cut off from the world. A lonely hospital death that had it been faced earlier, could have been altogether more human. The battle against mortal disease can never be won because it is a battle against the inevitable. To face our fate is to have the courage to live, even if it means dying a little earlier than the experts, and even our families, might – perhaps with more kindness than wisdom – insist.

75. The author is likely to be ______ the type of news mentioned in the first paragraph.

A. disinterested in

B. encouraged by

C. curious about

D. surprised with

76. It can be inferred from the third paragraph that the author______.

A. doesn’t believe in these battles against fatal diseases

B. is convinced that deadly diseases will become curable

C. is excited about the advances in the medical science

D. finds the battles against fatal diseases are decreasing

77. It seems to the author that the extra 200 days for patients of lung cancer are______.

A. really worth living

B. not really worth living

C. of inestimable value

D. a medical miracle

78. Paragraph Five implies that many people ______.

A. love fighting

B. are very busy

C. are very lazy

D. fear death

79. The author mentions his father in the last paragraph to ______.

A. prove that most people die miserable at old age

B. show his father’s courage to face up to death

C. argue that sometimes earlier death means less pain

D. reveal his intense sadness over his father’s death

80. The author’s purpose in writing this passage is to______.

A. remind us that doctors are more kind than wise

B. tell people to learn to face death with courage

C. encourage mortal patients to prolong their lives

D. advise patients of cancer to give up medication

If humans are capable of sacrificing collective benefit in the name of stabilizing an economic system that renders daily life more expensive, then humans will be able to make important lifestyle changes in the interest of stabilizing the physical systems upon which all of life depends. Many of the changes that need to be made to dramatically cut emissions would substantially improve the quality of life for the majority of people –from allowing kids in Beijing to play outside without wearing pollution masks to creating good jobs in clean energy sectors for millions. We could commit ourselves to radically cutting our fossil fuel emissions and beginning the shift to zero-carbon sources of energy based on renewable technology.

统计学考研真题

2012年统计学考研真题统计学考研题目去年的真题有两道题朝纲了后来老师说他都不知道有考纲这一回事，所以今年应该是要严格按照大纲来出（一）五道问答题 1.两地区的什么比例（好像是收入的均值吧），运用t检验得出p值为0.132，据此能否得出这两个地区的均值相等的结论？【分析】首先从前提假设来看，题目中没有给出假设条件，如果用t检验的话，需要的假设条件有 1、两个总体正态分布２、总体方差未知３、两个总体的样本独立抽取（否则为匹配样本）４、小样本（ｎ<30） 5、每一个总体样本内部也相互独立（否则为有限总体情况）题目中除了假设条件没有以外，还缺少为判断标准的显著水平a，如果a>0.132则还是要拒绝原假设的。如果还要写可以加上原假设未写明。 2.在参数统计中，卡方分布有哪些应用，并举例说明【分析】在参数统计中，卡方分布有时序：检验白噪声的lb统计量、q统计量检验异方差相关性的Q统计量、lm统计量 GARCH模型六部最后一步检验正态性的偏度峰度服从自由度为2的开放分布；多元：wills统计量（就是多元中的F统计量）当不满足n、p的情况时就为卡方分布。典型相关分析中检验典型相关系数的卡方分布。多元中两个总体均值的假设检验，只要两个总体中最小的总体的数目趋于无穷则也服从卡方分布。统计学：单个总体的方差假设检验或者是参数估计也服从卡方分布。（有人说还有列联分析中拟合优度和独立性检验，不过我认为列联分析根本就不属于参数统计，列联分析是非参数统计的内容，所以这两个不能写入，其实多元中还有一个和马氏距离非常相似的公式也服从卡方分布，但是这台机子上没法打出符号，就请各位童鞋自己注意一下） 3.贝叶斯统计与经典统计的区别【分析】贝叶斯统计的思想是假如对某一个总体有一定的了解，那么用先验分布来描述这种认识，然后从总体中抽取样本，用样本来修正这种认识得到后验分布，以后的推断通过都通过后验分布进行。经典统计分描述统计和推断统计，其中描述统计是将数据通过图表进行分析，而推断统计则是直接通过样本来描述总体，并未涉及先验分布。 4.时间序列的弱平稳的含义【分析】这个题目书上有，就不写了。

拿下非全日制研究生政治考试只需要这两点

拿下考研政治只需要这两点很多人私信小编问“2018年的政治研究生”的题型包括哪些方面，小编为了满足大家，就为大家实力分析一波，其实答案已经初见端倪，只是大家没有注意到，那我们就结合今年的考题看看是不是这样的。纵观2017年的一月研究生整套试卷，一个最突出的特点，就是紧扣社会热点、围绕学科重点。下面我们就结合真题来看一下是不是这样。对于2016年来说，热点问题有很多：五大发展理念、供给侧改革、十八届六中全会、中国共产党成立95周年、长征胜利80周年、孙中山诞辰150周年、“一带一路”、农村土地制度的改革、G20等等，这些热点在试卷上基本都有体现。比如第6题考查的就是供给侧改革的目的;第8题就考查了农村土地制度的改革;第22题考查到了中国共产党成立95周年习近平讲话;第23题考查到了“一带一路”;第25题考查了五大发展理念;第26题考查十八届六中全会关于从严治党的问题;第28题考查了孙中山诞辰150周年;第36题考查了长征胜利80周年，如何理解长征永远在路上;第38题考查了G20杭州峰会;等等。所以，考研政治一定是迎着热点上的。那么对于要准备2018年考研的学生来说，明年复习的重点仍旧是围绕当年发生的重大事件去做准备，其中的重要考点及如何结合社会热点去做准备，我们会在万学海文的各种课程里给大家一网打尽。对于重点问题，2017考研政治也没有回避。比如马原理考查的就是马克思主义哲学的重点——认识论;毛中特考查的就是五位一体布局中的经济建设和“四个全面”;近现代史考查的就是中国共产党的探索史;思修法基考查的是思修

中的重点——思想修养和道德修养。所以对要准备2018年考研的学生来说，明年复习的重点除了热点问题以外，就是每一门课程的重点部分。下面我就对各门课程的重点做一简介：马克思主义基本原理主要包括马克思主义哲学、政治经济学和科学社会主义三部分。重点是马克思主义哲学，它又包括四大板块：唯物论、辩证法、认识论、唯物史观。重点是辩证法和认识论，因为这两部分是出分析题的重点。辩证法部分的内容历年都是命题的密集区，考点最多，在各种类型题中都出现过;其中“对立统一规律”是历年命题的重中之重，从2006年一直到2012年连续7年分析题都考“对立统一规律”。认识论的重点是“实践和认识”、“真理和价值”，也是经常命制选择和分析题的。毛中特的重点是第八章中国特色社会主义建设理论，又叫“五位一体”理论，主要包括建设中国特色社会主义经济、建设中国特色社会主义政治、建设中国特色社会主义文化、建设社会主义和谐社会、建设社会主义生态文明。这几年毛中特部分的分析题主要是从这部分命制，如2015年考查的是基本经济制度，2016年考查的生态文明，2017年考查的是经济建设的精准扶贫。而且在考研政治的五大学科中毛中特是与中央精神联系得最紧密的学科，所以同学们在备考的时候一定要紧跟习近平及其重要讲话，答题的时候一定要紧扣中央精神。近现代史纲要的重点是第四章到第七章，是中国共产党领导中国人民的探索抗争，最后取得民族独立和人民解放的过程，是最能体现历史纲要命题主旨的内容。历史纲要命题主旨就是历史和人民为什么最终选择马克思主义、为什么选择
