北京大学考博英语真题常见从句及其解析

北京大学考博英语真题常见从句及其解析复合句——形容词性(定语)从句：定语从句的测试重点：选择正确的关系代词或关系副词。

切记：关系代词/副词一定要在从句中充当某种成分，即主语、宾语、表语或定语。

指人时用who(做主语)、whom(做宾语)、whose(做定语);指物时用which或that;指时间用when;指地点用where;指原因用why。

此外还要注意如下几个问题：需要各大院校历年考博英语真题及其解析请加扣扣七七二六七八五三七或二八九零零六四三五一，也可以拨打全国免费咨询电话四零零六六八六九七八享受考博辅导体验。

1.尤其要注意whose的用法whose在从句中做定语，修饰名词。

所以，如果关系代词后面紧接的是名词，且关系代词又不在从句中做主语或宾语，那么，这个关系代词就应该是whose。

如：Of course developing a system for helping students whose needs are out of the ordinary had been a necessary step in helping those students get into the world of public education.It is perhaps not an exaggeration to say that we shall soon be trusting our health,wealth and happiness to elements with whose very names the general public are unfamiliar.2.介词+which的用法如果从句中主宾成分齐全，考生便可考虑关系代词是否在从句中做状语，而状语通常用介词短语充当，于是可以得知，关系代词前面应有介词，再分析所给的选项，根据与名词的搭配作出正确选择。

如：Children are best served when schools contribute to shaping thesolid foundation on which their future will be built.However,the batteries from which they(electric vehicles)draw energy usually contain harmful chemicals,which become pollutants when the batteries are disposed of.We are not conscious of the extent to which work provides the psychological satisfaction that can make the difference between a full and an empty life.3.非限定性定语从句前面有逗号标志，按汉语习惯通常翻译成两个句子切记：与汉语不同的是，英语中两个句子之间一般说来不能用逗号断开，而要用适当的连词或关系代词使它们形成从属或并列关系。

Mark your answers on the Answer Sheet.2023 was the worst year for the record labels in a decade31 was 2023, and before that 2023 and 2023. In fact,industry revenues have been 32 for the past 10 years. Digital sales are growing, but not as fast as traditional sales are falling.Maybe that’s because illegal downloads are so easy. People have been 33 intellectual property for centuries, but it used to be a time-consuming way to generate markedly 34 copies. These days, high-quality copies are 35. According to the Pew Internet project, people use file-sharing software more often than they do iTunes and other legal shops.I’d like to believe, as many of my friends seem to, that this practice won’t do much harm. But even as I’ve heard over the past decade that things weren’t 36 bad, that the music industry was moving to a new, better business model, each year’s numbers have been worse. Maybe it’s time to admit that we may never find a way to 37 consumers who want free entertainment with creators who want to get paid.38 on this problem, the computational neuroscientist Anders Sandberg recently noted that although we have strong instinctive feelings about ownership, intellectual property doesn’t always 39 that framework. The harm done by individual acts of piracy is too small and too abstract.“The nature of intellectual property,”he wrote, “makes it hard to maintain the social and empathic 40 that keep(s) us from taking each other’s things.”31.

A. constraints B. consciousness C. norm D. etiquettePart IV: Reading Comprehension(20%)Directions: Each of the following four passages is followed by some questions or unfinished statements. For each question or unfinished statement, four answers are given. Read the passages carefully and choose the best answer to each question. Mark your choices on the Answer Sheet.Passage OneCancer has always been with us, but not always in the same way. Its care and management have differed over time, of course, but so, too, have its identity, visibility, and meanings. Pick up the thread of history at its most distant end and you have cancer the crab—so named either because of the ramifying venous processes spreading out from a tumor or because its pain is like the pinch of a crab’s claw. Premodern cancer is a lump, a swelling that sometimes breaks through the skin in ulcerations producing foul-smelling discharges. The ancient Egyptians knew about many tumors that had a bad outcome, and the Greeks made a distinction between benign tumors (oncos) and malignant ones (carcinos). In the second century A．D．, Galen reckoned that the cause was systemic, an excess of melancholy or black bile, one of the body’s four “humors,”brought on by bad diet and environmental circumstances. Ancient medical practitioners sometimes cut tumors out, but the prognosis was known to be grim. Describing tumors of the breast, an Egyptian papyrus from about 1600 B．C．concluded: “There is no treatment.”The experience of cancer has always been terrible, but, until modern times, its mark on the culture has been light. In the past, fear coagulated around other ways of dying: infectious and epidemic diseases (plague, smallpox, cholera, typhus, typhoid fever); “apoplexies”(what we now call strokes and heart attacks); and, most notably in the nineteenth century, “consumption”(tuberculosis). The agonizing manner of cancer death was dreaded, but that fear was not centrally situated in the public mind—as it now is. This is one reason that the medical historian Roy Porter wrote that cancer is “the modern disease par excellence,”and that Mukherjee calls it “the quintessential product of modernity.”At one time, it was thought that cancer was a “disease of civilization,” belonging to much the same causal domain as “neurasthenia” and diabetes, the former a nervous weakness belie ved to be brought about by the stress of modern life and the latter a condition produced by bad diet and indolence. In the eighteenth and nineteenth centuries, some physicians attributedcancer—notably of the breast and the ovaries—to psychological and behavioral causes. William Buchan’s wildly popular eighteenth-century text “Domestic Medicine”judged that cancers might be caused by “excessive fear, grief, religious melancholy.”In the nineteenth century, reference was repeatedly made to a “cancer personality,”and, in some versions, specifically to sexual repression. As Susan Sontag observed, cancer was considered shameful, not to be mentioned, even obscene. Among the Romantics and the Victorians, suffering and dying from tuberculosis might be considered a badge of refinement; cancer death was nothing of the sort. “It seems unimaginable,”Sontag wrote, “to aestheticize”cancer.41. According to the passage, the ancient Egyptians .A. called cancer the crabB. were able to distinguish benign tumors and malignant onesC. found out the cause of cancerD. knew about a lot of malignant tumors42. Which of the following statements about the cancers of the past is best supported by the passage?A. Ancient people did not live long enough to become prone to cancerB. In the past, people did not fear cancerC. Cancer death might be considered a badge of refinementD. Some physicians believed that one s own behavioral mode could lead to cancer43. Which of the following is the reason for cancer to be called “the modern disease”?A. Modern cancer care is very effectiveB. There is a lot more cancer nowC. People understand cancer in radically new ways nowD. There is a sharp increase in mortality in modern cancer world44.“Neurasthenia”and diabetes are mentioned because .A. they are as fatal as cancerB. they were considered to be “disease of civilization”C. people dread them very muchD.they are brought by the high pressure of modern life45. As suggested by the passage, with which of the following statements would the author most likely agree?A. The care and management of cancer have development over timeB. The cultural significance of cancer shifts in different timesC. Cancer s identity has never changedD. Cancer is the price paid for modern lifePassage TwoIf you happened to be watching NBC on the first Sunday morning in August last summer, you would have seen something curious. There, on the set of Meet the Press, the host, David Gregory, was interviewing a guest who made a forceful case that the U．S．economy had become “very distorted.”In the wake of the recession, this guest explained, high-income individuals, large banks, and major corporations had experienced a “significant recovery”; the rest of the economy, by contrast—including small businesses and “a very significant amount of the labor force”—was stuck and still struggling. What we were seeing, he argued, was not a single economy at all, but rather “fundamentally two separate types of economy,”increasingly distinct and divergent.This diagnosis, though alarming, was hardly unique: drawing attention to the divide between the wealthy and everyone else has long been standard fare on the left. (The idea of “two Americas”was a central theme of John Edwards’s 2023 and 2023 presidential runs.) What made the argument striking in this instance was that it was being offered by none other than the former five-term Federal Reserve Chairman Alan Greenspan: iconic libertarian, preeminent defender of the free market, and (at least until recently) the nation’s foremost devotee of Ayn Rand. When the high priest of capitalism himself is declaring the growth in economic inequality a national crisis, something has gone very, very wrong.This widening gap between the rich and non-rich has been evident for years. In a 2023 report to investors, for instance,three analysts at Citigroup advised that “the World is dividing into two blocs—the Plutonomy and the rest”.In a plutonomy there is no such animal as “the U．S．consumer”or “the UK consumer”, or indeed “the Russian consumer”. There are rich consumers, few in number, but disproportionate in the gigantic slice of income and consumption they take. There are the rest, the “non-rich”, the multitudinous many, but only accounting for surprisingly small bites of the national pie.Before the recession, it was relatively easy to ignore this concentration of wealth among an elite few. The wondrous inventions of the modern economy—Google, Amazon, the iPhone broadly improved the lives of middle-class consumers, even as they made a tiny subset of entrepreneurs hugely wealthy. And the less-wondrous inventions—particularly the explosion of subprime credit—helped mask the rise of income inequality for many of those whose earnings were stagnant.But the financial crisis and its long, dismal aftermath have changed all that. A multi-billion-dollar bailout and Wall Street’s swift, subsequent reinstatement of gargantuan bonuses have inspired a narrative of parasitic bankers and other elites rigging the game for their own benefit.And this, in turn, has led to wider-and not unreasonable-fears that we are living in not merely a plutonomy, but a plutocracy, in which the rich display outsize political influence, narrowly self interested motives, and a casual indifference to anyone outside their own rarefied economic bubble.46. According to the passage, the U．S．economy .A. fares quite wellB. has completely recovered from the economic recessionC. has its own problemsD. is lagging behind other industrial economies47. Which of the following statement about today’s super-elite would the passage support?A. Today’s plutocrats are the hereditary eliteB. Today’s super-rich are increasingly a nation unto themselvesC. They are the deserving winners of a tough economic competitionD. They are worried about the social and political consequences of rising income inequality48. What can be said of modern technological innovations?A. They have lifted many people into the middle class.B. They have narrowed the gap between the rich and the non-rich.C. They have led to a rise of income inequality.D. They have benefited the general public.49. The author seems to suggest that the financial crisis and its aftermath .A. have compromised the rich with the non-richB. have enriched the plutocratic eliteC. have put Americans on the alert for too much power the rich possessD. have enlarged the gap between the rich and non-rich50. The primary purpose of the passage is to .A. present the financial imbalance in the U．S．B. display sympathy for the working classC. criticize the super elite of the Unite StatesD. appreciate the merits of the super rich in the U．S．Passage ThreeCharles Darwin’s “On the Origin of Species”is credited with sparking evolution’s revolution in scientific thought, but many observers had pondered evolution before him. It was understanding the idea’s significance and selling it to the public that made Darwin great, according to the Arnold Arboretum’s new director.William Friedman, the Arnold Professor of Organism and Evolutionary Biology who took over as arboretum director Ja n．1, has studied Darwin’s writings as well as those of his predecessors and contemporaries. While Darwin is widely credited as the father of evolution, Friedman said the “historical sketch”that Darwin attached to later printings of his masterpiece wasintended to mollify those who demanded credit for their own earlier ideas.The historical sketch grew with each subsequent printing, Friedman told an audience Monday (Ja n．10), until, by the 6th edition, 34 authors were mentioned in it. Scholars now believe that somewhere between 50 and 60 authors had beaten Darwin in their writings about evolution Included was Darwin’s grandfather, Erasmus Darwin, a physician who irritated clergymen with his insistence that life arose from lower forms, specifically mollusks.Friedman’s talk, “A Darwinian Look at Darwin’s Evolutionist Ancestors,”took place at the arboretum’s Hunnewell Building and was the first in a new Director’s Lecture Series.Though others had clearly pondered evolution before Darwin, he wasn’t without originality.Friedman said that Darwin’s thinking on natural selection as the mechanism of evolution was shared by few, most prominently Alfred Wallace, whose writing on the subject after years in the field spurred Darwin’s writing of “On the Origin of Species.”Although the book runs more than 400 pages, Friedman said it was never the book on evolution and natural selection that Darwin intended. In 1856, three years before the book was published, he began work on a detailed tome on natural selection that wouldn’t see publication until 1975.The seminal event in creating “On the Origin of Species”occurred in 1858, when Wallace wrote Darwin detailing Wallace’s ideas of evolution by natural selection. The arrival of Wallace’s ideas galvanized Darwin into writing “On the Origin of Species”as an “abstract”of the ideas he was painstakingly laying out in the larger work.This was a lucky break for Darwin, because it forced him to write his ideas in plain language, which led to a book that was not only revolutionary, despite those who’d tread similar ground before, but that was also very readable.Though others thought about evolution before Darwin, scientific discovery requires more than just an idea. In addition to the concept, discovery requires the understanding of the significance of the idea, something some of the earlier authors clearly did not have—such as the arborist who buried his thoughts on natural selection in the appendix of a book on naval timber. Lastly, scientific discovery demands the ability to convince others of the correctness of an idea.Darwin, through “On the Origin of Species,”was the only thinker of the time who had all three of those traits, Friedman said.“Darwin had the ability to convince others of the correctness of the idea,” Friedman said, adding that even Wallace, whose claim to new thinking on evolution and natural selection was stronger than all the others, paid homage to Darwin by titling his 1889 book on the subject, “Darwinism.”51. According to William Friedman, Darwin’s “On the Origin of Species”is great in that.A. it was the most studied by later scientistsB. it had significant ideas about evolutionC. it was the first to talk about evolutionD. it was well received by the public52. Friedman believes that Darwin attached a “historical sketch”to later printings of his book in an attempt to .A. credit the ideas about evolution before hisB. claim himself as the father of evolutionC. introduce his grandfather to the readerD. summarize his predecessors work53. In Friedman s view, Darwin s originality lies in .A. his thinking on natural selection as the mechanism of evolutionB. his sharing ideas about evolution with his contemporariesC. the way he wrote “On the Origin of Species”D. the way he lectured on the ideas of evolution54. We have learned that at first Darwin intended to write his idea in .A. a much larger bookB. a 400page bookC. scientific termsD. plain language55. Scientific discovery requires all the following Expect .A. coming up with a new ideaB. understanding the significance of the ideaC. making claims to the idea by writing booksD. convincing others of the correctness of the idesPassage FourMany adults may think they are getting enough shut-eye, but in a major sleep study almost 80 percent of respondents admitted to not getting their prescribed amount of nightly rest. So, what exactly is the right amount of sleep? Research shows that adults need an average of seven to nine hours of sleep a night for optimal functionality. Read on to see just how much of an impact moderate sleep deprivation can have on your mind and body.By getting less than six hours of sleep a night, you could be putting yourself at risk of high blood pressure. When you sleep, your heart gets a break and is able to slow down for a significant period of time. But cutting back on sleep means your heart has to work overtime without its allotted break. In constantly doing so, your body must accommodate to its new conditions and elevate your overall daily blood pressure. And the heart isn’t the only organ that is overtaxed by a lack of sleeps. The less sleep you get, the less time the brain has to regulate stress hormones, and over time, sleep deprivation could permanently hinder the brain’s ability to regulate these hormones, leading to elevated blood pressure.We all hang around in bed during our bouts of illness. But did you know that skipping out on the bed rest can increase your risk of getting sick? Prolonged sleep deprivation has long been associated with diminished immune functions, but researchers have also found a direct correlation between “modest”sleep deprivation—less than six hours—and reduced immune response. So try to toughen up your immune system by getting at least seven hours of sleep a night, and maintaining a healthy diet. You’ll be glad you got that extra hour of sleep the next time that bug comes around and leaves everyone else bedridden with a fever for three days.During deep REM sleep, your muscles (except those in the eyes) are essentially immobilized in order to keep you from acting out on your dreams. Unfortunately, this effort your body makes to keep you safe while dreaming can sometimes backfire,resulting in sleep paralysis. Sleep paralysis occurs when the brain is aroused from its REM cycle, but the body remains in its immobilizing state. This can be quite a frightening sensation because, while your mind is slowly regaining consciousness, it has no control over your body, leaving some with a feeling of powerlessness, fear and panic. Most people experience this eerie phenomena at least once in their lives, but those who are sleep deprived are more likely to have panicked episodes of sleep paralysis that are usually accompanied by hallucinations, as well.For a second, imagine all of your memories are erased; every birthday, summer vacation, even what you did yesterday afternoon is completely lost, because you have no recollection of them.It’s a chilling thought, but that is what a life without sleep would be like. Sleep is essential to the cognitive functions of the brain, and without it, our ability to consolidate memories, learn daily tasks, and make decisions is impaired by a large degree. Research has revealed that REM sleep, or dream-sleep, helps solidify the “fragile”memories the brain creates throughout the day to that they can be easily organized and stored in the mind’s long-term cache.56. According to the passage, what is the meaning of “sleep deprivation”?A. To sleep for an average period of time.B. To sleep deeply without dreaming.C. To sleep less than needed.D. To sleep modestly.57. Which of the following statements is TRUE according to Paragraph 3?A. When everyone else gets a fever, those with sleep deprivation will be abele to sleep longer.B. When everyone else gets a fever, those who usually have adequate sleep will be alright.C. Only modest sleep deprivation could weaken the immune system.D. Prolonged sleep deprivation will not have impact on the immune system.58. Why is there the so-called “sleep paralysis”?A. It occurs when you are unable to wake up from dreams while you are sleeping.B. It occurs when you brain immobilizes your body in order to keep you from dreaming.C. Because you are usually too frightened to move your body when waking up from deep REM sleep.D. Because your body, immobilized when dreaming, may still be unable to move even when your brain is waking up.59.Which of the following statements is TRUE according to the last paragraph?A. Memories are part of the cognitive function of the brain.B. Memories created during the daytime are usually fragile and impaired.C. You are likely to lose your memories of yesterday after a night’s sleep.D. Long term memory cannot be formed without dream-sleep.60. What effects of sleep deprivation on human mind and body are discussed in this passage?A. High blood pressure, a toughened immune system, sleep paralysis, and memory loss.B. Blood pressure, immune system, sleep paralysis, and long term memory.C. Blood pressure, immune system, the brain and the body, and memory.D. High blood pressure, a weakened immune system, sleep paralysis, and memory loss.Part V: Proofreading (15%)Directions: In the following passage, there are altogether 15 mistakes, ONE in each numbered and underlined part.

Mark your answers on the Answer Sheet.2009 was the worst year for the record labels in a decade31 was 2008, and before that 2007 and 2006. In fact, industry revenues have been 32 for the past 10 years. Digital sales are growing, but not as fast as traditional sales are falling.Maybe that’s because illegal downloads are so easy. People have been 33 intellectual property for centuries, but it used to be a time-consuming way to generate markedly 34 copies. These days, high-quality copies are 35 . According to the Pew Internet project, people use file-sharing software more often than they do iTunes and other legal shops.I’d like to believe, as many of my friends seem to, that this practice won’t do much harm. But even as I’ve heard over the past decade that things weren’t 36 bad, that the music industry was moving to a new, better business model, each year’s numbers have been worse. Maybe it’s time to admit that we may never find a way to 37 consumers who want free entertainment with creators who want to get paid.38 on this problem, the computational neuroscientist Anders Sandberg recently noted that although we have strong instinctive feelings about ownership, intellectual property doesn’t always 39 that framework. The harm done by individual acts of piracy is too small and too abstract.“The nature of intellectual property,”he wrote, “makes it hard to maintain the social and empathic 40 that keep(s) us from taking each other’s things.”31.

For each question or unfinished statement, four answers are given. Read the passages carefully and choose the best answer to each question. Mark your choices on the Answer Sheet.Passage OneCancer has always been with us, but not always in the same way. Its care and management have differed over time, of course, but so, too, have its identity, visibility, and meanings. Pick up the thread of history at its most distant end and you have cancer the crab—so named either because of the ramifying venous processes spreading out from a tumor or because its pain is like the pinch of a crab’s claw. Premodern cancer is a lump, a swelling that sometimes breaks through the skin in ulcerations producing foul-smelling discharges. The ancient Egyptians knew about many tumors that had a bad outcome, and the Greeks made a distinction between benign tumors (oncos) and malignant ones (carcinos). In the second century A．D．, Galen reckoned that the cause was systemic, an excess of melancholy or black bile, one of the body’s four “humors,”brought on by bad diet and environmental circumstances. Ancient medical practitioners sometimes cut tumors out, but the prognosis was known to be grim. Describing tumors of the breast, an Egyptian papyrus from about 1600 B．C．concluded: “There is no treatment.”The experience of cancer has always been terrible, but, until modern times, its mark on the culture has been light. In the past, fear coagulated around other ways of dying: infectious and epidemic diseases (plague, smallpox, cholera, typhus, typhoid fever); “apoplexies”(what we now call strokes and heart attacks); and, most notably in the nineteenth century, “consumption”(tuberculosis). The agonizing manner of cancer death was dreaded, but that fear was not centrally situated in the public mind—as it now is. This is one reason that the medical historian Roy Porter wrote that cancer is “the modern disease par excellence,”and that Mukherjee calls it “the quintessential product of modernity.”At one time, it was thought that cancer was a “disease of civilization,” belonging to much the same causal domain as “neurasthenia” and diabetes, the former a nervous weakness belie ved to be brought about by the stress of modern life and the latter a condition produced by bad diet and indolence. In the eighteenth and nineteenth centuries, some physicians attributed cancer—notably of the breast and the ovaries—to psychological and behavioral causes. William Buchan’s wildly popular eighteenth-century text “Domestic Medicine”judged that cancers might be caused by “excessive fear, grief, religious melancholy.”In the nineteenth century, reference was repeatedly made to a “cancer personality,”and, in some versions, specifically to sexual repression. As Susan Sontag observed, cancer was considered shameful, not to be mentioned, even obscene. Among the Romantics and the Victorians, suffering and dying from tuberculosis might be considered a badge of refinement; cancer death was nothing of the sort. “It seems unimaginable,”Sontag wrote, “to aestheticize”cancer.41. According to the passage, the ancient Egyptians .A. called cancer the crabB. were able to distinguish benign tumors and malignant onesC. found out the cause of cancerD. knew about a lot of malignant tumors42. Which of the following statements about the cancers of the past is best supported by the passage?A. Ancient people did not live long enough to become prone to cancerB. In the past, people did not fear cancerC. Cancer death might be considered a badge of refinementD. Some physicians believed that one s own behavioral mode could lead to cancer43. Which of the following is the reason for cancer to be called “the modern disease”?A. Modern cancer care is very effectiveB. There is a lot more cancer nowC. People understand cancer in radically new ways nowD. There is a sharp increase in mortality in modern cancer world44.“Neurasthenia”and diabetes are mentioned because .A. they are as fatal as cancerB. they were considered to be “disease of civilization”C. people dread them very muchD.they are brought by the high pressure of modern life45. As suggested by the passage, with which of the following statements would the author most likely agree?A. The care and management of cancer have development over timeB. The cultural significance of cancer shifts in different timesC. Cancer s identity has never changedD. Cancer is the price paid for modern lifePassage TwoIf you happened to be watching NBC on the first Sunday morning in August last summer, you would have seen something curious. There, on the set of Meet the Press, the host, David Gregory, was interviewing a guest who made a forceful case that the U．S．economy had become “very distorted.”In the wake of the recession, this guest explained, high-income individuals, large banks, and major corporations had experienced a “significant recovery”; the rest of the economy, by contrast—including small businesses and “a very significant amount of the labor force”—was stuck and still struggling. What we were seeing, he argued, was not a single economy at all, but rather “fundamentally two separate types of economy,”increasingly distinct and divergent.This diagnosis, though alarming, was hardly unique: drawing attention to the divide between the wealthy and everyone else has long been standard fare on the left. (The idea of “two Americas”was a central theme of John Edwards’s 2004 and 2008 presidential runs.) What made the argument striking in this instance was that it was being offered by none other than the former five-term Federal Reserve Chairman Alan Greenspan: iconic libertarian, preeminent defender of the free market, and (at least until recently) the nation’s foremost devotee of Ayn Rand. When the high priest of capitalism himself is declaring the growth in economic inequality a national crisis, something has gone very, very wrong.This widening gap between the rich and non-rich has been evident for years. In a 2005 report to investors, for instance, three analysts at Citigroup advised that “the World is dividing into two blocs—the Plutonomy and the rest”.In a plutonomy there is no such animal as “the U．S．consumer”or “the UK consumer”, or indeed “the Russian consumer”. There are rich consumers, few in number, but disproportionate in the gigantic slice of income and consumption they take. There are the rest, the “non-rich”, the multitudinous many, but only accounting for surprisingly small bites of the national pie.Before the recession, it was relatively easy to ignore this concentration of wealth among an elite few. The wondrous inventions of the modern economy—Google, Amazon, the iPhone broadly improved the lives of middle-class consumers, even as they made a tiny subset of entrepreneurs hugely wealthy. And the less-wondrous inventions—particularly the explosion of subprime credit—helped mask the rise of income inequality for many of those whose earnings were stagnant.But the financial crisis and its long, dismal aftermath have changed all that. A multi-billion-dollar bailout and Wall Street’s swift, subsequent reinstatement of gargantuan bonuses have inspired a narrative of parasitic bankers and other elites rigging the game for their own benefit. And this, in turn, has led to wider-and not unreasonable-fears that we are living in not merely a plutonomy, but a plutocracy, in which the rich display outsize political influence, narrowly self interested motives, and a casual indifference to anyone outside their own rarefied economic bubble.46. According to the passage, the U．S．economy .A. fares quite wellB. has completely recovered from the economic recessionC. has its own problemsD. is lagging behind other industrial economies47. Which of the following statement about today’s super-elite would the passage support?A. Today’s plutocrats are the hereditary eliteB. Today’s super-rich are increasingly a nation unto themselvesC. They are the deserving winners of a tough economic competitionD. They are worried about the social and political consequences of rising income inequality48. What can be said of modern technological innovations?A. They have lifted many people into the middle class.B. They have narrowed the gap between the rich and the non-rich.C. They have led to a rise of income inequality.D. They have benefited the general public.49. The author seems to suggest that the financial crisis and its aftermath .A. have compromised the rich with the non-richB. have enriched the plutocratic eliteC. have put Americans on the alert for too much power the rich possessD. have enlarged the gap between the rich and non-rich50. The primary purpose of the passage is to .A. present the financial imbalance in the U．S．B. display sympathy for the working classC. criticize the super elite of the Unite StatesD. appreciate the merits of the super rich in the U．S．Passage ThreeCharles Darwin’s “On the Origin of Species”is credited with sparking evolution’s revolution in scientific thought, but many observers had pondered evolution before him. It was understanding the idea’s significance and selling it to the public that made Darwin great, according to the Arnold Arboretum’s new director.William Friedman, the Arnold Professor of Organism and Evolutionary Biology who took over as arboretum director Ja n．1, has studied Darwin’s writings as well as those of his predecessors and contemporaries. While Darwin is widely credited as the father of evolution, Friedman said the “historical sketch”that Darwin attached to later printings of his masterpiece was intended to mollify those who demanded credit for their own earlier ideas.The historical sketch grew with each subsequent printing, Friedman told an audience Monday (Ja n．10), until, by the 6th edition, 34 authors were mentioned in it. Scholars now believe that somewhere between 50 and 60 authors had beaten Darwin in their writings about evolution Included was Darwin’s grandfather, Erasmus Darwin, a physician who irritated clergymen with his insistence that life arose from lower forms, specifically mollusks.Friedman’s talk, “A Darwinian Look at Darwin’s Evolutionist Ancestors,”took place at the arboretum’s Hunnewell Building and was the first in a new Director’s Lecture Series.Though others had clearly pondered evolution before Darwin, he wasn’t without originality. Friedman said that Darwin’s thinking on natural selection as the mechanism of evolution was shared by few, most prominently Alfred Wallace, whose writing on the subject after years in the field spurred Darwin’s writing of “On the Origin of Species.”Although the book runs more than 400 pages, Friedman said it was never the book on evolution and natural selection that Darwin intended. In 1856, three years before the book was published, he began work on a detailed tome on natural selection that wouldn’t see publication until 1975.The seminal event in creating “On the Origin of Species”occurred in 1858, when Wallace wrote Darwin detailing Wallace’s ideas of evolution by natural selection. The arrival of Wallace’s ideas galvanized Darwin into writing “On the Origin of Species”as an “abstract”of the ideas he was painstakingly laying out in the larger work.This was a lucky break for Darwin, because it forced him to write his ideas in plain language, which led to a book that was not only revolutionary, despite those who’d tread similar ground before, but that was also very readable.Though others thought about evolution before Darwin, scientific discovery requires more than just an idea. In addition to the concept, discovery requires the understanding of the significance of the idea, something some of the earlier authors clearly did not have—such as the arborist who buried his thoughts on natural selection in the appendix of a book on naval timber. Lastly, scientific discovery demands the ability to convince others of the correctness of an idea. Darwin, through “On the Origin of Species,”was the only thinker of the time who had all three of those traits, Friedman said.“Darwin had the ability to convince others of the correctness of the idea,” Friedman said, adding that even Wallace, whose claim to new thinking on evolution and natural selection was stronger than all the others, paid homage to Darwin by titling his 1889 book on the subject, “Darwinism.”51. According to William Friedman, Darwin’s “On the Origin of Species”is great in that.A. it was the most studied by later scientistsB. it had significant ideas about evolutionC. it was the first to talk about evolutionD. it was well received by the public52. Friedman believes that Darwin attached a “historical sketch”to later printings of his book in an attempt to .A. credit the ideas about evolution before hisB. claim himself as the father of evolutionC. introduce his grandfather to the readerD. summarize his predecessors work53. In Friedman s view, Darwin s originality lies in .A. his thinking on natural selection as the mechanism of evolutionB. his sharing ideas about evolution with his contemporariesC. the way he wrote “On the Origin of Species”D. the way he lectured on the ideas of evolution54. We have learned that at first Darwin intended to write his idea in .A. a much larger bookB. a 400page bookC. scientific termsD. plain language55. Scientific discovery requires all the following Expect .A. coming up with a new ideaB. understanding the significance of the ideaC. making claims to the idea by writing booksD. convincing others of the correctness of the idesPassage FourMany adults may think they are getting enough shut-eye, but in a major sleep study almost 80 percent of respondents admitted to not getting their prescribed amount of nightly rest. So, what exactly is the right amount of sleep? Research shows that adults need an average of seven to nine hours of sleep a night for optimal functionality. Read on to see just how much of an impact moderate sleep deprivation can have on your mind and body.By getting less than six hours of sleep a night, you could be putting yourself at risk of high blood pressure. When you sleep, your heart gets a break and is able to slow down for a significant period of time. But cutting back on sleep means your heart has to work overtime without its allotted break. In constantly doing so, your body must accommodate to its new conditions and elevate your overall daily blood pressure. And the heart isn’t the only organ that is overtaxed by a lack of sleeps. The less sleep you get, the less time the brain has to regulate stress hormones, and over time, sleep deprivation could permanently hinder the brain’s ability to regulate these hormones, leading to elevated blood pressure.We all hang around in bed during our bouts of illness. But did you know that skipping out on the bed rest can increase your risk of getting sick? Prolonged sleep deprivation has long been associated with diminished immune functions, but researchers have also found a direct correlation between “modest”sleep deprivation—less than six hours—and reduced immune response. So try to toughen up your immune system by getting at least seven hours of sleep a night, and maintaining a healthy diet. You’ll be glad you got that extra hour of sleep the next time that bug comes around and leaves everyone else bedridden with a fever for three days.During deep REM sleep, your muscles (except those in the eyes) are essentially immobilized in order to keep you from acting out on your dreams. Unfortunately, this effort your body makes to keep you safe while dreaming can sometimes backfire,resulting in sleep paralysis. Sleep paralysis occurs when the brain is aroused from its REM cycle, but the body remains in its immobilizing state. This can be quite a frightening sensation because, while your mind is slowly regaining consciousness, it has no control over your body, leaving some with a feeling of powerlessness, fear and panic. Most people experience this eerie phenomena at least once in their lives, but those who are sleep deprived are more likely to have panicked episodes of sleep paralysis that are usually accompanied by hallucinations, as well.For a second, imagine all of your memories are erased; every birthday, summer vacation, even what you did yesterday afternoon is completely lost, because you have no recollection of them. It’s a chilling thought, but that is what a life without sleep would be like. Sleep is essential to the cognitive functions of the brain, and without it, our ability to consolidate memories, learn daily tasks, and make decisions is impaired by a large degree. Research has revealed that REM sleep, or dream-sleep, helps solidify the “fragile”memories the brain creates throughout the day to that they can be easily organized and stored in the mind’s long-term cache.56. According to the passage, what is the meaning of “sleep deprivation”?A. To sleep for an average period of time.B. To sleep deeply without dreaming.C. To sleep less than needed.D. To sleep modestly.57. Which of the following statements is TRUE according to Paragraph 3?A. When everyone else gets a fever, those with sleep deprivation will be abele to sleep longer.B. When everyone else gets a fever, those who usually have adequate sleep will be alright.C. Only modest sleep deprivation could weaken the immune system.D. Prolonged sleep deprivation will not have impact on the immune system.58. Why is there the so-called “sleep paralysis”?A. It occurs when you are unable to wake up from dreams while you are sleeping.B. It occurs when you brain immobilizes your body in order to keep you from dreaming.C. Because you are usually too frightened to move your body when waking up from deep REM sleep.D. Because your body, immobilized when dreaming, may still be unable to move even when your brain is waking up.59.Which of the following statements is TRUE according to the last paragraph?A. Memories are part of the cognitive function of the brain.B. Memories created during the daytime are usually fragile and impaired.C. You are likely to lose your memories of yesterday after a night’s sleep.D. Long term memory cannot be formed without dream-sleep.60. What effects of sleep deprivation on human mind and body are discussed in this passage?A. High blood pressure, a toughened immune system, sleep paralysis, and memory loss.B. Blood pressure, immune system, sleep paralysis, and long term memory.C. Blood pressure, immune system, the brain and the body, and memory.D. High blood pressure, a weakened immune system, sleep paralysis, and memory loss.Part V: Proofreading (15%)Directions: In the following passage, there are altogether 15 mistakes, ONE in each numbered and underlined part.

Direction: Each of the passages is followed by some questions. For each question four answers are given. Read the passages carefully and choose the best answerto each question. Put your choice in the ANSWER SHEET. （10%）Passage One（1）Gerald Feinberg, the Columbia University physicist, once went so far as to declare that “everything possible will eventually be accomplished.”Well, that of course left only the impossible as the one thing remaining for daring intellectual adventurers to whittle away at. Feinberg, for one, thought that “they’d succeed even there.”（2）It was a point worth considering. How many times in the past had certain things been said to be impossible, only to have it turn out shortly thereafter that the item in question had alreadybeen done or soon would be. What greater cliché was there in the history of science than the comic litany of false it-couldn’t-be-dones; the infamous case of Auguste Comte saying in 1844 that it would never be known what the stars were made of, followed in a few years by the spectroscope being applied to starlight to reveal the stars’chemical composition; or the case of Lord Rutherford, the man who discovered the structure of the atom, saying in 1933 that dreams of controlled nuclear fission were “moonshine.” And those weren’t even the worst examples. No, the huffiest of all it-couldn’t-be-done claims centered on the notion that human beings could actually fly, either at all, or across long distance, or to the moon, the stars, or wherever else.（3）There had been so many embarrassments of this type that about mid-century Arthur C. Clarke came out with a guideline for avoiding them, which he termed Clarke’s Law: “When a distinguished but elderly scientist states that something is possible, he is almost certainly right. When he states that something is impossible, he is very probably wrong.”（4）Still, one had to admit there were lots of things left that were really and truly impossible, even if it took some ingenuity in coming up with a proper list of examples. Such as: “A camel cannot pass through the eye of a needle.”（Well, unless of course it was a very large needle.）Or:“It is impossible for a door to be simultaneously open and closed.”（Well, unless of course it was a revolving door.）（5）Indeed, watertight examples of the really and truly impossible were so exceptionally hard to come by that paradigm cases turned out to be either trivial or absurd. “I know I will never play the piano like Vladimir Horowitz,” offered Milton Rothman, a physicist,“no matter how hard I try.”Or, from Scott Lankford, a mountaineer; “Everest on roller skates.”21. The false it-couldn’t-be-dones in science are comic because ______ .A. they are clichés, repeated too often by scientistsB. they are almost always proved to be wrong by later scientific researchC. they are mocked at by later generationsD. they provide material for good comedies22. Which of the following statements is TRUE?A. The author uses the case of a camel passing through the eye of a needle to prove his point that there are things impossible to accomplish.B. That a scientist cannot play the piano like one of the best pianists is not a proper illustration to prove that in science there are things impossible to accomplish.C. Scott Lankford challenges the idea that mountaineers can never climb the Everest on roller skates.D. People now laugh at their predecessors for denying the possibility of human flight.23. Through this passage, the author wants to ______.A. show us that scientists in the past years have made a lot of misjudgmentsB. praise those scientists who dared to challenge the impossibleC. emphasize the great potential of the scientific research made by human beingsD. analyze what is possible and what is impossible through scientific effortsPassage Two（1）Since the lineage of investigative journalism is most directly traceable to the progressive era of the early 1900’s, it is not surprising that the President of the United States at the time wasamong the first to articulate its political dimensions. Theodore Roosevelt called investigative reporters “muckrakers, ” after a character from John Bunyan’s Pilgrim’s Progress who humbly cleaned “the filth off the floor.” Despite the misgivings implied by the comparison, Roosevelt saw the muckrakers as “often indispensable to the well-being of society”.（2）There are in the body politic, economic and social, many and grave evils, and there is urgent necessity for the sternest war upon them. There should be relentless exposure of and attack upon every evil man, whether politician or businessman.（3）Roosevelt recognized the value-laden character of investigative journalism. He perceived correctly that investigative reporters are committed to unearthing wrongdoing. For these journalists, disclosures of morally outrageous conduct maximize the opportunity for the forces of “good” to recognize and do battle with the forces of “evil.”（4）So, the current folklore surrounding investigative reporting closely resembles the American ideal of popular democracy. Partly a product of its muckraking roots, this idealized perspective is also an outgrowth of the commonly perceived effects of exposés published in the early 1970’s. The most celebrated of these exposés were the news stories that linked top White House officials to Watergate crimes. These stories were widely held responsible for the public’s loss of confidence in the Nixon administration, ultimately forcing the President’s resignation.24. When the author talks about the political dimensions of the investigative journalism he refersto __________.A. John Bunyan’s Pilgrim’s Progress and one of its characters “Muckrakers”B. its function of cleaning the dirt off the floor in public placesC. its relentless exposures of political and social evilsD. its indispensable status to the well-being of society25. Roosevelt’s comparison of investigative reporters to“muckrakers”shows his view that thesereporters ______.A. were treated lowly in the societyB. reduced journalism to a humble jobC. should be praised highly for their contributions to the societyD. did unpleasant but necessary work26. By using the word “folklore”, the author suggests that ______.A. people tend to romanticize what is thought to be American popular democracyB. investigative journalism enhances democracy and freedomC. people often circulate the stories they read from investigative reportsD. investigative reports have difficulty in convincing people as truth27. The Watergate incident is mentioned to show ______.A. journalism has a tangible effect on politicsB. the Watergate incident is an abuse of the political powerC. journalism subverts legitimate political powerD. the victory of American freedom of speechPassage Three（1）Viewed from a star in some other corner of the galaxy, Earth would be a speck, a faint blue dot hidden in the blazing light of our sun. While our neighbors Venus and Mars would reflecta fairly even glow, Earth would put on a little show. Earth’s light would brighten and dim as it spins, because oceans, deserts, forests and clouds－which are all too small to be seen from such a distance－reflect varying amounts of sunlight. The variations, it turns out, are so strong and distinctive that surprising amount of information could be taken from a simple ebb and flow of light. Scientists at Princeton University and the Institute for Advanced Study conducted a detailed study of Earth’s reflections as a way for human scientists to learn about distant planets that may be like our own.（2）“If you looked at our solar system from far away, and you looked at the terrestrial planets—Mercury, Venus, Earth and Mars—one of the quickest ways to see that Earth is unique is by looking at the light curve,” said Ed Turner, professor of astrophysics and a co-author of the study. “Earth has by far the most complicated light curve,” The standard thinking in the field had been that most of the information about an Earth-like planet would come from spectral analysis, a static reading of the relative component of different colors within the light, rather than a reading of changes over time. Spectral analysis would reveal the presence of gases such as water vapor, carbon dioxide and oxygen, in the planet’s atmosphere. Looking at the change in light over time does not replace spectral analysis, but it could greatly increase the amount of information scientists could learn, said Turner. It may indicate, for example, the presence of weather, oceans, ice or even plant life.28. “Earth would put on a little show” means: as it spins, __________.A. Earth is a more active planet than Venus and MarsB. Earth reflects a brighter light curve than Venus and MarsC. Earth shows oceans, deserts, forests and clouds, while Venus and Mars don’tD. Earth reflects sunlight in an ebb-and-flow manner29. Spectral reading of the light reflected by an Earth-like planet _________.A. can tell us the components of that planet’s atmosphereB. can locate oceans and forests on that planetC. can show what the weather on that planet is likeD. is the quickest way to study its light curve30. Which of the following statements is TRUE?A. Scientists at the Princeton University want to find that distant planets are like our Earth.B. Among all the terrestrial planets Earth’s light curve is the most complicated.C. Spectral study of the light will see no development of itself because it is static.D. Spectral reading is used as a supplementary method to the study of the change in light over time.Ⅱ. Direction: Read the following passage carefully and then explain in your own English the exact meaning of the numbered and underlined parts. Put your answers in the ANSWER SHEET.（31）A couple of months ago, Singaporean officials unintentionally made cinematic history. They slapped an NC-17 rating on a film—which means children under 17 cannot see it—not because of sex or violence of profanity, but because of bad grammar. Despite its apparently naughty title, Talking Cock, the movie is actually an innocuous comedy comprising four skitsabout the lives of ordinary Singaporeans. The censors also banned a 15-second TV spot promoting the flick.（32）All this is because of what the authorities deemed “excessive use of Singlish.”（33）Given the tough crackdown, you would expect Singlish to be a harmful substance that might corrupt our youth, like heroin or pornography. But it’s one of Singapore’s best-loved quirks, used daily by everyone from cabbies to CEOs.（34）Singlish is simply Singaporean slang, whereby English follows Chinese grammar and is liberally sprinkled with words from the local Chinese, Malay and Indian dialects.I like to talk cock, and I like to speak Singlish. It’s inventive, witty and colorful.（35）Singlish is especially fashionable these days among the younger generation, in part because it gives uptight Singapore a chance to laugh—at itself. But the government is not amused. It doesn’t like Singlish because it thinks it is bad language and bad for Singapore’s image as a commercial and financial center.Part Three: Cloze TestDirection: Fill in each numbered blank in the following passage with ONE suitable word to complete the passage.

2014—2016年北京大学博士研究生入学考试考博英语试题及参考答案

2014—2016年北京大学博士研究生入学考试英语真题及参考答案高清版2014真题02年部分II. Reading Comprehension (25 points)Directions: There are five passages in this part. Each of the passages is followed by five questions or unfinished statements. For each of them there are four choices marked A, B, C and D. Choose the best one and mark your answer on the ANSWER SHEET with a single line through the center.1There is a new type of small advertisement becoming increasingly common in newspaper classified columns. It is sometimes placed among “situations vacant”, although it does not offer anyone a job; and sometimes it appears among “situations wanted”, although it is not placed by someone looking for a job either. What it does is to offer help in applying for a job. “Contact us before writing application”, or “Make use of our long experience in preparing your curriculum vitae, or job history”, is how it is usually expressed. The growth and apparent success of such a specialized service is , of course, a reflection on the current high levels of unemployment. It is also, an indication of growing importance of the curriculum vitae.(or job history), with the suggestion that it may now qualify as an art form in its own right.There was a time when job seekers simply wrote letters of application. “JustA. there is lack of jobs available for artistic peopleB. there are so many top-level jobs availableC. there are so many people out of workD. the job history is considered to be a work of art .18. In the past it was expected that first-job hunters would .A. write an initial letter giving their life historyB. pass some exams before applying for a jobC. have no qualifications other than being able to read and writeD. keep any detailed information until they obtained an interview19. Later, as one went on to apply more important jobs, one was advised to include in the letter.something that would attract attention to one’s applicationa personal opinion about the organization one was trying to join something that would offered that person reading ita lie that one could easily get with telling20. The job history has become such an important document because .A. there has been a decrease in the number of jobs advertisedB. there has been an increase in the number of “qualified” job huntersC. jobs are becoming much more complicated nowadaysD. the other processes of applying for jobs are more complicated2Pity those who aspire to put the initials PhD after their names. After 16 years of closely supervised education, prospective doctors of philosophyare left more or less alone to write the equivalent of a large book. Most social-science postgraduates have still not completed their theses by the time their grant runs out after three years. They must then get a job and finish in their spare time, which can often take a further three years. By then , most new doctors are sick to death of the narrowly defined subject which has blighted their holidays and ruined their evenings.The Economic and Social Research Council, which gives grants to postgraduate social scientists, wants to get better value for money by cutting short this agony. It would like to see faster completion rates: until recently, only about 25% of PhD candidates were finishing within four years. The ESRC’s response has been to stop PhD grants to all institutions where the proportion taking less than four years is below 10%; in the first year of this policy the national average shot up to 39%. The ESRC feels vindicated in its toughness, and will progressively raise the threshold to 40% in two years. Unless completion rates improve further, this would exclude 55 out of 73 universities and polytechnics-including Oxford University, the London School of Economics and the London Business School.Predictably, howls of protest have come from the universities, who view the blacklisting of whole institutions as arbitrary and negative. They point out that many of the best students go quickly into jobs where they can apply their research skills, but consequently take longer to finis their theses. Polytechnics with as few as two PhD candidates complain that they are penalized by random fluctuations in student performance. The colleges say there is no hard evidence to prove that faster completion rates result fromgreater efficiency rather than lower standards or less ambitious doctoral topics.The ESRC thinks it might not be a bad thing if PhD students were more modest in their aims. It would prefer to see more systematic teaching of research skills and fewer unrealistic expectations placed on young men and women who are undertaking their first piece of serious research. So in future its grants will be given only where it is convinced that students are being trained as researchers, rather than carrying out purely knowledge-based studies.The ESRC can not dictate the standard of thesis required by external examiners, or force departments to give graduates more teaching time. The most it can do is to try to persuade universities to change their ways. Recalcitrant professors should note that students want more research training and a less elaborate style of thesis, too.21. By time new doctors get a job and try to finish their theses in spare time, .A. most of them died of some sicknessB. their holidays and evenings have been ruined by their jobsC. most of them are completely tired of the narrowly defined subjectD. most of their grants run out22. Oxford University would be excluded out of those universities that receive PhD grants from ESRC, because the completion rate of its PhD students’ theses within four years is lower than.A. 25%B. 40%C. 39%D. 10%23. All the following statements are the arguments against ESRC’s policy except .A. all the institutions on the blacklist are arbitrary and negativeB. there is no hard evidence to prove that faster completion rates result from greater efficiency rather than lower standards or less ambitious doctoral topics.C. many of the best students go quickly into jobs where they can apply their research skills, but consequently take longer to finish their theses.D. some polytechnics are penalized by random fluctuations in student performance24. The ESRC would prefer .A. that the students were carrying out purely knowledge-based studies rather than being trained as researchers.B. to see higher standards of PhD students’ theses and more ambitious doctoral topicsC. more systematic teaching of research skills to fewer unrealistic expectations placed on inexperienced young PhD students.D. that PhD students were less modest in their aims25. what the ESRC can do is to .A. force departments to give graduates more teaching timeB. try to persuade universities to change their waysC. dictate the standard of thesis required by external examinersD. note that students want more research training and less elaborate styleof thesis3Influenza should not be dismissed as a trivial disease. It kills thousands of people every year at a very high cost to the economy, hits hardest the young and the elderly, and is most dangerous for people over the age of 65. influenza is mainly a seasonal illness of the winter months, though in tropical and subtropical areas of Asia and the Pacific it can occur all the year round.The damaging effects of influenza can be prevented by immunization, but constant changes of antigenic specificity of the virus necessitate a different composition of the vaccine from one year to another. The network of WHO Collaborating Centers for Influenza and national institutes carries out influenza surveillance activities to monitor the evaluation of influenza virus strains, and WHO hold an annual consultation at the end of February to recommend the composition of the vaccine for the forthcoming epidemiological season. These recommendations are published immediately in the Weekly epidemiological record.Vaccination each year against influenza is recommended for certain high-risk populations. In closed or semi-closed settings, maximum benefit from immunization is likely to be achieved when more than three-quarters of the population are vaccinated so that the benefit of “herd immunity” can be exploited. Special care should be taken of the following groups:--adults and children with chronic disorders of the pulmonary or cardiovascular systems requiring regular medical follow-up or who had beenhospitalized during the previous year, including children with asthma; --residents of nursing homes and other establishments for patients of any age with chronic medical conditions;--all people over the age of 65.Physicians, nurses, and other personal in primary and intensive care units, who are potentially capable of transmitting influenza to high risk persons, should be immunized; visiting nurses and volunteer workers providing home care to high-risk persons should also be included.26. This passage .A. concerns the damaging effects of influenzaB. mentions the steps of fighting against the harmful effects of influenzaC. emphasizes the worry expressed by all age groupsD. both A and B27. That a different component part of the vaccine is necessary is principally due to the variable change of .A. virusB. strainC. antigenD. immunization28. Which has been done by World Health Organization in combating the bad effects of influenza?A. supervising the assessment of influenza virus strains.B. Holding meetings twice a year to provide the latest data concerning the composition of the vaccines.C. Publishing the related information in a WHO almanac.D. Stressing the importance of preventing influenza for people living in tropical areas of Asia.29. According to the passage, high-risk persons exclude which of thefollowing kinds of people ?A. Children suffering from asthma.B. The elderly with chronic pulmonary diseases.C. Middle aged people with chronic heart diseases.D. Nurses taking special care of the sick.30. In which of the following publications would this passage most likely be printed?A. A surgery book.B. A psychology bookC. An epidemiology book.D. An obstetrics book4In science the meaning of the word “explain”suffers with civilization’s every step in search of reality. Science can not really explain electricity, magnetism, and gravitation; their effects can be measured and predicted, but of their nature no more is known to the modern scientist than to Thales who first speculated on the electrification of amber. Most contemporary physicists reject the notion that man can ever discover what these mysterious forces “really”are. Electricity, Bertrand Russell says, “is not a thing, like St. Paul’s Cathedral; it is a way in which things behave. When we have told how things behave when they are electrified, we have told all thee is to tell.”Until recently scientists would have disapproved of such an idea. Aristotle, for example, whose natural science dominated Western thought for two thousand years, believed that man could arrive at an understanding of reality by reasoning from self-evident principles. He felt, for example, that it is a self-evident principle that everything in the universe has itsproper place, hence one can conclude that objects fall to the ground because that is where they belong, and smoking goes up because that is where it belongs. The goal of Aristotelian science was to explain why things happen. Modern science was born when Galileo began trying to explain how things happen and thus originated the method of controlled experiment which now forms the basis of scientific investigation.31. The aim of controlled scientific experiments is .A. to explain why things happenB. to explain how things happenC. to describe self-evident principlesD. to support Aristotelian science32. what principles most influenced scientific thought for two thousand years?A. The speculations of ThalesB. The forces of electricity, magnetism, and gravityC. Aristotle’s natural scienceD. Galileo’s discoveries33. Bertrand Russell’s notion about electricity is .A. disapproved of by most modern scientistsB. in agreement with Aristotle’s theory of self-evident principlesC. in agreement with scientific investigation directed toward “how”things happenD. in agreement with scientific investigation directed toward “why ”things happen34. The passage says that until recently scientists disagreed with the idea .A. that there are mysterious forces in the universeB. that man can not discover what forces “really” areC. that there are self-evident principlesD. that we can discover why things behave as they do35. Which of the following is the topic most likely to be discussed right after the passage?A. The most recent definition of “explain”B. The relationship between science and religionC. The limitations of scienceD. Galileo and the birth of modern science. 5Some weeks ago, riding in a cab from Boston to Cambridge, my driver turned and asked me what I did for a living . “Teach English”, I said. “Is that so? ”The young man continued. “I was an English major”But then, instead of chatting idly about Joyce or dropping the subject altogether, this driver caught me short. “You guys,”he said, turning back so that his furry face pressed into the glass partition, “ought to be shot”I think he meant it . The guilty party in this present state of affairs is not really the academic discipline. It is not the fault of English and philosophy and biology that engineering and accounting and computer science afford students better job opportunities and increased flexibility in career choice. Literature and an understanding of, say, man’s evolutionary past are as important as ever. They simply are no longer perceived in today’s market as salable. That is a harsh economic fact. And it is not only true in the United States. Employment prospects for liberal arts graduates in Canada, for example, aresaid to be the worst since the 1930s.What to do? I think it would be shortsighted for colleges and universities to advise students against majoring in certain subjects that do not appear linked (at least directly) to careers. Where our energies should be directed instead is toward the development of educational programs that combine course sequences in the liberal arts with course in the viable professions. Double majors---one for enrichment, one for earning one’s bread---have never been promoted very seriously in our institutions of higher learning, mainly because liberal arts and professional-vocational faculties have long been suspicious or contemptuous of one another. Thus students have been directed to one path or the other, to the disadvantage of both students and faculty.A hopeful cue could be taken, it seems to me, from new attempts in the health profession(nursing and pharmacy, for example), where jobs are still plentiful, to give the humanities and social sciences a greater share of the curriculum. Why could not the traditional history major in the college of arts and sciences be pointed toward additional courses in the business school, or to engineering, or to physical therapy? This strategy requires a new commitment from both the institution and the student and demands a much harder look at the allocation of time and resources. But in an age of adversity, double majors are one way liberal arts students can more effectively prepare for the world outside.36. What is the chief purpose of double majors?A. To help graduates of history major become successful businessmen.B. To provide liberal arts graduates with a method of meeting effectively the challenge in employment.C. To extend their knowledge learnt in the college.D. To moderate the tension between liberal arts and vocational faculties.37. In paragraph 1, the sentence “You guys ought to be shot” shows that at heart the driver .A. felt greatly regretted about the major he had chosenB. felt a deep hatred for all the English teachers in his former collegeC. complained that his teachers hadn’t taught him how to survive in this competitive society.D. held a deep contempt in the author because of his scholastic manner38. It can be inferred from the passage that the blame for the present state of affairs lies in the fact that .A. the course sequences themselves are unreliable.B. more and more students start to select science majorsC. almost none of the specialties the students major in might be salable in today’s marketD. the opportunities of employment are scarce for graduates of non-science majors39. The obstacles in course sequences in academic schooling are indicated in all of the following EXCEPT .A. the misguidance of major-selection in some of the institutions of higher learningB. the current curriculum couldn’t keep up with the development of thesocietyC. the inharmonious relation among the teaching facultiesD. the authorities of higher learning attach only little importance to course sequences40. This passage can best be titled as .A. Harsh Economic FactB. Double Majors, a Way OutC. Careers, Schooling fro BetterD. Market for Graduates6Does an unborn baby know his mother’s voice? psychology professor Anthony DeCasper advised an ingenious experiment to find out. He placed padded earphones over a newborn’s ears and gave him a bottle nipple attached to a closed rubber tube. Changes in pressure in the tube switched channels on a tape recorder. If the baby paused extra long between bursts of sucking, he heard on channel; if he paused shorter than average, he heard the other. The baby now had the ability, in effect to change channels.DeCasper found that newborns choose the recording of their mother’s voice over that of another woman’s. The baby, however, has no innate interest in his father’s voice, which is heard in the womb only from time to time, while the mother’s voice is ever present. Within two weeks after birth, however, the baby can recognize Dad’s voice too.A newborn is even attuned to the cadence and rhythm of his native language. In a French study using a setup similar to DeCasper’s, French babies given the choice between French and Russian words responded more to the sound of French.Brian Satt, a research specialist in clinical psychology, has parents sing a lullaby-like “womb song”to their babies. The unborn baby often develops a specific, consistent movement pattern when its song is sung. According to Satt, most parents can calm a fussy newborn with the song most of the time, which is a prize worth more than rubies to a new parent.He is roused by a heavy jolt. His mother has tripped and fallen heavily on one hip. He is much too well cushioned to experience any injury, but her pain and the fear that she may have hurt him floods both their bodies with adrenaline and other stress-related hormones. He cries and kicks vigorously, a cry never heard because there is no air to make sound. As she recovers the stress hormones ebb away, and he calms down too.41. Which of the following is NOT mentioned about the unborn baby in the passage?A. An unborn baby can occasionally hear his father’s voice.B. Dc. Casper’s approach proved absolutely effective in a French experiment.C. An unborn baby is able to identify the tone and rhythm of his native language.D. Parents are able to soothe a fussy newly-born baby.42. According to the author, an unborn baby .A. is unable to identify his mother’s lullaby after birthB. is able to identify his mother’s voice rather than that of others’C. is able to help release adrenaline and other stress-related hormonesD. is able to distinguish French accent from Russian accent43. It is known from the passage that .A. mother’s stress, anger, shock or grief might not hurt the unborn baby in the wombB. an unborn baby’s cry might never be heard because of the particular condition of the womb.C. lullabies are the most precious means to young parentsD. an unborn baby has to move at intervals in the womb44. The author believes that the reaction of an unborn baby to his mother’s voice .A. belongs to one of the natural tendenciesB. is an indication which shows an unborn baby can use all his senses after birthC. is but a physiological circulation of any human beingD. is the most important factor which leads an unborn baby to the survival in the womb45. It can be assumed that the paragraph preceding the passage most probably discussed .A. the development of the baby in his mother’ s wombB. the well-developed taste buds of the babyC. the fact that the baby remains motionless just as what he performs in the first month of his mother’s pregnancyD. the fact that the baby can start to use some of his senses by the last few weeks of pregnancyⅢ. Translation and Writing (55 points)Part A TranslationTranslate the following into Chinese (30 points):Engineering is the professional art of applying science to the optimum conversion of the resources of nature to the uses of humankind. Engineering has been defined as the creative application of “scientific principles to design or develop structures, machines, apparatus, or manufacturing processes, or works utilizing them singly or in combination.” The term engineering is sometimes more loosely defined, especially in Great Britain, as the manufacture or assembly of engines, machine tools, and machine parts. Associated with engineering is a great body of special knowledge; preparation for professional practice involves extensive training in the application of that knowledge. The function of the scientist is to know, while that of the engineer is to do. The scientist adds to the store of verified, systematized knowledge of the physical world; the engineer brings this knowledge to bear on practical problems. Engineering is based principally on physics, chemistry, and mathematics and their extensions into materials science, solid and fluid mechanics, thermodynamics, and systems analysis.2Although for the purpose of this article English literature is treated as being confined to writings in English by natives or inhabitants of the British Isles, it is to a certain extent the case that literature---and this is particularly true of the literature written in English---knows nofrontiers. Thus, English literature can be regarded as a cultural whole of which the mainstream literatures of the United States, Australia, New Zealand, and Canada and important elements in the literatures of other commonwealth countries are parts. It can be argued that no single English novel attains the universality of the Russian writer Leo Tolstoy’s War and Peace. Yet in the Middle ages the Old English literature was influenced and gradually changed by the Latin and French writings, eminently foreign in origin in which the churchmen and the Norman conquerors expressed themselves. From this combination emerged a flexible and subtle linguistic instrument exploited by Geoffrey Chaucer and brought to supreme application by William Shakespeare.Translate the following into English (10 points):从二十世纪中叶起，名国政府对科学技术的重视引起了各级教育机构的响应，理论科学和应用科学的巨大进步也激起了人们学习自然科学的兴趣，科学技术因此有了飞速的发展。

北京大学考博英语模拟试题精解

北京大学考博英语模拟试题精解47.[精解]本题考核的知识点是：被动语态、定语从句的译法。

该句的句子主干是：the mass...had always been associated with an indestructible material substance，其中完成时的被动语态had been associated with，可译成“总是与...相关联”。

with some“stuff”of which引导的定语从句修饰indestructible material substance，翻译的时候应该按照汉语习惯，将定语前置，放到所修饰的名词前面。

可直译为“所有物质被认为是由这种物质构成的”，或意译为“这是构成一切物质的东西”。

考生应该注意of与be made是词组be made of被分隔了的形式，译成“由...构成的”。

词汇：classical“经典的，古典的”，在该句中取其第二种含义，译成“古典物理”。

48.[精解]本题考核知识点：同位语、宾语从句、定语从句、现在分词作定语的译法。

该句的句子主干是The fact means that...，fact后是that引导的同位语从句，同位语从句的翻译和定语从句翻译有很多相似之处，如果句子较长，可单独成句，并用“这一事实...”将从句和主语连接在一起，that可以省略不译。

Means后是that引导的宾语从句，其中有两个并列的谓语：can no longer be seen as和has to be conceived as，译为“不能再被看成...，而应该被看成...”。

a process是宾语补足语a dynamic pattern 的同位语，可以译成并列结构。

Involving...部分是现在分词作定语，修饰a process，按照汉语习惯译成“与……有关的过程”。

Which...mass是定语从句，修饰the energy，可译成“表现为粒子质量的能量。

WritingStructure and V ocabulary1．“What courses are you going to do next semester?” I don’t know. But it’s about time______on something.A．I’d decideB．I decidedC．I decideD．I’m deciding正确答案：B解析：此题考查的是句型It is about time that的使用方法，这是一个虚拟语气句型，表示与现在的事实相反，因而that从句的谓语动词一般用一般过去时。

如：It is about time that we went to school(现在是我们该去上学的时候了)。

本题的句意是“你下学期要选什么课?”“我不知道，但是应该是做决定的时候了”。

句首处省略了主语，所以应该用现在分词的完成式。

如：Having succeeded in the last examination，she was more confident of another success in the coming one(因为成功地通过了上次的考试，因此她更有信心在即将到来的考试中再次取得成功)。

2.不用will/shall表达将来时的形式：
(1)be going to表示现在的打算和意图;
(2)arrive,come,drive,go,leave,retire,return,set off,start, take off等表示移位的动词的进行体表示按计划肯定要发生的将来动作;
(3)be to(do)表示安排、计划、决定、命令或注定要发生的事，如：
Greater efforts to increase agricultural production must be made if food shortage is to be avoided.
(4)be about to(do)表示将要(做)，如：

(画线部分一般不用will be)
(7)在时间、条件、让步从句中，一般现在时代替将来时，但要注意区别从句的类型，如：
I don’t know where he will go tomorrow.我不知道他明天去哪儿。

(宾语从句)
I’ll tell him when you will ring again.我告诉他你什么时候再来电话。

(宾语从句)
比较：I’ll tell him when you ring again.你再打电话时我告诉他。

(状语从句)
(8)在make sure,make certain,see(to it)后的that从句中，谓语动词用一般现在时代替将来时，如：
See to it that you include in the paper whatever questions they didn’t know the answer to last time.
(include不能用will include或其他形式)
3.完成时是时态测试的重点，注意与完成时连用的句型和时间状语：
(1)by/between/up to/till+过去时间、since、by the time/when+表示过去发生情况的从句，主句用过去完成时。

如：
We had just had our breakfast when an old man came to the door.

(5)在no sooner…than…,hardly/scarcely…when/before…句型中，主句常用过去完成时。

(6)其他与完成时连用的时间状语：all this while,all this year,for some time,so far,already,before,just,long,yet等。

4.完成进行时指动作在完成时的基础上还要继续下去。

如：
The company has been promising a rise in salary for ages,but nothing has happened.
The school board listened quietly as John read the demand that his followers had been demonstrating for.
时态、语态答题思路：
(1)先根据选项的区别点确定考题要点为时态，然后回到题句中寻找给出的或暗示的时间状语，缩小选择范围，进而选出正确答案;
(2)根据谓语动词与句子主语或非谓语动词与其逻辑主语的关系，确定句子是主动语态还是被动语态。
