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。

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.

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.

(68) They will send a text message or e-mail alerting them when the order is ready, which usually takes about four hours.(69) “Not only we see it as a nice convenience for customers, but we also saw it as a way to drive incremental traffic to the stores, and incremental sales,”said Steve Nave, senior vice president and general manager of Walmar t．Com.(70) The program will include about 40000 items likewise electronics, toys, home décor and sporting goods. (71) As of now, it does not include groceries, though M r．Nave did dismiss that possibility.(72) “We’re not ready to talk today about everything that’s going on in grocery,”he said“What we’ve tried to do is (73) focus on those categories where customers are most likely to be willing to make the purchase after they touch it or look at it.(74) This is a convenient play, trying to figure out what are the things that are going to drive more customers into the stores.”Wal-Mart also announced that (75) it was shortened the time customers would have to wait for ship-to-store items, to four to seven days, from seven to 10 days.Part VI: Writing (15%)。

２０１５考博英语定语从句和同位语从句详解定语从句定语从句是英语学习的难点，也是考博英语考查的重点。

掌握考博英语的定语从句从以下维度的内容进行学习：一、定义定语从句是指在句中做定语作用，修饰句中的名词或代词的从句，其中被修饰的名词或代词为先行词。

当关系代词作定语从句的主语时，其后的谓语动词的人称和数取决于先行词的人称和数。

二、定语从句的结构定语从句一般位于先行词的后面，定语从句由关系代词who,whom,whose,that,which，that,as和关系副词when,where,why等引导。

(一)关系代词引导的定语从句关系代词所代替的先行词是人或物的名词或代词，并在句中充当主语、宾语、定语等成分。

关系代词在定语从句中做主语时，从句谓语动词的人称和数要和先行词保持一致。

(1)who,whom,that这些词代替的先行词是人的名词或代词，在从句中做主语和宾语。

例如：·Is he the man who/thatwants to see you?他就是你想见的人吗?(who/that在从句中作主语)·He is the man whom/that I saw yesterday。

他就是我昨天见的那个人。

(whom/that在从句中作宾语)(2)whose用作关系词表示所属格，也可看作是关系形容词，因为它后面必须接一个名词连用。

不能单独使用。

例如：·They rushed overto help the man whose car had broken down。

那人车坏了，大家都跑过去帮忙。

(3)which,that所代替的先行词是事物的名词或代词，在从句中可做主语、宾语等。

作宾语时常可省略。

例如：·Aprosperity which/that had never been seen before appears in thecountryside。
