Mark your answers on ANSWER SHEET 1.(40 points)Text1The longest bull run in a century of art-market history ended on a dramatic note with a sale of 56 works by Damien Hirst, “Beautiful Inside My Head Forever”, at Sotheby’s in London on September 15th 2008 (see picture). All but two pieces sold, fetching m ore than ā70m, a record for a sale by a single artist. It was a last hurrah. As the auctioneer called out bids, in New York one of the oldest banks on Wall Street, Lehman Brothers, filed for bankruptcy.The world art market had already been losing momentum for a while after rising vertiginously since 2003. At its peak in 2007 it was worth some $65 billion, reckons Clare McAndrew, founder of Arts Economics, a research firm—double the figure five years earlier. Since then it may have come down to $50 billion. But the market generates interest far beyond its size because it brings together great wealth, enormous egos, greed, passion and controversy in a way matched by few other industries. MBA加油站In the weeks and months that followed Mr Hirst’s sale, spending of any sort became deeply unfashionable, especially in New York, where the bail-out of the banks coincided with the loss of thousands of jobs and the financial demise of many art-buying investors. In the art world that meant collectors stayed away from galleries and salerooms. Sales of contemporary art fell by two-thirds, and in the most overheated sector—for Chinese contemporary art—they were down by nearly 90% in the year to November 2008. Within weeks the world’s two biggest auction houses, Sotheby’s and Christie’s, had to pay out nearly $200m in guarantees to clients who had placed works for sale with them.MBA加油站编辑The current downturn in the art market is the worst since the Japanese stopped buying Impressionists at the end of 1989, a move that started the most serious contraction in the market since the second world war. This time experts reckon that prices are about 40% down on their peak on average, though some have been far more volatile. But Edward Dolman, Christie’s chief executive, says: “I’m pretty confident we’re at the bottom.”What makes this slump different from the last, he says, is that there are still buyers in the market, whereas in the early 1990s, when interest rates were high, there was no demand even though many collectors wanted to sell. Christie’s revenues in the first half of 2009 were still higher than in the first half of 2006. Almost everyone who was interviewed for this special report said that the biggest problem at the moment is not alack of demand but a lack of good work to sell. The three Ds—death, debt and divorce—still deliver works of art to the market. But anyone who does not have to sell is keeping away, waiting for confidence to return.21.In the first paragraph,Damien Hirst's sale was referred to as “a last victory”because ____-.A.the art market hadwitnessed a succession of victoryiesB.the auctioneer finally got the two pieces at the highest bidsC.Beautiful Inside My Head Forever won over all masterpiecesD.it was successfully made just before the world financial crisis22.By saying “spending of any sort became deeply unfashionable”(Line 1-2,Para.3),the author suggests that_____ .MBA加油站编辑A . collectors were no longer actively involved in art-market auctionsB .people stopped every kind of spending and stayed away from galleriesC.art collection as a fashion had lost its appeal to a great extentD .works of art in general had gone out of fashion so they were not worth buying23.Which of the following statements is NOT ture?A .Sales of contemporary art fell dramatically from 2007to 2008.B.The art market surpassed many other industries in momentum.C.The market generally went downward in various ways.D.Some art dealers were awaiting better chances to come.24.The three Ds mentioned in the last paragraph are ____A.auction houses ' favoritesB.contemporary trendsMBA加油站编辑C.factors promoting artwork circulationD.styles representing impressionists25.The most appropriate title for this text could be ___A.Fluctuation of Art PricesB.Up-to-date Art AuctionsC.Art Market in DeclineD.Shifted Interest in ArtsText2MBA加油站编辑I was addressing a small gathering in a suburban Virginia living room -- a women's group that had invited men to join them. Throughout the evening one man had been particularly talkative frequently offering ideas and anecdotes while his wife sat silently beside him on the couch. Toward the end of the evening I commented that women frequently complain that their husbands don't talk to them. This man quickly concurred. He gestured toward his wife and said "She's the talker in our family." The room burst into laughter; the man looked puzzled and hurt. "It's true" he explained. "When I come home from work I have nothing to say. If she didn't keep the conversation going we'd spend the whole evening in silence."This episode crystallizes the irony that although American men tend to talk more than women in public situations they often talk less at home. And this pattern is wreaking havoc with marriage.The pattern was observed by political scientist Andrew Hacker in the late '70s. Sociologist Catherine Kohler Riessman reports in her new book "Divorce Talk" that most of the women she interviewed -- but only a few of the men -- gave lack of communication as the reason for their divorces. Given the current divorce rate of nearly 50 percent that amounts to millions of cases in the United States every year -- a virtual epidemic of failed conversation.In my own research complaints from women about their husbands most often focused not on tangible inequities such as having given up the chance for a career to accompany a husband to his or doing far more than their share of daily life-support work like cleaning cooking social arrangements and errands. Instead they focused on communication: "He doesn't listen to me" "He doesn't talk to me." I found as Hackerobserved years before that most wives want their husbands to be first and foremost conversational partners but few husbands share this expectation of their wives.In short the image that best represents the current crisis is the stereotypical cartoon scene of a man sitting at the breakfast table with a newspaper held up in front of his face while a woman glares at the back of it wanting to talk.26.What is most wives' main expectation of their husbands?A.Talking to them.B.Trusting them.C.Supporting their careers.D. Shsring housework.27.Judging from the context ,the phrase “wreaking havoc”(Line 3,Para.2)most probably means ___ .A generating motivation.B.exerting influenceC.causing damageDcreating pressure28.All of the following are true EXCEPT_______A.men tend to talk more in public tan womenB.nearly 50percent of recent divorces are caused by failed conversationC.women attach much importance to communication between couplesDa female tends to be more talkative at home than her spouse29.Which of the following can best summarize the mian idea of this text ?A.The moral decaying deserves more research by sociologists .B.Marriage break_up stems from sex inequalities.C.Husband and wofe have different expectations from their marriage.D.Conversational patterns between man and wife are different.30.In the following part immediately after this text,the author will most probably focus on ______A.a vivid account of the new book Divorce TalkB.a detailed description of the stereotypical cartoonC.other possible reasons for a high divorce rate in the U.S.D a brief introduction to the political scientist Andrew HackerTxet3over the past decade, many companies had perfected the art of creating automatic behaviors —habits —among consumers. These habits have helped companies earn billions of dollars when customers eat snacks, apply lotions and wipe counters almost without thinking, often in response to a carefully designed set of daily cues.“There are fundamental public health problems, like hand washing with soap, that remain killers only because we can’t figure out how to change people’s habits,”Dr. Curtis said. “We wanted to learn from private industry how to create new behaviors that h appen automatically.”The companies that Dr. Curtis turned to —Procter & Gamble, Colgate-Palmolive and Unilever —had invested hundreds of millions of dollars finding the subtle cues in consumers’lives that corporations could use to introduce new routines.If you look hard enough, you’ll find that many of the products we use every day —chewing gums, skin moisturizers, disinfecting wipes, air fresheners, water purifiers, health snacks, antiperspirants, colognes, teeth whiteners, fabric softeners, vitamins —are results of manufactured habits. A century ago, few people regularly brushed their teeth multiple times a day. Today, because of canny advertising and public health campaigns, many Americans habitually give their pearly whites a cavity-preventing scrub twice a day, often with Colgate, Crest or one of the other brands.A few decades ago, many people didn’t drink water outside of a meal. Then beverage companies started bottling the production of far-off springs,and now office workers unthinkingly sip bottled water all day long. Chewing gum, once bought primarily by adolescent boys, is now featured in commercials as a breath freshener and teeth cleanser for use after a meal. Skin moisturizers are advertised as part of morningbeauty rituals,slipped in between hair brushing and putting on makeup.“Our products succeed when they become part of daily or weekly patterns,”said Carol Berning, a consumer psychologist who recently retired from Procter & Gamble, the company that sold $76 billion of Tide, Crest and other products last year. “Creating positive habits is a huge part of improv ing our consumers’ lives, and it’s essential to making new products commercially viable.”Through experiments and observation, social scientists like Dr. Berning have learned that there is power in tying certain behaviors to habitual cues through relentless advertising.

The jury is also said to be the best surviving example of direct rather than representative democracy. In a direct democracy, citizens take turns governing themselves, rather than electing representatives to govern for them.But as recently as in 1986, jury selection procedures conflicted with these democratic ideals. In some states, for example, jury duty was limited to persons of supposedly superior intelligence, education, and moral character. Although the Supreme Court of the United States had prohibited intentional racial discrimination in jury selection as early as the 1880 case of strauder v. West Virginia,the practice of selecting so-called elite or blue-ribbon juries provided a convenient way around this and other antidiscrimination laws.The system also failed to regularly include women on juries until the mid-20th century. Although women first served on state juries in Utah in 1898,it was not until the 1940s that a majority of states made women eligible for jury duty. Even then several states automatically exempted women from jury duty unless they personlly asked to have their names included on the jury list. This practice was justified by the claim that women were needed at home, and it kept juries unrepresentative of women through the 1960s.In 1968, the Congress of the United States passed the Jury Selection and Service Act, ushering in a new era of democratic reforms for the jury.This law abolished special educational requirements for federal jurors and required them to be selected at random from a cross section of the entire community. In the landmark 1975 decision Taylor v. Louisiana, the Supreme Court extended the requirement that juries be representative of all parts of the community to the state level. The Taylor decision also declared sex discrimination in jury selection to be unconstitutional and ordered states to use the same procedures for selecting male and female jurors.36.From the principles of theUS jury system,welearn that ______[A]both litcrate and illiterate people can serve on juries[B]defendants are immune from trial by their peers[C]no age limit should be imposed for jury service[D]judgment should consider the opinion of the public37.The practice of selecting so—called elite jurors prior to 1968 showed_____[A]the inadcquavy of antidiscrimination laws[B]the prevalent discrimination against certain races[C]the conflicting ideals in jury selection procedures38.Even in the 1960s,women were seldom on the jury list in some states because_____[A]they were automatically banned by state laws[B]they fell far short of the required qualifications[C]they were supposed to perform domestic duties[D]they tended to evade public engagement39.After the Jury Selection and Service Act was passed.___[A]sex discrimination in jury selection was unconstitutional and had to be abolished[B]educational requirements became less rigid in the selection of federal jurors[C]jurors at the state level ought to be representative of the entire community[D]states ought to conform to the federal court in reforming the jury system40.in discussing the US jury system,the text centers on_______[A]its nature and problems[B]its characteristics and tradition[C]its problems and their solutions[D]its tradition and developmentSection ⅢTranslation46.Directions:In this section there is a text in English .Translate it into Chinese.

Having endured apainful period of unsustainability in his own life made itclear to him that sustainability-oriented values must be expressed though everyday action and choice.Ning recalls spending aconfusing year in the late 1990s selling insurance. He’d been though the dot-com boom and burst and,desperate for ajob,signed on with a Boulder agency.It didin’t go well. “It was a really had move because that’s not my passion,”says Ning, whose dilemma about the job translated, predictably, into a lack of sales. “I was miserable, I had so much anxiety that I would wake up in the middle of the nightand stare at the ceiling. I had no money and needed the job. Everyone said, ‘Just wait, you’ll trun the corner, give it some time.’”翻译参考“坚持不懈”如今已成一个流行词汇，但对TedNing而言，这个概念一直有个人含义，经历了一段痛苦松懈的个人生活，使他清楚面向以坚持不懈为导向的价值观，必须贯彻到每天的行动和选择中。

All but two pieces sold, fetching more than ā70m, a record for a sale by a single artist. It was a last hurrah. As the auctioneer called out bids, in New York one of the oldest banks on Wall Street, Lehman Brothers, filed for bankruptcy.The world art market had already been losing momentum for a while after rising vertiginously since 2003. At its peak in 2007 it was worth some $65 billion, reckons Clare McAndrew, founder of Arts Economics, a research firm—double the figure five years earlier. Since then it may have come down to $50 billion. But the market generates interest far beyond its size because it brings together great wealth, enormous egos, greed, passion and controversy in a way matched by few other industries.In the weeks and months that followed Mr Hirst‟s sale, spending of any sort became deeply unfashionable, especially in New York, where the bail-out of the banks coincided with the loss of thousands of jobs and the financial demise of many art-buying investors. In the art world that meant collectors stayed away from galleries and salerooms. Sales of contemporary art fell by two-thirds, and in the most overheated sector—for Chinese contemporary art—they were down by nearly 90% in the year to November 2008. Within weeks the world‟s two biggest auction houses, Sotheby‟s and Christie‟s, had to pay out ne arly $200m in guarantees to clients who had placed works for sale with them.The current downturn in the art market is the worst since the Japanese stopped buying Impressionists at the end of 1989, a move that started the most serious contraction in the market since the second world war. This time experts reckon that prices are about 40% down on their peak on average, though some have been far more volatile. But Edward Dolman, Christie‟s chief executive, says: “I‟m pretty confident we‟re at the bottom.”What makes this slump different from the last, he says, is that there are still buyers in the market, whereas in the early 1990s, when interest rates were high, there was no demand even though many collectors wanted to sell. Christie‟s reven ues in the first half of 2009 were still higher than in the first half of 2006. Almost everyone who was interviewed for this special report said that the biggest problem at the moment is not a lack of demand but a lack of good work to sell. The three Ds—death, debt and divorce—still deliver works of art to the market. But anyone who does not have to sell is keeping away, waiting for confidence to return.21.In the first paragraph,Damien Hirst's sale was referred to as “a last victory”because ____-.A.the art market hadwitnessed a succession of victoryiesB.the auctioneer finally got the two pieces at the highest bidsC.Beautiful Inside My Head Forever won over all masterpiecesD.it was successfully made just before the world financial crisis22.By saying “spending of any sort became deeply unfashionable”(Line 1-2,Para.3),the author suggests that_____ .A . collectors were no longer actively involved in art-market auctionsB .people stopped every kind of spending and stayed away from galleriesC.art collection as a fashion had lost its appeal to a great extentD .works of art in general had gone out of fashion so they were not worth buying23.Which of the following statements is NOT ture?A .Sales of contemporary art fell dramatically from 2007to 2008.B.The art market surpassed many other industries in momentum.C.The market generally went downward in various ways.D.Some art dealers were awaiting better chances to come.24.The three Ds mentioned in the last paragraph are ____A.auction houses ' favoritesB.contemporary trendsC.factors promoting artwork circulationD.styles representing impressionists25.The most appropriate title for this text could be ___A.Fluctuation of Art PricesB.Up-to-date Art AuctionsC.Art Market in DeclineD.Shifted Interest in ArtsText2I was addressing a small gathering in a suburban Virginia living room -- a women's group that had invited men to join them. Throughout the evening one man had been particularly talkative frequently offering ideas and anecdotes while his wife sat silently beside him on the couch. Toward the end of the evening I commented that women frequently complain that their husbands don't talk to them. This man quickly concurred. He gestured toward his wife and said "She's the talker in our family." The room burst into laughter; the man looked puzzled and hurt. "It's true" he explained. "When I come home from work I have nothing to say. If she didn't keep the conversation going we'd spend the whole evening in silence."This episode crystallizes the irony that although American men tend to talk more than women in public situations they often talk less at home. And this pattern is wreaking havoc with marriage.The pattern was observed by political scientist Andrew Hacker in the late '70s. Sociologist Catherine Kohler Riessman reports in her new book "Divorce Talk" that most of the women she interviewed -- but only a few of the men -- gave lack of communication as the reason for their divorces. Given the current divorce rate of nearly 50 percent that amounts to millions of cases in the United States every year -- a virtual epidemic of failed conversation.In my own research complaints from women about their husbands most often focused not on tangible inequities such as having given up the chance for a career to accompany a husband to his or doing far more than their share of daily life-support work like cleaning cooking social arrangements and errands. Instead they focused on communication: "He doesn't listen to me" "He doesn't talk to me." I found as Hacker observed years before that most wives want their husbands to be first and foremost conversational partners but few husbands share this expectation of their wives.In short the image that best represents the current crisis is the stereotypical cartoon scene of a man sitting at the breakfast table with a newspaper held up in front of his face while a woman glares at the back of it wanting to talk.26.What is most wives' main expectation of their husbands?A.Talking to them.B.Trusting them.C.Supporting their careers.D. Shsring housework.27.Judging from the context ,the phrase “wreaking havoc”(Line 3,Para.2)most probably means ___ .A generating motivation.B.exerting influenceC.causing damageDcreating pressure28.All of the following are true EXCEPT_______A.men tend to talk more in public tan womenB.nearly 50percent of recent divorces are caused by failed conversationC.women attach much importance to communication between couplesDa female tends to be more talkative at home than her spouse29.Which of the following can best summarize the mian idea of this text ?A.The moral decaying deserves more research by sociologists .B.Marriage break_up stems from sex inequalities.C.Husband and wofe have different expectations from their marriage.D.Conversational patterns between man and wife are different.30.In the following part immediately after this text,the author will most probably focus on ______A.a vivid account of the new book Divorce TalkB.a detailed description of the stereotypical cartoonC.other possible reasons for a high divorce rate in the U.S.D a brief introduction to the political scientist Andrew HackerTxet3over the past decade, many companies had perfected the art of creating automatic behaviors —habits —among consumers. These habits have helped companies earn billions of dollars when customers eat snacks, apply lotions and wipe counters almost without thinking, often in response to a carefully designed set of daily cues.“There are fundamental public health problems, like hand washing with soap, that remain killers only because we can‟t figure out how to change people‟s habits,” Dr. Curtis said. “We wanted to learn from private industry how to create new behaviors that happen automatically.”The companies that Dr. Curtis turned to —Procter & Gamble, Colgate-Palmolive and Unilever —had invested hundreds of millions of dollars finding the subtle cues in consumers‟ lives that corporations could use to introduce new routines.If you look hard enough, you‟ll find that many of the products we use every day — chewing gums, skin moisturizers, disinfecting wipes, air fresheners, water purifiers, health snacks, antiperspirants, colognes, teeth whiteners, fabric softeners, vitamins —are results of manufactured habits. A century ago, few people regularly brushed their teeth multiple times a day. Today, because of canny advertising and public health campaigns, many Americans habitually give their pearly whites a cavity-preventing scrub twice a day, often with Colgate, Crest or one of the other brands.A few decades ago, many people didn‟t drink water outside of a meal. Then beverage companies started bottling the production of far-off springs,and now office workers unthinkingly sip bottled water all day long. Chewing gum, once bought primarily by adolescent boys, is now featured in commercials as a breath freshener and teeth cleanser for use after a meal. Skin moisturizers are advertised as part of morning beauty rituals,slipped in between hair brushing and putting on makeup.“Our products succeed when they become part of daily or weekly patterns,” said CarolBerning, a consumer psychologist who recently retired from Procter & Gamble, the company that sold $76 billion of Tide, Crest and other products last y ear. “Creating positive habits is a huge part of improving our consumers‟ lives, and it‟s essential to making new products commercially viable.”Through experiments and observation, social scientists like Dr. Berning have learned that there is power in tying certain behaviors to habitual cues through relentless advertising. As this new science of habit has emerged, controversies have erupted when the tactics have been used to sell questionable beauty creams or unhealthy foods.31.According to Dr.Curtis,habits like hand washing with soap________.[A] should be further cultivated[B] should be changed gradually[C] are deepiy rooted in history[D] are basically private concerns32.Bottled water,chewing gun and skin moisturizers are mentioned in Paragraph 5 so as to____[A] reveal their impact on people‟habits[B] show the urgent need of daily necessities[C]indicate their effect on people‟buying power[D]manifest the significant role of good habits33.which of the following does NOT belong to products that help create people‟s habits?[A]Tide[B]Crest[C]Colgate[D]Unilver34.From the text wekonw that some of co nsumer‟s habits are developed due to _____[A]perfected art of products[B]automatic behavior creation[C]commercial promotions[D]scientific experiments35.the author‟sattitude toward the influence of advertisement on people‟s habits is____[A]indifferent[B]negative[C]positive[D]biasedText4Many Americans regard the jury system as a concrete expression of crucial democratic values, including the principles that all citizens who meet minimal qualifications of age and literacy are equally competent to serve on juries; that jurors should be selected randomly from a representative cross section of the community; that no citizen should be denied the right to serve on a jury on account of race, religion, sex, or national origin; that defendants are entitled to trial by their peers; and that verdicts should represent the conscience of the community and not just the letter of the law.

1.电影开演时观众中女士和男士人数之比为5:4，开演后无观众入场，放映一小时后，女士的20%，男士的15%离场，则此时在场的女士和男士人数之比为（A ）4:5 (B)1:1 (C)5:4 (D)20:17 (E)85:64 答案：D分析：设电影开始时，女为a 人，男为b 人，有已知条件，a=5x ，b=4x ，从而5x×0.84x×0.85=43.4=20172.某商品的成本为240元,若按该商品标价的8折出售,利润率是15%,则该商品的标价为 (A)276元 (B)331元 (C)345元 (D)360元 (E)400元答案：C分析：设标价为a 元，则售价为0.8a ，由已知0.8a−240240=0.15解得a=345(元)3.三名小孩中有一名学龄前儿童(年龄不足6岁)，他们的年龄都是质数（素数），且依次相差6岁，他们的年龄之和为（A ）21 （B ）27 （C ）33 （D ）39 （E ）51 答案：C分析：设三个儿童的年龄依次为P1，P2，P3（P1<6），若P1=2，则P2=2+6，P3=8+6,不合题意. 若P1=3，则P2=3+6，P3=9+6,不合题意.取P1=5，则P2=5+6=11，P3=11+6=17，即P1，P2，P3皆为质数，符合题意要求，则三个儿童年龄和为5+11+17=334.在右边的表格中，每行为等差数列，每列为等比数列，x+y+z= 2 5/2 3 X 5/4 3/2 A Y 3/4 BCZ答案：A分析：由x ，54，32为等差数列，52,54,y 为等比数列及32，34，z 为等比数列，得 54 - x=32 - 54，y=54×12 , z=34×12 即 x=1 , y = 58 ， z=38 ，1+58+38=25.如图1，在直角三角形ABC 区域内部有座山，现计划从BC 边上的某点D 开凿一条隧道到点A ，要求隧道长度最短，已知AB 长为5km ，则所开凿的隧道AD 的长度约为（A ）4.12km (B)4.22km (C)4.42km (D)4.62km (E)4.92km答案：D分析：由已知BC=√52+122=13，从而12×5×12=12×AD ×13 解得:AD=6013≈4.626.某商店举行店庆活动，顾客消费达到一定数量后，可以在4种赠品中随机选取2件不同的赠品，任意两位顾客所选的赠品中，恰有1件品种相同的概率是（A ） 1/6 （B ） 1/4 （C ）1/3 （D ）1/2 （E ）2/3 答案：E分析：将4种赠品分别用1,2,3,4编号，任意2位顾客任选赠品的总可能性为C 42C 42=36（种） A1表示2位顾客所选赠品中恰有意见相同，且相同赠品为1号赠品，则A1包含的可能性为C 32C 21=6种，从而P(A1)=16.以此类推，A i （i=2,3，4,）表示2位顾客所选赠品中恰有一件相同，且相同，且相同赠品为i 号赠品，则P(A2)=P(A3)=P(A4)= 16 从而所求概率为4×16=237.多项式x3+ax2+bx -6的两个因式是x -1和x -2，则其第三个一次因式为（Ａ）x -6 (B)x -3 (C)x+1 (D)x+2 (E)x+3 答案：B分析：若x 3+a x 2+bx -6=(x -1)(x -2)(x -m),令x=0则有（-1）×（-2）×（-m ）= -6 即m=38.某公司的员工中，拥有本科毕业证、计算机登记证、汽车驾驶证得人数分别为130，110，90.又知只有一种证的人数为140，三证齐全的人数为30，则恰有双证得人数为（A ）45 （B ）50 （C ）52 （D ）65 （E ）100 答案：B分析：如图4所示，公司员工可被分为8部分，为书写方便，这里A 、B 、C 分别代表仅有本科毕业证，仅有计算机等级证，仅有汽车驾驶证人数， A+AB+AC+ABC=130 B+AB+BC+ABC=110 由已知条件：C+AC+BC+ABC=90 A+B+C=140 ABC=30前三个方程得A+B+C+3ABC+2(AB+AC+BC)=330 从而 140+90+2（AB+AC+BC ）=330 AB+AC+BC=50(人)9.甲商店销售某种商品，该商品的进价为每价90元，若每件定价为100元，则一天内能售出500件，在此基础上，定价每增加1元，一天便能少售出10出，甲商店欲获得最大利润，则该商品的定价应为（A ）115元（B ）120元（C ）125元（D ）130元（E ）135元答案：B分析:设定价为100+a （元），由已知条件，利润 l=（100+a ）（500-10a ）-90（500-10a ） = -10a 2+400a+5000 = - 10[(a −20)2-900] 即当a=20时，利润最大.10.已知直线ax -by+3=0(a>0,b>0)过圆x2+4x+y2-2y+1=0的圆心，则a -b 的最大值为（A ）9/16 （B ）11/16 （C ） 3/4 （D ） 9/8 （E ）9/4 答案：D分析：所给圆为(x +2)2+(y −1)2=22,由已知条件 -2a -b+3=0，即b=3-2a 因此ab=a （3-2a ）=-2a 2+3a=-2[(a −34)2-916]即当a = 34,b = 3- 2a = 32时，ab=98为其最大值.11.某大学派出5名志愿者到西部4所中学支教，若每所中学至少有一名志愿者，则不同的分配方案共有（A ）240种（B ）144种（C ）120种（D ）60种（E ）24种答案：A分析：由题意知其中一所学校应分得2人，另外3所各一人.第一步，选一所学校准备分得2人，共有C 41种选法第二步，从5人中选2人到这所学校，共有C 52种选法第三步，安排剩下3人去3所学校，共有3种方式由乘法原理，不同分配方案为C 41C 52×3=240（种）12.某装置的启动密码是由0到9中的3个不同数字组成，连续3次输入错误密码，就会导致该装置永久关闭，一个仅记得密码是由3个不同数字组成的人能够启动此装置的概率为（A ）1/120 （B ）1/168 （C ） 1/240 （D ）1/720 （E ）3/1000 答案：C分析：设Ai （i=1,2,3,）表示第i 次输入正确，则所求概率P=P （A 1∪A 1̅̅̅A 2∪A 1̅̅̅ A 2A 3） =P(A 1)+P(A 1̅̅̅A 2)+P(A 1A 2A 3) =110×9×8+71910×9×8×1719+71910×9×8×718719×1718=3720=124013.某居民小区决定投资15万元修建停车位，据测算，修建一个室内车位的费用为5000元，修建一个室外车位的费用为1000元，考虑到实际因素，计划室外车位的数量不少于室内车位的2倍，也不多于室内车位的3倍，这笔投资最多可建车位的数量为（A ）78 （B ）74 （C ）72 （D ）70 （E ）66 答案：B分析：设建室内停车位x 个，室外停车位y 个，由题意求满足{5000x +1000y ≤1500002x ≤y ≤3x 的最大x+y即7x ≤150,8x ≤150，则x 可能取值为19,20,21，取x=19，得y=55,19+55=74为满足题意的最多车位数. 14.如图2，长方形ABCD 的两条边长分别为8m 和6m ，四边形OEFG 的面积是4m2,则阴影部分的面积为（A ）32m2 （B ）28 m2 （C ）24 m2 （D ）20 m2 （E ）16 m2 答案：B分析：白色区域面积为12BF ∙CD + 12FC ∙AB -4=12CD ∙BC −4=20,从而阴影面积为6×8−20=28（m 2）15.在一次竞猜活动中，设有5关，如果连续通过2关就算成功，小王通过每关的概率都是1/2，他闯关成功的概率为（A ）1/8 （B ） 1/4 （C ） 3/8 （D ）4/8 （E ）19/32 答案：E分析：用Ai （i=1,2,3,4,5）表示第i 关闯关成功，则小王的过关成功率P(A 1A 2∪A 1̅̅̅A 2A 3∪A 1A 2̅̅̅A 3A 4∪A 1 ̅̅̅̅A 2̅̅̅A 3A 4∪A 1A 2 ̅̅̅̅̅A 3̅̅̅A 4A 5∪A 1̅̅̅A 2A 3̅̅̅A 4A 5∪A 1̅̅̅ A 2 ̅̅̅̅̅A 3̅̅̅A 4A 5) = 12∙ 12+ 12∙ 12∙ 12+ 2 ∙12∙ 12∙ 12∙ 12+ 3 ∙ 12∙ 12∙ 12∙ 12∙12= 14 + 18 + 18 + 332 = 1932在此处键入公式。

2010年MBA联考逻辑真题及解析

2010年MBA联考逻辑真题26.针对威胁人类健康的甲型H1N1流感，研究人员研制出了相应的疫苗，尽管这些疫苗是有效的，但某大学研究人员发现，阿司匹林、痉苯基乙酰胺等抑制某些酶的药物会影响疫苗的效果，这位研究人员指出：“如果你使用了阿司匹林或者对乙酰氢基酚，那么你注射疫苗后就必然不会产生良好的抗体反映。

”如果小张注射疫苗后产生了良好的抗体反映，那么根据上述研究结果可以得出以下哪项结论？A．小张服用了阿司匹林，但没有服用对乙酰氢基酚B．小张没有服用阿司匹林，但感染了H1N1流感病毒C．小张服用了阿司匹林，但没有感染H1N1流感病毒D．小张没有服用阿司匹林，也没有服用对乙酰氨基酚E．小张服用了对乙酰氨基酚，但没有服用痉苯基乙酰胺27. 为了调查当前人们的识字水平，其实验者列举了20个词语，请30位文化人士识读，这些人的文化程度都在大专以上。

识读结果显示，多数人只读对3到5个词语，极少数人读对15个以上，甚至有人全部读错。

其中，“蹒跚”的辨识率最高，30人中有19人读对；“呱呱坠地”所有人偶读错。

20个词语的整体误读率接近80%。

该实验者由此得出，当前人们的识字水平并没有提高，甚至有所下降。

以下哪项如果为真，最能对该实验者的结论构成质疑？A．实验者选取的20个词语不具有代表性B．实验者选取的30位识读者均没有博士学位C．实验者选取的20个词语在网络流行语言中不常用D．“呱呱坠地”这个词的读音有些大学老师也经常读错E．实验者选取的30位识读者中约有50%大学成绩不佳28. 域控制器存储了域内的账户，密码和属于这个域的计算机三项信息。

当计算机接入网络时，域控制器首先要鉴别这台计算机是否属于这个域，用户使用的登录账户是否存在，密码是否正确。

如果三项信息均正确，则允许登陆：如果以上信息有一项不正确，那么域控制器就会拒绝这个用户从这台计算机登陆。

小张的登录账号是正确的，但是域控制器拒绝小张的计算机登陆。

基于以上陈述能得出以下哪项结论？A．小张输入的密码是错误的B．小张的计算机不属于这个域C．如果小张的计算机属于这个域，那么他输入的密码是错误的D．只有小张输入的密码是正确的，它的计算机才属于这个域E．如果小张输入的密码是正确的，那么它的计算机属于这个域29. 现在越来越多的人拥有了自己的轿车，但他么明显地缺乏汽车保养的基本知识，这些人会按照维修保养手册或4S店售后服务人员的提示做定期保养。

2010年MBA英语真题答案及详解（阅读、新题型及翻译部分）

002010年MBA英语真题答案及详解（阅读、新题型及翻译部分）The longest bull run in a century of art-market history ended on a dramatic note with a sale of 56 works by Damien Hirst, “Beautiful Inside My Head Forever”， at Sotheby’s in London on September 15th 2008. All but two pieces sold, fetching more than £70m, a record for a sale by a single artist. It was a last victory. As the auctioneer called out bids, in New York one of the oldest banks on Wall Street, Lehman Brothers, filed for bankruptcy。

The world art market had already been losing momentum for a while after rising vertiginously since 2003. At its peak in 2007 it was worth some $65 billion, reckons Clare McAndrew, founder of Arts Economics, a research firm—double the figure five years earlier. Since then it may have come down to $50 billion. But the market generates interest far beyond its size because it brings together great wealth, enormous egos, greed, passion and controversy in a way matched by few other industries。

28. 大气和云层既可以折射也可以吸收部分太阳光，约有一半照射地球的太阳能被地球表面的土地和水面吸收，这一热能值十分巨大。

由此可以得出：地球将会逐渐升温以致融化。

然而，幸亏有一个可以抵消此作用的因素，即：以下哪项作为上述的后续最为恰当？A. 地球发散到外空的热能值与其吸收的热能值相近。

B. 通过季风与洋流，地球赤道的热向两极方向扩散。

C. 在日食期间，由于月球的阻挡，照射到地球的太阳光线明显减少。

D. 地球核心因为热能积聚而一直呈熔岩状态。

E. 由于二氧化碳排放增加，地球的温室效应引人关注。

29. 如果面粉价格继续上涨，佳食面包店的面包成本必将大幅度增加。

在这种情况下，佳食面包店将会考虑以扩大饮料的经验来弥补面包销售利润的下降。

但是，佳食面包店只有保证面包销售利润不下降，才可避免整体收益明显减少。

以下哪项陈述可以从上文逻辑地得出？A. 如果佳食面包店的整体收益减少，它购买面粉的成本将继续增加。

B. 如果佳食面包店的整体收益减少，要么扩大饮料的经营，要么减少面包的销售。

2010年MBA真题-逻辑(附详解)

2010年MBA逻辑真题及答案三、逻辑推理：本大题共30小题，每小题2分,共60分。

从下面每题所给出的五个选项中，只有一项是符合试题要求的。

请在答题卡上所选项的字母涂黑。

1.针对威胁人类健康的甲型H1N1流感，研究人员研制出了相应的疫苗，尽管这些疫苗是有效的，但某大学研究人员发现，阿司匹林，羟苯基乙酰胺等抑制某些酶的药物会影响疫苗的效果，这位研究员指出：“如果你服用了阿司匹林或者乙酰基酚，那么你注射疫苗后就必然不会产生良好的抗体反映。

”【答案】D如果小张注射疫苗后产生了良好的抗体反映，那么根据上述研究结果可以得出一下哪些结论？A.小张服用了阿司匹林，但没有服用对乙酰基酚B.小张服没有用阿司匹林，但感染了H1N1流感病毒C.小张服用了阿司匹林，但没有感染了H1N1流感病毒D.小张服没有用了阿司匹林，也没有服用对乙酰基酚E.小张服用了乙酰基酚，但没有服用羟苯基乙酰胺【解析】本题属于因果型论证推理，正确答案必须从题面论述中直接推理得出。

根据题面论述，“如果服用了阿司匹林或者乙酰基酚，那么注射疫苗后就必然不会产生良好的抗体反映。

”“小张注射疫苗后产生了良好的抗体”。

根据充分条件推理公式，可以得出：小张没有服用阿司匹林并且没有服用乙酰基酚。

所以选项D正确。

2.为了调查当前的人们的识字水平，其饰演者列举了20个词语，请30人识读，这些人的文化程度都在大专以上。

识读结果显示，多数人只读对3到5个词语，极少数人读对15以上，甚至有人全部读错。

其中，“蹒跚”的辨识率最高，30人中有19人读对，“呱呱坠地”所有人都读错，20个词语的整体误读率接近80%，该试验者由此得出，当前人们的识字水平并没有提高，甚至有所下降。

以下哪项如果是真，最能对该实验者的结论构成质疑？【答案】AA.实验者选取的20个词语不具有代表性B.实验者选取的30位识读者均没有博士学位C.实验者选取的20个词语在网络流行语言中不常用D.“呱呱坠地”这个词的读音有些大学老师也经常读错E.实验者选取的30位识读者约有50%人学成绩不佳【解析】实验者的结论是：调查结果（让30个大专以上文化程度的人识读20个词语，出现了很多错误）显示当前人们的识字水平并无提高甚至降低。
