Rather than playing tricks with alternatives presented to participants, we secretly altered the outcomes of their choices, and recorded how they react. For example, in an early study we showed our volunteers pairs of pictures of faces and asked them to choose the most attractive. In some trials, immediately after they made their choice, we asked people to explain the reasons behind their choices.Unknown to them, we sometimes used a double-card magic trick to secretly exchange one face for the other so they ended up with the face they did not choose. Common sense dictates that all of us would notice such a big change in the outcome of a choice. But the result showed that in 75 per cent of the trials our participants were blind to the mismatch, even offering “reasons” for their“choice”.We called this effect “choice blindness”, echoing change blindness,the phenomenon identified by psychologists where a remarkably large number of people fail to spot a major change in their environment. Recall the famous experiments where X asks Y for directions; while Y is struggling to help, X is switched for Z - and. Y fails to notice. Researchers are still pondering the full implications, but it does show how little information we use in daily life, and undermines the idea that we know what is going on around us.When we set out, we aimed to weigh in on the enduring, complicated debate about self-knowledge and intentionality. For all the intimate familiarity we feel we have with decision making, it is very difficult to know about it from the “inside”: one of the great barriers for scientific research is the nature of s ubjectivity.As anyone who has ever been in a verbal disagreement can prove, people tend to give elaborate justifications for their decisions, which we have every reason to believe are nothing more than rationalizations after the event. To prove such people wrong, though, or even provide enough evidence to change their mind, is an entirely different matter: who are you to say what my reasons are?But with choice blindness we drive a large wedge between intentions and actions in the mind. As our participants give us verbal explanations about choices they never made, we can show them beyond doubt - and prove it - that what they say cannot be true. So our experiments offer a unique window into confabulation (the story-telling we do to justify things after the fact) that is otherwise very difficult to come by. We can compare everyday explanations with those under lab conditions, looking for such things as the amount of detail in descriptions, how coherent the narrative is, the emotional tone, or even the timing or flow of the speech. Then we can create a theoretical framework to analyse any kind of exchange.This framework could provide a clinical use for choice blindness: for example, two of our ongoing studies examine how malingering might develop into truesymptoms, and how confabulation might play a role in obsessive-compulsive disorder.Importantly, the effects of choice blindness go beyond snap judgments. Depending on what our volunteers say in response to the mismatched outcomes of choices (whether they give short or long explanations, give numerical rating or labeling, and so on) we found this interaction could change their future preferences to the extent that they come to prefer the previously rejected alternative. This gives us a rare glimpse into the complicated dynamics of self-feedback (“I chose this, I publicly said so, therefore I must like it”), which we suspect lies behind the formation of many everyday preferences.We also want to explore the boundaries of choice blindness. Of course, it will be limited by choices we know to be of great importance in everyday life. Which bride or bridegroom would fail to notice if someone switched their partner at the altar through amazing sleight of hand? Yet there is ample territory between the absurd idea of spouse-swapping, and the results of our early face experiments.For example, in one recent study we invited supermarket customers to choose between two paired varieties of jam and tea. In order to switch each participant’s choice without them noticing, we created two sets of “magical” jars, with lids at both ends and a divider inside. The jars looked normal, but were designed to hold one variety of jam or tea at each end, and could easily be flipped over.Immediately after the participants chose, we asked them to taste their choice again and tell us verbally why they made that choice. Before they did, we turned over the sample containers, so the tasters were given the opposite of what they had intended in their selection. Strikingly, people detected no more than a third of all these trick trials. Even when we switched such remarkably different flavors as spicy cinnamon and apple for bitter grapefruit jam, the participants spotted less than half of all s witches.We have also documented this kind of effect when we simulate online shopping for consumer products such as laptops or cell phones, and even apartments. Our latest tests are exploring moral and political decisions, a domain where reflection and deliberation are supposed to play a central role, but which we believe is perfectly suited to investigating using choice blindness.Throughout our experiments, as well as registering whether our volunteers noticed that they had been presented with the alternative they did not choose, we also quizzed them about their beliefs about their decision processes. How did they think they would feel if they had been exposed to a study like ours? Did they think they would have noticed the switches? Consistently, between 80 and 90 per cent of people said that they believed they would have noticed something was wrong.Gervais, discovers a thing called “lying” and what it can get him. Within days, M ark is rich, famous, and courting the girl of his dreams. And because nobody knows what “lying” is? he goes on, happily living what has become a complete and utter farce.It’s meant to be funny, but it’s also a more serious commentary on us all. As Americans, we like to think we value the truth. Time and time again, public-opinion polls show that honesty is among the top five characteristics we want in a leader, friend, or lover; the world is full of sad stories about the tragic consequences of betrayal. At the same time, deception is all around us. We are lied to by government officials and public figures to a disturbing degree; many of our social relationships are based on little white lies we tell each other. We deceive our children, only to be deceived by them in return. And the average person, says psychologist Robert Feldman, the author of a new book on lying, tells at least three lies in the first 10 minutes of a conversation. “There’s always been a lot of lying,” says Feldman,whose new book, The Liar in Your Life, came out this month. “But I do think we’re seeing a kind of cultural shift where we’re lying more, it’s easier to lie, and in some ways it’s almost more acceptable.”As Paul Ekman, one of Feldman’s longtime lying colleagues and the inspiration behind the Fox IV series “Lie To Me” defines it,a liar is a person who “intends to mislead,”“deliberately,” without being asked to do so by the target of the lie. Which doesn’t mean that all lies are equally toxic: some are simply habitual –“My pleasure!”-- while others might be well-meaning white lies. But each, Feldman argues, is harmful, because of the standard it creates. And the more lies we tell, even if th ey’re little white lies, the more deceptive we and society become.We are a culture of liars, to put it bluntly, with deceit so deeply ingrained in our mind that we hardly even notice we’re engaging in it. Junk e-mail, deceptive advertising, the everyday p leasantries we don’t really mean –“It’s so great to meet you! I love that dress”– have, as Feldman puts it, become “a white noise we’ve learned to neglect.” And Feldman also argues that cheating is more common today than ever. The Josephson Institute, a nonprofit focused on youth ethics, concluded in a 2008 survey of nearly 30,000 high school students that “cheating in school continues to be rampant, and it’s getting worse.” In that survey, 64 percent of students said they’d cheated on a test during the past year, up from 60 percent in 2006. Another recent survey, by Junior Achievement, revealed that more than a third of teens believe lying, cheating, or plagiarizing can be necessary to succeed, while a brand-new study, commissioned by the publishers of Feldman’s book, shows that 18-to 34-year-olds--- those of us fully reared in this lying culture --- deceive more frequently than the general population.Teaching us to lie is not the purpose of Feldman’s book. His subtitle, in fact, is “the way to truthful relationships.” But if his book teaches us anything, it’s that we should sharpen our skills — and use them with abandon.Liars get what they want. They avoid punishment, and they win others’ affection. Liars make themselves sound smart and intelligent, they attain power over those of us who believe them, and they often use their lies to rise up in the professional world. Many liars have fun doing it. And many more take pride in getting away with it.As Feldman notes, there is an evolutionary basis for deception: in the wild, animals use deception to “play dead” when threatened. But in the modem world, the motives of our lying are more selfish. Research has linked socially successful people to those who are good liars. Students who succeed academically get picked for the best colleges, despite the fact that, as one recent Duke University study found, as many as 90 percent of high-schoolers admit to cheating. Even lying adolescents are more popular among their peers.And all it takes is a quick flip of the remote to see how our public figures fare when they get caught in a lie: Clinton keeps his wife and goes on to become a national hero. Fabricating author James Frey gets a million-dollar book deal. Eliot Spitzer’s wife stands by his side, while “Appalachian hiker” Mark Sanford still gets to keep his post. If everyone else is being rewarded for lying,don’t we need to lie, too, just to keep up?But what’s funny is that even as we admit to being liars, study after study shows that most of us believe we can tell when others are lying to us. And while lying may be easy, spotting a liar is far from it. A nervous sweat or shifty eyes can certainly mean a person’s uncomfortable, but it doesn’t necessarily mean they’re lying. Gaze aversion, meanwhile, has more to do with shyness than actual deception. Even polygraph machines are unreliable. And according to one study, by researcher Bella DePaulo, we’re only able to differentiate a lie from truth only 47 percent of the time, less than if we guessed randomly. “Basically everything we’ve heard about catching a liar is wrong,” says Feldman, who heads the College of Social and Behavioral Sciences at the University of Massachusetts, Amherst.Ekman, meanwhile, has spent decades studying micro-facial expressions of liars: the split-second eyebrow arch that shows surprise when a spouse asks who was on the phone; the furrowed nose that gives away a hint of disgust when a person says “I love you.” He’s trained everyone from the Secret Service to the TSA, and believes that with close study, it’s possible to identify those tiny emotions. The hard part, of course, is proving them. “A lot of times, it’s easier to believe,” says Feldman. “It takes a lot ofThere were, however, different explanations of this unhappy fact. Sean Pidgeon put the blame on “humanities departments who are responsible for the leftist politics that still turn people off.” Kedar Kulkarni blamed “the absence of a culture that privileges Learning to improve oneself as a human being.” Bethany blamed universities, which because they are obsessed with “maintaining funding” default on th e obligation to produce “well rounded citizens.” Matthew blamed no one,because i n his view the report’s priorities are just what they should be: “When a poet creates a vaccine or a tangible good that can be produced by a Fortune 500 company, I’ll rescind my comment.”Although none of these commentators uses the word, the issue they implicitly raise is justification. How does one justify funding the arts and humanities? It is clear which justifications are not available. You cannot argue that the arts and humanities are able to support themselves through grants and private donations. You cannot argue that a state’s economy will benefit by a new reading of “Hamlet.” You can’t argue -- well you can, but it won’t fly -- that a graduate who is well-versed in the history of Byzantine art will be attractive to employers (unless the employer is a museum). You can talk as Bethany does about “well rounded citizens,” but that ideal belongs to an earlier period, when the ability to refer knowledgeably to Shakespeare or Gibbon or the Thirty Years War had some cash value (the sociologists call it cultural capital). Nowadays, larding your conversations with small bits of erudition is more likely to irritate than to win friends and influence people.At one time justification of the arts and humanities was unnecessary because, as Anthony Kronman puts it in a new book, “Education’s End: Why Our Colleges and Universities Have Given Up on the Meaning of Life,” it was assumed that “a college was above all a place for the training of character, for the nurturing of those intellectual and moral habits that together from the basis for living the best life one can.”It followed that the realization of this goal required an immersion in the great texts of literature, philosophy and history even to the extent of memorizing them, for “to acquire a text by memory is to fix in one’s mind the image and example of the author and his subject.”It is to a version of this old ideal that Kronman would have us return, not because of a professional investment in the humanities (he is a professor of law and a former dean of the Yale Law School), but because he believes that only the humanities can address “the crisis of spirit we now confront” and “restore the wonder which those who have glimpsed the human condition have always felt, and which our scientific civilization, with its gadgets and discoveries, obscures.”As this last quotation makes clear, Kronman is not so much mounting a defense ofthe humanities as he is mounting an attack on everything else. Other spokespersons for the humanities argue for their utility by connecting them (in largely unconvincing ways) to the goals of science, technology and the building of careers. Kronman, however, identifies science, technology and careerism as impediments to living a life with meaning. The real enemies, he declares,are “the careerism that distracts from life as a whole” and “the blind acceptance of science and technology that disguise and deny our human condition.” These false idols,he says,block the way to understanding. We must turn to the humanities if we are to “meet the need for meaning in an age of vast but pointless powers,”for only the humanities can help us recover the urgency of “the question of what living is for.”The humanities do this, Kronman explains, by exposing students to “a range of texts that express with matchless power a number of competing answers to this question.” In the course of this program —Kronman calls it “secular humanism”—students will be moved “to consider which alternatives lie closest to their own evolving sense of self?” As they survey “the different ways of living that have been held up by different authors,” they will be encouraged “to enter as deeply as they can into the experiences, ideas, and values that give each its permanent appeal.” And not only would such a “revitalized humanism” contribute to the growth of the self,it “would put the conventional pieties of our moral and political world in question” and “bring what is hidden into the open — the highest goal of the humanities and the first responsibility of every teache r.”Here then is a justification of the humanities that is neither strained (reading poetry contributes to the state’s bottom line) nor crassly careerist. It is a stirring vision that promises the highest reward to those who respond to it. Entering into a conversation with the great authors of the western tradition holds out the prospect of experiencing “a kind of immortality” and achieving “a position immune to the corrupting powers of time.”Sounds great, but I have my doubts. Does it really work that way? Do the humanities ennoble? And for that matter, is it the business of the humanities, or of any other area of academic study, to save us?The answer in both cases, I think, is no. The premise of secular humanism (or of just old-fashioned humanism) is that the examples of action and thought portrayed in the enduring works of literature, philosophy and history can create in readers the desire to emulate them. Philip Sydney put it as well as anyone ever has when he asks (in “The Defense of Poesy” 1595), “Who reads Aeneas carrying old Anchises on his back that wishes not it was his fortune to perform such an excellent act?” Thrill to this picture of42.What does Anthony Kronman oppose in the process to strive for meaningful life?A.Secular humanism.B. Careerism.C. Revitalized humanismD. Cultural capital.43.Which of the following is NOT mentioned in this article?A.Sidney Carton killed himself.B.A new reading of Hamlet may not benefit economy.C.Faust was not willing to sell his soul.D.Philip Sydney wrote The Defense of Poesy.44.Which is NOT true about the author?A.At the time of writing, he has been in the field of the humanities for 45 years.B.He thinks the humanities are supposed to save at least those who study them.C.He thinks teachers and students of the humanities just learn how to analyze literary effects and to distinguish between different accounts of the foundations of knowledge.D.He thin ks Kronman’s remarks compromise the object its supposed praise.45.Which statement could best summarize this article?A.The arts and humanities fail to produce well-rounded citizens.B.The humanities won’t save us because humanities departments are too leftist.C.The humanities are expected to train character and nurture those intellectual andmoral habits for living a life with meaning.D.The humanities don’t bring about effects in the world but just give pleasure to those who enjoy them.Passage fourJust over a decade into the 21st century, women’s progress can be celebrated across a range of fields. They hold the highest political offices from Thailand to Brazil, Costa Rica to Australia. A woman holds the top spot at the International Monetary Fund; another won the Nobel Prize in economics. Self-made billionaires in Beijing, tech innovators in Silicon Valley, pioneering justices in Ghana—in these and countless other areas, women are leaving their mark.But hold the applause. In Saudi Arabia, women aren’t allowed to drive. In Pakistan, 1,000 women die in honor killings every year. In the developed world, women lag behind men in pay and political power. The poverty rate among women in the U.S. rose to 14.5% last year.To measure the state of women’s progress. Newsweek ranked 165countries, looking at five areas that affect women’s lives; treatment under the law, workforce participation, political power, and access to education and health care. Analyzing datafrom the United Nations and the World Economic Forum, among others, and consulting with experts and academics, we measured 28 factors to come up with our rankings.Countries with the highest scores tend to be clustered in the West, where gender discrimination is against the law, and equal rights are constitutionally enshrined. But there were some surprises. Some otherwise high-ranking countries had relatively low scores for political representation. Canada ranked third overall but 26th in power, behind countries such as Cuba and Burundi. Does this suggest that a woman in a nation’s top office translates to better lives for women in general? Not exactly.“Trying to quantify or measure the impact of women in politics is hard because in very few countries have there been enough women in politics to make a difference,” says Anne-Marie Goetz, peace and security adviser for U.N. Women.Of course, no index can account for everything. Declaring that one country is better than another in the way that it treats more than half its citizens means relying on broad strokes and generalities. Some things simply can’t be measured.And cross-cultural comparisons can t account for difference of opinion.Certain conclusions are nonetheless clear. For one thing, our index backs up a simple but profound statement made by Hillary Clinton at the recent Asia-Pacific Economic Cooperation summit. “When we liberate the economic potential of women, we elevate the economic performance of communities, nations, and the world,”she said. “There’s a simulative effect that kicks in when women have greater access to jobs and the economic lives of our countries: Greater political stability. Fewer military conflicts. More food. More educational opportunity for children. By harnessing the economic potential of all women, we boost opportunity for all people.”46.What does the author think about women’s progress so far?A.It still leaves much to be desired.B.It is too remarkable to be measured.C.It has greatly changed women's fate.D.It is achieved through hard struggle.47.In what countries have women made the greatest progress?A.Where women hold key posts in government.B.Where women’s rights are protected by law.C.Where women’s participation in management is high.D.Where women enjoy better education and health care.48.What do Newsweek rankings reveal about women in Canada?A.They care little about political participation.B.They are generally treated as equals by men.C.They have a surprisingly low social status.D.They are underrepresented in politics.49.What does Anne-Marie Goetz think of a woman being in a nation's top office?A.It does not necessarily raise women's political awareness.B.It does not guarantee a better life for the nation's women.C.It enhances women's status.D.It boosts women's confidence.50.What does Hillary Clinton suggest we do to make the world a better place?A.Give women more political power.B.Stimulate women's creativity.C.Allow women access to education.D.Tap women's economic potential.Passage fiveThe idea that government should regulate intellectual property through copyrights and patents is relatively recent in human history, and the precise details of what intellectual property is protected for how long vary across nations and occasionally change. There are two standard sociological justifications for patents or copyrights: They reward creators for their labor, and they encourage greater creativity. Both of these are empirical claims that can be tested scientifically and could be false in some realms.Consider music. Star performers existed before the 20th century, such as Franz Liszt and Niccolo Paganini, but mass media produced a celebrity system promoting a few stars whose music was not necessarily the best or most diverse. Copyright provides protection for distribution companies and for a few celebrities, thereby helping to support the industry as currently defined, but it may actually harm the majority of performers. This is comparable to Anatole France's famous irony, "The law, in its majestic equality, forbids the rich as well as the poor to sleep under bridges." In theory, copyright covers the creations of celebrities and obscurities equally, but only major distribution companies have the resources to defend their property rights in court. In a sense, this is quite fair, because nobody wants to steal unpopular music, but by supporting the property rights of celebrities, copyright strengthens them as a class in contrast to anonymous musicians.Internet music file sharing has become a significant factor in the social lives of children, who download bootleg music tracks for their own use and to give as gifts to friends. If we are to believe one recent poll done by a marketing firm rather than social。

2018年华南理工大学研究生入学考试专业课真题626_英语综合水平测试
626华南理工大学2018 年攻读硕士学位研究生入学考试试卷(试卷上做答无效,请在答题纸上做答,试后本卷必须与答题纸一同交回)科目名称:英语综合水平测试适用专业:外国语言文学performances. Rather than playing tricks with alternatives presented to participants, we secretly altered the outcomes of their choices, and recorded how they react. For example, in an early study we showed our volunteers pairs of pictures of faces and asked them to choose the most attractive. In some trials, immediately after they made their choice, we asked people to explain the reasons behind their choices.Unknown to them, we sometimes used a double-card magic trick to secretly exchange one face for the other so they ended up with the face they did not choose. Common sense dictates that all of us would notice such a big change in the outcome of a choice. But the result showed that in 75 per cent of the trials our participants were blind to the mismatch, even offering “reasons” for their“choice”.We called this effect “choice blindness”, echoing change blindness,the phenomenon identified by psychologists where a remarkably large number of people fail to spot a major change in their environment. Recall the famous experiments where X asks Y for directions; while Y is struggling to help, X is switched for Z - and. Y fails to notice. Researchers are still pondering the full implications, but it does show how little information we use in daily life, and undermines the idea that we know what is going on around us.When we set out, we aimed to weigh in on the enduring, complicated debate about self-knowledge and intentionality. For all the intimate familiarity we feel we have with decision making, it is very difficult to know about it from the “inside”: one of the great barriers for scientific research is the nature of s ubjectivity.As anyone who has ever been in a verbal disagreement can prove, people tend to give elaborate justifications for their decisions, which we have every reason to believe are nothing more than rationalizations after the event. To prove such people wrong, though, or even provide enough evidence to change their mind, is an entirely different matter: who are you to say what my reasons are?But with choice blindness we drive a large wedge between intentions and actions in the mind. As our participants give us verbal explanations about choices they never made, we can show them beyond doubt - and prove it - that what they say cannot be true. So our experiments offer a unique window into confabulation (the story-telling we do to justify things after the fact) that is otherwise very difficult to come by. We can compare everyday explanations with those under lab conditions, looking for such things as the amount of detail in descriptions, how coherent the narrative is, the emotional tone, or even the timing or flow of the speech. Then we can create a theoretical framework to analyse any kind of exchange.This framework could provide a clinical use for choice blindness: for example, two of our ongoing studies examine how malingering might develop into truesymptoms, and how confabulation might play a role in obsessive-compulsive disorder.Importantly, the effects of choice blindness go beyond snap judgments. Depending on what our volunteers say in response to the mismatched outcomes of choices (whether they give short or long explanations, give numerical rating or labeling, and so on) we found this interaction could change their future preferences to the extent that they come to prefer the previously rejected alternative. This gives us a rare glimpse into the complicated dynamics of self-feedback (“I chose this, I publicly said so, therefore I must like it”), which we suspect lies behind the formation of many everyday preferences.We also want to explore the boundaries of choice blindness. Of course, it will be limited by choices we know to be of great importance in everyday life. Which bride or bridegroom would fail to notice if someone switched their partner at the altar through amazing sleight of hand? Yet there is ample territory between the absurd idea of spouse-swapping, and the results of our early face experiments.For example, in one recent study we invited supermarket customers to choose between two paired varieties of jam and tea. In order to switch each participant’s choice without them noticing, we created two sets of “magical” jars, with lids at both ends and a divider inside. The jars looked normal, but were designed to hold one variety of jam or tea at each end, and could easily be flipped over.Immediately after the participants chose, we asked them to taste their choice again and tell us verbally why they made that choice. Before they did, we turned over the sample containers, so the tasters were given the opposite of what they had intended in their selection. Strikingly, people detected no more than a third of all these trick trials. Even when we switched such remarkably different flavors as spicy cinnamon and apple for bitter grapefruit jam, the participants spotted less than half of all s witches.We have also documented this kind of effect when we simulate online shopping for consumer products such as laptops or cell phones, and even apartments. Our latest tests are exploring moral and political decisions, a domain where reflection and deliberation are supposed to play a central role, but which we believe is perfectly suited to investigating using choice blindness.Throughout our experiments, as well as registering whether our volunteers noticed that they had been presented with the alternative they did not choose, we also quizzed them about their beliefs about their decision processes. How did they think they would feel if they had been exposed to a study like ours? Did they think they would have noticed the switches? Consistently, between 80 and 90 per cent of people said that they believed they would have noticed something was wrong.Gervais, discovers a thing called “lying” and what it can get him. Within days, M ark is rich, famous, and courting the girl of his dreams. And because nobody knows what “lying” is? he goes on, happily living what has become a complete and utter farce.It’s meant to be funny, but it’s also a more serious commentary on us all. As Americans, we like to think we value the truth. Time and time again, public-opinion polls show that honesty is among the top five characteristics we want in a leader, friend, or lover; the world is full of sad stories about the tragic consequences of betrayal. At the same time, deception is all around us. We are lied to by government officials and public figures to a disturbing degree; many of our social relationships are based on little white lies we tell each other. We deceive our children, only to be deceived by them in return. And the average person, says psychologist Robert Feldman, the author of a new book on lying, tells at least three lies in the first 10 minutes of a conversation. “There’s always been a lot of lying,” says Feldman,whose new book, The Liar in Your Life, came out this month. “But I do think we’re seeing a kind of cultural shift where we’re lying more, it’s easier to lie, and in some ways it’s almost more acceptable.”As Paul Ekman, one of Feldman’s longtime lying colleagues and the inspiration behind the Fox IV series “Lie To Me” defines it,a liar is a person who “intends to mislead,”“deliberately,” without being asked to do so by the target of the lie. Which doesn’t mean that all lies are equally toxic: some are simply habitual –“My pleasure!”-- while others might be well-meaning white lies. But each, Feldman argues, is harmful, because of the standard it creates. And the more lies we tell, even if th ey’re little white lies, the more deceptive we and society become.We are a culture of liars, to put it bluntly, with deceit so deeply ingrained in our mind that we hardly even notice we’re engaging in it. Junk e-mail, deceptive advertising, the everyday p leasantries we don’t really mean –“It’s so great to meet you! I love that dress”– have, as Feldman puts it, become “a white noise we’ve learned to neglect.” And Feldman also argues that cheating is more common today than ever. The Josephson Institute, a nonprofit focused on youth ethics, concluded in a 2008 survey of nearly 30,000 high school students that “cheating in school continues to be rampant, and it’s getting worse.” In that survey, 64 percent of students said they’d cheated on a test during the past year, up from 60 percent in 2006. Another recent survey, by Junior Achievement, revealed that more than a third of teens believe lying, cheating, or plagiarizing can be necessary to succeed, while a brand-new study, commissioned by the publishers of Feldman’s book, shows that 18-to 34-year-olds--- those of us fully reared in this lying culture --- deceive more frequently than the general population.Teaching us to lie is not the purpose of Feldman’s book. His subtitle, in fact, is “the way to truthful relationships.” But if his book teaches us anything, it’s that we should sharpen our skills — and use them with abandon.Liars get what they want. They avoid punishment, and they win others’ affection. Liars make themselves sound smart and intelligent, they attain power over those of us who believe them, and they often use their lies to rise up in the professional world. Many liars have fun doing it. And many more take pride in getting away with it.As Feldman notes, there is an evolutionary basis for deception: in the wild, animals use deception to “play dead” when threatened. But in the modem world, the motives of our lying are more selfish. Research has linked socially successful people to those who are good liars. Students who succeed academically get picked for the best colleges, despite the fact that, as one recent Duke University study found, as many as 90 percent of high-schoolers admit to cheating. Even lying adolescents are more popular among their peers.And all it takes is a quick flip of the remote to see how our public figures fare when they get caught in a lie: Clinton keeps his wife and goes on to become a national hero. Fabricating author James Frey gets a million-dollar book deal. Eliot Spitzer’s wife stands by his side, while “Appalachian hiker” Mark Sanford still gets to keep his post. If everyone else is being rewarded for lying,don’t we need to lie, too, just to keep up?But what’s funny is that even as we admit to being liars, study after study shows that most of us believe we can tell when others are lying to us. And while lying may be easy, spotting a liar is far from it. A nervous sweat or shifty eyes can certainly mean a person’s uncomfortable, but it doesn’t necessarily mean they’re lying. Gaze aversion, meanwhile, has more to do with shyness than actual deception. Even polygraph machines are unreliable. And according to one study, by researcher Bella DePaulo, we’re only able to differentiate a lie from truth only 47 percent of the time, less than if we guessed randomly. “Basically everything we’ve heard about catching a liar is wrong,” says Feldman, who heads the College of Social and Behavioral Sciences at the University of Massachusetts, Amherst.Ekman, meanwhile, has spent decades studying micro-facial expressions of liars: the split-second eyebrow arch that shows surprise when a spouse asks who was on the phone; the furrowed nose that gives away a hint of disgust when a person says “I love you.” He’s trained everyone from the Secret Service to the TSA, and believes that with close study, it’s possible to identify those tiny emotions. The hard part, of course, is proving them. “A lot of times, it’s easier to believe,” says Feldman. “It takes a lot ofThere were, however, different explanations of this unhappy fact. Sean Pidgeon put the blame on “humanities departments who are responsible for the leftist politics that still turn people off.” Kedar Kulkarni blamed “the absence of a culture that privileges Learning to improve oneself as a human being.” Bethany blamed universities, which because they are obsessed with “maintaining funding” default on th e obligation to produce “well rounded citizens.” Matthew blamed no one,because i n his view the report’s priorities are just what they should be: “When a poet creates a vaccine or a tangible good that can be produced by a Fortune 500 company, I’ll rescind my comment.”Although none of these commentators uses the word, the issue they implicitly raise is justification. How does one justify funding the arts and humanities? It is clear which justifications are not available. You cannot argue that the arts and humanities are able to support themselves through grants and private donations. You cannot argue that a state’s economy will benefit by a new reading of “Hamlet.” You can’t argue -- well you can, but it won’t fly -- that a graduate who is well-versed in the history of Byzantine art will be attractive to employers (unless the employer is a museum). You can talk as Bethany does about “well rounded citizens,” but that ideal belongs to an earlier period, when the ability to refer knowledgeably to Shakespeare or Gibbon or the Thirty Years War had some cash value (the sociologists call it cultural capital). Nowadays, larding your conversations with small bits of erudition is more likely to irritate than to win friends and influence people.At one time justification of the arts and humanities was unnecessary because, as Anthony Kronman puts it in a new book, “Education’s End: Why Our Colleges and Universities Have Given Up on the Meaning of Life,” it was assumed that “a college was above all a place for the training of character, for the nurturing of those intellectual and moral habits that together from the basis for living the best life one can.”It followed that the realization of this goal required an immersion in the great texts of literature, philosophy and history even to the extent of memorizing them, for “to acquire a text by memory is to fix in one’s mind the image and example of the author and his subject.”It is to a version of this old ideal that Kronman would have us return, not because of a professional investment in the humanities (he is a professor of law and a former dean of the Yale Law School), but because he believes that only the humanities can address “the crisis of spirit we now confront” and “restore the wonder which those who have glimpsed the human condition have always felt, and which our scientific civilization, with its gadgets and discoveries, obscures.”As this last quotation makes clear, Kronman is not so much mounting a defense ofthe humanities as he is mounting an attack on everything else. Other spokespersons for the humanities argue for their utility by connecting them (in largely unconvincing ways) to the goals of science, technology and the building of careers. Kronman, however, identifies science, technology and careerism as impediments to living a life with meaning. The real enemies, he declares,are “the careerism that distracts from life as a whole” and “the blind acceptance of science and technology that disguise and deny our human condition.” These false idols,he says,block the way to understanding. We must turn to the humanities if we are to “meet the need for meaning in an age of vast but pointless powers,”for only the humanities can help us recover the urgency of “the question of what living is for.”The humanities do this, Kronman explains, by exposing students to “a range of texts that express with matchless power a number of competing answers to this question.” In the course of this program —Kronman calls it “secular humanism”—students will be moved “to consider which alternatives lie closest to their own evolving sense of self?” As they survey “the different ways of living that have been held up by different authors,” they will be encouraged “to enter as deeply as they can into the experiences, ideas, and values that give each its permanent appeal.” And not only would such a “revitalized humanism” contribute to the growth of the self,it “would put the conventional pieties of our moral and political world in question” and “bring what is hidden into the open — the highest goal of the humanities and the first responsibility of every teache r.”Here then is a justification of the humanities that is neither strained (reading poetry contributes to the state’s bottom line) nor crassly careerist. It is a stirring vision that promises the highest reward to those who respond to it. Entering into a conversation with the great authors of the western tradition holds out the prospect of experiencing “a kind of immortality” and achieving “a position immune to the corrupting powers of time.”Sounds great, but I have my doubts. Does it really work that way? Do the humanities ennoble? And for that matter, is it the business of the humanities, or of any other area of academic study, to save us?The answer in both cases, I think, is no. The premise of secular humanism (or of just old-fashioned humanism) is that the examples of action and thought portrayed in the enduring works of literature, philosophy and history can create in readers the desire to emulate them. Philip Sydney put it as well as anyone ever has when he asks (in “The Defense of Poesy” 1595), “Who reads Aeneas carrying old Anchises on his back that wishes not it was his fortune to perform such an excellent act?” Thrill to this picture of42.What does Anthony Kronman oppose in the process to strive for meaningful life?A.Secular humanism.B. Careerism.C. Revitalized humanismD. Cultural capital.43.Which of the following is NOT mentioned in this article?A.Sidney Carton killed himself.B.A new reading of Hamlet may not benefit economy.C.Faust was not willing to sell his soul.D.Philip Sydney wrote The Defense of Poesy.44.Which is NOT true about the author?A.At the time of writing, he has been in the field of the humanities for 45 years.B.He thinks the humanities are supposed to save at least those who study them.C.He thinks teachers and students of the humanities just learn how to analyze literary effects and to distinguish between different accounts of the foundations of knowledge.D.He thin ks Kronman’s remarks compromise the object its supposed praise.45.Which statement could best summarize this article?A.The arts and humanities fail to produce well-rounded citizens.B.The humanities won’t save us because humanities departments are too leftist.C.The humanities are expected to train character and nurture those intellectual andmoral habits for living a life with meaning.D.The humanities don’t bring about effects in the world but just give pleasure to those who enjoy them.Passage fourJust over a decade into the 21st century, women’s progress can be celebrated across a range of fields. They hold the highest political offices from Thailand to Brazil, Costa Rica to Australia. A woman holds the top spot at the International Monetary Fund; another won the Nobel Prize in economics. Self-made billionaires in Beijing, tech innovators in Silicon Valley, pioneering justices in Ghana—in these and countless other areas, women are leaving their mark.But hold the applause. In Saudi Arabia, women aren’t allowed to drive. In Pakistan, 1,000 women die in honor killings every year. In the developed world, women lag behind men in pay and political power. The poverty rate among women in the U.S. rose to 14.5% last year.To measure the state of women’s progress. Newsweek ranked 165countries, looking at five areas that affect women’s lives; treatment under the law, workforce participation, political power, and access to education and health care. Analyzing datafrom the United Nations and the World Economic Forum, among others, and consulting with experts and academics, we measured 28 factors to come up with our rankings.Countries with the highest scores tend to be clustered in the West, where gender discrimination is against the law, and equal rights are constitutionally enshrined. But there were some surprises. Some otherwise high-ranking countries had relatively low scores for political representation. Canada ranked third overall but 26th in power, behind countries such as Cuba and Burundi. Does this suggest that a woman in a nation’s top office translates to better lives for women in general? Not exactly.“Trying to quantify or measure the impact of women in politics is hard because in very few countries have there been enough women in politics to make a difference,” says Anne-Marie Goetz, peace and security adviser for U.N. Women.Of course, no index can account for everything. Declaring that one country is better than another in the way that it treats more than half its citizens means relying on broad strokes and generalities. Some things simply can’t be measured.And cross-cultural comparisons can t account for difference of opinion.Certain conclusions are nonetheless clear. For one thing, our index backs up a simple but profound statement made by Hillary Clinton at the recent Asia-Pacific Economic Cooperation summit. “When we liberate the economic potential of women, we elevate the economic performance of communities, nations, and the world,”she said. “There’s a simulative effect that kicks in when women have greater access to jobs and the economic lives of our countries: Greater political stability. Fewer military conflicts. More food. More educational opportunity for children. By harnessing the economic potential of all women, we boost opportunity for all people.”46.What does the author think about women’s progress so far?A.It still leaves much to be desired.B.It is too remarkable to be measured.C.It has greatly changed women's fate.D.It is achieved through hard struggle.47.In what countries have women made the greatest progress?A.Where women hold key posts in government.B.Where women’s rights are protected by law.C.Where women’s participation in management is high.D.Where women enjoy better education and health care.48.What do Newsweek rankings reveal about women in Canada?A.They care little about political participation.B.They are generally treated as equals by men.C.They have a surprisingly low social status.D.They are underrepresented in politics.49.What does Anne-Marie Goetz think of a woman being in a nation's top office?A.It does not necessarily raise women's political awareness.B.It does not guarantee a better life for the nation's women.C.It enhances women's status.D.It boosts women's confidence.50.What does Hillary Clinton suggest we do to make the world a better place?A.Give women more political power.B.Stimulate women's creativity.C.Allow women access to education.D.Tap women's economic potential.Passage fiveThe idea that government should regulate intellectual property through copyrights and patents is relatively recent in human history, and the precise details of what intellectual property is protected for how long vary across nations and occasionally change. There are two standard sociological justifications for patents or copyrights: They reward creators for their labor, and they encourage greater creativity. Both of these are empirical claims that can be tested scientifically and could be false in some realms.Consider music. Star performers existed before the 20th century, such as Franz Liszt and Niccolo Paganini, but mass media produced a celebrity system promoting a few stars whose music was not necessarily the best or most diverse. Copyright provides protection for distribution companies and for a few celebrities, thereby helping to support the industry as currently defined, but it may actually harm the majority of performers. This is comparable to Anatole France's famous irony, "The law, in its majestic equality, forbids the rich as well as the poor to sleep under bridges." In theory, copyright covers the creations of celebrities and obscurities equally, but only major distribution companies have the resources to defend their property rights in court. In a sense, this is quite fair, because nobody wants to steal unpopular music, but by supporting the property rights of celebrities, copyright strengthens them as a class in contrast to anonymous musicians.Internet music file sharing has become a significant factor in the social lives of children, who download bootleg music tracks for their own use and to give as gifts to friends. If we are to believe one recent poll done by a marketing firm rather than social。
