单选题Many people talked of the 288,000 new jobs the Labor Department reported for June, along with the drop in the unemployment rate to 6.1 percent, as good news. And they were right. For now it appears the economy is creating jobs at a decent pace. We still have a long way to go to get back to full employment, but at least we are now finally moving forward at a faster pace. However, there is another important part of the jobs picture that was largely overlooked. There was a big jump in the number of people who report voluntarily working part-time. This figure is now 830,000 (4.4 percent) above its year ago level. Before explaining the connection to the Obamacare, it is worth making an important distinction. Many people who work part-time jobs actually want fulltime jobs. They take part-time work because this is all they can get. An increase in involuntary part-time work is evidence of weakness in the labor market and it means that many people will be having a very hard time making ends meet. There was an increase in involuntary part-time in June, but the general direction has been down. Involuntary part-time employment is still far higher than before the recession, but it is down by 640,000 (7.9 percent) from its year ago level. We know the difference between voluntary and involuntary part-time employment because people tell us. The survey used by the Labor Department asks people if they worked less than 35 hours in the reference week. If the answer is "yes," they are classified as working part-time. The survey then asks whether they worked less than 35 hours in that week because they wanted to work less than full time or because they had no choice. They are only classified as voluntary part-time workers if they tell the survey taker they chose to work less than 35 hours a week. The issue of voluntary part-time relates to Obamacare because one of the main purposes was to allow people to get insurance outside of employment. For many people, especially those with serious health conditions or family members with serious health conditions, before Obamacare the only way to get insurance was through a job that provided health insurance. However, Obamacare has allowed more than 12 million people to either get insurance through Medicaid or the exchanges. These are people who may previously have felt the need to get a full-time job that provided insurance in order to cover themselves and their families. With Obamacare there is no longer a link between employment and insurance.

单选题Institutions of higher learning must move, as the historian Walter Russell Mead puts it, from a model of "time served" to a model of "stuff learned." Because increasingly the world does not care what you know. Everything is on Google. The world only cares, and will only pay for, what you can do with what you know. And therefore it will not pay for a C-plus in chemistry, just because your state college considers that a passing grade and was willing to give you a diploma. We"re moving to a more competency-based world, where there will be less interest in how you acquired the competency and more demand to prove that you mastered the competency. Therefore, we have to get beyond the current system of information and delivery—the professorial "sage on the stage" and students taking notes, followed by a superficial assessment, to one in which students are asked and empowered to master more basic material online at their own pace, and the classroom becomes a place where the application of that knowledge can be honed through lab experiments and discussions with the professor. There seemed to be a strong consensus that this "blended model" combining online lectures with a teacher-led classroom experience was the ideal. Last fall, San Jose State used the online lectures and interactive exercises of MIT"s introductory online Circuits and Electronics course. Students would watch the MIT lectures and do the exercises at home. Then in class, the first 15 minutes were reserved for questions and answers with the San Jose State professor, and the last 45 were devoted to problem-solving and discussion. Preliminary numbers indicate that those passing the class went from nearly 60 percent to about 90 percent. We demand that plumbers and kindergarten teachers be certified to do what they do, but there is no requirement that college professors know how to teach. No more . The world of MOOCs (Massive Open Online Courses) is creating a competition that will force every professor to improve his or her pedagogy or face an online competitor. Bottom line: There is still huge value in the residential college experience and the teacher-student and student-student interactions it facilitates. But to thrive, universities will have to nurture even more of those unique experiences while blending in technology to improve education outcomes in measurable ways at lower costs. We still need more research on what works, but standing still is not an option.

单选题Many Americans harbor a grossly distorted and exaggerated view of most of the risks surrounding food. Fergus Clydesdale, head of the department of food science and nutrition at the University of Massachusetts-Amherst, says bluntly that if the dangers from bacterially contaminated chicken were as great as some people believe, "the streets would be littered with people lying here and there." Though the public increasingly demands no-risk food, there is no such thing, since it has been proved that up to 10% of a plant"s weight is made up of natural pesticides. Bruce Ames, chairman of the biochemistry department at the University of California, Berkeley, says: "Since plants do not have jaws or teeth to protect themselves, they employ chemical warfare." And many naturally produced chemicals, though occurring in tiny amounts, prove in laboratory tests to be strong carcinogens—a substance which can cause cancer. Mushrooms might be banned if they were judged by the same standards that apply to food additives. Declares Christina Stark, a nutritionist at Cornell University: "We"ve got far worse natural chemicals in the food supply than anything man-made." Yet the issues are not that simple. While Americans have no reason to be terrified to sit down at the dinner table, they have every reason to demand significant improvements in food and water safety. They unconsciously and unwillingly take in too much of too many dangerous chemicals. If food already contains natural carcinogens, it does not make much sense to add dozens of new man-made ones. Though most people will withstand the small amounts of contaminants generally found in food and water, at least a few individuals will probably get cancer one day because of what they eat and drink. To make good food and water supplies even better, the Government needs to tighten its regulatory standards, stiffen its inspection program and strengthen its enforcement policies. The food industry should modify some long-accepted practices or turn to less hazardous alternatives. Perhaps most important, consumers will have to do a better job of learning how to handle and cook food properly. The problems that need to be tackled exist all along the food-supply chain, from fields to processing plants to kitchens.

单选题 If the trade unionist Jimmy Hoffa were alive today, he would probably represent civil servant. When Hoffa's Teamsters were in their prime in 1960, only one in ten American government workers belonged to a union; now 36% do. In 2009 the number of unionists in America's public sector passed that of their fellow members in the private sector. In Britain, more than half of public-sector workers but only about 15% of private-sector ones are unionized. There are three reasons for the public-sector unions' thriving. First, they can shut things down without suffering much in the way of consequences. Second, they are mostly bright and well-educated. A quarter of America's public-sector workers have a university degree. Third, they now dominate left-of-centre politics. Some of their ties go back a long way. Britain's Labor Party, as its name implies, has long been associated with trade unionism. Its current leader, Ed Miliband, owes his position to votes from public-sector unions. At the state level their influence can be even more fearsome. Mark Baldassare of the Public Policy Institute of California points out that much of the state's budget is patrolled by unions. The teachers' unions keep an eye on schools, the CCPOA on prisons and a variety of labor groups on health care. In many rich countries average wages in the state sector are higher than in the private one. But the real gains come in benefits and work practices. Politicians have repeatedly "backloaded" public-sector pay deals, keeping the pay increases modest but adding to holidays and especially pensions that are already generous. Reform has been vigorously opposed, perhaps most egregiously in education, where charter schools, academies and merit pay all faced drawn-out battles. Even though there is plenty of evidence that the quality of the teachers is the most important variable, teachers' unions have fought against getting rid of bad ones and promoting good ones. As the cost to everyone else has become clearer, politicians have begun to clamp down. In Wisconsin the unions have rallied thousands of supporters against Scott Walker, the hardline Republican governor. But many within the public sector suffer under the current system, too. John Donahue at Harvard's Kennedy School points out that the norms of culture in Western civil services suit those who want to stay put but is bad for high achievers. The only American public-sector workers who earn well above $ 250,000 a year are university sports coaches and the president of the United States. Bankers' fat pay packets have attracted much criticism, but a public-sector system that does not reward high achievers may be a much bigger problem for America.

单选题If you intend using humor in your talk to make people smile, you must know how to identify shared experiences and problems. Your humor must be relevant to the audience and should help to show them that you are one of them or that you understand their situation and are in sympathy with their point of view. Depending on whom you are addressing, the problems will be different. If you are talking to a group of managers, you may refer to the disorganized methods of their secretaries; alternatively if you are addressing secretaries, you may want to comment on their disorganized bosses. Here is an example, which I heard at a nurses" convention, of a story which works well because the audience all shared the same view of doctors. A man arrives in heaven and is being shown around by St. Peter. He sees wonderful accommodations, beautiful gardens, sunny weather, and so on. Everyone is very peaceful, polite and friendly until, waiting in a line for lunch, the new arrival is suddenly pushed aside by a man in a white coat, who rushes to the head of the line, grabs his food and stomps over to a table by himself. "Who is that?" the new arrival asked St. Peter. "Oh, that"s God," came the reply, "but sometimes he thinks he"s a doctor. " If you are part of the group, which you are addressing, you will be in a position to know the experiences and problems which are common to all of you and it"ll be appropriate for you to make a passing remark about the inedible canteen food or the chairman"s notorious bad taste in ties. With other audiences you mustn"t attempt to cut in with humor as they will resent an outsider making disparaging remarks about their canteen or their chairman. You will be on safer ground if you stick to scapegoats like the Post Office or the telephone system. If you feel awkward being humorous, you must practice so that it becomes more natural. Include a few casual and apparently off-the-cuff remarks which you can deliver in a relaxed and unforced manner. Often it"s the delivery that causes the audience to smile, so speak slowly and remember that a raised eyebrow or an unbelieving look may help to show that you are making a light-hearted remark. Look for the humor. It often comes from the unexpected. A twist on a familiar quote "If at first you don"t succeed, give up" or a play on words or on a situation. Search for exaggeration and understatements. Look at your talk and pick out a few words or sentences which you can turn about and inject with humor.

单选题In recent years, railroads have been combining with each other, merging into supersystems, causing heightened concerns about monopoly. As recently as 1995, the top four railroads accounted for under 70 percent of the total ton-miles moved by rails. Next year, after a series of mergers is completed, just four railroads will control well over 90 percent of all the freight moved by major rail carriers. Supporters of the new supersystems argue that these mergers will allow for substantial cost reductions and better coordinated service. Any threat of monopoly, they argue, is removed by fierce competition from trucks. But many shippers complain that for heavy bulk commodities traveling long distances, such as coal, chemicals, and grain, trucking is too costly and the railroads therefore have them by the throat. The vast consolidation within the rail industry means that most shippers are served by only one rail company. Railroads typically charge such "captive" shippers 20 to 30 percent more than they do when another railroad is competing for the business. Shippers who feel they are being overcharged have the right to appeal to the federal government"s Surface Transportation Board for rate relief, but the process is expensive, time-consuming, and will work only in truly extreme cases. Railroads justify rate discrimination against captive shippers on the grounds that in the long run it reduces everyone"s cost. If railroads charged all customers the same average rate, they argue, shippers who have the option of switching to trucks or other forms of transportation would do so, leaving remaining customers to shoulder the cost of keeping up the line. It"s a theory to which many economists subscribe, but in practice it often leaves railroads in the position of determining which companies will flourish and which will fail. "Do we really want railroads to be the arbiters of who wins and who loses in the marketplace?" asks Martin Bercovici, a Washington lawyer who frequently represents shippers. Many captive shippers also worry they will soon be hit with a round of huge rate increases. The railroad industry as a whole, despite its brightening fortunes, still does not earn enough to cover the cost of the capital it must invest to keep up with its surging traffic. Yet railroads continue to borrow billions to acquire one another, with Wall Street cheering them on. Consider the $10.2 billion bid by Norfolk Southern and CSX to acquire Conrail this year. Conrail"s net railway operating income in 1996 was just $427 million, less than half of the carrying costs of the transaction. Who"s going to pay for the rest of the bill? Many captive shippers fear that they will, as Norfolk Southern and CSX increase their grip on the market.

单选题For years, French, Italian and American luxury brands have 1 as China"s middle class developed a(n) 2 for high-end fashion and jewelry. But that sales boom is 3 based on the disappointing results many Western luxury retailers have reported of late, 4 much suggests this slowdown will be 5 . French luxury brand Hermès said watch sales fell 11% in large 6() because of China, and the company is expecting overall growth this year to remain 6 compared to recent averages. Meanwhile, Prada said it expects the tough times for luxury to continue after its China sales fell 4% in 2014. 7 , Hermès, known for its highly coveted Birkin bags and horse-themed silk scarves that go for thousands of dollars each, has continued to 8 its stores in China. Why? Because there is 9 data to suggest that luxury"s current slowdown in China is 10 a speed bump. According to a new report by the Economic Intelligence Unit 11 by Citigroup, China"s wealthy will have double the 12 of their U.S counterpart within five years. That means a lot of people will be wanting to shop at Prada and Gucci and buying expensive Estée Lauder beauty products. And such companies are happy to 13 . Fashion company Michael Kors which is just getting started with its China expansion, recently said sales there are "starting to 14 ."

Tiffany is full 16 ahead with its China expansion 15 disappointing numbers over the holidays at its Hong Kong stores, a favorite haunt of mainland customers. So it"s clear that any Chinese slowdown is seen by luxury and retail executives as a temporary change. "China"s prestige beauty growth remains at high single digits, and we see 16 opportunities to enter additional cities, doors and 17 , and 18 more brands," Estée Lauder CEO said last month.

单选题Many of the tech industry"s biggest companies, like Amazon, Google, IBM and Microsoft, are jockeying to become the leader for artificial intelligence (A.I.). In the industry"s term, the companies are engaged in a "platform war." A platform, in technology, is essentially a piece of software that other companies build on and that consumers cannot do without. Become the platform and huge profits will follow. Microsoft dominated personal computers because its Windows software became the center of the consumer software world. Google has come to dominate the Internet through its ubiquitous search bar. If true believers in A.I. are correct that this long-promised technology is ready for the mainstream, the company that controls A.I. could steer the tech industry for years to come. "Whoever wins this race will dominate the next stage of the information age," said Pedro Domingos, a machine learning specialist and the author of "The Master Algorithm," a 2015 book that contends that A.I. and big-data technology will remake the world. In this fight—no doubt in its early stages—the big tech companies are engaged in tit-for-tat publicity stunts, circling the same start-ups that could provide the technology pieces they are missing and, perhaps most important, trying to hire the same brains. Fei-Fei Li, a Stanford University professor who is an expert in computer vision, said one of her Ph.D. candidates had an offer for a job paying more than $1 million a year, and that was only one of four from big and small companies. For years, tech companies have used man-versus-machine competitions to show they are making progress on A.I. In 1997, an IBM computer beat the chess champion Garry Kasparov. Five years ago, IBM went even further when its Watson system won a three-day match on the television trivia show "Jeopardy!" Today, Watson is the centerpiece of IBM"s A.I. efforts. By 2020, the market for machine learning applications will reach $40 billion, IDC, a market research firm, estimates. And 60 percent of those applications, the firm predicts, will run on the platform software of four companies—Amazon, Google, IBM and Microsoft. Intelligent software applications will become commonplace, said Jeff Dean, a computer scientist who oversees Google"s A.I. development. "And machine learning will touch every industry."

单选题As obvious as it may sound, the truth is there are a lot of businesses out there. The odds of not having any competition are next to impossible, and something any worthwhile business, whether big or small, has to eventually come to accept. Every one of those businesses are trying to do the exact same thing: get people to buy their products. When flooded with so many potential prospects it isn"t always easy for the customers to know which business is the best and which one has the best product. What you need to do is to help them along. Differentiating your business and your products from the competitors is by far one of the most important details when dealing With any kind of industry. Everything a company does, from the creative ads they run to the inventive promotions they produce to the full color business cards they hand out is geared towards separating themselves from the rest of the flock. If you"re going to compete with them you"re going to have to do the same, and do it more effectively. Sometimes the most effective approaches can be some of the most simple. Printing well-colored brochures gives businesses the chance to show their customers the subtle or not so subtle differences between them and the competitors, whether it is better designs, better features, or better prices. Handing them a list of all the products or services you offer allows them the ability to see exactly what they"re getting when they do business with you, and the more customers know about a business the better the odds are they"ll feel comfortable with them. But, even going beyond the products, boosting up your company can also be an effective tool to place you above the competitors. When you hand a person a business card, fully colored with a unique design you"re handing him a means to remember you. A business card can say a lot about a person and the business be run. Simple, drab colors can be off putting to the person looking for a friendlier business. The right color scheme alone can differentiate you from the competitors, and once you"ve managed to separate yourself out, you"ll be in a prime position to be whom the person favors when they need that specific product. With competition as steep as it is today, every business has its hands full trying to stay above the rest. When every little thing counts, the business the customers will take to heart will be the one who can show them just why they"re the best qualified. Printing out the right kind of colorful brochure or business card can be a valuable method of stepping away from the crowded business field.

单选题 Tens of thousands of 18-years-old will graduate this year and be handed meaningless diplomas. These diplomas won't look any different from those awarded their luckier classmates. Their validity will be questioned only when their employers discover that these graduates are semiliterate (半文盲). Eventually a fortunate few will find their way into educational-repair shops—adult-literacy programs, such as the one where I teach basic grammar and writing. There, high-school graduates and high-school dropouts pursuing graduate-equivalency certificates will learn the skills they should have learned in school. They will also discover they have been cheated by our educational system. I will never forget a teacher who got the attention of one of my children by revealing the trump card of failure. Our youngest, a world-class charmer, did little to develop his intellectual talents but always got by Until Mrs. Stifter. Our son was a high-school senior when he had her for English. "He sits in the back of the room talking to his friends," she told me. "why don't you move him to the front row?" I urged, believing the embarrassment would get him to settle down. Mrs. Stifter said, "I don't move seniors. I flunk (使……及格) them "Our son's academic life flashed before my eyes. No teacher had ever threatened him. By the time I got home I was feeling pretty good about this. It was a radical approach for these times, but, well, why not? "she's going to flunk you." I told my son. I did not discuss it any further. Suddenly English became a priority (头等要事) in his life. He finished out the semester with an A. I know one example doesn't make a case, but at night I see a parade of students who are angry for having been passed along until they could no longer ever pretend to keep up. Of average intelligence or better, they eventually quit school, concluding they were too dumb to finish. "I should have been held back," is a comment I hear frequently. Even sadder are those students who are high-school graduates who say to me after a few weeks of class, "I don't know how I ever got a high-school diploma." Passing students who have not mastered the work cheats them and employers who expect graduates to have basic skills. We excuse this dishonest behavior by saying kids can't learn if they come from terrible environments. No one seems to stop to think that most kids don't put school first on their list unless they perceive something is at risk. They'd rather be sailing. Many students I see at night have decided to make education a priority. They are motivated by the desire for a better job or the need to hang on to the one they've got. They have a healthy fear of failure. People of all ages can rise above their problems, but they need to have a reason to do so. Young people generally don't have the maturity to value education in the same way my adult students value it. But fear of failure can motivate both.

单选题"THE SERVANT" (1963) is one of those films that it is impossible to forget. The servant exploits his master"s weaknesses until he turns the tables: the story ends with the a cringing master ministering to a lordly servant. It is hard to watch it today without thinking of another awkward relationship—the one between businessfolk and their smartphones. Smart devices are sometimes empowering. They put a world of information at our fingertips. But for most people the servant has become the master. Not long ago only doctors were on call all the time. Now everybody is. Bosses think nothing of invading their employees" free time. Work invades the home far more than domestic chores invade the office. Hyperconnectivity exaggerates the decline of certainty and the general cult of flexibility. Smartphones make it easier for managers to change their minds at the last moment. Employees find it ever harder to distinguish between "on-time" and "off-time"—and indeed between real work and make-work. None of this is good for businesspeople"s marriages or mental health. It may be bad for business, too. When bosses change their minds at the last minute, it is hard to plan for the future. How can we reap the benefits of connectivity without becoming its slaves? One solution is digital dieting. Banning browsing before breakfast can reintroduce a small amount of civilization. Banning texting at weekends or, say, on Thursdays, can really show the iPhone who is boss. The problem with this approach is that it works only if you live on a desert island or at the bottom of a lake. Leslie Perlow of Harvard Business School argues that for most people the only way to break the 24/7 habit is to act collectively rather than individually. One of the world"s most hard-working organisations, the Boston Consulting Group, introduced rules about when people were expected to be offline, and encouraged them to work together to make this possible. Eventually it forced people to work more productively while reducing burnout. Ms Perlow"s advice should be taken seriously. The problem of hyperconnectivity will only get worse, as smartphones become smarter and young digital natives take over the workforce. But ultimately it is up to companies to outsmart the smartphones by insisting that everyone turn them off from time to time.

单选题Not too many decades ago it seemed "obvious" both to the general public and to sociologists that modern society has changed people"s natural relations, loosened their responsibilities to kin and neighbors, and substituted in their place superficial relationships with passing acquaintances. However, in recent years a growing body of research has revealed that the "obvious" is not true. It seems that if you are a city resident, you typically know a smaller proportion of your neighbors than you do if you are a resident of a smaller community. But, for the most part, this fact has few significant consequences. It does not necessarily follow that if you know few of your neighbors you will know no one else. Even in very large cities, people maintain close social ties within small, private social worlds. Indeed, the number and quality of meaningful relationships do not differ between more and less urban people. Small-town residents are more involved with kin than are big-city residents. Yet city dwellers compensate by developing friendships with people who share similar interests and activities. Urbanism may produce a different stifle of life, but the quality of life does not differ between town and city. Nor are residents of large communities any likelier to display psychological symptoms of stress or alienation, a feeling of not belonging, than are residents of smaller communities. However, city dwellers do worry more about crime, and this leads them to a distrust of strangers. These findings do not imply that urbanism makes little or no difference. If neighbors are strangers to one another, they are less likely to sweep the sidewalk of an elderly couple living next door or keep an eye out for young trouble makers. Moreover, as Wirth suggested, there may be a link between a community"s population size and its social heterogeneity. For instance, sociologists have found much evidence that the size of a community is associated with bad behavior including gambling, drugs, etc. Large-city urbanites are also more likely than their small-town counterparts to have a cosmopolitan outlook, to display less responsibility to traditional kinship roles, to vote for leftist political candidates, and to be tolerant of nontraditional religious groups, unpopular political groups, and so-called undesirables. Everything considered, heterogeneity and unusual behavior seem to be outcomes of large population size.

单选题What would make a smoker more likely to quit, a big reward for succeeding or a little penalty for failing? That is what researchers wanted to know when they assigned a large group of CVS employees (CVS Caremark is the country"s largest drugstore chain by sales), their relatives and friends to different smoking cessation programs. "Adding a bit of a stick was much better than a pure carrot. These large employers are spending an average of $800 to $900 per employee per year, but in ways that are often blind to normal human psychology" said Dr. Scott Halpern, who led the study. The trial was intended to change that . Researchers randomly assigned the participants to a number of program options and let them decide whether they wanted to participate. The penalty program required participants to deposit $150; six months later, those who had quit smoking would get the deposit back, along with a $650 reward. In the reward-only program, participants were simply offered an $800 payment if they stayed off cigarettes for six months. The trial, which was described in The New England Journal of Medicine on Wednesday, was the largest yet to test whether offering people financial incentives could lead to better health. Researchers found that offering incentives was far more effective in getting people to stop smoking than the traditional approach of giving free smoking cessation help, such as counseling or nicotine replacement therapy like gum, medication or patches. But they also found that requiring a $150 deposit that would be lost if the person failed to stay off cigarettes for six months nearly doubled the chances of success. "This is an original set of findings," said Cass R. Sunstein, a Harvard law professor who helped develop some influential ideas in the field of behavioral economics, notably that if the social environment can be changed—for example, by posting simple warnings—people can be nudged into better behavior. "They could be applied to many health issues, like alcoholism, or whenever people face serious self-control problems." Over all, success eluded most of the study participants. More than 80 percent of smokers in the most popular pure rewards group were still smoking at the end of the study. Even so, researchers say, their success rate was far greater than for those who got the traditional treatment. Smoking is the largest cause of preventable death in the United States. Diseases linked to it kill more than 480,000 Americans a year. And even a small decline could have a big health effect.

单选题The chances are that you made up your mind about smoking a long time ago and decided it"s not for you. The chances are equally good that you know a lot of smokers—there are, after all about 60 million of them—work with them, and get along with them very well. And finally it"s a pretty safe bet that you"re open-minded and interested in all the various issues about smokers and non-smokers—or you wouldn"t be reading this. And those three things make you incredibly important today. Because they mean that it"s your voice—not the smoker"s and not the anti-smoker"s—that will determine how much of society"s efforts should go into building walls that separate us and how much into the search for solutions that bring us together. For one tragic result of the emphasis on building walls is the diversion of millions of dollars from scientific research on the causes and cures of diseases which, when all is said and done, still strike the non-smoker as well as the smoker. One prominent health organization, to cite but a single instance, now spends 28 cents of every publicly contributed dollar on "education" (much of it in anti-smoking propaganda) and only 2 cents on research. There will always be some who want to build walls, who want to separate people from people, and up to a point, even these may serve society. The anti-smoking wall-builders have, to give them their due, helped to make us all more keenly aware of choice. But our guess, and certainly our hope, is that you are among the far greatest members who know that wails are only temporary at best, and that over the long run, we can serve society"s interest better by working together in mutual accommodation. Whatever virtue walls may have, they can never move our society toward fundamental solutions. People who work together on common problems, common solutions, can.

单选题The mythology of a culture can provide some vital insights into the beliefs and values of that culture. By using fantastic and sometimes incredible stories to create an oral tradition by which to explain the wonders of the natural world and teach lessons to younger generations, a society exposes those ideas and concepts held most important. Just as important as the final lesson to be gathered from the stories, however, are the characters and the roles they play in conveying that message. Perhaps the epitome of mythology and its use as a tool to pass on cultural values can be found in Aesop"s Fables, told and retold during the era of the Greek Empire. Aesop, a slave who won the favor of the court through his imaginative and descriptive tales, almost exclusively used animals to fill the roles in his short stories. Humans, when at all present, almost always played the part of bumbling fools struggling to learn the lesson being presented. This choice of characterization allows us to see that the Greeks placed wisdom on a level slightly beyond humans, implying that deep wisdom and understanding is a universal quality sought by, rather than steanning from, human beings. Aesop"s fables illustrated the central themes of humility and self-reliance, reflecting the importance of those traits in early Greek society. The folly of humans was used to contrast against the ultimate goal of attaining a higher level of understanding and awareness of truths about nature and humanity. For example, one notable fable features a fox repeatedly trying to reach a bunch of grapes on a very high vine. After failing at several attempts, the fox gives up, making up its mind that the grapes were probably sour anyway. The fable"s lesson, that we often play down that which we can"t achieve so as to make ourselves feel better, teaches the reader or listener in an entertaining way about one of the weaknesses of the human psyche. The mythology of Other cultures and societies reveal the underlying traits of their respective cultures just as Aesop"s fables did. The stories of Roman gods, Aztec ghosts and European elves all served to train ancient generations those lessons considered most important to their community, and today they offer a powerful looking glass by which to evaluate and consider the contextual environ ment in which those culture existed.

Aesop"s fables illustrated the central themes of humility and self-reliance, reflecting the importance of those traits in early Greek society. The folly of humans was used to contrast against the ultimate goal of attaining a higher level of understanding and awareness of truths about nature and humanity. For example, one notable fable features a fox repeatedly trying to reach a bunch of grapes on a very high vine. After failing at several attempts, the fox gives up, making up its mind that the grapes were probably sour anyway. The fable"s lesson, that we often play down that which we can"t achieve so as to make ourselves feel better, teaches the reader or listener in an entertaining way about one of the weaknesses of the human psyche. The mythology of other cultures and societies reveal the underlying traits of their respective cultures just as Aesop"s fables did. The stories of Roman gods, Aztec ghosts and European elves all served to train ancient generations those lessons considered most important to their community, and today they offer a powerful looking glass by which to evaluate and consider the contextual environment in which those culture existed.

单选题Anonymity is not something which was invented with the Internet. Anonymity and pseudonymity has occurred throughout history. For example, William Shakespeare is probably a pseudonym, and the real name of this 1 author is not known and will probably never be known. Anonymity has been used for many purposes. A well-known person may use a pseudonym to write messages, where the person does not want people"s 2 of the real author 3 their perception of the message. Also other people may want to 4 certain information about themselves in order to achieve a more 5 evaluation of their messages. A case in point is that in history it has been 6 that women used male pseudonyms, and for Jews to use pseudonyms in societies where their 7 was persecuted. Anonymity is often used to protect the 8 of people, for example when reporting results of a scientific study, when describing individual cases. Many countries even have laws which protect anonymity in certain circumstances. For instance, a person may, in many countries, consult a priest, doctor or lawyer and 9 personal information which is protected. In some 10 , for example confession in catholic churches, the confession booth is specially 11 to allow people to consult a priest, 12 seeing him face to face. The anonymity in 13 situations is however not always 100%. Ifa person tells a lawyer that he plans a 14 crime, some countries allow or even 15 that the lawyer tell the 16 . The decision to do so is not easy, since people who tell a priest or a psychologist that they plan a crime, may often do this to 17 their feeling more than their real intention. Many countries have laws protecting the anonymity of tip-offs to newspapers. It is regarded as 18 that people can give tips to newspapers about abuse, even though they are dependent 19 the organization they are criticizing and do not dare reveal their real name. Advertisement in personal sections in newspapers are also always signed by a pseudonym for 20 reasons.

单选题"Is it a vital interest of the state to have more anthropologists?" Rick Scott, the Florida governor, once asked. A leader of a prominent Internet company once told me that the firm regards admission to Harvard as a useful proof of talent, but a college education itself as useless. Parents and students themselves are acting on these principles, retreating from the humanities. I"ve been thinking about this after reading Fareed Zakaria"s smart new book, In Defense of a Liberal Education . Like Mr. Zakaria, I think that the liberal arts teach critical thinking. So, to answer the skeptics, here are my three reasons the humanities enrich our souls and sometimes even our pocketbooks as well. First, liberal arts equip students with communications and interpersonal skills that are valuable and genuinely rewarded in the labour force, especially when accompanied by technical abilities. "A broad liberal arts education is a key pathway to success in the 21st-century economy," says Lawrence Katz, a labour economist at Harvard. Professor Katz says that the economic return to pure technical skills has flattened, and the highest return now goes to those who combine soft skills— excellence at communicating and working with people—with technical skills. My second reason: We need people conversant with the humanities to help reach wise public policy decisions, even about the sciences. Technology companies must constantly weigh ethical decisions. To weigh these issues, regulators should be informed by first-rate science, but also by first-rate humanism. When the President"s Council on Bioethics issued its report in 2002, "Human Cloning and Human Dignity," it depends upon the humanities to shape judgments about ethics, limits and values. Third, wherever our careers lie, much of our happiness depends upon our interactions with those around us, and there"s some evidence that literature nurtures a richer emotional intelligence. Science magazine published five studies indicating that research subjects who read literary fiction did better at assessing the feelings of a person in a photo than those who read nonfiction or popular fiction. Literature seems to offer lessons in human nature that help us decode the world around us and be better friends. Literature also builds bridges of understanding. In short, it makes eminent sense to study coding and statistics today, but also history and literature.

单选题Picture a typical MBA lecture theatre twenty years ago. In it the majority of students will have conformed to the standard model of the time: male, middle class and Western. Walk into a class today, however, and you'll get a completely different impression. For a start, you will now see plenty more women-the University of Pennsylvania's Wharton School, for example, boasts that 40% of its new enrolment is female. You will also see a wide range of ethnic groups and nationals of practically every country. It might be tempting, therefore, to think that the old barriers have been broken down and equal opportunity achieved. But, increasingly, this apparent diversity is becoming a mask for a new type of conformity. Behind the differences in sex, skin tones and mother tongues, there are common attitudes, expectations and ambitions which risk creating a set of clones among the business leaders of the future. Diversity, it seems, has not helped to address fundamental weaknesses in business leadership. So what can be done to create more effective managers of the commercial world? According to Valerie Gauthier, associate dean at HEC Paris, the key lies in the process by which MBA programmes recruit their students. At the moment candidates are selected on a fairly narrow set of criteria such as prior academic and career performance, and analytical and problem solving abilities. This is then coupled to a school's picture of what a diverse class should look like, with the result that passport, ethnic origin and sex can all become influencing factors. But schools rarely dig down to find out what really makes an applicant succeed, to create a class which also contains diversity of attitude and approach-arguably the only diversity that, in a business context, really matters. Professor Gauthier believes schools should not just be selecting candidates from traditional sectors such as banking, consultancy and industry. They should also be seeking individuals who have backgrounds in areas such as political science, the creative arts, history or philosophy, which will allow them to put business decisions into a wider context. Indeed, there does seem to be a demand for the more rounded leaders such diversity might create. A study by Mannaz, a leadership development company, suggests that, while the bully-boy chief executive of old may not have been eradicated completely, there is a definite shift in emphasis towards less tough styles of management- at least in America and Europe. Perhaps most significant, according to Mannaz, is the increasing interest large companies have in more collaborative management models, such as those prevalent in Scandinavia, which seek to integrate the hard and soft aspects of leadership and encourage delegated responsibility and accountability.

单选题Cigarette smoking is a health hazard of sufficient importance in the United States. It was 50 years ago this month that America"s Surgeon General sounded that warning, marking the beginning of the end of cigarette manufacturing—and of smoking itself—as a respectable activity. Some 20 million Americans have died from the habit since then. But advertising restrictions and smoking bans have had their effect: the proportion of American adults who smoke has dropped from 43% to 18%; smoking rates among teenagers are at a record low. In many other countries the trends are similar. The current Surgeon General, Boris Lushniak, marked the half-century with a report on January 17th, declaring smoking even deadlier than previously thought. He added diabetes, colorectal cancer and other ailments to the list of ills it causes, and promised end-game strategies to extinguish cigarettes altogether. New technologies such as e-cigarettes promise to deliver nicotine less riskily. E-cigarettes give users a hit of vapour infused with nicotine. In America, sales of the manufacturer, who is the fastest e-cigarettes-adopter, have jumped from nearly nothing five years ago to at least 1 billion in 2013. At first, it looked as if e-cigarettes might lure smokers from the big tobacco brands to startups such as NJOY. But tobacco companies have bigger war chests , more knowledge of smokers" habits and better ties to distributors than the newcomers. Some experts reckon Americans will puff more e-cigarettes than normal ones within a decade, but tobacco folk are skeptical. E-cigarettes account for just 1% of America"s cigarette market. In Europe 7% of smokers had tried e-cigarettes by 2012 but only 1% kept them up. And no one knows what sort of restrictions regulators will eventually place on reduced risk products, including e-cigarettes. If these companies can manage the transition to less harmful smokes, and convince regulators to be sensible, the tobacco giants could keep up the sort of performance that has made their shares such a fine investment over the years. But some analysts are not so sure. Many tobacco firms are struggling to deliver the consistency of the earnings-per-share model we"ve seen in the past. If that persists, investors may fall out of love with the industry. A half-century after the Surgeon General"s alarm, they, and hopeless smokers, are its last remaining friends.
