单选题LAST month, America's National Law Journal told its readers that "employment lawyers are warning lovestruck co-workers to take precautions in the office before locking lips outside". The advice came too late for Harry Stonecipher. The boss of Boeing was forced to resign last weekend—for reasons that will strike many outsiders as absurd—after his board were told of an affair that the 68-year-old married man had been conducting with a female employee "who did not report directly to him". Inevitably, as the week rolled on, details of the affair rolled out. The other party was reported to be Debra Peabody, who is unmarried and has worked for Boeing for 25 years. The couple were said to have first got together at Boeing's annual retreat at Palm Desert, California in January. After that much of the affair must have been conducted from a distance: Mr. Stonecipher's office is at Boeing's headquarters in Chicago; Ms Peabody runs the firm's government-relations office in Washington, DC. They exchanged e-mails, it seems, as office lovers tend to do these days, and therein probably lay Mr Stonecipher's downfall. Lewis Platt, Boeing's chairman, said that Mr Stonecipher broke a company rule that says: "Employees will not engage in conduct or activity that may raise questions as to the company's honesty, impartiality, reputation or otherwise cause embarrassment to the company." Having an affair with a fellow employee is not, of itself, against company rules; causing embarrassment to Boeing is. It seems that the board judged that the contents of the lovers' e-mails would have been bad for Boeing had they been made public. Gone are the days when a board considered such matters none of its business, as Citibank's did in 1991 when its boss, John Reed, became the talk of Wall Street for having an affair with a stewardess on Citi's corporate jet. At Boeing, a whistleblower is said to have forwarded the messages to Mr Platt. In general, e-mails are encrypted and not accessible to anyone who does not know the sender's password. But many firms install software designed to search electronic communications for key words such as, "sex" and "CEO". A study last year of 840 American firms by the American Management Association found that 60% of them check external e-mails (incoming and outgoing), while 27% scrutinize internal messages between employees. Sweet nothings whispered by the water cooler may travel less far these days than electronic billets doux. Boeing is particularly sensitive to embarrassment at the moment. Mr. Stonecipher was recalled from retirement only 15 months ago, after the company's previous boss, Phil Condit, and its chief financial officer, Michael Sears, had left in the wake of a scandal involving an illegal job offer to a Pentagon official. Mr Stonecipher, a crusty former number two at Boeing, was brought back specifically to raise the company's ethical standards and to help it be seen in its main (and affectedly puritanical) market, in Washington, DC, as squeaky clean. Verbally explicit extra-marital affairs are inconsistent with such a strategy, it seems, though they are not yet enough to bring down future kings of England. In corporate life, such affairs are hardly unusual. One survey found that one-quarter of all long-term relationships start at work; another found that over 40% of executives say they have been involved in an affair with a colleague, and that in half of these cases one or other party was married at the time. Many a boss has married his assistant and lived happily ever after. Boeing apparently used to accept this: Mr. Condit's fourth wife was a colleague before they married.

单选题A proven method for effective textbook reading is the SQ3R method developed by Francis Robinson. The first step is to survey (the S step) the chapter by reading the title, introduction, section headings, summary and by studying any graphs, tables, illustrations or charts. The purpose of this step is to get an overview of the chapter so that you will know before you read what it will be about. In the second step (the Q step), for each section you ask yourself questions such as "What do I already know about this topic?" and "What do I want to know?" In this step you also take the section heading and turn it into a question. This step gives you a purpose for reading the section. The third step (the first of the 3 R's) is to read to find the answer to your questions. Then at the end of each section, before going on to the next section, you recite (the second of the 3 R's) the answers to the questions that you formed in the question step. When you recite you should say the information you want to learn out loud in your own words. The fifth step is done after you have completed steps 2, 3 and 4 for each section. You review (the last of the 3 R's) the entire chapter. The review is done much as the survey was in the first step. As you review, hold a mental conversation with yourself as you recite the information you selected as important to learn. The mental conversation could take the form of asking and answering the questions fromed from the headings or reading the summary, which lists the main ideas in the chapter, and trying to fill in the details for each main idea.

单选题Because of its potential for cutting costs, the distribution step in the marketing process is receiving more attention. Distribution involves warehousing, transporting and keeping inventory of manufactured products. Take an everyday product like fabric softener. After it comes off the assembly line, it's packed in cartons and trucked to warehouses around the country. When orders come in from retailers, the fabric softener is delivered to supermarket shelves. This is distribution. Probably the most crucial area for controlling costs is inventory. Companies don't want to overproduce and have unsold stock of their product piled up in warehouses. Wholesale companies and large retail chains employ several techniques for inventory control. This is where the computer revolution really had an impact. Computerized information systems give precise and up-to-date accounts of inventory on hand. And the field of distribution offers good entry-level jobs for persons with training in computer programming or data processing. Overseeing the whole area of distribution is the distribution manager. This job is becoming increasingly important and can lead to an executive position.

单选题{{B}}Text 4{{/B}} You cannot buy Prada shoes on Prada. com. In fact, there are no working links on the Web site. This is not a technical disorder. Since the late' 9Os, the site has been a single page, with only the name of the Italian fashion house and two photographs. No store locations or help numbers. Nothing. "I love Prada," ponders Nina Dietzel, president of Web-design company 300FeetOut. "But what's up with their 'site' ?" Prada claims a new Web site is "under development." But having a mysteriously useless home page, it admits, has an allure. It screams exclusivity: you can see, but you can't click. It's a uniquely Prada solution to this riddle: how to make your luxury brand work on the Internet without diminishing its value. In a sense, the Internet is antithetical to the "high touch" luxury experience. There is no indulgence by sales staff, and customers have come to see the Net as a path to cheap prices, not top-dollar goods. There's no velvet rope: anyone can place an order, or set up shop. That's why Prada strives to maintain the link between its name and the extravagant experience of shopping at stores like its $ 40 million New York flagship, designed by Rem Koolhaas. Unlike Prada, most luxury companies can't afford to ignore the Web: in the United States, ecommerce accounted for $ 2.5 billion in luxury sales. That figure is expected to grow to $ 7 billion by 2010, says Forrester Research. It's still a small fraction of the total market compared to other retail sectors, but five years ago analysts said there was "no way" luxury would sell online. They were betting customers wouldn't pay that much on the Web, and top brands wouldn't go slumming in this bargain basement. One of the first high-end luxury retailers, Ashford. com, had many well-publicized struggles, with its stock dropping to near rock bottom in 2001. Companies like Neiman Marcus that have strong catalog sales have made the transition to the Web more easily; online sales are the company's fastest-growing source of revenue. Swiss watchmakers Breitling and Patek Philippe have taken another tack with Web sites that offer only information, not sales. Breitling director of marketing Ben Balmer says a luxury brand needs to offer "a buying experience" that only a well-run store can provide. However, he notes that since 2002, it has presented 30 percent fewer catalogs in the United States, and seen sales rise more than 35 percent, thanks to exposure on the Internet. Prada may not need a working Web site after all.

单选题If the Europeans thought a drought—a long period of dry weather—was something that happened only in Africa, they know better now. After four years of below-normal rainfall (in some cases only 10 percent of the annual average), vast areas of France, Spain, Portugal, Belgium, Britain and Ireland are dry and barren(贫瘠). Water is so low in the canals of northern France that waterway traffic is forbidden except on weekends. Oyster (牡蛎) grows in Brittany report a 30 percent drop in production because of the loss of fresh water in local rivers necessary for oyster breeding. In southeastern England, the rolling green hills of Kent have turned so brown that officials have been weighing plans to pipe in water from Wales. In Portugal, farmers in the southern Alentejo region have held prayer meeting for rain—so far, in vain. Governments in drought-spread countries are taking severe measures. Authorities in hard-hit areas of France have banned washing cars and watering lawns. In Britain, water will soon be metered, like gas and electricity. "The English have always taken water for granted," says Graham Warren, a spokesman of Britain"s National Rivers Authority. "Now they"re putting a price on it." Even a sudden end to the drought would not end the misery in some areas. It will take several years of unusually heavy winter rain, the experts say, just to bring existing water reserves up to their normal levels.

单选题Time, as we know it, is a very recent invention. The modern time-sense is hardly older than the United States. It is a by-product of industrialism--a sort of psychological analogue of synthetic perfumes and aniline dyes. Time is our tyrant. We are chronically aware of the moving minute hand, even of the moving second hand. We have to be. There are trains to be caught, clocks to be punched, tasks to be done in specified periods, records to be broken by fractions of a second, machines that set the pace and have to be kept up with. Another time-emphasizing entity is the factory and its dependent, the office. Factories exist for the purpose of getting certain quantities of goods made in a certain time. The old artisan worked as it suited him with the result that consumers generally had to wait for the goods they had ordered from him. The factory is a device for making workmen hurry. The machine revolves so often each minute; so many movements have to be made, so many pieces produced each hour. Result: the factory worker (and the same is true of the office worker) is compelled to know time in its smallest fractions. In the hand-work age there was no such compulsion to be aware of minutes and seconds. Our awareness of time has reached such a pitch of intensity that we suffer acutely whenever our travels take us into some corner of the world where people are not interested in minutes and seconds. The unpunctuality of the Orient, for example, is appalling to those who come freshly from a land of fixed meal-times and regular train services. For a modern American or Englishman, waiting is a psychological torture. An Indian accepts the blank hours with resignation, even with satisfaction. He has not lost the fine art of doing nothing. Our notion of time as a collection of minutes, each of which must be filled with some business or amusement, is wholly alien to the Oriental, just as it was wholly alien to the Greek. For the man who lives in a pre-industrial world, time moves at a slow and easy pace; he does not care about each minute, for the good reason that he has not been made conscious of the existence of minutes. This brings us to a seeming paradox. Acutely aware of the smallest constituent particles of time--of time, as measured by clock-work and train arrivals and the revolutions of machines--industrialized man has to a great extent lost the old awareness of time in its larger divisions. The time of which we have knowledge is artificial, machine-made time. Of natural, cosmic time, as it is measured out by sun and moon, we are for the most part almost wholly unconscious. Pre-industrial people know time in its daily, monthly and seasonal rhythms. They are aware of sunrise, noon and sunset; of the full moon and the new; of equinox and solstice; of spring and summer, autumn and winter. Industrialism and urbanism have changed all this. One can live and work in a town without being aware of the daily march of the sun across the sky; without ever seeing the moon and stars. Even changes of season affect the townsman very little. He is the inhabitant of an artificial universe that is, to a great extent, walled off from the world of nature. Outside the walls, time is cosmic and moves with the motion of sun and stars. Within, it is an affair of revolving wheels and is measured in seconds and minutes--at its longest, in eight-hour days and five-day weeks. We have a new consciousness; but it has been purchased at the expense of the old consciousness.
