单选题 In 1930, W. K. Kellogg made what he thought was a sensible decision, grounded in the best economic, social and management theories of the time. Workers at his cereal plant in Battle Greek, Mich. were told to go home two hours earlier, every day for good. The Depression-era move was hailed in {{I}}Factory and Industrial Management{{/I}} magazine as the "biggest piece of industrial news since Henry Ford announced his five-dollar-a-day policy." It's believed that industry and machines would lead to workers' paradises where all would have less work, more free time, and yet still produce enough to meet their needs. So what happened? Today, instead of working less, our hours have stayed steady or risen- and today many more women work so that families can afford the trappings of suburbia. In effect, workers chose the path of consumption over leisure. With unemployment at a nine-year high and many workers worded about losing their jobs- or forced to accept cutbacks in pay and benefits -- work is hardly the paradise economists once envisioned. The modern environment would seem alien to pre-industrial laborers. For centuries, the household -- from farms to "cottage" craftsmen -- was the unit of production. The whole family was part of the enterprise, be it farming, blacksmithing, or baking. "In pre-industrial society, work and family were practically the same thing," says Gillis. The Industrial Revolution changed all that. Mills and massive iron smelters required ample labor and constant attendance. For the first time, work and family were split. Instead of selling what they produced, workers sold their time. With more people leaving farms to move to cities and factories, labor became a commodity and placed on the market like any other. Innovation gave rise to an industrial process based on machinery and mass production. The theories of Frederick Taylor, a Philadelphia factory foreman, led to work being broken down into component parts, with each step timed to coldly quantify jobs that skilled craftsmen had worked a lifetime to learn. Workers resented Taylor and his stopwatch, complaining that his focus on process stripped their jobs of creativity and pride, making them irritable. Long before anyone knew what "stress" was, Taylor brought it to the workplace- and without sympathy. The division of work into components that could be measured and easily taught reached its apex in Ford's River Rouge Plant in Dearborn, Mich., where the assembly line {{U}}came of age{{/U}}. To maximize the production lines, businesses needed long hours from their workers. But it was no easy to sell. Labor leaders fought back with their own propaganda. For more than a century, a key struggle for the labor movement was reducing the amount of time workers had to spend on the job. Between 1830 and 1930, work hours were cut nearly in half, with economist John Maynard Keynes famously predicting in 1930 that by 2030 a 15-hour workweek would be standard. While work had once been a means to serve God, two centuries of choices and industrialization had turned work into an end in itself, stripped of the spiritual meaning that sustained the Puritans who came ready to tame the wilderness. By the end of the 1970s, companies were reaching out to spiritually drained workers by offering more engagement while withdrawing the promise of a job for life, as the American economy faced a stiff challenge from cheaper workers abroad. By the 1990s, technology made working from home possible for a growing number of people. Seen as a boon at first, telecommuting and the rapidly proliferating "electronic leash" of cell phones made work inescapable, as employees found themselves on call 24/7. Today, almost half of American workers use computers, cell phones, E-mail, and faxes for work during what is supposed to be nonwork time. Home is no longer a refuge but a cozier extension of the office. When the stock market bubble burst and the economy fell into its recent recession, workers were forced to re-evaluate their priorities. They want a better quality of life; they're asking for more flextime to spend with their families. But there's still the question of fulfillment. A recent study shows that work doesn't satisfy workers' deeper needs. "We expect more and more out of our jobs," says Hunnicutt. "We expect to find wonderful people and experience all around us."

单选题 Ever since it was claimed that a medicine made from the Chinese three-striped box turtle could cure cancer, demand for the product has increased, making the turtle the most expensive to be found in China's food markets. Huge sums of money have been made selling {{U}}the medicine{{/U}}. The turtle -- along with a few other Cuora species -- was once imported into China by the pet trade. Exporters obtained the specimens in the food markets rather than going out to collect them in the wild. Treatment of the turtles prior to reaching the markets resulted in many of them being diseased. Packed tightly into crates, often for journeys of several weeks without food, it is little wonder that many specimens exported to western countries fared poorly when purchased as pets. Throughout the Far East turtles and tortoises have featured in various cultures and certain religions. They have also been used for hundreds of years for food and medicine. Traditional Chinese medicine is probably the greatest threat to the three-striped box and to the thousands of other turtles that are imported yearly into China. Turtles are well known for their longevity, which it is thought will be passed on to those eating them. Turtle blood, bones and shells -- particularly the plastron (ventral part of the shell) -- are thought to have medicinal properties and be able to cure a number of ailments. Turtle eggs are also used for food and medicine. The medicinal value of the turtles is open to question, and it is possible that herbs could produce the same effects. Any beneficial substances from the turtles could also be synthesized chemically, so as to prevent the killing of turtles. The southern part of China has become more prosperous in recent years, and the demand for turtles has increased dramatically. Turtle dishes are served in restaurants and regarded as an expensive delicacy, even a status symbol. As turtle supplies in China dwindled, traders started importing the animals from Vietnam. As a result, many Vietnamese turtles have now disappeared from their haunts in the wild. To satisfy growing demand, importers have now turned to sources farther afield, including Cambodia, Laos, Nepal, India, Bhutan and Indonesia. Since biologists started studying turtles in Chinese food markets, several previously unknown and extremely rare species have been found; some are on Appendix I of CITES. At the present rate of collection such specimens, and even species not yet discovered, could soon be extinct. The three-striped box turtle is simply one among dozens of other species flooding into China, but its high value makes it a special target for collectors.
