单选题The book which had a great influence on sociology was written ______.

单选题In 1924 America"s National Research Council sent two engineers to supervise a series of industrial experiments at a large telephone-parts factory called the Hawthorne Plant near Chicago. It hoped they would learn how shop-floor lighting 21 workers" productivity. Instead, the studies ended 22 giving their name to the "Hawthorne effect", the extremely influential idea that the very 23 to being experimented upon changed subjects" behavior. The idea arose because of the 24 behavior of the women in the Hawthorne plant. According to 25 of the experiments, their hourly output rose when lighting was increased, but also when it was dimmed. It did not 26 what was done in the experiment; 27 something was changed, productivity rose. A(n) 28 that they were being experimented upon seemed to be 29 to alter workers" behavior 30 itself. After several decades, the same data were 31 to econometric analysis. Hawthorne experiments had another surprise in store. 32 the descriptions on record, no systematic 33 was found that levels of productivity were related to changes in lighting. It turns out that peculiar way of conducting the experiments may be have let to 34 interpretation of what happed. 35 , lighting was always changed on a Sunday. When work started again on Monday, output 36 rose compared with the previous Saturday and 37 to rise for the next couple of days. 38 , a comparison with data for weeks when there was no experimentation showed that output always went up on Monday, workers 39 to be diligent for the first few days of the week in any case, before 40 a plateau and then slackening off. This suggests that the alleged "Hawthorne effect" is hard to pin down.

单选题When it comes to the slowing economy, Ellen Spero isn"t biting her nails just yet. But the 47-year-old manicurist isn"t cutting, filing or polishing as many nails as she"d like to, either. Most of her clients spend $12 to $ 50 weekly, but last month two longtime customers suddenly stopped showing up. Spero blames the softening economy. "I"m a good economic indicator," she says. "I provide a service that people can do without when they"re concerned about saving some dollars." So Spero is downscaling, shopping at middle-brow Dillard"s department store near her suburban Cleveland home, instead of Neiman Marcus. "I don"t know if other clients are going to abandon me, too," she says. Even before Alan Greenspan"s admission that America"s red-hot economy is cooling, lots of working folks had already seen signs of the slowdown themselves. From car dealerships to Gap outlets, sales have been lagging for months as shoppers temper their spending. For retailers, who last year took in 24 percent of their revenue between Thanksgiving and Christmas, the cautious approach is coming at a crucial time. Already, experts say, holiday sales are off 7 percent from last year"s pace. But don"t sound any alarms just yet. Consumers seem only mildly concerned, not panicked, and many say they remain optimistic about the economy"s long-term prospects even as they do some modest belt-tightening. Consumers say they"re not in despair because, despite the dreadful headlines, their own fortunes still feel pretty good. Home prices are holding steady in most regions. In Manhattan, "There"s a new gold rush happening in the $4 million to $10 million range, predominantly fed by Wall Street bonuses," says broker Barbara Corcoran. In San Francisco, prices are still rising even as frenzied overbidding quiets. "Instead of 20 to 30 offers, now maybe you only get two or three," says John Tealdi, a Bay Area real-estate broker. And most folks still feel pretty comfortable about their ability to find and keep a job. Many folks see silver linings to this slowdown. Potential home buyers would cheer for lower interest rates. Employers wouldn"t mind a little fewer bubbles in the job market. Many consumers seem to have been influenced by stock-market swings, which investors now view as a necessary ingredient to a sustained boom. Diners might see an upside, too. Getting a table at Manhattan"s hot new Alain Ducasse restaurant used to be impossible. Not anymore. For that, Greenspan & Co. may still be worth toasting.

单选题Imagine a Briton"s new year resolutions: he vows to stop smoking 20 cigarettes a day, and abandon his daily bottle of claret and nightly whisky. Confronting his enlarging gut, he may even promise to make his ten-mile round-trip commute by bike, not car. What admirable goals. And since this gentleman"s annual vice bill comes to around 7,500 pounds, he will be well-rewarded for his virtue even before considering the effect on his health. But the Treasury might rejoice a little less. In the fiscal year 2010-11 nearly 10% of all taxes collected came from duty on alcohol, tobacco, and fuel as well as from vehicle excise duty, a tax that falls most heavily on the least efficient cars. You may say that New Year resolutions are notoriously short-lived, but the longer-run trend still looks bad for the exchequer. Because many vices are in constant decline, so are receipts, predicts the Office for Budget Responsibility (OBR). Smoking rates have been falling for decades, attributed partly to high taxes, and partly to public health campaigns changing social mores and a smoking ban in workplaces introduced across Britain in 2007. The government could respond by increasing sin tax rates. But when duties rise, so do the incentives to get around them, by buying abroad or on the black market. This is particularly common with cigarettes, which are easy for individual smokers to import. In 2000 non-duty consumption reached a peak of 78%, a consequence of the weak euro as well as a sudden increase in taxes of inflation plus 5%. Petrol taxes are leaking more quickly. As with smoking, behavior is changing: car and van mileage has fallen for four consecutive years, partly because petrol is so expensive and new vehicles have better engines. These trends, as well as the rise of electric and hybrid cars, are forecast to compress receipts from 1.8% of GDP in 2010 to just 1.1% in 2030. There are, of course, advantages to Britons giving up their filthy habits. Smoking is the leading cause of preventable illness and premature death in Britain. It cost the National Health Service more than 5 billion pounds a year in 2005-06, some 5.5% of its budget at the time, according to an Oxford University study. But any benefit to the NHS may be short-lived. Those who do not perish from diseases associated with smoking are likely to die more slowly of age-related illnesses. In moral terms, a decline in sin tax receipts suggests a job well done. But in fiscal terms, a hole is a hole. As the OBR sees it, falling Treasury income means Britons will be getting, in effect, an unannounced tax cut. Other taxes could therefore rise without leaving people worse off in aggregate. The maths makes sense. For the virtuous, though, being clobbered with new taxes may seem a rather poor reward.

单选题Coconut (椰子) is an unusual food for many reasons. It is one of the largest edible seeds produced by any plant. Its unusual contents also make it unique in the seed world—it consists of both "meat" and "water" inside. The coconut meat is the white substance with which we are all familiar, as it is used extensively for cooking and flavorings; the coconut water is a white and sweet liquid. Portuguese (葡萄牙的) explorers gave the nut its name in the 15th century, referring to it as coco, meaning "ghost" in their language. The outside appearance of coconuts reminded them of a ghost"s face, and the tree has had that name ever since. The coconut has varied uses. It is used to make various cooking oils for fast-food restaurants around the world to make diet materials. The coconut fluid is a favorite drink in hot climates, providing a cool and refreshing beverage right off the tree. This water is also used by manufacturers of various sports drinks. Even the shell itself has many uses, including animal food and fertilizer. Yet the coconut is also useful in many ways that have nothing to do with food. Coconut oil is used for cosmetics (化妆品), medicines, and so on. Dried coconut shells are used in many countries as a tool for shining wood floors. The shells are also used for shirt buttons, and are commonly found on Hawaiian clothing. They are even used for musical instruments and bird houses. And all these are only some of the uses found for the coconut fruit. The coconut tree, which produces the nut, also produces many useful things. It"s no wonder that the coconut tree has been taken as "the tree of life".

单选题There are some people who will always______a cause merely because others are attacking or criticizing it.

单选题The traffic lights were red when the driver reached them. To the surprise of his passenger, the car did not slow down. Unexpectedly the passenger was thrown forward in the vehicle as the driver put on his brakes at the last moment. The car stopped just in time. "Sorry, I didn’t notice the light. I thought it was green until I saw that it was the top light which was shining." This strange story is quite tree. About ten men in every hundred are color blind in some way, women are luckier — only about one in two hundred suffers from color blindness. In some cases, a man may not be able to see deep red. He may think that red, orange and yellow are all the same as green. People often like one color more than others. Blue is the color of the sky and sea. Careen makes us think of fields and trees. Red is the color of blood and makes some people think of danger. Black is the color of night. In the dark we cannot see what is around us so we are sometimes afraid of the unknown and do not like black as a color.
