单选题George Bernard Shaw once wrote: "There is no love sincerer than the love of food. "That love has limits, however. In thin years, diners value their wallets over their palates. Visits to posh restaurants in America declined by 15 % between May 2008 and May this year, according to the NPD Group, a research firm. Fast-food restaurants, on the other hand, saw traffic decline only 2%. To lure eaters back, many fine restaurants have done what luxury brands hate to do: have a cut-price sale. Some offer discounts to those who dine at unpopular times, such as early in the evening or on Sunday. Restaurant Week, a twice-yearly tradition in New York City where restaurants offer discounted prix-fixed menus at lunch and dinner, was extended by six weeks this summer. This may help. The 21 Club, a fancy joint in Manhattan, usually sees its business increase by around 25%～40% during Restaurant Week, says Bryan McGuire, its general manager. Many restaurants have also turned to the Internet. Gilt and Rue La La, two popular online shopping sites that offer heavy discounts on designer clothing, have started to peddle meals at fancy restaurants too. Gilt, for example, recently sold a four-course meal at the Tribeca Grill, a restaurant owned by Robert De Niro, an actor, for $160 (36% off). Shopping sites like these attract image-conscious restaurants, because only the site's members can see that the restaurant has started to offer leaner prices. Another website, Groupon, has gained popularity among restaurants as a way to bring in new customers. The company offers a daily discount in each of the 140 American and European cities where it operates. Some 40% of its promotions are for restaurants. The deals can be generous: some offer $50-worth of food and wine for $25. The deal only goes into effect, however, if enough people buy it. So people prod their Facebook friends to join the feeding frenzy. This type of "collective buying" has caught on. Since the firm started in 2008, it has brokered the sale of more than 8.8m "groupons" and saved customers around $375m. La Condesa, a restaurant in Austin, has sold 3,000 groupons. " It brings a lot of people into the restaurant who would never have come in," says Jesse Herman, an executive. Tasty offerings abound online. OpenTable, a website, allows people to book a table without having to plead with a snooty hostess. It also makes it easier for restaurants to track customers. SeamlessWeb allows people in America and Britain to search online for nearby eateries and order their food delivered. Even swanky restaurants have started to take part, betting that some people might want to eat haute cuisine without dressing for the occasion. But SeamlessWeb takes a cut of restaurants' sales for bringing them business, so restaurants have to decide whether' it's better to stay hungry for customers or share part of their meal with someone else.

单选题It"s no surprise that Jennifer Senior"s insightful, provocative magazine cover story, "I love My Children, I Hate My Life," is arousing much chatter—nothing gets people talking like the suggestion that child rearing is anything less than a completely fulfilling, life-enriching experience. Rather than concluding that children make parents either happy or miserable, Senior suggests we need to redefine happiness: instead of thinking of it as something that can be measured by moment-to-moment joy, we should consider being happy as a past-tense condition. Even though the day-to-day experience of raising kids can be soul-crushingly hard, Senior writes that "the very things that in the moment dampen our moods can later be sources of intense gratification and delight." The magazine cover showing an attractive mother holding a cute baby is hardly the only Madonna-and-child image on newsstands this week. There are also stories about newly adoptive—and newly single—mom Sandra Bullock, as well as the usual "Jennifer Aniston is pregnant" news. Practically every week features at least one celebrity morn, or mom-to-be, smiling on the newsstands. In a society that so persistently celebrates procreation, is it any wonder that admitting you regret having children is equivalent to admitting you support kitten-killing? It doesn"t seem quite fair, then, to compare the regrets of parents to the regrets of the childless. Unhappy parents rarely are provoked to wonder if they shouldn"t have had kids, but unhappy childless folks are bothered with the message that children are the single most important thing in the world: obviously their misery must be a direct result of the gaping baby-size holes in their lives. Of course, the image of parenthood that celebrity magazines like Us Weekly and People present is hugely unrealistic, especially when the parents are single mothers like Bullock. According to several studies concluding that parents are less happy than childless couples, single parents are the least happy of all. No shock there, considering how much work it is to raise a kid without a partner to lean on; yet to hear Sandra and Britney tell it, raising a kid on their "own" (read: with round-the-clock help) is a piece of cake. It"s hard to imagine that many people are dumb enough to want children just because Reese and Angelina make it look so glamorous: most adults understand that a baby is not a haircut. But it"s interesting to wonder if the images we see every week of stress-free, happiness-enhancing parenthood aren"t in some small, subconscious way contributing to our own dissatisfactions with the actual experience, in the same way that a small part of us hoped getting "the Rachel" might make us look just a little bit like Jennifer Aniston.

单选题There is extraordinary exposure in the United States to the risks of injury and death from motor vehicle accidents. More than 80 percent of all households own passenger cars or light trucks and each of these is driven an average of more than 11,000 miles each year. Almost one-half of fatally injured drivers have a blood alcohol concentration (BAC) of 0.1 percent or higher. For the average adult, over five ounces of 80 proof spirits would have to be consumed over a short period of time attain these levels. One third of drivers who have been drinking, but fewer than 4 percent of all drivers, demonstrate levels. Although less than 1 percent of drivers with BACs of 0.1 percent or more are involved in fatal crashes, the probability of their involvement is 27 times higher than for those without alcohol in their blood. There are a number of different approaches to reducing injuries in which intoxication plays a role. Based on the observation that excessive consumption correlates with the total alcohol consumption of a country's population, it has been suggested that higher taxes on alcohol would reduce both. While the heavier drinkers would be taxed the most, anyone who drinks at all would be penalized by this approach. To make drinking and driving a criminal offense is an approach directed only at intoxicated drivers. In some states, the law empowers police to request breath tests of drivers cited for any traffic offense and elevated BAC can be the basis for arrest. The National Highway Traffic Safety Administration estimates, however, that even with increased arrests, there are about 700 violations for every arrest. At this level there is little evidence that laws serve as deterrents to drinking while intoxicated. In Britain, motor vehicle fatalities fell 25 percent immediately following implementation of the Road Safety Act in 1967. As the British increasingly recognized that they could drink and not be stopped, the effectiveness declined, although in the ensuing three years the fatality rate seldom reached that observed in the seven years prior to the Act. Whether penalties for driving with a high BAC or excessive taxation on consumption of alcoholic beverages will deter the excessive drinkers responsible for most fatalities is unclear. In part, the answer depends on the extent to which those with high BACs involved in crashes are capable of controlling their intake in response to economic or penal threat. Therapeutic programs which range from individual and group counseling and psychotherapy to chemotherapy constitute another approach, but they have not diminished the proportion of accidents in which alcohol was a factor. In the few controlled trials that have been reported there is little evidence that rehabilitation programs for those repeatedly arrested for drunken behavior have reduced either the recidivism or crash rates. Thus far, there is no firm evidence that Alcohol Safety Action Project supported programs, in which rehabilitation measures are requested by the court, have decreased recidivism or crash involvement for clients exposed to them, although knowledge and attitudes have improved. One thing is clear, however: unless we deal with automobile and highway safety and reduce accidents in which alcoholic intoxication plays a role, many will continue to die.

单选题The secret agent concealed her real mission, therefore many local people were ______ into thinking that she was a good person.

单选题 Once upon a time, innovation at Procter & Gamble flowed one way: from the United States outward. While the large Cincinnati-based corporation was no stranger to foreign markets, it usually sold them products that were already familiar to most Americans. Many Japanese families, for instance, swaddle their babies in Pampers diapers, and lots of Venezuelans brush their teeth with Crest. And of course (company executive assumed) American at home wanted these same familiar, red-white and blue brands. We might buy foreign-made cars, or chocolates, or cameras but household cleaners and detergents? Recently, however, P&G broke with this long-standing tradition. Ariel, a P&G laundry detergent, was born overseas, and is a familiar sight on store shelves in Europe and Latin America. Now bilingual packages of Ariel Ultra, a super-concentrated cleaner, are appearing on supermarket shelves in Los Angeles. Ariel's appearance in the United States reflects demographic changes making Hispanics the nation's fastest-growing ethnic group. Ariel is a hit with this population. In fact, many Mexican immigrants living in Southern California have been "importing" Ariel from Tijuana, Mexico. "Hispanics knew this product and wanted it," says P&G spokeswoman Marie Salvado. "We realized that we couldn't convince them to buy (our) other laundry detergents." P&G hopes that non-Hispanic consumers will give Ariel a try too. Ariel's already strong presence in Europe may provide a springboard for the company to expand into other markets as well. Recently P&G bought Rakona, Czechoslovakia's top detergent maker. Ariel, currently a top seller in Germany, is likely to be one of the first new brands to appear in Czech supermarkets. And Ariel is not the only foreign idea that the company hopes to transplant back to its home territory. Chinch, an all-purpose spray cleaner similar to popular European products, is currently being test-marketed in California and Arizona. Traditionally Americans have used separate cleaners for different types of surfaces, but market research shows that American preferences are becoming more like those in other countries. Insiders note that this new reverse flow of innovation reflects more sweeping changes at Procter & Gamble. The firm has hired many new Japanese, German, and Mexican managers who view P&G's business not as a one-way flow of American ideas, but a two-way exchange with other markets. Says Bonita Austin of the investment firm Wertheim-Schroeder, "When you met with P&G's top managers years ago, you wouldn't have seen a single foreign face." Today "they could even be in the majority." As Procter & Gamble has found, the United States is no longer an isolated market. Americans are more open than ever before to buying foreign-made products and to selling U. S.-made products overseas.

单选题I am afraid to sleep. I have been afraid to sleep for the last few weeks. I am so tired that, finally, I do sleep, but only for a few minutes. It is not a bad dream that wakes me ; it is the reality I took with me into sleep . I try to think of something else. Immediately the woman in the marketplace comes into my mind. I was on my way to dinner last night when I saw her . She was selling skirts. She moved with the same ease and loveliness I often saw in the women of Laos. Her long black hair was as shiny as the black silk of the skirts she was selling . In her hair, she wore three silk ribbons, blue , green, and white. They reminded me of my childhood and how my girlfriends and I used to spend hours braiding ribbons into our hair. I don't know the word for "ribbons" , so I put my hand to my own hair and, with three fingers against my head , I looked at her ribbons and said "Beautiful. " She lowered her eyes and said nothing. I wasn't sure if she understood me(I don't speak Laotian very well). I looked back down at the skirts. They had designs in them: squares and triangles and circles of pink and green silk. They were very pretty. I decided to buy one of those skirts, and I began to bargain with her over the price. It is the custom to bargain in Asia. In Laos bargaining is done in soft voices and easy moves with the sort of quiet peacefulness. She smiled, more with her eyes than with her lips. She was pleased by the few words I was able to say in her language, although they were mostly numbers, and she saw that I understood something about the soft playfulness of bargaining. We shook our heads in disagreement over the price; then, immediately, we made another offer and then another shake of the head. She was so pleased that unexpectedly, she accepted the last offer I made. But it was too soon. The price was too low. She was being too generous and wouldn't make enough money. I moved quickly and picked up two more skirts and paid for all three at the price set; that way I was able to pay her three times as much before she had a chance to lower the price for the larger purchase. She smiled openly then, and, for the first time in months, my spirit lifted. I almost felt happy. The feeling stayed with me while she wrapped the skirts in a newspaper and handed them to me. When I left, though, the feeling left, too. It was as though it stayed behind in marketplace. I left tears in my throat. I wanted to cry. I didn't , of course. I have learned to defend myself against what is hard; without knowing it, I have also learned to defend myself against what is soft and what should be easy. I get up, light a candle and want to look at the skirts. They are still in the newspaper that the woman wrapped them in. I remove the paper, and raise the skirts up to look at them again before I pack them. Something falls to floor. I reach down and feel something cool in my hand. I move close to the candlelight to see what I have. There are five long silk ribbons in my hand, all different colours. The woman in the maketplace! She has given these ribbons to me! There is no defense against a generous spirit, and this time I cry, and very hard, as if I could make up for all the months that I didn't cry.

单选题At the University of California at Los Angeles (UCLA) , a student loaded his class notes into a handheld e-mail device and tried to read them during an exam: a classmate turned him in. At the University of Nevada at Las Vegas (UNLV) students photographed test questions with their cell phone cameras and transmitted them to classmates. The university put in place a new examination-supervision system. "If they"d spend as much time studying, they"d all be A students," says Ron Yasbin, dean of the College of Sciences of UNLV. With a variety of electronic devices, American students find it easier to cheat. And college officials find themselves in a new game of eat and mouse. They are trying to fight would-he cheats in the exam season by cutting off Internet access from laptops(笔记本电脑), demanding the surrender of cell phones before tests or simply requiring that exams be taken with pens and paper. "It is annoying. My hand-writing is so bad," said Ryan Dapremont, 21 who just finished his third year at Pepperdine University in California. He had to take his exams on paper. Dapremont said technology has made cheating easier, but plagiarism(剽窃) in writing papers was probably the biggest problem. Students can lift other people"s writings off the Internet without attributing them. Still, some students said they thought cheating these days was more a product Of the mindset, not the tools at hand. "Some people put too much emphasis on where they"re going to go in the future, and all they"re thinking about is graduate school and the next step," said Lindsay Nicholas, a third-year student at UCLA. She added that pressure to succeed "sometimes clouds everything and makes people do things that they shouldn"t do. " Some professors said they tried to write exams for which it was hard to cheat, posing questions that outside resources would not help answer. Many officials said that they rely on campus honor codes. They said the most important thing was to teach students not to cheat in the first place.
