单选题Thanks to closed doors and fierce gatekeepers, bosses are tricky to observe in their natural habitat. Yet it might be useful to know what they do all day, and whether any of it benefits shareholders. A new Harvard Business School working paper sheds some light. Researchers asked the chief executives of 94 Italian firms to have their assistants record their activities for a week. You may take this with a grain of salt. Is the boss's assistant a neutral observer? If the boss spends his lunch hour boozing, or in a motel with his assistant, will she record this truthfully? Nonetheless, here are the results. The average Italian boss works for 48 hours a week and spends 60% of that time in meetings. The most diligent put in another 20 hours. And the longer they work, the better the company does. Less diligent chief executives are more likely to have one-to-one meetings with people from outside the company. The authors speculate that such people are trying to raise their own profile, perhaps to secure a better job. Bosses who work longer hours, by contrast, spend more of them meeting their own employees. Bosses often complain that they get bogged down in day-to-day operations, says Rajesh Chandy, a professor at the London Business School. Regulations that make them legally responsible for their underlings' wrongdoings are partly to blame. The prospect of jail is a powerful attention-grabber. Many bosses also feel they must dash around the world pitching to clients. Jim Hagemann Snabe, co-chief executive of SAP, a software firm, reckons that he met over 200 last year. Mr. Chandy thinks bosses should spend less time with clients and more time thinking about the future. How much time they spend thinking about anything is hard to measure. But in an experiment, Mr. Chandy measured how often bosses use forward-looking words like "will" and "shall" in their public statements. He concluded that bosses spend only 3 -4% of their day thinking about long-term strategy. Brian Sullivan, the chief executive of CTPartners, a headhunting firm, says the most difficult part of his job is saying no to people who want a piece of his time. "If it was up to our partners I would be at every pitch, " he says. Mr. Sullivan says the only time he gets for blue-sky thinking is when he is in the sky. "Chief executives will rue the day when BlackBerrys work on planes, " he predicts. Bill Gates took regular "think weeks" , when he would sit alone in a cabin for 18 hours a day reading and contemplating. This, it is said, led to such strategic masterstrokes as "the internet tidal wave memo" in 1995, which shifted Microsoft's focus(some say belatedly)to the web. But not every boss thinks he needs more time for thinking. "You can hire McKinsey to do that for you, " says one.

单选题选出应填入下面一段英语中______内的正确答案。 All known techniques for handling complex problems successfully seem to fall into one of the three classes: subdividing the problem (1) , ignoring irrelevant detailin a safe way (2) , and having an independent agent (3) the internal consistency (contextual checking) The first two provide guidelines for solving the problem, the third serves to provide early warnings. A good programming language supports all three. In subdividing problem, some of the subproblems may be similar to the (4) problem. It leads us to a (5) solution. This (5) solution is viable provided each of the subproblems is easier to solve than the original problem.

单选题Tattoos didn't spring up with the dawn of biker gangs and rock 'n' roll bands. They've been around for a long time and had many different meanings over the course of history. For years, scientists believed that Egyptians and Nubians were the first people to tattoo their bodies. Then, in 1991, a mummy was discovered, dating back to the Bronze Age of about 3300 B.C. "The Iceman," as the specimen was dubbed, had several markings on his body, including a cross on the inside of his knee and lines on his ankle and back. It is believed these tattoos were made in a curative effort. Being so advanced, the Egyptians reportedly spread the practice of tattooing throughout the world. The pyramid-building third and fourth dynasties of Egypt developed international nations with Crete, Greece, Persia and Arabia. The art tattooing stretched out all the way to Southeast Asia by 2000 B. C. Around the same time, the Japanese became interested in the art but only for its decorative attributes, as opposed to magical ones. The Japanese tattoo artists were the undisputed masters. Their use of colors, perspective, and imaginative designs gave the practice a whole new angle. During the first millennium A.D., Japan adopted Chinese culture in many aspects and confined tattooing to branding wrongdoers. In the Balkans, the Thracians had a different use for the craft. Aristocrats, according to Herodotus, used it to show the world their social status. Although early Europeans dabbled with tattooing, they truly rediscovered the art from when the world exploration of the post-Renaissance made them seek out new cultures. It was their meeting with Polynesian that introduced them to tattooing. The word, in fact is derived from the Polynesian word tattoo, which means "to mark". Most of the early uses of tattoos were ornamental. However, a number of civilizations had practical applications for this craft. The Goths, a tribe of Germanic barbarians famous for pillaging Roman settlements, used tattoos to mark their slaves. Romans did the same with slaves and criminals. In Tahiti, tattoos were a rite of passage and told the history of the person's life. Reaching adulthood, boys got one tattoo to commemorate the event. Men were marked with another style when they got married. Later, tattoos became the souvenir of choice for globetrotting sailors. Whenever they would reach an exotic locale, they would get a new tattoo to mark the occasion. A dragon was a famous style that meant the sailor had reached a "China station. " At first, sailors would spend their free time on the ship tattooing themselves and their mates. Soon after, tattoo parlors were set up in the area, surrounding ports worldwide. In the middle of the 19th century, police officials believed that half of the criminal underworld in New York City had tattoos. Port areas were renowned for being rough places full of sailors that were guilty of some crime or another. This is most likely how tattoos got such a bad reputation and became associated with rebels and delinquents.

单选题Maybe ten-year-old Elizabeth put it best when she said to her father, "But, Dad, you can't be healthy if you're dead." Dad, in a hurry to get home before dark so he could go for a run, had forgotten to wear his safety belt—a mistake 75% of the US population make every day. The big question is why. There have been many myths about safety belts ever since their first appearance in cars some forty years ago. The following are three of the most common. Myth Number One: It's best to be "thrown clear" of a serious accident. Truth: Sorry, but any accident serious enough to "throw you clear" is also going to be serious enough to give you a very bad landing. And chances are you'll have traveled through a windshield (挡风玻璃) or door to do it. Studies show, that chances of dying after a car accident are twenty-five times greater in cases where people are "thrown clear." Myth Number Two: Safety belts "trap" people in cars that are burning or sinking in water. Truth: Sorry, again, but studies show that people knocked unconscious (昏迷) due to not wearing safety belts have a greater chance of dying in these accidents. People wearing safety belts are usually protected to the point of having a clear head to free themselves from such dangerous situation, not to be trapped in them. Myth Number Three: Safety belts aren't needed at speeds of less than 30 miles per hour (mph). Truth: When two cars traveling at 30 mph hit each other, an unbelted driver would meet the windshield with a force equal to diving headfirst into the ground from a height of 10 meters.

单选题{{B}}Passage Four{{/B}} After retirement from medical research, my wife and I built our home in a gated community surrounded by yacht clubs and golf courses on Hilton Head Island. But when I left for the other side of the island, I was traveling on unpaved roads lined with leaky cottages. The "lifestyle" of many of the native islanders stood in shocking contrast to my comfortable existence By talking to the local folks, I discovered that the vast majority of the maids, gardeners, waitresses and construction workers who make this island work had little or no access to medical care. It seemed outrageous to me. I wondered why someone didn't do something about that. Then my father's words, which he had asked his children daily when they were young, rang in my head again: "What did you do for someone today?" Even though my father had died several years before, I guess I still didn't want to disappoint him. So I started working on a solution. The island was full of retired doctors. If I could persuade them to spend a few hours a week volunteering their services, we could provide free primary health care to those so desperately in need of it. Most of the doctors I approached liked the idea, so long as they could be relicensed without troubles. It took one year and plenty of persistence, but I was able to persuade the state legislators to create a special license for doctors volunteering in not-for-profit clinics. The town donated land, local residents contributed office and medical equipment and some of the potential patients volunteered their weekends ornamenting the building that would become the clinic. We named it Volunteers in Medicine and we opened its doors in 1994, fully staffed by retired physicians, nurses and dentists as well as nearly 150 nonprofessional volunteers. That year we had 5,000 patient visits; last year we had 16,000. Somehow word of what we were doing got around. Soon we were receiving phone calls from retired physicians all over the country, asking for help in starting VIM clinics in their communities. We did the best we could--there are now 15 other clinics operating--but we couldn't keep up with the need. Yet last month I think my father's words found their way up north, to McNeil Consumer Healthcare, the maker of Tylenol (泰诺: 一种感冒药). A major grant from McNeil will allow us to respond to these requests and help establish other free clinics in communities around the country.

单选题A poor traveler stopped under the tree to eat the boiled rice and vegetables which he brought with him. A few meters away, there was a small shop by the side of the road where a woman was frying fish and selling it to travelers. The woman watched the poor traveler carefully, and when he finished his food and began to go, she shouted rudely, "You have not paid me for the fried fish? "But I have not had any fried fish!" he said. "But everyone can see that you enjoyed the smell of my fried fish with your rice and veg- etables," said the woman, "If you had not smelled the fish, your meal would not have been so pleasant !" Soon a crowd collected, and although they supported the poor traveler, they had to ad- mit that wind was blowing from the shop to the place where he had eaten, and that it had carried the smell of the fried fish to him. Finally, the woman took the poor traveler to a judge, who said, "The woman says that the traveler ate his meal with the smell of her fried fish. The traveler agrees that the wind was blowing the smell of her fried fish to his nose while he was eating, so he must pay for it." "What does your fried fish cost?" he asked the woman. "Twenty-five cents a plate," she answered delighted. "Then go outside together," said the judge. "There the traveler must hold up a twenty five-cent piece so that a shadow(影子) falls on the woman's hand. The price of the smell of a plate of fried fish is the shadow of twenty-five cents./
