单选题Man of Few Words Everyone chases success, but not all of us want to be famous. South African writer John Maxwell Coetzee is 1 for keeping to himself. When the 63-year-old man was named the 2003 Nobel Prize winner for literature, reporters were warned that they would find him "particularly difficult to 2 ," Coetzee lives in Australia but spends part of the year teaching at the University of Chicago. He seemed 3 by the news that he won the US $1.3 million prize. "It came as a complete surprise. I wasn"t even aware they were due to make the announcement," he said. His 4 of privacy led to doubts as to whether Coetzee will attend prize-givng in Stockholm, Sweden, on December 10. But despite being described as 5 to track down, the critics agree that his writing is easy to get to know. Born in Cape Town, South Africa, to an English-speaking family, Coetzee 6 his breakthrough in 1980 with the novel "Waiting for the Barbarians". He 7 his place among the world"s leading writers with two Booker prize victories, Britain"s highest honour for novels. Her first 8 in 1983 for the Life and Times of Michael K and his second title came in 1999 for Disgrace. A major theme in his work is South Africa"s former apartheid system, which divided whites from blacks. 9 with the problems of violence, crime and racial division that still exist in the country, his books have enabled ordinary people to understand apartheid 10 within. "I have always been more interested in the past than the future," he said in a rare interview. "The past 11 its shadow over the present. I hope I have made one or two people think 12 about whether they want to forget the past completely." In fact, this purity in his writing seems to be 13 in his personal life. Coetzee is a vegetarian, a cyclist rather than a motorist and he doesn"t drink alcohol. But what he has 14 to literature, culture and the people of South Africa is far greater than the things he has given up. "In looking at weakness and failure in life," the Nobel prize judging panel said, "Coetzee"s work 15 the divine spark in man."

单选题Nanotechnology Many of the grand challenges of today and the future are found in the question: "How are we going to solve the problems and make serious improvements in industrial manufacturing, disease control, environmental pollution control, global climate change, food production, transportation, communication, and others?" Nanotechnology (纳米技术) promises to make revolutionary contributions. Within the next few years we can expect to see major improvements. Here are some possibilities the things to come. Nanotechnology is fundamentally changing the way materials and devices will be produced in the future. Nanostructures, ceramics, polymers, metals, and other materials will have greatly improved mechanical properties. In fact, with the ability to build things atom-by-atom and molecule-by-molecule there will be new classes of structural materials. Nanotechnology will enable products to be lighter, stronger, smarter, cheaper, cleaner and more precise. The ability to synthesize nanoscale budding blocks with precisely controlled size and composition and then to assemble them into larger structures with unique properties and functions will revolutionize segments of the materials manufacturing industry. Nanotechnology is expected to bring about lighter, stronger, and programmable materials; reductions in life-cycle costs through lower failure rates; innovative devices based on new principles and architectures; and use of molecular cluster manufacturing. Nanotechnology will provide new tools for medicine. It could radically change the way surgery is done. It will make it possible to do molecular scale surgery to repair and rearrange cells. Since disease is the result of physical disorder, misarranged molecules and cells, medicine at this level should be able to cure most diseases. Mutations in DNA could be repaired and cancer cells, toxic chemicals, and viruses could be destroyed through use of medical Nan devices. Nanotechnology enabled increases in computational power will permit the characterization of macromolecular networks in realistic environments. Such simulations will be essential elements in the development of biocompatible implants and in the drug discovery process. Nanotechnology has the potential to significantly impact energy efficiency, storage, and production. Nanotechnology can change the economics of energy production.

单选题Sport or Spectacle? Muhammad Ali is probably the most famous sports figure on earth: he is recognized on every continent and by all generations. The 1 of his illness as Parkinson"s disease after his retirement fuelled the debate about the dangers of boxing and criticism 2 the sport. That, plus his outspoken opposition 3 women"s boxing, made people wonder how he would react when one of his daughters decided to 4 up the sport. His presence at Leila"s first professional fight, however, seemed to broadcast a father"s support. Of course Muhammad All wanted to 5 his daughter fight. The ring announcer introduced him as the "the greatest" and as he sat down at the ringside the crowd chanted. Twenty-one-year-old Leila"s debut fight (首次亮相) was a huge success and there was as much publicity for the 6 as her father"s fights once attracted. 7 , Leila"s opponent was much weaker than she was and the fight lasted just 31 seconds. Since then, Laila has won most of her fights by knocking out her opponent. "She knows 8 she"s doing," said one referee about her, "She knows about moving well, You can see some of her dad"s moves." Laila Ali would rather not 9 herself to her father. She prefers to make her own 10 . Her father supports her decision to enter the sport but he has not spared her the details of what can happen. Laila 11 that her father wants her to understand the worst possible scenario (局面) to see 12 she still wants to go forward with it. She knows she"s going to get hit hard at times, that she may get a broken nose or a swollen (肿胀的) face, but at least she is prepared for it. Laila"s decision to start boxing despite her father"s 13 with the symptoms of Parkinson"s disease has of course sparked a mixture of praise and 14 . But Laila is a determined individual and it is her famous last name that has made her a magnet for worldwide media attention. Of course, the 15 on the boxing scene of a woman with her family history attracts even more questions about whether women"s boxing is sport or spectacle.

单选题Forecasting Methods There are several different methods that can be used to create a forecast. The method a forecaster chooses depends Upon the experience of the forecaster, the amount of information available to the forecaster, the level of difficulty that the forecast situation presents, and the degree of accuracy or confidence needed in the forecast. The first of these methods is the persistence method; the simplest way of producing a forecast. The persistence method assumes that the conditions at the time of the forecast will not change. For example, if it is sunny and 87 degree today, the persistence method predicts that it will be sunny and 87 degree tomorrow. If two inches of rain fell today, the persistence method would predict two inches of rain for tomorrow. However, if weather conditions change significantly from day to day, the persistence method usually breaks down and is not the best forecasting method to use. The trends method involves determining the speed and direction of movement for fronts, high and low pressure centers, and areas of clouds and precipitation. Using this information, the forecaster can predict where he or she expects those features to be at some future time. For example, if a storm system is 1,000 miles west of your location and moving to the east at 250 miles per day, suing the trends method you would predict it to arrive in your area in 4 days. The trends method works well when systems continue to move at the same speed in the same direction for a long period of time. if they slow down, speed up, change intensity, or change direction, the trends forecast will probably not work as well. The climatology method is another simple way of producing a forecast. This method involves averaging weather statistics accumulated over man years to make the forecast. For ex- ample, if you were using the climatology method to predict the weather for new York City on July 4th, you would go through all the weather data that has been recorded for every July 4th and take an average. The climatology method only works well when the weather pattern is similar to that expected for the chosen time of year. if the pattern is quite unusual for the given time of year, the climatology method will often fail. The analog method is a slightly more complicated method of producing a forecast. It involves examining today's forecast scenario and remembering a day in the past when the weather scenario looked very similar (an analog). The forecaster would predict that the weather in this forecast will behave the same as it did in the past. The analog method is difficult to use because it is virtually impossible to find a predict analog. Various weather features rarely align themselves in the same locations they were in the previous time. Even small differences between the current time and the analog can lead to very different results.

单选题Who (Doesn't) Let the Dogs Bark? For the past year, Cornelia Czarnecki said, the barking of her neighbor's German shepherd has awakened her repeatedly at 4 am. The dog often barks for hours at a time, said Mrs. Czarnecki, a Clifton resident. "That dog is out there barking day and night, and we don't know .what to do anymore," she said. Mrs. Czarnecki became so upset about the dog that she filed a municipal complaint against him under the town's general noise ordinance. The case is set to be heard in municipal court on August 6. Complaints like the ones Mrs. Czarnecki lodged with the police and city officials led the Clifton City Council to draft an ordinance that could result in fines for residents whose dogs are "barking, howling, crying" or making any other loud noises for more than 30 minutes in an hour. "I can't wait," Mrs. Czarnecki said. The council took up the ordinance for a first reading on Tuesday; a final vote is scheduled on August 8. "It's a quality of life issue," said Councilman Frank C Fusco, who introduced the measure. Clifton is far from alone in seeking to silence noisy dogs. At least 144 of New Jersey's municipalities have laws that address whining and barking, according to a municipal ordinance database online at www.generalcode.com. In New York, at least 30 towns in Nassau and Suffolk Counties have similar laws, as do about 25 towns in Westchester County. Connecticut has a statewide law barring dogs that are a "nuisance" because of "excessive barking or other disturbance." Many of the ordinances in the region are general prohibitions against excessive whining or barking. In Westchester, the City of New Rochelle ran into trouble with its law in 1997 after a resident challenged a citation. A city judge ruled that the ordinance was unconstitutionally vague because it did not include details about time of day and duration of barking, and the city changed the law in 1998. "Many of these ordinances go back to the 1800s," said the New Rochelle corporation counsel, Bernis Shapiro." They're just carried forward and they don't get changed until an issue comes up." In May 2006, Hillsborough Township in Somerset County passed an ordinance to specifically address barking, but no complaints have been filed since then, said Lt. Bill Geary of the Hillsborough Police Department. Other New Jersey towns, including Bloomsbury in Hunterdon County and Manville in Somerset, considered such ordinances but withdrew them after residents complained that they would be unenforceable. As for those who contend that a barking dog should be a low priority, Councilman Fusco said, "If the dog was next to your house, you'd sing a different song." Mr. Fusco said he was confident that the ordinance proposed in Clifton would be supported by his fellow council members. At the same time, he knows that some residents may object. But David Axelrod, a groomer at Furrs N Purrs on Valley Road, said he did not think the measure was tough enough. "Thirty minutes is extremely generous," he said. "There is no reason why a dog should be barking that long." The ordinance says barking must be sustained to be illegal, and it bans excessive barking only from 10 pm to 7 am. Under the ordinance, a resident complains to the City Health Department, which sends a warning note. If the barking continues, the resident takes the complaint to municipal court, where fines can start at $250. Before a court date, the city would most likely try to resolve the matter through mediation, said the city attorney, Matthew T. Priore. Last year about a dozen warning letters were sent to residents about their barking dogs, Clifton officials said. Currently, residents can complain about barking under the city's general noise ordinance, but they have to essentially prosecute the case in municipal court themselves, Mr. Fusco said. Under the proposed ordinance, residents would appear as a witness in a case presented by the municipal prosecutor. "The new ordinance has some bite to it," Mr. Fusco said. Eric M. Zwerling, director of the Rutgers University Noise Technical Assistance Center, trains police officers on noise complaints and writes municipal noise codes. "One of the things I say to the officers I train is that if people were fundamentally civil to each other, we'd all be out of work," he said. Mr. Zwerling, the owner of a chocolate Labrador named Bosco, said he had his own appreciation of the barking problem. "A dog is barking for one of two reasons -- either it needs attention or it is trying to alert you to something," he said. "In either case, you should be attending to it./
