单选题 Will Quality Eat Up the U.S. Lead in Software? If U.S. software companies don't pay more attention to quality, they could kiss their business goodbye. Both India and Brazil are developing a world-class software industry. Their weapon is quality and one of their jobs is to attract the top U.S. quality specialists whose voices are not listened to in their country. Already, of the world's 12 software houses that have earned the highest rating in the world, seven are in India. That's largely because they have used new methodologies rejected by American software specialists. For example, for decades, quality specialists, W. Edwards Deming and J.M. Juran had urged U.S. software companies to change their attitudes to quality. But their quality call mainly fell on deaf ears in the U.S. —but not in Japan. By the 1970s and 1980s, Japan was grabbing market share with better, cheaper products. They used Deming's and Juran's ideas to bring down the cost of good quality to as little as 5% of total production costs. In U.S. factories, the cost of quality then was 10 times as high: 50% In software, it still is. Watts S. Humphrey spent 27 years at IBM heading up software production and then quality assurance. But his advice was seldom paid attention to. He retired from IBM in 1986. In 1987, he worked out a system for assessing and improving software quality. It has proved its value time and again. For example, in 1990 the cost of quality at Raytheon Electronics Systems was almost 60% of total software production costs. It fell to 15% in 1996 and has since further dropped to below 10%. Like Deming and Juran, Humphrey seems to be winning more praises overseas than at home. The Indian government and several companies have just founded the Watts Humphrey Software Quality Institute at the Software Technology Park in Chennai, India. Let's hope that U.S. lead in software will not be eaten up by its quality problems.

单选题No Jetlag(时差反应) Anymore Most people who travel long distances complain of jetlag(时差反应). Jetlag makes business travelers less productive (对产的，有成效的) and more prone (51) making mistakes. It is actually caused by (52) of your "body clock"-a small cluster(串、组、群)of brain cells that controls the timing of biological (53) . The body clock is designed for a regular rhythm(节奏)of daylight and darkness, so that it is thrown out of balance when it experiences daylight and darkness at the "wrong" times in a new time zone. The (54) of jetlag often persist(持续) for days (55) the internal body clock slowly adjusts to the new time zone. Now a new anti-jetlag system is available that is based on proven, (56) and pioneering scientific research. Dr. Martin Moore has devised a practical strategy to adjust the body clock much sooner to the new time zone (57) controlled exposure to bright light. The time zone shift(转换) is easy to accomplish and eliminates (消除) (58) of the discomfort of jetlag. A successful time zone shift depends on knowing the exact times to either (59) or avoid bright light. Exposure to light at the wrong time can actually make jetlag worse. The proper schedule (60) light exposure depends a great deal on (61) travel plans. Data on a specific flight itinerary (旅行路线) and the individual's sleep (62) are used to produce a trip guide with (63) on exactly when to be exposed to bright light. When the trip guide calls (64) bright light you should spend time outdoors if possible. If it is dark outside, or the weather is bad, (65) you are on an air plane, you can use a special light device to provide the necessary light stimulus(刺激) for a range of activities such as reading, watching TV or working.

单选题Science and Truth "FINAGLE" is not a word that most people associate with science. One reason is that the image of the scientist is of one who always collects data in an impartial (51) for truth. In any debate - over intelligence, schooling, energy-the (51) "science says" usually disarms opposition. But scientists have long acknowledged the existence of a "finagle factor"—a tendency by many scientists to give a helpful change to the data to (53) desired results. The latest of the finagle factor in action comes from Stephen Jay Gould, a Harvard biologist, (54) has examined the important 19th century work of Dr. Samuel George Morton. Morton was famous in his time (55) analysing the brain size of the skulls as a measure of intelligence. He concluded that whites had the (56) brains, that the brains of Indians and Blacks were smaller, and therefore, that whites constitute a superior race. Gould went back to Morton's original data and concluded that the (57) were an example of the finagle at work. He found that Morton's "discovery" was made by leaving out embarrassing data, using incorrect procedures, making simple arithmetical (58) (always in his favour) and changing his criteria-again, always in favour of his argument. Morton has been thoroughly discredited by now and scientists do not believe that brain size reflects (59) . But Gould went on to say Morton's story is only an example of a common problem in (60) work. Some of the leading figures in science are believed to have (61) the finagle factor. Gould says that Isaac Newton fudged out to support at least three central statements that he could not prove. And so (62) Claudius Ptolemy, the Greek astronomer, whose master work, Almagest, summed up the case for a solar system that had the earth as its centre. Recent studies indicate that Ptolemy (63) faked some key data or resorted heavily to the finagle factor. All this is (64) because the finagle factor is still at work. For example, in the artificial sweetener controversy, for example, it is said that all the studies sponsored by the sugar industry find that the artificial sweetener is unsafe, while all the studies sponsored by the diet food industry find nothing (65) with it.

单选题{{B}}第三篇{{/B}} Can Buildings Be Designed to Resist Terrorist Attack In the aftermath of the terrorist attack on the World Trade Center, structural engineers are trying hard to solve a question that a month ago would have been completely unthinkable.. Can building be designed to withstand catastrophic (灾难的) blasts inflicted by terrorists? Ten days after the terrorist attacks on the twin towers, structural engineers from the University at Buffalo (布法罗) and the Multidisciplinary Center for Earthquake Engineering Research (MCEER) headquartered(总部) at UB traveled to ground zero as part of a project funded by the National Science Foundation. Visiting the site as part of an MCEER reconnaissance visit. They spent two days beginning the task of formulating ideas about how to design such structures and to search for clues on how to do so in buildings that were damaged, but still are standing. "Our objective in visiting ground zero was to go and look at the buildings surrounding the World Trade Center, those buildings that are still standing,but that sustained damage," said Mr. Bruneau, Ph. D. "Our immediate hope is that we can develop a better understanding as to why those buildings remain standing,while our long-term goal is to see whether earthquake engineering technologies can be married to existing technologies to achieve enhanced performance of buildings in the event of terrorist attacks. " he added. Photographs taken by the investigators demonstrate in startling detail the monumental damage inflicted on the World Trade Center towers and buildings in the vicinity. One building a block away from the towers remains standing, but was badly damaged. "This building is many meters away from the World Trade Center and yet we see a column there that used to be part of mat building. " explained A. Whittaker, Ph. D. "The column became a missile that shot across the road,through the window and through the floor. The visit to the area also revealed some surprises, according to the engineers. For example, the floor framing system in one of the adjacent buildings was quite rugged (高低不平的) ,allowing floors that were pierced by tons of falling debris to remain intact. "Highly redundant ductile framing systems may provide a simple, but robust strategy for blast resistance, "he added. Other strategies may include providing alternate (交替) paths for gravity loads in the event that a load-bearing column fails. "We also need a better understanding of the mechanism of collapse. " said A. Whittaker. "We need to find out what causes a building to collapse and how you can predict it. " A. Reinhorn, Ph.D. noted that "earthquake shaking has led to the collapse of many buildings in the past. It induces, dynamic response and extremely high stresses and deformations in structural components (成分). Solutions developed for earthquake-resistant design may be directly applicable to blast engineering and terrorist-resistant design. Part of our mission now at UB is to transfer these solutions and to develop new ones where none exist at present. "

单选题 More Than a Ride to School The National Education Association claims, "The school bus is a mirror of the community." They further add that, unfortunately, what appears on the exterior does not always reflect the reality of a chosen community. They are right -- sometimes it reflects more! Just ask Lies! Denson. Riding the school bus has been more than a ride to school for Lies!. Bruce Hardy, school bus driver for Althouse Bus Company has been Liesl's bus driver since kindergarten. Last year when Liesl's family moved to Parkesburg, knowing her bus went by her new residence, she requested to ride the same bus. This year Liesl is a senior and will enjoy her last year riding the bus. She says, "It's been a great ride so far! My bus driver is so cool and has always been a good friend and a good listener. Sometimes when you're a child adults do not think that what you have to say is important. Mr. Hardy always listens to what you have to say and makes you feel important." Her friends Ashley Batista and Amanda Wolfe agree. Bruce Hardy has been making Octorara students feel special since 1975. This year he will celebrate 30 years working for Althouse Bus Company. Larry Althouse, president of the company, acknowledges Bruce Hardy's outstanding record: "You do not come by employees like Bruce these days. He has never missed a day of work and has a perfect driving record. He was recognized in 2000 by the Pennsylvania School Bus Association for driving 350,000 accident free miles. Hardy's reputation is made further evident through the relationships he has made with the students that ride his bus." Althouse further adds, "AIthouse Bus Company was established 70 years ago and has been providing quality transportation ever since. My grandfather started the business with one bus. Althouse Bus Company is delighted to have the opportunity to bring distinctive and safe service to our local school and community and looks forward to continuing to provide quality service for many more years to come." Three generations of business is not all the company has enjoyed. Thanks to drivers like Bruce Hardy, they have been building relationships through generations. Liesl's mother Carol also enjoys fond memories of riding Bruce Hardy's bus to the Octorara School District.

单选题Some People Do Not Taste Salt Like Others Low-salt foods may be harder for some people to like than others, according to a study by a Penn State College of Agricultural Sciences food scientist. The research indicates that genetic factors influence some of the difference in the levels of salt we like to eat. Those conclusions are important because recent, well-publicized (大力宣传的) efforts to reduce the salt content in food have left many people struggling to accept food that simply does not taste as good to them as it does to others, pointed out John Hayes, lead investigator on the study. Diets high in salt can increase the risk of high blood pressure and stroke. That is why public health experts and food companies are working together on ways to help consumers lower salt intake through foods that are enjoyable to eat. This study increases understanding of salt preference and consumption. The research involved 87 carefully screened participants who sampled salty foods such as soup and chips, on multiple occasions, spread out over weeks. Test subjects were 45 men and 42 women, reportedly healthy, ranging in age from 20 to 40. They rated the intensity of taste on a commonly used scientific scale, ranging from barely detectable to strongest sensation of any kind. "Most of us like the taste of salt. However, some individuals eat more salt, both because they like the taste of saltiness more, and because it is needed to block other unpleasant tastes in food," said Hayes. "Supertasters, people who experience tastes more in tensely, consume more salt than nontasters. Snack foods have saltiness as their primary flavor, and at least for these foods, more is better, so the supertasters seem to like them more. " However, supertasters also need higher levels of salt to block unpleasant bitter tastes in foods such as cheese, Hayes noted. "For example, cheese is a wonderful blend of dairy flavors from fermented (发酵的) milk, but also bitter tastes from ripening that are blocked by salt," he said. "A supertaster finds low-salt cheese unpleasant because the bitterness is too pronounced." Hayes cited research done more than 75 years ago by a chemist named Fox and a geneticist named Blakeslee, showing that individuals differ in their ability to taste certain chemicals. As a result, Hayes explained, we know that a wide range in taste acuity (敏锐) exists, and this variation is as normal as variations in eye and hair color.
