1、Singing Alarms Could Save the BlindIf you cannot see, you may not be able to find your way out of a burning building and that could be fatal. A company in Leeds could change all that with directional sound alarms capable of guiding you to the exit. Sound Alert, a company run by the University of Leeds, is installing the alarms in a residential home forblind people in Sommersetand a resource centre forthe blind in Columbia. The alarms produce a wide range of frequencies that enable the brain to determine where the sound is coming from. Deborah Withington of Sound Alert says that the alarms use most of the frequencies that can be heard by humans. "It\'s a burst of white noise that people say sounds like static on the radio," she says. "Its life-saving potential is great."She conducted an experiment in which people were filmed by thermal-imaging cameras trying to find their way out of a large smoke-filled room. It took them nearly four minutes to find the doorwithout a sound alarm, but only 15 seconds with one. Withington studies how the brain ______ sounds at the university. She says that the source of a wide band of frequencies can be pinpointed more easily than the source of a narrow band. Alarms basedon the same concept have already been installed on emergency vehicles. The alarms will also include rising orfalling frequencies to indicate whether people should go up ordown stairs. They were developed with the aid of a large grant from British Nuclear Fuels. 【单选题】
A.processes
B.produces
C.possesses
D.proceeds
正确答案:A
答案解析:句子主语是the brain,应和“处理”构成主谓关系,其他动词均不合适。所以选择A。
2、Breastfeeding Can Cut Cardiovascular RiskBreastfeeding can reduce the risk of a heart attack orstroke later in life and could prevent hundreds of thousands of deaths each year, researchers said on Friday. Babies who are breastfed have fewer childhood infections and allergies and are less prone to obesity. British scientists have now shown that breastfeeding and slow growth in the first weeks and months of life has a protective effect against cardiovascular disease. "Diets that promote more rapid growth put babies at risk many years later in terms of raising their blood pressure, raising their cholesterol and increasing their tendency to diabetes and obesity-the four main risk factors forstroke and heart attack." said ProfessorAlan Lucas of the Institute of Child Health in London. "Our evidence suggests that the reason why breast-fed babies do better is because they grow more slowly in the early weeks."Lucas said the effects of breastfeeding on blood pressure and cholesterol later in life are greater than anything adults can do to control the risk factors forcardiovascular disease, other than taking drugs. An estimated 17 million people die of cardiovascular disease, particularly heart attack and strokes, each year, according to the World Health Organization. Lucas and his colleagues compared the health of 216 teenagers who as babies had either been breastfed orgiven different nutritional baby formulas\' They reported their ______ in The Lancet medical journal. The teenagers who had been breastfed had a 14 percent lower ratio of bad to good cholesterol and lower concentrations of a protein that is a marker forcardiovascular disease risk. The researchers also found that regardless of the child\'s weight at birth, the faster the infants grew in the early weeks and months of life, the greater was their later risk of heart disease and stroke. The effect was the same forboth boys and girls. "The more human milk you have in the newborn period, the lower your cholesterol level is, the lower your blood pressure is 16 years later, "Lucas said. 【单选题】
A.thoughts
B.findings
C.viewpoints
D.breakthrough
正确答案:B
答案解析:上文提到了他们的调查研究,接下来应该出现的是他们的“研究结果”。
3、The Book of LifeSo far, scientists have named about 1.6 million living species, and that\'s a just a fraction of that probably exists on Earth. With so many plants, animals and other creatures coveting the planet, it can be tough to figure out what type of spider is moving up your leg orwhat kind of bird is flying by.A soon - to - be - started Web site might help. An international team of researchers has announced the creation of Web - based Encyclopedia of life( EOL). The project aims to catalog every species on Earth in a single, easy - to - use reference guide.To get the encyclopedia started, the creators will use information from scientific databases that already exist. and eventually, in special sections of the site, nonscientist with specialized knowledge will get to join in. Bird - watchers, forexample, will be able to input which bird they\'ve seen and where. The technology forthis kind of tool has only become available.As the EOL develops, you might find it useful forschool projects. The site will feature special pages forkids who are studying ecosystems (生态系统) in their neighborhoods. To make sure the encyclopedia is accurate, scientists will review much of the information added to it. People who visit the site will be able to choose to leave out pages that haven\'t been reviewed.Another convenient feature of the EOL is that you\'ll be able to pick the level of detail you want to see to match your interest, age and knowledge. If you wanted to learn about bears fora science class report, forexample, you could use the "novice" setting to get basic information about the animals. On the "expert" setting, on the other hand, you could get much more detailed information about the history, literature and exploration of bears.It now takes years forscientist to collect all the data they need to describe and analyze species. The creatorof the Encyclopedia of Life hope that their new tool will speed up that process.The word "novice" in Paragraph 5 could be best replaced by ______.【单选题】
A.scientist
B.creator
C.beginner
D.expert
正确答案:C
答案解析:本题难度较大,需要很强的把握词义能力。本题可以先看选项得到信息提示,也可以结合原文的提示:you could use the“novice”setting to get basic information about the animals. On the “expert” setting, on the other hand, you could get much more detailed information…,可以看出,novice的意思和basic相近,和expert相反,回来看选项,C项和原文句意相近,是答案。
4、The great change of the city astonished all the visitors.【单选题】

5、A Great Quake Coming?Everyone lives in San Francisco knows that earthquakes are common in the Bay Area and they can devastate. In 1906, forexample, a majorquake destroyed about 28000 buildings and killed hundreds, perhaps thousands of people. Residents now wonder when will the next "Big One" strike. It\'s bound to happen someday. At least seven active fault(断层) lines run through the San Francisco area. Faults are places where pieces of Earth\'s crust (地壳) slide past each other. When these pieces slip, the ground shakes.To prepare forthat day, scientists are using new techniques to reanalyze the 1906 earthquake and predict how bad the damage might be when the next one happens.One new finding about the 1906 quake is that the San Andreas Fault split apart faster than scientists had assumed at the time. During small earthquakes, faults rupture(断裂) about 2.7 kilometers persecond. During bigger quakes, however, ruptures can happen faster than 3.5 kilometers persecond.At such high speeds, massive amounts of pressure build up, generating underground waves that can cause more damage than the quake itself. Lucky forSan Francisco, these pressure pulses (脉冲) traveled away from the city during the 1906 event.Looking ahead, scientists are trying to predict when the next majorquake will occur. Records show that earthquakes were common before 1906. Since then, the area has been relatively quiet. Patterns in the data, however, suggest that the probability of a majorearthquake striking the Bay Area before 2032 is at least 62 percent.New buildings in San Francisco are quite safe in case of future quakes. Still, more than 84 percent of the city\'s buildings are old and weak. Analyses suggest that another massive earthquake would cause extensive damage.People who live there today tend to feel safe because San Francisco has remained pretty quiet fora while. According to the new research, however, it\'s not a matter that whether "the Big One" will hit here. It\'s just a matter of when.Scientists will be able to predict the exact time of an earthquake soon.【单选题】
A.Right
B.Wrong
C.Not mentioned
正确答案:C
答案解析:本题难度较大,没有明显的答案依据,需要通读全文,做出判断。第五段第一句:Looking ahead, scientists are trying to predict when the next majorquake will occur.{炎到展望未来,科学家正努力预测下次大地震的发生,但全文只谈到在积极预测地震,没有提及是否能够预测出准确的时间,所以本题未提及,答案是C。
6、Arctic MeltEarth\'s North and South Poles are famous forbeing cold and icy. Last year, however, the amount of ice in the Arctic Ocean (北冰群) fell to a record low.Normally, ice builds in Arctic waters around the North Pole each winter and shrinks(缩小) during the summer. But formany years, the amount of ice left by the end of summer has been declining.Since 1979, each decade has seen an 11.4 percent drepin end of summer ice cover. Between 1981 and 2000, ice in the Arctic lost 22 percent of its thickness, becoming 1.13 meters thinner.Last summer, Arctic sea ice reached its thinnest levels. By the end of summer 2007, the ice had shrunk to cover just 4.2 million square kilometers. That\'s 38 percent less area than the average cover at that time of year. and it\'s a very large 23 percent below the previous record low, which was setjust 2 years ago. This continuing trend has made scientists concerned to.There may be several reasons forthe ice melt, says Jinlun Zhang, an oceanographer (海洋学家)at the University of Washington in Seattle. Unusually strong winds blew through the Arctic last summer. The winds pushed much of the ice out of the central Arctic, leaving a large area of thin ice and open water.Scientists also suspect that fewer clouds cover the Arctic now than in the past. Clearer skies allow more sunlight to reach the ocean. The extra heat warms both the water and the atmosphere. In parts of the Arctic Ocean last year, surface temperatures were 3.57 Celsius warmer than the average and 1.5c warmer than the previous record.With both air and water getting warmer, the ice is melting from both above and below. In some parts of the Beaufort Sea, north of Alaska and western Canada, ice that measured 3.3 meters thick at the beginning of the summer was measured just 50 cm by season\'s endThe new measurements suggest that melting is far more severe than the thinking of scientists. Some scientists fear that the Arctic is stuck in a warming trend.What may be some of the reasons forthe ice melt in the Arctic? ______【单选题】
A.Unusually strong winds and clearer skies.
B.Heavy clouds and light winds.
C.Longer summers and shorter winters.
D.Thin ice and open water.
正确答案:A
答案解析:本题有一定的难度,但答案依据还是比较明显,不过跨越了两个段落,文章第五段谈到去年有强风刮过北极,第六段谈到科学家怀疑云层少了,所以答案是A。
7、Strike in MTV NetworksScores of workers from MTV Networks walked off the job yesterday afternoon, filling the sidewalk outside the headquarters of its corporate parent, Viacom, to protest recent changes in benefits. The walkout highlighted the concerns of a category of workers who are sometimes called permalancers: permanent freelancers who work like full-time employees but do not receive the same benefits.Waving signs that read "Shame on Viacom", the workers, most of them in their 20s, demanded that MTV Networks reverse a plan to reduce health and dental benefits forfreelancers beginning Jan. 1. In a statement, MTV Networks noted that its benefits program forfull-time employees had also undergone changes, and it emphasized that the plan forfreelancers was still highly competitive within the industry. Many freelancers receive no corporate benefits. But some of the protesters asserted that corporations were competing to see which could provide the most mediocre health care coverage. Matthew Yonda, who works at Nickelodeon, held a sign that labeled the network "Sick-elodeon". "I\'ve worked here every day forthree years-I\'m not a freelancer," Mr. Yonda said. "They just call us freelancers in orcerto bar us from getting the same benefits as employees."The changes to the benefits package were announced last Tuesday. Freelancers were told that they would become eligible forbenefits after 160 days of work, beginning in January. While that eased previous eligibility rules, which required freelancers to work for52 weeks before becoming eligible, it would have required all freelancers not yet eligible forbenefits to start the waiting period over again on Jan. 1. The 401 (k) plan was also removed On Thursday, acknowledging the complaints, MTV Networks reinstated the 401 (k) plan and said freelancers who had worked consistently since March would be eligible.Fueled by a series of blog posts on the media web site Gawker-the first post was headlined "The Viacom Permalance Slave System" -a loose cohort of freelancers created protest stickers and distributed walkout fliers last week. Caroline O\'Hare, a unit manager who has worked forMTV formore than two years, said the new health care plan-with higher deductibles and a $ 2,000 cap on hospital expenses each year-had provoked outrage. "They think they can treat us like children that don\'t have families, mortgages ordreams of retirement," she said.Outside Viacom\'s headquarters, several workers held posters with the words, "There\'s too many of us to ignore." It was unclear how many freelancers are on the company\'s payroll; an MTV Networks spokeswoman said the figure was not known because it rises and falls throughout the year. The company has 5,500 full-time employees, excluding freelancers, around the world.Two freelancers and one full-time employee, who asked not to be identified forfear of retribution, estimated that the percentage of freelancers in some departments exceeded 75 percent. Another laboraction is expected to take place outside Viacom later this week. Members of the Writers Guild of America, who have been on strike forfive weeks, are expected to picket there on Thursday.The MTV Networks spokeswoman did not provide the number of freelancers on the payroll mostly probably because ______.【单选题】
A.the figure fluctuates throughout the year and it is impossible to calculate the precise number
B.the company wants to keep it as a secret so as to better stand the protest
C.the company has no record of the freelancers since there is no such necessity
D.the company does not want to provide the freelancers with benefits enjoyed by the full-time employee
正确答案:B
答案解析:细节考查题。题干问的是MTV网络发言人没有提供薪水册上自由职业者的数量的最有可能的原因。答案参见第五段,MTV网络发言人声称这个数字全年都来回波动,但实际上公司掌握自己员工的具体数量应该很容易,很明显是因为公布该数据对公司不利,不想让外人知道,以便在这场罢工斗争中占据优势地位。
8、A Star Is Born1 The VLT (Very Large Telescope) is the world\'s largest telescope and is taking astronomers further back to the Big Bang than they ever thought possible. Located 2,600 meters up to the Chilean Andes, it has four huge mirrors, each about the size of a London bus. The VLT is so powerful it can spot a burning match 10, 000 kilometers away. 2 This astonishing power will allow astronomers to see events in space from the birth of stars to the collision of galaxies on the edge of the cosmos. The VLT is giving astronomers their best ever view of the cosmos. The power of the VLT to see the smallest detail at the furthest distances makes its designers amazed. 3 Take the case of Eta Carinae, one of the most explosive stars in the universe. This star produces ultraviolet laser rays (紫外线) and it will destroy itself in a few million years\' time. It is five times brighter than the sun and when it explodes it is going to be a sight worth waiting for. 4 But it is at distances of millions, even billions, of light years that the VLT really shows its power. The VLT can detect light that setout on its journey before the earth even existed. This gives astronomers their first ever detailed views of events that took place in the earliest days of the cosmos. 5 In other words, the VLT is a kind of a time machine. It takes astronomers back to a time when complete galaxies crashed into each other. The effects of these past collisions can now be seen by scientists, and astronomers believe the telescope will reveal more about these exciting events in the years to come. One day, we might be able to say we have traveled back to the beginning of time, and we will have a much clearer picture of how our planet was born. The designers of the VLT are surprised at____. 【单选题】
A.its detecting power
B.millions of light years away in space
C.the location of the VLT
D.as an example
E.the birth of the earth
F.the rotation of the earth
正确答案:A
答案解析:文章第2段最后一句也概括提到了这句话的意思。
9、The Value of AdvertisementMoney spent on advertising is worth spending. It serves directly to bring about a rapid sale of goods at reasonable prices, so setting up a firm home market and making it possible to provide forexport at good price. By drawing attention to new ideas it helps greatly to raise standards of living. By helping to increase demand it causes an increased need forlabor, and is therefore a nice way to fight unemployment. It lowers the costs of many services: without advertisements your daily newspaper would cost four times as much, the price of your television program would need to be doubled, and travel by bus orsubway would cost more. and perhaps most important of all, advertising provides a promise of reasonable value in the products and services you buy. Besides the fact that twenty-seven Acts of Parliament govern the terms of advertising, no regular advertiser dare produce anything that fails to live up to the promise of his advertisements. He might fool some people fora little while through misleading advertising. He will not do so forlong, forthe public has the good sense not to buy the poorgoods more than once. If you see a product frequently advertised, it is the proof I know that the product does what is promised forit, and that it has good value. Advertising does more forthe good of the public than any other force I can think of. There is one more point I feel I ought to touch on. Recently I heard a well-known television person declare that he was against advertising because it persuades rather than informs. He was telling us the real difference. Of course advertising tries to persuade. If its messages were nothing but information, that would be difficult to get more people to buy, foreven the choice of the colorof a shirt is a bit persuasive-advertising would be so boring that no one would pay any attention. But perhaps that is what the well-known television person wants.Which of the following is the most important advantage according to the passage?【单选题】
A.Reducing the cost of your daily newspaper.
B.Lowering the price of your television program.
C.Making it possible to provide forexport at good price.
D.Providing a promise of reasonable value in the products and services you buy.
正确答案:D
答案解析:选项A、B、C、D都是提到的好处,但是从文章第2段第1句可知,最重要的是广告能提供产品和服务的价值承诺。因此选D。
10、Weaving with LightIn the Sierra Madre mountain range of west central Mexico, the native Huichol people live much the way their ancestors did-without electricity. That\'s because it\'s too expensive to string power lines to the remote mountain areas where they live. To help support themselves, the Huichol create beautiful artwork. They sell their art in cities hundreds of miles away from their villages. and without electricity, at home oron the road, they can only work during daylight hours. When it gets dark, they must stop whatever they\'re doing.Now, a team of scientists, designers and architects is using new technologies to provide the Huichol with light after the sun sets. The scientists technique involves weaving tiny electronic crystals into fabrics that can be made into clothes, bags, orother items.By collecting the sun\'s energy during the day, these lightweight fabrics provide bright white light at night. Their inventors have named the fabrics "Portable Lights," Portable Lights have the potential to transform the lives of people without electricity around the world, says project leader Sheila Kennedy."Our invention," Kennedy says, "came from seeing how we could transform technology we saw every day in the United States and move it into new markets forpeople who didn\'t have a lot of money."At the core of Portable Light technology are devices called high - brightness light - emitting diodes, orHB LEDs. These tiny lights appear in digital clocks, televisions and streetlights.LEDs are completely different from the light bulbs. Most of those glass bulbs belong to a type called incandescent lights. Inside, electricity heats a metal coil to about 2,200 degrees Celsius. At that temperature, bulbs give off light we can see.Ninety percent of energy produced by incandescent lights, however, is heat and invisible. With all that wasted energy, bulbs burn out quickly. They are also easily broken.LEDs, on the other hand, are like tiny pieces of rock made up of molecules that are arranged in a crystal structure. When an electric current passes through an LED, the crystal structure produces light. Unlike incandescent bulbs, they can produce light of various colors. Within an LED, the type of molecules and their particular arrangement determines what coloris produced.LEDs are different from light bulbs in that ______.【单选题】
A.LEDs are made up to tiny pieces of rock
B.LEDs can send out light of different colors
C.LEDs belong to incandescent lights
D.LEDs look like crystals
正确答案:B
答案解析:本题有一定难度,关键在吃透句意,答案依据比较明显,带着题干信息词回文章定位,答案依据主要在文章最后一段第三句:Unlike incandescent bulbs,they can produce light of various colors.回来看选项,D项和原文句意相符,答案是B。
