2、Light Night, Dark StarsThousands of people around the globe step outside to gaze at their night sky. On a clear night, with no clouds, moonlight, or artificial lights to block the view, people can see more than 14,000 stars in the sky, says Dennis Ward, an astronomer(天文学家) with the University Corporation for Atmospheric Research( UCAR) in Boulder, Colo. But when people are surrounded by city lights, he says, they're lucky to see 150 stars. If you've ever driven toward a big city at night and seen its glow from a great distance, you've witnessed light pollution. It occurs when light from streetlights, office buildings, signs, and other sources streams into space and illuminates (照亮) the night sky. This haze (朦胧) of light makes many stars invisible to people on Earth. Even at night, big cities like New York glow from light pollution, making stargazing difficult.Dust and particles of pollution factories and industries worsen the effects of light pollution. "If one city has a lot more light pollution than another," Ward says, "that city will suffer the effects of light pollution on a much greater scale."Hazy skies also make it far more difficult for astronomers to dotheir jobs.Cities are getting larger. Suburbs are growing in once dark, rural areas. Light from all this new development is increasingly obscuring (使变模糊) the faint (微弱的) light give off by distant stars. And if scientists can't locate these objects, they can't learn more about them.Light pollution doesn't only affect star visibility. It can harm wild life too. It's clear that artificial light can attract animals, making them go off course. There's increasing evidence, for example, that migrating (迁徙) birds use sunsets and sunrises to help find their way, says Sydney Gauthreaux Jr. , a scientist at Clemson University in South Carolina, "When light occurs at night," he says, "it has a very disruptive (破坏性的) influence." Sometimes birds fly into lighted towers, high - rises, and cables from radio and television towers. Experts estimate that millions of birds die this way every year.On a clear night, people can see ______.【单选题】A.150 starsB.hundreds of starsC.one thousand starsD.more than 14,000 stars正确答案:D答案解析:本题难度不大，答案依据比较明显，在文章第一段第二句，这句话主要谈到，在晴朗的夜晚人们能看到14，000多颗星星，回来看选项，D项符合原文句意，是答案。

2、The Threat to KiribatiThe people of Kiribati are afraid that one day in the not-too-distant future, their country will disappear from the face of the earth-literally. Several times this year, the Pacific island nation has been flooded by a sudden high tide. These tides, which swept across the island and destroyed houses, came when there was neither wind nor rain. "This never happened before," say the older citizens of Kiribati.What is causing these mysterious high tides? The answer may well be global warming. When fuels like oil and coal are being burned, pollutants (污染物) are released. These pollutants trap heat in the earth's atmosphere. Warmer temperatures cause water to expand and also create more water by melting glaciers (冰川) and polar (极地的) ice caps.If the trend continues, scientists say, many countries will suffer, Bangladesh, for example, might lose one-fifth of its land. The coral (珊瑚) island nations of the Pacific, like Kiribati and the Marshall Islands, however, would face an even worse fate-they would be swallowed by the sea. The loss of these coral islands would be everyone's loss. Coral formations are home to more species than any other place on earth.The people of these nations feel frustrated. The sea, on which their economies have always been based, is suddenly threatening their existence. They don't have the money for expensive technological solutions like seawalls. And they have no control over the pollutants, which are being released mainly by activities in large industrialized countries. All they can do is to hope that industrialized countries will take steps to reduce pollution.High tides used to attack Kiribati when there was strong wind orheavy rain.【单选题】A.RightB.WrongC.Not mentioned正确答案:A答案解析:题干大意：当风强雨大的时候，高潮经常袭击基里巴斯。

2、AirbusDespite bulging order books, the mood at Airbus and Boeing is far from celebratory. Both aviation giants are moaning loudly that their production systems and supply chains are flawed, albeit for ostensibly different reasons. This week Louis Gallois, the boss of EADS, the Franco-German aerospace consortium that owns Airbus, added substance to warnings a week earlier by the planemaker’s chief executive, Tom Enders, that thedollar's decline was "life-threatening" for the firm. Mr. Gallois said it was no longer just a possibility that Airbus would have to move a large part of its production to "the dollar zone" or low-cost countries, but a certainty.Airbus is already in the middle of Power 8, a big restructuring plan that involves the loss of 10,000 jobs and the sale of several plants, which is meant to offset the losses caused by the delays in delivering the A380 superjumbo. But Power 8 assumed that a euro was worth $ 1.35, not today's $ 1.47. Mr. Gallois estimates that each 10-cent rise in the euro costs Airbus 1 billion. At present, Airbus makes 76% of its purchases within Europe, but generates over 60% of its sales elsewhere. It must now shift some production abroad.Airbus is now likely to forge ahead much further. Mr. Gallois suggests that when the A350 enters service in 2013, 70% of it will have been "purchased" in dollars, against 50% for the A380 and an average 24% of Airbus production today. Because Airbus insists that some of its European suppliers price in dollars that means about 50% of the A350's production will be outsourced. New aircraft, such as the A320's successor, may be made almost entirely outside the euro-zone.Airbus maintains that exchange rates are not the only reason for outsourcing: it is keen to tap into composite-manufacturingexpertise wherever it exists. It also insists that it will not repeat the mistakes Boeing has made with its new 787 Dreamliner, about 80% of which has been outsourced. A few weeks ago Mike Bair, the executive responsible for the 787 programme, who was recently moved sideways after mounting production delays, launched a withering attack on some of the companies recruited to build the plane. He said that in future Boeing would not entrust design work to partners who "proved incapable of doing it", and would make suppliers build factories close to Boeing's main assembly operation, rather than flying semi-finished sections of the aircraft round the world on huge Dreamlifter transporters.It is too early to conclude that the two rivals are heading in opposite directions- Boeing renouncing the global supply chain just as Airbus adopts it. Each company has its own axe to grind. Airbus needs greater flexibility, and the weak dollar provides helpful cover as it takes on its grumbling unions. Boeing, for its part, wants to shift the blame for delays to the 787 on to its partners. The logic of global outsourcing in the aerospace industry remains powerful. Whatever they may be saying now. Airbus and Boeing are more likely to converge than to diverge. The word "converge" (line 7, paragraph 5) most probably means ______.【单选题】A.unitebineC.meetD.cooperate正确答案:C答案解析:猜词题。

职称英语考试《理工类》模拟试题及答案0510-1021、Breastfeeding Can Cut Cardiovascular Risk Breastfeeding can reduce the risk of a heart attack or stroke later in life and could prevent hundreds of ______ 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 for stroke and heart attack." said Professor Alan Lucas of the Institute of Child Health in London."Our evidence suggests that the reason why breast-fed babiesdo 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 for cardiovascular 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 or given different nutritional baby formulas' They reported their findings 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 for cardiovascular 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 for both 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.hundredsB.thousandslionsD.numbers正确答案:B答案解析:hundreds ofthousands of是固定搭配，表示“成千上万”之意。

职称英语考试《理工类》模拟试题及答案0510-1301、Inventor of LEDWhen Nick Holonyak set out to create a new kind of visible lighting using semiconductor alloys, his colleagues thought he was unrealistic. Today, his discovery of light-emitting diodes, or LEDs, are used in everything from DVDs to alarm clocks to airports. Dozens of his students have continued his work, developing lighting used in traffic lights and other everyday technology.On April 23,2004, Holonyak received the $500,000 Lemelson-MIT Prize at a ceremony in Washington. This marks the lOth year that the Lemelson-MIT Program at the Massachusetts Institute of Technology (MIT) has given the award to prominent inventors. "Anytime you get an award big or little. It＇s always a surprise. " Holonyrak said. Holonyak, 75, was a student of john Bardeen, an inventor of the transistor, in the early 1950s. After graduate school, Holonyak worked at Ben Labs. He later went to General Electric, where he invented a switch now widely used in house dimmer switches.Later, Holonyak started looking into how semiconductors could be used to generate light. But while his colleagues were looking at how to generate invisible light, he wanted to generate visible light. The LEDS he invented in 1962 now last about 10 times longer than incandescent bulbs, and are more environmentally friendly and effective.Holonyak, now a professor of electrical and computer engineering and physics at the University of Illinois, said he suspected that LEDs would become as commonplace as they are today, but didn＇t realize how many uses they would have. "You don＇t know in the beginning. You think you＇re doing something important. You think it＇s worth doing, but you really can＇t tell what the big payoff is going to be, and when, and how. You just don＇t know, "he said.The Lemelson. MIT Program also recognized Edith Flanigen, 75, with the $100,000 Lemelson-MIT Lifetime Achievement Award for her work on a new generation of "molecular sieves", that can separate molecules by size.Holonyak believed that LEDs would become very popular in the future.【单选题】A.RightB.WrongC.Not mentioned正确答案:A答案解析:题干中出现的核心词popular作为答案线索，文章中并没有出现popular这个词。

The first prehensive study on the nation's oral health，released recently by the Office of the U.S. Surgeon General，calls dental and oral diseases a “silent epidemic (流行病)，” even in children. The report states that more than 51 million school hours are lost each year to dental-related illness. In fact，a recent study pointed to dental care as the most mon unmet health need among American children.To help counter this，the American Academy of Periodontology (牙周病学)(AAP)is launching an effort to educate children and parents about the prevention of dental diseases in children.“This is important because oral problems can impactself-esteem for children and lead to problems of eating，speaking and attending to learning，” said Michael McGuire，president of the AAP.Common dental problems seen in children are cavities(龋洞)and gingivitis (龈牙)，which are found in themajority of U.S. children. “When these problems are not caught early and treated，they can develop into more severeproblems and cause unnecessary suffering，” said McGuire “Ho wever，much of the time，oral problems are avoidable problems.”In the Rio Grande Valley in Texas，a group of more than 120 dentists volunteers to deliver dental care to thousands of low-ine children each year with its Mobile Dental Unit that travels from school to school.“Aording to the Surgeon General's Report，about 37 percent of children have not had a dental visit before starting school，” said McGuire. “When children don't see dentists they miss the opportunity to have problems caught early before they develop into larger，more expensive problems to treat，and parents miss the opportunity to learn how to promote good oral habits in their children.”16 Only in February should attention be paid tochildren's oral healthA RightB WrongC Not mentioned17 Dental and oral diseases are mon in both adults and childrenA RightB WrongC Not mentioned18 Boys miss more school hours each year due to dental-related illnessA RightB WrongC Not mentioned19 Oral problems in children can develop into more severe problems.A RightB WrongC Not mentioned20 Oral problems can not be avoided in any wayA RightB WrongC Not mentioned21 The low-ine children are very grateful to the dentists.A RightB WrongC Not mentioned22 Some children have never seen a dentist before starting school.A RightB WrongC Not mentionedUnderstanding Autism1 Autism (孤独症)is a life-long developmentaldisability that prevents individuals from properly understanding what they see，hear，and otherwise sense. This results in severe problems of social relationships，munication，and behavior. Individuals with autism have to painstakingly '(费力地)learn normal patterns of speech and munication，and appropriate ways to relate to people，objects，and events，in a similar manner to those who have had a stroke.2 The cause of autism is still unknown. Some research suggests a physical problem affecting those parts of the brain that process language and information ing in from the senses. There may be some imbalance of certain chemicals in the brain. Geic (遗传的)factors may sometimes be involved.Autism may indeed result from a bination of several “causes”。

Around the world, people are starting to measure the effects of global warming - and trying to figure out what to do about it.Scientists recently used satellites to study the temperatures of lakes around the world, and they found that lakes are heating up.Between 1985 and , satellites recordedthe nighttime temperatures of the surfaces of 167 lakes. During those 24 years, the lakes got warmer - by an average of about 0.045 degree Celsius per year.In some places, lakes have been warming by as much as 0.10 degree Celsius per year. At that rate, a lake may warm by a full degree Celsius, or 1.8 degrees Fahrenheit, in just 10 years. That difference may seem small - you might not even notice it in your bathtub. But in a lake, slightly warmer temperatures could mean more algae, and algae can make the lake poisonous to fish.The study shows that in some regions, lakes are warming faster than the air around them. This is important because scientists often use measurements of air temperature to study how the Earth is warming. By using lake temperatures as well, scientists can get a better picture of global warming.The scientists say data on lakes give scientists a new way to measure the impact of climate change around the world.That's going to be useful, since no country is too big or too small to ignore climate change. Scientists aren't the only ones concerned. Everyone who lives on Earth is going to be affected by therapidwarming of the planet.Many world leaders believe we might be able to do something about it, especially by reducing the amount of greenhouse gases we put into the air.That's why the United Nations started the Framework Convention on Climate Change, or UNFCCC. Every year the convention meets, and representatives from countries around the world gather to talk about climate change and discuss global solutions to the challenges of a warming world.16 Scientist have been keeping records of lake temperatures for over 30 years.A RightB WrongC Not mentioned17 The temperatures of lakes around the world have increased greatly between 1985 and .A RightB WrongC Not mentioned18 Lakes seem to be warming faster in Asia.A RightB WrongC Not mentioned19 A slight temperature increase in a lake could be harmful to fish.A RightB WrongC Not mentioned20 Scientists generally focus on air temperatures when studying global warming.A RightB WrongC Not mentioned21 Globle warming is less threatening to small countries.A RightB WrongC Not mentioned22 UNFCCC's annual meeting will be held in Mexico this year.A RightB WrongC Not mentioned第3部分：概括大意与完成句子（第23～30题，每题1分，共8分）下面的短文后有2项测试任务：（1）第23～26题要求从所给的6个选项中为第2～5段每段选择1个最佳标题；（2）第27～30题要求从所给的6个选项中为每个句子确定一个最佳选项。

职称英语考试《理工类》模拟试题及答案0510-491、Walking to Exercise the BrainDo you think sitting and studying all the time will improve students grades? Think again. Getting some exercise may help, too.New research with older people suggests that taking regular walks helps them pay attention better than if they didn't exercise.Previous research had shown that mice learn, remember and pay attention better after a few weeks of working out on a running wheel. Mice that exercise have greater blood flow to the brain than those who don't. Their brain cells also make more connections.Neuroscientists (神经科学家) from the University of Illinois at Urbana Champaign wanted to find out if the same thing is true for people. First, they measured the physical fitness of 41 adults, ages 58 to 77, after each person walked I mile. Then, participants looked at arrows on a computer screen and had touse computer keys to show which way one particular arrow was pointing.Adults who were physically fit were faster at the arrow task, and their answers were just as accurate as their less - fit peers, the researchers found. The fitter participants also had more blood flow to a part of their brain responsible for paying attention and making decisions.In a second study, 15 elderly people who completed a 6 - month aerobic - training (有氧运动) course were faster at attention tasks compared with 14 seniors who just did stretching and toning (韵律操) exercises for the same amount of time.So, even going for a walk every 2 or 3 days for just 10 to 45 minutes can help. That should be good news for the elderly. The effects of exercising on the brains of younger people haven't been studied yet. Still, it can't hurt to take occasional breaks and go for a walk or run around with friends. Whatever you do, though, don't try to read and walk at the same time. You could end up hurting yourself!It can be good for health when one takes a walk every 2 or 3 days for at least ______.【单选题】A.3 minutesB.45 minutesC.30 minutesD.10 minutes正确答案:D答案解析:本题有一定难度，需要认真阅读文章。

2、How to Be a Successful BusinesspersonHave you ever wondered why some people are successful in business and others are not? Here's a story about one successful businessperson. He started out washing dishes and today he owns 168 restaurants.Zubair Kazi was born in Bhatkal, a small town in southwest India. His dream was to be an airplane pilot, and when he was 16 years old, he learned to fly a small plane.At the age of 23 and with just a little money in his pocket, Mr. Kazi moved to the United States. He hoped to get a job in the airplane industry in California. Instead, he ended up working for a company that rented cars.While Mr. Kazi was working at the car rental(租赁的) company, he frequently ate at a nearby KFC restaurant. To save money on food, he decided to get a job with KFC. For two months, he worked as a cook's assistant. His job was to clean the kitchenand help the cook. "I didn't like it," Mr. Kazi says, "but I always did the best I could."One day, Mr. Kazi's two co -workers failed to come to work. That day, Mr. Kazi did the work of all three people in the kitchen. This really impressed the owners of the restaurant.A few months later, the owners needed a manager for a new restaurant. They gave the job to Mr. Kazi. He worked hard as the manager and soon the restaurant was making a profit.A few years later, Mr. Kazi heard about a restaurant that was losing money. The restaurant was dirty inside and the food was terrible. Mr. Kazi borrowed money from a bank and bought the restaurant. For the first six months, Mr. Kazi worked in the restaurant from 8 a. m. to 10 p. m. , seven days a week. He and his wife cleaned up the restaurant, remodeled the front of the building, and improved the cooking. They also tried hard to please the customers. If someone had to wait more than ten minutes for their food, Mrs. Kazi gave them a free soda. Before long the restaurant was making a profit.A year later, Mr. Kazi sold his restaurant for a profit. With the money he earned, he bought three more restaurants that were losing money. Again, he cleaned them up, improved the food, and retrained the employees. Before long these restaurants were making a profit, too.Today Mr. Kazi owns 168 restaurants, but he isn't planning to stop there. He's looking for more poorly managed restaurants to buy. "I love it when I go to buy a restaurant and find it's a mess," Mr. Kazi says. "The only way it can go is up. "Mr. Kazi decided to work with KFC to ______.【单选题】A.learn how to cookB.save money for a carC.save money on foodD.learn how to run a restaurant正确答案:C答案解析:本题难度不大，也是送分题，答案依据是这一句：To save money on food，he decided to get a job with KFC.3、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 for blind people in Sommerset and a resource centre for the 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 ______ 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 door without a sound alarm, but only 15 seconds with one. Withington studies how the brain processes sounds at the university. She says that the source of a wide band of frequencies can be pinpointed more easily than the source of anarrow band. Alarms basedon the same concept have already been installed on emergency vehicles.The alarms will also include rising or falling frequencies to indicate whether people should go up or down stairs. They were developed with the aid of a large grant from British Nuclear Fuels.【单选题】A.watchedB.producedC.learntD.heard正确答案:D答案解析:文章一直在讨论警报器、声音，因此很容易推断应该是被人听到。

3、What Do Dreams Tell Us?Why do we dream? Do dreams have meanings? These are questions which have troubled man for thousands of years. The oldest surviving book on the interpretation of dreams is Egyptian and is nearly 4,000 years old. In ancient Greece, it was thought that people who were ill could be cured by telling their dreams. They would relate their dreams to their doctors who would tell them what they meant and then give them medicine to make them well. The ancient Chinese believed that if a pregnant woman dreamed of a bear, she would have a son, and if she dreamed of a snake, she would have a daughter. There are many stories about dreams foretelling (预言) the future.We certainly do not now believe that dreams foretell the future. Most scientists believe that dreams are based on events in our own life and on our feelings. The events are usually very recent, mostly within the last two days. Our emotions, on the other hand our wishes, hopes and fears may go back many years, even to early childhood.In a dream, events are altered. A dream may contain parts of many real-life events. Most importantly, something that cannot be shown directly may be shown indirectly. For example, you might dream of driving a large car. This could mean not that you want to have a larger car, but that you desire power, and maybe you want to control other people. Again, you may dream thatyou are an actor in a play. The play is about to start, but you have completely forgot your lines. This dream may seem strange because you are not interested in acting, and you never want to be in a play. But the dream may mean that you have some other problem that you feel is too difficult for you to solve.Psychologists believe that dreams may be helpful to us. Indeed, people who have been allowed to sleep in experiments, but not allowed to dream, have become anxious and restless. And when they are later allowed to sleep as much as they like, they dream more than ever to make us for the lost "dream time". Paragraph 3 ______.【单选题】A.Structure and interpretation of a dreamB.Ancient views on dreamsC.Babies dream less than older childrenD.Dreaming may be good for our healthE.Dreams can not foretell the futureF.Healthy people do not dream正确答案:A答案解析:第三段主题句为第一句：In a dream，events are altered. 梦中发生的事是不断变换着的。
其所隐含的意义也不同。
A选项Structure and interpretation of a dream（梦的结构与阐释）与其意思相符，故A为正确答案。
4、One Good Reason to Let Smallpox LiveIt's now a fair bet that we will never see the total extinction (灭绝) of the smallpox (天花) virus. When smallpox was completely got rid of in the world, scientists wanted to destroythe killer virus in the last two labs, one in the US and one in Russia. They asked: If smallpox has truly gone from the planet, what point was there in keeping these reserves?In reality, of course, it was naive to imagine that everyone would let go of such a powerful potential weapon. Undoubtedly several nations still have a few vials (小药瓶). And the last "official" stocks of live Virus bred mistrust of the US and Russia, for no obvious gain.Now American researchers have found an animal model of the human disease, opening the way for tests on new treatments and vaccines(疫苗). So once again there's a good reason to the virus, just in keep the disease puts in a reappearance.How do we case with the mistrust of the US and Russia? deal. Keep the virus _____ international support in a well - guarded UN laboratory that's open to all countries. The US will object, of course, just as it with a multilateral (多边的) approach to just about everything. But it doesn't mean the idea is rejects. If the virus is useful, then let's wrong it the servant of all humanity make not just a part of it.【单选题】A.SimpleB.OpenC.SafeD.Possible正确答案:A答案解析:本题有一定难度，需要理解好上下文意义，文章此处是说“我们怎样应对美国和俄罗斯的不信任呢？很简单……”答案是A。
5、Seeing Red Means Danger AheadThe color red often means danger and by paying attention, accidents can be prevented. In the future, the color red also may help prevent danger at construction sites. Thanks to newwork by engineers, bridge supports or other kinds of materials, could one day contain a color -changing material. It will turn red before a structure collapses or falls apart.The secret behind the color - changing material is a particular type of molecule (分子). A molecule is a group of atoms (原子) held together by chemical bonds. Molecules come in all shapes and sizes and make up everything you can see, touch or feel. How a molecule behaves depends on what kinds of atoms it contains and how they're held together.When a polymer (聚合物) containing a color -changing molecule called a mechanophore (机械响应性聚合物) is about to break, it produces a color. When a polymer with mechanophore molecules becomes "injured" or weak, one of the mechanophore bonds breaks and the material turns red. "It's a really simple detection method," says Nancy Sottos, one of the scientists who worked on the project. Sottos and her team tested the color - changing polymers in their lab. The test results proved encouraging.There is a way to get rid of the red color light. When a bright light is shone on the mechanophore, the broken bond is fixed and the red color disappears. Thus "self -healing" may be a problem for engineers. They need to use the color - changer inbig construction projects that will be outside, under sunlight. And sunlight will make the mechanophore's warning system useless.Sottos and her fellow scientists still have _____ work to do before the color - changing molecules can be used outside the lab.【单选题】A.a pair ofB.a type ofC.a lot ofD.a part of正确答案:C答案解析:本题难度不大，考查词义辨析。
