Eastern Quakes Can Trigger Big ShakesIn the first week of November 2011, people in central Oklahoma experienced more than two dozen earthquakes. The largest, a magnitude 5.6 quake, shook thousands of fans in a college football stadium, caused cracks in a few buildings and rattled the nerves of many people who had never felt a quake before. Oklahoma is not an area of the country famous for its quakes. If you watch the news on TV, you see reports about all sorts of natural disasters —hurricanes, tornadoes, flooding and wildfires, to name a few. But the most dangerous type of natural disaster, and also the most unpredictable, is the earthquake.Researchers at the U.S. Geological Survey estimate that several million earthquakes rattle the globe each year. That may sound scary, but people don’t feel many of the tremors because they happen in remote and unpopulated regions. Many quakes happen under the ocean, and others have a very small magnitude, or shaking intensity.A magnitude 5.8 earthquake that struck central Virginia the afternoon of August 23, 2011, was felt from central Georgia to southeastern Canada. In many urban areas, including Washington, D.C., and New York City (Wall Street shown), people crowded the streets while engineers inspected buildings. Credit: Wikimedia/Alex TabakScientists know about small, remote quakes only because ofvery sensitive electronic devices called seismometers. These devices detect and measure the size of ground vibrations produced by earthquakes. Altogether, USGS researchers use seismometers to identify and locate about 20,000 earthquakes each year.Although earthquakes can happen anywhere in the world, really big quakes occur only in certain areas. The largest ones register a magnitude 8 or higher and happen, on average, only once each year. Such big ones typically occur along the edges of Earth’s tectonic plates.Tectonic plates are huge pieces of Earth’s crust, sometimes many kilometers thick. These plates cover our planet’s surface like a jigsaw puzzle. Often, jagged edges of these plates temporarily lock together. When plates jostle and scrape past each other earthquakes occur. On average, tectonic plates move very slowly — about the same speed as your fingernails grow.But sometimes earthquakes rumble through portions of the landscape far from a plate’s edges. Although les s expected, these “mid-plate” tremors can do substantial damage. Some of the biggest known examples rattled the eastern half of the United States two centuries ago. Today, scientists are still puzzling over why the quakes occurred and when similar ones might occur.16. Oklahoma is an area often experiencing natural disasters.A. RightB. WrongC.

职称英语考试理工类(C级)试题及答案(5)第三篇Computers in CarsYou're far from home on a lonely road.Shadowy forests stretch away on both sides.Athick mist(雾)makes it difficult to see far beyond your car's windshield (挡风玻璃)."Can this be route 90A?"you wonder.If it is ,you should be near a town.Yet there's no hint of one. Night is closingin.And you're low on gasoline.This is a situation where an in -car computer that can navigate would be a big help.A car computer that navigates?Yes!Such computers exist . Several experimental models are being tested by General Motors,Ford,Chrysler,and several foreign car makers.These computers vary in detail. But they all contain series of maps on videodiscs or videotapes.For example,one computer system contains 13,300 maps covering the continental US.Before starting out on a trip,a driver can type in the code for the region he or she plans to drive through.The computer then shows a map of theat region.At the same time,a tiny radio receiver linked to the computer goes to work. It picksup signals from navigation satellites such as the NAVSTAR ing these signals,the computer shows the car's position at all times and displays this position on the map.The computer can dalso calculate and display the best route to follow.A navigation computer may also receive and use data about road construction, weather conditions,and traffic jams.This information would be displayed to the driver and the computer would also use the information to work out alternate(交替的)routes.Most cars nowadays also contain computers that help cars run more efficiently. Microprocessors(微处理机)control certain engine functions by regulating the mixing of fuel.Data on car speed,oil pressure,revolutions per minute,enginete mperature , and fuel level can be displayed as digital data (numbers) or warning lights.Some auto designers suggest that a central computer display be used to clearly present such timely information as car speed and fuel level.Warning lights would indicate a drop in oil pressure or a sudden rise in engine temperature.To get more information on these conditions,the driver could call it up on the computer display screen.When needed,the computercould be "asked"to provide navigation aid or information about the car's condition.41 By describing a typical situation of a lost driver on the road,the arthor intends toA make us believe how complex the highway computer network is.B let us know how in-car computers are linked to road signs.C show us how helpful a navigation computer can be.D tell us that NAVSTAR has come into use.42 The word "navigate"in Paragraph 3 meadnsA "help one comtrol the traffic".B "help one find one's way".C "give a ship correct information about its course".D "direct a plande to its destination."43 The dnavigation computers have one thing in common:they allA contain series of maps on videodisce or videotapes.B contain 13,300 maps covering the continentalUS.C can be obtained free of charge.D cost a lot of money.44 Without signals from navigation satellites,the in-carcomputerA would still be able to locate the car's position at all times.B would fail to locate the car's position.C could still work out the best route to follow.D would seek help from the radio receiver linked to it .45 Of the following functions,which is NOT possessed by the navigation computer?A Showing a map of the region a driver plans to drive through.B Predicting a car crash on the road.C Getting information about roadconstruction,weather conditions,and traffic jams.D Showing the car's position at all times and displaying it on the map.【备注说明，非正文，实际使用可删除如下部分。

以下是理工类阅读部分真题及详解!试题The Development of BalletBallet is a dance form that has a long history. The fact that it survives to this day shows that it has adjusted as times have changed.Ballet began in the royal courts during the Renaissance. At that time it became common for kings and queens，as well as other nobility，to participate in pageants that included music，poetry，and dance. As these entertainments moved from the Italian courts to the French ones，court ladies began participating in them. Though their long dresses prevented much movement，they were able to perform elaborate walking patterns. It was not until the 1600s that women dancers shortened their skirts，changed to flat shoes，and began doing some of the leaps and turns performed by men.It was also in the 1600s that professional ballet began. King Louis XIV of France，himself a devoted dancer，founded the Royal Academy of Dance. The five basic feet positions from which all ballet steps begin were finalized. In the late 1700s another important change occurred. Ballet began to tell a story on its own. It was no longer simply dance to be performed between acts of plays. Elaborate wigs and costumes were eliminated. By the early 1800s dancers learned to rise on their toes to make it appear that they were floating.Classical ballet as we know it today was influenced primarily by Russian dancing. The Russians remained interested in ballet when it declined in other European countries in the mid -1800s. One of the most influential figures of the early 20th century was Sergei Diaghilev. His dance company，the Ballets Russes，brought a new energy and excitement to ballet. One of his chief assistants，George Balanchine，went on tofound the New York City Ballet in 1948 and to influence new generations of dancers.词汇:adjust / ?' d??st/v. 调整 eliminate /i'limineit/ v. 淘汰pageant / 'pæd? ?nt / n. 盛会 influential / influ'en??l/adj. 有影响力的注释:1.

The first comprehensive 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 common 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 impact self-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 the majority of U.S. children. “When th ese problems are not caught early and treated，they can develop into more severe problems and cause unnecessary suffering，” said McGuire “However，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-income children each year with its Mobile Dental Unit that travels from school to school.“According 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 theydevelop 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 to children's oral healthA RightB WrongC Not mentioned17 Dental and oral diseases are common 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 mentioned21The low-income 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 mentioned。

以下是店铺精心为大家整理的理工类的2016年职称英语考试真题及答案，希望对大家有所帮助!更多内容请关注应届毕业生网!阅读理解大学生利用课余时间打工the future of pressCan you hear This?When something creates a sound wave in a room or an auditorium, listeners hear the sound wave directly from the source. They also hear the reflections as the sound bounces off the walls, floor, and ceiling. These are called the reflected wave or reverberant(反射的)sound, which can be heard even after the sound is no longer coming from the source.The reverberation time of an auditorium is determined by the volume or interior size of the auditorium. It is also determined by how well or how poorly the walls, ceiling, floor, and contents of the room (including the people) absorb sound. There is no ideal reverberation time. Because each use of an auditorium calls for different reverberation. Speech needs to be understood clearly: therefore rooms used for talking must have a short reverberation time. The full-sound performance of music such as Wagner operas or Mahler symphonies should have a long reverberation time. The light, rapid musical passages of Bach or Mozart need a reverberation time somewhere between.Acoustic problems often are caused by poor auditorium design. Smooth, curved reflecting surfaces create largereflections. Parallel(平行的)walls reflect sound back and forth, creating a rapid, repetitive pulsing effect. Large pillars(柱)and corners can cause acoustic shadows as the sound waves try to pass around the object. Some of these problems can be solved by using absorbers and reflectors to change the reverberation time of a room. For example, hanging large reflectors, called clouds, over the performers will allow some sound frequencies to reflect and others to pass to achieve a pleasing mixture of sound.41.【题干】This passage is mainly about_____A.sound waves and their effects.B.the types of music orchestras play.C.walls of an auditorium.D.the design of an auditorium.42.【题干】Wagner operas and Mahler symphonies with full-sound effect have_____A.a short reverberation time.B.an intermediate reverberation time.C.no reverberation time.D.a long reverberation time.43.【题干】This passage suggests that a good auditorium should_____A.get rid of all reflections.B.not have absorbers.C.achieve a pleasing mixture of sound.D.have smooth surfaces.44.【题干】Large pillars and corners may_____A.make sound rich and full.B.be cures for sound problems.C.be sources of sound problems.D.function as effectively as clouds.45.【题干】The word "acoustic" in the last paragraph has something to do with_____A.performance.B.sound.C.audience.D.weather.补全短文US Signs Global Tobacco Treaty【美国签订了全球烟草协议】The United States has taken the first step toward approving a global tobacco treaty that promises to help control the deadly effects of tobacco use throughout the world. Health and Human Services Secretary Tommy Thompson signed the Framework Convention on Tobacco Control (FCTC) this week at the United Nations. ____(46)The FCTC was developed by the World Health Organization and approved by members of the World Health Assembly，including the United States，last year. ______(47)For instance, cigarettes sold in those countries would have to have health warnings on at least 30% of the front and back of every pack. _____(48) It also requires bans on tobacco advertising, though there are some exceptions for countries like the United States, where the Constitution prohibits such an outright ban.______(49)The World Health Organization estimates that tobacco use kills nearly 5 million people worldwide every year. In the US alone, about 440,000 people die each year from tobacco-related illnesses; about one-third of all cancers in the US are caused by tobacco use. If current trends continue, WHO estimates, by 2025 tobacco will kill 10 million people each year.The treaty must be ratified by at least 40 countries before it can take effect. ______(50)A.Tobacco stocks also perked up as investors discounted fears of litigation(诉讼) from the USB. So far，109 countries have signed it, and 12 have ratified it.C. The impact of the treaty could be huge.D. Countries that ratify(批准) it would be required to enact strict tobacco control policies.E.The treaty calls for higher tobacco taxes, restrictions on smoking in public places, and more promotion of tobacco prevention and cessation programs.F. The Senate must still approve the treaty before the US can implement its provisions.完形填空Freezing to Death for BeautyPeople in Beijing wear a lot of clothing during winter to fend off the cold.

She researches how exposure to things in the environment affects children'shealth. In a new study , she and her team studied the exposureto air pollution of 233 nonsmoking pregnant women inNew York City. Because burning tobacco can spew(排放) PAHs into the air and lungs, Perera's team focused on nonsmokers.The researchers wanted to probe(探查) other sources of PAHs, ones that would have been hard for an individual to avoid.The team started by testing the blood of each womanduring pregnancy. The reason：Any PAHs in a woman's blood would also be available to the baby in her womb. Nine yearslater, the researchers investigated signs of attentionproblems in these children, now age 9. They asked eachchild's mother a series of questions. These included whetherher child had problems doing things that needed sustained(长期的 ) mental effort, such as homework or games with friends.The scientists also asked if the kids had trouble followinginstructions or made frequent, careless mistakes. All ofthese can be symptoms of a disorder called Attention Deficit Hyperactivity Disorder, or ADHD. About one in 10 U.S.children has ADHD.Among the women studied, traffic and home heating werethe primary sources of air pollution exposure, Perera and herteam suspect. Some of these women had low levels of PAHsin their blood. Others had high levels. Those with high levelswere five times as likely to have children who showed attention problems by age 9.

By using a technique called ion doping, the team of researchers have discovered a material that could use light to bring together different computing functions into one component, leading to all-optical systems.3)Computers currently use electrons to transfer information and process applications. On the other hand, data sources such as the internet rely on optical systems; the transfer of information using light. Optical fibres are usedto send information around the world at the speed of light,but these signals then have to be converted to electrical signal sonce they reach a computer, causing a significant slowdown in processing.4)"The challenge is to find a single material that can effectively use and control light to carry information arounda computer. Much like how the web uses light to deliver information, we want to use light to both deliver and process computer data," said project leader, Dr Richard Curry of the University of Surrey.5)"This has eluded researchers for decades, but now we have now shown how a widely used glass can be manipulated to conduct negative electrons, as well as positive charges, creating what are known as 'pn-junction' devices. This should enable the material to act as a light source, a light guideand a light detector - something that can carry and interpret optical information. In doing so, this could transform the computers of tomorrow, allowing them to effectively process information at much faster speeds."6)The researchers expect that the results of this research will be integrated into computers within ten years.In the short term, the glass is already being developed and used in next-generation computer memory technology known as CRAM, which may ultimately be integrated with the advances reported.23 Paragraph 2 _____24 Paragraph 3 _____25 Paragraph 4 _____26 Paragraph 5 _____A.

Does it increase blood pressure?Does it help you concentrate? However, coffee affectsthe health of the human population in other ways, too.Traditionally, coffee bushes were planted under thecanopy( 树冠 )of taller indigenous( 土生土长的 )trees. However, more and more farmers in Latin America are deforesting theland to grow full-sun coffees. At first, this increasesproduction because more coffee bushes can be planted if therearen ’t any trees. With increased production come increased profits.Unfortunately, deforesting for coffee production immediately decreases local-wildlife habitat. Native birdsnest and hide from predators( 捕食者 )in the tall trees and migrating birds rest there.Furthermore, in the long term, the full-sun method also damages the ecosystem because more chemical fertilizers and pesticides are needed to grow the coffee. The fertilizers and pesticides kill insects that eat coffee plant, but then thebirds eat the poisoned insects and also die. The chemicalskill or sicken other animals as well, and can even enter the water that people will eventually drink.Fortunately, farmers in Central and South America are beginning to grow more coffee bushes in the shade. Wecan support these farmers by buying coffee with such labels as "shade grown" and "bird friendly." Sure, these varieties might cost a little more. But we're paying for the health ofthe birds, the land, ourselves, and the planet. I think it'sworth it.31.What is the main idea of this passage?A. Farmers are changing the way they grow coffee.B. Coffee is becoming more expensive to produce.C. Shade-grow coffee is more expensive than sun-grow coffee.D. People should buy shade-grown coffee.32.The function of the word "Traditionally" in Paragraph 2 is to show_____.A. the positive effects of coffee.B. a change of coffee growth.C. something that is the most important.D. how coffee production used to be33.What does increased production of full-sun coffee bring about?A. More insects.B. Better quality coffee.C. Larger farms.D. Higher profits.34.How do farmers find more land for growing full-sun coffee?A. They buy more land from other farmers.B. They cut down trees.C. They move to another country.D. They turn grassland into farmland.35.The full-sun method may affect the following EXCEPT_____ full sunA.insects.B.air.C.birds.D.humansSoot( 煤烟灰 )and Snow： a Hot CombinationNew research from NASA scientists suggests emissionsof black soot after the way sunlight reflects off snow.According to a computer simulation, black soot may be responsible for 25 percent of observed global warmingover the past century.Soot in the higher latitudes(维度)of the Earth, where ice is more common, absorbs more of the sun's energy and warmth than an icy, white background. Dark-colored black carbon, or soot, absorbs sunlight, while lighter colored ice reflectssunlight.Soot in areas with snow and ice may play an importantrole in climate change. Also, if snow and ice covered areasbegin melting, the warming effect increase, as the sootbecomes more concentrated on the snow surface." This providesa positive feedback, as glaciers and ice sheets melt, theytend to get even dirtier." said Dr. James Hansen, aresearcher at NASA's Goddard Institute for Space Studies,New York.Hansen found soot's effect on snow albedo(反照率), which may be contributing to trends toward early springs in theNorthern Hemisphere, such as thinning Arctic sea ice andmelting glaciers permafrost. Soot also is believed to play a rolein changes in the atmosphere above the oceans and land."Black carbon reduces the amount of energy reflected bysnow back into space, thus heading the snow surface more thanif there were no black carbon, " Hansen said. Soot's increased absorption of solar energy is especially effectivein warming the world's climate." This forcing is unusuallyeffective, causing twice as much global warming as a carbon-dioxide forcing of the same magnitude." Hansen noted.Hansen cautioned, although the role of soot in alteringglobal climate is substantial, it does not alter the factthat greenhouse gases are the primary cause of climatewarming during the past century. Such gases are expected tobi the largest climate forcing for the rest of the century.The researchers found that observed warming in theNorthern Hermisphere was large in the winter and spring atmiddle and high latitudes. These observations were coherentwith the researchers' climate model situations, which showedsome of the largest warming effects occurred when therewere heavy snow cover and sufficient sunlight.36.Which of the following statements of soot is NOT true?A. It absorbs sun's heat.B. It is responsible for climate change.C. It reflects sunlight.D. It may account for a quarter of global warming over the past century.37.Which of the following areas shows a greater warming effect?A. Ice sea areas.B. Areas with black carbon.C. Areas covered with white snow.D. Melting glaciers.38."This forcing" in Paragraph 5 refers to?A. sun's heating on snow surface.B. soot's increased absorption of solar energy.C. carbon-dioxide's warming effect.D. snow's increased reflection of sunlight.39.What is the main cause of climate warming duringthe past century?A.Soot.B.Snow.C.Greenhouse gases.D.Wind.40.The largest warming effects happened in the Northern Hemisphere withA. X sea ice and insufficient sunlight.B. light snow cover and sufficient sunlight.C. heavy snow cover and sufficient sunlight.D. thick sea ice and insufficient sunlight.A record-breaking powerA Record-Breaking RoverNASA’s Mars rover Opportunity has boldly gone where no rover has gone before —at least in terms of distance. Since arriving on the Red Planet in 2004, Opportunity has traveled 25.01 miles, more than any other wheeled vehicle has on another world.On July 27, after years of moving about on Martian ground, the golf-cart-sized Opportunity had driven more than 24 miles, beating the previous record holder —a Soviet rover sent to the moon in 1973.“This is so remarkable considering Opportunity was intended to drive about 1 kilometer and was never designed for distance, 〞 says John Callas, the Mars Exploration Rover Project Manager.He works at NASA ’s Jet Propulsion Laboratory in Pasadena, Cali fornia. “But what is really importantly is not how manymiles the rover has racked up, but how much exploration and discovery we have accomplished over that distance.〞OPPORTUNITYThe solar-powered Opportunity and its twin rover, Spirit,landed on Mars 10 years ago on a mission expected to last3 months. The objective of the rovers was to help scientistslearn more about the planet and to search for signs of life ， such as the possible presence of water.Spirit stopped communicating with Earth in March 2021, afew months after it got stuck in a sand pit. But Opportunity has continued to collect and analyze Martian soil and rocks.During its mission, Opportunity has captured, and sent backto Earth, some 187,000 panoramic and microscopic images ofMars with its cameras. It has also provided scientistswith data on the planet ’s atmosphere, soil, rocks, andterrain.MARATHON ROVERThe rover doesn ’t seem to be ready to stop just yet. If Opportunity can continue on, it will reach another majorinvestigation site when its odometer hits 26.2 miles.Scientists call this site Marathon Valley, because when therover reaches the area, it will have traveled the samedistance as the length of a marathon since its arrival onMars.Researchers believe that clay minerals exposed near Marathon Valley could hold clues to Mars ’s ancient environment1. Opportunity ’s continuing travels will also help researchers as they plan for an eventual human mission tothe Red Planet.41.Opportunity is a record breaking rover in the senseof_____.A. how long is has stayed in spaceB. how far it has traveledC. how much investment it has involvedD. how many facilities it has been equipped with42. What does John Callas say about Opportunity ’s long distance travel?A. It hasn’t met scientists’ expectation yetB .It hasn’t been appreciated appropriatelyC .It is secondary to what has been discoveredD .It is what scientists have been aiming at43.One of the objectives of sending Opportunityand Spirit is to_____.A. collect soil and send back to EarthB. develop multinational space explorationC. test how well solar-powered rovers work in outer spaceD. look for the possible presence of life44.Which of the following statements is trueof Opportunity?A. It will come back to earth soon.B. Another rover will be sent to replace it.C. It is travelling to XX(看不清，其余选项错误)D. It will work with other rovers exploring Mars45.暂缺第五局部：补全短文Explore JordanWadi Rum is the name given to a valley cut intothe sandstone and hard rock in southwest Jordan._______________46 The name Rum most likely comes from an Aramaic word meaning“high〞or“elevated〞, The area around Wadi Rum is now also one of Jordan’s most important tourist destinations, and attracts an increasing number offoreign tourists, particularly trekkers(越野者)，but also for camel safaris( 旅行 ) or simply day-trippers from Aqaba orPetra. In contrast, there are almost no local or Arabtourists through nearby disi attracts young people from Ammanat the weekends.Popular activities in the desert environment includecamping under the stars, riding Arab horses, and rock-climbing amongst the massive rock formations. Jebal Rum(Jebal means mountain) is 1,574 meters above sea level.___________47But Jordan is not simply a desert environment-----it also contains the area which is the lowest point to the face ofthe Earth----the incredible Dead Sea, popular with touristsfor swimming. _______48 Once the waters reach the Dead Sea they are landlocked and have nowhere to go, so they evaporate, leaving behind a dense, rich cocktail(混合的) of salts and minerals that supply industry, agriculture and medicine withsome of its finest products. Once again, tourists benefit andcan participate in water spa treatments and water therapies.The Dead Sea is located in the syro-African Rift, a4,000- mile fault line in the Earth’s crust. The lowest point of dry land on Earth is the shoreline of the Dead Sea at1,300 feet below sea level. Because the lake is at the lowestpoint, this means that water does not drain from it. ______49Figures for the Dead Sea ’s salinity( 盐度 ) today range from 25% to 35%.But the greatest tourist attraction is the incredible cityof Petra.______50 It is a vast unique city, carved intothe sheer rock face by the Nabataeans, an industrious Arab people who settled here more than 2,000 years ago, turningit into an important junction for the silk, spice and othertrade routes that linked China India and southern Arabia with Egypt, Syria, Greece and Rome. Today, visitors can marvel atthe architecture and explore life as it was thousands ofyears ago.A It is the largest wadi (riverbed) in Jordan.B It is the second highest peak in Jordan, risingdirectly above the Rum valley opposite Jebal Urn Ishrin.C This vast stretch of water receives a numberof incoming rivers, including the River Jordan.D The area has been used as a background setting ina number of films.E Every day seven million tons of water evaporate fromthe lake, but the minerals remain causing the salt content to increase.F It is without doubt Jordan’s most valuable treasure.第六局部：完形填空Rescue PlatformIn the aftermath of the terrorist attacks on the World Trade Center, security experts are trying to develop new ways ofrescuing people from burning skyscrapers.
