Eta Carinae
As possibly the galaxy’s (银河) most massive star, Eta Carinae is now engaging in some very unusual behaviour. Australian astronomers, being in the Southern Hemisphere (半球), are able to observe it clearly.
In the 19th century, Eta Carinae was for a time the third brightest star in the sky. It has now become less bright so that binoculars (双筒望远镜)are ne eded to see it. “It seems to be brightening and becoming less bright over a period of many years”, said Dr Bob Duncan from the Australia Telescope National Facility.
While it is not unusual for stars to vary in brightness, the period is usually much s horter. “Since 1992 it has become four times brighter, and then last year it began to drop dramatically,” he said.
The problem in observing Eta Carinae is that it has been surrounded by a cloud of gas and dust, making it hard to see the star directly. However, radio waves and infrared light (红外线)can pass through this cloud, so telescopes that receive these wavelengths can observe what is occurring.
Eta Carinae is of particular interest to astronomers because it seems to be in its death throes（剧痛）. Being so large it will end up as a supernova (超新星). There has not been a supernova in our galaxy since the invention of the telescope. While a 1987 explosion in a nearby galaxy gave astronomers plenty of valuable data, they are
hungry for an even closer look.
Eta Carinae has other unique features, and is the only star known to produce an ultraviolet(紫外线)laser that is brighter than that produced by the Sun. Lasers have been observed in other frequencies from a few stars.
31. Eta Carinae is now engaging in
A. some very common behaviour
B. some very dull behaviour
C. some very frightening behaviour.
D. some very strange behaviour
32. The word “period” in Paragraph 3 means the length of time
A. over which star vary in brightness
B. for which Eta carinae’s brightening lasts.
C. Eta carinae takes to become a supernova.
D. it takes the laser from Eta carinae to travel to the earth.
33. Eta Carinae is hard to observe because
A. it is too far away.
B. there is too much dust and gas around it.
C. the binoculars are not powerful enough.
D. it does not send out infrared light.
34. Astronomers are particularly interested in Eta Carinae because
A. it is in its final stage.
B. it is a supernova.
C. it exploded in 1987.
D. it is brighter than the sun.
35. Which of the following statements about Eta Carinae is NOT true?
A. It will end up as a supernova.
B. It can be seen only through binoculars.
C. It is the only star that sends out an ultraviolet laser.
D. Its ultraviolet laser is brighter than that of the Sun.。

Residents now wonder when the next"big one"willstrike.It's bound to happen someday.At least seven active fault（断层）lines run through the SanFrancisco area.Faults are places where pieces of earth's crust（地壳）slide past each other.Whenthese pieces slip，the ground shakes.To prepare for that 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 at about 2.7 kilometersper second.During bigger quakes，however，ruptures can happen at rates faster than 3.5 kilometersper second.At such high speeds，massive amounts of pressure build up，generating underground waves that can cause more damage than the quake itself.Luckyfor San Fancisco，these pressure pulses（脉冲）traveled alway from the city duffng the 1906 event.As bad as the damage was，it could have been farWorse.Looking ahead，scientists are trying to predict when the next major quake will occur.Records show that earthquakes were common before 1906 event. Since then，the area has been relatively quiet.Pattems in the data，however，suggest that the probability of a major earthquake 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 qmet for a while.Accoeding to the new research，however，it's not a matter of whether the big one will hit. It's just a matter of when.16.

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 themoney 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.16.

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。

第一篇Pushbike DangerLow speed bicycle crashes can badly injure——or even kill——children if they fall onto the ends of the handlebars(车把)．So a team of engineers is redesigning it to make it saferKristy Arbogast，a bioengineer at the Children’s Hospital of Philadelphia in Pennsylvania，began the project with her colleagues．The cases they reviewed about serious abdominal(腹部的)injuries in children in the past 30 years showed that more than a third were caused by bicycle accidents．”The task was to identify how the injuries occurred and come up with seine countermeasures，”she saysBy interviewing the children and their parents，Arbogast and her team were able to reconstruct many of the accidents and identified a common cause for serious injuries They discovered that most cases occur when children hit an obstacle at slow speed，causing them to topple (摇摆)over．To maintain their balance the children turn the handlebars through 90degrees—but their momentum(冲力)forces them into the end of the handlebars．The bike then falls over and the other end of the handlebars hits the ground，pushing it in to their abdomen(腹部)．The solution the group came up with is a handgrip (握柄)fitted with a spring and damping(减速)system. The spring absorbs up to 50 per cent of the forces transmitted(传递)through the handlebars in all impact．The group hopes tocommercialize the device，which should add only a few dollars to t}le cost of a bike．“But our task has been one of education because up until now．bicycle manufacturers were unaware of the problem，”says Arbogast．31 The engineers are trying to improve the handlebars becauseA they are not beautifulB they may kill childrenC they are likely to crash．D they affect the speed of the bike32 How many abdominal injuries in children were caused by bicycle accidents?A Thirty．B Ninety．C 50 percent．D More than a third.33 The world “countermeasures” in paragraph 2 meansA “problems”B “approaches”C “solutions”．D “actions”34 Paragraph 3 mainly discussesA why the children and their parents were interviewedB how serious abdominal injuries occur.C when the children turn the handlebarsD what stops bicycle accidents35 The advantage of the new handgrip is thatA it can be made cheaply.B it reduces the impact in bicycle accidents．C it helps to slow down the speed of the bicycle．D it sells well at bicycle shops．。

Its date have been helping astronomers predict how common planets are in our galaxy.The telescope focused on hunting planets that might have conditions similar to those on Earth.The authors of a study published in The Proceedings of the National Academy of Sciences conclude that between 14 and 30 out of every 100 stars with a mass and temperature similar to the Sun may host a planet that could support life as we know it.Such a planet would have a diameter at least as large as Earth’s but no more than twice that big.The planet also would have to orbit in a stor’s habitable zone. That’s where the surface temperature would allow any water to exist as liquid.The new estimate of how many plantes might fit these conditions comes from studying more that 42,000 stars and identifying suitable worlds orbiting them.The scientists used those numbers to extrapolate(推算) to the rest of the stars that the telescope could not see.The estimate is rough，the authors admit. If applied to the solar system，it would define as habitable a zone starting as close ot the Sun as Venus and running to as far away as Mars. Neither planet is Earthlike(although either might have been in the distant pase). Using tighter limits the researchers estimate the between 4 and 8 out of every 100 sunlike stars could host an Earth-sized world.These are ones that would take 200 to 400 days to complete a yearly orbit.Four out of every 100 sunlike stars doesn’t sound like a big number. It would mean however that the Milky Way could host more than a billion Earth-sized planets with a chance for life.16.

Anyone hoping to pedal to work there has to contend with steep streets like Canton Avenue，which famously climabs ata nearly 40-degree angle.As a result，some residents avoid biking altogether.2 But University of Pittsburgh graduate Micah Toll，23，and a few friends recently launched an invention that they hope will increase the city’s pedal pow er. An electric bike called to Pulse PEVO. A super-strong battery powers the bicycle. Able to hit nearly 20 miles per hours without pedaling，it zips battery powers the bicycle. Able to hit nearly 20 miles per hour without pedating ，it zips up the city’s mo st daunting(令人却步的)hills.Toll hopes it will persuade people in Pittsburgh and elsewhere to get out of their cars and onto bikes.3 If it sounds like Toll has a knack(窍门) for fixing problems，that’s because he does. In high school，he designed a new type of construction beam. It weights no more than a feather pillow but can be used to build sturdy(坚固的)homes for refugees fleeing war or natural disaster.For his work，Toll was invited to attend the Inter International Science and Engineering Fair(Isef)—twice，in 2006 and 2007. Theannual competition for young researchers is program of Society for Science linguistic, mathematical, spatial, musical, Interpersonal, intrapersonal, body-kinesthetic(身体动觉的),and naturalistic .31. What is the main idea of this passage?A. How to understand intelligence.B. The importance of intelligence.C. The development of intelligence tests.D. How to become intelligent.32. Which of the following statements is true concerning general intelligence?A. Most intelligent people do well on some intelligence tests.B. People doing well on one type of intelligence test do well on other tests.C. Intelligent people do not do well on group tests.D. Intelligent people do better on written tests than on oral tests.33. Gardner believes that ________.A. children have different intelligences.B. all children are alike.C. children should take one intelligence test.D. there is no general intelligence.34. According to Gardner, schools should ________.A. test students’IQs.B. train students who do poorly on tests.C. focus on finding the most intelligent students.D. promote development of all intelligences.35. Gardner thinks that his theory has a ________ .A. musical foundation.B. biological foundation.C. intrapersonal foundation.D. linguistic foundation.答案：ABADBMusic is one of the most beautiful forms of artistic expression是ever invented. In movies and plays，music has an added function：it not only moves people but also can shock people.Our eardrums can withstand sound within 20 to 80 decibels(分贝).Once sound exceeds this limit，even beautiful music will become ear-splitting noise and harm health.A strong blast(响声) of high sound can twist and break a solid iron sheet.High sound of 150 decibels can kill a healthy rat.In movies，sometimes the hero can produce a sound that ordinary people can’t hear and only those who have the same ability can feel.In nature，there is actually sound that is beyond our hearing. In physics，the sound that exceeds 20000Hz is called ultrasonic(超音波的).Dolphins，whales and bats can make such high-frequency sound.It does no harm to health.Sound less than 20Hz is called infrasonic(次声)waves. When we move，the air will vibrate. The vibration of air can produce infrasonic wave.As the frequency of infrasonic waves is close to that of people’s internal organs，infrasonic wave may cause resonance(共振) in human bodies. As a result，people’s vision may weaken and internal organs may rupture(断裂). However，whether an infrasonic wave can be used as a weapon depends on its intensity. If its intensity is very low，it won’t damage internal organs or a person’s health. If the intensity of inf让sonic wave exceeds 160decibels，it is extremely harmful. When wind blows at a force of 3 or 4 over the sea，it will produce infrasonic waves of several decibels. Only typhoons can produce infrasonic waves of over 100 decibels. At present，scientists can only produce infrasonic weapons in the lab with the help of advanced scientific tools and powerful electric power.36 What could be the best title of the passage?A The power of musicB The harms of noisesC The magic of soundD The discovery of infrasonic waves37 What does the author say about music?A It may be harmful to people’s halthB It always cheers people upC It is very often difficult to understandD It sounds better when it is lound enough38 It is true that the soundA of nature is the most beautifulB over 80 decibels is harmful to peopleC of high intensity benefits animalsD in movies is pleasing to the ear39 An ultrasonic soundA is very loudB does harm to people’s healthC cannot be heard by peopleD is produced by the hero in movies40 It can be found from the last paragraph that infrasonic wavesA are harmless to people’s healthB exist in people’s internal organsC can be used as deadly weaponsD can improve eyesight答案：CABCCCompact DisksIf someone says to you your music CDs don’t really hold any music on them, and they only have numbers recorded on them, you may not believe it. In fact, he is right in that sound is actually recorded onto the CDs as special numbers — a digital code.1 The code is pressed onto the CD as bumps on a long spiral track almost five kilometers long. These bumps are an average of 0.5 microns wide.A small laser beam shines onto the bumps as the CD turns. The light is reflected back to a receiver that records how the laser light bounces back. This lets the CD player2 turn the reflected light back into the original code. This means you can hear the original code as music.Digital codes are used with many technologies. E-mail needs these kinds of code numbers. Space probes communicate with their ground station on earth using digital codes. Bar codes are read as digital codes in computer systems. Digital communications with cell phones need digital codes. Weather radios also tune into specific signals using these codes.There are many types of compact disks. One format is called CD-RWs. They can be recorded on and re-recorded on(rewritten on)as you would do with a floppy disk3.Another format is the CD-ROM. The technology for recording on these disks is different from other CDs. These CDs have a dye layer that the CD writer can darken or leave clear. The clear and dark spots are the digital code. CD-ROM stands for Compact Disc —Read Only Memory4. This disk is like a “super” floppy disk that can hold lots of information. One CD-ROM can hold the same amount of data as 500 floppy disks. Information is permanently recorded onto it. Computer games and other programs are considered to be CD-ROMs.CDs were first sold to the public in 1982These CDs still play well and sound fine. Current CDs are expected to last between 70 to 200 years. Of course, you can make sure your CDs last a long time by taking care of them.Science keeps on developing. It may not be many more years before a completely new technology is invented5 and introduced to the public for music recording. In the meantime, there is no doubt you will continue to enjoy listening to your favorite music on CDs6 and playing your favorite computer games on CD-ROMs.41 Music is recorded onto CDs asA laser beamsB digital codesC musical notesD special sounds42 E-mail is mentioned in the third paragraph to showA the variety of digital communicationsB the development of new technologiesC the usefulness of digital codesD the relationship between communication and technology43 One of the differences between CD-RWs and CD-ROMs isA CD-ROMs can be used for longer timeB CD-ROMs cannot be rewritten onC CD-RWs hold more informationD CD-RWs are merely used for music recording44 CDs can last a long time ifA they are seldom usedB they play well and sound fineC their users take good care of themD they are developed with new technology45 It can be inferred from the passage thatA CD-ROMs are more expensive than other CDsB new technology for music recording is being developedC the author likes listening to musicD flppy disks are no longer in use答案：BCBCC第5部分，补全短文Do You Have a Sense of Humor?Humor and laughter are good for us. There is increasing evidence that they can heal us physically，mentally，emotionally，and spiritually. In fact，every system of the body responds to laughter in some positive，healing way. So how can we get more laughter into our lives?(46)Psychologist and author，Steve Wlison，has some answers.Many peoplebelieve that we are born with a sense of humor.They think，“either you’ve got it，or you don’t”Dr.Wilson points out that this false.(47)The parts of brain and central nervous system that control laughing and smiling are mature at birth(48)(After all ，when a baby laughs，we don’t rush over and say，“That kid has a great sense of humor!”)A sense of humor is something that you can deve lop over a lifetime.Sometimes people think that they don’t have a good sense of humor because they are not good joke tellers.Dr.Wilson reminds us that telling jokes is only one of many ways to express humor.(49)Then we will make others laugh，too.A person who has a true sense of humor is willing and able to see the funny side of everyday life.One of the best definition of a sense of humor is“the ability to see the nonserious element in a situation.”Consider this sign from a sore window.“Any faulty merchandise will be cheerfully replanced with merchandise of equal quality.”The store manager probably placed the sign in the window to impress customers with the store’s excellent service.(50)As Dr.Wilson says，“a good sense of humor means that you don’t h ave to be funny;you just have to see what’s funny.”A He advises us to lose our inhibitions(抑制)and try to laugh at ourselves.B Is it possible to develop a sense of humor?C However，that does not mean that infants have a sense of humor.D What is true，however，it that we are born with the capacity to laugh and smileE Everyone experiences this emotionF He had a serious purpose，but if you have a sense of humor，you will probably find the sign funny!答案：BDCAF第6部分：完形填空(第51~65题，每题1分，共15分)Citizen ScientistsUnderstanding how nature responds to climate change will require monitoring key life cycle1 events —flowering, the appearance of leaves, the first frog calls of the spring —all around the world. But ecologists can’t be everywhere so they’re turning to non-scientists, sometimes called citizen scientists, for help.Climate scientists are not present everywhere. Because there are so many places in the world and not enough scientists to observe all of them, they’re askin g for your help in observing signs of climate change across the world. The citizen scientist movement encourages ordinary people to observe a very specific research interest — birds, trees, flowers budding, etc. — and send their observations to a giant database to be observed by professional scientists. This helps a small number of scientists track a large amount of data that they would never be able to gather on their own. Much like citizen journalists helping large publications cover a hyper-local beat2, citizen scientists are ready for the conditions where they live. All that’s needed to become one。

职称英语考试理工类(C级)试题6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 closing in.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 picks up signals from navigation satellites such as the NA VSTAR 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 mixingof 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 computer could 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 NA VSTAR 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-car computerA 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 road construction,weather conditions,and traffic jams.D Showing the car’s position at all times and displaying it on the map.。
