职称英语考试理工类(B级)试题及题解5第二篇Credit Card Only Works When Spoken toA credit card that will not work unless it hears its owner’s voice could become an important weapon in the fight against fraud(欺骗)．The card requires users to give a spoken password that it recognizes using a built-in V oice-recognition chip．The idea is to prevent thieves using a stolen card or fraudsters using someone else’s credit card details to buy goods online．A model built by engineers at Beepcard in Santa Monica，California，represents the first attempt to pack a microphone。

a loudspeaker，a battery and a voice·recognition chip into a standard．sized credit card．They are not quite there yet：the card is the length and width of an ordinary credit card，but it is still about three times as thick．The company now plans to make it thinner．The voice card is based on an earlier Beepcard technology designed to prevent fraud in online transactions This earlier card has no microphone，but has a built·in loudspeaker that it uses to“squawk”(发出叫声)a voice ID signal via a computer’s microphone to an online server．By verifying(证实)that the signal matches the card details，the server can establish that the user is not simply keying in a credit card number but actually has the card to hand．The ID code changes each time the card is used in a pre—ordered sequence that only the server knows．This prevents fraudsters recording the beeps，noting the card details and then playing back the audible ID when they key in the details later But this earlier technology cannot prevent fraudulent use of stolen cards The new one can The newvoice card also identifies itself by its ID squawk．but it will not do this until it has verified the legitimate(合法的)user’s spoken password Thieves will be unable to use the card because even if they knew the password they would have to be able to copy the owner’s voice with a high degree of accuracyThe challenge for Beepcard has been to develop voice-recognition and audio circuitry that Can be powered by a mini battery embedded(嵌入的)in a credit card．To maximize battery life，the electronics are only switched on when the card is being used．Pressing a button on the card’s surface prompts it to utter “Say your password ”in female voice If the voice—recognition software proves that the password is authentic(真实的)，it sends its ID squawk which the server then identifies．allowing the transaction to proceed36 The voice credit card is an important invention becauseA it can be made cost-effectively．B it can leave voice messages，C it makes online shopping easyD it makes fraud difficult．37 What is the problem which the model card?A It is too large．B It is toot hickC It can’t be used in online transactionsD It doesn’t have a loudspeaker．38 Which of the following statements about the earlier card is true?A Its owner can change the ID code freelyB Its user does not need to key in the ID number．C It can record its user’s spoken password．D It still can be used by someone else after being stolen．39 What is the advantage of the new voice card?A It recognizes only its owner’s spoken password．B It doesn’t need to work with an online serverC It requires less ID information．D It has a playback function40 What can we learn from the last paragraph about the voice card?A Only female voice passwords could be recognized．B Further improvement should be made to extend battery lifeC There is no limit to its application．D Female customers like to use it。

02年职称英语考试理工类(B级)试题及答案6第三篇Black HoiesWhat is a black hole?Well，it’s difficult to answer this question，since the terms we normally use to describe a scientific phenomenon are inadequate here．Astronomers and scientists think that a black hole is a region of space(not a thing)into which matter has fallen and from which nothing can escape-not even light．So we can’t see a black hole．A black hole exerts(施加)a strong gravitational(重力的)pull and yet it has no matter．It is only space-or so we think. How can this happen?The theory is that some stars explode when their density increases to a particular point；they”collapse”and sometimes a supernova(超新星)occurs．The collapse of a star may produce a“White Dwarf (白矮星)”of a”neutron star”一a star whose matter is so dense that lt continually shrinks by the force of its own gravity．But if the star is very large this process of shrinking may be so intense that a black hole results．Imagine the earth reduced to the size of a marble，but still having the same mass and a stronger gravitational pull，and you have some idea of the force of a black hole．Any matter near the black hole is sucked in．It is impossible to say what happens inside a black hole．Our space and time laws don’t seem to apply to objects in the area of a black hole.Einstein’s relativity theory is the only one that can explain such phenomena．Einstein claimed that matterand energy are interchangeable．so that there is no”absolute”time and space. There are no constants at all, and measurements of time and space depend on the position of the observer-they are relative．Einstein’s theory provided a basis for the idea of blackholes before astronomers started to find some evidence for their existence．It is only recently that astronomers have begunspecific research into black holes．The most convincing evidence of black holes comes from research into binary(由两部分组成的) star systems．In some binary star systems，astronomers have shown that there is aninvisible companion star,a”partner”to the one which we can see in the sky．There is one star,called by its catalogue number HDE 226868．which must have a partner．This partner star,it seems．has a mass ten or twenty times greater than the sun-yet we can’t see it．Matter from HDE 226868 is being dragged towards this companion star．Could this invisible star,which exerts such a great force，be a black hole?Astronomers have evidence of a few other stars too，which might have black holes as companions．4l Which of the following does NOT fit the definition of the black hole?A The black hole is a region of space．B The black hole sucks in any object that passes by it．C The black hole is visible through an infrared telescope．D The black hole has no matter．42 Why does the author p ut”neutron star”in quotation marks?A It is a special term of astronomy．B It is an inventedterm．C He is quoting an authority．D He is using the term ironically．43 What leads to the formation of a black hole?A The structure of a star．B A collision between two stars．C The attraction of two large stars．D The shrinking of a large star by its own gravitational force.44 According to Einstein’s theory,objects in the area of a black holeA are gathered in its center．B strike against one another frequently．C do not have absolute space．D are relatively brighter．45 We learn from this passage thatA the sun is the heaviest star in the universe．B a star in the sky might have an invisible partner．C two black holes are dragged towards each other．D the mass of a star is equal to that of its companion.。

第一篇Smart WindowsWindows not only let light in to cut downon electricity use for lighting, but thelight coming through the window also provides heat. However, windows are notsomething people typically associate with an advanced technology. Reseachersare now working on new technologies that enable a window to quickly change fromclear to dark and anything in between easily.“It took us a long time to figure out whata window really is,”says Claes Granqvist. He’s a professor of solid-statephysics at Uppsala University in Sweden. “It contact with the outside world.You have to have visual contact with the surrounding world to feel well.” So,windows and n atural light are important for improving the way people feel whenthey’re stuck indoorsYet. windows are the weak link in abuilding when it comes to energy and temperature control. In winter cold airleaks in. When it’s hot and sunny, sunlight streams in. All of this sunlightcarries lots of heat and energy. And all of this extra heat forces people toturn on their conditioners. Producing blasts of cold air, which can feel so refreshing(使人清新的)，actually sucks up enormous amountsof electricity in buildings around the world.Windows have been a major focus of energyresearch for a long time. Over the years, scientists have come up with a varietyof strategies for coating, glazing (用玻覆盖)，and layeringwindows to make them more energy efficient. Smart windows go a step further.They use chromogenic (发色的）technologies which involve changes of color.Electrochromic (电致色的）windows use electricity tochange color. For example, a sheet of glass coated with thin layers of chemicalcompound such as tungsten oxide (氧化钨)works a bit like a batter. Tungsten oxides is clear when anelectric charge is applied and dark when the charge is removed, that is, whenthe amount of voltage(电压)is decreased, the window darkens until it’s completely dark afterall electricity is taken away. So applying a voltage determines whether thewindow looks clear or dark.One important feature that makes a smartwindow so smart is that it has a sort of“memory”. All it takes is a small changeof voltage to turn the window from one state to the other. Then, it stays thatway. Transits take anywhere from in10 seconds to a few minutes, depending onthe size of the window. The development of smart windows could mean thatmassive air conditioning systems may no longer be needed. “In thefuture,”Granqvist says, “our buildings may look different.”31. Which of the following of values ofwindows is NOT mentioned?A. Theylet light in to brighten the house.B. Theylet light in to heat the house.C. Theylet us have visual contact with the surrounding world.D. They let us think about the outside world.答案：D32. The expression “when it comes to “ inParagraph 3 is used toA. signalthe arrival of a guest.B. indicatethe recovery of consciousness.C. show our understanding of something.D. introduce a new aspect of a topic.答案：D33. According to Paragraph 4, smart windowsare the windows thatA. are coated.B. are glazed.C. have several layers.D.can change color.答案：D34.

It draws on date that came from NASA’s top planet-hunting telescope.A mechanical failure recently put that Kepler space telescope out of service. Kepler had played a big role in creating a census of planets orbiting some 170,000 stars. Its data 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 star’s habitable zone. That’s where the surface temperature would allow any water to exist as a liquid.The new estimate of how many planets might fit these conditions comes from studying more than 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 to the Sun as Venus and running to as far away as Mars. Neither planet is Earthlike (although either might have been in the distant past). Using tighter limits, the researchers estimate that between 4 and 8 out of every 100Sunlike stars could host an Earth-sized world. These are ones that would take 200 to 400days to complete a yearly orbit.mean,however, that the Milky Way could host more than a billion Earth-sized planets with a change for life.16.

Earth is warming. Sea levels are rising. There ‘s more carbon in the air, and Arctic ice is melting faster than at any time in recorded history. Scientists who study the environment to better gauge (评估) .Earth’s future climate now argue that these changes may not reverse for a very long time .2 . People burn fossil fuels like coal and oil for energy. That burning releases carbon dioxide, a colorless gas . In the air , this gas traps heat at Earth’s surface . And the more carbon dioxide released , the more the planet warms . If current consumption of fossil fuels doesn’t slow ,the long-term climate impacts could last thousands of years-and be more severe than scientists had been expecting. Climatologist Richard Zeebe of the University of Hawaii at Manoa offers this conclusion in a new paper.3. Most climate-change studies look at what’s going to happen in the next century or so .During that time, changes in the planet’s environment could nudge(推动) global warming even higher. For example: Snow and ice reflect sunlight back into space. But as these melt,sunlight can now reach-- and warm –the exposed ground . This extra heat raises the air temperature even more, causing even more snow to melt. This type of rapid exaggeration of impacts is called a ‘fast feedback’.4. Zeebe says it’s important to look at fast feedbacks. However, he adds, they’re limited.From a climate change perspective, ‘This century is the most important time for the next few generations’, he told Science News “But the world is notfast feedback events unfold over decades or centuries, slow feedbacks can take thousands of years. Melting of continental ice sheets and the migration of plant life --- as they relocate to more comfortable areas --- are two examples of slow feedbacks.5. Zeebe gathered information from previously published studies investigating how such processes played out over thousands of years during past dramatic changes in climate. Then he came up with a forecast for the future that accounts for both slow and fast feedback processes. Climate forecasts that use only fast feedbacks predict a 4.5 degree Celsius (8.1 degree Fahrenheit) change by the year 3000. But slow feedbacks added another 1.5 ℃--for a 6 total increase, Zeebe reports. He also found that slow feedback events will cause global warming to persist for thousands of years after people run out of fossil fuels to burn.23. Paragraph 2 ________ 答案：B24.

职称英语考试理工类(B级)真题及答案4第二篇Where Have All the Bees Gone?Scientists who study insects have a real mystery on their hands.All across the country, honeybees are leaving their hives(蜂巢)and never returning.Researchers call this phenomenon colony-collapse(群体瘫痪)disorder.It is reposed that 25 to 40 percent of the honeybees in the US have vanished from their hives since last fall.So far, no one can explain why.Colony collapse is a serious concern because bees play an important role in the production of about one—third of the foods we eat.As they feed，honeybees spread pollen (花粉)from flower to flower.Without this process，a plant can’t produce seeds or fruits.Now，a group of scientists and beekeepers have teamed up to try to figure out what’S causing the alarming collapse of SO many colonies.They hope to find out what’S contributing to the decline and to prevent bee disappearance in the future.It could be that disease is causing the disappearance of the bees.To explore that possibility, Jay Evans，a researcher at the United States Department of Agriculture (SDA)Bee Research Laboratory, examines bees taken from colonies that are collapsing.“We know what a healthy bee should Look Like on the inside.and we can look for physical signs of disease.”he says.And b ees from collapsing colonies don’t look very healthy.“Their stomachs are worn pared to the stomachs of healthy bees，”‘Evans says.It may be that a parasite(寄生虫)making the bees’digestive organs. Their immune(免疫的)systems may not be working as they should.Moreover，they have high levels of bacteria inside their bodies.Another cause of colony—collapse disorder may be certain chemicals that farmersapply to kill unwanted insects on crops，says Jerry Hayes，chief bee inspector for the Florida Department of Agriculture.Some studies，he says，suggest that a certain type of insecticide(杀虫剂)affects the honeybee’S newels system and memory.“It seems like honeybees are going out and getting confused about where to go and what to do”he says.1f it turns out that a disease is contributing to colony collapse，bees’genes could explain why some colonies have collapsed and others have not.In any group of bees there are many different kinds of genes.The more different genes a group has，the higher the group’S genetic diversity.So far scientists haven’t determined the role of genetic diversity in colony collapse，but it’s a promising theory，says Evans.36. What is the mystery that researchers find hard to explain?A. Honeybees are flying all across the country.B. Half of the honeybees in the US have died.C.

职称英语考试理工类〔B 级〕试题及答案5第二篇Hurricane〔飓风〕KatrinaA hurricane is a fiercely powerful,rotating〔旋转的〕form of tropical storm that can be 124 to 1,240 miles in diameter.The term hurricane is derived from Hurican,the name of a native American storm god.Hurricanes are typical of a calm central region of low pressure between 12 to 60 miles in diameter,known as the eye.They occur in tropical regions.Over its lifetime,one of these can release as much energy as 10,000 nuclear bombs.The seed for hurricane formation is a cluster〔聚集〕of thunderstoms over warm tropical waters.Hurricanes can only form and be fed when the sea-surface temperature exceeds 27 C and the surrounding atmosphere is calm.These requirements are met between June and November in the northern part of the world.Under these conditions,large quantities of water evaporate〔蒸发〕and condense 〔冷凝〕in to clouds and rain-releas ing heat in the process .It is this heat energy,comb ined with the rotation of the Earth,that drives a hurricane.When the warm column of air from the sea surface first begins to rise,it causes an area of low pressure.This in turn creates wind as air is drawn into the area.This spinning wind drags up more moist air from the sea surface in a process that strengthens the storm.Cold air falls back to the ocean surface through the eye and on the outside of the storm.Initially,when wind speeds reach 23 miles per hour,these mild,wet and grey weather systems are known as depressions,or low air pressure.Hurricane Katrina formed in this way over the south-eastern Bahamas on 23 August 2005.Katrina has had a devastatingimpact on the Gulf Coast of the US,leaving a disaster zone of 90,000 square miles in its wake〔尾迹〕-almost the size of the UK.Thousa nds have bee n killed or injured and more than half a million people have become homeless in a humanitarian〔人道主义的〕crisis of a scale not seen in the US since the Great Depression.The cost of the damage may top $100 billion.36. The eye of a hurricane refers to itsA. lower part.B. rotating part.C. calm central part.D. most violent part.37. Which of the following is NOT a “ requirement 〞thfoer formation of a hurricane?A. Calm surrounding atmosphere.B. High air pressure.C. Warm sea-surface temperature.D. A group of thunderstorms over warm tropical waters.38. When the warm air from the sea surface begins to rise,itA. creates an area of low pressure.B. supplies cold air to the eye of a hurricane.C. increases the sea-surface temperature.D. strengthens the rotation of the earth.39. The word “impact 〞〔paragragh 5〕could be best replaced byA. “ function 〞.B. “ pressure 〞.C. “ disaster 〞.D. “ effect40. Which of the following is NOT true of Hurricane Katrina according to the last paragraph?A.The area affected is almost as big as the UK.B. It has left a disaster zone of 90,000 square miles.C. Over half a million people have been forced to leave their homes.D. This crisis is more serious than that of the Great Depression。
