职称英语考试理工B阅读题2018职称英语考试理工B阅读精选题Desire to enhance the enthusiasm, perseverance rubdown alp.以下是店铺为大家搜索整理的2018职称英语考试理工B阅读精选题，希望能给大家带来帮助!Humans might be the most highly-evolved species on the planet, but most animals possess skills we can only dream of having. Imagine how much electricity we could save if we could see in the dark the way cats do. Imagine leaping from tree to tree like a monkey. Giraffes(长颈鹿), which are otherwise calm and good-natured, sleep only 4.6 hours a day.We realized a long, long time ago that nature provides the best blueprint(蓝图) for invention. We've borrowed canals from beavers(河狸) and reflectors from cat's eyes. Although the words "bionics" became popular only after the 1960s, history shows that nature has always provided ideas on solving everyday problems. Our archives(档案) don't go back to the time of Leonardo da Vinci and his bird-like flying machines, but we can take you to the late 19th century, where we applied those same principles for building our first practical airplanes.To prepare for their flight at Kitty Hawk, the Wright brothers studied the movements of pigeons to figure out how they stayed high up when they were heavier than air. Their success inspired scores of successors to improve on the airplane by studying various aspects of nature. One of Orville Wright's pupils caught and stuffed seagulls to examine their wingspan. Meanwhile, two French inventors examined spinning sycamore (梧桐) seeds in an effort to apply those same motions, reversed, to a helicopter.Some examples are more obvious than others. The outsideof the airplane designed by the Wright brothers looks like a minimalistic(简单抽象艺术) structure. On the other hand, Barney Connett's fish submarine(潜水艇) actually looks like a fish.Some bio-inspired concepts have yet to be invented. In the 1960s, the US Army commissioned several university professors to conduct research on the motor skills of animals in hope of applying those same abilities to tanks. Tanks that run like horses or jump like grasshoppers(蚂蚱)- sounds shocking, doesn't it? But imagine how life would change if we could achieve that.41. "Cats", "monkeys" and 'giraffes" mentioned in paragraph1 are examples to illustrateA. they are highly-evolved species as humans.B. animals have skills that humans do not possess.C. humans can learn animals' skills.D. they are skillful in different ways.42. Which of the following can be found in the archive gallery?A. First practical airplanes built in the late 19th century.B. History books.C. The Wright brothers' sculpture.D. Leonardo da Vinci's bird-like flying machines.43. What happened after the Wright brothers' success?A. People carried out a systematic study on pigeons.B. People could fly their airplane for fun.C. People kept their airplane at a French gallery.D. People studied more animals and plants to develop the airplane.44. Which of the following is true about the research carried out by the US Army?A. It has changed our life.B. It has cost a large sum of money.C. It has improved the abilities of tanks.D. It has not succeeded yet.45. What does the writer want to tell in the passage?A. Some animals possess unique skills.B. Many inventions get ideas from nature.C. People should protect nature.D. Bionics is far from perfect.参考答案：41. B42. A43.D44.C45.B。

职称英语考试真题理工类B级阅读理解（文字版）Can you hear This ?When something creates a sound wave in a room or an auditorium (礼堂)，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 .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 (弯曲的)reflecting surfaces create large reflections . Parallel (平行的)walls reflect sound back and forth, creating a rapid ,repetitive pulsing(有节奏的跳动)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 relectors 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 yo achieve a pleasing mixture of sound.1.This Passage is mainly aboutA sound waves and their acoustic effect .B the types of music orchestras playC walls of an auditoriumD the design of an auditorium2.Wagner operas and Mahler symphonies sound fuller in an auditorium with~ 2 / 3 ~A a short reverberation timeB a long reverberation timeC an intermediate reverberation timeD no reverberation time3.This passage suggests that a good auditorium shouldA achieve a pleasing mixture of soundB get rid of all reflectionsC not have absorbers.D have smooth surfacesrge pillars and corners mayA make sound rich and fullB be cures for sound problemsC be sources of sound problemsD function as well as clouds5.The word “acoustic “in the last paragraph has something to do withA performanceB MusicC soundD noiseSmart WindowWindows not only let light in to cut down an electricity use for lighting，but the light coming through the window also provides heat.However，windows are notsomething people typically associate with being a cutting edge1 technology.Researchers are now working on new technologies that enable a window to quickly change from clear to dark and anywhere in between with a flip of a switch2.“It took us a long time to figure out what a window really is,” says Claes Granqvist.He’s a professor of solid-state physics at Uppsala University in Sweden3.“It’s contact with the outside world.You have to have visual contact with the surrounding world to feel well.” So，windows and natural light are important for improving the way people feel when they’re stuck indoors.Yet，windows are the weak link in a building when it comes to energy and temperature control.In the winter，cold air leaks in.When it’s hot and sunny，sunlight streams in.All of this sunlight carries lots of heat and energy.And all of this extra heat forces people to turn ontheir air conditioners.Producing blasts of cold air，which can feel so refreshing，actually suck up enormous amounts of electricity in buildings around the world.Windows have been a major focus of energy research for a long time. Over the years，scientists have come up with a variety of strategies for coating，glazing，and layering windows to make them more energy efficient.Smart windows go a step further.They use chromogenic technologies which involve changes of color.Electrochromic windows use electricity to change color.For example，a sheet of glass coated with thin layers of chemical compound such as tungsten oxide works a bit like a battery.Tungsten oxide is clear when an electric charge is applied and dark when the charge is removed，that is，when the amount of voltage is decreased，the window darkens until it’s completely dark after all electricity is taken away.So applying a voltage determines whether the window looks clear or dark.One important feature that makes a smart window so smart is that it has a sort of “memory.” All it takes is a small jolt of voltage to turn the window from one state to the other.Then，it stays that way.Transitions take anywhere from 10 seconds to a few minutes，depending on the size of the window.The development of smart windows could mean that massive air conditioning systems may no longer need.“In the future,” Granqvist says,“our buildings may look different.”练习：1. Which of the following statements does not indicate the importance of windows as described in the first two paragraphs?A Windows can change from clear to dark to save energy.B Windows help to save energy by letting light in.C Windows help to save energy by providing heat.D Windows enable people to have contact with the outside world.2. When are windows the weak link in a building?A In the cold winter.B In the hot summer.C When air conditioners are turned on.D Both A and B.3. What are smart windows，according to Paragraph 4?A Windows that are coated.B Windows that are glazed.C Windows the color of which can be changed.D Windows that have many layers.4. To make electrochromic windows change color，what is applied to the windowglass?A Electricity.B Tungsten oxide.C A battery.D A voltage.5. What will he the benefit if the research on smart windows turns out to be successful，according to the last paragraph?A The buildings will look different.B Windows can be as large as you want.C We may not need air conditioners any more.D They are less expensive than traditional windows.词汇：flip n.比喻意为“最先进的，科技含量的”。

第一篇Its a Brand-new CenturyThe U. S. Treasury Department has redesigned the $100 bill, and has begun releasing the new currency recently. Treasury spent nearly 10 years on the redesign and has added a number of state of-the-art features: microprinting(微型印刷技术), color shifting ink, a polymer (聚合物) security thread. The most striking change, however, is the enlargement of Benjamin Franklins portrait: he now dominates the bill like a movie star in a newspaper advertisement.The money we carry around is so familiar that whenever a new bill or coin is introduced, it creates a ripple in our ordinary lives. But not much more than a ripple, and once few people use $100 bills regularly, most Americans greet the arrival of the new note with no stronger emotion than curiosity.Some foreigners, by contrast, have become clearly worried by the news of its arrival. Around the world, U. S. currency and the $100bill in particular is often treated as the ultimate repository(贮藏所)of value. The Federal Reserve estimates that two-thirds of all U. S. cash circulates outside the United States. In nations where inflation is high and where there are few credible bankinginstitutions from Latin America to Africa people save and conduct business in $100 bills. And with the U. S. issuing new $100bills,many abroad are worrying that the ones they already have are about to become worthless.The fear is most widespread in Russia. The Russian Central Bank estimates that somewhere between $15 billion and $20 billion of U. S. currency is in Russia,about 80% of it is the form of $100 bills. Everyone from small savers to businessmen and members of Mafia(黑手党)relies on hundreds, so the changes in the bill are causing high anxiety. Many Russians have already changed their meager(微不足道)supply of $100 bills into smaller U. S. notes. But over the next few years the Treasury plans to redesign every note except the $1bill.31 Which of the following statements is true concerning the releasing of the new $100 bill?A It has caused great disturbance among Americans.B Most Americans show a great interest in its new design.C All Americans feel only curious about it.D Most Americans exhibit no stronger emotion than curiosity.32 The fear of the new $100 bill is most widespread in those countries whereA the economic situation is unstable.B two-thirds of all U.S. cash circulator.C the old $100 bills will become more valuable.D there are too many old $100 bills circulating.33 Which of the following is true concerning U.S. currency in Russia?A The Russian Central Bank has $15 billion to $20 billion of U. S. currency.B 80 ~k of the $100 bills circulating outside the U. S. currency will be devalued.C There is a widespread fear in Russia that U. S. currency willbe devalued.D About 80 ok of U.S. currency in Russia is in the form of $100 bills.34 Why have many Russians changed their $100 bills into smaller notes?A The U. S. Treasure Department plans to redesign all notes except the $1 bill.B They are afraid that their $100 bills will lose their value.C Small savers, businessmen and members of the Mafia prefer smaller notes to $100 bills.D They have only a small supply of $100 bills.35 The redesign of the $100 bill has added all the following state-of-art features EXCEpTA the enlargement of Benjamin Frank portrait.B a polymer security thread.C the portrait of a famous movie star.D colour-shifting ink.第二篇&nb[1][2][3]下一页[1][2][3]下一页职称英语等级考试阅读理解模拟试题2sp; The Role of pressure Groups in BritainGeneral Elections in Britain are usually held only once everyfive years. Governments can seem to be remote from the people they represent. The process of protesting about government actions is very slow, even though everyone is permitted direct contact to their member of parliament. For all these reasons there is something of a vacuum between government and the governed, which pressure groups help to fill.。

第二篇Sports Star Yao MingIf YaoMing is not the biggest sports star in the world, he almost certainly thetallest. At 2.26m, he is the tallest player in the National BasketballAssociation (NBA) and holds the record as the most towering Olympian ever to competein the Game.But whatreally stands out about the giant center is his celebrity (名气). Few, if any, Chinese athletesare as well-known as Yao Ming around the world. People across the globe arefascinated with Yao, not only for his basketball prowess(接杰出的才能)but also for being a symbolof international commerce.When Yaojoined the Houston Rockets as the No. 1 pick in the 2002 NBA draft he was thefirst international player ever to be selected first. His assets on the courtare clear enough 一no NBA playerof his size has ever possessed his mobility, so he is a handful (难对付的人）for opponents on either end ofthe court. But what makes Yao invaluable to the Rockets organization is hisrole as a global citizen and as a bridge to millions of potential basketballfans in China.When itwas announced in February that Yao would miss the rest of the NBA season andpossibly the Olympics with a stress fracture (骨折）in his left foot, a collective shudder spread across China. Afterconsiderable debate and discussion, Yao opted to get his foot surgicallytreated in an operation that placed several tiny screws across the bone, tooffer his overburdened foot more support. The surgery was asuccess, and thoughthe estimated four-month recovery period will leave him little time to preparewith Team China. Yao has vowed to be ready for the Beijing Olympics.Yaowrapped up a 10-day trip to China, where he underwent a series of traditionalChinese medicine (TCM) treatments, hoping to accelerate his recovery process.Western experts are generally skeptical of TCM’s benefits, although newresearch from the University of Rochester suggests that a certain compoundderived from shellfish may indeed stimulate bone repair.“Thereis no reason to dismiss TCM, “ Yao told a press conference in Beijing. “It’sbeen used in our country for thousands of years. I don’t think that it’s shorton science.”36. Theword“towering”in Paragraph 1 meansA. large.B. fat.C. tall.D. great.答案：C37. Opponentsfind it very difficult to control Yao Ming because of hisA. mobility.B. assault.C. defense.D. celebrity.答案：A38. YaoMing had to undergo a series of TCM treatments becauseA. hisright foot had been hurting.B. he wanted to make a more rapid recovery.C. thesurgical operation had been a failure.D. hecouldn’t afford all the medical expenses.答案：B39. Whichstatement about Yao Ming is NOT true?A. He missed the Athens Olympics.B. Heis an NBA player.C. Hefractured his left foot.D. Heis an international figure.答案：A40. Ingeneral, the Western experts’ attitude towards TCM isA. indifferent.B. positive.C. negative.D. doubtful.答案：D。

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.
