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.

2019年职称英语考试：理工类B级阅读题(4)第二篇 Mind-reading MachineA team of researchers in California has developed a way to predict what kinds of objects people are looking at by scanning what‘s happening in their brains.When you look at something， your eyes send a signal about that object to your brain. Different regions of the brain process the information your eyes send. Cells in your brain called neurons are responsible for this processing.The fMRI (functional Magnetic Resonance Imaging) brain scans could generally match electrical activity in the brain to the basic shape of a picture that someone was looking at.Like cells anywhere else in your body， active neurons use oxygen. Blood brings oxygen to the neurons， and the more active a neuron is， the more oxygen it will consume. The more active a region of the brain， the more active its neurons， and in turn， the more blood will travel to that region. And by using fMRI， scientists can visualize which parts of the brain receive more oxygen-rich blood——and therefore， which parts are working to process information.An fMRI machine is a device that scans the brain and measures changes in blood flow to the brain. The technology shows researchers how brain activity changes when a person thinks， looks at something， or carries out an activity like speaking or reading. By highlighting the areas of the brain at work when a person looks at different images， fMRI mayhelp scientists determine specific patterns of brain activity associated with different kinds of images.The California researchers tested brain activity by having two volunteers view hundreds of pictures of everyday objects， like people， animals， and fruits. The scientists used an fMRI machine to record the volunteer‘s brainactivity with each photograph they looked at. Different objects caused different regions of the volunteers’ brains to light up on the scan， indicating activity. The scientists used this information to build a model to predict how the brain might respond to any image the eyes see.In a second test， the scientists asked the volunteers to look at 120 new pictures. Like before， their brains were scanned every time they looked at a new image. This time，the scientists used their model to match the fMRI scans to the image. For example， if a scan in the second test showed the same pattern of brain activity that was strongly related to pictures of apples in the first test， their model would have predicted the volunteers were looking at apples.36 What is responsible for processing the information sent by your eyes?A A small region of the brain.B The central part of the brain.C Neurons in the brain.D Oxygen-rich blood.。

It may seem like an ordinary end to a humble life ， but there was something quite exceptional about this woman . 1 In the summer of 1995 ， McCartygave $ 150，000， most of the money she had saved throughout herlife ， to the University of Southern Mississippi in her hometown . The money was to help other African Americans through university .She had started her savings habit as a young child when she would return from school to clean and iron for money which she would then save . She led a simple ， frugal existence ， never spending on anything but her most basic needs . 2 Her bank also advised her on investing her hard - earned savings . When she retired ， she decided that she wanted to use the money to give children of limitedMeans the opportunity to go to university . 3 She had wanted to become a nurse ，but had to leave school to look after ill relatives and work . When asked why she had given her life savings away ， she replied ， Im giving it away so that children wont have to work so hard ， like Idid . After news of her donation hit the media ， over 600 donations were made to the scholarship fund . One was given by media executive ，Ted Turner ， who reputedly gave a billion dollars . She didnt want any fuss made over her gift ， but the news got out and she wasinvited all over the United States to talk to people . Wherever she went ， people would come up to her to say a few words or to just touch her . She met the ordinary and the famous ， President Clinton included . In the last few years of her life ， before she died of cancer ， McCarty was given over 300 awards ： she was honoured bythe United Nations and received the Presidential Citizen s Medal . Despite having no real education ， she found herself with two honorary doctorates ： one from the University of SouthernMississippi and the other from Harvard University . Her generositywas clearly an inspiration to many and proof that true selflessness does exist .。
