  第一篇

  Smart Windows

  Windows 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 natural light are important for improving the way people feel whenthey’re stuck indoors

  Yet. 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?

  C. Theylet us have visual contact with the surrounding world.

  第二篇

  Sports Star Yao Ming

  If 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 a success, 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 means

  第三篇

  Can You Hear This?

  When something creates a sound wave in a room or anauditorium, listeners hear the sound wave directly from the source. They alsohear the reflections as the sound bounces off thewalls. floor, and ceiling. These are called the reflected wave or reverberant(反射)sound, which can be heard evenafter the sound is no longer coming from the source.

  The reverberation time of an auditorium isdetermined by the volume or interior size of the auditorium. It is alsodetermined by how well or how poorly the walls, ceiling, floor, and contents ofthe room (including the people) absorb sound. There is no ideal reverberation time,because each use of an auditorium calls for different reverberation. Speechneeds to be understood clearly; therefore rooms used for talking must have ashort reverberation time. The full-sound performance of music such ad Wagneroperas or Mahler symphonies should have a long reverberation time. The light,rapid musical passages of Bach or Mozart need a reverberation time somewherebetween.

  Acoustic problems often are caused by poorauditorium design. Smooth, curved reflecting surfaces create large reflections.Parallel (平行的)wallsreflect sound back and forth, creating a rapid, repetitive pulsing effect.Large pillars (柱)and comerscan 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 tochange the reverberation time of a room. For example, hanging large reflectors,called clouds, over the performers will allow some sound frequencies to reflectand others to pass to achieve a pleasing mixture of sound.

  41 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.

  答案:D

  42. Wagner operas and Mahler symphonieswith full-sound effect have

  A. a short reverberation time.

  B. an intermediate reverberation time.

  C. no reverberation time.

  D. along reverberation time.

  答案:D

  43. This passage suggests that a goodauditorium should

  A. get rid of all reflections.

  B. not have absorbers.

  C.achieve a pleasing mixture of sound

  D. have smooth surfaces.

  答案:C

  44. 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.

  答案:C

  45. The word" acoustic" in thelast paragraph has something to do with

  A. performance

  B.sound

  C. audience

  D. weather

  答案:B
