职称英语理工类阅读理解备考之经典习题

　　Smart Window　　It took us a long time to figure out what a window really is, says Claes Granqvist.Hes a professor of solid-state physics at Uppsala University in Sweden3.Its 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 theyre stuck indoors.　　their air conditioners.Producing blasts of cold air，which can feel so refreshing，actually suck up enormous amounts of electricity in buildings around the world.　　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 its completely dark after all electricity is taken away.So applying a voltage determines whether the window looks clear or dark.　　注释：　　anywhere in between witha flip of a switch：就在开或关的一霎那。　　练习：　　as described in the first two paragraphs?　　B Windows help to save energy by letting light in.　　D Windows enable people to have contact with the outside world.　　A In the cold winter.　　C When air conditioners are turned on.　　What are smart windows，according to Paragraph 4?　　B Windows that are glazed.　　D Windows that have many layers.　　A Electricity.　　C A battery.　　What will he the benefit if the research on smart windows turns out to be successful，according to the last paragraph?　　B Windows can be as large as you want.　　D They are less expensive than traditional windows　　答案与题解：　　 A 第一段告诉我们窗户因为让阳光进入房间，并且为房间提供热源，所以节约了能源。第二段说，窗户使人们能接触外部世界。所以B、C和D都说明了窗户的重要性。第一段最后一句说，研究者正在实验能让窗户变换亮度，但并没有说已经实验成功，所以A是错误的说法，是正确选择。　　C 第四段告诉我们，多年来，科学家已研究出多种通过窗户节能的办法，而smart windows 使用的技术使窗户能变换颜色。所以C是正确选择。　　C 短文最后一段的第五句提供了答案。
