Smart Window
Windows 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 not something people typically associate with being a cutting edge 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 switch.
"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 Sweden. "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 on 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.
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. "
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.

第5题：
You are the desktop administrator for ExamSheet. Your Windows 2000 Professional computer is configured to support two monitors. You install a DOS-based application on your computer. The application uses the Windows 2000 Professional default settings Autoexec.nt and Config.nt. Your primary and secondary video adapters are both set to 32 bit color, 800 x 600 resolution, and default refresh rates. You create a shortcut for the DOS-based application on the primary monitor's desktop and use the default PIF settings. You attempt to run the DOS-based application on the primary monitor. The application opens, but the display area is scrambled. You then attempt to run the DOS-based application on the secondary monitor. The application does not open. Both monitors function correctly when you run Windows based applications. You want to be able to run the DOS-based application on either monitor. What should you do?（）
