Smart 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 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.

第三篇No one knows exactly how many disabled people there are in the world,but estimates suggest the figure is over 450 million.The number of disabled people in India alone is probably more than double the total population of Canada.In the United Kingdom,about one in ten people have some disability. Disability is not just something that happens to other people.As we get older,many of us will become less mobile,hard of hearing or have failing eyesight.Disablement can take many forms and happen at any time of life.Some people are born with disabilities.Many others become disabled as they get older. There are many progressive disabling diseases.The longer time goes on,the worse they become.Some people are disabled in accidents. Many others may have disability in the form of a mental illness.All are affected by people's attitude towards them.Disabled people face many physical barriers.Next time you go shopping or to work or visit friends,imagine what would you do if you could not get up steps,or on to buses and trains?What would you do if you could not see where you were going or could not hear the traffic?But there are other barriers:prejudice（偏见）can be even harder to break down and ignorance represents by far the greatest barrier of all.It is almost impossible for the able-bodied to fully understand what the disabled go through,so it is important to draw attention to these barriers and show that it is the individual person and their ability,not their disability,which counts.The key word in Paragraph 4 is__________.A:barriers B:disabledC:disability D:prejudice

They will a]so want to know how much money you have．In addition．the banks will require a down payment．Depending Oil which state you live in，the bank may require as much as 30%of the price of the house as a down payment．The bank will then lend you the rest of the money to buy the house.Many people are never able to buy a house because they can not save enough money for the
down payment．
