1.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.

2.According to Paragraph 2， some organizations check their systems to find out[A] whether there is any weak point.[B] what sort of data has been stolen.[C] who is responsible for the leakage.[D] how the potential spies can be located.

3.4 All organisations require trained employees. However, training can take many forms, some of which are internal to the organisation.Required:Explain what is meant by the terms:(a) Computer based training. (3 marks)

4.What will be 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.

  • 第3题：

    We can infer from Paragraph 5 that ______.（ ）

    [A] home prices has fallen down 28% compared with what's in mid-2006

    [B] many foreclosed homes have been abandoned by their former owners

    [C] home prices might fall down 28% fi'om their peak in mid-2006 in the future

    [D] more foreclosed homes have been abandoned because of the falling price


    正确答案：C
    从第五段我们可以得出__________。
    [A]房价与2006年年中相比降低了28%
    [B]许多取消抵押品赎回权的房屋被房主抛弃了
    [C]房价将来可能从2006年年中的高峰下降28%[
    D]更多取消抵押品赎回权的房屋因为房价走低被抛弃
    答案解析：[C]推理判断题。根据第五段可知，第一，2006年年中的房价是高峰；第二，全国范围的房价已经下降了18%；第三，虽然房价已经降价18%，但是可能会继续下跌10%；第四，房价继续下跌是因为大量持续不断的取消抵押品赎回权的房屋被抛向市场从而压低了房价。[A]把将来要跌的l0%算作现在已经跌的，排除；[B]、[D]把取消抵押品赎回权的房屋抛向市场误解为房主抛弃了这些房屋，排除。所以正确答案是[C]。

    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:disabled
    C:disability
    D:prejudice

    答案：A
    解析：
    第一段第一句是该段的主题句。" No one knows exactly how many disabled people there are in the world , but estimates suggest the figure is over 450 million.”说明残疾人数量很多。
    第四段第一句和第四句是该段主题句。" Disabled people face many physical barriers."',But there are other barriers:prejudice can be even harder to break down and ignorance represents by far the greatest barrier of all.”该段从实际困难和精神歧视两方面说明残疾人面临的障碍。
    文章最后一句："...it is the individual person and their ability, not their disa-bility ,which counts.”大意是“······真正重要的是残疾人的独立人格及其能力，而不是其身体上的残疾。”
    选项A、C都出现在第二段中。B是文章所呼吁的。文章最后一段说 "prejudice（偏见）can be even harder to break down and ignorance represents by far the greatest barrier of all"。残疾人所面临的障碍除了身体残疾外，还有人们的偏见和被人们忽视。所以选项D与原文不相符。
    主旨题。文章首先叙述残疾人之多和各种残疾，进而从身体和精神两方面阐述残疾人面临的障碍，并指出精神方面的障碍是最难被打破的。因此，可以推论出作者告诫我们应该正确对待残疾人。

  • 第17题：

    根据下列内容，回答211-215题。
    A house is the most expensive thing most people will ever buy．Very few people have enough money of their own to buy a house，so they have to borrow money from a bank．Borrowing moneyfrom a bank to buy a house is called“take a mortgage”．The bank usually lends money or gives a me．gage for twenty—five years．Houses are so expensive that many people nowadays have to borrow as much as$50，000．In other words，they will have a$50，000 mortgage．
    How can you get a mortgage? When you find a house you like．you go to a bank．The bank will research you financial history and decide if they think you are a good risk．They will want to know what kind of job you have，what kind of salary you make and how long you have had the job．
    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．
    What does a house mean in the United States．? __________

    A.It is a dream which many people can hardly realize
    B.It is so expensive that many people can not really buy them
    C.It is the most important property that many people try to buy
