7、that the power of creativity and intelligence can make the world a better place. For as long as I can remember, I“ve loved learning new things and solving problems. So when I sat down at a computer for the first time in seventh grade, I was hooked. It was a clunky old teletype machine and it could b

8、arely do anything compared to the computers we have today. But it changed my life. When my friend Paul Allen and I started Microsoft 30 years ago, we had a vision of “a computer on every desk and in every home“, which probably sounded a little too optimistic at a time when most computers were the si

9、ze of refrigerators. But we believed that personal computers would change the world. And they have. And after 30 years, I“m still as inspired by computers as I was back in seventh grade. I believe that computers are the most incredible tool we can use to feed our curiosity and inventiveness to help

10、us solve problems that even the smartest people couldn“t solve on their own. Computers have transformed how we learn, giving kids everywhere a window into all of the world“s knowledge. They“re helping us build communities around the things we care about and to stay close to the people who are import

11、ant to us, no matter where they are. Like my friend Warren Buffett, I feel particularly lucky to do something every day that I love to do. He calls it “tap-dancing to work“. My job at Microsoft is as challenging as ever, but what makes me “tap-dance to work“ is when we show people something new, lik

12、e a computer that can recognize your handwriting or your speech, or one that can store a lifetime“s worth of photos, and they say, “I didn“t know you could do that with a PC!“ But for all the cool things that a person can do with a PC, there are lots of other ways we can put our creativity and intel

13、ligence to work to improve our world. There are still far too many people in the world whose most basic needs go unmet. Every year, for example, millions of people die from diseases that are easy to prevent or treat in the developed world. I believe that my own good fortune brings with it a responsi

14、bility to give back to the world. My wife, Melinda, and I have committed to improving health and education in a way that can help as many people as possible. As a father, I believe that the death of a child in Africa is no less poignant or tragic than the death of a child anywhere else, and that it

15、doesn“t take much to make an immense difference in these children“s lives. I“m still very much an optimist, and I believe that progress on even the world“s toughest problems is possibleand it“s happening every day. We“re seeing new drugs for deadly diseases, new diagnostic tools, and new attention p

16、aid to the health problems in the developing world. I“m excited by the possibilities I see for medicine, for education and, of course, for technology. And I believe that through our natural inventiveness, creativity and willingness to solve tough problems, we“re going to make some amazing achievemen

Every year earthquakes are responsible for a large number of deaths and a vast amount of destruction in various parts of the world. Most of these damaging earthquakes occur either in a narrow bel

21、t which surrounds the Pacific Ocean or in a line which extends from Burma to the Alps in Europe. Some of the destruction is directly caused by the quake itself. An example of this is the collapse of buildings as a result of the quake itself. Other damage results from landslides or major fires which

22、are initiated by the quake. 2. These are about a million quakes a year. Fortunately, however, not all of them are destructive. The intensity of an earthquake is measured on the Richter Scale, which goes from upward. The highest scale recorded to date is 8.9. major damage generally occurs from quakes

23、 ranging upward from 6.0. 3. The actual cause of the quake itself is the breaking of rocks at or below the earth“s surface. This is produced by pressure which scientists believe may be due to a number of reasons, two of which are the expansion and contraction of the earth“s crust and continental dri

24、ft. 4. In order to limit the damage and to prevent some of the suffering resulting from earthquakes, scientists are working on ways to enable accurate prediction. Special instruments are used to help people record, for example, shaking of the earth. Scientists are trying to find methods that will en

25、able them to indicate the exact time, location and size of an earthquake. 5. Certain phenomena have been observed which are believed to be the signs of imminent earthquakes. These include strange behaviors of some animals, the changes in the content of mineral water, etc. The magnetic properties of

26、rocks may also display special pattern before earthquakes happen.（分数：8.00）(1).Paragraph 2 1 A. Earthquakes Forecast B. Historical Records of Earthquakes C. Intensities of Earthquakes D.

29、 for decades but hadn“t regarded plants as a producer, notes Frank Keppler, a geochemist at the Max Planck Institute for Nuclear Physics in Heidelberg, Germany. Now Keppler and his colleagues find that plants, from grasses to trees, may also be sources of the greenhouse gas. This is really surprisin

30、g, because most scientists assumed that methane production requires an oxygen- free environment. Previously, researchers had thought that it was impossible for plants to make significant amounts of the gas. They had assumed that, microbes need to be in environments without oxygen to produce methane.

31、 Methane is a greenhouse gas, like carbon dioxide. Gases such as methane and carbon dioxide trap heat in Earth“s atmosphere and contribute to global warming. In its experiments, Keppler“s team used sealed chambers that contained the same concentration of oxygen that Earth“s atmosphere has. They meas

32、ured the amounts of methane that were released by both living plants and dried plant material, such as fallen leaves. With the dried plants, the researchers took measurement at temperatures ranging from 30 to 70. At 30, they found, a gram of dried plant material released up to 3 nanograms of methane

33、 per hour. (One nanogram is a billionth of a gram.) With every 10-degree rise in temperature, the amount of methane released each hour roughly doubled. Living plants growing at their normal temperatures released as much as 370 nanograms of methane per gram of plant tissue per hour. Methane emissions

34、 tripled when living and dead plant was exposed to sunlight. Because there was plenty of oxygen available, it“s unlikely that the types of bacteria that normally make methane were involved. Experiments on plants that were grown in water rather than soil also resulted in methane emissions. That“s ano

35、ther strong sign that the gas came from the plants and not soil microbes. The new finding is an “interesting observation“, says Jennifer Y. King, a biogeochemist at the University of Minnesota in St. Paul. Because some types of soil microbes consume methane, they may prevent plant-produced methane f

36、rom reaching the atmosphere. Field tests will be needed to assess the plant“s influence, she notes.（分数：15.00）(1).What was scientists understanding of methane?（分数：3.00）A.It was produced from plants.B.It was not a greenhouse gas.C.It was produced in oxygen-free environments.D.It traps more heat than a

37、ny other greenhouse gas.(2).To test whether plants are a source of methane, the scientists created（分数：3.00）A.a oxygen-free environmentB.an environment with the same concentration of oxygen as the Earth hasC.a carbon dioxide-free environmentD.an environment filled with the greenhouse gas(3).Which sta

38、tement is true of the methane emissions of plants in the experiment?（分数：3.00）A.The lower the temperature, the higher the amount of methane emissions.B.Living plants release less methane than dried plants at the same temperature.C.When exposed to sunlight, plants stop releasing methane.D.The higher t

39、he temperature, the greater the amount of methane emissions.(4).Which of the following about methane is Not mentioned in the passage?（分数：3.00）A.Plants growing in soil release methane.B.Plants growing in water release methane.C.Soil microbes consume methane.D.Microbes in plants produce methane.(5).Wh

40、at is the beneficial point of some microbes consuming plant-produced methane?（分数：3.00）A.Methane becomes less poisonous.B.Methane is turned into a fertilizer.C.Less methane reaches the atmosphere.D.Air becomes cleaner.六、第二篇(总题数：1，分数：15.00)Smart WindowWindows not only let light in to cut down an elect

41、ricity 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 anywh

42、ere 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 f

43、eel 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 winter, cold air leaks in. When it“s hot and sunny, sunlight streams in. All of this s

44、unlight 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 r

45、esearch 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 e

46、lectricity 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,

47、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

48、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 bu

49、ildings may look different.“（分数：15.00）(1).Which of the following statements does not indicate the importance of windows as described in the first two paragraphs?（分数：3.00）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).When are windows the weak link in a building?（分数：3.00）A.In the cold winter.B.In the hot summer.C.When air conditioners are turned on.D.Both A and B.(3).What are smart windows, according to Paragraph 4?（分数：3
