第一篇Smart WindowsWindows not only let light in to cut downon electricity use for lighting, but thelight coming through the window also provides heat. However, windows are notsomething people typically associate with an advanced technology. Reseachersare now working on new technologies that enable a window to quickly change fromclear to dark and anything in between easily.“It took us a long time to figure out whata window really is,”says Claes Granqvist. He’s a professor of solid-statephysics at Uppsala University in Sweden. “It contact with the outside world.You have to have visual contact with the surrounding world to feel well.” So,windows and n atural light are important for improving the way people feel whenthey’re stuck indoorsYet. windows are the weak link in abuilding when it comes to energy and temperature control. In winter cold airleaks in. When it’s hot and sunny, sunlight streams in. All of this sunlightcarries lots of heat and energy. And all of this extra heat forces people toturn on their conditioners. Producing blasts of cold air, which can feel so refreshing(使人清新的),actually sucks up enormous amountsof electricity in buildings around the world.Windows have been a major focus of energyresearch for a long time. Over the years, scientists have come up with a varietyof strategies for coating, glazing (用玻覆盖),and layeringwindows to make them more energy efficient. Smart windows go a step further.They use chromogenic (发色的)technologies which involve changes of color.Electrochromic (电致色的)windows use electricity tochange color. For example, a sheet of glass coated with thin layers of chemicalcompound such as tungsten oxide (氧化钨)works a bit like a batter. Tungsten oxides is clear when anelectric charge is applied and dark when the charge is removed, that is, whenthe amount of voltage(电压)is decreased, the window darkens until it’s completely dark afterall electricity is taken away. So applying a voltage determines whether thewindow looks clear or dark.One important feature that makes a smartwindow so smart is that it has a sort of“memory”. All it takes is a small changeof voltage to turn the window from one state to the other. Then, it stays thatway. Transits take anywhere from in10 seconds to a few minutes, depending onthe size of the window. The development of smart windows could mean thatmassive air conditioning systems may no longer be needed. “In thefuture,”Granqvist says, “our buildings may look different.”31. Which of the following of values ofwindows is NOT mentioned?A. Theylet light in to brighten the house.B. Theylet light in to heat the house.C. Theylet us have visual contact with the surrounding world.D. They let us think about the outside world.答案:D32. The expression “when it comes to “ inParagraph 3 is used toA. signalthe arrival of a guest.B. indicatethe recovery of consciousness.C. show our understanding of something.D. introduce a new aspect of a topic.答案:D33. According to Paragraph 4, smart windowsare the windows thatA. are coated.B. are glazed.C. have several layers.D.can change color.答案:D34. Whichparagraph gives an account of the way electrochromic windows……A. Paragraphs 5.B. Paragraph3.C. Paragraph4.D. Paragraphs6.答案:A35. Asmart window is smart mainly becauseA. itcan change its size.B. itcan change its structure.C. itcan change the voltage of electricity.D. it has a sort of memory.答案:D。

The group does not advocate the use of violence.A. limitB. regulateC. opposeD. support答案:DSo Many ‘Earths’life that’s the finding of a new study. It draws on date that came from NASA’s top planet-hunting telescope.A mechanical failure recently put that Kepler space telescope out of service. Kepler had played a big role in creating a census of planets orbiting some 170,000 stars. Its data have been helping astronomers predict how common planets are in our galaxy. The telescope focused on hunting planets that might have conditions similar to those on Earth.The authors of a study,published in The Proceedings of the National Academy of sciences,conclude that between 14 and 30 out of every 100 stars, with a mass and temperature similar to the Sun, may host a planet that could support life as we know it.Such a planet would have a diameter at least as large as Earth’s, but no more than twice that big . The planet also would have to orbit in a star’s habitable zone. That’s where the surface temperature would allow any water to exist as a liquid.The new estimate of how many planets might fit these conditions comes from studying more than 42,000 stars and identifying suitable worlds orbiting them. The scientists used those numbers to extrapolate (推算) to the rest of the stars that the telescope could not see .The estimate is rough, the authors admit. If applied to the solar system, it would define as habitable a zone starting as close to the Sun as Venus and running to as far away as Mars. Neither planet is Earthlike (although either might have been in the distant past). Using tighter limits, the researchers estimate that between 4 and 8 out of every 100Sunlike stars could host an Earth-sized world. These are ones that would take 200 to 400days to complete a yearly orbit.mean,however, that the Milky Way could host more than a billion Earth-sized planets with a change for life.16.

Earth is warming. Sea levels are rising. There ‘s more carbon in the air, and Arctic ice is melting faster than at any time in recorded history. Scientists who study the environment to better gauge (评估) .Earth’s future climate now argue that these changes may not reverse for a very long time .2 . People burn fossil fuels like coal and oil for energy. That burning releases carbon dioxide, a colorless gas . In the air , this gas traps heat at Earth’s surface . And the more carbon dioxide released , the more the planet warms . If current consumption of fossil fuels doesn’t slow ,the long-term climate impacts could last thousands of years-and be more severe than scientists had been expecting. Climatologist Richard Zeebe of the University of Hawaii at Manoa offers this conclusion in a new paper.3. Most climate-change studies look at what’s going to happen in the next century or so .During that time, changes in the planet’s environment could nudge(推动) global warming even higher. For example: Snow and ice reflect sunlight back into space. But as these melt,sunlight can now reach-- and warm –the exposed ground . This extra heat raises the air temperature even more, causing even more snow to melt. This type of rapid exaggeration of impacts is called a ‘fast feedback’.4. Zeebe says it’s important to look at fast feedbacks. However, he adds, they’re limited.From a climate change perspective, ‘This century is the most important time for the next few generations’, he told Science News “But the world is notfast feedback events unfold over decades or centuries, slow feedbacks can take thousands of years. Melting of continental ice sheets and the migration of plant life --- as they relocate to more comfortable areas --- are two examples of slow feedbacks.5. Zeebe gathered information from previously published studies investigating how such processes played out over thousands of years during past dramatic changes in climate. Then he came up with a forecast for the future that accounts for both slow and fast feedback processes. Climate forecasts that use only fast feedbacks predict a 4.5 degree Celsius (8.1 degree Fahrenheit) change by the year 3000. But slow feedbacks added another 1.5 ℃--for a 6 total increase, Zeebe reports. He also found that slow feedback events will cause global warming to persist for thousands of years after people run out of fossil fuels to burn.23. Paragraph 2 ________ 答案:B24.

Conservation or wasted Effort?The black robin(旅鸫)is one of the world's rarest birds.It is a small,wild bird,and it livesonly on the island of Little Mangere,off the coast of New Zealand.In 1967 there were aboutfifty black robins there;in 1977 there were fewer than ten.Energetic steps are being taken to preserve the black robin.--(47)The idea is tobuy another island nearby as a special home,a"reserve",for threatened wild life,includingblack robins.The organizers say that Little Mangere shouldthen be restocked(重新准备)withthe robin's food.Thousands of the required plants are at present being cultivated in NewZealand.Is all this concern a waste of human effort?what is reasonable and what is unreasonable?(48)Are we losing our sense ofIn the earth's long,long past hundreds of kinds of creatures have evolved,risen to a degreeof success and died out.In the long,long future there will be many new and different forms oflife.Those creatures that adapt themselves successfully to what the earth offers will survive for along time.--(49)This is nature's proven method of operation.The rule of selection--"the survival of the fittest"--is the one by which human beings havethemselves arrived on the scene.We,being ode of the most adaptable creatures the earth has yetproduced,may last longer than most.--(SO)You may take it as another rule that when,at last.human beings show signs of dying out,no othercreature will extend a paw(爪)topostpone our departure.On the contrary, we will be hurried out.Life seems to have grown too tough for black robins.I leave you to judge whether weshould try to do anything about it.A Some creatures,certain small animals,insects and birds,will almost certainly outlast(比......长久)man,for they seem even more adaptable.B Those that fail to meet the challenges will disappear early.C Detailed studies are going on,and a public appeal for money has been made.D Both represent orders in the classification of lifeE Is it any business of ours whether the black robin survives or dies out?F These are the only black robins left in the world第6部分:完形填空(第51~65题,每题1分,共15分)阅读下面的短文,文中有15处空白,每处空白给出了4个选项,请根据短文的内容从4个选项中选择1个答案,涂在答题卡相应的位置上。

The empty stretch of interstate gives way to urban congestion, and Coyne hits the brakes as a pedestrian suddenly crosses the street in front of him.But even if he hadn’t stopped in time, the woman would have been safe. She isn’t real. Neither is the town. And Coyne isn’t really driving. Coyne is demonstrating a puterized driving simulator that is helping researchers at Old Dominion University (ODU) examine how in-vehicle guidance systems affect the person behind the wheel.The researchers want to know if such systems, which give audible or written directions, are too distractingor whether any distractions are offset bythe benefits drivers get from having help findingtheir way in unfamiliar locations.“We’re looking at the performance and mental workload of drivers,” said Caryl Baldwin, the assistant psychology professor leading the research, which involves measuri ng drivers’ reaction time and brain activity as they respond to auditory and visual cues.The researchers just pleted a study of the mental workload involved in driving through different kinds of enviro____ents and heavy vs. light traffic. Preliminary resu lts show that as people “get into more challenging driving situations, they don’t have any extra mental energy to respond to something else in the enviro____ent,” Baldwin said.But the tradeoffs could be worth it, she said. This next step is to test different ways of giving drivers navigational information and how those methods change the drivers’ mental workload.“Is it best if they see a picture...that shows their position, a map kind of display?” Baldwin said.“Is it best if they hear it?” navigational s ystems now on the market give point-by-point directions that follow a prescribed route. “They’re very unforgiving,” Baldwin said. “If you miss a turn, they can almost seem to get angry.”That style of directions also can be frustrating for people who prefer more general instructions. But such broad directions can confuse drivers who prefer route directions, Baldwin said.Perhaps manufacturers should allow drivers to choose the style of directions they want, or modify systems to present some information in a way that makes sense for people who prefer the survey style, she said.Interestingly, other research has shown that about 60 percent of men prefer the survey style, while 60 percent women prefer the route style, Baldwin said. This explains the classic little thing of why men don’t like to stop and ask for directions and women do, Baldwin added.1. Which statement is true of the description in the first two paragraphs?A. If Coyne had stopped the car in time, he wouldn’t have hit the woman.B. The woman would have been knocked over, if Coyne had followed the traffic regulations.C. Coyne is not really driving so it is impossible for him to have hit the woman.D. If the woman had not crossed the street suddenly, Coyne would not have hit her.2. What do researchers want to find out, according to the third and fourth paragraphs?A. Whether or not audible or written directions are distracting.B. how long it will take the driver to respond to auditory and visual stimuli.C. How the driver perform under certain metal workload.D. All of the above.3. What are the preliminary results given in the fifth paragraph?A. Drivers are afraid of getting into challenging driving situations.B. In challenging driving situations, driversstill have extra energy to handle other things.C. In challenging driving situations, drivers do not have any additional mental energy to deal with something else.D. Drivers’ mental load remains unchanged under different situations.4. The sixth paragraph mainly state that the researchers.A. is designing a visual navigational information system.B. is designing an audio navigational information system.C. is designing an audio-visual navigational information system.D. want to determine the best ways of giving navigational information system.5. What kind of directions do men and women prefer?A. Women prefer more general directions and men prefer route directions.B. Men prefer more general directions and women prefer route direction.C. Both men and women prefer general directions.D. Both men and women prefer route directions.答案与解释 :1. C 根据第一段和第二段的内容,读者可以知道,这不是 Coyne真实的驾车经历。

One key to understanding how and by something happened is to discover when it happened.Radiocarbon dating was developed in the late 1940s by physicist Willard F. Libby at he University of Chicago. An atom of ordinary carbon,called carbon-12,has six protons(中子)and six neutrons (质子)in its nucleus. Carbon-14,or C-14,is a radioactive,unstable form of carbon that has two extra neutrons (原子核)。
It returns to a more stable form of carbon through a process called decay (衰减)。
This process involves the loss of he extra neutrons and energy from the nucleus.In Libby's radiocarbon dating technique,the weak radioactive emissions (放射)from his decay process are counted by instruments such as a radiation detector and counter. he decay rate is used to determine the proportion of C-14 atoms in the sample being dated.Carbon-14 is produced in the Earth's atmosphere when nitrogen (氮)-14,or N-14,interacts with cosmic rays (宇宙射线)。
Scientists believe since the Earth was formed,the mount of nitrogen in the atmosphere has remained constant. Consequently,C-14 formation is thought to occur at a constant rate. Now the ratio of C-14 to other carbon toms in the atmosphere is known. Most scientists agree that this ratio is useful for dating items back to at least 50,000 years.All life on Earth is made of organic molecules (分子)that contain carbon atoms coming from the atmosphere. So all living things have about the same ratio of C-14atoms to other carbon atoms in their tissues (组织)。
Once an organism (有机体)dies it tops taking in carbon in any form,and the C-14 already present begins to decay. Over time the amount of C-14 in the material decreases,and the ratio of C-14 to other carbon toms goes down. In terms of radiocarbon dating,the fewer C-14 atoms in a sample,the older that sample is.16Nowadays many scientists depend on radiocarbon for dating age-old objectsA RightB WrongC Not mentioned17The radiocarbon dating technique is only about 40 years oldA RightB WrongC Not mentioned18An atom of ordinary carbon has six protons and eight neutronsA RightB WrongC Not mentioned19Radar is used to determine the characteristics of radiocarbonA RightB WrongC Not mentioned20Radiocarbon is reliable in dating an object back to at least 50,000 years.A RightB WrongC Not mentioned21The C-14 in an organism begins to decay when it diesA RightB WrongC Not mentioned22The half-life of C-14 is about 25,000 years.A RightB WrongC Not mentioned第3部分:概括大意与完成句子(第23~30题,每题1分,共8分)下面的短文后有2项测试任务:(1)第23~26题要求从所给的6个选项中为第1~4段每段1选择个最佳标题;(2)第27~30题要求从所给的6个选项中为每个句子确定1个最佳选项。
Chimpanzees1Chimpanzees (黑猩猩)will soon be extinct (灭绝)。
If the present rate of hunting and habitat (栖息地)destruction continues,then within 20 years,there will be no chimpanzees living in the wild. But this is more than an environmental or moral tragedy (悲剧)。
