Underground Coal Fires a Looming CatastropheCoal burning deep underground in China, India and Indonesia is threatening the environment and human life, scientists have warned, these large-scale underground blazes cause the ground temperature to heat up and kill surrounding vegetation, produce greenhouse gases and can even ignite forest first, a panel of scientists told the annual meeting of the American Association For the Advancement of Science in Denver. The resulting release of poisonous elements like arsenic and mercury can also pollute local water sources and soils, they warned.“Coal fires are a global catastrophe,” said Associate Professor Glenn Stracher of East Georgia College in Swainsboro, USA, But surprisingly few people know about them.Coal can heat up on its own, and eventually catch fire and burn, if there is a continuous oxygen supply. The heat produced is not cause to55 disappear and under the right combinations of sunlight and oxygen, can trigger spontaneous catching fire and burning. This can occur underground, in coal stockpiles, abandoned mines or even as coal is transported. Such fires in China consume up to 200 million tones of coal per year, delegates were told. In comparison, the U.S. economy consumes about one billion tones of coal annually, said Stracher, whose analysis of the likely impact of coal fires has been accepted for publication in the International Journal of Coal Ecology. Once underway, coal fires can burn for decades, even centuries. In the process, they release large 60volumes of greenhouse gases poisonous fumes and black particles into the atmosphere.The members of the panel discussed the impact these fires may be having on global and regional climate change, cand agreed that the underground nature of the fires makes them difficult to 62protect. One of the members of the panel, Assistant Professor Paul Van Dijk of the International Institute for Geo-Information Science and Earth observation in the Netherlands, has been working with the Chinese government to detect and monitor fires in the northern regions of the country.Ultimately, the remote sensing and other techniques should allow scientists to estimate how much carbon dioxide these fires are emitting. One suggested method of containing the fires was presented by Gary Colaizzi, of the engineering firm Goodson, which has developed aheat-resistant grout (a thin mortar used to fill cracks and crevices), which is designed to be pumped into the coal fire to cut off the oxygen supply.。

During its existence,Mir was the laboratory for23,000 experiments and carried scientific equipment,estimated to be worth$80million,from many nations.3Experiments on Mir are credited with a range of findings,from the first solid measurement of the ration of heavy helium atoms in space to how to grow wheat in space.But for those favouring human space exploration,Mir showed that people could live and work in space long enough for a trip to Mars.The longest single stay in space is the437.7days that Russian astronaut Valery Polyakov spent on Mir from1994to1995.And Sergie Avdeyev accumulated747.6 days in space in three trips to the space station.The longest American stay was that of Shannon Lucid4,who spent188days aboard Mir in1996.Despite the many firsts Mir accomplished,1997was a bad year out of15for Mir.In1997,an oxygen generator caught fire. Later,the main computer system broke down,causing the station to drift several times and there were power failures.Most of these problems were repaired,with American help and suppliers,but Mir’s reputation as a space station was ruined.Mir’s setbacks are nothing,though5,when we compare them with its accomplishments.Mir was a tremendous success,which will be remembered as a milestone in space exploration and thespace station that showed long-term human habitation in space was possible.But it’s time to move on to the next generation. The International Space Station being built will be better,but it owes a great debt to Mir.31.We can infer from the passage that Mir Space StationA.Was designed to last5yearsB.Played host to7astronauts from different countries.C.Was visited only by AmericanD.Was built by Russians32.One of the contributions Mir Makes to science is thatA.helps astronauts get close to Mars.B.enables scientists to get close to Mars.C.sets a record of the longest single human stay in space.D.shows that multinational operations in space are less expensive.33.What happened to Mir in1997?A.It run out of its fund.B.Its main computer system broke down.C.It was completely damaged by fire.D.Its reputation was ruined due to power failures.34.It can infer frm the passage thatA.space exploration will not experience setbacks.B.it is different for other space station to exceed Mirs success.C.Mir is the best long-term human habitation in space in history.D.multinational space operations are getting more accomplishments.35.What is the author is attitude toward Mir?A.IndifferentB.FavourableC.IronicD.Negative第二篇Approaches to Understanding IntelligencesIt bays to be smart,but we are not all smart in the same way.You may be a talented musician,but you might not be a good reader.Each of us is different.Psychologists disagree about what is intelligence and what are talents or personal abilities.Psychologists have two different views on intelligence.Some believe there is one general intelligence.Others believe there are many different intelligences.Some psychologists say there is one type of intelligence that can be measured with IQ tests.These psychologists support their view with research that concludes that people who do well on one kind of test for mental ability do well on other tests.They do well on tests using words,numbers or pictures. They do well on individual or group tests,and written or oral tests.Those who do poorly on one test,do the same on all tests.Studies of the brain show that there is a biological basis for general intelligence.The brain of intelligence people use less energy during problem solving.The brain waves of people with higher intelligence show a quicker reaction.Some researchers conclude that differences in intelligence result from differences in the speed and effectiveness of information processing by the brain.Howard Gardner,a psychologist at the Harvard School of Education,has four children.He believes that all children are different and shouldn’t be tested by one intelligence test.Although Gardner believes general intelligence exists, he doesn’t think it tells much about the talents of a person outside of formal schooling.He think that the human mind has different intelligences.These intelligences allow us to solve the kinds of problems we are presented with in life.Each of us has different abilities within these intelligences.Gardner believes that the purpose of school should be to encourage development of all of our intelligences.Gardner says that his theory is based on biology.For example,when one part of the Brain is injured,other parts of the brain still work.People who cannot talk because of Brain damage can still sing.So,there is not just one intelligence to lose.Gardner has Identified8different kinds of intelligence;linguistic,mathematical,spatial,musical, Interpersonal,intrapersonal,body-kinesthetic(身体动觉的),and naturalistic.36.What is the main idea of this passage?A.The importance of intelligenceB.The development of intelligence testsC.How to understand intelligenceD.How to become intelligent37.Which of the following statements is true concerning general intelligence?A.Most intelligent people do well on some intelligence testsB.Intelligent people do not do well on group testsC.Intelligent people do better on written tests than on oral testsD.People doing well on one type of intelligence test do well on other tests38.Gardner believe thatA.all children are alikeB.children have different intelligencesC.children should take one intelligence testD.there is no general intelligence39.According to Gardner schools shouldA.promote development of all intelligencesB.test student's who do poorly on testsC.train students who do poorly on testsD.focus on finding the most intelligent students40.Gardner thinks that his theory has aA.musical foundationB.intrapersonal foundationC.linguistic foundationD.biological foundation第三篇Eye-tracker Lots You Drag and Drop Files with a GlanceBored of using a mouse?Soon you'll be ableto change stuff on your computer screen–and then moveit directly onto your smartphone or tablet(平板电脑)–with nothing more than a glance.A system called EyeDrop uses a head-mountedeye tracker that simultaneously records your field of view so it knows whereyouare looking on the screen.Gazing at an object–aphoto,say –and then pressing a key,selects thatobject.It can then be moved from the screen to a tablet or smartphone just byglancing at the second device,as long as the two are connected wirelessly."The beauty of using gaze to supportthis is that our eyes naturally focus on content that we want to acquire,"says Jayson Turner,who developed the system with colleagues at LancasterUniversity,UK.Turner believes EyeDrop would be useful totransfer an interactive map or contact information from a public display toyour smartphone or for sharing photos.A button needs to be used to select theobject you are looking at otherwise you end up with the"Midastouch"(点石成金)effect,whereby everything you lookat gets selected by your gaze,says Turner."Imagine if your mouse clickedon everything it pointed at,"he says.Christian Holz,a researcher inhuman-computer interaction at Yahoo Labs in Sunnyvale,California,says thesystem is a nice take on getting round this fundamental problem ofusinggaze-tracking to interact."EyeDrop solves this in a slick (灵巧的)way by combining it with input on the touch devices we carry withus most of the time anyway and using touch input as a clutchingmechanism,"he says."This now allows users to seamlessly(无缝地)interact across devices far and close in a very naturalmanner."While current eye-trackers are rather bulky,mainstream consumer devices are not too far away.Swedish firm Tobiiisdeveloping gaze-tracking technology that can be installed in laptops andtablets and is expected to be available to buy next year.And the Google Glassheadset is expected to includeeye-tracking in the future.Turner says he has also looked at how contentcan be cut and pasted or drag-and-dropped using a mix of gaze and taps on atouchscreen.The system was presented at the Conference on Mobile andUbiquitous Multimedia in Sweden,last week.41.The eye-tracker technology enables usto______A.change our computer screen.B.focus on anything that interests us.C.get a smartphone connected wirelessly.D.move an object from screen with a glance.42.Why is a button needed?______A.To minimize the cost of EyeDrop.B.To choose as many objects as possible.C.To make EyeDrop different from others.D.To select what we want.43.The word“this”in Paragraph6refers to_______A.application of gaze-tracking inhuman-computer interaction.B.interaction between human and computer.bination of gaze-tracking with input ontouch devices.D.generalization of EyeDrop system.44.Which of the following statement is trueof eye-trackers for consumer devices.______A.They are costly.B.They are available.C.They are installed in Google Glassheadset.D.They are expected to come out soon.45.What is Turner likely to study next?A.How to drag and drop with gaze and taps.B.How to present the system in public.C.How to get touch screen involved.D.How to cut and paste content from a publicdisplay.第五部分补全短文The Day a Language DiedWhen Carios Westez died at the age of76.A language died, too.Westez,more commonly known as Red Thunder Cloud,was the last speaker of the Native American language Catawba.Anyone who wants to hear the songs of the Catawba can contact the Smithsonian Institution in Washington,D.C.,where,back in the 1940s,Red Thunder Cloud recorded a series of songs for future generations.(46)They are all that is left of the Catawba language.The language that people used to speak is gone forever.We are all aware of the danger that modern industry can cause the world’s ecology(生态).However,few people are aware of the impact widely spoken languages have on other languages and ways of life.English has spread all over the world.Chinese, Spanish,Russian,and Hindi have become powerful languages as well.As these languages become more powerful,their use as tools of business and culture increases.As well,(47)When this happens,hundreds of languages that are spoken by only a few die out.Scholars believe there are around6,000 languages around the world,but more than half of them could die out within the next100years.There are many examples,Arakiis a the language of the island of Vanuatu,located in the Pacific Ocean.It is spoken by only a few older adults,so like Catawba,Araki will soon disappear.Many languages of ethiopia will have the same fate because each one has only a few speakers.(48)In the Americas,100languages,each of which has fewer than300speakers,are dying out.Red Thunder Cloud was one of the first to recognize the danger of language death and to try to do something about it. He was not actually born into the Catawba tribe,and the language was not his mother tongue.(49).The songs he sang for the Smithsonian Institution helped to make Native American music popular.Now he is gone,and the language is dead.What does it mean for the rest of us when a language disappears?When a plant,insect,or animal species dies,it is easy to understand what has been lost and to for the balance of the natural word.However,language is only a product of the mind.To be the last remaining speaker of a language,like Red Thunder,must be a peculiarly lonely destiny,almost as strange and terrible as being the last surviving member of a dying species.(50)A.Some people might want to learn some of these songs by hearts.B.Papus New Guines is an extremely rich source of different language,but more than100of them are in danger of extinction(灭绝).C.However,he was a frequent visitor to the Catawba reservation in South Carcinoma where he learned the language.D.There language don’t have many native speakers.E.For the rest of us,when a language dies,we lose the possibility of a unique way of seeing and describing the world.F.As these language become more powerful.their use as tools of business and culture increase.第六部分完形填空Underground Coal Fires——a Looming CatastropheCoal burning deep underground in China,India and Indonesia is threatening the environment and human life,scientists have warned,these large-scale underground blazes cause the ground temperature to heat up and kill surrounding vegetation,produce greenhouse gases and can even ignite forest first,a panel of scientists told the annual meeting of the American Association For the Advancement of Science in Denver.Theresulting release of poisonous elements like arsenic and mercury can also pollute local water sources and soils,they warned.“Coal fires are a global catastrophe,”said Associate Professor Glenn Stracher of East Georgia College in Swainsboro, USA,But surprisingly few people know about them.Coal can heat up on its own,and eventually catch fire and burn,if there is a continuous oxygen supply.The heat produced is not cause to disappear and under the right combinations of sunlight and oxygen,can trigger spontaneous catching fire and burning.This can occur underground,in coal stockpiles, abandoned mines or even as coal is transported.Such fires in China consume up to200million tones of coal per year,delegates were told.In comparison,the U.S.economy consumes about one billion tones of coal annually,said Stracher,whoseanalysisof the likely impact of coal fires has been accepted for publication in the International Journal of CoalEcology.Once underway,coal fires can burn for decades,even centuries.In the process,they release large volumes of greenhouse gases poisonous fumes and black particles into the atmosphere.The members of the panel discussed the impact these fires may be having on global and regional climate change,cand agreed that the underground nature of the fires makes them difficult to protect.Ultimately,the remote sensing and other techniques should allow scientists to estimatehow much carbon dioxide these fires are emitting.One suggested method of containing the fires was presented by Gary Colaizzi,of the engineering firm Goodson,which has developed a heat-resistant grout(a thin mortar used to fill cracks and crevices),which is designed to be pumped into the coal fire to cut off the oxygen supply.。

So Many 'Earths'The Milky Way (银河) contains billions of Earth-sized planets that could support 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 100 Sunlike stars could host an Earth-sized world. These are ones that would take 200 to 400 days to complete a yearly orbit.Four out of every 100 sunlike stars doesn’t sound like a big number. It would mean, however, that the Milky Way could host more than a billion Earth-sized planets with a change for life.16. The Kepler space telescope has been in service for 15 years.A. RightB. WrongC.

二、阅读理解第29篇:I'll Be Bach(B级)I'll Be BachComposer David Cope is the inventor of a computer program that writes original works of classical music. It took Cope 30 years to develop the software. Now most people can't tell the difference between music by the famous German composer J. S. Bach (1685-1750) and the Bach-like compositions from Cope's computer.It all started in 1980 in the United States, when Cope was trying to write an opera. He was having trouble thinking of new melodies, so he wrote a computer program to create the melodies. At first this music was not easy to listen to. What did Cope do? He began to rethink how human beings compose music. He realized that composers' brains work like big databases. First, they take in all the music that they have ever heard. Then they take out the music that they dislike. Finally, they make new music from what is left. According to Cope, only the great composers are able to create the database accurately, remember it, and form new musical patterns from it.Cope built a huge database of existing music. He began with hundreds of works by Bach. The software analyzed the data: it broke it down into smaller pieces and looked for patterns. It then combined the pieces into new patterns; Before long,the program could compose short Bach-like works. They weren't good, but it was a start.Cope knew he had more work todo-he had a whole opera to write. He continued to improve the software. Soon it could analyze more. complex music. He also added many other composers, including his own work, to the database.,A few years later, Cope's computer program, called "Emmy", was ready to help him with his opera. The process required a lot of collaboration between the composer and Emmy. Cope listened to the computer's musical ideas and used the ones that he liked. With Emmy, the opera took only two weeks to finish. It was called Cradle Falling, and it was a great success! Cope received some of the best reviews of his career, but no one knew exactly how he had composed the work.Since that first opera, Emmy has written thousands of compositions. Cope still gives Emmy feedback on what he likes and doesn't like of her music ,but she is doing most of the hard work of composing these days!词汇:original adj.有独创性的collaboration n.合作review n.评论feedback n.反馈注释:1.J.S.Bach:约翰?塞巴斯蒂安?巴赫(德语:Johann Sebastian Bach,1685年3月31日--1750年7月28日),巴洛克时期的德国作曲家,杰出的管风琴、小提琴、大键琴演奏家,同作曲家亨德尔和泰勒曼齐名。

Climate Change: The Long Reach1 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 fewgenerations,” he told Science News. “But the world is not ending in 2100.” For his new study, Zeebe now focuses on “slow feedbacks”. While fast 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 °C —for a 6° total increase, Zeebe reports. He also found that stow feedback events will cause global warming to persist for thousands of years after people run out of fossil fuels to burn.23. Paragraph 2 ___A__24. Paragraph 3 ____D_25.
