本文是2011年上海高考英语阅读最难的一篇。
文章大意说的是英国考古学家反对一项法律条文,因为据此法律条文,英国古代人的残骸将被重新掩埋,这对考古以及科学研究会造成诸多不利。
文章可以分为三个部分。
前面两段是40位英国考古学家联名上书,提出这个法律条文对考古及科学研究会造成影响的担忧。
三、四两段主要是举例说明实行这条法律的后果:会使得将来的考古发现变得没有意义。
最后三段说的是政府当局对此法律的态度和做法。
英国政府两年前对考古学家保证这条法律是临时的,但至今也未进行修正,并且,相关部门也未对残骸应该如何掩埋,掩埋于何地,以及保存怎样的掩埋记录进行详细规划。
分析:科普文一直是许多同学头疼的阅读题材。
科普文涉及的面可以很广,并且很多内容与我们同学的生活可能不是很相关,因此它也是高考阅读中最难的部分,碰到此类文章,同学务必要对文章进行分段。
理清文章逻辑关系及层次。
科普文一般都极有逻辑性。
以本文为例,文章首先提出了一个现象,然后通过举例进行后果的阐释,最后给出相关背景知识。

Human remains of ancient settlements will be reburied and lost to science under a law that threatens research into the history of humans in Britain, a group of leading archaeologists(考古学家) says. I a letter addressed to the justice secretary, Ken Clarke, 40 archaeologists write of their “deep and widespread concern” about the issue. It centers on the law introduced by the Ministry of Justice in 2008 which requires all human remains unearthed in England and Wales to be reburied within two years, regardless of their age. The decision means scientists have too little time to study bones and other human remains of national and cultural significance.“Your current requirement that all archaeologically unearthed human remains should be reburied, whether after a standard period of two years or further special extension, is contrary to basic principles of archaeological and scientific research and of museum practice,” they write.The law applies to any pieces of bone uncovered at around 400 dig sites, including the remains of 60 or so bodies found at Stonehenge in 2008 that date back to 3,000 BC. Archaeologists have been granted a temporary extension to give them more time, but eventually the bones will have to be returned to the ground.The arrangements may result in the waste of future discoveries at sites such as Happisburgh in Norfolk, where digging is continuing after the discovery of stone tools made by early humans 950,000 years ago. If human remains were found at Happisburgh, they would be the oldest in northern Europe and the first indication of what this species was. Under the current practice of the law those remains would have to be reburied and effectively destroyed.Before 2008, guidelines allowed for the proper preservation and study of bones of sufficient age and historical interest, while the Burial Act 1857 applied to more recent remains. The Ministry of Justice assured archaeologists two years ago that the law was temporary, but has so far failed to revise it.Mike Parker Pearson, an archaeologi st at Sheffield University, said: “Archaeologists have been extremely patient because we wee led to believe the ministry was sorting out this problem, but we feel that we cannot wait any longer.”The ministry has no guidelines on where or how remains should be reburied, or on what records should be kept.1. According to the passage, scientists are unhappy with the law mainly because _________.A. it is only a temporary measure on the human remainsB. it is unreasonable and thus destructive to scientific researchC. it was introduced by the government without their knowledgeD. it is vague about where and how to rebury human remains2. Which of the following statements is true according to the passage?A. Temporary extension of two years will guarantee scientists enough time.B. Human remains of the oldest species wee dug out at Happisburgh.C. Human remains will have to be reburied despite the extension of time.D. Scientists have been warned that the law can hardly be changed.3. What can be inferred about the British law governing human remains?A. The Ministry of Justice did not intend it to protect human remains.B. The Burial Act 1857 only applied to remains uncovered before 1857.C. The law on human remains hasn’t changed in recent decades.D. The Ministry of Justice has not done enough about the law.4. Which of the following might be the best title of the passage?A. New discoveries should be reburied, the government demands.B. Research time should be extended, scientists require.C. Law on human remains needs thorough discussion, authorities say.D. Law could bury ancient secrets for ever, archaeologists warn.“古代居民区的人类遗骸在一部法律之下将重新入土而与科学研究失之交臂,这部法律将会损害英国对人类历史的研究。

(完整)高考英语阅读理解科普类说明文4篇--较难(有答案)
高考英语说明文4篇1Here is an astonishing and significant fact: Mental work alone can’t makeus tire. It sounds absurd/əb'sɜːd/荒谬的. But a years ago, scientists tried to find out how long the human brain could labor without reaching a stage 阶段of fatigue /fə'tiːg/(疲劳). To the amazement of these scientists, they discovered that blood passing through the brain, when it is active, shows no fatigue at all! If we tooka drop of blood from a day laborer劳动者, we would find it fullof fatigue toxins /'tɒksɪn/ (毒素) and fatigue products. But if wetook blood from the brain of an Albert Einstein, it would show nofatigue toxins at the end of the day.So far as the brain is concerned, it can work as well and swiftly很快地at the end of eight or even twelve hours of effort as at the beginning. The brain istotally tireless. So what makes us tired?Some scientists declare that most of our fatigue comes from our mental and emotional(情绪的) attitudes. One of England’s most outstanding scientists, J.A. Hadfield, says, “The greater part of the fatigue from which we suffer is of mental origin /'ɒrɪdʒɪn/起源. In fact, fatigue of purely physical origin is rare.”Dr. Brill, a famous American scientist, goes even further. He declares, “One hundred percent of the fatigue of sitting worker in good health is due to emotional problems.”What kinds of emotions make sitting workers tired? Joy? Satisfaction?No! A feeling of being bored, anger, anxiety/æŋ'zaɪətɪ/焦虑, tenseness紧张, worry, a feeling of not being appreciated---those are the emotions that tire sitting workers. Hard work by itself seldom causes fatigue. We get tired because our emotions produce nervousness in the body.1. What surprised the scientists a few years ago?A. Fatigue toxins could hardly be found in a laborer’s blood.B. Albert Einstein didn’t feel worn after a day’s work.C. The brain could work for many hours without fatigue.D. A mental worker’s blood was filled with fatigue toxins.2. According to the author, which of the following can make sitting workers tired?A. Challenging mental work.B. Unpleasant emotions.C. Endless tasks.D. Physical labo3. What’s the author’s attitude towards the scientists’ idea?A. He agrees with them.B. He doubts them.C. He argues against them.D. He hesitates to accept them.4. We can infer from the passage that in order to stay energetic, sitting workers need to ________.A. have some good food.B. enjoy their workC. exercise regularlyD. discover fatigue toxins2They baby is just one day old and has not yet left hospital. She is quietbut alert /ə'lɜːt/(警觉). Twenty centimeters厘from her face researchershave placed a white card with two black spots on it. She stares at it carefully.A researcher removes the card and replaces it by another, this time with the spots differently spaced. As the cards change from one to the other, her gaze(凝视)starts to lose its focus — until a third, with three black spots,is presented. Her gaze returns: she looks at it for twice as long as she did at the previous card. Can she tell that the number two is different from three, just 24 hours after coming into the world?Or do newborns simply prefer more to fewer? The same experiment, but with three spots shown before two, shows the same return of interest when the number of spots changes. Perhaps it is just the newness 名,新奇? When slightly older babies were shown cards with pictures of objects (a comb, a key, an orange and so on), changing the number of objects had an effect separate from changing the objects themselves. Could it be the pattern that two things make, as opposed to three? No again. Babies paid more attention to squares moving randomly on a screen when their number changed from two to three,or three to two. The effect even crosses between senses. Babies who were repeatedly shown two spots became more excited when they then heard three drumbeats than when they heard just two; likewise (同样地)when the researchers started with drumbeats and moved to spots.5. The experiment described in Paragraph 1 is related to the baby’s__.A. sense of hearingB. sense of sightC. sense of touch D sense of smell6. Babies are sensitive to the change in______.A. the size of cardsB. the colour of picturesC. the shape of patternsD. the number of objects7. Why did the researchers test the babies with drumbeats?A. To reduce the difficulty of the experiment.B. To see howbabies recognize sounds.C. To carry their experiment further.D. To keep the babies’interest.8. Where does this text probably come from?A. Science fiction.B. Children’s literature.C. An advertisement.D.A science report3Last night’s meteor(流星) 英/'miːtɪə/ shower left many people in the community dissatisfied and demanding 苛求的;要求高的;吃力的answers. According to Gabe Rothsclild, Emerald Valley’s mayor市长, people gathered in thesuburbs /'sʌbɜːb/of the city, carrying heavy telescopes, expecting to watch the brightly burning meteors passing through the sky. What they found instead was a sky so brightene by the city’s lights that it darkened the light of the meteors passing overhead. “My family was so frustrated,” admitted town resident Duane Cosby, “We wanted to make this an unforgettable family outing, but it turned out to be a huge disappointments.”Astronomers- /ə'strɒnəmə/n. 天文学家--scientists who study stars and planets---- have beencomplaining about this problem for decades. They say that light pollution prevents them from seeing objects in the sky that they could see quite easily in the past. They call on people and the government to take measures to fightagainst it.There is yet a population besides professional and amateur /ˈæmətə(r)/美 /'æmə.tʃʊr/n. 爱好者star observers that suffers even more from light pollution. This population consists of birds, bats frogs, snakes, etc. For example, outdoor lighting severely affects migrating(迁徙的)birds. According to the International Dark-Sky Association. “100million birds a year throughout North America die in crashes 撞碎with lighted buildings and towers.”Countless more animals casualties(伤亡)result from the use of artificial lighting. Clearly, people enjoy the benefits of lighting their evenings, but some scientists think it can be harmful for humans, too. They worry that exposure to light while sleeping can increase pers on’s chances of getting cancer. Emerald Valley is only one community that is becoming aware of the negative effects of light pollution. For years, Flagstaff, Arizona/,æri'zəunə/美 /,æri'zəunə/n. 美国亚利桑那州, has enforced lighting regulations in its city in order to assist astronomers at the Lowell Observatory.英 /əb'zɜːvət(ə)rɪ/美 /əb'zɝvətɔri/n. 天文台;气象台;瞭望台Similar efforts have been made worldwide, and a movement isunderway 进行中的to remind us to turn off lights when we are not using them, so thatother creatures can share the night.9.It happened last night thatA. the city’s lights affected the meteor watchingB. the meteors flew past before being noticedC. the city light show attracted many peopleD. the meteor watching ended up a social outing10.

Saving wildlife is saving ourselvesB. Great efforts should be made to save energyC. Human activities should be environmentally friendlyD. New equipment should be introduced for space study4Almost every machine with moving parts has wheels, yet no one knows exactly when the first wheel was invented or what it was used for. We do know,however,that they existed over 5,500years ago in ancient Asia.The oldest known transport wheel was discovered in 2002 in Slovenia. It is over 5,100 years old. Evidence suggests thatwheels for transport didn't become popular for .while, though . This could be because animals did a perfectly good job of carryingfarming tools and humans around.But it could also be because of a difficult situation. While wheels need to roll on smooth surfaces, roads with smooth surfaces weren't going to be constructed until there was plenty of demand for them. Eventually, road surfaces did become smoother, but this difficult situation appeared again a few centuries later. There had been no important changes in wheel and vehicle design before the arrival of modern road design.In the mid-1700s,a Frenchman came up with a new design of road--a base layer (层)of large stones covered with a thin layer of smaller stones. A Scotsman苏格兰人improved on this design in the 1820s and a strong, lasting road surface became a reality. At around the same time, metal hubs英 /hʌb/美 /hʌb/n. 中心;毂;木片(the central part of a wheel)、came into being, followed by the Wheels were invented in 1967, sixty years after the appearance of tarmacked roads(泊油路).

Each year,the American-based group honors environmental activists from six different areas.The first three winners of the 2012 Goldman Prize are from Kenya, the Philippines and China.The Goldman Environmental Foundation says Ikal Angelei is a hero to those who live around Lake Turkana. The Kenyan woman received the award because of her efforts to stop a dam project on a river in Ethiopia. Critics say the dam will harm the lake and restrict (限制) the flow of water for people who live nearby. The Philippine island of Mindoro is home to those who depend on the area’s natural resources for food and jobs. Edwin Gariguez became concerned when a European company announced plans to mine for nickel (镍) on the island. The Roman Catholic minister said waste materials from the mining project would pollute the water and destroy the forests. So he started a campaign to stopthe project.In China, Ma June is working with businesses to clean up their pollution. He formed a group that collects information about pollution, and publishes it on the Internet.The Goldman Prize was also awarded to activists from Argentina, Russia and the United States.Sofia Gatica of Argentina is from a town where farmers commonly use pesticide (杀虫剂) products to protect soybean crops from insects. The town also has a high rate of cancer. Sofia Gatica belie ved that pesticide use was responsible for the death of her baby. She worked with other mothers to get government officials to ban the use of chemicals near populated areas.Evgenia Chirikova objects to the plans to build a road through a protected forest just outside Moscow. She has demanded that Russian officials redirectth e road away from the forest. She and her followers have been arrested for their activities. However, their campaign has gained widespread public support. The sixth winner is American Caroline Cannon—a community leader in Point Hope, Alaska. Miz Cannon is fighting to keep Arctic waters safe from oil and gasexp loration.60. We can know from the passage that ______.A. the dam project has been preventedB. the first three activists are all from AsiaC. a European company is going to dig for nickelD. Ma June is trying to stop oil and gas exploration61. From the 7th paragraph, we can know that ______.A. pesticide use accounts for a high-rate of cancerB. Sofia managed to ban the use of chemicalsC. the farmers mainly live on unpolluted productsD. the death of the baby was due to delayed treatment62. What do we know about Evgenia ChirikovaA. She plans to build a road to protect the forest.B. She is in charge of a project far away from the road.C. She persuaded the government to set her followers free.D. Her environmental action has been widely acknowledged.63. What would be the best title for the passageA. Six Advanced Individuals for Hard WorkB. Efforts to Create a Clean and Beautiful WorldC. Six Environmental Activists Win Goldman PrizeD. The Goldman Environmental Foundation Prize2SCS Global Services (SCS) has evaluated a new methodology for measuring the carbon sequestration(封存) ability of soil under the Verified(验证) Carbon Standard (VCS), a leading greenhouse gas (GHG) accounting system. The methodology, developed by The Earth Partners, will allow land managers who sequester GHGs in grasslands and farmlands to produce carbon credits for sale in the voluntary market.Managers of grasslands and farmlands can increase carbon sequestration in soil by practices such as changing grazing(放牧) practices and operating treatments designed to improve the variety and productivity of plant groups. The Earth Partners is presently piloting this methodology with farmers across seven million acres of the Palouse River and Columbia Plateau regions in the Pacific Northwest.“The VCS p rogram has achieved an important milestone in now combining grassland and rangeland carbon offset(抵消,补偿) projects," said Dr. Robert J. Hrubes, Executive Vice President of SCS."SCS looks forward to approving and verifying agricultural carbon offset projects that use this very powerful new methodology."The VM0021 Soil Carbon Quantification Methodology is based on decades of soil carbon research and testing conducted by top soil scientists. The methodology was developed by The Earth Partners and verified by Environmental Services, Inc. as well as SCS Global Services. It is the first soil carbon methodology to be approved for use under the VCS."This widely tested methodology is the first to specially deal with soils in a market," said Steven I. Apfelbaum, Chairman of Applied Ecological Services, Inc. and Director of Science with The Earth Partners. According to Apfelbaum, soils represent the second largest living sink of carbon on the planet.68. The new methodology is assessed according to .A. The Earth PartnersB. the Verified Carbon StandardC. Environmental Services, Inc.D. Applied Ecological Services, Inc.69. Carbon sequestration in soil can be strengthened by .A. selling carbon credits in the voluntary marketB. changing grazing practices and operating treatmentsC. reducing the variety and productivity of plant groupsD. decreasing farmlands in the Pacific Northwest70. Which of the following is true according to the passage?A. The VCS program proves to be successful in carbon offset projects.B. Many soil Carbon Methodologies have already been approved for use.C. The new methodology has been tested in many fields including soil.D. Soils seem to be the largest living sink of carbon on the planet.71. What is the attitude of SCS towards the new methodology?A. Opposed.B. Cautious.C. Doubtful.D. Approving.3Rainforest is home to around two-thirds of all plant and animal species found on land—in addition to millions of people who depend on them for survival—our remaining ancient forests are some of the most diverse ecosystems known to science. They are also vitally important to the health of our planet, especially when it comes to regulating the climate. But ancient forests around the world are under attack.Protecting rainforests is on the global agenda (议事日程) in a big way. Governments now recognize the importance of protecting tropical forests in order to avoid dangerous climate change, and there is now much debate. As governments try to thrash out the details of a new international agreement, expected to be signed at the end of 2009, they are discussing how best to include measures to save rainforests, and therefore address one of the majorcauses of climate change. Worldwide, forest destruction causes more greenhouse gas emissions (排放) each year than do all the trains, planes and cars on the planet. So if we are to deal with global warming, there is an urgent need to find ways to reduce the 20% of global greenhouse gas emissions caused byforest destruction each year, and to keep the remaining forests standing.We need to protect the planet’s remaining forests not only to stop climate change from getting worse, but to ensure that we can stand the impacts ofglobal warming. Healthy forests absorb and store quantities of carbon, helping to regulate temperature and generate rain. When they are destroyed, thiscarbon is released into the atmosphere. Thus keeping forests standing is botha critical part of regulating climate change and of adapting to a warmer world. To date, most of the talk has focused on how to pay for reducing deforestation (滥伐森林), rather than on how to actually go about doing it. We believe governments need to support local people to protect their environment, as we have been showing for 20 years can be a very effective way of saving rainforests.1. The best title for the passage is .A. Rainforest and Climate ChangeB. Strategies on Protecting RainforestC. Serious Deforestation to RainforestD. Present Situation of Rainforest2. From the first paragraph we can infer that .A. we have little rainforest left until nowB. the ancient forests are being destroyedC. rainforest control the planet in many waysD. Rainforest is home to all plants and animals on earth3. The underlined part “thrash out” in the second paragraph means.A. try to understandB. come up withC. hide awayD. havea thorough discussion4. Greenhouse gas emissions caused by forest destruction .A. are the same amount by transport on earthB. take 20% of global greenhouse gas emissionsC. can be avoided by setting measures onlyD. have nothing to do with climate change5. From the text we can learn that healthy forest .A. can keep us healthy and happyB. can increase the effect from global warmingC. can be helpful in adjusting the temperatureD. can give out large amounts of carbon4Rivers may be a significant source of the greenhouse gas nitrous oxide (一氧化二氮), scientists now find.Their calculation suggests that across the globe the waterways contributethree times the amount of nitrous oxide to the atmosphere as had beenestimated by the International Panel on Climate Change (IPCC), the United Nations scientific body charged with reviewing climate change research. They found that the amount of nitrous oxide produced in streams is related to human activities that release nitrogen (氮) into the environment, such as fertilizer use and sewage discharges.“Human activities, including fossil fuel combustion and intensive agriculture, ha ve increased the availability of nitrogen in the environment,” said Jake Beaulieu of the University of Notre Dame and the U.S. Environmental Protection Agency in Cincinnati, Ohio, and lead author of the paper published this weekin the journal Proceedings of the National Academy of Sciences.“Much of this nitrogen is transported into river and stream networks,” Beaulieu said. There, microbes (微生物) convert the nitrogen into nitrous oxide (also called laughing gas) and an inert gas called dinitrogen (二氮). The finding is important, the researchers say, because nitrous oxide is a powerful greenhouse gas that contributes to climate change and destruction of the stratosphere’s ozone layer, which protects us from the sun’s harmful ultraviolet (紫外线) radiation. Compared with carbon dioxide, nitrous oxide is 300-fold more powerful in terms of its warming potential, though carbon dioxide is a far more common greenhouse gas. Scientists estimate nitrous oxide accounts for about 6 percent of human-induced climate change.Beaulieu and colleagues measured nitrous oxide production rates in 72 streams. When summed across the globe, the results showed rivers and streams are the source of at least 10 percent of human-caused nitrous oxide emissions to the atmosphere.“Changes in agricultural and land-use practices that result in less nitrogen being delivered to streams would reduce nitrous oxide emissions from river networks,” Beaulieu said.1. From the second paragraph we can learn .A. actually rivers give off much more nitrous oxide than expectedB. scientists’ calculation is totally wrongC. human activities release nitrous oxide in to the riversD. there is no nitrogen in fertilizer2. Which of the following is NOT the source of nitrogenA. Fertilizer use.B. Sewage discharges.C. Fossil fuel combustion.D. Climate change.3. Nitrous oxide is a powerful greenhouse gas because .A. it can protect us from the sun’s harmful ultraviolet radiationB. it is to blame for most of human-induced climate changeC. it is a far more common greenhouse gasD. it has much more warming potential than carbon dioxide4. What does the passage mainly tells usA. Rivers may be a source of the greenhouse gas nitrous oxide.B. It’s human activities that release nitrogen int o the environment.C. How to reduce nitrous oxide emissions from river networksD What to do with the climate change caused by nitrous oxide.5The Maldives faces the threat of extinction from rising sea levels, but the government said on Thursday it was looking to the future with plans to build homes and a golf course that float.An increase in sea levels of just 18 to 59 centimeters would make the Maldives—a nation of tiny coral islands in the Indian Ocean—virtually uninhabitable by 2100, the UN’s cli mate change panel has warned.President Mohamed Nasheed has vowed a fight for survival, and last month he signed a deal with a Dutch company to study proposals for a floating structure that could support a conference centre, homes and an 18-hole golf course.“It is still early stages and we are awaiting a report on the practicality,”a government official who declined to be named said.The company, Dutch Docklands, is currently building floating developments in the Netherlands and Dubai. There was no immediate comment from the firm butits website said it undertook projects that make “land from water by providing large-scale floating constructions to create similar conditions as on land”.The Maldives began to work on an artificial island known as the Hulhumale near the crowded capital island of Male in 1997 and more than 30,000 people havebeen settled there to ease congestion. The city, which has a population of 100,000, is already protected from rising sea levels by a 30-million-dollar sea wall, and the government is considering increasingly imaginative ways to combat climate change.Nasheed, who staged the world’s first underwater cabinet meeting in Octoberto highlight his people’s serious and difficult situation, has even spoken of buying land elsewhere in the world to enable Maldivians to relocate if their homes are completed covered.He has also promised to turn his nation into a model for the rest of the world by becoming “carbon neutral” by 2020. His plan involves ending fossil fuel use and pow ering all vehicles and buildings from “green” sources such as burning coconut husks.1. Why do you think Mohamed Nasheed chose Dutch DocklandsA. Because it has experience in building floating structure.B. Because it has a good fame throughout the world.C. Because it charged much less than other companies.D. Because it supports building floating structures in the world.2. The Hulhumale was built with the purpose of .A. attracting more visitorsB. making it a new capitalC. making the capital less crowdedD. fighting against climate change3. According to the last two paragraphs, Nasheed is a person who .A. has succeeded in buying land abroadB. is more than well-knownC. has thought more for his nationD. has stopped using fossil fuel4. The underlined word “vowed” in paragraph 3 can be replaced by.A. endedB. promisedC. failedD. weighed6PLAYA GRANDE, COSTA RICA This resort town was long known for Leatherback Sea Turtle (棱皮龟) national Park, nightly turtle beach tours and even a seaturtle museum. However, on a beach where dozens of turtles used to nest on a given night, scientists spied only 32 leatherbacks all of last year.With leatherbacks threatened with extinction (灭绝), Playa Grande’s turtle museum was abandoned three years ago and now sits among a sea of weeds. And the beachside ticket office for turtle tours was washed away by a high tide inSeptember. “We do not promote that as a turtle tourism destination any more because we realize there are far too few turtles to please,” said Alvaro Fonseca, a park ranger (管理员).Even before scientists found temperatures going up over the past decade, sea turtles were threatened by beach development, drift net fishing and Costa Ricans interest in eating turtle eggs. But climate change may cause the most serious harm to an animal that has lived in the Pacific for 150 million years. Sea turtles are sensitive to numerous effects of warming. They feed on reefs, which are dying in hotter seas. They lay eggs on beaches that are being covered by rising seas and more violent waves.More uniquely their gender (性别) is determined, not by genes but by theegg’s temperature during development. Small rises in beach temperatures can result in ail-female populations, obviously problematic for survival. If the sand around the eggs hits 30 degrees Celsius, the gender balance shits to females: at about 32 degrees they are all female. Above 34, you get boiled eggs.On some nesting beaches, scientists are artificially cooling nests with shade or irrigation and trying to protect broader areas of coastal property from development to ensure that turtles have a place to nest as the seas rise.5. Why does the resort town stop promoting it’s turtle tourismA. It decides no t to disturb the turtles’ normal life.B. Tourists have lost interest in watching turtles.C. There are only very few turtles now.D. The turtle museum was destroyed by a high tide.6. Which of the following is the major factor in the turtles endangermentA. The locals eating habit.B. Drift net fishing.C. Beach development.D. Global warming.7. We learn from the last paragraph that scientists .A. are doing research on the sea riseB. are moving turtles to new homesC. are protecting turtles’ nestsD. are getting rid of sea weeds8. The passage intends to .A. introduce a special kind of sea turtleB. explain the mystery of turtles’ eggsC. show the dangers a certain kind of turtle is facingD. attract more visitors to a sea turtle museum7Sometimes, the simplest ideas are the best. For example, to absorb heat from the sun to heat water, you need large, flat, black surfaces. One way to dothat is to build those surfaces specially, on the roofs of buildings. But why go to all that trouble when cities are full of black surfaces already, in the form of asphalt(柏油) roadsTen years ago, this thought came into the mind of Arian de Bondt, a Dutch engineer. He finally persuaded his boss to follow it up. The result is that their building is now heated in winter and cooled in summer by a system that relies on the surface of the road outside.The heat-collector is a system of connected water pipes. Most of them run from one side of the street to the other, just under the asphalt road. Some, however, dive deep into the ground.When the street surface gets hot in summer, water pumped through the pipes picks up this heat and takes it underground through one of the diving pipes. At a depth of 100 metres lies a natural aquifer(蓄水层) into which several heat exchangers(交换器) have been built. The hot water from the street runs through these exchangers, warming the ground-water, before returning to the surface through another pipe. The aquifer is thus used as a heat store.In winter, the working system is changed slightly. Water is pumped through the he at exchangers to pick up the heat stored during summer. This water goes into the building and is used to warm the place up. After performing that task, it is pumped under the asphalt and its remaining heat keeps the road free of snow and ice.1. Which of the following is true according to the first two paragraphsA. Arian de Bondt got his idea from his boss.B. Large, flat, black surfaces need to be built in cities.C. The Dutch engineer’s system has been widely used.D. Heat can also be collected from asphalt roads.2. For what purpose are the diving pipes usedA. To absorb heat from the sun.B. To store heat for future use.C. To turn solar energy into heat energy.D. To carry heat down below the surface.3. From the last paragraph we can learn that .A. some pipes have to be re-arranged in winterB. the system can do more than warming up the buildingC. the exchangers will pick up heat from the street surfaceD. less heat may be collected in winter than in summer4. What is most likely to be discussed in the paragraph that followsA. What we shall do if the system goes wrong.B. What we shall do if there are no asphalt roads.C. How the system cools the building in summer.D. How the system collects heat in spring and autumn.8We already know the fastest, least expensive way to slow climate change: Use less energy. With a little effort, and not much money, most of us could reduce our energy diets by 25 percent or more—doing the Earth a favor while also helping our wallets.Not long ago, my wife, PJ, and I tried a new diet—not to lose a little weight but to answer an annoying question about climate change. Scientists have reported recently that the world is heating up even faster than predicted only a few years ago, and that the consequences could be severe if we don’t keep) and other greenhouse gases reducing emissions(排放) of carbon dioxide(CO2that are trapping heat in our atmosphere.We decided to try an experiment. For one month we recorded our personal. We wanted to see how much we could cut back, so we went on a emissions of CO2a strict die t. The average US household(家庭) produces about 150 pounds of CO2 day by doing common-place things like turning on air-conditioning or driving cars. That’s more than twice the European average and almost five times the global average, mostly because Americans drive more and have bigger houses. But how much should we try to reduceFor an answer, I checked with Tim Flannery, author of The Weather Makers:How Man Is Changing the Climate and What It Means for Life on Earth. In his book, he had challenged readers to make deep cuts in personal emissions to keep the world from reaching extremely important tipping points, such as the melting(融化) of the ice sheets in Greenland or West Antarctica. “To stay below that point, we need to reduce COemissions by 80 percent, “ he said.2Good advice, I thought. I’d opened our bedroom windows to let in the wind. We’d gotten so used to keeping our air-conditioning going around the clock. I’d almost forgotten the windows even opened. We should not let this happen again. It’s time for us to change our hab its if necessary.1. Why did the author and his wife try a new dietA. To take special kinds of food.B. To respond to climate change.C. To lose weight.D. To improve their health.2. The underlined words “tipping points” most probably refer to “”.A. freezing pointsB. burning pointsC. melting pointsD. boiling points3. It can be inferred from the passage that .A. it is necessary to keep the air-conditioning on all the timeB. it seems possible for every household to cut emissions of CO2a monthC. the average US household produces about 3, 000 pounds of CO2a month D. the average European household produces about 1, 000 pounds of CO24. Which of the following would be the best title for this passageA. Saving Energy Starts at HomeB. Changing Our Habits Begins at WorkC. Changing Climate Sounds ReasonableProves DifficultD. Reducing Emissions of CO29The need to feed a growing population is putting much pressure on the world’s supply of water. With 97% of the world’s w ater too salty to be drunk or used in agriculture, the worldwide supply of water needs careful management, especially in agriculture. Although the idea of a water shortage (短缺) seems strange to someone fortunate enough to live in a high rainfall country, many of the world’s agricultural industries experience constant water shortages. Although dams can be built to store water for agricultural use in dry areas and dry seasons, the costs of water redistribution (重新分配) are very high. Not only is there the cost of the engineering itself, but there is also an environmental cost to be considered. Where valleys (山谷) are flooded to create dams, houses are lost and wildlife homes destroyed. Besides, water may flow easily through pipes to fields, but it cannot be transported from one side of the world to the other. Each country must therefore rely on the management of its own water to supply its farming requirements.This is particularly troubling for countries with agricultural industries in areas dependent on irrigation (灌溉). In Texas, farmers’ overuse of irrgation water has resulted in a 25% reduction of the water stores. In the Central Valley area of southwestern USA, a huge water engineering project provided water for farming in dry valleys, but much of the water use has been poorly managed.Saudi Arabia’s attempts to grow wheat in desert areas have seen the pumpingo f huge quantities of irrigation water from underground reserves. Because there is no rainfall in these areas, such reserves can only decrease, and it is believed that fifty years of pumping will see them run dry.1. From the first two paragraphs we learn that .A. much of the world’s water is available for useB. people in high rainfall countries feel luckyC. the costs of water redistribution should be consideredD. water can be easily carried through pipes across the world2. Which of the following is trueA. The water stores in Texas have been reduced by 75%.B. Most industries in the world suffer from water shortages.C. The underground water in Saudi Arabia might run out in 50 years.D. Good management of water use resulted from the project in the Central Valley.3. What is most likely to be discussed in the paragraph that followsA. Steps to improving water use management.B. Ways to reduce the costs of building dams.C. Measures to deal with worldwide water shortages.D. Approaches to handling the pressure on water supply.4. The text is mainly about .A. water supply and increasing populationB. water use management and agricultureC. water redistribution and wildlife protectionD. water shortages and environmental protection10Businesses are witnessing a difficult time, which has in turn produced influence on consumers’ desire to go green. However, shopper s are still laying stress on environmental concerns.Two thirds of customers say that environmental considerations inform their purchases to the same degree as they did a year ago, while more than a quarter say that they are now even better aware of the environmental effect on what they buy.This may help to influence how shops store goods on their shelves. And the companies should still make efforts to become more environmentally friendly. Two out of three people think it is important to buy from environmentally responsible companies, with about one in seven saying that they had even decided to take their custom elsewhere if they felt a company’s environmental reputation was not good enough.Harry Morrison, chief executive (主管) of the Carbon Trust, sympathizes: “I understand this situation where survival is very important now. But f rom environmental considerations, the clock is ticking—we don’t have much time. In addition, cutting carbon has an immediate effect as costs drop and a medium-term benefit for the brand.”Larger companies have an extra motivation to look at reducing their carbon footprint, as new rules next year will require businesses to buy carbon allowances to make up for their emissions (排放). Those that have taken early action will have a head start. More than two thirds of consumers are not clear about which companies are environmentally responsible. This suggests that firms that are able to relay clearly their message to the public will be in a pole position to attract shoppers.。
高考英语 阅读理解 科普类说明文4篇 -- 较难 (有答案)
高考英语说明文4篇1Here is an astonishing and significant fact: Mental work alone can’t makeus tire. It sounds absurd/əb'sɜːd/荒谬的. But a years ago, scientists tried to find outhow long the human brain could labor without reaching a stage 阶段of fatigue /fə'tiːg/(疲劳). To the amazement of these scientists, they discovered that blood passing through the brain, when it is active, shows no fatigue at all! If we tooka drop of blood from a day laborer劳动者, we would find it full offatigue toxins /'tɒksɪn/ (毒素) and fatigue products. But if we tookblood from the brain of an Albert Einstein, it would show no fatiguetoxins at the end of the day.So far as the brain is concerned, it can work as well and swiftly很快地at the end of eight or even twelve hours of effort as at the beginning. The brain is totally tireless. So what makes us tired?Some scientists declare that most of our fatigue comes from our mentaland emotional(情绪的) attitudes. One of England’s most outstanding scientists, J.A. Hadfield, says, “The greater part of the fatigue from which wesuffer is of mental origin /'ɒrɪdʒɪn/起源. In fact, fatigue of purely physical origin is rare.”Dr. Brill, a famous American scientist, goes even further. He declares, “One hundred percent of the fatigue of sitting worker in good health is due to emotional problems.”What kinds of emotions make sitting workers tired? Joy? Satisfaction?No! A feeling of being bored, anger, anxiety/æŋ'zaɪətɪ/焦虑, tenseness紧张, worry, a feeling of not being appreciated---those are the emotions that tire sitting workers. Hard work by itself seldom causes fatigue. We get tired because our emotions produce nervousness in the body.1. What surprised the scientists a few years ago?A. Fatigue toxins could hardly be found in a laborer’s blood.B. Albert Einstein didn’t feel worn after a day’s work.C. The brain could work for many hours without fatigue.D. A mental worker’s blood was filled with fatigue toxins.2. According to the author, which of the following can make sitting workers tired?A. Challenging mental work.B. Unpleasant emotions.C. Endless tasks.D. Physical labo3. What’s the author’s attitude towards the scientists’ idea?A. He agrees with them.B. He doubts them.C. He argues against them.D. He hesitates to accept them.4. We can infer from the passage that in order to stay energetic, sitting workers need to ________.A. have some good food.B. enjoy their workC. exercise regularlyD. discover fatigue toxins2They baby is just one day old and has not yet left hospital. She is quietbut alert /ə'lɜːt/(警觉). Twenty centimeters厘from her face researchers have placed a white card with two black spots on it. She stares at it carefully.A researcher removes the card and replaces it by another, this time with the spots differently spaced. As the cards change from one to the other, hergaze(凝视)starts to lose its focus — until a third, with three black spots,is presented. Her gaze returns: she looks at it for twice as long as she did atthe previous card. Can she tell that the number two is different from three,just 24 hours after coming into the world?Or do newborns simply prefer more to fewer? The same experiment, butwith three spots shown before two, shows the same return of interest whenthe number of spots changes. Perhaps it is just the newness 名,新奇? When slightly older babies were shown cards with pictures of objects (a comb, a key, an orange and so on), changing the number of objects had an effect separate from changing the objects themselves. Could it be the pattern that two things make, as opposed to three? No again. Babies paid more attention to squares moving randomly on a screen when their number changed from two to three,or three to two. The effect even crosses between senses. Babies who were repeatedly shown two spots became more excited when they then heard three drumbeats than when they heard just two; likewise (同样地)when the researchers started with drumbeats and moved to spots.5. The experiment described in Paragraph 1 is related to the baby’s__.A. sense of hearingB. sense of sightC. sense of touch D sense of smell6. Babies are sensitive to the change in______.A. the size of cardsB. the colour of picturesC. the shape of patternsD. the number of objects7. Why did the researchers test the babies with drumbeats?A. To reduce the difficulty of the experiment.B. To see howbabies recognize sounds.C. To carry their experiment further.D. To keep the babies’interest.8. Where does this text probably come from?A. Science fiction.B. Children’s literature.C. An advertisement.D.A science report3Last night’s meteor(流星) 英/'miːtɪə/ shower left many people in the community dissatisfied and demanding 苛求的;要求高的;吃力的answers. According to Gabe Rothsclild, Emerald Valley’s mayor市长, people gathered in the suburbs /'sʌbɜːb/ of the city, carrying heavy telescopes, expecting to watch the brightly burning meteors passing through the sky. What they found instead was a sky so brighteneby the city’s lights that it darkened the light of the meteors passing overhead.“My family was so frustrated,” admitted town resident Duane Cosby, “We wanted to make this an unforgettable family outing, but it turned out to be ahuge disappointments.”Astronomers- /ə'strɒnəmə/n. 天文学家--scientists who study stars and planets----have beencomplaining about this problem for decades. They say that light pollution prevents them from seeing objects in the sky that they could see quite easily in the past. They call on people and the government to take measures to fight against it.There is yet a population besides professional and amateur /ˈæmətə(r)/美 /'æmə.tʃʊr/n. 爱好者star observers that suffers even more from light pollution. This population consists of birds, bats frogs, snakes, etc. For example, outdoor lighting severely affects migrating(迁徙的)birds. According to the International Dark-Sky Association. “100million birds a year throughoutNorth America die in crashes 撞碎with lighted buildings and towers.”Countless more animals casualties(伤亡)result from the use of artificial lighting. Clearly, people enjoy the benefits of lighting their evenings, butsome scientists think it can be harmful for humans, too. They worry that exposure to light while sleeping can increase pers on’s chances of getting cancer. Emerald Valley is only one community that is becoming aware of the negative effects of light pollution. For years, Flagstaff, Arizona/,æri'zəunə/美 /,æri'zəunə/n. 美国亚利桑那州, has enforced lighting regulations in its city in order to assist astronomers at the Lowell Observatory.英 /əb'zɜːvət(ə)rɪ/美 /əb'zɝvətɔri/n. 天文台;气象台;瞭望台Similar efforts have been made worldwide, and a movement is underway 进行中的to remind us to turn off lights when we are not using them, so that other creatures can share the night.9.It happened last night thatA. the city’s lights affected the meteor watchingB. the meteors flew past before being noticedC. the city light show attracted many peopleD. the meteor watching ended up a social outing10.

Saving wildlife is saving ourselvesB. Great efforts should be made to save energyC. Human activities should be environmentally friendlyD. New equipment should be introduced for space study4Almost every machine with moving parts has wheels, yet no one knows exactly when the first wheel was invented or what it was used for. We do know,however,that they existed over 5,500years ago in ancient Asia.The oldest known transport wheel was discovered in 2002 in Slovenia. It is over 5,100 years old. Evidence suggests thatwheels for transport didn't become popular for .while, though . Thiscould be because animals did a perfectly good job of carryingfarming tools and humans around.But it could also be because of a difficult situation. While wheels need to roll on smooth surfaces, roads with smooth surfacesweren't going to be constructed until there was plenty of demandfor them. Eventually, road surfaces did become smoother, but this difficult situation appeared again a few centuries later. There hadbeen no important changes in wheel and vehicle design before thearrival of modern road design.In the mid-1700s,a Frenchman came up with a new design ofroad--a base layer (层)of large stones covered with a thin layer ofsmaller stones. A Scotsman苏格兰人improved on this design in the 1820s and a strong, lasting road surface became a reality.

Against the supposition that forest fires in Alaska, Canada and Siberia warm the climate, scientists have discovered that cooling may occur in areas where burnt trees allow more snow to mirror more sunlight into space.This finding suggests that taking steps to prevent northern forest to limit the release of greenhouse gases may warm the climate in northern regions. Usually large fires destroyed forestsin these areas over the past decade. Scientists predict that with climate warming, fires may occur more frequently over next several centuries as a result of a longer fire season. Sunlight taken inby the earth tends to cause warming, while heat mirrored back into space tends to cause cooling.This is the first study to analyze all aspects of how northern fires influence climate. Earlier studies by other scientists have suggested that fire in northern regions speed up climate warming because greenhouse gases from burning trees and plants are released into the atmosphere and thus trap heat.Scientists found that right after the fire, large amounts of greenhouse gases entered the atmosphere and caused warming. Ozone (臭氧) levels increased, and ash from the fire fell on far-off sea ice, darkening the surface and causing more radiation from the sun to be taken in. The following spring, however, the land within the area of the fire was brighter than before the fire, because fewer trees covered the ground. Snow on the ground mirrored more sunlight back into space, leading to cooling."We need to find out all possible ways to reduce the growth of greenhouse gases in the atmosphere." Scientists tracked the change in amount of radiation entering and leaving the climate system as a result of the fire, and found a measurement closely related to the global air temperature. Typically, fire in northern regions occurs in the same area every 80 to 150 years. Scientists, however, found that when fire occurs more frequently, more radiation is lost from the earth and cooling results. Specifically, they determined when fire returns 20 years earlier than predicated, 0.5 watts per square meter of area burned are soaked up by the earth from greenhouse gases, but 0.9 watts per square meter will be sent back into space. The net effect is cooling. Watts are used to measure the rate at which energy is gained or lost from the earth.(1)According to the new findings, taking steps to prevent northern forest fires may ________.A. result in a warming climateB. cause the forest fires to occur more frequentlyC. lead to a longer fire seasonD. protect the forests and the environment there(2)The following are all the immediate effects after a forest fire EXCEPT ________.A. large amounts of greenhouse gases enter the atmosphereB. the levels of ozone which is a type of oxygen increaseC. snow on the ground mirrors more sunlight back into spaceD. ashes from the fire fall on the ice surface and take in more radiation from the sun(3)Earlier studies about northern forest fires ________.A. analyze all aspects of how northern fires influence climateB. indicate that forest fires will pollute the atmosphereC. suggest that people should take measures to protect the environmentD. suggest that the fires will speed up climate warming(4)The underlined phrase "soak up" in the last paragraph most probably means ________.A. releasedB. absorbedC. createdD. distributed(5)From the passage we can draw a conclusion that forest fires in Alaska, Canada and Siberia may ________.A. warm the climate as the supposition goesB. allow more snow to reflect more sunlight into space and thus cool the climateC. destroy large areas of forests and pollute the far-off sea iceD. help to gain more energy rather than release more energy【答案】(1)A(2)C(3)D(4)B(5)B【解析】【分析】本文是一篇说明文,介绍了阿拉斯加、加拿大和西伯利亚的森林大火使气候变暖,科学家们已经发现,在燃烧的树木允许更多的雪将更多的阳光反射到太空的地区可能会发生冷却。

.2014年高考英语二轮复习阅读理解拉分题(较难题目)特训:节能环保类1The Goldman Environmental Foundation recently recognized a group of individuals (个体) for their efforts toprotect the environment. Each year, the American-based group honors environmental activists from six differentareas.The first three winners of the 2012 Goldman Prize are from Kenya, the Philippines and China.The Goldman Environmental Foundation says Ikal Angelei is a hero to those who live around Lake Turkana. TheKenyan woman received the award because of her efforts to stop a dam project on a river in Ethiopia. Critics saythe dam will harm the lake and restrict (限制) the flow of water for people who live nearby.The Philippine island of Mindoro is home to those who depend on the area's natural resources for food and jobs.Edwin Gariguez became concerned when a European company announced plans to mine for nickel (镍) on theisland. The Roman Catholic minister said waste materials from the mining project would pollute the water anddestroy the forests. So he started a campaign to stop the project.In China, Ma June is working with businesses to clean up their pollution. He formed a group that collectsinformation about pollution, and publishes it on the Internet.The Goldman Prize was also awarded to activists from Argentina, Russia and the United States.Sofia Gatica of Argentina is from a town where farmers commonly use pesticide (杀虫剂) products to protectsoybean crops from insects. The town also has a high rate of cancer. Sofia Gatica believed that pesticide use wasresponsible for the death of her baby. She worked with other mothers to get government officials to ban the use ofchemicals near populated areas.Evgenia Chirikova objects to the plans to build a road through a protected forest just outside Moscow. She hasdemanded that Russian officials redirect the road away from the forest. She and her followers have been arrestedfor their activities. However, their campaign has gained widespread public support.The sixth winner is American Caroline Cannon—a community leader in Point Hope, Alaska. Miz Cannon isfighting to keep Arctic waters safe from oil and gas exploration.60. We can know from the passage that ______.A. the dam project has been preventedB. the first three activists are all from AsiaC. a European company is going to dig for nickel..D. Ma June is trying to stop oil and gas exploration61. From the 7th paragraph, we can know that ______.A. pesticide use accounts for a high-rate of cancerB. Sofia managed to ban the use of chemicalsC. the farmers mainly live on unpolluted productsD. the death of the baby was due to delayed treatment62. What do we know about Evgenia Chirikova?A. She plans to build a road to protect the forest.B. She is in charge of a project far away from the road.C. She persuaded the government to set her followers free.D.

Six Environmental Activists Win Goldman PrizeD. The Goldman Environmental Foundation Prize2SCS Global Services (SCS)has evaluated a new methodology for measuring the carbon sequestration (封存)ability of soil under the Verified(验证)Carbon Standard (VCS), a leading greenhouse gas (GHG)accountingsystem. The methodology, developed by The Earth Partners, will allow land managers who sequester GHGs ingrasslands and farmlands to produce carbon credits for sale in the voluntary market.Managers of grasslands and farmlands can increase carbon sequestration in soil by practices such as changinggrazing(放牧)practices and operating treatments designed to improve the variety and productivity of plantgroups. The Earth Partners is presently piloting this methodology with farmers across seven million acres of thePalouse River and Columbia Plateau regions in the Pacific Northwest.“The VCS program has achieved an important milestone in now combining grassland and rangeland carbon offset(抵消,补偿)projects, said Dr. Robert J. Hrubes, Executive Vice President of SCS.SCS looks forward toapproving and verifying agricultural carbon offset projects that use this very powerful new methodology...The VM0021 Soil Carbon Quantification Methodology is based on decades of soil carbon research and testingconducted by top soil scientists. The methodology was developed by The Earth Partners and verified by Environmental Services, Inc. as well as SCS Global Services. It is the first soil carbon methodology to be approvedfor use under the VCS.This widely tested methodology is the first to specially deal with soils in a market, said Steven I. Apfelbaum,Chairman of Applied Ecological Services, Inc. and Director of Science with The Earth Partners. According toApfelbaum, soils represent the second largest living sink of carbon on the planet.68. The new methodology is assessed according to.A. The Earth PartnersB. the Verified Carbon StandardC.

Governments now recognize theProtecting rainforests is on the global agenda (议事日程importance of protecting tropical forests in order to avoid dangerous climate change, and there is now much debate.As governments try to thrash out the details of a new international agreement, expected to be signed at the end of2009, they are discussing how best to include measures to save rainforests, and therefore address one of the major) each year causes of climate change. Worldwide, forest destruction causes more greenhouse gas emissions (排放than do all the trains, planes and cars on the planet. So if we are to deal with global warming, there is an urgentneed to find ways to reduce the 20% of global greenhouse gas emissions caused by forest destruction each year,and to keep the remaining forests standing.We need to protect the planet's remaining forests not only to stop climate change from getting worse, but to ensurethat we can stand the impacts of global warming. Healthy forests absorb and store quantities of carbon, helping toregulate temperature and generate rain. When they are destroyed, this carbon is released into the atmosphere. Thuskeeping forests standing is both a critical part of regulating climate change and of adapting to a warmer world.), rather than on how to 滥伐森林To date, most of the talk has focused on how to pay for reducing deforestation (actually go about doing it.

They found that the amount of nitrous oxideproduced in streams is related to human activities that release nitrogen (氮) into the environment, such as fertilizeruse and sewage discharges.“Human activities, including fossil fuel combustion and intensive agriculture, have increased the availability ofnitrogen in the environment,”said Jake Beaulieu of the University of Notre Dame and the U.S. EnvironmentalProtection Agency in Cincinnati, Ohio, and lead author of the paper published this week in the journal Proceedingsof the National Academy of Sciences.“Much of this nitrogen is transported into river and stream networks,”Beaulieu said. There, microbes (微生物)convert the nitrogen into nitrous oxide (also called laughing gas) and an inert gas called dinitrogen (二氮)...The finding is important, the researchers say, because nitrous oxide is a powerful greenhouse gas that contributesto climate change and destruction of the stratosphere's ozone layer, which protects us from the sun's harmfulultraviolet (紫外线) radiation. Compared with carbon dioxide, nitrous oxide is 300-fold more powerful in terms ofits warming potential, though carbon dioxide is a far more common greenhouse gas. Scientists estimate nitrousoxide accounts for about 6 percent of human-induced climate change.Beaulieu and colleagues measured nitrous oxide production rates in 72 streams. When summed across the globe,the results showed rivers and streams are the source of at least 10 percent of human-caused nitrous oxide emissionsto the atmosphere.“Changes in agricultural and land-use practices that result in less nitrogen being delivered to streams would reducenitrous oxide emissions from river networks,”Beaulieu said.1. From the second paragraph we can learn.A. actually rivers give off much more nitrous oxide than expectedB. scientists' calculation is totally wrongC. human activities release nitrous oxide in to the riversD. there is no nitrogen in fertilizer2.

Therewas no immediate comment from the firm but its website said it undertook projects that make “land from water byproviding large-scale floating constructions to create similar conditions as on land”.The Maldives began to work on an artificial island known as the Hulhumale near the crowded capital island ofMale in 1997 and more than 30,000 people have been settled there to ease congestion. The city, which has apopulation of 100,000, is already protected from rising sea levels by a 30-million-dollar sea wall, and thegovernment is considering increasingly imaginative ways to combat climate change.Nasheed, who staged the world's first underwater cabinet meeting in October to highlight his people's serious anddifficult situation, has even spoken of buying land elsewhere in the world to enable Maldivians to relocate if theirhomes are completed covered.He has also promised to turn his nation into a model for the rest of the world by becoming “carbon neutral”by2020. His plan involves ending fossil fuel use and powering all vehicles and buildings from “green”sources suchas burning coconut husks.1. Why do you think Mohamed Nasheed chose Dutch Docklands?A. Because it has experience in building floating structure.B. Because it has a good fame throughout the world.C. Because it charged much less than other companies.D. Because it supports building floating structures in the world.2.

For example, to absorb heat from the sun to heat water, you need large,flat, black surfaces. One way to do that is to build those surfaces specially, on the roofs of buildings. But why go toall that trouble when cities are full of black surfaces already, in the form of asphalt(柏油) roads?..Ten years ago, this thought came into the mind of Arian de Bondt, a Dutch engineer. He finally persuaded his bossto follow it up. The result is that their building is now heated in winter and cooled in summer by a system thatrelies on the surface of the road outside.The heat-collector is a system of connected water pipes. Most of them run from one side of the street to the other,just under the asphalt road. Some, however, dive deep into the ground.When the street surface gets hot in summer, water pumped through the pipes picks up this heat and takes it) into which underground through one of the diving pipes. At a depth of 100 metres lies a natural aquifer(蓄水层) have been built. The hot water from the street runs through these exchangers, 交换器several heat exchangers(warming the ground-water, before returning to the surface through another pipe. The aquifer is thus used as a heatstore.at exchangers to pick up the In winter, the working system is changed slightly. Water is pumped through the heheat stored during summer. This water goes into the building and is used to warm the place up. After performingthat task, it is pumped under the asphalt and its remaining heat keeps the road free of snow and ice.1. Which of the following is true according to the first two paragraphs?A. Arian de Bondt got his idea from his boss.B. Large, flat, black surfaces need to be built in cities.C. The Dutch engineer's system has been widely used.D. Heat can also be collected from asphalt roads.2. For what purpose are the diving pipes used?A. To absorb heat from the sun.B. To store heat for future use.C. To turn solar energy into heat energy.D. To carry heat down below the surface.3. From the last paragraph we can learn that.A. some pipes have to be re-arranged in winterB. the system can do more than warming up the buildingC. the exchangers will pick up heat from the street surfaceD. less heat may be collected in winter than in summer4. What is most likely to be discussed in the paragraph that follows?..A. What we shall do if the system goes wrong.B. What we shall do if there are no asphalt roads.C. How the system cools the building in summer.D. How the system collects heat in spring and autumn.8Use less energy. With a little effort, We already know the fastest, least expensive way to slow climate change:doing the Earth a favor and not much money, most of us could reduce our energy diets by 25 percent or more—while also helping our wallets.not to lose a little weight but to answer an annoying question —Not long ago, my wife, PJ, and I tried a new dietabout climate change.

英语科普类阅读文本解读及做题技巧
英语科普类阅读文本解读及做题技巧作者:符爱萍来源:《中学课程辅导·教师教育(上、下)》2020年第17期摘要:高中英语阅读教学是学生学习英语的重要方法,其中文本解读是重要组成部分。
通过文本解读的过程能对文章进行解读分析,能更好地了解作者写作意图、文章主题脉络、文本内容,学习文章语言知识及文化内涵。
因此,本文针对高考英语科普阅读理解文本的语篇和词汇特点,探究正确高效的阅读策略和解题技巧,以提升学生的阅读理解能力。
关键词:科普阅读;文本特征;解题技巧中图分类号:G633.41 文献标识码:A文章编号:1992-7711(2020)17-075-1科普类阅读理解是高考英语阅读理解中的重点与难点,阅读题材一般分为自然科學,人文科学和社会科学三大类。
从高中英语新课程标准的目标来看,考生通过科普类阅读,可以提高用英语获取信息处理信、分析问题和解决问题的能力,为未来发展和终生学习奠定良好的基础。
一、科普类阅读的文本风格科普类阅读文章从题材上讲可分为两类:一类说明文,文章往往运用描述、定义、分类、实验等方法探寻、分析、证实和讲解科学知识;另一类为议论文,大多围绕某一科学观点进行论述,论据充分,论证方法清晰。
1.语篇特征。
科普类文章通常学术专业性强,信息量大,结构严谨,段落之间的逻辑性不强,段落之间的内在联系并不十分密切,考生读文章时总感觉读懂了,但做题时却是雾里看花。
因此,学生要从每一段出发,在对每一段内容进行理解的前提下获得对整篇文章的准确把握。
2.语言特征。
一是词汇运用。
科普类阅读文章中词汇正式准确,单词的意思稳定单一,不带感情色彩,又会出现较为生僻的专业词汇,且具有特定的含义。
科普文的词汇就成了考生成功解题的拦路虎,阅读过程的心理障碍。
二是句式运用。
科普文中为了表达更多的信息,常使用长句,且结构复杂,往往从句交叉了较多倒装,虚拟省略等比较复杂的语言现象。
所以,即使文章句中没有生词,考生也未必能够完全理解文章内容,做题就会出现偏差。
(完整版)高考英语阅读理解科普类说明文4篇--较难(有答案)
高考英语说明文4篇1Here is an astonishing and significant fact: Mental work alone can’t makeus tire. It sounds absurd/əb'sɜːd/荒谬的. But a years ago, scientists tried to find out how long the human brain could labor without reaching a stage 阶段of fatigue /fə'tiːg/(疲劳). To the amazement of these scientists, they discovered that blood passing through the brain, when it is active, shows no fatigue at all! If we tooka drop of blood from a day laborer劳动者, we would find it fullof fatigue toxins /'tɒksɪn/ (毒素) and fatigue products. But if wetook blood from the brain of an Albert Einstein, it would show nofatigue toxins at the end of the day.So far as the brain is concerned, it can work as well and swiftly很快地at the end of eight or even twelve hours of effort as at the beginning. The brain istotally tireless. So what makes us tired?Some scientists declare that most of our fatigue comes from our mental and emotional(情绪的) attitudes. One of England’s most outstanding scientists, J.A. Hadfield, says, “The greater part of the fatigue from which we suffer is of mental origin /'ɒrɪdʒɪn/起源. In fact, fatigue of purely physical origin is rare.”Dr. Brill, a famous American scientist, goes even further. He declares, “One hundred percent of the fatigue of sitting worker in good health is due to emotional problems.”What kinds of emotions make sitting workers tired? Joy? Satisfaction?No! A feeling of being bored, anger, anxiety/æŋ'zaɪətɪ/焦虑, tenseness紧张, worry, a feeling of not being appreciated---those are the emotions that tire sitting workers. Hard work by itself seldom causes fatigue. We get tired because our emotions produce nervousness in the body.1. What surprised the scientists a few years ago?A. Fatigue toxins could hardly be found in a laborer’s blood.B. Albert Einstein didn’t feel worn after a day’s work.C. The brain could work for many hours without fatigue.D. A mental worker’s blood was filled with fatigue toxins.2. According to the author, which of the following can make sitting workers tired?A. Challenging mental work.B. Unpleasant emotions.C. Endless tasks.D. Physical labo3. What’s the author’s attitude towards the scientists’ idea?A. He agrees with them.B. He doubts them.C. He argues against them.D. He hesitates to accept them.4. We can infer from the passage that in order to stay energetic, sitting workers need to ________.A. have some good food.B. enjoy their workC. exercise regularlyD. discover fatigue toxins2They baby is just one day old and has not yet left hospital. She is quietbut alert /ə'lɜːt/(警觉). Twenty centimeters厘from her face researchershave placed a white card with two black spots on it. She stares at it carefully.A researcher removes the card and replaces it by another, this time with the spots differently spaced. As the cards change from one to the other, her gaze(凝视)starts to lose its focus — until a third, with three black spots,is presented. Her gaze returns: she looks at it for twice as long as she did at the previous card. Can she tell that the number two is different from three, just 24 hours after coming into the world?Or do newborns simply prefer more to fewer? The same experiment, but with three spots shown before two, shows the same return of interest when the number of spots changes. Perhaps it is just the newness 名,新奇? When slightly older babies were shown cards with pictures of objects (a comb, a key, an orange and so on), changing the number of objects had an effect separate from changing the objects themselves. Could it be the pattern that two things make, as opposed to three? No again. Babies paid more attention to squares moving randomly on a screen when their number changed from two to three,or three to two. The effect even crosses between senses. Babies who were repeatedly shown two spots became more excited when they then heard three drumbeats than when they heard just two; likewise (同样地)when the researchers started with drumbeats and moved to spots.5. The experiment described in Paragraph 1 is related to the baby’s__.A. sense of hearingB. sense of sightC. sense of touch D sense of smell6. Babies are sensitive to the change in______.A. the size of cardsB. the colour of picturesC. the shape of patternsD. the number of objects7. Why did the researchers test the babies with drumbeats?A. To reduce the difficulty of the experiment.B. To see howbabies recognize sounds.C. To carry their experiment further.D. To keep the babies’interest.8. Where does this text probably come from?A. Science fiction.B. Children’s literature.C. An advertisement.D.A science report3Last night’s meteor(流星) 英/'miːtɪə/ shower left many people in the community dissatisfied and demanding 苛求的;要求高的;吃力的answers. According to Gabe Rothsclild, Emerald Valley’s mayor市长, people gathered in thesuburbs /'sʌbɜːb/of the city, carrying heavy telescopes, expecting to watch the brightly burning meteors passing through the sky. What they found instead was a sky so brightene by the city’s lights that it darkened the light of the meteors passing overhead. “My family was so frustrated,” admitted town resident Duane Cosby, “We wanted to make this an unforgettable family outing, but it turned out to be a huge disappointments.”Astronomers- /ə'strɒnəmə/n. 天文学家--scientists who study stars and planets---- have beencomplaining about this problem for decades. They say that light pollution prevents them from seeing objects in the sky that they could see quite easily in the past. They call on people and the government to take measures to fightagainst it.There is yet a population besides professional and amateur /ˈæmətə(r)/美 /'æmə.tʃʊr/n. 爱好者star observers that suffers even more from light pollution. This population consists of birds, bats frogs, snakes, etc. For example, outdoor lighting severely affects migrating(迁徙的)birds. According to the International Dark-Sky Association. “100million birds a year throughout North America die in crashes 撞碎with lighted buildings and towers.”Countless more animals casualties(伤亡)result from the use of artificial lighting. Clearly, people enjoy the benefits of lighting their evenings, but some scientists think it can be harmful for humans, too. They worry that exposure to light while sleeping can increase pers on’s chances of getting cancer. Emerald Valley is only one community that is becoming aware of the negative effects of light pollution. For years, Flagstaff, Arizona/,æri'zəunə/美 /,æri'zəunə/n. 美国亚利桑那州, has enforced lighting regulations in its city in order to assist astronomers at the Lowell Observatory.英 /əb'zɜːvət(ə)rɪ/美 /əb'zɝvətɔri/n. 天文台;气象台;瞭望台Similar efforts have been made worldwide, and a movement isunderway 进行中的to remind us to turn off lights when we are not using them, so thatother creatures can share the night.9.It happened last night thatA. the city’s lights affected the meteor watchingB. the meteors flew past before being noticedC. the city light show attracted many peopleD. the meteor watching ended up a social outing10.

Saving wildlife is saving ourselvesB. Great efforts should be made to save energyC. Human activities should be environmentally friendlyD. New equipment should be introduced for space study4Almost every machine with moving parts has wheels, yet no one knows exactly when the first wheel was invented or what it was used for. We do know,however,that they existed over 5,500years ago in ancient Asia.The oldest known transport wheel was discovered in 2002 in Slovenia. It is over 5,100 years old. Evidence suggests thatwheels for transport didn't become popular for .while, though . This could be because animals did a perfectly good job of carryingfarming tools and humans around.But it could also be because of a difficult situation. While wheels need to roll on smooth surfaces, roads with smooth surfaces weren't going to be constructed until there was plenty of demand for them. Eventually, road surfaces did become smoother, but this difficult situation appeared again a few centuries later. There had been no important changes in wheel and vehicle design before the arrival of modern road design.In the mid-1700s,a Frenchman came up with a new design of road--a base layer (层)of large stones covered with a thin layer of smaller stones. A Scotsman苏格兰人improved on this design in the 1820s and a strong, lasting road surface became a reality. At around the same time, metal hubs英 /hʌb/美 /hʌb/n. 中心;毂;木片(the central part of a wheel)、came into being, followed by the Wheels were invented in 1967, sixty years after the appearance of tarmacked roads(泊油路).

因此科普知识类文章是每年的必考题。
分析历年的科普类文章我们不难发现以下特点:1.文章逻辑性强,条理清楚,语法结构简单,用语通俗。
2.文章内容注重科技领域的新发现。
内容新颖,从而使文章显得陌生,内容抽象复杂。
3.命题方面注意对具体细节的准确理解和以之为依据的推理判断。
4.以人们的日常行为或饮食健康入手,探讨利弊,诠释过程,阐述概念。
【应试对策】许多考生在考试时感到困惑的是:为什么一些没有超越中学语法和词汇范围的篇章,读起来却不能正确理解,或者要花费很多时间才能读懂呢?这种现象的产生与阅读方法有很大的关系。
例如,有的考生在考试时一见到文章就立刻开始读,结果读了半天,还不知道短文讲的是什么,试题要求了些什么,结果浪费了大量的时间,而阅读效果并不好。
那么,怎样读效果才好呢?任何一种阅读方法或技巧的使用,都是由篇章特点和试题本身的要求决定的,应根据不同的体裁和试题要求采取不同的策略。

(完整版)高考英语阅读理解科普类说明文4篇--较难(有答案)
高考英语说明文 4 篇1Here is an astonishing and significant fact: Mental work alone can ' m t akeus tire. It sounds absurd /?b's ??d/荒谬的. But a years ago, scientists tried to find out howlong the human brain could labor without reaching a stage 阶段of fatigue /f?'ti?g/(疲劳). To the amazement of these scientists, they discovered that blood passing through the brain, when it is active, shows no fatigue at all! If we tooka drop of blood from a day laborer 劳动者, we would find it full of fatigue toxins /'t?ks?n/ (毒素) and fatigue products. But if wetook blood from the brain of an Albert Einstein, it would show no fatigue toxins at the end of the day.So far as the brain is concerned, it can work as well and swiftly 很快地at the end of eight or even twelve hours of effort as at the beginning. The brain is totally tireless. So what makes us tired?Some scientists declare that most of our fatigue comes from our mental and emotional(情绪的) attitudes. One of England 'm s ost outstanding scientists, J.A. Hadfield, says, “ Th egreater part of the fatigue from which we suffer is of mental origin /'?r?d??n/起源. In fact, fatigue of purely physical origin is rare. D”r. Brill, a famous American scientist, goes even further. He declares, “ One hundred percent of the fatigue of sitting worker in good health is due to emotional problems. ”What kinds of emotions make sitting workers tired? Joy? Satisfaction? No! A feeling of being bored, anger, anxiety /??'za?? t?/焦虑, tenseness 紧张, worry, a feeling of not being appreciated---those are the emotions that tire sitting workers. Hard work by itself seldom causes fatigue. We get tired because our emotions produce nervousness in the body.1. What surprised the scientists a few years ago?A. Fatigue toxins could hardly be found in a laborer s 'blood.B. Albert Einstein didn ' fe t el worn after a day ' w s ork.C. The brain could work for many hours without fatigue.D. A mental worker ' b s lood was filled with fatigue toxins.2. According to the author, which of the following can make sitting workers tired?A. Challenging mental work.B. Unpleasant emotions.C. Endless tasks.D. Physical labo3. What' s the author ' at s titude towards the scientists idea'?A. He agrees with them.B. He doubts them.C. He argues against them.D. He hesitates to accept them.4. We can infer from the passage that in order to stay energetic, sitting workers need to.A. have some good food.B. enjoy their workC. exercise regularlyD. discover fatigue toxins2They baby is just one day old and has not yet left hospital. She is quiet but alert /?'l??t/ (警觉). Twenty centimeters 厘from her face researchers have placed a white card with two black spots on it. She stares at it carefully. A researcher removes the card and replaces it by another, this time with the spots differently spaced. As the cards change from one to the other, her gaze(凝视)starts to lose its focus —until a third, with three black spots, is presented. Her gaze returns: she looks at it for twice as long as she did at the previous card. Can she tell that the number two is different from three, just 24 hours after coming into the world?Or do newborns simply prefer more to fewer? The same experiment, but with three spots shown before two, shows the same return of interest when the number of spots changes. Perhaps it is just the newness 名,新奇? When slightly older babies were shown cards with pictures of objects (a comb, a key, an orange and so on), changing the number of objects had an effect separate from changing the objects themselves. Could it be the pattern that two things make, as opposed to three? No again. Babies paid more attention to squares moving randomly on a screen when their number changed from two to three, or three to two. The effect even crosses between senses. Babies who were repeatedly shown two spots became more excited when they then heard three drumbeats than when they heard just two; likewise (同样地)when the researchers started with drumbeats and moved to spots.5. The experiment described in Paragraph 1 is related to the baby ' s__.A. sense of hearingB. sense of sightC. sense of touch D sense of smell6. Babies are sensitive to the change in _____ .A. the size of cardsB. the colour of picturesC. the shape of patternsD. the number of objects7. Why did the researchers test the babies with drumbeats?A. To reduce the difficulty of the experiment.B. To see howbabies recognize sounds.C. To carry their experiment further.D. To keep the babies in'terest.8. Where does this text probably come from?A.

According to Gabe Rothsclild, Emerald Valley 'm s ayor 市长, people gathered in the suburbs /'s?b??b/of the city, carrying heavy telescopes, expecting to watch the brightly burning meteors passing through the sky. What they found instead was a sky so brightene by the city'lig s hts that it darkened the light of the meteors passing overhead.“ M yfamily was so frustrated, adm”itted town resident Duane Cosby, “ We wanted to make this an unforgettable family outing, but it turned out to be a huge disappointments. ”Astronomers- /?'str?n?m?/n. 天文学家--scientists who study stars and planets ------have beencomplaining about this problem for decades. They say that light pollution prevents them from seeing objects in the sky that they could see quite easily in the past. They call on people and the government to take measures to fight against it.There is yet a population besides professional and amateur /??m? t?(r)/美/'?m ?.t??r/n. 爱好者star observers that suffers even more from light pollution. This population consists of birds, bats frogs, snakes, etc. For example, outdoor lighting severely affects migrating(迁徙的)birds. According to the International Dark-Sky Association. “ 100million birds a year throughout North America die in crashes 撞碎with lighted buildings and towers. ”Countless more animals casualties(伤亡)result from the use of artificial lighting. Clearly, people enjoy the benefits of lighting their evenings, but some scientists think it can be harmful for humans, too. They worry that exposure to light while sleeping can increase person 's chances of getting cancer. Emerald Valley is only one community that is becoming aware of the negative effects of light pollution.

We do know ,however ,that they existed over 5,500years ago in ancient Asia.The oldest known transport wheel was discovered in 2002 in Slovenia. It is over 5 ,100 years old. Evidence suggests thatwheels for transport didn't become popular for .while, though . This could be because animals did a perfectly good job of carrying farming tools and humans around.But it could also be because of a difficult situation. While wheels need to roll on smooth surfaces, roads with smooth surfaces weren't going to be constructed until there was plenty of demand for them. Eventually, road surfaces did become smoother, but this difficult situation appeared again a few centuries later. There had been no important changes in wheel and vehicle design before the arrival of modern road design.In the mid-1700s,a Frenchman came up with a new design of road--a base layer (层)of large stones covered with a thin layer of smaller stones.

高考英语科普说明文的命题特点及阅读技巧分析
高考英语科普说明文的命题特点及阅读技巧分析摘要:近年来,在我国高考英语试卷中,科普说明文的出现概率大幅提升,已成为当前高考英语试卷中的重要构成部分之一。
而相较于其他试卷部分而言,英语科普说明文中具有独特选材、语言逻辑性强、词汇涉猎面广等诸多命题特点,也具有较高的解读难度系数,对师生皆造成了诸多困惑。
因此为完善这一问题,提高学生对高考英语科普说明文的阅读理解能力,本文对其主要的命题特点以及阅读技巧展开以下深入分析。
关键词:高考英语;科普说明文;命题特点;阅读技巧近年来随着新教改运动的开展,我国教育体系逐渐转变了教学理念与教学思维,将提高学生综合素养、语言理解能力与思维宽度为主要教学目的。
因此在当前高考英语试卷中,逐渐提高了科普说明文的出现概率与所占分值。
例如在我国2018年全国卷1中,便选用了一篇讲述新旧电气设备差别、旧电气设备缺乏节能环保性的科普说明文。
而本文也对当前我国各高考科普说明文中主要的命题特点与阅读技巧展开分析。
一、主要命题特点分析(一)高考英语科普说明文选材独特的命题特点首先,其他高考英语阅读题型的选材方向普遍为日常生活、国内时事或是人物传记,与学生的日常学习生活息息相关的选材内容。
但是高考英语科普说明文虽然也会涉猎一些国内政治与社会时事,但是主要的选材方向仍旧源于科技层面,这也与学生的实际学习生活缺乏衔接性与关联性。
例如上述提及的我国2018全国卷1中选用的科普说明文,便主要讲述新旧电气设备的区别,此外也涉猎到近年来世界范围内具有较高程度社会关注度的环境保护与节能问题。
其次,当前我国绝大部分高考英语科普说明文的选材来源主要为英美等以英语为母语的国家,相对来说科普说明文具有更高的语言逻辑能力与表达灵活性。
(二)高考英语科普说明文结构紧凑的命题特点首先,在文章段落层面上而言,我国高考英语科普说明文主要为四部分构成,分别为文章的开头标题、导句、文章主体结构以及结论。
其中,标题为阐述整体科普说明文的主要科技科普方向,导语与摘要同理,高度总结文章的主要科普方向、所提问题,而文章主体结构为对标题与导语中所提及具体问题的详细讲述,最后文章结论则是将所讲述问题与相应科学理论的总结与重复阐述。

2014年高考英语二轮复习阅读理解拉分题(较难题目)特训:节能环保类1The Goldman Environmental Foundation recently recognized a group of individuals (个体) for their efforts to protect the environment. Each year, the American-based group honors environmental activists from six different areas.The first three winners of the 2012 Goldman Prize are from Kenya, the Philippines and China.The Goldman Environmental Foundation says Ikal Angelei is a hero to those who live around Lake Turkana. The Kenyan woman received the award because of her efforts to stop a dam project on a river in Ethiopia. Critics say the dam will harm the lake and restrict (限制) the flow of water for people who live nearby.The Philippine island of Mindoro is home to those who depend on the area’s natural resources for food and jobs. Edwin Gariguez became concerned when a European company announced plans to mine for nickel (镍) on the island. The Roman Catholic minister said waste materials from the mining project would pollute the water and destroy the forests. So he started a campaign to stop the project.In China, Ma June is working with businesses to clean up their pollution. He formed a group that collects information about pollution, and publishes it on the Internet.The Goldman Prize was also awarded to activists from Argentina, Russia and the United States.Sofia Gatica of Argentina is from a town where farmers commonly use pesticide (杀虫剂) products to protect soybean crops from insects. The town also has a high rate of cancer. Sofia Gatica belie ved that pesticide use was responsible for the death of her baby. She worked with other mothers to get government officials to ban the use of chemicals near populated areas.Evgenia Chirikova objects to the plans to build a road through a protected forest just outside Moscow. She has demanded that Russian officials redirect th e road away from the forest. She and her followers have been arrested for their activities. However, their campaign has gained widespread public support.The sixth winner is American Caroline Cannon—a community leader in Point Hope, Alaska. Miz Cannon is fighting to keep Arctic waters safe from oil and gas exp loration.60. We can know from the passage that ______.A. the dam project has been preventedB. the first three activists are all from AsiaC. a European company is going to dig for nickelD. Ma June is trying to stop oil and gas exploration61. From the 7th paragraph, we can know that ______.A. pesticide use accounts for a high-rate of cancerB. Sofia managed to ban the use of chemicalsC. the farmers mainly live on unpolluted productsD. the death of the baby was due to delayed treatment62. What do we know about Evgenia Chirikova?A. She plans to build a road to protect the forest.B. She is in charge of a project far away from the road.C. She persuaded the government to set her followers free.D. Her environmental action has been widely acknowledged.63. What would be the best title for the passage?A. Six Advanced Individuals for Hard WorkB. Efforts to Create a Clean and Beautiful WorldC. Six Environmental Activists Win Goldman PrizeD. The Goldman Environmental Foundation Prize2SCS Global Services (SCS) has evaluated a new methodology for measuring the carbon sequestration(封存) ability of soil under the Verified(验证) Carbon Standard (VCS), a leading greenhouse gas (GHG) accounting system. The methodology, developed by The Earth Partners, will allow land managers who sequester GHGs in grasslands and farmlands to produce carbon credits for sale in the voluntary market.Managers of grasslands and farmlands can increase carbon sequestration in soil by practices such as changing grazing(放牧) practices and operating treatments designed to improve the variety and productivity of plant groups. The Earth Partners is presently piloting this methodology with farmers across seven million acres of the Palouse River and Columbia Plateau regions in the Pacific Northwest.“The VCS p rogram has achieved an important milestone in now combining grassland and rangeland carbon offset(抵消,补偿) projects," said Dr. Robert J. Hrubes, Executive Vice President of SCS."SCS looks forward to approving and verifying agricultural carbon offset projects that use thisvery powerful new methodology."The VM0021 Soil Carbon Quantification Methodology is based on decades of soil carbon research and testing conducted by top soil scientists. The methodology was developed by The Earth Partners and verified by Environmental Services, Inc. as well as SCS Global Services. It is the first soil carbon methodology to be approved for use under the VCS."This widely tested methodology is the first to specially deal with soils in a market," said Steven I. Apfelbaum, Chairman of Applied Ecological Services, Inc. and Director of Science with The Earth Partners. According to Apfelbaum, soils represent the second largest living sink of carbon on the planet.68. The new methodology is assessed according to .A. The Earth PartnersB. the Verified Carbon StandardC. Environmental Services, Inc.D. Applied Ecological Services, Inc.69. Carbon sequestration in soil can be strengthened by .A. selling carbon credits in the voluntary marketB. changing grazing practices and operating treatmentsC. reducing the variety and productivity of plant groupsD. decreasing farmlands in the Pacific Northwest70. Which of the following is true according to the passage?A. The VCS program proves to be successful in carbon offset projects.B. Many soil Carbon Methodologies have already been approved for use.C. The new methodology has been tested in many fields including soil.D. Soils seem to be the largest living sink of carbon on the planet.71. What is the attitude of SCS towards the new methodology?A. Opposed.B. Cautious.C. Doubtful.D. Approving.3Rainforest is home to around two-thirds of all plant and animal species found on land—in addition to millions of people who depend on them for survival—our remaining ancient forests are some of the most diverse ecosystems known to science. They are also vitally important to the health of our planet, especially when it comes to regulating the climate. But ancient forests around the world are under attack.Protecting rainforests is on the global agenda (议事日程) in a big way.Governments now recognize the importance of protecting tropical forests in order to avoid dangerous climate change, and there is now much debate. As governments try to thrash out the details of a new international agreement, expected to be signed at the end of 2009, they are discussing how best to include measures to save rainforests, and therefore address one of the major causes of climate change. Worldwide, forest destruction causes more greenhouse gas emissions (排放) each year than do all the trains, planes and cars on the planet. So if we are to deal with global warming, there is an urgent need to find ways to reduce the 20% of global greenhouse gas emissions caused by forest destruction each year, and to keep the remaining forests standing.We need to protect the planet’s remaining fores ts not only to stop climate change from getting worse, but to ensure that we can stand the impacts of global warming. Healthy forests absorb and store quantities of carbon, helping to regulate temperature and generate rain. When they are destroyed, this carbon is released into the atmosphere. Thus keeping forests standing is both a critical part of regulating climate change and of adapting to a warmer world.To date, most of the talk has focused on how to pay for reducing deforestation (滥伐森林), rather than on how to actually go about doing it. We believe governments need to support local people to protect theirenvironment, as we have been showing for 20 years can be a very effective way of saving rainforests.1. The best title for the passage is .A. Rainforest and Climate ChangeB. Strategies on Protecting RainforestC. Serious Deforestation to RainforestD. Present Situation of Rainforest2. From the first paragraph we can infer that .A. we have little rainforest left until nowB. the ancient forests are being destroyedC. rainforest control the planet in many waysD. Rainforest is home to all plants and animals on earth3. The underlined part “thrash out” in the second paragraph means.A. try to understandB. come up withC. hide awayD. have a thorough discussion4. Greenhouse gas emissions caused by forest destruction .A. are the same amount by transport on earthB. take 20% of global greenhouse gas emissionsC. can be avoided by setting measures onlyD. have nothing to do with climate change5. From the text we can learn that healthy forest .A. can keep us healthy and happyB. can increase the effect from global warmingC. can be helpful in adjusting the temperatureD. can give out large amounts of carbon4Rivers may be a significant source of the greenhouse gas nitrous oxide (一氧化二氮), scientists now find.Their calculation suggests that across the globe the waterways contribute three times the amount of nitrous oxide to the atmosphere as had been estimated by the International Panel on Climate Change (IPCC), the United Nations scientific body charged with reviewing climate change research. They found that the amount of nitrous oxide produced in streams is relatedto human activities that release nitrogen (氮) into the environment, such as fertilizer use and sewage discharges.“Human activities, including fossil fuel combustion and intensive agriculture, have increased the availability of nitrogen in the environment,” said Jake Beaulieu of the University of Notre Dame and the U.S. Environmental Protection Agency in Cincinnati, Ohio, and lead author of the paper published this week in the journal Proceedings of the National Academy of Sciences.“Much of this nitrogen is transported into river and stream networks,” Beaulieu said. There, microbes (微生物) convert the nitrogen into nitrous oxide (also called laughing gas) and an inert gas called dinitrogen (二氮).The finding is important, the researchers say, because nitrous oxide is a powerful greenhouse gas that contributes to climate change and destruction of the stratosphere’s ozone layer, which protects us from the sun’s harmful ultraviolet (紫外线) radiation. Compared with carbon dioxide, nitrous oxide is 300-fold more powerful in terms of its warming potential, though carbon dioxide is a far more common greenhouse gas. Scientists estimate nitrous oxide accounts for about 6 percent of human-induced climate change.Beaulieu and colleagues measured nitrous oxide production rates in 72streams. When summed across the globe, the results showed rivers and streams are the source of at least 10 percent of human-caused nitrous oxide emissions to the atmosphere.“Changes in agricultural and land-use practices that result in less nitrogen being delivered to streams would reduce nitrous oxide emissions from river networks,” Beaulieu said.1.

President Mohamed Nasheed has vowed a fight for survival, and last monthhe signed a deal with a Dutch company to study proposals for a floating structure that could support a conference centre, homes and an 18-hole golf course.“It is still early stages and we are awaiting a report on the practicality,” a government official who declined to be named said. The company, Dutch Docklands, is currently building floating developments in the Netherlands and Dubai. There was no immediate comment from the firm but its website said it undertook projects that make “land from water by providing large-scale floating constructions to create similar conditions as on land”.The Maldives began to work on an artificial island known as the Hulhumale near the crowded capital island of Male in 1997 and more than 30,000 people have been settled there to ease congestion. The city, which has a population of 100,000, is already protected from rising sea levels by a30-million-dollar sea wall, and the government is considering increasingly imaginative ways to combat climate change.Nasheed, who staged the world’s first underwater cabinet meeting in October to highlight his people’s serious and difficult situation, has even spoken of buying land elsewhere in the world to enable Maldivians to relocate if their homes are completed covered.He has also promised to turn his nation into a model for the rest of the world by becoming “carbon neutral” by 2020. His plan involves ending fossil fuel use and powering all vehicles and buildings from “green” sources such as burning coconut husks.1. Why do you think Mohamed Nasheed chose Dutch Docklands?A. Because it has experience in building floating structure.B. Because it has a good fame throughout the world.C. Because it charged much less than other companies.D. Because it supports building floating structures in the world.2. The Hulhumale was built with the purpose of .A. attracting more visitorsB. making it a new capitalC. making the capital less crowdedD. fighting against climate change3. According to the last two paragraphs, Nasheed is a person who .A. has succeeded in buying land abroadB. is more than well-knownC. has thought more for his nationD. has stopped using fossil fuel4. The underlined word “vowed” in paragraph 3 can be replaced by.A. endedB. promisedC. failedD. weighed6PLAYA GRANDE, COSTA RICA? This resort town was long known for Leatherback Sea Turtle (棱皮龟) national Park, nightly turtle beach tours and even a sea turtle museum. However, on a beach where dozens of turtles used to nest on a given night, scientists spied only 32 leatherbacks all of last year. With leatherbacks threatened with extinction (灭绝), Playa Grande’s turtle museum was abandoned three years ago and now sits among a sea of weeds. And the beachside ticket office for turtle tours was washed away by a high tide in September. “We do not promote that as a turtle tourism destination any more because we realize there are far too few turtles to please,” said Alvaro Fonseca, a park ranger (管理员).Even before scientists found temperatures going up over the past decade, sea turtles were threatened by beach development, drift net fishing and Costa Ricans interest in eating turtle eggs. But climate change may cause the most serious harm to an animal that has lived in the Pacific for 150million years.Sea turtles are sensitive to numerous effects of warming. They feed on reefs, which are dying in hotter seas. They lay eggs on beaches that are being covered by rising seas and more violent waves.More uniquely their gender (性别) is determined, not by genes but by the egg’s temperature during development. Small rises in beach temperatures can result in ail-female populations, obviously problematic for survival. If the sand around the eggs hits 30 degrees Celsius, the gender balance shits to females: at about 32 degrees they are all female. Above 34, you get boiled eggs.On some nesting beaches, scientists are artificially cooling nests with shade or irrigation and trying to protect broader areas of coastal property from development to ensure that turtles have a place to nest as the seas rise.5. Why does the resort town stop promoting it’s turtle tourism?A. It decides not to disturb the turtles’ normal life.B. Tourists have lost interest in watching turtles.C. There are only very few turtles now.D. The turtle museum was destroyed by a high tide.6. Which of the following is the major factor in the turtles endangerment?A. The locals eating habit.B. Drift net fishing.C. Beach development.D. Global warming.7. We learn from the last paragraph that scientists .A. are doing research on the sea riseB. are moving turtles to new homesC. are protecting turtles’ nestsD. are getting rid of sea weeds8. The passage intends to .A. introduce a special kind of sea turtleB. explain the mystery of turtles’ eggsC. show the dangers a certain kind of turtle is facingD. attract more visitors to a sea turtle museum7Sometimes, the simplest ideas are the best. For example, to absorb heat from the sun to heat water, you need large, flat, black surfaces. One way to do that is to build those surfaces specially, on the roofs of buildings. But why go to all that trouble when cities are full of black surfaces already, in the form of asphalt(柏油) roads?Ten years ago, this thought came into the mind of Arian de Bondt, a Dutch engineer. He finally persuaded his boss to follow it up. The result is that their building is now heated in winter and cooled in summer by a system that relies on the surface of the road outside.The heat-collector is a system of connected water pipes. Most of them run from one side of the street to the other, just under the asphalt road. Some, however, dive deep into the ground.When the street surface gets hot in summer, water pumped through the pipes picks up this heat and takes it underground through one of the diving pipes. At a depth of 100 metres lies a natural aquifer(蓄水层) into which several heat exchangers(交换器) have been built. The hot water from the street runs through these exchangers, warming the ground-water, before returning to the surface through another pipe. The aquifer is thus used as a heat store. In winter, the working system is changed slightly. Water is pumped through the he at exchangers to pick up the heat stored during summer. This water goes into the building and is used to warm the place up. After performingthat task, it is pumped under the asphalt and its remaining heat keeps the road free of snow and ice.1. Which of the following is true according to the first two paragraphs?A. Arian de Bondt got his idea from his boss.B. Large, flat, black surfaces need to be built in cities.C. The D utch engineer’s system has been widely used.D. Heat can also be collected from asphalt roads.2. For what purpose are the diving pipes used?A. To absorb heat from the sun.B.

From the last paragraph we can learn that .A. some pipes have to be re-arranged in winterB. the system can do more than warming up the buildingC. the exchangers will pick up heat from the street surfaceD. less heat may be collected in winter than in summer4. What is most likely to be discussed in the paragraph that follows?A. What we shall do if the system goes wrong.B. What we shall do if there are no asphalt roads.C. How the system cools the building in summer.D. How the system collects heat in spring and autumn.8We already know the fastest, least expensive way to slow climate change: Use less energy. With a little effort, and not much money, most of us could reduce our energy diets by 25 percent or more—doing the Earth a favor while also helping our wallets.Not long ago, my wife, PJ, and I tried a new diet—not to lose a little weight but to answer an annoying question about climate change. Scientists have reported recently that the world is heating up even faster than predicted only a few years ago, and that the consequences could be severe if we don’t keep reducing emissions(排放) of carbon dioxide(CO) and other2 greenhouse gases that are trapping heat in our atmosphere.We decided to try an experiment. For one month we recorded our personalemissions of CO. We wanted to see how much we could cut back, so we went2on a strict die t. The average US household(家庭) produces about 150 poundsa day by doing common-place things like turning on air-conditioning of CO2or driving cars. That’s more than twice the European average and almost five times the global average, mostly because Americans drive more and have bigger houses. But how much should we try to reduce?For an answer, I checked with Tim Flannery, author of The Weather Makers: How Man Is Changing the Climate and What It Means for Life on Earth. In his book, he had challenged readers to make deep cuts in personal emissions to keep the world from reaching extremely important tipping points, such as the melting(融化) of the ice sheets in Greenland or West Antarctica.emissions by 80 percent, “To stay below that point, we need to reduce CO2“ he said.Good advice, I thought. I’d opened our bedroom windows to let in the wind. We’d gotten so used to keeping our air-conditioning going around the clock. I’d almost forgotten the windows even opened. We should not let this happen again. It’s tim e for us to change our habits if necessary.1. Why did the author and his wife try a new diet?A. To take special kinds of food.B. To respond to climate change.C. To lose weight.D. To improve their health.2. The underlined words “tipping points” most probably refer to “”.A. freezing pointsB. burning pointsC. melting pointsD. boiling points3. It can be inferred from the passage that .A. it is necessary to keep the air-conditioning on all the timeB. it seems possible for every household to cut emissions of CO2a month C. the average US household produces about 3, 000 pounds of CO2D. the average European household produces about 1, 000 pounds of COa month24. Which of the following would be the best title for this passage?A. Saving Energy Starts at HomeB. Changing Our Habits Begins at WorkC. Changing Climate Sounds ReasonableProves DifficultD. Reducing Emissions of CO29The need to feed a growing population is putting much pressure on the world’s supply of water. With 97% of the world’s w ater too salty to be drunk or used in agriculture, the worldwide supply of water needs careful management, especially in agriculture. Although the idea of a water shortage (短缺) seems strange to someone fortunate enough to live in a high rainfall country, many of the world’s agricultural industries experience constant water shortages.Although dams can be built to store water for agricultural use in dry areas and dry seasons, the costs of water redistribution (重新分配) are very high. Not only is there the cost of the engineering itself, but there is also an environmental cost to be considered. Where valleys (山谷) are flooded to create dams, houses are lost and wildlife homes destroyed. Besides, water may flow easily through pipes to fields, but it cannot be transported from one side of the world to the other. Each country must therefore rely on the management of its own water to supply its farming requirements. This is particularly troubling for countries with agricultural industries in areas dependent on irrigation (灌溉). In Texas, farmers’ overuse of irrgation water has resulted in a 25% reduction of the water stores. In the Central Valley area of southwestern USA, a huge water engineering project provided water for farming in dry valleys, but much of the wateruse has been poorly managed.Saudi Arabia’s attempts to grow wheat in desert areas have seen the pumping o f huge quantities of irrigation water from underground reserves. Because there is no rainfall in these areas, such reserves can only decrease, and it is believed that fifty years of pumping will see them run dry.1. From the first two paragraphs we learn that .A. much of the world’s water is available for useB. people in high rainfall countries feel luckyC. the costs of water redistribution should be consideredD. water can be easily carried through pipes across the world2. Which of the following is true?A. The water stores in Texas have been reduced by 75%.B. Most industries in the world suffer from water shortages.C. The underground water in Saudi Arabia might run out in 50 years.D. Good management of water use resulted from the project in the Central Valley.3. What is most likely to be discussed in the paragraph that follows?A. Steps to improving water use management.B. Ways to reduce the costs of building dams.C. Measures to deal with worldwide water shortages.D. Approaches to handling the pressure on water supply.4. The text is mainly about .A. water supply and increasing populationB. water use management and agricultureC. water redistribution and wildlife protectionD. water shortages and environmental protection10Businesses are witnessing a difficult time, which has in turn produced influence on consumers’ desire to go green. However, shoppers are still laying stress on environmental concerns.Two thirds of customers say that environmental considerations inform their purchases to the same degree as they did a year ago, while more than a quarter say that they are now even better aware of the environmental effect on what they buy.This may help to influence how shops store goods on their shelves. And the companies should still make efforts to become more environmentally friendly. Two out of three people think it is important to buy from environmentally responsible companies, with about one in seven saying that they had even decided to take their custom e lsewhere if they felt a company’s environmental reputation was not good enough.Harry Morrison, chief executive (主管) of the Carbon Trust, sympathizes: “I understand this situation where survival is very important now. But f rom environmental considerations, the clock is ticking—we don’t have much time. In addition, cutting carbon has an immediate effect as costs drop and a medium-term benefit for the brand.”Larger companies have an extra motivation to look at reducing their carbon footprint, as new rules next year will require businesses to buy carbon allowances to make up for their emissions (排放). Those that have taken early action will have a head start. More than two thirds of consumers are not clear about which companies are environmentally responsible. This suggests that firms that are able to relay clearly their message to the public will be in a pole position to attract shoppers.The Carbon Trust believes that it can help by informing customers about the good work companies are doing. “When companies are granted (授予) the standard, they can use a logo (标识) in all their marketing which makes。
