NOT GIVEN题型技巧分析判断题：顺序题型，注意定位词和考点词，注意区分FALSE和NOT GIVEN 的辨析，FALSE是文章有提到信息并且与题目信息对立，NOT GIVEN是文章没提及题目所问信息，所以考点词的推测对区分FALSE和NOT GIVEN 有很大影响。

Reading Passage 1 ECOTOURISM IN RUR A L MEXICO It’s not hard to advocate ecotourism——loosely defined as a form of travel that protects an area of the natural world while enabling the local people to preserve their culture and meet their daily needs.The hard part is making it work. Mexico，with many natural，still largely unspoiled areas and a land system based on community ownership，seems a likely ecotourism paradise.But its record of tourism development tells a different story. Now，thanks to the efforts of two consultants in Mexico City，the country may have figured out a way to benefit from the ecotourism market that is growing rapidly worldwide.Juan Carlos Ibarra and Antonio Suarez，co-owners of Balam Consultants，have succeeded where many other people have failed，helping local communities develop the ability to operate ecotourism ventures. Ibarra and Suarez began their current line of work in the early 1990s，helping the residents of the community of San Nicolas，outside Mexico City，develop and market recreational facilities that would attract tourists. Ibarra and Suarez spent more than 600 hours teaching people in the community business，marketing，and public relations skills.The result of this project was the San Nicolas Park，which now offers facilities for hiking and mountain biking on 2,304 hectares of land that otherwise would have been lost to illegal logging and urban sprawl.The project’s success is well regarded by professionals from around the world and is the most-visited ecotourism site in Mexico. The product of their efforts “shows what can be done.Its main value is that it enables those who will benefit or suffer most from ecotourism to take the decisions.” says Ron Mader of the website Americas Ecotourism.“The wonder of the work done by Ibarra and Suarez，”Mader says，“is that they make it look very simple.” An advantage for Mexico in the field of ecotourism development is land reforms implemented after the end of the Mexican Revolution in 1917.Property previously owned by the wealthy elite was redistributed to peasant communities in the form of communally owned village lands known as comunidades. Today，more than 23,000 communal groups Own and 1ive on 75 percent of Mexico’s land.Most of the country s splendid snowcapped volcanoes，lush jungles and white sand beaches are also communal property.This means that when tourists come to visit the country’s natural attractions，the local property owners should benefit. But some heavily promoted resorts，such as Cancun and Bahias de Huatulco，have been built On village lands that were taken by the government and sold to corporations. Although some local people are hired to work at these resorts，many do not have the appropriate skills or the knowledge of how these corporations work，said Ibarra. As a result，most of the well-paying jobs are filled by people from urban areas who have a better understanding of business Ibarra and Suarez are trying to stop this trend by working with the comunidades to develop community-based ecotourism projects.The two consultants have been conducting workshops on the subject in communities across the country. “In recent years，as the ecotourism boom reached Mexico，many companies started promoting trips to the wilderness areas of the country,” said Ibarra.“In the beginning，the owners of the lands in which ecotourism was being developed were not involved at all.Now，slowly but surely，rural populations have begun to perceive ecotourism as an economic alternative.” Commercially speaking，however，the residents of rural communities usually have no experience in running and marketing a business.Even if they have developed a well run project，visitors won’t come unless there is also effective marketing.After all，it is a business and they need to bring in customers. Ibarra and Suarez say teaching people in local communities how to run an ecotourism operation is easy.The hard part is helping rural inhabitants overcome a culturally ingrained notion that they are stupid and incapable of running such a business themselves. For every hour devoted to the instruction of business skills，the consultants spend four hours helping local residents build self-esteem and confidence.They are convinced that a project’s success depends on the involvement of the local landowners. Ron Mader views Ibarra and Suarez as pioneers in building successful ecotourism in Mexico.Their work.hesays，is“outstanding——not only because they have assisted in development of hiking and biking trails，but because they have demonstrated a profound respect for the communities Questions 1——5 Complete the summary below.Choose ONE ORTWO WORDS from the passage for each answer.Write your answers in boxes 1—5 on your answer sheet.

Most of Mexico’s beaches and jungles are communally owned. 7. The Mexican government has profited from the development of tourist resorts. 8. The number of local people working in tourism is decreasing. 9. Ibarra and Suarez want to encourage people who already understand business methods to work on ecotourism projects. 10. Recently，companies have been offering trips to see wild animals in Mexico. 11. People in the Mexican countryside often lack confidence in their own business skills. 12. The first thing that the consultants do in a community is to explain the benefits of ecotourism. 13 Ibarra and Suarez focus mainly on business skills training. 14 Ron Mader admires the attitude of Ibarra and Suarez to the rural 1andowners of Mexico. Reading Passage 2 High-tech Refrigeration 1 Refrigerators are the epitome of clunky technology: solid, reliable and just a little bit dull. They have not changed much over the past century, but then they have not needed to. They are based on a robust and effective idea--draw heat from the thing you want to cool by evaporating a liquid next to it, and then dump that heat by pumping the vapour elsewhere and condensing it. This method of pumping heat from one place to another served mankind well when refrigerators' main jobs were preserving food and, as air conditioners, cooling buildings. Today's high-tech world, however, demands high-tech refrigeration. Heat pumps are no longer up to the job. The search is on for something to replace them. 2 One set of candidates are known as paraelectric materials. These act like batteries when they undergo a temperature change: attach electrodes to them and they generate a current. This effect is used in infra-red cameras. An array of tiny pieces of paraelectric material can sense the heat radiated by, for example, a person, and the pattern of the array's electrical outputs can then be used to construct an image. But until recently no one had bothered much with the inverse of this process. That inverse exists, however. Apply an appropriate current to a paraelectric material and it will cool down. 3 Someone who is looking at this inverse effect is Alex Mischenko, of Cambridge University. Using commercially available paraelectric film, he and his colleagues have generated temperature drops five times bigger than any previously recorded. That may be enough to change the phenomenon from a laboratory curiosity to something with commercial applications. 4 As to what those applications might be, Dr Mischenko is still a little hazy. He has, nevertheless, set up a company to pursue them. He foresees putting his discovery to use in more efficient domestic fridges and air conditioners. The real money, though, may be in cooling computers. 5 Gadgets containing microprocessors have been getting hotter for a long time. One consequence of Moore's Law,which describes the doubling of the number of transistors on a chip every 18 months, is that the amount of heat produced doubles as well. In fact, it more than doubles, because besides increasing in number, the components are getting faster. Heat is released every time a logical operation is performed inside a microprocessor, so the faster the processor is, the more heat it generates. Doubling the frequency quadruples the heat output. And the frequency has doubled a lot. The first Pentium chips sold by Dr Moore's company, Intel, in 1993, ran at 60m cycles a second. The Pentium 4--the last "single-core" desktop processor--clocked up 3.2 billion cycles a second. 6 Disposing of this heat is a big obstruction to further miniaturisation and higher speeds. The innards of a desktop computer commonly hit 80℃. At 85℃, they stop working. Tweaking the processor's heat sinks (copper or aluminium boxes designed to radiate heat away) has reached its limit. So has tweaking the fans that circulate air over those heat sinks. And the idea of shifting from single-core processors to systems that divided processing power between first two, and then four, subunits, in order to spread the thermal load, also seems to have the end of the road in sight. 7 One way out of this may be a second curious physical phenomenon, the thermoelectric effect. Like paraelectric materials, this generates electricity from a heat source and produces cooling from an electrical source. Unlike paraelectrics, a significant body of researchers is already working on it. 8 The trick to a good thermoelectric material is a crystal structure in which electrons can flow freely, but the path of phonons--heat-carrying vibrations that are larger than electrons--is constantly interrupted. In practice, this trick is hard to pull off, and thermoelectric materials are thus less efficient than paraelectric ones (or, at least, than those examined by Dr Mischenko).

It prevents blood clotting.答案：C2. What does the author suggest about the future of the species discussed?A. It will become extinct.B. It will adapt to the changing environment.C. It will migrate to a new habitat.答案：B三、写作部分1. Task 1: The chart below shows the percentage of people in different age groups who used the internet in a European country in 2014.Summarize the information by selecting and reporting the main features, and make comparisons where relevant.答案：The chart illustrates the internet usage among different age groups in a European country in 2014. It is evident that the highest percentage of internet users was among the 25-34 age group, accounting for 92%. In contrast, the lowest usage was observed in the 65-74 age group, with only 46% of individuals accessing the internet. The 15-24 and 35-44 age groups had similar internet usage rates, both around 80%.2. Task 2: Some people believe that the increasing use of computers and mobile phones for communication has had a negative impact on young people's reading and writing skills. To what extent do you agree or disagree with this opinion? Give reasons for your answer and include any relevant examples from your own knowledge or experience.答案：I agree that the increasing reliance on technology forcommunication has had a detrimental effect on young people's reading and writing skills. Firstly, the instant nature of electronic communication encourages brevity and informality, which can lead to a decline in the use of proper grammar and punctuation. Secondly, the ease of editing and spell-checking tools may reduce the motivation to learn these skills thoroughly. However, it is also important to acknowledge that technology has made information more accessible and has the potential to enhance learning through interactive platforms. Overall, while technology has its benefits, it is crucial to ensure that young people continue to develop strong reading and writing skills alongside their digital literacy.四、口语部分1. Describe a book you have read recently.答案：I recently read "To Kill a Mockingbird" by Harper Lee. The book is set in the 1930s in a small Southern town and follows the story of Scout Finch, her brother Jem, and their father Atticus Finch, who is a lawyer. The story deals with themes of racial injustice and moral growth, and it's a powerful exploration of human nature. I found the characters to be well-developed and the plot engaging, making it a thought-provoking and enjoyable read.2. What do you think are the benefits of learning a foreign language?答案：Learning a foreign language has numerous benefits. Firstly,it enhances cognitive abilities, such as memory and problem-solving skills. Secondly, it broadens cultural understanding and fosters global awareness. Additionally, it can improve job prospects and provide opportunities for travel and international connections. Lastly, learning a new language is a rewarding challenge that can boost self-confidence and personal growth.。

Don’t wash those fossils！Standard museum practice can wash away DNA.1. Washing， brushing and varnishing fossils — all standard conservation treatments used by many fossil hunters and museum curators alike — vastly reduces the chances of recovering ancient DNA.2. Instead， excavators should be handling at least some of their bounty with gloves， and freezing samples as they are found， dirt and all， concludes a paper in the Proceedings of the National Academy of Sciences today.3. Although many palaeontologists know anecdotally that this is the best way to up the odds of extracting good DNA，Eva-Maria Geigl of the Jacques Monod Institute in Paris，France， and her colleagues have now shown just how important conservation practices can be. This information， they say，needs to be hammered home among the people who are actually out in the field digging up bones.4. Geigl and her colleagues looked at 3，200-year-old fossil bones belonging to a single individual of an extinct cattle species， called an aurochs. The fossils were dug up at a site in France at two different times — either in 1947， and stored in a museum collection， or in 2004， and conserved in sterile conditions at -20 oC.5. The team’s attempts to extract DNA from the 1947 bones all failed. The newly excavated fossils， however， all yielded DNA.6. Because the bones had been buried for the same amount of time， and in the same conditions， the conservation method had to be to blame says Geigl. “As much DNA was degraded in these 57 years as in the 3，200 years before，” she says.Wash in，wash out7. Because many palaeontologists base their work on the shape of fossils alone， their methods of conservation are not designed to preserve DNA， Geigl explains.8. The biggest problem is how they are cleaned. Fossils are often washed together on-site in a large bath， which can allow water — and contaminants in the form of contemporary DNA —to permeate into the porous bones. “Not only is the authentic DNA getting washed out， but contamination is getting washed in，” says Geigl.9. Most ancient DNA specialists know this already， says Hendrik Poinar， an evolutionary geneticist at McMaster University in Ontario， Canada. But that doesn’t mean that best practice has become widespread among those who actually find the fossils.10. Getting hold of fossils that have been preserved with their DNA in mind relies on close relationships betweenlab-based geneticists and the excavators， says palaeogeneticist Svante P bo of the Max Planck Institute for Evolutionary Anthropology in Leipzig， Germany. And that only occurs in exceptional cases， he says.11. P bo’s team， which has been sequencing Neanderthal DNA， continually faces these problems. “When you want to study ancient human and Neanderthal remains， there’s a big issue of contamination with contemporary human DNA，” hesays.12. This doesn’t mean that all museum specimens are fatally flawed， notes P bo. The Neanderthal fossils that were recently sequenced in his own lab， for example， had been part of a museum collection treated in the traditional way. But P bo is keen to see samples of fossils from every major find preserved in line with Geigl’s recommendations — just in case.在我们看来，阅读的满分并不是遥不可及的！点这里，告诉你满分是如何炼成的Warm and wet13. Geigl herself believes that， with cooperation between bench and field researchers， preserving fossils properly could open up avenues of discovery that have long been assumed closed.14. Much human cultural development took place in temperate regions. DNA does not survive well in warm environments in the first place， and can vanish when fossils are washed and treated. For this reason， Geigl says， most ancient DNA studies have been done on permafrost samples， such as the woolly mammoth， or on remains sheltered from the elements in cold caves — including cave bear and Neanderthal fossils.15. Better conservation methods， and a focus on fresh fossils， could boost DNA extraction from more delicate specimens， says Geigl. And that could shed more light on the story of human evolution.(640 words nature )GlossaryPalaeontologists 古生物学家Aurochs 欧洲野牛Neanderthal (人类学)尼安德特人，旧石器时代的古人类。

2014年雅思阅读模拟试题(1)When was the last time you saw a frog? Chances are, if you live in a city, you have not seen one for some time. Even in wet areas once teeming with frogs and toads, it is BEComing less and less easy to find those slimy, hopping and sometimes poisonous members of the animal kingdom. All over the world, and even in remote parts of Australia, frogs are losing the ecological battle for survival, and biologists are at a loss to explain their demise. Are amphibians simply oversensitive to changes in the ecosystem? Could it be that their rapid decline in numbers is signaling some coming environmental disaster for us all? This frightening scenario is in part the consequence of a dramatic increase over the last quarter century in the development of once natural areas of wet marshland; home not only to frogs but to all manner of wildlife. However, as yet, there are no obvious reasons why certain frog species are disappearing from rainforests in Australia that have barely been touched by human hand. The mystery is unsettling to say the least, for it is known that amphibian species are extremely sensitive to environmental variations in temperature and moisture levels. The danger is that planet Earth might not only lose a vital link in the ecological food chain (frogs keep populations of otherwise pestilent insects at manageable levels), but we might be increasing our output of air pollutants to levels that may have already become irreversible. Frogs could be inadvertently warning us of a catastrophe.An example of a species of frog that, at far as is known, has become extinct, is the platypus frog. Like the well-known Australian mammal it was named after, it exhibited some very strange behaviour; instead of giving birth to tadpoles in the water, it raised its young within its stomach. The baby frogswere actually born from out of their mother's mouth. Discovered in 1981, less than ten years later the frog had completely vanished from the crystal clear waters of Booloumba Creek near Queensland's Sunshine Coast. Unfortunately, this freak of nature is not the only frog species to have been lost in Australia. Since the 1970s, no less than eight others have suffered the same fate.One theory that seems to fit the facts concerns the depletion of the ozone layer, a well documented phenomenon which has led to a sharp increase in ultraviolet radiation levels.The ozone layer is meant to shield the Earth from UV rays, but increased radiation may be having a GREater effect upon frog populations than previously believed. Another theory is that worldwide temperature increases are upsetting the breeding cycles of frogs.TRUE/FALSE/NOT GIVEN1.Frogs are disappearing only from city areas.2.Frogs and toads are usually poisonous.3.Biologists are unable to explain why frogs are dying.4.The frogs' natural habitat is becoming more and more developed.5.Attempts are being made to halt the development of wet marshland.6.Frogs are important in the ecosystem because they control pests.7.The platypus frog became extinct by 1991.8.Frogs usually give birth to their young in an underwater nest.9.Eight frog species have become extinct so far in Australia.10.There is convincing evidence that the ozone layer is being depleted.11.It is a fact that frogs' breeding cycles are upset by worldwide in creases in temperature.Answer Keys：1.F 2.F 3.T 4.T 5.NG 6.T 7.T 8.NG 9.F 10.T 11.F2014年雅思阅读模拟试题(2)Almost everyone with or without a computer is aware of the latest technological revolution destined to change forever the way in which humans communicate, namely, the Information Superhighway, best exemplified by the ubiquitous Internet. Already, millions of people around the world are linked by computer simply by having a modem and an address on the `Net', in much the same way that owning a telephone links us to almost anyone who pays a phone bill. In fact, since the computer connections are made via the phone line, the Internet can be envisaged as a network of visual telephone links. It remains to seen in which direction the Information Superhighway is headed, but many believeit is the educational hope of the future.The World Wide Web, an enormous collection of Internet addresses or sites, all of which can be accessed for information, has been mainly responsible for the increase in interest in the Internet in the 1990s. Before the World Wide Web, the `Net' was comparable to an integrated collection of computerized typewriters, but the introduction of the `Web' in 1990 allowed not only text links to be made but also graphs, images and even video.A Web site consists of a `home page', the first screen of a particular site on the computer to which you are connected, from where access can be had to other subject related `pages'(or screens) at the site and on thousands of other computers all over the world. This is achieved by a process called `hypertext'. By clicking with a mouse device on various parts of the screen, a person connected to the `Net' can go traveling, or surfing' through a of the screen, a person connected to the `Net' can go traveling, or `surfing' through a web of pages to locate whatever information is required.Anyone can set up a site; promoting your club, your institution, your company's products or simply yourself, is what the Web and the Internet is all about. And what is more, information on the Internet is not owned or controlled by any one organization. It is, perhaps, true to say that no one and therefore everyone owns the `Net'. BECause of the relative freedom of access to information, the Internet has often been criticised by the media as a potentially hazardous tool in the hands of young computer users. This perception has proved to be largely false however, and the vast majority of users both young and old get connected with the Internet for the dual purposes for which it was intended - discovery and delight.TRUE/FALSE/NOT GIVEN1.Everyone is aware of the Information Superhighway.ing the Internet costs the owner of a telephone extra money.3.Internet computer connections are made by using telephone lines.4.The World Wide Web is a network of computerised typewriters.5.According to the author, the Information Superhighway may be the future hope of education.6.The process called`hypertext'requires the use of a mouse device.7.The Internet was created in the 1990s.8.The `home page'is the first screen of a `Web'site on the `Net'.9.The media has often criticised the Internet because it is dangerous.10.

The failure of a high-profile cholesterol drug has throwna spotlight on the complicated machinery that regulates cholesterol levels. But many researchers remain confident that drugs to boost levels of ’good’ cholesterol are still one of the most promising means to combat spiralling heart disease.2. Drug company Pfizer announced on 2 December that it was cancelling all clinical trials of torcetrapib， a drug designed to raise heart-protective high-density lipoproteins (HDLs)。

1. A European spacecraft took off today to spearhead the search for another "Earth" among the stars.2. The Corot space telescope blasted off aboard a Russian Soyuz rocket from the Baikonur cosmodrome in Kazakhstan shortly after 2.20pm.3. Corot , short for convection rotation and planetary transits , is the first instrument capable of finding small rocky planets beyond the solar system. Any such planet situated in the right orbit stands a good chance of having liquid water on its surface, and quite possibly life, although a leading scientist involved in the project said it was unlikely to find "any little green men".4. Developed by the French space agency , CNES, and partnered by the European Space Agency (ESA, Austria, Belgium, Germany, Brazil and Spain, Corot will monitor around 120, 000 stars with its 27cm telescope from a polar orbit 514 miles above the Earth. Over two and a half years , it will focus on five to six different areas of the sky , measuring the brightness of about 10, 000 stars every 512 seconds.5. "At the present moment we are hoping to find out more about the nature of planets around stars which are potential habitats. We are looking at habitable planets , not inhabited planets. We are not going to find any little green men, " Professor Ian Roxburgh , an ESA scientist who has been involved with Corot since its inception, told the BBC Radio 4 Today programme.6. Prof Roxburgh said it was hoped Corot would find "rocky planets that could develop an atmosphere and , if they are the right distance from their parent star , they could have water".7. To search for planets , the telescope will look for the dimming of starlight caused when an object passes in front of a star, known as a "transit". Although it will take more sophisticated space telescopes planned in the next 10 years to confirm the presence of anEarth-like planet with oxygen and liquid water, Corot will let scientists know where to point their lenses.8. Measurements of minute changes in brightness will enable scientists to detect giant Jupiter-like gas planets as well as small rocky ones. It is the rocky planets - that could be no bigger than about twice the size of the Earth - which will cause the most excitement. Scientists expect to find between 10 and 40 of these smaller planets.9. Corot will also probe into stellar interiors by studying the acoustic waves that ripple across the surface of stars, a technique called "asteroseismology".10. The nature of the ripples allows astronomers to calculate a star ’ s precise mass , age and chemical composition.11. "A planet passing in front of a star can be detected by the fall in light from that star. Small oscillations of the star also produce changes in the light emitted , which reveal what the star is made of and how they are structured internally. This data will provide a major boost to our understanding of how stars form and evolve , " Prof Roxburgh said.12. Since the discovery in 1995 of the first "exoplanet" - a planet orbiting a star other than the Sun - more than 200 others have been found by ground-based observatories.13. Until now the usual method of finding exoplanets has been to detect the "wobble" their gravity imparts on parent stars. But only giant gaseous planets bigger than Jupiter can be found this way, and they are unlikely to harbour life.14. In the 2010s , ESA plans to launch Darwin , a fleet of four or five interlinked space telescopes that will not only spot small rocky planets, but analyse their atmospheres for signs of biological activity.15. At around the same time , the US space agency , Nasa, will launch Terrestrial Planet Finder, another space telescope designed to locate Earth-like planets. Choose the appropriate letter from A-D for question 1.1.
