剑桥雅思12Test7雅思阅读passage 1参考译文——空运而来的乌龟推荐：剑桥雅思12Test7雅思阅读passage 1真题+解析空运的放归计划帮助环保者采取重要措施保护瀕危的加拉帕戈斯电A 起伏不平的火山岩平原上大部分覆盖着多刺的仙人掌丛林，正是这片平原将加拉幀戈斯的伊莎贝拉岛的内陆与太平洋分隔开来。
岛上散布着五座迥异的火山，这使得它的地貌如月球一般。
只有谢拉?内格拉火山云雾缭绕的山峰周围茂密的植被才使得山下贫瘠的地势显得不那么单调。
这种恶劣的环境是加拉帕戈斯巨龟的栖息地。
在加拉幀戈斯群岛形成后的一段时间后，大约五百万年前，南美大陆上的一种或多种乌龟迁徙到该群岛。
随着这些祖辈的乌龟栖息于各个岛屿之上，不同的种群适应了它们各自独特的环境，产生了至少14种不同的亚种。
岛上的生活很适合它们。
在缺乏大型捕食者的条件下，它们长成了世界上最大最长寿的乌龟，重达400多公斤，个别的超过1.8米长，寿命超过一个世纪。
B 在人类抵达之前，群岛上的乌龟以数十万计。
自17世纪以来，海盗捕获了一些乌龟并带上船食用，但自18世纪90年代以来捕鲸船的到来见证了这种掠夺急剧性地增长。
这些巨龟相对不爱活动，并且在缺乏饮食的情况下也能生存数月之久，因此它们被捕上船充当海上漫长航行的食物补给。
有时它们的肉体被加工成优质的油料。
总计在20 世纪之前从该群岛上捕走了约20万只动物。
这种历史上的掠夺在定居者到来之后更加变衣加厉:人们猎捕巨龟并破坏了它们的栖息地以开荒种地。
他们还带来了外来物种——从牛羊猪狗和老鼠到植物和蚂蚁——这些物种要么以巨龟卵和小巨龟为食，要么破坏它们的栖息地。
C 目前只有11种原始的亚种巨龟存活，并且其中有一些是高度濒危的。
1989年伊莎贝拉岛上 Puerto Villamil城外的巨龟抚育中心开始运行，旨在保护该岛的巨龟种群数量。
该中心的捕猎繁育计划结果非常成功，最终它不得不面对种群数量过大的问题。
D 这个问题也曾是个迫切的问题。

剑桥雅思阅读4原文(test3)READING PASSAGE 1You should spend about 20 minutes on Questions 1-13 which are based on Reading Passage 1 below.Micro-Enterprise Credit for Street Youth‘I am from a large, poor family and for many years we have done without breakfast. Ever since I joined the Street Kids International program I have been able to buy my family sugar and buns for breakfast. I have also bought myself decent second-hand clothes and shoes.’Doreen Soko‘We’ve had business experience. Now I’m confident to expand what we’ve been doing. I’ve learnt cash management, and the way of keeping money so we save for re-investment. Now business is a part of our lives. As well, we didn’t know each other before —now we’ve made new friends.’Fan KaomaParticipants in the Youth Skills Enterprise Initiative Program, ZambiaIntroductionAlthough small-scale business training and credit programs have become more common throughout the world, relatively little attention has been paid to the need to direct such opportunities to young people. Even less attention has been paid to children living on the street or in difficult circumstances.Over the past nine years, Street Kids International (S.K.I.) hasbeen working with partner organisations in Africa, Latin America and India to support the economic lives of street children. The purpose of this paper is to share some of the lessons S.K.I. and our partners have learned.BackgroundTypically, children do not end up on the streets due to a single cause, but to a combination of factors: a dearth of adequately funded schools, the demand for income at home, family breakdown and violence. The street may be attractive to children as a place to find adventurous play and money. However, it is also a place where some children are exposed, with little or no protection, to exploitative employment, urban crime, and abuse.Children who work on the streets are generally involved in unskilled, labour-intensive tasks which require long hours, such as shining shoes, carrying goods, guarding or washing cars, and informal trading. Some may also earn income through begging, or through theft and other illegal activities. At the same time, there are street children who take pride in supporting themselves and their families and who often enjoy their work. Many children may choose entrepreneurship because it allows them a degree of independence, is less exploitative than many forms of paid employment, and is flexible enough to allow them to participate in other activities such as education and domestic tasks.Street Business PartnershipsS.K.I. has worked with partner organisations in Latin America, Africa and India to develop innovative opportunities for street children to earn income.The S.K.I. Bicycle Courier Service first started in the Sudan. Participants in this enterprise were supplied with bicycles, whichthey used to deliver parcels and messages, and which they were required to pay for gradually from their wages. A similar program was taken up in Bangalore, India.Another successful project, The Shoe Shine Collective, was a partnership program with the Y.W.C.A. in the Dominican Republic. In this project, participants were lent money to purchase shoe shine boxes. They were also given a safe place to store their equipment, and facilities for individual savings plans.The Youth Skills Enterprise Initiative in Zambia is a joint program with the Red Cross Society and the Y.W.C.A. Street youths are supported to start their own small business through business training, life skills training and access to credit.Lessons learnedThe following lessons have emerged from the programs that S.K.I. and partner organisations have created.Being an entrepreneur is not for everyone, nor for every street child. Ideally, potential participants will have been involved in the organisation’s programs for at least six months, and trust and relationship-building will have already been established.The involvement of the participants has been essential to the development of relevant programs. When children have had a major role in determining procedures, they are more likely to abide by and enforce them.It is critical for all loans to be linked to training programs that include the development of basic business and life skills.There are tremendous advantages to involving parents or guardians in the program, where such relationships exist. Home visits allow staff the opportunity to know where the participants live, and to understand more about each individual’s situation.Small loans are provided initially for purchasing fixed assetssuch as bicycles, shoe shine kits and basic building materials for a market stall. As the entrepreneurs gain experience, the enterprises can be gradually expanded and consideration can be given to increasing loan amounts. The loan amounts in S.K.I. programs have generally ranged from US$30-$100.All S.K.I. programs have charged interest on the loans, primarily to get the entrepreneurs used to the concept of paying interest on borrowed money. Generally the rates have been modest (lower than bank rates).ConclusionThere is a need to recognise the importance of access to credit for impoverished young people seeking to fulfil economic needs. The provision of small loans to support the entrepreneurial dreams and ambitions of youth can be an effective means to help them change their lives. However, we believe that credit must be extended in association with other types of support that help participants develop critical life skills as well as productive businesses.Questions 1-4Choose the correct letter, A, B, C or D.Write your answers in boxes 1-4 on your answer sheet.1 The quotations in the box at the beginning of the articleA exemplify the effects of S.K.I.B explain why S.K.I. was set up.C outline the problems of street children.D highlight the benefits to society of S.K.I.2 The main purpose of S.K.I. is toA draw the attention of governments to the problem of street children.B provide school and social support for street children.C encourage the public to give money to street children.D give business training and loans to street children.3 Which of the following is mentioned by the writer as a reason why children end up living on the streets?A unemploymentB warC povertyD crime4 In order to become more independent, street children mayA reject paid employment.B leave their families.C set up their own businesses.D employ other children.Questions 5-8Complete the table below.Choose NO MORE THAN THREE WORDS from Reading Passage 1 for each answer.Write your answers in boxes 5-8 on your answer sheet.Country Organisations Involved Type of Project Support Provided5………………and………………S.K.I courier service ? provision of 6………………………Dominican Republic ?

A violent eruption can blow the top few kilometres off a mountain, scatter fine ash practically all over the globe and hurl rock fragments into the stratosphere to darken the skies a continent away.But the classic eruption — cone-shaped mountain, big bang, mushroom cloud and surges of molten lava — is only a tiny part of a global story. Vulcanism, the name given to volcanic processes, really has shaped the world. Eruptions have rifted continents, raised mountain chains, constructed islands and shaped the topography of the earth. The entire ocean floor has abasement of volcanic basalt.Volcanoes have not only made the continents, they are also thought to have made the world’s first stable atmosphere and provided all the water for the oceans, rivers and ice-caps. There are now about 600 active volcanoes. Every year they add two or three cubic kilometres of rock to the continents. Imagine a similar number of volcanoes smoking away for the last 3,500 million years. That is enough rock to explain the continental crust.What comes out of volcanic craters is mostly gas. More than 90% of this gas is water vapour from the deep earth: enough to explain, over 3,500 million years, the water in the oceans. The rest of the gas is nitrogen, carbon dioxide, sulphur dioxide, methane, ammonia and hydrogen. The quantity of these gases, again multiplied over 3,500 million years, is enough to explain the mass of the world’s atmosphere. We are alive because volcanoes provided the soil, air and water we need.B Geologists consider the earth as having a molten core, surrounded by a semi-molten mantle and a brittle, outer skin. It helps to think of a soft-boiled egg with a runny yolk, a firm but squishy white and a hard shell. If the shell is even slightly cracked during boiling, the white material bubbles out and sets like a tiny mountain chain over the crack — like an archipelago of volcanic islands such as the Hawaiian Islands. But the earth is so much bigger and the mantle below is so much hotter.Even though the mantle rocks are kept solid by overlying pressure, they can still slowly ‘flow’ like thick treacle. The flow, thought to be in the form of convection currents, is powerful enough to fracture the ‘eggshell’ of the crust into plates, and keep them bumping and grinding against each other, or even overlapping, at the rate of a few centimetres a year. Thesefracture zones, where the collisions occur, are where earthquakes happen. And, very often, volcanoes.C These zones are lines of weakness, or hot spots. Every eruption is different, but put at its simplest, where there are weaknesses, rocks deep in the mantle, heated to 1,350℃, will start to expand and rise. As they do so, the pressure drops, and they expand and become liquid and rise more swiftly.Sometimes it is slow: vast bubbles of magma — molten rock from the mantle — inch towards the surface, cooling slowly, to show through as granite extrusions (as on Skye, or the Great Whin Sill, the lava dyke squeezed out like toothpaste that carries part of Hadrian’s Wall in no rthern England). Sometimes — as in Northern Ireland, Wales and the Karoo in South Africa —the magma rose faster, and then flowed out horizontally on to the surface in vast thick sheets. In the Deccan plateau in western India, there are more than two million cubic kilometres of lava, some of it 2,400 metres thick, formed over 500,000 years of slurping eruption.Sometimes the magma moves very swiftly indeed. It does not have time to cool as it surges upwards. The gases trapped inside the boiling rock expand suddenly, the lava glows with heat, it begins to froth, and it explodes with tremendous force. Then the slightly cooler lava following it begins to flow over the lip of the crater. It happens on Mars, it happened on the moon, it even happens on some of the moons of Jupiter and Uranus. By studying the evidence, vulcanologists can read the force of the great blasts of the past. Is the pumice light and full of holes? The explosion was tremendous. Are the rocks heavy, with huge crystalline basalt shapes, like t he Giant’s Causeway in Northern Ireland? It was a slow, gentle eruption.The biggest eruptions are deep on the mid-ocean floor, where new lava is forcing the continents apart and widening the Atlantic by perhaps five centimetres a year. Look at maps of volcanoes, earthquakes and island chains like the Philippines and Japan, and you can see the rough outlines of what are called tectonic plates —the plates which make up the earth’s crust and mantle. The most dramatic of these is the Pacific ‘ring of fire’ wh ere there have been the most violent explosions —Mount Pinatubo near Manila, Mount St Helen’s in the Rockies and El Chichón in Mexico about a decade ago, not to mention world-shaking blasts like Krakatoa in the Sunda Straits in 1883.D But volcanoes are not very predictable. That is because geological time is not like human time. During quiet periods, volcanoes cap themselves with their own lava by forming a powerful cone from the molten rocks slopping over the rim of the crater; later the lava cools slowly into a huge, hard, stable plug which blocks any further eruption until the pressure below becomes irresistible. In the case of Mount Pinatubo, this took 600 years.Then, sometimes, with only a small warning, the mountain blows its top. It did this at Mon t Pelée in Martinique at 7.49 a.m. on 8 May, 1902. Of a town of 28,000, only two people survived. In 1815, a sudden blast removed the top 1,280 metres of Mount Tambora in Indonesia. The eruption was so fierce that dust thrown into the stratosphere darkened the skies, cancelling the following summer in Europe and North America. Thousands starved as the harvests failed, after snow in June and frosts in August. Volcanoes are potentially world news, especially the quiet ones.Questions 18-21Answer the questions below using NO MORE THAN THREE WORDS AND/OR A NUMBER from the passage for each answer.Write your answers in boxes 18-21 on your answer sheet.18 What are the sections of the earth’s crust, often associated with volcanic activity, called?19 What is the name given to molten rock from the mantle?20 What is the earthquake zone on the Pacific Ocean called?21 For how many years did Mount Pinatubo remain inactive?Questions 22-26Complete the summary below.Choose NO MORE THAN TWO WORDS from the passage for each answer.Write your answers in boxes 22-26 on your answer sheet.Volcanic eruptions have shaped the earth’s land surface.

They range from a carefully planned, intensive field investigation in a foreign country to a casual introspection about one’s mother tongue carried out in an armchair at home.B In all cases, someone has to act as a source of language data — an informant. Informants are (ideally) native speakers of a language, who provide utterances for analysis and other kinds of information about the language (e.g. translations, comments about correctness, or judgements on usage). Often, when studying their mother tongue, linguists act as their own informants, judging the ambiguity, acceptability, or other properties of utterances against their own intuitions. The convenience of this approach makes it widely used, and it is considered the norm in the generative approach to linguistics. But a lin guist’s personal judgements are often uncertain, or disagree with the judgements of other linguists, at which point recourse is needed to more objective methods of enquiry, using non-linguists as informants. The latter procedure is unavoidable when working on foreign languages, or child speech.C Many factors must be considered when selecting informants —whether one is working with single speakers (a common situation when languages have not been described before), two people interacting, small groups or large-scale samples. Age, sex, social background and other aspects of identity are important, as these factors are known to influence the kind of language used. The topic of conversation and the characteristics of the social setting (e.g. the level of formality) are also highly relevant, as are the personal qualities of the informants (e.g. their fluency and consistency). For larger studies, scrupulous attention has been paid to the sampling theory employed, and in all cases, decisions have to be made about thebest investigative techniques to use.D Today, researchers often tape-record informants. This enables the linguist’s claims about the language to be checked, and provides a way of making those claims more accurate (‘difficult’ pieces of speech can be li stened to repeatedly). But obtaining naturalistic, good-quality data is never easy. People talk abnormally when they know they are being recorded, and sound quality can be poor. A variety of tape-recording procedures have thus been devised to minimise the ‘observer’s paradox’ (how to observe the way people behave when they are not being observed). Some recordings are made without the speakers being aware of the fact — a procedure that obtains very natural data, though ethical objections must be anticipated. Alternatively, attempts can be made to make the speaker forget about the recording, such as keeping the tape recorder out of sight, or using radio microphones. A useful technique is to introduce a topic that quickly involves the speaker, and stimulates a natural language style (e.g. asking older informants about how times have changed in their locality).E An audio tape recording does not solve all the linguist’s problems, however. Speech is often unclear and ambiguous. Where possible, therefore, the recording has to be supplemented by the observer’s written comments on the non-verbal behaviour of the participants, and about the context in general.A facial expression, for example, can dramatically alter the meaning of what is said. Video recordings avoid these problems to a large extent, but even they have limitations (the camera cannot be everywhere), and transcriptions always benefit from any additional commentary provided by an observer.F Linguists also make great use of structured sessions, inwhich they systematically ask their informants for utterances that describe certain actions, objects or behaviours. With a bilingual informant, or through use of an interpreter, it is possible to use translation techniques (‘How do you say table in your language?’). A large number of points can be covered in a short time, using interview worksheets and questionnaires. Often, the researcher wishes to obtain information about just a single variable, in which case a restricted set of questions may be used: a particular feature of pronunciation, for example, can be elicited by asking the informant to say a restricted set of words. There are also several direct methods of elicitation, such as asking informants to fill in the blanks in a substitution frame (e.g. I___ see a car), or feeding them the wrong stimulus for correction (‘Is it possible to say I no can see?’).G A representative sample of language, compiled for the purpose of linguistic analysis, is known as a corpus. A corpus enables the linguist to make unbiased statements about frequency of usage, and it provides accessible data for the use of different researchers. Its range and size are variable. Some corpora attempt to cover the language as a whole, taking extracts from many kinds of text; others are extremely selective, providing a collection of material that deals only with a particular linguistic feature. The size of the corpus depends on practical factors, such as the time available to collect, process and store the data: it can take up to several hours to provide an accurate transcription of a few minutes of speech. Sometimes a small sample of data will be enough to decide a linguistic hypothesis; by contrast, corpora in major research projects can total millions of words. An important principle is that all corpora, whatever their size, are inevitably limited in their coverage, and always need to be supplementedby data derived from the intuitions of native speakers of the language, through either introspection or experimentation.Questions 27-31Reading Passage 3 has seven paragraphs labeled A-G.Which paragraph contains the following information?Write the correct letter A-G in boxes 27-31 on your answer sheet.NB You may use any letter more than once.27 the effect of recording on the way people talk28 the importance of taking notes on body language29 the fact that language is influenced by social situation30 how informants can be helped to be less self-conscious31 various methods that can be used to generate specific dataQuestions 32-36Complete the table below.Choose NO MORE THAN THREE WORDS from the passage for each answer.Write your answers in boxes 32-36 on your answer sheet.METHODS OF OBTAINING LINGUISTIC DATA ADVANTAGES DISADVANTAGES32……as informant convenient method of enquiry not objective enoughNon-linguist as informant necessary with 33…… and child speech the number of factors to be consideredRecording an informant allows linguists’ claims to be checked 34……of soundVideoing an informant allows speakers’ 35…… to be observed 36……might mi ss certain thingsQuestions 37-40Complete the summary of paragraph G below.Choose NO MORE THAN THREE WORDS from the passage for each answer.Write your answers in boxes 37-40 on your answer sheet.A linguist can use a corpus to comment objectively on 37…… .

下面是一个关于雅思地图题的范文：The maps illustrate the changes that have taken place in a coastal area over a period of 60 years, between 1950 and 2010. The first map shows the area as it appeared in 1950, while the second map depicts the changes that have occurred by 2010.Overall, the most noticeable change is the development in the area. In 1950, the coast consisted mainly of natural features, including a sandy beach, some rocks, and a small area of vegetation. However, by 2010, the area had been transformed into a residential area with various buildings and infrastructure.In 1950, the beach occupied a large portion of the coastal area, extending from the northwest to the southeast. There were a few patches of vegetation scattered along the beach, particularly in the northeast corner. There were also a couple of rocks protruding from the water near the shore. On the other side of the beach, there was a small patch of flat land with some trees.By 2010, the beach had significantly reduced in size, with the sand giving way to residential buildings. In the northwest, there were a cluster of houses facing the beach, with a road running parallel to the coastline. Towards the southeast, there was a larger residential area, complete with a school, a shopping center, and a recreational park. The rocks that were present in 1950 had been removed to make way for a marina, where several boats and yachts weremoored.Furthermore, the area of vegetation in the northeast corner had been turned into a golf course, with well-manicured lawns and several ponds. The patch of flat land on the other side of the beach had been transformed into a golf driving range. In addition, a road had been constructed to connect the residential area to the rest of the city.In conclusion, the coastal area in question has undergone significant development over the past six decades. The beach has been overtaken by residential buildings, a marina has been built, and a large golf course and driving range have also been established.。

The HMS Erebus and HMS Terror were last seen in the late 1840s. Canada announced in 2008 that it would search for the ships ledby British Arctic explorer Sir John Franklin.Harper， speaking in Ottawa， said it remains unclear which ship has been found，but images show there＇s enough information to confirm it＇s one of the pair.Franklin and 128 hand-picked officers and men vanished on an expedition begun in 1845 to find the fabled Northwest Passage. Franklin＇s disappearance prompted one of history＇s largest and longest rescue searches， from 1848 to 1859， which resulted in the passage＇s discovery.The route runs from the Atlantic to the Pacific through the Arctic archipelago. European explorers sought the passage as a shorter route to Asia， but found it rendered inhospitable by ice and weather.＂This is truly a historic moment for Canada，＂ said Harper，who was beaming， uncharacteristically. ＂This has been a great Canadian story and mystery and the subject of scientists，historians，writers and singers so I think we really have an important day in mapping the history of our country.＂Harper＇s government began searching for Franklin＇s ships as it looked to assert Canada＇s sovereignty over the Northwest Passage，where melting Arctic ice has unlocked the very shipping route Franklin was after.The original search for the ships helped open up parts of the Canadian Arctic for discovery back in the 1850s. Harper said the ship was found Sunday using a remotely operated underwater vehicle. The discovery comes shortly after a team of archeologists found a tiny fragment from the Franklin expedition. Searchers discovered an iron fitting that once helped support a boat from one of the doomed expedition＇s ships in the King William Island search area.Franklin＇s vessels are among the most sought-after prizes in marine archaeology. Harper said the discovery would shed light on what happened to Franklin＇s crew.Tantalizing traces have been found over the years，including the bodies of three crewmen discovered in the 1980s.The bodies of two English seamen - John Hartnell， 25， and Royal Marine William Braine， 33 - were exhumed in 1986. An expedition uncovered the perfectly preserved remains of a petty officer， John Torrington， 20， in an ice-filled coffin in 1984.Experts believe the ships were lost in 1848 after they became locked in the ice near King William Island and that the crews abandoned them in a hopeless bid to reach safety.The search for an Arctic passage to Asia frustrated explorers for centuries，beginning with John Cabot＇s voyage in 1497. Eventually it became clear that a passage did exist， but was too far north for practical use. Cabot， the Italian-British explorer，died in 1498 while trying to find it and the shortcut eluded other famous explorers including Henry Hudson and Francis Drake. No sea crossing was successful until Roald Amundsen of Norway completed his trip from 1903-1906.P2 蜂王（英文标题待补充）文章主旨：待补充参考答案：待补充参考原文：待补充P3 Nature works for Nature Works™PLA新型塑料（2017.10.14旧题）文章主旨：对一种新型塑料的特性的介绍参考答案：判断27-30：27.

In the past，several efforts had been made to develop plastics from lactic acid，but with limited success. Achieving this technological breakthrough didn’t come easily， but in time the efforts did succeed. A fermentation and distillation process using com was designed to create a polymersuitable for a broad variety of applications.BAs an agricultural based firm， Cargill had taken this product as far as it could by 1997. The company needed a partner with access to plastics markets and polymerization capabilities， and began discussions with The Dow Chemical Company. The next step was the formation of the joint venture that created Cargill Dow LLC. Cargill Dow’s product is the world’s first commercially available plastic made from annually renewable resources such as com：Nature Works™ PLA is a family of packaging polymers （carbon-based molecules）made from non-petroleum based resources.Ingeo is a family of polymers for fibers made in a similar manner.CBy applying their unique technology to the processing of natural plant sugars，Cargill Dow has created a more environmentally friendly material that reaches the consumer in clothes，cups，packaging and other products. While Cargill Dow is a stand-alone business，it continues to leverage the agricultural processing， manufacturing and polymer expertise of the two parent companies in order to bring the best possible products to market.DThe basic raw materials for PLA are carbon dioxide and water. Growing plants， like com take these building blocks from the atmosphere and the soil. They are combined in the plant to make carbohydrates （sucrose and starch） through a process driven by photosynthesis. The process for making Nature Works PLA begins when a renewable resource such as corn is milled，separating starch from the raw material. Unrefined dextrose， inturn， is processed from the starch.ECargill Dow turns the unrefined dextrose into lactic acid using a fermentation process similar to that used by beer and wine producers. This is the same lactic acid that is used as a food additive and is found in muscle tissue in the human body. Through a special condensation process，a lactide is formed. This lactide is purified through vacuum distillation and becomes a polymer （the base for NatureWorks PLA） that is ready for use through a solvent-free melt process. Development of this new technology allows the company to “harvest” the carbon that living plants remove from the air through photosynthesis. Carbon is stored in plant starches，which can be broken down into natural plant sugars. The carbon and other elements in these natural sugars are then used to make NatureWorks PLA.FNature Works PLA fits all disposal systems and is fully compostable in commercial composting facilities. With the proper infrastructure， products made from this polymer can be recycled back to a monomer and re-used as a polymer. Thus， at the end of its life cycle， a product made from Nature Works PLA can be broken down into its simplest parts so that no sign of it remains.GPLA is now actively competing with traditional materials in packaging and fiber applications throughout the world； based on the technology’s success and promise，Cargill Dow is quickly becoming a premier player in the polymers market. This new polymer now competes head-on with petroleum-based materials like polyester. A wide range of products that vary inmolecular weight and crystallinity can be produced，and the blend of physical properties of PLA makes it suited for a broad range of fiber and packaging applications. Fiber and non-woven applications include clothing，fiberfill，blankets and wipes. Packaging applications include packaging films and food and beverage containers.HAs Nature Works PLA polymers are more oil- and grease-resistant and provide a better flavor and aroma barrier than existing petroleum-based polymers，grocery retailers are increasingly using this packaging for their fresh foods. As companies begin to explore this family of polymers，more potential applications are being identified. For example，PLA possess two properties that are particularly useful for drape fabrics and window furnishings. Their resistance to ultraviolet light is particularly appealing as this reduces the amount of fading in such fabrics， and their refractive index is low， which means fabrics constructed from these polymers can be made with deep colors without requiring large amounts of dye. In addition， sportswear makers have been drawn to the product as it has an inherent ability to take moisture away from the skin and when blended with cotton and wool， the result is garments that are lighter and better at absorbing moisture.IPLA combines inexpensive large-scale fermentation with chemical processing to produce a value-added polymer product that improves the environment as well. The source material for PLA is a natural sugar found in plants such as com and using such renewable feedstock presents several environmental benefits. As an alternative to traditional petroleum-based polymers，theproduction of PLA uses 20%-50% less fossil fuel and releases a lower amount of greenhouse gasses than comparable petroleumbased plastic；carbon dioxide in the atmosphere is removed when the feedstock is grown and is returned to the earth when the polymer is degraded. Because the company is using raw materials that can be regenerated year after year， it is both cost competitive and environmentally responsible.。
