2019年雅思IELTS考试备考资料模拟试题及答案14The nervous system of vertebrates is characterized by a hollow, dorsal nerve cord that ends in the head region as an enlargement, the brain. Even in its most primitive form this cord and its attached nerves are the result of evolutionary specialization, and their further evolution from lower to higher vertebrate classes is a process that is far from fully understood. Nevertheless, the basic arrangements are similar in all vertebrates, and the study of lower animals gives insight into the form and structure of the nervous system of higher animals. Moreover, for any species, the study of the embryological development of the nervous system is indispensable for an understanding of adult morphology.In any vertebrate two chief parts of the nervous system may be distinguished. These are the central nervous system (the nerve cord mentions above), consisting of the brain and spinal cord, and the peripheral nervous system, consisting of the cranial, spinal, and peripheral nerves, together with their motor and sensory endings. The term "autonomic nervous system" refers to the parts of the central and peripheral systems that supply and regulate the activity of cardiac muscle, smooth muscle, and many glands.The nervous system is composed of many millions of nerve and glial cells, together with blood vessels and a small amount of connective tissue. The nerve cells, or "neurons", are characterized by many processes and are specialized in that they exhibit to a great degree the phenomena ofirritability and conductivity. The glial cells of the central nervous system are supporting cells collectively termed"neuroglia". They are characterized by short processes that have special relationships to neurons, blood vessels, and connective tissue. The comparable cells in the peripheral nervous system are termed "neurilemmal" cells.1. What does the passage mainly discuss?(A) The parts of a neuron(B) The structure of animals' nerve(C) The nervous system of vertebrates(D) The development of the brain2. According to the passage , the nerve cord of vertebrates is(A) large(B) hollow(C) primitive(D) embryological3. The author implies that a careful investigation of a biological structure in an embryo may(A) Improved research of the same structure in other species(B) A better understanding of the fully developed structure(C) Discovering ways in which poor development can be corrected(D) A method by which scientists can document the various stages of development4. The two main parts of the central nervous system are the brain and the(A) sensory endings(B) cranial nerve(C) spinal cord(D) peripheral nerves5. All of the following are described as being controlled by the autonomic nervous system EXCEPT(A) connective tissue(B) cardiac muscle(C) glandular activity(D) smooth muscle6. In what lines does the author identify certain characteristic of nerve cells?(A) lines 1-2(B) lines 9-12(C) lines 12-14(D) lines 16-18CBBCA D。

Section1青春期能力发展（重复19年4月13日第一篇文章，考试文章和部分题目稍有改动，真题仅供参考）Section2蜜蜂对于生态的重要性Section3可以参考：历史教学新方法 New Ways of Teaching HistoryNew Ways of Teaching HistoryIn a technology and media-driven world， it＇s becoming increasinglydifficult to get ou r students’attentions andkeep them absorbed in classroom discussions. This generation， in particular，has brought a unique set of challenges to the educational table. Whereas youthare easily enraptured by high-definition television， computers，iPods， videogames and cell phones， they are less than enthralled by what to them areobsolete textbooks and boring classroom lectures. The question of how to teachhistory in a digital age is often contentious. On the one side， the old guardthinks the professional standards history is in mortal danger fromflash-in-the-pan challenges by the distal that are all show and no the other Side， the self-styled “disruptors”offer over-blown rhetoric about how digital technology has changedeverything while the moribund profession obstructs all progress in the name ofoutdated ideals. At least， that＇s a parody （maybe not much of one） of how thedebate proceeds. Both supporters and opponents of the digital share moredisciplinary common ground thaneither admits.When provided with merely a textbook as a supplemental learning tool， testresults have revealed that most students fail to pinpoint the significance ofhistorical events and individuals. Fewer still are ableto cite andsubstantiate primary historical sources. What does this say about the way oureducators are presenting information？ The quotation comes from a report of a1917 test of 668 Texas students. Less than 10 percent of school-age childrenattended high school in 1917； today，enrollments are nearly universal. Thewhole world has turned on its head during the last century but one thing hasstayed the same： Young people remain woefully ignorant about history reflectedfrom their history tests.Guess what？ Historians are ignorant too， especiallywhen we equate historical knowledge with the ＂Jeopardy＂ Daily a test， those specializing in American history did just fine. But thosewithspecialties in medieval， European and African history failed miserably whenconfronted by items about Fort Ticonderoga， the Olive Branch Petition， or theQuebec Act —all taken from a typical textbook. According to thetesters， the results from the recent National Assessment in History， likescores from earlier tests， show that young people are ＂abysmallyignorant＂ of their own history. Invoking the tragedy of last September，historian Diane Ravitch hitched her worries about our future to the idea thatour nation＇s strength is endangered by youth who do poorly on such tests. Butif she were correct， we could have gone down the tubes in 1917！There is a huge difference between saying ＂Kids don’t know the history we want then to know＂ and saying ＂Kids don＇tknow history at all.＂ Historical knowledge burrows itself into ourcultural pores evenif young people can＇t marshal it when faced by a multiplechoice test.If we we ren’t such hypocrites（or maybe if we were better historians）we＇d have to admit that today＇sstudents follow in our own footsteps. For too long we＇ve fantasized that byrewriting textbooks we could change how history is learned. The problem，however， is not the content of textbooks but the very idea of them. No humanmind could retain the information crammed into these books in 1917， and it cando no better now. If we have learned anything from history that can be appliedto every time period， it is that the only constant is change. The teaching ofhistory， or any subject for that matter， is no exception. The question is nolonger whether to bring new technologies into everyday education； now， thequestion is which There is a huge difference between saying ＂Kids don’t know the history we want then to know＂ and saying ＂Kids don＇tknow history at all.＂ Historical knowledge burrows itself into ourcultural pores even if young people can＇t marshal it when faced by a multiplechoice test. If we weren’t such hypocrites（or maybe if we were better historians） we＇d have to admit that today＇sstudents follow in our own footsteps. For too long we＇ve fantasized that byrewriting textbooks we could change how history is learned. The problem，however， is not the content of textbooks but the very idea of them.

If we have learned anything from history that can be appliedto every time period， it is that the only constant is change. The teaching ofhistory， or any subject for thatmatter， is no exception. The question is nolonger whether to bring new technologies into everyday education； now， thequestion is which technologies are most suitable for the range of topicscovered in junior high and high school history classrooms. Fortunately，technology has provided us with opportunities to present our Civil War lessonplans or our American Revolution lesson plans in a variety of new ways.Teachers can easily target and engage the learners of this generation byeffectively combining the study of history with innovative multimedia- PowerPointand presentations in particular can expand the scope of traditional classroomdiscussion by helping teachers to explain abstract concepts while accommodatingstudents* unique learning styles. PowerPoint study units that have beenpre-made for history classrooms include all manner of photos， prints， maps，audio clips， video clips and primary sources which help to make learninginteractive and stimulating. Presenting lessons in these enticing formats helpstechnology-driven students retain the historical information they＇ll need toknow for standard exams.Whether you are covering Revolutionary War lesson plans or World War IIlesson plans， PowerPoint study units are available in formats to suit the needsof your classroom. Multimedia teaching instruments like PowerPoint software aregetting positive results the world over， framing conventional lectures withcaptivating written， auditory and visual content that helps students recallnames， dates and causal relationships within a historical context.History continues to show us that new times bring new realities. Educationis no exception to the rule. The question is not whether to bring technologyinto the educational environment. Rather， the question is which technologiesare suitable for U.S. and world history subjects，from Civil War lesson plansto World War II lesson plans. Whether you’re covering your American Revolution lesson plans or your Cold War lessonplans， PowerPoint presentations are available in pre-packaged formats to suityour classroom＇s needs.Meanwhile， some academic historians hold a different view on the use oftechnology in teaching history. One reason they hold is that not all facts canbe recorded by film or videos and literature is relatively feasible in thiscase her challenge they have to be faced with is the painful process tolearn new technology like the making ofPowerPoint and the editing of audio andvideo clips which is also reasonable especially to some elderly historians.QuestionReading this passage has eight paragraphs， A- GChoosing the correct heading for paragraphs A- G from the list of headingbelowWrite the appropriate number， i- x， in boxes 28-34 on your answer sheetList of Headingsi unavoidable changing facts to be considered when picking up technologymeansii A debatable place where the new technologies stand in for historyteachingiii Hard to attract students in traditional ways of teaching historyiv Display of the use of emerging multimedia as leaching toolsv Both students and professionals as candidates did not produce decentresultsvi A good concrete example illustrated to show how multimedia animates thehistory classvii The comparisons of the new technologies applied in history classviii Enormous breakthroughs in new technologiesix Resistance of using new technologies from certain historianx Decisions needed on which technique to be used for history teachinginstead of improvement in the textbooks28 Paragraph A29 Paragraph B30 Paragraph C31 Paragraph D32 Paragraph E33 Paragraph F34 Paragraph GQuestion 35-37Do the following statements agree with the information given in ReadingPassage？In boxes 35-37 on your answer sheet， writeYES if the statement is trueNO if the statement is falseNOT GIVEN if the information is not given in the passage35 Modem people are belter at memorizing historical information comparedwith their ancestors.36 New technologies applied in history- teaching are more vivid forstudents to memorize the details of historical events.37 Conventional ways like literature arc gradually out of fashion as timegoes by.Question 38-40Complete the following summary of the paragraphs of Reading Passage， usingmore than three words from the Reading Passage for each answer.Write your answers in boxes 38-40 on your answer sheet.Contemporary students can be aimed at without many difficulties byintegrating studying history with novel. ..38....

The family had extensive landholdings in Scotland. Besides its residence in Edinburgh， it owned Press Estate， 650 acres of farmland about 35 miles southeast of the city. The family often stayed at Press Castle， the large mansion on the northern edge of the property， and Alexander spent much of his childhood in the area，playing on the beach near Eyemouth or fishing in the streams nearby.Even after he went to school at Murcheston Academy on the outskirts of Edinburgh， Henderson returned to Press at weekends. In 1849 he began a three-year apprenticeship to become an accountant. Although he never liked the prospect of a business career， he stayed with it to please his family. In October 1855， however， he emigrated to Canada with his wife Agnes Elder Robertson and they settled in Montreal.Henderson learned photography in Montreal around the year 1857 and quickly took it up as a serious amateur. He became a personal friend and colleague of the Scottish- Canadian photographer William Notman. The two men made a photographic excursion to Niagara Falls in 1860 and they cooperated on experiments with magnesium flares as a source ofartificial light in 1865. They belonged to the same societies and were among the founding members of the Art Association of Montreal. Hendersonacted as chairman of the association＇s first meeting， which was heldin Notman＇s studio on 11 January 1860.In spite of their friendship， their styles of photography were quite e Notman＇s landscapes were noted for their bold realism，Henderson for the first 20 years of his career produced romantic images， showing the strong influence of the British landscape tradition. His artistic and technical progress was rapid and in 1865 he published his first major collection of landscape publication had limited circulation （only seven copies have ever been found）， and was called Canadian Views and contents of each copy vary significantly and have proved a useful source for evaluating Henderson＇s early work.In 1866， he gave up his business to open a photographicstudio， advertising himself as a portrait and landscape photographer. From about 1870 he dropped portraiture to specialize in landscape photography and other views. His numerous photographs of city life revealed in street scenes， houses， and markets are alive with human activity， and although his favourite subject was landscape he usually composed his scenes around such human pursuits as farming the land，cutting ice on a river， or sailing down a woodland stream. There was sufficient demand for these types of scenes and others he took depicting the lumber trade， steamboats and waterfalls to enable him to make a living. There was little competing hobby or amateur photography before the late 1880s because of the time-consuming techniques involved and the weight of the equipment. People wanted to buy photographs as souvenirsof a trip or as gifts， and catering to this market， Henderson hadstock photographs on display at his studio for mounting， framing， or inclusion in albums.Henderson frequently exhibited his photographs in Montreal and abroad， in London， Edinburgh， Dublin， Paris， New York， and Philadelphia. He met with greater success in 1877 and 1878 in New York when he won first prizes in the exhibition held by E and H T Anthony and Company for landscapes using the Lambertype process. In 1878 his work won second prize at the world exhibition in Paris.In the 1870s and 1880s Henderson travelled widely throughout Quebec and Ontario， in Canada， documenting the major cities of the two provinces and many of the villages in Quebec. He was especially fond of the wilderness and often travelled by canoe on the Blanche， du Lievre，and other noted eastern rivers. He went on several occasions to theMaritimes and in 1872 he sailed by yacht along the lower north shore of the St Lawrence River. That same year， while in the lower St Lawrence River region， he took some photographs of the construction of the lntercolonial Railway. This undertaking led in 1875 to a commission from the railway to record the principal structures along the almost-completed line connecting Montreal to Halifax. Commissions from other railways followed. In 1876 he photographed bridges on the Quebec，Montreal， Ottawa and Occidental Railway between Montreal and Ottawa. In 1885 he went west along the Canadian Pacific Railway （CPR） as far as Rogers Pass in British Columbia， where he took photographs of the mountains and the progress of construction.In 1892 Henderson accepted a full-time position with the CPR as manager of a photographic department which he was to set up and administer. His duties included spending four months in the field each year. That summer he made his second trip west， photographing extensively along the railway line as far as Victoria. He continued in this post until 1897， when he retired completely from photography.When Henderson died in 1913， his huge collection of glass negatives was stored in the basement of his house. Today collections of his work are held at the National Archives of Canada， Ottawa， and the McCord Museum of Canadian History， Montreal.题型难度及技巧分析这篇文章在三篇文章当中看上去和第二篇文章有点类似，但是从雅思真题的这篇文章来看，第二篇文章更加偏向于科技而不是强调人工智能。

2019年雅思考试阅读模拟试题：段落标题(1)Volcanoes-earth-shattering newsWhen Mount Pinatubo suddenly erupted on 9 June 1991, the power of volcanoes past and present again hit the headlinesAVolcanoes are the ultimate earth-moving machinery. 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 floorhas a basement of volcanic basalt.Volcanoes have not only made the continents, they arealso 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 yearthey add two or three cubic kilometres of rock to the continents. Imagine a similar number of volcanoes smokingaway 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.BGeologists 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. These fracture zones, where the collisions occur, are where earthquakes happen. And, very often, volcanoes.CThese 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 northern 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 the 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' where 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.DBut 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 Mont Pelée in Martinique at7.49 a.m. on 8 May, 1902. Of a town of 28,000, only two people survived. In 1815, a sudden blast removed the top1,280 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 faded, after snowin June and frosts in August. Volcanoes are potentially world news, especially the quiet ones.。

The Tsarist control and isolationism in Russia allowed for little influence from the West. It wasn＇t until the rise of Peter the Great that Russiansociety opened up to the West. St. Petersburg was erected to embrace the West and compete against Moscow’s isolationism. Peter the Great created a new Russia which rivaled the society of the West with magnificent courts and palaces. His vision was to challenge the west. Classical ballet entered the realm of Russia not as entertainment，but as a “standard of physical comportment to be emulated and internalized-an idealized way of behaving. The aim was not to entertain the masses of Russians，but to create a cultivated and new Russian people.Empress Anna，（1730 –1740）was devoted to ostentatious amusements （balls， fireworks， tableaux）， and in the summer of 1734 ordered the appointment of Jean-Baptiste Landé as dancing-master in the military academy she had founded in 1731 for sons of the nobility. In 1738， he became ballet master and head of the new ballet school， launching the advanced study of ballet in Russia， and winning the patronage of elite families.France provided many leaders such as Charles Didelot in St Petersburg （1801-1831），Jules Perrot（1848-1859）and Arthur Saint-Léon （1859-69）.In the early 19th century， the theaters were opened up to anyone who could afford a ticket. A seating section called a rayok，or ＇paradise gallery＇， consisted of simple wooden benches. This allowed non-wealthy people access to the ballet， because tickets in this section were inexpensive.One author describes the Imperial ballet as “unlike that of any other country in the world…the most prestigious of the ballet troupes were those attached to the state-supported theatres. The directors of these companies were personally appointed by the tsar， and all the dancers were， in a sense， Imperial servants.In the theatre，the men in the audience always remained standing until the tsar entered his box and，out of respect，after the performance they remained in their places until he had departed.

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.。

2019年雅思阅读模拟题精选及答案A“Your battery is now fully charged”, Announced the laptop computer to its owner, Donald A Norman, with enthusiasm-perhaps even a hint of pride?---in its synthetic voice. To be sure, distractions and multitasking are hardly new to the human condition. “A complicated life, continually interrupted by computing requests for attention, is as old as procreation,”laughs Ted Selker of the Massachusetts Institute of TechnologyMedia Lab. But increasingly, it is not just our kids pulling us three ways at once; it is also a relentless barrage of e-mail, alerts, alarms, calls, instant messages and automated notifications, none of them coordinated and all of them oblivious to whether we are busy—or even present. “It’s ridiculous that my own computer can’t figure out whether I’m in front of it, but a public toilet can,”exclaims Roel Vertegaal of Queen’s University in Ontario.BHumanity has connected itself through roughly three billion networked telephones, computers traffic lights—even refrigerators and picture frame—because these things make life more convenient and keep us available to those we care about. So although we could simply turn off the phones, close the e-mail program, and shut the office door when it is time for meeting or strench of concentrated work, we usuallydon’t. We just endure the consequences.CNumerous studies have shown that when people are unexpectedly interrupted, they not only work less efficiently but also make more mistakes. “It seems to add cumulatively to a feeling of frustration,”Picard reports, and that stress response makes it hard to regain focus. It isn’t merely a matter of productivity and the pace of life. For pilots, drivers, soldiers and doctors, errors of inattention can be downright dangerous. “If we could just give our computers and phones some understanding of the limits of human attention and memory, it would make them seem a lot more thoughtful and courteous,”says Eric Horvitz of Microsoft Research. Horvitz, Vertegaal, Selker and Picard are Eric Horvitz among a small but growing number of researchers trying to teach computers, phones, cars and other gadgets to behave less like egocentric oafs and more like considerate colleagues.D“Attentive”computing systems have begun appearing in newer Volvos and IBM has introduced Websphere communications software with a basic busyness sense. Microsoft has been running extensive in-house tests of a much more sophisticated system since 2003. Within a few year, companies may be able to offer every office worker a software version of the personal receptionist that only corner-suite executives。
