A team of international scientists is due to set off for the world's biggest iceberg in a mission aiming to answer fundamental questions about the impact of climate change in the polar regions. The scientists, led by the British Antarctic Survey (BAS), are trying to reach a newly revealed ecosystem that had been hidden for 120,000 years below the Larsen C ice shelf.Last year, part of the Larsen C ice shelf calved (崩解) away, forming a huge iceberg-A68—which is four times bigger than London, and revealing life beneath for the first time. Now scientists say it is a race against time to explore these new ecosystems before they are transformed to the light. Marine biologist Dr Katrin Linse from the BAS is leading the mission."The calving of A68 provides us with a unique opportunity to study marine life as it responds to a huge environment change," she said. "It is important that we get there quickly before the undersea environment changes as sunlight enters the water."Professor David Vaughan, science director at the BAs, said, "We need to be bold (大胆的) on this one. Larsen C is a long way south and there's lots of sea ice in the area, but this is important science, so we will try our best to get the team where they need to be. He said climate change had already affected the sea around Antarctica and is warming some coastal waters. "Future warming may make some habitats warm. Where these habitats support unique species that are adapted to love the cold and not the warm, those species are going to either move or die."There is growing concern about the possible impact of climate change in the Antarctic. Earlier this month, a report revealed that melting ice sheets in Greenland and Antarctica are speeding up the already fast pace of the sea level rise. The research, published by the National Academies of Science, Engineering and Medicine, said, "At the current rate, the world's ocean will be, on average, at least 60cm higher by the end of the century." However, it found that the process is accelerating, and more than three quarters of the acceleration since 1993 is due to melting ice sheets in Greenland and Antarctica, the study shows.（1）Why are the scientists eager to go to the iceberg?A. To study how the iceberg was formed.B. To study a newly discovered ecosystem.C. To explore a new way to prevent climate change.D. To explore the geography of the Larsen C ice shelf.（2）What do the underlined words "this one" in the fourth paragraph refer to?A. The Larsen C ice shelf.B. Climate change in Antarctica.C. The A68 iceberg with the ecosystem beneath it.D. The condition of animal species in Antarctica.（3）What can we learn about the A68 iceberg from the text?A. It is as big as London.B. It is part of an ice shelf in the Arctic.C. It will disappear in a very short time.D. It has uncovered an unknown ecosystem in Antarctica.（4）What can we infer from the last paragraph?A. There is no need to worry about climate change in Antarctica.B. The ice sheets in Greenland and Antarctica are melting at a steady rate.C. Many creatures living in deep water will die out due to climate change.D. By 2100, the sea level will have risen to a much higher level than now.【答案】（1）B（2）C（3）D（4）D【解析】【分析】本文是一篇说明文，南极地区的拉森C冰架崩解形成了一座巨大的冰山A68 iceberg。

Two years ago, Li Yuhua's daughter taught her how to shop online. Since then, the 51-year-old farmer in Wushan has been a regular online shopper. Shoppers like Li Yuhua are the new target for China's ecommerce giants, including Alibaba Group, which operates the Taobao platform, and . Rural China added 3 million more Internet users in the first half, taking the total number to 225 million, or 26.3%, of the country's total Internet population of 854 million, according to a report on rural ecommerce development released last week by the China International Electronic Commerce Center. That helped improve rural online sales in the first half of the year by 21% to 777.1 billion yuan (US$109.6 billion), outpacing the national growth rate by 3.2 percentage points.''However, it is a little bit early to say that China's ecommerce battlefield is moving to rural China, '' said Chen Tao, a senior analyst at consultancy Analysys. Unlike urban residents, most rural Chinese haven’t experienced ecommerce shopping. While that provides online platforms with one of the last undeveloped markets for ecommerce, progress has been slow due to the lack of infrastructure(基础设施)and logistics(物流)support.To address that problem, China's second-largest ecommerce operator, hired more deliverymen and tested drone(无人机) delivery services to improve service in rural China. Alibaba Group, China's largest ecommerce player, announced in April last year that it had invested US$717 million in Huitongda Network Co., which helps to boost sales in 15,000 towns across 18 provinces.Another inhibiting factor in the development of rural ecommerce is the income gap. In 2018, annual per capita disposable income(人均可支配收入)in rural areas was 14,600 yuan (US$2,065) compared with 39,300 yuan (US$5,559) in cities. ''Lower disposable incomes in rural areas limit the consumption,'' said analyst Chen. ''It also takes time to educate rural residents to acceptecommerce services as most of them are new to online. There is still a long way to go to popularize online shopping in rural China.''_______________________________________________________________________________ _______________________________________________________________________________ _______________________________________________________________________________ ___________________________________________________________________2.阅读下面短文，根据其内容写一篇60词左右的内容概要。

阅读理解When you think of Arcitc答案When you think of the Arctic（北极）,you imagine an icy land of pure white snow.Others imagine it as the last reall y clean place left on Earth.We have polluted the deepest oc eans with plastic trash,and now,CNN sys,"It's the Arctic's turn."German scientists have recently found micro plastics（微塑料）in Arctic snow,the Associated Press reported.Micro pl astics are pieces of plastic smaller than 5 millimeter.Sadl y,the scientists found 1,800 pieces of micro plastic per li ter of snow.How is plastic pollution reaching the Arctic?According to scientists,"It's obvious that the majority of the micro plastic in the snow comes from the air."They fall off of pl astic objects and are moved by the wind,just like dust.They mix with ice in the air and fall to the ground as snow.Fin ding these plastics in Arctic snow means that we may breath e them in.An even higher amount of micro plastic was found in the snow around cites.Are they bad for us?Scientists cannot answer this quest ion for now,according to the World Health Organization.We d o know that our bodies cannot take in"large"pieces of microplastics.However,if the plastics are small enough,they can find ways into our bodies and stay there for a long time,w hich can be bad for our health.What's more,earlier studies have shown that micro plastics may contribute to lung cance r risk.Micro plastics have also been found in rivers and ocean s around the world.Previous research has found that they fl ow over long distances and into our oceans,damaging ecosyst ems（生态系统）along the way.They start in our waste water, when we wash clothes with plastic fibers.The waste water th en flows into rivers and out to sea,where they are eaten by sea animals.If people then eat these animals,it means that we're eating them as well.(1)According to the first two paragraphs,what happened to the Arctic?A.It became the last clean place on Earth.B.Much plastic trash was left for pick-up.C.It has already been polluted by micro plastics.D.1,800 pieces of micro plastic were found there.(2)What's the main idea of Paragraph 3?A.What is the Arctic snow like?B.How dangerous the micro plastics are!C.Where does the micro plastic come from?D.How to cut down on micro plastics in the Arctic?(3)What does the last paragraph tell us?A.We can't wash clothes with plastic fibers.B.Sea animals are in danger because of micro plastics.C.Micro plastics are mainly found in rivers and oceans.D.Micro plastics can be bad for the environment and our health.(4)Where can we probably find the passage?A.In a magazine.B.In a storybook.C.In an advertisement.D.In a guide book.【解答】(1)C(2)C(3)D(4)A【分析】(1)文章大意：本文主要介绍了北极已经被微塑料污染以及这种污染给环境和人类生活带来的影响。

塑料袋不能分解英语作文Plastic bags are a big problem. They are everywhere and they never go away. They can last for hundreds of years in the environment, causing harm to animals and polluting our oceans and land.The problem with plastic bags is that they are not biodegradable. This means that they do not break down naturally over time like other materials. Instead, theyjust break into smaller and smaller pieces, which can be harmful to animals if they ingest them.When plastic bags end up in the ocean, they can be mistaken for food by marine animals. This can lead to the animals getting sick or even dying because of the plasticin their stomachs. It's a big problem for the health of our oceans and the creatures that live in them.Plastic bags also contribute to the pollution of our land. They can be found littered everywhere, from citystreets to rural areas. This not only makes our environment look dirty and unattractive, but it also poses a threat to wildlife that may become entangled in the bags or mistake them for food.One of the biggest issues with plastic bags is that they are used for such a short amount of time before being thrown away. Many people use plastic bags just once or twice before disposing of them, which means that a huge amount of waste is created in a very short period of time.In conclusion, the problem with plastic bags is clear. They are a major source of pollution and harm to our environment. It's important for us to find alternatives to plastic bags and to reduce our use of them as much as possible.。

That was what the picture on Jake Smith's bedroom wall said. Jake liked having a picture that said something important, and that showed he cared. He just never expected to get a chance to save a real whale, one right in his own neighborhood.It was a Saturday morning when the newspaper first reported the whales' coming.A group of the animals were swimming close to the beach in Jake's hometown. All the local people rushed out to the beach to see them. They were expecting a beautiful show, better than a movie.Then one whale swam in the direction, directly towards land. It came with the waves(海浪), and when the waves left, its huge body was on the sand. Suddenly, Jake and his family and all the others were no longer sightseers. They had to become rescuers(救援者). A few people ran towards the animal. They pushed and tried to force the whale back into the water, but it was no use.An animal rescue team soon arrived in a truck with heavy lifting machinery, to help move the animal. Jake and his family couldn't do much on the beach, so they went back to their house and made sandwiches and hot tea for the rescuers. At least, Jake thought, they could help in some way.Back to the beach, they offered the food to the rescuers and were happy to see that it was needed. It was getting dark. Some people lined up their cars along the beach and shone the headlights on the sand. The rescuers would not give up. After trying many times they were finally able to lift the whale into the water. Everyone cheered when it headed out to the sea. It swam out about a mile and then disappeared for a moment under the sea. Then, in what looked like a jump of joy, it rose high above the water — a thank-you to those who had worked so hard to save its life.1. What does the picture on Jake's wall tell us about him?A.He lived near the ocean.B.He cared about the environment.C.He worked as an animal rescuer.D.He thought whales were the most beautiful animals.2. Why did the local people go down to the beach that morning?A.To swim with the animals.B.To help rescue the animals.C.To see the animals swimming.D.To watch a movie about animals.3. Jake and his family helped save the whale .A.by calling the rescue teamB.by asking their neighbors for helpC.by giving the rescuers food and drinkD.by controlling the people on the beach4. Who played the biggest role during the rescue?A.The Smiths.B.Jake's neighbors.C.The movie makers.D.The rescue team.5. Which of the following can be the best title of the passage?A.A Whale ShowB.Save the WhalesC.Jake's DreamD.The Whales' ComingB[2018重庆A卷改编]Scientists in Britain and the United States have made a new kind of enzyme(酵素)that eats plastics(塑料). With its help, plastics can be turned into smaller parts and go away quickly. Scientists believe that, in the future, it could solve the problem of plastic pollution.The enzyme is able to break down PET, a form of plastic. PET was first made in the 1940s and is now widely used to make plastic bottles. It can remain in the environment for many years and pollute large areas of land and water. So it has always been a headache to deal with the waste from PET and other plastics.The researchers made the discovery(发现)while examining the structure of a natural enzyme in Japan. They found that the natural enzyme was helping to break down PET plastics. So, they decided to make small changes to the enzyme by adding some amino acids(氨基酸). It made the natural enzyme's plastic-eating abilities work faster and better.John McGeehan, one of the lead researchers, said, "We've made an improved enzyme. It's better than the natural one. And we are trying to make more improvements to it." He went on, "The enzyme is not harmful to humans or animals, and it is friendly to the environment. So we are considering putting it into wider use."The team is now trying to make the enzyme break down PET in large quantities(大量地). "We'll see that the plastic pollution may be stopped with this technology. However, there is still a long way to go," John McGeehan added.6.According to the scientists, the enzyme may solve the problem ofpollution.A. airB. waterC. lightD. plastic7.The underlined phrase "break down" in the passage probably means " " in Chinese.A. 实验B. 生产C. 发明D. 分解8.Researchers discovered that a natural enzyme helped eat plastics .A. in BritainB. in the USC. in JapanD. in ChinaⅣ.书面表达时光精灵带走了三年相伴的岁月,却给我们留下了满满的收获。

备战 2021 高考英语原汁原味外刊热点话题阅读特辑day9: The Marine plastic problem is bound to get worse海洋塑料问题注定会越来越严重课前导读： 《科学》杂志上发表的一项新研究表明，流入世界海洋的塑料数量将急剧上升，对于这一趋势，那些试图减少塑料垃圾的努力将无济于事。

精彩英文 The annual inflow of plastic could nearly triple from 2016 to 2040, the study found, and even if companies and governments meet all their commitments to tackle plastic waste, it would reduce the projection for 2040 by only 7%, still a more-than twofold increase in volume. The study’s authors, the nonprofit Pew Charitable Trust and sustainability consulting firm Systemiq Ltd., set out a range of measures to stem the flow and called on businesses and governments to do more to reduce the use of plastic. They developed what they say is a first-of-its-kind model of the global plastics-supply chain—from production to consumption to disposal—using data and input from 17 experts from various regions. Consumer and regulatory pressure has prompted many of the world’s biggest consumer-goods companies to commit to making all their packaging reusable, recyclable or compostable within the next five years. Businesses have also pledged to use more recycled content in their packaging, often touting suchpromises to woo shoppers. Waste-reduction advocates say those commitments aren’t enough because they focus on recycling plastic, rather than making and using less of it. Companies like Walmart Inc.,Nestle and Procter & GambleCo. say they plan to eliminate unnecessary packaging and use more refillable containers, but few have set measurable targets for doing so. 【报刊词汇预习】 1. annual 每年的 adj 2. triple 三倍的 adj. 3. inflow 流入 n. 4. commitment 承诺 n. 5. tackle 处理 vt. 6. projection 投影 n. 7. volume 体积 n. 8. twofold 双重的 adj. 9. nonprofit 非营利性 adj. 10. sustainability 持续性/səˌsteɪnəˈbɪləti/ 11. consulting 咨询的 adj. 12. stem 阻止 vt 13. a first-of-its-kind 首创的 adj. 14. plastics-supply 塑料供应的 adj. 15. disposal 处置 n 16. data 数据 n 17. input~ (into/to sth)~ (of sth)投入资源（指时间、知识、思想等）；投入；输入 vt/nHer specialist input to the discussions has been very useful. 她在这些讨论中提供的专家建议很有 助益。

Here’s our guide on how to do just that.But the next best thing is stealing away for a quick power nap when you’re dragging after lunch.[G]In a study published in Nature Neuroscience,researchers tested subjects on their perceptual performance four times throughout the day.Performance deteriorated with each test,but subjects who took a30-minute nap between tests stopped the deterioration in performance,and those who took a60-minute nap even reversed it.[H]“Naps had the same magnitude of benefits as full nights of sleep if they had a quality of nap.”said Sara Mednick,a co-author of the study and associate professor of psychology at the University of California,Riverside.[I]Dr.Mednick,a sleep researcher and the author of Take a Nap!Change Your Life,said daytime napping can have many of the benefits of overnight sleep,and different types of naps offer specific benefits.[J]For example,Dr.Mednick said a20-to60-minute nap might help with memorization and learning specific bits of information.It’s just long enough to enter stage-two sleep,or non-rapid eye movement(R.E.M.)sleep.[K]After60minutes,you start getting into R.E.M.sleep,most often associated with that deep,dreaming state we all enjoy at night R.E.M.sleep can improve creativity,perceptual processing and highly associativethinking,which allows you to make connections between disparate ideas,Dr.Mednick said.Beyond that,your best bet is a90-minute nap,which will give you a full sleep cycle.[L]Any nap,however,can help with alertness and perception and cut through the general fog that creeps in during the day,experts said.[M]So how did we even arrive at this point where aptitude is inextricably tied(紧密相连)to working long, concentrated hours?Blame technology,but think broader than smartphones and laptops;the real issue is that tech has enabled us to be available at all times.[N]“We went through a period where people were in denial and business leaders were ignoring it,”Mr. Bersin said.“They were assuming that if we give people more tools,more emails,more Slack,more chatter,and we’ll just assume they can figure out how to deal with it all.And I think they’ve woken up to the fact that this is a big problem,and it is affecting productivity,engagement,health,safety,wellness and all sorts of things.”[O]It isn’t just office workers who can benefit from an afternoon siesta(午睡).A2015study published in Current Biology looked at the at the sleeping habits of three hunter-gatherer preindustrial societies in Tanzania, Namibia and Bolivia.[P]“They’re active in the morning,then they get in the shade under the trees and have a sort of quiet time, but they’re not generally napping,”said Jerome Siegel,professor of psychiatry and biobehavioral sciences,and director of the U.C.L.A.Center for Sleep Research,a co-author of the study.“Then they do some work and go to sleep,and they sleep through the night.”[Q]Still,Mr.Siegel said,“the only genuine way to solve daytime sleepiness and fatigue starts the night before with a solid night’s sleep.”The real Holy Grail of restfulness is a regular sleep schedule with ideally seven or eight hours of sleep each night,which experts say is optimal.[R]“Daytime napping certainly does increase alertness,”Mr.Siegel said.“But it’s not as simple as going to the gas station and filling the tank.”[S]He also advises avoiding caffeine late in the day and waking around the same time every morning,even if you can’t get to sleep at the same time every night,This helps acclimate(使适应)your body to your regular wake-up time,regardless of how much sleep you got the night before.[T]So if you’ve made it this far and you’re interested in giving workday naps a try(or just starting to nod off),here’s a quick guide to the perfect nap;Find a quiet,unoccupied space where you won’t be disturbed.Try to make your area as dim as possible(or invest in a sleep mask you can keep in the office).Earplugs might help.too.Aim for around20minutes.Any longer than that and you’re likely to wake up with sleep inertia(睡眠惰性)，which will leave you even groggier(头脑昏沉的)than before.36.Participants’perceptual performance became better after sleeping one hour between tests in an article inNature Neuroscience.37.Jerome Siegel found that only by sleeping soundly through the previous night could people tackle theirweariness during the day.38.Our talent is closely bound to working with concentration for long periods of time because technologymakes us accessible24/7.39.Taking a nap at work is normally regarded as laziness that should be held in contempt and avoided inworkplace.40.Between20to60minutes,people can get into non-REM sleep which may improve memory and learningability according to Dr.Mednick.41.People can doze off at lunch and coffee breaks and defended themselves by saying their improvedproductivity and alertness when bosses investigated their whereabouts.42.The author’s tips on taking a perfect nap involve sleeping place,environment and duration.43.The author believes business leaders are aware that availability at any time due to technology has negativeeffects on every aspect of people’s life.44.The optimal length of a nap was an hour and a half so that people could go through a complete sleep cycle.45.Josh Bersin mentioned the cause of companies’big productivity problems and the solution which needsmore that just employees’efforts.Section CDirections:There are2passages in this section.Each passage is followed by some questions or unfinished statements.For each of them there are four choices marked A),B),C)and D).You should decide on the best choice and mark the corresponding letter on Answer Sheet2with a single line through the centre.Passage OneQuestions46to50are based on the following passage.Every office worker hates meetings.But it’s a strange sort of hate,similar to the hatred of Londoners for the Northern Line,or New Yorkers for tourists who walk too slowly:the dislike is real,yet if the despised thing were to vanish,it’d be like surrendering a piece of your soul.When researchers probed into why people put up with the strain that meetings place on their time and sanity, they found something-those who resent and dread meetings the moat also defend them as a“necessary evil”, sometimes with great passion.True,research suggests that meetings take up vastly more of the average manager’s time than they used to.True,done badly,they’re associated with lower levels of innovation and employee wellbeing(幸福).But that’s just office life,right?It’s not supposed to be fun.That’s why they call it work.Underlying(引起)this attitude is an assumption that’s drummed into us not just as workers but as children, parents and romantic partners;that more communication is always a good thing.So suggestions abound for(大量存在)communicating better in meetings-for example,hold them standing up,so speakers will come to the point more quickly.But even when some companies consider abolishing meetings entirely,the principle that more communication is better isn’t questioned.If anything,it’s reinforced when such firms introduce“flat”management structures,with bosses always available to everyone,plus plenty of electronic distraction.In fact,constant connectivity is disastrous for both job satisfaction and the bottom line.And anyway,once you give it three seconds’thought,isn’t it cleat that more communication frequently isn’t a good thing?Often,the difference between a successful marriage and a second-rate one consists of leaving about three or four things a day unsaid.At work,it’s surely many more than four,though for a different reason;office communication comes at the cost of precisely the kind of focus that’s essential to good work.Yet we’re so accustomed to seeing talking as a source of solutions-for resolving conflicts or finding new ideas-that it’s hard to see when it is the problem.46.What does the author say about meetings?A)Londoners hate them as well as the Northern Line.B)They can help to keep workers’physical and spiritual health.C)Workers might be reluctant to give up them completely.D)New Yorkers dislike meetings more than Londoners.47.What did researchers find about people’s attitude towards meeting?A.Their attitude and behavior are paradoxical.B)People who hate meetings the most are senior insane.C)Those who like meetings might be considered insane.D)More meetings are regarded as a sign of less innovation.48.Why do people think that more communication is always a good thing?A)Because the concept is firmly believed by workers.B)Because everyone loves to communicate with others.C)Because the idea has been instilled into people’s mind.D)Because communication is vital for building relationships.49.What does the author think of the“flat”management structure?A)It forces bosses to frequently contact their employees.B)It helps to soften employees’bottom line of work.C)It is definitely a disaster to employees’job satisfaction.D)It strengthens people’s deeply-rooted notion of communication.50.What is the author’s argument about office communication?A)It is an effective way to solve office conflicts.B)It affects work efficiency in a negative way.C)It should come to a halt at intervals.D)It is useful for workers to find new ideas.Passage TwoQuestions51to55are based on the following passage.The Internet has enabled the spread of information at lightning speed.This information revolution has created tremendous business opportunities for online publishers,but not all of them maintain proper quality-control mechanisms to ensure that only good information is being shared.Instead,many publishers aim simply to make money by whatever means possible,with no regard for the implications for society at large.When selfish publishers set up shops online,the primary goal is to publish as much as possible,often at the cost of quality.In this respect,many publishers start numerous online journals focused on overlapping(重叠的)disciplines—to increase their total number of published papers—and hire young business managers who do not have any experience in either science or publishing.In some cases,online publishers even give up peer review, while still presenting themselves as scientific journals—deception designed to take advantage of scientists who simply want to share their research.If publishers structure their business to make more revenue,it often does harm to their products.When publishers start journals with overlapping domains,in combination with the pressure to publish more studies,this could promote the publication of marginal or even questionable articles.Moreover,publishers with multiple overlapping journals and journals with very narrow specialties(专业)increase the demands on the time and efforts of willing reviewers.With the fact that reviewers are generally not compensated for their time and effort,journal editors are often unable to find enough reviewers to keep up with the increased publication rate.To improve the situation and increase the trust in scientific community,the pressure to publish must be reduced.Funding and promotion decisions should not be based on the number of publications,but on the quality of those publications and a researcher’s long-term productivity and instructions.And that’s just the start.We need additional mechanisms,such as Beall’s list of predatory(掠夺的)publishers, to alert scientists to fake journals and fake articles.In addition,the price for online publication must be controlled and a mechanism must be put in place to honor and reward hard-working reviewers.51.What does the author think of online publishers?A)A small proportion of them can guarantee their publishing quality.B)They have lots of opportunities to renovate their business models.C)Many of them tend to try every means to make a buck.D)Social impact is their first priority when publishing books.52.It can be inferred from the second paragraph that______.A)peer review generally is a criterion to identify academic journalsB)researchers focus their research on the combination of disciplinesC)scientists care about their publications rather than researchD)young business managers are willing to face new challenges53.Why can’t publishers find enough reviewers to review papers?A)Reviewers are pressed for time when reviewing articles.B)Reviewers’gains can’t make up for what they have done.C)Publishers may compel reviewers to accept marginal articles.D)Publishers urge reviewers to increase publication rate rapidly.54.What is the author’s suggestion for online publication?A)More weight should be put on the quantity of publications.B)It is worthwhile to reward diligent reviewers for their effort.C)Fake journals should be reported to a regulatory organization.D)The price of online publication should be lowered greatly.55.What is the main idea of this passage?A)Online publishers should take measures to fight against fake scientific journals.B)Online publishers are pursuing their work efficiency at the cost of quality.C)Online publishers business models are quite likely to harm their publications.D)Online publishers are sacrificing the quality of research articles to make money.PartⅣTranslation(30minutes)Directions:For this part,you are allowed30minutes to translate a passage from Chinese intoEnglish.You should write

外刊精读精练地球快要变成“塑料星球”导读：气候变化仅仅是地球遇到的挑战之一，我们所居住的星球还面临着堆积如山的垃圾和废弃物，尤其是白色垃圾。

一项研究说，自1950年至今，人类已生产出83亿吨塑料制品，并尚未找到有效处理和回收塑料制品的方法。

我们能做些什么呢？一、语篇泛读Vocabulary: Environment 词汇: 环境Here’s a staggering statistic. Scientists have calculated the total amount of plastic ever made: 8.3 billion tonnes. Looked at another way, that’s as heavy as 25,000 Empire State Buildings or one billion elephants. And incredibly, almost all of it has been made in the last 65 years.So what’s the problem? Much plastic is in the form of packaging which is used just once and then thrown away. According to a major new study from the University of California, 9% of this is recyled, 12% is incinerated and 79% goes to landfill. And because most plastic doesn’t biodegrade, once it’s in the ground, it stays there.It’s a situation that has led the paper’s lead author,ecologist Dr Roland Geyer, to say that we are “rapidly heading towards ‘Planet Plastic'”. He believes that there’s already enough waste out there to cover the whole of Argentina.The team behind this report also estimate that eight million tonnes of plastic waste are escaping into the sea every year. This has generated concern that plastic is entering the food chain, though fish and other sea life which ingest the smaller fragments.Of course, the reason why there’s so much plastic around is that it’s an amazingly useful material. We can’t get enough of it. It’s durable and adaptable, and is used for everything from yoghurt pots to spaceships. But it’s precisely this quality which makes it a problem. The only way to destroy plastic is to heat or burn it – although this has the side effect of harmful emissions.So what’s the alternative, other than using less plastic? Oceanographer Dr Erik van Sebille from Utrecht University says we’re facing a “tsunami” of plastic waste, and that the global waste industry needs to “get its act together”.Professor Richard Thompson, a marine biologist from Plymouth University, say s it’s poor design that’s at fault. He says that if products are currently designed “with recyclability in mind”, they could be recyled around 20 times over.Dr Geyer agrees: “The holy grail of recycling is to keep material in use and in the loop forever if you can. But it turns out in our study that actually 90% of that material that did get recycled - which I think we calculated was 600 million tonnes - only got recycled once.”二、词汇表staggering 令人震惊的packaging 包装材料incinerate 被焚毁的landfill 垃圾填埋场biodegrade 生物降解ecologist 生态学家food chain 食物链ingest 咽下（食物）fragment 碎片，碎块durable 耐用的adaptable 适应性强的emission 排放物oceanographer 海洋学家tsunami 海啸get your act together合理安排，有条理地筹划marine biologist 海洋生物学家at fault 有责任，有过错recyclability可再利用性loop 循环turn out 结果是（尤指出乎意料的结果）三、测试与练习阅读课文并回答问题。
