Researchers from Carnegie Mellon University analyzed the environmental effects of producing different types of food.Their findings,published in the journal Environment Systems and Decisions,challenge the simple assumption that "plant-based equals eco-friendly."While cutting out red meat and dairy certainly helps,the study found that eating a diet rich in fiuits,vegetables,fish,and lean poultry can actually have a similar,or in some cases,a higher environmental cost than the standard American diet,which is high in sugar,fats,and refined grains. How can this be?The key lies in the concept of resource intensity."Growing many fruits and vegetables,especially those that are out of season or shipped from distant locations,requires a surprising amount of energy.For example,lettuce grown in a greenhouse in a cold climate can require more energy per calorie than producing pork.Similarly,soft drinks and sugary snacks have a relatively low environmental cost per calorie because they are made from cheap,resource-efficient crops like comn and sugar cane This doesn't mean you should abandon your efforts to eat healthily.Instead,the study emphasizes a more nuanced approach.It suggests that the most impactful dietary change is not just reducing meat,but also reducing overall food waste and focusing on eating foods that are in season and locally sourced.The researchers argue that shifting from the current average American diet to a"healthy"diet rich in fiuits and vegetables,according to USDA guidelines,could increase the environmental impact-including energy use,water use,and greenhouse gas emissions-by as much as 38 percent.This is because producing the recommended healthy"foods is often more resource-intensive than producing the processed foods that make up a large part of a less healthy diet. The take-home message is that environmentalism is complicated.Consumers are often bombarded with simple messages like "go vegan to save the planet."While reducing meat consumption is beneficial,this research highlights that thoughtful decisions about where and how our food is grown are equally important.The most sustainable diet,therefore,is likely one that is not only low in meat but also low in waste,low in processed foods,and high in seasonal,locally grown produce. ()1.What is the main finding of the study mentioned in the passage? A.A vegetarian diet is always the most eco-fiendly choice B.Plant-based diets can sometimes have a large environmental cost. C.The livestock industry has little impact on climate change. D.The standard American diet is the most sustainable. ()2.The writer uses the example oflettuce"(Paragraph 3)to illustrate that. A.lettuce is a very healthy food B.a simple assumption can be misleading C.growing lettuce is more popular than raising pigs D.greenhouse gases from lettuce are highest ()3.According to the study,what is a more effective way to reduce one's food-related environmental impact? A.Switching completely to a vegan diet. B.Eating more fish and lean poultry. C.Reducing food waste and eating local,seasonal produce. D.Following the USDA dietary guidelines precisely. ()4.What is the author's attitude towards the idea of going vegan to save the planet'? A.It is a completely valid and simple solution B.It is a harmful and misleading suggestion C.It is a good first step,but the issue is more complex D.It is the only option for environmentally conscious people Passage B Before they were celebrated as the"climate-fiiendlyalternative to plastic,paper bags were the standard Then came plastic,which was cheaper and more durable.Now,environmental concerns are bringing paper back,but a new study suggests that the sustainability of a bag isn't just about what it's made from- it's about how many times it's used. The study,conducted by the Danish Environmental Protection Agency,conducted a life-cycle assessment of different shopping bags,including plastic,paper,and cotton.The analysis considered not just the raw materials and production,but also transportation,energy consumption,and disposal methods.The results were surprising.A classic plastic carrier bag,often seen as an environmental villain,actually has a relatively low environmental footprint per bag,mainly because it is lightweight and requires little energy to produce. However,the problem with plastic is that it rarely gets a second chance.The vast majority are used once and then thrown away,where they can persist in the environment for hundreds of years.In contrast,the study found that to have a comparable overall environmental impact to the standard plastic bag,a paper bag would need to be used at least 43 times.Why so many?The production of paper bags is much more resource-intensive,requiring more energy and water,and the process often creates more air and water pollution.Furthermore,they are heavier,meaning more fuel is needed for transport. The findings for cotton bags are even more striking.To match the environmental cost of a single plastic bag,a conventional cotton bag would need to be used an astonishing 7,100 times.This is because growing conventional cotton is very water-intensive and often involves the use of pesticides.Even an organic cotton bag,which avoids these chemicals,would need to be used 20,000 times to have a lower global warming impact than a plastic bag.This is primarily because organic cotton yields are lower, requiring more land and water per bag produced. So,what is the most eco-fiendly bag?The answer,according to the research,is not a specific material, but a behavior:reuse.The study demonstrates that the worst bag for the environment is not the one made of plastic or paper,but the one that is used only once.A plastic bag reused as a bin liner or for other purposes significantly lowers its impact per use.The most effective strategy is to use any bag you have as many times as possible.The real villain is our throwaway culture,not the bag itself.The most sustainable choice,therefore,is to choose a bag you can and will reuse many,many times,and to keep using it until it falls apart. ()5.What can we learn from the Danish study? A.Paper bags are always a better choice than plastic bags. B.Cotton bags are the most eco-fiiendly option C.The number of times a bag is used is crucial to its environmental impact. D.All types of bags have an equal environmental footprint. ()6.According to the passage,what is the main environmental problem with plastic bags? A.Their production process is very energy-intensive. B.They are too light and difficult to recycle C.Their single-use nature leads to long-term pollution. D.They are more expensive to produce than paper bags ()7.The word "striking"(Paragraph 4)is closest in meaning to. A.interesting B.impressive C.disappointing D.violent ()8.What is the author's main purpose in writing this passage? A.To criticize the use of plastic bags B.To promote the use of cotton bags. C.To argue against the throwaway culture. D.To compare the production costs of different bags 二、完形填空 In the heart of the Pacific Ocean lies an area known as the Great Pacific Garbage Patch.It is not a solid island of trash,but a huge 1. of tiny plastic debris floating just below the surface.Marine animals often mistake this plastic for food.A sea turtle may see a floating plastic bag and think it's a jellyfish.When a bird 2 a brightly colored piece of plastic,it might take it back to its chick. This leads to a slow and painful 3. for countless animals,as their stomachs become filled with indigestible waste. The problem seems 4. The patch is estimated to be twice the size ofTexas and contains 1.8 trillion pieces of plastic.How can we possibly clean it up?One young Dutch inventor named Boyan Slat was not discouraged.At the age of 16,while on a diving trip in Greece,he was appalled to see more plastic bags than fish.He 5. to find a solution.His idea was not to chase the plastic with boats and nets,which would be slow and costly.6. he proposed a system of floating barriers that would use the ocean's natural currents to gather the plastic. His concept,known as The Ocean Cleanup,faced huge 7. Many experts said it would never work.They argued that the barriers would break or that the plastic was too small to collect.However,Slat and his team 8. After years of testing and several failed prototypes,they launched a 600-meter- long floating tube in the Pacific in 2018.The system works like a giant,slow-moving"skimmer."It uses the currents to bring the plastic to it,where it is then collected and brought back to land for 9. While the technology is promising,it is not a 10. The most effective way to deal with the problem is to stop the plastic from 11. the ocean in the first place.This requires a massive change in our 12 We have to move away from our "take-make-dispose"culture towards a "circular economy"where materials are 13. and reused.Companies need to design products that are easier to recycle,and individuals need to be more 14. about their consumption.The Ocean Cleanup is a brilliant and necessary tool,but it's a"band-aid"for a wound that needs a much deeper,systemic 15. 1.A.island B.mass C.collection D.group 2.A.finds B.eats C.sees D.notices 3.A.death B.life C.process D.journey 4.A.simple B.easy C.impossible D.effective 5.A.decided B.refused C.failed D.pretended 6.A.However B.Therefore C.Instead D.Besides 7.A.support B.approval C.doubt D.funding 8.A.gave up B.carried on C.turned back D.set out 9.A.recycling B.storage C.dumping D.fishing 10.A.cure-all B.waste of time C.piece of cake D.hard job 11.A.protecting B.polluting C.entering D.destroying 12.A.lifestyle B.environment C.technology D.habits 13.A.consumed B.produced C.reused D.designed 14.A.careful B.worried C.curious D.forgetful 15.A.problem B.change C.problem D.plan 三、阅读短文回答问题 Read the following passage and answer the questions in complete sentences.(每题答案不超过l2个词) The world's first floating dairy farm has opened in the port of Rotterdam in the Netherlands.This innovative project is the idea of businessman Peter van Wingerden.He was inspired after seeing the havoc Huricane Sandy caused to food supplies in New York City in 2012.He thought,"Why not bring food production closer to city consumers?" The farm,named "Floating Farm,"is a three-story structure on the sea.It houses about 40 cows.The cows live in a comfortable,self-sustaining environment on the top floor,where they have soft rubber flooring,automatic brushes to scratch themselves,and a robotic milking system.The farm aims to produce fresh,local milk,yogurt,and cheese for the city of Rotterdam. The farm is designed to be sustainable in several ways.Firstly,the cows are fed on waste products from the city.Their feed includes grass clippings from local parks and sports fields,and even leftover grains from local breweries.This reduces food waste and the need to import animal feed from abroad.Secondly, manure from the cows is collected and processed into natural fertilizer for parks and gardens in the city. Rainwater is collected and purified for the cows to drink. While the farm is a promising step,critics point out some challenges.The cost of building such a facility is very high.Furthermore,the cows produce methane,a powerful greenhouse gas.Mr.van Wingerden acknowledges this but says the farm's closed-loop system captures some of the emissions.He believes that urban farming,including floating farms,is a necessary solution for future food security,especially as the world's population continues to grow and become more urbanized.The project aims to inspire similar farms in other cities around the world. 1.What inspired Peter van Wingerden to create the floating dairy farm? 2.Where is the Floating Farm located? 3.What are the cows on the farm fed on? 4.What is a negative aspect of the floating farm mentioned in the passage? 5.According to the passage,what is one major challenge for urban farming projects like this? 四、短文填空（词汇运用） 阅读下面短文，在空白处填入1个适当的单词或括号内单词的正确形式。 Our planet is facing a climate crisis,and the need for action has never been more urgent.Many countries are now working towards 1. (achieve)net-zero carbon emissions.This ambitious goal requires a complete transformation of our energy systems and a move away from fossil fuels.A key part of this strategy is the 2.(adopt)ofrenewable energy sources like wind and solar power.
