The power of citizen science lies in its scale.Professional scientists,despite their expertise,are limited in numbers and resources.They cannot be everywhere at once.However,with the help of thousands of volunteers armed with smartphones and simple kits,data collection can occur across vast geographical areas and over long periods.For example,projects like the "Great Backyard Bird Count"rely on birdwatchers worldwide to count species in their local areas.The data collected helps scientists track migration patterns and population changes,providing early wamnings about biodiversity loss.Similarly,apps like "iNaturalist"allow users to upload photos of plants and animals,instantly identifying species and contributing to a global database of life on Earth. However,the impact of citizen science goes beyond just gathering data.It serves as a powerful educational tool,fostering a deeper connection between people and their environment.When a family monitors the health of a local stream or a class tracks the blooming of flowers in spring,they are not just collecting numbers.They are actively observing,questioning,and leamning about ecological processes.This hands-on experience often transforms passive awareness into active stewardship Individuals who participate in citizen science projects are more likely to adopt pro-environmental behaviors,such as reducing pesticide use or advocating for local habitat protection.In this sense,the real contribution of citizen science might not be the data itself,but the creation of a more scientifically literate and environmentally engaged public. Nevertheless,challenges remain.Concerns about data quality are common,as volunteers may lack the rigorous training of professionals.To address this,many projects incorporate built-in verification systems,where expert reviewers confirm the accuracy of submissions.Furthermore,the sustainability of such projects often depends on funding and the long-term commitment of participants.Despite these hurdles,the potential of citizen science to drive both scientific discovery and environmental action is immense.It democratizes research,placing the tools for understanding our world into the hands of everyone.As a global community,hamessing the collective power of citizen scientists may be one of our most promising strategies for addressing the environmental challenges that lie ahead. ()1.What is the primary purpose of the first paragraph? A.To criticize the lack of grand policy changes. B.To introduce the concept of citizen science. C.To highlight the urgency of environmental problems. D.To compare professional scientists with ordinary people. ()2.According to the passage,what is a key advantage of citizen science? A.It ensures higher quality data than professional research. B.It allows for large-scale data collection that professionals cannot achieve alone. C.It is the only way to track bird migration patters. D.It is a cheaper altemative to govemment-funded research. ()3.The author uses the example of "iNaturalist"primarily to illustrate. A.how technology makes data verification easier B.how citizens can contribute to a global database C.the difficulty of identifying different species D.the popularity of smartphone apps among teenagers ()4.What does the phrase "active stewardship"in paragraph 3 most probably mean? A.The ability to manage one's own finances. B.A formal job position in environmental agencies. C.The responsible management and protection of the environment. D.A feeling of anger towards environmental destruction. ()5.What challenge does the passage admit citizen science still faces? A.A lack of interest from the general public. B.The high cost of equipment for volunteers. C.Doubts about the accuracy of the data collected. D.Opposition from professional scientific organizations. Passage B The familiar image of a sea turtle entangled in a plastic six-pack ring has become a powerful symbol of the pollution crisis in our oceans.While campaigns to reduce plastic use,particularly single-use plastics,have gained significant momentum,we must confront an uncomfortable truth:for the plastic already choking our marine ecosystems,reduction alone is not a solution.We need to talk about removal.This is where the relatively young and controversial field of ocean cleanup comes into play, presenting a suite of ambitious,and often risky,technological interventions. One of the most high-profile efforts is led by The Ocean Cleanup,a non-profit organization.Their strategy involves deploying long,U-shaped floating baniers that drift with ocean currents,passively concentrating plastic debris.A support vessel then retrieves the collected waste.Proponents argue that this method is scalable and,unlike net-based systems,poses less risk to marine life because the barrier moves slowly.However,critics point to significant operational difficulties.The system has faced repeated mechanical failures,and there are concerns about its efficiency,with some studies suggesting it collects only a small fiaction of the plastic while potentially acting as an artificial reef that attracts and harms wildlife.Furthermore,the energy and resources required to manufacture and maintain these systems raise questions about their overall environmental footprint. Another promising approach involves smaller-scale,more targeted cleanups.This includes technologies like "Mr.Trash Wheel,"a solar-and water-powered trash interceptor deployed in Baltimore's harbor,which has successfully removed millions of pounds of garbage from waterways before it reaches the open ocean.Similarly,groups like Ocean Voyages Institute have organized large-scale expeditions using satellite-tracked drifters to locate and clean up massive "ghost nets"-abandoned fishing gear that continues to trap and kill marine animals.These methods are often praised for their proven effectiveness and lower risk of unintended ecological damage compared to large-scale booms, but they are slower and require significant manual labor. The debate between these two schools of thought-large-scale technological solutions versus targeted, smaller-scale efforts-highlights a fundamental tension in conservation.Investing heavily in cleanup technologies can sometimes distract from the more critical and cost-effective goal of preventing plastic from entering the ocean in the first place.Many environmentalists argue that funds would be better spent on improving waste management infrastructure in developing countries,banning problematic plastics,and innovating in the field of biodegradable materials.While cleanup is necessary to address the legacy pollution already in our oceans,it should not be seen as a silver bullet.The ultimate goal must remain a circular economy where waste is designed out of the system,preventing the problem at its source.Only by combining aggressive prevention with thoughtful,efficient cleanup can we hope to restore the health of our oceans. ()1.What is the main argument of the first paragraph? A.Reducing plastic use is the only solution to ocean pollution. B.Removing existing plastic from oceans is an urgent but complex task. C.The image of a sea turtle is an ineffective symbol of pollution. D.The field of ocean cleanup is not yet developed. ()2.What is a major criticism of The Ocean Cleanup's banier system? A.It is too expensive to manufacture. B.It moves too quickly,endangering marine life C.Its efficiency is questionable and it may have negative ecological effects. D.It is only effective in small,enclosed areas like harbors. ()3.How does the "Mr.Trash Wheel"approach differ from The Ocean Cleanup's approach? A.It is a large-scale,passive technology. B.It is a smaller-scale,targeted system that prevents waste from reaching the open ocean. C.It relies on satellite technology to locate trash. D.It focuses on removing abandoned fishing nets. ()4.The phrase "silver bullet"in the last paragraph is used to describe. A.a simple and magical solution to a complicated problem B.a very expensive technological device C.a controversial idea that has no support D.a well-planned strategy that is guaranteed to work ()5.What is the author's overall opinion on ocean cleanup technologies? A.They are a waste of money and should be abandoned. B.They are the most promising solution to ocean pollution. C.They are necessary but should be paired with stronger prevention efforts. D.They are too risky and should only be used in emergencies. 二、完形填空 Since I was a child,I have been fascinated by the ocean.Summer vacations were spent collecting shells and marveling at the 1. of life in the tide pools.So,when I joined a volunteer program for a coastal clean-up,I thought I was prepared for what I would see.I was wrong.The reality of the plastic pollution crisis is far more 2. than any documentary or news report can capture. Walking along a seemingly beautiful beach,the first few steps were deceptive.But as I looked closer the sand was 3. with tiny,colorful fragments of plastic.Microplastics,I leamned they were called.They were everywhere,mixed in with the natural sand and seaweed.It felt 4. to try and clean them up,like tying to collect grains of rice scattered on a football field.My task was to focus on the larger items:bottle caps,lighters,straws,and pieces of fishing nets.Each piece I picked up was a small victory,but the sheer 5. of the waste was overwhelming. Later that day,a local marine biologist spoke to us.He explained that many of these plastics don't 6. They just break down into smaller and smaller pieces,which are then mistaken for food by sea birds,turtles,and fish.This is where the 7. comes full circle.The toxins from the plastics enter the food chain,and eventually,they can end up on our dinner plates.Learning this,I felt a sense of 8. It was no longer just an environmental issue;it was a human health issue. The experience was a wake-up call.I 9. that picking up trash,while helpful,is a temporary fix.The real battle is about changing our habits.I started by refusing single-use plastics,canying a reusable water bottle and shopping bag.I also began a campaign at my school to install a water refill station to 10. the use of plastic bottles.It feels small,but it's a start.The ocean is in trouble,and while I can't solve the entire problem alone,I have decided to be part of the solution,not part of the pollution. 1.A.danger B.diversity C.shortage D.mystery 2.A.beautiful B.distant C.shocking D.interesting 3.A.covered B.compared C.filled D.littered 4.A.exciting B.hopeful C.foolish D.easy 5.A.size B.volume C.value D.variety 6.A.float B.disappear C.recycle D.degrade 7.A.circle B.story C.project D.journey 8.A.pride B.boredom C.urgency D.confusion 9.A.doubted B.realized C.regretted D.pretended 10.A.promote B.discourage C.require D.monitor 三、阅读短文回答问题 Read the following passage and answer the questions in complete sentences. The term "eco-anxiety"has entered our vocabulary to describe a chronic fear of environmental doom.For many,especially the younger generation,reading news headlines about melting ice caps, mass extinction,and lising sea levels can lead to feelings of helplessness,stress,and despair.This psychological burden is a very real side effect of the climate crisis.However,mental health professionals and environmental activists are now exploring ways to transform this anxiety from a paralyzing force into a catalyst for positive action.They argue that eco-anxiety is not a pathology but a rational response to a real threat;the key is how we manage it. One effective strategy is to focus on community action.When individuals join forces with like-minded people,the feeling of being alone against a massive problem diminishes.Taking part in a local tree planting event,a community garden project,or a citizen science initiative like monitoring air quality can provide a sense of purpose and collective efficacy.Seeing tangible results from one's efforts,such as a cleaned-up park or a new batch of seedlings,can significantly boost one's mood and sense of agency Another crucial step is to disconnect from the "doom-scrolling"cycle.Constant exposure to negative news,often amplified by social media algorithms,can fuel anxiety.Setting boundaries for news intake and choosing to focus on actionable information-such as how to reduce your carbon footprint or support sustainable businesses-can be more empowering.It is about shifting from being a passive consumer of bad news to an active participant in creating solutions. Furthermore,simply acknowledging and accepting the feeling of anxiety is important.Suppressing these emotions can be counterproductive.Talking about your fears with fiends,family,or a therapist can help nommalize the experience and alleviate its intensity.Many find solace in nature itself,spending time outdoors,whether it's a walk in the woods or simply tending to a houseplant,can be a powerful antidote to the abstract dread of a global crisis.By reconnecting with the beauty and resilience of the natural world,we can find the motivation to protect it,fostering a sense of "solastalgia"-the pain of losing a loved environment-into a force for healing. 1.What is "eco-anxiety"as defined in the passage? 2.According to the passage,why is community action an effective strategy against eco-anxiety? 3.What does the phrase "doom-scrolling"most likely refer to? 4.Besides community action and limiting news intake,what other way does the passage suggest for dealing with eco-anxiety? 5.What is the author's main pupose in writing this passage? 四、短文填空 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 school has launched a new environmental 1. called "Power Down for the Planet."

There are several reasons why students are drawn to fast fashion.Firstly,it is very cheap and allows us to keep up with the latest trends without spending a lot of money.Secondly,advertising and social media constantly promote the idea that we need a new outfit for every occasion,encouraging overconsumption. To be more sustainable,I have a few suggestions.We can start by buying second-hand clothes from thrift stores,which is both affordable and eco-fiiendly.Instead of always buying new,we can swap clothes with fiends or organize "clothing exchange"events at school.Most importantly,we should rethink our buying habits and choose quality items that last longer,building a "capsule wardrobe" instead of a disposable one. I hope everyone can give it a second thought before making their next purchase. Yours sincerely, Li Hua
