A 教材同步单元练习 一、阅读理解 Passage 1 The scale of the climate crisis is now undeniable.Global temperatures are rising,extreme weather events are becoming more frequent,and ecosystems are under unprecedented stress.While the scientific community has been sounding the alarm for decades,the gap between awareness and meaningful action remains vast.A key point of contention lies in the debate between individual action and systemic change On one hand,proponents of lifestyle changes argue that millions of people adopting plant-based diets, giving up air travel,or living car-free can collectively drive demand and create a cultural shift.These actions,they claim,are not just symbolic but can reduce an individual's carbon footprint by up to 25%. However,critics contend that this places an unfair burden on individuals while letting corporations and govemments off the hook.They point to a 2017 study by the Carbon Majors Database,which found that just 100 companies have been responsible for over 70%of global greenhouse gas emissions since 1988. From this perspective,focusing on individual choices like changing a light bulb is a dangerous distraction The real solution,they argue,lies in large-scale policy interventions,such as a carbon tax,massive investment in renewable energy infrastructure,and strict regulations on industial pollution.Without these systemic changes,the efforts of individual activists,however well-intentioned,will be like tying to empty the ocean with a teaspoon. The tuth,perhaps,is not an either-or proposition but a both-and one.A sustainable future demands a two- pronged approach.Individual actions are powerful because they build social momentum,demonstrate that change is possible,and make it harder for policymakers to ignore the issue.They can create the political will necessary for systemic change.Meanwhile,systemic changes are essential to make sustainable choices easy,affordable,and accessible for everyone.A well-designed carbon tax,for instance,makes a plant-based meal cheaper than a steak,automatically shifting consumption patterns without requiring every person to be a committed environmentalist.Ultimately,collective action and personal responsibility are not in competition;they are two sides of the same coin,each reinforcing the other in the urgent fight to save our planet. ()1.What is the main argument of the passage? A.Individual lifestyle changes are more effective than government policies. B.Systemic changes are the only solution to the climate crisis. C.Both individual and systemic actions are necessary and complementary. D.The climate crisis is too large for any single type of action to address. ()2.The phrase "letting corporations and governments off the hook"in paragraph 2 most likely means A.allowing them to escape responsibility B.praising them for their efforts C.forcing them to take action D.criticizing them for their inaction ()3.Why do critics argue that focusing on individual actions is a"dangerous distraction'? A.Because such actions are too expensive for most people B.Because it shifts attention away from the major polluters. C.Because individual actions have no impact on the environment. D.Because it discourages people from participating in protests ()4.What does the author suggest is the role of individual actions in achieving systemic change? A.They are a substitute for effective policies. B.They help to build public support and political will. C.They are only symbolic and have little real-world effect. D.They are the most direct and efficient way to reduce emissions. ()5.Which of the following best describes the author's attitude in the last paragraph? A.Pessimistic and skeptical. B.Critical and one-sided C.Balanced and constructive. D.Indifferent and neutral. Passage 2 It is a well-established fact that biodiversity loss is accelerating at an alarming rate,with species extinction happening up to 1,000 times faster than the natural background rate.A lesser-explored,yet equally critical,dimension of this crisis is the profound impact it has on the emergence and spread of infectious diseases.The connection between a healthy ecosystem and human health is far more direct and consequential than many realize.When we destroy natural habitats,we are not just losing charismatic animals like tigers or pandas;we are dismantling the very systems that protect us from pathogens. Deforestation,for example,forces wildlife into closer contact with human populations.As forests are cleared for agriculture or ubanization,animals like bats,rodents,and primates lose their homes and are forced to seek food and shelter in human-dominated landscapes.This increases the probability of "spillover"events,where a pathogen that normally circulates among wild animals jumps to humans. Research has shown a clear correlation between deforestation rates in West Afiica and the emergence of the Ebola virus.Similarly,the fragmentation of habitats can stress animal populations,making them more susceptible to disease and increasing the viral load they carry. Furthermore,the loss of biodiversity itself can act as a buffer against disease spread.This is known as the "dilution effect."In a highly diverse ecosystem,many potential host species exist,but they vary in their ability to transmit a pathogen.When biodiversity is high,a disease-canying tick or mosquito is more likely to encounter a"dead-end host"an animal that cannot pass the disease on-thus reducing the probability of an outbreak.Conversely,in a simplified ecosystem dominated by a single species (like a farm or a monoculture forest),that species is often a highly competent host,creating a "reservoir"for the disease.The loss of the passenger pigeon in North America,for instance,is believed to have removed a crucial dilution host for Lyme disease,potentially contributing to its current prevalence Protecting and restoring ecosystems,therefore,is not a luxury or a separate concem from public health;it is a fundamental,cost-effective strategy for preventing future pandemics.Investing in the conservation of tropical forests and wetlands is an investment in a global health insurance policy.By safeguarding biodiversity,we are not simply saving species;we are fortifying the natural bariers that keep our own species safe.The health of our planet and the health of its people are inextricably linked,and we ignore this connection at our peril. ()1.What is the primary focus of the passage? A.To list the main causes of biodiversity loss. B.To explain the link between ecosystem health and disease nisk. C.To compare the effectiveness of different conservation strategies. D.To argue for more funding for medical research. ()2.According to the passage,how does deforestation contribute to infectious disease outbreaks? A.By creating new breeding grounds for mosquitoes. B.By directly producing new pathogens. C.By increasing the contact between humans and wildlife. D.By reducing the population of dead-end hosts. ()3.The "dilution effect"refers to the phenomenon where A.high biodiversity reduces the risk of disease transmission B.environmental pollution weakens virus strength C.human activities directly kill most pathogens D.animals become immune after being exposed to a virus ()4.What is the role ofa "dead-end host"in an ecosystem? A.It is the primary canier and spreader of a disease. B.It cannot transmit a disease further after being infected. C.It is more resistant to disease than other species. D.It is the first animal to be infected by a new pathogen. ()5.What does the author mean by saying "investing in...conservation...is an investment in a global health insurance policy'? A.It is a cheap way to avoid expensive medical treatments. B.Protecting nature is the most effective way to prevent pandemics. C.Conservation should be funded by health insurance companies. D.Private insurance policies are not needed for pandemic protection. 二、完形填空 Many people today are aware of the need to protect the environment.However,turning this awareness into consistent action can be challenging.We may recycle our waste,but it is often difficult to resist the of a cheap,disposable product.The convenience of modern life frequently comes into with our desire to be eco-friendly. The story of a small town in Japan,Kamikatsu,provides a powerful Thirty years ago, Kamikatsu was like any other small town,burning most of its waste in incinerators.When a new law made this practice and expensive,the town had to find another way.Instead of building a more modern incinerator,the townspeople made the _decision to aim for zero waste.They committed themselves to a rigorous recycling program that now sorts waste into 45 different categories, from aluminum cans to light bulbs to cooking oil. This system requires a huge amount of from every resident.They must wash their food containers,remove labels,and take their sorted waste to the town's recycling center.At first,many residents the idea,citing the inconvenience and extra time required.It seemed like an enormous on their daily lives.But the town persisted,building a community culture around the challenge. Elderly residents,in particular,became the backbone of the system,proudly ensuring their waste was sorted correctly.They saw it not as a burden,but as a point of pride and a to their grandchildren's future. Today,Kamikatsu recycles over 80%ofits waste,a figure that far the national average.While the goal of absolute zero waste remains a target,the town's achievement is remarkable.It demonstrates that a community's collective will can significant,practical change.The challenge of living sustainably often feels overwhelming at a global level,but Kamikatsu's story reminds us that action can begin at a local scale,one household,one category of waste at a time.It shows that a to a seemingly impossible goal,backed by community effort,can yield extraordinary results.The biggest is not about technology,but about our mindset and our willingness to a more resourceful and conscientious way of living. 1.A.proof B.convenience C.demand D.advantage 2.A.line B.conflict C.touch D.agreement 3.A.example B.waming C.theory D.lesson 4.A.legal B.illegal C.necessary D.popular 5.A.easy B.disappointing C.radical D.quick 6.A.nearly B.exactly C.only D.rarely 7.A.money B.effort C.patience D.space 8.A.supported B.resisted C.welcomed D.ignored 9.A.dependence B.focus C.impression D.demand 10.A.threat B.gift C.secret D.memory 11.A.matches B.surpasses C.reflects D.influences 12.A.imagine B.accept C.achieve D.avoid 13.A.commitment B.contribution C.announcement D.requirement 14.A.problem B.barier C.benefit D.goal 15.A.create B.define C.embrace D.reject 三、阅读短文回答问题 Read the following passage and answer the questions in complete sentences. Plastic pollution is now so pervasive that it has become a symbol of the Anthropocene,the current geological age defined by human impact on the planet.Microplastics,tiny fragments less than 5mm in size,have been found everywhere:from the deepest ocean trenches to the Arctic ice,in our drinking water,and even inside the human body.Recent research has confiurmed their presence in human blood for the first time,raising urgent questions about their potential health impacts. The study,conducted by a team of scientists in the Netherlands,analyzed blood samples from 22 anonymous,healthy adult volunteers.They found plastic particles in 17 of them,nearly 80%of the participants.Half of the samples contained PET plastic,commonly used in drink bottles,while a third contained polystyrene,used for food packaging.The particles were small enough to be transported through the bloodstream and could potentially accumulate in organs. While the long-term health consequences of having plastics in our blood are still unknown,early studies on animals and cells in a laboratory setting suggest cause for concern.Some plastics are known to contain or attract harmful chemicals,such as BPA and phthalates,which can disrupt the endocrine system.There are also fears that microplastics could cause inflammation,damage cells,or cary pathogens into the body The presence of these particles in the bloodstream means they can bypass the body's natural defense systems,traveling directly to organs like the liver,kidneys,and brain. This research marks a significant step forward in our understanding of human exposure to plastics.The detection of plastics in the blood is a"wake-up call,"according to the study's authors.It underscores the need for urgent research into how these particles break down and move through the body,and what effect they have on our health.It also adds weight to calls for a global treaty to curb plastic production and pollution.The problem is not just a matter of litter on beaches,it has become a deeply personal health issue,as the plastic we throw away is finding its way back into our own bodies,completing a dangerous ecological loop. 1.According to the recent study,what percentage of the participants had plastic particles in their blood? 2.List two types of plastic mentioned in the passage that were found in the blood samples. 3.Why is the presence of plastic in the bloodstream considered more worrying than in other parts of the body?(根据文章内容回答) 4.What does the author mean by saying the research is a"wake-up call'? 5.What does the phrase "completing a dangerous ecological loop"in the last paragraph imply? 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。 Climate change is no longer a distant threat,it is a present reality.One of its most visible consequences is the rapid melting of glaciers around the world.These massive bodies of ice are shrinking at an unprecedented rate, (pose)a serious threat to billions of people who depend on them for fresh water.The water stored in glaciers acts a natural "savings account"for the dry season.As they disappear,nivers may flow strongly for a few decades,but this increased flow will soon give way a dramatic decline,leading to severe water shortages. The impact of this melting is not limited to water supply.The loss of glacial ice also contributes (direct)to rising sea levels.As glaciers melt,the water they release eventually flows into the ocean. the ice sheets of Greenland and Antarctica are the main drivers oflong-term sea-level rise,the meltwater from mountain glaciers is a significant contributor that cannot (ignore).Coastal communities around the world,especially in low-lying island nations,are already feeling the effects of the rising tides. Furthermore,the retreat of glaciers can destabilize mountain slopes.When a glacier melts,it leaves behind unstable rocks and debris,increasing the risk of landslides and glacial lake outburst floods(GLOFs) These catastrophic events can happen with little waining, (wash)away entire villages and infrastructure downstream.The 2017 flood in Uttarakhand,India,which destroyed a major hydroelectric dam,is a tragic example of such an event,which (link)to a nearby glacier's rapid melting.The evidence is clear:a warmer planet means a world with less ice,less dependable water,and more unpredictable risks.The time for meaningful action to reduce our carbon footprint is not tomorrow, today,for the glaciers are sending us a message that we cannot (afford)to misread. 2. 3. 4. 5 6. 7 8. 9. 10. 五、写作 假设你是李华，你们学校正在举办“建设绿色校园”的活动。作为学生会主席，请你用英语写 一封倡议书，向全校同学发出倡议。内容包括： 1.简述保护校园环境的意义： 2提出至少三条具体的环保建议（如节约资源、减少浪费、垃圾分类等）； 3.呼吁大家积极参与。 注意： 1.词数120-150左右： 2.可以适当增加细节，以使行文连贯： 3开头和结尾已为你写好，不计入总词数。 Dear fellow students, Our school is launching a campaign to build a green campus.As the president of the Student Union,I am writing to call on everyone to take part.
