2024届东北三省三校高三下学期二模联考地理答案

2024年东北三省三校高三第二次联合模拟考试地理参考答案【答案】1．D 2．B 3.A【解析】第1题，废弃沙坑利用价值低，土地价格低廉，故D正确；废弃沙坑养殖锦鲤，需额外投喂饲料，而坑内饵料并不丰富，故A错误；进行养殖主要靠人工投喂，没有增加绿色植物，对减轻水土流失作用有限，故C错误；市场分布在当地众多村屯，废弃沙坑附近人口并不多，沙坑养殖并未靠近市场，故B错误。

第2题，通过村民事务管理群集中售卖，可以扩大消费市场人群，进而形成较为稳定的销售渠道，故B正确；与提高产品质量和品牌效应无关，并没有降低销售成本，故A，C，D错误。

第3题，养殖场关闭后，投喂有机饲料现象消失，水质得以提高，故A正确；沙坑依然存在未被回填，河道威胁并未解除；区域水域面积并无变化，对局地气候影响不变；沙坑养殖并未阻断水体间的联系，故关闭后对其并未构成影响，B，C，D错误。

【答案】4．C 5．D【解析】第4题，通过材料信息可知，道路无线充电，可在车辆行驶中同时进行充电，免去了充电桩充电的相关操作，故C正确。

道路无线充电需在路面下安装相关设备，故工程量更大，投资成本有所提升，故A错误。

虽然充电时间可以与正常行驶时间重叠，但充电时间长短主要取决于充电效率，故并不一定缩短充电时间，故D错误。

电动汽车实现了低碳出行，与充电方式是有线或无线无关，故B错误。

第5题，由于无线充电道路需在路面下安装相应设备，所以目前更适合铺设在新规划建设的城区，减少拆迁、拆除原有道路等成本，故选择D。

【答案】6．D 7．C 8.B【解析】第6题，历史上的赣州城建筑用地多在西北部高地，城中东部、南部低平，有具有调蓄功能的天然水塘，故可推知其作用为蓄洪，故选D。

第7题，从材料信息可知，与外江相通的部分沟渠坡度是平常水道坡度的4倍，即向外江排水处坡度加大。

地下沟渠的主要功能为排水，由于地下沟渠常年存水，极易产生淤积，会降低其蓄水排水的效果，因此将其与外江相通的部分坡度增大，可加快排水速度，进而达到清淤的效果，故C正确，A，B ,D错误。

There are four ways to visit the Museum with your class:●Guided tour:Visit the permanent exhibition accompanied by one of our activity leaders.Duration:90minutes●Workshop+guided tour:Themed tour of the exhibition(permanent or temporary depending on the topic)and workshop in the Gym or Studio,all accompanied by an activity lender.Duration:2×45minutes●Workshop+independent visit(optional):Accompanied by an activity leader,make the most of a themed workshop and extend your Olympic experience by visiting the exhibitions independently.Duration:45minutes for the workshop,unlimited for an independent visit●Independent visit:Access to all exhibition areas except educational areas.Duration:unlimitedPractical InformationSelf-guided visitors in groups with a reservation will be given priority at the entrance.If the exhibitions are too crowded,we may not be able to give you the privilege.Safety distances between adults and students/children must be respected.RatesAll our educational programs are free of charge for those under the age of16.●Children up to the age of15:freemay well be making things harder for everyone,but there doesn’t seem to be a way out.A popular sense of being stuck in an ever so exhausting rat race where everyone loses has given rise to a new buzzword:neijuan(involution).The Chinese word,neijuan,is made up of the characters for“inside”and“rolling”,and is understood as something that spirals in on itself,a process that traps participants who know they won’t benefit from it.“From a sociological point of view,involution is unavoidable because of society’s structural shifts,”said Yan Fei,a professor of sociology at Tsinghua University,“One big question for the middle class is how to remain in the middle class.Meanwhile,the lower class still hopes to change their fate.But the middle and upper classes aren’t so much looking upward,and they are marked by a deep fear of falling downward.Their greater fear is perhaps losing what they already have,”he explained.8．Why is the photo of a student in Tsinghua University mentioned in Paragraph1? A．To clarify the writing purpose.B．To present an argument.C．To introduce the topic of the passage.D．To describe a character.9．What can we learn from the passage?A．I’s common to work overtime in the real world.B．Neijuan reflects the fierce competition in China.C．Food delivery riders benefit a lot from the apps.D．People live a better life due to their great efforts.10．What can be inferred from what Yan Fei said in the last paragraph?A．The lower class suffers a deep fear of falling downward.B．The middle class tries to be a member of the upper class.C．The greatest fear of every class is to lose what they already have.D．Involution is inescapable in the development of society for each class.11．From which column of the newspaper can the passage be taken?A．Society.B．Economy.C．Entertainment.D．Tourism.Mining rare-earth(稀土)elements(REEs)has long been considered a dirty business,as it can lead to water and soil pollution,but a new technology developed by Chinese scientists may change the trend,offering a greener alternative for the industry.REEs,especially heavy ones,are an essential part of many high-tech devices,from the engines of electric cars and smartphones,to LED lights.More than90%of the global heavy KEF demand is sourced from ion-adsorption deposits(离子吸附沉积物),which form within weathering erasts(硬壳).However,conventional mining applies overmuch usage of chemical agents to recover REEs front these deposits,not only exhibiting low efficiency but also polluting the environment.Researchers from the Chinese Academy of Sciences’Guangzhou Institute of Geochemistry proposed a new approach in the journal Nature Sustainability earlier this month, showing that employing electrokinetic mining techniques to extract(提取)REEs from weathering crusts can be both clean and ing this approach,researchers generated an electric field by putting electrodes(电极)on the top and bottom of a volume of soil.The electrokinetic effect can speed up the migration of REEs,reducing the need for harmful chemical agents.To evaluate the practicality of the new method,they carried out several experiments of different scales.Results suggested that the new method outperformed traditional mining techniques.For instance,the scaled-up experiments achieved a recovery efficiency of96% within67hours by using ing the conventional technique,it was only62% at130hours.The difference between the impact of the old and the new approaches was even more significant in an on-site field test:Using electrokinetics can achieve a recovery efficiency higher than90%,an80%decrease in polluting agent usage and a70%reduction in impurity.The study confirmed that this novel electrokinetic technology enabled green,efficient and selective recovery of REEs.Researchers also noted that the new method has great potential for use in the mining of other critical metals under conditions in which the metals exist in ionic states.12．Why is the new technology referred to as a“greener alternative”for REE mining? A．It is based on cleaner energy.B．It achieves a higher recovery efficiency.C．It recovers REEs from weathering crusts.D．It depends less on the use of chemical agents.13．How does the author present the practicality of the new technology?A．By analyzing causes.B．By listing examples.C．By providing test results.D．By giving instructions. 14．What can we know about the new technology?A．It contributes to the extraction of purer REEs.B．It causes REEs to be mined at a higher cost.C．It is widely adopted in mining critical metals.D．It frees REE mining of the impact on nature.15．What is the text mainly about?A．A new technology with great potential in mining metals.B．A greener REE mining technology with higher efficiency.C．The difficulties in mining REEs from ion-adsorption deposits. D．The differences between conventional and new REE mining methods.三、未知I’m a creature of habit.The walking route I’ve established around the block in New York________varies.On my walk,I take________in what my fellow gardeners have planted.

When I say “old books”, I don’t mean classics, though. I mean books with yellow pages, broken spines (书脊) and odd wood-like smells that you need to be careful not to break because they are already so worn down and bring you severe discomfort. One can assume that I didn’t own many old books. I had merely a few here and there that my parents had gifted me, but nothing too special.In the fourth grade, I was ready to explore a new world of reading, one that went beyondthe likes of children’s chapter books and teenagers’ topics. Just then, I found my parents’ old copies of the entire Harry Potter book series. Visually, my parents’ books were my worst nightmare. I remember thinking to myself that there was no way I would be able to read these books. However, I eventually had to come to terms with the fact that if I wanted to read the series, I would have to read my parents’ copies. And so began the terrible journey of reading seven old books.When it was time for me to read the final copy, I was kind of a changed woman. I still strongly disliked old books, but the plot of the entire Harry Potter series had attracted me so much I had almost entirely forgotten what the books looked like. By the end, I had devoted the entire Harry Potter bookshelf in my room.Now, I love old books. While the covers are sometimes so worn down that you can barely read the title of the book, you can understand what it’s about anyway. After all, an old book is a representation of generations of readers who have chosen to live in a specific fictional world because the story it contains is just that good. Old books have meaning and I love how much they mean to me now.4．What can we learn about the author from the first two paragraphs?A．She felt uneasy about owning old books.B．She was on bad terms with her parents.C．She grew fondness for reading classics.D．She was often gifted old books by her parents. 5．How did the author feel when seeing her parents’ Harry Potter series in the fourth grade?A．Confused B．Scared C．Discouraged.D．Astonished. 6．What does the author mean by saying “I was kind of a changed woman” in paragraph 3?A．She started to enjoy reading fictional books.B．She began to ignore the appearance of the books.C．She accepted putting old books on her shelf.D．She figured out what she truly wanted to read.7．What is the best title of the text?A．My Passion for Reading B．My Connection With Parents via Old Books C．My Encounter With the Harry Potter Series D．My Journey With Old BooksHumans make decisions using statistical information every day. For example, we weigh thelikelihood of various factors when deciding what to bet in card games.However, humans aren’t alone in using statistical inferences in decision-making. Until now, human cousins like monkeys and also some birds have been identified as the only animals to show evidence of reasoning based on probability and statistics, which requires advanced mental power. These animals have large brains relative to their body size, which is often associated with high intelligence.Researchers from the University of Barcelona oppugned such statements and suspected that an animal with a small brain relative to its body size could perform statistical reasoning as well.Giraffes were an ideal choice. But researchers had a concern: When we choose a checkout line at a grocery store, we typically just count the number of people in each line, not weighing the probability. Statistical reasoning is quite distinct from basic counting. Giraffes have already exhibited an ability to perform quantity discrimination, being able to tell a larger number of items from a smaller number, which poses a challenge for the researchers to confirm their suspicion.So the research team settled on a special approach where they started with a mixture of carrots the animal desires along with zucchinis (密生西葫芦) they dislike and varied the number and proportion (比例) of both items.The researchers placed different proportions of carrots and zucchinis into two plastic containers to test whether the giraffes could predict a higher likelihood of receiving a carrot. Each test consisted of 20 trials in which a researcher selected a piece of food from each container without showing it to the giraffes. The giraffes then touched the hand they wanted to eat from, using only the information they had from the containers.In the first test, where one container had 20 carrots and 80 zucchinis and another had go carrots and 20 zucchinis, each giraffe chose the hand that had a higher probability of holding a carrot at least 17 times. In the following two tests, the proportion of carrots and zucchinis was changed. Yet again the giraffes chose correctly.The combined results indicated that the researchers’ idea held water.8．What can be inferred in paragraph 2?A．Statistical reasoning is unique to humans.B．Animals with larger bodies have larger brains.C．Large animals are smart enough to perform reasoning.D．Brain size is positively related to intelligence.9．What does the underlined word “oppugned” in paragraph 3 probably mean?A．Declared.B．Questioned.C．Explained.D．Applauded. 10．Why did the research team introduce a special approach to the study?A．To test the giraffes’ ability to perform basic counting.B．To determine whether giraffes prefer carrots or zucchinis.C．To rule out the effect of giraffes’ quantity discrimination.D．To observe the giraffes’ behavior in different situations.11．What do the test results show?A．Giraffes are capable of statistical reasoning.B．Giraffes’ sense of proportion is relatively limited.C．Giraffes rely on visual information to make food choices.D．Giraffes’ food preferences can be changed through training.Many philosophers and psychologists have argued that empathy (共情) is a natural characteristic, hard-wired into our genes and brains. The reasoning goes that each of us has a “level” of empathy and—like our adult height—we’re stuck there for life. This is all well and good if you’re already empathetic, but also means that if you struggle with empathy, you’ll never improve no matter how hard you try.Thankfully, this view is incomplete. Through the right practices, such as diverse friendships and even fiction reading, we can grow our empathy on purpose. Empathy is something like a muscle: left unused, it weakens; put to work, it grows.No emotion is always useful, and that goes for empathy as well. This is especially true for nurses, doctors and other caregivers. These individuals are driven to their work by a deep desire to help others. Patients of empathetic doctors are more satisfied with their care. However, when healthcare professionals care too much, they are at high risk of burnout, tiredness and depression from over-empathizing with others’ suffering.Some psychologists, including myself, are now exploring how people in these professions might empathize in more sustainable ways. For example, empathetic concern-feeling for someone—is distant from emotional empathy—feeling as someone else does. If they can developconcern instead, for example, they can care without falling apart.In another set of studies conducted with Carol Dweek, a Stanford professor of psychology, we found that merely believing empathy is a skill that can be developed inspired people to try harder at it. For instance, people who were encouraged to have a “growth mindset” around empathy, as compared to a fixed mindset, spent more time listening to the suffering of someone of another race and more energy towards trying to understand the opinions of someone from a different part of the political divide.12．What view do many philosophers and psychologists have about empathy?A．It grows when practiced often.B．It is a result of individual experiences.C．It is inborn and difficult to develop.D．It varies depending on one’s upbringing.13．What does the author suggest doctors do?A．Develop their emotional empathy.B．Try to erase their patients’ concern.C．Care for their patients as much as possible.D．Work on improving their empathetic concern.14．Based on Carol Dweek’s studies in which situation are people willingly empathetic?A．If they believe that empathy is flexible.B．If they are given enough attention.C．If they listen to the identical political views.D．If they suffer racial discrimination.15．In which unit of a textbook does the text most likely appear?A．Understanding yourself more.B．Feeling for others.C．Exploring genes and emotions.D．Repairing broken relationships.A Century of ChangeThe last 100 years have seen major transformations in news reporting. Print newspapers dominated the early 1900s, but in November 1922, the dawn (曙光) of radio news arrived when the BBC launched its first daily radio service. It marketed itself as news by and for social elites(精英). 16 In the 1950s, news shifted to television broadcasting. A dramatic change came in 1980 with the creation of America’s Cable News Network (CNN)—the world’s first 24-hour television news network.17 The Internet has become a key site for sharing information, and news is more accessible than it has ever been before. Crises can be reported from on the ground by people who closely understand them. Stories can be shared with the click of a button. 18 In the time it takes for a story to move from a news site to Facebook to your WhatsApp group chat, context is lost and facts go unchecked.In 2016, we witnessed an important moment for the news landscape. Following a US election dogged by dishonesty and misinformation spread largely on social media, Oxford Dictionaries announced “post-truth” as its international word of the year. 19With so much information at our fingertips, the considerable volume of news can be irresistible. Besides, there is increasing uncertainty about what is true and what is not. So it is no wonder that recent years have seen the birth of the “slow journalism” movement, which was first coined in 2007 by Susan Greenberg. 20A．However, that can be dangerous.B．Frequency of the word’s usage rose by 2,000 per cent that year.C．Besides, it required broadcasters to use “received pronunciation”.D．The creation of the World Wide Web in the 1990s changed things again.E．So, the mark of a good story was how soon it was told after it happened.F．It invites us to slow down and pay attention to what’s happening around us.G．People still mainly rely on newspapers for local information.二、完形填空An interactive novel is a text with which the reader can interact.

In the game’s creative mode, players can build structures using blocks.Eighteen-year-old Christopher Slayton started by building the Earth. He used a globe to measure the exact location of every continent lo perfectly copy the planet. He went on to build planets, stars, galaxies and space gas.In a video, Slayton explained that he started skydiving so he could see the plan el from a different perspective, before using mathematical concepts to make sure that the universe was made to an accurate scale. In order to fit all of the planets in the universe into the simulation(模拟), every planet would need to be 700,000 times smaller.Eventually, Slayton was working on structures that are much larger than the Earth, like the sun. He used the brightest blocks in the game to build the star, adding solar flares(光) to make it “feel alive”.Building even larger structures―such as the Pillars of Creation, elephant trunks of interstellar gas and dust in the Eagle Nebula—took Slayton two days to simply make the colors accurate, before painting the stars and their shine in the background.Many other impressive builds have been made in Mine craft. In 2020, a player created a life-size recreation of the Earth, bypassing the game’s built-in height limit to recreate Mount Everest and the Grand Canyon at their full scale.The game is also a powerful learning tool for geography, history and even finance. “Mine craft exposes children to complicated financial systems,” Teacher Gaming co-founder Joel Levin told The Independent. “Perhaps the most effective experiences come from havingwater, and controlling diseases, the technique has improved water and fertilizer use. Meanwhile, it has improved cotton quality and increased cotton production in Xinjiang.“Other technologies for precision agriculture such as plant protection drones(无人机) and harvesting robots can also save resources and costs, increasing farmers’ incomes and reducing their economic losses caused by natural disasters,” Shi said. Drones can automatically generate routes by accessing high-definition farmland maps, fly and spray accurately, and provide standardized agricultural services.However, the development of precision agriculture still faces challenges and falls behind developed countries. Some core equipment and techniques, such as parts of agricultural sensors, still rely on imports, and big shortages remain in smart agriculture technicians. Besides, more financial support is needed to comprehensively promote smart agriculture nationwide, Since artificial intelligence and robotics have been applied in China for a relatively short time, it is necessary to open up a modern path with Chinese characteristics based on local conditions.8．What are the benefits of precision agriculture?A．Improving the environment and saving fertilizers.B．Bringing down labor costs and avoiding mistakes.C．Increasing efficiency and removing some diseases.D．Generating farmland maps and providing services.9．What does the underlined word “optimizing” in Paragraph 3 probably mean? A．Getting something done conveniently.B．Holding a positive attitude to something.C．Makings one thing as effective as possible.D．Employing a traditional way to do something.10．How can precision agriculture be developed properly?A．Importing equipment from some developed countries.B．Working out ways to suit local conditions in different areas.C．Using artificial intelligence and robotics to develop modern cities.D．Seeking financial support abroad to improve the production of crops.11．What can we learn from the passage?A．Smart agriculture has replaced traditional agriculture.B．Artificial intelligence depends on plant pro lection drones.C．Precision agriculture helps boost agricultural modem ization.D．Demonstration bases for smart agriculture have been built throughout China.On the eve of this week’s rail strikes, it was reported that the industry bosses are planning to weed out paper train tickets and close almost 1,000 station ticket offices in England. The transport secretary, Grant Shapps, has made no secret of his desire to see costs saved in this way. Some stations sell only a handful of tickets each week and the vast majority of transactions(交易) have moved online.In the name of cost-cutting, station ticket offices are likely to follow the telephone booth on the comer and become memory. For those who have grown used to the benefits of organizing travel via smartphones, there will be little to feel sorry for. But for people without online access or skills―who tend to be older, poorer, and more fragile-another social barrier will have been built.From medical appointments to payment apps for parking, more and more key services are now delivered digitally. As this revolution takes place, the interests of a significant minority are being ignored to some extent. In the case of health and social care, for example, it will often be those most in need of assistance who are least able to employ electronic devices.The debate over ticket offices offers an opportunity to reflect more broadly on the increasing role of technology in our social landscape. The unavoidable trend towards technology is predictable, but its possible consequences need to be managed with more care. With the expanding range and increasing complexity of digital requirements, the aged are gradually withdrawing from increasing social services in their lives. Ros Altmann, the former pensions minister, recently wrote of being contacted by an elderly woman who no longer drives to her local park, because she cannot download the car parking app required.Much more needs to be invested in helping gain easy online access. Alternative offline options must be maintained for important services. Contactable telephone numbers of relevant staff should always be available. These will cost more. But that is the price of digital transformation.12．Why are the station ticket offices in England planned for closure?A．To cut down some expenses.B．To minimize the use of public transportation.22．A．grateful B．modern C．conventional D．plain 23．A．regular B．messy C．colorful D．rural 24．A．valuing B．saving C．sparing D．killing 25．A．critical B．limited C．single D．pointless 26．A．reminds B．forces C．warns D．requires 27．A．daughter B．doctor C．wife D．fellow 28．A．recall B．envy C．meet D．watch 29．A．voicing B．changing C．rejecting D．evaluating 30．A．scene B．sentence C．section D．photo 31．A．turns on B．fades away C．works out D．lights up 32．A．count B．rise C．cost D．win 33．A．and B．but C．as far as D．as long as 34．A．optimism B．passion C．commitment D．youth 35．A．experience B．appearance C．personality D．inspiration四、未知being nice enough to Piper. Her parents didn’t gel that Piper was wrong either. Sometimes Zara pretended that she didn’t have a sister at all. This was turning into the worst Thanksgiving ever.The way to Grandma and Grandpa’s house was dark and stormy. Suddenly, Dad pulled the car over. “Uh-oh! It looks like we’re not going anywhere,” Mom announced, Zara saw a giant oak tree completely blocking the road.“The wind must have knocked it down,” declared Dad.“Grandma and Grandpa’s house is only two blocks away,” Mom replied. “We can walk the rest of the way. A little rain never hurt anyone.”They all climbed out of the car. Wind and rain whipped Zara’s hair into her face. It was hard to keep her eyes open against the wind. “You’d better hold on to my hand, Piper,” Zara cautioned, but Piper didn’t respond. Zara looked behind her, but Piper wasn’t there. She wasn’t with Mom or Dad, either. “Mom! Dad! Where’s Piper?” Zara shouted in panic. “Piper! Piper!” everyone called. The wind seemed to blow their voices away. Then Zara heard a strange sound coming from the bushes nearby.注意：1.续写词数应为150左右;2.请按如下格式在答题卡的相应位置作答。
