2024年深圳市高三年级第二次调研考试(二模)英语2024.4第二部分阅读(共两节,满分50分)第一节(共15小题;每小题2.5分,满分37.5分)阅读下列短文,从每题所给的A、B、C、D四个选项中选出最佳选项。

AWhat is a GPA?A GPA, or Grade Point Average, typically ranging from one to four, is a number reflecting your course performance on average. It’s used by universities to determine whether students meet academic standards and by students to enhance job prospects or secure admission into post-graduate programs.How to calculate a GPA?● Determine the letter grade and the number of credi t hours for each course you take in a term;● Translate the letter grade to grade points using your school’s grading system;● Multiply the grade points by the credit hours for that course;● Add up all the credit hours for the courses;What are the consequences of failing college courses?● Every failing grade (F) significantly impacts your GPA for that academic year, limiting clubs, organizations and program choices, as competitive programs require top GPAs.● Most financial aid programs require a specific GPA. A sharp drop in GPA due to several course failures may lead to withdrawal from financial aid programs, unless you retake the courses and pass.● For college athletes on sports scholarships, failing courses repeatedly can lead to losing scholarships and team spots.● Failing multiple courses can result in school removal and affect future applications.21. Where is this text probably taken from?A. An academic course guide.B. A campus job fair poster.C. A graduate application form .D. An athletic team schedule.22. What is Jane Smith’s GPA this term?A. 3.3.B. 3.0.C. 2.8.D. 1.0.23. What would be a result if you get one F in college?A. School removal.B. Loss of financial aid.C. Choice limitation.D. Disqualification in sports.B“The mountains are calling and I must go” — the famous quote is from John Muir (1838-1914), who is described as “the wilderness poet” and “the citizen of the universe.” He once jokingly referred to himself as a “poet-geologist-botanist and ornithologist (鸟类学家) -naturalist etc. etc.!” He is known as the Father of American National Parks.Famed documentary filmmaker Ken Burns recently said, “As we got to know him… he was among the highest individuals in America; I’m talking about the level of Abraham Lincoln, Martin Luther King Jr., and Thomas Jefferson — people who have had a transformational effect on who we are.”So where is the quote from? Well, John Muir was a productive writer. Whether he was writing poetry or simply letters to his family, John Muir was always putting pen to paper. The quote is from within one of his many letters written to his sister:September 3rd, 1873Yosemite Valley Dear sister Sarah,I have just returned from the longest and hardest trip I have ever made in the mountains, having been gone over five weeks. I am weary, but resting fast; sleepy, but sleeping deep and fast; hungry, but eating much. For two weeks I explored the glaciers of the summits east of here, sleeping among the snowy mountains without blankets and with little to eat on account of its being so inaccessible. After my icy experiences it seems strange to be down here in so warm and flowery a climate.I will soon be off again, determined to use all the season in carrying through my work — will go next to Kings River a hundred miles south, then to Lake Tahoe and surrounding mountains, and in winter work in Oakland with my pen.Though slow, some day I will have the results of my mountain studies in a form in which you all will be able to read and judge of them. The mountains are calling and I must go, and I will work on while I can, studying incessantly (永不停息地).I will write again when I return from Kings River Canyon.Farewell, with love everlasting.Yours,John24. What can we learn from John Muir’s self-description in paragraph 1?A. He longed to expand his own career.B. He valued his identity as a poet most.C. He wanted to find his real advantage.D. He enjoyed his involvement in nature.25. What did Ken Burns mainly talk about?A. Muir’s political influence.B. A documentary film on Muir.C. Muir’s historic significance.D. The social circle around Muir.26. How did Muir feel when writing the first paragraph of his letter?A. Relieved but regretful.B. Exhausted but content.C. Excited but lonely.D. Defeated but hopeful.27. Why must John Muir go into mountains again?A. To go on with his mountain studies.B. To seek freedom from social connection.C. To attend an appointment in Oakland.D. To experience the hardship of wilderness.CFor decades, scientists thought of the brain as the most valuable and consequently most closely guarded part of the body. Locked safely behind the blood-brain barrier, it was broadly free of the harm of viruses and the battles started by the immune system (免疫系统). Then, about 20 years ago, some researchers began to wonder: is the brain really so separated from the body? The answer, according to a growing body of evidence, is no.The list of brain conditions that have been associated with changes elsewhere in the body is long and growing. Changes in the make-up of the microorganisms (微生物) in the digestive system have been linked to diso rders such as Parkinson’s disease. There is also a theory that infection during pregnancy (孕期)could lead to brain diseases in babies.The effect is two-way. There is a lengthening list of symptoms not typically viewed as disorders of the nervous system, but the brain plays a large part in them. For example, the development of a fever is influenced by a population of nerve cells that control body temperature and appetite. Evidence is mounting that cancers use nerves to grow and spread.The interconnection between brain and body has promising implications for our ability to both understand and treat illnesses. If some brain disorders start outside the brain, then perhaps treatments for them could also reach in from outside. Treatments that take effect through the digestive system, the heart or other organs, would be much easier and less risky than those that must cross the blood-brain barrier.It also works in the opposite direction. Study shows mice have healthier hearts after receiving stimulation to a brain area involved in positive emotion and motivation. Activation of the brain reward centre — called the ventral tegmental area (VTA) — seems to cause immune changes that contribute to it. Working out how this happens could help to destroy cancers, enhance responses tovaccines (疫苗) and even re-evaluate physical diseases that, for centuries, have not been considered as being psychologically driven.28. What do the researchers focus on about the brain?A. Its protecting system.B. Its exposure to diseases.C. Its controlling function.D. Its connection to the body.29. How does the author support his idea in paragraph 2?A. By explaining a theory.B. By providing examples.C. By making comparisons.D. By presenting cause and effect.30. Which best describes treatments that do not cross the blood-brain barrier?A. Cheaper.B. More specific.C. Safer.D. More direct.31. What does the study suggest in the last paragraph?A. Brain health depends on immune changes.B. Brain stimulation leads to negative emotions.C. The brain can help enhance psychological health.D. The brain may be key to treating physical diseases.DAriel Procaccia has thought a lot about how to cut a cake over the last 15 years. As the father of three children, he knows how hard it is to divide a birthday cake to everyone’s satisfaction. But it’s also because Procaccia’s work focuses on exploring the mathematical rules for dividing stuff up fairly. One way to do that is to think abstractly about dessert.For decades, researchers have been asking the seemingly simple question of how to cut a cake fairly. The answer reaches far beyond birthday parties. A mathematical problem at its heart, cake cutting connects strict reasoning to real-world issues of fairness, and so attracts not only mathematicians, but also social scientists, economists and more. “It’s a very elegant model in which you can distill what fairness really is, and reason about it,” Procaccia says.The simplest approach is called the “divider-chooser” method, where one person cuts the cake into two equal pieces in his view, and the other person picks first. Each receives a piece that they feel is as valuable as the other’s. But when personal preferences are taken into account, even the easiest rule becomes complicated. Suppose Alice and Bob are to divide a cake, and Alice knows Bob prefers chocolate, she may knowingly divide the cake unequally so the smaller piece contains more chocolate. Then Bob will choose according to his preference, and Alice will get the larger piece. Both of them are satisfied with what they get, but the meaning of fairness changes in this situation.The cake is a symbol for any divisible good. When cake-cutting principles are employed to settling disagreements, they are potentially helping the world find solutions. Procaccia has used fair division algorithms (算法) to model food distribution. Social scientist Haris Aziz is exploring situations ranging from how to divide up daily tasks to how to best schedule doctors’ shifts in hospitals.Even after decades of investigation, cake cutting isn’t like a simple jigsaw puzzle (拼图) with a well-defined solution. Instead, over time, it has evolved into a kind of mathematical sandbox, a constructive playground that brings together abstract proofs and easy applications. The more researchers explore it, the more there is to explore.32. What does the underlined word “distill” in paragraph 2 mean?A. Get the essence of.B. Find the opposite of.C. Keep the focus on.D. Reduce the impact on.33. What can we learn about fairness from the example given in paragraph 3?A. Its standard is stable.B. It prevents unequal division.C. Its concept is complex.D. It dominates personal preferences.34. What is paragraph 4 mainly about concerning cake cutting?A. The application of its rules.B. The details of its process.C. The problems it produces.D. The harmony it symbolizes.35. What is the best title for the text?A. Who benefits most from fairness?B. How has fairness changed over time?C. What method works best in cake-cutting?D. Why are researchers so interested in cake-cutting?第二节(共5小题;每小题2.5分,满分12.5分)阅读下面短文,从短文后的选项中选出可以填入空白处的最佳选项。

2.回答选择题时,选出每小题答案后,用铅笔把答题卡上对应题目的答案标号涂黑。

如需改动,用橡皮擦干净后,再选涂其他答案标号。

回答非选择题时,将答案写在答题卡上。

写在本试卷上无效。

3.考试结束后,将本试卷和答题卡一并交回。

一、现代文阅读(35分)(一)现代文阅读Ⅰ(本题共5小题,17分)阅读下面的文字,完成1~5题。

材料一:作为两种最主要、也最具代表性的艺术形式,文学和图像之间既存在对立或相互竞争,也存在合作或相互模仿。

一方面,语词的时间性使其在叙事上,具有图像叙事难以企及的天然优势,而图像的直观性和在场感,不可避免地给文学叙事带来冲击。

另一方面,为了强化叙事效果,两者都会或多或少地受彼方叙事策略的影响,进而突破自身媒介的限制展开故事。

比如,当代小说受图像的影响,突破传统小说的因果线性逻辑和语词叙事的时间性,追求图像的直观性和在场感,从而凸显故事的空间维度,达到不同以往的艺术境界。

文学受图像的影响,首先体现在对故事内容或题材的选取上。

敏锐的现代作家往往会因某幅图像带来的视觉震撼而产生创作冲动,借语词将图像内容部分或整体地转译、再现出来,形成故事从图像到文字的同质异构转化。

鲁迅先生在《示众》中,用细致的语言对看客们围观杀头的情景进行反复刻画。

相比语词解读的私人性,图像解读的公共性创造了一个主客体转换的空间,受众由解读主体变成被解读与被言说的对象。

正是在这个基于图像而创设的空间中,充当看客的、愚钝麻木的同胞给鲁迅带来了强烈的心灵冲击,使他意识到国民劣根性的根深蒂固。

除了直接转译图像内容之外,文学家还注意到图像在唤起知性和强化记忆方面的强势作用。

劳拉·里斯曾将宣传广告语比作“钉子”,而将视觉形象比作“锤子”,指出只有依靠“图像之锤”才能更准确有力地将“产品之钉”嵌入消费者的大脑。

3. 依据原文内容,下列说法不正确的一项是
A. 要找到相对最像的“哈姆雷特”,应留意读者能动性与作品限制性的统一。
B. 对个人理解进行提高、修正并与其他读者沟通,有助于读者全面理解作品。
C. 由于文学普遍性的制约,读者在理解人物形象时应当做到以作者设想为主。

A. 与首尔、东京相比,北京、上海中心城区私家车出行比例明显偏高,但 运用轨道交通比例明显偏低,这可能会导致交通拥堵问题。
B. 北京、上海中心城区面积与首尔、东京相差不大,但轨道交通运营里程有较大差距,公共交通动力有限会导致更多人选择私家车出行。
【3题详解】
本题考查学生归纳内容要点,概括中心愿思,并分析概括作者在文中的观点看法的实力。解答此类题目,应先审题,明确题干的要求,如“依据原文内容,下列说法不正确的一项是”,这是要求选出“不正确的一项”,然后阅读选项,辨明检索区间,确定对应语句;联系上下文体会,要死抠字眼;对词语的解说要抓住本质,将说明的含意放在被说明的词语处,看上下文是否连贯、恰当;寻求称代词与称代内容的联系,将称代的内容代入原文理解,联系全文的倾向性,检查该说明是否与全文保持一样。本题C项,“读者在理解人物形象时应当做到以作者设想为主”错,依据原文“读者所推见的人物,却并不确定和作者设想的相同……不过那性格、言动,确定有些类似,大致不差,……要不然,文学这东西就没有普遍性了”,也就是说,文学具有普遍性,所以读者理解人物时,在性格、言动方面与作者设想“有些类似,大致不差”,这并不等于“以作者设想为主”,而仍旧是读者发挥“想象的自由”的同时接受文本“基本的限制”的结果,再者依据第2小题C选项也可推断得知。故选C。

AAre you planning to escape your busy schedule? Here are some fascinating, newly-appointed national-level tourist resorts for you to choose from for your next getaway. Would you like to ski down the slopes (斜坡) of a well-equipped ski resort? Or perhaps you’d like to relax in the lush mountains and clear waters? Let’s begin your new adventure.Xiling Snow Mountain & Huashui Bay Tourist ResortAddress: Chengdu city, Sichuan province.It is centered around two main areas: The Xiling Snow Mountain Ski Resort and the Huashui Bay Scenic Area. The ski resort, featuring seven trails, is the best in the market in Southwest China and the largest and most well-equipped ski resort in the region. Huashui Bay Town has been praised by the United Nations Human Settlements Program as a livable town. The resort offers a variety of accommodation options, including star-rated hotels, inns and campsites.Mulan Lake Tourism ResortAddress: Wuhan city, Hubei provinceCovering a total area of 50 square kilometers, the resort contains distinctive attractions, including Mulan Lake, Mulan Flower Valley and museums steeped in profound history and “Jingchu” culture. “Jingchu” refers to Hubei province and its surrounding areas in ancient China. Here, visitors can be absorbed in a number of activities, including slow and leisurely boating, gentle valley explorations, relaxed walking among museums, as well as appreciation of the lake scenery.Yixian International Rural Tourism ResortAddress: Huangshan city, Anhui provinceYixian International Rural Tourism Resort is located in Yixian county, which is known as a “Village in a Chinese Painting”. This resort is a concentrated display and presentation area of Huizhou culture. It is the first village-themed international rural tourism resort in the country. The resort has a good natural ecological environment and a profound Huizhou culture. Moreover, it also has many international brand hotels, good standard guesthouses, and high-quality homestays.21. What can people do at Mulan Lake Tourism Resort?A. Admire the beauty of flowers and snow.B. Hold an intense rowing competition.C. Participate in professional valley exploration.D. Conduct a regional cultural tour.22. What do Xiling Snow Mountain & Huashui Bay Tourist Resort and Yixian International Rural Tourism Resort have in common?A. They are countryside-themed tourist attractions.B. They are centered around two main regions.C. They offer a variety of accommodation options.D. They have received recognition from the United Nations.23. Who is the text intended for?A. An office worker planning her vacation.B. An adventurer who enjoys tough challenges.C. A student passionate about history and culture.D. A painter who doesn’t want to be disturbed.BMy daughter is a smart kid, but she’d never read an entire chapter book for pleasure. She had never developed any habit of classic deep reading — with two eyes in front of paper, and nothing else going on. When I faced this truth, it felt like a parenting failure. Even though we’d read many storybooks when she was younger and we lived in a house stuffed with books, I hadn’t managed to instill (灌输) one of life’s fundamental pleasures in my kid.As a lifelong reader, I understand how reading enhances the fabric of our experience. Yet my daughter claimed to dislike reading. I told her reading novels was the best way to learn about how people’s insides work. She said she could learn more from the people on social media, who were all about spilling their insides. I said books offered storytelling. She said, “Smartphones.” I said books taught history. She said, “The Internet.”I could not win our debates, because few of my daughter’s arguments against reading seemed wrong to me. Yes, reading is a way to discover new worlds — so is the entire Internet. But that’s not why I wanted my daughter to pick up a book. It was about experiencing a certain magic. You know when an author describes a feeling youdidn’t have, and a hundred lightbulbs go off on the top of your head? I wanted her to have a chance at feeling that.A screen-based medium can’t create this kind of relationship because, by its nature, the medium must fill in all the blanks for you. Books leave space for blanks — and for the internal invention they can inspire.So I decided to cut through all the reasoning with a cold, hard practicality: cash. I told my11-year-old I would pay her $100 to read a novel within a month. Of course, she said yes. She finished the book in seven days. Then she even asked for the sequel (续集) — at no extra charge. Will this lead to her reading Little Women? Will it result in a lifelong habit of reading? I don’t know. What I do know is that I finally opened a new door for her to the printed page. That feels like the best money I ever spent.24. What does the “parenting failure” in paragraph 1 refer to?A. Failure to get along well with her daughter.B. Failure to meet her daughter’s emotional needs.C. Failure to develop a reading habit in her daughter.D. Failure to provide enough storybooks in the house.25. Why does the author want her daughter to read books?A. To help her discover new worlds.B. To help her fill in all the blanks.C. To help her spend less time on the Internet.D. To let her feel a moment of deep connection.26. How does the author feel about spending $100 to encourage her daughter to read?A. She regrets spending the money.B. She is unsure if it will lead to a love of reading.C. She feels disappointed with the final outcome.D. She is confident in her daughter’s future choices.27. What could be the best title for the passage?A. Creating a Reader: A Mother’s JourneyB. Encouraging Reading: Tips for ChildrenC. The Magic of Books in a Digital AgeD. The Decline of Reading Among ChildrenCFor decades it’s been hoped that seawater could be desalinated (淡化) to resolve the problem of drinking water shortage. Yet desalination plants still provide only around one percent of the world’s drinking water. The progress goes slowly as desalination plants are expensive to build and use enormous quantities of energy to run. Energy accounts for one-third to more than half the cost of producing desalinated water.In Saudi Arabia, the world’s largest producer of desalinated water, the process accounts for up to a fifth of the nation’s energy consumption. But all this may be changing. A 2020 study found that, globally, the average cost of desalinated water could more than halve if solar power and battery storage systems were used. Across the world, there are around 180 facilities currently under construction, or in their design phase, mostly in the Middle East andNorth Africa. New sources of renewable energy like solar power mean it’s getting cheaper to power energy-hungry desalination equipment in sunny and water-stressed areas.Egypt and Morocco, for example, are building renewable-powered plants designed both to provide drinking water and to water crops. In South Australia, a self-cooling greenhouse design that uses wind to desalinate seawater for crops is part of a commercial project producing 15 percent of Australian-grown tomatoes. Scientists are also making major breakthroughs, such as new self-cleaning membrane (膜状物) technology, which improve the desalination process.One start-up, Core Power, is developing nuclear-powered offshore plants. Another, Oneka, is employing wave power for desalination units. This wave of growth and innovation is set to continue. A global desalination equipment market valued at 17 billion dollars in 2023 is expected to grow to 32 billion dollars by 2030.But serious challenges remain. Most facilities still use non-renewable fuels to power the plants, and the pouring of processed seawater into the sea poses a threat to sea life. These problems will have to be addressed as a thirsty world looks to the desalination industry to provide its fresh water.28. What results in the slow progress of desalination?A. High production costs.B. Environmental concerns.C. Little demand for fresh water.D. Lack of official support.29. What do the facts in paragraphs 3 and 4 imply concerning the desalination industry?A. It promises a bright prospect.B. It’ll end water shortage soon.C. It’s merely a temporary success.D. It faces huge investment risks.30. In which of the following publications would this text be printed?A. Motor Trend.B. Runner’s World.C. Psychology Today.D. The Economist.31. What would the author probably discuss in the paragraph that follows?A. Why we depend on fresh water to live.B. How to lessen negative effects of desalination.C. What to do to store fresh water against droughts.D. How desalination technologies boost water supply.DAwe(敬畏) experiences typically involve the perception of something incredibly vast or powerful, something that challenges one’s understanding of the world. These are often, but not always, encounters with nature, such aslooking over mountains from an airplane, or standing at the foot of an enormous tree. New developmental research suggests the experience of awe is crucial for a child to grow stronger.Historically, awe has featured in psychological accounts of peak experiences. William James spoke extensively about various spiritual moments that intensely moved him and shaped his viewpoint. He felt strongly these peak experiences made for the deeper development of a person’s inner world.Contemporary researchers theorize that awe may have helped our ancestors survive throughout history and continues to impart positive effects today. Previous studies have shown awe can be instrumental to the formation of social groups and can set off helpful social behaviors among adults.But our research shows that perceptions of awe start much earlier in life. Four to nine-year-old children perceive and respond to awe-inspiring experiences and differentiate them from everyday experiences. When watching fantastic footage (影片片段) of sweeping natural scenes, the children perceived themselves as smaller — a phenomenon known as the “small self”— in comparison with how they felt after watching footage of everyday nature imagery. They further reported being filled with power, believing they were capable of achieving great things. Additionally, they felt a sense of curiosity and a desire to explore more, seeing themselves as adventurers on a journey of discovery.In our busy lives, nevertheless, potential moments of awe often get overlooked. With the pressure to achieve seeping (渗透) into childhood earlier and earlier, it’s easy to understand why you, as a parent, might be more focused on getting your children to the next activity or competition. However, as you become more receptive to sources of awe and knowledgeable about its importance during development, you’ll most likely see them obtain considerable advantages when giving awe experiences greater priority.32. Which aspect of awe experience does the new study highlight?A. Its historical origin.B. Places of its occurrence.C. Its benefits for kids.D. Its impacts on adults’ behavior.33. What does the underlined word “impart” mean in paragraph 3?A. Restrict.B. Withdraw.C. Generate.D. Transform.34. How did the children feel when viewing footage of breathtaking scenery?A. Contented.B. Motivated.C. Panicked.D. Confused.35. What’s the purpose of the author in writing the last paragraph?A. To appeal to parents for a change.B. To advocate a care-free childhood life.C. To state his point on the fast-paced society.D. To describe a common cultural phenomenon.第二节(共5小题;每小题2.5分,满分12.5分)阅读下面短文,从短文后的选项中选出可以填入空白处的最佳选项。

To stress the necessity of garden escape.D.To show the benefits of touring gardens.BMy childhood was a painted picture of sunny sky and rolling green fields stretching to the horizon. It tasted of sharp berries and smelt of sour grapes. My family lived in a cabin (小木屋) in the countryside but I lived in my mother's arms. They were so delicate but strong, her red hair falling around me like a curtain separating me from the world.Childhood was simple. The borders of my village were the furthest my troubles went and monsters only lived in the pages of books. Every day was a waking dream of running races and muddy knees. My village was archaic , dying cabins housing dying farmers with dying traditions,There weren't many children but me and the other boys; boys of butchers and sellers formed our own group.They called us wild. I suppose we were. Trees and mountains formed our playgrounds and fights broke out as easily as sudden laughter. Liberated from the restrictions of society, we would bound into the woods, deeper and deeper until we found a lake which, with a wild yell, we would jump into all at once.My most vivid memories from boyhood center around that lake. Water shone brightly and the sounds of our screams broke into the outcry from birds. The shock of cold water against sweating skin would wake every nerve in my body and my bare feet would hit the sinking muddy bottom. As we submerged (淹没),time would suspend, movements slowing as bubbles rose around us.I was drowning. I was living. I was living. I was drowning.For timelessness or a second (both felt the same), we would suspend, curl up, and then be forced back out into breathing air.We should have known that it wouldn't last forever. Yet, even under the best circumstances, there's something so tragic about growing up: to have your perspective on the people and life around you change; to always struggle to reach a mirror only to find yourself tall enough to see your reflection one day. And find, a different person staring back out at you.24. What does the underlined word "archaic" mean in paragraph 2?A. Borderless.B. Valueless.C. Old-fashioned.D. Poverty-stricken.25.Why did the author consider himself and other children wild?A.They played in the woods crazily.B. They tricked others purposefully.C.They frequently broke social rules.D. They firmly refused school education.26. How does the author introduce his memories of the lake?A.By sharing feelings.B. By expressing ideas.C. By making comparisons.D. By describing characters.27. What message does the author seem to convey in the last paragraph?A.Loneliness and challenges make a man grow up.B.The regret of growth is that you have never tried.C.Growth is often accompanied by sad goodbyes to the past.D.Growth begins when we begin to accept our own weakness.CIn shallow coastal waters of the Indian ocean, Dugong, a kind of sea cow, is in trouble. Environmental problems pose such a major threat to its survival that the International Union for Conservation of Nature (IUCN) upgraded the species' extinction risk status (地位) to vulnerable (脆弱的).Much worse, Dugongs are at risk of losing the protection of the Torres Strait Islanders, who have looked after them historically, hunting them for food sustainably and monitoring their numbers. These native people keep their biodiversity, and have deep knowledge about their environment. But these people are also threatened, in part because rising sea levels are making it difficult for them to live there.This situation isn't unique to Dugongs. A global analysis of 385 culturally important plant and animal species found 68 percent were both biologically vulnerable and at risk of losing their cultural protection.The findings clearly illustrate that biology shouldn't be the primary factor in shaping conservation policy, says anthropologist Victoria Reyes-Garcia. When a culture declines, the species that are important to that culture are also threatened."Lots of conservationists think we need to separate people from nature," says Reyes-Garcia."But that strategy misses the caring relationship many cultural groups have with nature."One way to help shift conservation efforts is to give species a "bio-cultural status,"which would provide a fuller picture of their vulnerability. In the study, the team used a new way to determine a species' risk of disappearing: the more a cultural group's language use declines, the more that culture is threatened. The more a culture is threatened, the more culturally vulnerable its important species are. Researchers then combined a species' cultural and biological vulnerability to arrive at its bio-cultural status. In the Dugong's case, its bio-cultural status is endangered, meaning it is more at risk than its IUCN categorization suggests.This new approach to conservation involves people that have historically cared for them. It can highlight when communities need support to continue their care. Scientists hope it will bring more efforts that recognize local communities' rights and encourage their participation—taking advantage of humans' connection with nature instead of creating more separation.28.What is the relationship between the native people and Dugongs?A.The native people help conserve Dugongs.B. The native people train Dugongs to survive.C. Dugongs ruin the native people's environment.D.Dugongs force the native people to leave home.29.Which statement will Reyes-Garcia probably agree with?A. The protection policy is used incorrectly.B. Culture is connected to species' existence.C. Many groups take good care of each other.D. Conservationists prefer nature over people.30.How is the study method different from previous ones?A. It involves more preservation efforts.B.It relies on the IUCN's classification.C.It highlights the effect of human languages.D.It assesses the biological influence of a species.31.What is the author's attitude towards the latest approach?A.Conservative.B.Favourable.C.Critical.D.Ambiguous.DAdapting to technological advances is a defining part of the 21st-century life. Just two months after being launched in November 2022, OpenAI's ChatGPT has already reached an audience of over 100 million people. While ChatGPT threatens to change writing and writing-related work, the Mesopotamians, who lived 4,000 years ago in a geographical area centered in modern-day Iraq, went through this kind of far-reaching change before us.Ancient Mesopotamia was home to many of civilization's early developments. Its people were world leaders in adapting to technological and cultural changes.They invented the wheel and agriculture, and pioneered advances in mathematics and urbanization. These breakthroughs are reflected in cuneiform(楔形文字) literature, one of the oldest known forms of writing.In its literature, Mesopotamians don't present cultural and technological advances as consistently beneficial. They often represent new technologies being controlled in the service of human conflict and mostly serving the interests of those with high social positions. In some ways, the representation of new technologies in its literature echoes (映现) contemporary concerns about Al: fears of increasing social inequalities and its potential use in information war.In recent years, AI—the newest form of writing —has been used to decipher (破译)the oldest: cuneiform literature. In broader fields, the boundaries of how AI may be used haven't been clearly explained. In January, for example, a top international AI conference banned the use of AI tools for writing scientific papers.Humans have been struggling to invent, use and adapt to technology since our earliest civilizations. But the technology and resulting knowledge are not always evenly distributed. Knowing how we adapted to changing technology in the past helps us more fully understand the human condition and may even help us prepare for the future.32.What does paragraph 2 mainly talk about concerning Mesopotamians?A. Their adaptation to threats.B. Their influences on writing.C. Their contribution to literature.D. Their achievements in civilization.33.What can be inferred about technological advances from paragraph 3?A.They prevent human conflict.B. They bring about hidden dangers.C.They take away people's concerns.D. They lower people's social status.34. What is the current situation of Al according to paragraph 4?A.Its use in literature is popular.B. It is not allowed to finish papers.C. Its range of application is undefined.D. It is not accepted in broader fields.35.Which of the following is a suitable title for the text?A. How People Can Use the Latest TechnologyB. How ChatGPT Will Threaten Writing and WorkC.What AI Will Do by Learning Cuneiform LiteratureD.What History Can Teach Us About New Tech's Impact第二节 (共5小题;每小题2.5分,满分12.5分)阅读下面短文,从短文后的选项中选出可以填入空白处的最佳选项。
