限时阅读3——主旨大意 坚持不懈地进行语篇训练，才能提升阅读速度。 (2025·湖南省九校联盟高三下第二次联考)In the race to develop artificial intelligence (AI) systems that can outperform humans, DeepSeek—one cutting­edge technology, developed by a team of researchers in Asia, has already demonstrated its ability to revolutionize industries ranging from healthcare to finance. However, as DeepSeek's capabilities grow, so do the ethical questions surrounding its use. One of the most impressive features of DeepSeek is its ability to analyze vast amounts of data in real time. For example, in healthcare, it has been used to predict disease outbreaks by analyzing patterns in patient data. In finance, it has helped banks find fraud with very high accuracy. Yet, these advancements come with a price. It raises concerns about privacy and consent (允许). Who owns the data being used, and how can we ensure it is not misused? Another area where DeepSeek has shown promise is in natural language processing (NLP). Its ability to understand and generate human language has made it a valuable tool for translation services. However, critics argue that this technology could be weaponized to spread misinformation or influence public opinions. The recent controversy over AI­generated deepfake videos is also a reminder of the potential dangers. Despite these challenges, people who support DeepSeek argue that its benefits far outweigh the risks. They point to its potential to solve some of the world's most pressing problems, such as climate change and poverty. For instance, DeepSeek has been used to make smarter cities consume less energy, reducing carbon emissions significantly. In agriculture, it has helped farmers increase crop yields by analyzing soil data. The debate about DeepSeek's ethical influences is far from settled. Some call for stricter regulations to prevent misuse, while others believe that innovation should not be stopped because of fear. As we move forward, one thing is clear: the future of AI will depend on our ability to pursue balance between progress and responsibility. 篇章导读：本文是一篇说明文。文章主要讨论了DeepSeek技术的伦理影响问题。 1．What is an advantage of DeepSeek in the field of healthcare according to the text?

On the weekends she competed in marathons around Europe. But life threw her a near deadly blow. While teaching a PE class, she was hit in the head with a baseball. The impact was so great it left her with a brain injury and 70 percent vision loss, permanently blinding her in one eye. She spent 26 months in seven different hospitals, at times wishing it would just all end. Desperately, Wheatley set out to find comfort and healing in nature. She travelled to Nepal where a friend convinced her to run in the Annapurna 100 with him. The power from that race changed her life and eventually had her looking up at the tops of the mountains. Project Vision 8，000 was born. And she began her mission to stand on top of the world's 14 highest mountains, towering 8，000 metres above sea level, to show herself and others the power in choice and possibility. Colours, and touch help guide her on the mountain and she has never once felt too tired to carry on. “The only thing constant is change, so when the weather gets really bad or a storm is coming in, I know it is going to pass.” So far, she's had few problems standing among giants, but she admits she continues to struggle with overcoming: the “mountains of her mind”. Having already stared death in the face, Wheatley has great respect for the mountains and the mission she is on. But she's not scared. The experience almost claimed her life, but it is now the driving force and fuel behind her success. At every icy peak, she smiles and takes a quick video with a breathless “so very thankful” whispered into the thin air. 篇章导读：本文是一篇记叙文。文章主要讲述了Jill Wheatley (吉尔·惠特利)因遭遇意外而脑部受损并丧失了70%的视力，一只眼睛永久性失明。但她没有放弃，并决定通过登山来寻找慰藉，最终转变了对逆境的态度。 5．What happened to Wheatley according to Paragraph 1?

When people are hooked up to these machines, tasks, such as reading or doing math problems, each have corresponding areas of the brain where activities can be observed. But when researchers got the participants to listen to music, they saw fireworks. Some areas of their brains were lighting up at once, as they processed the sound, took it apart to understand elements like melody and rhythm, and then put it all back together into combined musical experience. Yet when scientists turned from observing the brains of music listeners to those of musicians, the little backyard fireworks became a massive celebration. It turns out that playing music is similar to a full­body workout. Playing a musical instrument engages practically every area of the brain at once, especially the visual, auditory, and motor cortices (大脑皮层)． The most obvious difference between listening to music and playing it is that the latter requires fine motor skills, which are controlled by both hemispheres (半球) of the brain. It also combines the linguistic and mathematical accuracy, in which the left hemisphere is more involved, with the novel and creative content that the right excels in. Because making music also involves crafting and understanding its emotional content and message, musicians often have higher levels of executive function. And, indeed, musicians exhibit enhanced memory functions, creating, storing, and retrieving memories more quickly and efficiently. Studies have found that's because musicians use their highly connected brains to attach each memory to multiple labels, such as a conceptual label, an emotional label, an audio label, and a contextual label, like a good Internet search engine. The recent research about the mental benefits of playing music has advanced our understanding of mental function, revealing the inner rhythms and complex interplay that make up the amazing orchestra of our brain. 篇章导读：本文是一篇说明文。文章介绍了研究发现音乐对大脑有积极影响，而且与听音乐相比，演奏音乐能激活更多的大脑区域，从而给演奏者带来更多的好处。 9．What does “fireworks” underlined in Paragraph 1 refer to? A．A grand celebration of sound. B．An act of playing instruments. C．A burst of activities in the brain. D．A visual effect in performances. 答案：C 解析：指代判断题。根据画线词后文“Some areas of their brains ... combined musical experience.”可知，当人们听音乐时，大脑的某些区域会活跃起来，开始处理听到的声音。由此可知，此处firework是比喻用法，指大脑中多个区域被同时激活、剧烈活动的景象。故选C。 10．In what way is playing music different from listening to music? A．It rarely depends on motor skills. B．It awakens most of the brain areas. C．It uses both hemispheres of the brain. D．It connects novel and creative content. 答案：C 解析：细节理解题。根据第三段中的“The most obvious difference ... of the brain.”可知，演奏音乐与听音乐的不同之处在于前者用到了大脑的两个半球。故选C。 11．Why do musicians perform better memory functions? A．They practise instruments frequently. B．They label memories as different types. C．They connect the key information efficiently. D．They focus on the emotional content of music. 答案：B 解析：推理判断题。根据第四段中的“Studies have found ... to multiple labels”可推知，音乐家们表现出更好的记忆功能是因为他们将记忆划分为不同的类型。故选B。 12．What is the main idea of the text? A．Listening to music has various mental benefits. B．Art activities have positive impacts on the brain. C．Playing music activates the brain more than listening. D．Those who play instruments are born more intelligent. 答案：C 解析：主旨大意题。通读全文可知，文章主要介绍了研究发现音乐对大脑有积极影响，而且与听音乐相比，演奏音乐能激活更多的大脑区域，从而给演奏者带来更多的好处。故选C。 词汇：①breakthrough n. 突破　②massive adj. 巨大的　③benefit n. 好处，益处　④turn out 结果是　⑤make up 组成 佳句：It turns out that playing music is similar to a full­body workout.事实证明，演奏音乐与全身性的锻炼有着相似之处 (2025·贵州省黔东南州第四次模拟考试暨贵阳市高三下二模)In 2024, 56­year­old Madonna returned with a new album, and the tight jaw line and smart muscle state on the red carpet set off a hot search. What is Madonna's “reverse growth password”？ How did she go from postpartum (产后的) depression to red carpet queen? Sophie Chen, her postpartum restorer and New York's top physical therapist, revealed for the first time: “Madonna receives acupuncture twice a week, focusing on the ‘triangle of facial rejuvenation (恢复青春)’. Combined with body acupuncture to regulate endocrine (内分泌), the body fat rate decreased from 22% to 18% and the collagen (胶原蛋白) density increased by 37% within 6 months.” Madonna said in the documentary: “I am not fighting against aging, but letting my body remember the feeling of being young.” The wisdom of acupuncture is precisely to achieve “elegant aging” by regulating the self­healing of the human body. When western technology meets eastern philosophy, this 3 mm silver needle may be the key to a “healthy life”． Nowadays, acupuncture has been widely applied in more than 190 countries and regions around the world, serving as a window for the world to understand traditional Chinese medicine. In Brazil, acupuncture is highly popular among the people. In 2006, the Brazilian Ministry of Health decided to incorporate acupuncture into the Brazilian Unified Health System. Many TV hosts in São Paulo often use acupuncture and tuina massage to relax and regulate their bodies. As we continue to explore the wonders of traditional Chinese medicine, acupuncture stands out as a shining example of the wisdom of our ancestors. Whether you are seeking relief from pain, looking to improve your overall well­being, or simply curious about alternative therapies, acupuncture is definitely worth learning more about. 篇章导读：本文是一篇说明文。文章主要介绍了针灸助力Madonna (麦当娜)逆龄及针灸在世界各地的广泛应用。 13．Why does the author use two questions in Paragraph 1?

D．To analyze the combination of the east and the west. 答案：C 解析：推理判断题。通读全文可知，文章开篇通过Madonna的逆生长引出针灸这一话题，接着介绍了针灸如何帮助Madonna实现“优雅衰老”，然后提到针灸在全球190多个国家和地区均有广泛应用。由此可推知，文章的主要目的是展示针灸的好处和普及。故选C。 词汇：①reverse v. 颠倒　adj. 相反的　②reveal v. 揭示，透露　③acupuncture n. 针灸　④regulate v. 调节；控制　⑤set off 引发 佳句：When western technology meets eastern philosophy， this 3 mm silver needle may be the key to a “healthy life”. 当西方科技遇上东方哲学，这根3毫米的银针或许正是开启“健康人生”的关键。 (2025·江苏省南京市高三下第二次模拟)This might sound impossibly old­fashioned, but I still like the idea that education is about learning: facts, skills, culture, analysis, inspiration. It's supposed to make us better citizens. But over the last decade, the goal of learning has given way to grades and degrees. The unfortunate result has been inflation (膨胀) of both. They rise ever higher; learning doesn't. To avoid discouraging students, some school districts did away with D and F grades. Grade­point averages have consistently risen even though scores on nationwide standardized exams such as the SAT have not. It's not that I think standardized tests are the final word in measuring excellence. But when the gaps between grades and test scores are this wide and consistent, parents and the public should not be fooled. That's true not just of low­achieving students. In a survey, educators said that close to half of students argue for higher grades than they earn, and 8 out of 10 teachers give in. It's hard to blame them: A third or more of students and parents disturb them when they don't. Unearned grades are damaging in many ways. Some students, armed with good grades, march off to college to find themselves in remedial (补习的) classes because they haven't learned enough to take college­level courses. Employers complain that high school and even college graduates lack basic skills needed in the workforce. There are also complaints from college professors that the students aren't even good at reading books. Grade inflation has followed students into college. Some professors hesitate to grade accurately because of student evaluations, which are often more negative for tough graders. Remember that about 70% of college instructors are adjunct (兼职) professors who have few job protections. Many Ivy League students have learned to cherry­pick easy­grading professors. Yet a Brown University study found that students taking courses from professors with stricter grading standards learned more. We have to ask ourselves as a society: Do we want college to be a place of intellectual growth—or a performative exercise in grade fishing? 篇章导读：本文是一篇议论文。文章主要讨论了成绩膨胀的现象，并指出成绩膨胀会导致学生实际学习能力不足，不能满足雇主的需求。作者认为应该重视真正的学习，而不是单纯追求高分。 17．What are parents fooled into thinking? A．SAT is the best measure of their children's abilities. B．The purpose of education is to make better citizens. C．Grade­point averages are vital for college application. D．Children's high grades reflect their exceptional abilities. 答案：D 解析：细节理解题。根据第三段“Grade­point averages have consistently risen ... parents and the public should not be fooled.”可知，学生的平均绩点持续上升，但全国标准化考试成绩却没有相应提高，成绩和考试分数差距很大且持续存在，于是父母被误导认为孩子的高分反映了他们卓越的能力。故选D。 18．What is a consequence of grade inflation? A．Employers favor students with higher degrees. B．Graduates fall short of employers' expectations. C．Remedial classes become required courses in college. D．Low­achieving students find it harder to enter college. 答案：B 解析：细节理解题。根据倒数第二段中的“Employers complain that ... in the workforce.”可知，雇主抱怨高中生甚至大学毕业生缺乏职场所需的基本技能，即成绩膨胀的后果是毕业生达不到雇主的期望。故选B。 19．What can be inferred from the last paragraph? A．Tough graders desire job security. B．Strict grading promotes real learning. C．Student evaluations fuel intellectual growth. D．Easy­grading professors start grade inflation. 答案：B 解析：推理判断题。根据最后一段中的“Yet a Brown University study ... standards learned more.”可知，布朗大学的一项研究发现，选修评分标准更严格的教授所授课程的学生学到的知识更多。由此可推知，严格的评分能促进真正的学习。故选B。 20．What is the best title of the text? A．The game of scores B．Today, Grade A is for average C．The force behind grade inflation D．Now, learning takes the front seat 答案：B 解析：标题判断题。文章主要讨论了成绩膨胀的现象，指出现在学生的成绩虚高，实际能力不足，很多学生和家长被高成绩所误导，教师给分宽松的现象普遍存在，而严格的评分能促进真正的学习。由此可知，B项(如今，A 等级只是平均分)最适合作为文章标题。故选B。 词汇：①consistently adv. 一贯地，始终　②accurately adv. 精确地，准确地　③negative adj. 消极的，负面的　④cherry－pick v. 择优挑选　⑤march off 离开，匆匆离去 佳句：But over the last decade， the goal of learning has given way to grades and degrees. 但过去十年间，学习的目标已被成绩和学位所取代。 学科网（北京）股份有限公司 $
