And 61 of them are not even supposed to be used in such products. “It’s not clear why the latter chemicals, which are not on lists of those authorized for use in food containers, are in such packaging.” says the study’s author Birgit Geueke. The study focused on a class of chemicals called perfluoroalkyl and polyfluoronlkyl substances (PFASs), which are sometimes called “forever chemicals” because they don’t break down readily in the environment or in the body. That’s because their characteristic carbon-fluorine bond is one of the strongest in nature. For decades, these substances have been used in a wide range of consumer products, from cookware to pesticide s to cosmetics, because they are proof against water and grease. Geueke and her team found a mismatch between what they detected in actual products and a database of PFAS chemicals authorized for use in food packaging. About 140 PFASs are known to be used in food packaging, but only seven of the 68 chemicals in the study were on this list. Geueke says it’s unclear how or why the other 61 chemicals turned up. David Andrews, a chemist and toxicologist at a nonprofit environmental advocacy organization, suggests it’s possible that unknown impurities emerged during the manufacturing of the authorized chemicals or that the authorized PFASs degrade over time. This class of chemicals includes many long-chain molecules, and they can break into shorter chains that are simply different types of PFASs. PFASs have been found in human blood and breast milk, drinking water, soil and other startling places around the world. Exposure to some of the most studied PFASs has been associated with cancer. reproductive problems and lessened responses to vaccines. “There’s an incredible body of scientific evidence linking PFAS chemicals to health harm,” says Andrews. Many countries are evaluating restrictions of PFASs in food packaging. Chemical industry representatives have advocated for dealing with PFASs as individual chemicals. Before publishing the new study. Scientific American reached out to the American Chemistry Council (ACC), a chemistry industry trade association, about it, but the organization did not reply. On its dedicated PFAS webpage. ACC notes that “all PFASs are not the same. Each individual chemical has its own unique properties and uses.” Andrews and Geueke both say the presence of unknown PFASs in food packaging is good reason to regulate these chemicals as a single class—a position shared with many other scientific experts and environmental protection groups. There are more than 12,000 known PFASs, and scientists don’t know much about most of them. “Only some PFASs have ever been tested for toxicity,” Geueke says, and “there are probably other ways to produce food packaging.” 14．Paragraph 3 is mainly about ______. A．the potential usage of the unknown impurities B．the authorization of food packaging chemicals C．the likely transforming process from PFASs into new chemicals D．the possible explanation for the presence of unauthorized PFASs 题型02 文章大意题 【题型诠释】 一、提问方式 What’s the main idea/point of the passage?

Some Generation Z trend followers are now viewing it as a form of self-care, but doctors warn too much could be “sign of depression”. Are these extended breaks really wise for one’s mental health — or could they be a cause for concern? Dr. Ryan Sultan, a professor at Columbia University in New York, who treats many young people, called the bed rotting trend attractive. “In our culture today, with too much to do, too many expectations and too much productivity, many young individuals (个人) are feeling burned out and often aren’t getting enough sleep. It’s easy to see why taking time off to lie around is attractive,” Sultan said. “In many ways, this is beneficial. It’s a chance to get away from real-life problems and clear your head before returning to life in a better state of mind, ” he added. For the downside, however, he said a long-term need or desire for bed rotting could do harm to one’s physical health. Spending too many daytime hours in bed — awake or not — could destroy sleep schedules. Our brains are fine-tuned for sleep in darkness and alertness in light. Lying in bed half-asleep during the day will worsen sleep schedules — once that happens, it is a challenge to fix. It could also lead to blood pressure problems and obesity (肥胖). Long-term need or desire for bed rotting could also be a warning sign of depression, according to a mental health expert. Dr. Marc Siegel, professor of medicine at NYU Langone Medical Center and a Fox News medical contributor, agreed that while some downtime can be useful in terms of de-stressing and rejuvenation (更新), too much bed rotting is a bad health practice. In addition to increasing the risk of depression, it contributes to decreased motivation (动力) as well. Instead of bed rotting, Siegel recommends regular exercise as a better form of de-stressing. While the occasional lazy day can be beneficial, too much could have the opposite effect. If it happens every day, that’s a fairly sensitive test for depression. Those who lack the motivation to get out of bed could also try calling or texting a family member for support, socializing with close friends, finding a small task to complete, or reaching out to a medical professional for help. 8．What is the passage mainly talking about? A．Different opinions on how to become motivated. B．Main causes of the long-term need for bed rotting. C．Practical suggestions for young people to deal with stress. D．Possible problems from lying in bed for extended periods of time. 题型03 标题归纳题 【题型诠释】 一、提问方式 The best title of the passage is ________. Which of the following is the best title of the passage?

There has been a debate about this possibility for decades. Recently two analyses have put the surprising cognitive (认知) abilities of dinosaurs — and their potential limitations — in a new light. In one study, Suzana Herculano-Houzel at Vanderbilt University calculated the likely number of neurons (神经细胞) in dinosaurs’ pallium, a brain structure that is responsible for advanced cognitive functions. Research suggests that it is the number of neurons in these areas, rather than the brain size, that indicates an animal’s cognitive potential. For example, despite having a very small head, birds have more densely packed brain cells than many mammals (哺乳动物) and so can possess roughly as many neurons as monkeys. The result is that some birds show great cognitive abilities, comparable to the smartest non-human mammals. And it is precisely birds, being the only surviving lineage (宗系) of dinosaurs, that are Herculano-Houzel’s foundation. By comparing the relationship between brain size, number of neurons and body size in numerous existing birds and available fossils of dinosaurs, Herculano-Houzel concludes that a large dinosaur such as T. rex could have housed two billion to three billion neurons in its pallium. If so, dinosaurs could have had the capacity for tool use and planning for the future. But neurons’ number may not be enough. For intelligence, brain architecture also matters. And this could be the weakness of dinosaurs, argues Anton Reiner from the University of Tennessee. Over 350 million years of separate evolution, mammals and dinosaurs found two rather different ways to organize cognitive functions. The mammalian neurons are organized in a relatively thin layer formed by compact columns. In each column, different parts can communicate with one another over short distances. In contrast, in the dinosaurs that survive today, namely birds, the organization is less compact. According to Reiner, expanding brain capabilities beyond a certain point could make the structure far more complex and less efficient than it is in humans. If this were the case, an increase in brain size would correspond to a greater distance between different parts of the brain, slowing down their communication. The issue remains open to debate. Herculano-Houzel and Reiner each published a paper with rejections to the other’s argument. Meanwhile, other scientists have entered the fight. For example, neurobiologist Giorgio Vallortigara assumes that speed in transmitting information between networks of neurons is probably one of dinosaurs’ strengths. Whatever the truth is, understanding how and if brain architecture imposes limits on the development of cognition could reveal much about the evolution of abilities and behaviors of various animals. Also, this debate may tell us more about our own species than about dinosaurs. 4．Which would be the best title for the passage? A．Are Dinosaurs Comparable to Humans in Intelligence? B．Are Dinosaurs with Bigger Brains the Ultimate Geniuses? C．How Smart Were Dinosaurs? New Studies Fuel the Debate D．Can Dinosaurs Outsmart Birds? Researches Cast a New Light 【高考真题】 【2024北京卷】 Franz Boas’s description of Inuit (因纽特人) life in the 19th century illustrates the probable moral code of early humans. Here, norms (规范) were unwritten and rarely expressed clearly, but were well understood and taken to heart. Dishonest and violent behaviours were disapproved of; leadership, marriage and interactions with other groups were loosely governed by traditions. Conflict was often resolved in musical battles. Because arguing angrily leads to chaos, it was strongly discouraged. With life in the unforgiving Northern Canada being so demanding, the Inuit’s practical approach to morality made good sense. The similarity of moral virtues across cultures is striking, even though the relative ranking of the virtues may vary with a social group’s history and environment. Typically, cruelty and cheating are discouraged, while cooperation, humbleness and courage are praised. These universal norms far pre-date the concept of any moralising religion or written law. Instead, they are rooted in the similarity of basic human needs and our shared mechanisms for learning and problem solving. Our social instincts (本能) include the intense desire to belong. The approval of others is rewarding, while their disapproval is strongly disliked. These social emotions prepare our brains to shape our behaviour according to the norms and values of our family and our community. More generally, social instincts motivate us to learn how to behave in a socially complex world. The mechanism involves a repurposed reward system originally used to develop habits important for self-care. Our brains use the system to acquire behavioural patterns regarding safe routes home, efficient food gathering and dangers to avoid. Good habits save time, energy and sometimes your life. Good social habits do something similar in a social context. We learn to tell the truth, even when lying is self-serving; we help a grandparent even when it is inconvenient. We acquire what we call a sense of right and wrong. Social benefits are accompanied by social demands: we must get along, but not put up with too much. Hence self-discipline is advantageous. In humans, a greatly enlarged brain boosts self-control, just as it boosts problem-solving skills in the social as well as the physical world. These abilities are strengthened by our capacity for language, which allows social practices to develop in extremely unobvious ways. 34. Which would be the best title for this passage? A. Virtues: Bridges Across Cultures B. The Values of Self-discipline C. Brains: Walls Against Chaos D. The Roots of Morality 【2023北京卷】 What is life? Like most great questions, this one is easy to ask but difficult to answer. The reason is simple: we know of just one type of life and it’s challenging to do science with a sample size of one. The field of artificial life-called ALife for short — is the systematic attempt to spell out life’s fundamental principles. Many of these practitioners, so-called ALifers, think that somehow making life is the surest way to really understand what life is. So far no one has convincingly made artificial life. This track record makes ALife a ripe target for criticism, such as declarations of the field’s doubtful scientific value. Alan Smith, a complexity scientist, is tired of such complaints. Asking about “the point” of ALife might be, well, missing the point entirely, he says. “The existence of a living system is not about the use of anything.” Alan says. “Some people ask me, ‘So what’s the worth of artificial life?’ Do you ever think, ‘What is the worth of your grandmother?’” As much as many ALifers hate emphasizing their research’s applications, the attempts to create artificial life could have practical payoffs. Artificial intelligence may be considered ALife’s cousin in that researchers in both fields are enamored by a concept called open-ended evolution (演化). This is the capacity for a system to create essentially endless complexity, to be a sort of “novelty generator”. The only system known to exhibit this is Earth’s biosphere. If the field of ALife manages to reproduce life’s endless “creativity” in some virtual model, those same principles could give rise to truly inventive machines. Compared with the developments of Al, advances in ALife are harder to recognize. One reason is that ALife is a field in which the central concept — life itself — is undefined. The lack of agreement among ALifers doesn’t help either. The result is a diverse line of projects that each advance along their unique paths. For better or worse, ALife mirrors the very subject it studies. Its muddled (混乱的) progression is a striking parallel (平行线) to the evolutionary struggles that have shaped Earth biosphere. Undefined and uncontrolled, ALife drives its followers to repurpose old ideas and generated novelty. It may be, of course, that these characteristics aren’t in any way surprising or singular. They may apply universally to all acts of evolution. Ultimately ALife may be nothing special. But even this dismissal suggests something：perhaps, just like life itself throughout the universe, the rise of ALife will prove unavoidable. 34．Which would be the best title for the passage? A．Life Is Undefined. Can AI Be a Way Out? B．Life Evolves. Can AI Help ALife Evolve, Too? C．Life Is Undefined. Can ALife Be Defined One Day? D．Life Evolves. Can Attempts to Create ALife Evolve, Too? 【2022年北京卷】 Quantum ( 量子 ) computers have been on my mind a lot lately. A friend has been sending me articles on how quantum computers might help solve some of the biggest challenges we face as humans. I’ve also had exchanges with two quantum-computing experts. One is computer scientist Chris Johnson who I see as someone who helps keep the field honest. The other is physicist Philip Taylor. For decades, quantum computing has been little more than a laboratory curiosity. Now, big tech companies have invested in quantum computing, as have many smaller ones. According to Business Weekly, quantum machines could help us “cure cancer, and even take steps to turn climate change in the opposite direction.” This is the sort of hype ( 炒作 ) that annoys Johnson. He worries that researchers are making promises they can’t keep. “What’s new,” Johnson wrote, “is that millions of dollars are now potentially available to quantum computing researchers.” As quantum computing attracts more attention and funding, researchers may mislead investors, journalists, the public and, worst of all, themselves about their work’s potential. If researchers can’t keep their promises, excitement might give way to doubt, disappointment and anger, Johnson warns. Lots of other technologies have gone through stages of excitement. But something about quantum computing makes it especially prone to hype, Johnson suggests, perhaps because “‘quantum’ stands for something cool you shouldn’t be able to understand.” And that brings me back to Taylor, who suggested that I read his book Q for Quantum. After I read the book, Taylor patiently answered my questions about it. He also answered my questions about PyQuantum, the firm he co-founded in 2016. Taylor shares Johnson’s concerns about hype, but he says those concerns do not apply to PyQuantum. The company, he says, is closer than any other firm “by a very large margin ( 幅度 )” to building a “useful” quantum computer, one that “solves an impactful problem that we would not have been able to solve otherwise.” He adds, “People will naturally discount my opinions, but I have spent a lot of time quantitatively comparing what we are doing with others.” Could PyQuantum really be leading all the competition “by a wide margin”, as Taylor claims? I don’t know. I’m certainly not going to advise my friend or anyone else to invest in quantum computers. But I trust Taylor, just as I trust Johnson. 34. Which would be the best title for the passage? A. Is Johnson More Competent Than Taylor? B. Is Quantum Computing Redefining Technology? C. Will Quantum Computers Ever Come into Being? D. Will Quantum Computing Ever Live Up to Its Hype? 【2021年北京卷】 Early fifth-century philosopher St．Augustine famously wrote that he knew what time was unless someone asked him．Albert Einstein added another wrinkle when he theorized that time varies depending on where you measure it．Today's state-of-the-art atomic（原子的） clocks have proven Einstein right．Even advanced physics can't decisively tell us what time is, because the answer depends on the question you're asking． Forget about time as an absolute．What if，instead of considering time in terms of astronomy,we related time to ecology？What if we allowed environmental conditions to set the tempo（节奏） of human life？We're increasingly aware of the fact that we can't control Earth systems with engineering alone，and realizing that we need to moderate（调节）our actions if we hope to live in balance．What if our definition of time reflected that？ Recently，I conceptualized a new approach to timekeeping that's connected to circumstances on our planet，conditions that might change as a result of global warming．We're now building a clock at the Anchorage Museum that reflects the total flow of several major Alaskan rivers，which are sensitive to local and global environmental changes．We've programmed it to match an atomic clock if the waterways continue to flow at their present rate．If the rivers run faster in the future on average，the clock will get ahead of standard time．If they run slower，you'll see the opposite effect． The clock registers both short-term irregularities and long-term trends in river dynamics．It's a sort of observatory that reveals how the rivers are behaving from their own temporal frame（时间框架），and allows us to witness those changes on our smartwatches or phones．Anyone who opts to go on Alaska Mean River Time will live in harmony with the planet．Anyone who considers river time in relation to atomic time will encounter a major imbalance and may be motivated to counteract it by consuming less fuel or supporting greener policies． Even if this method of timekeeping is novel in its particulars，early agricultural societies also connected time to natural phenomena．In pre-Classical Greece，for instance，people“corrected”official calendars by shifting dates forward or backward to reflect the change of season．Temporal connection to the environment was vital to their survival．Likewise，river time and other timekeeping systems we're developing may encourage environmental awareness． When St．Augustine admitted his inability to define time， he highlighted one of time 's most noticeable qualities：Time becomes meaningful only in a defined context．Any timekeeping system is valid，and each is as praiseworthy as its purpose． 31 What is the main idea of Paragraph 1？ A. Timekeeping is increasingly related to nature． B. Everyone can define time on their own terms． C. The qualities of time vary with how you measure it． D. Time is a major concern of philosophers and scientists． 【2020北京卷】 For the past five years, Paula Smith, a historian of science, has devoted herself to re-creating long-forgotten techniques. While doing research for her new book, she came across a 16th-century French manuscript（手稿）consisting of nearly 1,000 sets of instructions, covering subjects from tool making to finding the best sand. The author's intention remains as mysterious（神秘）as his name; he may have been simply taking notes for his own records. But Smith was struck mainly by the fact that she didn't truly grasp any of the skills the author described. "You simply can't get an understanding of that handwork by reading about it," she says. Though Smith did get her hands on the best sand, doing things the old-fashioned way isn't just about playing around with French mud. Reconstructing the work of the craftsmen（工匠）who lived centuries ago can reveal how they viewed the world, what objects filled their homes, and what went on in the workshops that produced them. It can even help solve present-day problems: In 2015, scientists discovered that a 10th-century English medicine for eve problems could kill a drug-resistant virus. The work has also brought insights for museums, Smith says. One must know how on object was made in order to preserve it. What's more, reconstructions might be the only way to know what treasures looked like before time wore them down. Scholars have seen this idea in practice with ancient Greek and Roman statues. These sculptures were painted a rainbow of striking colours. We can't appreciate these kinds of details without seeing works of art as they originally appeared-something Smith believes you can do only when you have a road map. Smith has put the manuscript's ideas into practice. Her final goal is to link the worlds of art and science back together: She believes that bringing the old recipes to life can help develop a kind of learning that highlights experimentation, teamwork, and problem solving. Back when science—then called “the new philosophy”—took shape, academics looked to craftsmen for help in understanding the natural world. Microscopes and telescopes were invented by way of artistic tinkering（修补）, as craftsmen experimented with glass to better bend light. If we can rediscover the values of hands-on experience and craftwork, Smith says, we can marry the best of our modern insights with the handiness of our ancestors. 41. Which would be the best title for this passage? A. Craftsmen Set the Trends for Artists B. Craftsmanship Leads to New Theories C. Craftsmanship Makes Better Scientists D. Craftsmen Reshape the Future of Science 【最新模考】 【2024·北京大兴·三模】 We now live in an age of instant images and emoji, when 10,000 copies of a picture can be spread around the world in seconds by sliding a finger half an inch across a phone screen. This would have been unbelievable and unimaginable 20 years ago. But it is in the world of hand-copied manuscripts (手稿) 1,000 years old or more that the digital revolution has had some of its most profound and obvious beneficial effects. What may have taken three years to write out can today be printed out in three seconds. There are now tens of thousands of once unique documents which have been digitized and placed online for anyone to access all around the world, and this is a vast, democratizing wonder. Take the Parker Library in Cambridge, which contains the scholarly works during the Reformation (宗教改革时期) and collected by Matthew Parker. It has been digitized in a project with Stanford University, and in 2018 the site was opened to all comers to browse after 10 years behind scholarly paywalls. What is astonishing is not just the texts themselves, but the pictures: the illuminations (插图) on some of the manuscripts show off the fertility and vividness of the medieval imagination. Digitized collections of these sorts cannot entirely substitute for real libraries. To touch with your own hand a parchment (羊皮纸) from a medieval monk is an experience no screen can offer, but it is one which must always be restricted to a lucky few. There are some things so old and fragile that even being looked at may damage them. The caves at Lascaux had to be closed to protect the paintings from the breath of tourists and replaced by a virtual display. Yet in some ways these copies are better than the originals. Reproductions of a high enough quality make obvious detail that’s invisible to the native eye. What’s more, digital collections can be gathered on one screen from across the globe. The International Dunhuang Project reunites on screen tens of thousands of Buddhist scrolls and artifacts in western China. What is possible with this one collection should fairly soon be possible with all the scholarly digitized manuscripts of the world. The hope is to bring them under one system of classification so that they can quickly be searched and sorted no matter where they came from and where they now are stored. The world may always prefer cat gifs to ancient manuscripts, but the translation from parchment to pixels (像素) reminds us of the humanistic optimism with which the web came into the world, and shows that much of it was not misplaced at all. 76．Which would be the best title of the passage? A．The Impact of Digital Revolution Era B．The New Era of Traditional Manuscripts C．Accessibility of Old Manuscripts All Around the World D．Digital Revolution Brings Manuscripts To life 【2024·北京东城·二模】 You might not think that an AI capable of making music would stimulate your emotion, but others think differently, particularly those who gathered at Mexico City’s Symphony Hall in 2019 for Schubert’s Unfinished Symphony, which I finished using melodies generated by an AI. As the orchestra (管弦乐团) finished Schubert’s original work and began the music the AI and I had written, I could feel the crowd’s energy shift from astonishment to indignation and fear. They seemed afraid that an AI might be able to make emotional symphonic music. You can see their point: an AI that makes emotional music could affect the emotional lives of thousands or even millions of people in a small, but profound way, just like a human musician does. Positive and negative, people reacted very strongly to AI’s symphonic debut (首秀). Even though most people don’t believe that AI can create something enjoyable, they, at least partly, did enjoy the Unfinished Symphony. Enjoyment in music implies that there’s something in the music that the listener connects to, a perception of shared emotion. But, in the case of AI music, an emotion shared with who? AI, as of yet, has no emotions. So what is the meaning of music made without an emotional composer? The unsatisfying answer is that music has no objective meaning. A composer can decide how a piece of music sounds, but it’s the listener that decides what it means. No matter how it’s created, music doesn’t exist in a vacuum (真空) to the listener. The meaning we assign to music depends on its context — how the piece connects to other elements in our lives. Without context, music is like the results of a game whose rules have been lost. The context for a music is part of who you are. The music is emotional to you because you have the context to appreciate it. As it continues to evolve, AI music will develop its own context. Certainly, it’ll be different from human-made music. It’ll mix existing genres to create new ones; it’ll combine instruments that we wouldn’t think of combining. Its rules will be different. I’m now always asked the same question: “Who put the emotion in that music: you, the composer, or the AI?” But that’s not the question they really want to ask, though. There’s a deeper question that most people are too afraid to ask right now: “Are my emotions so simple that they can be maneuvered by a machine?” In my experience, this could be possible one day. If a modestly capable music AI in 2019 could stir up emotions of an audience, maybe AI can have a more powerful effect on our emotional lives than we’d like to admit. 12．Which would be the best title for the passage? A．Are Composers To Be Replaced? B．Would AI Music Be a Rising Trend? C．Could AI Make Music That Moves You? D．Was the Unfinished Symphony Successful? 【2024·北京·三模】 Is it possible to persuade mankind to live without war? War is an ancient institution, which has occurred ever since men were organized into units larger than the family. In the past human race managed to survive it. Why should it not continue to survive even if wars go on occurring from time to time? Moreover, people like war, and will feel frustrated without it. And without war there will be no adequate opportunity for heroism or self-sacrifice. Modem technology has changed this. Either man will abolish war, or war will abolish man. For the present, it is nuclear weapons that cause the most serious danger, but bacteriological or chemical weapons may, before long, offer an even greater threat. If we succeed in abolishing nuclear weapons, our work will not be done. It will never be done until we have succeeded in abolishing war. To do this, we need to persuade mankind to look upon international questions in a new way, not as contests of force, in which the victory goes to the side which is most skillful in killing people, but by arbitration (通过仲裁) in accordance with agreed principles of law. It is not easy to change very old mental habits, but this is what must be attempted. There are those who say that the adoption of this or that ideology (意识形态) would prevent war. I believe this to be a big error. All ideologies are based upon dogmatic (武断的) statements that are, at best, doubtful, and at worst, totally false. Their followers believe in them so fanatically that they are willing to go to war in support of them. The movement of world opinion during the past few years has been very largely such as we can welcome. It has become a commonplace that nuclear war must be avoided. Of course very difficult problems remain in the world, but the spirit in which they are being approached is a better one than it was some years ago. It has begun to be thought, even by the powerful men who decide whether we shall live or die, that negotiations should reach agreements even if both sides do not find these agreements wholly satisfactory. It has begun to be understood that the important conflict nowadays is not between different countries, but between man and the atom bomb. 16．Which would be the best title for the passage?

And 61 of them are not even supposed to be used in such products. “It’s not clear why the latter chemicals, which are not on lists of those authorized for use in food containers, are in such packaging.” says the study’s author Birgit Geueke. The study focused on a class of chemicals called perfluoroalkyl and polyfluoronlkyl substances (PFASs), which are sometimes called “forever chemicals” because they don’t break down readily in the environment or in the body. That’s because their characteristic carbon-fluorine bond is one of the strongest in nature. For decades, these substances have been used in a wide range of consumer products, from cookware to pesticide s to cosmetics, because they are proof against water and grease. Geueke and her team found a mismatch between what they detected in actual products and a database of PFAS chemicals authorized for use in food packaging. About 140 PFASs are known to be used in food packaging, but only seven of the 68 chemicals in the study were on this list. Geueke says it’s unclear how or why the other 61 chemicals turned up. David Andrews, a chemist and toxicologist at a nonprofit environmental advocacy organization, suggests it’s possible that unknown impurities emerged during the manufacturing of the authorized chemicals or that the authorized PFASs degrade over time. This class of chemicals includes many long-chain molecules, and they can break into shorter chains that are simply different types of PFASs. PFASs have been found in human blood and breast milk, drinking water, soil and other startling places around the world. Exposure to some of the most studied PFASs has been associated with cancer. reproductive problems and lessened responses to vaccines. “There’s an incredible body of scientific evidence linking PFAS chemicals to health harm,” says Andrews. Many countries are evaluating restrictions of PFASs in food packaging. Chemical industry representatives have advocated for dealing with PFASs as individual chemicals. Before publishing the new study. Scientific American reached out to the American Chemistry Council (ACC), a chemistry industry trade association, about it, but the organization did not reply. On its dedicated PFAS webpage. ACC notes that “all PFASs are not the same. Each individual chemical has its own unique properties and uses.” Andrews and Geueke both say the presence of unknown PFASs in food packaging is good reason to regulate these chemicals as a single class—a position shared with many other scientific experts and environmental protection groups. There are more than 12,000 known PFASs, and scientists don’t know much about most of them. “Only some PFASs have ever been tested for toxicity,” Geueke says, and “there are probably other ways to produce food packaging.” 14．Paragraph 3 is mainly about ______. A．the potential usage of the unknown impurities B．the authorization of food packaging chemicals C．the likely transforming process from PFASs into new chemicals D．the possible explanation for the presence of unauthorized PFASs 【答案】 14．D 【导语】这是一篇说明文。文章主要说明了世界各地的食品包装中至少含有68种“永久化学物质”，它们会渗入我们所吃的食物中。一项新的研究发现。其中61种甚至不应该用于此类产品。对此科学家进行了研究。 14．主旨大意题。根据第三段“Geueke and her team found a mismatch between what they detected in actual products and a database of PFAS chemicals authorized for use in food packaging.

Some Generation Z trend followers are now viewing it as a form of self-care, but doctors warn too much could be “sign of depression”. Are these extended breaks really wise for one’s mental health — or could they be a cause for concern? Dr. Ryan Sultan, a professor at Columbia University in New York, who treats many young people, called the bed rotting trend attractive. “In our culture today, with too much to do, too many expectations and too much productivity, many young individuals (个人) are feeling burned out and often aren’t getting enough sleep. It’s easy to see why taking time off to lie around is attractive,” Sultan said. “In many ways, this is beneficial. It’s a chance to get away from real-life problems and clear your head before returning to life in a better state of mind, ” he added. For the downside, however, he said a long-term need or desire for bed rotting could do harm to one’s physical health. Spending too many daytime hours in bed — awake or not — could destroy sleep schedules. Our brains are fine-tuned for sleep in darkness and alertness in light. Lying in bed half-asleep during the day will worsen sleep schedules — once that happens, it is a challenge to fix. It could also lead to blood pressure problems and obesity (肥胖). Long-term need or desire for bed rotting could also be a warning sign of depression, according to a mental health expert. Dr. Marc Siegel, professor of medicine at NYU Langone Medical Center and a Fox News medical contributor, agreed that while some downtime can be useful in terms of de-stressing and rejuvenation (更新), too much bed rotting is a bad health practice. In addition to increasing the risk of depression, it contributes to decreased motivation (动力) as well. Instead of bed rotting, Siegel recommends regular exercise as a better form of de-stressing. While the occasional lazy day can be beneficial, too much could have the opposite effect. If it happens every day, that’s a fairly sensitive test for depression. Those who lack the motivation to get out of bed could also try calling or texting a family member for support, socializing with close friends, finding a small task to complete, or reaching out to a medical professional for help. 8．What is the passage mainly talking about? A．Different opinions on how to become motivated. B．Main causes of the long-term need for bed rotting. C．Practical suggestions for young people to deal with stress. D．Possible problems from lying in bed for extended periods of time. 【答案】 8．D 【导语】这是一篇说明文。文章主要说明了年轻人喜欢躺尸来逃避压力，但专家指出长期需要或渴望躺尸 8．主旨大意题。根据第一段“Some Generation Z trend followers are now viewing it as a form of self-care, but doctors warn too much could be “sign of depression”. Are these extended breaks really wise for one’s mental health — or could they be a cause for concern?(一些Z世代的潮流追随者现在将其视为一种自我保健方式，但医生警告说，过度躺尸可能是“抑郁症的征兆”。这些延长的休息时间真的对一个人的心理健康有益吗？还是会引起人们的担忧？)”结合接下来的分析内容可知，文章主要说明了年轻人喜欢躺尸来逃避压力，但专家指出长期需要或渴望躺尸可能会损害一个人的身体健康。可知，这篇文章主要讲的是长时间躺在床上可能产生的问题。故选D。 题型03 标题归纳题 【题型诠释】 一、提问方式 The best title of the passage is ________.

There has been a debate about this possibility for decades. Recently two analyses have put the surprising cognitive (认知) abilities of dinosaurs — and their potential limitations — in a new light. In one study, Suzana Herculano-Houzel at Vanderbilt University calculated the likely number of neurons (神经细胞) in dinosaurs’ pallium, a brain structure that is responsible for advanced cognitive functions. Research suggests that it is the number of neurons in these areas, rather than the brain size, that indicates an animal’s cognitive potential. For example, despite having a very small head, birds have more densely packed brain cells than many mammals (哺乳动物) and so can possess roughly as many neurons as monkeys. The result is that some birds show great cognitive abilities, comparable to the smartest non-human mammals. And it is precisely birds, being the only surviving lineage (宗系) of dinosaurs, that are Herculano-Houzel’s foundation. By comparing the relationship between brain size, number of neurons and body size in numerous existing birds and available fossils of dinosaurs, Herculano-Houzel concludes that a large dinosaur such as T. rex could have housed two billion to three billion neurons in its pallium. If so, dinosaurs could have had the capacity for tool use and planning for the future. But neurons’ number may not be enough. For intelligence, brain architecture also matters. And this could be the weakness of dinosaurs, argues Anton Reiner from the University of Tennessee. Over 350 million years of separate evolution, mammals and dinosaurs found two rather different ways to organize cognitive functions. The mammalian neurons are organized in a relatively thin layer formed by compact columns. In each column, different parts can communicate with one another over short distances. In contrast, in the dinosaurs that survive today, namely birds, the organization is less compact. According to Reiner, expanding brain capabilities beyond a certain point could make the structure far more complex and less efficient than it is in humans. If this were the case, an increase in brain size would correspond to a greater distance between different parts of the brain, slowing down their communication. The issue remains open to debate. Herculano-Houzel and Reiner each published a paper with rejections to the other’s argument. Meanwhile, other scientists have entered the fight. For example, neurobiologist Giorgio Vallortigara assumes that speed in transmitting information between networks of neurons is probably one of dinosaurs’ strengths. Whatever the truth is, understanding how and if brain architecture imposes limits on the development of cognition could reveal much about the evolution of abilities and behaviors of various animals. Also, this debate may tell us more about our own species than about dinosaurs. 4．Which would be the best title for the passage? A．Are Dinosaurs Comparable to Humans in Intelligence? B．Are Dinosaurs with Bigger Brains the Ultimate Geniuses? C．How Smart Were Dinosaurs? New Studies Fuel the Debate D．Can Dinosaurs Outsmart Birds?

Here, norms (规范) were unwritten and rarely expressed clearly, but were well understood and taken to heart. Dishonest and violent behaviours were disapproved of; leadership, marriage and interactions with other groups were loosely governed by traditions. Conflict was often resolved in musical battles. Because arguing angrily leads to chaos, it was strongly discouraged. With life in the unforgiving Northern Canada being so demanding, the Inuit’s practical approach to morality made good sense. The similarity of moral virtues across cultures is striking, even though the relative ranking of the virtues may vary with a social group’s history and environment. Typically, cruelty and cheating are discouraged, while cooperation, humbleness and courage are praised. These universal norms far pre-date the concept of any moralising religion or written law. Instead, they are rooted in the similarity of basic human needs and our shared mechanisms for learning and problem solving. Our social instincts (本能) include the intense desire to belong. The approval of others is rewarding, while their disapproval is strongly disliked. These social emotions prepare our brains to shape our behaviour according to the norms and values of our family and our community. More generally, social instincts motivate us to learn how to behave in a socially complex world. The mechanism involves a repurposed reward system originally used to develop habits important for self-care. Our brains use the system to acquire behavioural patterns regarding safe routes home, efficient food gathering and dangers to avoid. Good habits save time, energy and sometimes your life. Good social habits do something similar in a social context. We learn to tell the truth, even when lying is self-serving; we help a grandparent even when it is inconvenient. We acquire what we call a sense of right and wrong. Social benefits are accompanied by social demands: we must get along, but not put up with too much. Hence self-discipline is advantageous. In humans, a greatly enlarged brain boosts self-control, just as it boosts problem-solving skills in the social as well as the physical world. These abilities are strengthened by our capacity for language, which allows social practices to develop in extremely unobvious ways. 34. Which would be the best title for this passage? A. Virtues: Bridges Across Cultures B. The Values of Self-discipline C. Brains: Walls Against Chaos D. The Roots of Morality 【答案】 34. D 【导语】本文是一篇说明文。主要围绕人类道德规范的起源进行讨论，介绍了早期人类道德准则的形成过程及其如何根植于人类基本需求及共同的社会学习和问题解决机制中。 【34题详解】 主旨大意题。根据第一段“Franz Boas’s description of Inuit (因纽特人) life in the 19th century illustrates the probable moral code of early humans.(弗朗兹·博厄斯对19世纪因纽特人生活的描述说明了早期人类可能的道德准则)”以及文章内容可知，本文围绕人类道德规范的起源进行讨论，主要介绍了早期人类道德准则的形成过程及其如何根植于人类基本需求及共同的社会学习和问题解决机制中，所以“道德的起源”适合作为文章标题。故选D项。 【2023北京卷】 What is life? Like most great questions, this one is easy to ask but difficult to answer. The reason is simple: we know of just one type of life and it’s challenging to do science with a sample size of one. The field of artificial life-called ALife for short — is the systematic attempt to spell out life’s fundamental principles. Many of these practitioners, so-called ALifers, think that somehow making life is the surest way to really understand what life is. So far no one has convincingly made artificial life. This track record makes ALife a ripe target for criticism, such as declarations of the field’s doubtful scientific value. Alan Smith, a complexity scientist, is tired of such complaints. Asking about “the point” of ALife might be, well, missing the point entirely, he says. “The existence of a living system is not about the use of anything.” Alan says. “Some people ask me, ‘So what’s the worth of artificial life?’ Do you ever think, ‘What is the worth of your grandmother?’” As much as many ALifers hate emphasizing their research’s applications, the attempts to create artificial life could have practical payoffs. Artificial intelligence may be considered ALife’s cousin in that researchers in both fields are enamored by a concept called open-ended evolution (演化). This is the capacity for a system to create essentially endless complexity, to be a sort of “novelty generator”. The only system known to exhibit this is Earth’s biosphere. If the field of ALife manages to reproduce life’s endless “creativity” in some virtual model, those same principles could give rise to truly inventive machines. Compared with the developments of Al, advances in ALife are harder to recognize. One reason is that ALife is a field in which the central concept — life itself — is undefined. The lack of agreement among ALifers doesn’t help either. The result is a diverse line of projects that each advance along their unique paths. For better or worse, ALife mirrors the very subject it studies. Its muddled (混乱的) progression is a striking parallel (平行线) to the evolutionary struggles that have shaped Earth biosphere. Undefined and uncontrolled, ALife drives its followers to repurpose old ideas and generated novelty. It may be, of course, that these characteristics aren’t in any way surprising or singular. They may apply universally to all acts of evolution. Ultimately ALife may be nothing special. But even this dismissal suggests something：perhaps, just like life itself throughout the universe, the rise of ALife will prove unavoidable. 34．Which would be the best title for the passage? A．Life Is Undefined. Can AI Be a Way Out? B．Life Evolves. Can AI Help ALife Evolve, Too? C．Life Is Undefined. Can ALife Be Defined One Day? D．Life Evolves. Can Attempts to Create ALife Evolve, Too? 【答案】 34．D 【导语】本文为说明文。文章主要探讨了ALife是否也在不断地进化的问题。 34．主旨大意题。根据最后一段“They may apply universally to all acts of evolution. Ultimately ALife may be nothing special. But even this dismissal suggests something: perhaps, just like life itself throughout the universe, the rise of ALife will prove unavoidable.(它们可能普遍适用于所有进化行为。最终，ALife可能没有什么特别的。但即使是这种否定也表明了一些事情：也许，就像整个宇宙中的生命本身一样，ALife的崛起将被证明是不可避免的)”结合文章主要探讨了ALife是否也在不断地进化。D选项“生命在进化。创造ALife的尝试也能进化吗？”是最合适的标题。故选D。 【2022年北京卷】 Quantum ( 量子 ) computers have been on my mind a lot lately. A friend has been sending me articles on how quantum computers might help solve some of the biggest challenges we face as humans. I’ve also had exchanges with two quantum-computing experts. One is computer scientist Chris Johnson who I see as someone who helps keep the field honest. The other is physicist Philip Taylor. For decades, quantum computing has been little more than a laboratory curiosity. Now, big tech companies have invested in quantum computing, as have many smaller ones. According to Business Weekly, quantum machines could help us “cure cancer, and even take steps to turn climate change in the opposite direction.” This is the sort of hype ( 炒作 ) that annoys Johnson. He worries that researchers are making promises they can’t keep. “What’s new,” Johnson wrote, “is that millions of dollars are now potentially available to quantum computing researchers.” As quantum computing attracts more attention and funding, researchers may mislead investors, journalists, the public and, worst of all, themselves about their work’s potential. If researchers can’t keep their promises, excitement might give way to doubt, disappointment and anger, Johnson warns. Lots of other technologies have gone through stages of excitement. But something about quantum computing makes it especially prone to hype, Johnson suggests, perhaps because “‘quantum’ stands for something cool you shouldn’t be able to understand.” And that brings me back to Taylor, who suggested that I read his book Q for Quantum. After I read the book, Taylor patiently answered my questions about it. He also answered my questions about PyQuantum, the firm he co-founded in 2016. Taylor shares Johnson’s concerns about hype, but he says those concerns do not apply to PyQuantum. The company, he says, is closer than any other firm “by a very large margin ( 幅度 )” to building a “useful” quantum computer, one that “solves an impactful problem that we would not have been able to solve otherwise.” He adds, “People will naturally discount my opinions, but I have spent a lot of time quantitatively comparing what we are doing with others.” Could PyQuantum really be leading all the competition “by a wide margin”, as Taylor claims? I don’t know. I’m certainly not going to advise my friend or anyone else to invest in quantum computers. But I trust Taylor, just as I trust Johnson. 34. Which would be the best title for the passage? A. Is Johnson More Competent Than Taylor? B. Is Quantum Computing Redefining Technology? C. Will Quantum Computers Ever Come into Being? D. Will Quantum Computing Ever Live Up to Its Hype? 【答案】34. D 34.【解析】 主旨大意题。根据第二自然段“Now, big tech companies have invested in quantum computing, as have many smaller ones. According to Business Weekly, quantum machines could help us “cure cancer, and even take steps to turn climate change in the opposite direction. This is the sort of hype ( 炒作 ) that annoys Johnson.”（ 现在，大型科技公司和许多小型公司都在量子计算领域进行了投资。据《商业周刊》报道，量子机器可以帮助我们“治愈癌症，甚至采取措施将气候变化转向相反的方向。这种炒作让约翰逊感到恼火。”）”以及最后一段“Could PyQuantum really be leading all the competition “by a wide margin”, as Taylor claims? I don’t know. I’m certainly not going to advise my friend or anyone else to invest in quantum computers.（PyQuantum真的能像泰勒所说的那样“以巨大的优势”领先所有竞争对手吗？我不知道。我当然不会建议我的朋友或其他人投资量子计算机。但我信任泰勒，就像我信任约翰逊一样。）”可知，本文主要论述了“量子计算真的会像它的宣传那样成功吗？”，计算机科学家克里斯·约翰逊和物理学家菲利普·泰勒分别阐明了自己的观点。所以短文的最佳标题为“量子计算真的会像它的宣传那样成功吗？”。故选D。 【2021年北京卷】 Early fifth-century philosopher St．Augustine famously wrote that he knew what time was unless someone asked him．Albert Einstein added another wrinkle when he theorized that time varies depending on where you measure it．Today's state-of-the-art atomic（原子的） clocks have proven Einstein right．Even advanced physics can't decisively tell us what time is, because the answer depends on the question you're asking． Forget about time as an absolute．What if，instead of considering time in terms of astronomy,we related time to ecology？What if we allowed environmental conditions to set the tempo（节奏） of human life？We're increasingly aware of the fact that we can't control Earth systems with engineering alone，and realizing that we need to moderate（调节）our actions if we hope to live in balance．What if our definition of time reflected that？ Recently，I conceptualized a new approach to timekeeping that's connected to circumstances on our planet，conditions that might change as a result of global warming．We're now building a clock at the Anchorage Museum that reflects the total flow of several major Alaskan rivers，which are sensitive to local and global environmental changes．We've programmed it to match an atomic clock if the waterways continue to flow at their present rate．If the rivers run faster in the future on average，the clock will get ahead of standard time．If they run slower，you'll see the opposite effect． The clock registers both short-term irregularities and long-term trends in river dynamics．It's a sort of observatory that reveals how the rivers are behaving from their own temporal frame（时间框架），and allows us to witness those changes on our smartwatches or phones．Anyone who opts to go on Alaska Mean River Time will live in harmony with the planet．Anyone who considers river time in relation to atomic time will encounter a major imbalance and may be motivated to counteract it by consuming less fuel or supporting greener policies． Even if this method of timekeeping is novel in its particulars，early agricultural societies also connected time to natural phenomena．In pre-Classical Greece，for instance，people“corrected”official calendars by shifting dates forward or backward to reflect the change of season．Temporal connection to the environment was vital to their survival．Likewise，river time and other timekeeping systems we're developing may encourage environmental awareness． When St．Augustine admitted his inability to define time， he highlighted one of time 's most noticeable qualities：Time becomes meaningful only in a defined context．Any timekeeping system is valid，and each is as praiseworthy as its purpose． 31 What is the main idea of Paragraph 1？ A. Timekeeping is increasingly related to nature． B. Everyone can define time on their own terms． C. The qualities of time vary with how you measure it． D. Time is a major concern of philosophers and scientists． 【答案】31. B 【分析】本文是议论文。文章通过讨论时间的定义，讲述了人们应该和大自然和谐相处，保护环境。 【31题详解】 主旨大意题。根据第一段最后一句“Even advanced physics can't decisively tell us what time is, because the answer depends on the question you're asking．(即使是先进的物理学也不能决定性地告诉我们时间是什么，因为答案取决于你要问的问题)”以及上文列举的哲学家St．Augustine和爱因斯坦对于时间的定义可推断，第一段主要讲述每个人都可以用自己的话来定义时间。故选B项。 【2020北京卷】 For the past five years, Paula Smith, a historian of science, has devoted herself to re-creating long-forgotten techniques. While doing research for her new book, she came across a 16th-century French manuscript（手稿）consisting of nearly 1,000 sets of instructions, covering subjects from tool making to finding the best sand. The author's intention remains as mysterious（神秘）as his name; he may have been simply taking notes for his own records. But Smith was struck mainly by the fact that she didn't truly grasp any of the skills the author described. "You simply can't get an understanding of that handwork by reading about it," she says. Though Smith did get her hands on the best sand, doing things the old-fashioned way isn't just about playing around with French mud. Reconstructing the work of the craftsmen（工匠）who lived centuries ago can reveal how they viewed the world, what objects filled their homes, and what went on in the workshops that produced them. It can even help solve present-day problems: In 2015, scientists discovered that a 10th-century English medicine for eve problems could kill a drug-resistant virus. The work has also brought insights for museums, Smith says. One must know how on object was made in order to preserve it. What's more, reconstructions might be the only way to know what treasures looked like before time wore them down. Scholars have seen this idea in practice with ancient Greek and Roman statues. These sculptures were painted a rainbow of striking colours. We can't appreciate these kinds of details without seeing works of art as they originally appeared-something Smith believes you can do only when you have a road map. Smith has put the manuscript's ideas into practice. Her final goal is to link the worlds of art and science back together: She believes that bringing the old recipes to life can help develop a kind of learning that highlights experimentation, teamwork, and problem solving. Back when science—then called “the new philosophy”—took shape, academics looked to craftsmen for help in understanding the natural world. Microscopes and telescopes were invented by way of artistic tinkering（修补）, as craftsmen experimented with glass to better bend light. If we can rediscover the values of hands-on experience and craftwork, Smith says, we can marry the best of our modern insights with the handiness of our ancestors. 41. Which would be the best title for this passage? A. Craftsmen Set the Trends for Artists B. Craftsmanship Leads to New Theories C. Craftsmanship Makes Better Scientists D. Craftsmen Reshape the Future of Science 【答案】 41. C 【分析】本文是一篇记叙文。主要讲述科学家Paula Smith致力于对古代手工技能的研究，认为科学家如果能够把古代的手工技能和现代的科学方法结合起来，就能够创造更大成就。 【41题详解】 主旨大意题。根据文章最后一段“If we can rediscover the values of hands-on experience and craftwork, Smith says, we can marry the best of our modern insights with the handiness of our ancestors. ”史密斯说，如果我们能重新发现实践经验和工艺的价值，我们就能将现代的最好见解与我们祖先的灵巧结合起来。由此可知本文的中心思想就在于如果科学家能把古代的手工技巧同现代的理论结合起来，就能够获得更多的成就。C选项Craftsmanship Makes Better Scientists工艺造就了更好的科学家，符合文章主题，适合做标题，故选C。 【点睛】标题猜测题。属于主旨大意题的一种，标题应位于文章之首，概括文章内容，点明文章主题。它可以是单词，短语，或句子。确定文章标题，第一，标题要与主题密切相关；其次，看标题是否能概括全文内容，不能只概括短文中的某些事实或细节；第三，标题范围不应太大或太小；最后，标题应新颖，概括性强并且精炼。小题4中C选项概括文中主旨大意，与主题密切相关，故选C。 【最新模考】 【2024·北京大兴·三模】 We now live in an age of instant images and emoji, when 10,000 copies of a picture can be spread around the world in seconds by sliding a finger half an inch across a phone screen. This would have been unbelievable and unimaginable 20 years ago. But it is in the world of hand-copied manuscripts (手稿) 1,000 years old or more that the digital revolution has had some of its most profound and obvious beneficial effects. What may have taken three years to write out can today be printed out in three seconds. There are now tens of thousands of once unique documents which have been digitized and placed online for anyone to access all around the world, and this is a vast, democratizing wonder. Take the Parker Library in Cambridge, which contains the scholarly works during the Reformation (宗教改革时期) and collected by Matthew Parker. It has been digitized in a project with Stanford University, and in 2018 the site was opened to all comers to browse after 10 years behind scholarly paywalls. What is astonishing is not just the texts themselves, but the pictures: the illuminations (插图) on some of the manuscripts show off the fertility and vividness of the medieval imagination. Digitized collections of these sorts cannot entirely substitute for real libraries. To touch with your own hand a parchment (羊皮纸) from a medieval monk is an experience no screen can offer, but it is one which must always be restricted to a lucky few. There are some things so old and fragile that even being looked at may damage them. The caves at Lascaux had to be closed to protect the paintings from the breath of tourists and replaced by a virtual display. Yet in some ways these copies are better than the originals. Reproductions of a high enough quality make obvious detail that’s invisible to the native eye. What’s more, digital collections can be gathered on one screen from across the globe. The International Dunhuang Project reunites on screen tens of thousands of Buddhist scrolls and artifacts in western China. What is possible with this one collection should fairly soon be possible with all the scholarly digitized manuscripts of the world. The hope is to bring them under one system of classification so that they can quickly be searched and sorted no matter where they came from and where they now are stored. The world may always prefer cat gifs to ancient manuscripts, but the translation from parchment to pixels (像素) reminds us of the humanistic optimism with which the web came into the world, and shows that much of it was not misplaced at all. 76．Which would be the best title of the passage? A．The Impact of Digital Revolution Era B．The New Era of Traditional Manuscripts C．Accessibility of Old Manuscripts All Around the World D．Digital Revolution Brings Manuscripts To life 【答案】 76．D 【导语】本文是一篇说明文。文章讲述了数字技术如何使古老手稿得以快速传播，以帕克图书馆为例，展示手稿数字化的成果。虽无法取代实物，数字化让更多人能接触珍贵文献，实现全球资源共享，保护脆弱文物，是人文研究领域的重大进步。 76．主旨大意题。通读全文，尤其是由文章第二段中“Take the Parker Library in Cambridge, which contains the scholarly works during the Reformation (宗教改革时期) and collected by Matthew Parker. It has been digitized in a project with Stanford University, and in 2018 the site was opened to all comers to browse after 10 years behind scholarly paywalls. What is astonishing is not just the texts themselves, but the pictures: the illuminations (插图) on some of the manuscripts show off the fertility and vividness of the medieval imagination. (以剑桥大学的帕克图书馆为例，里面有宗教改革时期的学术著作，由马修·帕克收藏。在斯坦福大学的一个项目中，该网站已被数字化，并于2018年向所有人开放，此前10年该网站一直处于学术收费墙之下。令人惊讶的不仅是文字本身，还有图片：一些手稿上的插图展示了中世纪想象力的丰富性和生动性)”可知，文章主要探讨了数字技术如何使古老的手稿以数字形式广泛传播，使全球范围内的访问成为可能，同时强调了这一过程对保护和研究古代文献的重要意义。由此可知，D选项“Digital Revolution Brings Manuscripts To life (数字革命使手稿栩栩如生)”适合作本文最佳标题。故选D。 【2024·北京东城·二模】 You might not think that an AI capable of making music would stimulate your emotion, but others think differently, particularly those who gathered at Mexico City’s Symphony Hall in 2019 for Schubert’s Unfinished Symphony, which I finished using melodies generated by an AI. As the orchestra (管弦乐团) finished Schubert’s original work and began the music the AI and I had written, I could feel the crowd’s energy shift from astonishment to indignation and fear. They seemed afraid that an AI might be able to make emotional symphonic music. You can see their point: an AI that makes emotional music could affect the emotional lives of thousands or even millions of people in a small, but profound way, just like a human musician does. Positive and negative, people reacted very strongly to AI’s symphonic debut (首秀). Even though most people don’t believe that AI can create something enjoyable, they, at least partly, did enjoy the Unfinished Symphony. Enjoyment in music implies that there’s something in the music that the listener connects to, a perception of shared emotion. But, in the case of AI music, an emotion shared with who? AI, as of yet, has no emotions. So what is the meaning of music made without an emotional composer? The unsatisfying answer is that music has no objective meaning. A composer can decide how a piece of music sounds, but it’s the listener that decides what it means. No matter how it’s created, music doesn’t exist in a vacuum (真空) to the listener. The meaning we assign to music depends on its context — how the piece connects to other elements in our lives. Without context, music is like the results of a game whose rules have been lost. The context for a music is part of who you are. The music is emotional to you because you have the context to appreciate it. As it continues to evolve, AI music will develop its own context. Certainly, it’ll be different from human-made music. It’ll mix existing genres to create new ones; it’ll combine instruments that we wouldn’t think of combining. Its rules will be different. I’m now always asked the same question: “Who put the emotion in that music: you, the composer, or the AI?” But that’s not the question they really want to ask, though. There’s a deeper question that most people are too afraid to ask right now: “Are my emotions so simple that they can be maneuvered by a machine?” In my experience, this could be possible one day. If a modestly capable music AI in 2019 could stir up emotions of an audience, maybe AI can have a more powerful effect on our emotional lives than we’d like to admit. 12．Which would be the best title for the passage? A．Are Composers To Be Replaced? B．Would AI Music Be a Rising Trend? C．Could AI Make Music That Moves You? D．Was the Unfinished Symphony Successful? 【答案】 12．C 【导语】这是一篇议论文。文章主要讨论了人工智能是否能创作出富含情感的音乐的问题，论述了作者对于音乐中情感的看法。 12．主旨大意题。根据第三段“Positive and negative, people reacted very strongly to AI’s symphonic debut (首秀). Even though most people don’t believe that AI can create something enjoyable, they, at least partly, did enjoy the Unfinished Symphony.(不管是正面还是负面，人们对AI的交响乐首演反应非常强烈。尽管大多数人不相信人工智能可以创造出令人愉快的东西，但他们（至少在一定程度上）确实喜欢《未完成的交响曲》)”结合文章主要讨论了人工智能是否能创作出富含情感的音乐的问题，论述了作者对于音乐中情感的看法。可知，C选项“人工智能能做出打动你的音乐吗？”最符合文章标题。故选C。 【2024·北京·三模】 Is it possible to persuade mankind to live without war? War is an ancient institution, which has occurred ever since men were organized into units larger than the family. In the past human race managed to survive it. Why should it not continue to survive even if wars go on occurring from time to time? Moreover, people like war, and will feel frustrated without it. And without war there will be no adequate opportunity for heroism or self-sacrifice. Modem technology has changed this. Either man will abolish war, or war will abolish man. For the present, it is nuclear weapons that cause the most serious danger, but bacteriological or chemical weapons may, before long, offer an even greater threat. If we succeed in abolishing nuclear weapons, our work will not be done. It will never be done until we have succeeded in abolishing war. To do this, we need to persuade mankind to look upon international questions in a new way, not as contests of force, in which the victory goes to the side which is most skillful in killing people, but by arbitration (通过仲裁) in accordance with agreed principles of law. It is not easy to change very old mental habits, but this is what must be attempted. There are those who say that the adoption of this or that ideology (意识形态) would prevent war. I believe this to be a big error. All ideologies are based upon dogmatic (武断的) statements that are, at best, doubtful, and at worst, totally false. Their followers believe in them so fanatically that they are willing to go to war in support of them. The movement of world opinion during the past few years has been very largely such as we can welcome. It has become a commonplace that nuclear war must be avoided. Of course very difficult problems remain in the world, but the spirit in which they are being approached is a better one than it was some years ago. It has begun to be thought, even by the powerful men who decide whether we shall live or die, that negotiations should reach agreements even if both sides do not find these agreements wholly satisfactory. It has begun to be understood that the important conflict nowadays is not between different countries, but between man and the atom bomb. 16．Which would be the best title for the passage? A．War or No War, That Is A Question B．Nuclear Weapons Bring the End of Human Race C．Towards a Future Without War: A Call for Global Arbitration D．From Ideology to Negotiation: A New Approach to International Conflicts 【答案】 16．C 【导语】本文是一篇议论文。在当前的国际形势之下，作者阐述人类应该以一种新的方式看待国际问题，而不是把它看作武力的较量。这种方式就是通过根据公认的法律原则进行仲裁。 16．主旨大意题。根据全文内容，特别是第二段“To do this, we need to persuade mankind to look upon international questions in a new way, not as contests of force, in which the victory goes to the side which is most skillful in killing people, but by arbitration (通过仲裁) in accordance with agreed principles of law .”（要做到这一点，我们需要说服人类以一种新的方式看待国际问题，而不是将其视为武力的较量，在这种较量中，胜利属于最善于杀人的一方，而是通过根据商定的法律原则进行仲裁。）可知，作者呼吁人们以新的方式看待国际问题，通过仲裁来解决问题，以此来废除战争，因此，C选项“Towards a Future Without War: A Call for Global Arbitration”（走向无战争的未来：全球仲裁的呼吁）最能概括全文内容。故选C。 原创精品资源学科网独家享有版权，侵权必究！11 学科网（北京）股份有限公司 $$
