（2022·天津·高考真题）Is it true that our brain alone is responsible fo human cognition(认知) What about our body Is it possible for thought and behavior to originate from somewhere other than our brain Psychologists who study Embodied Cognition(EC) ask similar questions. The EC theory suggests our body is also responsible for thinking or problem-solving. More precisely, the mind shapes the body and the body shapes the mind in equal measure.
If you think about it for a moment, it makes total sense. When you smell something good or hear amusing sounds, certain emotions are awakened. Think about how newborns use their senses to understand the world around them. They don’t have emotions so much as needs—they don’t feel sad, they’re just hungry and need food. Even unborn babies can feel their mothers’ heartbeats and this has a calming effect. In the real world，they cry when they’re cold and then get hugged. That way, they start to as-sociate being warm with being loved.
Understandably, theorists have been arguing for years and still disagree on whether the brain is the nerve centre that operates the rest of the body. Older Western philosophers and mainstream language researchers believe this is fact, while EC theorises that the brain and body are working together as an organic supercomputer, processing everything and forming your reactions.
Further studies have backed up the mind-body interaction. In one ex-periment, test subjects(实验对象) were asked to judge people after being handed a hot or a cold drink. They all made warm evaluations when their fingertips perceived warmth rather than coolness. And it works the other way too; in another study, subjects’ fingertip temperatures were measured after being“included” in or “rejected” from a group task. Those who were included felt physically warmer.
For further proof, we can look at the metaphors(比喻说法) that we use without even thinking. A kind and sympathetic person is frequently referred to as one with a soft heart and someone who is very strong and calm in difficult situations is often described as solid as a rock. And this kind of metaphorical use is common across languages.
Now that you have the knowledge of mind-body interaction, why not use it If you’re having a bad day,a warm cup of tea will give you a flash of pleasure. If you know you’re physically cold, warm up before making any interpersonal decisions.
1．According to the author, the significance of the EC theory lies in ________.

（2022·浙江·统考高考真题）Many people believe that working to the maximum is the secret to success, but research has found that moderation(适度) also gets results on the job.
In a study led by Ellen Langer of Harvard University, researchers asked people to translate sentences into a new a made-up language. Subjects who practiced the language moderately beforehand made fewer errors than those who practiced extensively or not at all. High levels of knowledge can make people too attached to traditional ways of viewing problems across fields the arts, sciences, and politics. High conscientiousness is related to lower job performance, especially in simple jobs where it doesn’t pay to be a perfectionist.
How long we stay on the clock and how we spend that time are under careful examination in many workplaces. The young banker who eats lunch at his desk is probably seen as a go-getter, while his colleagues who chat over a relaxed conference-room meal get dirty looks from the corner office. “People from cultures that value relationships more than ours does are shocked by the thought of eating alone in front of a computer”, says Art Markman, a professor of psychology at the University of Texas, Austin. Social interaction has been shown to lift mood(情绪) and get people thinking in new directions and in ways that could help improve any post-lunch effort.
Markman also promotes off-task time. “Part of being a good thinker is experiencing things that are seemingly unrelated to what you are working on at the moment but give you fresh ideas about your work,” he says. “Also, there is a lot of research showing that a positive mood leads to higher levels of productivity and creativity. So, when people do things to increase their life satisfaction, they also make themselves more effective at work.”
6．What does Ellen Langer’s study show
A．It is worthwhile to be a perfectionist B．Translation makes people knowledgeable.
C．Simpler jobs require greater caution. D．Moderate effort produces the best result.
7．The underlined word “go-getter” in paragraph 3 refers to someone Who_______.
A．is good at handling pressure B．works hard to become successful
C．a has a natural talent for his job. D．gets on well with his co-workers
8．What can be inferred from the last paragraph
A．A good thinker is able to inspire other people.
B．Experience unrelated to your job is useless.
C．A cheerful mood helps make a creative mind.
D．Focusing on what you do raises productivity.
9．What does the text seem to advocate
A．Middle-of-the-road work habits. B．Balance between work and family.
C．Long-standing cultural traditions. D．Harmony in the work environment.
（2022·北京·高考真题）“What would the world be if there were no hunger ” It’s a question that Professor Crystal would ask her students. They found it hard to answer, she wrote later, because imagining something that isn’t part of real life—and learning how to make it real—is a rare skill. It is taught to artists and engineers, but much less often to scientists. Crystal set out to change that, and helped to create a global movement. The result—an approach known as systems thinking—is now seen as essential in meeting global challenges.
Systems thinking is crucial to achieving targets such as zero hunger and better nutrition because it requires considering the way in which food is produced, processed, delivered and consumed, and looking at how those things intersect (交叉 ) with human health, the environment, economics and society. According to systems thinking, changing the food system—or any other network—requires three things to happen. First, researchers need to identify all the players in that system; second, they must work out how they relate to each other; and third, they need to understand and quantify the impact of those relationships on each other and on those outside the system.
Take nutrition. In the latest UN report on global food security, the number of undernourished (营养不良 )people in the world has been rising, despite great advances in nutrition science. Tracking of 150 biochemicals in food has been important in revealing the relationships between calories, sugar, fat and the occurrence of common diseases. But using machine learning and artificial intelligence, some scientists propose that human diets consist of at least 26,000 biochemicals—and that the vast majority are not known. This shows that we have some way to travel before achieving the first objective of systems thinking - which,in this example, is to identify more constituent parts of the nutrition system.
A systems approach to creating change is also built on the assumption that everyone in the system has equal power. But as some researchers find, the food system is not an equal one. A good way to redress (修正 ) such power imbalance is for more universities to do what Crystal did and teach students how to think using a systems approach.
More researchers, policymakers and representatives from the food industry must learn to look beyond their direct lines of responsibility and adopt a systems approach. Crystal knew that visions alone don’t produce results, but concluded that “we’ll never produce results that we can’t envision”.
10．The author uses the question underlined in Paragraph 1 to ________.
A．illustrate an argument B．highlight an opinion
C．introduce the topic D．predict the ending
11．What can be inferred about the field of nutrition
A．The first objective of systems thinking hasn’t been achieved.
B．The relationships among players have been clarified.
C．Machine learning can solve the nutrition problem.
D．The impact of nutrition cannot be quantified.
12．As for systems thinking, which would the author agree with
A．It may be used to justify power imbalance.
B．It can be applied to tackle challenges.
C．It helps to prove why hunger exists.
D．It goes beyond human imagination.
（2022·北京·高考真题）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.
13．Regarding Johnson’s concerns, the author feels ________.
A．sympathetic B．unconcerned C．doubtful D．excited
14．What leads to Taylor’s optimism about quantum computing
A．His dominance in physics. B．The competition in the field.
C．His confidence in PyQuantum. D．The investment of tech companies.
15．What does the underlined word “prone” in Paragraph 3 most probably mean
A．Open. B．Cool. C．Useful. D．Resistant.
16．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
（2022·全国·统考高考真题）Over the last seven years, most states have banned texting by drivers, and public service campaigns have tried a wide range of methods to persuade people to put down their phones when they are behind the wheel.
Yet the problem, by just about any measure, appears to be getting worse. Americans are still texting while driving, as well as using social networks and taking photos. Road accidents, which had fallen for years, are now rising sharply.
That is partly because people are driving more, but Mark Rosekind, the chief of the National Highway Traffic Safety Administration, said distracted（分心）driving was "only increasing, unfortunately."
"Big change requires big ideas." he said in a speech last month, referring broadly to the need to improve road safety. So to try to change a distinctly modern behavior, lawmakers and public health experts are reaching back to an old approach: They want to treat distracted driving like drunk driving.
An idea from lawmakers in New York is to give police officers a new device called the Textalyzer. It would work like this: An officer arriving at the scene of a crash could ask for the phones of the drivers and use the Textalyzer to check in the operating system for recent activity. The technology could determine whether a driver had just texted, emailed or done anything else that is not allowed under New York's hands-free driving laws.
"We need something on the books that can change people's behavior,” said Félix W. Ortiz, who pushed for the state's 2001 ban on hand-held devices by drivers. If the Textalyzer bill becomes law, he said, "people are going to be more afraid to put their hands on the cell phone."
17．Which of the following best describes the ban on drivers' texting in the US
A．Ineffective. B．Unnecessary.
C．Inconsistent. D．Unfair.
18．What can the Textalyzer help a police officer find out
A．Where a driver came from. B．Whether a driver used their phone.
C．How fast a driver was going. D．When a driver arrived at the scene.
19．What does the underlined word "something" in the last paragraph refer to
A．Advice. B．Data. C．Tests. D．Laws.
20．What is a suitable title for the text
A．To Drive or Not to Drive Think Before You Start
B．Texting and Driving Watch Out for the Textalyzer
C．New York Banning Hand-Held Devices by Drivers.
D．The Next Generation Cell Phone: The Textalyzer-
（2022·全国·高考真题）Human speech contains more than 2,000 different sounds, from the common “m” and “a” to the rare clicks of some southern African languages. But why are certain sounds more common than others A ground-breaking, five-year study shows that diet-related changes in human bite led to new speech sounds that are now found in half the world’s languages.
More than 30 years ago, the scholar Charles Hockett noted that speech sounds called labiodentals, such as “f” and “v”, were more common in the languages of societies that ate softer foods. Now a team of researchers led by Damián Blasi at the University of Zurich, Switzerland, has found how and why this trend arose.
They discovered that the upper and lower front teeth of ancient human adults were aligned (对齐), making it hard to produce labiodentals, which are formed by touching the lower lip to the upper teeth. Later, our jaws changed to an overbite structure (结构), making it easier to produce such sounds.
The team showed that this change in bite was connected with the development of agriculture in the Neolithic period. Food became easier to chew at this point. The jawbone didn’t have to do as much work and so didn’t grow to be so large.
Analyses of a language database also confirmed that there was a global change in the sound of world languages after the Neolithic age, with the use of “f” and “v” increasing remarkably during the last few thousand years. These sounds are still not found in the languages of many hunter-gatherer people today.
This research overturns the popular view that all human speech sounds were present when human beings evolved around 300,000 years ago. “The set of speech sounds we use has not necessarily remained stable since the appearance of human beings, but rather the huge variety of speech sounds that we find today is the product of a complex interplay of things like biological change and cultural evolution,” said Steven Moran, a member of the research team.
21．Which aspect of the human speech sound does Damián Blasi’s research focus on
A．Its variety. B．Its distribution. C．Its quantity. D．Its development.
22．Why was it difficult for ancient human adults to produce labiodentals
A．They had fewer upper teeth than lower teeth.
B．They could not open and close their lips easily.
C．Their jaws were not conveniently structured.
D．Their lower front teeth were not large enough.
23．What is paragraph 5 mainly about
A．Supporting evidence for the research results.
B．Potential application of the research findings.
C．A further explanation of the research methods.
D．A reasonable doubt about the research process.
24．What does Steven Moran say about the set of human speech sounds
A．It is key to effective communication. B．It contributes much to cultural diversity.
C．It is a complex and dynamic system. D．It drives the evolution of human beings.
（2022·全国·高考真题）Can a small group of drones (无人机) guarantee the safety and reliability of railways and, at the same time, help railway operators save billions of euros each year That is the very likely future of applying today’s “eyes in the sky” technology to make sure that the millions of kilometres of rail tracks and infrastructure (基础设施) worldwide are safe for trains on a 24/7 basis.
Drones are already being used to examine high-tension electrical lines. They could do precisely the same thing to inspect railway lines and other vital aspects of rail infrastructure such as the correct position of railway tracks and switching points. The more regularly they can be inspected, the more railway safety, reliability and on-time performance will be improved. Costs would be cut and operations would be more efficient (高效) across the board.
That includes huge savings in maintenance costs and better protection of railway personnel safety. It is calculated that European railways alone spend approximately 20 billion euros a year on maintenance, including sending maintenance staff, often at night, to inspect and repair the rail infrastructure. That can be dangerous work that could be avoided with drones assisting the crews’ efforts.
By using the latest technologies, drones could also start providing higher-value services for railways, detecting faults in the rail or switches, before they can cause any safety problems. To perform these tasks, drones for rail don’t need to be flying overhead. Engineers are now working on a new concept: the rail drones of the future. They will be moving on the track ahead of the train, and programmed to run autonomously. Very small drones with advanced sensors and AI and travelling ahead of the train could guide it like a co-pilot. With their ability to see ahead, they could signal any problem, so that fast-moving trains would be able to react in time.
25．What makes the application of drones to rail lines possible
A．The use of drones in checking on power lines. B．Drones’ ability to work at high altitudes.
C．The reduction of cost in designing drones. D．Drones’ reliable performance in remote areas.
26．What does “maintenance” underlined in paragraph 3 refer to
A．Personnel safety. B．Assistance from drones.
C．Inspection and repair. D．Construction of infrastructure.
27．What function is expected of the rail drones
A．To provide early warning. B．To make trains run automatically.
C．To earn profits for the crews. D．To accelerate transportation.
28．Which is the most suitable title for the text
A．What Faults Can Be Detected with Drones
B．How Production of Drones Can Be Expanded
C．What Difficulty Drone Development Will Face
D．How Drones Will Change the Future of Railways
（2022·浙江·统考高考真题）The United States rose to global power on the strength of its technology, and the lifeblood that technology has long been electricity. By providing long-distance communication and energy, electricity created the modem world. Yet properly understood, the age of electricity is merely the second stage in the age of steam, which began a century earlier.
"It is curious that no one has put together a history of both the steam and electric revolutions." writes Maury Klein in his book The Power Makers, Steam, Electricity, and the Men Invented Modern America. Klein, a noted historian of technology, spins a narrative so lively that at times it reads like a novel.
The story begins in the last years of the 18th century in Scotland, where Watt perfected "the machine that changed the world". Klein writes, "America did not invent the steam engine, but once they grasped its passwords they put it to more uses than anyone else. "
Meanwhile, over the course of 19th century, electricity went from mere curiosity to a basic necessity. Morse invented a code for sending messages over an electromagnetic circuit. Bell then gave the telegraph a voice. Edison perfected an incandescent bulls that brought electric light into the American home.
Most importantly, Edison realized that success depended on mass electrification, which he showed in New York City. With help from Tesla, Westinghouse's firm developed a system using alternating current, which soon became the major forms of power delivery.
To frame his story, Klein creates the character of Ned, a fictional witness to the progress brought about by the steams and electric revolutions in America during one man's lifetime. It's a technique that helps turn a long narrative into an interesting one.
29．What is Klein's understanding of the age of electricity
A．It is closely linked to the steam age.
B．It began earlier than proper thought.
C．It is a little-studied period of history.
D．It will come to an end sooner or later.
30．What can be inferred about Ned
A．He was born in New York City. B．He wrote many increasing stories,
C．He created an electricity company. D．He lived mainly in the 19th century.
31．What is the text
A．A biography. B．A book review. C．A short story. D．A science report.
（2021·全国·统考高考真题）An Australian professor is developing a robot to monitor the health of grazing cattle, a development that could bring big changes to a profession that's relied largely on a low-tech approach for decades but is facing a labor shortage.
Salah Sukkarieh, a professor at the University of Sydney, sees robots as necessary given how cattlemen are aging. He is building a four-wheeled robot that will run on solar and electric power. It will use cameras and sensors to monitor the animals. A computer system will analyze the video to determine whether a cow is sick. Radio tags (标签) on the animals will measure temperature changes. The quality of grassland will be tracked by monitoring the shape, color and texture (质地) of grass. That way, cattlemen will know whether they need to move their cattle to another field for nutrition purposes.
Machines have largely taken over planting, watering and harvesting crops such as com and wheat, but the monitoring of cattle has gone through fewer changes.
For Texas cattleman Pete Bonds, it's increasingly difficult to find workers interested in watching cattle. But Bonds doesn't believe a robot is right for the job. Years of experience in the industry - and failed attempts to use technology - have convinced him that the best way to check cattle is with a man on a horse. Bonds, who bought his first cattle almost 50 years ago, still has each of his cowboys inspect 300 or 400 cattle daily and look for signs that an animal is getting sick.
Other cattlemen see more promise in robots. Michael Kelsey Paris, vice president of the Oklahoma Cattlemen's Association, said a robot could be extremely useful given rising concerns about cattle theft. Cattle tend to be kept in remote places and their value has risen, making them appealing targets.
32．What is a problem with the cattle-raising industry
A．Soil pollution. B．Lack of workers.
C．Aging machines. D．Low profitability.
33．What will Sukkarieh's robot be able to do
A．Monitor the quality of grass. B．Cure the diseased cattle.
C．Move cattle to another field. D．Predict weather changes.
34．Why does Pete Bonds still hire cowboys to watch cattle
A．He wants to help them earn a living. B．He thinks men can do the job better.
C．He is inexperienced in using robots. D．He enjoys the traditional way of life.
35．How may robots help with cattle watching according to Michael Kelsey
A．Increase the value of cattle. B．Bring down the cost of labor.
C．Make the job more appealing. D．Keep cattle from being stolen.
（2021·天津·高考真题）In the fictional worlds of film and TV, artificial intelligence （Al） has been described as so advanced that it is indistinguishable from humans. But what if we're actually getting closer to a world where Al is capable of thinking and feeling
Tech company UneeQ is heading for its "digital humans", which appear life like on the screen not only in terms of language, but also because of facial movements: raised eyebrows, a smile, even a nod. They look close to a human, but not quite.
What lies beneath UneeQ9 s digital humans Their 3D faces are modeled on actual human features. Speech recognition enables them to understand what a person is saying, and natural language processing is used to work out a response. Meanwhile, another Al company, Soul Machines, is taking a more biological approach, with a "digital brain", that imitates aspects of the human brain to adjust the emotions "felt" and "expressed" by its "digital people".
Shiwali Mohan, an Al scientist at the Palo Research Center, is skeptical of these digital beings. "They're humanlike in their looks and the way they sound, but that in itself is not being human," she says. "Human qualities also involve how you think, how you approach problems, and how you break them down; and that takes a lot of algorithmic (算 法)design. Designing for human-level intelligence is a different attempt than designing images that behave like humans." She then continues, “If something looks like a human, we have high expectations of them, but they might behave differently in ways that humans just instinctively (直觉地)know how other humans react.
Yet the demand is there, with UneeQ seeing high adoption of its digital employees across the financial, health care, and commercial sectors （行业）. "Unless these sectors make their business models much more efficient digitally, they might be left behind," says Chetan Dube, UneeQ9s CEO.
Some other companies are taking their digital beings a step further, enabling organizations and individuals to create digital humans themselves using free-access platforms they provide. "The biggest motivation for such platforms is to popularize Al," Dube says.
Mohan is cautious about this approach, yet she supports the purpose behind these digital beings and is optimistic about where they are headed. "As we develop more advanced Al technology, we would then have to use new ways of communicating with that technology,she says. "'Hopefully, all of that is designed to support humans in their goals."
36．According to Para. 2, in what respect（s） do UneeQ9s "digital humans" resemble human beings
A．In the way they move around.
B．In the way they act and react.
C．In observation and analysis.
D．In speech and facial expressions.
37．Soul Machines’digital brain is a technological breakthrough because it .
A．leams to make proper emotional responses
B．tends to imitate human beings' tone vividly
C．recognizes the speech sounds it receives
D．processes the natural language it hears
38．In Mohan's opinion, what human quality is lacking in digital beings
A．Calculating brain.
B．Language skills.
C．Instinctive judgements.
D．Problem-solving ability.
39．What makes many sectors employ digital humans
A．The fear of falling behind in efficiency.
B．The urgency to promote e-commerce.
C．The wish to spread digital technology.
D．The need to upgrade the health care system.
40．What does Mohan think of the future of digital beings
A．It's well planned.
B．It is promising.
C．It is uncertain.
D．It's quite hopeless.
（2021·全国·高考真题）If you ever get the impression that your dog can “tell” whether you look content or annoyed, you may be onto something. Dogs may indeed be able to distinguish between happy and angry human faces, according to a new study.
Researchers trained a group of 11 dogs to distinguish between images (图像) of the same person making either a happy or an angry face. During the training stage, each dog was shown only the upper half or the lower half of the person’s face. The researchers then tested the dogs’ ability to distinguish between human facial expressions by showing them the other half of the person’s face on images totally different from the ones used in training. The researchers found that the dogs were able to pick the angry or happy face by touching a picture of it with their noses more often than one would expect by random chance.
The study showed the animals had figured out how to apply what they learned about human faces during training to new faces in the testing stage. “We can rule out that the dogs simply distinguish between the pictures based on a simple cue, such as the sight of teeth,” said study author Corsin Muller. “Instead, our results suggest that the successful dogs realized that a smiling mouth means the same thing as smiling eyes, and the same rule applies to an angry mouth having the same meaning as angry eyes.”
“With our study, we think we can now confidently conclude that at least some dogs can distinguish human facial expressions,” Muller told Live Science.
At this point, it is not clear why dogs seem to be equipped with the ability to recognize different facial expressions in humans. “To us, the most likely explanation appears to be that the basis lies in their living with humans, which gives them a lot of exposure to human facial expressions, and this exposure has provided them with many chances to learn to distinguish between them,” Muller said.
41．The new study focused on whether dogs can_________.
A．distinguish shapes B．make sense of human faces
C．feel happy or angry D．communicate with each other
42．What can we learn about the study from paragraph 2
A．Researchers tested the dogs in random order.
B．Diverse methods were adopted during training.
C．Pictures used in the two stages were different
D．The dogs were photographed before the lest.
43．What is the last paragraph mainly about
A．A suggestion for future studies. B．A possible reason for the study findings.
C．A major limitation of the study D．An explanation of the research method.
（2021·全国·高考真题） Popularization has in some cases changed the original meaning of emotional (情感的) intelligence. Many people now misunderstand emotional intelligence as almost everything desirable in a person's makeup that cannot be measured by an IQ test, such as character, motivation, confidence, mental stability, optimism and “people skills.” Research has shown that emotional skills may contribute to some of these qualities, but most of them move far beyond skill-based emotional intelligence.
We prefer to describe emotional intelligence as a specific set of skills that can be used for either good or bad purposes. The ability to accurately understand how others are feeling may be used by a doctor to find how best to help her patients, while a cheater might use it to control potential victims. Being emotionally intelligent does not necessarily make one a moral person.
Although popular beliefs regarding emotional intelligence run far ahead of what research can reasonably support, the overall effects of the publicity have been more beneficial than harmful. The most positive aspect of this popularization is a new and much needed emphasis (重视) on emotion by employers, educators and others interested in promoting social well-being. The popularization of emotional intelligence has helped both the public and researchers re-evaluate the functionality of emotions and how they serve people adaptively in everyday life.
Although the continuing popular appeal of emotional intelligence is desirable, we hope that such attention will excite a greater interest in the scientific and scholarly study of emotion. It is our hope that in coming decades, advances in science will offer new perspectives (视角) from which to study how people manage their lives. Emotional intelligence, with its focus on both head and heart, may serve to point us in the right direction.
44．What is a common misunderstanding of emotional intelligence
A．It can be measured by an IQ test. B．It helps to exercise a person’s mind.
C．It includes a set of emotional skills. D．It refers to a person’s positive qualities.
45．Why does the author mention “doctor” and “cheater” in paragraph 2
A．To explain a rule. B．To clarify a concept.
C．To present a fact. D．To make a prediction.
46．What is the author’s attitude to the popularization of emotional intelligence
A．Favorable. B．Intolerant.
C．Doubtful. D．Unclear.
47．What does the last paragraph mainly talk about concerning emotional intelligence
A．Its appeal to the public. B．Expectations for future studies.
C．Its practical application. D．Scientists with new perspectives.
（2021·全国·高考真题）During an interview for one of my books, my interviewer said something I still think about often. Annoyed by the level of distraction (干扰) in his open office, he said, “That’s why I have a membership at the coworking space across the street — so I can focus”. His comment struck me as strange. After all, coworking spaces also typically use an open office layout (布局). But I recently came across a study that shows why his approach works.
The researchers examined various levels of noise on participants as they completed tests of creative thinking. They were randomly divided into four groups and exposed to various noise levels in the background, from total silence to 50 decibels (分贝), 70 decibels, and 85 decibels. The differences between most of the groups were statistically insignificant; however, the participants in the 70 decibels group — those exposed to a level of noise similar to background chatter in a coffee shop — significantly outperformed the other groups. Since the effects were small, this may suggest that our creative thinking does not differ that much in response to total silence and 85 decibels of background noise.
But since the results at 70 decibels were significant, the study also suggests that the right level of background noise — not too loud and not total silence — may actually improve one’s creative thinking ability. The right level of background noise may interrupt our normal patterns of thinking just enough to allow our imaginations to wander, without making it impossible to focus. This kind of “distracted focus” appears to be the best state for working on creative tasks.
So why do so many of us hate our open offices The problem may be that, in our offices, we can’t stop ourselves from getting drawn into others’ conversations while we’re trying to focus. Indeed, the researchers found that face-to-face interactions and conversations affect the creative process, and yet a coworking space or a coffee shop provides a certain level of noise while also providing freedom from interruptions.
48．Why does the interviewer prefer a coworking space
A．It helps him concentrate. B．It blocks out background noise.
C．It has a pleasant atmosphere. D．It encourages face-to-face interactions.
49．Which level of background noise may promote creative thinking ability
A．Total silence. B．50 decibels C．70 decibels. D．85 decibels.
50．What makes an open office unwelcome to many people
A．Personal privacy unprotected. B．Limited working space.
C．Restrictions on group discussion. D．Constant interruptions.
51．What can we infer about the author from the text
A．He’s a news reporter.
B．He’s an office manager.
C．He’s a professional designer.
D．He’s a published writer.
（2021·浙江·统考高考真题）Researchers say they have translated the meaning of gestures that wild chimpanzees (黑猩猩) use to communicate. They say wild chimps communicate 19 specific messages to one another with a “vocabulary” of 66 gestures. The scientists discovered this by following and filming groups of chimps in Uganda, and examining more than 5,000 incidents of these meaningful exchanges.
Dr Catherine Hobaiter, who led the research, said that this was the only form of intentional communication to be recorded in the animal kingdom. Only humans and chimps, she said, had a system of communication where they deliberately sent a message to another group member.
“That’s what’s so amazing about chimp gestures,” she said. “They’re the only thing that looks like human language in that respect.”
Although previous research has shown that apes and monkeys can understand complex information from another animal’s call, the animals do not appear to use their voices intentionally to communicate messages. This was a significant difference between calls and gestures, Dr Hobaiter said.
Chimps will check to see if they have the attention of the animal with which they wish to communicate. In one case, a mother presents her foot to her crying baby, signaling: “Climb on me.” The youngster immediately jumps on to its mothers back and they travel off together. “The big message from this study is that there is another species (物种) out there. that is meaningful in its communication, so that’s not unique to humans,” said Dr Hobaiter.
Dr Susanne Shultz, an evolutionary biologist from the University of Manchester, said the study was praiseworthy in seeking to enrich our knowledge of the evolution of human language. But, she added, the results were “a little disappointing”.
“The vagueness of the gesture meanings suggests either that the chimps have little to communicate, or we are still missing a lot of the information contained in their gestures and actions,” she said. “Moreover, the meanings seem to not go beyond what other animal convey with non-verbal communication. So, it seems the gulf remains. ”
52．What do chimps and humans have in common according to Dr Hobaiter
A．Memorizing specific words. B．Understanding complex information.
C．Using voices to communicate. D．Communicating messages on purpose.
53．What did Dr Shultz think of the study
A．It was well designed but poorly conducted.
B．It was a good try but the findings were limited.
C．It was inspiring but the evidence was unreliable.
D．It was a failure but the methods deserved praise.
54．What does the underlined word “gulf” in the last paragraph mean
A．Difference. B．Conflict. C．Balance. D．Connection.
55．Which of the following is the best title for the text
A．Chimpanzee behaviour study achieved a breakthrough
B．Chimpanzees developed specific communication skills
C．Chimpanzees: the smartest species in the animal kingdom
D．Chimpanzee language: communication gestures translated

（2020·北京·高考真题）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 an 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.
59．How did Smith, feel after reading the French manuscript
A．Confused about the technical terms.
B．Impressed with its detailed instructions.
C．Discouraged by its complex structure.
D．Shocked for her own lack of hand skills.
60．According to Smith, the reconstruction work is done mainly to _____________.
A．restore old workshops B．understand the craftsmen
C．improve visual effects D．inspire the philosophers
61．Why does the author mention museums
A．To reveal the beauty of ancient objects.
B．To present the findings of old science.
C．To highlight the importance of antiques.
D．To emphasise the values of hand skills.
62．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
（2020·北京·高考真题）Certain forms of AI are indeed becoming ubiquitous. For example, algorithms (算法) carry out huge volumes of trading on our financial markets, self-driving cars are appearing on city streets, and our smartphones are translating from one language into another. These systems are sometimes faster and more perceptive than we humans are. But so far that is only true for the specific tasks for which the systems have been designed. That is something that some AI developers are now eager to change.
Some of today’s AI pioneers want to move on from today’s world of “weak” or “narrow” AI, to create “strong” or “full” AI, or what is often called artificial general intelligence (AGI). In some respects, today’s powerful computing machines already make our brains look weak. AGI could, its advocates say, work for us around the clock, and drawing on all available data, could suggest solutions to many problems. DM, a company focused on the development of AGI, has an ambition to “solve intelligence”. “If we’re successful,” their mission statement reads, “we believe this will be one of the most important and widely beneficial scientific advances ever made.”
Since the early days of AI, imagination has outpaced what is possible or even probable. In 1965, an imaginative mathematician called Irving Good predicted the eventual creation of an “ultra-intelligent machine…that can far surpass all the intellectual (智力的) activities of any man, however clever.” Good went on to suggest that “the first ultra-intelligent machine” could be “the last invention that man need ever make.”
Fears about the appearance of bad, powerful, man-made intelligent machines have been reinforced (强化) by many works of fiction — Mary Shelley’s Frankenstein and the Terminator film series, for example. But if AI does eventually prove to be our downfall, it is unlikely to be at the hands of human-shaped forms like these, with recognisably human motivations such as aggression (敌对行为). Instead, I agree with Oxford University philosopher Nick Bostrom, who believes that the heaviest risks from AGI do not come from a decision to turn against mankind but rather from a dogged pursuit of set objectives at the expense of everything else.
The promise and danger of true AGI are great. But all of today’s excited discussion about these possibilities presupposes the fact that we will be able to build these systems. And, having spoken to many of the world’s foremost AI researchers, I believe there is good reason to doubt that we will see AGI any time soon, if ever.
63．What does the underlined word “ubiquitous” in Paragraph I probably mean
A．Enormous in quantity. B．Changeable daily.
C．Stable in quality. D．Present everywhere.
64．What could AGI do for us, according to its supporters
A．Help to tackle problems. B．Make brains more active.
C．Benefit ambitious people. D．Set up powerful databases.
65．As for Irving Good’s opinion on ultra-intelligent machines, the author is ____________.
A．supportive B．disapproving
C．fearful D．uncertain
66．What can be inferred about AGI from the passage
A．It may be only a dream.
B．It will come into being soon.
C．It will be controlled by humans.
D．It may be more dangerous than ever.
（2020·江苏·高考真题）For those who can stomach it, working out before breakfast may be more beneficial for health than eating first, according to a study of meal timing and physical activity.
Athletes and scientists have long known that meal timing affects performance. However, far less has been known about how meal timing and exercise might affect general health.
To find out, British scientists conducted a study. They first found 10 overweight and inactive but otherwise healthy young men, whose lifestyles are, for better and worse, representative of those of most of us. They tested the men’s fitness and resting metabolic (新陈代谢的) rates and took samples (样品) of their blood and fat tissue.
Then, on two separate morning visits to the scientists’ lab, each man walked for an hour at an average speed that, in theory, should allow his body to rely mainly on fat for fuel. Before one of these workouts, the men skipped breakfast, meaning that they exercised on a completely empty stomach after a long overnight fast (禁食). On the other occasion, they ate a rich morning meal about two hours before they started walking.
Just before and an hour after each workout, the scientists took additional samples of the men’s blood and fat tissue.
Then they compared the samples. There were considerable differences. Most obviously, the men displayed lower blood sugar levels at the start of their workouts when they had skipped breakfast than when they had eaten. As a result, they burned more fat during walks on an empty stomach than when they had eaten first. On the other hand, they burned slightly more calories (卡路里), on average, during the workout after breakfast than after fasting.
But it was the effects deep within the fat cells that may have been the most significant, the researchers found. Multiple genes behaved differently, depending on whether someone had eaten or not before walking. Many of these genes produce proteins (蛋白质) that can improve blood sugar regulation and insulin (胰岛素) levels throughout the body and so are associated with improved metabolic health. These genes were much more active when the men had fasted before exercise than when they had breakfasted.
The implication of these results is that to gain the greatest health benefits from exercise, it may be wise to skip eating first.
67．The underlined expression “stomach it” in Paragraph 1 most probably means “______”.
A．digest the meal easily B．manage without breakfast
C．decide wisely what to eat D．eat whatever is offered
68．Why were the 10 people chosen for the experiment
A．Their lifestyles were typical of ordinary people.
B．Their lack of exercise led to overweight.
C．They could walk at an average speed.
D．They had slow metabolic rates.
69．What happened to those who ate breakfast before exercise
A．They successfully lost weight. B．They consumed a bit more calories.
C．They burned more fat on average. D．They displayed higher insulin levels.
70．What could be learned from the research
A．A workout after breakfast improves gene performances.
B．Too much workout often slows metabolic rates.
C．Lifestyle is not as important as morning exercise.
D．Physical exercise before breakfast is better for health.
（2020·天津·高考真题）For people, who are interested in sound, the field of sound technology is definitely making noise. In the past, sound engineers worked in the back rooms of recording studios, but many of today’s sound professionals are sharing their knowledge and experience with professionals in other fields to create new products based on the phenomenon we call sound.
Sound can be used as a weapon. Imagine that a police officer is chasing a thief. The thief tries to escape. And the officer can’t let him get away. He pulls out a special device, points it at the suspect, and switches it on. The thief drops to the ground. This new weapon is called a Long Range Acoustic Device(LRAD, 远程定向声波发射器). It produces a deafening sound so painful that it temporarily disables a person. The noise from the LRAD is directed like a ray of light and travels only into the ears of that person, but it is not deadly.
For those who hunger for some peace and quiet, sound can now create silence. Let’s say you are at the airport, and the little boy on the seat next to you is humming(哼唱) a short commercial song. He hums it over and over again, and you are about to go crazy. Thanks to the Silence Machine, a British invention, you can get rid of the sound without upsetting the boy or his parents. One may wonder how the Silence Machine works. Well, it functions by analyzing the waves of the incoming sound and creating a second set of outgoing waves. The two sets of waves cancel each other out. Simply turn the machine or point it at the target, and your peace and quiet comes back.
Directed sound is a new technology that allows companies to use sound in much the same way spotlights(聚光灯) are used in the theater. A spotlight lights up only one section of a stage; similarly, “spotsound” creates a circle of sound in on targeted area. This can be useful for businesses such as restaurants and stores because it offers a new way to attract customers. Restaurants can offer a choice of music along with the various food choices on the menu, allowing customers more control over the atmosphere in which they are dining. Directed sound is also beginning to appear in shopping centers and even at homes.
71．What could be inferred from Paragraph 2 about the effect of the LRAD
A．It causes temporary hearing loss.
B．It slows down a running man.
C．It makes it easy to identify a suspect.
D．It keeps the suspect from hurting others.
72．The Silence Machine is a device specially designed to ________.
A．silence the people around you
B．remove the sound of commercials
C．block the incoming sound waves
D．stop unwanted sound from affecting you
73．What feature do spotsounds and spotlights share
A．They travel in circles.
B．They clear the atmosphere.
C．They can be transformed into energy.
D．They can be directed onto a specific area.
74．Directed sound can be used for ________.
A．creative designs of restaurant menus
B．ideal sound effects on the theater stage
C．different choices of music for businesses
D．strict control over any suspicious customer
75．What does the passage focus on
A．How professionals invented sound products.
B．Inventions in the field of sound technology.
C．The growing interest in the study of sound.
D．How sound engineers work in their studios.
（2020·全国·高考真题）According to a recent study in the Journal of Consumer Research, both the size and consumption habits of our eating companions can influence our food intake. And contrary to existing research that says you should avoid eating with heavier people who order large portions(份), it's the beanpoles with big appetites you really need to avoid.
To test the effect of social influence on eating habits, the researchers conducted two experiments. In the first, 95 undergraduate women were individually invited into a lab to ostensibly(表面上)participate in a study about movie viewership. Before the film began, each woman was asked to help herself to a snack. An actor hired by the researchers grabbed her food first. In her natural state, the actor weighed 105 pounds. But in half the cases she wore a specially designed fat suit which increased her weight to 180 pounds.
Both the fat and thin versions of the actor took a large amount of food. The participants followed suit, taking more food than they normally would have. However, they took significantly more when the actor was thin.
For the second test, in one case the thin actor took two pieces of candy from the snack bowls. In the other case, she took 30 pieces. The results were similar to the first test: the participants followed suit but took significantly more candy when the thin actor took 30 pieces.
The tests show that the social environment is extremely influential when we're making decisions. If this fellow participant is going to eat more, so will I. Call it the “I’ll have what she's having” effect. However, we'll adjust the influence. If an overweight person is having a large portion, I'll hold back a bit because I see the results of his eating habits. But if a thin person eats a lot, I'll follow suit. If he can eat much and keep slim, why can't I
76．What is the recent study mainly about
A．Food safety. B．Movie viewership.
C．Consumer demand. D．Eating behavior.
77．What does the underlined word “beanpoles” in paragraph 1 refer to
A．Big eaters. B．Overweight persons.
C．Picky eaters. D．Tall thin persons.
78．Why did the researchers hire the actor
A．To see how she would affect the participants.
B．To test if the participants could recognize her.
C．To find out what she would do in the two tests.
D．To study why she could keep her weight down.
79．On what basis do we “adjust the influence” according to the last paragraph
A．How hungry we are. B．How slim we want to be.
C．How we perceive others. D．How we feel about the food.
（2020·浙江·高考真题）Challenging work that requires lots of analytical thinking, planning and other managerial skills might help your brain stay sharp as you age, a study published Wednesday in the journal Neurology suggests.
Researchers from the University of Leipzig in Germany gathered more than 1, 000 retired workers who were over age 75 and assessed the volunteers’ memory and thinking skills through a battery of tests. Then, for eight years, the scientists asked the same group to come back to the lab every 18 months to take the same sorts of tests.
Those who had held mentally stimulating(刺激), demanding jobs before retirement tended to do the best on the tests. And they tended to lose cognitive(认知) function at a much slower rate than those with the least mentally challenging jobs. The results held true even after the scientists accounted for the participants’ overall health status.
“This works just like physical exercise, ” says Francisca Then, who led the study. “After a long run, you may feel like you’re in pain, you may feel tired. But it makes you fit. After a long day at work-sure, you will feel tired, but it can help your brain stay healthy. ”
It's not just corporate jobs, or even paid work that can help keep your brain fit, Then points out. A waiter’s job, for example, that requires multitasking, teamwork and decision-making could be just as stimulating as any high-level office work. And “running a family household requires high-level planning and coordinating(协调), ” she says. “You have to organize the activities of the children and take care of the bills and groceries. ”
Of course, our brains can decline as we grow older for lots of reasons-including other environmental influences or genetic factors. Still, continuing to challenge yourself mentally and keeping your mind busy can only help.
80．Why did the scientists ask the volunteers to take the tests
A．To assess their health status. B．To evaluate their work habits.
C．To analyze their personality. D．To measure their mental ability.
81．How does Francisca Then explain her findings in paragraph 4
A．By using an expert’s words. B．By making a comparison.
C．By referring to another study. D．By introducing a concept.
82．Which of the following is the best title for the text
A．Retired Workers Can Pick Up New Skills
B．Old People Should Take Challenging Jobs
C．Your Tough Job Might Help Keep You Sharp
D．Cognitive Function May Decline As You Age
（2020·浙江·高考真题）The traffic signals along Factoria Boulevard in Bellevue, Washington, generally don't flash the same length of green twice in a row, especially at rush hour. At 9:30am, the full red/yellow/green signal cycle might be 140 seconds. By 9:33am, a burst of additional traffic might push it to 145 seconds. Less traffic at 9:37am could push it down to 135. Just like the traffic itself, the timing of the signals changes.
That is by design. Bellevue, a fast-growing city just east of Seattle, uses a system that is gaining popularity around the US: intersection(十字路口) signals that can adjust in real time to traffic conditions. These lights, known as adaptive signals, have led to significant declines in both the trouble and cost of travels between work and home.
“Adaptive signals can make sure that the traffic demand that is there is being addressed, ” says Alex Stevanovic, a researcher at Florida Atlantic University.
For all of Bellevue’s success, adaptive signals are not a cure-all for jammed roadways. Kevin Balke, a research engineer at the Texas A&M University Transportation Institute, says that while smart lights can be particularly beneficial for some cities, others are so jammed that only a sharp reduction in the number of cars on the road will make a meaningful difference. “It’s not going to fix everything, but adaptive signals have some benefits for smaller cities,” he says.
In Bellevue, the switch to adaptive signals has been a lesson in the value of welcoming new approaches. In the past, there was often an automatic reaction to increased traffic: just widen the roads, says Mark Poch, the Bellevue Transportation Department’s traffic engineering manager. Now he hopes that other cities will consider making their streets run smarter instead of just making them bigger.
83．What does the underlined word “that” in paragraph 2 refer to
A．Increased length of green lights. B．Shortened traffic signal cycle.
C．Flexible timing of traffic signals. D．Smooth traffic flow on the road.
84．What does Kevin Balke say about adaptive signals
A．They work better on broad roads.
B．They should be used in other cities.
C．They have greatly reduced traffic on the road.
D．They are less helpful in cities seriously jammed.
85．What can we learn from Bellevue’s success
A．It is rewarding to try new things. B．The old methods still work today.
C．It pays to put theory into practice. D．The simplest way is the best way.
（2020·全国·高考真题）We are the products of evolution, and not just evolution that occurred billions of years ago. As scientists look deeper into our genes (基因), they are finding examples of human evolution in just the past few thousand years. People in Ethiopian highlands have adapted to living at high altitudes. Cattle -raising people in East Africa and northern Europe have gained a mutation (突变) that helps them digest milk as adults.
On Thursday in an article published in Cell, a team of researchers reported a new kind of adaptation - not to air or to food, but to the ocean. A group of sea-dwelling people in Southeast Asia have evolved into better divers. The Bajau, as these people are known, number in the hundreds of thousands in Indonesia, Malaysia and the Philippines. They have traditionally lived on houseboats; in recent times, they’ve also built houses on stilts (支柱) in coastal waters. “They are simply a stranger to the land,” said Redney C．Jubilado, a University of Hawaii researcher who studies the Bajau.
Dr. Jubilado first met the Bajau while growing up on Samal Island in the Philippines. They made a living as divers, spearfishing or harvesting shellfish. “We were so amazed that they could stay underwater much longer than us local islanders,” Dr. Jubilado said. “I could see them actually walking under the sea.”
In2015, Melissa Ilardo, then a graduate student in genetics at the University of Copenhagen, heard about the Bajau. She wondered if centuries of diving could have led to the evolution of physical characteristics that made the task easier for them. “it seemed like the perfect chance for natural selection to act on a population,” said Dr. Ilardo. She also said there were likely a number of other genes that help the Bajau dive.
86．What does the author want to tell us by the examples in paragraph 1
A．Environmental adaptation of cattle raisers. B．New knowledge of human evolution.
C．Recent findings of human origin. D．Significance of food selection.
87．Where do the Bajau build their houses
A．In valleys. B．Near rivers. C．On the beach. D．Off the coast.
88．Why was the young Jubilado astonished at the Bajau
A．They could walk on stilts all day. B．They had a
