说明文——2024届高考英语高考阅读理解文体分类练学校:___________姓名:___________班级:___________考号:___________一、阅读理解Medical artificial intelligence (AI) can perform with expert-level accuracy and deliver cost- effective care. IBM's Watson diagnoses (诊断) heart disease better than cardiologists (心脏病专家) do. Chatbots give better medical advice to patients in place of nurses. Some forecast that medical AI will enter 90% of hospitals and replace as much as 80% of what doctors currently do. Yet, as our recent research suggests, patients show a strong resistance to medical AI.The reason, we found, is not the belief that AI provides lower care. Nor is it that patients think that AI is more costly or less informative. Rather, resistance to medical AI seems to come from a belief that AI does not take into account one's specific circumstances. People view themselves as unique. By contrast, they think medical care delivered by AI providers is suited to treat an average patient but unsuitable to account for the unique circumstances that apply to an individual. No wonder that medical AI providers are given a cold welcome.There are a number of steps that care providers can take to overcome patients' resistance to medical AI. For example, if an AI provider is capable of tailoring its recommendation for whether to have a surgery to each patient's unique characteristics and medical history, patients would be likely to follow the treatment recommendations of the AI provider. In addition, health care providers could also deliver individualized health care by explaining how the algorithms (算法) work and sharing patients' reviews with the media. Having a physician confirm the recommendation of an AI provider should make people more willing to accept AI-based care. People are comfortable using medical AI if a physician remains in charge of the ultimate decision.AI-based health care technologies are being developed and employed at an impressivethem will require that we first overcome patients' doubt of having an algorithm, rather than a person making decisions about their care.1.What made people resist the medical AI?A. A sufferer's temper ignored by medical AI.B. People's lasting trust in a human doctor's ability.C. The concern about its personalization in treatment.D. The accuracy of the information from medical AI.2.What can be a solution to patients' resistance according to the author?A. Treating sufferers as average patients.B. Providing a more specific treatment.C. Getting the algorithms prioritized in time.D. Keeping away from the influence of a physician.3.Which word can replace the underlined word "harnessing" in the last paragraph?A. Weakening.B. Storing.C. Destroying.D. Using.4.What is the suitable title for the text?A. Advantages of Medical AIB. Potential Application of AIC. How AI Replaces Nurses in HealthcareD. The Challenge That Medical AI FacesWith nearly a quarter of global greenhouse gas coming from all types of transportation, can we keep ourselves off gas-powered vehicles to avoid the worst effects? As more governments push for urgent action on climate change, quite a few companies are betting their future—that millions of consumers are finally ready for electric-powered vehicles. Modern battery-powered cars are selling fast and zero-emission(排放) planes are coming. These changes, both leading to a more sustainable future, are reinventing how we get from here to there.Cars and trucks have undergone their greatest improvement since the automobile's existence more than a century ago. Almost overnight, the era of the electric car has arrived. Electricity has the advantage that it works without smell and with less noise. Global annual sales of electric vehicles are expected to soar from just over 3 million today to 14 million by2025. Just a month after Ford unveiled an electric version of the popular F-150, customers had reserved more than 100,000 of them. The price is about $10,000 above the gas-powered one, but Ford says the electric model will cost much less to maintain. Everything creating a green revolution on the ground is of limited help in the sky for the time being.High-storage batteries are useless at present when it comes to the technological challenge of launching a few hundred people into the sky and carrying them thousands of miles. No battery yet invented can power, say, a Boeing 747 from New York to London. Promising improvements, however, do add up. Developments with zero-emission, battery-powered electric engines are already happening in commercial flights, involving trips of limited duration and distance. Airlines specializing in short journeys with small planes will lead theway to electric flights.Our planet's health depends on zeroing out carbon dioxide emissions by 2050, and yet, by the timetable needed to address the climate challenge, the shift away from gas-powered vehicles remains far too slow. Nevertheless, the train has left the station. Someday, electric-powered transportation will be as common5.Why are many companies switching to electric-powered vehicles?A.To reinvent the way we travel.B.To cut the costs of car production.C.To improve the quality of products.D.To pursue sustainable development.6.What do we know about the electric car?A.It came into use a century ago.B.It enjoys increasing popularity.C.It sells better than the traditional one.D.It costs less than the gas-powered one. 7.What does the author intend to do in Paragraph 3?A.To show the disadvantages of battery power.B.To emphasize the significance of short flights.C.To state the developments of commercial flights.D.To stress the future prospects of electric planes.8.What does the author mean by saying "the train has left the station"?A.Train transportation has improved.B.Green transportation is on its way.C.The electric train is running regularly.D.The gas-powered train has become the past.Technology has revolutionized (使革命化) the way we work in many ways. One of the most significant changes has been the shift towards remote and flexible work. With the rise of internet and cloud-based software, workers are no longer tied to a physical office and can work from anywhere with an internet connection. This has allowed for greater flexibility and work-life balance, as well as reduced commuting (通勤) time and costs.Another major change is the increasing use of automation and artificial intelligence in the workplace. This has the potential to increase efficiency and productivity, as well as reduce the need for certain types of work. However, it also raises concerns about job displacement and the need for workers to adapt to new technologies.Finally, technology has greatly expanded the types of jobs available. With the rise of the gig (临时工) economy and freelance (自由职业者) work, workers can now find opportunities in areas such as graphic design (平面设计), copywriting (文案撰写), and socialmedia management. This has created opportunities for individuals to work in areas that were previously inaccessible or did not exist.9.What is the shift in the way we work brought about by technology?A. Flexible and remote work.B. Tying people to a physical office.C. Increased commuting and travel.D. Higher costs and lower productivity. 10.What is the impact of internet and cloud-based software on the way we work?A. It has reduced work-life balance.B. It has increased commuting time and costs.C. It has allowed for greater flexibility and work-life balance.D. It has caused job displacement.11.What are the potential benefits of automation and AI in the workplace?A. Increased job displacement.B. Reduced efficiency and productivity.C. Increased efficiency and productivity.D. Increased commuting and travel.12.What has technology allowed for in terms of job availability?A. Technology has decreased the number of available jobs.B. Technology has created opportunities for individuals to work in areas that were previously inaccessible or did not exist.C. Technology has only impacted traditional office jobs.D. Technology has increased commuting time and costs.Penguins are survivors. Modern species of the adorable birds resist freezing temperatures or dive deep in swift currents. In fact, penguins have been doing their adorable thing for millions of years. Prehistoric penguin species date back to the days of the dinosaurs. A team of researchers in New Zealand have discovered one more member of the ancient family, a tiny and distinctly precious species newly known as Eudyptula wilsonae. Its name, which comes from a New Zealand respected seabird researcher Kerry-Jayne Wilson MNZM, means Wilson's little penguin. Explaining in their recent paper, the researchers detail how the examination of small fossilized skulls(颅骨) led to the classification of this cute creature who lived 50 million years ago.Two fossils were discovered on New Zealand's North Island. Only the skulls are still in existence, and they are slightly narrower than those of modern little penguins which currently frolic(嬉戏) along the island's coasts. From the one young and one adult skull, the researchers determined it was a new species. They likely stood just about a foot tall and weighed2 pounds, much like the modern penguins. In fact, the new species may bea late Pliocene ancestor of the modern birds."This is important when thinking about the origins of these penguins, the evolution of the seabird diversity of New Zealand and the dynamic environment in which they live," co-author Daniel Thomas said in a statement. "For one thing, the climate has changed a lot over this time, and this lineage has been robust(强健的) to those changes." In fact, recent warming has resulted in new challenges for modern little penguins-many starved to death in 2022 as fish moved to cooler waters beyond the diving abilities of the penguins.Ancient penguins' ability to survive when temperatures were warmer in their own time might have modern applications. As cute as these fossilized small penguins are, the modern variety needs humans to look beyond their sweet nature to recognize the complexity of their survival.13.What is Eudyptula wilsonae's name related to?A. A site.B. A shape.C. A person.D. Penguin's appearance.14.What is the feature of the new species?A. They look like modern birds.B.They enjoyed playing by the coasts.C. They share similar heights to modern penguins.D. They are heavier than modern penguins.15.What can be inferred from the third paragraph?A. Thomas attached insufficient importance to the finding.B. The living environment of penguins is worsening.C. The changing climate has little effect on penguins.D. Many fish died due to changes in water temperature.16.Where is the text most likely from?A. An essay from a scientific magazine.B. An introduction to a book.C.A guidebook to biology research.D. A review of penguins' evolution.“Pale Moon rains. Red Moon blows. White Moon neither rains nor snows.” For generations, people have watched the Moon for signs of changes in the weather. The Moon does, in fact, affect the Earth’s climate and weather patterns in different ways.The most obvious effect the Moon has on the Earth can be seen in the ocean tides. A world without tides would have very different weather systems. Tides are one factor that influences the movement of ocean currents, which move warm or cool water around the Earth. Thus, the water temperature changes. Warm ocean currents bring warmer and wetter weather,while cold ocean currents bring colder and drier weather.the amount of Arctic ice. Tidal forces (潮汐力) act to break up ice sheets and change ocean heat flows, changing the amount of ice in the Arctic Ocean. Satellite measurements have shown that the poles are 0.55℃ warmer during a full Moon.The Moon’s influence, sometimes slight and sometimes strong, has had an important impact on life on Earth. Some scientists argue that it is the Moon that made life possible in the first place. The Moon makes the Earth move steadily as it is spinning (自转), helping to give us a steady climate. Without it, the Earth would lose balance. The Moon is our closest friend, without which the Earth would be a very lonely place.17.Why do people watch the Moon according to Paragraph 1?A. To appreciate the moon.B. To record weather patterns.C. To prepare for extreme weather.D. To observe signs of weather changes 18.What impact does the Moon have on the Earth?A. It influences water temperatureB. It makes weather hard to predictC. It turns the earth colder and drier.D. It changes the size of ocean currents. 19.What does the underlined word “fluctuations” mean?A. Change.B. Increase.C. Flow.D. Measurement. 20.What is the best title for the passage?A. Changes of Ocean Heat Flows.B. Patterns of the Earth’s Climate.C. Causes of Changes in Polar Weather.D. Effects of the Moon on Global Weather Osa is an athletic yet stubborn 62-pound German shepherd. The six-year-old dog has mastered the art of sniffing(嗅,闻) out cancer and is key to a research project that has the potential to change oncology(肿瘤学).Osa is part of an ambitious effort launched five years ago at the University of Pennsylvania that aims to develop one of the most powerful scent-detection(气味探测) machines in the world: the canine nose. She is able to distinguish between blood samples (样本) taken from cancer patients and healthy people simply by sniffing them.In fact, Osa is one of five cancer-detection dogs trained by Annemarie DeAngelo and her workmates at the university’s Penn Vet Working Dog Centre. The most important goal is to develop an “electronic sniffer” that can have similar cancer-sniffing superpowers of Osa and her pals. Osa arrived at the Penn Vet Working Dog Centre from a breeder at two months ofage. Ever since, she has taken training. The process is demanding, challenging and repeated until the dog has mastered the most basic task of all. Finally, she has succeeded in sniffing out cancer. To change Osa’s outstanding abilities into an electronic nose, researchers use a similar way to train the machine.An electronic nose prototype(原型,模型) has been built, and it’s successful in sniffing out cancer 90 to 95 percent of the time. That team has also correctly detected different types of cancer, and is building a cancer-detecting device for the National Institutes of Health. One aim is to be able to distinguish between early-stage and late-stage cancer. “It would be amazing to ide ntify people at an early stage and really have an effect on saving lives,” says a researcher. “The dogs have been able to detect that. With that ability, a blood test could be sent to a central lab, or ideally performed in a doctor’s office, making some hi dden cancers a thing of the past. We expect that the cancer-sniffer device will be completed soon. 21.What can we learn about Osa from the first two paragraphs?A. She uses nose to detect the presence of cancer.B. She can change the course of the oncology.C. She was too stubborn to join the research.D. She used to be an athletic German shepherd.22.Which of the following best describes the training according to Paragraph 3?A. Purposeful.B. Boring.C. Strict.D. Endless.23.What can we infer from t he researcher’s words?A. Distinguishing cancers is important in early experiments.B. Blood tests will be more difficult in the future.C. There will be more dogs tested for detecting cancer.D. The hidden cancers may be detected by an electronic nose soon.24.What is the text mainly about?A. The result of a study on dogs’ life.B. The role of dogs in detecting cancers.C. The importance of having a blood test.D. The ways to distinguish cancers.参考答案1.答案:C解析:细节理解题。

Introduction。

Cats and dogs are two of the most popular pets in the world. While both animals make great companions, they have distinct differences in terms of behavior, care, and characteristics. In this article, we will compare and contrast cats and dogs in various aspects to help potential pet owners make an informed decision.Behavior。

Cats are known for their independent and aloof nature. They are often seen as more reserved and less social than dogs. Cats are also known for their agility and hunting instincts. On the other hand, dogs are known for their loyalty and affectionate nature. They are often referred to as "man's best friend" due to their strong bond with their owners. Dogs are also known for their protective instincts and are often used as guard animals.Care。

高考英语说明文5篇1Here is an astonishing and significant fact: Mental work alone can’t make us tire. It sounds absurd. But a years ago, scientists tried to find out how long the human brain could labor without reaching a stage of fatigue (疲劳). To the amazement of these scientists, they discovered that blood passing through the brain, when it is active, shows no fatigue at all! If we took a drop of blood from a day laborer, we would find it full of fatigue toxins(毒素) and fatigue products. But if we took blood from the brain of an Albert Einstein, it would show no fatigue toxins at the end of the day.So far as the brain is concerned, it can work as well and swiftly at the end of eight or even twelve hours of effort as at the beginning. The brain is totally tireless. So what makes us tired?Some scientists declare that most of our fatigue comes from our mental and emotional(情绪的) attitudes. One of England’s most outstanding scientists, J.A. Hadfield, says, “The greater part of the fatigue from which we suffer is of mental origin. In fact, fatigue of purely physical origin is rare.”Dr. Brill, a famous American scientist, goes even further. He declares, “One hundred percent of the fatigue of sitting worker in good health is due to emotional problems.”What kinds of emotions make sitting workers tired? Joy? Satisfaction? No! A feeling of being bored, anger, anxiety, tenseness, worry, a feeling of not being appreciated---those are the emotions that tire sitting workers. Hard work by itself seldom causes fatigue. We get tired because our emotions produce nervousness in the body.1. What surprised the scientists a few years ago?A. Fatigue toxins could hardly be found in a laborer’s blood.B. Albert Einstein didn’t feel worn after a day’s work.C. The brain could work for many hours without fatigue.D. A mental worker’s blood was filled with fatigue toxins.2. According to the author, which of the following can make sitting workers tired?A. Challenging mental work.B. Unpleasant emotions.C. Endless tasks.D. Physical labor3. What’s the author’s attitude towards the scientists’ idea?A. He agrees with them.B. He doubts them.C. He argues against them.D. He hesitates to accept them.4. We can infer from the passage that in order to stay energetic, sitting workers need to ________.A. have some good food.B. enjoy their workC. exercise regularlyD. discover fatigue toxins2They baby is just one day old and has not yet left hospital. She is quiet but alert (警觉). Twenty centimeters from her face researchers have placed a white card with two black spots on it. She stares at it carefully. A researcher removes the card and replaces it by another, this time with the spots differently spaced. As the cards change from one to the other, her gaze(凝视) starts to lose its focus — until a third, with three black spots, is presented. Her gaze returns: she looks at it for twice as long as she did at the previous card. Can she tell that the number two is different from three, just 24 hours after coming into the world?Or do newborns simply prefer more to fewer? The same experiment, but with three spots shown before two, shows the same return of interest when the number of spots changes. Perhaps it is just the newness? When slightly older babies were shown cards with pictures of objects (a comb, a key, an orange and so on), changing the number of objects had an effect separate from changing the objects themselves. Could it be the pattern that two things make, as opposed to three? No again. Babies paid more attention to squares moving randomly on a screen when their number changed from two to three, or three to two. The effect even crosses between senses. Babies who were repeatedly shown two spots became more excited when they then heard three drumbeats than when they heard just two; likewise (同样地)when the researchers started with drumbeats and moved to spots.5. The experiment described in Paragraph 1 is related to the baby’s__.A. sense of hearingB. sense of sightC. sense of touchD. sense of smell6. Babies are sensitive to the change in______.A. the size of cardsB. the colour of picturesC. the shape of patternsD. the number of objects7. Why did the researchers test the babies with drumbeats?A. To reduce the difficulty of the experiment.B. To see how babies recognize sounds.C. To carry their experiment further.D. To keep the babies’interest.8. Where does this text probably come from?A. Science fiction.B. Children’s literature.C. An advertisement.D.A science report3Last night’s meteor(流星) shower left many people in the community dissatisfied and demanding answers. According to Gabe Rothsclild, Emerald Valley’s mayor, people gathered in the suburbs of the city, carrying heavy telescopes, expecting to watch the brightly burning meteors passing through the sky. What they found instead was a sky so brightened by the city’s lights that it darkened the light of the meteors passing overhead.“My family was so frustrated,” admitted town resident Duane Cosby, “We wanted to make this an unforgettable family outing, but it turned out to be a huge disappointments.”Astronomers---scientists who study stars and planets----have been complaining about this problem for decades. They say that light pollution prevents them from seeing objects in the sky that they could see quite easily in the past. They call on people and the government to take measures to fight against it.There is yet a population besides professional and amateur star observers that suffers even more from light pollution. This population consists of birds, bats frogs, snakes, etc. For example, outdoor lighting severely affects migrating(迁徙的)birds. According to the International Dark-Sky Association. “100 million birds a year throughout North America die in crashes with lighted buildings and towers.”Countless more animals casualties(伤亡)result from the use of artificial lighting. Clearly, people enjoy the benefits of lighting their evenings, but some scientists think it can be harmful for humans, too. They worry that exposure to light while sleeping can increase person’s chances of getting cancer.Emerald Valley is only one community that is becoming aware of the negative effects of light pollution. For years, Flagstaff, Arizona, has enforced lighting regulations in its city in order to assist astronomers at the LowellObservatory. Similar efforts have been made worldwide, and a movement is underway to remind us to turn off lights when we are not using them, so that other creatures can share the night.9.It happened last night thatA. the city’s lights affected the meteor watchingB. the meteors flew past before being noticedC. the city light show attracted many peopleD. the meteor watching ended up a social outing10. What do the astronomers complain about?A. Meteor showers occur less often than beforeB. Their observation equipment is in poor repairC. Light pollution has remained unsolved for yearsD. Their eyesight is failing due to artificial lighting11. What the author concerned about according to Paragraph 4?A. Birds may take other migration pathsB. Animals living habits may change suddenlyC. Varieties of animals will become sharply reducedD. Animals’ survival is threatened by outdoor lighting12. Lighting regulations in Flagstaff, Arizona are put into effect toA. Lessen the chance of getting cancerB. create an ideal observation conditionC. ensure citizens a good sleep at nightD. enable all creatures to live in harmony13.What message does the author most want to give us?A. Saving wildlife is saving ourselvesB. Great efforts should be made to save energyC. Human activities should be environmentally friendlyD. New equipment should be introduced for space study4Almost every machine with moving parts has wheels, yet no one knows exactly when the first wheel was invented or what it was used for. We do know,however,that they existed over 5,500years ago in ancient Asia.The oldest known transport wheel was discovered in 2002 in Slovenia. It is over 5,100 years old. Evidence suggests thatwheels for transport didn't become popular for .while, though . This could be because animals did a perfectly good job of carrying farming tools and humans around.But it could also be because of a difficult situation. While wheels need to roll on smooth surfaces, roads with smooth surfaces weren't going to be constructed until there was plenty of demand for them. Eventually, road surfaces did become smoother, but this difficult situation appeared again a few centuries later. There had been no important changes in wheel and vehicle design before the arrival of modern road design.In the mid-1700s,a Frenchman came up with a new design of road--a base layer (层)of large stones covered with a thin layer of smaller atones. A Scotsman improved on this design in the 1820s and a strong, lasting road surface became a reality. At around the same time, metal hubs(the central part of a wheel) came into being, followed by the Wheels were invented in 1967, sixty years after the appearance of tarmacked roads(泊油路). As wheel design took off, vehicles got faster and faster.14. What might explain why transport wheels didn’t become popular for some time?A. Few knew how to use transport wheels.B. Humans carried farming tools just as well.C. Animals were a good means of transport.D. The existence of transport wheels was not known.15.What do we know about road design from the passage?A. It was easier than wheel design.B. It improved after big changes in vehicle design.C. It was promoted by fast-moving vehicles.D. It provided conditions for wheel design to develop.16. How is the last paragraph mainly developed?A. By giving examples.B. By making comparisons.C. By following time order.D. By making classifications.17. What is the passage mainly about?A. The beginning of road deaign.B. The development of transport wheels.C. The history of public transport.D. The invention of fast-moving vehicles.5Imagination and fantasy can play an important role in achieving the things we fear. Children know this very well. Fred Epstein, in his book I Make It to Five, tells a story he heard from one of his friends about Tom, a four-year-old boy with a cancer in his back bone. He came through several operations and a lot of pain by mastering his imagination.Tom loved to pretend, and he particularly loved to play superheroes. Dr. Epstein explained that it was actually a brilliant way for his young mind to handle the terrifying and painful life he led.The day before his third trip to the operating room, Tom was terribly afraid. “ Maybe I could go as Superman,” he whispered to his mom. Hearing this, the mother hesitated for while. She has avoided buying the expensive costume(戏装), but finally she agreed.The next day Tom appeared as the powerful Superman, showing off through the hospital halls and coolly waving his hand to the people greeting him along the way. And Tom, with the strength of his fantasy, successfully made it through the operation.The power of imagination need not be reserved for children only. We all have the power to use our fantasies to attempt things we never thought possible, to go through those things that seem impossible, and to achieve what we never believed we could. Just as Dr. Epstein puts it, “If you can dream it, you can do it.”It doesn’t mean that you should dress as a superhero for your next job interview. But, next time you are tested in a way that seems impossible, imagine what it would take to overcome it. Become the person you need to become to win over your challenge and do it in your mind first. So, let your imagination run wild, and dare to dream.18. What do we know about Tom?A. He was seriously ill.B. He was a dishonest boy.C. He was crazy about magic.D. He was Dr. Epstein’s patient.19. What can be inferred about Tom’s mother?A. She was a rich lady.B. She refused Tom’s request.C. She wanted Tom to be a superhero.D. She wanted to get Tom through the pain.20. When Tom went for the third operation, he_________.A. pretended to be painfulB. acted like a superheroC. appeared in poor spiritsD. argued with his mother21. In the last paragraph, you are advised________.A. to go through some difficult testsB. to wake up from your wilddreamsC. to become a powerful person in your mindD. to wear expensive clothes for job interviews22. What is the purpose of the passage?A. To tell us an interesting story.B. To help us make right decisions.C. To advise us to care about children.D. To encourage us to use our imagination.。

This population consists of birds, bats frogs, snakes, etc. For example, outdoor lighting severely affects migrating(迁徙的)birds. According to the International Dark-Sky Association. “100million birds a year throughoutNorth America die in crashes 撞碎with lighted buildings and towers.”Countless more animals casualties(伤亡)result from the use of artificial lighting. Clearly, people enjoy the benefits of lighting their evenings, butsome scientists think it can be harmful for humans, too.

We do know,however,that they existed over 5,500years ago in ancient Asia.The oldest known transport wheel was discovered in 2002 in Slovenia. It is over 5,100 years old. Evidence suggests thatwheels for transport didn't become popular for .while, though . Thiscould be because animals did a perfectly good job of carryingfarming tools and humans around.But it could also be because of a difficult situation. While wheels need to roll on smooth surfaces, roads with smooth surfacesweren't going to be constructed until there was plenty of demandfor them. Eventually, road surfaces did become smoother, but this difficult situation appeared again a few centuries later. There hadbeen no important changes in wheel and vehicle design before thearrival of modern road design.In the mid-1700s,a Frenchman came up with a new design ofroad--a base layer (层)of large stones covered with a thin layer ofsmaller stones. A Scotsman苏格兰人improved on this design in the 1820s and a strong, lasting road surface became a reality.

备战高考英语名校模拟真题速递(江苏专用)第六期专题06 阅读理解之说明文10篇(2024·江苏南通·模拟预测)Mark Temple, a medical molecular (分子的) biologist, used to spend a lot of time in his lab researching new drugs for cancer treatments. He would extract DNA from cells and then add a drug to see where it was binding (结合) along the chemical sequence(序列). Before he introduced the drug, he’d look at DNA combination on a screen to see what might work best for the experiment, but the visual readout of the sequences was often unimaginably large.So Temple wondered if there was an easier way to detect favorable patterns. I realized I wanted to hear the sequence,” says Temple, who is also a musician. He started his own system of assigning notes to the different elements of DNA — human DNA is made of four distinct bases, so it was easy to start off with four notes — and made a little tune out of his materials. This trick indeed helped him better spot patterns in the sequences, which allowed him to make better choices about which DNA combinations to use.Temple isn’t the first person to turn scientific data into sound. In the past 40 years, researchers have gone from exploring this trick as a fun way to spot patterns in their studies tousing it as a guide to discovery. And the scientific community has come to realize that there’s some long-term value in this type of work. Temple, who from that first experiment has created his own algorithmic software to turn data into sound, believes the resulting music can be used to improve research and science communication.So Temple decided to add layers of sound to make the sonification (可听化) into songs. He sees a clear difference between “sonification” and “musification”. Using sound to represent data is scientific, but very different from using creative input to make songs. The musical notes from DNA may be melodic to the human ear, but they don’t sound like a song you’d listen to on the radio. So when he tried to sonify the virus, he added layers of drums and guitar, and had some musician friends add their own music to turn the virus into a full-blown post-rock song.Temple sees this work as an effective communication tool that will help a general audience understand complex systems in biology. He has performed his songs in public at concert halls in Australia.1.What is Mark Temple’s purpose in turning DNA data into sound?A.To help him fight boredom.B.To develop his creative ability.C.To make his drug more powerful.D.To aid the process of his experiments.2.What can we learn about Temple’s system?A.Its effect remains to be seen.B.It failed to work as expected.C.It is too complicated to operate.D.It has produced satisfying results.3.Why did Temple try to make the virus sound like real music when sonifying it?A.To get rid of public fear of the virus.B.To show h1s talent in producing music.C.To facilitate people’s understanding of science.D.To remind people or the roe or Science in art creation.4.What does the text mainly talk about?A.Why scientists are turning molecules into music.B.How scientists help the public understand science.C.Why music can be the best way to present science.D.How music helps scientists conduct their research.(2024·江苏南通·模拟预测)Phonics, which involves sounding out words syllable (音节) by syllable, is the best way to teach children to read. But in many classrooms, this can be a dirty word. So much so that some teachers have had to take phonics teaching materials secretly into the classroom. Most American children are taught to read in a way that study after study has found to be wrong.The consequences of this are striking. Less than half of all American adults were efficient readers in 2017. American fourth graders rank 15th on the Progress in International Literacy Study, an international exam.America is stuck in a debate about teaching children to read that has been going on for decades. Some advocate teaching symbol sound relationships (the sound k can be spelled as c, k, ck, or ch) known as phonics Others support an immersive approach (using pictures of cat to learn the word cat), known as “whole language”. Most teachers today, almost three out of four according to a survey by EdWeek Research Centre in 2019, use a mix of the two methods called “balanced literacy”.“A little phonics is far from enough.” says Tenette Smith, executive director of elementary education and reding at Mississippi’s education department. “It has to be systematic and explicitly taught.”Mississippi, often behind in social policy, has set an example here. In a state once blamed for its low reading scores, the Mississippi state legislature passed new literacy standards in 2013.Since then Mississippi has seen remarkable gains., Its fourth graders have moved from 49th (out of 50 states) to 20th on the National assessment of Educational Progress, a nationwide exam.Mississippi’s success is attributed to application of reading methods supported by a body of research known as the science of reading. In 1997 experts from the Department of Education ended the “reading war” and summed up the evidence. They found that phonics, along with explicit instruction in phonemic (音位的) awareness,fluency and comprehension, worked best.Yet over two decades on, “balanced literacy” is still being taught in classrooms. But advances in statistics and brain imaging have disproved the whole-language method. To the teacher who is an efficient reader, literacy seem like a natural process that requires educated guessing, rather than the deliberate process emphasized by phonics. Teachers can imagine that they learned to read through osmosis(潜移默化) when they were children. Without proper training, they bring this to classrooms.5.What do we learn about phonics in many American classrooms?A.It is ill reputed.B.It is mostly misapplied.C.It is totally ignored.D.It is seemingly contradictory.6.What has America been witnessing?A.A burning passion for improving teaching methods.B.A lasting debate over how to teach children to read.C.An increasing concern with children’s inadequacy in literacy.D.A forceful advocacy of a combined method for teaching reading.7.What’s Tenette Smith’s attitude towards “balanced literacy”?A.Tolerant.B.Enthusiastic.C.Unclear.D.Disapproving.8.According to the author what contributed to Mississippi’s success?A.Focusing on the natural process rather than deliberate training.B.Obtaining support from other states to upgrade teaching methods.C.Adopting scientifically grounded approaches to teaching reading.D.Placing sufficient emphasis upon both fluency and comprehension.(2024·江苏泰州·一模)A satellite is an object in space that orbits around another. It has two kinds — natural satellites and artificial satellites. The moon is a natural satellite that moves around the earth while artificial satellites are those made by man.Despite their widespread impact on daily life, artificial satellites mainly depend on different complicated makeups. On the outside, they may look like a wheel, equipped with solar panels or sails. Inside, the satellites contain mission-specific scientific instruments, which include whatever tools the satellites need to perform their work. Among them, high-resolution cameras and communication electronics are typical ones. Besides, the part that carries the load and holds all the parts together is called the bus.Artificial satellites operate in a systematic way just like humans. Computers function as the satellite’s brain, which receive information, interpret it, and send messages back to the earth. Advanced digital cameras serve asthe satellite’s eyes. Sensors are other important parts that not only recognize light, heat, and gases, but also record changes in what is being observed. Radios on the satellite send information back to the earth. Solar panels provide electrical power for the computers and other equipment, as well as the power to move the satellite forward.Artificial satellites use gravity to stay in their orbits. Earth’s gravity pulls everything toward the center of the planet. To stay in the earth’s orbit, the speed of a satellite must adjust to the tiniest changes in the pull of gravity. The satellite’s speed works against earth’s gravity just enough so that it doesn’t go speeding into space or falling back to the earth.Rockets carry satellites to different types and heights of orbits, based on the tasks they need to perform. Satellites closer to the earth are in low-earth orbit, which can be 200-500 miles high. The closer to the earth, the stronger the gravity is. Therefore, these satellites must travel at about 17,000 miles per hour to keep from falling back to the earth, while higher-orbiting satellites can travel more slowly.9.What is Paragraph 2 of the text mainly about?A.The appearance of artificial satellites.B.The components of artificial satellites.C.The basic function of artificial satellites.D.The specific mission of artificial satellites.10.What is the role of computers in artificial satellites?A.Providing electrical power.B.Recording changes observed.C.Monitoring space environment.D.Processing information received.11.How do artificial satellites stay in their orbits?A.By relying on powerful rockets to get out of gravity.B.By orbiting at a fixed speed regardless of gravity’s pull.C.By changing speed constantly based on the pull of gravity.D.By resisting the pull of gravity with advanced technologies.12.Why do satellites in higher-earth orbit travel more slowly?A.They are more affected by earth’s gravity.B.They take advantage of rockets more effectively.C.They have weaker pull of gravity in higher orbits.D.They are equipped with more advanced instruments.(2024·江苏泰州·一模)The human body possesses an efficient defense system to battle with flu viruses. The immune system protects against the attack of harmful microbes (微生物) by producing chemicals called antibodies, which are programmed to destroy a specific type of microbe. They travel in the blood and search the body for invaders (入侵者). When they find an invasive microbe, antibodies attack and destroy any cell thatcontains the virus. However, flu viruses can be a terrible enemy. Even if your body successfully fights against the viruses, with their ability to evolve rapidly, your body may have no protection or immunity from the new ones.Your body produces white blood cells to protect you against infectious diseases. Your body can detect invading microbes in your bloodstream because they carry antigens in their proteins. White blood cells in your immune system, such as T cells, can sense antigens in the viruses in your cells. Once your body finds an antigen, it takes immediate action in many different ways. For example, T cells produce more antibodies, call in cells that eat microbes, and destroy cells that are infected with a virus.One of the best things about the immune system is that it will always remember a microbe it has fought before and know just how to fight it again in the future. Your body can learn to fight so well that your immune system can completely destroy a virus before you feel sick at all.However, even the most cautious people can become infected. Fortunately, medical scientists have developed vaccines (疫苗), which are weakened or dead flu viruses that enter a person’s body before the person gets sick. These viruses cause the body to produce antibodies to attack and destroy the strong viruses that may invade during flu season.13.Why does flu pose a threat to the immune system?A.Microbes contain large quantities of viruses.B.Antibodies are too weak to attack flu viruses.C.The body has few effective ways to tackle flu.D.It’s hard to keep pace with the evolution of viruses.14.What does the underlined word “antigens” refer to in Paragraph 2?A.The cell protecting your body from viruses.B.The matter serving as the indicator of viruses.C.The antibodies helping to fight against viruses.D.The substance destroying cells infected with viruses.15.How do vaccines defend the body against the flu viruses?A.They strengthen the body’s immune system.B.They battle against weakened or dead viruses.C.They help produce antibodies to wipe out viruses.D.They expose the body to viruses during flu season.16.Which of the following is a suitable title for the text?A.Antibodies Save Our Health.B.Vaccines Are Of Great Necessity.C.Infectious Flu Viruses Are Around.D.Human Body Fights Against Flu Viruses.(23-24高三下·江苏扬州·开学考试)A recent study, led by Professor Andrew Barron, Dr. HaDi MaBouDi, and Professor James Marshall, illustrates how evolution has fine-tuned honey bees to make quick judgments while minimizing danger.“Animal lives are full of decisions,” says Professor Barron. “A honey bee has a brain smaller than a sesame (芝麻) seed. And yet it can make decisions faster and more accurately than’ we can. A robot programmed to do a bee’s job would need the backup of a supercomputer.”Bees need to work quickly and efficiently. They need to make decisions. Which flower will have a sweet liquid? While they’re flying, they face threats from the air. While landing, they’re vulnerable to potential hunter, some of which pretend to look like flowers.Researchers trained 20 bees to associate each of the five different colored “flower disks” with their visit history of reward and punishment. Blue flowers always had sugar juice. Green flowers always had a type of liquid with a bitter taste for bees. Other colors sometimes had glucose (葡萄糖). “Then we introduced each bee to a ‘garden’ with artificial ‘flowers’. We filmed each bee and timed their decision-making process,” says Dr. MaBouDi. “If the bees were confident that a flower would have food, they quickly decided to land on it, taking an average of 0.6 seconds. If they were confident that a flower wouldn’t have food, they made a decision just as quickly. If unsure, they took on average 1.4 seconds, and the time reflected the probability that a flower had food.”The team then built a computer model mirroring the bees’ decision-making process. They found the structure of the model looked very similar to the physical layout of a bee brain. “AI researchers can learn much from bees and other ‘simple’ animals. Millions of years of evolution has led to incredibly efficient brains with very low power requirements,” says Professor Marshall who co-founded a company that uses insect brain patterns to enable machines to move autonomously, like nature.17.Why does Professor Andrew Barron mention “a supercomputer”?A.To illustrate how a honey bee’s brain resemble each other.B.To explain how animals arrive at informed decisions fast.C.To demonstrate how a robot could finish a honey bee’s job.D.To emphasize how honey bees make decisions remarkably.18.Which of the following can best replace “vulnerable to” underlined in paragraph 3?A.Easily harmed by.B.Highly sensitive to.C.Deeply critical to.D.Closely followed by.19.What influenced the speed of trained bees in making decisions?A.Their judgments about reward and punishment.B.Their preference for the colors of flower disks.C.Their confirmation of food’s presence and absence.D.Their ability to tell real flowers from artificial ones.20.What message does Professor James Marshall want to give us?A.The power of bee brains is underestimated.B.Biology can inspire future AI.C.Autonomous machines are changing nature.D.AI should be far more efficient.(23-24高三下·江苏扬州·开学考试)Are you frequently overwhelmed by the feeling that life is leaving you behind, particularly when you look through social media sites and see all the exciting things your friends are up to? If so, you are not alone.FOMO, or Fear of Missing Out, refers to the perception that other people’s lives are superior to our own, whether this concerns socializing, accomplishing professional goals or generally having a more deeply fulfilling life. It shows itself as a deep sense of envy, and constant exposure to it can have a weakening effect on our self-respect. The feeling that we are always being left out of fundamentally important events, or that our lives are not living up to the image pictured by others, can have long-term damaging psychological consequences.While feelings of envy and inadequacy seem to be naturally human, social media seems to have added fuel to the fire in several ways. The reason why social media has such a triggering effect is tied to the appeal of social media in the first place: these are platforms which allow us to share only the most glowing presentations of our accomplishments, while leaving out the boring aspects of life. While this kind of misrepresentation could be characterized as dishonest, it is what the polished atmosphere of social media seems to demand.So how do we avoid falling into the trap of our own insecurities? Firstly, consider your own social media posts. Have you ever chosen photos or quotes which lead others to the rosiest conclusions about your life? Well, so have others and what they’ve left hidden is the fact that loneliness and boredom are unavoidably a part of everyone’s day-to-day life, and you are not the only one feeling left out. Secondly, learn to appreciate the positives. You may not be a regular at exciting parties or a climber of dizzying peaks, but you have your health, a place to live, and real friends who appreciate your presence in their lives. Last of all, learn to shake things off. We are all bombarded daily with images of other people’s perfection, but really, what does it matter? They are probably no more real than the most ridiculous reality TV shows.21.What can frequently experiencing FOMO lead to?A.Harm to one’s feeling of self-value.B.A more satisfying and fulfilling social life.C.Damage to one’s work productivity.D.Less likelihood of professional success.22.What does the author suggest in the third paragraph?A.The primary reason for FOMO is deeply rooted in social media.B.Our own social media posts help us feel much more confident.C.People who don’t share posts on social media are more bored.D.Social media’s nature enhances envious feelings and self-doubt.23.Why does the author mention reality TV shows in the last paragraph?A.To emphasize how false what we see on social media can be.B.To indicate how complicated social media has turned to.C.To figure out how popular and useful social media has been.D.To point out how educational value reality TV shows reflect.24.Which is the best title for the text?A.Myths and misconceptions about FOMO B.FOMO: what it is and how to overcome itC.How FOMO is changing human relationships D.We’re now all in the power of “FOMO addiction”(23-24高三上·江苏泰州·阶段练习)While Huawei’s official website does not call Mate 60 Pro a 5G smartphone, the phone’s wideband capabilities are on par with other 5G smartphones, raising a related question: As a leader in 5G technology, has Huawei managed to develop a 5G smartphone on its own?The answer is not simple. Huawei, as a pioneer in global 5G communication equipment, has played a leading role in the commercialization of 5G technology, with its strong system design and fields such as baseband chips (基带芯片), baseband processors and 5G modems.However, basebands and modems are not the only aspects that define 5G wireless communication. The stability and high-quality signals of a 5G smartphone also depend on other critical components such as RF transceivers (射频收发器) and RF front ends and antennas (天线) . These components are largely dominated by four US high-tech giants—Qualcomm, Avago Technologies, Ansem and Qorvo—which account for a surprising global market share.Huawei has faced significant challenges in getting critical components because of the sanctions imposed by the United States which are primarily responsible for the inability of the Chinese company to launch 5G smartphones in the past three years. However, Mate 60 Pro, despite not being labeled a 5G device, exhibits mobile network speeds comparable to Apple’s latest 5G-enabled devices, offering a stable communication experience. This suggests Huawei has, over the past three years, overcome the 5G development and production limits due to the US sanctions by cooperating with domestic partners, and establishing an independent and controllable stable supply chain.Considering that Huawei has not explicitly marketed this device as a 5G smartphone, it is possible that it isyet to fully overcome some key core technological and componential shortcomings. For the time being, we can consider Huawei’s Mate 60 Pro as 4.99G. But when combined with the satellite communication capabilities of Mate 60 Pro, it is clear Huawei has been trying to find more advanced wireless communication solutions for smartphones and making significant progress in this attempt. This should be recognized as a remarkable endeavor, even a breakthrough.25.What do the underlined words “on par with” mean in Paragraph 1?A.as poor as.B.as good as.C.worse than.D.better than.26.Why was it tough for Huawei to develop a 5G smartphone three years ago?A.Its system design and fields needed to be updated.B.It only focused on the commercialization of 5G technology.C.It was unwilling to cooperate with high-tech giants in America.D.It lacked critical components mainly controlled by US high-tech giants.27.What does Paragraph 4 centre on?A.The US sanctions.B.Critical components.C.Apple’s latest 5G-enabled devices.D.Progress in Mate 60 Pro.28.What is the text mainly about?A.Huawei faced with significant challengesB.Huawei’s Mate 60 Pro—a 5G smartphoneC.Huawei’s Mate 60 Pro—a remarkable breakthroughD.Huawei leading in global 5G communication equipment(23-24高三上·江苏无锡·期末)Blue-light-filtering glasses (滤蓝光眼镜) have become an increasingly popular solution for protecting our eyes from electronic screens’ near-inescapable glow — light that is commonly associated with eyestrain (眼疲劳). In recent years they’ve even become fashion statements that are recognized by celebrities and ranked in style guides. But a recent review paper shows such glasses might not be as effective as people think.The paper, published last week in Cochrane Database of Systematic Reviews, analyzed data from previous trials that studied how blue-light-filtering glasses affect vision tiredness and eye health. The study’s authors found that wearing blue-light-filtering glasses does not reduce the eyestrain people feel after using computers.“It’s an excellent review,” says Mark Rosenfield, a professor at the State University of New York College of Optometry, who was not involved in the study. “The conclusions are no surprise at all. There have been a number of studies that have found exactly the same thing, that there’s just no evidence that blue-blocking glasses have anyeffect on eyestrain.” He adds that the new review reinforces the fact that there is virtually no evidence that blue-blocking glasses affect eyestrain despite them being specifically marketed for that purpose. As for using blue-light-filtering eyeglasses for eye health, for now, Rosenfield says, “there’s nothing to support people buying them”.The strain we may feel while staring at our phone or computer screen too long is likely to be caused by multiple factors, such as bad habits or underlying conditions, an associate professor of vision science at the University of Melbourne, Downie says. She argues that how we interact with digital devices contributes more to eyestrain than screens’ blue light does. Changing the frequency and duration of screen usage and distancing one’s eyes from the screens might be more important in reducing discomfort, Downie says. She adds that people who experience eyestrain should see a doctor to assess whether they have an underlying health issue such as far-sightedness or dry eye disease.29.What can we know about blue-light-filtering glasses from the text?A.They can improve eyesight.B.They may not reduce eyestrain.C.They can promote eye health.D.They can help to cure eye diseases.30.What can we infer from paragraph 2?A.A great many professors were involved in the study.B.Blue-blocking glasses on the market are harmful to eyes.C.The finding of the study comes as a surprise to the public.D.Data from previous trials help the study a lot.31.What does the underlined word “reinforces” mean in paragraph 3?A.Denies.B.Opposes.C.Strengthens.D.Evaluates.32.What should we do if we suffer from eyestrain according to Downie?A.Wear blue-light-filtering glasses.B.Have an examination in the hospital.C.Stop staring at the screen for ever.D.Focus on the frequency of phone usage.(2024·江苏连云港·一模)Not all birds sing, but several thousand species do. They sing to defend their territory and croon (柔声唱) to impress potential mates. “Why birds sing is relatively well-answered,” says Iris Adam, a behavioral neuroscientist. However, the big question for her was why birds sing so much.“As soon as you sing, you reveal yourself,” Adam says. “Like, where you are and where your territory is.” In a new study published in the journal Nature Communications, Adam and her co-workers offer a new explanation for why birds take that risk. They may have to sing a lot every day to give their vocal (发声的) muscles the regular exercise they need to produce top-quality songs. To figure out whether the muscles that produce birdsongsrequire daily exercise, Adam designed an experiment on zebra finches-the little Australian songbirds.She prevented them from singing for a week by keeping them in the dark cage almost around the clock. Light is what galvanizes the birds to sing, so she had to work to keep them from warbling (鸣叫). “The first two or three days, it’s quite easy,” she says. “But the longer the experiment goes, the more they are like, ‘I need to sing.’” At that point, she’d tap the cage and tell them to stop singing.After a week, the birds’ singing muscles lost half their strength. But Adam wondered whether that impacted the quality of songs. When she played a male’s song before and after the seven days of darkness, she couldn’t hear a difference. But when Adam played it to a group of female birds, six out of nine preferred the song that came from a male who’d been using his singing muscles daily.Adam’s conclusion shows that “songbirds need to exercise their vocal muscles to produce top-performance songs. If they don’t sing, they lose performance, and their songs get less attractive to females.” This may help explain songbirds’ continuous singing.It’s a good rule to live by, whether you’re a bird or a human-practice makes perfect, at least when it comes to singing one’s heart out.33.According to Iris Adam, birds sing so much to ______.A.warn other birds of risks B.produce more songsC.perform perfectly in singing D.defend their territory34.What does the underlined word “galvanizes” in Paragraph 3 mean?A.Prepares.B.Stimulates.C.Forbids.D.Frightens.35.What do we know about the caged birds in the experiment?A.They lost the ability to sing.B.They strengthened their muscles.C.Their songs showed no difference.D.Their songs became less appealing.36.What may Iris Adam agree with?A.The songbirds live on music.B.The songbirds are born singers.C.Daily exercise keeps birds healthy.D.Practice makes birds perfect singers.(23-24高三上·江苏扬州·期末)Sometimes called “Earth’s twin,” Venus is similar to our world in size and composition. The two rocky planets are also roughly the same distance from the sun, and both have an atmosphere. While Venus’s cold and unpleasant landscape does make it seem far less like Earth, scientists recently detected another striking similarity between the two, the presence of active volcanoes.When NASA’s Magellan mission mapped much of the planet with radar in the 1990sit revealed an。

2024年人教版中考英语阅读理解说明文十篇Most people have probably seen a movie about an AI (人工智能) tool or a robot (机器人) that has become so smart that it can control the world. At present, there are no such AI tools or robots. But scientists have been working to improve AI models. Some recent models can create realistic photos from a short written description. Others can recreate anyone’s voice based on a voice recording just a few seconds long.The AI tool that has got the most attention recently is ChatGPT, created by the company OpenAI. When asked a question, ChatGPT answers quickly in perfect sentences. It can make up stories and games, write articles, program computers, and much more. ChatGPT appears to be very intelligent (智能的). But in fact, ChatGPT is simply guessing—based on its training information—which word is most likely to come next, over and over again.In March, OpenAI developed a more powerful model, called GPT-4. GPT-4 can create and explain jokes, and pass tests that are difficult for humans. The rapid progress of recent AI models worries some people. In late March, many computer experts (专家) wrote a letter calling for a six-month pause (暂停) for any work on AI tools.The letter says AI companies race to create smart AI tools that no one can “understand, predict, or...control”.

(完整版)高考英语阅读理解科普类说明文4篇--较难(有答案)

高考英语说明文4篇1Here is an astonishing and significant fact: Mental work alone can’t makeus tire. It sounds absurd/əb'sɜːd/荒谬的. But a years ago, scientists tried to find out how long the human brain could labor without reaching a stage 阶段of fatigue /fə'tiːg/(疲劳). To the amazement of these scientists, they discovered that blood passing through the brain, when it is active, shows no fatigue at all! If we tooka drop of blood from a day laborer劳动者, we would find it fullof fatigue toxins /'tɒksɪn/ (毒素) and fatigue products. But if wetook blood from the brain of an Albert Einstein, it would show nofatigue toxins at the end of the day.So far as the brain is concerned, it can work as well and swiftly很快地at the end of eight or even twelve hours of effort as at the beginning. The brain istotally tireless. So what makes us tired?Some scientists declare that most of our fatigue comes from our mental and emotional(情绪的) attitudes. One of England’s most outstanding scientists, J.A. Hadfield, says, “The greater part of the fatigue from which we suffer is of mental origin /'ɒrɪdʒɪn/起源. In fact, fatigue of purely physical origin is rare.”Dr. Brill, a famous American scientist, goes even further. He declares, “One hundred percent of the fatigue of sitting worker in good health is due to emotional problems.”What kinds of emotions make sitting workers tired? Joy? Satisfaction?No! A feeling of being bored, anger, anxiety/æŋ'zaɪətɪ/焦虑, tenseness紧张, worry, a feeling of not being appreciated---those are the emotions that tire sitting workers. Hard work by itself seldom causes fatigue. We get tired because our emotions produce nervousness in the body.1. What surprised the scientists a few years ago?A. Fatigue toxins could hardly be found in a laborer’s blood.B. Albert Einstein didn’t feel worn after a day’s work.C. The brain could work for many hours without fatigue.D. A mental worker’s blood was filled with fatigue toxins.2. According to the author, which of the following can make sitting workers tired?A. Challenging mental work.B. Unpleasant emotions.C. Endless tasks.D. Physical labo3. What’s the author’s attitude towards the scientists’ idea?A. He agrees with them.B. He doubts them.C. He argues against them.D. He hesitates to accept them.4. We can infer from the passage that in order to stay energetic, sitting workers need to ________.A. have some good food.B. enjoy their workC. exercise regularlyD. discover fatigue toxins2They baby is just one day old and has not yet left hospital. She is quietbut alert /ə'lɜːt/(警觉). Twenty centimeters厘from her face researchershave placed a white card with two black spots on it. She stares at it carefully.A researcher removes the card and replaces it by another, this time with the spots differently spaced. As the cards change from one to the other, her gaze(凝视)starts to lose its focus — until a third, with three black spots,is presented. Her gaze returns: she looks at it for twice as long as she did at the previous card. Can she tell that the number two is different from three, just 24 hours after coming into the world?Or do newborns simply prefer more to fewer? The same experiment, but with three spots shown before two, shows the same return of interest when the number of spots changes. Perhaps it is just the newness 名,新奇? When slightly older babies were shown cards with pictures of objects (a comb, a key, an orange and so on), changing the number of objects had an effect separate from changing the objects themselves. Could it be the pattern that two things make, as opposed to three? No again. Babies paid more attention to squares moving randomly on a screen when their number changed from two to three,or three to two. The effect even crosses between senses. Babies who were repeatedly shown two spots became more excited when they then heard three drumbeats than when they heard just two; likewise (同样地)when the researchers started with drumbeats and moved to spots.5. The experiment described in Paragraph 1 is related to the baby’s__.A. sense of hearingB. sense of sightC. sense of touch D sense of smell6. Babies are sensitive to the change in______.A. the size of cardsB. the colour of picturesC. the shape of patternsD. the number of objects7. Why did the researchers test the babies with drumbeats?A. To reduce the difficulty of the experiment.B. To see howbabies recognize sounds.C. To carry their experiment further.D. To keep the babies’interest.8. Where does this text probably come from?A. Science fiction.B. Children’s literature.C. An advertisement.D.A science report3Last night’s meteor(流星) 英/'miːtɪə/ shower left many people in the community dissatisfied and demanding 苛求的;要求高的;吃力的answers. According to Gabe Rothsclild, Emerald Valley’s mayor市长, people gathered in thesuburbs /'sʌbɜːb/of the city, carrying heavy telescopes, expecting to watch the brightly burning meteors passing through the sky. What they found instead was a sky so brightene by the city’s lights that it darkened the light of the meteors passing overhead. “My family was so frustrated,” admitted town resident Duane Cosby, “We wanted to make this an unforgettable family outing, but it turned out to be a huge disappointments.”Astronomers- /ə'strɒnəmə/n. 天文学家--scientists who study stars and planets---- have beencomplaining about this problem for decades. They say that light pollution prevents them from seeing objects in the sky that they could see quite easily in the past. They call on people and the government to take measures to fightagainst it.There is yet a population besides professional and amateur /ˈæmətə(r)/美 /'æmə.tʃʊr/n. 爱好者star observers that suffers even more from light pollution. This population consists of birds, bats frogs, snakes, etc. For example, outdoor lighting severely affects migrating(迁徙的)birds. According to the International Dark-Sky Association. “100million birds a year throughout North America die in crashes 撞碎with lighted buildings and towers.”Countless more animals casualties(伤亡)result from the use of artificial lighting. Clearly, people enjoy the benefits of lighting their evenings, but some scientists think it can be harmful for humans, too. They worry that exposure to light while sleeping can increase pers on’s chances of getting cancer. Emerald Valley is only one community that is becoming aware of the negative effects of light pollution. For years, Flagstaff, Arizona/,æri'zəunə/美 /,æri'zəunə/n. 美国亚利桑那州, has enforced lighting regulations in its city in order to assist astronomers at the Lowell Observatory.英 /əb'zɜːvət(ə)rɪ/美 /əb'zɝvətɔri/n. 天文台;气象台;瞭望台Similar efforts have been made worldwide, and a movement isunderway 进行中的to remind us to turn off lights when we are not using them, so thatother creatures can share the night.9.It happened last night thatA. the city’s lights affected the meteor watchingB. the meteors flew past before being noticedC. the city light show attracted many peopleD. the meteor watching ended up a social outing10.

Saving wildlife is saving ourselvesB. Great efforts should be made to save energyC. Human activities should be environmentally friendlyD. New equipment should be introduced for space study4Almost every machine with moving parts has wheels, yet no one knows exactly when the first wheel was invented or what it was used for. We do know,however,that they existed over 5,500years ago in ancient Asia.The oldest known transport wheel was discovered in 2002 in Slovenia. It is over 5,100 years old. Evidence suggests thatwheels for transport didn't become popular for .while, though . This could be because animals did a perfectly good job of carryingfarming tools and humans around.But it could also be because of a difficult situation. While wheels need to roll on smooth surfaces, roads with smooth surfaces weren't going to be constructed until there was plenty of demand for them. Eventually, road surfaces did become smoother, but this difficult situation appeared again a few centuries later. There had been no important changes in wheel and vehicle design before the arrival of modern road design.In the mid-1700s,a Frenchman came up with a new design of road--a base layer (层)of large stones covered with a thin layer of smaller stones. A Scotsman苏格兰人improved on this design in the 1820s and a strong, lasting road surface became a reality. At around the same time, metal hubs英 /hʌb/美 /hʌb/n. 中心;毂;木片(the central part of a wheel)、came into being, followed by the Wheels were invented in 1967, sixty years after the appearance of tarmacked roads(泊油路).

高考英语阅读理解-说明文8篇真题训练-CAL-FENGHAI-(2020YEAR-YICAI)_JINGBIAN高考英语复习阅读理解专练说明文8篇Passage 1(2017北京,C)Measles(麻疹), which once killed 450 children each year and disabled even more, was nearly wiped out in the United States 14 years ago by the universal use of the MMR vaccine(疫苗). But the disease is making a comeback, caused by a growing anti-vaccine movement and misinformation that is spreading quickly. Already this year, 115 measles cases have been reported in the USA, compared with 189 for all of last year.The numbers might sound small, but they are the leading edge of a dangerous trend. When vaccination rates are very high, as they still are in the nation as a whole, everyone is protected. This is called“herd immunity”, which protects the people who get hurt easily, including those who can’t be vaccinated for medical reasons, babies too young to get vaccinated and people on whom the vaccine doesn’t work.But herd immunity works only when nearly the whole herd joins in. When some refuse vaccination and seek a free ride, immunity breaks down and everyone is in even bigger danger.That’s exactly what is happening in small neighborhoods around the country from Orange County, California, where 22 measles cases were reported this month, to Brooklyn, N.Y., where a 17-year-old caused an outbreak last year.The resistance to vaccine has continued for decades, and it is driven by a real but very small risk. Those who refuse to take that risk selfishly make others suffer.Making things worse are state laws that make it too easy to opt out(决定不参加)of what are supposed to be required vaccines for all children entering kindergarten. Seventeen states allow parents to get an exemption(豁免), sometimes just by signing a paper saying they personally object to a vaccine.Now, several states are moving to tighten laws by adding new regulations for opting out. But no one does enough to limit exemptions.Parents ought to be able to opt out only for limited medical or religious reasons. But personal opinions?Not good enough. Everyone enjoys the life-saving benefits vaccines provide, but they’ll exist only as long as everyone shares in the risks.1.The first two paragraphs suggest that.A.a small number of measles cases can start a dangerous trendB.the outbreak of measles attracts the public attentionC.anti-vaccine movement has its medical reasonsrmation about measles spreads quickly2.Herd immunity works well when.A.exemptions are allowedB.several vaccines are used togetherC.the whole neighborhood is involved inD.new regulations are added to the state laws3.What is the main reason for the comeback of measles?A.The overuse of vaccine.B.The lack of medical care.C.The features of measles itself.D.The vaccine opt-outs of some people.4.What is the purpose of the passage?A.To introduce the idea of exemption.B.To discuss methods to cure measles.C.To stress the importance of vaccination.D.To appeal for equal rights in medical treatment.Passage 2(2017天津,A)Suppose you’re in a rush, feeling tired, not paying attention to your screen, and you send an email that could get you in trouble.Realisation will probably set in seconds after you’ve clicked “send”. You freeze in horror and burn with shame.What to do?Here are four common email accidents, and how to recover.Clicking “send”too soonDon’t waste your time trying to find out if the receiver has read it yet. Write another email as swiftly as you can and send it with a brief title explaining that this is the correct version and the previous version should be ignored.Writing the wrong nameThe sooner you notice, the better. Respond quickly and briefly, apologising for your mistake. Keep the tone measured:don’t handle it too lightly, as people can be offended, especially if your error suggests a misunderstanding of their culture(i.e. incorrect ordering of Chinese names).Clicking “reply all”unintentionallyYou accidentally reveal(透露)to the entire company what menu choices you would preferat the staff Christmas dinner, or what holiday you’d like to take. In this instance, the best solution is to send a quick, light-hearted apology to explain your awkwardness. But it can quickly rise to something worse, when everyone starts hitting “reply all” to join in a long and unpleasant conversation. In this instance, step away from your keyboard to allow everyone to calm down.Sending an offensive message to its subjectThe most awkward email mistake is usually committed in anger. You write an unkind message about someone, intending to send it to a friend, but accidentally send it to the person you’re discussing. In that case, ask to speak in person as soon as possible and say sorry. Explain your frustrations calmly and sensibly—see it as an opportunity to clear up any difficulties you may have with this person.1.After realising an email accident, you are likely to feel .A.curiousB.tiredC.awfulD.funny2.If you have written the wrong name in an email, it is best to .A.apologise in a serious mannerB.tell the receiver to ignore the errorC.learn to write the name correctlyD.send a short notice to everyone3.What should you do when an unpleasant conversation is started by your “reply all”email?A.Try offering other choices.B.Avoid further involvement.C.Meet other staff members.D.Make a light-hearted apology.4.How should you deal with the problem caused by an offensive email?A.By promising not to offend the receiver again.B.By seeking support from the receiver’s friends.C.By asking the receiver to control his anger.D.By talking to the receiver face to face.5.What is the passage mainly about?A.Defining email errors.B.Reducing email mistakes.C.Handling email accidents.D.Improving email writing.Passage 3(2017天津,D)I read somewhere that we spend a full third of our lives waiting. But where are we doing all of this waiting, and what does it mean to an impatient society like ours?To understand the issue, let’s take a look at three types of “waits”.The very purest form of waiting is the Watched-Pot Wait. It is without doubt the most annoying of all. Take filling up the kitchen sink(洗碗池)as an example. There is absolutely nothing you can do while this is going on but keep both eyes fixed on the sink until it’s full. During these waits, the brain slips away from the body and wanders about until the water runs over the edge of the counter and onto your socks. This kind of wait makes the waiter helpless and mindless.A cousin to the Watched-Pot Wait is the Forced Wait. This one requires a bit of discipline. Properly preparing packaged noodle soup requires a Forced Wait. Directions are very specific.“Bring three cups of water to boil, add mix, simmer three minutes, remove from heat, let stand five minutes.”I have my doubts that anyone has actually followed the procedures strictly. After all, Forced Waiting requires patience.Perhaps the most powerful type of waiting is the Lucky-Break Wait. This type of wait is unusual in that it is for the most part voluntary. Unlike the Forced Wait, which is also voluntary, waiting for your lucky break does not necessarily mean that it will happen.Turning one’s life into a waiting game requires faith and hope, and is strictly for the optimists among us. On the surface it seems as ridiculous as following the directions on soupmixes, but the Lucky-Break Wait well serves those who are willing to do it. As long as one doesn’t come to rely on it, wishing for a few good things to happen never hurts anybody.We certainly do spend a good deal of our time waiting. The next time you’re standing at the sink waiting for it to fill while cooking noodle soup that you’ll have to eat until a large bag of cash falls out of the sky, don’t be desperate. You’re probably just as busy as the next guy.1.While doing a Watched-Pot Wait, we tend to.A.keep ourselves busyB.get absent-mindedC.grow anxiousD.stay focused2.What is the difference between the Forced Wait and the Watched-Pot Wait?A.The Forced Wait requires some self-control.B.The Forced Wait makes people passive.C.The Watched-Pot Wait needs directions.D.The Watched-Pot Wait engages body and brain.3.What can we learn about the Lucky-Break Wait?A.It is less voluntary than the Forced Wait.B.It doesn’t always bring the desired result.C.It is more fruitful than the Forced Wait.D.It doesn’t give people faith and hope.4.What does the author advise us to do the next time we are waiting?A.Take it seriously.B.Don’t rely on others.C.Do something else.D.Don’t lose heart.5.The author supports his view by.A.exploring various causes of “waits”B.describing detailed processes of “waits”C.analyzing different categories of “waits”D.revealing frustrating consequences of “waits”Passage 4(2017浙江,B)Getting less sleep has become a bad habit for most American kids. According to a new survey(调查) by the National Sleep Foundation, 51% of kids aged 10 to 18 go to bed at 10 pm orlater on school nights, even though they have to get up early. Last year the Foundation reported that nearly 60% of 7- to 12-year-olds said they felt tired during the day, and 15% said they had fallen asleep at school.How much sleep you need depends a lot on your age. Babies need a lot of rest: most of them sleep about 18 hours a day!Adults need about eight hours. For most school-age children, ten hours is ideal(理想的). But the new National Sleep Foundation survey found that 35% of 10- to 12-year-olds get only seven or eight hours. And guess what almost half of the surveyed kids said they do before bedtime?Watch TV.“More children are going to bed with TVs on, and there are more opportunities(机会) to stay awake, with more homework, the Internet and the phone,” says Dr. Mary Carskadon, a sleep researcher at Brown University Medical School. She says these activities at bedtime can get kids all excited and make it hard for them to calm down and sleep. Other experts say part of the problem is chemical. Changing levels of body chemicals called hormones not only make teenagers’ bodies develop adult characteristics, but also make it hard for teenagers to fall asleep before 11 pm.Because sleepiness is such a problem for teenagers, some school districts have decided to start high school classes later than they used to. Three years ago, schools in Edina, Minnesota, changed the start time from 7:25 am to 8:30 am. Students, parents and teachers are pleased with the results.1.What is the new National Sleep Foundation survey on?A.American kids’ sleeping habits.B.Teenagers’ sleep-related diseases.C.Activities to prevent sleeplessness.D.Learning problems and lack of sleep.2.How many hours of sleep do 11-year-olds need every day?A.7 hours.B.8 hours.C.10 hours.D.18 hours.3.Why do teenagers go to sleep late according to Carskadon?A.They are affected by certain body chemicals.B.They tend to do things that excite them.C.They follow their parents’ examples.D.They don’t need to go to school early.Passage 5(2017课标全国Ⅰ,C)Some of the world’s most famous musicians recently gathered in Paris and New Orleans to celebrate the first annual International Jazz Day. UNESCO(United Nations Educational, Scientific and Cultural Organization)recently set April 30 as a day to raise awareness of jazz music, its significance, and its potential as a unifying(联合)voice across cultures.Despite the celebrations, though, in the U.S. the jazz audience continues to shrink and grow older, and the music has failed to connect with younger generations.It’s Jason Moran’s job to help change that. As the Kennedy Center’s artistic adviser for jazz, Moran hopes to widen the audience for jazz, make the music more accessible, and preserve its history and culture.“Jazz seems like it’s not really a part of the American appetite,”Moran tells National Public Radio’s reporter Neal Conan.“What I’m hoping to accomplish is that my generation and younger start to reconsider and understand that jazz is not black and white anymore. It’s actually color, and it’s actually digital.”Moran says one of the problems with jazz today is that the entertainment aspect of the music has been lost.“The music can’t be presented today the way it was in 1908 or 1958. It has to continue to move, because the way the world works is not the same,”says Moran.Last year, Moran worked on a project that arranged Fats Waller’s music for a dance party,“just to kind of put it back in the mind that Waller is dance music as much as it is concert music,”says Moran.“For me, it’s the recontextualization. In music, where does the emotion(情感)lieAre we, as humans, gaining any insight(感悟)on how to talk about ourselves and how something as abstract as a Charlie Parker record gets us into a dialogue about our emotions and our thoughtsSometimes we lose sight that the music has a wider context,”says Moran,“so I want to continue those dialogues. Those are the things I want to foster.”1.Why did UNESCO set April 30 as International Jazz Day?A.To remember the birth of jazz.B.To protect cultural diversity.C.To encourage people to study music.D.To recognize the value of jazz.2.What does the underlined word“that”in paragraph 3 refer to?A.Jazz becoming more accessible.B.The production of jazz growing faster.C.Jazz being less popular with the young.D.The jazz audience becoming larger.3.What can we infer about Moran’s opinion on jazz?A.It will disappear gradually.B.It remains black and white.C.It should keep up with the times.D.It changes every 50 years.4.Which of the following can be the best title for the text?A.Exploring the Future of JazzB.The Rise and Fall of JazzC.The Story of a Jazz MusicianD.Celebrating the Jazz DayPassage 6(2016课标Ⅲ,C)If you are a fruit grower—or would like to become one—take advantage of Apple Day to see what’s around. It’s called Apple Day but in practice it’s more like Apple Month. The day itself is on October 21, but since it has caught on, events now spread out over most of October around Britain.Visiting an apple event is a good chance to see, and often taste, a wide variety of apples. To people who are used to the limited choice of apples such as Golden Delicious and Royal Gala in supermarkets, it can be quite an eye opener to see the range of classical apples still in existence, such as Decio which was grown by the Romans. Although it doesn’t taste of anything special,it’s still worth a try, as is the knobbly(多疙瘩的)Cat’s Head which is more of a curiosity than anything else.There are also varieties developed to suit specific local conditions. One of the very best varieties for eating quality is Orleans Reinette, but you’ll need a warm, sheltered place with perfect soil to grow it, so it’s a pipe dream for most apple lovers who fall for it.At the events, you can meet expert growers and discuss which ones will best suit your conditions, and because these are family affairs, children are well catered for with apple-themed fun and games.Apple Days are being held at all sorts of places with an interest in fruit, including stately gardens and commercial orchards(果园). If you want to have a real orchard experience, try visiting the National Fruit Collection at Brogdale, near Faversham in Kent.1.What can people do at the apple events?A.Attend experts’ lectures.B.Visit fruit-loving families.C.Plant fruit trees in an orchard.D.Taste many kinds of apples.2.What can we learn about Decio?A.It is a new variety.B.It has a strange look.C.It is rarely seen now.D.It has a special taste.3.What does the underlined phrase“a pipe dream”in Paragraph 3 mean?A.A practical idea.B.A vain hope.C.A brilliant plan.D.A selfish desire.4.What is the author’s purpose in writing the text?A.To show how to grow apples.B.To introduce an apple festival.C.To help people select apples.D.To promote apple research.Passage 7(2015课标Ⅰ,C)Salvador Dali(1904—1989)was one of the most popular of modern artists.The Pompidou Centre in Paris is showing its respect and admiration for the artist and his powerful personality with an exhibition bringing together over 200 paintings,sculptures,drawings and more.Among the works and masterworks on exhibition the visitor will find the best pieces,most importantly The Persistence of Memory.There is also L’Enigme sans Fin from 1938,works onpaper,objects,and projects for stage and screen and selected parts from television programmes reflecting the artist’s showman qualities.The visitor will enter the World of Dali through an egg and is met with the beginning,the world of birth.The exhibition follows a path of time and subject with the visitor exiting through the brain.The exhibition shows how Dali draws the viewer between two infinities(无限).“From the infinity small to the infinity large,contraction and expansion coming in and out of focus:amazing Flemish accuracy and the showy Baroque of old painting that he used in his museum-theatre in Figueras,”explains the Pompidou Centre.The fine selection of the major works was done in close collaboration(合作)with the Museo Nacional Reina Sofia in Madrid,Spain,and with contributions from other institutions like the Salvador Dali Museum in St.Petersburg,Florida.1.Which of the following best describes Dali according to Paragraph 1?A.Optimistic.B.Productive.C.Generous.D.Traditional.2.What is Dali’s The Persistence of Memory considered to be?A.One of his masterworks.B.A successful screen adaptation.C.An artistic creation for

word“contributions”in the last paragraph refer to?A.Artworks.B.Projects.C.Donations.D.Documents.Passage 8(2014课标Ⅰ,B)Passenger pigeons(旅鸽)once flew over much of the United States in unbelievable numbers.Written accounts from the 18th and 19th centuries described flocks(群)so large that they darkened the sky for hours.It was calculated that when its population reached its highest point,there were more than 3 billion passenger pigeons—a number equal to 24 to 40 percent of the total bird population in the United States,making it perhaps the most abundant bird in the world.Even as late as 1870 when their numbers had already become smaller,a flock believed to be 1 mile wide and 320 miles(about 515 kilometers)long was seen near Cincinnati.Sadly,the abundance of passenger pigeons may have been their undoing.Where the birds were most abundant,people believed there was an ever-lasting supply and killed them by the mercial hunters attracted them to small clearings with grain,waited until pigeons had settled to feed,then threw large nets over them,taking hundreds at a time.The birds were shipped to large cities and sold in restaurants.By the closing decades of the 19th century,the hardwood forests where passenger pigeons nested had been damaged by Americans’ need for wood,which scattered(驱散)the flocks and forced the birds to go farther north,where cold temperatures and spring storms contributed to their decline.Soon the great flocks were gone,never to be seen again.In 1897,the state of Michigan passed a law prohibiting the killing of passenger pigeons,but by then,no sizable flocks had been seen in the state for 10 years.The last confirmed wild pigeon in the United States was shot by a boy in Pike County,Ohio,in 1900.For a time,a few birds survived under human care.The last of them,known affectionately as Martha,died at the Cincinnati Zoological Garden on September 1,1914.1.In the 18th and early 19th centuries, passenger pigeons.A.were the biggest bird in

pigeons’.A.escapeB.ruinC.liberationD.evolution3.What was the main reason for people to kill passenger pigeons?A.To seek pleasure.B.To save other birds.C.To make money.D.To protect crops.4.What can we

英语阅读说明文Reading is a fundamental skill that is essential for academic and professional success. Among the various types of reading materials, expository texts are particularly important as they provide factual information and explanations on a wide range of topics. Expository texts are designed to inform, explain, or persuade the reader, and they are commonly found in textbooks, newspapers, magazines, and online resources.One of the key features of expository texts is their organizational structure. These texts often follow a logical sequence, such as chronological order, cause and effect, problem-solution, or compare and contrast. Understanding the organizational structure of an expository text can help readers navigate the information more effectively and extract the key ideas more efficiently. For example, when reading a text that follows a problem-solution structure, the reader can anticipate that the text will first present a problem and then provide potential solutions to that problem.Another important aspect of expository texts is the use of specificlanguage and terminology. Expository texts often contain technical or subject-specific vocabulary that may be unfamiliar to the reader. It is important for readers to be able to identify and understand these specialized terms in order to fully comprehend the content of the text. Strategies such as using context clues, consulting a dictionary or glossary, or identifying word roots and affixes can help readers overcome these linguistic challenges.In addition to understanding the organizational structure and vocabulary, effective reading of expository texts also requires the ability to identify the main ideas and supporting details. Expository texts typically have a central thesis or argument that is supported by evidence and examples. Readers need to be able to distinguish the main ideas from the supporting details in order to grasp the overall meaning and significance of the text.Furthermore, expository texts often present complex information and ideas that require critical thinking and analysis. Readers must be able to evaluate the credibility of the information, identify any biases or assumptions, and draw logical conclusions based on the evidence presented. This level of critical engagement is essential for understanding the nuances and implications of the content.One of the challenges of reading expository texts is the sheer volume of information that is often presented. Expository texts can belengthy and dense, covering a wide range of topics and concepts. Effective reading strategies, such as skimming, scanning, and close reading, can help readers navigate these complex texts and extract the most relevant and important information.In conclusion, reading expository texts is a crucial skill for academic and professional success. By understanding the organizational structure, vocabulary, and content of these texts, readers can effectively comprehend and analyze the information presented. Developing strategies for reading expository texts can help individuals become more informed, critical, and effective communicators in a variety of contexts.。

实验类说明文英语阅读理解Title: The Science of Experimentation: A Journey Through the Labyrinth of Discovery.In the realm of scientific exploration, experimentation stands as the litmus test of knowledge. It is the engine that drives our understanding of the natural world, pushing the boundaries of what is known and challenging the limits of human comprehension. This essay delves into the essence of experimentation, exploring its role in the scientific method, the ethics involved, and the impact it has on our world.The scientific method is a systematic approach to inquiry that relies heavily on experimentation. It begins with a hypothesis, a testable prediction about how the world works. This hypothesis is then subjected to rigorous testing through experiments designed to either confirm or refute it. The key to effective experimentation lies in its reproducibility: if other researchers can conduct the sameexperiment and achieve the same results, then the findings are more likely to be accepted as valid.Experiments range from the simple to the complex, each with its own unique challenges and rewards. In physics, for instance, experiments might involve particle accelerators and vacuum chambers to probe the fundamental structure of matter. In biology, experiments might involve culturing cells or manipulating genes to understand the intricacies of life. In each case, the scientist must meticulously control variables, ensuring that only the factor under investigation is altered.Ethics play a crucial role in experimentation, particularly when human subjects or animals are involved. The ethical principles of autonomy, non-maleficence, beneficence, and justice must be upheld at all times. Researchers must obtain informed consent from their subjects, ensure that no harm is done, strive to benefit their participants and society, and distribute the burdens and benefits of research fairly.The impact of experimentation is felt across all fields of science and beyond. It has led to groundbreaking discoveries in fields as diverse as medicine, technology, and social science. The development of vaccines, for example, has saved millions of lives through the rigorous testing of hypotheses about how the immune system can be harnessed to fight disease. The invention of the transistor, a key component of modern electronics, owes its existenceto experiments that explored the properties of semiconductors.In the social sciences, experiments have revealed insights into human behavior and decision-making. The field of psychology, for instance, has relied on experiments to understand the intricacies of human cognition, emotion, and motivation.
