201903. （2024•长安区•一模）     When wind blows through a bigleaf maple （大叶枫），paper-thin，wing-like seeds called samaras gently spin towards the ground.The fruit's tissue allows the wind to guide it further away from the tree.Inspired by the seeds，researchers designed a tiny，winged microchip，no larger than a grain of sand，that is powerful enough to monitor environmental pollution and airborne disease.
    Called the microflier，the microchip has no motor to push it forward in the air but instead was designed to catch the wind.To perfect the microchip's flying capability and shape，scientists took inspiration from the forms of various airborne seeds.The research team improved various designs until the microfliers flew slowly and more steadily than nature's samara seeds.The slower falling rate allows the microchip to keep flying for longer，which gives it more time to collect data and monitor air pollutants and airborne diseases.
    To perfect the microflier's flight，researchers took inspiration from children's pop-up books to create the three-dimensional wings.Usually，electronic microchips are flat，two-dimensional objects，but something flat won't take flight.To make the 3-D shape，John.
A．Rogers and his team built a stretched rubber base that the microchip rests on.The wings pop into flight mode when the rubber base is relaxed.
    The chip gathers data with sensors across its surface that can sense and monitor pH levels，test for heavy metals or chemicals，and track air pollution.An antenna （天线） on the microflier then sends all the collected data to a computer or phone.Rogers and his team are planning to test out the electronic chips soon by dropping thousands of the chips in a field.The microfliers will change color depending on the number of heavy metals present in the field where they land.A drone will then fly over the area and take photos of the microflier's colors，allowing researchers to map out the pollutants.
    Rogers and his team also designed the microchips to break down over time to prevent environmental pollution.

（1）What is the winged microchip designed to do？
A．Guide seeds from the tree.
B．Prevent airborne diseases.
C．Keep track of air qualities.
D．Catch the wind to fly away.
（2）What do paragraph 2 and 3 focus on？

201654. （2025•高新一中•十模）     Autonomous systems，including self-driving cars and robots，are rapidly becoming integral to our daily lives.However，these systems often face challenges in visual recognition across various environments such as bright sunlight，low light，or when objects mix into complex surroundings.Remarkably，nature might already hold the answer to this problem.
    Cats are known for their excellent vision in both bright and dark settings.Their eyes are uniquely adapted for different lighting conditions：their pupils adjust to reduce brightness during the day，while at night，these pupils widen to allow more light in.Additionally，a reflective layer behind their retinas（视网膜），known as the tapetum lucidum，improves their night vision.
    Inspired by the impressive abilities of cat vision，a team of researchers led by Professor Young Min Song at the Gwangju Institute of Science and Technology（GIST） has developed a new vision system using advanced lenses（透镜） and sensors modeled after cats' eyes.This system includes a slit-shaped aperture（狭缝状光圈） that，like a cat's daily pupil，blocks extra light and sharpens focus on essential objects.It also has a reflective layer similar to the tapetum lucidum，enhancing visibility in low-light conditions.
    Published in Science Advances，this research marks a significant step forward in artificial vision，showing improved object detection and recognition abilities."Traditional robotic cameras struggle to identify objects in busy backgrounds，especially under changing light conditions，"Prof.Song explains."Our design enables robots to ignore unimportant details，concentrating only on key objects."Additionally，the system is energy-efficient，as it relies more on lens design than on heavy computer processing.
    This innovative technology opens up exciting potential for real-world applications，potentially transforming robotic vision.With this advanced system，security robots and self-driving vehicles can move through complex environments and perform precise tasks with greater accuracy."From search-and-rescue missions to industrial monitoring，these advanced robotic eyes can assist or even replace human efforts in critical situations，"Prof.Song highlights.

（1）How do cats' eyes adapt to different lighting conditions？

201921. （2024•临潼区•二模）     Artificial intelligence models can trick each other into disobeying their creators and providing banned instructions for making drugs，or even building a bomb，suggesting that preventing such AI "jailbreaks" is more difficult than it seems.
    Many publicly available large language models （LLMs），such as ChatGPT，have hard-coded rules that aim to prevent them from exhibiting racial or sexual discrimination，or answering questions with illegal or problematic answers — things they have learned from humans via training data.But that hasn't stopped people from finding carefully designed instructions that block these protections，known as "jailbreaks"，making AI models disobey the rules.
    Now，Arush Tagade at Leap Laboratories and his co-workers have found a process of jailbreaks.They found that they could simply instruct one LLM to convince other models to adopt a persona （角色），which is able to answer questions the base model has been programmed to refuse.This process is called "persona modulation （调节）".
    Tagade says this approach works because much of the training data consumed by large models comes from online conversations，and the models learn to act in certain ways in response to different inputs.By having the right conversation with a model，it is possible to make it adopt a particular persona，causing it to act differently.
    There is also an idea in AI circles，one yet to be proven，that creating lots of rules for an AI to prevent it displaying unwanted behaviour can accidentally create a blueprint for a model to act that way.This potentially leaves the AI easy to be tricked into taking on an evil persona. "If you're forcing your model to be good persona，it somewhat understands what a bad persona is，" says Tagade.
    Yinzhen Li at Imperial College London says it is worrying how current models can be misused，but developers need to weigh such risks with the potential benefits of LLMs. "Like drugs，they also have side effects that need to be controlled，" she says.

（1）What does the AI jailbreak refer to？
A．The technique to break restrictions of AI models.
B．The initiative to set hard-coded rules for AI models.
C．The capability of AI models improving themselves.
D．The process of AI models learning new information.
（2）What can we know about the persona modulation？
A．It can help AI models understand emotions.
B．It prevents AI learning via online conversations.
C．It can make AI models adopt a particular persona.
D．It forces AI models to follow only good persona.
（3）What is Yinzhen Li's attitude towards LLMs？
A．Unclear.
B．Cautious.
C．Approving.
D．Negative.
（4）Which can be a suitable title for the text？
A．LLMs：Illegal Learning Models
B．LLMs：The Latest Advancement
C．AI Jailbreaks：A New Challenge
D．AI Jailbreaks：A Perfect Approach

201635. （2025•铁一中学•六模）     Artificial intelligence-or AI-is the computer code that allows a machine to do something that normally requires a human brain.On TikTok，for instance，AI sorts the posts so that the first ones you see are likely to be those you'd prefer.But before an AI can do any of that，developers must train it.
    While a small percentage of AI systems are trained using low-emission sources such as solar，hydro，or nuclear power，the overwhelming majority still depend on the conventional energy mix supplied by national grids.In many parts of the world，that energy mix leads to significant carbon emissions，prompting growing concerns over the environmental footprint of energy-hungry AI models.
    Language-processing AI systems develop their abilities by devouring large collections of written content，which may include everything from online articles to digitized books in multiple languages.Training them takes extended time and constant system activity，often depending on powerful machines running without interruption.To translate between English and Chinese，for example，an AI model may deal with millions or even billions of translated books and articles.In this way，it learns which words and phrases match.Later，when given a new text，it recommends its own translation.
    To compare how different activities affect the climate，researchers often combine the impacts of all greenhouse gases into what they call CO₂ equivalents.In 2019，researchers calculated the impact of developing an AI model named Transformer.It released a whopping 626，000 pounds of carbon dioxide equivalents.That's equal to the greenhouse gases that would be poured by five American cars from when they were made to when they were junked.
    Today，most AI development happens at data centers.These computer-filled buildings account for some 2 percent US electricity use and 1 percent of global energy use.As AI models grow larger and more computationally demanding，these figures are expected to rise.Some experts have sounded the alarm，warning that the unchecked energy appetite of such systems may soon pose a significant threat to global sustainability efforts.With rising energy demands，AI's expansion signals more than just innovation-where it leads remains uncertain.

（1）What is AI training mainly energized by？
A.Fossil fuels.
B.Clean resources.
C.Nuclear energy.
D.Greenhouse gases.
（2）What do we know about the language-processing AI systems？
A.They skip digitalized materials.
B.They are domain-specific.
C.They may outperform human translators.
D.They are energy -intensive.
（3）Why does the author mention Transformer in paragraph 4？
A.To suggest AI emissions match those from big polluters.
B.To explain how AI handles language in training sessions.
C.To show AI is possibly outpacing traditional industries.
D.To stress the environmental cost of AI development.
（4）What does the author imply in the last paragraph？
A.AI's expansion may overwhelm data center systems.
B.The energy footprint of AI deserves close attention.
C.AI's development raises social and moral concerns.
D.Cutting AI-related emissions calls for public efforts.

201673. （2024•师大附中•八模）     Lately，it's felt like technological change has entered an incredible speed.Companies like OpenAI and Google have unveiled new Artificial Intelligence systems with incredible capabilities，making what once seemed like science fiction an everyday reality.It's an era that is raising big，existential questions for us all，about everything from the future of human existence to the future of human work.
    "Things are changing so fast，"says Erik Brynjolfsson，a leading，technology-focused economist based at Stanford University.As he notes，this new wave of technological change looks like it could be pretty different.Unlike before，experienced and skilled workers benefited mostly from AI technology.In this new wave，it's the less experienced and less skilled workers who benefit the most."And that might be helpful in terms of closing some of the inequality that previous technologies actually promoted，" Brynjolfsson says.So one benefit of intelligence machines is-maybe-they will improve the know-how and smarts of low performers，thereby reducing inequality.
    But it's also possible that Al could lower the profit of the experienced，smart，or knowledgeable ones.AI could reduce inequality by bringing the bottom up，and it could also reduce inequality by bringing the top and middle down.
    Of course，as Erik put，it's also possible that Al could end up increasing inequality even more.For one，it could make the Big AI companies，which own these powerful new systems，wildly rich.It could also empower business owners to replace more and more workers with intelligent machines.And it could kill jobs for all but the best of the best in various industries，who keep their jobs because maybe they're superstars or because maybe they have seniority.
    The effects of AI，of course，are still very much being studied and these systems are evolving fast，so this is just an assumption.This machine intelligence could upend much of the previous thinking on which kinds of jobs will be affected by automation.

（1）What do the underlined words "the know-how and smarts" mean in paragraph 2？
A．Experience and intelligence.
B．Skills and potential.
C．Capacity and experience.
D．Outlook and talents.
（2）Who will gain more in this new AI era？
A．The senior with high rank.
B．The inexperienced with low competence.
C．The learned with great credit.
D．The poor with practical skills.
（3）Which statement will Erik probably agree with？
A．The fast development of AI will promote the division of inequality.
B．AI Giants will be the dominator in the future world of new AI systems.
C．The best of all walks of life will survive the competition against AI systems.
D．Lower rank workers with little knowledge are bound to be abandoned by employers.
（4）Which of the following is the best title for the text？
A．The Fast Growth of the Artificial Intelligence
B．The Influence of the AI Inequality
C．The Impact of the Artificial Intelligence
D．The Future of the AI Generation

201884. （2024•周至县•一模）      Since 2001，robotic tools have revolutionized the practice of surgery.They have greatly reduced the stress and physical demands normally placed on surgeons and have made certain procedures possible.
    One example is "keyhole surgery"，or minimally invasive （微创） surgery，which normally requires surgeons to stand at awkward angles and make difficult movements with their hands to make a cut inside the patient.But in June 2022，surgeon James Ansell used 3 D glasses and two sticks to control four robotic arms to perform a procedure to remove a cancerous tumor. "My colleague said...that this feels like cheating，" Ansell said to The Guardian.
    Another area of surgery that has had major technological breakthroughs in recent years is telesurgery.Normally，telesurgery relies on a wired connection due to concerns of harming the patient should a wireless connection drop during surgery，but China made several advancements in wireless telesurgery based on 5 G technology.
    China achieved the first 5 G-based remote operation in March 2019 involving a brain surgery procedure between a surgeon in Sanya and a patient in Beijing，a distance totaling nearly 3，000 kilometers.More recently，a team of surgeons successfully completed remote micron-level eye surgery on rabbits located in a different city.The rabbits were at the Sun Yat-sen University in Guangzhbù，Guangdon g province，whereas the surgical team who operated on them via a 5 G robot were at the Hainan Eye Hospital in Haikou，Hainan province.
    Looking to the future，people hope that remote surgery could become commonplace to help heal injured soldiers on the battlefield while keeping surgeons at a safe distance.Some even believe that robotic systems，combined with AI，could one day exceed human surgeons.
    But，given current technological limitations and the high costs of these robots which can cost millions of dollars，the complete robot takeover of surgery may still be a while off.

（1）What does the "keyhole surgery" example intend to show？
A．Great complexity of robotic surgery.
B．Physical challenges surgeons face.
C．Surgical progress enabled by robotic tools.
D．Urgent need for advanced 3 D technology.
（2）What significant achievement did China make in the field of telesurgery？
A．Achieving remote surgery using a wired connection.
B．Completing successfully remote eye surgery on humans.
C．Conducting a 5 G-based remote operation on rabbits overseas.
D．Performing the first wireless brain surgery with 5 G technology.
（3）What can be inferred from the text about robots in the medical field？
A．They are quite affordable.
B．They are currently in high demand.
C．They have not been widely used.
D．They have gone beyond human capabilities.
（4）What is a suitable title for the text？
A．Robotic Surgery Uses 5 G Technology
B．Keyhole Surgery Benefits Human Beings
C．Autonomous Robot Achieves Great Progress
D．Medical Robotics Revolutionizes Surgery Method

201950. （2023•周至县•三模） Without cracking a single textbook，without spending a day in medical school，the co-author of a preprint study correctly answered enough questions that it would have passed the real US Medical Licensing Examination.But the test-taker wasn't a member of Mensa or a medical specialist；it was the artificial intelligence ChatGPT.The tool，which was created to answer user questions in a conversational manner，has generated so much buzz that doctors and scientists are trying to determine what its limitations are and what it could do for health and medicine.
   The medical licensing exam is generally considered one of the toughest of any profession because it not only tests basic science，medical knowledge，but also assesses clinical reasoning，ethics （道德观念），critical thinking and problem-solving skills.
   The AI passed all the parts of the exam without any specialized training，showing a high level of insight in its explanations.This greatly impressed Dr.Victor Tseng，a medical director of the California-based group and a co-author of the study. "Googling the answer is very difficult，" he explained. "Because there're a lot of red herrings on the Internet.It might take hours to get an accurate answer." But ChatGPT was able to do it within five seconds.
   The results of the medical licensing exam study were even written up with the help of ChatGPT.However，the journal Nature created guidelines that said no such program could be credited as an author because "any authorship carries with it accountability for the work，and AI tools cannot take such responsibility." Actually，AI is only as good as the information it's fed，and with so much inaccurate information available online about things like COVID-19 vaccines，it could use that to generate inaccurate results.
   Tseng said he ultimately thinks ChatGPT can enhance medical practice，but won't replace doctors.Tseng's group will continue to test it to learn why it creates certain errors and what other ethical factors need to be put in place before using it for real.
   "AI is here.The doors are open，" Tseng said. "I firmly believe that it will actually make me and make us as physicians and providers better."

（1）What can ChatGPT possibly do according to paragraph 1？
A．Study in medical school.
B．Start an online conversation.
C．Conduct a study independently.
D．Pass a challenging examination.
（2）What does underlined words "red herrings" in paragraph 3 refer to？
A．Appealing topics.
B．Efficient helpers.
C．Hidden resources.
D．Distracting facts.
（3）According to Nature，ChatGPT can't be listed as an author because        .
A．it has invented all the data based on inaccurate information
B．it doesn't actively create and is not responsible for the work
C．it doesn't have a bank account and can't receive payment
D．it has failed to demonstrate problem-solving skills
（4）What is Tseng's attitude towards the future of ChatGPT？
A．Interested yet doubtful.
B．Disinterested and calm.
C．Confident yet cautious.
D．Critical and disappointed.

201826. （2024•西安中学•九模） In February of 1942，Mexican farmer Dionisio Pulido thought he heard thunder coming from his cornfield.However，the sound wasn't coming from the sky.The source was a large smoking break sending out gas and pushing out rocks.This opening would come to be known as the volcano Paricutin，and over the next 9 years，its lava and ash would cover over 200 square km.But where did this new volcano come from，and what caused its unpredictable eruption？
   One of the most common causes of an eruption is an increase in magmastatic（静磁）pressure.Magma（岩浆）contains various elements and compounds.At high enough concentrations，compounds like water or sulfur（硫）form high-pressure gas bubbles.When these balls of gas reach the surface，they can burst with the force of a gunshot.And when millions of bubbles explode，the energy can send ash into the air.But before they pop or burst，they act like bubbles of CO₂ in a shaken soda.
   Not all eruptions are due to rising magmastatic pressure- sometimes the weight of the rock above can become dangerously low.Landslides can remove massive quantities of rock from atop a magma chamber or room，dropping the pressure and instantly touching off an eruption.This process is known as "unloading" and it's been responsible for numerous eruptions，including the sudden explosion of Mount St.Helens in 1980.But unloading can also happen over longer periods of time due heating ice or melting glaciers.In fact，many geologists are worried that glacial melt caused by climate change could increase volcanic activity.
   Unfortunately，knowing what causes eruptions doesn't make them easy to predict.While scientists can roughly determine the strength and weight of the Earth's crust（地壳），the depth and heat of magma chambers makes measuring changes in magmastatic pressure very difficult.But volcanologists are constantly exploring new technology to overcome this rocky field.Advances in thermal imaging（热成像）have allowed scientists to detect underground hotspots.Spectrometers can analyze gases escaping magma.Hopefully，these tools will help us better understand these gas breaks and their explosive eruptions.

（1）Why does the author mention the story of a farmer in the first paragraph？
A．To show the power of volcano eruption.
B．To introduce the topic.
C．To introduce the volcano Paricutin.
D．To explain the reason.

201968. （2023•长安区•一模） Electronic sensors built into paper could be used in a range of ways from information storage to touch screens and more.
   Electronic sensors built into cartons（纸盒）may make it easier to tell when it's time to throw out rotten milk or orange juice.And that's just the start.At least that's the goal for researchers working on putting electronics into paper.They're trying to figure out how to combine the flexibility，low-cost and recyclability of paper with the information-carrying ability of electronics.
   Daniel Torbjork，a physics graduate student in Finland，has been working on the problem.He's published a review of the field in the journal Advanced Materials.
   Much research has been focused in this area.While most electronic applications require patterned conducting structures，conductive paper could be used in applications such as energy storage devices，sensors，electric heaters and others，according to Torbjork.
   "You could even have some interactive functions in magazines，" Torbjork said，"You could put a simple game in a package.If you want a touch screen，press a button and then something happen.Sensors in paper could tell us when something has gone bad."
   Additional applications，such as information storage and security paper，have been suggested for magnetic papers containing magnetite.In Massachusetts，researchers have figured out how to post a video of such a device put into a paper airplane.
   German researchers have also put electronic chips in paper bank notes to defend counter-feiters（造伪币者）.Paper is a good material but printing electronics also requires low-cost manufacturing.As many US and European paper makers lose market share to cheaper paper from China，these big paper companies are looking for added value products.That's where electronic paper devices could make a difference.
   "The major obstacles are paper's large surface roughness and chemical impurities." Torbjork says.But others in the field think that electronic sensors in paper are still far from the consumer marketplace.
   "I don't think it's going to happen." said Roy Horgan. "You need a conductive surface.It could be 10 years out.What we are looking for are solutions that you can commercialize today."
   Solar Print is partnering with Italian automaker Fiat to develop a unique auto-glass with tiny photostatic cells（光电）that can capture electricity from the sun.In the meantime，using paper to conduct electricity is still a "blue-sky" project.
   "I would love to see someone prove me wrong，because that means that it's actually happening." Horgan said. "If someone comes up with conductive paper，then that's a very interesting technology."

（1）Putting electronics into paper will        .
A．cut the cost and impurity of paper
B．depend on flexible conductive structure
C．help consume rotten milk or orange juice
D．combine the advantages of paper and electronics
（2）Paragraphs 4 to 7 mainly talk about the         of the conductive paper.
A．theories
B．structures
C．practical use
D．design process
（3）Some paper makers welcome the new technology probably because it will         .
A．add more value to paper
B．make the paper smoother
C．put an end to fake money
D．improve the printing technology
（4）From the passage，we know that Roy Horgan        .
A．has a burning desire to make a great profit
B．started a "blue-sky" project to study paper
C．is not confident about the conductive paper
D．showed much interest in Solar Print industry

201693. （2024•西工大附中•模拟） California has lost half its big trees since the 1930s，according to a study to be published Tuesday and climate change seems to be a major factor．
    The number of trees larger than two feet across has declined by 50 percent on more than 46，000 square miles of California forests，the new study finds．No area was spared or unaffected，from the foggy northern coast to the Sierra Nevada Mountains to the San Gabriels above Los Angeles．In the Sierra high country，the number of big trees has fallen by more than 55 percent；in parts of southern California the decline was nearly 75 percent．
   Many factors contributed to the decline，said Patrick Mclntyre，an ecologist who was the lead author of the study．Woodcutters targeted big trees．Housing development pushed into the woods．Aggressive wildfire control has left California forests crowded with small trees that compete with big trees for resources（资源）．
   But in comparing a study of California forests done in the 1920s and 1930s with another one between 2001 and 2010，Mclntyre and his colleagues documented a widespread death of big trees that was evident even in wildlands protected from woodcutting or development．
    The loss of big trees was greatest in areas where trees had suffered the greatest water shortage．The researchers figured out water stress with a computer model that calculated how much water trees were getting in comparison with how much they needed，taking into account such things as rainfall，air temperature，dampness of soil，and the timing of snowmelt（融雪）．
   Since the 1930s，Mclntyre said，the biggest factors driving up water stress in the state have been rising temperatures，which cause trees to lose more water to the air，and earlier snowmelt，which reduces the water supply available to trees during the dry season．

（1）What is the second paragraph mainly about？
A．The seriousness of big-tree loss in California．
B．The increasing variety of California big trees．
C．The distribution of big trees in California forests．
D．The influence of farming on big trees in California．
（2）Which of the following is well-intentioned but may be bad for big trees？
A．Ecological studies of forests．
B．Banning woodcutting．
C．Limiting housing development．
D．Fire control measures．
（3）What is a major cause of the water shortage according to Mclntyre？
A．Inadequate snowmelt．
B．A longer dry season．
C．A warmer climate．
D．Dampness of the air．
（4）What can be a suitable title for the text？
A．California's Forests：Where Have All the Big Trees Gone？
B．Cutting of Big Trees to Be Prohibited in California Soon．
C．Why Are the Big Trees Important to California Forests？
D．Patrick Mclntyre：Grow More Big Trees in California

201845. （2024•西安一中•二模）     A carbon footprint is only one component of the broader ecological footprint.An ecological footprint compares the population's consumption of resources and land with the planet's ability to regenerate.The Earth's ecological footprint is currently 23 percent over capacity.It takes about one year and two months to regenerate what we consume in a year.
    Carbon footprints help people keep track of changes.Because footprints quantify an amount of carbon that increases or decreases based on energy use，they let people know that a new hybrid car or home insulation （隔离） helps.Transportation accounts for 33 percent of CO₂ emissions in the United States，so many people try to lower their mileage （里程）.Some walk or bike whenever possible；others take public transport.Home energyuse accounts for 21 percent of U.S.CO₂ emissions，so it helps to have an efficient home.Setting the thermostat （恒温器） at a moderate temperature and installing double-paned windows lowers energy costs.
    Of course，individual efforts can go only so far.Cutting CO₂ and other greenhouse gases down to safer levels requires significant government regulation.Lessening carbon footprints does let people see where they are and how they can change.Those who want to accept personal responsibility for their emissions can track their own reductions and change their habits.
    Because carbon calculators ask for only rough estimates，it's easy for investigators to approximate the footprints of celebrities and politicians.Analysts hope to uncover high-profile figures，especially those who promote environmentalism.Although performer Madonna and other celebrities have been accused of flying frequently，former vice president Al Gore has drawn the harshest accusations.The Gores' spokesperson did not deny that but emphasized that the couple subscribes to green power.

（1）How long can the Earth produce what we need in a year？        ?
A.2 months.
B.12 months.
C.14 months.
D.23 months.
（2）What is the second paragraph mainly about？        ?
A.Why people are worried about CO₂ emissions.
B.How individuals can help to lower CO₂ emissions.
C.Where most CO₂ emissions come from in the United States.
D.What measures have been taken to cut down CO₂ emissions.
（3）What is still needed to cut greenhouse gases down to safer levels？        ?
A.The participation of the public.
B.The development of new equipment.
C.The changes of our living habits.
D.The powerful efforts of the government.
（4）Why do investigators estimate the footprints of famous people easily？        ?
A.Because they have mastered methods.
B.Because it doesn't call for much accuracy.
C.Because famous people are easy to approach.
D.Because new technology has advanced greatly.

201864. （2024•西安一中•三模）     The 2023 EF English Proficiency （水平） Index （EPI） that measures English language ability worldwide shows a worrying problem about English language proficiency.The index is based on test results from 2.2 million people in 113 countries.
    Results were reported for the first time in 2015.Since then，the English proficiency of young people has decreased by 89 points.The EPI defines young people as being 18 to 20 years of age，and it notes that they are mostly stable with big decreases in a few large countries.India，Indonesia and Mexico showed the largest ability decreases among youth.
    The report noted that the decrease appears to have taken place when the COVID-19 pandemic impacts normal education.There has been a decrease in Mexico for nearly 10 years.However，working adults，about 26 years old and older，have been improving their English since 2015.It is still widely acknowledged that the value of a shared language is most recognized in the workplace.English creates possibilities for individuals and productivity for organizations.
    Results also show a difference between men and women，which is called a gender gap.Men's English ability has improved by 14 points since 2015，while women's has decreased by 19 points.The lack of women in international jobs is one reason for the gender gap.But the gender gap among those aged 18 to 25 might demonstrate a problem caused by educational systems themselves or a social problem schools are failing to address.
    There are different opinions about why the decrease exists.Many people think artificial intelligence （or AI） tools could also be a key reason.Jeannie Tse is a country manager at EF Hong Kong and Macau.He thinks that while AI has changed the way young people work and learn，the importance of schools，teachers and face-to-face instruction remains. "I don't believe that AI can completely replace language learning，but educators can use AI to enhance language learning methods，" said Jeannie Tse.

（1）Why are working adults trying to improve their English？        ?
A．To increase their income and knowledge.
B．To be involved in better working environment.
C．To obtain more chances and better working efficiency.
D．To create a harmonious working environment for themselves.
（2）What can we learn from paragraph 4？        ?
A．Most women don't like international jobs.
B．Educational systems contribute to the gender gap in English proficiency.
C．Women's English proficiency decreases with age.
D．There widely exists the phenomenon of discrimination against women.
（3）What's Jeannie Tse's attitude to the role of AI and face-to-face teaching？        ?
A．Objective.
B．Positive.
C．Uncertain.
D．Uncaring.
（4）What is a suitable title for the text？        ?
A．Young People's Attitudes towards English Vary
B．English Learning Has Become a Burden Worldwide

201865. （2024•西安一中•三模）     Fossils （化石），the preserved remains of ancient life，serve as windows into the Earth's rich history.The formation of the fossils is a wonderful journey that unfolds over vast stretches of time，catching good views of the diversity of life that once lived on our planet.
    The journey often starts with the death of an organism in a specific environment.Whether it's a plant，animal or microscopic organisms，the key factor lies in whether the remains are quickly buried.This initial step is critical to protect the organism from its enemies and environmental factors that could lead to breakdown.
    As the remains are buried，they experience layers of sediment （沉积层）.Over time，more layers gather，pressing the lower sediments.This process，known as sedimentation，plays a crucial role in preserving the remains by creating a protective environment that protects them from being destroyed.
    Mineralization is also a key period in the fossilization process.It involves the infiltration （过滤） of minerals into the organic tissues of the buried remains.Groundwater，rich in minerals moves through these layers.The minerals replace the original organic material，transforming the remains into rock-like forms.
    Sometimes，fossilization goes beyond mineralization to a process called petrification.Petrified fossils occur when the organic material is entirely replaced by minerals，often resulting in a good copy of the original organism.This transformation can preserve complex details，such as the skeletal features of animals.For softer organisms or parts like leaves or feathers，the fossilization process involves pressure.Under the weight of sediments，these delicate structures flatten but leave behind detailed imprints.
    The final step in the journey comes when geological processes expose the fossilized remains.Archaeologists then unearth these treasures，revealing the secrets of Earth's ancient inhabitants.This scientific exploration contributes to our understanding of evolution，biodiversity，and the ever-changing landscapes that have shaped the history of life on our planet.

（1）What is the role of fossils in the modern times？        ?
A．To help protect our environment.
B．To help explore the function of the Earth.
C．To enhance knowing the long history of the universe.
D．To provide an insight into the diverse life forms.
（2）Which of the following is the first step of fossilization？        ?
A．The quick pressure caused by rocks.
B．The quick transformation of the remains.
C．The rapid burial of the remains.
D．The mix of groundwater and minerals.
（3）How can a good copy of organisms form？        ?
A．By fossils petrified when minerals replace the organic material.
B．By groundwater moving through them.
C．By accumulating more pressure on them.
D．By creating a protective environment.
（4）What's the text mainly about？        ?
A．The importance of fossils.
B．The process of fossilization.
C．The evolution of ancient animals.
D．The preservation of the remains.

201883. （2024•周至县•一模）     The fishermen of Senegal have joined forces to protect one of the ocean's most endangered species—the sea turtle，a classic case of "poacher turned gamekeeper".
    The coastal waters of Senegal in West Africa are home to several species of sea turtles which are all beautiful creatures but are affected by pollution，poaching and even fishing nets.
    "Once we were the biggest eaters of turtles，now we have become their biggest protectors，" said Abdou Karim Sall，a fisherman who led the Management Committee for the Marine Protected Are （MPA）of Joal-Fadiouth.
    The Joal-Fadiouth MPA，covering about 174 square kilometers，was founded in 2004，and it's upheld by the government，local authorities and several associations.It is an area aimed at protecting mar in e ecosystem，habitats and species，including endangered species like the sea turtle.Its benefits are obvious：maintaining biodiversity，increasing fish catches on fishing grounds，as well as economic development.
    For a long time，Sall has been working to raise local awareness of sea turtle protection. "Even former turtle sellers have been 'changed' by receiving three small boats to take tourists to sea，" he said.Instead of strict restrictions，the Joal-Fadiouth MPA has been trying to educate local communities about the economic benefits so that they would join the project. "It's after they are told： 'It's an endangered species'，" Sall said.
    Local residents have also set out to protect the nests.During summer and fall，a few dozen turtles may stop to lay eggs on the beaches of Joal-Fadiouth.MPA agents and village volunteers pro test their nests with fences. "People come at 6 a.m.so that other animals do not take the young." said Sall.
    Sall added the number of turtles had decreased by about 30% in the past 20 years，and chances of survival of a young turtle were no higher than one in a thousand.But the fisherman-conservator agreed， "Awareness has not worked 100%."

（1）What does the underlined word "upheld" in Paragraph 4 mean？
A.Hurt.
B.Ignored.
C.Supported.
D.Paused.
（2）Which of the following is the measure taken by the Joal-Fadiouth MPA to protect sea turtles？
A.Building more nests for turtles to lay eggs.
B.Placing strict restrictions to educate the communities.
C.Providing different means of transportation for turtle sellers.
D.Publicizing the economic benefits of the project.
（3）What will most probably be talked about in the following paragraph？
A.The mistakes the MPA has made.
B.The danger sea turtles still face from fishermen.
C.The argument about the Marine Protected Area.
D.The benefits brought by the Marine Protected Area.
（4）What is the main idea of the text？
A.Fishermen of Senegal have joined together to protect sea turtles.
B.Sea turtles in Senegal are endangered because of human activities.
C.The situation of sea turtles in Senegal has been improves significantly.
D.The Marine Protected Area has played an important role in protecting fishes.
