204622. （2023•高新一中•高二上期末） Dreams，according to Carl Jung，reveal a certain amount of reality hidden during waking consciousness.In Jungian philosophy，the conflict and chaos experienced in dreams finally bring order to our lives.While Jung's mystical theories are debatable，he was not mistaken about the importance of dreaming.A growing number of reportow that a continuous lack of dreaming is damaging our waking hours in many ways.
   This trend is causing damage to our immune and metabolic （新陈代谢的） systems，let alone the electronic products that keep us up late at night are ruining our sleep patterns，which has long-term consequences on our memory system.One study showed that not allowing mice to have adequate amounts of REM （Rapid Eye Movement） sleep，the stage in which we dream，the mice couldn't strengthen memories.
   You might think this is just a sleep problem，but dreaming is inseparable from our nighttime rest.We sleep in cycles，each lasting about 90 minutes；in a sleep cycle，we go through non-REM sleep before hitting REM.As the night progresses，REM sleep periods increase in length while deep sleep （one of the stages of non-REM sleep） decreases.The longer we sleep，the more time we spend in REM，which is why we are often dreaming when waking up in the morning.If we sleep less than seven hours，however，it becomes harder to achieve this level of REM.
   The combination of sleeping and dreaming acts as an emotional stabilizer.We recover from emotional hurt faster when we sleep and dream properly.However，we're not getting enough sleep to cycle through the stages to take advantage of this natural circadian anti-depressant （抗抑郁剂） — dreams.Instead，we get depressed and turn to alcohol or medicines to get to sleep，which only makes things worse because even one drink leads to late REM while anti-depressants promote deep sleep at the expense of REM.
   We're paying for this lack of dreaming in many ways.For example，a 2021 study stated that compared with quiet rest and non-REM sleep，REM promoted the formation of associative networks and the integration （整合） of unassociated information.Volunteers that experienced more REM sleep were better equipped for solving problems requiring creative solutions.
   Rowan Hooper，the managing editor at New Scientist，writes that dreams that include an "emotional core" appear to be a main function of REM sleep and that we should look at sleep patterns as seriously as we do diet and exercise habits.

（1）What's Carl Jung's view about dreams？
A．They cause chaos.
B．They damage immunity.
C．They reveal secrets.
D．They mirror reality.
（2）Why is the sleep process explained in paragraph 3？
A．To show a dream mainly occurs during REM sleep.
B．To prove the minimum sleep time should be seven hours.
C．To prove dream problems and sleep problems are attached.
D．To show people often dream when waking up in the morning.
（3）What conclusion can be inferred from paragraph 5？
A．REM sleep promotes creativity.
B．REM sleep helps fight depression.
C．The brain still receives new information during REM sleep.
D．The brain is paying the price for having more non-REM sleep.
（4）What's the main idea of the passage？
A．The importance of sleep lies in dreams.
B．The absence of dreams is terrible for us.
C．Dreaming patterns are more important than we realize.
D．Dreaming has mystical power of strengthening memories.

203689. （2024•西安中学•高三上期末）     Saving lives has always been an important mission of science.Now science，and indeed all society，are facing a new dilemma：whether or not to try and save more lives through human cloning.
   The first cloning experiments in the 1950s involved frogs and toads.It was not until 1997 that scientists successfully cloned the first mammal，the now world-famoueep known as Dolly.Cloning techniques' have continued to improve since then，and today there are cloned mice，salmon，and cattle.
   Some scientists want to apply the methods used in cloning animals to produce skin，or organs，and other body parts for humans.One of these methods involves taking adult cells from the brain or blood and growing them into new tissues.Another more complex technique takes embryo cells and develops them into a wide variety of cell types and tissues.It is this planned use of human embryos that has resulted in controversy and criticism.
   The cloning of human cells provides the potential to find cures and eliminate diseases.The dream of some researchers is to create a Utopian world of good health.Others question whether it is right to "Play God""in an attempt to cure the disabilities and diseases in this world.
   Some of the great hopes for cloning include the utility to perform transplants，whenever they are needed，using cloned organs.For example，people with lung cancer may simply have their lungs replaced with healthy ones.Scientists also look forward to the day when people in wheelchairs can walk again，and illnesses such as Alzheinmier's and Parkinson's Disease can be prevented.
   However，a lot of people worry about the appearance of masses of identical people，and the production of "perfect"" humans for warfare or slave labor.We might even see headless human bodies being stored at hospitals for their"spare parts".With such thought-causing possibilities for the 2 lst century，human cloning will no doubt continue to receive widespread attention and scrutiny（审视）.

（1）What problem is science faced with？
A.How to carry out human cloning scientifically.
B.Whether human cloning can help save more lives.
C.How to save more lives through human cloning.
D.Whether human cloning should be used for saving lives.
（2）What can we know about cloning according to the text？
A.It has a history of over half a century.
B.It develops very quickly in the 21st century.
C.It can protect people from diseases of any kind.
D.It has enabled many people in wheelchairs to walk again.
（3）The underlined word "eliminate" in paragraph 4 most probably means"        ".
A.put up with
B.get along with
C.make up for
D.get rid of
（4）What can be inferred from the last paragraph？
A.There's a widespread concern over the possible misuse of human cloning.
B.Human cloning may become a trend in the 21st century.
C.The effect of human cloning on society will no longer be a hot topic.
D.Human cloning has more advantages than disadvantages.

203227. （2016•西安一中•一模） The following passage is adapted from the writings of a Nobel Prize-winning scientist．
   Any scientist who is not a pretender will admit the important part that luck plays in scientific discovery．A colleague and I carried out an experiment in which little tissue fragments（组织碎片），which were very difficult to work with，were injected into mice of different DNA strains．If we had been more experienced，we would have injected only white blood cells （which would have been easier to handle） into the mice．We now know that if we had done this，we would not have made the discovery．Obviously，we were lucky，but our scientific training enabled us to recognize the significance of the accident．
   It might nevertheless seem as if luck plays a significant role in scientific discovery．However，I would like to challenge this view for the following reasons：we sometimes describe as "lucky" a person who wins a prize in a lottery at long odds；but if we describe such an event as luck，what word shall we use to describe the accidental discovery of a lottery ticket that turns out to be the winning one just on a park bench？
   The two cases are quite different．A person who buys a lottery ticket is putting himself or herself in the way of winning a prize．This individual has，so to speak，purchased candidacy（候选资格）for such a turn of events and all the rest is a matter of mathematical probabilities．So it is with scientists．A scientist is anyone who，by observations and experiments conducted，by the literature read，and even by the company kept，puts himself or herself in the way of making a discovery．These individuals，by deliberate action，have enormously enlarged their awareness-their candidacy for good fortune-and will now take into account evidence of a kind that a beginner or a casual observer would probably overlook or misinterpret．
   Nearly all successful scientists have emphasized the importance of preparedness of mind，and I want to emphasize that this preparedness of mind is worked for and paid for by a great deal of effort and reflection．If these efforts lead to a discovery，then I think it would be inappropriate to credit such a discovery to luck．

（1）The outcome of the experiment described in paragraph one suggests that
A．luck play an insignificant part in scientific discovery
B．the injection of only while blood cells allowed the two scientists to make their discovery
C．It was difficult to inject little tissue fragments into mice of different DNT strains
D．the scientists concerned in the experiment were able to benefit from luck
（2）The author uses the example of the lottery winner in order to suggest that
A．blind luck occurs more frequently than people realize
B．luck plays a more important part in most events than people realize
C．luck is not the correct term to use when referring to a significant scientific discovery
D．luck is the best word to be used to describe the accidental discovery in science
（3）The author implies that a scientist achieves " candidacy for good fortune" by
A．making careful and repeated mathematical calculations
B．depending on feelings rather than on scientific research
C．performing enough experiments to increase the statistical probability of success
D．obtaining knowledge that allows him or her to recognize important evidence
（4）The primary purpose of the passage is to
A．make a single definition of luck
B．show that scientists discover what they intend to find
C．compare scientific discovery to a lottery game
D．discuss the role of luck in science

202064. （2022•西安中学•三模） Humans are not the only ones that like gold.Australian scientists have discovered a new fungus （真菌） that decorates its long，thread-like tendrils （卷须） with gold collected from the soil.The experts desperately hope the "gold digger" will provide information on the locations of gold deposits and make searching for the precious metal easier，and more environmentally friendly.
   The gold-loving fungus was discovered accidentally by a team of researchers led by Dr.Tsing Bohu，a scientist at Australia national science agency，CSIRO，when they were examining the microbes（微生物） in the soil at Boddington，a tiny town home to Australia's largest gold mine.
   A closer analysis suggested that the fungus uses chemical interactions with underground minerals to accumulate gold from its surroundings.Though fungi often interact with other things in nature，the reaction with gold was unexpected. "Fungi are well-known for playing an important role in the recycling of organic material，such as leaves and bark，as well as for the cycling of other metals，" Dr.Bohu explained. "But gold is so chemically inactive that this interaction is both unusual and surprising."
   The fungi are not wearing the gold for beauty. "There is a biological benefit from this reaction." Dr.Bohu said， "Gold-loving fungi can grow faster and bigger relative to other fungi that don't work with gold."
   The researchers still need to conduct further analysis to understand the relationship between the fungi and the precious metal.More importantly，they need to determine if its presence is a sure sign of the existence of large deposits of the metal underground.The scientists also believe the fungi could be used to detect the presence of gold in waste products and man-made electronics.
   However，those hoping to get free gold from the fungi are in for a disappointment，for the delicate fungus is hard to see.Also，its gold can only be seen under a microscope.

（1）What are the experts starved of？
A．Investigation the sites
B．Excavating the gold mines
C．Getting further informed
D．Unearthing gold deposits
（2）What could be learnt according to Dr.Bohu？
A．Fungi's interaction with gold is unexpected but beneficial.
B．Gold's classification is biologically identified by fungi.
C．Fungi's formation with gold is fairly natural and frequent.
D．Gold is chemically accumulated by fungi's evolution.
（3）How does the author find the finding？
A．It excites the gold diggers' motivation.
B．It has a long way to go before confirmation.
C．It lays the foundation of geological studies.
D．It ensures the search of gold sites.
（4）What can be the suitable title for the text？
A．Beauty-loving Fungi Wrapped by Gold
B．Gold-loving Fungi Discovered in Australia
C．Boddington，Austria's Largest Gold Mine
D．New Discovery of Gold with Fungi

218076. （2023•田家炳中学•高二上二月） The start-up that attracted the largest investment in the history of cybersecurity，of more than half a billion dollars，has a simple goal：a passwordless future.
    Despite the spread of password management software that can generate and remember complicated strings of random characters，some of the most common passwords are still "12345"，"password"and "iloveyou".As a result，more than 80 percent of hacks involve these kinds of passwords；and passwords remain the most sought-after data by hackers，above other personal or sensitive information.
    In many cases，individuals are tricked into handing over password details by phishing emails and other social engineering techniques.Hackers have sought to break into apps and steal entire password databases as well.Passwords are also under attack from new technology，such as automated programs that can rapidly try to guess them，or can try stolen passwords on multiple online accounts.
    Since the need to replace the easily forgotten and highly hackable strings of letters and numbers that we use to access everyday life has become even more urgent，the race to replace the password is under way，with biometric-based（基于生物识别的）security emerging as one of the most sought-after solutions.According to Tico，a union of more than 250 companies，which promotes a standard system of passwordless authentication（身份验证），the vast majority of consumer services will offer passwordless login systems in the next couple of years. "If done correctly and safely，biometrics are really helping us move to a passwordless future in a rapid manner，" said Andrew Jenkinson，CEO of Tieo.
    But there are still risks associated with the use of biometric authentication.Unlike passwords，biometrics cannot be changed.This means such data must be closely guarded for privacy purposes and to prevent spoofing—hackers trying to trick cameras or sensors with photos，or masks of their victim. "Biometric authentication and passwordless authentication has its own attack surface，" said Paul Smith，director of security research at CyberPek.His team revealed that it had found a design problem which would allow potential attackers to bypass facial recognition login by injecting a spoofed photo of a user's face into the process.
    The biggest obstacle standing in the way of the start-ups hoping to kill the password is how to change years of habit.Eric Brown，founder of TAK Cyber，a cyber research and advisory company，argued that while sensitive applications may rapidly shift from passwords，other websites have less motivation to update their systems."You'll never get rid of them，"he said."We're never going to get to the postsword era."

（1）What is the third paragraph mainly about？
A．Why passwords are the most sought-after data.
B．How passwords are stolen by phishing emails.
C．How passwords have caused us trouble.
D．Why passwords are difficult to secure.
（2）What can we infer from the passage？
A．Facial recognition login is the key to fighting hackers.
B．Biometric authentication has its own set of problems.
C．TAK Cyber's login system guarantees the safety of data.
D．Spoofing brings more problems than automated programs.
（3）What is Eric Brown's attitude towards a passwordless future？
A．Indifferent.
B．Passionate.
C．Pessimistic.
D．Objective.
（4）Which would be the best title for the passage？
A．Biometric authentication：password security solution!
B．Start-ups race to welcome a passwordless future
C．The argument to end passwords has begun
D．Killing the password：a cure or a fantasy？

203207. （2016•西安中学•二模） Scientists study the natural world by using"scientific method"．When a scientist observes some phenomenon in nature，he develops an idea，called a theory or hypothesis （假设），about what is happening．Then he does an experiment to test his theory．If the results are as expected，then the experiment proves the hypothesis which makes it more likely that the theory is correct．If the experiment fails and the results are not as expected，then the scientist must come up with a new theory that he can test．
  In ancient times great thinkers came up with complicated theories to explain nature，but they did not always prove them by experiment．For example，the great Greek thinker Aristotle，had a theory that heavy objects would fall faster than light objects．People believed this until the scientist Galileo performed an experiment and found it was wrong．
   Here's an experiment that you can use to prove or disprove a common-sense theory：
   Step 1：Get an empty bottle with a small neck．A diameter （直径） of 1/2 inch should be ideal．
   Step 2：Cut a sheet of paper to a square 5 inches on each si de．
   Step 3：Crumple （压皱） the paper into a tight wad （块状物）．
   Step 4：Lay the bottle on its side and place the paper so it lies loosely in the neck of the bottle．
   Construct a theory about what will happen if you put your mouth about a half inch from the neck of the bottle and blow hard towards it．A common-sense theory might be that the wad would be blown into the bottle by the force of the breath．Now do your experiment to see what really happens．
   If your theory was that the wad would be blown by the force of the air into the bottle，the experiment gave you unexpected results．In most cases the wad is blown out of the neck of the bottle in the opposite direction．A new theory might be that the air being blown into the bottle creates a whirlwind （旋风） of air currents （气流） in the closed space which push the wad out．
（1）The writer mentions Aristotle's theory to show        ．
A．he was a greater thinker in ancient times
B．he was less successful than Galileo
C．objects of different weights fall at the same speed
D．experiments are necessary to support theories
（2）According to the passage，what is not required in the four-step experiment？
A．A pair of scissors．
B．A piece of paper．
C．A bottle．
D．A strong breath．
（3）What's the best title for the passage？
A．Come to Nature with Scientists
B．Make up a New Theory
C．Experiment with Breath in a Bottle
D．Watch Out for Common Sense．

219589. （2020•西安一中•高二上一月） Say goodbye to standing in long lines holding boarding passes and other travel documents.Step this way，instead.Look into the camera lens and off you go.
   Sound convenient？Technology companies working with travel providers and the federal government to install facial recognition systems at airports hope you think so.
   But privacy advocators don't want you to become too comfortable.They worry that what we're willing to accept for convenience today will soften our resistance to the idea of filling public spaces with cameras that can identify us and track our every move.
   Facial recognition technology came suddenly into modern reality with very few people prepared for it.Facial recognition is a biometric technology that uses distinguishable facial features to identify a person.In many cases，we see it being used by governments and law enforcement agencies-testing its accuracy and value for future purposes.
   Today，it's used in a variety of ways from allowing you to unlock your phone，go through security at the airport，purchase products at stores.It checks the identities of ride-hailing drivers，permits tourists to enter attractions and let people pay for things with a smile.Airports are increasingly adding facial recognition technology to security checkpoints（检查站）.It's even said that past footage of unsolved mysteries would benefit greatly from this technology as it would help identify the criminals of crimes long forgotten.
   However，there has been a serious clash between the government and citizens in general over the technology's use cases.At an airport，travelers are requested to present their passports，from which the software will determine whether the person standing in front of the camera matches the identity.If it matches，then they can get through quickly.However，the surveillance（监控）system searches a large database for the face presented to the camera.Editing such a big database，many worry，will inevitably（不可避免地）lead to privacy concerns down the road.The biggest drawback for facial recognition technology in most people's opinions is the threat to an individual's privacy.
   Some say that it's the most powerful tool as they fear for their privacy being invaded almost on a daily basis，while the government tries to push it as something necessary for better civil control and crime prevention.Overall，talks usually boil down to whether facial recognition technology should be banned or if it should be regulated.
   According to IBM，the banning of facial recognition technology would be a step backward for human scientific advancement.However，restricting it within light regulations could yield just as many gains as it would in a "free market".
   There are many useful applications of facial recognition technology-both at the consumer level as a matter of security and convenience，and for governments and law enforcement agencies.The challenge is finding the balance between those benefits and the expectation of privacy.Banning facial recognition is not the answer.Regulating it，however，may be necessary to put an acceptable framework of rules around its use.

（1）With the help of facial recognition，we can        .
A．pass the security at the airport faster
B．figure out unsolved mysteries
C．reduce the number of criminals
D．purchase products at home
（2）Facing the use of this technology，citizens        .
A．have no idea of its benefit
B．have already got well-prepared
C．worry their information is misused
D．refuse to accept the convenience
（3）What does the underlined word "clash" in paragraph 6 probably mean？
A．Conflict.
B．Crisis.
C．Challenge.
D．Consequence.
（4）Which point of view may the author agree to？
A．Banning facial recognition.
B．Regulating facial recognition with rules.
C．Maintaining the current situation.
D．Debating with the government.

204279. （2023•阎良区•高二下期末）     Modem advancements in digital and online technology are changing the art market.Online events are becoming more popular than ever as they can be attended by anyone from anywhere.At the heart of this online art world are OVRs.
   Before going into how OVRs are shaping the art world，it's important to understand what they are.An OVR is an Online Viewing Room that allows art enthusiasts to take part in events through their computer screens.OVRs transmit galleries and events to art lovers through live feed which can be viewed from anywhere in the world!
   OVRs enable art to travel across the world，without ever leaving the studio!This increases the number of possible collectors and buyers that will be able to view new pieces.
   Online viewings also meant that the art market could continue to function and exhibit art，even with lockdown restrictions.Although many events were cancelled，a study showed 41% of wealthy people bought work at a fair in 2020，while 45% did it through an online viewing room.
   Besides，OVR displays can be changed easily and updated at any time.This means that viewers can easily stay on track with the latest works and view updated displays as regularly as they would like.
   While OVRs may be practical，many enthusiasts say that the online viewing platforms don't provide the full gallery experience，and this is their main problem.Physical art shows allow enthusiasts to network with new people，discuss and see the art in real life before making a decision to buy.
   So，will OVRs continue to rise？Probably yes：OVRs are likely to play a big role in future art sales.This is because online viewing platforms bring a number of benefits to art lovers.However，the interactive aspect of viewing art cannot be fully replaced by OVRs，so expect a combination of the physical and the digital art world.

（1）What is the author's main purpose in writing Paragraph 1？
A．To bring up the topic of the text.
B．To list some interesting examples.
C．To show the types of the markets.
D．To introduce a problem to be solved.
（2）What do the percentages in Paragraph 4 show？
A．The art market is easily affected by accidents.
B．OVRs are more effective than face-to-face events.
C．OVRs help the art market to survive during lockdown.
D．People involved in art sales are mostly from wealthy families.
（3）What does Paragraph 6 mainly talk about？
A．The future of OVRs.
B．The history of OVRs.
C．The popularity of OVRs.
D．The disadvantages of OVRs.
（4）What can we know from the last paragraph？
A．OVRs will gradually replace face-to-face art events.
B．OVRs will coexist with the physical art world.
C．OVRs will create an interactive atmosphere for art lovers.
D．OVRs will make up more than half of the future art market.

205528. （2020•蓝田县•高三上期末） Two new movies--Inventing Tomorrow and Science Fair-take audiences behind the posters of the Intel International Science and Engineering Fair （ISEF）.Created by Society for Science & the Public and supported by Intel ISEF brings together thousands of budding （初露头角的） scientists each year.In one week，they compete for prizes and present their science fair projects to the public.
   In Inventing Tomorrow，director Laura Nix follows teens，as they take on environmental problems close to home and bring their solutions to ISEF.Jose Manuel Eliade Esparaza，18，Jesus Alfonso Martinez Aranda，17，and Fernando Miguel Sanchez Villalobos，17，design a paint to absorb the air pollution affecting their home in Monterrey，Mexico.Meanwhile，Sahithi Pingali，16，for example，hates the rubbish poling up in her local lakes in Bangalore，India.She designs a water testing app to help her neighbors monitor water quality. "It is our job as the next generation to solve this." Sahithi said.
   Science Fair doesn't have such a similar scientific message.Instead，it focuses on how the teens present their research at ISEF，and why they want to be there.For example，Robbie Barrat，17，struggles in school in Shenandoah，W.Vs.，but he performs well at home，teaching computers how to sing like Kanye West.Ivo Zell，18，loves to fly model planes in Lorch，Germany，so he invents a new flying wing.The kids in Science Fair seem a bit more realistic than the ideal （理想的） dreamers of Inventing Tomorrow.
   While the movies are both about the same big science fair，neither is really about the science the teens carry out.It's not clear how the students came up with their projects，how they did the science itself or how they found teachers at universities to help them.Instead，the two movies focus on the experience of competing at a huge science fair.It's a place where kids bring their wildest scientific ideas.They find more people like themselves.And it's something that all the teens hope will help them succeed in life.

A．Touching.
B．Inspiring.
C．Humorous.
D．Frightening.
（2）What does Science Fair tell us about？
A．Why the teens take part in the fair.
B．When the teens do the experiments.
C．How the teens solve the air poll.

212667. （2025•临潼区•高二下期中）     Researchers at Columbia University have developed a new artificial intelligence （AI） method that can accurately predict gene activity in any human cell，essentially revealing the cell's inner mechanisms.Detailed in the latest issue of Nature，this system has the potential to change how scientists study cancer，genetic disorders，and other diseases.
    "Predictive generalizable computational models allow to uncover biological processes in a fast and accurate way.These methods can effectively conduct large-scale（大规模的） computational experiments，boosting and guiding traditional experimental approaches，" says Raul Rabadan，senior author of the new paper.
    Traditional biological methodow how cells function or respond to changes，but they lack the ability to predict these processes.Recent advances in AI and massive biological data collections are making thiift possible.However，using AI to predict gene activity inside cells has been a greater challenge—until now.
    Rabadan's team developed an AI model trained on gene expression data from over 1.3 million normal human cells.Unlike earlier models trained on limited data，this system uses genome sequences（基因组序列） and accessibility data to predict which genes are active in any cell.The process is similar to how language models like MindLink，an AI chat tool，work：It learns patterns from data and applies them to new situations.Testing showed the model could accurately predict gene activity in cell types it had not encountered，matching experimental results closely.
    The researchers applied the AI model to study pediatric leukemia，a childhood cancer caused by inherited mutations（遗传变异）.The model predicted how these mutations disturb critical processes in cells，a finding later confirmed through experiments.This understanding highlights the specific mechanisms driving the disease.The AI model could also reveal unexplored regions of the genome，often linked to cancer.These "dark" regions do not code for proteins but may play key roles in disease.
    Already，Rabadan is working with researchers at Columbia and other universities，exploring different cancers，from brain to blood cancers，learning the grammar of regulation in normal cells，and how cells change in the process of cancer development.

（1）What is a problem about traditional biological methods？
A.They are difficult to combine with AI.
B.They can't forecast how cells work.
C.They are expensive in large-scale research.
D.They can't collect biological data effectively.
（2）Why does the author mention MindLink in paragraph 4？
A.To remove public doubts about AI chat tools.
B.To introduce the disadvantages of AI tools.
C.To explain the experimental results from Rabadan's team.
D.To clarify how the AI model developed by Rabadan's team functions.
（3）What does paragraph 5 mainly stress about the new AI model？
A.Its application value.
B.Its popularity.
C.Its complexity.
D.Its design inspiration.
（4）Which can be a suitable title for the text？
A.Scientists Unlock the Secret of Blood Cancers.
B.New AI Model Exposes Secrets of Human Cells.
C.Advances in AI Fuel a Heated Debate in Biology.
D.AI Tools Are Widely Used to Treat Rare Diseases.

212685. （2025•莲湖区•高一下期中）        AI-powered chatbots （聊天机器人） are getting pretty good at identifying some diseases，but how do chatbots do when things are less black and white？For example，how long should a patient stop taking blood thinners before an operation？Should a patient's treatment change if they've had harmful reactions to similar medicine in the past？These kinds of clinical （临床的） crossroads don't have a textbook right or wrong answer — it's up to doctors to use their opinions.
       Researcher Jonathan H.Chen and his team have been exploring whether AI-powered chatbots could effectively answer such questions，and whether doctors supported by chatbots would perform better.
       The team designed a trial to study clinical reasoning performance in three groups：the chatbot alone，46 doctors with chatbots' support，and 46 doctors with access only to Internet search and medical references.They selected five patient cases and gave them to three groups，all of whom were expected to provide a written response that detailed what they would do in each case，and why，and what they considered when making the decision.In addition，the researchers invited a group of authoritative doctors to create scoring standards.The decisions from three groups were then scored according to the standards.
       To the team's surprise，the chatbot outperformed the doctors who had access only to the Internet and medical references，selecting more items on the scoring standards than the doctors did.But the doctors who were paired with chatbots kept up with the chatbot alone.
       What exactly drove the doctor-chatbot cooperation （合作） is up for debate. "Does using chatbots force doctors to be more thoughtful about the case？Or are chatbots providing guidance that the doctors wouldn't have thought of on their own？That needs to be explored，" Chen said. "The positive outcomes for chatbots and doctors paired with chatbots are in AI's favor." Chen added， "This doesn't mean patientould skip （跳过） the doctors and go directly to chatbots.Don't do that."
（1）What did the researchers want to find out through the research？
A．Why patients preferred chatbots over doctors.
B．In which case chatbots could replace doctors.
C．When doctors could outperform AI-powered chatbots.
D．If chatbots could offer reliable advice like doctors do.
（2）How did the researchers conduct their research？
A．By conducting a survey among doctors.
B．By asking authoritative doctors.
C．By having doctors compete with chatbots.
D．By using chatbots to lead doctors.
（3）What do we know from the research？
A．Doctors without chatbots' support performed the best.
B．Chatbots did as well as the doctors with chatbots' support.
C．Chatbots performed worse than doctors with Internet access.
D．Doctors armed with chatbots performed worse than chatbots.
（4）What is Chen's attitude to the use of chatbots in clinical field？
A．Careful.
B．Doubtful.
C．Resistant.
D．Unclear.

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

218284. （2024•西安八十五中•高一下一月） Growing Vegetables in Space Have you ever dreamed of travelling in space？Well，you may not go，but you may be able to eat vegetables grown from seeds that have!China，the USA and Russia have all become interested in whether it is possible to eat food grown from seeds that have been in space.Indeed since 1987 China has sent 1，000 species of seeds into space to do experiments.These include green peppers，tomatoes，cucumbers，carrots，lettuce and wheat.
   The most advanced work on growing vegetables in space has been undertaken on the International Space Station run by Russian and American astronauts.One of the most exciting moments was when soybean seeds were brought back to Earth and planted.These seeds were the first to come from a crop grown entirely in space.
   The scientists chose to grow soybeans in space because they are an important source of protein in the human diet.Mark Nall，director of Space Product Development Programme for National Aeronautics and Space Administration（NASA），said that "this experiment and others are paving the way for improving crops grown on Earth，as well as potentially feeding people living in space." The problem is that producing a new strain of soybean is a slow procedure on Earth so the scientists hope that it can be speeded up in space.
Perhaps the seeds may also develop some characteristics that will be useful for farmers - for example，produce more oil or protein.
   However，the scientists are aware that there may be problems."Conditions in outer space such as radiation and low gravity may cause big changes in the seeds，"said Jin Xing，a Chinese researcher.He knows that genetically modified food is still being debated and so some people will be very suspicious of these"space vegetables".However Jin has a more positive view.He thinks that unlike genetically modified crops，no new genes are being introduced into space vegetables so they will be safe.
   The Chinese government certainly thinks so because they have been cooperating with NASA to produce a new strain of virus-free potatoes.Their scientists hope that in space it may be possible to produce a new crop every 40-50 days instead of one crop a year.So watch out for these special potatoes on the supermarket shelves.Maybe some day you will find them on your dinner table!

（1）The scientists chose to grow soybeans in space because        .
A．scientists know more about soybeans
B．it's easy to begin agricultural experiment from soybeans
C．the soybeanare some common characteristics with other plants
D．the soybeans contain protein needed by the human body
（2）The underlined phrase "pave the way" in the third paragraph means        .
A．to build a new road
B．to make things easier
C．to explore a new area
D．to solve a problem
（3）Mr Jin is positive about space vegetables because        .
A．astronauts have tried eating some space vegetables
B．space vegetables are like genetically modified crops
C．no new genes are being introduced into space vegetables
D．scientists have found that it's safe to eat space vegetables
（4）The writer's opinion about the space potato is that        .
A．the new programme may produce a sound crop
B．people are looking forward to the new product
C．people can buy the new product in the supermarket
D．the new product will have a wide market

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？
A．Where researchers draw inspiration.
B．How the microflier has improved.
C．What the microchip does for humans.
D．Why the microflier flies more stably.
（3）What do the researchers do with the microflier in the future？
A．Drop chips in the field.
B．Monitor the soil color.
C．Map out air pollutants.
D．Handle soil pollution.
（4）Which of the following would be a suitable title for the text？
A．Winged microchips for monitoring environment
B．Microflier：A flying device of spreading seeds
C．Drone：A photographer of microflier's colors
D．Electronic chips for finding airborne diseases
