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.

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.

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

202578. （2021•长安区•二模） Scientists have discovered an astonishing number of Antarctic blue whales in the waters off the coast of South Georgia，an island in the South Atlantic Ocean，suggesting decades of conservation efforts are paying off.
   During a 23-day survey，a team of researchers from the British Antarctic Survey（BAS） counted 55 animals.Dr.Trevor Branch，a scientist from the University of Washington，who specializes in studying blue whales，said the number was truly amazing.
   In the last century，Antarctic blue whales were nearly hunted to extinction for their blubber，a thick layer of fat that marine animals have under their skin to keep their bodies warm.Hunters used the blubber for oil to use in products like soap or fuel for oil lamps.Around South Australia，more than 33，000 whales are believed to have been killed.A hunting ban was introduced in 1966，but by that time the whales were critically endangered.In 2018 there were reported to be only around 3000 Antarctic blue whales left.
   These sightings by the BAS team，helped by scientists from the University of Auckland in New Zealand，are a positive sign that the population is increasing.
   "In a period of 40 or 50 years，I only had records for two sightings of blue whales around South Georgia，" Dr.Branch told the reporter. "So to go from basically nothing to 55 in one year is astonishing." The cold water around South Georgia has always been popular with whales because it is crowded with krill，tiny shrimp-like creatures that are the whales' favorite food.
   The high count was so unusual that other scientists wondered whether it was a one-off，perhaps caused by usually high number of krill temporarily attracting whales from other areas.However，Dr.Jennifer Jackson from BAS says the quantity of krill was no different from other years.She's confident the population growth shown in the recordings is real and down to the protection that the whales now have.This remains to be seen，but it is highly suggested that when the next assessment is released，most likely at the end of 2021，it could show a further increase in the number of Antarctic blue whales.With the comeback of the whale，this could be an inspiration for environmental campaigns that still have progress to make.

（1）Para.3 is mainly about       .
A．the danger that blue whales faced.
B．the efforts to save blue whales.
C．the importance of blue whales.
D．the effect of the hunting ban.
（2）What can we infer about the blue whales from the passage？
A．They will not be endangered in the near future.
B．The number of them rises because their food increases.
C．More conservation activities will be held to protect them.
D．The coast of South Georgia offered them suitable temperature.
（3）As for other scientists' opinion on the high count，Dr.Jennifer Jackson is       .
A．supportive
B．disapproving
C．fearful
D．uncertain
（4）What is the best title of the passage？
A．Blue Whales Makes Surprise Comeback
B．An Amazing Secret of Blue Whales
C．The Best Way to Protect Blue Whales
D．Blue Whales Set New Trends in Conservation

203380. （2016•西工大附中•四模） A recent study，while showing a generally positive attitude toward science，also suggests a widespread worry that it may be "running out of control"．This idea is dangerous．
   Science can be a force for evil as well as for good．Its applications can be channeled either way，depending on our decisions．The decisions we make，personally or collectively，will determine the outcomes of science．But here is a real danger．Science is advancing so fast and is so strongly influenced by businesses that we are likely to believe whatever decisions we come to will make little difference．And，rather than fighting for the best possible policies，we may step back and do nothing．
   Some people go even further．They say that despite the moral and legal objections（反对），whatever is scientifically possible will be done-somewhere，sometime．They believe that science will get out of control in the end．This belief is dangerous too，because it fuels a sense of hopelessness and discourages them from making efforts to build a safer world．
   In our interconnected world，the lack of agreement in and out of the world of science can lead to the failure to control the use of science．Without a common understanding，the challenges of "controlling" science in this century will be really tough．Take human cloning for example．Despite the general agreement among scientists on its possible huge impact（影响） on traditional moral values，some countries still go ahead with the research and development of its related techniques．The outcomes are hard to predict．
   Therefore，discussions on how science is applied should be extended far beyond scientific societies．Only through the united efforts of people with hope，can we be fully safe against the misuse of science and can science best serve mankind in the future．

（1）What can we conclude from the recent study？
A．People think highly of science．
B．Science is getting dangerously out of control．
C．People hold mixed opinions about science．
D．Science is used for both good and bad purposes．
（2）According to the passage，what will happen if we hold that science is getting beyond control？
A．The development of science will hopelessly slow down．
B．The public will lose faith in bringing about a bright future．
C．Businesses will have even greater influence on science．
D．People will work more actively to put science under control．
（3）The discussion should reach beyond scientific societies because
A．scientists have failed to predict the outcomes
B．the ties between different areas need strengthening
C．united efforts are necessary for the development of science
D．people need to work together to prevent the bad use of science
（4）What is the main idea of the passage？
A．Science and its applications bring us many dangers．
B．Mankind can largely take control of science with their efforts．
C．The future of science will be influenced by the dangerous ideas．
D．The development of science mostly lies in people's attitudes．

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.

（1）Which word can best describe Inventing Tomorrow？
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.
D．How the teens come up with their projects.
（3）What's the purpose of the two movies？
A．To popularize science.
B．To make the teens famous.
C．To advertise the science fair.
D．To encourage scientific spirit.
（4）What would be the best title for the text？
A．Teenagers' contributions to science.
B．Teenagers' efforts to take on science projects.
C．New movies give an inside look at science fairs.
D．Young scientists find ways to solve many problems.

204012. （2023•师大附中•高二下期末） If you have gone to the cinema and watched the popular movie "The Wandering Earth II" recently，you might be impressed by the intelligent computer MOSS.It can make the reasonable decision in the shortest time based on the given conditions.In fact，such strong AI like MOSS does not exist in reality for the time being.
   However，weaker AI，which replaces human processing in a specific field，has already influenced our daily life.For example，OpenAI，the San Francisco-based startup opened up the language model ChatGPT for public testing in November 2022.Compared with traditional search engines，which display simple results according to searching keywords，ChatGPT can interact with people just like dialoguing，answer professional questions，and also answer follow-up questions.Thanks to its revolutionary user experience，ChatGPT obtained more than one million users just five days after its release.
   More than a Chatbot，ChatGPT can also realize article creation，code generating and other functions only by requesting.ChatGPT can even write code such as Python，debug （排错）code and generate comments for code just like a professional programmer.It also presented strong capacity in content continuation，literary creation，music creation，etc.It is so powerful that New York City public schools have banned it from their networks and school devices.
   However，ChatGPT is still far from perfect.Even OpenAI's CEO once said， "It's a mistake to be relying on it for anything important right now.It's a preview of progress.We have lots of work to do on robustness（稳健性）and truthfulness."
   Even though AI like ChatGPT still has a long way to go，predictions about how the technology will influence our society are already there.Among the industries that may be most affected by ChatGPT，experts say，are journalism，law and translation.

（1）Why is the movie "The Wandering Earth II" mentioned in the first paragraph？
A．To introduce the topic of the text.
B．To prove that the movie is a hit.

D．To advertise the movie.
（2）Which statement about ChatGPT will the author probably agree with？
A．It's well-received for its truthfulness.
B．It can just display simple results content.
C．It should be banned from all school networks.
D．It makes human-machine interaction more intelligent.
（3）What does the OpenAI's CEO think of ChatGPT？
A．It's totally reliable.
B．It needs improving.
C．It's of no use.
D．It should speed up its progress.
（4）What is the best title for the text？
A．ChatGPT Works
B．ChatGPT Sells Well

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

202890. （2018•西安中学•二模） Scientific experiments can sometimes go wrong and when they do，the results may range from the disastrous to the troubling．One such experiment took place in South America about fifty years ago．Whether its final consequences will cause serious damage or nothing more than a small trouble still remains to be seen．
   The story began in 1956 when an American scientist working in Brazil decided to solve the problem of increasing the productivity of that country's bees．He imported a very active type of African bee from Tanzania and mated （交配） it with the more easy-going native variety to produce a new kind of bees．The new bees worked harder and produced twice as much honey．It seemed that Professor Kerr，for that was the scientist's name，had a total success on his hands．
   Then things began to go wrong．For some reason as yet unseen，but perhaps as a result of something in their environment，the new bees began to develop extremely attacking personalities．They became bad-tempered and easy to be angry，attacked the native bees and drove them from their living places．
   But worse was to follow．Having taken over the countryside，the new bees，with their dangerous stings （叮），began to attack its neighbors - cats，dogs，horses，chickens and finally man himself．A long period of terror began that has so far killed a great number of animals and about 150 human beings．
   This would have been bad enough if the bees had stayed in Brazil．But now they are on the move，heading northwards in countless millions towards Central and North America，and moving at the alarming speed of 200 miles a year．The countries that lie in their path are naturally worried because it looks as if nothing can be done to stop them．

（1）The results of the South American experiment        ．
A．have caused a serious trouble

（3）Which of the following may be the cause of the new bees' attacking personalities？
A．Their production of honey．
B．Their hard work．
C．Their living environment．
D．Their bad temper．
（4）The last paragraph implies that        ．
A．the bees have been driven to Central and North America
B．the bees may bring about trouble in more countries
C．the bees must be stopped from moving north

    Developed by Quantum Think Labs in Shenzhen，DeepSeek was created by a team of ex-Google Brain engineers and Peking University experts.DeepSeek is not your average chatbot.Trained on an astonishing 20 trillion tokens，this multimodal model showcases linguistic proficiency，code generation capabilities and reasoning skills that rival or surpass its Western counterparts.What truly sets DeepSeek apart is its remarkable efficiency，delivering GPT-4-level performance with 30 percent less computational power.
    In a strategic move，Quantum Think made a"lite"version of DeepSeek open source，a decision that has sparked widespread adoption across the globe.Developers from cities like Lagos to Jakarta have quickly embraced it to create poetry generators and AI-powered farm management tools for rural India.
    However，DeepSeek's growing influence is not without challenges.There are concerns that US government may block American firms from using DeepSeek，mentioning data security concerns.Tariff（关税） war could also be on the cards.Yet，such moves might backfire，potentially harming US startups that benefit from DeepSeek's cost advantages.
    The future of AI，with DeepSeek at the center，remains a mystery.Will it trigger a tech battle between the US and China，or will its open-source roots foster global collaboration？DeepSeek's story is not just about technology；it's about the power of innovation and agency.
    For too long，the AI narrative has been dominated by Western powers.Now，a Chinese lab haown that innovation is not exclusive to the West.Whether we enter an AI arms race or begin a new era of global cooperation depends on how we choose to use and share this technology.As a Brazilian coder said，the future of AI must speak the language of both the developed and developing world to truly succeed.

（1）What does the second paragraph mainly talk about？
A.The creation of DeepSeek.
B.The definition of DeepSeek.
C.The strengths of DeepSeek.
D.The efficiency of DeepSeek.
（2）What might be a challenge DeepSeek faces？

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

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．

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

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
