203901. （2024•莲湖区•高二上期末）     Plastic is everywhere in our modern world.Its toughness makes it an extremely useful material from household items to vehicle parts，but that same toughness makes it hard to break down for recycling or disposal（处理）.However，Japanese scientists at the University of Tokyo have developed a new plastic material that can be broken down more easily and can self-heal and remember past shapes.
    Based on a kind of plastic called an epoxy resin vitrimer，which is brittle（脆性的），the new plastic boasts a huge range of advantages.Once scratched with a knife，it can completely patch itself up after being heated to 150℃for just 60 seconds.When shaped into the shape of a crane，then flattened，it can fold itself back into the crane shape by being heated up.It does all of this much faster than others of its type.
   The new plastic can also break down easier.Even if it's discarded（丢弃） into the environment，it still poses less of a problem than other kinds of plastic，which the team demonstrated by placing it in seawater for 30 days.It biodegraded by 25% and released molecules（分子） that are essential food for marine life.
   The new plastic is more resistant to breaking.It can also repair itself，and can recover its original memorized shape.It even biodegrades safely in a marine environment，according to Shota Ando，a researcher of the study.
   The material can be used in a variety of applications."Infrastructure materials for roads and bridges are often composed of epoxy resins mixed with compounds such as concrere and carbon，"said Ando."By using the new plastic，these would be easier to maintain as they would be stronger and healable using heat.Unlike conventional epoxy resins，this new material is hard but stretchable，so it could also be expected to strongly bond materials of different hardness and stretch."

（1）What is the author's purpose in writing paragraph 1？
A.To highlight the importance of plastic.

202301. （2022•西工大附中•六模） Reading minds may not be simple，but it might be possible actually.What if a brain scan could reveal your memories？A team of British scientists recently just did that — they used brain scans to look at spatial （空间的） memory in four people.Spatial memory is the kind of memory you use to remember where you are.You use spatial memory to remember how to get from your house to school.People build spatial memory as they explore a new city or a new building and take in information about their surroundings.
   The scientists asked each participant to sit down at a computer and wander through 3 D rooms.These virtual rooms contained images of objects，like clocks and doors，so that the people could know where they were.Each person was encouraged to explore the virtual space.
   As the people became familiar with these rooms，their brains were taking notes of where things were，and how to get from one point to another.After observing these rooms，the participants were instructed to go to a specific location within the rooms.At this point，the scientists took pictures of the people's brains using an instrument called FMRI （核磁共振成像）.As participants stared at the floor，the scientists took FMRI scans to measure brain activity.
   They repeated this process many times.After a few repetitions，the scientists recognized the patterns in the participants' brains.By looking at patterns on the brain scans，the scientists were able to read the spatial memory of the test subjects.
This experiment shows that it is possible to use FMRI to gather some kinds of memories from people.However，your secret thoughts and personal memories are safe — for now. "It is not the case that we can put someone in a brain scanner and simply read his private thoughts，" said one of the scientists who worked on the project.

（1）What can we learn about spatial memory from the first paragraph？
A．It contributes to exploring a new subject.
B．It lets you remember what has been done.
C．It helps you memorize places where you are.
D．It takes in information about new knowledge.
（2）Which of the following is the right order of the study？
a.The scientists took photos of the brains with the FMRI.
b.The scientists read the spatial memory of the participants.
c.The participants were asked to explore virtual rooms.
d.The scientists repeated the process a few times.
A．a，b，c，d
B．c，a，d，b
C．b，c，d，a
D．c，d，a，b
（3）Why are our secret mind and private memories safe？
A．Because FMRIs can't gather any memory from people.
B．Because scientists can't understand all pictures taken by FMRIs.
C．Because FMRIs can't be completely reliable now.
D．Because scientists can't read people's thoughts directly.
（4）What does the passage mainly talk about？
A．Spatial memory and FMRIs.
B．A very important research.
C．How scientists can read people's memories.
D．A new kind of camera — FMRIs.

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．

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

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

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

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.

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.

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.

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.

202559. （2021•长安区•一模） With the help of a robot created by Washington State University（WSU），scientists could help elderly people with dementia and other limitations live independently in their own homes .
   The Robot Activity Support System，or RAS，uses sensors equipped in a WSU smart home to determine where its residents are，what they are doing and when they need assistance with daily activities.It navigates（定位）through rooms and around obstacles to find people on its own，provides video instructions on how to do simple tasks and can even lead its owners to objects like their medication or a snack in the kitchen.
   "RAS combines the convenience of a mobile robot with the activity detection technology of a WSU smart home to provide assistance in the moment，as the need for help is detected." said Bryan Minor，a postdoctoral researcher in the WSU School of Electrical Engineering and Computer Science.
   Currently，about 50 percent adults over the age of 85 need assistance with everyday activities such as preparing meals and taking medication and the annual cost for this assistance in the US is nearly ＄2 trillion.With the number of adults over 85 expected to triple by 2050，researchers hope that technologies like RAS and the WSU smart home will relieve some of the financial pressure on the healthcare system by making it easier for older adults to live alone.
   RAS is the first robot researchers have tried to apply to their smart home environment.They recently published a study in the journal Cognitive Systems Research that shows how RAS could make life easier for older adults struggling to live independently.
   "While we are still in an early stage of development，our initial results with RAS have been promising，" Minor said. "The next step in the research will be to test RAS' performance with a group of older adults to get a better idea of what video reminders and other preferences they have regarding the robot."

（1）Which part is the most important for RAS to serve the elderly？
A．Signal lights.
B．Sensors.
C．Videos.
D．Head size.
（2）What can we learn about RAS？
A．It is the first robot used in daily life.
B．Its function remains to be tested.
C．It can cook for owners on its own.
D．It can locate people and do any task.
（3）What's Minor's attitude toward the future of RAS？
A．Doubtful.
B．Negative.
C．Uncertain.
D．Positive.
（4）What would be a suitable title for the text？
A．Smart Home Tests First Elder Care Robot
B．Elderly People Leave the Nursing Home
C．RAS，the First Robot to Make Home Smart

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
