[解析]

（1）词义猜测题。根据第一段前两句话Facial recognition cameras are everywhere，including in your smartphone.Many people rely on this technology to unlock their phones，open doors or make quick payments，but there is a problem：Everyone is wearing mask.（面部识别摄像头无处不在，包括智能手机。许多人依靠这项技术解锁手机、开门或快速付款，但有一个问题：每个人都戴着口罩。）可知，由于现在人人都带着口罩，所以人脸识别相对来说"更麻烦了"，所以划线单词hassle的意思，是"问题"。A.Rule规则；B.Habit习惯；C.Mistake错误；D.Problem问题。故选D。
（2）细节理解题。根据第三段Beijing﹣based tech company Hanwang has announced a software which can correctly recognize 95 percent of people wearing masks，Engineering & Technology （E&T） reported.What's the secret？It's all about your eyes.（据工程与技术（E&T）报道，总部位于北京的科技公司汉旺（Hanwang）发布了一款软件，该软件可以正确识别95%戴面具的人。秘密是什么？都是因为你的眼睛。）可知，是眼睛让在戴面具时也可识别面部。故选A。
（3）推理判断题。根据最后一段黄磊说的话It can detect crime suspects，" said Huang Lei，Hanwang's president.Hanwang's technology is used by police in high﹣security settings.This means places like government buildings，subway stations and airports.Huang admits one big weakness of this new technology：It fails when people wear both masks and sunglasses. "In this situation，all of the key facial information is lost，but I believe we can overcome the weakness in the future，" said Huang（"它可以发现犯罪嫌疑人，"汉旺总裁黄磊表示。汉旺的技术被警方用于高度安全的环境中。这意味着像政府大楼、地铁站和机场这样的地方。黄承认这项新技术的一大弱点：当人们同时戴口罩和太阳镜时，这项技术就失败了。黄说："在这种情况下，所有关键的面部信息都会丢失，但我相信我们可以在未来克服这个弱点。"）可知，黄磊对这项技术是非常赞成支持的，所以可推知他对这项技术持积极的态度。故选B。
（4）推理判断题。根据最后一段黄磊说的话Huang admits one big weakness of this new technology：It fails when people wear both masks and sunglasses. "In this situation，all of the key facial information is lost，but I believe we can overcome the weakness in the future，" said Huang.（黄承认这项新技术的一大弱点：当人们同时戴口罩和太阳镜时，这项技术就失败了。黄说："在这种情况下，所有关键的面部信息都会丢失，但我相信我们可以在未来克服这个弱点。"）可推知，这项技术还需改善。故选A。

282042. （2024•西安中学•高二上期中）     Using AI，a group of researchers from Dalhousie University have begun the surprisingly complicated work of translating the language of chickens.This groundbreaking study about chicken vocalizations（发声） could have positive effects on chicken welfare.
     Chicken"speech" is actually a lot more complex than one might think-they squawk，cluck，and even purr.And the way they communicate with one another can be affected by their environment，age，and level of domestication（驯化）.In addition，according to The Debrief，chickens also communicate via visual cues such as body language and facial expressions.
     Luckily，the researchers were able to use new AI technologies to help interpret what chickens are saying.According to The Conversation，AI can process and analyze huge amounts of audio（音频的） data.It can recognize patterns and types of vocalizations.Using this information and an AI technique called Natural Language Processing，the researchers have begun to interpret the emotional states of chickens.
     In addition，the researchers also used data from video and thermal imaging（热成像），tracking the chickens' expressions and facial temperatures.This can be used to track how chickens respond to stressors.
     Neethirajan，an expert in stock farming（畜牧业），and the lead researcher of the study，told The Conversation that his team's interest in chicken communication is not just academic.The researchers hope that this could be a turning point in terms of stock farming.
     "Farmers can use this knowledge to create better living conditions，leading to healthier and happier chickens.This，in turn，can impact the quality of produce，animal health and overall farm efficiency，" he said.Additionally，he advocates for the use of this information to influence animal welfare policies.The more people understand animals，the more likely they are to care about their well-being.

28. The underlined word"welfare" is closest in meaning to         .
A.social security
B.happiness
C.communication
D.domestication
29. What can we know about chicken"speech"？

213315. （2022•师大附中•高一上期中） In the American Journal of Physics，three high school students from Portugal，along with their teacher，have reported the results of their project.The students programmed an add-on （附加装置）board for the Raspberry Pi computer to map out Earth's magnetic field （磁场）.
   The European Space Agency teamed up with the U.K.'s Raspberry Pi Foundation to hold a competition for high school students.The competition，known as the Astro Pi Challenge，required the students to program a Raspberry Pi computer to be run aboard the International Space Station （ISS）.
   The students used the data （数据） from the space station to map out Earth's magnetic field and compared their results to data provided by the International Geomagnetic Reference Field （IGRF国际地磁参考场）. "
   "I saw the Astro Pi Challenge as a way to increase my knowledge and skill set，and it ended up introducing me to the exciting reality of the practical world，" Louren?o Faria，co-author and one of the students of the project，said.
   The IGRF data is updated （更新） every five years，so the students compared their results，taken in April 2021，with the latest IGRF data from 2020.They found their data differed from the IGRF results.This difference could be because of the magnetic field inside the space station.
   The students repeated their tests using another set of data from ISS and found a good improvement in results.The students thought it astonishing that the main features （特征） of Earth's magnetic field could be remeasured （再次测量） with only three hours' worth of computing from their low-cost add-on board in the space station.
   Although this project was carried out aboard the space station，it could easily be applied to ground-based measurements using apps for smartphones.

213810. （2023•西安八十三中•高一下期中） Hunger is a very real problem around the globe.This year，almost 7 million people have died of hunger already.Why do people still die of hunger when there's more than enough food in the world？
   Well，considering that there are places in the world where basic needs like housing and clean，drinkable water are not met，then it doesn't come as a surprise that food is just not accessible to them.The food exists—it just doesn't get to where it needs to be.
   Nigerian farmer Samson Ogbole decided to go ahead and cultivate（培育） fruit and vegetables in a different way.Ogbole's farming process centres around two concepts：soilless farm-ing and aeroponics（气雾栽培）.To put it simply—he's growing food in the air.
   As Ogbole explained during a TED talk，aeroponics is the future of agriculture because it offers many benefits.For example，it is cheaper than traditional farming because there is no need to hire as many workers since everything is done with a"click".Also，this kind of farm-ing is more environmentally friendly since farmers don't use pesticides.At the same time，there are no space limitations—planting in the air means you can plant as many layers as you like.The sky is the limit literally!
   So，the young farmer has been practicing aeroponics for more than five years with impressive results.His work was recently praised on social media this summer when he was featured in a network post.In the post，Ogbole's farming method was mentioned，and Internet users had the chance to see pictures of the farmer's produce.
   Many viewers think southern Nigeria needs this method to grow crops.This will help in bringing down the price and avoiding future food blockades from the north.It seems that people are already realizing that this method will change the way people grow food.And，most importantly，it will help solve some of the issues related to hunger around the world.

（1）What does the figure in paragraph 1 show？
A．The necessity of growing food in the air.
B．The number of hungry people.
C．The seriousness of hunger.
D．The existing population problem.
（2）Why do people still starve to death in the world according to the text？
A．Food is not equally shared.
B．Their basic needs are not met.
C．There is not enough food supply.
D．They have no scientific planting methods.
（3）What is paragraph 4 mainly about？
A．The theory of aeroponics.
B．The advantages of aeroponics.
C．How to grow food in the air.
D．The downsides of traditional farming.
（4）What do viewers think of Ogbole's farming method？
A．Unrealistic.

213763. （2023•西安三中•高二下期中） There are plenty of concerns about robots stealing jobs from hard-working，flesh-and-blood humans.However，Japan's Henna "Strange" Hotel has fired half of its 243 robot staff，because these labor-saving machines were causing more problems than they were solving— and requiring humans to come in and fix things as a result.
One of the victims of the robot layoffs was a doll-shaped robot called Cheri，which functioned as an artificial intelligence assistant.Unfortunately.Cheri tuned out to be pretty poor at answering questions from hotel guests.A pair of dinosaur robots，which worked at the hotel check-in，were also made non-existent by the firings since they wound up being unable to do many of the jobs required of 8 receptionist.A concierge （服务台职员） robot，meanwhile，was replaced by a human better able to answer important questions about nearby tourist attractions.Humans are also now going to carry luggage to the rooms，one quarter of which the previous porter robots were only able to reach—and only in excellent weather conditions.
Not surprisingly，the hotel，recognized in 2016 as the world's first robot-staffed hotel by Guinness World Records， allured curious visitors from all around the world.Encouraged by the success the hotel s owner，Sawada opened seven additional locations across Japan and announced plans to build at least 50 more.
In the end，though，it seems that—as great as robots can be—they're simply not suitable for every role just yet.With the rise of robot bar-tenders，robot-staffed restaurants and the like，it will be interesting to see how many similar concepts fall apart in the coming years.After all，once the novelty of a dinosaur robot on reception wears off，you're just faced with a receptionist who can't properly understand you and lacks an effective number of fingers on each hand to properly photocopy your passport.

（1）Which of the following was used to answer such questions as scenic spots？
A．A porter robot.
B．A dinosaur robot.
C．A concierge robot.
D．A doll-shaped robot.
（2）What does the underlined word "allured" refer to in Paragraph 3？
A．attracted
B．relaxed
C．thrilled
D．upset
（3）What does the author think of the robot staff？
A．They did better than humans.
B．They couldn't replace humans entirely.
C．The rest of them will be fired.
D．They were a big challenge for humans.
（4）What might be the most suitable title of the text？
A．World's First Robot-staffed Hotel.
B．Robots Perform Various Functions.
C．Humans Will Replace Robots Eventually.
D．Japanese Hotel Fires Half Its Robot Staff.

213745. （2023•高陵一中•高二下期中）     There's a new AI bot：ChatGPT，and you'd better pay attention，even if you aren't into artificial intelligence.The tool is an AI chatbot system that OpenAI released in November 2022 to show off and test what a very large，powerful AI system can achieve.
   ChatGPT remembers the thread of your dialogue，using previous questions and answers to inform its next responses.It derives（获得） its answers from huge volumes of information on the Internet.ChatGPT is built on top of the OpenAI GPT-3 family of large language models and is fine-tuned （a method of transfer learning） using both supervised and reinforcement learning （监督和强化学习）.
   You can ask ChatGPT anything，like explaining physics，asking for birthday party ideas and getting programming help.Perhaps it's not smart enough to replace all humans yet，but it can be creative，and its answers can sound downright authoritative（权威的）.A few days after its launch，more than 1 million people were trying out ChatGPT.UBS analyst Loyd Walmsley estimated in February 2023 that ChatGPT reached 100 million monthly users in January，accomplishing in 2 months what took TikTok about 9 months and Instagram two and a half years.
   ChatGPT is free to use at the moment because it is still in its research period.But when too many people hop onto the server（跳转到服务器），it overloads and cannot process your request.It just means you should try visiting the site at a later time when fewer people are trying to access it.If you want to skip the wait and have reliable access，there is a choice for you，ChatGPT Plus，which allows users to have general access even during peak times.This service does come at a cost of ﹩20 per month.
    However，ChatGPT cannot replace Google.ChatGPT is an artificial intelligence robot that provides solutions to your questions，but Google is a search engine in which you can search for as much information as possible.ChatGPT has limited knowledge due to its programming but Google has unlimited knowledge which is updated every day.

（1）What does paragraph 2 mainly tell us about ChatGPT？
A．Its working theory.
B．Its language model.
C．Its design inspiration.
D．Its development process.
（2）Why does the author list figures in paragraph 3？
A．To show the popularity of ChatGPT.
B．To stress the high cost of inventing ChatGPT.
C．To present the creativity of artificial intelligence.
D．To prove the necessity of developing tools for chatting online.
（3）What is ChatGPT Plus intended for？
A．Guiding users to experience free services.
B．Giving users priority access during peak hours.
C．Allowing net surfers to skip advertisements.
D．Helping researchers detect the failure of the system.
（4）What is a limitation of ChatGPT compared with Google？
A．It may provide replies unrelated to the questions.
B．It can only update information at a fixed time
C．It needs longer to provide solutions.
D．It operates based on limited data.

213715. （2022•高新一中•高二上期中） There's a continuing controversy over whether electric vehicleould produce sounds to let the blind and other pedestrians know they're on the scene.Some think those soundould be standardized—like the"beep，beep"of heavy machinery backing up，so you'll think "something heavy is coming this way"when you hear it—— and some think any sound will do.
   This is a serious subject.Plug-in hybrid cars（电混动力车） and battery electric vehicles are super-quiet，and a study at the University of California，Riverside concludes that people listening to recordings on headphones can hear a regular gas car coming from 28 feet away，but a hybrid in battery mode only when it's 7 feet away.
   In response，the European Union has put new rules into play：all new electric vehicle models must have a sound-producing device，which sounds like a traditional engine.Starting in 2021，all new electric vehicles of any model will need the Acoustic Vehicle Alerting System or AVAS.That sound will come into play when the car is traveling backwards or when it's traveling at less than 12 miles an hour—speeds at which cars are more likely to be mixing with pedestrians.
   That's a nice start，say representatives for the blind，but more is needed."We're calling on the government to take this announcement further by requiring AVAS on all existing electric and hybrid vehicles and ensuring drivers have them switched on，" John Welsman，a guide dog owner and Guide Dogs staff member，said in a statement.
   Drivers in most cases have the ability to shut off the device when needed.My guess is that they will eventually be standardized so your mind will automatically register"electric car" when you hear it.And that's probably a good thing to reduce the mayhem（混乱） on the roads.

（1）How does the author show"electric cars are quiet"in Paragraph 2？
A．By making a classification.
B．By making a comparison.；
C．By analyzing cause and effect.
D．By setting down general rules.
（2）What can be learned about the AVAS？
A．It was developed by the European Union.
B．It was designed for inexperienced drivers.
C．It consists of a sound-producing device and an engine.
D．It warns pedestrians of the coming of an electric car.
（3）What does John Welsman think of the new rules？
A．They are too strict for drivers.
B．They are too complex to follow.
C．They need further improvement.
D．They hardly allow for any flexibility.
（4）Which of the following can be the best title of the passage？
A．Electric cars with a standardized sound-producing device.
B．The increasing popularity of a new type of electric car on sale.
C．The current problems with electric vehicles.
D．Quiet electric cars' disorganization on roads.

213495. （2022•长安区一中•高一上期中） Alibaba Cloud and the Hangzhou city government announced the launch of ET City Brain 2.0，a cloud-powered and AI-driven urban traffic-management system that aims to increase the city's efficiency.
   After over two years of testing in Alibaba's home base，ET City Brain has become the new infrastructure （基础设施） for Hangzhou，with a total coverage of 420 square kilometers in area，including over 1，300 traffic lights.Over 200 traffic officers are connected via mobile phones，enabling them to receive real-time alerts on any traffic-related emergencies.
   In version 2.0，the system will optimize the city's firefighting abilities by providing key information to firefighters，such as water pressure，the number and position of fire hydrants （消防栓） in a given area，the location of gas pipes and other details they need to know.The information is instant，making the entire firefighting process faster，safer and more accurate.
   City Brain gives meaning to data.By using AI and advanced algorithms （计算程序），City Brain is able to analyze a large amount of data and turn them into useful information in real-time speed.
   As a result of City Brain's ability to predict traffic flow，detect accidents and provide instant feedback，Hangzhou has dropped from 5th to the 57th on the list of China's most congested cities.Hangzhou is probably the only city that can tell you how many cars are on the street at any given time.
   In the case of medical emergencies，City Brain is able to change traffic lights，so emergency vehicles like ambulances and fire trucks can head to the scene without interruption，accelerating their arrival time by 49%.
   Dr.Wang Jian，head of Alibaba's Technology Steering Committee who invented the term "City Brain"，said the system is designed to empower a city to act quickly and directly.It is more than just about traffic management.It's really about how to make city more livable at a time of shrinking natural resources around the globe. "It is a matter of sustainability，while using as little natural resources as possible，" Wang said， "This is just the beginning."

213458. （2023•周至六中•高二下期中） The UK's largest and most advanced robotics centre，the National Robotarium，opened on Sep.28th，2022 in Edinburgh，is aimed to be a world-leading centre for robotics and artificial intelligence.It's hosted by Heriot-Watt University and the University of Edinburgh and received ￡21 million in funding from the UK government as well as ￡1.4 million from the Scottish government.
   Stewart Miller，the chief executive of the National Robotarium has said that society needs to prepare for the increased integration of robots but shouldn't fear the rise of artificial intelligence （AI）.He told Sky-News that "Necessarily there will be more robots in everybody's life.They'll be helping you at home，when you go out shopping，when you go to a hotel，they'll serve you，when you go to a theatre，everything.And in your working life."
   Internationally，some scientists have expressed concerns over rapid progress in the field of artificial intelligence.A new survey of researchers from the New York University Centre for Data Science found that more than a third （36%） of respondents that had published recent papers in the field thought that AI could produce catastrophic outcomes in this century， "on the level of all-out nuclear war".
   Mr.Miller said， "The thing to remember is that we，the humans，are in control.We decide how far it goes and doesn't go".He added， "A lot of people have already been working on making sure the software sitting behind AI has safeguards built into it." To make sure that，particularly when it's running on a robotic platform，it can't do any harm or at least we make sure it does as minimal harm as we possibly can.So those kinds of safeguards will be built in by the engineers. "We will have to put safeguards in place and make sure we have good controls around it，because artificial intelligence is a very powerful technology.But I think it has more things to bring that will be good than we have to worry about."

（1）What can we learn about AI from paragraph 2？
A．It brings fear to the whole society.
B．It takes place of human labour.
C．It helps human in many ways.
D．It's generally applied to service industry.
（2）What does the underlined word "catastrophic" mean in paragraph 3？
A．Disastrous.
B．Dramatic.
C．Surprising.
D．Promising.
（3）What measures have been taken to avoid the threat from AI？
A．Hiring safeguards.
B．Setting up a security website.
C．Purchasing security systems.
D．Putting security software in place.
（4）What's the text mainly about？
A．Security defense of artificial intelligence.
B．No need to worry about artificial intelligence.
C．Wide application of artificial intelligence.
D．Major problems brought by artificial intelligence.

214805. （2017•长安区一中•高二上期中） Modern inventions have speeded up people's lives amazingly．Motor-cars cover a hundred miles in little more than an hour．Aircraft cross the world a day，while computers operate at lightning speed．Indeed，this love of speed seems never-ending．
All this saves time，but at a price．When we lose or gain half a day in speeding across the world in an airplane，our bodies tell us so．We get the uncomfortable feeling known as jet-lag．Again，spending too long at computers results in painful wrists and fingers．Mobile phones also have their dangers according to some scientists；too much use may transmit harmful radiation into our brains，a consequence we do not like to think about．
However，what do we do with the time we have saved？Certainly not relax．We are so accustomed to constant activity that we find it difficult to sit and do nothing．Perhaps the days are long gone when we might listen quietly to a story on the radio，letting imagination take us into another world．
There was a time when some people's lives were devoted simply to the cultivation of the land or the care of cattle．No multi-tasking there；their lives went on at a much gentler pace．There is much that we might envy about a way of life like this．Yet before we do so，we must think of the hard tasks our ancestors faced：they farmed with bare hands，often lived close to hunger，and had to fashion tools from wood and stone．Modern machinery has freed people from that primitive（原始的） existence．

（1）The new products become more and more time-saving because        ．
A．our love of speed seems never-ending
B．time is limited
C．the prices are increasingly high
D．the manufacturers boast a lot
（2）What does"the days"in Paragraph 3 refer to        ？

213050. （2023•铁一中学•高二上期中）     What if your smartphone or laptop starts charging as soon as you walk in the door？Scientists have developed a specially-built room that can conduct energy to a variety of electronic devices within it without plugs or batteries.
    It's a custom test room of about 18 m³，built from conductive aluminum panels （铝板） with a metal pole running down the middle.When the scientists ran an electric current through the walls and pole following a set pattern，it produced two separate magnetic （磁的） fields：one that fills the center of the room and the other that covers the corners，thus allowing any devices within the space to charge.
    By carrying out tests，scientists found their method could deliver 50 watts of power throughout the room，firing up all devices they tested.Without safeguards，running currents through the room's metal walls would typically fill it with two types of waves：electric and magnetic.This presents a problem，because electric fields can produce heat in biological tissues and pose a danger to humans.So the team built capacitors，devices that store electric energy，in the walls. "It limits the safe magnetic fields to the room volume （室容积） while limiting risky parts to all the components built in the walls." lead author Takuya Sasatani explains.
    The scientists also tested the room's safety，and the result showed the absorption of energy would remain well below acceptable limits. "We're not saying this technology is safe under all circumstances — we're still exploring，" says study co-author Alanson Sample. "But it shows us that there's still much area to explore."
    But applying the technology is still far in the future. "It's just too troublesome to put aluminum sheets all over the wall — that benefit doesn't make sense yet，" Sample says. "We've just developed a brand-new technique.Now we have to figure out how to make it practical." He plans to continue researching whether coating existing rooms with conductive material could enable the construction of wireless-charging rooms in line with building standards.Meanwhile，scientists hope to improve the efficiency of power conduction in the room and remove spots that the charge does not reach.

（1）What does paragraph 2 mainly talk about？
A．What the room looks like.
B．How electric currents are generated.
C．How the special room works.
D．What the technology was developed for.
（2）What are the capacitors used to do？
A．Produce electric power.
B．Measure magnetic field.
C．Prevent devices from heating.
D．Shelter people from harm.
（3）What is Alanson Sample's attitude to the technology？
A．Unconcerned.
B．Cautious.
C．Doubtful.
D．Content.
（4）What's the major barrier to the technology's application？

212964. （2023•铁一中学•高二上期中） Can a small group of drones（无人机）guarantee the safety and reliability of railways and，at the same time，help railway operators save billions of euros each year？That is the very likely future of applying today's "eyes in the sky" technology to making sure that the millions of kilometres of rail tracks and infrastructure（基础设施）worldwide are safe for trains on a 24/7 basis.
   Drones are already being used to examine high-tension electrical lines.They could do precisely the same thing to inspect railway lines and other vital aspects of rail infrastructure such as the correct position of railway tracks and switching points.The more regularly they can be inspected，the more railway safety，reliability and on-time performance will be improved.Costs would be cut and operations would be more efficient（高效）across the board.
   That includes huge savings in maintenance costs and better protection of railway personnel safety.It is calculated that European railways alone spend approximately 20 billion euros a year on maintenance，including sending maintenance staff，often at night，to inspect and repair the rail infrastructure.That can be dangerous work that could be avoided with drones assisting the crews' efforts.
   By using the latest technologies，drones could also start providing higher-value services for railways，detecting faults in the rail or switches，before they can cause any safety problems.To perform these tasks，drones for rail don't need to be flying overhead.Engineers are now working on a new concept：the rail drones of the future.They will be moving on the track ahead of the train，and programmed to run autonomously.Very small drones with advanced sensors and AI and travelling ahead of the train could guide it like a co-pilot.With their ability to see ahead，they could signal any problem，so that fast-moving trains would be able to react in time.

（1）What makes the application of drones to rail lines possible？
A．Drones' ability to work at high altitudes.
B．The use of drones in checking on power lines.
C．The reduction of cost in designing drones.
D．Drones' reliable performance in remote areas.
（2）What does "maintenance" underlined in paragraph 3 refer to？
A．Inspection and repair.
B．Personnel safety.
C．Assistance from drones.
D．Construction of infrastructure.
（3）What function is expected of the rail drones？
A．To provide early warning.
B．To earn profits for the crews.
C．To make trains run automatically.
D．To accelerate transportation.
（4）Which is the most suitable title for the text？
A．What Faults Can Be Detected with Drones
B．How Production of Drones Can Be Expanded
C．What Difficulty Drone Development Will Face
D．How Drones Will Change the Future of Railways

212830. （2024•师大附中•高一下期中） Virtual reality is quickly becoming the new technological frontier.Tech companies everywhere seem to be racing to get their foot in the VR door.However，Virtual reality has a set of challenges and hurdles that it must overcome in order to work well.It should be noted that VR is heavily dependent on being very fast，very accurate and very good-looking.If it isn't，the viewer will feel motion sick or disconnected from the world that VR is trying to create.
   Now that we can actually build VR headsets that begin to meet these requirements，we are seeing a rising interest in VR.As it rises，so does the interest in creating new media to be experienced in using virtual reality.Journalism is a medium built on relevance.Journalistould always be finding new ways to tell stories and deliver content.It is a goldmine for storytelling.What better ways to tell a story to someone than to put them right in the center of it？
   Virtual reality is a powerful tool for journalists.The consumer isn't just reading or watching something play out；they're experiencing it.The immersive nature of VR allows for people to connect with the subject matter on a much deeper level than just reading about it.The experience is emotional，speaking more to our instinct than our intellect.The possibilities for storytelling here are legion，and any storyteller wanting to do something more interesting than their peerould surely be considering the sheer power of VR.
   The question of virtual reality，though，is not how powerful it is.That is immediately apparent.The question of VR is one of viability and availability.Telling stories must be easy to do，and access to those stories must be readily available.This is the biggest challenge that VR faces.If the tools to tell a story with VR，aren't easy to pick up and learn，VR will fail.If VR technology isn't both top-of-the-line and affordable，VR will fail.
   Accessibility was one concern for Thomas Hallaq，assistant professor of journalism and mass communications，who.said that current VR technology，is pretty exclusive right now.Despite that，he said he doesn't think the exclusivity of this technology will be a problem in the long run.
   "I think it's very promising，" Hallaq said. "We're seeing more technology become accessible，and more people having access to that technology.Just look at smartphones." Like radio，TV and the Internet before it，virtual reality will change the way we tell stories.

（1）Why is VR considered a powerful tool for journalism？
A．Because it is an exclusively new tool.
B．Because it is very powerful and popular.
C．Because people can experience the story in person.
D．Because it is very fast，accurate and good-looking.
（2）According to the passage，what is the biggest challenge VR is facing？
A．How powerful and interesting it can be.
B．Whether people will have easy access to it.
C．Whether qualified VR headsets can be built.
D．What new ways people will find to deliver content.
（3）What's the author's attitude towards the future of VR technology？
A．Optimistic.
B．Neutral.
C．Pessimistic.
D．Concerned.
（4）Which of the following is the best title for the passage？
A．The Wide Popularity of Virtual Reality.
B．The Future Development of Virtual Reality.
C．Challenges and Hurdles of Virtual Reality.
D．Virtual Reality is the Future of Storytelling.

212734. （2025•西安三中•高二下期中）     ChatGPT developer OpenAI has introduced a new tool that it says can reproduce human voices with just a short audio sample.The tool is among several tools developed by technology companies that aim to clone voices with a high level of exactness.
    The system is called Voice Engine.OpenAI released details about Voice Engine on March 29.The company also released some examples of how the tool performs.The company explained in a statement that the system uses written instructions and a 15-second audio sample to produce，or generate natural-sounding speech in the voice of any speaker.
    OpenAI said it has been working on developing the tool since late 2022.It plans to continue developing it before releasing it to the public.The company said the delayed release represents a cautious and wise effort to prevent possible misuse.
    OpenAI said it began testing Voice Engine with a small group of trusted partners.This testing aims to help company officials decide how to improve the tool's safety and learn how it can "be used for good" across different industries.
    There have already been highly publicized examples of false，or fake voice recordings that sound like well-known people.
    OpenAI said it is currently discussing how to limit these and other risks of such voice cloning systems.Technology experts have also warned such tools can be used to carry out financial crimes.For example，voices can be recorded and then reproduced to represent another individual in an effort to carry out a fraud.
    However，OpenAI listed several possible uses for the technology tool.These include providing reading assistance to non-readers or children，supporting individuals who cannot speak，and helping patients recover their voice.
    The company said its Voice Engine system can work in several languages.One example of such use is taking an English voice recording and producing a new audio version in another language.In an example released online，OpenAI proved a person's voice and style of speaking can remain the same in other targeted languages.

（1）What's the main function of OpenAI's new tool？
A.To help the disabled.
B.To clone human voices.
C.To chat on the Internet.
D.To make records of sounds.
（2）Why has the release of Voice Engine been put off？
A.To ensure its safety.
B.To overcome its errors.
C.To ask for user feedback.
D.To wait for official permission.
（3）What does the underlined word "fraud" in paragraph 6 mean？
A.Task.
B.Investigation.
C.Cheat.
D.Test.
（4）What do we know about Voice Engine？
A.It can translate languages exactly.
B.It can teach children how to read.
C.It can make language study easier.

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.
