203715. （2024•西安中学•高二下期末）     Australia is proud of a unique history that has been shaped by the diversity of her inhabitants.The three main elements that have been central to the creation of Australia's population composition are the diversity of her native population，colonization by the British in the past and the extensive immigration from diverse cultures.
    Australia is home to the world's cultures and inhabitants who can identify with more than 270 ancestries （祖先）.From the year 1945，the number of people who have immigrated to Australia from different parts of the globe is approximately seven million.The country considers the rich cultural diversity as its main strength which embodies its national identity.
    In 1975，there was the racial discrimination （歧视） act，which meant that discrimination in the country was against the law.Later in 1995，the act was extended to ensure that any acts of racial hatred （仇恨） were against the law.To date，the act has been used in ensuring that Australia sends a strong message on the collective commitment to promoting racial equality and the significance of fairness for all.
    On a range of measures，Australia is a multicultural success story.On educational attainment，studieow that children of immigrants in Australia get better average results than children of native-born Australians.This is significant because according to research conducted by the OECD，the successful integration of immigrant students is an important indicator of a country's success in its education system and equity and broader socially combinative policies.
    The success in educational performance is mirrored in the broader economy of Australia as it attracts a significant proportion of skilled migrants annually who have a high labour market participation rate.In the year between 2016-2017，skilled migrants accounted for 67.3 percent of the total immigration program outcome that year.The net effect of a multiculturalism policy for Australia has been a brain gain for Australia and this is expected to continue growing.

（1）What is paragraph 1 mainly about？
A.The history of Australia.
B.The customs of Australia.
C.The character of Australians.
D.The population structure of Australia.
（2）What does the underlined word "embodies" in paragraph 2 mean？
A.Maintains.
B.Represents.
C.Assesses.
D.Predicts.
（3）From which can we see Australia's success in education？
A.The higher educational standards.
B.The better overall grades of students.
C.The increasing number of immigrant children.
D.The better performance of immigrant children.
（4）In which aspect does educational success benefit Australia？
A.Bringing in more skilled migrants.
B.Reforming the immigration policy.
C.Developing immigration programs.

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

（1）Why are working adults trying to improve their English？        ?
A．To increase their income and knowledge.
B．To be involved in better working environment.

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

（1）Why does the author mention the story of a farmer in the first paragraph？
A．To show the power of volcano eruption.
B．To introduce the topic.
C．To introduce the volcano Paricutin.
D．To explain the reason.
（2）What does the underlined word "they" in paragraph 2 refer to？
A．The bubbles of CO₂ .
B．The ash of the volcano.
C．Gas bubbles of compounds.
D．The elements of a soda.
（3）Which of the following is true about the eruption of Mount St.Helens？
A．Landslideould be responsible for its eruption.
B．It began to explode over a long period of time.
C．The process of "unloading" occurred after its explosion.
D．The weight of the rock above it increased as to cause its eruption.
（4）What can we infer from the last paragraph？
A．Scientists can determine the eruption of volcano in advance.
B．It is quite difficult to measure the weight of the Earth's crust.
C．Spectrometers can help scientists to detect underground hotspots.
D．Scientists are positive about further study of volcano eruption.

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

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

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

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

201550. （2025•西安中学•一模）     As part of a post-fire response and recovery project，the Debris Flow Hazard Team（泥石流危害小组） is engaging in several studies to better understand the drivers of post-fire debris flows and improve post-fire hazard assessments across the Pacific Northwest.Wildfires make debris flows easy to happen，a fast-moving mixture of water，soil，and rock that can cause property damage and loss of life.
    After a wildfire，emergency managers need rapid answers to the questions：Where are debris flows likely？How much rain will it take to cause a debris flow？And how big will that debris flow be？Researchers are conducting applied research and emergency hazard assessments to answer these questions.Evaluated burn areas they've assessed included the nearly 2021 Dixie fire，the 2020 Labor Day wildfires，and many of the 2021 wildfires in Washington.
    The models used for hazard assessment have been developed and tested in drier places.But the models have not been tested widely in wetter places.Are the models accurate for wetter regions？Researchers have begun monitoring post-fire debris-flow activity in wetter places to answer the question.Post-fire monitoring involves measuring the rainfall within the burned areas and recording the flow response after rainstorms.The observed flow response is compared to the predicted possibility.If the model predicted a high possibility of debris flow and there was a debris flow，the model got it right.
    Recent data bespeaks both similarities and differences in debris-flow processes between the areas with higher humidity（湿度） and drier areas.For example，in the 2021 Dixie fire，major debris flows were caused by short bursts of intense rainfall like they are in drier places.In contrast，debris flows in the 2017 Eagle Creek Fire were caused by long time rainfall.Continued observation and testing is expected to lead to an improved set of hazard assessment models.
    Other frequently asked questions after wildfires are：How far will debris flows travel？What will be impacted？And how long will the burned areas remain dangerous？These questions are presently not resolved in current debris-flow hazard assessments，but the researchers are doing research to provide answers soon.

（1）What is the first paragraph mainly about？
A.Contents included in a project.
B.Hazards caused by debris flows.
C.Causes of post-fire debris flows.
D.Reasons for conducting the studies.
（2）What places are current studies focusing on？
A.Places seldom noticed.
B.Places with debris flow records.
C.Places with higher humidity.
D.Places once affected by wildfires.
（3）What does the underlined word"bespeaks"mean in paragraph 4？
A.Replaces.
B.Reveals.
C.Recognizes.
D.Recommends.
（4）What may be included in the next studies according to the text？
A.Methods to prevent debris flows.
B.Possible effects of debris flows.
C.The lasting time of the debris flows.
D.Other risks in the burned areas.

201825. （2024•西安中学•九模）     From the world's last seven to a global population of more than 5，000，China spent nearly 40 years bringing back crested ibises（朱鹗）from the edge of extinction.
    With its typical red crest and face，as well as a long black mouth and snow-white feathers，the crested ibis is known as "the oriental gem" in China.They were once widespread in East Asia and Siberia until the 20th century when hunting，ecological damage and increased human activities drove the birds to near extinction.
    In 1981，the entire species around the world was down to the seven crested ibises which were found only in Yangxian County，northwest China's Shaanxi Province，and deep in the Qinling Mountains，making Qinling，a natural boundary between China's north and south，the last shelter of the wild birds.
    Since 1981，the local government of Yangxian County has put forward four bans for the protection of the species，prohibiting activities including hunting in the birds' living areas，cutting down trees where they nest，using chemicals in their food-finding areas，and firing guns in their breeding（繁殖）areas.The Chinese government arranged special funds to protect the habitat of crested ibises，sealing off mountains to plant trees in the birds' living areas.China started the artificial breeding of crested ibises in 1991 and had bred more than 400 birds in Shaanxi as of last year.
    Years of constant effort have brought promising results.It is estimated that there are more than 5，000 crested ibises in the world now，and a majority of them live in Shaanxi.The bird's habitat in China has risen from less than 5 square km in 1981 to the current 15，000 square km.
    "It is lucky that the crested ibis，an ancient bird，is still flying around，" said Zan Linsen，head of the Shaanxi Academy of Forestry. "The conservation story of crested ibises not only shows us the power of ancient life，but also the necessity and urgency of ecological environment protection."

（1）Why are the Qinling Mountains so important to crested ibises？
A．They are where crested ibises were first found.
B．They used to be the last habitat of crested ibises.
C．They are the only breeding area of crested ibises.
D．They protect crested ibises from natural enemies.
（2）What can we conclude from paragraph 4？
A．Crested ibises are unlikely to be bred artificially.
B．It's legal to own hunting guns in Yangxian County.
C．Hunting has been the biggest threat to crested ibises.
D．The government plays a key role in saving crested ibises.
（3）How does Zan Linsen feel about the conservation of crested ibises？
A．Merciful and ambitious.
B．Relieved and happy.
C．Shocked and curious.
D．Sorry and regretful.
（4）What is a suitable title for the text？
A．Rare animals in China：crested ibises
B．Artificial breeding of crested ibises in China
C．Endangered crested ibises making a comeback
D．Crested ibises found again in the Qinling Mountains

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

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

201846. （2024•西安一中•二模）     Once known as "the sea of death"，the Taklimakan Desert has become a driving force for green development in northwest China's Xinjiang Uygur Autonomous Region.In recent years，photovoltaic （光电池的） stations have been constructed and large gardens of vegetation such as roses have appeared on the outskirts of this vast desert.This transformation has positioned （使处于） the desert as a flourishing center of sustainable development.
    Under the sun's rays，rows of PV panels （面板） that generate electricity look like a blue ocean.Tian Juxiong，head of a power station in Lop County，regularly inspects these power generation systems and monitors their daily operations on the control center's screen.This station produces 360 million kWh of electricity annually and can meet the residential electricity needs of the 25.9 million residents of Xinjiang for around 10 days.Every year，it saves approximately 110，000 tonnes of standard coal and reduces 330，000 tonnes of carbon dioxide.
    The project is also equipped with an energy storage system with a capacity of 80，000 kWh.In rainy conditions when the station cannot generate electricity，the storage facility acts as a power bank，providing energy for about two hours.Most PV and wind power stations in southern Xinjiang are equipped with storage systems to ensure a stable supply of renewable energy.
    "By May，the total installed capacity for renewable energy in Xinjiang had passed 8，400 megawatts （兆瓦） and an additional 8，259 megawatts of new energy facilities are currently under construction，" according to Ding Biwei，who is responsible for grid connect ion of new energy at State Grid's Xinjiang branch.

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

（1）What is the role of fossils in the modern times？        ?
A．To help protect our environment.
B．To help explore the function of the Earth.

（2）Which of the following is the first step of fossilization？        ?
A．The quick pressure caused by rocks.
B．The quick transformation of the remains.
C．The rapid burial of the remains.
D．The mix of groundwater and minerals.
（3）How can a good copy of organisms form？        ?
A．By fossils petrified when minerals replace the organic material.
B．By groundwater moving through them.
C．By accumulating more pressure on them.
D．By creating a protective environment.

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

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

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

201807. （2024•西安中学•七模）     Harvard scientists have engineered a group of fish that swims autonomously.Researchers say the experiment could advance pacemaker（起搏器） technology and improve the development of artificial hearts for humans.
    Researchers built the fish using paper，two parts of heart muscle tissue —one on the left side and one on the right —and a plastic fin.A contraction on one side caused the muscle on the other side to stretch.The stretching then caused those cells to contract，which moved the tail from side to side and allowed it to swim on its own.The muscle cells were from human stem cells.The researchers also engineered an autonomous pacing node，which acted like a pacemaker by controlling the rhythm and frequency of the contractions.
    The fish moved autonomously for over 108 days，which is equal to 38 million beats，the study states.Because heart cells constantly rebuild themselves，which takes about 20 days，the fish cells rebuilt themselves a total of about five times over，says Kit Parker，a professor from Harvard University who led the research.
    Years ago，Parker was disappointed with the state of heart treatment. "It occurred to me in 2007 that we might have failed to understand the fundamental laws of muscular pumps，" he said in a 2012 statement.Then，on a trip to the museum with his daughter，he spotted a special fish. "I'm looking at it，thinking， 'It pumps，it looks like a heart pump，and I could build that thing.'" In 2012，his team created a fish that swam using rat heart cells，and then a ray fish with rat heart cells in 2016.
    Though the researchers say the fish is a step forward for heart research，it could be years before it leads to the creation of an artificial heart，says Michael Schneider，a professor at Imperial College London，who wasn't involved in the study.But that doesn't dismay Parker. "I think other methods will be faster than us，" says Parker. "But in the long run，creating tissue that relies on the patient's own cells could offer unexpected benefits."

（1）What made the fish swim autonomously in the experiment？
A.The special paper.
B.The push of the fin.
C.Muscle contractions.
D.The support of the tail.
（2）What result probably impressed the researchers most？
A.The power of the pacing node.
B.The swimming speed of the fish.
C.The fish's lasting swimming time.
D.The rhythm of the fish's movement.
（3）Why is Parker's trip to the museum mentioned in Paragraph 4？
A.It gave Parker a good memory.
B.It made Parker find inspiration.
C.It removed Parker's disappointment.
D.It introduced Parker to a special fish.
（4）What does the underlined word "dismay" mean in the last paragraph？
A.Depress.
B.Annoy.
C.Embarrass.
D.Relieve.

201920. （2024•临潼区•二模）     How to release your art potential？Traditionally，people may bury themselves in learning painting skills at a studio and begin from drawing lines.However，Maggie Wiebe，a 21-year-old girl from Stamps School of Art & Design at the University of Michigan，has her own method.
    Wiebe and her school friend Jessie Rice are trying to do something that shows their love for art and also benefits the environment.For the past year or so，they have tended a garden at their campus farm，planting a variety of colorful flowers，as well as flax（亚麻）to make linen and paper to be used in art.
    Inspired by a group of old ladies in Canada who plant sustainable art materials and post their videos on social platform YouTube，Wiebe learned about how to plant，harvest and separate fibers.She planted different fruits and vegetables traditionally used to dye（给……染色）fabrics.She then put their peels（外皮）into boiled water and added hot pressurized air to make a dye.For her，it's a demanding but enjoyable process.
    Wiebe and Rice plan to eventually buy some land in Detroit to grow these sustainable art materials—a dye，fiber and pigment garden—"a bigger version of what we're already doing"，Wiebe told Minnesota News."We'd set it up like an organization where artists can volunteer a few hours a week and then use all of the plants that we grow."
    Wiebe also likes fiber-based art，such as quilting，weaving and sewing.She has applied those techniques to her recent works，displayed as part of the annual Senior Exhibition at her school.During her sophomore year，Wiebe joined the Michigan Daily as an illustrator，learning to conceptualize and complete complex illustrations on tight deadlines.Wiebe's works received a lot of help from others."Because the art school doesn't have departments，we have studio coordinators who take care of each studio." she said."I see them every day，and they've helped me a lot."

（1）What can we learn about Wiebe from the first two paragraphs？
A.She longed to be a gardener.
B.Her parents taught her how to plant.
C.She was fond of drawing lines.
D.She had an environmentally friendly mind.
（2）What did Wiebe learn from watching videos？
A.To peel fabric s skillfully.
B.To get fibers eventually.
C.To grow plants traditionally.
D.To dye fabric s individually.
（3）Why is Detroit referred to in Paragraph 4？
A.To present Wiebe's patience.
B.To review Wiebe's career.
C.To display Wiebe's future prospect.
D.To promote an application of Wiebe's idea.
（4）Which of the following best describes Wiebe's work？
A.Creativity is productivity.
B.Practice makes perfect.
C.Unity is strength.
D.Curiosity is motivation.
