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

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

（1）细节理解题。根据第一段Dreams，according to Carl Jung，reveal a certain amount of reality hidden during waking consciousness.In Jungian philosophy，the conflict and chaos experienced in dreams finally bring order to our lives. （根据卡尔•荣格的说法，梦揭示了在清醒意识中隐藏的一定数量的现实。在荣格哲学中，梦中经历的冲突和混乱最终给我们的生活带来了秩序）可知，卡尔•荣格认为梦反映事实。故选D。
（2）推理判断题。根据第三段You might think this is just a sleep problem，but dreaming is inseparable from our nighttime rest. （你可能认为这只是睡眠问题，但做梦与夜间休息是分不开的）以及The longer we sleep，the more time we spend in REM，which is why we are often dreaming when waking up in the morning.If we sleep less than seven hours，however，it becomes harder to achieve this level of REM. （我们睡得越久，在快速眼动阶段（做梦）的时间就越多，这就是为什么我们早上醒来时经常做梦。然而，如果我们的睡眠时间少于7小时，就很难达到这种程度的快速眼动）可知，第三段解释睡眠过程，是为了证明做梦问题和睡眠问题是联系在一起的。故选C。
（3）推理判断题。根据第五段Volunteers that experienced more REM sleep were better equipped for solving problems requiring creative solutions. （经历了更多快速眼动睡眠的志愿者更善于解决需要创造性解决方案的问题）可知，经历更多快速眼动睡眠的志愿者更有创造力。故选A。
（4）主旨大意题。根据第一段While Jung's mystical theories are debatable，he was not mistaken about the importance of dreaming.A growing number of reports show that a continuous lack of dreaming is damaging our waking hours in many ways. （虽然荣格的神秘主义理论是有争议的，但他对做梦的重要性的认识并没有错。越来越多的报告显示，持续缺乏做梦正在从很多方面损害我们清醒的时间）并结合全文可知，文章主要讲了不做梦对于我们来说是可怕的。故选B。

201569. （2025•西工大附中•十一模）     The ability to connect an event with its consequences-experts use the term associative learning-is a crucial skill for adapting to the environment.Recent findingow that adults fail to demonstrate the highest learning performance in this area.This paves the way for a fresh perspective on associative learning disorders，which are linked to the development of mental illness later in life.
    Researchers from Ruhr University Bochum conducted groundbreaking experiments across four age groups：babies（0-3），primary school children （6-12），teenagers（13-19），and adults.Participants were required to identify patterns between visual pictures and corresponding rewards through computer-based tasks.Several learning sessions were then integrated to assess performance stability.
    The research team was amazed by the results：""We'd initially assumed that associative learning improves continuously with increasing age，"says Dr.Carolin Konrad.However，there was a clear peak in performance at primary school："Children at this age achieved the best results，learned most consistently and showed the least variability in their learning behavior." Although adults and teenagers learned faster than babies，they didn't reach the performance level of primary school children.
    It also emerged that repeated exposure to the learned material plays a crucial role for babies and teenagers since an additional learning session led to an improvement in learning performance in these age groups.Teenagers improved 40% after additional practice sessions，whereas adultowed minimal progress.This finding highlights the"sensitive period"phenomenon-the brain's higher plasticity during childhood that allows more efficient knowledge strength.
    The study shows that associative learning is present across the lifespan but that the rates and quantities of learning vary."This mental capacity not only helps us avoid dangers but also influences emotional regulation patterns，"concludes Konrad. "Early identification of associative learning difficulties could serve as an indicator for future mental health risks."

（1）Which is an example of associative learning？
A.A baby grasps an object placed in its hand.
B.A student works harder after getting good grades.
C.A driver keeps speeding up when receiving a ticket.
D.A cook follows his recipe despite customer complaints.
（2）What were the participants required to do in the experiments？
A.Identify the relationship between different groups.
B.Watch and record their own performance over time.
C.Assess their learning progress during the sessions.
D.Pair pictures with rewards through computer-based tasks.
（3）What surprised the researchers about associative learning？
A.Adults possessed greater adaptability.
B.Primary schoolers outperformed others.
C.Teenagers peaked in learning performance.
D.Babies required frequent exposure to knowledge.
（4）Why is the"sensitive period"phenomenon mentioned in paragraph 4？
A.To show learning ability differences across all ages.
B.To advise adults to learn efficiently in a gradual way.
C.To stress the significance of learning during childhood.
D.To demonstrate the brain's ability to adapt in adulthood.

201789. （2024•西安中学•五模）     Research has found that using wood for construction instead of concrete and steel can reduce emissions.But Tim Searchinger at Princeton University says many of these studies are based on the false foundation that harvesting wood is carbon neutral （碳中和）. "Only a small percentage of the wood gets into a timber （木料） product，and a part of that gets into a timber product that can replace concrete and steel in a building，" he says.Efficiencies vary in different countries，but large amounts of a harvested tree are left to be divided into parts，used in short-lived products like paper or burned for energy，all of which generate emissions.
    In a report for the World Resources Institute，Searchinger and his colleagues have modelled how using more wood for construction would affect emissions between 2010 and 2050，accounting for the emissions from harvesting the wood.They considered various types of forests and parts of wood going towards construction.They also factored in the emissions savings from replacing concrete and steel.
    Under some circumstances，the researchers found significant emissions reductions.But each case required what they considered an unrealistically high portion of the wood going towards construction，as well as rapid growth only seen in warmer places，like Brazil.In general，they found a large increase in global demand for wood would probably lead to rising emissions for decades.Accounting for emissions in this way，the researchers reported in a related paper that increasing forest harvests between 2010 and 2050 would add emissions equal to roughly 10 percent of total annual emissions.
    Ali Amiri at Aalto University in Finland says the report's conclusions about emissions from rising demand are probably correct，but the story is different for wood we already harvest. "Boosting the efficiency of current harvests and using more wood for longer lived purposes than paper would cut emissions，" he says. "We cannot just say we should stop using wood."

（1）What is wrong with previous researches according to Searchinger？
A．They got wrong statistics.
B．They used an incorrect concept.
C．They included too many factors.
D．They were applied in limited countries.
（2）What does paragraph 2 mainly talk about？
A．The process of the new research.
B．The background of the new study.
C．The challenge of the new research.
D．The achievements of the new study.
（3）When will the emissions drop off greatly according to the new study？
A．When wood grows slowly.
B．When wood is used to make paper.
C．When wood is used to build a house.
D．When wood is harvested in countries like Brazil.
（4）What is Ali Amiri's attitude toward the new result？
A．Favorable.
B．Doubtful.
C．Critical.
D．Objective.

201760. （2024•西安中学•三模）     If humans were truly at home under the light of the moon and stars，we would go in darkness happily，the midnight world as visible to us as it is to the vast number of nocturnal（夜间活动）species on this planet.Instead，we are diurnal creatures，with eyes adapted to living in the sun's light.This is a basic evolutionary fact，even though most of us don't think of ourselves as diurnal beings.Yet it's the only way to explain what we've done to the night：We've engineered it to receive us by filling it with light.
    The benefits of this kind of engineering come with consequences—called light pollution—whose effects scientists are only now beginning to study.Light pollution is largely the result of bad lighting design，which allows artificial light to shine outward and upward into the sky.Ill-designed lighting washes out the darkness of night and completely changes the light levels—and light rhythms—to which many forms of life，including ourselves，have adapted.Wherever human light spills into the natural world，some aspect of life is affected.
    In most cities the sky looks as though it has been emptied of stars，leaving behind a vacant haze（霾）that mirrors our fear of the dark.We've grown so used to this orange haze that the original glory of an unlit night—dark enough for the planet Venus to throw shadows on Earth—is wholly beyond our experience，beyond memory almost.
    We've lit up the night as if it were an unoccupied country，when nothing could be further from the truth.Among mammals alone，the number of nocturnal species is astonishing.Light is a powerful biological force，and on many species it acts as a magnet.The effect is so powerful that scientists speak of songbirds and seabirds being "captured" by searchlights on land or by the light from gas flares on marine oil platforms.Migrating at night，birds tend to collide with brightly lit tall buildings.
    Frogs living near brightly lit highways suffer nocturnal light levels that are as much as a million times brighter than normal，throwing nearly every aspect of their behavior out of joint，including their nighttime breeding choruses.Humans are no less trapped by light pollution than the frogs.Like most other creatures，we do need darkness.Darkness is as essential to our biological welfare，to our internal clockwork，as light itself.
    Living in a glare of our own making，we have cut ourselves off from our evolutionary and cultural heritage—the light of the stars and the rhythms of day and night.In a very real sense，light pollution causes us to lose sight of our true place in the universe，to forget the scale of our being，which is best measured against the dimensions of a deep night with the Milky Way—the edge of our galaxy—arching overhead.

（1）According to the passage，human beings         .
A.prefer to live in the darkness
B.are used to living in the day light
C.were curious about the midnight world
D.had to stay at home with the light of the moon
（2）What does the underlined word "it" （Paragraph 1）most probably refer to？
A.The night.
B.The moon.
C.The sky.
D.The planet.
（3）The writer mentions birds and frogs to         .
A.provide examples of animal protection
B.show how light pollution affects animals
C.compare the living habits of both species
D.explain why the number of certain species has declined
（4）What might be the best title for the passage？
A.The Magic Light
B.The Orange Haze
C.The Disappearing Night

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.
C．To enhance knowing the long history of the universe.
D．To provide an insight into the diverse life forms.
（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.
（4）What's the text mainly about？        ?
A．The importance of fossils.
B．The process of fossilization.
C．The evolution of ancient animals.
D．The preservation of the remains.

201827. （2024•西安中学•九模）     The view you adopt for yourself significantly affects the way you lead your life.It can determine whether you become the person you want to be and whether you achieve the things you value.How does this happen？How can a simple belief have the power to transform your psychology and，as a result，your life？
    Believing that your qualities are carved in stone-the fixed mindset-create s an urgency to prove yourself over and over.Some of us are trained in this mindset from an early age.Even as a child，I was focused on being smart，but the fixed mindset was really stamped in by Mrs Wilson，my sixth grade teacher.She believed that people's IQ scores told the whole story of who they were.We were seated around the room in IQ order，and only the highest-IQ students could be trusted to collect homework，or take a note to the principal.She was creating a mindset in which everyone in the class had one consuming goal—look smart，don't look stupid.
    I've seen so many people with this consuming goal of proving themselves—in the classroom，in their careers，and in their relationships.Every situation calls for a confirmation of their intelligence，personality，or character.Every situation is evaluated：Will I succeed or fail？Will I look smart or stupid？Will I feel like a winner or a loser？
    But doesn't our society value intelligence，personality，and character？Isn't it normal to want these qualities？Yes，but...
    There's another mindset，the growth mindset，which is based on the belief that your basic qualities are things you can develop through your efforts.Everyone can change and grow through efforts and experience.Did you know that Darwin and Tolstoy were considered ordinary children？That the photographer Cindy Sherman，who has been on almost every list of the most important artists of the twentieth century，failed her first photography course？
    You can see how the belief that valuable qualities can be developed creates a passion for learning.Why waste time proving how great you are，when you could be getting better？Why hide weaknesses instead of overcoming them？The passion for stretching yourself and sticking to it，even when it's not going well，is the feature of the growth mindset.This is the mindset that allows people to achieve success during some of the most challenging times in their lives.

（1）What is the author's attitude toward Mrs Wilson's way of teaching？
A.Unconcerned.
B.Sceptical.
C.Supportive.
D.Neutral.
（2）According to paragraph 5，the example of Darwin and Tolstoy shows that        .
A.success has nothing to do with natural gifts
B.achievements can be gained through hard work
C.It's difficult to predict one's future success
D.One single outcome defines our ability
（3）The author strongly believes that we should        .
A.carry out an honest evaluation of our qualities
B.See success as a proof of intelligence or talent
C.Focus on self-development rather than self-proving
D.Believe good things will happen during difficult times
（4）The main purpose of the passage is to        .
A.explain the differences between two mindsets
B.persuade people to adopt the right mindset
C.inform people of the influence of the mindset
D.advise people to access their mindset

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

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.

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

201824. （2024•西安中学•九模）     Having spent more than a decade on the dance floor，Niccolo Filippi，a 23-year-old Italian dance performer，recently decided to explore Chinese culture and its traditional dance forms and believes that this experience will not only boost his career，but also broaden his horizons beyond the world of dance.
    His interest in diversifying his skills grew after he stumbled upon a short video of traditional Chinese-style d dance on YouTube."I saw it as an art that combines tradition and modernity，which was mostly the reason why I liked it."says Filippi.
    Ever since，he has been closely following Chinese dance performers and watching numerous videos to learn more about the traditional style that he admires."I prefer the traditional style because of its light movements.It also reflects my personality with elegance，"he adds.

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.

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.

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

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？
