212913. （2024•周至四中•高二下期中） In today's difficult economic time，it's natural to rethink your goal of studying abroad．Does the benefit outweigh the cost？The answer，in fact，is yes，when you look at the road ahead．
   When the economy becomes more challenged，competition for the workforce increases，and employers look for employees with the best credentials（资力）．Having an overseas degree - from a university where strong English skills are required - can make all the difference．The added expertise of a foreign degree，along with more cultural experience，can make you more qualified for many jobs．
   A 50-year study of 3，400 studentows that studying abroad is usually a defining moment in a young person's life and continues to impact the participant's life for years after the experience．
   82% said that they acquired skills that influenced their career path．70% stated that it ignited（点燃）an interest in a career direction that they pursued after the experience．
   And the effect on one's career can be equally strong．A study by the Queensland，Australia government showed：
   61% of employers stated overseas studying experience was positive on a graduate resume．72% of employers felt that a second language made a graduate a more attractive employee．
   Still，there's the question of how to pay for studying overseas．But the cost doesn't have to be as high as you think．Scholarships may be available to cover some or all of these costs．And，there are plenty of ways to further offset（抵消）the cost - through financial tips，advice and grants（补助金）．

（1）The second study shows that studying abroad       ．
A．helps one to get a job
B．affects one's whole life
C．affects one's career direction
D．helps one to make more money
（2）The author tries to prove his idea by       ．
A．giving examples
B．answering questions
C．listing facts and numbers
D．offering advice and solutions
（3）What does the author think about the university fees？
A．Financial tips must increase the university fees．
B．Scholarships can cover some of the costs．
C．Money is a serious problem for studying abroad．
D．There are few ways for the students to earn money．
（4）What does the author intend to tell us in the passage？
A．Studying abroad is easy．
B．Studying abroad is rewarding．
C．The effects of studying abroad．
D．The problems with studying abroad．

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

201549. （2025•西安中学•一模）     Elon Musk has offered a prize of ＄100 m for the best carbon capture proposal.I can save his committee a lot of time.The money should go to Peter Wohlleben，whose book The Hidden Life of Trees was the most encouraging blockbuster of 2015.Wohlleben's idea is this：do nothing about trees.Stop fiddling with them，thinking that we can deal with climate change better than nature.If we fiddle，our Romes will burn.
    The Hidden Life of Trees argued that trees are social.It shows that they can be our saviors.But it's terribly hard to let ourselves be saved.We think we can be the authors of our salvation（拯救）.Of course，there are things we could and should be doing，but in terms of forestry practice，often what's billed as part of the solution is part of the problem.
    Anyone who has planted a tree in their garden knows that it has a far-reaching effect—it makes your garden cooler in summer and warmer in winter.Forests cool by transpiring（蒸发）.If there's no water，there's no cooling.Drought can kill trees fast，but trees have many ways of dealing with it，and Wohlleben sets them out.As a species，we have survived many climatic changes by changing our behavior—and that's how trees survive，too.Trees learn from their past harms and produce younger ones programmed with those lessons.They regulate their growth by changing the rate at which they drip（点滴）-feed them with sugar solution through root networks.
    Deciduous（落叶的） forests in particular remove greenhouse gases effectively as long as they live.Cut them down and burn them and you're releasing carbon dioxide not just from the wood，but also from the forest floor.Deciduous trees are not"harvest-ready"at200 years：they are teenagers.We must interrogate comforting expressions such as"renewable energy"，and learn the real cost of our toilet paper.
    If we don't learn to do nothing about trees，they will eventually be alone anyway—but without us.Wohlleben brilliantly and readably shows us how urgent and how hard it is to do nothing.

（1）What does Wohlleben suggest for carbon capture？
A.Fight climate change.
B.Leave trees alone.
C.Save the earth.
D.Change forestry species.
（2）How do trees survive the drought？
A.They slow their growth.
B.They lose all their leaves.
C.They stop absorbing water.
D.They get help from humans.
（3）What can we infer from the text？
A.We can cope with climate change successfully.
B.Trees can adjust their growth by themselves.
C.It is hard to stop releasing carbon dioxide.
D.It is urgent to regulate the growth of trees.
（4）What is the author's purpose in writing the text？
A.To illustrate the carbon capture system.
B.To give an account of the survival of trees.
C.To clarify a proposal for a reward.
D.To recommend a book.

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.
C．To obtain more chances and better working efficiency.
D．To create a harmonious working environment for themselves.
（2）What can we learn from paragraph 4？        ?
A．Most women don't like international jobs.
B．Educational systems contribute to the gender gap in English proficiency.
C．Women's English proficiency decreases with age.
D．There widely exists the phenomenon of discrimination against women.
（3）What's Jeannie Tse's attitude to the role of AI and face-to-face teaching？        ?
A．Objective.
B．Positive.
C．Uncertain.
D．Uncaring.
（4）What is a suitable title for the text？        ?
A．Young People's Attitudes towards English Vary
B．English Learning Has Become a Burden Worldwide
C．Results from a Report Show some Alarming Problems
D．Young People's English Language Ability Is Decreasing

201805. （2024•西安中学•七模）     Meeting people is the first step to make friends.But how do you actually become friends with someone？Here are some useful tips.
   1.Make small talk even if you don't feel like it
    Small talk can feel false and meaningless.But it does have a purpose.By making small talk，you show that you're friendly and open to communicating.In that way，small talk helps you to make the first connection with potential new friends.If someone doesn't make any small talk，we might assume that they don't want to make friends with us，that they don't like us，or that they're in a bad mood.
   2.Figure out what you might have in common
    When you talk to someone new and realize that you have things in common，the conversation usually goes from stiff to fun and interesting.Therefore，make it a habit to find out if you have any mutual interests or something in common.You can do this by mentioning things that interest you and seeing how they react.
   3.Don't write people off until you know them
    Don't judge people too quickly.Try not to assume that they are shallow，boring，or that you have nothing to talk about.If everyone seems uninterested，it might be because you keep getting stuck in small talk.If you only make small talk，everyone soundallow.
   4.Make people like being around you
    When you try to make people like you，it will become easier for you to make friends.When you make sure that people like being around you，they will like you.If we are with someone with a positive experience，we like that person more.

201806. （2024•西安中学•七模）     Charles Darwin was born in 1809 in Shrewsbury，England.His father，a doctor，had high hopes that his son would earn a medical degree at Edinburgh University in Scotland，where he was admitted at the age of sixteen.It turned out that Darwin was more interested in natural history than medicine.While he continued his studies at Cambridge，it was his focus on natural history that became his passion.
    In 1831，Darwin set out on a voyage as a naturalist aboard a ship of the British Royal Navy，the HMS Beagle.The main purpose of the trip was to survey the coastline of South America and chart its harbors to make better maps of the region.
    Darwin spent much of the trip on land collecting samples of plants，animals，rocks，and fossils.He explored regions in Brazil，Argentina，Chile，and remote islands such as the Galápagos.He packed all of his samples into large wooden containers and sent them back to England aboard other large ships.
    Upon his return to England in 1836，Darwin's work continued.Studies of his samples and notes from the trip led to groundbreaking scientific discoveries.Fossils he collected led to advances in the understanding of the processes that shape the Earth's surface.Darwin's analysis of the plants and animals he gathered led him to question how species form and change over time.This work convinced him of the insight that he is most famous for —natural selection.The theory of natural selection says that individuals of a species are more likely to survive in their environment and pass on their genes to the next generation when they inherit traits from their parents that are best suited for that specific environment.In this way，such traits become more widespread in the species and can lead eventually to the development of a new species.
    In 1859，Darwin published his thoughts about evolution and natural selection in On the Origin of Species.The book convinced many people that species change over time —a lot of time—suggesting that the planet was much older than what was commonly believed at the time：six thousand years.
    Charles Darwin died in 1882 at the age of seventy-three.He is buried in Westminster Abbey in London，England.

（1）What is the purpose of Paragraph 1？
A.To show his educational level.
B.To stress his father's influence on him.
C.To pave the way for his future study of nature.
D.To introduce his family background.
（2）What was Charles Darwin's attitude to his job as naturalist？
A.Boring.
B.Enthusiastic.
C.Unclear.
D.Disappointing.
（3）What kind of animal is more likely to survive according to natural selection？
A.An animal that can pass on its genes to the next generation.
B.An animal that can lead to the development of a new kind of species.
C.An animal that receives its parents' features fit for the specific environment.
D.An animal whose parents teach it to survive from the specific environment.
（4）What is this text mainly about？
A.The process of Darwin's voyage.
B.All the research results in Darwin's life.
C.The birth of Darwin's theory of natural selection.
D.Darwin's talent for studying natural history.

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.

201808. （2024•西安中学•七模）     In a new study，researchers found that invasive insects in the United States could kill approximately 1.4 million urban trees by 2050，which would cost over ＄900 million to replace，reports Vishwam Sankaran for the Independent.
    Hot spots predicted to have the most urban tree mortality（死亡率） were Milwaukee，Wisconsin；Chicago，Illinois；and New York，New York.The study，published in the Journal of Applied Ecology，is the first nationwide forecast of street tree mortality from invasive insects.
    The emerald ash borer is an invasive beetle native to Asia.It was first detected in 2002 in southeastern Michigan，and experts suspect it was brought into the United States on wood packing material carried on cargo ships or airplanes traveling from Asia.Since then，the bug has been damaging ash trees.In the last two decades since the insect was first detected，numerous trees have been killed in North America.
    Data collected from 30，000 communities across the country was used to estimate tree mortality in the next 30 years.The researchers combined this data with a model that predicted the spread of 57 different invasive insect species.Their resultow emerald ash borers alone could cause 90% of the estimated 1.4 million tree deaths.Ash borers are already predicted to "kill virtually all ash trees" in over 6，000 urban areas，according to Newsweek.
    Less than 25% of 30，000 urban areas in the U.S.are expected to experience 95% of all street-tree mortality，reports Adam Barnes for the Hill.The areas that will experience the most tree loss include cities in the Midwest and East Coast.These locations are expected to have the most tree loss because large numbers of ash trees occupy the streets and parks in these areas，reported the Independent.
    When it comes to how to save urban areas from becoming treeless，study author Emma Hudgins，a biologist at McGill University，says， "These results can hopefully provide a cautionary tale against planting a single species of tree throughout entire cities，as has been done with ash trees in North America.Planting various trees provides resilience against pest infestations（侵扰）."

（1）What can we know about the emerald ash borer？
A.It is an invasive beetle in Asia.
B.It was first found by the Michigan people.
C.It has killed numerous trees in America.
D.They definitely enter the U.S.by cargo ships or airplanes.
（2）What is the fourth paragraph intended to describe？
A.The purpose of the research.
B.The conclusion of the research.
C.The significance of the research.
D.The process and result of the research.
（3）What can be inferred from the fifth paragraph？
A.Pest infestations are taking place across the country.
B.The insect's invasion won't spread equally in America.
C.Tree loss is the main cause of environmental problems.
D.Ash trees are being removed from many areas in the U.S.
（4）What suggestion does Emma Hudgins provide？
A.Getting different types of trees planted.
B.Replacing foreign trees with local ones.
C.Getting more trees planted in more areas.
D.Planting trees resistant to pest infestations.

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.
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.

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

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

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.
D.The Marine Protected Area has played an important role in protecting fishes.

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
