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.

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

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

201948. （2023•周至县•三模） A smile is the key to a thousand doors，but deploying （有效利用）it in every situation without mastery of its use is dangerous，says a new social science study.
   Scientists say it takes a great many muscles to smile；scientists at Queen's University Belfast in a recent study found that subtle（细微的）differences in the way in which a person smiled had not-so-subtle impacts on the opinions which the test participants had about the smiler. "Smiling at another person does not always lead to trust and cooperation，" said Dr.Stephanie Carpenter from the University of Michigan，a co-author of the study. "Subtle differences in a smile can definitely have a real impact on whether people trust each other and choose to cooperate.In fact，the way you smile in a good or bad situation can impact whether people trust you.
   "Think about movie villains（恶棍），for example in James Bond films，" said Dr.Magdalena Rychlowska from Queen's University，who led the research published in Cognition and Emotion journal. "They often make happy smiles when something bad has happened or is about to happen.This context makes these otherwise happy and normal smiles feel threatening and unpleasant." She adds，"The findings of this study show the power of subtle facial expressions and the positive consequences that an affiliation smile can have in difficult situations.It also highlights the importance of social context-a happy smile that could be read as a signal of trustworthiness in one setting can，but in another setting，it can be seen as the evidence of bad intentions."
   Mastery of the smile then，can be an excellent way of getting out of difficult social situations，while the lack thereof can be an excellent way of getting into one.

（1）Which of the following about smiling is right according to the passage？
A．Deploying smiling is very dangerous in every situation.
B．Subtle difference in smiling has little impact.
C．The way you smile will impact whether you can be trusted.
D．Smiling will always lead to trust and cooperation.
（2）How did the author explain subtle differences in a smile？
A．By using numbers and giving examples.
B．By giving examples and citing scientific proof.
C．By giving examples and making a comparison.
D．By making a comparison and citing scientific proof.
（3）What can be learn from the study of smiling？
A．A happy smile can always be read as a signal of trustworthiness.
B．People always make happy smiles when something bad has happened.
C．Mastering the smile can help you avoid troubles.
D．Subtle facial expressions have positive consequences.
（4）What is the best title for the text？
A．The advantages of smiling
B．The impact of smiling
C．A trusting smile
D．Subtle differences in smiling

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.

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？

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

201950. （2023•周至县•三模） Without cracking a single textbook，without spending a day in medical school，the co-author of a preprint study correctly answered enough questions that it would have passed the real US Medical Licensing Examination.But the test-taker wasn't a member of Mensa or a medical specialist；it was the artificial intelligence ChatGPT.The tool，which was created to answer user questions in a conversational manner，has generated so much buzz that doctors and scientists are trying to determine what its limitations are and what it could do for health and medicine.
   The medical licensing exam is generally considered one of the toughest of any profession because it not only tests basic science，medical knowledge，but also assesses clinical reasoning，ethics （道德观念），critical thinking and problem-solving skills.
   The AI passed all the parts of the exam without any specialized training，showing a high level of insight in its explanations.This greatly impressed Dr.Victor Tseng，a medical director of the California-based group and a co-author of the study. "Googling the answer is very difficult，" he explained. "Because there're a lot of red herrings on the Internet.It might take hours to get an accurate answer." But ChatGPT was able to do it within five seconds.
   The results of the medical licensing exam study were even written up with the help of ChatGPT.However，the journal Nature created guidelines that said no such program could be credited as an author because "any authorship carries with it accountability for the work，and AI tools cannot take such responsibility." Actually，AI is only as good as the information it's fed，and with so much inaccurate information available online about things like COVID-19 vaccines，it could use that to generate inaccurate results.
   Tseng said he ultimately thinks ChatGPT can enhance medical practice，but won't replace doctors.Tseng's group will continue to test it to learn why it creates certain errors and what other ethical factors need to be put in place before using it for real.
   "AI is here.The doors are open，" Tseng said. "I firmly believe that it will actually make me and make us as physicians and providers better."

（1）What can ChatGPT possibly do according to paragraph 1？
A．Study in medical school.
B．Start an online conversation.
C．Conduct a study independently.
D．Pass a challenging examination.
（2）What does underlined words "red herrings" in paragraph 3 refer to？
A．Appealing topics.
B．Efficient helpers.

201949. （2023•周至县•三模） A new study suggests classic paintings by well-known Impressionists Joseph Turner and Claude Monet may have been influenced by air pollution during the Industrial Revolution.
    The study，published in Proceedings of the National Academy of Sciences by authors from Harvard and Sorbonne universities，analyzed 60 oil paintings by Turner from 1796 to 1850 and 38 paintings by Monet from 1864 to 1901.
    Scientists don't know exactly how polluted the cities were during that time for lack of data.However，researchers say examining the works of Turner and Monet can give a picture of long-term environmental change with the air pollution.
    In particular，researchers said changes in local sulfur dioxide emissions from burning coal may explain changes in the colour contrast and intensity of Tuner，Monet，and others' works，even after taking into account the artistic trends and subject matter of the time.
    Scientists successfully measured painters' representation of nature，focusing on differences in local weather patterns which influenced colour in works painted in different parts of Europe.Paintings' done in Britain generally feature a paler blue sky than other works in other parts of the continent.Generally，artists can historically accurately represent their environment，so Turner and Monet were chosen because they are famous for their landscape and cityscape paintings and also because they were active during the Industrial Revolution，when air pollution grew at a rate never seen before.
    Additionally，researchers say that as the air in London and Paris became more polluted，the cities would appear hazier to the eyes as well as in photographs.By comparing the paintings of Turner and Monet to pictures from the era，they were able to determine the artists were at least partly influenced by the change in emissions.

（1）What did the researchers find in the works of Turner and Monet？
A．Change in subject matter.
B．Air pollution at that time.
C．Social trends of the period.
D．Development of photography.
（2）The researchers conduct the study by        .
A．referring to relevant historical records
B．comparing the paintings of Turner and Monet
C．relating the paintings to the air conditions then
D．analyzing the data during the Industrial Revolution
（3）What can we learn from Paragraph 5？
A．European artists preferred landscape paintings.
B．Scientists focused on studying weather patterns.
C．Turner and Monet intended to present pollution.
D．Britain suffered from air pollution most in Europe.
（4）What is the purpose of the text？
A．To inform people of a new discovery.
B．To instruct people to appreciate paintings.
C．To introduce the Industrial Revolution.
D．To call on people to protect the environment.

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.

（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.

201941. （2023•西安四十八中•一模） Science reporting on climate change does lead Americans to adopt more accurate beliefs and support government action on the issue，but these gains are fragile，a new study suggests.Researchers found that these accurate beliefs fade quickly when people are exposed to coverage skeptical of climate change.
   "It is not the case that the American public does not respond to scientifically informed reporting when they are exposed to it，" said Thomas Wood，associate professor of political science at the Ohio State University. "But even truly accurate science reporting recedes from people's frame of reference very quickly."
   Resultowed that accurate science reporting didn't persuade only politicians and people who initially rejected human-caused climate change also had their opinionifted by reading accurate articles.The study involved 2，898 online participants who participated in four waves of the experiment during the fall of 2020.
   In the first wave，they all read authentic articles in the popular media that provided information reflecting the seientifie views on climate change.In the second and third waves，they read either another scientific article，an opinion article that was skeptical of climate science，or an article on an unrelated subjeet.In the fourth wave，the participants simply were asked their beliefs about the science of climate change and their policy attitudes.
   To rate participants' scientific understanding.the researchers asked after each wave if they believed that climate change is happening and has a human cause.To measure their attitudes，researchers asked participants if they favored government action on climate change and if they favored renewable energy.
   "What we found suggests that people need to hear the same accurate messages about climate change again and again.If they only hear it once，it recedes very quickly，" Wood said.It was significant that accurate reporting had positive effects on all groups，including those who originally rejected climate change.But it was even more encouraging that it affected attitudes.

（1）What does the underlined word "recedes" in paragraph 2 mean？
A．Increases.
B．Graduates.
C．Disappears.
D．Strikes.
（2）What does paragraph 4 mainly tell us？
A．The research object.
B．The research result.
C．The research purpose.
D．The research procedure.
（3）Why did researchers ask participants the second question？
A．To survey the government's satisfaction rate.
B．To make an assessment on their attitudes.
C．To teach them scientific understanding.
D．To measure action on climate change.
（4）What can be the best title for the text？
A．Science Report Of Climate Change Can Affect Minds
B．Online Participants Joined In A Four-Wave Experiment
C．Accurate Science Reporting Don't Persuade Only Politicians
D．People Should Hear Accurate Messages About Climate Change

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.
