203748. （2024•西工大附中•高二上期末）     A key part of starting to exercise is choosing when to work out.Morning，afternoon，or evening：Which time is best？Scientists have studied this dilemma extensively.
    For beginners，morning workouts are often the most frightening.Trading a cozy，nurturing bed for an unpleasant，unforgiving fitness center can be a rude awakening to say the least.But morning workouts have their advantages.Challenging the body triggers the release of endorphins（内啡肽），which can make you more productive and attentive at work.Moreover，for those who struggle to fall asleep at night，habitual morning exercise may help to reset their circadian rhythms，the internal，biological processes that regulate the24-hour sleep-wake cycle.
    But early exercisers may not be able to achieve peak performance.Stiffer muscles，fewer stored energy reserves from overnight fasting，and a.slightly cooler body temperature in the morning add up to disturb exercise output.Therefore，more enthusiastic exercisers might prefer working out in the afternoon.A small，12-week study focusing on pre-diabetic and diabetic men found that afternoon training produced slightly more beneficial metabolic（新陈代谢的）effects and resulted in a little more fat loss compared to morning training.
    Finally，some folks may decide to work out later in the evening.Studies centered around this time of day tend to focus on whether or not nightly exercise negatively impacts sleep quality.Gathered research suggests it does not and，instead，actually improves sleep.However，intense exercise performed within an hour of one's bedtime absolutely will make it more difficult to fall asleep.For this reason，most exercise experts recommend at least 90 minutes of downtime between the conclusion of an exercise session and attempting to fall asleep.
    Whether morning，afternoon，or evening，it is optimal（最佳的）if exercise timing remains somewhat consistent，research has found.For example，a competitive marathon runner will exhibit the best performance when his/her exercise training sessions occur at the same time-of-day as the marathon.Still，it is perfectly fine to mix up your workout times to fit with your schedule.The average person need not worry over when to work out just because of some slight bodily differences based on time-of-day.Regular exercises，after all，perhaps the single best thing that humans can do for their health，and ideally，it should serve as stress relief rather than something to stress over.

（1）Which of the following can benefit a man with sleeping disorder？
A.Sleeping immediately after workouts.
B.Regular workouts between 7 a.m.and 10 a.m..
C.Reducing the exercise time by at least 90 minutes.
D.Exercise between 2 p.m.and 5 p.m..
（2）Which of the following is right for diabetic men？
A.It is hard to lose weight in the morning.
B.Morning exercise produces harmful metabolic effects.
C.Diabetic men are easy to lose more fat.
D.Exercise may be more efficient in the afternoon.
（3）What can be inferred from the last paragraph？
A.The average person varies slightly in body.
B.A marathon runner will perform best in the training.
C.It's good to exercise at the same time every day.
D.It is fine to exercise ahead of schedule.
（4）Which one is the most suitable title？
A.Exercise：A dilemma
B.AM or PM：When is the best time to exercise？
C.Exercise timing should remain：consistent

201988. （2023•新城区•二模） Childhood obesity（肥胖）isn't only caused by over eating.A lot of environmental and lifestyle variables—such as skipping breakfast，irregular sleeping patterns and less sleep time—also contribute towards this disturbing trend，says a new study.
   According to the study conducted by University College London's researchers，children who skip breakfast and sleep less are more likely to have bigger appetites and tend to consume more energy-rich foods throughout the day，leading to excessive weight gain.The team also found that smoking habit of mothers during pregnancy（怀孕）is also one of the contributory factors for a child being overweight.
   Interestingly，these results challenge the conventional belief that over-eating is main cause of increasing obesity rates among children.In addition，factors like watching too much television，consuming sugary drinks，eating fruits and introducing solid food sooner don't certainly lead to childhood obesity.
   The researchers used data from a multi-disciplinary research project that tracks the lives：of children from 19，244 families across the UK，born from September 2020 to January.2021.After analyzing the data，they found that in UK，83.3%of new babies had non-overweight and stable.BMI （身体质量指数）.Only 1% had a mildly increasing BMI，while another 2.5% tended to have a sharply increasing BMI.However，due to poor lifestyle choices and environmental factors，6% of the children were already overweight when they were three years old.
   The study authors concluded that modifying（更改） a child's environment early in life can go a long way in reducing their chances of gaining abnormal weight，which can also affect their health in later years.
   The researchers recommended that dealing with the childhood obesity calls for a mixture of preventive actions，for example，creating awareness among the families around the benefits of a healthy lifestyle and also instructing and supporting parents throughout the pregnancy，and even before and after it.

（1）What is paragraph 2 mainly about？
A．The effect of childhood obesity.
B．The irregular lifestyle of children.
C．The new trend of social development.
D．The causes of children being overweight.
（2）What do people usually think leads to childhood obesity？
A．Sleeping less and skipping breakfast.
B．Watching too much TV and playing games.
C．Smoking and introducing solid food sooner.
D．Consuming too much food and sugary drinks.
（3）What can we know from the data of the research in UK？
A．The obesity rates among children were not high.
B．Most of the children didn't get energy-rich foods.
C．The irregular lifestyle had little effect on children.
D．The study result was beyond researchers' expectation.
（4）What suggestion do the researchers offer parents？
A．Improving the living environment.
B．Protecting children from any harm.
C．Increasing their physical activity.
D．Raising awareness of healthy lifestyle.

201617. （2025•临潼区•二模）     Americans' waistlines have grown relentlessly for decades：a costly，debilitating and deadly trend that prompted observers to wonder if and when they would finally stop expanding.Well，the federal government released data Sept.24 showing that the obesity epidemic，one of the most terrible public health crises，might have stopped worsening.And there is the reason to imagine the numbers will get better from here.
    Obesity has been linked to asthma，heart disease，stroke，Type 2 diabetes，some cancers and severe outcomes from respiratory（呼吸的） illnesses.The latest National Health and Nutrition Examination Survey，which interviewed nearly 6，000 individuals between August 2021 and August 2023，showed that the epidemic of obesity among adults was 40.3 percent -down from 41.9 percent in the previous survey，conducted between 2017 and 2020.It is the first such decline in more that a decade，and it could mean that，at long last，"obesity epidemic is potentially balancing in the United States，"as a Centers for Disease Control and Prevention official told us.
    Multiple caveats（警告） apply.Even if it has plateaued，the obesity rate is still far too high，having more than tripled since the early 1960s，when it stood at 13 percent；a decade ago，in 2013-2014，it was 37.7 percent.The CDC report indicates that the"severe"obesity rate is up from 7.7 percent a decade ago to 9.7 percent in the latest survey.The statistical tool CDC uses to define obesity，body mass index（BMI），which measures neither body fat nor its distribution within a given individual.And as of yet，there is no precise explanation for the encouraging new data.Factors such as genes，certain medications，sleep quality，gut fauna，stress，nutrition and access to health care all affect obesity.
    In a 2023 study，scientists at the National Kapodistrian University in Athens hypothesized（假设）that obesity might be peaking worldwide because it has reached"a biological limit".That is，nearly all the people genetically susceptible（易受影响的） to obesity are obese already.Another possibility：production of highly processed foods has maxed out relative to the world's ability to consume it.Also，public health campaigns might have had their intended effects：increased awareness，promoting healthier food choices and more opportunities for physical activity.
    The decline in the obesity rate was not quite as dramatic as the one in teen vaping（电子烟）；the data might not even suggest a permanent plateau in obesity rates.Still，the numbers give reason for hope-and more hard work.

（1）What's the main idea of the first paragraph？
A.There are less fat people than ever before.
B.There are more fat people than ever before.
C.Americans are worried about their waistlines.
D.Americans don't know when they will be thin.
（2）What can be known from the passage？
A.The obesity rate is not so high any more according to the recent survey.
B.Obesity will not exist in the United States according to the recent survey.
C.Obesity epidemic decreases a little within twenty years for the first time.
D.BMI measures both body fat and its distribution within a given individual.
（3）What does the underlined word"plateaued"in the third paragraph mean？
A.Reached the peak.
B.Reached the balance.
C.Reached the bottom.
D.Reached the standard.
（4）In which column of the newspaper can we read the passage？
A.Culture.
B.Biography.
C.Literature.
D.Health.

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

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

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

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

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

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

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

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

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

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.

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？        ?

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.

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.

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

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