203937. （2024•鄠邑二中•高一下期末）     The vast majority of Spain's trains will be free until the end of the year in a new program.People visiting the West European country can now whizz （飞速行驶） across it in the relative luxury of one of its trains for zero cost.As well as being much better for the environment than air travel，sitting on a train and watching the countryside slip by is the perfect way to get to know a country.
    Under Spain's new program，all short and medium train rides are free—with the right ticket—providing the perfect opportunity to see Catalonia，Andalucia and the Basque Country.Tourists can take advantage of the discounts，which have been brought in to help the population deal with the cost of living crisis，if they buy multi-journey tickets. "I'd like the people of Spain to know that I'm fully aware of the daily difficulties that most people have，" a senior official said. "I know salaries cover less and less and that it's difficult to get to the end of the month." The country's Ministry of Transport said the measure would help people get to work safely as fuel prices continue to rise sharply.
    Spain joins Germany in cutting the price of public transport，with the latter country launching a ticket costing €9 which gives a full month of travel from June until the end of August.Austria has started offering a climate ticket，which allows people to complete journeys for just €3.When it was first launched last year，the popularity of the ticket almost caused its website to crash.The UK government has not announced any plans to encourage the use of trains，despite the seriousness of the climate crisis and the damage petrol and diesel cars cause.Instead，the government cut fuel duty by 5% in March for 12 months，encouraging more people to get behind the wheel.

（1）What can be inferred about the program？
A.People still have doubt about it.
B.It is of benefit to the environment.
C.The trains in Spain are completely free now.
D.Spain is the only country in Europe to cut transport costs.
（2）What is the main purpose of introducing the program？
A.To lower fuel prices.
B.To relieve the stress of airline business.
C.To promote tourism and benefit people of Spain.
D.To show the government's concern for the public.
（3）What does the author think of the UK government's practice？
A.Unwise.
B.Admiring.
C.Perfect.
D.Praiseworthy.
（4）What is the main idea of the last paragraph？
A.The practices on public transport in some countries.
B.The economic benefits of the program.
C.The program's great benefits to health.
D.The popularity of the climate ticket.

204163. （2023•周至四中•高二下期末） Fairy Tale-Like Destinations You Can See in Real Life Zhangjiajie National Forest Park （China）
    Zhangjiajie National Forest Park is part of the larger protected Wulingyuan Scenic Area in China's Hunan province.The 3，000 towering sandstone pillars in this huge park are breathtaking.Some are more than 600 feet tall，and most have vegetation growing on their sides and summits.
    The Chocolate Hills（Philippines）
    There are around 1，776 hills covering a 20-square-mile area in the towns of Carmen，Batuan，and Sagbayan，each with a seemingly perfect conical shape.The hills range from 100 feet to almost 400 feet in height.The most widely accepted theory of their origin is that they consist of coral deposits（珊瑚沉积物） that were forced upward due to rainwater and erosion.
    Much of the year，the hills are covered with green grass，which increases their charming appearance.However，during the dry season，the grass turns deep brown，giving them their "chocolate"tag.
    Deadvlei（Namibia）
    Deadvlei，also spelled Dead Vlei，is a plain surrounded by red sand dunes in the Namib Desert.The site is so unique because trees once grew there，but shifting dunes and climate change killed the vegetation over time.The air was so dry that the trees never rotted，thus becoming skeletons.But they are not scary.These rare trees are estimated to be around 900 years old.The combination of tall red dunes，bright clay flats，and tree skeletons combine to create a fantastic atmosphere that inspires tourists to visit.
    Lake Hillier（Australia）
    Lake Hillier sits on Middle Island off the coast of Western Australia.Hillier is a small lake，less than 2，000 feet in length，but it grabs people's attention because of its incredible bright pink color.It is especially noticeable because it contrasts with the neighboring blue ocean and the surrounding green leaves.
    Why the lake is pink is not 100%clear，but the theory is that it's caused by the interaction between the salty water and a specific type of micro algae （微藻类） that grows well under these specific conditions.

（1）Of the following destinations，whose popularity is least related to color？
A．Deadvlei.
B．Lake Hillier.
C．The Chocolate Hills.
D．Zhangjiajie National Forest Park.
（2）What made tree skeletons in Deadvelei？
A．The sand dunes.
B．The dry air.
C．The clay flats.
D．The salty soil.
（3）What is the purpose of the text？
A．To analyze the formation of some scenic spots.
B．To explain the roles of color in fairy tales.
C．To introduce some fascinating scenic areas.
D．To show the ways of visiting exceptional destinations.

204222. （2023•长安区一中•高二下期末）     A promotion （促销活动） offering 98 yuan domestic plane tickets is being advertised by Chinese online travel platform LY.COM.While such a low price sounds amazing，there is just one catch： the purchaser is not told where the flight is heading，nor when it will take off.
   The promotion has become a trending topic on Chinese social media as some people have been attempting to book them ahead of the upcoming May Day holiday.Labeled as a "destination blind box" on the site，tickets are purchased through a rather simple booking procedure，in which passengers provide their travel information，select a departure airport and then pay their 98 yuan.If the randomly chosen date and destination are unsuitable，users may ask for a refund，but once they "lock in" their tickets，there is no going back.
   "Destination blind box" is now a hot topic on China's online platforms. "I believe young people are a big target demographic （特定年龄段人口） for this promotion，because they not only enjoy the thrill of the unknown，but also like to show off their lives through these types of commercial activities.Like this one for instance，it doesn't matter if they finally go or not.Booking a ticket and posting about it on social media can still suggest that one has adventurous and life-loving qualities，" said Fan，a marketing expert who has worked with civil aviation clients.
   Many people not only shared the screenshots of tickets they drew，some even came up with a tutorial to teach the booking procedure under the free cancelling policy.However，some others claimed it is too rare to draw a ticket that is ideal. "If it wants to be a profitable activity，the release of the tickets must have been planned ahead and is not as random as it seems.It will not have popular airlines.The marketing campaign may also be aimed at the fast sale of some tickets from less popular airlines that were originally not that expensive.If they sell a large quantity of tickets，the company may still earn a profit even though the price is 98 yuan，" an expert in tourism suggested.

（1）Which of the following best explains "catch" underlined in paragraph 1？
A．Benefit.
B．Mistake.
C．Disadvantage.
D．Charm.
（2）What is paragraph 2 mainly about？
A．The origin of "destination blind box".
B．The purchase introduction to "destination blind box".
C．The original purpose of "destination blind box".
D．The popularity of "destination blind box".
（3）Why will "destination blind box" appeal to young people according to Fan？
A．It allows them to experience various adventures.
B．It satisfies their desire to travel around China.
C．It helps them save money on the cost of travel.
D．It accords with their lifestyle and attitudes.
（4）In which part of a newspaper can you find this article？
A．Economy.
B．Science.

202150. （2022•西安中学•八模） Plants：we eat them，juice them-and now it seems we can mine them too!
   After a successful experiment on the island of Borneo，the botany professor Alan
   Baker and a group of researchers want to introduce phytomining （harvesting minerals from plants） as a better，partial substitute for traditional mining.
   Phytomining，also known as agromining，means collecting metals from live plants.However，this can only be done with a group of plants known as "hyperaccumulators".There are around 700 identified types worldwide，and what makes these hyperaccumulators special is that they naturally attract and absorb minerals through their roots-metals poisonous to other plants- and then store huge，pure concentrations of these minerals in their bodies.The metals can then be extracted（提取） from the plants' sap（汁；液），oil，or sometimes even live tissue.
   Baker and his colleagues see a lot of potential in phytomining.Not only can it help meet the growing global demand for metals，but is a way of undoing some of that damage to the environment by traditional mining.
   One of the biggest problems with traditional mining is that it pollutes the surrounding area.Phytomining can extract metal waste，plus planting the hyperaccumulators would regrow the deforested areas caused by mining operations.Aside from this，if phytomining is able to replace part of traditional mining，then there would be fewer instances of bad mining practices like abandoned mines，which pollute the nearby waters.Also，since phytomining provides metals that are already naturally pure，there is no need to use huge amounts of energy to purify the ore（矿石）.
   Phytomining has its drawbacks.Harvesting plants on a large scale is expensive today，compared to traditional mining.Besides，plants can be wiped out by diseases or unexpected weather conditions.
   However，there are many reasons to consider phytomining.After all，we need to make sure that our planet can keep up and sustainable practices like phytomining give us the hope that our advancement doesn't mean sacrificing Mother Earth.

（1）What makes hyperaccumulators different from other plants？
A．The sap poisonous to other plants.
B．The oil extracted from live plant tissue.
C．The ability to take in and store minerals.
D．The concentrations of mineral in their bodies.
（2）What is the advantage of phytomining？
A．It uses clean energy to purify the ore.
B．It may reduce the deserted mines.
C．It can't be destroyed by diseases.
D．It can stop deforestation.
（3）What is the author's attitude toward phytomining？
A．Pessimistic.
B．Indifferent.
C．Optimistic.
D．Skeptical.
（4）What is the best title for the text？
A．Metals From Plants.
B．Benefits of Phytomining.
C．The Future of Phytomining.
D．What Are Hyperaccumulators？

202282. （2022•西工大附中•七模） Innovation has pretty much finished with car tires （轮胎） right，I mean，what's left to change？How about the whole "air" part？
   Michelin Company's attempt to tackle tire rubbish around the world witnessed them roll out puncture-proof "airless" tires，which they say should help reduce the 18% of all world tires that are abandoned early due to punctures （轮胎漏气）.Deserted tires are a huge worldwide waste problem—the U.S.produces 260 million abandoned tires per year，many of which end up in landfills or on the sides of the freeway where they release harmful gases and micro-plastic pollutants as they break down.
   Michelin Company's Unique Puncture Proof Tire System or "UPTIS" is designed using 46% recycled material，and made from a plastic matrix （母体） mixed with glass fibers that provide a flexible outer layer with a strong inner one. "The truly distinctive structure of the Michelin UPTIS prototype（原型），or its "strangeness" as we have often heard it called，really attracted the eye of many visitors and left a lasting impression on them，" stated Cyrille Roget，Michelin Group Technical and Scientific Communications Director. "It was an unusual experience for us，and our greatest satisfaction came at the end of the demonstration when our passengers，who were undoubtedly a little alert（警觉）at first，said they felt no difference compared with conventional tires."
   Michelin Company believes airless tires will improve everyone's lives.Maintenance （保养） costs for company's vehicle fleets will be less expensive，and inexperienced car owners won't accidentally ruin their rubbers when driving them because they are over-or under-inflated（充气）.Although they are still in development stage and using at a large scale within years is unlikely to be available，Michelin Company is not in the least doubtful about their tires' future.

（1）Why does the author ask questions in the first paragraph？
A．To explain a strange phenomenon.
B．To clarify a difficult concept.
C．To present a well-known fact.
D．To introduce a new topic.
（2）What is the main idea of the second paragraph？
A．The new tire runs more smoothly.
B．The world greatly needs airless tires.
C．Traditional tires threaten the environment.
D．Michelin Company battles the issue of wasted tires.
（3）What do we know about "UPTIS"？
A．Its structure distances visitors.
B．It only uses recycled materials.
C．It combines plastic and glass fibers.
D．Its comfortableness beats ordinary tires.
（4）What's Michelin Company's attitude towards their new tires？
A．Tolerant.
B．Positive.
C．Mixed.
D．Objective.

204497. （2023•蓝田县•高二下期末） Fast walkers may live longer than dawdlers （缓慢的人）— regardless of their weight，a new study suggests.
    Researchers at Leicester University analyzed data on 474，919 people with an average age of 52 in the UK Biobank between 2006 and 2016.They found women who walked briskly had a life expectancy of 86.7 to 87.8 years old，and men who kept up the pace had a life expectancy of 85.2 to 86.8.Slow walkers hadn't much encouraging prospects （前景）：women had a life expectancy of 72.4，and men of 64.8 years old，if they were more leisurely in their movements.According to the paper，published last week，that ratio held true even if the fast walkers were severely overweight.It does not necessarily mean fast walkers will live longer.Experts say it suggests walking speed could be a simple way for doctors to judge their patients' general health alongside other tests.
   It is hardly the first study holding up walking speed as a powerful evidence that appears to improve and determine our health.
   In 2011，the Journal of the American Medical Association （JAMA） published a study by Stephanie Studenski，who found the same：walking speed was a reliable predictor of life expectancy.
   In 2013，US researchers found walking pace was linked to lower heart disease risk and longer life expectancy.In 2018，a study from the University of Sydney found picking up your walking pace to even an "average speed" could cut your risk of premature death by a fifth.
   And Tom Yates，the physical activity professor at Leicester who's behind the latest study，has been publishing findings on this connection for years.
   In 2017，he analyzed the same UK Biobank data and found walking speed appeared to affect the risk of dying from heart disease — concluding that the slowest walkers were twice as likely to suffer a heart-related death compared to quick walkers.

（1）What does the underlined word "briskly" in paragraph 2 probably mean？
A．Casually.
B．Quickly.
C．Actively.
D．Energetically.
（2）What does the paper published last week show？
A．Most fast walkers are overweight.
B．Fast walkers have a simple way of living.
C．Walking speed can help doctors know about their patients' general health.
D．Doctors will surely have better ways to cure their patients of their illness.
（3）What did US researchers find？
A．Walking slowly is bad for people's health.
B．Walking speed can predict a person's life expectancy.
C．People won't die early by increasing their walking pace.
D．Lower heart disease risk is determined partly by walking pace.
（4）What's the best title for the text？
A．Fast Walkers May Have a Long Life Expectancy
B．Life Expectancy Is Determined by Exercise
C．Researchers Try to Improve Life Expectancy
D．The Public Doubt Researches on Walking Speed

202520. （2021•西安中学•二模） Researchers studied data from the National Health and Nutrition Examination Survey，organized by the Centers for Disease Control and Prevention （CDC） in the United States and looked at the relationship between cups of coffee drunk per day and both total body fat percentage and abdominal or trunk fat.
   They found that women aged 20---40 who drank two or three cups of coffee per day had the lowest level of obesity，3.4% lower than people who did not consume coffee.Among women aged between 45-69，those who drank four or more cups had an obesity percentage 4.1% lower.
   Overall，the average total body fat percentage was 2.8% lower among women of all ages who drank two or three cups of coffee per day.
   The findings were consistent whether the coffee consumed was caffeinated（含咖啡因的）or decaffinated and among smokers/non-smokers and those suffering from chronic diseases（慢性病） when compared to those in good health.
   In men，the relationship was less significant although men aged 20-44 who drank two or three cups per day had 1.3% less total fat and 1.8% less trunk fat than those who didn't consume coffee.
   Around 7 million tons of coffee is consumed globally every year.Dr.Lee Smith，senior author of the study，said： "Our research suggests that there may be active compounds in coffee other than caffeine that manage weight and which could potentially be used as anti-obesity compounds."
   "It could be possible that coffee，or its effective ingredients could be integrated into a healthy diet strategy to reduce the burden of chronic conditions related to the obesity，" Dr.Lee Smith added. "It's important to interpret the findings of this study in light of its limitations - the study was at a specific point in time so trends cannot be established.However，we don't believe that someone's weight is likely to influence their coffee consumption."

（1）What can be inferred from the text？
A．Coffee has less effect on men than women in fat according to the findings.
B．The women aged 20-44 like to drink two or three cups of coffee per day.
C．The researchers found that the coffee consumers preferred caffeinated coffee.
D．Trends will be established to limit people's weight by their coffee consumption.
（2）What in coffee mainly influences body fat according to Dr.Lee Smith？
A．The caffeine.
B．The decaffeinated.
C．The effective compounds.
D．The rich nutrition.
（3）What might the study be used for？
A．Developing a new coffee.
B．The treatment of obesity.
C．The treatment of heart disease.
D．The study of physical differences between the sexes.
（4）Where is this text most likely from？

202501. （2021•西安中学•一模） Free school meals are back in the news.Footballer Marcus Rashford's petition（请愿书） to extend free school meals provision （供给） into the school holidays has collected 1.1 million signatures，causing the government to reverse policy.It has restarted the debate over free school meals，fuelled，most recently，by figures forecasting that if the government ends as planned the current ￡20 top-up（附加款），another 200，000 children will slip into poverty.This is in addition to the 550，000 children already living in poverty previous to COVID-19.
   The roots of the current school meals system lie in the mid-19th century.In Manchester，independent charities as well as official bodies started to provide free meals for undernourished children in the 1870s.When education became compulsory in the following decades，the extent of the issue became apparent.Proponents of feeding starving children pointed out that it was due to government order that children were in school，not working and contributing to the family food budget，so the government should pay.
   Reception was mixed.Then，as now，children rejected foods they weren't used to.Diaries of the time talked of "little bags of mystery" （sausages）.Some children were put off brassicas （芥菜类） for life.Finding the balance between cheap and good proved hard.The chief medical officer talked about the lack in calorie value and elements of a well-balanced diet which a needy child does not get at home，such as milk，cheese，eggs，green vegetables，fruit and meat.In 1980，the Tory government，desperate to cut costs，made provision largely optional and abolished nutritional standards.Over the next 15 years convenience and cost became the most important.
   Today，school meals provision is linked to benefits：in England around 17 percent of children are entitled to free school meals.Provision is outsourced （外包），leading to huge variation.In the last year，we've seen all of the age-old debates repeated once more.How do we decide who is entitled？How do we guarantee quality？Who decides what children eat？Who pays？Undernutrition does not just have physical effects，but also affects behavior and ability to learn.It has a lifelong impact.The arguments around free school meals seem never to end.But they are hugely important and，until poverty is ended，they will not and should not go away.

（1）Why did Marcus Rashford start the petition？
A．To feed an increasing number of children in poverty.
B．To restart the debate over free school meals.
C．To raise fund for hunger relief for children.
D．To lift children out of poverty.
（2）What does the paragraph 2 probably talk about？
A．Manchester and independent charities set up school free meals.
B．It was government that should pay for the school meals.
C．How did the current school meals system come into existence？
D．It was compulsory education that contributed to free school meals.
（3）What can we infer about school meals from paragraph 3？
A．Some children liked brassicas provided in the school.
B．School meals were both tasty and cheap.
C．School meals failed to meet children's nutritional needs.
D．The Tory government chose nutrition over cost.
（4）What does the writer think of the debates over free school meals？
A．Never-ending.
B．Meaningless.
C．Influential.
D．Necessary.

204904. （2022•雁塔二中•高二下期末） 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（因素）.
   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 McIntyre，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，McIntyre 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，McIntyre 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.

202388. （2021•西安中学•十模） Researchers at the University of Maryland have turned ordinary sheets of wood into transparent material that is nearly as clear as glass，but stronger and with better insulating properties（隔热性）.It could become an energy efficient building material in the future.
   Wood is made of two basic ingredients：cellulose，which are tiny fibres，and lignin （木质素），which is a glue-like material that bonds the fibres together to give it strength.The lignin also contains molecules called chromophores，which give the wood its brown color and prevent light from passing through.
   Early attempts to make transparent wood involved removing the lignin，but this involved harmful chemicals，high temperatures and a lot of time，making the product expensive and somewhat fragile.The new technique is so cheap and easy that it could literally be done in a backyard.
   Starting with pieces of wood a meter long and one millimeter thick，the scientists simply brushed on a solution（溶液）of hydrogen peroxide using an ordinary paint brush.When left in the sun，or under a UV lamp for an hour or so，the peroxide remove color from the brown chromophores but left the lignin undamaged，so the wood turned white.Next，they filled the wood with a tough transparent epoxy，which filled in the spaces in the wood and then hardened.This made the white wood transparent.
   As window material，it would be much more resistant to accidental breakage.The clear wood is lighter than glass，with better insulating properties，which is important because windows are a major source of heat loss in buildings.It also might take less energy to produce clear wood because there are no high temperatures involved.
   Transparent wood could become an alternative to glass in energy efficient buildings，or perhaps coverings for solar panels in harsh environments.There could be no end of uses.

（1）What is the second paragraph mainly about？
A．The classification of wood strength.
B．The characteristics of wood.
C．The causes of wood color.
D．The structure of wood.
（2）How did the researchers make wood transparent in the past？
A．By removing the lignin.
B．By reducing chemicals.
C．By lowering the temperature.
D．By changing the experiment site.
（3）What is the function of the epoxy？
A．To make the wood stronger.
B．To take away the brown color.
C．To turn the wood transparent.
D．To fill the spaces in the wood.
（4）Which can be a suitable title for the text？
A．Replacing Glass with Wood
B．Turning Wood Transparent
C．Energy Saving Material

202368. （2021•西安中学•四模） Sure，chocolate is a delicious treat，and it's a staple of some of our favorite desserts.But it's not a health food，so it should be enjoyed in moderation-right？
   Well，it turns out that eating chocolate might actually have a pretty significant health benefit.According to research conducted by five scientists in Italy，compounds found in chocolate，called flavanols，can help boost cognitive （认知的） performance.Yup，chocolate's good for your brain.
   The scientists，studying at the Universities of Rome and L'Aquila，summarized research from ten different studies.The studies assessed people's performance on cognitive tests before and after eating cocoa or chocolate.The results were pretty telling：in nine out of the ten studies，there was a noticeable improvement after the subjects had eaten the chocolate.The scientists found improvements in "general cognition，attention，processing speed and working memory." Sounds pretty good to us!
   And that's not all.In subjects，especially women，who performed the tests while sleep-deprived，the flavanols helped relieve the negative effects of the sleep deprivation.And there's even more good news.The researchers also found that eating chocolate daily （over periods ranging from five days to three months） produced noticeable long-term improvements in cognition.Older adults，whose memories were already declining，saw an especially significant improvement.
   All chocolate has flavanols，since they occur naturally in cocoa.However，dark chocolate lovers feel happy，because it has more flavanols than any other type of chocolate.In fact，the scientists themselves have claimed that，after doing this research，they've started eating dark chocolate every day!
   Now，we're not saying you should start eating chocolate for breakfast，lunch and dinner - it's still high in sugar and low in nutrients.But next time you find yourself yawning after a sleepless night，snack on some chocolate and let the flavanols work their magic.

（1）What does the underlined phrase in Paragraph 1 probably mean？
A．As much as possible.
B．For three meals.
C．In right amount.
D．Not in the least
（2）How does a student perform while learning after eating chocolate？
A．He memorizes less than before.
B．He can't concentrate on lessons in the slightest.
C．He becomes more excited.
D．He understands what the teacher says faster.
（3）According to the passage，if your memory fails，what should you do？
A．Eat chocolate as three meals.
B．Use chocolate as a daily snack.
C．Hunt for dark chocolate.
D．Ask a doctor for advice.
（4）What's the main idea of the passage？
A．Chocolate is a beneficial but unhealthy food.
B．Eating chocolate benefits our learning.
C．Eating chocolate works on your sleep.
D．Chocolate contains low nutrients.

204942. （2022•阎良区•高二下期末） Alcohol was the leading risk factor for disease and premature death in men and women between the ages of 15 and 49 worldwide in 2016，accounting for nearly one in ten deaths，according to a study published in The Lancet in 2018. "It has been known for decades that heavy drinking is bad for brain health，" said Sadie Boniface，head of research at the UK's Institute of Alcohol Studies.While there is no such thing as a "safe" level of drinking，with increased consumption of alcohol associated with poorer brain health，according to a recent study.
   In the observational study，researchers from the University of Oxford studied the relationship between the self-reported alcohol intake of some 25，000 people in the UK，and their brain scans.The researchers noted that drinking had an effect on the brain's gray matter—regions in the brain that make up "important bits where information is processed，" according to lead author Anya Topiwala，a senior clinical researcher at Oxford.
   "The more people drank，the less the volume of their gray matter，" Topiwala said via email. "Brain volume reduces with age and more severely with dementia （痴呆）.Smaller brain volume also predicts worse performance on memory testing，" she explained. "While alcohol only made a small contribution to this （0.8%），it was a greater contribution than other 'changeable' risk factors，" she said，explaining that changeable risk factors are "ones you can do something about，in contrast to aging."
   The team also investigated whether certain drinking patterns，beverage types and other health conditions made a difference to the impact of alcohol on brain health.They found that there was no "safe" level of drinking—meaning that consuming any amount of alcohol was worse than not drinking it.They also found no evidence that the type of drink—such as wine，spirits or beer—affected the harm done to the brain.
   However，certain characteristics，such as high blood pressure or obesity，could put people at higher risk，researchers added.So we shouldn't forget alcohol affects all parts of the body and there are multiple health risks.

（1）How was the observational study developed？
A．By comparing brain and health.
B．By comparing people and the researchers.
C．By comparing information and gray matter.
D．By comparing alcohol intake and brain scans.
（2）What is the result of the research？
A．Drinking wine have no impact on brain.
B．Drinking spirits have more impact on brain.
C．Drinking alcohol can cause reducing of brain volume.
D．Drinking alcohol can lead to obesity.
（3）Which of the following groups has a higher risk when drinking alcohol？
A．People drinking more types.
B．People with high blood pressure.
C．People selling the wine.
D．People with diabetes.
（4）What can be the best title for the passage？
A．Stay Away From Alcohol.
B．Lack of Sleep.
C．Consumer Health.
D．Keep-fit Exercise.

204422. （2023•铁一中学•高二上期末） As the climate warms，birds are shrinking and their wingspans are growing，according to a new study.Researchers analyzed 70，716 birds from 52 kinds of North American migratory（迁徙的）bird species collected over 40 years.The authors say the study is the largest of its kind and that the findings are important to understanding how animals will adapt to climate change.
   "We found almost all of the species were getting smaller." said lead author Brian Weeks，an assistant professor at the University of Michigan.
   "The species were pretty diverse，but responding in a similar wav." he said. "The consistency waocking."
   He said studies of animal responses to climate change often focus on shifts in geographical range or timing of life events，like migration and birth.But this study suggests body morphology（形态）is a crucial third aspect.
   "That's one major implication，" he said， "It's hard to understand how birds will adapt without taking all three of these things into consideration."
   The findingowed that from 1978 to 2016，the length of the birds' lower leg bone shortened by 2.4%.Over the same time，the wings lengthened by 1.3%.
   The evidence suggests warming temperatures caused the decrease in body size，which in turn caused the increase in wing length.
   "Migration is an incredibly taxing thing they do，" Mr.Weeks said，explaining that the smaller body size means less energy available for the birds to complete their long journeys.
   He says the birds most likely to survive migration were the ones with longer wingspans and smaller bodies.
   The scientists aren't exactly sure why warmer temperatures cause birds to shrink.One theory is that smaller animals are better at cooling off，losing body heat more quickly.

（1）What's the best title for the text？
A．All of the Birds Are Getting Smaller
B．Animals Are Adapting to Climate Change
C．Climate Change Is Causing Birds to Shrink
D．Scientists Are Finding Causes of Warm Climate
（2）What made Brian Weeks feel astonished？
A．It took 40 years to collect 70，716 birds from North America.
B．Many birds are shrinking when responding to the climate change.
C．All migratory bird species were collected to do the important research.
D．So many researchers take part in the largest study to work out the findings.
（3）What does the underlined word "taxing" most probably mean？
A．Tiring.
B．Important
C．Easy.
D．Pleasant
（4）What can we infer from the last paragraph？
A．The migratory birds aren't big.
B．The temperatures will be higher.
C．The scientists will go on further study.
D．The smaller animals will surely live longer.

204961. （2022•阎良区•高二上期末） What makes a human being？Is it our thoughts？Our emotions？Our behavior？All of these things make us who we are，but at the center of the matter is the genome（基因组）-the genes inside our bodies that may determine everything from our hair colour to our intelligence.But if we could change our genome，what would it mean to us？
   In an online video posted on Nov 26，He Jiankui，a biological researcher from Southern University of Science and Technology in China，said that he had helped to make the world's first genetically edited babies.
   These are twin girls，born in November，with genes edited in an attempt to help them fight against possible future infection with the AIDS virus.
   He said that he chose to do this because HIV infections are a big problem in China. "I feel such a strong responsibility that it's not just to make a first，but also to set an example，" he told the Associated Press（AP）.
   The announcement has caused an international storm.Some believe that success will benefit the families of HIV patients.Considering that HIV is "a major and growing public health threat，" attempted gene editing for HIV is justifiable，Harvard Medical School genetics professor George Church told AP.
   However，others think that gene editing technology is still unsafe to attempt.
   "Gene editing itself is experimental and is still associated with unexpected mutations（突变），causing genetic problems early and later in life，including the development of cancer，" Julian Savuleseu，a specialist in ethics at the University of Oxford，told BBC News.
   Others fear that this could open the door to using gene editing technology to make designer babies.It might give the parents the choices to choose everything from their baby's eye color to intelligence.
   "You could find wealthy parents buying the latest upgrades for their children，leading to even greater inequality than we already live with，" Marcy Darnovsky，director of the San Francisco Center for Genetics，told BBC News.

（1）Why did He Jiankui make the genetically edited babies？
A．Because he wanted to be a leader in gene editing technology.
B．Because he tried to do his part in fighting against HIV infection.
C．Because he attempted to help the twin girls who were infected with AIDS.
D．Because he wanted to become the first to make the genetically edited babies in the world.
（2）What does the underlined word "justifiable" in Paragraph 5 probably mean？
A．Absurd.
B．Hopeless.
C．Skilful.
D．Acceptable.
（3）For those who are against gene editing technology，their reasons are as follows EXCEPT        .
A．Gene editing can determine everything inside a person's body
B．Gene editing may widen the gap between the rich and the poor
C．Gene editing may enable wealthy parents to design their babies
D．Gene editing can cause genetic problems sooner or later in life
（4）Which of the following might be the best title of the passage？
A．Gene Editing：The Genie in the Bottle.
B．Gene Editing：The Way We Should Go.
C．Gene Editing：Hope or Fear for Human Beings.
D．Gene Editing：A Great Success in Human History.
