204555. （2023•鄠邑区•高一上期末） Pet lovers were very angry．Last May，a news article online said three states had passed laws limiting the number of pets that each household could have to only two．The news spread quickly，as many people shared the article on Facebook and other social media sites．But pet owners had nothing to worry about----the article was made-up．
   Many fake （虚假的） news are harmless，but others might have played a role in real-world events．When it comes to online news，even adults can have a hard time telling fact from fiction．
   Education experts say kidould start learning how to tell the difference．
   Of course，there are plenty of reputable websites you can visit to read the news．Well-known news organizations，such as The New York Times and the Associated Press，have their own sites．
   But many other online "news" sources aren't always reliable．And many students have trouble finding out when articles aren't entirely true or are trying to persuade them to think in a certain way．
   Why would someone purposely publish an article that isn't true？The most common reason is to make money．Websites are paid by the companies that post ads on them．Companies want to place their ads on sites that get a lot of visitors．So people create fake news with attention-catching headlines to try to get users to click on them．
   Some of the biggest websites are trying to stop the flow of fake news．Last November，Facebook and Google banned fake news sites from advertising on their pages．Facebook is also working with fact-checking organizations to identify and flag fake articles．But experts say the best way to slow the spread of fake news is for people to be more skeptical（'怀疑的） of what they read online．

A．To make readers focus on fake news．
B．To introduce the topic about fake news．

A．People create fake news to make money．
B．The growing trend of fake news raises concerns．

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.

202635. （2020•西安中学•四模） In the early days of sea travel，seamen on long voyages lived exclusively on salted meat and biscuits．Many of them died of scurvy （坏血病），a disease of the blood which causes swollen gums （牙龈），livid white spots on the flesh and general exhaustion．On one occasion，in 1535，an English ship arrived in Newfoundland with its crew desperately ill．The men's lives were saved by Iroquois Indians who gave them vegetable leaves to eat．Gradually it came to be realized that scurvy was caused by some lack in the sailors' diet and Captain Cook，on his long voyages of discovery to Australia and New Zealand，established the fact that scurvy could be prevented by the supply of fresh fruit for the sailors．
   Nowadays it is understood that a diet which contains nothing harmful may yet result in serious disease if certain important elements are missing．These elements are called "vitamins"．Quite a number of such substances are known and they are given letters to identify them，A，B，C，D，and so on．Different diseases are associated with shortages of particular vitamins．Even a slight lack of Vitamin C，for example，the vitamin most plentiful in fresh fruit and vegetables，is thought to increase significantly our susceptibility （敏感度） to colds and influenza．
   The vitamins necessary for a healthy body are normally supplied by a good mixed diet，including a variety of fruit and green vegetables．It is only when people try to live on a very restricted diet，say during extended periods of religious fasting （斋戒），or when trying to lose weight，that it is necessary to make special supply to make up for the missing vitamins．

（1）Scurvy is a disease that is caused by       ．
A．salted meat and biscuits
B．exhaustion
C．lack of some essential substances
D．need of fresh vegetables and fruits
（2）To avoid such disease as scurvy，it's better for us       ．
A．not to eat much salted meat
B．to supply our diet with various vitamin pills
C．to have more fresh fruit and vegetables
D．to develop a good dietary habit
（3）Based on the passage we can safely conclude that if our diet is not comprehensive enough，       ．
A．vitamin pills are of no use
B．nutritious food might be unhealthy
C．vegetable leaves can be a good treatment
D．religious fasting may help out a lot
（4）Which of the following sentences best expresses the main idea of the passage？
A．Shortages of Vitamin C may cause serious diseases．
B．Fresh fruit and green vegetables contain enough nutrition that is necessary for a healthy body．
C．Vitamins play a vitally important role in people's health．

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

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.

（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 McIntyre？
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 McIntyre：Grow More Big Trees in California

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.

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.

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.

204981. （2022•铁路中学•高二上期末） A device that stops drivers from falling asleep at the wheel is about to undergo testing at Department of Transport laboratories and could go on sale within 12 months.
   The system，called Driver Alert，aims to reduce deadly road accidents by 20%-40% that are caused by tiredness.Airline pilots can also use it to reduce the 30% of all pilot-error accidents that are related to fatigue.
   Driver Alert is based on a computerized wristband（腕带）.The device，worn by drivers or pilots gives out a sound about every four minutes during a car journey.After each sound the driver must respond by squeezing the steering wheel（方向盘）.A sensor in the wristband detects this pressing action and measures the time between the sound and the driver's response.
   Tiredness is directly related to a driver's response time.Usually，a watchful driver would use about 400 milliseconds to respond，but once that falls to more than 500 milliseconds，it suggests that the driver is getting sleepy.
   In such cases the device gives out more regular and louder sounds，showing that the driver should open a window or stop for a rest.If the driver's response continues to slow down，the sounds become more frequent until a nonstop alarm warns that the driver must stop as soon as possible.
   The device has been delivered to the department's laboratories for testing.If these tests，scheduled for six months' time，are successful，the makers will bring the product to market within about a year.

（1）Driver Alert is a device that can         .
A．keep drivers asleep
B．change drivers' response accuracy
C．reduce the possibility of accidents
D．protect drivers when accidents happen
（2）What does the underlined word "fatigue" in Paragraph 2 mean？
A．Illness.
B．Tiredness.
C．Carelessness.
D．Impoliteness.
（3）How does Driver Alert work？
A．By being used as a nonstop alarm all the time.
B．By squeezing the steering wheel on the way.
C．By reminding or warning drivers if necessary.
D．By being worn on drivers' hands every moment.
（4）What do we know about Driver Alert？
A．It must be fixed on the driver's cars.
B．It aims to prevent drivers from sleeping.
C．It has gone through testing at laboratories.
D．It isn't available to drivers at the moment.

205003. （2022•临潼区•高一下期末） Standing in my office 25 years ago was an unknown young astronomer with a half-smile on her face.She had come with an impossible request that my team modify（修改）our thoroughly tested software to make one of our most important scientific instruments do something it had never been designed for and risk breaking it.All to carry out an experiment that was basically a waste of time and couldn't be done—prove that a massive black hole lay at the center of our Milky Way.
   My initial "no way" gradually gave way in the face of her cheerful but firm determination.Andrea Ghez，one of three winners of this year's Nobel Prize in Physics，impressed me with her work on providing solid evidence of a supermassive black hole with the mass of four million suns living at the center of the Milky Way galaxy.
   That determination and the willingness to take calculated risks has always characterized Andrea.For 25 yeare has focused almost completely on Sagittarius A-the name of our own local supermassive black hole.It is remarkable that an entire field of study has grown up in the quarter century，of searching for and finding evidence of these monsters thought to lie at the heart of every large galaxy.
   Andrea did her work at the W.M.Keck Observatory's（天文台）twin telescopes on Maunakea，Hawaii，in the calm and clear air almost 14000 feet above the Pacific Ocean.She started using the very first instrument fixed on Keck Observatory's Near Infrared Camera（NIRC），now gracing the lobby（大厅）at our headquarters.
   Andrea is fond of pointing out that one of the reasons for her success has been this tight and rapid loop（循环）between the needs of the astronomers and the engineers who responded to the challenge.
   This is my friend and longtime colleague，the one who refused to take "no" for an answer：Andrea Ghez，winner of the 2020 Nobel Prize in Physics.

（1）Which words best describe Andrea Ghez？
A．Confident and adaptable.
B．Determined and creative.
C．Brave and kind.
D．Cooperative and generous.
（2）What is the passage mainly about？
A．The Noble Prize for physics.
B．How Andrea won the Nobel.
C．Friendship between colleagues.
D．What makes Andrea different.
（3）What does the underlined word "gracing" in Paragraph 4 mean？
A．Bringing honour to.
B．Being kind enough to attend.
C．Moving in a smooth way.
D．Advancing the level.
（4）From which is the text probably taken？
A．A research paper.
B．A science fiction.
C．A website about scientists.
D．A fashion magazine.

205004. （2022•临潼区•高一下期末） The first great agricultural revolution happened 10，000 years ago，when humans settled on farms.The second was the "green revolution" from the 1930s to the 1960s，in which advances in fertilization，mechanization，and irrigation dramatically increased global food production.The third is likely to come from information，as digital technology and big data help farmers make better decisions and drive up crop production.
   Michael Stern，president and chief executive officer of Climate Corp.，said that the ability to gather detailed information about farmers' fields，coupled with advances in weather forecasting，computing power，and artificial intelligence，will change farming from a business that often reacts to the past—applying insecticide this year because of a disease outbreak last year—to one that uses real-time data and weather forecasts to make more accurate decisions for the season to come.
   Over the course of a growing season，farmers make 40 to 50 key decisions that affect crop performance.Recent trends that have swept other areas of society—such as cheap data storage，the ability to transfer data witlessly，and dramatic increases in computing power—have the potential to transform the farm.
   Stem offered the example of a farmer preparing for the regular fall fertilizing of his fields who delays the application after being informed of a coming storm.That decision reduces runoff，keeps fertilizer on the field，and helps controls farmer's costs.As data gathers season after season，computer models will help farmers better manage fertilizer and other additions to optimize production and minimize runoff.
   Remote sensing is another way that modern technology can help farmers know what's going on in their fields.Many farmers drive around to monitor growth and watch for pests and diseases.But these surveys are typically random and don't cover more than 2 percent of a field.Remote sensing can provide accurate data that covers an entire field and cables recommendations tailored to what's going on in the stricken area.

（1）What may the third agricultural revolution help farmers do in the future？
A．Make reasonable decisions.
B．Grasp computing ability.
C．Deal with big data.
D．Develop business potentials.
（2）Why did the author give an example in Paragraph 4 according to the text？
A．To confirm the coming of a storm.
B．To explain the reason of fertilizer runoff.
C．To stress the effect of information application.
D．To show the use of computer models.
（3）What is the advantage of the remote sensing technology？
A．It can show typical random.
B．It can drive up crop production
C．It can remove pests and diseases.
D．It can offer exact statistics.
（4）What is the author's attitude to the coming agriculture revolution？
A．Opposed.
B．Neutral.
C．Positive.
D．Unclear.

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
D．Eco-friendly Alternative
