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

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

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.

204689. （2023•西安八十九中•高二上期末） OUCH!Shots hurt.But they prevent you from getting sick.How？By teaching your body how to fight germs （病菌）.Some vaccines （疫苗） contain germs of a specific disease that have either been killed or weakened，so the shots won't give you the disease.
   Quantities of white blood cells called "B cells" defend your body.Each one can recognize something that is not part of you.When a germ gets inside your body and meets its match，that B cell becomes active.It replicates itself，and thousands of B cells create "antibodies"，which attach to the germ and destroy it.
   One germ can turn into a million in a few hours.If you're weak，you will soon feel very sick.Meanwhile，your B cells are working hard and they will catch up with the growing numbers of germs in one or two weeks.At the height of the battle，B cells can make thousands of antibodies （抗体）in a second.That's when you start feeling better.
   After the germs are defeated，your body knows how to fight those specific germs because some B cells are memory B cells.Sometimes they can live for your entire life.They make you safe from a second infection （感染）.That fact is the basis for vaccination.Vaccines contain dead or weakened germs that let your body make memory B cells.If you later come across that same germ，memory B cells immediately start replicating themselves and making antibodies.Soon the germs are destroyed，and you probably won't even feel sick.
When Edward Jenner tried using cowpox to protect people from smallpox （天花），he had no idea about B cells or antibodies.Now we know that cowpox and smallpox are similar enough that the antibodies made against cowpox also kill the smallpox virus for a time.A hundred years after Jenner，Louis Pasteur formed the basis for vaccination：using a germ against itself.
（1）What does the underlined word "replicates" mean in the second paragraph？
A．Repairs.
B．Reproduces.
C．Replaces.
D．Recycles.
（2）People start feeling better after getting sick when        .
A．germs grow at a high speed
B．antibodies reach a high level
C．memory B cells come into being
D．B cells find the germ in your body
（3）What can we know about vaccines from the text？
A．Vaccineots may give people the disease.
B．Vaccines put antibodies in people's body.
C．Vaccines free people of various diseases.
D．Vaccines help people make memory B cells.
（4）Which of the following is the best title for the text？
A．How to Fight Germs.
B．What Are Vaccines.
C．How Vaccines Work.
D．Who Invented Vaccines.

202673. （2020•西安中学•三模） Even though vaccination（接种疫苗） is a powerful defense against disease，some voices are against it．In a recent letter，the American Medical Association（AMA） urged big social media including Amazon，Facebook and Google to take action to defend medical science on their platforms．
   It said that vaccine-preventable diseases that do harm to the public health like measles（麻疹） are on the rise．Measles cases worldwide jumped more than 30% in 2017 compared to 2016，with the largest increases seen among nations in the Americas，Europe and the Eastern Mediterranean．Vaccine-preventable diseases are increasing largely because many people are unwilling to get vaccinated．And some of these people even encourage others to refuse vaccination．So this year，the World Health Organization （WHO） declared the anti-vaccination movement a top-10 health threat．
   "Vaccination is one of the most cost-effective ways of avoiding disease - it currently prevents 2-3 million deaths a year，and a further 15 million could be avoided if global coverage of vaccinations improved，" WHO said．
   A research article published in 1998 in a medical journal suggested a link between a vaccine and the development of autism（自闭症） in young children．Although the research has been suspected and many other studies have proved that vaccinations do not cause autism，the article is still impressing people strongly today．Another reason for the growth in the anti-vaccination movement is widespread misinformation on social media，which can turn people against vaccination．If a concerned parent consistently sees information in their Newsfeed that casts doubt on the safety of vaccines，it could cause them to disregard the advice of their children's physicians and public health experts and refuse to follow the recommended vaccination schedule．So access to true information about vaccine safety is badly needed．

（1）What does the AMA require social media to do on their platforms？
A．Unite to develop new vaccines．
B．Stop vaccine misinformation．
C．Give up the anti-vaccination movement．
D．Introduce vaccine-preventable diseases．
（2）Why does the author mention the measles cases？
A．To declare measles can be prevented．
B．To prove vaccination doesn't work well．
C．To show the result of anti-vaccination．
D．To explain the reason for avoiding vaccination．
（3）Which of the following DOESN'T play a role in the anti-vaccination movement？
A．The costs of vaccination．
B．People's concerns over vaccine safety．
C．A research relating vaccination to autism．
D．Misinformation spread on social media platforms．
（4）What is the author's attitude towards vaccination？
A．Doubtful
B．Ambiguous
C．Positive
D．Negative

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．
D．A good mixed diet normally supplies sufficient vitamins for us．

204707. （2022•西安中学•高一下期末） American high school students are terrible writers，and one education reform group thinks it has an answer：robots.Or，more accurately，robot-readers—computers programmed to scan students' essays and spit out a grade.
   Mark Shermis，professor of the College of Education at the University of Akron，is helping to hold a contest，set up by the William and Flora Hewlett Foundation （WFHF），that promises ﹩ -100，000 in prize money to programmers who write the best automated grading software. "If you're a high school teacher and you give a writing task，you're walking home with 150 essays，" Shermis said. "You're going to need some help."
   Automated essay grading was first proposed in the 1960s，but computers back then were not up to the task.In the late 1990s，as technology improved，several textbooks and testing companies jumped into the field.Today，computers are used to grade essays on South Dakota's student writing assessments and a handful of other exams，including the TOEFL test of English fluency，taken by foreign students.
   The Hewlett contest aims to show that computers can grade as well as English teachers—only much more quickly and without all that depressing red ink. "Automated essay scoring is objective，" Shermis said. "And it can be done immediately.If students finish an essay at -10 pm，they will get a result at 10：01 pm."
   Take，for instance，the Intelligent Essay Assessor，a webbased tool marketed by Pearson Education，Inc.Within seconds，it can analyze an essay for spelling，grammar，organization，and help students to make revisions.The program scans for key words and analyzes semantic （语义的） patterns，and Pearson claims that it can understand the meaning of text much the same as a human reader.

A．robot-readers
B．education reform in America

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.

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

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

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.
