203824. (2024•周至四中•高二上期末) Agricultural scientists in Switzerland have demonstrated the long-term effect of organic farming methods.Organic farms use no man-made chemicals to increase crops or control insects and disease.The study showed that organic fields produced fewer crops,on average,than other fields.However,the scientists say the organic methods improved the health of the soil and used half as much energy.
   The Swiss scientists compared the effects of organic and traditional farming methods over a period of more than twenty years.They grew crops on four fields of land in Switzerland.Two fields were grown using traditional farming methods.The others were grown using organic farming methods.The crops and soil use were similar in all the fields studied.
   The study found that the organic fields produced about 20% fewer crops than the other fields.However,the farmers used less fertilizer and energy on the organic fields.They found the organic fields were healthier.
   The scientists say the organic fields had more nutrients in the soil.The soils in the organic fields also had more biological activity than the other fields.The organic fields had more helpful organisms and a larger number of different organisms.The organic fields had almost two times as many insects,including helpful insects.In traditional farming,chemicals designed to kill harmful insects also kill helpful ones.
   The researchers say the findingow that organic crop production rates change little over time,and that soil fertility increases.They say the finds suggest that organic farmers can help the environment by increasing soil fertility.
   Organic farming is becoming increasingly popular in some countries.Many people believe that eating organic food is more healthful than eating food grown with chemicals.Some people are willing to pay more money to buy organic food.

(1)What does the study show about the organic methods?        
A.They have more output than other fields.
B.They benefit the health of the human and the soil.
C.They use more energy than traditional ones.

203380. (2016•西工大附中•四模) A recent study,while showing a generally positive attitude toward science,also suggests a widespread worry that it may be "running out of control".This idea is dangerous.
   Science can be a force for evil as well as for good.Its applications can be channeled either way,depending on our decisions.The decisions we make,personally or collectively,will determine the outcomes of science.But here is a real danger.Science is advancing so fast and is so strongly influenced by businesses that we are likely to believe whatever decisions we come to will make little difference.And,rather than fighting for the best possible policies,we may step back and do nothing.
   Some people go even further.They say that despite the moral and legal objections(反对),whatever is scientifically possible will be done-somewhere,sometime.They believe that science will get out of control in the end.This belief is dangerous too,because it fuels a sense of hopelessness and discourages them from making efforts to build a safer world.
   In our interconnected world,the lack of agreement in and out of the world of science can lead to the failure to control the use of science.Without a common understanding,the challenges of "controlling" science in this century will be really tough.Take human cloning for example.Despite the general agreement among scientists on its possible huge impact(影响) on traditional moral values,some countries still go ahead with the research and development of its related techniques.The outcomes are hard to predict.
   Therefore,discussions on how science is applied should be extended far beyond scientific societies.Only through the united efforts of people with hope,can we be fully safe against the misuse of science and can science best serve mankind in the future.

(1)What can we conclude from the recent study?        
A.People think highly of science.
B.Science is getting dangerously out of control.
C.People hold mixed opinions about science.
D.Science is used for both good and bad purposes.
(2)According to the passage,what will happen if we hold that science is getting beyond control?        
A.The development of science will hopelessly slow down.
B.The public will lose faith in bringing about a bright future.
C.Businesses will have even greater influence on science.
D.People will work more actively to put science under control.
(3)The discussion should reach beyond scientific societies because        
A.scientists have failed to predict the outcomes
B.the ties between different areas need strengthening
C.united efforts are necessary for the development of science
D.people need to work together to prevent the bad use of science
(4)What is the main idea of the passage?        
A.Science and its applications bring us many dangers.
B.Mankind can largely take control of science with their efforts.
C.The future of science will be influenced by the dangerous ideas.
D.The development of science mostly lies in people's attitudes.

201865. (2024•西安一中•三模)     Fossils (化石),the preserved remains of ancient life,serve as windows into the Earth's rich history.The formation of the fossils is a wonderful journey that unfolds over vast stretches of time,catching good views of the diversity of life that once lived on our planet.
    The journey often starts with the death of an organism in a specific environment.Whether it's a plant,animal or microscopic organisms,the key factor lies in whether the remains are quickly buried.This initial step is critical to protect the organism from its enemies and environmental factors that could lead to breakdown.
    As the remains are buried,they experience layers of sediment (沉积层).Over time,more layers gather,pressing the lower sediments.This process,known as sedimentation,plays a crucial role in preserving the remains by creating a protective environment that protects them from being destroyed.
    Mineralization is also a key period in the fossilization process.It involves the infiltration (过滤) of minerals into the organic tissues of the buried remains.Groundwater,rich in minerals moves through these layers.The minerals replace the original organic material,transforming the remains into rock-like forms.
    Sometimes,fossilization goes beyond mineralization to a process called petrification.Petrified fossils occur when the organic material is entirely replaced by minerals,often resulting in a good copy of the original organism.This transformation can preserve complex details,such as the skeletal features of animals.For softer organisms or parts like leaves or feathers,the fossilization process involves pressure.Under the weight of sediments,these delicate structures flatten but leave behind detailed imprints.
    The final step in the journey comes when geological processes expose the fossilized remains.Archaeologists then unearth these treasures,revealing the secrets of Earth's ancient inhabitants.This scientific exploration contributes to our understanding of evolution,biodiversity,and the ever-changing landscapes that have shaped the history of life on our planet.

(1)What is the role of fossils in the modern times?        ?
A.To help protect our environment.
B.To help explore the function of the Earth.
C.To enhance knowing the long history of the universe.
D.To provide an insight into the diverse life forms.
(2)Which of the following is the first step of fossilization?        ?
A.The quick pressure caused by rocks.
B.The quick transformation of the remains.
C.The rapid burial of the remains.
D.The mix of groundwater and minerals.
(3)How can a good copy of organisms form?        ?
A.By fossils petrified when minerals replace the organic material.
B.By groundwater moving through them.
C.By accumulating more pressure on them.
D.By creating a protective environment.
(4)What's the text mainly about?        ?
A.The importance of fossils.
B.The process of fossilization.
C.The evolution of ancient animals.
D.The preservation of the remains.

201884. (2024•周至县•一模)      Since 2001,robotic tools have revolutionized the practice of surgery.They have greatly reduced the stress and physical demands normally placed on surgeons and have made certain procedures possible.
    One example is "keyhole surgery",or minimally invasive (微创) surgery,which normally requires surgeons to stand at awkward angles and make difficult movements with their hands to make a cut inside the patient.But in June 2022,surgeon James Ansell used 3 D glasses and two sticks to control four robotic arms to perform a procedure to remove a cancerous tumor. "My colleague said...that this feels like cheating," Ansell said to The Guardian.
    Another area of surgery that has had major technological breakthroughs in recent years is telesurgery.Normally,telesurgery relies on a wired connection due to concerns of harming the patient should a wireless connection drop during surgery,but China made several advancements in wireless telesurgery based on 5 G technology.
    China achieved the first 5 G-based remote operation in March 2019 involving a brain surgery procedure between a surgeon in Sanya and a patient in Beijing,a distance totaling nearly 3,000 kilometers.More recently,a team of surgeons successfully completed remote micron-level eye surgery on rabbits located in a different city.The rabbits were at the Sun Yat-sen University in Guangzhbù,Guangdon g province,whereas the surgical team who operated on them via a 5 G robot were at the Hainan Eye Hospital in Haikou,Hainan province.
    Looking to the future,people hope that remote surgery could become commonplace to help heal injured soldiers on the battlefield while keeping surgeons at a safe distance.Some even believe that robotic systems,combined with AI,could one day exceed human surgeons.
    But,given current technological limitations and the high costs of these robots which can cost millions of dollars,the complete robot takeover of surgery may still be a while off.

(1)What does the "keyhole surgery" example intend to show?        
A.Great complexity of robotic surgery.

203777. (2024•铁一中学•高一上期末)     Despite the fact that parrots are well known for their long lives and complex cognition (认知),it remains unknown whether the two traits(特征) have influenced each other.
    "The problem has been sourcing good quality data," said Simeon Smeele,a doctoral student at the Max Planck Institute of Animal Behavior (MPI-AB) and lead author of a study published in Proceedings of the Royal Society B that tried to solve this question.
    Scientists from the MPI-AB and the Max Planck Institute for Evolutionary Anthropology (MPI-EvA) teamed up with Species360 to compile data from over 130,000 individual parrots sourced from over 1,000 zoos to find the average life span of 217 parrot species.
    The analysis revealed an astonishing diversity in life expectancy,ranging from an average of two years for the fig parrot up to an average of 30 years for the scarlet macaw.
    Next,the team tried to determine whether or not parrots' renowned cognitive abilities had any influence on their longevity.Their results support the theory that increased brain size has enabled longer lifespans.Because brain size relative to body size can be an indicator of intelligence,the findings suggested that the parrots with larger brains were able to survive for longer in the wild.
    The scientists were surprised that factors such as diet,or the greater developmental time required to develop larger brains,did not lead to longer average lifespans. "We would have expected the developmental path to play a more important role because in primates it is this developmental cost that explains the link between brain size and longevity," said Smeele.
    In the future,the team plan to explore if sociality and cultural learning in parrots might have also contributed to long lifespans.Smeele said: "Large-brained birds might spend more time socially learning foraging(觅食) techniques that have been around for multiple generations.This increased learning period could potentially also explain the longer life spans,as it takes more time but also makes the foraging repertoire(全部技能) more adaptive."

(1)What did the study aim to find out about parrots?        
A The diversity in their life expectancies.
B.The factors that influence their intelligence.
C.The traits that help them survive in the wild.
D.The link between their cognition and life spans.
(2)How did the researchers carry out their study?        
A.By surveying over 1,000 zoos.
B.By examining parrots' brains.
C.By analyzing the collected data.
D.By observing parrots' behavior.
(3)Which is a possible cause of parrots' longevity?        
A.Their diet.
B.Their body size.
C.Their larger brains.
D.Their brains development time.
(4)What is the last paragraph mainly about?        
A.Supporting evidence for the research results.
B.Potential applications of the research findings.

204706. (2022•西安中学•高一下期末) Students and Technology in the Classroom I love my blackberry (黑莓手机)— it's my little connection to the larger world that can go anywhere with me.I also love my laptop computer,as it holds all of my writing and thoughts.Despite this love of technology,I know that there are times when I need to move away from these devices (设备) and truly communicate with others.
   On one occasion,I teach a course called History Matters for a group of higher education managers.My goals for the class include a full discussion of historical themes and ideas.Because I want students to thoroughly study the material and exchange their ideas with each other in the classroom,I have a rule-no laptops,IPads,phones,etc.When students were told my rule in advance of the class,some of them were not happy.
   Most students think that my reasons for this rule include unpleasant experiences in the past with students misusing technology.There's a bit of truth to that.Some students think that I am anti-technology.There's no truth in that at all.I love technology and try to keep up with it so I can relate to my students.
   The real reason why I ask students to leave technology at the door is that I think there are very few places in which we can have deep conversations and engage complex ideas.Interruptions by technology often break concentration (专心) and allow for too much dependence on outside information for ideas.I want students to dig deep within themselves for inspiration and ideas.I want them to push each other to think differently and make connections between the course material and the class discussion.
   I've been teaching my history class in this way for many years and the evaluations reflect student satisfaction with the environment that I create.Students realize that with deep conversation and challenge,they learn at a level that helps them keep the course material beyond the classroom.
   I'm not saying that I won't ever change my mind about technology use in my history class,but until I hear a rally good reason for the change,I'm sticking to my plan.A few hours of technology-free dialogue is just too sweet to give up.

(1)Some of the students in the history class were unhappy with        .
A.the course material
B.others' misuse of technology
C.discussion topics
D.the author's class rules
(2)The underlined word "engage" in para.4 probably means        .
A.explore
B.accept
C.change
D.refuse
(3)According to the author,the use of technology in the classroom may        .
A.keep students from doing independent thinking
B.encourage students to have deep conversations
C.help students to better understand difficult themes
D.affect students' concentration on the teacher's ideas
(4)It can be inferred from the last paragraph that the author        .
A.is quite stubborn in teaching
B.will give up teaching history
C.will change his teaching plan soon
D.values technology-free dialogues in his class

201903. (2024•长安区•一模)     When wind blows through a bigleaf maple (大叶枫),paper-thin,wing-like seeds called samaras gently spin towards the ground.The fruit's tissue allows the wind to guide it further away from the tree.Inspired by the seeds,researchers designed a tiny,winged microchip,no larger than a grain of sand,that is powerful enough to monitor environmental pollution and airborne disease.
    Called the microflier,the microchip has no motor to push it forward in the air but instead was designed to catch the wind.To perfect the microchip's flying capability and shape,scientists took inspiration from the forms of various airborne seeds.The research team improved various designs until the microfliers flew slowly and more steadily than nature's samara seeds.The slower falling rate allows the microchip to keep flying for longer,which gives it more time to collect data and monitor air pollutants and airborne diseases.
    To perfect the microflier's flight,researchers took inspiration from children's pop-up books to create the three-dimensional wings.Usually,electronic microchips are flat,two-dimensional objects,but something flat won't take flight.To make the 3-D shape,John.
A.Rogers and his team built a stretched rubber base that the microchip rests on.The wings pop into flight mode when the rubber base is relaxed.
    The chip gathers data with sensors across its surface that can sense and monitor pH levels,test for heavy metals or chemicals,and track air pollution.An antenna (天线) on the microflier then sends all the collected data to a computer or phone.Rogers and his team are planning to test out the electronic chips soon by dropping thousands of the chips in a field.The microfliers will change color depending on the number of heavy metals present in the field where they land.A drone will then fly over the area and take photos of the microflier's colors,allowing researchers to map out the pollutants.
    Rogers and his team also designed the microchips to break down over time to prevent environmental pollution.

(1)What is the winged microchip designed to do?        
A.Guide seeds from the tree.
B.Prevent airborne diseases.
C.Keep track of air qualities.
D.Catch the wind to fly away.
(2)What do paragraph 2 and 3 focus on?

D.Why the microflier flies more stably.
(3)What do the researchers do with the microflier in the future?        
A.Drop chips in the field.
B.Monitor the soil color.
C.Map out air pollutants.
D.Handle soil pollution.
(4)Which of the following would be a suitable title for the text?        
A.Winged microchips for monitoring environment
B.Microflier:A flying device of spreading seeds
C.Drone:A photographer of microflier's colors

201921. (2024•临潼区•二模)     Artificial intelligence models can trick each other into disobeying their creators and providing banned instructions for making drugs,or even building a bomb,suggesting that preventing such AI "jailbreaks" is more difficult than it seems.
    Many publicly available large language models (LLMs),such as ChatGPT,have hard-coded rules that aim to prevent them from exhibiting racial or sexual discrimination,or answering questions with illegal or problematic answers — things they have learned from humans via training data.But that hasn't stopped people from finding carefully designed instructions that block these protections,known as "jailbreaks",making AI models disobey the rules.
    Now,Arush Tagade at Leap Laboratories and his co-workers have found a process of jailbreaks.They found that they could simply instruct one LLM to convince other models to adopt a persona (角色),which is able to answer questions the base model has been programmed to refuse.This process is called "persona modulation (调节)".
    Tagade says this approach works because much of the training data consumed by large models comes from online conversations,and the models learn to act in certain ways in response to different inputs.By having the right conversation with a model,it is possible to make it adopt a particular persona,causing it to act differently.
    There is also an idea in AI circles,one yet to be proven,that creating lots of rules for an AI to prevent it displaying unwanted behaviour can accidentally create a blueprint for a model to act that way.This potentially leaves the AI easy to be tricked into taking on an evil persona. "If you're forcing your model to be good persona,it somewhat understands what a bad persona is," says Tagade.
    Yinzhen Li at Imperial College London says it is worrying how current models can be misused,but developers need to weigh such risks with the potential benefits of LLMs. "Like drugs,they also have side effects that need to be controlled," she says.

(1)What does the AI jailbreak refer to?        
A.The technique to break restrictions of AI models.
B.The initiative to set hard-coded rules for AI models.
C.The capability of AI models improving themselves.
D.The process of AI models learning new information.
(2)What can we know about the persona modulation?        
A.It can help AI models understand emotions.
B.It prevents AI learning via online conversations.
C.It can make AI models adopt a particular persona.
D.It forces AI models to follow only good persona.

203689. (2024•西安中学•高三上期末)     Saving lives has always been an important mission of science.Now science,and indeed all society,are facing a new dilemma:whether or not to try and save more lives through human cloning.
   The first cloning experiments in the 1950s involved frogs and toads.It was not until 1997 that scientists successfully cloned the first mammal,the now world-famoueep known as Dolly.Cloning techniques' have continued to improve since then,and today there are cloned mice,salmon,and cattle.
   Some scientists want to apply the methods used in cloning animals to produce skin,or organs,and other body parts for humans.One of these methods involves taking adult cells from the brain or blood and growing them into new tissues.Another more complex technique takes embryo cells and develops them into a wide variety of cell types and tissues.It is this planned use of human embryos that has resulted in controversy and criticism.
   The cloning of human cells provides the potential to find cures and eliminate diseases.The dream of some researchers is to create a Utopian world of good health.Others question whether it is right to "Play God""in an attempt to cure the disabilities and diseases in this world.
   Some of the great hopes for cloning include the utility to perform transplants,whenever they are needed,using cloned organs.For example,people with lung cancer may simply have their lungs replaced with healthy ones.Scientists also look forward to the day when people in wheelchairs can walk again,and illnesses such as Alzheinmier's and Parkinson's Disease can be prevented.
   However,a lot of people worry about the appearance of masses of identical people,and the production of "perfect"" humans for warfare or slave labor.We might even see headless human bodies being stored at hospitals for their"spare parts".With such thought-causing possibilities for the 2 lst century,human cloning will no doubt continue to receive widespread attention and scrutiny(审视).

(1)What problem is science faced with?        
A.How to carry out human cloning scientifically.
B.Whether human cloning can help save more lives.
C.How to save more lives through human cloning.
D.Whether human cloning should be used for saving lives.
(2)What can we know about cloning according to the text?        
A.It has a history of over half a century.
B.It develops very quickly in the 21st century.
C.It can protect people from diseases of any kind.
D.It has enabled many people in wheelchairs to walk again.

203572. (2025•临潼区•高一上期末)     Your ears are already dark,wet and full of oils and dead skin—a delicious meal for many bacteria (细菌).It seems that wearing headphones could only make that environment more inviting to these bacteria.
    Actually,a 2008 study at Manipal University in India found that frequent (频繁的) use of headphones did increase the population of bacteria in the ear—mostly the staphylococcus,a common skin bacterium.And in 1992,a study at the Navy Medical Research Institute in Bethesda,Maryland in the US,found that the kind of over-the-ear headphones used by airlines had 11 times more bacteria after having been worn for just one hour.
    As unpleasant as this sounds,there is no need to worry about it.The headphones in the second study were clean before use,so began with a very low bacterial population and that increase resulted in a fairly low number in absolute terms.
    Also,this increase was not fast enough to increase the reproduction of bacteria.The study's authors said that most of the bacteria must already have been present in the deeper skins.The dark warm conditions while wearing headphones just encouraged some of them to come out and play.Furthermore,there are no signs that these bacteria can cause any harm.A 2002 study of call centre workers in Malaysia found no connections between headphone use and the illness in the ear.
    The bacteria that increase in your ear while you listen to music are the ones that live there normally,and your ear is able to deal with them.However,several studies have suggested that repeatedly putting on and taking off headphones may increase the risk of skin abrasions (擦伤) that allow harmful bacteria to get in and cause illnesses.

203544. (2025•铁一中学•高二上期末)     Artificial intelligence models can trick each other into disobeying their creators and providing banned instructions for making drugs,or even building a bomb,suggesting that preventing such AI "jailbreaks" is more difficult than it seems.
    Many publicly available large language models (LLMs),such as ChatGPT,have hard-coded rules that aim to prevent them from exhibiting racial or sexual discrimination,or answering questions with illegal or problematic answers—things they have learned from humans via training data.But that hasn't stopped people from finding carefully designed instructions that block these protections,known as "jailbreaks",making AI models disobey the rules.
    Now,Arush Tagade at Leap Laboratories and his co-workers have found a process of jailbreaks.They found that they could simply instruct one LLM to convince other models to adopt a persona (角色),which is able to answer questions the base model has been programmed to refuse.This process is called "persona modulation (调节)".
    Tagade says this approach works because much of the training data consumed by large models comes from online conversations,and the models learn to act in certain ways in response to different inputs.By having the right conversation with a model,it is possible to make it adopt a particular persona,causing it to act differently.
    There is also an idea in AI circles,one yet to be proven,that creating lots of rules for an AI to prevent it displaying unwanted behaviour can accidentally create a blueprint for a model to act that way.This potentially leaves the AI easy to be tricked into taking on an evil persona. "If you're forcing your model to be good persona,it somewhat understands what a bad persona is," says Tagade.
    Yinzhen Li at Imperial College London says it is worrying how current models can be misused,but developers need to weigh such risks with the potential benefits of LLMs. "Like drugs,they also have side effects that need to be controlled," she says.

A.It can help AI models understand emotions.
B.It prevents AI learning via online conversations.
C.It forces AI models to follow only good personas.
D.It can make AI models adopt a particular persona.
(3)What may the author suggest by saying the underlined sentence in the last paragraph?        
A.The risks of LLMs cannot be ignored.
B.We need to control the side effects of drugs.
C.It's worthwhile to explore LLMs' potential benefits.
D.We should restrict the development of LLMs.
(4)Which can be a suitable title for the text?

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

(1)What can ChatGPT possibly do according to paragraph 1?        
A.Study in medical school.
B.Start an online conversation.
C.Conduct a study independently.
D.Pass a challenging examination.
(2)What does underlined words "red herrings" in paragraph 3 refer to?        
A.Appealing topics.
B.Efficient helpers.
C.Hidden resources.
D.Distracting facts.
(3)According to Nature,ChatGPT can't be listed as an author because        .
A.it has invented all the data based on inaccurate information
B.it doesn't actively create and is not responsible for the work
C.it doesn't have a bank account and can't receive payment
D.it has failed to demonstrate problem-solving skills
(4)What is Tseng's attitude towards the future of ChatGPT?        
A.Interested yet doubtful.
B.Disinterested and calm.
C.Confident yet cautious.
D.Critical and disappointed.

205255. (2021•阎良区•高一下期末) Canadians have a global reputation(名声)for being polite.A survey ranked Canada first out of 50 countries.Most Canadians think that while being polite can be a superficial attitude when people are communicating with friend and strangers,being "kind" to others generally requires a much greater effort and truly knows who you are as a person.
   A national survey made by Environics Research Group for Coca-Cola Canada shows that on average each Canadian haown kindness to others through random (随意的)actions four times in the last four weeks.Examples of their kindness include things such as opening a door for a stranger,offering to carry heavy items or giving up your seat for someone else in a public bus.
   With millions of acts of kindness happening every day,most Canadians surveyed felt kind folks deserved more recognition for their actions.Coca-Cola Canada has decided to praise some very special individuals who make others happy with good acts in their own communities.The goal is to share their stories to help inspire others to give a little kindness too.
   "When it comes to kindness,seeing really is believing," says Carolyn Harty,Senior Brand Manager of Coca-Cola. "More than half of Canadians are inspired to pay it forward themselves when they see others making a kind gesture.It is these small acts of kindness that make a large difference and inspire people and create happiness. "
   Sixteen-year-old Sheliza Kassam,from Canada,decided on her thirteenth birthday that instead of gifts,she and her family would help feed families in need.Her small action became larger and developed into a non-profit organization that Sheliza now runs to hold birthday parties for children living in shelters who otherwise would not be able to celebrate their special day.
   Another teen Nathan Unrau started out with a one-time school charity project that just couldn't help.With the support of his parents,Lunches with Love has become a non-profit organization that makes and gives away 450 paper bag lunches to the local homeless people every other Saturday.

202064. (2022•西安中学•三模) Humans are not the only ones that like gold.Australian scientists have discovered a new fungus (真菌) that decorates its long,thread-like tendrils (卷须) with gold collected from the soil.The experts desperately hope the "gold digger" will provide information on the locations of gold deposits and make searching for the precious metal easier,and more environmentally friendly.
   The gold-loving fungus was discovered accidentally by a team of researchers led by Dr.Tsing Bohu,a scientist at Australia national science agency,CSIRO,when they were examining the microbes(微生物) in the soil at Boddington,a tiny town home to Australia's largest gold mine.
   A closer analysis suggested that the fungus uses chemical interactions with underground minerals to accumulate gold from its surroundings.Though fungi often interact with other things in nature,the reaction with gold was unexpected. "Fungi are well-known for playing an important role in the recycling of organic material,such as leaves and bark,as well as for the cycling of other metals," Dr.Bohu explained. "But gold is so chemically inactive that this interaction is both unusual and surprising."
   The fungi are not wearing the gold for beauty. "There is a biological benefit from this reaction." Dr.Bohu said, "Gold-loving fungi can grow faster and bigger relative to other fungi that don't work with gold."
   The researchers still need to conduct further analysis to understand the relationship between the fungi and the precious metal.More importantly,they need to determine if its presence is a sure sign of the existence of large deposits of the metal underground.The scientists also believe the fungi could be used to detect the presence of gold in waste products and man-made electronics.
   However,those hoping to get free gold from the fungi are in for a disappointment,for the delicate fungus is hard to see.Also,its gold can only be seen under a microscope.

(1)What are the experts starved of?        
A.Investigation the sites
B.Excavating the gold mines
C.Getting further informed
D.Unearthing gold deposits
(2)What could be learnt according to Dr.Bohu?        
A.Fungi's interaction with gold is unexpected but beneficial.
B.Gold's classification is biologically identified by fungi.
C.Fungi's formation with gold is fairly natural and frequent.
D.Gold is chemically accumulated by fungi's evolution.
(3)How does the author find the finding?        
A.It excites the gold diggers' motivation.
B.It has a long way to go before confirmation.
C.It lays the foundation of geological studies.
D.It ensures the search of gold sites.
(4)What can be the suitable title for the text?        
A.Beauty-loving Fungi Wrapped by Gold
B.Gold-loving Fungi Discovered in Australia
C.Boddington,Austria's Largest Gold Mine
D.New Discovery of Gold with Fungi
