213359. （2023•西安中学•高一下期中） - Recent research discovered that a low-cost computer training program can help older persons drive less dangerously.
   "We developed a training program，called Drive Aware，which could be used by anyone who has a computer，" says Jing Feng，co-author of the study and a professor of psychology at NC State. "Drive Aware is a cognitive （认知的） training program for older persons that helps them notice traffic risks more effectively.The purpose of our recent study was to see how much Drive Aware changes trainees' driving behaviors once they get behind the wheel."
   The researchers found 27 persons aged 65 and up to test Drive Aware.In a driving simulator （模拟器），all of the study participants （参与者） experienced a basic driving exam.The "active training" group was made up of nine of the study participants.Every two weeks，the active training group had two Drive Aware trainings.A group of nine additional study participants was asked to take "passive training".This group watched videos of others receiving the Drive Aware instruction.This happened twice，with each lasting about a week.The control group，which was made up of the remaining nine study participants，received no training.After that，all 27 study participants performed a second driving exam in the simulator.
   The study participants in the active training group experienced 25% fewer "unsafe incidents （事件）" following the training，according to the researchers.There was no obvious change in the number of dangerous incidents among study participants in the passive training and control groups.
   "This testing was done with a fairly limited number of study participants，" Feng says. "If we can succeed in getting the fund，we'd like to further our testing with more people to clearly prove how effective this training is at reducing accidents among older drivers."

（1）What does the underlined phrase "get behind the wheel" in paragraph 2 mean？
A．Take a risk.
B．Start a program.
C．Drive a car.
D．Use a computer.
（2）What was the "passive training" group required to do？
A．Experience no training.
B．Receive two Drive Aware trainings.
C．Take three driving tests.
D．Observe videos of Drive Aware trainings.
（3）How did the researchers arrive at their testing result？
A．By quoting former figures.
B．By investigating car accidents.
C．By operating the driving simulator.
D．By comparing participants' performances.
（4）What is Feng's attitude towards the testing？

202938. （2017•师大附中•十一模） When I first got an email account ten years ago，I received communications only from family，friends，and colleagues．Now it seems that every time I check my e-mail，I have an endless series of advertisement and other correspondence that do not interest the at all．If we want e-mail to continue to be useful，we need special laws that make spamming（发送垃圾邮件） a crime．
   If lawmakers do not do something soon to prohibit spam，the problem will certainly get much worse．Computer programs allow spammers to spend hundreds of millions of e-mails almost instantly．As more and more advertisers turn to spam to sell their products，individual（个人的）e-mail boxes are often flooded with spam e-mails．Would people continue to use e-mail if they had to deal with an annoying amount of spam each time？
   This problem is troubling for individuals and companies as well．Many spam emails contain computer viruses that can shut down the entire network of a company．Companies rely on e-mail on for their employees to communicate with each other．Spam frequently causes failures in their local communications networks，and their employees are thus unable to communicate effectively．Such a situation results in a loss of productivity and requires companies to repeatedly repair their networks．These computer problems raise production costs of companies，which are，in the end，passed on to the consumer．
   For these reasons，I believe that lawmakers need to legislate （立法） against spam．Spammerould be fined，and perhaps sent to prison if they continue to disturb people．E-mail is a tool which helps people all over the world to communicate conveniently，but spam is destroying this convenience．

204622. （2023•高新一中•高二上期末） Dreams，according to Carl Jung，reveal a certain amount of reality hidden during waking consciousness.In Jungian philosophy，the conflict and chaos experienced in dreams finally bring order to our lives.While Jung's mystical theories are debatable，he was not mistaken about the importance of dreaming.A growing number of reportow that a continuous lack of dreaming is damaging our waking hours in many ways.
   This trend is causing damage to our immune and metabolic （新陈代谢的） systems，let alone the electronic products that keep us up late at night are ruining our sleep patterns，which has long-term consequences on our memory system.One study showed that not allowing mice to have adequate amounts of REM （Rapid Eye Movement） sleep，the stage in which we dream，the mice couldn't strengthen memories.
   You might think this is just a sleep problem，but dreaming is inseparable from our nighttime rest.We sleep in cycles，each lasting about 90 minutes；in a sleep cycle，we go through non-REM sleep before hitting REM.As the night progresses，REM sleep periods increase in length while deep sleep （one of the stages of non-REM sleep） decreases.The longer we sleep，the more time we spend in REM，which is why we are often dreaming when waking up in the morning.If we sleep less than seven hours，however，it becomes harder to achieve this level of REM.
   The combination of sleeping and dreaming acts as an emotional stabilizer.We recover from emotional hurt faster when we sleep and dream properly.However，we're not getting enough sleep to cycle through the stages to take advantage of this natural circadian anti-depressant （抗抑郁剂） — dreams.Instead，we get depressed and turn to alcohol or medicines to get to sleep，which only makes things worse because even one drink leads to late REM while anti-depressants promote deep sleep at the expense of REM.
   We're paying for this lack of dreaming in many ways.For example，a 2021 study stated that compared with quiet rest and non-REM sleep，REM promoted the formation of associative networks and the integration （整合） of unassociated information.Volunteers that experienced more REM sleep were better equipped for solving problems requiring creative solutions.
   Rowan Hooper，the managing editor at New Scientist，writes that dreams that include an "emotional core" appear to be a main function of REM sleep and that we should look at sleep patterns as seriously as we do diet and exercise habits.

（1）What's Carl Jung's view about dreams？
A．They cause chaos.
B．They damage immunity.
C．They reveal secrets.
D．They mirror reality.
（2）Why is the sleep process explained in paragraph 3？
A．To show a dream mainly occurs during REM sleep.
B．To prove the minimum sleep time should be seven hours.
C．To prove dream problems and sleep problems are attached.
D．To show people often dream when waking up in the morning.
（3）What conclusion can be inferred from paragraph 5？
A．REM sleep promotes creativity.
B．REM sleep helps fight depression.
C．The brain still receives new information during REM sleep.
D．The brain is paying the price for having more non-REM sleep.
（4）What's the main idea of the passage？
A．The importance of sleep lies in dreams.
B．The absence of dreams is terrible for us.
C．Dreaming patterns are more important than we realize.
D．Dreaming has mystical power of strengthening memories.

202540. （2021•西安中学•八模） A living，bio-degradable （可生物降解的）fabric named "Biogarmentry" has been invented.Made from algae （藻），the textile （纺织品） purifies the air around it through photosynthesis （光合作用）.
   Researchers claim it's the first living textile，and have fashioned the material into sheer，cloak-like garment.While prototypes （雏形） like these are still in the early stages of research and design，and far from mass production，they challenge the fashion industry to reimagine ways it can reduce its large carbon footprint through alternative fabrics.
   Fashion is one of the world's most polluting industries.It's responsible for more carbon emissions than international flights and shipping combined，amounting to 10% of all greenhouse gasses emitted globally.The crops traditionally used to make clothing absorb carbon as they grow，but most natural materials are still carbon emitters.Take a single T-shirt made of cotton as an example.The estimated footprint of a cotton shirt over its lifetime is 15 kilograms （33 pounds） of carbon dioxide，with most of that emitted during the energy-intensive production and dyeing（染色） processes.
   In recent years，environmental start-ups have proposed a number of alternative natural fibres，many of which have the potential to sequester carbon but none have been shown to achieve zero emissions.As algae has the ability to trap carbon，a carbon-negative raincoat made of marine algae has been created.Algae-based materials are，currently，where electric vehicle technologies were a decade ago.The technology is now ready for prime time.When the resulting garments are commercially available，we can imagine people wearing their own organic cloak，spraying their organism as they go to work and encouraging their algae to purify the air.

（1）What's the text mainly about？
A．A textile helping purify the air.
B．An industry causing pollution.
C．A way to achieve zero-emission.
D．A trend in the fashion industry.
（2）Which of the following is the most environmentally-friendly？
A．An international flight.
B．Clothing made of cotton.
C．A petrol-powered vehicle.
D．A raincoat made of algae.
（3）What does the underlined word "sequester" in Paragraph 4 probably mean？
A．increase.
B．create.
C．trap.
D．release.
（4）Which word best describes the author's attitude to algae-based materials？
A．Skeptical.
B．Optimistic.
C．Conservative.
D．Objective.

213514. （2022•长安区一中•高二上期中） Muscles make an excellent vaccine administration site because muscle tissue contains important immune cells.These immune cells recognize the antigen，a tiny piece of a virus or bacteria introduced by the vaccine that stimulates an immune response.In the case of the COVID-19 vaccine the immune cells in the muscle tissue pick up these antigens and present them to the lymph nodes.Injecting the vaccine into muscle tissue keeps the vaccine localized，allowing immune cells to sound the alarm to other immune cells and get to work.Once a vaccine is recognized by the immune cells in the muscle，these cells carry the antigen to lymph vessels，which transport the antigen-carrying immune cells into the lymph nodes.Lymph nodes，important parts of our immune system，contain more immune cells that recognize the antigens in vaccines and start the immune process of creating antibodies.
   Muscle tissue also tends to keep vaccine reactions localized.Injecting a vaccine into the deltoid muscle may result in local inflammation or soreness at the injection site.If certain vaccines are injected into fat issue，the chance of painful redness or swelling increases because fat tissue has poor blood supply，leading to poor absorption of some vaccine components.
   Yet another deciding factor in vaccine administration location is the size of the muscle.
   Adults and children aged three and older tend to receive vaccines in their upper arm in the deltoid.Younger children receive their vaccines mid-thigh because their arm muscles are smaller and less developed.
   Another consideration during vaccine administration is convenience and patient acceptability.
   Can you imagine taking down your pants at a clinic with strangers around？Rolling up your sleeve is much easier and more preferred.

（1）How many reasons are mentioned for the vaccines given in the muscle？
A．2.
B．3.
C．4.
D．5.
（2）Why do muscles make a good vaccine administration site？
A．Muscle tissue contains vital immune cells.
B．Muscle tissue stimulates immune responses.
C．Muscles can easily recognize bacteria.
D．Muscles can prevent reproduction of viruses.
（3）What could be a result of injecting vaccines into fat issues？
A．Poor blood supply.
B．Local pain.
C．Rapid fat loss.
D．Better absorption.
（4）Where is the passage most likely taken from？
A．An advertisement.
B．A novel.
C．A speech.

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.

213563. （2022•未央区•高二上期中） A new study discovers that sharks do sleep，and they often sleep with their eyes open.Since some sharks have to swim constantly to keep oxygen-rich water flowing over their gills （鱼鳃），people have long thought that they don't sleep at all.
   Researchers from Australia have now recorded a species of shark sleeping for the first time，finishing the long-standing debate about whether sharks sleep.To see if sharks were in fact asleep，the team analyzed the metabolism（新陈代谢）and pose of seven draughtsboard sharks （猫鲨）over 24 hours.When the sharks were resting for five minutes or longer，their oxygen consumption dropped，which suggested the animals were sleeping.And the researchers also noticed that the sharks changed their posture by lying flat and closer to the ground.
   The sharks sometimes slept with their eyeut as well，though，mostly during the day.At night，they tended to keep their eyes open more often，leading researchers to suspect that the sharks' eye closure might have more to do with light than the sleep state itself. "Not only are sleeping sharks less responsive to their surroundings，but they also have lower metabolic rate，" said Michael Kelly，an ecophysiologist at La Trobe University.
   "Sharks are an important group as they are the oldest living jawed vertebrates（颌类脊椎动物）—a character they share with us，"Michael Kelly said."Sharks have been swimming in the sea for over 400 million years and have evolved very little in that time.Understanding how and why these animals sleep will provide important understanding into the function of sleep and how the animal has evolved over time."
   The team points out that more research will be needed to see if other species sleep like the draughtsboard sharks.Next they plan to continue to analyze the sharks' brain activity while they sleep，to learn more about their waking and resting states.

（1）What is the previous misunderstanding about sharks？
A．They sleep with their eyes closed.
B．They breathe in flowing water.
C．They swim frequently at night.
D．They always stay awake.
（2）What do researchers find about draughtsboard sharks？
A．They need to rest every five minutes in the sea.
B．They consume much less oxygen during the day.
C．They have the same pose when awake and when asleep.
D．They might close their eyes not to sleep but to avoid light.
（3）What does paragraph 4 talk about？
A．The process of the research.
B．The findings ot the research.
C．The significance of the research.
D．The introduction of the researchers.
（4）What does the researchers think of their research in the last paragraph？
A．Insufficient.
B．Unrealistic.
C．Meaningless.

203805. （2024•周至四中•高一上期末）      What killed King Tut？Historians and scientists have long believed that ancient Egypt's most famous king was probably murdered.But a recent scientific study claims to have found a different answer to this more than 3，300-year-old mystery.A team of researchers now say that King Tut，the boy ruler，died of complications（并发症） from a broken leg.
   Tut's full name was Tutankhamun.He was just 9 years old when he became the ruler of Egypt.His treasure-filled tomb was discovered almost a century ago.It was filled with royal riches，including a solid-gold coffin，a gold mask，and piles of jewelry.
   Unfortunately Tut died at the age of 19.Many experts have thought that Tut was killed by one of his advisers，named Ay，who wanted to be king.But due to a major modern science project，the idea is wrong.
   Researchers set out to solve the mystery of King Tut's death by using the tools of science，including DNA tests and electronic scans of his mummy（木乃伊）.Scientist Carsten Pusch conducted the tests on Tut for the new study.He thinks a broken leg contributed to the young king's death.
   More than 100 walking sticks were found in King Tut's tomb.This supports the team's findings.But how could a person die from a simple broken leg？
   Pusch also found DNA evidence in Tut's body that indicates he had malaria（疟疾），a disease carried by mosquitoes.Malaria severely weakens the immune system.
   Pusch and his fellow researchers believe the malaria and the bone disease together caused the king's fracture（骨折） to become deadly.Finally，the young king was just too weak to recover.

（1）It has long been believed by historians and scientists that        .
A.King Tut was the youngest ruler in the world history
B.King Tut was the richest ruler in the history of Egypt
C.King Tut was murdered by one of his advisers
D.King Tut was poisoned by one of his servants
（2）From the passage we can learn that        .
A.the king had been dead for 3，300 years
B.the king was buried grandly
C.the king was born with a bad immune system
D.the king's body was well kept in the tomb

A.testing the king's immune system
B.studying the walking sticks found in the tomb
C.performing experiments on mosquitoes
D.applying DNA tests and electronic scan technology
（4）The passage mainly tells us about        .

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.
C．A further explanation of the research methods.
D．Further research based on current findings.

213667. （2023•鄠邑区•高一下期中）     Optical（光学的）fiber is a flexible line of glass capable of carrying information over long distances.Scientists Dr.Robert Maurer.Dr.Peter Schultz，and Dr.Donald Keck invented the first low-loss optical fiber in 1970.Inspired by their belief that information could be sent through light，they spent four years experimenting with different kinds of glass until they succeeded.
    Optical fiber was an answer to consumer demand for increased bandwidth （带宽）.Beginning in the 1960s.the telecommunications industry realized that the existing copper wire infrastructure（基础设施）could no longer keep up as communications traffic increased.Optical fiber changed the telecommunications industry greatly because it，unlike copper，offered limitless bandwidth.Because of those qualities，optical fiber has become the backbone of the networks that we use today to send voice，data，and video around the world.
    The first optical fiber was celebrated for having a total attenuation of 17 dB/km.Today，there are optical fibers with attenuation as low as 0.17 dB/km，which translates to signal loss being 100 times better than the first one.As a result，optical fiber is the preferred medium for fast.reliable communications networks.
    Today，optical fiber provides the infrastructure for broadband connectivity all around the world.Optical fiber supports all the communications and interactive technology we use every day.Because of the global fiber network，you have instant access to voice，information，and video through devices such as smartphones，computers，high-definition TV.CPS，and game systems through which you get directions，send email，conduct research.join social networks，shop，and download music，movies，and more.
    As has been the case from the very beginning，one driver that shapes the future of optical fiber is market demand.Optical fiber continues to create new opportunities in how we live，work，and play.Innovations such as Cloud Computing will enable us to partner with technology in a way never before possible.

（1）What drives the scientists to invent the optical fiber？
A．No enough copper.
B．Better understanding of light.
C．Invention of glass.
D．Need for faster information sending.
（2）What does the underlined word "attenuation" in Paragraph 3 mean？
A．Signal.
B．Loss.
C．Power.
D．Metal.
（3）What can we learn about the optical fiber in Paragraph 4？
A．It has limited usage.
B．It needs more devices.
C．It benefits life and technology.
D．It offers better resources.
（4）What is the passage mainly about？
A．The development and advantages of optical fiber.
B．The ways to develop optical fiber.
C．The future of optical fiber.
D．Different opinions about optical fiber.

212704. （2024•铁一中学•高二上期中）     Years ago，I bought a blouse.That same day，I considered putting it on，but for no particular reason I decided not to.That weekend，I again considered wearing the blouse，but the occasion didn't seem special enough，so again，I passed it up.Fast forward to today，I have never worn that blouse.
    What happened here？Why do people own so many unused possessions，treating them as though they are too special to use？To find out，I ran an experiment in which participants imagined buying a bottle of wine.We had half of the participants imagine considering opening it one night，but deciding not to.Then when we measured how special the wine seemed and participants' intentions to open it later，we found that those who had imagined holding off on opening it were in fact less likely to intend to open it later.When asked the reason，most assumed they were waiting for a future occasion to open it-a more special occasion.
    Why do people fall into this mental trap？Prior research points to two main reasons.
    First，when options are presented one at a time，rather than all at once，it can be difficult to know when to make a decision.So people often end up"holding out" for an idealized future occasion.Second，regardless of the actual reasons behind their feelings and actions，people often come up with their own explanations after the fact.
    Putting these together is a recipe for what psychologists term""specialness spirals".When you give up using something-for whatever reason-if you believe that you are waiting to use it，the possession will start to feel more special.And as you search for the right occasion day after day，it becomes more tempting to hold out for a future occasion.The less you use it，though，the more special it feels，and the cycle continues.Ultimately，the likelihood of using the possession becomes rarer and rarer.The more this happens，the more stuff you have lying around.
    How can you fight specialness spirals？Try committing in advance to using an item on a specific occasion.When buying a dress，tell yourself you'll wear it this weekend.Or when purchasing a candle，plan to light it that day.This strategy encourages you to actually enjoy your possessions.

（1）What were the participants asked to imagine doing in the experiment？
A.Putting off drinking the wine.
B.Evaluating the quality of the wine.
C.Listing reasons for drinking the wine.
D.Discussing how they would deal with the wine.
（2）What does the underlined word"tempting"in paragraph 5 mean？
A.Particular.
B.Ordinary.
C.Appealing.
D.Uninviting.
（3）What can we learn about specialness spirals？
A.They can mislead people into shopping traps.
B.They can lead to a collection of unused stuff.
C.They result from a pessimistic attitude to the future.
D.They help explain the psychology of delayed rewards.
（4）What is the main purpose of the text？
A.To explain a psychological phenomenon.
B To criticize a wrong consumption concept.
C.To remind people to enjoy their possessions.
D.To encourage people to prepare for a rainy day.

205388. （2020•西安中学•高三上期末） Getting rid of dirt，in the opinion of most people，is a good thing．However，there is nothing fixed about attitudes to dirt．
   In the early 16th century，people thought that dirt on the skin was a means to block out disease，as medical opinion had it that washing off dirt with hot water could open up the skin and let ills in．A particular danger was thought to lie in public baths．By 1538，the French king had closed the bath houses in his kingdom．So did the king of England in 1546．Thus began a long time when the rich and the poor in Europe lived with dirt in a friendly way．Henry IV，King of France，was famously dirty．Upon learning that a nobleman had taken a bath，the king ordered that，to avoid the attack of disease，the nobleman should not go out．
   Though the belief in the merit of dirt was long-lived，dirt has no longer been regarded as a nice neighbor ever since the 18th century．Scientifically speaking，cleaning away dirt is good to health．Clean water supply and hand washing are practical means of preventing disease．Yet，it seems that standards of cleanliness have moved beyond science since World WarⅡ．Advertisements repeatedly sell the idea；clothes need to be whiter than white，cloths ever softer，surfaces to shine．Has the hate for dirt，however，gone too far？
   Attitudes to dirt still differ hugely nowadays．Many first-time parents nervously try to warn their children off touching dirt，which might be responsible for the spread of disease．On the contrary，Mary Rucbush，an American immunologist（免疫学家），encourages children to play in the dirt to build up a strong immune system．And the latter position is gaining some ground．

（1）The kings of France and England in the 16th century closed bath houses because        ．
A．they lived healthily in a dirty environment．
B．they thought bath houses were to dirty to stay in
C．they believed disease could be spread in public baths
D．they considered bathing as the cause of skin disease
（2）Which of the following best describes Henry IV's attitude to bathing？
A．Afraid
B．Curious
C．Approving
D．Uninterested
（3）How does the passage mainly develop？
A．By providing examples．
B．By making comparisons．
C．By following the order of time．
D．By following the order of importance．
（4）What is the author's purpose in writing the passage？
A．To stress the role of dirt．
B．To introduce the history of dirt．
C．To call attention to the danger of dirt．
D．To present the change of views on dirt．
