213193. （2024•沣东中学•高二下期中） One of the most critical roles forests play is relieving climate change．Trees suck enormous amounts of carbon dioxide out of the air and fix the carbon in their wood and the soil．A recent study found that planting new trees over an area the size of the US could suck away two thirds of all the carbon dioxide discharge that humans have pumped into the atmosphere．
   "Without animals，it is harder for forests to absorb carbon，as tree species （种类） important for protecting the climate could be lost without animals"，Susanne Winter，a program director said at the WWF．
   In Africa，many of the tree species that absorb the most carbon rely on large birds and primates （灵长类动物） to eat their fruits and spread their large seeds，according to the report．Without them，those trees would have difficulty reproducing and forests would lose their best carbon-storing trees．
   "Forests are our greatest natural ally in the fight against global warming， " Winter said．"If we want to hold back the worldwide decline in biodiversity and prevent the climate crisis，we need to protect the forests and the species living there．
   Forests also filter（过滤） water- as water makes its way to lakes or groundwater reserves，the roots and soil separate it from deposits and pollution that it collects along the way．What's more，forests regulate the global water cycle，since trees' leaves，branches，and roots store or send out water vapor．
   Climate modelow that forest-cutting down in Central Africa could lead to a 15% drop in rainfall in the US Midwest，and Amazon deforestation （森林滥伐） could cut Texas rainfall by 25%．
   Humans also get food，wood，and medicine from the abundance of plants and animals in forests．Worldwide，1.6 billion people rely on forests for their livings，according to the United Nations．About 300 million people live in forests，according to WWF．

（1）What's the purpose of Paragraph 3？
A．To tell where the large seeds go．
B．To show the tree species in Africa．
C．To draw reader's attention to Africa．
D．To support Susanne Winter's opinion．
（2）What does the underlined word "ally" in Paragraph 4 probably mean？
A．Winner．
B．Competitor．
C．Partner．
D．Victim．
（3）How do forests change climate according to the passage？
A．By affecting air and water．
B．By feeding birds and animals．
C．By providing life necessities．
D．By increasing the variety of trees．
（4）What can be inferred from the passage？
A．Water should be filtered．
B．The more forests，the more rain．
C．Forestould be globally protected．
D．Half the carbon dioxide is sucked away by trees．

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

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

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

202244. （2022•临潼区•二模） The World Health Organization says the widespread use of sugar in food products and drinks is a major concern in many areas.So WHO officials are calling on governments to require taxes on sugary drinks in an effort to limit their usage and popularity.The officials believe the taxes also would reduce the risk of health problems resulting from obesity.
   Obesity is a condition in which the body stores large，unhealthy amounts of fat.Obese individuals are considered overweight.A new report says that in 2014 more than one-third of the adults in the world were overweight，and 500 million were considered obese.The United Nations agency estimates that in 2015，42 million children under age 5 were either overweight or obese.It says that number represents an increase of about 11 million during the past 15 years.Almost half of these boys and girls live in Asia and one-fourth in Africa.
   The U.N.agency blames unhealthy diets for a rise in diabetes cases.There are 422 million cases of the disease worldwide.Who says 1.5 million people die from it every year.It says the use of sugar in food products，like sugary drinks，is a major reason for the increase in rates of obesity and diabetes.
   Temo waqanivalu is with the agency's Department for the Prevention on Non-Communicable Diseases：He told VOA that taxing sugary drinks would reduce consumption and save lives.Waqanivalu noted that Mexico enacted a law of a 10 percent tax on sugary drinks in 2014.He said by the end of the year，there was a 6 percent drop in the consumption of such drinks.Among poor people，the number of people who consumed sugary drinks dropped by 17 percent.
   The WHO says people should limit the amount of sugar they consume.It says they should keep their sugar intake to below 10 percent of their total energy needs，and reduce it to less than 5 percent for improved health.

（1）Why are taxes on sugary drinks required？
A．To warn people to change their life style.
B．To readjust the economic structure.

202226. （2022•临潼区•一模） You probably don't think of scientific or medical instruments as the kind of instruments that actually make music.But now researchers have built a scientific instrument specifically designed to detect counterfeit（伪造的）medications through sound.
   The World Health Organization estimates about 10 percent of the medications in low and middle-income countries are fakes.Sometimes，dangerous ones.So the idea here is to fill the tube with a sample that's known to be safe.Then compare it to a bottle you're not so sure about.
   "If you get the same pitch（音高）out of those two samples，it's very good evidence that they're probably the same material，and the suspect substance is a safe drug to take.But if you get a different pitch out of the two samples，that's absolute proof that those two samples are chemically different.And that shows you there's something wrong with the sample you were given and you probably shouldn't take it."
   The instrument is designed to test only liquid samples for now.And while the human ear is sensitive enough to hear the difference between samples of air and water，the difference between a real and a counterfeit drug might be imperceptible to our ears.So Grover built a free website where users can upload recordings of the instrument，from their smartphone or computer，and analyze the hertz.Then repeat it with the suspect sample.
   ...in the hope of inspiring people around the world to build these things themselves. "I can literally make one of these out of junk in your garage in about five minutes probably.The hardest thing to come by is tubing.We've made them out of bent copper tubing like you get out of a radiator.Just junk，lying around.It's remarkable how easy they are to make.My dream would be to have the instructions for making them and using them shared as widely as possible."
   It is，admittedly，a pretty convincing pitch.

（1）What's the passage mainly about？
A．A scientific instrument.
B．A pretty convincing tube.
C．A suspect sample.
D．A dangerous instrument.
（2）What's the function of the instrument according to the passage？
A．To give the buyer more drugs as a gift.
B．To make the wonderful music.
C．To carry the liquid.
D．To test fake medications through sound.
（3）Where can you get the material to build this kind of scientific instrument？
A．The junk in the garage.
B．The junk in the drugstore.
C．The junk in the supermarket.
D．The junk in the factory.
（4）What can we learn about the instrument from the passage？
A．Everyone can make it easily.
B．It can play the music you like.
C．There is a long way to go.
D．It is widely used to test medicine.

203149. （2016•西安中学•一模） When Geoff Marcy was 14，his parents bought him a telescope．Every night，he would go onto the roof outside his window to see the wonders of the sky．
   "What excited me most was whether there were planets in other solar systems where life might exist，" he says． "I decided to try to find planets orbiting （沿…轨道运行） other stars like our Sun．"
   And he did． "My fellow researcher，Paul Butler，and I found our first planet in 1995，" Dr．Marcy says． "We worked for ten years without finding anything! But we stuck with it，and our patience paid off． "
   Since then，the two scientists have discovered 65 of the more than 100 planets found orbiting other stars．Dr．Marcy and Dr．Butler also spotted the first "family" of three planets．In June 2002 they announced another discovery：a Jupiter-like （像木星一样的） planet orbiting star 55 Cancri．
    At first，the two researchers found only planets that orbit close to stars．Recently，the scientists found planets farther out．The planet orbiting 55 Cancri is a major breakthrough：it is the first sighting of a large gas planet about the same distance from the star as Jupiter is from the Sun．
   Why is this important？Scientists think that life on Earth may exist because of two special features in our solar system．The first is Jupiter．
   "Because it's so big，Jupiter pulls comets and asteroids （小行星），or they all come and hit the Earth．" Dr．Marcy explains． "Without Jupiter，life on Earth would likely have been destroyed．"
   A second feature is that Earth is a rocky planet where liquid water，which is necessary for life，can exist．Unlike gas planets，rocky planets like Earth have surfaces where water can gather in pools and seas，which may support life．A huge space exists between the Jupiter-like planet and two other planets that lie close to 55 Cancri．Is there an Earth-like planet in the space，too small for us to notice？If so，says Dr．Marcy， "We would have two striking similarities to our solar system：a Jupiter-like planet and an Earth-like planet．And there may be life! "

（1）What can we learn about Dr．Marcy from the passage？
A．He is fond of watching Jupiter．
B．He is from a scientist family．
C．He dislikes working with Paul Butler．
D．He is interested in finding life in outer space．
（2）Which of the following is true of the recent discovery？
A．The planet is not as protective as Jupiter．
B．The planet is close to star 55 Cancri．
C．The planet proves to be a gas planet．
D．The planet is as large as Jupiter．
（3）Dr．Marcy thinks that life may exist in the 55 Cancri system because        ．
A．he has found the system similar to the solar system
B．he has discovered an Earth-like planet there
C．he has discovered a rocky planet there
D．he has found signs of life in the system
（4）"But we stuck with it" （in Paragraph 3）means        ．

213477. （2023•长安区一中•高一下期中） In many places，a moonless night sky is no longer totally black.Artificial lighting can give the night a lasting light.This so-called light pollution can affect animals.Even moderate light pollution，a new study finds，can roughly double how long a house sparrow infected with West Nile Virus （WNV） remains at high risk of spreading disease.If bitten by a mosquito，that virus can now spread to other animals，including people.
   "In the United States，house sparrows are about as widespread as artificial lighting.So they made a useful test species in a new first-of-its-kind study，" says Meredith Kernbach.Her team used these birds to test whether light at night might affect the spread of the West Nile Virus.
   Kernbach based much of her lab test on real-world conditions.In the study，some house sparrows in the lab spent the night in an area that was dimly （昏暗地） lit.These birds were slower in fighting off West Nile Virus infections than those that spent the night in full darkness.
   WNV needs a mosquito to spread from bird to bird，or from bird to human.If a mosquito doesn't pick up enough viruses from the blood of an infected animal，its new victim might be able to avoid getting sick.House sparrows kept under a dim night light typically had enough viruses in their blood to be a source of virus for at least four days，Kernbach reports.House sparrows in full darkness had enough viruses to spread the disease only for two days.
   What light does to the birds is only part of the story，points out Davide Dominon，a physiologist at the Nether-lands Institute of Ecology in Wageningen. "Researchers will need to look for effects on the virus itself，" he says. "And，of course，on the mosquitoes."

（1）Why are house sparrows chosen as the test species？
A．They are sensitive to light.
B．Their distribution is wide.
C．Mosquitoes like biting them.
D．Their immune system is weak.
（2）What can be inferred from the study？
A．West Nile Virus becomes stronger under light.
B．Darkness can help people avoid getting sick.
C．It's better for house sparrows to live in the dark.
D．It takes house sparrows longer to kill this virus under light.
（3）What does Davide Dominon say about the study？
A．It needs further study.
B．It's very useful.
C．New victims are ignored.
D．Other birdould be studied.
（4）What's the text mainly about？
A．Artificial lighting can affect house sparrows' reproduction.
B．Mosquitoes can spread WNV from animals to humans.
C．Light pollution lengthens the time of birds' spreading WNV.
D．The light pollution may help WNV develop slower.

203170. （2016•西安中学•四模） It is not only praise or punishment that determines a child's level of confidence．There are some other important ways we shape our kids-particularly by giving instructions and commands in a negative or positive choice of words．For example，we can say to a child"Don't run into traffic!"or"Stay on the footpath close to me．"In using the latter，you will be helping your kids to think and act positively，and to feel confident in a wide range of situations，because they know what to do，and aren't scaring themselves about what not to do．
   Actually，it is all in the way the human mind works．What we think，we automatically rehearse（预演）．For example，if someone offered you a million dollars not to think of a blue monkey for two minutes，you wouldn't be able to do it．When a child is told"Don't fall off the tree，"he will think of two things："don't"and"fall off the tree"．That is，he will automatically create the picture of falling off the tree in his mind．A child who is vividly imagining falling off the tree is much more likely to fall off．So it is far better to use"Hold on to the tree carefully"．
   Clear，positive instructions help kids to understand the right way to do things．Kids do not always know how to be safe，or how to react to the warning of the danger in negative words．So parentould make their commands positive．"Sam，hold on firm to the side of the boat"is much more useful than"Don't you dare to fall out of the boat？"or worse still"How do you think I'll feel if you drown？"The changes are small but difference is obvious．

202188. （2022•周至县•三模） The Royal Botanical Gardens，Kew，in the UK，are home to thousands of fascinating plants，but none are as lonely as the Encephalartos woodii （伍德苏铁），an ancient cycad species and，most likely，the last one of its kind.
   It was in 1895 that botanist John Wood noticed this interesting looking palm tree on a steep slope in southern Africa.Spellbound by its multiple trunks and arched palm fronds，Dr.Wood- who made his living collecting rare plants- had some stems removed and sent to London in a box.It ended up in the Palm House at the Royal Botanical Gardens，where it has been waiting for a mate for over a century.Despite numerous efforts to find it a mate，the Encephalartos woodii at Kew remains alone，unable to produce an offspring and reproduce its species.For this reason，many consider it the world's loneliest plant.
   Two hundred million years ago，when dinosaurs still roamed the world，cycads were everywhere.They made up around 20% of plants，acted aelter for some dinosaur species and as food supply for others.They managed to somehow survive five ice ages，adapted to coexist with new species of plants，but as time passed，their numbers dwindled.Like all other cycads，Encephalartos woodii went from numbering millions of specimens，to thousands，and today，possibly just one，a male.
   Some plants have both male and female organs，but not Encephalartos woodii.Without a female specimen to produce the seeds，it can never mate.
   The Encephalartos woodii is technically not the last of its kind.It has been cloned several times，and its clones can be found in several botanical gardens around the world.It can even mate with some closely related species，but it can't produce a true offspring.It just sits there，the last of its ancient species waiting for a female species to be found somewhere on Earth. "Surely this is the loneliest organism in the world，" biologist Richard Fortey once wrote， "growing older，alone，and fated to have no successors.Nobody knows how long it will live."

（1）What can we learn about the Encephalartos woodii？
A．It once was a common being with male and female organs.
B．It has been the last of its species for centuries.
C．Scientists' efforts to produce any young of it were in vain.
D．It used to play an important role in the survival of dinosaurs.
（2）What does the underlined word "dwindled" probably mean in Paragraph 3？
A．Declined.
B．Increased.
C．Multiplied.
D．Rocketed.
（3）What's Richard Fortey's attitude towards the plant？
A．Favorable.
B．Indifferent.
C．Sympathetic.
D．Skeptical.
（4）What is the best title for this text？
A．The last Cycad on Earth.
B．The World's Loneliest Plant.
C．The Plant that Outlived Dinosaurs.
D．The Ancient Cycad Found by John Wood.

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

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

What makes life difficult is that the process of facing and solving problems is a painful one．Problems，depending on their nature，cause us sadness，or loneliness or regret or anger or fear．These are uncomfortable feelings，often as painful as any kind of physical pain．And since life causes an endless series of problems，life is always difficult and is full of pain as well as joy．
Yet，it is in this whole process of solving problems that life has its meaning．Problems are the serious test that tells us success from failure．When we desire to encourage the growth of human spirit，we encourage the human ability to solve problems，just as in school we set problems for our children to solve．It is through the pain of meeting and working out problems that we learn．As Benjamin Franklin said，"Those things that hurt，instruct．"It is for this reason that wise people learn not to fear but to welcome the pain of problems．
（1）From the passage，it can be inferred that        ．
A．everybody has problems
B．we become stronger by meeting and solving the problems of life
C．life is difficult because our problems bring us pain
D．people like to complain about their problems

A．encourage them to learn
B．teach them to fear the pain of solving the problem
C．help them learn to deal with pain

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？
A．A diary.

203132. （2016•师大附中•二模） Using too much water or throwing rubbish into our rivers are clear ways that humans can put our water supply in danger，but we also affect our water supply in less obvious ways．You may wonder how paving（铺砌） a road can lead to less usable fresh water．A major part of the water we use every day is groundwater．Groundwater does not come from lakes or rivers．It comes from underground．The more roads and parking lots we pave，the less water can flow into the ground to become groundwater．
   Human activity is not responsible for all water shortages（缺乏）．Drier climates are of course more likely to have droughts（干旱） than areas with more rainfall，but in any case，good management can help to make sure there is enough water to meet our basic needs．
   Thinking about the way we use water every day can make a big difference，too．In the United States，a family of four can use 1.5 tons of water a day!Thiows how much we depend on water to live，but there's a lot we can do to lower the number．
   You can take steps to save water in your home．To start with，use the same glass for your drinking water all day．Wash it only once a day．Run your dishwasher only when it is full．Help your parents fix any leaks（滴水） in your home．You can even help to keep our water supply clean by recycling batteries（电池） instead of throwing them away．

205137. （2022•鄠邑区•高一下期末） A scientist locked himself in a small air-tight plastic tent with 200 plants to see if they could change CO₂ into oxygen （氧气） fast enough to keep him alive.
   Kurtis Baute locked himself in a 3 m by 3 m tent in his brother's backyard in British Columbia，Canada.He hoped to find out if by surrounding himself with plants，the CO₂ he breathed out could be changed into oxygen to allow him to survive in the locked tent for at least three days.
   Unfortunately，he had to give up the experiment after only 15 hours，as CO₂ levels reached a dangerous point where he risked suffering brain damage. "I could probably survive in the tent for three days，" Baute wrote on his website. "But my goal is not to just 'not die'.My goal is to end this project without developing brain damage or just generally causing lasting harm to my body.But as it turns out，that's exactly what he risked as the 200 plants he took with him into the tent couldn't meet his needs.Clearly，a cloudy sky prevented them from receiving all the sunlight they needed to perform photosynthesis （光合作用），so they couldn't recycle CO₂ fast enough.
   "Plants are great at taking in CO₂ and they love it.Since it wasn't a bright and sunny day，they weren't getting the light they needed，which meant CO₂ just kept rising.I had to give up the experiment as that continued." the young experimenter said.15 hours into the experiment，Baute reached the set danger point and then ended this experiment.Still，he called the experiment a "huge success" as his main goal was actually the terrible effects of climate change and CO₂ emissions.
   "The conclusion about my experiment is that if CO₂ is too high，I'll escape，which is just everyday experiences for many people on this planet.Everyone deserves clean air，but not everyone has it，" he wrote.

D．He couldn't survive in the locked tent any longer.
（2）What made it hard for the 200 plants to satisfy Kurtis Baute's needs？
A．His health condition.
B．His wrong decision.
C．Too much CO₂.
D．The cloudy weather.
（3）What does Kurtis think of the result of the experiment？
A．Disappointing.
B．Surprising.
C．Satisfying.
D．Interesting.
（4）What may be the best title for the text？
A．A test to show the importance of clean air.

202120. （2022•西安中学•二模） On a break from his studies in the MIT Media Lab，Anirudh Sharma traveled home to Mumbai，India.While there，he noticed that throughout the day his T-shirts were gradually gathering something that looked like dirt. "I realized this was air pollution，or sooty（像煤一样）particulate matter（PM），made of black particles released from exhaust（尾气）of vehicles，" Sharma says. "This is a major health issue." Soot consists of tiny black particles，about 2.5 micrometers or smaller，made of carbon produced by incomplete burning of fossil fuels.
   Back at MIT，Sharma set out to help solve this air-pollution issue.After years of research，Sharma's startup Graviky Labs has developed technology that attaches to exhaust systems of diesel generators（柴油发电机）to collect particulate matter.Scientists at Graviky then turn it into ink，called Air-Ink，for artists around the world.So far，the startup has collected 1.6 billion micrograms of particulate matter.More than 200 gallons of Air-Ink have been harvested for a growing community of more than 1，000 artists，from Bangalore to Boston，Shanghai，and London.
   Posted all over Graviky Lab's Facebook page today are photos of art made from the Air-Ink and paint，including street wall paintings，body art and clothing prints.At first，there was still no specific application for the ink.Then the startup decided to find new ways to further spread its mission.It chose to do so through art. "Art helps us raise awareness about where the ink and paint comes from.Air pollution knows no borders.Our ink sends a message that pollution is one of the resources in our world that's the hardest to collect and use.But it can be done，" Sharma says.

202100. （2022•西安中学•七模） Your house may have an effect on your figure.Experts say the way you design your home could play a role in whether you pack on the pounds or keep them off.You can make your environment work for you instead of against you.Here are some ways to turn your home into part of your diet plan.
   Open the curtains and turn up the lights.Dark environments are more likely to encourage overeating，for people are often less self-conscious（难为情）when they're in poorly lit places—and so more likely to eat lots of food.If your home doesn't have enough window light，get more lamps and flood the place with brightness.
   Mind the colors.Research suggests warm colors fuel our appetites.In one study，people who ate meals in a blue room consumed 33 percent less than those in a yellow or red room.Warm colors like yellow make food appear more appetizing，while cold colors make us feel less hungry.So when it's time to repaint，go blue.
   Don't forget the clock—or the radio.People who eat slowly tend to consume about 70 fewer calories（卡路里） per meal than those who rush through their meals.Begin keeping track of the time，and try to make dinner last at least 30 minutes.And while you're at it，actually sit down to eat.If you need some help slowing down，turn on relaxing music.It makes you less likely to rush through a meal.
   Downsize the dishes.Big serving bowls and plates can easily make us fat.We eat about 22 percent more when using a 12-inch plate instead of a 10-inch plate.When we choose a large spoon over a smaller one，total intake（摄入）jumps by 14 percent.And we'll pour about 30 percent more liquid into a short，wide glass than a tall，skinny glass.

（1）The text is especially helpful for those who care about        .
A．their home comforts
B．their body shape
C．house buying
D．healthy diets
（2）A home environment in blue can help people        .
A．Digest food better
B．Reduce body intake
C．Burn more calories
D．Regain their appetites
（3）What are people advised to do at mealtimes？
A．Eat quickly.
B．Play fast music.
C．Use smaller spoons.
D．Turn down the lights.
（4）What can be a suitable title for the text？
A．Is Your House Making You Fat？
B．Ways of Serving Dinner
C．Effects of Self-consciousness
D．Is Your Home Environment Relaxing？
