201968. （2023•长安区•一模） Electronic sensors built into paper could be used in a range of ways from information storage to touch screens and more.
   Electronic sensors built into cartons（纸盒）may make it easier to tell when it's time to throw out rotten milk or orange juice.And that's just the start.At least that's the goal for researchers working on putting electronics into paper.They're trying to figure out how to combine the flexibility，low-cost and recyclability of paper with the information-carrying ability of electronics.
   Daniel Torbjork，a physics graduate student in Finland，has been working on the problem.He's published a review of the field in the journal Advanced Materials.
   Much research has been focused in this area.While most electronic applications require patterned conducting structures，conductive paper could be used in applications such as energy storage devices，sensors，electric heaters and others，according to Torbjork.
   "You could even have some interactive functions in magazines，" Torbjork said，"You could put a simple game in a package.If you want a touch screen，press a button and then something happen.Sensors in paper could tell us when something has gone bad."
   Additional applications，such as information storage and security paper，have been suggested for magnetic papers containing magnetite.In Massachusetts，researchers have figured out how to post a video of such a device put into a paper airplane.
   German researchers have also put electronic chips in paper bank notes to defend counter-feiters（造伪币者）.Paper is a good material but printing electronics also requires low-cost manufacturing.As many US and European paper makers lose market share to cheaper paper from China，these big paper companies are looking for added value products.That's where electronic paper devices could make a difference.
   "The major obstacles are paper's large surface roughness and chemical impurities." Torbjork says.But others in the field think that electronic sensors in paper are still far from the consumer marketplace.
   "I don't think it's going to happen." said Roy Horgan. "You need a conductive surface.It could be 10 years out.What we are looking for are solutions that you can commercialize today."
   Solar Print is partnering with Italian automaker Fiat to develop a unique auto-glass with tiny photostatic cells（光电）that can capture electricity from the sun.In the meantime，using paper to conduct electricity is still a "blue-sky" project.
   "I would love to see someone prove me wrong，because that means that it's actually happening." Horgan said. "If someone comes up with conductive paper，then that's a very interesting technology."

（1）Putting electronics into paper will        .
A．cut the cost and impurity of paper
B．depend on flexible conductive structure
C．help consume rotten milk or orange juice
D．combine the advantages of paper and electronics
（2）Paragraphs 4 to 7 mainly talk about the         of the conductive paper.
A．theories

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？

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？

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.

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？

B．The junk in the drugstore.
C．The junk in the supermarket.

（4）What can we learn about the instrument from the passage？

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.
C．To limit their use and popularity.
D．To ensure the market's diverse development.
（2）What do the figures in the second paragraph suggest？
A．Obesity is a severe worldwide problem.
B．Adult obesity is ignored at present.
C．Obesity can block economic development.
D．Obesity is most serious in developed countries.
（3）What does the underlined word "enacted" mean in the passage？
A．Abolished.
B．Passed.
C．Promised.
D．Reduced.
（4）What does the example of Mexico prove？
A．Tax policies are unfair to the poor.
B．Taxing sugary drinks makes a difference.
C．The poor consume more sugary drinks.
D．Sugary drinks are a threat to health.

201826. （2024•西安中学•九模） In February of 1942，Mexican farmer Dionisio Pulido thought he heard thunder coming from his cornfield.However，the sound wasn't coming from the sky.The source was a large smoking break sending out gas and pushing out rocks.This opening would come to be known as the volcano Paricutin，and over the next 9 years，its lava and ash would cover over 200 square km.But where did this new volcano come from，and what caused its unpredictable eruption？
   One of the most common causes of an eruption is an increase in magmastatic（静磁）pressure.Magma（岩浆）contains various elements and compounds.At high enough concentrations，compounds like water or sulfur（硫）form high-pressure gas bubbles.When these balls of gas reach the surface，they can burst with the force of a gunshot.And when millions of bubbles explode，the energy can send ash into the air.But before they pop or burst，they act like bubbles of CO₂ in a shaken soda.
   Not all eruptions are due to rising magmastatic pressure- sometimes the weight of the rock above can become dangerously low.Landslides can remove massive quantities of rock from atop a magma chamber or room，dropping the pressure and instantly touching off an eruption.This process is known as "unloading" and it's been responsible for numerous eruptions，including the sudden explosion of Mount St.Helens in 1980.But unloading can also happen over longer periods of time due heating ice or melting glaciers.In fact，many geologists are worried that glacial melt caused by climate change could increase volcanic activity.
   Unfortunately，knowing what causes eruptions doesn't make them easy to predict.While scientists can roughly determine the strength and weight of the Earth's crust（地壳），the depth and heat of magma chambers makes measuring changes in magmastatic pressure very difficult.But volcanologists are constantly exploring new technology to overcome this rocky field.Advances in thermal imaging（热成像）have allowed scientists to detect underground hotspots.Spectrometers can analyze gases escaping magma.Hopefully，these tools will help us better understand these gas breaks and their explosive eruptions.

（1）Why does the author mention the story of a farmer in the first paragraph？
A．To show the power of volcano eruption.
B．To introduce the topic.
C．To introduce the volcano Paricutin.
D．To explain the reason.
（2）What does the underlined word "they" in paragraph 2 refer to？
A．The bubbles of CO₂ .
B．The ash of the volcano.
C．Gas bubbles of compounds.
D．The elements of a soda.
（3）Which of the following is true about the eruption of Mount St.Helens？
A．Landslideould be responsible for its eruption.
B．It began to explode over a long period of time.
C．The process of "unloading" occurred after its explosion.
D．The weight of the rock above it increased as to cause its eruption.
（4）What can we infer from the last paragraph？
A．Scientists can determine the eruption of volcano in advance.
B．It is quite difficult to measure the weight of the Earth's crust.
C．Spectrometers can help scientists to detect underground hotspots.
D．Scientists are positive about further study of volcano eruption.

202281. （2022•西工大附中•七模） It is not easy to excite New Yorkers or keep them going easy on things around.This is one reason why actors and other famous people move to the city.They can live quieter lives and escape the paparazzi photographers who would follow them in Hollywood.
   But New York has a new media star.And this star is not living so quietly.The star is a colorful Mandarin duck.The bird first appeared this month in a small body of water in Manhattan's Central Park.Large crowds have gathered to see the duck.Reporters have been following its every move.The media attention on the duck has earned the name "quackarazzi" – a word combination of paparazzi and the sound a duck makes!
   The duck has chosen to live in a costly part of New York -- just off Fifth Avenue，near the historic Plaza Hotel.There，hundreds of people turn up every day，hoping to see the bird show off its extremely colorful feathers.Many people like the duck because its colors are like "sunsets，" says New Yorker Joe Amato.He comes to the park nearly every day with his camera equipment.Bird lovers have been keeping record of the bird's daily life through social media postings and videos.People have noted how effortlessly the duck moves through the water.
   This week，New York's newest celebrity seemed to enjoy its fame，showing off its wings while members of the "quackarazzi" pushed each other to get a closer look.Leesa Beckmann traveled over two hours from her home in New Jersey to see the duck.She says her 90-year-old mother has been talking all about the duck since its first appearance.
   "I've got to see this...duck，" Beckmann told her mother.She plans to take pictures and give them to her mother.
   Bird expert Paul Sweet heads a large collection of bird species at the New York-based American Museum of Natural History.He says there is nothing special about a Mandarin duck in Central Park.Central Park Zoo has its own Mandarin duck，he says.These ducks are often imported to the United States from Asia for use on private property.
   "A lot of non-birders tend to see （colorful） birds as more beautiful，" Sweet said， "But to me，it's no more beautiful than，say，a sparrow."

201693. （2024•西工大附中•模拟） California has lost half its big trees since the 1930s，according to a study to be published Tuesday and climate change seems to be a major factor．
    The number of trees larger than two feet across has declined by 50 percent on more than 46，000 square miles of California forests，the new study finds．No area was spared or unaffected，from the foggy northern coast to the Sierra Nevada Mountains to the San Gabriels above Los Angeles．In the Sierra high country，the number of big trees has fallen by more than 55 percent；in parts of southern California the decline was nearly 75 percent．
   Many factors contributed to the decline，said Patrick Mclntyre，an ecologist who was the lead author of the study．Woodcutters targeted big trees．Housing development pushed into the woods．Aggressive wildfire control has left California forests crowded with small trees that compete with big trees for resources（资源）．
   But in comparing a study of California forests done in the 1920s and 1930s with another one between 2001 and 2010，Mclntyre and his colleagues documented a widespread death of big trees that was evident even in wildlands protected from woodcutting or development．
    The loss of big trees was greatest in areas where trees had suffered the greatest water shortage．The researchers figured out water stress with a computer model that calculated how much water trees were getting in comparison with how much they needed，taking into account such things as rainfall，air temperature，dampness of soil，and the timing of snowmelt（融雪）．
   Since the 1930s，Mclntyre said，the biggest factors driving up water stress in the state have been rising temperatures，which cause trees to lose more water to the air，and earlier snowmelt，which reduces the water supply available to trees during the dry season．

（1）What is the second paragraph mainly about？
A．The seriousness of big-tree loss in California．
B．The increasing variety of California big trees．
C．The distribution of big trees in California forests．
D．The influence of farming on big trees in California．
（2）Which of the following is well-intentioned but may be bad for big trees？
A．Ecological studies of forests．
B．Banning woodcutting．
C．Limiting housing development．
D．Fire control measures．
（3）What is a major cause of the water shortage according to Mclntyre？
A．Inadequate snowmelt．
B．A longer dry season．
C．A warmer climate．
D．Dampness of the air．
（4）What can be a suitable title for the text？
A．California's Forests：Where Have All the Big Trees Gone？
B．Cutting of Big Trees to Be Prohibited in California Soon．
C．Why Are the Big Trees Important to California Forests？
D．Patrick Mclntyre：Grow More Big Trees in California

202282. （2022•西工大附中•七模） Innovation has pretty much finished with car tires （轮胎） right，I mean，what's left to change？How about the whole "air" part？
   Michelin Company's attempt to tackle tire rubbish around the world witnessed them roll out puncture-proof "airless" tires，which they say should help reduce the 18% of all world tires that are abandoned early due to punctures （轮胎漏气）.Deserted tires are a huge worldwide waste problem—the U.S.produces 260 million abandoned tires per year，many of which end up in landfills or on the sides of the freeway where they release harmful gases and micro-plastic pollutants as they break down.
   Michelin Company's Unique Puncture Proof Tire System or "UPTIS" is designed using 46% recycled material，and made from a plastic matrix （母体） mixed with glass fibers that provide a flexible outer layer with a strong inner one. "The truly distinctive structure of the Michelin UPTIS prototype（原型），or its "strangeness" as we have often heard it called，really attracted the eye of many visitors and left a lasting impression on them，" stated Cyrille Roget，Michelin Group Technical and Scientific Communications Director. "It was an unusual experience for us，and our greatest satisfaction came at the end of the demonstration when our passengers，who were undoubtedly a little alert（警觉）at first，said they felt no difference compared with conventional tires."
   Michelin Company believes airless tires will improve everyone's lives.Maintenance （保养） costs for company's vehicle fleets will be less expensive，and inexperienced car owners won't accidentally ruin their rubbers when driving them because they are over-or under-inflated（充气）.Although they are still in development stage and using at a large scale within years is unlikely to be available，Michelin Company is not in the least doubtful about their tires' future.

（1）Why does the author ask questions in the first paragraph？
A．To explain a strange phenomenon.

A．The new tire runs more smoothly.
B．The world greatly needs airless tires.
C．Traditional tires threaten the environment.
D．Michelin Company battles the issue of wasted tires.
（3）What do we know about "UPTIS"？
A．Its structure distances visitors.
B．It only uses recycled materials.
C．It combines plastic and glass fibers.
D．Its comfortableness beats ordinary tires.
（4）What's Michelin Company's attitude towards their new tires？

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.

202388. （2021•西安中学•十模） Researchers at the University of Maryland have turned ordinary sheets of wood into transparent material that is nearly as clear as glass，but stronger and with better insulating properties（隔热性）.It could become an energy efficient building material in the future.
   Wood is made of two basic ingredients：cellulose，which are tiny fibres，and lignin （木质素），which is a glue-like material that bonds the fibres together to give it strength.The lignin also contains molecules called chromophores，which give the wood its brown color and prevent light from passing through.
   Early attempts to make transparent wood involved removing the lignin，but this involved harmful chemicals，high temperatures and a lot of time，making the product expensive and somewhat fragile.The new technique is so cheap and easy that it could literally be done in a backyard.
   Starting with pieces of wood a meter long and one millimeter thick，the scientists simply brushed on a solution（溶液）of hydrogen peroxide using an ordinary paint brush.When left in the sun，or under a UV lamp for an hour or so，the peroxide remove color from the brown chromophores but left the lignin undamaged，so the wood turned white.Next，they filled the wood with a tough transparent epoxy，which filled in the spaces in the wood and then hardened.This made the white wood transparent.
   As window material，it would be much more resistant to accidental breakage.The clear wood is lighter than glass，with better insulating properties，which is important because windows are a major source of heat loss in buildings.It also might take less energy to produce clear wood because there are no high temperatures involved.
   Transparent wood could become an alternative to glass in energy efficient buildings，or perhaps coverings for solar panels in harsh environments.There could be no end of uses.

（1）What is the second paragraph mainly about？
A．The classification of wood strength.
B．The characteristics of wood.
C．The causes of wood color.
D．The structure of wood.
（2）How did the researchers make wood transparent in the past？
A．By removing the lignin.
B．By reducing chemicals.
C．By lowering the temperature.
D．By changing the experiment site.
（3）What is the function of the epoxy？
A．To make the wood stronger.
B．To take away the brown color.
C．To turn the wood transparent.
D．To fill the spaces in the wood.
（4）Which can be a suitable title for the text？
A．Replacing Glass with Wood
B．Turning Wood Transparent
C．Energy Saving Material
D．Eco-friendly Alternative
