212858. （2023•西安中学•高一上期中）     Over the last two days in December last year，nearly 30 tornadoes caused great damage across six states—from Arkansas in the south to Illinois in the midwest.More than 100 tornado warnings were issued—the most ever for a day.The tornado in Kentucky caused at least 50 people's deaths.which was described as the worst in this state's history.
    As one of the largest countries in the world，the United States is also one of the most geographically various countries—from deserts to forests to miles of coastline.While this comes with many advantages，it unfortunately leaves the country easily damaged by all kinds of natural disasters.
    Different parts of the United States face different types of natural disasters.The west coast is at risk of wildfires，earthquakes，and even volcanic eruptions.The southern part of the country is frequently hit by tornadoes，and the east coast faces the threat of serious hurricanes every year.Midwestern areas near rivers are often flooded by huge floods，and these are the worst floods in American history.
    The governments reviewed the weather event in each state's history that caused the highest number of deaths to determine the worst natural disaster in every state.Thanks to their location and geographic research，some states made preparations ahead of time to avoid mass-casualty （重大伤亡的） weather events.
    However，many other parts of the country have been less fortunate，experiencing massive storms and floods.Many such events，like the 1900 hurricane that hit Galveston of Texas，killed so many people that it was impossible to get an exact number of final deaths，especially，during that time.
    American weather continues to become more changeable.In 2018，there were 14 weather events that caused over ＄1 billion in damage.And in many parts of the country，these weather events could become even more destructive （毁灭性的） because of global warming.

（1）What do we know from the numbers in paragraph 1？
A.Less and less natural disasters hit America.
B.Tornadoes were the greatest threat to Americans.
C.The tornado in Kentucky was the worst in America.
D.America suffered from serious natural disasters.
（2）What does paragraph 3 mainly talk about？
A.The natural disasters in different parts of US.
B.The earthquakes in the west coast of US.
C.The hurricanes along the east coast of US.
D.The worst floods in American history.
（3）Which of the following can best describe American's weather in the future？
A.Controllable.
B.Unchangeable.
C.Pleasant.
D.Worrying.

（1）推理判断题。根据第一段Over the last two days in December last year，nearly 30 tornadoes caused great damage across six states — from Arkansas in the south to Illinois in the midwest.More than 100 tornado warnings were issued — the most ever for a day.The tornado in Kentucky caused at least 50 people's deaths，which was described as the worst in this state's history.（在去年12月的最后两天里，从南部的阿肯色州到中西部的伊利诺伊州，近30次龙卷风在六个州造成了巨大的破坏，发布了100多个龙卷风警告，这是有史以来最多的一天。肯塔基州的龙卷风造成至少50人死亡，这被描述为该州历史上最严重的一次。）可知，通过第一段的数字我们知道美国遭受了严重的自然灾害。故选D项。
（2）段落大意题。根据第三段The west coast is at risk of wildfires，earthquakes，and even volcanic eruptions.The southern part of the country is frequently hit by tornadoes，and the east coast faces the threat of serious hurricanes every year.Midwestern areas near rivers are often flooded by huge floods，and these are the worst floods in American history.（西海岸面临野火、地震甚至火山爆发的风险。该国南部地区经常受到龙卷风的袭击，东海岸每年都面临严重飓风的威胁。靠近河流的中西部地区经常被巨大的洪水淹没，这些都是美国历史上最严重的洪水。）可知，第三段主要介绍了美国不同地区的自然灾害。故选A项。
（3）观点态度题。根据最后一段American weather continues to become more changeable.In 2018，there were 14 weather events that caused over ＄ 1 billion in damage.And in many parts of the country，these weather events could become even more destructive（毁灭性的） because of global warming. （美国的天气继续变得更加多变。2018年，有14个天气事件，造成超过10亿美元的损失。在该国的许多地方，由于全球变暖，这些天气事件可能会变得更具毁灭性。）可知，美国的天气多变，可能会变得更具毁灭性。由此推知，美国未来的天气令人担忧。故选D。

204774. （2022•周至县•高一上期末） Trust me，you don't want to get caught under a tsunami!Tsunamis are one of the world's most powerful natural forces.They can cause huge amounts of damage.
   But do you know exactly what a tsunami is？They are huge，powerful waves in the ocean that grow as they reach the shore.Most tsunamis are actually caused by earthquakes.An earthquake happens when a big piece of the Earth's crust（地壳）suddenly moves.When the piece of ocean floor moves，it creates big holes.The water floods in to fill these holes.When the water moves that quickly，it creates a huge wave.This is how tsunamis are born!
   Other natural disasters like landslides，volcanic eruptions，and glaciers breaking off can also cause tsunamis.Once the water starts moving because of the force of the disaster，large waves begin to spread.These waves can move very fast.They have been recorded at speeds from 400 up to 500 miles per hour!They can also move across very long distances.
   At first，the waves of the tsunami may not seem that tall.That's because when the waves travel through the deep parts of the ocean，the top of each wave is very short.But as that wave comes near to the coast，it grows in height.Remember，the tsunami travels quickly.If you are sitting on a beach，you may not see the wave coming at first.But when the wave arrives，it will be like a towering wall of water.Some waves are as tall as 100 feet high.The biggest tsunami ever recorded happened in 1958 in Lituya Bay，Alaska.The wave was over 1，720 feet tall，and it wiped out trees，vegetation，and everything else in its way.
   As frightening as tsunamis can be，you don't need to worry too much about them.They don't happen that often.Only about two tsunamis happen every year.And it is said that serious，really damaging tsunamis only happen about every fifteen years.So don't worry.

（1）According to the article，which natural disaster is not responsible for causing a tsunami？
A．Tornadoes.
B．Volcanic eruptions.
C．Earthquakes.
D．Landslides.
（2）If a tsunami forms in the deep ocean，2，000 miles off the coast of Sri Lanka，how long at least
will it take the tsunami to reach the coast of SriLanka ？
A．1 hours.
B．2 hours.
C．4 hours.
D．6 hours.
（3）Which of the following about tsunami is TRUE？
A．The waves of the tsunami always move slowly over a long distance.
B．People on a ship in the deep ocean will notice a tsunami at once as soon as it forms.
C．If you are sitting on a beach，you must see the wave coming at first.
D．People will not notice a tsunami until it gets close to the coast.
（4）Where would this passage most likely to be found？
A．In a music magazine.
B．In a science newspaper.
C．In a travel guide.
D．In a story book.

201550. （2025•西安中学•一模）     As part of a post-fire response and recovery project，the Debris Flow Hazard Team（泥石流危害小组） is engaging in several studies to better understand the drivers of post-fire debris flows and improve post-fire hazard assessments across the Pacific Northwest.Wildfires make debris flows easy to happen，a fast-moving mixture of water，soil，and rock that can cause property damage and loss of life.
    After a wildfire，emergency managers need rapid answers to the questions：Where are debris flows likely？How much rain will it take to cause a debris flow？And how big will that debris flow be？Researchers are conducting applied research and emergency hazard assessments to answer these questions.Evaluated burn areas they've assessed included the nearly 2021 Dixie fire，the 2020 Labor Day wildfires，and many of the 2021 wildfires in Washington.
    The models used for hazard assessment have been developed and tested in drier places.But the models have not been tested widely in wetter places.Are the models accurate for wetter regions？Researchers have begun monitoring post-fire debris-flow activity in wetter places to answer the question.Post-fire monitoring involves measuring the rainfall within the burned areas and recording the flow response after rainstorms.The observed flow response is compared to the predicted possibility.If the model predicted a high possibility of debris flow and there was a debris flow，the model got it right.
    Recent data bespeaks both similarities and differences in debris-flow processes between the areas with higher humidity（湿度） and drier areas.For example，in the 2021 Dixie fire，major debris flows were caused by short bursts of intense rainfall like they are in drier places.In contrast，debris flows in the 2017 Eagle Creek Fire were caused by long time rainfall.Continued observation and testing is expected to lead to an improved set of hazard assessment models.
    Other frequently asked questions after wildfires are：How far will debris flows travel？What will be impacted？And how long will the burned areas remain dangerous？These questions are presently not resolved in current debris-flow hazard assessments，but the researchers are doing research to provide answers soon.

（1）What is the first paragraph mainly about？
A.Contents included in a project.
B.Hazards caused by debris flows.
C.Causes of post-fire debris flows.
D.Reasons for conducting the studies.
（2）What places are current studies focusing on？
A.Places seldom noticed.
B.Places with debris flow records.
C.Places with higher humidity.
D.Places once affected by wildfires.
（3）What does the underlined word"bespeaks"mean in paragraph 4？
A.Replaces.
B.Reveals.
C.Recognizes.
D.Recommends.
（4）What may be included in the next studies according to the text？
A.Methods to prevent debris flows.
B.Possible effects of debris flows.
C.The lasting time of the debris flows.
D.Other risks in the burned areas.

204337. （2023•未央区•高二上期末） The US government has recently helped people learn more about the dangers of earthquakes by publishing a map.This map shows the chances of an earthquake in catch part of the country.The areas of the map where earthquakes are most likely to occur are called earthquake belts.The government is spending a great deal of money and is working hard to help to discover the answers to these two questions：
   Can we predict earthquakes？
   Can we control earthquakes？
   To answer the first question，scientists are looking very closely at the most active fault （断层） systems in the country，such as the San Andreas fault in California.A fault is a break between two sections of the earth's surface.These breaks between sections are the places where earthquakes occur.But it will probably be many years before we can predict earthquakes correctly.And the control of earthquakes is even farther away.
   However there have been some interesting developments in the field of controlling earthquakes.The most interesting development concerns the Rocky Mountain Arsenal earthquakes.Here water was put into a layer of rocks 4，000 metres below the surface of the ground.Shortly after this injection （注射） of water，there was a small number of earthquakes.Scientists have decided that the water which was injected into the rocks worked like oil on each other.
   When the water"oiled"the fault，the fault became slippery and the energy of an earthquake was given out.Scientists are still experimenting at the site of these earthquakes.They have realized that there is a connection between the injection of the water and the earthquake activity.They have suggested that it might be possible to use this knowledge to prevent very big，dangerous earthquakes，that is，scientists could inject some kind of fluid like water into faults and change on a big earthquake into a number of small，harmless earthquakes.

（1）Earthquakes belts are        .
A．maps that show where earthquakes are likely to occur
B．zones with a high probability of earthquakes
C．breaks between two sections of the earth's surface
D．the two layers of earth along a fault
（2）The San Andreas fault is        .
A．an active fault system
B．a place where earthquakes have been predicted correctly
C．a place where earthquakes have been controlled
D．at the foot of the Rocky Mountain
（3）What did scientists learn about earthquakes at the Rocky Mountain Arsenal？
A．They occur at about 4.000 metres belowground level
B．The injection of water into earthquake faults prevent earthquakes from occurring.
C．They are usually caused by the oil in the faults.
D．Harmful earthquakes could be prevented by causing harmless earthquakes.
（4）What can be said about the experiments at the Rocky Mountain Arsenal？
A．They have no practical value in earthquake prevention.
B．They may have practical value in earthquake prevention.
C．They are certain to have practical value in earthquake prevention.
D．Nothing is told about their practical value in earthquake prevention.

203112. （2016•师大附中•十模） In my early 30s，I used an expired（过期的） student ID to buy discounted movie tickets．I'd tell myself，I'm buying a ticket I wouldn't have otherwise bought．I think many people have done similar things；however，we still think of ourselves as honest citizens．Researchers who study these behaviours believe that character isn't the real reason．We might break the rules under some conditions and in some mind-sets，but not in others．
Years ago，Francesca Gino，a professor at Harvard，and Dan Ariely，a behavioural economist at Duke，wondered if people with highter IQs were more likely to cheat．They found that cleverness wasn't closely connected to dishonesty，but creativity was．The more creative you are，the easier it is to retell the story of what happened when you behaved dishonestly．
Harvard University psychologist Joshua Greene argues in his book Moral Tribe that we may be born without having a clear sense of right and wrong，but our culture sharpens it．If your tribe downloads pirated（盗版）music，you're likely to go with the flow．
Harvard researcher Leslie John，along with two colleagues conducted an experiment．They told volunteers that others in the room were making more money than they were for getting questions right on a test．Guess what happened？That group，which considered itself disadvantaged，cheated more than those who believed that everyone received an equal payment．
The real threat is that rule breaking worsens over time．Behavioural psychology offers a few antidotes．Keep yourself fed and well-rested-we're likelier to behave badly when hungry or tied．Reflect on how your actions look through others' eyes and see yourselves in a positive light．In a Stanford study，when researchers uesed the verb cheat-please don't cheat-participants still cheated freely because they felt distanced （疏远）from the act．When the noun was used-don't be a cheater-hardly anyone did．
（1）According to Francesca Gino，who are likeliest to break the rules in a company？
A．Accountants．
B．Designers
C．Cleaners．
D．Typists．
（2）Why did volunteers in Leslie John's experiment cheat more than others？
A．Because they were not as smart as others．
B．Because they thought others cheated too．
C．Because they felt a sense of unfairness．
D．Because they were tired and hungry．
（3）The underlined word"antidotes"in the last paragraph can be replaced by        ．

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.

（2）What is the main idea of the second paragraph？
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？
A．Tolerant.

205754. （2018•西安一中•高一上期末） The most popular PE class at Waukegan High School in Illinois，US，takes place in a basement field house．
It is the school's version of CrossFit，the difficult physical exercise that has exploded in popularity over the last 16 years at thousands of gyms．It has more than one million devotees（爱好者） and a professional competition shown on ESPN．
Schools around the Chicago area have adopted CrossFit to interest students at a time of a rising weight problem among young people，and most say it really works compared with traditional gym classes．
"I think it's a great way to teach kids lifelong fitness，especially those kids who aren't interested in hockey（曲棍球），soccer or basketball，"said the teacher，Tracy Haraf from Illinois' Stony Creek Elementary，which devotes half of its PE days to CrossFit exercises． "They think it's tough，but I think they have a lot of fun doing it．"

202939. （2017•师大附中•十一模） When students and parents are asked to rate subjects according to their importance，the arts are unavoidably at the bottom of the list．Music is nice ，people seem to say ，but not important．Too often it is viewed as entertainment，but certainly not an education priority（优先）．This view iortsighted．In fact，music education is beneficial and important for all students
   Music tells us who we are．Because music is an expression of the beings who create it，it reflects their thinking and values，as well as the social environment it came from．Rock music represents a lifestyle just as surely as does a Schubert song．The jazz influence that George Gershwin and other musicians introduced into their music is obviously American because it came from American musical traditions．Music expresses our character and values．It gives us identity as a society．
   Music provides a kind of perception（视角）that cannot be acquired any other way．Science can explain how the sun rises and sets．The arts explore the emotive（情感的）meaning of the same phenomenon．We need every possible way to discover and respond to our world for one simple but powerful reason：No one way can get it all．
   The arts are forms of thought as powerful in what they communicate as mathematical and scientific symbols．They are ways we human beings "talk" to each other．They are the language of civilization through which we express our fears，our curiosities our hungers，our discoveries，our hopes．The arts are ways we give form to our ideas and imagination so that they can be shared with others．When we do not give children access to an important way of expressing themselves such as music，we take away from them the meanings that music expresses．
   So music education is far more necessary than people seem to realize．

（1）According to paragraph 1，students       ．
A．regard music as a way of entertainment
B．disagree with their parents on education
C．view music as an overlooked subject

D．prove music influences people's lifestyles
（3）According to the passage ，the arts and science       ．
A．approach the world from different angles
B．explore different phenomena of the world
C．express people's feeling in different ways
D．explain what it means to be human differently
（4）What is the main idea of the passage？
A．Music education deserves more attention．
B．Music should be of top education priority．

202958. （2017•师大附中•七模） Dreams can be familiar and strange，fantastical or boring，but some dreams might be connected to the mental processes that help us learn．In a recent study，scientists found a connection between nap-time dreams and better memory in people who were learning a new skill．
   In the study，99 college students between the ages of 18 and 30 each spent an hour on a computer，trying to get through a virtual maze（迷宫）．The maze was a different place each time they tired-making it even more difficult．They were also told to find a particular picture of a tree and remember where it was．
   For the first 90 minutes of a five-hour break，half of the participants stayed awake and an half were told to take a short nap．Participants who stayed awake were asked to describe their thoughts．Participants who took a nap were asked about their dreams after sleeping-and they were awakened within a minute of sleeping to describe their dreams．Stickgold，a neuroscientist（神经科学家），wanted to know what people were dreaming about when their eyes weren't moving during sleep．
   Four of the 50 people who slept said their dreams were connected to the maze．Some dreamed about the music that had been playing when they were working；Others said they dreamed about seeing people in the maze．When these four people tried the computer maze again，they were able to find the tree faster than before their naps．
   Stickgold suggests the dream itself doesn't help a person learn-it's the other way around．He suspects that the dream was caused by the brain processes associated with learning．
   All four of the people who dreamed about the task had done poorly the first time，which makes Stickgold wonder if the dreamow up when a person finds a new task particularly difficult．People who had other dreams，or people who didn't take a nap，didn't show the same improvement．

（1）After having a short nap，participants of the experiment were asked to       ．
A．stay in a．different place in the maze．
B．design a virtual maze which is difficult to get through．
C．try to remember something about their dreams
D．get through a virtual maze on a computer from the same place
（2）What can we learn from the text？
A．Participants who took a nap were required to express their thoughts．
B．Some dreams may encourage people to invent something new．
C．Participants who dreamed about films could finish the task more easily．
D．Participants whose dreams had something to do with the maze could find the tree faster．
（3）According to Stickgold，       ．
A．every person may dream about what they learned
B．people's brain processes may still be connected with their learning in their dreams
C．once people's eyes stop moving，they are sure to dream about something
D．no matter how fantastical or boring，dreams are connected with people's life
（4）What is the best title for this text？

   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.

（1）Why did Kurtis Baute stay in the tent for only 15 hours？
A．The tent is too small for him to stay too long.
B．The environment in the tent is dangerous for him.
C．CO₂ in the tent couldn't be changed into oxygen.
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.
B．Surviving in the tent.
C．The set danger point.
D．Making people know the use of plants.

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.

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.

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．

（1）Which of the following is most likely to lead to less groundwater？
A．Using river water．
B．Throwing batteries away．
C．Paving parking lots．
D．Throwing rubbish into lakes．
（2）What can be inferred from the text？
A．All water shortages are due to human behavior．
B．It takes a lot of effort to meet our water needs．
C．There is much we can do to reduce family size．
D．The average family in America makes proper use of water．

205227. （2021•长安区一中•高二上期末） Captured（捕获的）carbon dioxide（CO₂）could be used to extract（提炼）useful metals（金属）from recycled technology such as smartphone batteries rather than just being buried underground.The technique could help make it more economical to capture the greenhouse gas before it enters the atmosphere.
   "If you also extract metals by filling CO₂，you add value to a process that is known to be costly，" says Julien Leclaire at the University of Lyon，France.
   CO₂ is the main cause of modern climate change，so many people have attempted to develop technologies to capture it when it comes from power plants and other major sources.The gas can then be stored underground.The problem is that such carbon capture and storage（CCS）is expensive."No one wants to pay the price for it，" says Leclaire.
   To make CCS more appealing，Leclaire's team has found a use for the gas.
   His team collected CO₂ from a car gas，cooledit，then pumped it into a mix of chemicals.
   The CO₂combined with the mix to make many molecules（分子）of variouapes and sizes.
   The team found that this process could sort out mixtures of metals，because one metal would dissolve（溶解）in the liquid while another would form a solid.In a series of experiments，they successfully separated three kinds of metals-all of which are used in batteries，smart phones and computers.
   If the process can be widely used，it could be a more environmentally friendly way to recycle batteries and other electrical equipment，says Leclaire.This is normally done using highly reactive chemicals，which are potentially polluting.Replacing them with CO₂ should lead to a much lower environmental pollution，he says.
   Other researchers and companies are trying to change captured CO₂ into useful materials like plastics，which are normally produced from petrol，but this is chemically difficult.Leclaire says his approach is more inline with how CO₂ behaves naturally."Instead of copying what we know how to do better and cheaper with oil，let's find things you can only do with CO₂，" he says.

（1）What can we learn from the first paragraph？
A．Extracting useful metals from recycled technology is widely used now.
B．Useful metals in the atmosphere are used to make smart phone batteries.
C．Abandoned smart phone batteries may have been buried underground before.
D．The greenhouse gas CO₂ could be cleaned up after entering the atmosphere.
（2）Why are many people attempting to capture CO₂？
A．CO₂ is the main cause of modern climate change.
B．CO₂ can be used to recycle many resources.
C．Captured CO₂ can be changed to useful gas.
D．CO₂ is harmful to people's health.
（3）What benefit could Leclaire's team's approach bring？
A．It could end the use of plastics.
B．It could reduce environmental pollution.
C．It could make more metals available to humans.
D．It could help reduce the cost of battery production.
（4）What is the best title for the text？
A．The Ways to Make Smart phone Batteries
B．The Reason for Capturing Greenhouse Gas
C．Collecting CO₂ Is Starting to Make New Progress
D．Captured CO₂ Could Be Used to Help Recycle Useful Metals
