高考英语阅读理解复习-科技类20篇(含解析)

科技类词汇对应阅读passage1A snake﹣robot designer，a technologist，an extradimensional physicist and a journalist walk into a room.The journalist turns to the crowd and asks：Should we build houses on the ocean？Like a think﹣tank panel，members of the team dream up far﹣out answers to the crucial problem，such as self﹣driving housing units that could park on top of one another in the coastal city center.The setting is X，the enterprise which considers more than100ideas each year，in areas ranging from clean energy to artificial intelligence.Although only a tiny percentage become"projects"with far﹣reaching creativity，these projects exist，ultimately，to change the world，like Waymo，the biggest self﹣driving﹣car company.In the past60years，something strange has happened.As the academic study of creativity has thrived （蓬勃发展），the label innovation may have covered every tiny change of a soda can or a toothpaste flavor，but the rate of productivity growth has been mostly declining since the1970s.John Fernald，an economist，points out that the notable exception to the post﹣1970decline in productivity occurred when businesses throughout the economy finally figured out the breakthrough technology﹣information technology.John Fernald says，"It's possible that productivity took off，because we picked all the low﹣hanging fruit from the IT wave."Actually，the world economy continues to harvest the benefits of IT.But where will the next technology shock come from？Breakthrough technology results from two distinct activities﹣invention and innovation.Invention is typically the work of scientists and researchers in labs，while innovation is an invention put to commercial use.Seldom do the two activities occur successfully under the same roof.They tend to thrive in opposite conditions；while competition and consumer choice encourage innovation，invention has historically progressed in labs that are protected from the pressure to generate profit.Allowing well﹣funded and diverse teams to try to solve big problems is what gave us the computer and the Internet.Today，we fail to give attention to planting the seeds of this kind of ambitious research，while complaining about the harvest."Companies are really good at combining existing breakthroughs in ways that consumers like.But the breakthroughs come from patient and curious scientists，not the rush to market，"says Jon Gertner，the author of The Idea Factory."Technology is a tall tree，"John Fernald said."But planting the seeds of invention and harvesting the fruit of innovation are entirely distinct skills，often mastered by different organizations and separated by manyyears."As for me，both of them are essential for technology，although they are relatively independent.I don't think X is a planter or a harvester，actually.It is like building taller ladders.Nobody knows for sure what，if anything，the employees at such enterprises are going to find up on those ladders.But they're reaching.At least someone is.（1）What is the main purpose of the first two paragraphs？A．To present the process of group discussion.B．To illustrate X's worry about big problems.C．To reveal the importance of the crazy ideas.D．To stress the varied backgrounds of the team.（2）What can we learn from the passage？A．Breakthroughs must stand the test of the market.B．Innovation on necessities can promote productivity.C．Invention develops slowly under the pressure of profit.D．The harvest of innovation lies in some ambitious research.（3）Regarding John Fernald's view on technology，the author is.A．supportiveB．cautiousC．uncertainD．critical（4）What can be inferred about X from the passage？A．It will focus on innovation.B．It will have its outcome soon.C．It may give in to its fruitless reality.D．It may bring an encouraging outlook.【分析】这是一篇说明文。

高考真题阅读理解科技说明文汇编（科技类说明文是阅读中的难点，学生容易失分，有很大的区分度。

因此，开展有针对性的训练很有必要，本汇编精选近年高考真题，以求把握难度，总结规律，达到事半功倍的效果，）（2020全国卷I ）话题：植物新科技DThe connection between people and plants has long been the subject of scientific research. Recent studies have found positive effects. A study conducted in Youngstown，Ohio，for example, discovered that greener areas of the city experienced less crime. In another，employees were shown to be 15% more productive when their workplaces were decorated with houseplants.The engineers at the Massachusetts Institute of Technology（MIT）have taken it a step further changing the actual composition of plants in order to get them to perform diverse，even unusual functions. These include plants that have sensors printed onto their leaves to show whe n they’re short of water and a plant that can detect harmful chemicals in groundwater. ＂We’re thinking about how we can engineer plants to replace functions of the things that we use every day,＂explained Michael Strano, a professor of chemical engineering at MIT.One of his latest projects has been to make plants grow（发光）in experiments using some common vegetables. Strano’s team found that they could create a faint light for three-and-a-half hours. The light，about one-thousandth of the amount needed to read by，is just a start. The technology, Strano said, could one day be used to light the rooms or even to turn tree into self-powered street lamps.in the future，the team hopes to develop a version of the technology that can be sprayed onto plant leaves in a one-off treatment that would last the plant’s lifetime. The engineers are also trying to develop an on and off＂switch＂where the glow would fade when exposed to daylight.Lighting accounts for about 7% of the total electricity consumed in the US. Since lighting is often far removed from the power source（电源）—such as the distance from a power plant to street lamps on a remote highway-a lot of energy is lost during transmission（传输）.Glowing plants could reduce this distance and therefore help save energy.32. What is the first paragraph mainly about?A. A new study of different plants.B. A big fall in crime rates.C. Employees from various workplaces.D. Benefits from green plants.33. What is the function of the sensors printed on plant leaves by MIT engineer?A. To detect plants’ lack of waterB. To change compositions of plantsC. To make the life of plants longer.D. To test chemicals in plants.34. What can we expect of the glowing plants in the future?A. They will speed up energy production.B. They may transmit electricity to the home.C. They might help reduce energy consumption.D. They could take the place of power plants.35. Which of the following can be the best title for the text?A. Can we grow more glowing plants?B. How do we live with glowing plants?C. Could glowing plants replace lamps?D. How are glowing plants made pollution-free?（2019全国卷I ）话题：利用生物信息进行身份识别CAs data and identity theft becomes more and more common, the market is growing for biometric（生物测量）technologies—like fingerprint scans—to keep others out of private e-spaces. At present, these technologies are still expensive, though.Researchers from Georgia Tech say that they have come up with a low-cost device（装置）that gets around this problem: a smart keyboard. This smart keyboard precisely measures the cadence （节奏）with which one types and the pressure fingers apply to each key. The keyboard couldoffer a strong layer of security by analyzing things like the force of a user’s typing and the time between key presses. These patterns are unique to each person. Thus, the keyboard can determine people’s identities, and by extension, whether they should be given access to the computer it’s connected to —regardless of whether someone gets the password right.It also doesn’t require a new type of technology that people aren’t already familiar with. Everybody uses a keyboard and everybody types differently.In a study describing the technology, the researchers had 100 volunteers type the word ＂touch＂four times using the smart keyboard. Data collected from the device could be used to recognize different participants based on how they typed, with very low error rates. The researchers say that the keyboard should be pretty straightforward to commercialize and is mostly made of inexpensive, plastic-like parts. The team hopes to make it to market in the near future.28. Why do the researchers develop the smart keyboard?A. To reduce pressure on keys.B. To improve accuracy in typingC. To replace the password system.D. To cut the cost of e-space protection.29. What makes the invention of the smart keyboard possible?A. Computers are much easier to operate.B. Fingerprint scanning techniques develop fast.C. Typing patterns vary from person to person.D. Data security measures are guaranteed.30. What do the researchers expect of the smart keyboard?A. It’ll be environment-friendly.B. It’ll reach consumers soon.C. It’ll be made of plastics.D. It’ll help speed up typing.31. Where is this text most likely from?A. A diary.B. A guidebookC. A novel.D. A magazine.（2018全国卷I）话题：不同电器设备耗电研究DWe may think we’re a culture that gets rid of our worn technology at the first sight of something shiny and new, but a new study shows that we keep using our old devices (装置) well after they go out of style. That’s bad news for the environment – and our wallets – as these outdated devices consume much more energy than the newer ones that do the same things.To figure out how much power these devices are using, Callie Babbitt and her colleagues at the Rochester Institute of Technology in New York tracked the environmental costs for each product throughout its life – from when its minerals are mined to when we stop using the device. This method provided a readout for how home energy use has evolved since the early 1990s. Devices were grouped by generation. Desktop computers, basic mobile phones, and box-set TVs defined 1992. Digital cameras arrived on the scene in 1997. And MP3 players, smart phones, and LCD TVs entered homes in 2002, before tablets and e-readers showed up in 2007.As we accumulated more devices, however, we didn’t throw out our old ones. “The living-room television is replaced and gets planted in the kids’ room, and suddenly one day, you have a TV in every room of the house,” said one researcher. The average number of electronic devices rose from four per household in 1992 to 13 in 2007. We’re not just keeping these old devices – we continue to use them. According to the analysis of Babbitt’s team, old desktop monitors and box TVs with cathode ray tubes are the worst devices with their energy consumption and contribution to greenhouse gas emissions (排放) more than doubling during the 1992 to 2007 window.So what’s the solution (解决方案)? The team’s data only went up to 2007, but the researchers also explored what would happen if consumers replaced old products with new electronics that serve more than one function, such as a tablet for word processing and TV viewing. They found that more on-demand entertainment viewing on tablets instead of TVs and desktop computers could cut energy consumption by 44%.32. What does the author think of new devices?A. They are environment-friendly.B. They are no better than the old.C. They cost more to use at home.D. They go out of style quickly.33. Why did Babbitt’s team conduct the research?A. To reduce the cost of minerals.B. To test the life cycle of a product.C. To update consumers on new technology.D. To find out electricity consumption of the devices.34. Which of the following uses the least energy?A. The box-set TV.B. The tablet.C. The LCD TV.D. The desktop computer.35. What does the text suggest people do about old electronic devices?A. Stop using them.B. Take them apart.C. Upgrade them.D. Recycle them.(2020全国卷II) 话题：海狸鼠毛皮的利用问题CWhen you were trying to figure out what to buy for the environmentalist on your holiday list, fur probably didn’t cross your mind. But some ecologists and fashion (时装）enthusiasts are tryingto bring back the market for fur made from nutria(海狸鼠).Unusual fashion shows in New Orleans and Brooklyn have（showcased）nutria fur made into clothes in different styles. “It sounds crazy to talk about guilt-free fur-unless you understand that the nutria are destroying vast wetlands every year”,says Cree McCree, project director of Righteous Fur.Scientists in Louisiana were so concerned that they decided to pay hunters $5 a tail. Some of the fur ends up in the fashion shows like the one in Brooklyn last month.Nutria were brought there from Argentina by fur farmers and let go into the wild. “The ecosystem down there can’t handle this non-native species（物种）.It’s destroying the environment. It’s them or us." says Michael Massimi, an expert in this field.The fur trade kept nutria check for decades，but when the market for nutria collapsed in the late 1980s，the cat-sized animals multiplied like crazy.Biologist Edmond Mouton runs the nutria control program for Louisiana. He s ays it’s not easy to convince people that nutria fur is green, but he has no doubt about it. Hunters bring in more than 300,000 nutria tails a year, so part of Mouton’s job these days is trying to promote fur.Then there’s Righteous Fur and its unusual fashion. Morgan says，“To give people a guilt-free option that they can wear without someone throwing paint on them—1 think that’s going to be a massive thing, at least here in New York.” Designer Jennifer Anderson admits it took her a while to come around to the opinion that using nutria fur for her creations is morally acceptable. She trying to come up with a lable to attach to nutria fashions to show it is eco-friendly.28. What is the purpose of the fashion shows in New Orleans and Brooklyn?A. To promote guilt-free fur.B. To expand the fashion market.C. To introduce a new brand.D. To celebrate a winter holiday.29. Why are scientists concerned about nutria?A. Nutria damage the ecosystem seriously.B. Nutria are an endangered species.C. Nutria hurt local cat-sized animals.D. Nutria are illegally hunted.30. What does the underlined word “collapsed” in paragraph 5 probably mean?A. Boomed.B. Became mature.C. Remained stable.D. Crashed.31. What can we infer abouf wearing fur in New York according to Morgan?A. It’s formal.B. It’s risky.C. It’s harmful.D. It’s traditional.（2017全国卷I）话题：户外自制蒸馏器DA buld-it-yourself solar still（蒸馏器）is one of the best ways to obtain drinking water in areas where the liquid is not readily available. Developed by two doctors in the U.S. Department of Agriculture, it’s an excellent water collector. Unfortunately, you must carry the necessary equipment with you, since it’s all but impossible to find natural substitutes. The only components required, though, are a 5＇ 5＇sheet of clear or slightly milky plastic, six feet of plastic tube, and a container—perhaps just a drinking cup —to catch the water. These pieces can be folded into a neat little pack and fastened on your belt.To construct a working still, use a sharp stick or rock to dig a hole four feet across and three feet deep. Try to make the hole in a damp area to increase the water catcher’s productivity. Place your cup in the deepest part of the hole. Then lay the tube in place so that one end rests all the way in the cup and the rest of the line runs up —and out —the side of the hole.Next, cover the hole with the plastic sheet, securing the edges of the plastic with dirt and weighting the sheet’s center down with a rock. The plastic should now form a cone(圆锥体) with 45-degree-angled sides. The low point of the sheet must be centered directly over, and no more than three inches above, the cup.The solar still works by creating a greenhouse under the plastic. Ground water evaporates (蒸发) and collects on the sheet until small drops of water form, run down the material and fall off into the cup. When the container is full, you can suck the refreshment zxxk out through the tube, and won’t have to break down the still every time you need a drink.32. What do we know about the solar still equipment from the first paragraph?A. It’s delicate.B. It’s expensive.C. It’s complex.D. It’s portable.33. What does the underlined phrase “the water catcher” in paragraph 2 refer to?A. The tube.B. The still.C. The hole.D. The cup.34. What’s the last step of constructing a working solar still?A. Dig a hole of a certain size.B. Put the cup in place.C. Weight the sheet’s center down.D. Cover the hole with the plastic sheet.35. When a solar still works, drops of water come into the cup form .A. the plastic tubeB. outside the holeC. the open airD. beneath the sheet（2016全国卷I）话题: 不同文化背景下的沉默内涵The meaning of silence varies among cultural groups. Silences may be thoughtful, or they may be empty when a person has nothing to say.A silence in a conversation may also show stubbornness, or worry. Silen ce may be viewed by some cultural groups as extremely uncomfortable; therefore attempts may be made to fill every gapwith conversation. Persons in other cultural groups value silence and vie w it as necessary for understanding a person's needs.Many Native Americans value silence and feel it is a basic part of co mmunicating among people, just as some traditional Chinese and Thai persons do. Therefore, when a person from one of these cultures is spea king and suddenly stops, what maybe implied(暗示) is that the person wants the listener to consider what has been said before continuing. In these cultures, silence is a call for reflection.Other cultures may use silence in other ways, particularly when dealing with conflicts among people or in relationships of people with different amounts of power. For example, Russian, French, and Spanish persons may use silence to show agreement between parties about the topic under discussion. However, Mexicans may use silence when instructions are given by a person inauthority rather than be rude to that person by arguing with him or her. In still another use, persons in Asian cultures may view silence as a sign of respect, particularly to an elder or a person in authority.Nurses and other care-givers need to be aware of the possible meanings of silence when they come across the personal anxiety their patients may be experiencing. Nurses should recognize their own personal and cultural construction of silence so that a patient’s silence is not interrupted too early or allowed to go on unnecessarily. A nurse who understands the healing(治愈) value of silence can use this understanding to assist in the care of patients from their own and from other cultures.32.What does the author say about silence in conversations?A.It implies anger.B.It promotes friendship.C.It is culture-specific.D.It is content-based.33.Which of the following people might regard silence as a call for careful thought?A.The Chinese.B.The French.C.The Mexicans.D.The Russians.34.What does the author advise nurses to do about silence?A.Let it continue as the patient pleases.B.Break it while treating patients.C.Evaluate its harm to patients.D.Make use of its healing effects.35.What may be the best title for the text?A.Sound and SilenceB.What It Means to Be SilentC.Silence to Native AmericansD.Speech Is Silver; Silence Is Gold参考答案：DACCDCBAADBAAADBDBCDCADB。

2025届高考英语复习阅读理解：01人与社会之科学与技术(含解析)

01 人与社会--科学与技术Passage 1（2024高三上·全国·专题练习）Natural disasters like earthquakes and storms can pull down buildings easily. It's difficult for the search and rescue teams (搜救队) to find those who are trapped (陷于困境) in the fallen buildings.But an unlikely assistant, mice, is being trained up to help out. The project started by Belgian APOPO, is planning to tie tiny, high-tech backpacks to mice to help search for survivors (幸存者).“Mice like to explore —and that is key for search and rescue.” said Donna Kean, a scientist and leader of the project.“ Besides, their small size and excellent sense of smell make them perfect for locating (定位) things in small spaces.”The mice are being trained in a basic environment at present. They must first locate the target (目标) person in an empty room, pull a switch that starts an alarm on their clothes, and then return home, where they are given a treat.For the next part of training, Kean said the team would create “disaster-similar areas”. Once the mice are confident in these areas, the project will move to Turkey for further preparation in more real environments. If that goes well, the mice would probably enter real- life situations.The mice are still in the early progress of training. And APOPO is working with the Eindhoven University of Technology to develop a backpack with a video camera, a two-way microphone, and a locating tool to help communicate with survivors. “Together with the backpack and the training, the mice are very useful for search and rescue,” said Kean. “Even if our mice find just one survivor, we would be happy toknow they have made a difference somewhere.”1．According to the passage, What’s the reason for mice to be chosen for search and rescue① Because their nature of exploring.② Because their small sizes.③ Because their ability to smell something.④ Because their perfect eyesight in the dark.A．①②③ B．①③④ C．②③④ D．①②④2．Which paragraph tells how the mice are trainedA．Paragraph 1. B．Paragraph 2.C．Paragraph 3. D．Paragraph 4.3．What can we learn from the passageA．Donna Kean is a survivor in an earthquake.B．The mice are being trained in real-life situations.C．APOPO scientists haven’t invented the high-tech backpack.D．The mice are often given a treat before they complete the task.4．What does Donna Kean think of the projectA．Nervous. B．Interesting.C．Hopeful. D．Impossible.【答案】1．A 2．D 3．C 4．C【导语】这是一篇说明文。

2024-2025学年七年级新教材英语阅读理解练习附答案

2024-2025学年七年级英语新教材阅读理解（附答案）（1）科技探索类阅读A mysterious visitorA In October 2017，astronomers in Hawaii saw something surprising. Astrange object was moving through the solar system. They had seen many asteroid s before ,but this was something different. It was long and thin---like a cucumber. The object’s speed and direction also showed something surprising .This was an interstellar object ---the first ever seen .B The object was named ’Oumuamua---Hawaiian for “vistor fromafar,”Nobody is sure exactly wha t it is . The simplest idea is that ’Oumuamua is a strangely shaped piece of rock. Perhaps it was knocked out of a far -off star system. However ,astronomers saw that its speed increase d after passing the sun. Some scientists therefore suggest a different theory.C“’Oumuamua could be a piece of alien technology,”says Professor Abranham Loeb from Harvard University. Loeb believes this could explain the object’s long , thin shape, and also its change in speed .Maybe ’Oumuamua was a spaceship that came to explore our solar system.” All possibilities should be consider ed,”says Loeb.D’Oumuamua can no longer be seen from Earth. But astronomers continue to study the information they got from it . It is still not clear if the object was a large rock, or somet hing else altogether .’Oumuamua will likely be a mystery for many years to come.Choose the best answer for each question.1.What is the reading mainly about?（）a.new technology to help scientists find asteroidsb.the largest asteroid ever seen by scientistsc.a myterious object that passed by Earth2.What did scientists learn from studying ’Oumuamua’s speed anddirection?（）a.It came from another star system.b.It was possible it could hit the Earth .c.It was an asteroid.3.What is NOT given as a reason why ’Oum uamua could be an alienspaceship ?（）a.the object’s size and shapeb.the object’s change in speedc.the object’s color4.In paragraph C , what does considered mean?（）a.explained in detailb.thought about carefullyc.chosen from a list5.According to the in fographic on page 10, when was ’Oumuamua firstseen from Earth?（）a.as it entered the inner solar systemb.just before it passed the sunc.after it passed the sunAnswers:1.C2. A3. C4. B5. B（2）历史文化类阅读The Lost City Of AtlantisA Most people have heard the story of the lost city of Atlantis . But is anypart of the story true ?B Over two thousand years ago ,the Greek writer Plato wrote aboutAtlantis , an island in the Atlantic Ocean . The island’s people were very rich . They built a big city with many great buildings . But the people became greedy---they had many things ,but they still wanted more . So the gods became angry. Earthquakes and large waves began to strike the island. Finally, Atlantis sank into the sea.C Many explorer s have looked for Atlantis . In 2004, explorer RobertSarmast reported finding the remains of a city under the sea near Cyprus. However , Sarmast and other scientists later realized the structures he found under the sea were natural ,not man-made .Mark Adams ,author of the 2016 book Meet Me in Atlantis believe s the citywas in Morocco. Plato wrote about red and black stone circle s around the city. Adams found similar red and black stones in the desert there ,very near the Atlantis Ocean.D Most people ,however ,think Atlantis is simply a story . The purpose ofthe story may be to teach people not to be greedy. Richard Ellis also wrote a book about Atlantis in 1999. He says “there is not a piece of solid evidence” for a real Atlantis.E So was the island real or not ? We only know one thing : The mystery ofAtlantis will be with us for a long time.Choose the best answer for each question.1.What could be another title for the reading ?（）A.Atlantis SinksB.Is Atlantis Real?C.I Found Atlantis!D.A Big City.2.What happened after Robert Sarmast said he found Atlantis?（）A.He wrote a book about his findings.B.Richard Ellis said that Atlantis was not real.C.He found out the structure were not man-made.D.He said the city under the sea near Japan.3.What is the main idea of paragraph C ?（）A.Scientists believe Atlantis is just a story.B.Explores found a city under the sea near Morocco.C.People have looked for Atlantis ,but no one has found.D.Plato wrote about red and black stone circles around the city.4.Why does Mark Adams believe Atlantis could be in Morocco.（）A.He discovered the remains of houses in the ocean there.B.He found colored stones similar to ones described by Plato.C.He found a map that showed Atlantis’s location in the Atlantic Ocean.D.He found the city.5.In paragraph D ,which sentence is closest in meaning to “there is not apiece of solid evidence” for a real Atlantis?（）A.There is only one reason to believe the Atlantis story is true.B.The story of Atlantis is made up of many small pieces.C.There is nothing to make us believe the Atlantis story is true.D.Atlantis is simply a story.Answers:1.B2.C3.C4.B5.C（3）环境科学类阅读理解Read the passageOne of Earth’s closed systems is the water system . It is closed because although the water may take different forms--ice ,water ,vapor--the same amount is always present . A lot is tied up in ice at the poles , and much of itis salty because it is in the ocean , but altogether ,we have the same amount of water now as we did when the Earth was formed . The water cycle is how that water moves around. It evaporates when the Sun heats up lakes or rivers and turns into water vapor--just like the steam from a kettle. The vapor rises , but when it meets colder air high up ,it condenses or turns back to water . It falls as rain or snow ,or even as fog ,and the water returns to the Earth , although each molecule may be thousands of miles from where it started.1.What is the main idea of this passage?（）A.The amount of water on Earth is finite.B.Water is present in three different forms.C.The water we drink has been used many times before.D.Nature is a great recycler.2.The author compares the heat under a kettle to ______.A.water vaporB.steamC.the sunD.evaporation3.Which suffix turns effect into adjective?（）A.-ableB.-lessC.-iveD.-ious答案1.

五年级科技创新英语阅读理解20题

五年级科技创新英语阅读理解20题1<背景文章>Smartphones have become an important part of our lives. In the past few years, smartphones have developed rapidly. They are not only used for making phone calls and sending text messages, but also for taking pictures, listening to music, playing games and surfing the Internet.Smartphones are very convenient. We can use them to communicate with our friends and family at any time. We can also use them to get information quickly. For example, we can use them to look up the meaning of a word, find the way to a place or check the weather forecast.However, smartphones also have some disadvantages. For example, some people spend too much time on their smartphones and ignore their real lives. Some people also use their smartphones to play games or watch videos for a long time, which is bad for their eyes.In conclusion, smartphones have both advantages and disadvantages. We should use them properly and not let them control our lives.1. Smartphones can be used for many things except ______.A. making phone callsB. doing homeworkC. taking picturesD. listening to music答案：B。
