Tablets are really useful devices, but their big screens always make them as a burden to carry around without a bag. Wouldn't it be great if there were a phone with the powers of a tablet that could be folded up and fit neatly into the hand?Now something like a tablet-shaped but foldable phone is about to become available. In February, South Korean electronics company Samsung and China's Huawei both launched foldable phones, the Galaxy Fold and Huawei Mate X respectively. Mobile phone use has entered the "foldable future", The Verge noted.The technology could change our lives in significant ways. These devices, due to their bendable screens, give us the larger screens we want. Meanwhile, they still fit easily into the pocket. As USA Today noted, they're "the combination of a small tablet and smartphone, all in a single device".The technology could change other devices, too. For example, we could make TVs that stick to walls like posters, or fold up easily to hide away in drawers. In crowded modem cities, they will help us to maximize available space.In a keynote address, Samsung's senior vice president of mobile product marketing, Justin Denison, called the foldable screen "the foundation for the smartphone of tomorrow". "It's a blank canvas (画布) for us to do something beautiful together." he said.So is there nothing to stand in the way of the foldable future? According to tech news website Android Authority, the necessary displays were difficult to produce. In 2012, nine out of every 10 OLED (二极管) screens produced were imperfect. Today, that 10 percent rate has been improved to between 50 and 90 percent. However, at present these foldable devices are expensive. For example, the price of Huawei Mate X is 17,500 RMB. That's a price that few people will be able to afford.But if the foldable device isn't going to change the world overnight, there is no doubt that it is coming. Patrick Moorhead, an industry analyst told The Verge, "Few are debating if foldable or rollable mobile displays are the future of smartphones; the only question is when and by whom."（1）What can be the best title for the text?A. Screen devices on the market.B. Foldable age is arriving.C. Possible powers of a tablet.D. Foldable screens are imperfect.（2）What can we learn from Justin Denison's words?A. The foldable screen has great potential.B. The Galaxy Fold still has many problems.C. The production of foldable phones will soon increase.D. Companies need to work together to develop foldable phone.（3）What is the problem with foldable phones at the moment?A. They are easy to break.B. They are inconvenient to carry.C. They are not as useful as expected.D. They are unaffordable for most families.（4）What is the author's attitude toward the future of the foldable screen?A. Worried.B. Cautious.C. Positive.D. Unconcerned.【答案】（1）B（2）A（3）D（4）C【解析】【分析】本文是一篇说明文，介绍了“可折叠手机的时代即将到来。

2012 年全国高考英语试题阅读理解分类汇编之科技说明文类（精校word版有答案解析）point guard, or numbers person. The fixed mind-set believes it’s sure to succeed without much effort and regards failure as personal shame. When things get difficult, it’s quick to blame, lie, and even stay away from future difficulties.On the other hand, a growth mind-set believes that no talent is entirely heaven-sent and that effort and learning make everything possible. Because the ego (自尊) isn’t on the line as much, the growth mind-set sees failure as a chance rather than shame. When faced with a difficulty, it’s quick to rethink, change and try again. In fact, it enjoys this experience.We are all born with growth mind-sets. (Otherwise, we wouldn’t be able to live in the world.) But parents, teachers, and instructors often push us into fixed mind-sets by encouraging certain actions and misdirecting praise. Dweck’s book, Mind-set: The New Psychology of Success, and online instructional program explain this in depth. But she says there are many little things you can start doing today to make sure that your children, grandchildren and even you are never defeated by failure.【文章大意】本文是一篇科学调查报告。

2023届高考英语二轮阅读理解专题之科普知识类说明文（含参考答案、核心词汇背诵默写版、参考译文）A篇Every person yawns. So do many other vertebrate (有脊椎的) animals, including snakes, dogs, cats, sharks, and chimpanzees. While yawning is contagious (会传染的), not everyone catches a yawn. Around 60-70% of people yawn if they see another person yawn in real life or in a photo or even read about yawning. Contagious yawning also occurs in animals, but it doesn’t necessarily work the same way as in people.Scientists have proposed many theories for why we catch yawns. Probably the most popular theory is that yawning serves as a form of nonverbal communication. Catching a yawn shows you’re accustomed to a person’s emotions. Scientific evidence comes from a 2010 study at the University of Connecticut, which concluded yawning does not become contagious until a child is about four years old when empathy (共情) skills develop. In the study, children with autism, who may have impaired empathy development, caught yawns less often than their peers.Studying contagious yawning in other animals may provide clues to how people catch yawns. Contagious yawning in animals may serve as a means of communication. Siamese fighting fish yawn when they see their mirror image or another fighting fish, generally just prior to an attack.Contagious yawning is linked to temperature, in both animals and people. Most scientists speculate it is a thermoregulatory behavior, while some researchers believe it is used to communicate a potential threat or stressful situation. A 2010 study of budgerigars (虎皮鹦鹉) found that yawning increased as temperature was raised near body temperature.People commonly yawn when tired or bored. Similar behavior is seen in animals. One study found the brain temperature in sleep deprived rats was higher than their core temperature. Yawning reduced brain temperature, possibly improving brainfunction. Researchers will do further study on this.1.What can we learn about yawning from Paragraph 1?A．All animals yawn.B．Reading about yawning may make a person yawn.C．Only vertebrate animals yawn.D．Yawning works the same for human and animals.2. Why does the author mention children with autism in Paragraph 2?A．To prove a theory.B．To define a conceptC．To develop the theme.D．To provide the background.3. Siamese fighting fish yawn to ________.A．show kindness.B．find a partner.C．give a threat.D．escape from danger.4. What can be inferred from the passage?A．More research in yawning will be carried out in the future. B．Temperature is not a factor concerning yawning.C．The secret to yawing has been worked out.D．Yawning can improve brain function greatly.B篇Using the power of artificial intelligence (AI) , scientists have revealed new insights into the creation and destruction of mass extinction. Contrary to conventional knowledge, their study suggests that larger extinctions are not always a form of "creative destruction" that allows new organisms (生物体) to radiate and evolve. Instead, it suggests that mass extinction is rarely associated with new species of radiation.Dr. Hoyal Cuthill, the lead study author from the University of Essex in the UK and the Tokyo Institute of Technology, said in a statement, “Some of the mostchallenging things to understand the history of life are the vast timelines involved and the number of species. New machine learning applications can help us understand this information in human-readable form. This means that we can, so to speak, hold the evolution of half a billion years in the palm of our hand and gain new insights from what we see.”They concluded that mass extinction and later radiation were not connected as previously thought. Within 5 percent of the most significant periods of disruption (中断), AI detected “big five” mass extinctions, seven more mass extinctions, two mass extinction-radiation events, and 15 mass radiations. Most importantly, it discovers that massive radiation and extinction rarely occurred with each other, changing the view that greater extinction leads to a kind of deep cycle-like species radiation of nature. It appears that larger extinctions are certainly not the engine of evolutionary radiation. Take the Cambrian eruption for example and it was about 41 million years ago when a large group of animals first appeared on the record of the first fossil record and the dawn of a high mobile animal equipped with modern physical features.This new study found that a handful of other notable explosions of biodiversity, including the Cambrian eruption, usually occurred at a time when they were largely isolated (隔离) from extinction. Dr. Nicholas Guttenberg, a study co-author from the Tokyo Institute of Technology explained, “Ecosystems are dynamic and you don't need anything to exist to allow something new to appear.”1. What does the first paragraph serve as?A. An explanation of artificial intelligence.B. A background of researchers' study.C. The reasons for creative destruction.D. The result of researchers' new study.2. What can we infer from Dr. Hoyal Cuthill's words?A. AI contributes a lot to the study of evolution.B. Understanding the history of life is very difficult.C. New AI machines learn applications better.D. Biological evolution can be controlled easily.3. What is the researchers' discovery?A. Mass extinction is unlikely to cause evolutionary radiation.B. The first animal with modern features occurred during eruption.C. The volcanic eruption led to a mass extinction and radiation.D. The idea of deep cycle-like species radiation has turned out true.4. What is the text mainly about?A. New processes of biological evolution.B. New view of radiation from natural species.C. New understanding of mass extinction.D. New outbreaks of biological populations.C篇Midway through The Matrix, Cypher feasts on an enormous steak, well aware that his reality is not real, part of a digital program telling his brain that the steak is a construction and that it is “juicy and delicious.” Two decades after the movie made its first appearance, something unexpected arises: The future of reality will not only be virtual but also synthetic (合成的). Cypher’s future meal will be a physical one, synthesized from animal cells.And the synthesis goes beyond dinner. Starting with components from the natural world, scientists are learning to engineer microorganisms and build biocomputing systems. However, biology has a tendency to evolve in unexpected ways.Synthesized meat is one case in point. The driving forces behind the meat movement are practical. It has been estimated that cultured (培育的) meat would require 7 to 45 percent less energy and produce 78 to 96 percent less greenhouse gas than conventional animals farmed for consumption. But once we’re able to synthesize meat, theoretically, we’ll have the capability to culture meat from any animal, even those we’d never consider eating today, like dolphins or chimpanzees, which will pose a new regulatory challenge for us.Using synthetic biology, we can even edit and rewrite life, the technology of which are already in use. In 2021, scientists in some countries announced they had grown monkey embryos injected with human stem cells. Here comes the situationworth considering: such a monkey-human hybrid will demonstrate qualities that are somewhere between humans, on which experimentation isn’t allowed, and animals, which are often raised specifically for research. How will we decide when an animal becomes too human?Depending on where you stand, the synthetic realities land somewhere between “really exciting” and “critically concerning.” As individuals, we undertake a shared responsibility to make good choices about this coming synthetic technology.1.What do we know about Cypher’s steak in the movie?A．It is anything but appetizing.B．It is enjoyed in a virtual world.C．It is synthesized from animal cell.D．It is a construction made by himself.2. What’s the advantage of synthesized meat?A．It is more nutritious.B．It is more energy-consuming.C．It is more environment-friendly.D．It is more controllable in regulation.3. What is the author’s attitude to the experiment in Paragraph 4?A．Cautious.B．Favorable.C．Pessimistic.D．Indifferent.4. What is the purpose of the text?A．To popularize synthetic technology.B．To indicate challenges of synthetic technology.C．To stress the importance of synthetic technology.D．To introduce the development of synthetic technology.参考答案A1.B2.A3.C4.A参考答案B1.D2.A3.A4.C参考答案C1.B2.C3.A4.B1.yawn/jɔːn/v.打哈欠2.shark n.鲨鱼3.contagious/kənˈteɪdʒəs/adj.传染的4.propose v.提议- proposal n.提议5.theory n.理论6.verbal&oral adj.口头的7.be accustomed to doing sth8.impair/ɪmˈpeə(r)/v.损害，削弱9.peer n.同龄人10.clue n.线索11.serve as a means of communication充当交流的手段12.mirror image 镜像13.prior to...先于......14.speculate/ˈspekjuleɪt/v.猜测15.a potential threat/buyer/customer潜在的危险/买家/顾客16.a stressful situation17.deprive/dɪˈpraɪv/ v.剥夺，使丧失18.core n.核心，果核19.brain function大脑功能20.concerning prep.关心1.yawn/jɔːn/v._____2.shark n._____3.contagious/kənˈteɪdʒəs/adj.______4.propose v.提议- ________ n.提议5.theory n._____6._______&oral adj.口头的7.be accustomed ____(do) sth8.______/ɪmˈpeə(r)/v.损害，削弱9._____ n.同龄人10._____ n.线索11.serve as ___ means of communication充当交流的手段12.mirror image _____13.prior ___...先于......14.________/ˈspekjuleɪt/v.猜测15.a potential threat/buyer/customer潜在的_____/____/_____16.a ________(stress) situation17.________/dɪˈpraɪv/ v.剥夺，使丧失18._______ n.核心，果核19.brain function_______20.________(concern) prep.关于1.reveal v.揭露2.insight into...对......的洞悉3.destruction n.破坏4.mass extinction 大规模灭绝5.contrary to conventional knowledge和传统知识相反anism/ˈɔːɡənɪzəm/ n.生物，有机体organic/ɔːˈɡænɪk/adj.有机的7.radiate/ˈreɪdieɪt/v.流露，辐射8.evolve v.进化- evolution n.进化- evolutionary adj.进化的9.be associated with...和......有关10.timeline n.时间轴11.so to speak也就是说12.palm/pɑːm/n.手掌13.conclude- conclusion n.结论14.massive adj.大规模的15.it appears that…看来16.engine n.动力，引擎17.fossil/ˈfɒs(ə)l/n.化石18.the dawn of civilization文明的开端19.a handful of...少量的20.notable adj.显著的21.explode- explosion n.爆炸22.co- author联名作者23.ecosystem/ˈiːkəʊsɪstəm/ n.生态系统24.dynamic/daɪˈnæmɪk/adj.动态的，充满活力的1._______ v.揭露2.insight _____...对......的洞悉3.destruction n.破坏4.mass extinction ________5.contrary ____ conventional knowledge和传统知识相反anism/ˈɔːɡənɪzəm/ n.________ organic/ɔːˈɡænɪk/adj.______7.radiate/ˈreɪdieɪt/v.__________8.evolve v.进化- ________ n.进化- _________ adj.进化的9.be associated ____...和......有关10.timeline n.______11.so to speak________12._______/pɑːm/n.手掌13.conclude- ________n.结论14._______ adj.大规模的15.it appears that…看来...16_______ n.动力，引擎17.fossil/ˈfɒs(ə)l/n._____18.the _____ of civilization文明的开端19.a handful of...少量的20._______(note) adj.显著的21.explode- _______ n.爆炸22.co- author联名作者23.ecosystem/ˈiːkəʊsɪstəm/ n.________24._________/daɪˈnæmɪk/adj.动态的，充满活力的核心词汇C1.feast on ...尽情享受2.enormous/ɪˈnɔːməs/adj.巨大的3.construction/kənˈstrʌkʃn/n.建设4.juice- juicy taste- tastyponent/kəmˈpəʊnənt/n.成分6.have a tendency to do sth 趋势，倾向7.evolve- evolution - evolutionary8.in an unexpected way9.a driving force 动力10.it is estimated that…11.conventional adj.传统的12.consume- consumption n.消费13.theory- theoretical adj.理论上的14.capable- capability n.能力15.have the capability to do sth16.consider doing sth17.pose a new threat/challenge 18.edit v.编辑- editor n.编辑19.inject/ɪnˈdʒekt/ v.注射20.embryo/ˈembriəʊ/ n.胚胎21.popular- popularize v.普及22.stem cells 干细胞23.demonstrate v.展示24.hybrid/ˈhaɪbrɪd/n.混合物，杂种25.undertake a shared responsibility承担共同责任1.feast ____ ...尽情享受2.__________/ɪˈnɔːməs/adj.巨大的3._________/kənˈstrʌkʃn/n.建设4.juice-_____ taste- ______5.________/kəmˈpəʊnənt/n.成分6.have a _______ to do sth 趋势，倾向7.evolve- evolution - _________8.___ an unexpected way9.a driving force 动力10.___ is estimated that…11._________ adj.传统的12.consume- _________ n.消费13.theory- theoretical adj._____14.capable- _________ n.能力15.have the capability___(do) sth16.consider ______(do) sth17.____ a new threat/challenge 18.edit v.编辑- ______ n.编辑19._____/ɪnˈdʒekt/ v.注射20.embryo/ˈembriəʊ/ n.______21.popular- __________ v.普及22.stem cells ______23.__________ v.展示24.hybrid/ˈhaɪbrɪd/n.混合物，杂种25.undertake a ______(share) responsibility承担共同责任参考译文A每个人都会打哈欠。

专题16 科普类说明文2019高考题D【2019·全国I】We 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.

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.

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.

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。

2020高考英语全国II卷BSome parents will buy any high-tech toy if they think it will help their child, but researchers said puzzles help children with math-related skills.Psychologist Susan Levine, an expert on mathematics development in young children the University of Chicago, found children who play with puzzles between ages 2 and 4 later develop better spatial skills. Puzzle play was found to be a significant predictor of cognition(认知) after controlling for differences in parents’ income,education and the amount of parent talk, Levine said.The researchers analyzed video recordings of 53 child-parent pairs during everyday activities at home and found children who play with puzzles between 26 and 46 months of age have better spatial skills when assessed at 54 months of age.“The children who played with puzzles performed better than those who did not, on tasks that assessed their ability to rotate(旋转)and translate shapes,” Levine said in a statement.The parents were asked to interact with their children as they normally would, and about half of children in the study played with puzzles at one time. Higher-income parents tended to have children play with puzzles more frequently, and both boys and girls who played with puzzles had better spatial skills. However, boys tended to play with more complex puzzles than girls, and the parents of boys provided more spatial language and were more active during puzzle play than parents of girls.The findings were published in the journal Developmental Science.24. In which aspect do children benefit from puzzle play?A. Building confidence.B. Developing spatial skills.C. Learning self-control.D. Gaining high-tech knowledge.25.What did Levine take into consideration when designing her experiment？A. Parents’ age.B. Children’s imagination.C. Parents’ education.D. Child-parent relationship.26. How do boy differ from girls in puzzle play?A. They play with puzzles more often.B. They tend to talk less during the game.C. They prefer to use more spatial language.D. They are likely to play with tougher puzzles.27. What is the text mainly about?A. A mathematical method.B. A scientific study.C. A woman psychologistD. A teaching program.2020山东卷阅读理解DAccording to a recent study in the Journal of Consumer Research, both the size and consumption habits of our eating companions can influence our food intake. And contrary to existing research that says you should avoid eating with heavier people who order large portions （份）, it’s the beanpoles with big appetites you really need to avoid.To test the effect of social influence on eating habits, the researchers conducted two experiments. In the first, 95 undergraduate women were individually invited into a lab to ostensibly（表面上）participate in a study about movie viewership. Before the film began, each woman was asked to help herself to a snack. An actor hired by the researchers grabbed her food first. In her natural state, the actor weighed 105 pounds. But in half the cases she wore a specially designed fat suit which increased her weight to 180 pounds.Both the fat and thin versions of the actor took a large amount of food. The participants followed suit, taking more food than they normally would have. However, they took significantly more when the actor was thin.For the second test, in one case the thin actor took two pieces of candy from the snack bowls. In the other case, she took 30 pieces. The results were similar to the first test: the participants followed suit but took significantly more candy when the thin actor took 30 pieces.The tests show that the social environment is extremely influential when we’re making decisions. If this fellow participant is going to eat more, so will I. Call it the “I’ll have what she’s having” effect. However, we’ll adjust the influence. If an overweight person is having a large portion, I’ll hold back a bit because I see the results of his eating habits. But if a thin person eats a lot, I’ll follow suit. If he can eat much and keep slim, why can’t I?12. What is the recent study mainly about?A. Food safety.B. Movie viewership.C. Consumer demand.D. Eating behavior.13. What does the underlined word "beanpoles" in paragraph 1 refer to?A. Big eaters.B. Overweight persons.C. Picky eaters.D. Tall thin persons.14. Why did the researchers hire the actor?A. To see how she would affect the participants.B. To test if the participants could recognize her.C. To find out what she would do in the two tests.D. To study why she could keep her weight down.15. On what basis do we "adjust the influence" according to the last paragraph?A. How hungry we are.B. How slim we want to be.C. How we perceive others.D. How we feel about the food.2020深圳第二次线上测试Pinocchio may be just a children’s fairy tale, but Spanish scientists at the University of Granada recently investigated this so-called “Pinocchio effect” and found that our noses don’t grow when we tell a lie, but actually shrink a bit.Dr. Gómez Milán and his team developed a lie detector test that used thermography（体温计）to tell if people were lying, and found that whenever participants in their research were being untruthful, the temperature of the tip of their nose dropped up to 1.2℃, while the temperature of their forehead increased up to 1.5℃. Scientist also found that drop in temperature at nose level actually caused it to slightly shrink, although the difference is undetected by the human eye.“One has to think in order to lie, which rises the temperature of the forehead,” Dr. Gómez Milán explained the findings. “At the same time we feel anxious, which lowers the temperature of the nose.”For this study, researchers asked a number of 60 students to perform various tasks while their temperature is scanned by technology. One of these tasks required making a 3 to 4 minutes call to their parents or a friend and telling a significant lie. Participants had to make up the lie themselves during the call. Interestingly, this lie detector picked up the “Pinocchio effect” temperature difference in 80 percent of the test subjects, which is a better rate of success than that of any modern lie detector.“With this method we have achieved to increase accuracy”, said Dr. Gómez Milán, who added that law enforcement interviewers could one day combine other lie detection technology with thermal imaging to achieve better results.1.Why does the writer talk about Pinocchio in the first paragraph?A.To tell a fairy tale.B.To give an example.C.To talk about a scientist.D.To introduce the topic.2.What is “Pinocchio effect”?A.Our noses will grow when we tell a lie.B.Our noses will shrink when we tell a lie.C.The temperature of the forehead falls if we lie.D.The temperature of the student rises for anxiety.3.How did Dr. Gómez Milán feel about the lie detector?A.Doubtful.B.Surprised.C.Confident.D.Puzzled.4.What lesson can we learn from the text?A.A lie will travel very hard.B.Many ways to bring a liar to light.C.A lie never lives to be old.D.Once a liar always a liar.2018北京高考阅读CPlastic-Eating WormsHumans produce more than 300 million tons of plastic every year. Almost half of that winds up in landfills(垃圾填埋场), and up to 12 million tons pollute the oceans. So far there is no effective way to get rid of it, but a new study suggests an answer may lie in the stomachs of some hungry worms.Researchers in Spain and England recently found that the worms of the greater wax moth can break down polyethylene, which accounts for 40% of plastics. The team left 100 wax worms on a commercial polyethylene shopping bag for 12 hours, and the worms consumed and broke down about 92 milligrams, or almost 3% of it. To confirm that the worms’ chewing alon e was not responsible for the polyethylene breakdown, the researchers made some worms into paste(糊状物) and applied it to plastic films. 14 hours later the films had lost 13% of their mass — apparently broken down by enzymes (酶) from the worms’ stomachs. The ir findings were published in Current Biology in 2017.Federica Bertocchini, co-author of the study, says the worms’ ability to break down their everyday food — beeswax — also allows them to break down plastic. “Wax is a complex mixture, but the basic bond in polyethylene, the carbon-carbon bond, is there as well, ”she explains, “The wax worm evolved a method or system to break this bond. ”Jennifer DeBruyn, a microbiologist at the University of Tennessee, who was not involved in the study, says it is not surprising that such worms can break down polyethylene. But compared with previous studies, she finds the speed of breaking down in this one exciting. The next step, DeBruyn says, will be to identify the cause of the breakdown. Is it an enzyme produced by the worm itself or by its gut microbes(肠道微生物)?Bertocchini agrees and hopes her team’s findings might one day help employ the enzyme to break down plastics in landfills. But she expects using the chemical in some kind of industrial process — not simply “millions of worms thrown on top of the plastic.”43. What can we learn about the worms in the study?A. They take plastics as their everyday food.B. They are newly evolved creatures.C. They can consume plastics.D. They wind up in landfills.44. According to Jennifer DeBruyn, the next step of the study is to .A. identify other means of the breakdownB. find out the source of the enzymeC. confirm the research findingsD. increase the breakdown speed45. It can be inferred from the last paragraph that the chemical might .A. help to raise wormsB. help make plastic bagsC. be used to clean the oceansD. be produced in factories in future46. What is the main purpose of the passage?A. To explain a study method on worms.B. To introduce the diet of a special worm.C. To present a way to break down plastics.D. To propose new means to keep eco-balance.2020高考英语全国II卷B keys:BCDB24.B 细节理解题。

高考英语说明文4篇1Here is an astonishing and significant fact: Mental work alone can’t makeus tire. It sounds absurd/əb'sɜːd/荒谬的. But a years ago, scientists tried to find out how long the human brain could labor without reaching a stage 阶段of fatigue /fə'tiːg/(疲劳). To the amazement of these scientists, they discovered that blood passing through the brain, when it is active, shows no fatigue at all! If we tooka drop of blood from a day laborer劳动者, we would find it fullof fatigue toxins /'tɒksɪn/ (毒素) and fatigue products. But if wetook blood from the brain of an Albert Einstein, it would show nofatigue toxins at the end of the day.So far as the brain is concerned, it can work as well and swiftly很快地at the end of eight or even twelve hours of effort as at the beginning. The brain istotally tireless. So what makes us tired?Some scientists declare that most of our fatigue comes from our mental and emotional(情绪的) attitudes. One of England’s most outstanding scientists, J.A. Hadfield, says, “The greater part of the fatigue from which we suffer is of mental origin /'ɒrɪdʒɪn/起源. In fact, fatigue of purely physical origin is rare.”Dr. Brill, a famous American scientist, goes even further. He declares, “One hundred percent of the fatigue of sitting worker in good health is due to emotional problems.”What kinds of emotions make sitting workers tired? Joy? Satisfaction?No! A feeling of being bored, anger, anxiety/æŋ'zaɪətɪ/焦虑, tenseness紧张, worry, a feeling of not being appreciated---those are the emotions that tire sitting workers. Hard work by itself seldom causes fatigue. We get tired because our emotions produce nervousness in the body.1. What surprised the scientists a few years ago?A. Fatigue toxins could hardly be found in a laborer’s blood.B. Albert Einstein didn’t feel worn after a day’s work.C. The brain could work for many hours without fatigue.D. A mental worker’s blood was filled with fatigue toxins.2. According to the author, which of the following can make sitting workers tired?A. Challenging mental work.B. Unpleasant emotions.C. Endless tasks.D. Physical labo3. What’s the author’s attitude towards the scientists’ idea?A. He agrees with them.B. He doubts them.C. He argues against them.D. He hesitates to accept them.4. We can infer from the passage that in order to stay energetic, sitting workers need to ________.A. have some good food.B. enjoy their workC. exercise regularlyD. discover fatigue toxins2They baby is just one day old and has not yet left hospital. She is quietbut alert /ə'lɜːt/（警觉）. Twenty centimeters厘from her face researchershave placed a white card with two black spots on it. She stares at it carefully.A researcher removes the card and replaces it by another, this time with the spots differently spaced. As the cards change from one to the other, her gaze（凝视）starts to lose its focus — until a third, with three black spots,is presented. Her gaze returns: she looks at it for twice as long as she did at the previous card. Can she tell that the number two is different from three, just 24 hours after coming into the world?Or do newborns simply prefer more to fewer? The same experiment, but with three spots shown before two, shows the same return of interest when the number of spots changes. Perhaps it is just the newness 名，新奇? When slightly older babies were shown cards with pictures of objects (a comb, a key, an orange and so on), changing the number of objects had an effect separate from changing the objects themselves. Could it be the pattern that two things make, as opposed to three? No again. Babies paid more attention to squares moving randomly on a screen when their number changed from two to three,or three to two. The effect even crosses between senses. Babies who were repeatedly shown two spots became more excited when they then heard three drumbeats than when they heard just two; likewise （同样地）when the researchers started with drumbeats and moved to spots.5. The experiment described in Paragraph 1 is related to the baby’s__.A. sense of hearingB. sense of sightC. sense of touch D sense of smell6. Babies are sensitive to the change in______.A. the size of cardsB. the colour of picturesC. the shape of patternsD. the number of objects7. Why did the researchers test the babies with drumbeats?A. To reduce the difficulty of the experiment.B. To see howbabies recognize sounds.C. To carry their experiment further.D. To keep the babies’interest.8. Where does this text probably come from?A. Science fiction.B. Children’s literature.C. An advertisement.D.A science report3Last night’s meteor(流星) 英/'miːtɪə/ shower left many people in the community dissatisfied and demanding 苛求的；要求高的；吃力的answers. According to Gabe Rothsclild, Emerald Valley’s mayor市长, people gathered in thesuburbs /'sʌbɜːb/of the city, carrying heavy telescopes, expecting to watch the brightly burning meteors passing through the sky. What they found instead was a sky so brightene by the city’s lights that it darkened the light of the meteors passing overhead. “My family was so frustrated,” admitted town resident Duane Cosby, “We wanted to make this an unforgettable family outing, but it turned out to be a huge disappointments.”Astronomers- /ə'strɒnəmə/n. 天文学家--scientists who study stars and planets---- have beencomplaining about this problem for decades. They say that light pollution prevents them from seeing objects in the sky that they could see quite easily in the past. They call on people and the government to take measures to fightagainst it.There is yet a population besides professional and amateur /ˈæmətə(r)/美 /'æmə.tʃʊr/n. 爱好者star observers that suffers even more from light pollution. This population consists of birds, bats frogs, snakes, etc. For example, outdoor lighting severely affects migrating(迁徙的)birds. According to the International Dark-Sky Association. “100million birds a year throughout North America die in crashes 撞碎with lighted buildings and towers.”Countless more animals casualties(伤亡）result from the use of artificial lighting. Clearly, people enjoy the benefits of lighting their evenings, but some scientists think it can be harmful for humans, too. They worry that exposure to light while sleeping can increase pers on’s chances of getting cancer. Emerald Valley is only one community that is becoming aware of the negative effects of light pollution. For years, Flagstaff, Arizona/,æri'zəunə/美 /,æri'zəunə/n. 美国亚利桑那州, has enforced lighting regulations in its city in order to assist astronomers at the Lowell Observatory.英 /əb'zɜːvət(ə)rɪ/美 /əb'zɝvətɔri/n. 天文台；气象台；瞭望台Similar efforts have been made worldwide, and a movement isunderway 进行中的to remind us to turn off lights when we are not using them, so thatother creatures can share the night.9.It happened last night thatA. the city’s lights affected the meteor watchingB. the meteors flew past before being noticedC. the city light show attracted many peopleD. the meteor watching ended up a social outing10.

We do know，however，that they existed over 5,500years ago in ancient Asia.The oldest known transport wheel was discovered in 2002 in Slovenia. It is over 5，100 years old. Evidence suggests thatwheels for transport didn't become popular for .while, though . This could be because animals did a perfectly good job of carryingfarming tools and humans around.But it could also be because of a difficult situation. While wheels need to roll on smooth surfaces, roads with smooth surfaces weren't going to be constructed until there was plenty of demand for them. Eventually, road surfaces did become smoother, but this difficult situation appeared again a few centuries later. There had been no important changes in wheel and vehicle design before the arrival of modern road design.In the mid-1700s,a Frenchman came up with a new design of road--a base layer (层)of large stones covered with a thin layer of smaller stones. A Scotsman苏格兰人improved on this design in the 1820s and a strong, lasting road surface became a reality. At around the same time, metal hubs英 /hʌb/美 /hʌb/n. 中心；毂；木片(the central part of a wheel)、came into being, followed by the Wheels were invented in 1967, sixty years after the appearance of tarmacked roads(泊油路).

1科教科普类1、Australia leads the world in its number of resident poisonous spiders as well as the strengthof their toxicity( 毒性 ). However,of almost 9,800 species most are perfectly harmless andinteresting.Spider diversity is broad and many fascinating species occur here that range from the large tothe tiny and hardly noticed, and from the dullest black to the strangely shaped.Spiders can be roughly classified according to the strategies( 策略) they use for feeding.Spiders which appeared earlier in the evolutionary scale feed by waiting in a cave for food to comealong before grabbing it. Following them were spiders which actively wandered looking forfood and which caught it by chasing it down. The evolution of flying insects makes spiders evolvenew ways of catching food which couldn’ t be chased and so the earliest air web weavers arose.Most spiders feed on insects and other arthropods but the Whistling Spider feeds on frogs andsmall birds. The Golden Orb Spider also feeds on small birds.A spider periodically sheds( 蜕皮 ;脱落 ) its skin so that it can grow. Immature stages are called moults. Each species has a particular number of moults that it will go through before reaching itsfinal adult stage.Usually, once male spiders have mated, they die shortly after. But, even in death, Redbackmales often serve a purpose. The already pregnant Redback females always kill their lover and,in most cases, also eat them. This provides them with a small reproductive advantage.Allowing spiders to take up places around houses can be beneficial in that they catchother annoying insects such as mosquitoes and flies.Rest assured that while you might see some large spiders, and perhaps even some poisonousones, a good rule is to look and admire but don't touch any spider you find. Even those withoutpoison could still have a nasty bite.1.Different families of spiders are identified themselves by ______.A.their physical characterB.their ways of getting foodC.the strength of their toxicityD.their effect on the environment1A.Spiders that chase down insects for food.B.Spiders that wait for the insects to come along.C.Spiders that can weave webs to catch flying insects.D.Spiders that actively go out to look for insects as food.3.If a spider stays on the wall of your house, you______. ’ d betterA.kill itB.feed itC.let it beD.chase it out4.What is the passage mainly talking about?A.A brief introduction of spiders.B.The evolution process of spiders.C.Living harmoniously with spiders.D.The living and feeing habits of spiders.2、Many people believe that you lose the ability to learn new languages as you get older.Language experts,however,will tell you that you’ re never too old to learn a new language. As youget older, it can be more difficult to learn a new language,though.Children and adults learn new languages in different ways. For children, language is their life.They study for thousands of hours every year. Because they need to learn language to became partof their communities.Adults,on the other hand,are already part of a language community. Learninga new language means becoming part of another language community,and adults rarely get thechance to practice as much as young children do.Moreover.children leaning a new language are expected to make mistakes. This gives themfreedom when learning to be daring and confident Adults,however,often feel pressured to beperfect when learning a new language.This can discourage many people and make it even harderto learn a new language.When young children learn a new language,they come to see various languages as a“ normal”part of society.This mindset( 思维模式 ) helps them embrace learning a new language withoutSo if you want to learn a new language,go f or it! It’ s never too late to learn a new language. If you're older,it may take more work,but it can be done.If you're a young child,though,now is thetime to step out and learn a new language!1.By“ Language is their life” ,the author means that children.A.can't live without languageB.lead a happy life every dayC.practice a new language a lotD.are taken good care of adults2.What may make it hard for the old people to learn a new language!A.They are afraid of being laughed at.B.They usually have too many interests.C.They think making mistakes is natural.D.They always make all kinds of mistakes.3.Which of the following shows the difference between children and adults in learning newlanguage?A.The behaviors they have.B.The learning attitudes.C.The future plans they have made.D.The materials they are using.4.According to the author,a new language.A.can never be learned by the old peopleB.can be grasped by the people easilyC.can be understood only by the old peopleD.can learned by both the old and the young3、 Kids and teens are often dismissive of praise from their parents. I am sure that parents outthere can relate to this, as we all have been told at one time or another by one or several of ourkids,“ Stop it, Mom’’. or even,“ You’ re just saying that because you are my parents and you have to say that. " I can assure you, though, that they are listening. They will probably not thank you forthis praise until they are in their twenties, but don't let that stop you from praising them duringtheir childhood and teen years. Just be careful how you praise them. A little praise may go a long way —especially if it is the right kind of praise.It appears that the way to go is to praise their efforts according to a study by Brummelman, of Utrecht University in the Netherlands and colleagues. These researchers concluded that kids should be praised primarily for their efforts, rather than for their personal characteristics, becauseif they are praised for effort, then a poor performance is more likely to be seen as a glitch( 小故障 ), rather than a valid reflection of who they are as individuals.Let ’ s think about this together. If you are a teenager or a child of any age and are constantlytold how brilliant you are, then when you do poorly on a test or a few tests, you may feel like you have suddenly lost your status as brilliant and may now feel ashamed that you are merely averageor even dumb. If you are a girl who is constantly being told how beautiful you are, then on a day when you don’t look or feel so good, you may decide that you are unattractive. This is the problem that develops when we are praising our kids for global personality characteristics that theycan't always live up to.1.According to the passage, which of the following statements is the right kind of praise?A.You are a great artist.B.You are very intelligent.C.Wow, you have a special gift for music.D.Your painting has indeed improved due to your efforts.2.Which of the following statements is TRUE according to the passage?A.All the children should be praised.B.There ’ s no need to praise kids and teens.C.Praise should be beyond children’ s expectations.D.Teens often pay no attention to their parents’ praise.3.The underlined word“ dumb” in theagraphlastparcan be replaced by _________.A.stupidB.uniqueC.curiousD.honestA.why to praise kids and teensB.how to praise kids and teensC.different ways to praise kids and teensD.the importance of praising kids4、 Scientists, psychologists and English academics at Liverpool University have found thatreading the works of the classical writers like Shakespeare and Wordsworth has a great effect onthe mind, catches the reader’ s attentionriggersandmoments of self-examination.Using a special machine, they monitored the brain activity of 30 volunteers as they read worksby William Shakespeare, William Wordsworth, T.S. Eliot and others.In the first part of the research, the brain activity of 30 volunteers was monitored as they readpassages from Shakespeare’ s plays, including King Lear, Othello, Coriolanus and Macbeth, andagain as they read the text rewritten in a simpler form or modern language.While reading the common texts, normal levels of electrical activity were shown in their brains.When they read the works of Shakespeare, however, the levels of activity jumped because ofhis use of words which were unfamiliar to them. The result of the test showed that the morechallenging passages cause a greater degree of electrical activity in the brain than thecommon ones.Scientists went on to study the brain activity as it responded to each word and recorded how itlit up as the readers came across unusual words, surprising phrases or difficult sentences in theclassical works. As a result, this lightening up process of the mind lasted longer than that whenvolunteers read common texts, encouraging further reading.The research also found that reading poetry especially increases activity in the righthemisphere(半球 ) of the brain, an area connected with“ autobiographical memory” , driving the readers to think carefully about their own experiences based on what they have read. Theacademics said this meant the classical works of literature are more useful than self-help books.Philip Davis, an English professor who has worked on the study in the university’ s mag resonance center, announced this week:“ Classical literature acts-boosterlikearockettothe brain,which provides extra power for the brain.

No, according to aCalifornia District Court judge, who recently ruled that a child must be schooled "by a personholding a valid state teaching credential ( 文凭 )for the grade being ta ught ”.What started as a Los Angeles County child welfare case involving one specific family hasgone into proceedings ( 诉讼 ) that have actually put on trial the very nature of what constitutes asound education.“ For decades we’ ve been happily ling,homeschooandthen this comes upgiven homeschooling parents the freedom to choose the kind of education they want for theirchild.This particular family in Los Angeles had enrolled their children in a private schoolindependent study program not in their home. In response to abuse charges against the family, thechildren were enrolled in public schools. The parents stated they had a constitutional right tohomeschool on religious grounds; that's when the court ruling was issued. However, Griffith saysif the ruling ends up affecting anyone, it will mainly be those who also enroll their children inoff- site homeschooling.“ This won't-reachingbefar for homeschooling parents."That's how organizations like the Homeschool Association of California (HSC) would like tokeep it, anyway, and they've hired a team of lawyers to limit the impact of the case. Griffith saysthe legal team for HSC is trying to establish that while this ruling may indeed be necessary for thisparticular family, it should not set a precedent( 先例 ) for all.What does this case really mean for homeschooling families nationwide? According to DarrenA. Jones, this decision is certain to affect homeschooling on a national scale. Jones claims that it iscommon for state courts to look to other states’ rulings for assistance in deciding issues where no precedent exists.“ A poor legal decision in California could become part of a trend acrosse thnation.’’1.In Griffith’ s opinion, ________.A.parents don’ t have a right to homeschool their childrenB.a child must be schooled by an expert with a credentialC.homeschooling should be forbidden in the whole countryD.it is understandable for parents to homeschool their children2.The underlined word“ this” in Para. 2 refers to the fact that.A.parents happily homeschool their childrenB.parents don’ t have a right to homeschool their childrenC.a child must be schooled by a person with a teaching credentialD.a Los Angeles County child welfare case involves a special family3.Why were the particular family’ s children enrolled in public schools?A.To avoid the abuse charges against them.C.To break away from their parents.D.To cooperate with the expert’ s jobs.4.What ’ s the author’ s attitude towards whether parents have a right to homeschool their children?A.Supportive.B.Sympatric.C.Negative.D.Objective.6、Summer shouldn't mean taking a break from learning, especially reading. Studies show thatmost students experience a loss of reading skills over the summer months, but children whocontinue to read actually gain skills. So efforts should be made during the summer to helpchildren keep reading skills, practice reading and read for enjoyment.Parents should remember that children need free time in the summer to relax and enjoy thepleasures of childhood. So summer reading should be fun. Following are a few tips to makereading enjoyable for your children this summer:Read aloud together with your child every day.Make it fun by reading outdoors on the front steps, patio, at the beach or park. Also, let yourchildren read to you.Set a good example!Keep lots of reading material around the house. Turn off the TV and have each person readhis or her book, including Mom and Dad.Read the same book your child is reading and discuss it.This is the way to develop habits of the mind and build capacity(能力) for thought and insight.Let kids choose what they want to read, and don turn your nose’upt at popular fiction. It willonly discourage the reading habit.Subscribe, in your child’ s name, to magazines.Encourage older children to read the newspaper and current events magazines, to keep up the reading habit over the summer and develop vocabulary. Ask them what they think about whatthey ’ ve read, and listen to what they say.1.Parents must help children read during the summer because ________.A.the summer holiday is too long a time for themB.reading is a kind of relaxation for childrenC.some of the reading skills may be lost if they stop readingD.children can enjoy the pleasure of childhood2.What does the underlined phrase "turn your nose up at” probably mean?A.Get interested in.B.Show one ’ s dislike for.C.Think highly of.D.Lose interest in.3.In oder to build children's capacity for thought and insight, parents should ______.A.subscribe to magazines in the child’ s nameB.read the same book the child is reading and discuss itC.let children choose what they want to readD.turn off the TV4.What does the passage mainly tell about?A.Some summer reading tips for parents.B.Some useful advice on reading for children.C.What kinds of books to read in summer.D.How to teach children to read.7、 Have you got the information taught by your teacher in class? Have you understood what you saw on the screen? Maybe everyone has their own learning style.Generally speaking, we gather information with our minds and bodies in different ways, such as seeing, hearing and doing. Then our brains deals with that information, organizing it and connecting it to things we are already aware of. In other words, our brains will deal with the information in different ways. Sometimes we think in pictures or words. Sometimes we remember details or the big pictures.For different people, their learning styles are different too. One person may find it hard to make out the information in written forms but easy to know it immediately in an oral description. However, another person might find difficulties with the picture but the written message.Now scientists say there exist seven basic learning styles.·Linguistic: These people learn through listening, reading, speaking and writing.·Logical: These people learn with formula (公式) and principles (原理).·Visual: These people learn by seeing what they are studying.·Musical: These people learn well when information is presented through music.·Kinesthetic: These people learn from movement and physical activities.·Intrapersonal: These people learn best by linking new information directly with their own experiences.·Interpersonal: These people learn well by working with others.Therefore, if you know what learning style is your strength, you can balance your weakness, and get a more successful learning experience.1.From the passage, we know that our brains ______.A.deal with the information in different waysB.send out the information in the same wayanize information with our bodiesD.gather information in the same way2.A visual learner usually learns _____.A.through listening and speakingB.by seeing what he is learningC.from movement and physical activitiesD.by linking new information with his experience3.A musical learner will find it easy to learn ______.A.with formulas and principlesB.by working with othersC.through reading and writingD.through music he hearsA.learn more successfullyB.gather more informationC.understand more quicklyD.exchange information better8、 In 2015 a paper published in a science magazine reported on the personality types of peopleliving in various London districts. Extroverts ( 外向的人 ), the researchers who wrote it haddiscovered, favored Richmond. Those who were most open to experience gathered in Hackney.People in Barnet scored lower than average on emotional stability.What this study did not address was whether someone’ s home range reflects their personality traits or imposes them. In other words, is what is going on“ nature培育”)? orHowever,“nurture” (in a piece of research just published, Dr. Holtmann of Otago University, in New Zealand, and hiscolleagues have filled that gap — at least, they have filled it for dunnocks.The dunnock is a European bird. It has, though, been introduced to New Zealand and itspopulation has boomed there. It is a well-studied species, and, in particular, some beingmeasurably bolder (更大胆的 ) and more tolerant of potential threats, such as nearby humanbeings, than others. The team’ s research area was the Botanic Garden in Dunedin. This is open tothe public, but some areas are more frequented by visitors than others. Dunnocks have smallterritories, so it was possible to measure the amount of human disturbance in a given territory withreasonable precision. And, by wrapping each of the dunnocks in the garden with colour-codedbands it was possible to identify individuals by sight. Altogether, the researchers looked at 99 ofthem.They worked out a bird’ s level of threat tolerance by the simple method of walking towards it,and then measuring how close one could get before the bird flew away. They did this several times foreach bird every breeding season, and repeated the process over the course of three seasons.A particular bird’ s flight distance (ie, how closely it could be approached before it departed)was, they found, consistent within a breeding season. From season to season most birds got a littlebolder— probably as they learnt more about the world and what they could safely get away with.But this increase in boldness with age was small compared with the different starting points of boldthat, on average, birds’ flight distances were inversely correlated负相关) (with the level of human disturbance in their territories. This was a consequence of disturbed territories being settledby bold birds, and undisturbed territories by shy ones.In the case of dunnocks, then, nature wins over nurture. Dr. Holtmann was able to show that personalities match circumstances, rather than being created by them. Dunnocks can recognizewhich places suit them best, and choose to settle in them shortly after they are fully fledged (羽翼丰满 ). Most likely, that is happening in London districts, too.1.What does the underlined words “ that gap ” in the second paragraph refer to?A.What the paper published in 2015 failed to handle.B.Why extroverts favour certain areas in London district.C.How Dr. Holtmann involved dunnocks in his study.D.What the former and latter study have in common.2.From Paragraph 3, we can know that dunnocks ________.A.are native to New ZealandB.have distinct personalitiesC.are bolder than human beingsD.can be easily identified by its color3.What conclusion did Dr. Holtmann draw from his study?A.It ’ s nurture rather than nature that matters in the case of dunnocks ’ behaviour.B.Birds ’ flight distances were in proportion to human disturbance in their territories.C.Dunnocks choose their habitats wisely in the first place rather than adapt to them.D.Bold birds and shy birds alike settle in undisturbed territories in the botanic garden.4.What is the author ’ s purpose in writingepassage?thA.To argue that circumstances cultivate certain personalities.B.To entertain readers with some funny facts about dunnocks.C.To present the finding of a scientific research about dunnocks.D.To confirm the assumption that personalities match circumstances.答案以及解析1答案及解析：答案： 1.B; 2.C; 3.C; 4.A解析： 1.细节理解题。

高考英语说明文4篇1Here is an astonishing and significant fact: Mental work alone can’t makeus tire. It sounds absurd/əb'sɜːd/荒谬的. But a years ago, scientists tried to find outhow long the human brain could labor without reaching a stage 阶段of fatigue /fə'tiːg/(疲劳). To the amazement of these scientists, they discovered that blood passing through the brain, when it is active, shows no fatigue at all! If we tooka drop of blood from a day laborer劳动者, we would find it full offatigue toxins /'tɒksɪn/ (毒素) and fatigue products. But if we tookblood from the brain of an Albert Einstein, it would show no fatiguetoxins at the end of the day.So far as the brain is concerned, it can work as well and swiftly很快地at the end of eight or even twelve hours of effort as at the beginning. The brain is totally tireless. So what makes us tired?Some scientists declare that most of our fatigue comes from our mentaland emotional(情绪的) attitudes. One of England’s most outstanding scientists, J.A. Hadfield, says, “The greater part of the fatigue from which wesuffer is of mental origin /'ɒrɪdʒɪn/起源. In fact, fatigue of purely physical origin is rare.”Dr. Brill, a famous American scientist, goes even further. He declares, “One hundred percent of the fatigue of sitting worker in good health is due to emotional problems.”What kinds of emotions make sitting workers tired? Joy? Satisfaction?No! A feeling of being bored, anger, anxiety/æŋ'zaɪətɪ/焦虑, tenseness紧张, worry, a feeling of not being appreciated---those are the emotions that tire sitting workers. Hard work by itself seldom causes fatigue. We get tired because our emotions produce nervousness in the body.1. What surprised the scientists a few years ago?A. Fatigue toxins could hardly be found in a laborer’s blood.B. Albert Einstein didn’t feel worn after a day’s work.C. The brain could work for many hours without fatigue.D. A mental worker’s blood was filled with fatigue toxins.2. According to the author, which of the following can make sitting workers tired?A. Challenging mental work.B. Unpleasant emotions.C. Endless tasks.D. Physical labo3. What’s the author’s attitude towards the scientists’ idea?A. He agrees with them.B. He doubts them.C. He argues against them.D. He hesitates to accept them.4. We can infer from the passage that in order to stay energetic, sitting workers need to ________.A. have some good food.B. enjoy their workC. exercise regularlyD. discover fatigue toxins2They baby is just one day old and has not yet left hospital. She is quietbut alert /ə'lɜːt/（警觉）. Twenty centimeters厘from her face researchers have placed a white card with two black spots on it. She stares at it carefully.A researcher removes the card and replaces it by another, this time with the spots differently spaced. As the cards change from one to the other, hergaze（凝视）starts to lose its focus — until a third, with three black spots,is presented. Her gaze returns: she looks at it for twice as long as she did atthe previous card. Can she tell that the number two is different from three,just 24 hours after coming into the world?Or do newborns simply prefer more to fewer? The same experiment, butwith three spots shown before two, shows the same return of interest whenthe number of spots changes. Perhaps it is just the newness 名，新奇? When slightly older babies were shown cards with pictures of objects (a comb, a key, an orange and so on), changing the number of objects had an effect separate from changing the objects themselves. Could it be the pattern that two things make, as opposed to three? No again. Babies paid more attention to squares moving randomly on a screen when their number changed from two to three,or three to two. The effect even crosses between senses. Babies who were repeatedly shown two spots became more excited when they then heard three drumbeats than when they heard just two; likewise （同样地）when the researchers started with drumbeats and moved to spots.5. The experiment described in Paragraph 1 is related to the baby’s__.A. sense of hearingB. sense of sightC. sense of touch D sense of smell6. Babies are sensitive to the change in______.A. the size of cardsB. the colour of picturesC. the shape of patternsD. the number of objects7. Why did the researchers test the babies with drumbeats?A. To reduce the difficulty of the experiment.B. To see howbabies recognize sounds.C. To carry their experiment further.D. To keep the babies’interest.8. Where does this text probably come from?A. Science fiction.B. Children’s literature.C. An advertisement.D.A science report3Last night’s meteor(流星) 英/'miːtɪə/ shower left many people in the community dissatisfied and demanding 苛求的；要求高的；吃力的answers. According to Gabe Rothsclild, Emerald Valley’s mayor市长, people gathered in the suburbs /'sʌbɜːb/ of the city, carrying heavy telescopes, expecting to watch the brightly burning meteors passing through the sky. What they found instead was a sky so brighteneby the city’s lights that it darkened the light of the meteors passing overhead.“My family was so frustrated,” admitted town resident Duane Cosby, “We wanted to make this an unforgettable family outing, but it turned out to be ahuge disappointments.”Astronomers- /ə'strɒnəmə/n. 天文学家--scientists who study stars and planets----have beencomplaining about this problem for decades. They say that light pollution prevents them from seeing objects in the sky that they could see quite easily in the past. They call on people and the government to take measures to fight against it.There is yet a population besides professional and amateur /ˈæmətə(r)/美 /'æmə.tʃʊr/n. 爱好者star observers that suffers even more from light pollution. This population consists of birds, bats frogs, snakes, etc. For example, outdoor lighting severely affects migrating(迁徙的)birds. According to the International Dark-Sky Association. “100million birds a year throughoutNorth America die in crashes 撞碎with lighted buildings and towers.”Countless more animals casualties(伤亡）result from the use of artificial lighting. Clearly, people enjoy the benefits of lighting their evenings, butsome scientists think it can be harmful for humans, too. They worry that exposure to light while sleeping can increase pers on’s chances of getting cancer. Emerald Valley is only one community that is becoming aware of the negative effects of light pollution. For years, Flagstaff, Arizona/,æri'zəunə/美 /,æri'zəunə/n. 美国亚利桑那州, has enforced lighting regulations in its city in order to assist astronomers at the Lowell Observatory.英 /əb'zɜːvət(ə)rɪ/美 /əb'zɝvətɔri/n. 天文台；气象台；瞭望台Similar efforts have been made worldwide, and a movement is underway 进行中的to remind us to turn off lights when we are not using them, so that other creatures can share the night.9.It happened last night thatA. the city’s lights affected the meteor watchingB. the meteors flew past before being noticedC. the city light show attracted many peopleD. the meteor watching ended up a social outing10. What do the astronomers complain about?A. Meteor showers occur less often than beforeB. Their observation equipment is in poor repairC. Light pollution has remained unsolved for yearsD.

Saving wildlife is saving ourselvesB. Great efforts should be made to save energyC. Human activities should be environmentally friendlyD. New equipment should be introduced for space study4Almost every machine with moving parts has wheels, yet no one knows exactly when the first wheel was invented or what it was used for. We do know，however，that they existed over 5,500years ago in ancient Asia.The oldest known transport wheel was discovered in 2002 in Slovenia. It is over 5，100 years old. Evidence suggests thatwheels for transport didn't become popular for .while, though . Thiscould be because animals did a perfectly good job of carryingfarming tools and humans around.But it could also be because of a difficult situation. While wheels need to roll on smooth surfaces, roads with smooth surfacesweren't going to be constructed until there was plenty of demandfor them. Eventually, road surfaces did become smoother, but this difficult situation appeared again a few centuries later. There hadbeen no important changes in wheel and vehicle design before thearrival of modern road design.In the mid-1700s,a Frenchman came up with a new design ofroad--a base layer (层)of large stones covered with a thin layer ofsmaller stones. A Scotsman苏格兰人improved on this design in the 1820s and a strong, lasting road surface became a reality. At around thesame time, metal hubs英 /hʌb/美 /hʌb/n. 中心；毂；木片(the central part of a wheel)、came into being, followed by the Wheels were invented in 1967, sixty years after the appearance of tarmacked roads(泊油路). As wheel design took off, vehicles got faster and faster.14. What might explain why transport wheels didn’t become popular for some time?A. Few knew how to use transport wheels.B. Humans carried farming tools just as well.C. Animals were a good means of transport.D. The existence of transport wheels was not known.15. What do we know about road design from the passage?A. It was easier than wheel design.B. It improved after big changes in vehicle design.C. It was promoted by fast-moving vehicles.D. It provided conditions for wheel design to develop.16.
