十年（20102020）高考英语真题分项详解18阅读理解说明文体类1.（2020年，江苏卷）For those who can stomach it, working out before breakfast may be more beneficial for health than eating first, according to a study of meal timing and physical activity.Athletes and scientists have long known that meal timing affects performance. However, far less has been known about how meal timing and exercise might affect general health.To find out, British scientists conducted a study. They first found 10 overweight and inactive but otherwise healthy young men, whose lifestyles are, for better and worse, representative of those of most of us. They tested the mens fitness and resting metabolic (新陈代谢的) rates and took samples (样品) of their blood and fat tissue.Then, on two separate morning visits to the scientists lab, each man walked for an hour at an average speed that, in theory, should allow his body to rely mainly on fat for fuel. Before one of these workouts, the men skipped breakfast, meaning that they exercised on a completely empty stomach after a long overnight fast (禁食). On the other occasion, they ate a rich morning meal about two hours before they started walking.Just before and an hour after each workout, the scientists took additional samples of the mens blood and fat tissue.Then they compared the samples. There were considerable differences. Most obviously, the men displayed lower blood sugar levels at the start of their workouts when they had skipped breakfast than when they had eaten. As a result, they burned more fat during walks on an empty stomach than when they had eaten first. On the other hand, they burned slightly more calories (卡路里), on average, during the workout after breakfast than after fasting.But it was the effects deep within the fat cells that may have been the most significant, the researchers found. Multiple genes behaved differently, depending on whether someone had eaten or not before walking. Many of these genes produce proteins (蛋白质) that can improve blood sugar regulation and insulin (胰岛素) levels throughout the body and so are associated with improved metabolic health. These genes were much more active when the men had fasted before exercise than when they had breakfasted.The implication of these results is that to gain the greatest health benefits from exercise, it may be wise to skip eating first.1.The underlined expression “stomach it” in Paragraph 1 most probably means “_”.A.digest the meal easilyB.manage without breakfastC.decide wisely what to eatD.eat whatever is offered2.Why were the 10 people chosen for the experiment?A.Their lifestyles were typical of ordinary people.B.Their lack of exercise led to overweight.C.They could walk at an average speed.D.They had slow metabolic rates.3.What happened to those who ate breakfast before exercise?A.They successfully lost weight.B.They consumed a bit more calories.C.They burned more fat on average.D.They displayed higher insulin levels.4.What could be learned from the research?A.A workout after breakfast improves gene performances.B.Too much workout often slows metabolic rates.C.Lifestyle is not as important as morning exercise.D.Physical exercise before breakfast is better for health.【答案】1.B 2.A 3.B 4.D【解析】本文是说明文。文章介绍了一项研究，结果表明对于那些能忍受的人来说，不吃早餐锻炼可能对健康更有益。1.词句猜测题。根据下文working out before breakfast may be more beneficial for health than eating first可知，早餐前锻炼可能比先吃饭再锻炼对健康更有益，因此推断这里说的是那些不吃早饭先锻炼的人，因此推断划线词与B项“不吃早饭能应付”意思相近。故选B。2.细节理解题。根据第三段的They first found 10 overweight and inactive but otherwise healthy young men, whose lifestyles are far better and worse, representative of those of most of us.可知，他们首先找到了10个超重的，不活跃但健康的年轻人，他们的生活方式可以说更好，也可以说更糟，代表了我们大多数人。因此可知，实验时选择的10个人的生活方式代表了普通人。故选A。3.细节理解题。根据第六段的As a result, they burned more fat during walks on an empty stomach than when they had eaten first. On the other hand. they burned slightly more calories(卡路里), on average, during the workout after breakfast than after fasting.可知，结果，他们空腹散步时燃烧的脂肪比他们首先吃东西时所燃烧的脂肪要多。 另一方面。平均而言，他们在早餐后锻炼时燃烧的卡路里略多于禁食后。因此可知，锻炼前吃早饭消耗更多一点的热量。故选B。4.推理判断题。根据最后一段The implication of these results is that to gain the greatest health benefits from exercise, it may be wise to skip eating first.可知，这些结果的暗示，为了从运动中获得最大的健康益处，先不吃东西可能更明智。因此推断早饭前的体育锻炼对健康更有益。故选D。2.（2020年，江苏卷）Sometimes its hard to let go. For many British people, that can apply to institutions and objects that represent their countrys past-age-old castles, splendid homes and red phone boxes.Beaten first by the march of technology and lately by the terrible weather in junkyards (废品场), the phone boxes representative of an age are now making something of a comeback. Adapted in imaginative ways, many have reappeared on city streets and village greens housing tiny cafes, cellphone repair shops or even defibrillator machines (除颤器).The original iron boxes with the round roofs first appeared in 1926. They were designed by Giles Gilbert Scott, the architect of the Battersea Power Station in London. After becoming an important part of many British streets, the phone boxes began disappearing in the 1980s, with the rise of the mobile phone sending most of them away to the junkyards.About that time, Tony Inglis engineering and transport company got the job to remove phone boxes from the streets and sell them out. But Inglis ended up buying hundreds of them himself, with the idea of repairing and selling them. He said that he had heard the calls to preserve the boxes and had seen how some of them were listed as historic buildings.As Inglis and, later other businessmen, got to work, repurposed phone boxes began reappearing in cities and villages as people found new uses for them. Today, they are once again a familiar sight, playing roles that are often just as important for the community as their original purpose.In rural areas, where ambulances can take a relatively long time to arrive, the phone boxes have taken on a lifesaving role. Local organizations can adopt them for l pound, and install defibrillators to help in emergencies.Others also looked at the phone boxes and saw business opportunities. LoveFone, a company that advocates repairing cellphones rather than abandoning them, opened a mini workshop in a London phone box in 2016.The tiny shops made economic sense, according to Robert Kerr, a founder of LoveFone. He said that one of the boxes generated around $13,500 in revenue a month and cost only about $400 to rent.Inglis said phone boxes called to mind an age when things were built to last. “I like what they are to people, and I enjoy bringing things back,” he said.5.The phone boxes are making a comeback _.A.to form a beautiful sight of the cityB.to improve telecommunications servicesC.to remind people of a historical periodD.to meet the requirement of green economy6.Why did the phone boxes begin to go out of service in the 1980s?A.They were not well-designed.B.They provided bad services.C.They had too short a history.D.They lost to new technologies.7.The phone boxes are becoming popular mainly because of _.A.their new appearance and lower pricesB.the push of the local organizationsC.their changed roles and functionsD.the big funding of the businessmen【答案】5.C 6.D 7.C【解析】这是一篇说明文。文章讲述了在英国，电话亭在20世纪80年代开始停止使用。后来，一些商人使电话亭的角色和功能发生了变化，电话亭又变得流行起来。5.细节理解题。根据第一段Sometimes its hard to let go. For many British people, that can apply to institutions and objects that represent their countrys past-age-old castles, splendid homes. and red phone boxes.(有时候真的很难放手。对许多英国人来说，这可以适用于代表他们国家过去历史的机构和物品-古老的城堡、辉煌的住宅还有红色的电话亭)和最后一段Inglis said phone boxes called to mind an age when things were built to last.(英格利斯说，电话亭让人想起了一个东西经久耐用的时代)可知，电话亭正在卷土重来，以提醒人们一个历史时期。故选C。6.细节理解题。根据第三段After becoming an important part of many British streets, the phone boxes began disappearing in the 1980s, with the rise of the mobile phone sending most of them away to the junkyards.(在成为英国许多街道的重要组成部分后，电话亭在20世纪80年代开始消失，随着移动电话的兴起，大部分电话亭被扔到了垃圾场)可知，电话亭在20世纪80年代开始停止使用是因为它们输给了新技术。故选D。7.推理判断题。根据第五段As Inglis and, later other businessmen, got to work, repurposed phone boxes began reappearing in cities and villages as people found new uses for them. Today, they are once again a familiar sight, playing roles that are often just as important for the community as their original purpose.(随着英格利斯和后来的其他商人开始工作，改装后的电话亭开始在城市和乡村重新出现，人们发现了它们的新用途。今天，它们再次成为人们熟悉的景象，扮演着与它们最初的目的同样重要的角色)和第六段In rural areas, where ambulances can take a relatively long time to arrive, the phone boxes have taken on a lifesaving role.(在农村地区，救护车要花相当长的时间才能到达，电话亭就起到了拯救生命的作用)以及第七段Others also looked at the phone boxes and saw business opportunities.(其他人也在电话亭寻找商机)可推断出，电话亭之所以变得流行，主要是因为它们的角色和功能发生了变化。故选C。3.（2020年7月，浙江卷）Challenging work that requires lots of analytical thinking, planning and other managerial skills might help your brain stay sharp as you age, a study published Wednesday in the journal Neurology suggests.Researchers from the University of Leipzig in Germany gathered more than 1, 000 retired workers who were over age 75 and assessed the volunteers memory and thinking skills through a battery of tests. Then, for eight years, the scientists asked the same group to come back to the lab every 18 months to take the same sorts of tests.Those who had held mentally stimulating(刺激), demanding jobs before retirement tended to do the best on the tests. And they tended to lose cognitive(认知) function at a much slower rate than those with the least mentally challenging jobs. The results held true even after the scientists accounted for the participants overall health status.“This works just like physical exercise, ” says Francisca Then, who led the study. “After a long run, you may feel like youre in pain, you may feel tired. But it makes you fit. After a long day at work-sure, you will feel tired, but it can help your brain stay healthy. ”Its not just corporate jobs, or even paid work that can help keep your brain fit, Then points out. A waiters job, for example, that requires multitasking, teamwork and decision-making could be just as stimulating as any high-level office work. And “running a family household requires high-level planning and coordinating(协调), ” she says. “You have to organize the activities of the children and take care of the bills and groceries. ”Of course, our brains can decline as we grow older for lots of reasons-including other environmental influences or genetic factors. Still, continuing to challenge yourself mentally and keeping your mind busy can only help.8.Why did the scientists ask the volunteers to take the tests?A.To assess their health status.B.To evaluate their work habits.C.To analyze their personality.D.To measure their mental ability.9.How does Francisca Then explain her findings in paragraph 4?A.By using an experts words.B.By making a comparison.C.By referring to another study.D.By introducing a concept.10.Which of the following is the best title for the text?A.Retired Workers Can Pick Up New SkillsB.Old People Should Take Challenging JobsC.Your Tough Job Might Help Keep You SharpD.Cognitive Function May Decline As You Age【答案】8.D 9.B 10.C【解析】这是一篇说明文。神经病学杂志发布的一则研究显示，需要大量的分析思考、细致规划和其他管理技能有挑战性的工作，有可能会帮助你的大脑随着年龄的增长而保持敏锐。8.细节理解题。根据第二段第一句“Researchers from the University of Leipzig in Germany gathered more than 1,000 retired workers who were over age 75 and assessed the volunteers memory and thinking skills through a battery of tests.(来自德国莱比锡大学的研究人员召集了1000多名75岁以上的退休老人，并通过一系列的测试对他们的记忆力和思维能力进行了评估。)”可知，科学家让志愿者做测试是为了测试他们的心智能力。故选D项。9.推理判断题。根据第四段中Francisca Then说的话“This works just like physical exercise,( 这就像体育锻炼一样有效。)”及接下来进一步的解释“长跑后人就会感到痛苦和疲惫，但它确实能强身健体。工作一天下来会感到劳累，但这也使你的大脑处于健康状态”可知，Francisca Then是通过与“身体锻炼”作比较来解释他的发现的。故选B项。10.主旨大意题。第一段“Challenging work that requires lots of analytical thinking, planning and other managerial skills might help your brain stay sharp as you age(需要大量的分析思考、细致规划和其他管理技能有挑战性的工作，有可能会帮助你的大脑随着年龄的增长而保持敏锐。)”是本文的主题句，结合全文内容可知，文章主要讲述了有挑战性的工作可能会使大脑保持敏捷，所以C项“困难的工作可能有助于大脑保持敏捷”适合作本文标题。故选C项。4.（2020年7月，浙江卷）The traffic signals along Factoria Boulevard in Bellevue, Washington, generally dont flash the same length of green twice in a row, especially at rush hour. At 9:30am, the full red/yellow/green signal cycle might be 140 seconds. By 9:33am, a burst of additional traffic might push it to 145 seconds. Less traffic at 9:37am could push it down to 135. Just like the traffic itself, the timing of the signals changes.That is by design. Bellevue, a fast-growing city just east of Seattle, uses a system that is gaining popularity around the US: intersection(十字路口) signals that can adjust in real time to traffic conditions. These lights, known as adaptive signals, have led to significant declines in both the trouble and cost of travels between work and home.“Adaptive signals can make sure that the traffic demand that is there is being addressed, ” says Alex Stevanovic, a researcher at Florida Atlantic University.For all of Bellevues success, adaptive signals are not a cure-all for jammed roadways. Kevin Balke, a research engineer at the Texas A&M University Transportation Institute, says that while smart lights can be particularly beneficial for some cities, others are so jammed that only a sharp reduction in the number of cars on the road will make a meaningful difference. “Its not going to fix everything, but adaptive signals have some benefits for smaller cities,” he says.In Bellevue, the switch to adaptive signals has been a lesson in the value of welcoming new approaches. In the past, there was often an automatic reaction to increased traffic: just widen the roads, says Mark Poch, the Bellevue Transportation Departments traffic engineering manager. Now he hopes that other cities will consider making their streets run smarter instead of just making them bigger.11.What does the underlined word “that” in paragraph 2 refer to?A.Increased length of green lights.B.Shortened traffic signal cycle.C.Flexible timing of traffic signals.D.Smooth traffic flow on the road.12.What does Kevin Balke say about adaptive signals?A.They work better on broad roads.B.They should be used in other cities.C.They have greatly reduced traffic on the road.D.They are less helpful in cities seriously jammed.13.What can we learn from Bellevues success?A.It is rewarding to try new things.B.The old methods still work today.C.I pays to put theory into practice.D.The simplest way is the best way.【答案】11.C 12.D 13.A【解析】这是一篇说明文。美国华盛顿州的Bellevue采用了能随交通状况而调节交通灯时间的适应性信号灯，大大缓解了交通压力，也表明人们对于交通阻塞问题不再只是拓宽道路，而是能够采用新方法。11.指代猜测题。That位于第二段句首，应是指代第一段的内容。根据第一段内容尤其是第一段最后一句“Just like the traffic itself, the timing of the signals changes.(就像交通本身一样，信号灯的时间也会变化)”可知，第一段主要讲述的是信号灯的时间会灵活变化；“That is by design.”意为“那是有意为之”，由此可推知，That指代第一段中“信号灯的灵活时间”。故选C项。12.推理判断题。根据第四段第一句中“adaptive signals are not a cure-all for jammed roadways(但自适应信号并不是解决拥堵道路的万能药)”及第二句中“others are so jammed that only a sharp reduction in the number of cars on the road will make a meaningful difference(其他城市交通堵塞如此严重，只有减少道路上的车辆才能起有意义的作用) ”可推知，Kevin Balke认为适应性信号灯对于交通堵塞很严重的城市没有太大帮助。故选D项。13.推理判断题。根据第二段最后一句“These lights, known as adaptive signals, have led to significant declines in both the trouble and cost of travels between work and home.(这些灯，被称为适应性信号灯，已经大大减少了通勤的麻烦和花费)”最后一段第一句“In Bellevue, the switch to adaptive signals has been a lesson in the value of welcoming new approaches.(在Bellevue，对适应性信号灯的转变是一个在欢迎新方法的价值方面的榜样)”可推知，从Bellevue的成功中可以得出，尝试新事物是值得的。故选A项。5.（2020年7月，浙江卷）I am an active playgoer and play-reader, and perhaps my best reason for editing this book is a hope of sharing my enthusiasm for the theater with others. To do this I have searched through dozens of plays to find the ones that I think best show the power and purpose of the short play.Each play has a theme or central idea which the playwright(剧作家) hopes to get across through dialogue and action. A few characters are used to create a single impression growing out of the theme. It is not my intention to point out the central theme of each of the plays in this collection, for that would, indeed, ruin the pleasure of reading, discussing, and thinking about the plays and the effectiveness of the playwright. However, a variety of types is represented here. These include comedy, satire, poignant drama, historical and regional drama. To show the versatility(多面性) of the short play, I have included a guidance play, a radio play and a television play.Among the writers of the plays in this collection, Paul Green, Susan Glaspell, Maxwell Anderson, Thornton Wilder, William Saroyan, and Tennessee Williams have all received Pulitzer Prizes for their contributions to the theater. More information about the playwrights will be found at the end of this book.To get the most out of reading these plays, try to picture the play on stage, with you, the reader, in the audience. The houselights dim(变暗). The curtains are about to open, and in a few minutes the action and dialogue will tell you the story.14.What do we know about the author from the first paragraph?A.He has written dozens of plays.B.He has a deep love for the theater.C.He is a professional stage actor.D.He likes reading short plays to others.15.What does the author avoid doing in his work?A.Stating the plays central ideas.B.Selecting works by famous playwrights.C.Including various types of plays.D.Offering information on the playwrights.16.What does the author suggest readers do while reading the plays?A.Control their feelings.B.Apply their acting skills.C.Use their imagination.D.Keep their audience in mind.17.What is this text?A.A short story.B.An introduction to a book.C.A play review.D.An advertisement for a theater.【答案】14.B 15.A 16.C 17.B【解析】这是一篇说明文。文章主要介绍了作者的书籍的序言部分，包括其编写目的，书籍内容主体，以及如何实现有乐趣的阅读本书的建议。14.细节理解题。根据文章第一段内容“and perhaps my best reason for editing this book is a hope of sharing my enthusiasm for the theater with others”可知，作者编辑这本书的最好的原因是希望与他人分享对戏剧的热情，因此可知作者对于戏剧饱含热情。故选B项。15.细节理解题。根据文章第二段内容“It is not my intention to point out the central theme of each of the plays in this collection, for that would, indeed, ruin the pleasure of reading, discussing, and thinking about the plays and the effectiveness of the playwright.”可知，作者并不想指出这本书中每一部戏剧的中心主题，因为那样确实会破坏阅读、讨论和思考戏剧以及剧作家的有效性的乐趣。A项“Stating the plays”central ideas(陈述戏剧的中心思想)”与原文表达信息一致。故选A项。16.细节理解题。根据文章末尾段内容“To get the most out of the reading these plays, try to picture the play on stage, with you, the reader, in the audience.”可知，作者建议读者试着想象戏剧在舞台上上演，不再是读者而是成为观众，才能实现最佳的阅读乐趣。C项“Use their imagination”与原文“try to picture the play on the stage”表达信息一致。故选C项。17.推理判断题。根据文章首段内容“I am an active playgoer and play-reader, and perhaps my best reason for editing this book is a hope of sharing my enthusiasm for the theater with others”可知，该句内容应是书籍的“自序”内容，且结合末尾“To get the most out of the reading these plays, try to picture the play on stage, with you, the reader, in the audience.”可知，在讲述如何更好地实现阅读乐趣，再结合全文内容可推知，作者通过该文章介绍自己的一本书。故选B项。6.（2020年，天津卷，第一次高考）Transport has a lot to answer for when it comes to harming the planet. While cars and trains are moving towards greener, electric power, emissions from air travel are expected to increase massively by 2050. If we want big green sky solutions, we need blue sky thinking Fortunately, theres plenty of that happening right now, particularly the short-haul flights powered by batteries.Harbour Air is the largest seaplane airline in North America, flying 30, 000 commercial flights in 40 seaplanes each year. Significantly, all Harbour Air routes last less than 30 minutes, making it perfectly fit for electric engines. “As an airline, were currently in the process of turning all our planes into electric airplanes. says CEO Greg Mc Dougall. To make this happen, the airline has partnered up with MagniX to create the worlds first commercial flight with an electric eng
