2021高考英语复习之高考真题阅读词块精析（三十五）2020江苏卷（C篇）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 men's 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 men's 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, itmay be wise to skip eating first.词块梳理1：stomach英[ˈstʌmək] 美[ˈstʌmək]n. 腹部；胃v. 欣赏；吃得下变形现在分词：stomaching过去式：stomached复数：stomachs第三人称单数：stomachs双语例句1.At the sight of blood her stomach turned.她看到血就感到恶心.2.My gorge [ stomach ] rises at it.我一看见这东西就恶心.3.I wouldn't say your stomach was big —it's just slightly convex.我不会说你的肚子大——它只是有点凸出.2：beneficial英[ˌbenɪˈfɪʃl] 美[ˌbenɪˈfɪʃl]adj. 有益的，有帮助的双语例句1.However, is the relationship stability always beneficial to channel members?然而, 关系稳定性对渠道成员来说一定是有利的吗?2.Passive FTP is beneficial to the client, but detrimental to FTP server admin.被动FTP对FTP客户端的管理有利, 但对服务器端的管理不利.3.Beneficial Right: Personal Right ?

一、高中英语阅读理解1．阅读理解A typical child plays many roles, such as friend, neighbor, son or daughter. Simply reminding children of that fact can lead to better problem-solving and more flexible thinking, according to new research from Duke University.Better problem-solving was just one positive finding of the study, said lead author Sarah Gaither, an assistant professor of psychology and neuroscience at Duke. After thinking about their own various identities, children also showed more flexible thinking about race and other social groupings—a behavior that could be valuable in an increasingly diverse society.In a series of experiments, Gaither and her colleagues looked at 196 children, ages 6 and 7. In an experiment, one group of children was reminded that they had various identities, such as son, daughter, reader or helper. A second group of children was reminded of their multiple physical attributes, such as a mouth, arms and legs. All the children then needed to handle a few tasksChildren who were reminded of their various identities showed stronger problem-solving and creative thinking skills. When shown pictures of a bear staring at honey-filled beehive(蜂窝)high up in a tree, these children had more creative ideas for how the bear might get the honey, such as turning over a bowl so that it became a stool(凳子). In other words, they saw a new use for the bowl. Children who were reminded of their multiple roles also showed more flexible thinking about social groupings. When asked to categorize different photos of faces, they suggested many ways to Spso. They identified smiling faces such as unsmiling ones, and old and young faces. The other children, meanwhile, primarily grouped people's faces by race and gender(性别).The-study suggests ways to promote flexible thinking for the young, which could be especially valuable for teachers." Gaither said."We have this tendency in our society to only think about ourselves in connection with one important group at a time," Gaither said. "When kids think that they have various identities, they show greater abilities."（1）What are all the kids asked to do in the experiments?A.Play different kinds of roles.B.Remind others of their roles.C.Approach several tasks.D.Classify a group of tasks.（2）How does the author mainly clarify the conclusions of the study in paragraph 4?A.By giving examples.B.By using experts' words.C.By listing a few figures.D.By showing cause and effect.（3）What can we learn from Sarah Gaither's words?A.Improving 5 kids flexible thinking ability is important teaching.B.Kids tend to behave selflessly after thinking about their roles.C.Kids' creative thinking ability is easy to discover and develop.D.Teachers are supposed to make the most of the kids' flexibility.（4）What is the best title for the text?A.Kids' Social Abilities Are Consistent with. Their Education.B.Considering Their Various Roles Improves Kids' Abilities.C.Kids Have a Variety of Identities in Their Daily Life.D.Problem-solving Ability Is Necessary for Most Kids.【答案】（1）C（2）A（3）A（4）B【解析】【分析】本文是一篇说明文，介绍了让孩子知道自己有不同的角色可以提高孩子解决问题的能力和创造性思维能力。

一、高中英语阅读理解1．（2019•浙江）阅读理解California has lost half its big trees since the 1930s, according to a study to be published Tuesday and climate change seems to be a major factor（因素）.The number of trees larger than two feet across has declined by 50 percent on more than 46, 000 square miles of California forests, the new study finds. No area was spared or unaffected, from the foggy northern coast to the Sierra Nevada Mountains to the San Gabriels above Los Angeles. In the Sierra high country, the number of big trees has fallen by more than 55 percent; in parts of southern California the decline was nearly 75 percent.Many factors contributed to the decline, said Patrick Mclntyre, an ecologist who was the lead author of the study. Woodcutters targeted big trees. Housing development pushed into the woods. Aggressive wildfire control has left California forests crowded with small trees that compete with big trees for resources（资源）.But in comparing a study of California forests done in the 1920s and 1930s with another one between 2001 and 2010, Mclntyre and his colleagues documented a widespread death of big trees that was evident even in wildlands protected from woodcutting or development.The loss of big trees was greatest in areas where trees had suffered the greatest water shortage. The researchers figured out water stress with a computer model that calculated how much water trees were getting in comparison with how much they needed, taking into account such things as rainfall, air temperature, dampness of soil, and the timing of snowmelt（融雪）.Since the 1930s, Mclntyre said, the biggest factors driving up water stress in the state have been rising temperatures, which cause trees to lose more water to the air, and earlier snowmelt, which reduces the water supply available to trees during the dry season.（1）What is the second paragraph mainly about?A. The seriousness of big-tree loss in California.B. The increasing variety of California big trees.C. The distribution of big trees in California forests.D. The influence of farming on big trees in California.（2）Which of the following is well-intentioned but may be bad for big trees?A. Ecological studies of forests.B. Banning woodcutting.C. Limiting housing development.D. Fire control measures.（3）What is a major cause of the water shortage according to Mclntyre?A. Inadequate snowmelt.B. A longer dry season.C. A warmer climate.D. Dampness of the air.（4）What can be a suitable title for the text?A. California's Forests: Where Have All the Big Trees Gone?B. Cutting of Big Trees to Be Prohibited in California Soon.C. Why Are the Big Trees Important to California Forests?D. Patrick Mclntyre: Grow More Big Trees in California【答案】（1）A（2）D（3）C（4）A【解析】【分析】本文属于议论文，围绕加利福尼亚的大树从20世纪30年代以来大量减少为主题，探讨出现这一现象的原因。

2021届高考英语复习之高考真题阅读词块精析(二十八)

2021高考英语复习之高考真题阅读词块精析（二十八）2020海南卷（C篇）In May 1987 the Golden Gate Bridge had a 50th birthday party. The bridge was closed to motor traffic so people could enjoy a walk across it. Organizers expected perhaps 50,000 people to show up. Instead, as many as 800, 000 crowded the roads to the bridge. By the time 250,000 were on the bridge, engineers noticed something terrible：the roadway was flattening under what turned out to be the heaviest load it had ever been asked to carry. Worse, it was beginning to sway（晃动）. The authorities closed access to the bridge and tens of thousands of people made their way back to land. A disaster was avoided.The story is one of scores in To Forgive Design：Understanding Failure, a book that is at once a love letter to engineering and a paean（赞歌）to its breakdowns. Its author, Dr. Henry Petroski, has long been writing about disasters. In this book, he includes the loss of the space shuttles（航天飞机）Challenger and Columbia, and the sinking of the Titanic.Though he acknowledges that engineering works can fail because the person who thought them up or engineered them simply got things wrong, in this book Dr. Petroski widens his view to consider the larger context in which such failures occur. Sometimes devices fail because a good design is constructed with low quality materials incompetently applied. Or perhaps a design works so well it is adopted elsewhere again and again, with seemingly harmless improvements, until, suddenly, it does not work at all anymore.Readers will encounter not only stories they have heard before, but some new stories and a moving discussion of the responsibility of the engineer to the public and the ways young engineers can be helped to grasp them."Success is success but that is all that it is," Dr. Petroski writes. It is failure that brings improvement.词块梳理1：trafficn. 交通；贸易；运输；通信量vt. 用…作交换；在…通行vi. 交易，买卖时态: trafficked, trafficking, traffics名词: trafficker近义词：[n.] collection, aggregation, accumulation, assemblage, commerce, commercialism, mercantilism [v.] trade, merchandise解析：communication: 指邮电、无线电、铁路、公路等各种交通方式或媒介。

一、高中英语阅读理解1．阅读理解City trees grow faster and die younger than trees in rural forestry, a new study finds. Over their lifetimes, then, urban trees will likely absorb less CO2 from the air thah forest trees.As we all know, the earth would be freezing or burning hot without CO2. However, CO2is a greenhouse gas, meaning it traps energy from the sun as/heat. That makes temperatures near the ground rise. Human activities, especially the widespread burning-of fossil(化石)fuels, have been sending extra greenhouse gases into the air. This has led to a rise in average temperatures across the globe.Studies had shown forests readily absorb CO2, but there hadn't been much data on whether city trees grow, die and absorb CO2at the same rate as forest trees do. So some researchers decided to find out.To figure out how quickly trees were growing, researchers tracked their diameters (the width of their trunks) between 2005 and 2014. A tree's diameter increases as it grows, just as a person's waist size increases as they gain weight. About half the weight of a tree is carbon, research has shown. Most of the rest is water. Over the nine years' tracking, the researchers found city trees absorbed four times as much carbon from the air as forest trees. However, they were twice as likely to die. So over the lifetime of each type of tree, forest trees actually absorbed more CO2.City trees grew faster because they had less competition for light from their neighbors. In a forest, trees tend to grow close together, shading their neighbors. Street trees also benefit from higher levels of nitrogen (氮)in rainwater. Nitrogen helps plants grow. Waste gases from gas-burning cars also contain nitrogen, thus enriching city air with nitrogen. Later, rainwater may wash much of it to the ground. Some street trees may also have better access to water than trees in the country because the underground water pipes can leak.（1）What can he known about CO2 from paragraph 2?A. It is one of the side effects of greenhouses.B. It greatly accelerates the process of global warming.C. It results from the widespread burning of fossil fuels.D. It prevents the earth from becoming unsuitable to live on.（2）Why did researchers track the diameters of trees?A. To know about their growth rates.B. To find out how much they weigh.C. To check whether they were healthy.D. To assess the carbon amounts in them.（3）What advantage do city trees have over forest trees?A. They are more likely to access growth promoters.B. They can enjoy more water coming from the air.C. They can enjoy more shade from neighbors.D. They are better at competing for light.（4）What will probably be talked about if the passage is continued?A. How urban trees can live longer.B. Why city living makes trees die young.C. How trees respond to dry soil conditions.D. Why faster-growing trees absorb more CO2.【答案】（1）D（2）A（3）A（4）B【解析】【分析】本文是一篇说明文，一项新的研究发现：与长在森林中的树木相比，城市里的树木长得更快，但死得更早。

一、高中英语阅读理解1．阅读理解On average, Americans spend about 10 hours a day in front of a computer or other electronic devices and less than 30 minutes a day outdoors. That is a claim made by David Strayer, a professor of psychology at the University of Utah. In his 2017 TED Talk, Strayer explained that all this time spent with technology is making our brains tired.Using an electronic device to answer emails, listen to the news and look at Facebook puts a lot of pressure on the front of the brain, which, Strayer explains , is important for critical (有判断力的)thinking , problem-solving and decision-making.So, it is important to give the brain a rest. And being in naure, Strayer claims, helps get a tired brain away from too much technology. More than 15,000 campers from around the world attended an international camping festival in September. That is when friends and family take time off and escape to nature for several days. They take walks, climb, explore, swim, sleep, eat and play. Camping may be just what a tired brain needs.Take Carl for example .He lives in West Virginia and enjoys camping. He says that staying outdoors makes him feel at ease. It also prepares him for the work he must do. Kate Somers is another example who also lives in West Virginia. She says she enjoys camping with her husband and two children. She calls it a “regenerative” experience.At the University of Utah, David Strayer has studied both short-term and long-term exposure to nature. He found that spending short amounts of time in nature without technology does calm the brain and helps it to remember better. However, he found, it is the long-term contact with nature that does the most good. He and his research team found that spending three days in nature without any technology is enough time for the brain to fully relax and reset itself.（1）What is David Strayer's opinion?A. Americans dislike outdoor activities.B. Electronic equipment should be quitted.C. New technologies are a double-edged sword.D. Electronic equipment brings great convenience.（2）Why does Strayer insist we go outdoors?A. To try another lifestyle.B. To refresh our brain.C. To make better decisions.D. To play with our family and friends.（3）What does the underlined word “regenerative” mean?A. RebornB. MemorableC. RemarkableD. Tiring（4）Which is the proper title for the passage?A. Electronic Equipment Harms the Brain.B. Good Rest Develops Good Memory.C. Tips on Using New Technologies.D. Being in Nature Is Good for the Brain.【答案】（1）C（2）B（3）A（4）D【解析】【分析】本文属于科普文，主要阐述电子产品的过多使用让大脑得不到休息，因而鼓励人们多进行户外活动，让大脑休息。

一、高中英语阅读理解1．阅读理解It started during a yoga class. She felt a strange pull on her neck, a feeling completely foreign to her. Her friend suggested she rush to the emergency room. It turned out that she was having a heart attack.She didn't share similar symptoms with someone who was likely to have a heart attack. She exercised, watched her plate and did not smoke. But on reviewing her medical history, I found that her cholesterol (胆固醇) level was sky-high. She had been prescribed a cholesterol-lowering statin (他汀) medication, but she never picked up the prescription because of the scary things she had read about statins on the Internet. She was the victim of fake medical news.While misinformation has been the object of great attention in politics, medical misinformation might lead to an increase in deaths. As is true with fake news in general, medical lies tend to spread further than truths on the Internet—and they have very real bad consequences.False medical information can also lead to patients experiencing greater side effects through the "nocebo effect (反安慰剂效应) ". Sometimes patients benefit from an intervention (干预) simply because they believe they will—that's the placebo effect (安慰剂效应). The nocebo effect is the opposite. Patients can experience harmful effects because they anticipate them. This is very true of statins. In blinded trials, patients who get statins are no more likely to report feeling muscle aches than patients who get a placebo. Yet, in clinical practice, according to one study, almost a fifth of patients taking statins report side effects, leading many to discontinue the drugs. What else is on the fake news hit list? As always, vaccines (疫苗) . False concerns that the vaccine may cause side effects have greatly reduced coverage rates.Cancer is another big target for pushers of medical misinformation—many of whom refuse alternative therapies. "Though most people think cancer tumors are bad, they're actually the way your body attempts to contain the harmful cells," one fake news story reads. It warns that prescription medications lead to the uncontrolled cell mutations (变异) .Silicon Valley needs to face this problem. I am not a free-speech lawyer, but when human health is at risk, perhaps search engines, social media platforms and websites should be held responsible for promoting or hosting fake information. Meanwhile, journalists should do a better job of spreading accurate information.（1）We can learn from Paragraph 2 that ________.A. the woman paid little attention to her daily dietsB. the unhealthy lifestyle might lead to the woman's heart attackC. the symptom of the heart attack was familiar to the womanD. the woman didn't take the prescription due to fake medical news（2）According to the passage, the placebo effect functions because patients ________. A. neglect necessary treatment B. discontinue the harmful drugsC. believe the benefits of an interventionD. suffer more side effects（3）What does the author mean by claiming that "he is not a free-speech lawyer" in the lastparagraph?A. He is a lawyer very easy to speak to.B. He is good at speaking because of his job.C. He is available to give a speech on the law.D. He is very cautious when speaking something（4）The main purpose of the passage is to ________.A. remind us to take medication as prescribedB. warn us against fake medical news on the InternetC. encourage journalists to report more positive news eventsD. teach us how to distinguish fake medical news on the Internet【答案】（1）D（2）C（3）D（4）B【解析】【分析】本文是一篇议论文，通过举例来论证了网络谣言，尤其是关于药物的网络谣言有巨大的杀伤力。

（1）考查细节理解。

根据第二段中的”...,but she never picked up the prescription because of the scary things she had read about stains on the Internet."她从来没有拿过这个处方，因为她在网上看到关于他汀的可怕事情，可知，由于虚假的医疗信息，这名女子没有服用那个处方药。

故选D。

（2）考查细节理解。

根据第四段中的“Sometimes patients benefit from an intervention simply because they believe they will—that's the placebo effect.”有时患者从干预中获益仅仅是因为他们相信他们会——这就是安慰剂效应，可知，安慰剂效应的作用是因为患者相信干预的好处。

故选C。

（3）考查词义猜测。

根据最后一段中的“I am not a free-speech lawyer, but when human health is at risk,perhaps search engines, social media platforms and websites should be held responsible for promoting or hosting fake information.”我不是一个言论自由的律师，但当人类健康受到威胁时，或许搜索引擎、社交媒体平台和网站应该为推广或提供虚假信息负责，可知，他不赞成随口造谣、传谣的，同时他说话很谨慎。
