B．About 390.C．About 900. D．1,000.3．What can be inferred about obesity patients in Paragraph 5 ?A．They are not as hopeless as doctors think they are.B．Most of them have tried hard to lose weight，but in vain.C．Without their doctors’ constant coaching，there is little chance of their succeeding in losing weight.D．Most of them have just given up their hope of becoming less heavy.4．According to the passage，which factor contributes to the lack of dialogue between doctors and patients?A．Most doctors just never think of warning their patients about their weight problem.B. Many doctors find it difficult to persuade overweight people to lose weight.C．Most patients are too weakwilled to do anything about their weight.D．Many patients tend not to trust their doctors about their weight problem.5．Which of the following is the best title of the passage?A．Obesity in the USB．Trouble of overweight AmericansC．Talk more，help betterD．Doctors or patients—who to bear more blame?(2020·安庆市检测)When the time comes to send the kids to college，some Asian parents may do their budget in Malaysian money. Malaysia wants to become a regional center for higher education.“We’re introducing a bill in October to allow the University of London and other wellknown foreign universities to come in and establish fullscale branch campuses，” says Fong Chan Onn，the deputy minister with responsibility for Chinese education.The Universityof London will be opening a branch near Kuala Lumpur.Fong says Australian institutions have expressed interest.“Even one of the Japanese universities is interested，” he adds.Malaysia hopes the imports will solve several problems.Local universities have limited places and many are reserved for Malays and other native groups.Ethnic Chinese and Indians often have no choice but to study overseas—or not go to university at all.“The country has been spending billions on the thousands of students who go abroad for their higher education.” says Penang state assemblyman Kang Chin Seng.“The figure is almost equal to all the revenue we earn from tin mines.The government itself sends scholars (奖学金获得者)to other countries.Many could be placed in the foreign campuses here，saving government funds.”As an education center，Malaysia can even make money.“The slogan is that one foreign student studying in Malaysia is worth 4×365 tourist days，”says Fong.Kuala Lumpur is eyeing students from ASEAN countries，and perhaps Hong Kong，where it is difficult to be admitted into local universities.Will foreign students come knocking? Prime Minister Mahathir Mohamad says Malaysia will be offering “quality education at reduced cost”．As for the local institutions，Fong believes they will rise to the challenge.Malaysia will know it has become a regional center for education when its homegrown schools can rival foreign universities as centers of excellence.6．What must be done before foreign universities can open branch campuses in Malaysia?A．A law allowing them to do so must be passed.B．Education fees must be the same in all universities.C．There must be enough applications from foreign students.D．Malaysian scholars must finish their education overseas.7．The underlined word “revenue”in the second paragraph means________.A．taxes B．moneyC．costs D．budget8．Students from ASEAN countries are expected to study in Malaysia because________.A．they will be near their parentsB．education there will be good and affordableC．all of the subjects will be taught in ChineseD．the educational quality will be as good as the University of London 9．What is the best title for this passage?A．Malaysian International SchoolsB．Malaysian Education OpportunitiesC．Malaysia’s Plan for Educational ExcellenceD．Malaysian Education vs Chinese Education课时作业(十四)答案Ⅰ.完形填空[语篇解读] 每个人在一生中都会作出很多的决定，文章主要讲了在作出重要决定的时候，不能受别人的影响，要依赖自己，相信自己。
2020-2021高考英语压轴题专题复习——阅读理解的综合及详细答案
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。

Every corner is a wood and stone masterpiece, with high glass windows that look out to the huge cliffs of the valley.A man entered with his family and took a seat. He wasn't in uniform, but he walked with the dignity of a soldier, and a slight limp (跛行). My suspicion was confirmed when he removed his hat and placed it on the table where I could see it.

He was content to be left out of the conversation and allowed to take in the wonderful and impressive view of the waterfall.I watched him, and imagined how many horrors he had seen in the war. What losses did he suffer, and how many friends did he lose? What he had witnessed should have given him a good reason to lose faith in the world. Yet this tired soldier was smiling at the sky, at the sun and the roar of the waterfall. Somehow, after everything, the world was still beautiful to him.I walked over to him and said, “Excuse me, sir. I'm sorry to interrupt, but I saw your hat, and I just wanted to say thank you for serving.”He looked up at me, surprised, and said proudly, “You're welcome, and thank you, too.”I told him I would go home and tell my children about this experience that I'd met him.1．What can we know about the place where the author enjoyed lunch?A．It was only open to people of the upper class.B．It was once visited by many famous people.C．It was attractive because of its beautiful surroundings.D．It was modeled on scenes from American history.2．What can we learn from the passage?A．The author at first thought the gentleman was famous.B．The gentleman stood out because of his uniform.C．The gentleman's family didn't like to talk with him.D．The gentleman wasn't expecting the author to thank him.3．What encouraged the author to talk to the soldier?A．The soldier's disability.

I'd have preferred a really fast one that went upside down. But I was told I couldn't ride something like that, because my blood pressure could drop and I might have some danger.I wasn't nervous—I don't get frightened of anything. I was securely fastened, so I knew I wouldn't fall out. The roller coaster ride went on for three or four minutes, and the experience couldn't be better. And I raised a lot of money for the Derbyshire, Leicestershire & Rutland Air Ambulance fund, which was fantastic.People were saying I'd got a place in the Guinness World Records.

Jenifer Mauer has needed more willpower than the typical college student to pursue her goal of earning a nursing degree. That willpower bore fruit when Jennifer graduated from University of Wisconsin-Eau Claire and became the first in her large family to earn a bachelor's degree.Mauer, of Edgar, Wisconsin, grew up on a farm in a family of 10 children. Her dad worked at a job away from the farm, and her mother ran the farm with the kids. After high school, Jennifer attended a local technical college, working to pay her tuition(学费), because there was no extra money set aside for a college education. After graduation, she worked to help her sisters and brothers pay for their schooling.Jennifer now is married and has three children of her own. She decided to go back to college to advance her career and to be able to better support her family while doing something she loves: nursing. She chose the UW-Eau Claire program at Ministry Saint Joseph's Hospital in Marshfield because she was able to pursue her four-year degree close to home. She could drive to class and be home in the evening to help with her kids. Jenifer received great support from her family as she worked to earn her degree: Her husband worked two jobs to cover the bills, and her68-year-old mother helped take care of the children at times.Through it all, she remained in good academic standing and graduated with honors. Jennifer sacrificed(牺牲)to achieve her goal, giving up many nights with her kids and missing important events to study. ''Some nights my heart was breaking to have to pick between my kids and studying for exams or papers,'' she says. However, her children have learned an important lesson witnessing their mother earn her degree. Jennifer is a first-generation graduate and an inspiration to her family-and that's pretty powerful.4．What did Jennifer do after high school?A．She helped her dad with his work.B．She ran the family farm on her own.C．She supported herself through college.D．She taught her sisters and brothers at home.5．Why did Jennifer choose the program at Ministry Saint Joseph's Hospital in Marshfield?A．To take care of her kids easily.B．To learn from the best nurses.C．To save money for her parents.D．To find a well-paid job there.6．What did Jennifer sacrifice to achieve her goal?A．Her health.B．Her time with family.C．Her reputation.D．Her chance of promotion.7．What can we learn from Jenifer's story?A．Time is money.B．Love breaks down barriers.C．Hard work pays off.D．Education is the key to success.【答案】4．C5．A6．B7．C【解析】这是一篇记叙文。
2020-2021高考英语阅读理解(大题培优)及详细答案
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。

2020-2021高考英语(阅读理解提高练习题)压轴题训练含答案解析
一、高中英语阅读理解1．阅读理解During this shopping season, salesmen will come up with different strategies to get your business. Many product companies use specific colors to cause positive emotions and compete for a sale. However, sight is not the only sensory (感官的) retail that companies use. Sounds and smells can also influence consumers' purchasing decisions.Nobel Prize-winning research shows that our sense of smell has great power to cause an emotional response. A study published earlier this year compared purchasing in a French flower shop when the smell of lavender (薰衣草) was given off and when it wasn't. It found that the smell increased the number of consumers' purchasing items and the amount of their purchases. An earlier study using Nike shoes found that consumers desired the shoes more, and were willing to pay more, when the room had a mixed smell of flowers. Realizing the subconscious impact of smell, many stores apply artificial scents (气味) through their heating and air-conditioning vents (通风口) or place scent machines above their doors. For instance, a coconut scent might make that bikini more appealing as you long for a vacation.Ever felt frenzied due to a store's fast-paced music? Or calmed by a piece of light music? A retailer's choice of music can have a big impact on consumers' moods. One study found that when subjected to loud music, consumers will spend less time in a store. But interestingly, the researchers did not find a difference in sales or customers' satisfaction. Another interesting finding from a recent study was that customers actually shop longer when exposed to unfamiliar music. Just as department stores use different scents in certain departments, many use different music in some areas to appeal to varying consumers.Well, you could always leave the store and take a break, but the food court probably isn't your best choices as brands like Cinnabon and Panera Bread also use scents as part of their customers' experience. Online retailers (零售商) use a variety of other strategies to get your business, but you can always neglect those and enjoy the familiar scents of home.（1）The passage is mainly about ________.A. consumers' favorite sounds and smells while shoppingB. shopping malls' strategies for satisfying consumersC. some special services from super shopping mallsD. two factors affecting consumers' shopping decisions（2）What can be inferred from Paragraph 2?A. Decorating stores with flowers becomes a fashion.B. Shops with special smells can attract more consumers.C. Smells can actually help businessmen gain more profits.D. The products with a kind of special smell are more popular.（3）How does music have an effect on consumers?A. It controls consumers' desire for shopping.B. It influences how long consumers stay in a shop.C. It gives consumers the satisfaction of enjoying shopping.D. Whether consumers are willing to buy things depends on it.（4）Which of the following can replace the underlined word “frenzied” in Paragraph 3?A. Satisfied.B. Depressed.C. Surprised.D. Excited.（5）What does the writer try to express in the last paragraph?A. Online shopping is becoming more and more popular nowadays.B. People should spend more time at home with family members.C. People can choose to get rid of salesmen's promotion strategies.D. Smells and sounds are important for consumers' shopping experience.【答案】（1）D（2）C（3）B（4）D（5）C【解析】【分析】本文为说明文。

2020-2021高考英语综合题专练∶阅读理解及答案解析
一、高中英语阅读理解1．阅读理解Scientists at the University of Oxford have developed new artificial intelligence(AI) software to recognize and follow up the faces of chimpanzees(黑猩猩)in the wild. The new software will allow researchers and wildlife conservationists to significantly cut back on time spent analyzing videos, according to the new paper published in Science Advances.For species(物种)like chimpanzees which have complex social lives and live for many years, getting photos of their behavior taken from short-term field research can only tell us so much," says Dan Schofield, researcher and DPhil student at Oxford University's Private Models Lab, School of Anthropology. "By taking advantage of the power of machine learning to unlock large video files, it makes it possible to measure behavior over the long term."The computer model was trained using over 10 million images(影像):from Kyoto University s Primate Research Institute(PRI) video files of wild chimpanzees in Guinea, West Africa. The new software is the first to continuously track and recognize individual a wide range of poses, performing with high accuracy in difficult conditions such as low lighting and poor image quality. "Access to this large video file has allowed us to use deep neural networks to train models to a degree that was previously not possible," says Arsha Nagrad, co-auther of the study and DPhil student at the Department of Engineer Science, University of Oxford." Additionally, our new software differs from previous primate face recognition software in that it can be applied to videos with limited manual intervention(人工干预), saving hours of time."The technology can be potentially used to monitor species for conservation Although the present application focuses on chimpanzees, the AI software provided will be applied to other species, and help drive the adoption of AI systems to solve(解决)a range of problems in the wildlife sciences.（1）What is the purpose of developing the new soft?A.To save wildlife researchers' time spent in the labs.B.To keep track of wildlife conservationists' behaviors.C.To protect chimpanzees and help them to live longer.D.To recognize and track the faces of wild chimpanzees.（2）What does the underlined word "it" in paragraph 2 refer to?A.Getting photos.B.Analyzing videos.C.A powerful machineD.The new AI software.（3）What does paragraph 4 mainly talk about?A.The working principle of the new software.B.Some limitations of using the new software.C.The unique advantages of the new software.D.Controversial attitudes to the new software.（4）What can be known from the last paragraph?A.Technology advance is the final goal of scienceB.The new software won't just be applied to chimpanzees.C.AI systems are widely used in the wildlife sciences.D.The application of the new technology isn't easy.【答案】（1）D（2）D（3）C（4）B【解析】【分析】本文是一篇说明文，介绍了一种新的人工智能软件，这种软件可以识别和追踪黑猩猩的面孔,大大节省了研究者和野生动物保护者的时间，而且它还可以应用到其他的物种研究。
2020-2021高考英语 阅读理解训练经典题目(含答案)
2020-2021高考英语阅读理解训练经典题目(含答案)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 than 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 C02.【答案】（1）D（2）A（3）A（4）B【解析】【分析】本文是一篇说明文。
