山东省济南市济钢高级中学2019届高三第一次模拟(3月)考试语文试题

济钢高级中学高三语文试题2019.3一．现代文阅读（36分）（一）论述类文本阅读（本题共3小题，9分）阅读下面的文字,完1-3小题。

“文化全球化”是一个伪命题随着市场化、信息化在世界范围持续发展,跨时空的全球性交流互动不断由经济、科技领域走向政治、文化领域。

在这个过程中,全球文化一体化、世界文化趋同化、全球文化同质化等论调甚嚣尘上。

这种观点认为,经济全球化决定政治、文化全球化,世界市场使得消费主义走向全球各个角落,而通信、交通和网络的超地域性加速了不同民族和国家的文化融合,让不同民族和国家的文化最终走向趋同。

事实上,文化既有时代性又有民族性和地域性,其发展离不开自身所处时代和固有文化传统,所谓“文化全球化”是一个具有欺骗性的伪命题。

经济全球化是在不同民族和国家融入世界市场过程中发展起来的。

不同民族和国家经济发展、国家治理、民众生活的实际情况千差万别,在经济全球化进程中的地位和作用不尽相同,因而其参与经济全球化的利益诉求也各不相同。

在经济全球化进程中,为维护自身利益,不同民族和国家根据自身实际情况进行决策,并相应实行不同的国家治理模式。

在这种不同民族和国家基于维护与发展自身利益而形成的世界格局中,连经济都很难趋同,就更谈不上所谓的文化趋同。

文化是一个民族、一个国家的灵魂。

民族文化是长期发展和积累起来的,是一个民族的根脉。

由于人口种族、地理环境和社会生产方式等存在差异,不同民族和国家在历史发展中形成了不同的思维方式、价值取向、风俗习惯,造就了多元文化,而且每一种文化都具有无可替代性和不可复制性。

承认文化差异、实现文化共存,是各个民族和国家实现生存发展、开展国际合作的基础。

否认这种差异,盲目推动趋同,不但会导致人们自我身份认同的弱化甚至消失,而且将导致民族文化衰落和国家衰亡。

西方人鼓吹“文化全球化”,实质是向全世界兜售以美国为代表的西方文化。

一个人如果认同西方文化,就会更加乐于消费其商品、接受其制度规则。

What do the four events have in common?A. Family-based.B. Science-themed.C. Picked by children.D. Filled with adventuresAs a first responder, you never know what type of situation you might walk into, or who you’ll meet along the way. That’s definitely been the case for Jeffrey Lanenberg, a 51-year-old paramedic(急救医务人员) since 1984.Ten years into the job, Lanenberg received a call that reported that a man in his early 30s had fallen down in the Mall of America. When Lanenberg and his partner arrived at the scene, they found the young male face down on the ground. He had gone unconscious, making weak attempts to breathe. His wife stood beside him holding their small son in horror. They quickly rushed to defibrillate(除颤) and calm the man to keep him under control. After Lanenberg dropped the patient off at the neighboring hospital, he thought about the man and his family for a long time.Lanenberg thought he had experienced everything under the sun until one random visit to Office Max three years ago, where he met a man repeatedly walk back and forth while staring at him. As it turned out, the man was the patient he had saved 20 years earlier.“You gave me 20 years more than I ever thought I’d have,” the man said. He thanked Lanenberg repeatedly and told him he had someone he wanted him to meet. He stepped around the corner and reappeared with a 20-something-year-old man. Lanenberg instantly knew that it was the son he had seen standing by his mother all those years ago.“That day changed my life,” Lanenberg said. “Before that, everything was about work…When I talk to my beginner-training class, I tell them you never know the impact you can have on someone’s life.”4. What did Lanenberg do with the young man?A. He gave the man the first aid.B. He cured the man at the scene.C. He only sent the man to hospital.D. He took care of the man’s wife and son.5. What did Lanenberg think of the encounter with the man?A. It was unbelievable.B. It was a common routine.C. It was a matter of course.D. It was a dangerous situation.6. Why was the man thankful to Lanenberg?A. Lanenberg helped bring up his little son.B. Lanenberg donated to support his family.C. Lanenberg gave him the present happy life.D. Lanenberg taught his son to be a new doctor.7. How did the meeting change Lanenberg’s life?A. He changed his attitude to his job.B. He was rewarded with much money.C. He got a promotion to be a team leader.D. He took up teaching work to train newcomers.“There's no place like home.” This English saying has much truth in it：the best place to be is surrounded by our treasured possessions and our loved ones and with a roof over our head. And for many young adults, it's the only affordable place to stay; somewhere where they can receive first-class service from mum and dad. But this comes at a price!In some countries, it's quite traditional for people in their late teens and early 20s to live at home with their parents, but in other places, flying the nest to start their own independent life is very desirable. But there's been a growing trend, in the UK at least, for young people to return home to live---or not to leave home at all.A survey by a price comparison website found that 18% of adult children in the UK said they were moving back home because of debt, compared with 8% last year. More young people had lost their jobs, and others couldn't afford their rent compared with the previous year. So, it's easy to see why they're increasingly becoming home birds.The BBC's Lucy Hooker explains that many returning adult children enjoy home comforts. But for the 'hoteliers', that's mum and dad; the survey found the average cost to them has gone up sharply, and that they are sacrificing luxuries and holidays to look after their 'big kids'. Emma Craig from Money supermarket says “they're trying to look after their children more. If your child comes home and you see them struggling financially, you feel more awkward asking them for ren t or to contribute. It tugs on your heartstrings more.”With parents splashing out around ￡1, 886 on takeaway food, buying new furniture and upgrading their Wi-Fi for the benefit of their offspring, it's easy for the returning children to put their feet up and make themselves at home. That's before they learn a home truth---that one day it might be their own kids who'll be checking into the hotel of mum and dad!8. Which proverb might present the young British's living conditions? ______A. A lazy youth, an awful age.B. East or west, home is best.C. Two heads are better than one.D. Nothing comes wrong to a hungry man.9. Which might be the reason for the increase of home birds? ______A. The popularity of living independently.B. Looking after their old parents.C. The increase of unemployment rate.D. Their parents' financial offer.10. What's Emma Craig's attitude towards home birds? ______A. Doubtful.B. Uncertain.C. Objective.D. Understandable.11. What is the last paragraph mainly about? ______A. Returning to live with parents comes at a price.B. Parents are willing to receive their returning children.C. Flying the net is becoming popular at present.D. Home birds take it for granted to live with their parents.DPangolins (穿山甲) are the most trafficked (非法交易) mammals in the world and are facing extinction. To draw attention to these scaly (有鳞片的), anteater-like animals, a new wildlife documentary, Eye of the Pangolin, is attempting a unique way to inspire action and conservation. Partnering with the non-profit organization Pangolin Africa, the documentary was made available on YouTube in May 2019. The intention is to reach communities wherever the Internet is available, especially African communities, who live near the animal’s habitats.Over two years, the documentary crew traveled to South Africa, Ghana, Central African Republic and Gabon in search of the four unique species of pangolin, which has never been achieved before. Filmmakers Bruce Young and Johan Vermeulen say that they went into the shoot knowing relatively little about pangolins, but grew to respect and appreciate the animals. Getting close to the creatures over two years was a crash course in these secretive creatures. Johan Vermeulen said, "One thing however that might seem unimportant is that they are actually quite fussy eaters. You would think they would eat any type of ant, but they all prefer a specific type ant."Pangolins are hunted illegally across Africa for their scales, which are used for traditional medicine, and their meat. In April 2019, Singaporean customs officials conducted two separate seizures of 24 tons of pangolin scales, which equals to the death of 69,000 pangolins.Though the documentary focuses less on the trafficking of pangolins, and more on the animals in their natural habitat, the aim of the documentary is to inspire viewers around the world to call for action to end trafficking and protecting these unique creatures.Filmed on location in South Africa, Ghana, Central African Republic, and Gabon, this powerful documentary is the story of two men on a mission to get all four species of African pangolin on camera for the very first time.12．What is the purpose of the documentary?A．To study the situation of pangolins.B．To collect fund to protect pangolins.C．To raise awareness of pangolin protection.D．To propose setting up pangolin reserves.13．What is the meaning of the underlined word “fussy” in paragraph 2?A．Picky B．Messy. C．Showy. D．Heavy.14．What’s the documentary mainly about?A．The illegal trade of pangolins.B．The medical function of pangolin's scales.C．The life of pangolins in their natural habitats.D．The efforts of Pangolin Africa to save pangolins.15．Where is the text most likely from?A．A brochure. B．A diary. C．A novel D．A magazine.第二节（共5小题；每小题2.5 分，满分12.5 分）根据短文内容，从短文后的选项中选出能填人空白处的最佳选项。

2020年山东济钢高级中学高三英语三模试题及参考答案

2020年山东济钢高级中学高三英语三模试题及参考答案第一部分阅读（共两节，满分40分）第一节（共15小题；每小题2分，满分30分）阅读下列短文，从每题所给的A、B、C、D四个选项中选出最佳选项AIt was a weeknight and one of my twin daughters marched into the room, waving a book she'd finished. “Dad, why are books with science in them always about boys?” she asked.I told her that simply wasn't true; there were loads of great science fictions with girls in them. She agreed, but argued that in those stories it was the boys who were doing science, and the girls were justalong for the ride. My other daughter took her sister's side and challenged me to give an example.This left me in a difficult position. I could either go through our library to point out some wonderful examples of female-led science fictions, or just admit they were right and remain in my comfortable chair.I've been asked several times how I came up with the idea forA Problematic Paradoxand my answer is always the same: it came to me in a moment of inspiration. I like that answer because it's simple and makes me seem very creative. The fact that this explanation is not true bothers me from time to time. Here's the truth: the story wasn't my idea. It was my daughters who suggested I write something for them that had a girl doing science.My daughters were at an age when many young women turn away from STEM (science, technology, engineering, and math), believing those areas of study unfriendly or out-of-the-norm for girls. I also read about how important role models can be to young people. It's one thing to tell a person they can do something, but seeing someone like them doing that thing can be more powerful.So, I kept two guidelines for the book in mind: First, the story had to be fun for anyone, because it's as important for boys to understand that science is for everyone. Second, I wanted the main character, Nikola, to be imperfect. She should be someone with shortcomings as we all have. I think this not only makes a story more interesting to read, but also helps make it clear that the most extraordinary things can be done by ordinary people.1. What does the underlined phrase “along for the ride” in paragraph 2 probably mean?A. Entering a bike race.B. Offering vital help.C. Doing unimportant things.D. Playing the leading role.2. What do we know about the bookA Problematic Paradox1?A. Its main character is perfect.B. It is a female-led science fiction.C. It is intended to appeal to girls only.D. Its idea comes from the author's inspiration.3. Which of the following best describes the author's book?A. Serious and abstract.B. Simple and practical.C. Creative and well-organized.D. Inspiring and interesting.BIt is a question people have been asking for ages. Is there a way to turn back the aging process?For centuries, people have been looking for a “fountain of youth”. The idea is that if you find a magical fountain, and drink from its waters, you will not age.Researchers in New York did not find an actual fountain of youth, but they may have found a way to turn back the aging process. It appears the answer may be hidden right between your eyes, in an area called the hypothalamus (下丘脑). The hypothalamus is part of your brain. It controls important activities within the body.Researchers at New York’s Albert Einstein College of Medicine found that hypothalamus neural (神经的) stem cells also influence how fast aging takes place in the body.What are stem cells(干细胞)? They are simple cells that can develop into specialized cells, like blood or skin cells. Stem cells can also repair damaged tissues and organs.Dongsheng Cai is a professor at the Albert Einstein College of Medicine. He was the lead researcher in a study on aging in mice. He and his team reported their findings in the journal Nature, Cai explained when hypothalamus function is in decline, particularly the loss of hypothalamus stem cells, and this protection against the aging development is lost. it eventually leads to aging.Using this information, the researchers began trying to activate, or energize, the hypothalamus laboratory mice. They did this by injecting the animals with stem cells, Later, the researchers examined tissues and tested for changes in behavior. They looked for changes in the strength and coordination (协调) of the animals muscles. They also studied the social behavior and cognitive ability of the mice. The researchers say the results show that the treatment slowed aging in the animals, Cai says injecting middle-aged mice with stem cells from younger mice helped the older animals live longer.But these results were just from studying mice in a laboratory. If the mice can live longer, does that mean people could have longer lives? The next step is to see if the anti-aging effects also work in.4. In Paragraph 2 a “fountain of youth” is mentioned to ________.A. introduce the main topicB. show a hidden secret.C. describe scientists researchD. recommend a way to stay young5. Aging takes place in the body when _______.A. stem cells develop into specialized cellsB. there are important activities within the bodyC. hypothalamus neural stem cells fail to protect against agingD. the hypothalamus fails to repair damaged tissues and organs6. What do we know about the researchers at Albert Einstein College of Medicine from the text?A. They did experiments to see how stem cells work.B. They studied mice to find their connection with humans.C. They have found a possible way to slow the aging progress.D. They have found no changes in mice s behavior during the experiment7. What will the researchers probably do next?A. They will help some animals live longer.B. They will announce the fountain of youth doesn’t existC. They will develop products to help people live a longer life immediatelyD. They will do research to see if what they have found in mice will apply to humans.CPreventing heart disease is a topic I think about all the time, given my family history of heart disease. So last summer, I travelled toBolivia.The natives, called the Tsimane, were reported to have the healthiest hearts in the world. I wanted to learn what they could teach me about preventing heart disease.Getting to the Tsimane wasn't easy. They lived in small family groups of about 60 people along river banks. We finally found one of the villages at sunset. That night, we set up our tents in the middle of the village. Thatched huts surrounded us, with no electricity or modem conveniences.At first, I thought they mainly got their calorics from meat. However, I found food such as rice and com made up nearly 70% of their diet. The food was not processed, lacking added sugars or salts.During my stay there, I went hunting and fishing with the men and played soccer with the kids. I found the Tsimane were standing or walking nearly all of their waking hours. Men spent lots of time tracking animals. Fanning and gathering, mostly done by children and women, were all-day affairs.I also got a clear idea of how they rested. As soon as the sun went down, people returned to their huts and went to sleep. And with the call of the cock in the morning, another day began.The lifespan of the Tsimane is actually much shorter than those living in theUS. Various factors, like animal attacks and infections, bring down the lifespan. But up until the day they die, they are often very healthy. While heart disease kills thousands of Americans every year and costs nearly a billion dollars a day, the Tsimane remind us that wealth doesn't necessarily buy health.8. Why does the author pay so much attention to preventing heart disease?A. He dreams of becoming a doctor.B. He wants to teach others about the topic.C. His family members encourage him to do so.D. He was born with a high risk of heart disease.9. Which factors did the author mainly focus on in his research?A. Housing, food and cooperation.B. Diet, activity and rest.C. Physical work, social life and lifespan.D. Group size, family history and consumption10. What was the Tsimane 's sleep-wake cycle mainly based on?A. Natural sound.B. Routine activity.C. Animal behaviour.D. Natural light.11. What might the author advise us to do after his travels inBolivia?A. Take in less sugar and salt.B. Stand less and walk more.C. Eat white meat instead of red meat.D. Live in the middle of the community.DIn Copenhagen, an 8-year dream was realized when the first paid skiers took their runs down a one-third-mile course (路线)．They skied on what is possibly the greenestpower factory in the world．The factory is so clean and safe that designers were able to turn its buildings into a new center for social life．The waste-to-power factory itself opened in 2017 under the name Amager Bakke．Bjarke Ingels is the architect whosecompany came up with the idea eight years ago of designing a power plant building that would join mountain sports into its very nature．“It is the cleanest waste-to-energy power plant in the world．It is not only better for the environment, it is also moreenjoyable for the lives of its citizens.” Ingels says 97% of city people get their heating as a by-product of energy production．It comes from a system where the electricity, heating, and waste disposal (处理) are mixed into a single process．He dreams that it is also becoming an example that others can look to and say, “IfCopenhagencan do it why can' t we?"There are no hills in this island city, but now people can ski locally, while enjoying the best views ever seen of the harbor．Another thing missing hereis snow cover throughout the winter, so designers set up a kind of special "plastic grass" that provides the perfect friction (摩擦力) for downhill winter sports．In a country where 600, 000 skiers always had to travel to practice sking, to be able to finally ski in their backyard-and, all year round - is, as one skier said, “AMAZING．”The company hopes to see 300, 000 visitors enjoying the experience of Copen hill each year, with the ski slope costing $ 22 an hour or just $ 366 for a full season pass．Meanwhile, the city is one step closer to its final goal of becoming the world's first carbon-neutral city by 2025．We thinkit might be all “down hill” from here．12. How does the power factory produce electricity?A. By using oil．B. By using coal．C. By usingwind．D. By using waste．13. What' s Ingels' dream according to the passage?A. To make more tall buildings in different big cities．B. To help more skiers to ski in high mountains．C. There will be more green power factories in the world．D. More and more people will ski in the power factory．14. Where do the skiers ski in the power factory?A. On man-made snow．B. On man-made ice．C. On plastic grass．D. On real sand．15. The underlined part “it might be all 'downhill' from here" means that________.A. they will soon reach their final goalB. they will soon draw many visitorsC. they will produce more electricityD. they have difficulties reaching the goal第二节（共5小题；每小题2分，满分10分）阅读下面短文，从短文后的选项中选出可以填入空白处的最佳选项。

Filled with adventuresAs a first responder, you never know what type of situation you might walk into, or who you’ll meet along the way. That’s definitely been the case for Jeffrey Lanenberg, a 51-year-old paramedic(急救医务人员) since 1984.Ten years into the job, Lanenberg received a call that reported that a man in his early 30s had fallen down in the Mall of America. When Lanenberg and his partner arrived at the scene, they found the young male face down on the ground. He had gone unconscious, making weak attempts to breathe. His wife stood beside him holding their small son in horror. They quickly rushed to defibrillate(除颤) and calm the man to keep him under control. After Lanenberg dropped the patient off at the neighboring hospital, he thought about the man and his family for a long time.Lanenberg thought he had experienced everything under the sun until one random visit to Office Max three years ago, where he met a man repeatedly walk back and forth while staring at him. As it turned out, the man was the patient he had saved 20 years earlier.“You gave me 20 years more than I ever thought I’d have,”the man said. He thanked Lanenberg repeatedly and told him he had someone he wanted him to meet. He stepped around the corner and reappeared with a 20-something-year-old man. Lanenberg instantly knew that it was the son he had seen standing by his mother all those years ago.“That day changed my life,”Lanenberg said.“Before that, everything was about work…When I talk to my beginner-training class, I tell them you never know the impact you can have on someone’s life.”4. What did Lanenberg do with the young man?A. He gave the man the first aid.B. He cured the man at the scene.C. He only sent the man to hospital.D. He took care of the man’s wife and son.5. What did Lanenberg think of the encounter with the man?A. It was unbelievable.B. It was a common routine.C. It was a matter of course.D. It was a dangerous situation.6. Why was the man thankful to Lanenberg?A. Lanenberg helped bring up his little son.B. Lanenberg donated to support his family.C. Lanenberg gave him the present happy life.D. Lanenberg taught his son to be a new doctor.7. How did the meeting change Lanenberg’s life?A. He changed his attitude to his job.B. He was rewarded with much money.C. He got a promotion to be a team leader.D. He took up teaching work to train newcomers.“There's no place like home.” This English saying has much truth in it：the best place to be is surrounded by our treasured possessions and our loved ones and with a roof over our head. And for many young adults, it's the only affordable place to stay; somewhere where they can receive first-class service from mum and dad. But this comes at a price!In some countries, it's quite traditional for people in their late teens and early 20s to live at home with their parents, but in other places, flying the nest to start their own independent life is very desirable. But there's been a growing trend, in the UK at least, for young people to return home to live---or not to leave home at all.A survey by a price comparison website found that 18% of adult children in the UK said they were moving back home because of debt, compared with 8% last year. More young people had lost their jobs, and others couldn't afford their rent compared with the previous year. So, it's easy to see why they're increasingly becoming home birds.The BBC's Lucy Hooker explains that many returning adult children enjoy home comforts. But for the 'hoteliers', that's mum and dad; the survey found the average cost to them has gone up sharply, and that they are sacrificing luxuries and holidays to look after their 'big kids'. Emma Craig from Money supermarket says “they're trying to look after their children more. If your child comes home and you see them struggling financially, you feel more awkward asking them for rent or to contribute. It tugs on your heartstrings more.”With parents splashing out around ￡1, 886 on takeaway food, buying new furniture and upgrading their Wi-Fi for the benefit of their offspring, it's easy for the returning children to put their feet up and make themselves at home. That's before they learn a home truth---that one day it might be their own kids who'll be checking into the hotel of mum and dad!8. Which proverb might present the young British's living conditions? ______A. A lazy youth, an awful age.B. East or west, home is best.C. Two heads are better than one.D. Nothing comes wrong to a hungry man.9. Which might be the reason for the increase of home birds? ______A. The popularity of living independently.B. Looking after their old parents.C. The increase of unemployment rate.D. Their parents' financial offer.10. What's Emma Craig's attitude towards home birds? ______A. Doubtful.B. Uncertain.C. Objective.D. Understandable.11. What is the last paragraph mainly about? ______A. Returning to live with parents comes at a price.B. Parents are willing to receive their returning children.C. Flying the net is becoming popular at present.D. Home birds take it for granted to live with their parents.DPangolins (穿山甲) are the most trafficked (非法交易) mammals in the world and are facing extinction. To draw attention to these scaly (有鳞片的), anteater-like animals, a new wildlife documentary, Eye of the Pangolin, is attempting a unique way to inspire action and conservation. Partnering with the non-profit organization Pangolin Africa, the documentary was made available on YouTube in May 2019. The intention is to reach communities wherever the Internet is available, especially African communities, who live near the animal’s habitats.Over two years, the documentary crew traveled to South Africa, Ghana, Central African Republic and Gabon in search of the four unique species of pangolin, which has never been achieved before. Filmmakers Bruce Young and Johan V ermeulen say that they went into the shoot knowing relatively little about pangolins, but grew to respect and appreciate the animals. Getting close to the creatures over two years was a crash course in these secretive creatures. Johan V ermeulen said, "One thing however that might seem unimportant is that they are actually quite fussy eaters. You would think they would eat any type of ant, but they all prefer a specific type ant."Pangolins are hunted illegally across Africa for their scales, which are used for traditional medicine, and their meat. In April 2019, Singaporean customs officials conducted two separate seizures of 24 tons of pangolin scales, which equals to the death of 69,000 pangolins.Though the documentary focuses less on the trafficking of pangolins, and more on the animals in their natural habitat, the aim of the documentary is to inspire viewers around the world to call for action to end trafficking and protecting these unique creatures.Filmed on location in South Africa, Ghana, Central African Republic, and Gabon, this powerful documentary is the story of two men on a mission to get all four species of African pangolin on camera for the very first time.12．What is the purpose of the documentary?A．To study the situation of pangolins.B．To collect fund to protect pangolins.C．To raise awareness of pangolin protection.D．To propose setting up pangolin reserves.13．What is the meaning of the underlined word “fussy” in paragraph 2?A．Picky B．Messy. C．Showy. D．Heavy.14．What’s the documentary mainly about?A．The illegal trade of pangolins.B．The medical function of pangolin's scales.C．The life of pangolins in their natural habitats.D．The efforts of Pangolin Africa to save pangolins.15．Where is the text most likely from?A．A brochure.

2019-2020学年山东济钢高级中学高三英语三模试题及参考答案

2019-2020学年山东济钢高级中学高三英语三模试题及参考答案第一部分阅读（共两节，满分40分）第一节（共15小题；每小题2分，满分30分）阅读下列短文，从每题所给的A、B、C、D四个选项中选出最佳选项AThe last thing Caitlin Hipp would have expected as she prepared to turn 28 years old was to be living at homewith her parents. But through working as a part-time skating instructor and restaurant server, she isn't able to earn enough to live anywhere other than home.To some degree, multigenerational households have always been a part of American life. However, the number of young adults who have been moving back in with their parents — or never leaving home in the first place — has been growing steadily.UBS Financial Services released a report that even suggests one reason for the growing number of young adultsstill living at home could be that their family doesn't want them to leave.The report shows that 74 percent of millennials (千禧一代)get some kind of financial support from their parents after college. It finds that millennials have redefined the ties that connect parents and children. Millennials see their parents as peers,friends and instructors. Nearly three quarters talked with their parents more than once a week during college. In return, their parents happily provide financial support well into adulthood, helping fund everything for them.Stuart Hoffman, chief economist for the PNC Financial Services Group in theUS, said the number of young adults striking out on their own fell during the Great Recession. Although job growth for millennials since 2014 has improved, that doesn't necessarily mean that millennials are starting to fly the nest. He said, “They may like living at home and being able to save money.“ There's no doubt it has held back household formation and purchases of things people spend money on related to household formation and perhaps related to child-raising," Hoffman explained. "But they are probably traveling more and eating out more if they don't have a house expense or marriage. I don't know if it represents a change in moral values. But it's much more common for adult children to live in their parents’ homes because it's becoming part of the culture.1. What can we learn from the UBS Financial Services' report?A. Millennials are on good terms with their parents.B. Millennials are financially independent after college.C. Parents are unwilling to give their young adults allowance.D. Parents want their kids to stay with them forever.2. What does Hoffman think of young adults' living at home?A. It increases the consumption of household products.B. It may continue despite job growth.C. It is a sign of shift in moral values.D. It is new in American culture.3. What is the author's purpose of writing this passage?A. To introduce millennials' living habits.B. To stress the importance of financial independence.C. To explain why American young adults still live at home.D. To inform people of a social trend in theUS.BA new look for technology, Solestrom’s new high-tech swimsuits promise to stand out all summer long. First in their new products is Solestrom’s new SmartSwimCMUV Smart Bikini featuring a smart UV meter.The bikini collects UV information through a smart fabric belt and reports the UV index to the wearer with 0.01 exactness. The electronic parts are neatly built into the removable belt, and can be worn even underwater. Next in the list is a lower cost cousin, the SmartSwimCMUV Index Detector Bikini, which has UV sensitive beads that change color1 with the level of UV intensity. The reading gives more of a range rather than an exact number, but for those who simply need to know if the UV is low, moderate or high, this bikini fits the bill.It is now available in Banana Split, more color1 s may become available later in the season. And finally, what could be better than a beach tote with built in energy source? No need to suffer dead batteries in your MP3, just plug them into your Solar Powered Beach Tote for on-the-go mobile charging. This beach tote combines fashion and functionality all in one, lightweight and roomy beach accessory. A built in solar panel charges fully most small electronics in only 2-3 hours of sunlight. Pauline Butler, Media Relations Manger at Solestrom states “the concept of blending fashion and technology is growing at amazing rate, and we are right on the leading edge. Our products are new, creative and meet the need of the young and environmentally conscious crowd.’’Solestrom’s SmartSwinirCMproducts retail from $98. 99- $189. 99，and can be found in their online store, Solestrom. com.4. What is the passage mainly about?A. Famous Solestrom and its Products.B. Fashionable and Functional Beach Tote.C. Smart swimsuits and Solar Powered Beach Tote.D. Where and How to Buy SmartSwirn and the Beach Tote.5. Why are UV sensitive beads used in the SmartSwirnCMUV Index Detector Bikini?A. To give an exact number.B. To know if the UV is low, moderate or high.C. To change color1 with the level of UV intensity.D. To improve the equality of the UV Index Detector Bikini.6. What can we know about Solar Powered Beach Tote?A. Its parts are fixed in the belt.B. It combines lightweight and functionality.C. It can tell the weaver the level of UV intensity.D. It saves people from worrying about dead batteries in their MP3.7. Who will prefer the new products mentioned in the text?A. The young people and the environmentalists.B. People who like to travel all over the world.C. People who love to buy goods online.D. People interested in the latest bag.CIn 1990, Hal Donaldson was 23 years old, fresh out of college and found himself in Calcutta, India, where he was asked to interview Mother Teresa.Donaldson says about the great woman famed for feeding the hungry, “She wasn't wearing shoes and her ankles were swollen. She sat down with me and was very polite.” After the interview, Mother Teresa asked him, “What are you doing to help the poor?” Donaldson admitted that he was young and wasn't focused on helping others. With a smile on her face, Mother Teresa said, “Everyone can do something.”Those words deeply struck Donaldson and forced him to face some hard truths about himself.Hal Donaldson grew up in the San Francisco Bay area. When he was 12 years old, his parents were hit by a drunk driver; his father died, and his mother was seriously injured. To make ends meet, they went on welfare. Donaldson says, “I had holes in my shoes and clothes. When you're teased at school for that, you just want to escape.”He managed to do just that. Donaldson got into college and turned his focus to making money for himself Hesays, “I was just trying to find my way out of insignificance. However, it's easy to overlook others along the way. I was the guy that would see a homeless person and cross the street, so I didn'thave to confront (面对) him. My focus was on climbing to the top instead of helping those trying to climb with me.”Donaldson returned home from India with a different thought. He traveled to eight cities in America and stayed on the streets and listened tostories of the homeless. “My heart broke,” he says. “I knew I could no longer just live for myself.”Inspired by Mother Teresa's words and the stories he'd heard across America. Donaldson loaded a pick-up truck with $300 worth of groceries and handed them out to anyone who needed help. In 1994, Donaldson created the nonprofit organization, Convoy for Hope, which works with communities across America and around the world. Their work focuses on feeding children, women's empowerment, helping farmers and disaster services.8. What did 23-year-old Hal Donaldson do in India?A. He attended an interview for a college.B. He fed the hungry with Mother Teresa.C. He interviewed Mother Teresa.D. He did something to help the poor.9. What can we learn about Hal Donaldson from paragraph 4?A. He was born with disability.B.

Casual.11. How did Hal Donaldson change after he returned home from India?A. He preferred traveling to volunteering.B. He suddenly fell in love with journalism.C. He turned his focus to living for himself.D. He gradually devoted himself to helping others.DYellowstoneNational ParkbecameAmerica's first national park in 1872. The National Park Service was formed 44 years later in 1916.Yellowstone, which is mostly in the state of Wyoming, is considered an example of the success of the National Park System.Humans have been present in Yellowstone for more than 11,000 years.Yellowstone contains beautiful mountains, deep canyons(峡谷), lakes and rivers.The nameYellowstonecomes from the river running through the area. At first known as Rock Yellow River, it became known as theYellowstoneRiver.Yellowstoneis host to many different species of plants. However, the park is most distinctive because of what lies underneath it. It sits on top of an ancient super volcano, known as The Yellowstone Caldera. The caldera is 48by 72 kilometers. And it remains an active volcano.It is believed that the last time the volcano erupted was one half million years ago. The area has had three major eruptions in the last three million years.Experts say it may erupt again in another 1,000 to 10,000 years. But each year, there are thousands of earthquakes atYellowstone. Most are too small to be felt by people visiting the park.Yellowstoneis filled with the beauty of many hot water springs. hot water and gasses are trapped under the earth. they rush to the surface in the form of hot water and steam.Old Faithful is The most famous one .Iterupts about every hour or hour and a half. The eruption can last from one and a half minutes up to 5 minutes. The amount of hot water it expels（排出）in that time can be as much as 31,000 liters or more.In addition to its beauty and wonder, Yellowstone is an animal sanctuary（保护区）. It is home to the largest group of wild animals in theUnited States. As you travel through the park, you can sometimes see them in their natural habitat and hear their calls .12. What wasYellowstonenamed after?A. RockYellow RiverB. The amazing mountains.C. The stones with yellow color1D. The first discovery inwyoming.13. What makesYellowstonequite unique?A.

2020届山东济钢高级中学高三英语三模试题及参考答案

2020届山东济钢高级中学高三英语三模试题及参考答案第一部分阅读（共两节，满分40分）第一节（共15小题；每小题2分，满分30分）阅读下列短文，从每题所给的A、B、C、D四个选项中选出最佳选项AIn his 402nd anniversary year, Shakespeare is still rightly celebrated as a great language master and writer. But he was not the only great master of play writing to die in 1616, and he is certainly not the only writer to have left a lasting influence on theater.While less known worldwide, Tang Xianzu is considered one of Chinas greatest playwrights and is highly spoken of in that country of ancient literary and dramatic traditions.Tang was born in 1550 inLinchuan,Jiangxiprovince. Unlike Shakespeare's large body of plays,poems and sonnets (十四行诗), Tang wrote only four major plays: The Purple Hairpin, Peony Pavilion (《牡丹亭》), A Dream under the Southern bough, and Dream of Handan. The latter three were constructed around a dream narrative, a way through which Tang unlocked the emotional dimension of human desires and ambitions and explored human nature beyond the social and political limits of that time.Similar to Shakespeare, Tang's success rode the wave of a renaissance (复兴) in theater as an artistic practice. As in Shakespeare'sEngland, Tang's works became hugely popular inChinatoo. During Tang'sChina, his plays were enjoyed performed, and changed. Kunqu Opera, a form of musical drama, spread from southernChinato the whole nation and became a symbol of Chinese culture. Combining northern tune and southern music, kunqu Opera was known for its poetic language, music, dance movements and gestures. Tang's works benefited greatly from the popularity of kunqu Opera, and his plays are considered classics of kunqu Opera.While Tang and Shakespeare lived in a world away from each other, there are many things they share in common, such e humanity of their drama, their heroic figures, their love for poetic language, a lasting popularity and the anniversary during which we still celebrate them.1. Why is Shakespeare mentioned in the first paragraph?A. To describe Shakespeare's anniversary.B. To introduce the existence of Tang Xianzu.C. To explain the importance of Shakespeare.D.

Mollie, 11, has required hospital treatment several times while Jake Says he always finds breathing more difficult when there is heavy traffic. Air quality has an enormous impact on their lives and both noticed a marked improvement during the spring lockdown because of the epidemic (疫情). Jake said, “During lockdown there was a noticeable difference in air quality. I didn't suffer any asthmatic attacks during that period. These days you can feel the effects.”However, under current COVID-19 restrictions in the UK this winter, many people probably will have to work from home. The Energy and Climate Intelligence Unit (ECIU) says while emissions (排放) have dropped this year because we've been travelling less and doing less, the expected use ofgas boilers to provide heating and hot water could rise by more than half.Heating accounts for nearly 37% of the UK's total carbon emissions. Modelling by the ECIU suggests a 56% increase in boiler usage this winter resulting in a 12% increase in emissions of carbon. The ECIU says that's enough to offset the last two years' worth of progress on reducing traffic emissions.Jess Ralston, author of the analysis for the ECIU, said, “Working from home and having increased gas use in the home could be really critical for air pollution and also climate change. The way we heat our homes needs to change if we are to get to net zero by 2050.”Jess Ralston said, “The increase in pollution from gas boilers expected this winter provides a graphic illustration (图解) of their forgotten role in air pollution. And it is a role set to continue without practical policies to decarbonize home heating. ”The government is set to publish its Heat and Buildings Decarbonisation Strategy in a few weeks which is expected to give details on plans to try to switch British homes to cleaner sources of heat.4. How did the spring lockdown in the UK affect Jake?A. He was cured of his asthma.B. He had to go to hospital for retreatment.C. He suffered a noticeable difficulty in study.D.

Air pollution will get worse this winter.C. People may have to work from home longer.D. There is less energy for gas boilers in winter.6. What would Jess Ralston agree with?A. People prefer to work from home in winter.B. The government failed to protect the environment.C. People tend to ignore the harmful effect of home heating.D. The climate has suffered a lot from the epidemic this year.7. How to improve air quality during winter according to Jess Ralston?A. A warmer winter season.B. Less and less gas boilers.C. Practical plans from the government.D. Improved awareness of cutting down pollution.CIt was once considered an important status symbol ---but having a home phone is increasingly seen asa white elephant. New figures show that one in five households no longer bother with a landline（固定电话），and almost a third of those that do never actually use it.The vast majority of people who still have a home phone ——72 percent ——say they only have it because it is part of their broadband package.But that's not the only reason to desert the home phone - 20 percent of those surveyed said that they were fed up with the number of cold calls and would-be scammers（诈骗者）.Digital media expert Dr. Elinor Carmi said there was a generational and social divide in phone use. She explained："If you,re young and have the mobility to go outside, you would rely on a mobile phone. But if you are older, disabled and perhaps poorer, our research shows you're more likely to use a landline. If you are richer, you will have access to more smart devices --- a smart TV, smartphone or laptop. But the poorer you are --- or if youare older, your use of these devices is more limited.”Last year, research from regulator Ofcom found that the amount of time spent on landline calls annually in theUKhad halved over just six years, to 54 billion minutes. The new study also showed that more than a quarter of households have decided to find a broadband provider that does not charge for their unused landline, but only six percent have done so.8.

Different choices of phonesDIvrea is a town in the Piedmont province of northern Italy. It is known for its localcarnival（狂欢节）organized in February.The main part of the carnival is the famous Battle of the Oranges (La battaglia delle arance). The Battle includes nine teams who throw oranges at each other during three carnival days – Sunday, Monday and Tuesday.Oranges were not always used in the battle. In the middle ages people used beans. Twice a year the local feudal lord gave a pot of beans to the poor families who, as sign of rebellion, threw them out of their homes. Laterbeans became part of carnival as sort of “ammunition” for throwing at people passing by.It is still not known why exactly people started using oranges. It is believed that the origin for this tradition is in the mid 19th century. The legend says that local girls, standing on balconies, started to throw some oranges, together with confetti,lupins(白羽扇豆)and flowers, onto the parade carriages. The girls actually wanted to draw attention of boysin the carriages. Boys “answered” by throwing some objects back at girls. Little battle started that way.Battle of the Oranges got strict rules after the World War II. The battles are organized on town's squares. The battles are fought between teams in carriages (symbolizing local the guards of localtyrant(恶霸)) and the teams walking beside those carriages (symbolizing rebellious people of Ivrea).Oranges for the event are brought from the island of Sicily. The oranges used are of low quality, not suitable for humans. About 270,000 kilograms of oranges are used each year.The carnival ends with a silent march on the night of “Fat Tuesday”. The Carnival "general" says goodbye to everyone with the phrase "See you next Fat Thursday at 1 p.m."Special prizes are awarded to three best foot teams, three carriages drawn by two horses and three carriages drawn by four horses. Different elements are judged like for example throwing ability, fair play or decoration of carriages.12.

That’s what experts in human interaction are debating after a new Stanford University survey has been published.According to the study, the more time people spend online, the less they can spare for real-life relationships with family and friends. The researchers asked 113 people about the Web’s influence on daily activities. 36％of those people are online for more than five hours a week.” As Internet use becomes more widespread, it will have an increasingly isolating (孤立的) effect on society,” says Robert Kraut, one of the researchers.Scholars and Web lovers criticized the study for stretching its data to make the “isolating” point. While 13％of regular Web users admitted the loss of time with loved ones, 60％reported watching less TV. The survey also shows that E-mail is the most popular online activity. If some of webheads (网虫)spend what was once passive TV time keeping company with friends via E-mails, “that’s a move toward greater connectedness,” says Paul Resnick, a professor at the University of Michigan.Thisisn’t the first claim that the Web should be criticized. A 1998 report monitored 73 Pittsburgh-area families’ Net use for a year. People who used the Internet more “talked less to family members and reported being lonelier and more depressed.” says Robert Kraut.“It’s true that there have been big declines in social connectedness over the past decades, but those declinesbegan before the Internet was invented,” says Thomas Putnam.As Amitay Etzioni says, the Internet gives us a different kind of social life—not better or worse than before, but just different.4. Who claimed that the Web had negative influence?A. Paul Resnick.B. Robert Kraut.C. Thomas Putnam.D. Amitay Etzioni.5. The underlined word “This” in Para.4 refers to .A. the opinion expressed in Bowling AloneB. the survey made by the University of MichiganC. the conclusion in a report written in 1998D. the study conducted by Stanford University6. From the passage we learn that .A. watching TV used to take time away from staying onlineB. the Web was blamed more than once for causing an isolating effectC. 36％ofweb users spend more than five hours a week onlineD. the Web has the same influence as telephones and televisions7. The passage mainly discusses .A. how we can make a better use of the InternetB. how declines in social connectedness appearC. whether the Internet causes an isolating effectD. what a different life the Internet brings to usCDistinguished Baltimore artist John D. Ferguson died Sept 16. The Catonsville resident was 81.“His artist eye was in everything he did. His life was art and his family,” said Jennifer C. Jackson, who was Mr. Ferguson's friend for nearly three decades.” He was a lovable man who was always willing to talk about any topic he was interested in. At shows, people would go crazy for his work,” Ms. Jackson said. “He was also an enthusiastic sailor who loved nothing more than being on the water.” “His sculptures were just memorable,” said Mr. Lund, a Washingtonian. “I used to say, ‘Ferguson, I don't think you know how to do anything that is less than monumental.’”Mr. Ferguson earned a bachelor's degree in 1961 at Holy Cross University, where he developed an interest inpainting. He served in the Army for two years until being discharged in 1963, and after studying briefly at the Boston Museum School, registered at the Chicago Art Institute, where he studied until 1966, when he entered the University of Illinois Chicago, where he obtained a bachelor's degree in 1966 in fine arts. Mr. Ferguson developed his interest and skills as a sculptor after moving to Baltimore to do further studies at the Maryland Institute College of Art's Rinehart School of Sculpture, from which he graduated in 1971 with a master's degree in fine arts.“Over the years my work has moved gradually in the direction of elegance and simplicity,” Mr. Ferguson wrote in his artist statement. “Heavy, bulbous forms have been replaced by dancing, winglike forms. The welding process and respect for the qualities of the materials are interrelated and affect the final piece. “Most of the sculptures that are pictured in my works are made from steel, silicon bronze, and to Cor-Ten steel; shaped to create these beautiful and unique pieces of art. As you can see, my sculptures range in size anywhere from 12 inches to 30 feet or larger.”Through the years, his work found its way into such major public and private collections. “They encourage optimism, for they show strength and affirmation; there's nothing negative, depressing or anxiety-ridden about them”, wrote the late art critic John Dorsey in a 1997 exhibition review.8. What did Mr. Lund think of Ferguson?A. Likeable.B. Ordinary.C. Unwelcome.D. Interesting.9. What did Mr. Ferguson do first after serving in the army?A. He studied at the Boston Museum School.B.

An even larger scale than before.B. The material comprised of metalsC. The shape of elegance and simplicity.D. Welding process as well as material quality.11. Which of the following is a suitable title for the text?A. A stylish, stubborn old manB. Sculptures towering into the cloudsC. JohnD. Ferguson—a famous sculpturer D. The evolution of the sculptural styleDThe annual 3-to-4-millimeter rise in sea levels is expected to impact many coastal communities in the coming decades. However, few are as defenceless as the Republic of theMaldives, a collection of more than a thousand picturesque islands in theIndian Ocean. NASA researchers believe that parts of what is “arguably the lowest-lying country in the world” will become uninhabitable by 2050, due to wave-driven flooding and limited freshwater. To fight the unavoidable, the government recently revealed plans for the world's first 'true' floating island city.The aptly-named Maldives Floating City (MFC) is the brainchild of Dutch Docklands, a global leader in floating infrastructure (基建). According to the March 13, 2021, announcement, the new city will be constructed on a 200-hectare lagoon (环礁湖) located just 10 minutes by boat from the Maldivian capital, Male. It will initially consist of a thousand waterfront residences, arranged in a series of honeycomb-like maze rows. The developers plan to add hotels, restaurants, shops, and even a school and a hospital in the near future. The floating structures. will be attached to the surrounding islands, which will form a base and provide protection from high tides.Maldive officials aim to make MFC as self-sufficient as possible. Freshwater storage will provide drinking water for residents, while floating solar blankets and agriculture fields will take care of their energy and food needs.“ThisMaldivesFloatingCitydoes not require any land rehabilitation, therefore has a minimal impact on the coral reefs,” explains Mohamed Nasheed, Speaker of Parliament. “What's more, giant, new reefs will be grown to act as water breakers. In theMaldives,we cannot stop the waves, but we can rise with them.”Construction of the revolutionary city is expected to begin in 2022 and be completed in phases over the next five years. If successful, it will provide a blueprint for other countries facing a similar situation.12. Why doesMaldivesdecide to build MFC?A. It is the lowest-lying country.B. It will be flooded soon.C.

The barriers to the construction.14. What can we infer from the underlined words?A. MFC will keep waves away.B. MFC will make use of waves.C. MFC will adjust to the waves.D. MFC will work as water breakers.15. What's the writing purpose of this passage?A. To introduce a construction program.B. To appeal to people to protect nature.C. To seek international help forMaldives.D. To report the achievement of a city plan,第二节（共5小题；每小题2分，满分10分）阅读下面短文，从短文后的选项中选出可以填入空白处的最佳选项。
