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。

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. 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届山东省济钢中学高三下学期3月份质量检测物理试题(解析版)
山东省济钢中学2020届高三下学期3月份质量检测试题一、单项选择题：本题共8小题，每小题3分，共24分。
在每小题给出的四个选项中，只有一项是符合题目要求的。
1.如图，为氢原子能级图；金属钾的逸出功为2.25eV，则下面有关说法正确的是A. 处于基态的氢原子能吸收13.0eV的光子后跃迁至n=3能级B. 大量处n=4能级的氢原子向低能级跃迁时，最多可辐射出5种不同频率的光C. 用处于n=3能级的氢原子向低能级跃迁所辐射出的各种色光照射金属钾，都能发生光电效应D. 用大量处于n=4能级的氢原子向低能级跃迁所辐射出的光照射金属钾，所产生光电子的最大初动能为10.5eV『答案』D『解析』『详解』A．用能量为13.0eV的光子照射，基态的氢原子若吸收13eV的能量，则能量值为－0.6eV，氢原子没有该能级。
所以不能使处于基态的氢原子跃迁，故A错误；B．大量处于n=4能级的氢原子，最多可以辐射出2C=6种不同频率的光，故B错误。
4C=3，知该群氢原子可能发射3 C．现有一群处于n=3能级的氢原子向低能级跃迁，根据23种不同频率的光子，但是n=3能级跃迁到n=2能级的光子能量小于2eV，所以能使该金属发生光电效应的频率共有2种，故C错误；D．n=4能级的氢原子跃迁到基态时，释放光子的能量E=E4－E1=12.75eV再根据光电效应方程式得光电子的最大初动能为E k =E －W 0=12.75eV －2.25eV=10.5eV故D 正确。
故选D 。
2.我国将于2020年完成35颗卫星组网的“北斗”全球卫星导航定位系统，该系统由5颗静止轨道卫星和30颗非静止轨道卫星构成.30颗非静止轨道卫星中有21颗是中轨道卫星，中轨 道卫星的轨道高度约为21500km,静止轨道卫星的高度约为36000km ，已知地球半径为6400km. 关于北斗导航卫星，下列说法中正确的是A. 中轨道卫星的线速度约为7.9km/sB. 中轨道卫星的运行周期比静止轨道卫星周期大C. 中轨道卫星的向心加速度比静止轨道卫星的向心加速度大D. 静止轨道卫星绕地球运行的角速度比月球绕地球运行的角速度小『答案』C『解析』『详解』A ．由于中轨道卫星的半径大于地球半径，故中轨道卫星的线速度小于第一宇宙速度7.9km/s ，故A 错误；B ．由2224GMm m r r T π=，得2T = ．静止轨道卫星轨道半径大于中轨道卫星轨道半径，所以静止轨道卫星的运行周期大于中轨道卫星的运行周期，故B 错误C ．由2GMm ma r = 得2GM a r = ．中轨道卫星的向心加速度比静止轨道卫星的向心加速度大，故C 正确．D ．由22GMm m r r ω= 得ω=．静止轨道卫星绕地球运行的角速度比月球绕地球运行的角速度大，故D 错误．3.2019年8月11日超强台风“利奇马”登陆青岛，导致部分高层建筑顶部的广告牌损毁。
