山西省大同市2019-2020学年高一上学期语文期末检测试题

山西省大同市2019-2020学年高一上学期语文期末检测试题一、现代文阅读1.阅读下面的文字,完成下面小题。
材料一:往返4000多公里的超远距离通信,时延36毫秒内,依靠虚拟仿真和5G技术,南京航空航天大学教授田威把曾经只能是空想的飞机制造实验教学变成了现实——4月9日,以“识变、应变、求变”为主题的中国慕课大会在京启幕。
在现场教学展示环节,田威用一根网线串起了一场三地三校同时完成的飞机大部件装配实验。
作为互联网发展的产物,慕课自诞生起就被寄予了打破传统教育时空界限和学校围墙、催生新的教育生产力的厚望。
慕课带来的教学组织形式、学习方式和管理模式的变革,正为不同层次、不同类型的受教育者提供个性化、多样化、高质量的教育服务。
会上,教育部副部长钟登华透露,如今,我国慕课数量和应用规模居世界第一,共计2亿多人次“打卡”慕课学堂,较2017年增长2.7倍,上线慕课数量约12500门,增加近3倍;国家精品在线开放课程数量增至1291门,增加1.6倍。
同时,覆盖所有专业门类的慕课体系正在建立。
(摘编自《中国慕课:跑出速度创新标准》,《光明日报》2019年4月11日)材料二:朱春俐在《国内慕课学习的调查研究》一文中,选取了六大慕课平台上共1051门课程作为观察样本,观察其所属专业学科。
又从1051门样本课程中选取出各平台上关注度最高的5门热门课程,共计28门课程(其中有2门重复课程),观察其所属专业学科。
得到以下信息,如图:(摘编自朱春俐《国内慕课学习的调查研究》)材料三:据报道,今年,教育部将出台《在线开放课程建设与应用管理办法》,推进“亚欧会议慕课网络行动”,充分借助“互联网+教育”“智能+教育”,支持国内慕课平台横向联合,推动更多慕课上线国际著名平台。
经过量的积累,我国慕课已经进入质的提升阶段,但是还存在诸多问题。
许多慕课平台堆积大量教学视频资源,与传统课堂的“满堂灌”并无本质差异。
对此,授课者必须做到以学习者的需求为中心,明确教学目标、优化教学设计。

2019-2020学年山西大同大学浑源师范分校高三英语期末考试试题及参考答案

2019-2020学年山西大同大学浑源师范分校高三英语期末考试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. To suggest the less popularity of Tang Xianzu.2. What's possibly one of the main theme of Tang's works?A. Social reality.B. Female dreams.C. Human emotions.D. Political environment.3. What does the author mainly tell us in Paragraph 4?A. The influence of Kunqu Opera on Tang's works.B. Tang's success in copying Shakespeare's styles.C. The way Kunqu Opera became a symbol of Chinese culture.D. Tang's popularity for his poetic language and music.BMy first week working in a restaurant, one of the servers said something that stuck with me: Everyone should work in a restaurant for at least a year. At the time, I didn't get it, but I took the advice to heart and worked in restaurants on and off for the next eight years. Before realizing it, I mastered many important skills, one of which is communication skill.When I was little, I was so shy that I used to hide behind my mom whenever someone spoke to me. And when I first started in restaurants, I had two personalities: Restaurant Lizzy and Home Lizzy. It was easier to pretend to be a different person while at work, since it was so different from who I actually was. But gradually, the skills I learned working in restaurants helped Home Lizzy come out of her shell in the real world.When you work in a restaurant, you don't have the luxury of hiding behind your parents to avoid talking to people. I'm still 110% an introvert, but restaurant work helped me communicate. Working in a restaurant not only helped me speak clearly, deliberately and directly but also taught me how to talk about almost everything. Some guests don't want their servers to interact too much with them, and that's fine. But some sit at the bar simply to chat with you. You learn how to judge your guests' level of interest in communicating with you, and how to exit a conversation at the appropriate time.My restaurant work is something that I'm most proud of and I know I wouldn't be the person I am today without those eight years of experience. If you're still on the fence about working in a restaurant for that long, start with one year. I doubt that you'll look back.4. What did the writer think of the server's words?A. Impressive.B. Ridiculous.C. Amusing.D. Logical.5. What do we infer from Paragraph 2?A. The writer tried different jobs.B. The writer became more sociable.C. The writer used an invented name.D. The writer had a hard time at work.6. Which of the following best describes the writer's restaurant work?A. Boring.B. Relaxing.C. Worthwhile.D. Unchallenging.7. What message does the writer try to convey in this passage?A. A strong-willed soul can reach his goal.B. Things are difficult before they are easy.C. Communication skills advance your career.D. Restaurantwork helps to achieve a better self.CThe idea came to him when he least expected it. Alvin Irby was at a barbershop when he saw one of his former students sitting in the shop with a bored look on his face. That’s when Irby realized that by pairing barbershops and books, he might be able to inspire young boys to read.Alvin Irby, a former kindergarten and first-grade teacher, knows how important it is for young children to read. He also knows that young boys in particular often don’t have adult male role models who inspire them to read. “Many young boys may literally never see a man reading in school during the years when they’re learning to read because there are so few male elementary school teachers,” Irby toldMashable.That’s where the barbershops come in. Four years ago, Irby launched Barbershop Books as a way to not just get books into the hands of young boys, but also to create community reading spaces in a place where kids go frequently. Since itsinceptionin 2013, the program has created kid-friendly reading spaces in 50 barbershops in 12 states throughout the United States.Irby isn’t the first person to see the connection between barbershops and books and boys. Hair stylist Courtney Holmes, launched a program a few years ago offering free haircuts to kids as long as they read to him while he cuts their hair.That’s the kind of environment that Irby wants to promote with his program. The reading spaces created by Barbershop Books help to spark an interest in books by showing kids that reading is about more than just spelling and vocabulary skills, it’s about making reading a low-stress activity that can help them relax, laugh and have fun.“Our belief is that if we can create positive reading experiences early and often for young boys, then they will choose to read for fun,” Irby noted, adding, “This is really what Barbershop Books is about, getting young boys to say three words: I’m a reader.”8. What happened to Alvin when he was at a barbershop?A. He found it easy for young people to get bored.B. He offered a barbershop to his former student.C. He thought of a way to encourage young readers.D. He realized the importance of reading for young boys.9. What is the function of Barbershop Books?A. To attract more customers who love films.B. To provide free haircuts to book lovers.C. To show the influence of reading on children.D. To create a reading environment fbr children.10. It can be inferred from the passage that ________.A. reading is a low-stress activity that is relaxingB. Barbershop Books is only suitable for young boysC. Irby attaches great importance to school educationD. Barbershop Books can arouse (引起) young people’s interest in reading11. What does the underlined word “inception” in the 3rdparagraph mean?A. discovery.B. success.C. popularity.D. beginning.DZaki was small for his twelve years, and he was angry being treated as a child. Farid, his older brother, had been looked upon as a man long before he was Zaki’s age. Every day Farid and the other young Bahraini men went out in their wooden boats to dive for oysters (牡蛎). Many times Zaki begged to go along, but Faridalways refused to let him.So every day Zaki would go to the shallow water to practice. His grandfather, a former diver, would watch him and advise him. All morning, Zaki would practice diving beneath the waves. Every afternoon, again and again he would go underwater and hold his breath. With each day’s practice, his diving improved and he could hold his breath a little while longer. Soon Zaki felt as much at home in the water as he did out of it.Zaki rose early one day. He wanted to compete with his brother. They dived beneath the waves. Zaki opened his eyes and found himself looking into his brother’s face. Farid was smiling with confidence. Slowly, the smile was disappearing from Farid’s face. As more seconds passed, a worried look appeared on Farid’s face. Farid was realizing that Zaki could possibly beat him. Looking into Farid’s eyes, Zaki suddenly understood what losing couldmean to his brother. Never would the villagers allow him to live it down. He would be laughed at by losing to a little child. Almost without thinking, Zaki kicked his feet and rose to the surface of the water a second before Farid’s head appeared beside him.The men around them cheered and patted Farid on the back. Farid, however, put his arm around Zaki’s shoulders. “Today,” Farid announced, “we shall have a new diver among us.” Then quietly, for Zaki’s ears alone, he said “Thank you, my brother.” And Zaki knew that they both had learned that it takes more than strength to makea man.12. What is the second paragraph mainly about?A. Zaki’s grandfather was a good diver.B. Zaki liked staying at home every day.C. Zaki practised hard in the water daily.D. Zaki’s grandfather encouraged him to dive.13. Which of the following best describes Zaki according to paragraph 3?A. Considerate.B. Ambitious.C. Confident.D. Adventurous.14. What can we infer from the last sentence of the text?A. Farid beat his little brother easily.B. Zaki was as strong as his brother.C. Zaki regretted losing the competition.D. Both Farid and Zaki had grown up.15. What is the best title for the text?A. Farid’s PrideB. Zaki’s ChallengeC. Brothers’ CompetitionD.

山西省2019_2020学年高一语文下学期期末考试试题含解析

【3题详解】
此题考查概括分析作者在文中的观点态度的能力。解答时,分析概括作者的观点态度,题型多种多样,有直接要求用自己的语言做分析概括的;有列出文中的一些语句要求做是非判断的;也有另列材料要求依据作者的观点作判断的;还有另列材料要求依据作者在文中的观点推断的。分析概括作者在文中的观点态度,一要注意着眼于全文,从整体上把握。作者直接表述的观点,可从字面上看出来;分散在文中各个局部的观点,就需要综合与概括;二要注意把握关键句子、显性内容,如各段的起始句、完毕句,文章的标题、论点或分论点、结论性句子等。
【点睛】做选择题,根本方法是排除法。但还要用好“比对法〞。就是把选项内容与原文有关内容认真、仔细地比拟、对照,不符合原文意思的,就是错误项,反之如此为正确项。那么,要比对哪些内容呢?比对词语,命题者在设置选项时对原句作了改装、重组,即主要采取了“删〞(删除原文的状语、定语、补语,改变原意)、“漏〞(只强调问题的一个方面,有意漏掉重要信息,断章取义)、“改〞(改换词语,曲解文意)、“凑〞(胡乱拼凑、东拉西扯、无中生有、随意组合信息)等方式设误。要看看选项在对原句改造过程中,删去了哪些词,改了哪些词,添了哪些词,它们是否与原文意思一致。一般而言,选项中的下面这些词语最值得我们优先比对:指代词(如“它〞“其〞等),比对它是否有偷换概念之嫌;X围词(如“都〞“所有〞“人人〞等),看它是否有任意扩大或缩小外延现象;程度词、时间词(如“或许〞“大概〞“必定〞“可能〞“似乎〞“已经〞“将来〞等),看它是否混淆偶然与必然、已然与未然,说法绝对等。比对关系,(句间、分句间的逻辑关系),看这种关系是否符合原文意思,是否合理。比对句间关系,如此要求考生不只是单纯地筛选信息,更应在筛选的根底上关注信息间的联系。

2019-2020学年大同市第二中学高三语文上学期期末试题及参考答案

2019-2020学年大同市第二中学高三语文上学期期末试题及参考答案一、现代文阅读(36分)(一)现代文阅读I(9分)阅读下面文字,完成下列小题。
材料一:【本报北京2月14日电(记者李韵)】日前,文化部在其官网首页发布《各地贯彻落实〈中华人民共和国非物质文化遗产法〉情况评估报告》。
报告显示,《中华人民共和国非物质文化遗产法》(以下简称《非遗法》)颁布五年来,各地落实情况喜忧参半。
2011年6月1日,《非遗法》正式实施。
为掌握法律实施五年来的落实情况,总结经验、发现问题、解决问题,文化部于2016年组织开展了《非遗法》贯彻落实情况检查,并委托中国非物质文化遗产保护中心对贯彻落实情况进行评估。
评估报告显示,截至2016年8月31日,全国有24个省(区、市)颁布了非遗的地方性法规共72部。
其中,17个省(区、市)的省级法规是在《非遗法》实施后制定的。
但是,从全国范围看,法律法规体系尚不完善,北京市、天津市、内蒙古自治区、吉林省、海南省、四川省、青海省7省(区、市)省级非物质文化遗产地方性法规尚未出台,立法工作亟待推进。
评估报告显示,2011年至2015年底,全国各省级财政累计投入163731万元,有10省(市)累计投入5000万元以上。
尽管五年来,各省财政投入逐年增加,但是依然不能满足实际工作的需要,各省普遍存在保护经费不足的问题。
截至2016年,文化部命名了四批共1986名国家级非遗项目代表性传承人,各省(区、市)批准公布了14928名省级非遗项目代表性传承人。
评估报告显示,非遗代表性传承人老龄化问题较为突出,在世的国家级代表性传承人中超过70周岁的已达50以上,开展传承人抢救性记录工作迫在眉睫。
有些传承人在抢救性记录过程中,就已经离开人世;一些传承人年事已高,无法完全展现技艺。
部分艺术院团改制后,面临着经营压力,有的传承人待遇因此受到影响,出现了无人肯学、后继乏人的状况。
(摘编自《光明日报》2017年2月15日第9版)材料二:“我们就是要把非遗文化传承作为工作、作为职业,通过现代工作室的打造和经营,希望能够找到一条非遗文化传承的职业化道路,避免因为入不敷出、生活难以为继而面临失传的窘境。

(阅读理解题)The poverty line(贫困线)is the minimum income that people need for an acceptable standard of living. People with incomes below the poverty line are considered poor. Economists study the causes of poverty in order to find solutions to the problem.As the general standard of living in the country rises, the poverty line does, too. Therefore, even with today's relatively high standard of living, about 10 percent of the people in the United States are below the poverty line. However, if these people had stable jobs, they could have an acceptable standard of living. Economists suggest several reasons why poor people do not have jobs.For one thing, more than half of the poor people in the United States are not qualified to work. Over 40 percent of the poor people are children. By law, children less than 16 years old cannot work in many industries. A large number of poor people are old. Many companies do not hire people over 65 years old, the normal retirement age.Some poor adults do not look for jobs for a variety of personal reasons: they are sick, they do not have any motivation(动力). They have family problems, or they do notbelieve that they can find a job.Other poor people look for a job but cannot find one. Many poor adults never went to high school. Therefore, when they look for jobs, they have few skills that they can offer.At the present time, the government thinks it can reduce poverty in the country in the following ways.First, if the national economy grows, businesses and industries hire more workers. Some of the poor who are qualified to look for jobs may find employment. Then they will no longer be below the poverty line.Second, if society invests in the poor, the poor will become more productive. If the government spends money on social programs, education, and training for poor people, the poor will have the skills to offer. Then it is more likely that they can find jobs.Finally, if the government distributes society's income differently, it raises some poor people above the poverty line. The government collects taxes from the non-poor and gives money to the poor. These payments to the poor are called welfare. In 1975 over 18 million people in the United States received welfare.Some economists are looking for better solutions to the poverty problem. However, at the present time, many people depend on welfare (福利)for a minimally acceptable standard of living.(1). (单选题) The author's main purpose to write this article is ________.(本题4.0分)A、to define what the poverty line isB、to explain why some people live below the poverty lineC、to find solutions to the problem of povertyD、 to show sympathy for those poor people(2). (单选题) Which of the following is NOT true?(本题4.0分)A、Ten percent of the Americans live a poor life.B、Poor people are those who live below the poverty line.C、The poverty line rises as the general standard of living rises.D、The poverty line tends to be at the same level.(3). (单选题) More than 40 percent of the poor people are children. This is mainly because ________(本题4.0分)A、they do not have enough motivationB、 they are so young that they are deprived of chances to workC、they fail to get enough educationD、 they are very poor in health(4). (单选题) Most of the American poor people are not qualified for employment because ______(本题4.0分)A、they to not have any motivation to workB、they are not very self-confidentC、they are too young or too old to workD、they have physical and family problems(5). (单选题) We may conclude from the passage that ________.(本题4.0分)A、better solutions to the poverty problem are not yet foundB、welfare will enable people to be richC、poor people are bound to go out of the poverty line if they have chances to do businessD、employment is the best solution to the poverty problem22. (阅读理解题)There is much more water than land on the surface of the earth. The seas and oceans cover nearly four-fifths of the whole world, and only one-fifth of it is land. If you traveled over the earth in different directions, you would have to spend much more of your time moving on water than moving on roads or railways. We sometimes forget that for every mile of land there are four miles of water.There is so much water on the surface of our earth that we have to use two words to describe it. We use the word SEAS to describe those parts of the water surface which are only a few hundred miles wide, and the word OCEANS to describe the huge areas of water which are thousands of miles wide and very deep.A sea such as the Mediterranean Sea provides an easy way of travelling from one country to another. Ships are frequently crossing the small seas of the world in all directions. Oceans separate the great continents. Until steamships were invented, a voyage across a wide ocean was a long and sometimes very dangerous journey. Oceans have only been used for travelling and trading within the last few hundred years. Even now, ships only use those parts of oceans which provide the shortest way across. The other parts of oceans are very seldom visited.You can understand that we do not know much about the oceans because of their huge size. Another reason why we know so little about them is because of their great depth. At the bottom of an ocean there is black darkness. Sunlight cannot reach the great depth.(1). (单选题) Travelling on water takes much more time than on roads or railways because the seas and oceans cover nearly_____ of the whole world.(本题4.0分)A、two-thirdsB、one-fourthC、 three-fifthsD、four-fifths(2). (单选题)Seas are those parts of the water surface which are____.(本题4.0分)A、only a few hundred miles wideB、 hundreds and hundreds of miles wideC、tens of hundreds of miles wideD、only a few hundred meters wide(3). (单选题) Because of invention of steamships a voyage across a wide ocean became____(本题4.0分)A、 a long and sometimes very dangerous journeyB、 a shorter and safer journeyC、 a long journeyD、 a very dangerous journey(4). (单选题) Oceans have only been used for travelling and trading____.(本题4.0分)A、very long agoB、in the past few hundred yearsC、for many hundreds of yearsD、 within the last few thousand years(5). (单选题) The reason why we know so little about the oceans is____.(本题4.0分)A、because of their huge sizeB、because of their great depthC、because of their huge size and great depthD、 because of the black darkness at the bottom of an ocean交卷返回。
