2020届新高考英语新题型练习完形填空阅读理解七选五套餐练(1)完形填空(山东省临沂市2020年高三上学期期末考试)Three years ago,I participated in Model United Nations(MUN)held by the Education Department,which was a mock(模拟的)UN activity.During the two days,students are separated in different groups which 21 different countries to debate and try to solve problems.MUN has 22 awards:best delegates(代表),honorary mentions,and verbal mentions.Each time I participate in MUN,I made good 23 and undoubtedly got a few awards.But I often felt as if I’d 24 because I had never won the best delegate award.I 25 those who didn’t deserve to win the award but won it various times,and I was just filled with 26 at their success.But later I realized that it was also 27 not to get the award because I could actually 28 something,and that I shouldn’t 29 the best delegate award until I was the best delegate I could be.Failures are completely subjective—we can look at a result as a failure or a 30.Any failure can be regarded as a(n) 31 because you can always learn something from it and do 32 next time.This is supported by John Locke’s theory that we are born with blank views:knowledge and ability are learned from our 33.That’s true.If I make a mistake in the life practice,then I probably won’t 34 that next time.I believe this is 35 the best way to become better.21.A.strengthen B.condemn C.inspire D.represent 22.A.identical B.temporary C.various D.false 23.A.preparations B.predictions C.appointments D.explanations 24.A.accelerated B.failed C.exited D.succeeded 25.A.approached B.trained C.expected D.witnessed26.A.relief B.envy C.satisfaction D.delight 27.A.annoyed B.ashamed C.good D.terrible 28.A.desert B.1earn C.delete D.display29.A.win B.miss C.deliver D.value30.A.bond B.bet C.victory D.1oss31.A.aim B.benefit C.burden D.1imit32.A.funnier B.worse C.better D.slower33.A.decisions B.attitudes C.positions D.experiences 34.A.repeat B.admit C.accept D.notice 35.A.wrongly B.scarcely C.truly D.narrowly阅读理解(山东师大附中2017级第三次月考)AI was in the garden with Augie, my grandson, watching the bees. “How do they make honey?” Augie asked. “Actually, Augie, I don’t know,” I replied. “But, Grandma, you have your phone,” he said. For Augie, holding a smartphone almost means knowing everything.During my childhood I was crazy about books. Over time, reading hijacked my brain, as large areas once processing the real world adapted to processing the printed word. As far as I can tell, this early immersion (沉浸) didn’t prevent my development.Many parents worry that “screen time” will damage children’s development, but recent research suggests that most of the common fears about children and screens are unfounded. There is one exception: looking at screens before bed really disturbs sleep, in people of all ages. The American Academy of Pediatrics (AAP) used to recommend strict restrictions on screen exposure. Last year, the organization examined the relevant science more thoroughly and changed its recommendations. The new guidelines stress that what matters is what children watch and with whom.New tools have always led to panic guesses. The novel, the telephone, and the television were all declared to be the End of Civilization, particularly in the hands of the young. Part of the reason may be that adult brains require a lot of focus and effort to learn something new, while children’s brains are designed to master new environments naturally. New technologies always seem disturbing to the adults attempting to master them, while attractive to those children likeAugie.When Augie’s father got home, Augie rushed to meet him and said in excitement. “Daddy, Daddy, look,” he said, reaching for my phone. “Do you know how bees make honey? I’ll show you…”21. Which of the following can best replace the underlined word “hijacked” in Paragraph 2?A. occupied.B. damaged.C. improved.D. relaxed.22. What do the new guidelines of AAP focus on about “screen time”?A. The harm to children.B. The content and context.C. Children’s sleep.D. People’s fears.23. What might be the author’s attitude towards “screen time”?A. Opposed.B. Doubtful.C. Disappointed.D. Favorable.BToday companies have branches around the world. More than 11% of the US employers and employees work online either full-time or part-time, and that number is continuing growing. It is believed that it is a waste of time and money to fly around the world for face-to-face meetings. An effective solution to this problem is to use Web meetings.A large group of presentations, training classes and meetings are done online without losing the face-to-face experience. Web meetings are online meetings where an organizer invites attendees to listen to or watch an online presentation by presenters. Besides, Web meetings can be recorded for later use in presentations or training projects or downloaded for on-demand playback.Presenters can take real-time surveys to study how to hold a successful meeting. Some Web meeting software programs can monitor the users’ desktop behavior to see if they become distracted from the presentation and begin working on other documents. If so, the program can tell presenters when the listeners lose their attention, and how long the distraction lasts. In this way, the presenters will know which parts of their meetings need improving.Web meetings can work well because they’re hosted on a server (服务器). Images from the presenter’s desktop are taken, uploaded to a server and then downloaded by people who have accessto the server. Web meetings require a powerful server to deal with several images a second and “serve” them back to thousands of users at the same time.Companies have two choices when it comes to these servers. They can either buy a special Web meeting server to host their meetings on-site, or they can pay for a Web meeting service every time and let the off-site provider worry about hosting the meetings. The choice depends on how frequently the company holds Web meetings, the average number of people attending the meetings, and the quality of engineering and information technology.Web meetings are an excellent example of how technology is changing the way we do business. With all the technologies today, the traditional office might soon be a thing of the past.24.What is the disadvantage of the traditional meeting?A.It needs more people to organize it.B.It is expensive and time-consuming.C.It results in traffic accidents frequently.D.It fails to meet the demands of big companies.25.How do some Web meeting software programs help improve the meetings?A.By presenting successful documents.B.By recording the frequency of distraction.C.By tracking the listeners’ state of attention.D.By taking surveys about a successful meeting.26.What do you know about Web meetings according to the text?A.Web meetings are likely to be widely used.B.Web meetings help presenters stay focused.C.Web meetings determine the quality of engineering.D.Web meetings work well without the help of a server.CEvery year, thousands of teenagers participate in programs at their local art museums. But do any of them remember their time at museum events later in life? A new report suggests that the answer is yes – and finds that alumni (毕业生) of arts-based museum programs credit them with changing the course of their lives, even years after the fact.The Whitney Museum of American Art, the Walker Art Center and the Museum of Contemporary Art, Los Angeles recently asked researchers to conduct a study to find out how effective their long-standing teen art programs really are. They involved over 300 former participants of four programs for teens that have been in existence since the 1990s. Alumni, whose current ages range from 18 to 36, were invited to find out how they viewed their participation years after the fact.Among the alumni surveyed, 75 percent of alumni rated the teen program experience as the most favorable impact on their own lives, beating family, school and their neighborhoods. Nearly 55 percent thought t hat it was one of the most important experiences they’d ever had, regardless of age. And two-thirds said that they were often in situations where their experience in museums affected their actions or thoughts.It turns out that participating in art programs also helps keep teens enthusiastic about arts even after they reach adulthood: 96 percent of participants had visited an art museum within the last two years, and 68 percent had visited an art museum five or more times within the last two years. Thirty-two percent of program alumni work in the arts as adults.Though the study is the first of its kind to explore the impact of teen-specific art programs in museums, it reflects other research on the important benefits of engaging with the arts. A decade of surveys by the National Endowment for the Arts found that childhood experience with the arts is significantly associated with their income and educational attainment as adults. Other studies have linked arts education to everything from lower drop-out rates to improvement in critical thinking skills.27. What does the underlined phrase “the fact” in Paragraph 1 refer to?A. Changing the course of children’s life.B. Participating in childhood art programs.C. Organizing arts-based museum programs.D. Remembering the time at museum events.28. What does Paragraph 2 mainly tell?A. The result of the study.B. The process of the study.C. The approach to the study.D. The object and content of the study.29. What can be inferred of the study mentioned in the text?A. Passion for arts may remain long in kids’ whole life.B. No other studies exist concerning the benefits of arts.C. Age matters in how people view their art experiences.D. Most children taking part in art programs will work in arts.30. Which of the following can be the best title for the text?A. How is Art Connected to Our Life?B. Can Art Education Affect Our Income?C. What Should Art Museums do for Kids?D. Should Children Walk into Art Museums?七选五(山东师范大学附属中学2020届高三第三次月考)Words have the power to build us up or tear us down. It doesn’t matter if the words come from ourselves or someone else. The positive and negative effects are just as lasting.31 We’re usually too embarrassed to admit it, though. In fact, we really shouldn’t be because more and more experts believe talking to ourselves out loud is a healthy habit. This “self-talk” helps us motivate ourselves, remember things, solve problems, and calm ourselves down. Be aware, though, that as much as 77% of self-talk tends to be negative. 32Often, words come out of our mouths without us thinking about the effect they will have. But we should be aware that our words cause certain responses in others. For example, when returning an item to a store, we might use warm, friendly language during the exchange. And the clerk will probably respond in a similar manner. 33Words possess power because of their lasting effect. Many of us regret something we oncesaid. We remember unkind words said to us as well. Before speaking, we should always ask ourselves: 34 If what we want to say doesn’t pass this test, then it’s better left unsaid.Words possess power: both positive and negative. Those around us receive encouragement when we speak positively. We can offer hope, build self-esteem and motivate others to do their best. 35 Will we use our words to hurt or to heal? The choice is ours.A.Is it loving?B.How should I say it?C.We all talk to ourselves sometimes.D.Negative words destroy all those things.E.Generally people like positive and pleasant words.F.However, critical language may cause anger and defense.G.So we should only speak encouraging words to ourselves.参考答案完型填空21-25DCABD 26-30 BCBAC 31-35 BCDAC阅读理解21-25ABD BC 26-30 ABDAD七选五CGFAD。

A few athletes were already stretching their arms, but most of us could barely focus. As I was burning off last night's wrong decision—a big meal, I spotted a poster about a gym's 21-day workout challenge, and I immediately signed up. I always wanted to train for a marathon, so I considered this as my warm-up. Besides, I needed to stop being lazy and this was my chance to make a change.It was easy to promise on paper, but three weeks of recommended exercise routines and diet restrictions wouldn't be easy. I stuck to working out 30 minutes a day, and I didn't disturb my normal routine. Instead, I had to be faced with the tough work of being more creative in my spare time, thus breaking some bad habits.Overcoming weaknesses with willpower was my goal for the next part of the journey. But the difficult part about making a challenge is realizing that “wanting" and “doing" are two very different things. Just like a career, you have to physically work for it rather than just wait for it to happen. But that's hard. Throughout the 21 days, I often told myself that the challenge was meaningless and tried to sabotage myself from exercising. However, finally I overcame that negative thought and kept working out.At the end of the challenge, I learned something even more important: Feeling the results is better than seeing them. I had fewer headaches and more energy, and was simply happier. I even felt a little smarter as I researched which foods were better for my body, and learned how to make healthier meals. I felt a sense of accomplishment, too, because even though I wanted to give up dozens of times, I didn't. I felt my waist got smaller and my arms got stronger, and I no longer felt guilty after having a piece of cake or a drink.24. What was the author's wrong decision?A. Going to the gym early.B. Training for a marathon.C. Eating a lot the previous night.D. Stopping being lazy for a change.25. What is paragraph 2 mainly about?A. Some of the author's bad habits.B. Some ways of the author's killing his spare time.C. The importance of sticking to the normal daily routine.D. The difficulty of the author's keeping on with the workout plan.26. What does the underlined word “sabotage" in paragraph 3 probably mean?A. Prevent.B. Hear.C. Improve.D. Distinguish.27. What did the author learn from the workout challenge?A. Eating healthy food is more important than exercising.B. Overcoming a challenge could bring good feelings to him.C. It's more important to see what he likes than just feel it.D. There was no need to feel guilty about things he disliked to do.CA new study shows that air pollution can cause a huge reduction in our intelligence. The study was a project involving researchers at Peking University in China and Yale University in the United States.The researchers reported that long-term exposure to air pollution can affect a person's mental abilities in two areas: Language and math.The researchers studied about 25,000 people from across China. Between 2010 and 2014, these Chinese men, women and children were given language and math tests. Then researchers compared the test results with measurements of pollution in the air, namely nitrogen dioxide and sulfur dioxide (二氧化硫).Xi Chen of the Yale School of Public Health led the study. He and his team found that breathing pollutedair can reduce a person's education level by about one year.Chen said that the effect generally is worse for those over 64 years of age, for men and for those with little or no education.“The older persons—they are more affected. And we find, quite amazingly, males are more affected than females. And people working outdoors are more affected than people working indoors.He noted that the youngest people in the study were 10 years old, while the oldest was 90 years old. They came from China's 33 provinces. In his words, the data and facts are convincing and this range of ages and locations across the country provided a real, objective and representative sample.The researchers noted that the effect of air pollution on verbal ability is even more serious as people age, especially among men and the less educated. The researchers also stressed that every country, whether developed, developing or poor, should focus on air pollution orhumans will face a bad situation.28. What is the result of the study?A. Air pollution has a bad effect on people's intelligence.B. Females are more affected by air pollution than males.C. Americans are more affected by air pollution than Chinese.D. People working indoors are actually not affected by air pollution.29. What did Chen say about the study?A. It is doubtful.B. It is extremely unfair.C. It is common and not representative.D. It is relatively objective and persuasive.30. What did the researchers emphasize in the last paragraph?A. The data from the 33 provinces is convincing.B. The whole world should pay attention to air pollution.C. The less educated take more responsibility for air pollution.D. Air pollution's influence on verbal ability is less serious as people age.31. Where is the text most likely taken from?A. A life diary.B. A guidebook.C. A science magazine.D. A biography.DStories are shared in many ways. They are described in books and magazines. They are read around the campfire at night. They are randomly distributed from stand-alone booths. But what else?To revive (复兴)literature in the era of fast news and smartphone addiction, Short Edition, a French publisher of short-form literature, has set up more than 30 story dispensers (分发机)in the USA in the past years to deliver fiction at the push of a button at restaurants, universities and government offices.Francis Ford Coppola, the film director and winemaker, liked the idea so much that he invested in the company and placed a dispenser at his Cafe Zoetrope in San Francisco. Last month public libraries in some other cities announced they would be setting them up, too. There is one on the campus at Penn State. A few can be found in downtown West Palm Beach, Fla. And Short Edition plans to announce more, including at the Los Angeles International Airport.“Everything old is n ew again," said Andrew Nurkin, the director of the Free Library of Philadelphia, which is one of the libraries that set up the dispensers. “We want people to be easily exposed to literature. We want to advance literacy among children and inspire theircreativity.Here's how a dispenser works: It has three buttons on top indicating choices for stories that can be read in one minute, three minutes or five minutes. When a button is pushed, a short story is printed. The stories are free. They are chosen from a computer category of more than 100,000 original submissions by writers whoseworks have been evaluated by Short Edition's judges, and transmitted over a mobile network. Offerings can be tailored to specific interests, like children's fiction or romance. Short Edition gets stories for its category by holding writing contests.Short Edition set up its first booth in 2016 and has 150 machines worldwide. “The idea is to make people happy," said Kristan Leroy, director of Short Edition, “There is too much unhappiness today. ”32. What do we know about the stories sent by dispensers?A. They are expensive.B. They are short in form.C. They can be read on smartphones.D. They are mainly taken from magazine literature.33. Where can you find the popularity of story dispensers in America?A. In paragraph 3.B. In paragraph 4.C. In paragraph 5.D. In paragraph 6.34. Which is the main purpose of setting up the dispensers according to Andrew Nurkin?A. To get rid of people's smartphone addiction.B. To reduce the financial stress of libraries.C. To make people have access to literature.D. To advertise the network literature.35. What is the best title for the text?A. Online Reading: a Virtual TourB. Short Edition, a French PublisherC. Everything Old Will Be Popular AgainD. Taste of Literature, at the Push of a Button七选五(福建省厦门外国语学校2020届高三12月月考)It is sometimes thought that the longing for material goods, the need to buy things, is a relatively modern invention. 36 Trade or shopping is certainly an ancient desire, and existed before our ancestors invented writing, laws, cities or farming, even before they used metal to make tools.Humans are born to trade. 37 Evidence from hunter-gatherers suggests that the exchange of food and other necessary things comes naturally, as well as the ability to keep a record of the credits involved. And once trade begins, the benefits are hard to resist.Ancient local coastal people in northern Australia traded fish hooks, along a chain of trading partners, with people living 400 miles inland, who cut and polished local stone to make axes(斧子). 38 Finally, both groups of "producers", by concentrating on things they could produce and exchanging them for other things they needed, benefited as a result.Trade in the necessities of life, such as food and simple tools, is not really surprising, considering the link between these basic items and survival. What is surprising, though, is that our taste for unnecessary expensive objects also goes back a long way.In South Africa, 100,000-year-old decorative dyes(染料)have been found in an area where none were produced. 39 Small round pieces of glass 76,000 years old were also found at the same place. The earliest jewellery known to us was not just random findings—they were grouped together in size and had holes like those used for threading onto a necklace.Archaeologists argue that trade prepared the way for the complex societies in which we live today. 40 However, their modern equivalents—fast cars and expensive clothes—hold the same attraction for us as "trade goods" did for people 100,000 years ago.A.And we don't need shops or money to do it.B.These are powerful proofs for cash purchase.C.In fact, its roots go back to the beginning of humanity.D.However, the first trade began from the exchange of objects.E.Modern-day shoppers may not be impressed by ancient glass pieces.F.It is thought that these goods were bought at least 30 kilometres away. G.Every individual along the chain made a profit, even if he produced neither himself.参考答案完形填空36-40 BABDA 41-45ADACD 46-50DBBCB 51-55DCBCD阅读理解21 -23 BDC 24 -27 CDAB 28 -31 ADBC 32-35 BACD七选五36-40 CAGFE。

材料一目前,被誉为“中国天眼”的500米口径球面射电望远镜,还未正式运行就新发现6颗脉冲星。

中国科学家在北京发布了它取得的首批成果。

“中国天眼”是中国“十一五”重大科技基础设施之一,基于选址方法、索网主动反射面、柔性索结合并联机器人的馈源支撑这三项中国自主创新技术,它突破了射电望远镜工程的极限。

在未来可预见的二三十年内,它将是我们这个星球最先进、最灵敏的射电望远镜。

人类迄今已发现2500余颗脉冲星。

但在“中国天眼”问世前,中国望远镜从未捕捉到新的脉冲星。

事实证明,重大的科学突破离不开科研仪器的进步。

世界各国相继认识到大科学装置在国家创新能力建设中的重要地位,中国也在不断兴建重器。

包括“中国天眼”在内,仅中国科学院目前运行和在建的重大科技基础设施就有23个。

2013年国务院印发的《国家重大科技基础设施建设中长期规划(2012-2030年)》对能源、生命、天文等7个科学领域进行了系统(甲)bùshǔ。

中国科学院国家天文台台长严俊认为,“中国天眼”调试进展超过预期、打破了大型同类设备调试周期的国际惯例,并有系统的科学产出,这得益于(乙)卓.有成效的早期科学规划和人才储备。

从最初不到5人的研究小组扩大到上百人团队,“中国天眼”凭借国内100多家参建单位的力量,由跟踪模仿发展到集成创新。

发布会当日,人们自发为“中国天眼”之父,项目总工程师兼首席科学家南仁东先生默哀。

2017年9月15日,在“中国天眼”落成近一周年之际,曾为之奔波奋斗的南先生(丙)溘.然长逝。

当年他毅然舍弃高薪,回国就任中国科学院北京天文台副台长。

1993年国际无线电科学联盟大会上,外国科学家们提出要建造新一代射电望远镜,以接受更多来自外太空的讯息。

南先生跟同事们说:“咱们也建一个吧!”从那时起,一干就是二十多年。

如今“中国天眼”新发现的脉冲星(丁)yìyì生辉,人们感慨它“足以告慰老南”。

海绵是结构很简单的动物,其静态的身体从来不超过几个细胞那么厚,即使如此,它们的周围也寄宿着活跃的微生物。有时候,通过显微镜都几乎看不到海绵的本体,因为它的上面覆满了微生物。北极熊漫步在北极的冰原之上,举目四周除了冰块别无其他,可实际上,它们身上仍紧紧簇拥着微生物。当尼尔·阿姆斯特朗和巴兹·奥尔德林登上月球时,他们踏出的一小步既是人类的一大步,也是微生物的一大步。奥逊·威尔斯曾经说过:“我们孤独地出生,孤独地活着,又孤独地死去。”这句话并不正确。纵使我们“孑然一身”,也绝对不孤独,我们与许多生命体共同生活在一起。一些动物在还是未受精的卵子时就被微生物占据并在其中繁衍,还有一些动物在出生的那一瞬间就有了伙伴。在我们的生命历程中,微生物从未缺席:我们吃东西时,它们也吃;我们旅行时,它们也结伴而行;我们死后,它们消化我们。对于我们每个人而言,人体都自成一个动物园。

此时,罗布·奈特正用棉签轻轻擦拭它的脸部边缘,奈特是一名研究微观生命的学者,他研究细菌和其他微生物,特别着迷存在于动物体内或体表的微生物。开展研究前,他首先得收集它们,收集蝴蝶的人会用网兜和罐子,奈特的工具则是棉签。他把棉签伸进巴巴的鼻孔,仅仅转上几秒钟,就足以让白色棉签头上沾满来自穿山甲体内的微生物。巴巴不仅是一只穿山甲,也是一个携带丰富微生物的聚合体:一些微生物生活在它的体内,绝大多数分布在肠道内,还有一些附着在它的脸部、肚子、爪子和鳞片表面。其实人类身上也寄宿着微生物,地球上的所有生物都一样——唯一的例外,是科学家在实验室无菌环境下极其小心地培育出来的极少数动物。我们身上仿佛在举办一场盛大的微生物展览,展品统称为微生物组。它们生活在我们的皮肤表面、身体内部,甚至是细胞内部。其中大部分是细菌,也有一些是其他的微小生命体,例如真菌(比如酵母菌)和古菌——后者的身份至今保持神秘,还有数量多到难以估量的病毒。

2020年普通高等学校招生全国统一考试(全国新高考Ⅰ卷)[答案]

2020年普通高等学校招生全国统一考试(全国新高考Ⅰ卷)答案速查 C D C BCBADACDBCABDAC一、选择题1.C 已知A ={x |1≤x ≤3},B ={x |2<x <4},在数轴上表示出两个集合,由图易知A ∪B ={x |1≤x <4}.故选C .2.D2-i1+2i =(2-i )(1-2i )(1+2i )(1-2i )=-5i5=-i .故选D . 3.C 第一步:安排甲场馆的志愿者,则甲场馆的安排方法有C 61=6种,第二步:安排乙场馆的志愿者,则乙场馆的安排方法有C 52=10种,第三步:安排丙场馆的志愿者,则丙场馆的安排方法有C 33=1种.所以共有6×10×1=60种不同的安排方法.故选C .4.B 由题意作出如图所示的截面图,设所求角为α,由图易知α=40°.故选B .5.C 用Venn 图表示学生参加体育锻炼的情况,A +B 表示喜欢游泳的学生数占该校学生总数的比例,B +C 表示喜欢足球的学生数占该校学生总数的比例,A +B +C 表示喜欢足球或游泳的学生数占该校学生总数的比例,即A +B =82%,B +C =60%,A +B +C =96%,B 表示既喜欢足球又喜欢游泳的学生数占该校学生总数的比例,故B =82%+60%-96%=46%.故选C .6.B 因为R 0=3.28,T =6且R 0=1+rT ,所以指数增长率r =R 0-1T=0.38,设累计感染病例增加1倍需要的时间为t 天,则I (t )=2I (0),即e rt =2,即e 0.38t =2,两边取自然对数得ln e 0.38t =ln 2,即0.38t =ln 2,又ln 2≈0.69,所以t =ln20.38≈0.690.38≈1.8.故选B . 7.A 解法一:如图,过点P 作PP 1⊥直线AB 于P 1,过点C 作CC 1⊥直线AB 于C 1,过点F 作FF 1⊥直线AB 于F 1,AP ⃗⃗⃗⃗⃗ ·AB ⃗⃗⃗⃗⃗ =|AP ⃗⃗⃗⃗⃗ |·|AB ⃗⃗⃗⃗⃗ |·cos ∠PAB ,当∠PAB 为锐角时,|AP ⃗⃗⃗⃗⃗ |·cos ∠PAB =|AP 1⃗⃗⃗⃗⃗⃗⃗ |,当∠PAB 为钝角时,|AP ⃗⃗⃗⃗⃗ |·cos ∠PAB =-|AP 1⃗⃗⃗⃗⃗⃗⃗ |,所以当点P 与C 重合时,AP ⃗⃗⃗⃗⃗ ·AB ⃗⃗⃗⃗⃗ 最大,此时AP ⃗⃗⃗⃗⃗ ·AB ⃗⃗⃗⃗⃗ =|AC 1⃗⃗⃗⃗⃗⃗⃗ ||AB ⃗⃗⃗⃗⃗ |=6,当点P 与F 重合时,AP ⃗⃗⃗⃗⃗ ·AB ⃗⃗⃗⃗⃗ 最小,此时AP ⃗⃗⃗⃗⃗ ·AB ⃗⃗⃗⃗⃗ =-|AF 1⃗⃗⃗⃗⃗⃗⃗ ||AB ⃗⃗⃗⃗⃗ |=-2,又因为点P 是正六边形ABCDEF 内的一点,所以-2<AP ⃗⃗⃗⃗⃗ ·AB ⃗⃗⃗⃗⃗ <6.故选A .解法二:连接AE ,以A 为坐标原点,AB 所在直线为x 轴,AE 所在直线为y 轴,建立平面直角坐标系(图略),则A (0,0),B (2,0),设P (x 0,y 0),则-1<x 0<3.AB ⃗⃗⃗⃗⃗ =(2,0),AP ⃗⃗⃗⃗⃗ =(x 0,y 0),则AB ⃗⃗⃗⃗⃗ ·AP⃗⃗⃗⃗⃗ =2x 0∈(-2,6),故选A . 解后反思 解决以平面多边形为载体,有关平面向量数量积的复杂计算问题时,可以建立恰当的坐标系,将复杂的运算转化为简单的坐标运算,会大大降低难度. 8.D ∵f (x )是定义在R 上的奇函数,∴f (x -1)的图象关于点(1,0)中心对称,又∵f (x )在(-∞,0)上单调递减,∴f (x -1)在(-∞,1)上单调递减,在(1,+∞)上也单调递减,且过(-1,0)和(3,0),f (x -1)的大致图象如图:当-1≤x ≤0时,f (x -1)≤0,∴xf (x -1)≥0;当1≤x ≤3时,f (x -1)≥0,∴xf (x -1)≥0.综上,满足xf (x -1)≥0的x 的取值范围是[-1,0]∪[1,3].故选D . 二、选择题9.ACD A 选项中,若m >n >0,则方程mx 2+ny 2=1可变形为x 21m+y 21n=1,因为m >n >0,所以0<1m <1n ,所以此曲线表示椭圆,且焦点在y 轴上,所以A 正确.B 选项中,若m =n >0,则方程mx 2+ny 2=1可变形为x 2+y 2=1n ,所以此曲线表示圆,半径为√n ,所以B 不正确.C 选项中,若mn <0,则此曲线应为双曲线,mx 2+ny 2=0可化为y 2=-mx 2n,即y =±√-mnx ,即双曲线的渐近线方程为y =±√-mn x ,所以C 正确.D 选项中,若m =0,n >0,则方程mx 2+ny 2=1可化为y 2=1n(x ∈R),即y =±√n,表示两条直线,所以D 正确. 故选ACD .10.BC 由题图可知,T 2=2π3-π6=π2,∴T =π,由T =2π|ω|可知,2π|ω|=π,∴|ω|=2,不妨取ω=2,则f (x )=sin(2x +φ),又∵图象过(π6,0),∴sin (π3+φ)=0,又∵π6是f (x )的下降零点,∴π3+φ=π+2k π,k ∈Z,∴φ=2π3+2k π,k ∈Z,不妨取φ=2π3,则f (x )=sin (2x +2π3)=sin [(2x +π6)+π2]=cos (2x +π6),f (x )=sin (2x +2π3)=sin [π-(π3-2x)]=sin (π3-2x),故选BC . 11.ABD ∵a >0,b >0,a +b =1,∴0<a <1,0<b <1,b =1-a.ab ≤(a+b 2)2=14.对于A 选项,a 2+b 2=a 2+(1-a )2=2a 2-2a +1=2(a -12)2+12≥12,当且仅当a =b =12时,取等号,A 正确;对于B 选项,a -b =a -(1-a )=2a -1,∵0<a <1,∴-1<2a -1<1,∴12<22a -1<2,∴2a -b >12成立,B 正确;对于C 选项,∵0<ab ≤14,a >0,b >0,∴log 2a +log 2b =log 2(ab )≤log 214=-2,C 不正确;对于D 选项,∵(√a +√b )2=a +b +2√ab =1+2√ab ≤1+a +b =2,∴√a +√b ≤√2成立,D 正确.12.AC 对于A,若n =1,则p 1=1,∴H (X )=-1×log 21=0,A 正确. 对于B,若n =2,则p 1+p 2=1,∴H (X )=-∑i=12p i log 2p i =-(p 1log 2p 1+p 2log 2p 2),∵p 1+p 2=1,∴p 2=1-p 1,p 1∈(0,1), ∴H (X )=-[p 1log 2p 1+(1-p 1)log 2(1-p 1)], 令f (p 1)=-[p 1log 2p 1+(1-p 1)log 2(1-p 1)], ∴f '(p 1)=-p 1·1p1·ln2+log 2p 1+(1-p 1)·-1(1-p 1)·ln2-log 2(1-p 1)=-[log 2p 1-log 2(1-p 1)]=log 21-p 1p 1,令f '(p 1)>0,得0<p 1<12;令f '(p 1)<0,得12<p 1<1. ∴y =f (p 1)在(0,12)上为增函数,在(12,1)上为减函数, ∴H (X )随着p 1的增大先增大后减小,B 不正确.对于C,由p i =1n(i =1,2,…,n )可知,H (X )=-∑i=1np i log 2p i =-∑i=1n 1nlog 21n=log 2n ,∴H (X )随着n 的增大而增大,C 正确.对于D,解法一(特例法):不妨设m =1,n =2,则H (X )=-∑i=12p i log 2p i =-(p 1log 2p 1+p 2log 2p 2),由于p 1+p 2=1,不妨设p 1=p 2=12,则H (X )=-(12log 212+12log 212)=log 22=1,H (Y )=-1×log 21=0,故H (X )>H (Y ),D 不正确. 解法二:由P (Y =j )=p j +p 2m +1-j (j =1,2,…,m ),得P (Y =1)=p 1+p 2m ,P (Y =2)=p 2+p 2m -1,……,P (Y =m )=p m +p m +1, ∴H (Y )=-∑j=1m[(p 1+p 2m )log 2(p 1+p 2m )+(p 2+p 2m -1)log 2(p 2+p 2m -1)+…+(p m +p m +1)log 2(p m +p m +1)],由n =2m ,得H (X )=-∑i=12mp i log 2p i =-(p 1log 2p 1+p 2log 2p 2+…+p 2m log 2p 2m ),不妨设0<a <1,0<b <1,且0<a +b ≤1,则log 2a <log 2(a +b ),a log 2a <a log 2(a +b ),同理b log 2b <b log 2(a +b ),∴a log 2a +b log 2b <(a +b )log 2(a +b ), ∴p 1log 2p 1+p 2m log 2p 2m <(p 1+p 2m )log 2(p 1+p 2m ),p 2log 2p 2+p 2m -1log 2p 2m -1<(p 2+p 2m -1)log 2(p 2+p 2m -1), ……p m log 2p m +p m +1log 2p m +1<(p m +p m +1)log 2(p m +p m +1), ∴∑i=12mp i log 2p i <∑j=1m(p j +p 2m +1-j )log 2(p j +p 2m +1-j ),∴H (X )>H (Y ),D 不正确. 三、填空题 13.答案163解析 解法一:在抛物线y 2=4x 中,2p =4,斜率为√3的直线倾斜角θ=π3, ∴过焦点的弦长|AB |=2psin 2θ=4sin 2π3=434=163.解法二:设A (x 1,y 1),B (x 2,y 2),由已知可得抛物线y 2=4x 的焦点为F (1,0),过点F 且斜率k =√3的直线方程为y =√3(x -1),联立{y 2=4x ,y =√3(x -1),消去y 得3x 2-10x +3=0, ∴{x 1+x 2=103,x 1x 2=1,∴|AB |=√1+k 2√(x 1+x 2)2-4x 1x 2=√1+3×√1009-4=163.14.答案 3n 2-2n解析 ∵数列{2n -1}的项为1,3,5,7,9,11,13,…, 数列{3n -2}的项为1,4,7,10,13,…, ∴数列{a n }是首项为1,公差为6的等差数列, ∴a n =1+(n -1)×6=6n -5, ∴数列{a n }的前n 项和S n =(1+6n -5)×n2=3n 2-2n.15.答案 4+5π2解析 如图,连接OA ,过点A 分别作AQ ⊥DE ,AK ⊥EF ,垂足为Q ,K ,设AK 与BH ,DG 分别交于点M ,N ,作OP ⊥DG 于点P ,则AQ =AK =7 cm,∴DN =7 cm,∵DG =EF =12 cm,∴NG =5 cm,∵NK =DE =2 cm,∴AN =5 cm,∴△ANG 为等腰直角三角形,∴∠GAN =45°,∵∠OAG =90°,∴∠OAM =45°,设AM =OM =x cm,则PN =x cm,∴DP =(7-x )cm,∵tan∠ODG =35,∴OP =[(7-x )×35]cm,∵AM +MN +NK =7 cm,即x +(7-x )×35+2=7,解得x =2,∴OA =2√2 cm,∴S 阴影=π×(2√2)2×38+(2√2)2×12-π×122=3π+4-π2=(4+5π2)cm 2.16.答案√2π2解析 易知四边形A 1B 1C 1D 1为菱形,∠B 1A 1D 1=60°,连接B 1D 1,则△B 1C 1D 1为正三角形,取B 1C 1的中点O ,连接D 1O ,易得D 1O ⊥B 1C 1, ∴D 1O ⊥平面BCC 1B 1,取BB 1的中点E ,CC 1的中点F ,连接D 1E ,D 1F ,OE ,OF ,EF ,易知D 1E =D 1F =√5, 易知以D 1为球心,√5为半径的球面与侧面BCC 1B 1的交线为以O 为圆心,OE 为半径的EF⏜, ∵B 1E =B 1O =1,∴OE =√2, 同理OF =√2,易知EF =2, ∴∠EOF =90°,∴EF⏜的长=14×(2π×√2)=√2π2.解题关键 利用题设条件证明D 1O ⊥平面BCC 1B 1,从而说明球面与侧面BCC 1B 1的交线是以O 为圆心,OE 为半径的EF ⏜是解题的关键.四、解答题17.解析方案一:选条件①.由C=π6和余弦定理得a2+b2-c22ab=√32.由sin A=√3sin B及正弦定理得a=√3b.于是2222√3b2=√32,由此可得b=c.由①ac=√3,解得a=√3,b=c=1.因此,选条件①时问题中的三角形存在,此时c=1.方案二:选条件②.由C=π6和余弦定理得a2+b2-c22ab=√32.由sin A=√3sin B及正弦定理得a=√3b.于是2222√3b2=√32,由此可得b=c,B=C=π6,A=2π3.由②c sin A=3,所以c=b=2√3,a=6.因此,选条件②时问题中的三角形存在,此时c=2√3.方案三:选条件③.由C=π6和余弦定理得a2+b2-c22ab=√32.由sin A=√3sin B及正弦定理得a=√3b.于是2222√3b2=√32,由此可得b=c.由③c=√3b,与b=c矛盾.因此,选条件③时问题中的三角形不存在.18.解析(1)设{a n}的公比为q.由题设得a1q+a1q3=20,a1q2=8.解得q1=12(舍去),q2=2.由题设得a1=2.所以{a n}的通项公式为a n=2n.(2)由题设及(1)知b1=0,且当2n≤m<2n+1时,b m=n.所以S100=b1+(b2+b3)+(b4+b5+b6+b7)+…+(b32+b33+…+b63)+(b64+b65+…+b100) =0+1×2+2×22+3×23+4×24+5×25+6×(100-63)=480.思路分析 (1)设出公比q ,由题设条件求得a 1和q ,利用等比数列的通项公式得出结果.(2)由题设及(1)推导出b m ,再计算数列{b m }的前100项和,即先给m 赋值,推导出规律,再进行运算,得到S 100的值.19.解析 (1)根据抽查数据,该市100天的空气中PM2.5浓度不超过75,且SO 2浓度不超过150的天数为32+18+6+8=64,因此,该市一天空气中PM2.5浓度不超过75,且SO 2浓度不超过150的概率的估计值为64100=0.64. (2)根据抽查数据,可得2×2列联表:SO 2PM2.5 [0,150](150,475][0,75] 64 16 (75,115]1010(3)根据(2)的列联表得K 2=100×(64×10-16×10)280×20×74×26≈7.484.由于7.484>6.635,故有99%的把握认为该市一天空气中PM2.5浓度与SO 2浓度有关.20.解析 (1)因为PD ⊥底面ABCD ,所以PD ⊥AD.又底面ABCD 为正方形,所以AD ⊥DC.因此AD ⊥平面PDC.因为AD ∥BC ,AD ⊄平面PBC ,所以AD ∥平面PBC. 由已知得l ∥AD. 因此l ⊥平面PDC.(2)以D 为坐标原点,DA ⃗⃗⃗⃗⃗ 的方向为x 轴正方向,建立如图所示的空间直角坐标系D -xyz.则D (0,0,0),C (0,1,0),B (1,1,0),P (0,0,1),DC ⃗⃗⃗⃗⃗ =(0,1,0),PB ⃗⃗⃗⃗⃗ =(1,1,-1). 由(1)可设Q (a ,0,1),则DQ ⃗⃗⃗⃗⃗⃗ =(a ,0,1). 设n =(x ,y ,z )是平面QCD 的法向量,则{n ·DQ ⃗⃗⃗⃗⃗⃗ =0,n ·DC ⃗⃗⃗⃗⃗ =0,即{ax +z =0,y =0.可取n =(-1,0,a ). 所以cos<n ,PB ⃗⃗⃗⃗⃗ >=n ·PB⃗⃗⃗⃗⃗ |n |·|PB ⃗⃗⃗⃗⃗ |=√3√1+a 2.设PB 与平面QCD 所成角为θ,则sin θ=√33×√1+a 2=√33√1+2aa 2+1.因为√33√1+2aa 2+1≤√63,当且仅当a =1时等号成立,所以PB 与平面QCD 所成角的正弦值的最大值为√63.解后反思 (1)证明线面垂直最常用的方法是线面垂直的判定定理,而本题中直线l 不易作出,直接证明比较困难,通过线面平行的性质定理可以判定直线l ∥AD ,从而将问题转化为证明AD ⊥平面PDC ,问题得证.(2)建立空间直角坐标系,利用向量法求解.先用变量表示出PB 与平面QCD 所成角的正弦值,再转化为函数最值问题,此类问题要注意变量的取值范围,避免最终结果出错.21.解析 f (x )的定义域为(0,+∞),f '(x )=a e x -1-1x .(1)当a =e 时,f (x )=e x -ln x +1,f '(1)=e-1,曲线y =f (x )在点(1,f (1))处的切线方程为y -(e+1)=(e-1)(x -1),即y =(e-1)x +2. 直线y =(e-1)x +2在x 轴,y 轴上的截距分别为-2e -1,2. 因此所求三角形的面积为2e -1. (2)当0<a <1时,f (1)=a +ln a <1.当a =1时,f (x )=e x -1-ln x ,f '(x )=e x -1-1x .当x ∈(0,1)时,f '(x )<0;当x ∈(1,+∞)时,f '(x )>0.所以当x =1时,f (x )取得最小值,最小值为f (1)=1,从而f (x )≥1. 当a >1时,f (x )=a e x -1-ln x +ln a ≥e x -1-ln x ≥1. 综上,a 的取值范围是[1,+∞).名师点评 本题第(2)问中,由不等式成立求参数的取值范围,常规解法是分离参数转化为求函数的最值问题,而本题中参数分布范围较广,无法分离,所以要对参数进行分类讨论,怎样分类是本题的一个难点,特别是当a >1时,证明f (x )≥1需要用到a =1时的结论,思路很窄,技巧性较强. 22.解析 (1)由题设得4a 2+1b 2=1,a 2-b 2a 2=12,解得a 2=6,b 2=3. 所以C 的方程为x 26+y 23=1. (2)设M (x 1,y 1),N (x 2,y 2).若直线MN 与x 轴不垂直,设直线MN 的方程为y =kx +m ,代入x 26+y 23=1得(1+2k 2)x 2+4kmx +2m 2-6=0. 于是x 1+x 2=-4km1+2k 2,x 1x 2=2m 2-61+2k 2.①由AM ⊥AN 知AM⃗⃗⃗⃗⃗⃗ ·AN ⃗⃗⃗⃗⃗⃗ =0,故(x 1-2)(x 2-2)+(y 1-1)(y 2-1)=0,可得(k 2+1)x 1x 2+(km -k -2)(x 1+x 2)+(m -1)2+4=0.将①代入上式可得(k 2+1)2m 2-61+2k 2-(km -k -2)4km1+2k 2+(m -1)2+4=0. 整理得(2k +3m +1)(2k +m -1)=0.因为A (2,1)不在直线MN 上,所以2k +m -1≠0, 故2k +3m +1=0,k ≠1.于是MN 的方程为y =k (x -23)-13(k ≠1). 所以直线MN 过点P (23,-13).若直线MN 与x 轴垂直,可得N (x 1,-y 1). 由AM ⃗⃗⃗⃗⃗⃗ ·AN⃗⃗⃗⃗⃗⃗ =0得(x 1-2)(x 1-2)+(y 1-1)(-y 1-1)=0. 又x 126+y 123=1,可得3x 12-8x 1+4=0.解得x 1=2(舍去)或x 1=23. 此时直线MN 过点P (23,-13). 令Q 为AP 的中点,即Q (43,13).若D 与P 不重合,则由题设知AP 是Rt △ADP 的斜边,故|DQ |=12|AP |=2√23. 若D 与P 重合,则|DQ |=12|AP |.综上,存在点Q (43,13),使得|DQ |为定值.。

备战2020年山东新高考新题型专练(作图题)(解析版)热力环流与天气系统1.某学生利用自己制作的学具,模拟演示“热力环流”过程。

实验开始前,学生观察到木盒中间悬挂的锡纸条没有明显的摆动,如图甲所示。

实验开始后,学生点燃蜡烛,并在、纸杯中放入冰块,逐渐观察到两张锡纸条有明显的摆动,如图乙所示。

多次重复实验,学生发现结果相同。

读图回答下列问题。

根据实验过程绘制与乙一致的热力环流示意图,并标出近地面气压的高低状况。

(4分)1.【答案】如图2.阅读图文资料,完成下列要求。

绿洲指在大尺度荒漠背景基质上,以小尺度范围,但具有相当规模的生物群落为基础,构成能够相对稳定维持的、具有明显小气候效应的异质生态景观。

由于绿洲与荒漠的下垫面性质不同,在两者之间存在热力环流。

下图为我国西北局部区域图,图示区域荒漠广布,森林、草原分布极少,除绿洲外,主要分布在山地。

请在下图线段上用箭头表示出夏季夜间的热力环流,在方框中填注近地面的气压状况,并说明近地面气流的(湿度和温度)性质。

(5分)2.【答案】画出气流方向(2分)标注出气压(1分)湿度低;温度低(2分)3.阅读图文资料,完成下列要求。

山谷风是在天气晴朗的山地区域,风向昼夜间发生反向转变的风。

下图示意某时段山谷等压面分布。

根据热力环流原理用箭头绘出气流的运动方向,并分析判断的依据。

3.【答案】中间两组箭头向上,两侧箭头向下。

依据山谷等压面分布图可知,图示山谷与山坡同一水平面相比,山谷处等压线向下弯曲,说明山谷处气压低,气温高,山坡处气压高,气温低,可以判断为夜晚,夜晚吹山风。

【知识拓展】在等压面图上判断气压高低的方法:垂直方向上:随着高度增加气压降低。

水平方向上:同一水平面上,等压面上凸处气压高,下凹处气压低。

4.下图为鲁尔工业园区和沪宁杭工业区的局部区域图,左上方为鲁尔工业园区A地月平均气温曲线和降水量柱状图。

组合11 现代诗歌阅读+文言文+作文板块一现代诗歌(本题共4小题,16分)阅读下面的诗歌,完成6~9题老马臧克家总得叫大车装个够,它横竖不说一句话,背上的压力往由里扣,它把头沉重地垂下!这刻不知道下刻的命,它有泪只往心里咽,眼里飘来一道鞭影,它抬起头望望前面.——作于1932年6.下列对本诗相关内容的理解,不正确的一项是(3 分)A.“背上的压力往肉里扣”, 一“扣”字,描绘出老马精疲力竭、奋力挣扎的形象,展现了老马肉体和精神的重压,形神毕现。

B.“它有泪只往心里咽”, “咽”字将老马人格化表现痛苦之深,压力之大,使之更为深刻的表现无法摆脱的痛苦的困境。

C. “它横竖不说一句话”是劳动人民的写照,表现劳动人民表面忍受痛苦,默默承受,内心却有强烈的反抗想法。

D. “眼里飘来一道鞭影”,“飘”字看似很轻,实际上是很重的欺压,有“扬起来很很抽下”的意思。

6.C 解析:没有表现反抗心理,是一种无可奈何。

老马不甘心受欺凌却又无力反抗,只能继续在悲惨的生活中挣扎,无奈而又悲凉,激起人们对老马不幸的同情和对不公平命运的义愤。

7.下列对本诗艺术特色的分析鉴赏,不正确的一项是(3分)A、老马象征着贫苦的农民,作者通过写老马,实际上写出了三十年代农民的悲惨命运。

B、全诗充满了哀怨的气氛和凄楚的情调,饱含了作者对农民的同情,对统治者的愤恨。

C、作者以悲愤的笔触,表达发对劳动人民“哀其不幸,怒其不争”的感情。

D、诗人善于在现实生活中捕捉典型镜头,逼真地刻画出老马的形象,朴素中见坚实,平淡中见深远。

7.C 解析:诗人曾说过:“我曾写下《烙印》,《生活》,《希望》和《老马》表现我的人生观和生活态度”。

《老马》就是对这样的生活态度的注释:当前的磨难就是你的对手,运尽气力去和它苦斗。

臧克家的特点就是他不同于新月派、现代派诗人以及中国诗歌会诗人的“坚忍主义”。

他能严肃地面对现实生活中的险恶苦难,“从棘针尖上去认识人生”;他能带着倔强的精神沉着而有锋棱地去迎接磨难。

组合05 现代诗歌+文言文+作文板块一现代文阅读(本题共5小题,19分)(二)现代文阅读II(本题共4小题,16分)阅读下面的文字,完成6~9题。

壮士心臧克家江庵的夜和着青灯残了,壮士的梦正灿烂地开花,枕着一卷兵书,一支剑,灯光开出了一头白发。

突然睁大眼睛,战鼓在催他,(深夜里木鱼一声又一声)跨出门来,星斗恰似当年,铁衣上响着塞北的朔风。

前面分明是万马奔腾,他举起剑来嘶喊了一声,从此不见壮士归来,门前的江潮夜夜澎湃。

(注)这首诗作于1934年1月11日,正值抗日战争爆发前夕,社会正处于日军践踏华北,窥视中原的危急关头。

6.下列对本诗相关内容的理解,不正确的一项是(3分)A.这首诗写一位壮士寄寓于江边的一个寺庵,从淹留中奋起,决然上马杀敌的故事,壮士就是爱国志士的缩影。

B.“枕着一卷兵书,一支剑”,主要突出壮士的孤独;“灯光开出了一头白发”,说尽岁月的蹉跎和英雄迟暮的感慨。

C.“星斗恰似当年”一句,涵盖了很大的时间跨度,包容了丰富的故事,可以想见壮士当年的英勇无畏与艰辛。

D.壮士从梦境中冲向战场,义无反顾,执着地为理想信念而战,充满了英雄壮气,也暗喻了诗人的渴盼之情。

6.B【解析】本题综合考查鉴赏诗歌形象,语言和表达技巧的能力。

采用了客观选择题的形式。

解答此类题目,首先要审题,即明确题干的要求,然后要注意了解诗歌的创作背景,参看注释,逐句翻译诗句,接着把握诗歌的意象,分析诗歌营造了什么样的意境,领悟作者表达了怎么样的思想情感,思考诗歌中运用了哪些表现手法,再对照选项一一确认,得出答案。

本题中,B项,“主要突出壮士的孤独”错误,“枕着一卷兵书,一支剑”,表现壮士的身份。

所以选B项。

7.下列对本诗艺术特色的分析鉴赏,不正确的一项是(3分)A.“江庵的夜和着青灯残了”,既交代地点又说明时间。

“和”在这里是动词,简洁如画的一句诗渲染了一种寂寥的氛围。

B.“壮士的梦正灿烂地开花”,梦能开花,诗人想象奇特瑰丽,慧心独具,一点不落俗套,字里行间,沸腾着诗情。

2020新高考题型详解-语文、数学、英语模拟试卷

2020新高考题型详解-语文、数学、英语模拟试卷

2020新高考题型详解-语文、数学、英语模拟试卷2020年普通高等学校招生全国统一考试模拟卷数学从试卷的结构和内容看,数学总体题量没有太大变化,但是考试的方法有些变化,题目也比较新颖,从考试中心了解到,今年的数学考试会越来越灵活,2019年高考算人的身高,就是把数学考活用,今年高考更加会把高考知识点活用起来,比如用在建设方面,高考建设,计算成本,用打洞还是高架,还是避开等让学生去算。

这样下来数学只会刷题已经不能拿到高分,要懂得知识点的活用,考试中心命题老师提示,考生要把高考的知识点梳理清楚,要知道什么是难点,什么是易错点,什么是失分点等,只要把知识点梳理清楚那么这是也就很容易知道了,知识点也会活用了。

知识点梳理最典型的就是衡水中学他们的学生都会进行知识点梳理,梳理好了再刷题,所以他们的学生错过的知识点不会考错第二次,他们有自己内部的知识点梳理资料,名字叫名校周考试题汇编,大家快去去找找,拿来用,如果找不到也可以找到类似的,搜高考必刷知识点就行。

2020年普通高等学校招生全国统一考试模拟卷语文通览语文试卷,有一下几个特点:①作文仍然是任务驱动型,侧重交际应用(发言稿)和具体情境写作。

2020年备考,有必要在常见应用文体,比如发言稿、辩论稿、演讲稿、书信等上加大力度。

②兼考现代新诗鉴赏和古代诗歌鉴赏,前者分值为令人咋舌的16分,作为现代文板块考查,后者保持2019年的9分(2000年高考全国卷曾考查过郑敏诗歌《金黄的稻束》)。

考生纷纷表示,此前老师们复习以小说为主,突然考现代新诗,有些猝不及防。

③区分度或继续缩小。

这是一个隐隐的担忧,选择题减少,对阅卷提出更高要求,而区分度是否会有所缩小?但愿不会!这一次模拟考试,对后期学生复习备考具有一定的风向标作用。

命题思路、考查形式、试题结构、出题重点,或由此大致确定。

④文言文出现主观题,保留了断句、文化常识、文意理解(选择题)等传统题型,分值20分(近年全国卷一般为19分),翻译减少2分,整体相对于之前的三个选择题加2小题翻译题,强化信息筛选概括,难度明显加大。

组合12 现代文诗歌+文言文+作文(解析版)-2020年新高考山东语文新题型组合训练

组合12 现代诗歌阅读+文言文+作文板块一现代诗歌(本题共4小题,16分)阅读下面的诗歌,完成6~9题老马臧克家总得叫大车装个够,它横竖不说一句话,背上的压力往由里扣,它把头沉重地垂下!这刻不知道下刻的命,它有泪只往心里咽,眼里飘来一道鞭影,它抬起头望望前面.——作于1932年6.下列对本诗相关内容的理解,不正确的一项是(3 分)A.“背上的压力往肉里扣”, 一“扣”字,描绘出老马精疲力竭、奋力挣扎的形象,展现了老马肉体和精神的重压,形神毕现。

B.“它有泪只往心里咽”, “咽”字将老马人格化表现痛苦之深,压力之大,使之更为深刻的表现无法摆脱的痛苦的困境。

C. “它横竖不说一句话”是劳动人民的写照,表现劳动人民表面忍受痛苦,默默承受,内心却有强烈的反抗想法。

D. “眼里飘来一道鞭影”,“飘”字看似很轻,实际上是很重的欺压,有“扬起来很很抽下”的意思。

6.C 解析:没有表现反抗心理,是一种无可奈何。

老马不甘心受欺凌却又无力反抗,只能继续在悲惨的生活中挣扎,无奈而又悲凉,激起人们对老马不幸的同情和对不公平命运的义愤。

7.下列对本诗艺术特色的分析鉴赏,不正确的一项是(3分)A、老马象征着贫苦的农民,作者通过写老马,实际上写出了三十年代农民的悲惨命运。

B、全诗充满了哀怨的气氛和凄楚的情调,饱含了作者对农民的同情,对统治者的愤恨。

C、作者以悲愤的笔触,表达发对劳动人民“哀其不幸,怒其不争”的感情。

D、诗人善于在现实生活中捕捉典型镜头,逼真地刻画出老马的形象,朴素中见坚实,平淡中见深远。

7.C 解析:诗人曾说过:“我曾写下《烙印》,《生活》,《希望》和《老马》表现我的人生观和生活态度”。

《老马》就是对这样的生活态度的注释:当前的磨难就是你的对手,运尽气力去和它苦斗。

臧克家的特点就是他不同于新月派、现代派诗人以及中国诗歌会诗人的“坚忍主义”。

他能严肃地面对现实生活中的险恶苦难,“从棘针尖上去认识人生”;他能带着倔强的精神沉着而有锋棱地去迎接磨难。

高考模拟试题(结合新高考考纲详细解说)高考风向标:山东省、海南省这一次模考也被视作新高考改革的风向标,未来高考的命题思路、考查形式、试题结构、出题重点,基本由此确定。

一、现代文阅读(35分)(一)现代文阅读I(本题共5小题,19分)考纲解读:(1)第1小题属于筛选和整合文中的信息;(2)第2小题是根据材料内容进行推断;(3)第3小题属于对材料外论据的分析。

三道选择题里前两道题都中规中矩,是保留了之前论述类文本的第1、3题,而第3题虽然考查了一个合理论据的选择,但是其实是之前论述类文本第2题的变种(借鉴天津卷实用类中题目)。

(4)第4小题问“材料二在论证上有哪些特点?请简要说明”属于一个比较新的问题,提示我们去关注论证方法、论证逻辑;(5)第5小题问“用传统意义上的文学性来评价科幻小说是否合理?请结合材料谈谈你的看法”,与“实用类文本”的传统问答题比较类似,选择立场自圆其说即可。

3. 文章字数现代文阅读Ⅰ材料阅读量2100字,阅读量增加较大。

需提高阅读效率,保证做题节奏。

一、现代文阅读(35分)(一)现代文阅读I(本题共5小题,19分)阅读下面的文字,完成1~5题。

材料一:在《论语》里孔子被描写成一个教育家。

从某种观点看来,也的确如此。

他期望他的弟子成为对国家、对社会有用的“成人”(《论语·宪问》),所以教给他们以经典为基础的各门知识。

作为教师,他觉得他的基本任务,是向弟子们解释古代文化遗产。

《论语》记载,孔子说他自己“述而不作”(《论语·述而》),就是这个缘故。

不过这只是孔子的一个方面,他还有另一方面,这就是,在传述传统的制度和观念时,孔子给予它们的解释,是由他自己的道德观推导出来的。

例如在解释“三年之丧”这种古老的礼制时,孔子说:“子生三年,然后免于父母之怀。

夫三年之丧,天下之通丧也。

”(《论语·阳货》换句话说,儿子的一生,至少头三年完全依赖父母,因此父母死后他应当以同样长的时间服丧,表示感恩。

还有在讲授经典时,孔子给它们以新的解释。

例如讲到《诗》,他强调它的道德价值时说:“《诗》三百,一言以蔽之,日‘思无邪’。

”(《论语·为政》)这样一来,孔子就不只是单纯地传述了,因为他在“述”里“作”出了一些新的东西。

这种以“述”为“作”的精神,被后世儒学传之永久,经书代代相传时,他们就写出了无数的注疏。

后来的《十三经注疏》,就是用这种精神对经书原文进行注释而形成的。

(摘编自冯友兰《孔子:第一位教师》)概况述而不作,材料一:向弟子解释传授古代文化遗产,并且由自己的道德观推导出来。

他在“述”里“作”出了一些新的东西,值得赞扬、学习和借鉴。

材料二:“述”的内涵非常丰富。

《说文解字》将“述”解释为“循”;在现代汉语中,“述”可以理解为“叙述”“陈述”“讲述”“论述”或“阐述”等等。

在《中庸》中,儒家德性“孝”的定义和“述”是相关的。

《中庸》:“夫孝者,善继人之志,善述人之事者也。

”如果我们将“孝”的这种解释和孔子在《论语·述而》第一章中的自我描述联系起来,“述”的深层含义便跃然纸上,也就是“述”表达了“孝”的德性。

孔子践履“孝”这种德性的对象是天。

《论语·八佾》讲到,“天下之无道也久矣,天将以夫子为木铎”。

孔子道德追寻的是天的使命。

对于孔子而言,他的工作就是传天道,兴天道。

在《论语·阳货》第十八章中,孔子说他不想再说话,但是他的弟子子贡说:“子如不言,则小子何述焉?”孔子回答:“天何言哉!四时行焉,百物生焉。

天何言哉!”从这段话中可以得出两点:第一,孔子述的是天道,天是最终的创造者;第二,孔子认为自己是天道的述者,子贡则将自己看作是孔子思想的述者。

孔子践履德性的活动表达了对天的“孝”,而子贡践履德性的活动则表达了对孔子的“孝”。

因此,孔子将他对经典的传承比作一个孝子做的事情。

儿子对父亲最大的孝是对父亲志向、事业、梦想的继承、实现和发扬光大。

同样孔子述的天道也是对天的孝。

对于孔子而言,他的智力活动是恢复天道,这就是对天尽孝。

在孔子那里,“孝”的含义涉及了延续文化传统和历史传承的义务。

孔子不是唯一把哲学活动与“孝”联结起来的人。

孔子与柏拉图早期的作品《游叙弗伦》对“孝”的定义殊途同归。

苏格拉底的诘问对象游叙弗伦得出“孝”是公正的一部分,“孝”是人类对上帝的侍奉。

苏格拉底认为自己的哲学活动就是对神灵的侍奉,自己的问答法就是对神灵的侍奉。

基于苏格拉底对上帝侍奉的论证,苏格拉底提供的答案就是进行哲学活动是对上帝真正的“孝”。

对哲学活动与孝的密切联系,亚里士多德也有所表述。

他在《尼各马可伦理学》中说,“孝”要求更加尊重真理而不是尊重你的朋友。

他认为“孝”的对象是真理,而不是上帝。

践行“孝”这一德性活动是追求哲学的严肃义务,因为追寻哲学是为了探寻真理。

孔子、苏格拉底、柏拉图、亚里士多德都把哲学活动和“孝”联结起来,尽管每一个人对“孝”的理解不同,这也反映了他们做哲学的方法不同。

苏格拉底通过诘问的方式审查人的信念;亚里士多德更多地是通过对前人理论的考察、批判发现真理;孔子则认为从事“孝”的活动就是对天道的传承。

(摘编自余纪元金小燕韩燕丽《“述而不作”何以成就孔子?》)材料二当中,孔子传承天命,传天道,兴天道,对天尽孝,就是“孝”的含义涉及了延续文化传统,和历史传承的义务。

值得肯定,赞扬,发扬光大。

材料三:“述而不作”的信条影响深远,达两千年之久,成为风气。

自孔子以后,儒家教育多遵从这一原则,以传授、注解经典为己任。

要从事这一学问,必然熟记经文才能言而有据。

因而,熟记经典成为学生的基本功。

孔子教育弟子是为了让他们从政,用子夏的话说是“学而优则仕”(《论语·子张》)。

隋唐以后,科举盛行,官方明确规定了读书人的出路,只有为官一途。

学校成为向科举输送考生的途径之一。

科举使用八股文体,专以四书五经命题,以儒家经典考学生,答案阐释以经典为准,不允许有超出范围的见解。

可以说,孔子“述而不作”的信条,使得他在教学中有偏重继承、轻视创新的倾向;伦理关系与师生关系的结合,造成学生对教师的依赖,这使人们从青少年时代起就减少或部分失去了探索未知的兴趣。

这样使得传统教育以教师解释、学生背诵为基本方式,因循以往,缺乏创新精神。

(摘编自李杨《“述而不作”与传统教育》)1.下列对材料相关内容的理解和分析,正确的一项是(3 分)A.《论语》中虽然记录孔子说自己“述而不作”,其实孔子在传述文化遗产的同时,也“作”了一些新的东西,后孔子时代的儒学都长期传承并发展着这种精神。

B.“述而不作”中的“述”内涵非常丰富,在古代辞书中解释为“循”,但在现代汉语中这一含义被“叙述”陈述”“讲述”“论述”或“阐述”等含义所取代。

C.在儒家经典著作《中庸》一书中,认为“孝”应包括“善述人之事也”,也就是说,“述而不作”中的“述”与“孝”是统一的,这种理解恰好切合孔子的观点。

D.“述而不作”的信条,后来成为儒学教育的一条重要原则,熟记经典成为学生的基本功,这一传统一直影响到后来的科举考试,并且命题答案均以四书五经为限。

D(A 材料- -第二段原文说“这种以*述’为作’的精神,被后世儒学传之永久”,并非“都”“发展”;B 材料二开头一段原文仅仅对“述”的古今含义做了客观摘录,并未说古代的含义被现代含义“所取代”;C 材料二第二段在对《中庸》中这句话的分析阐述时只是说“述'表达了‘孝’的德性”,但这句话并不包含这两者“统一”的意思。

)2.根据材料一和材料二,下列说法不正确的一项是(3 分)A.作为第一位教师,孔子期望把学生培养成对国家和社会有用的人;作为伟大的思想家,他认为从事“孝”的活动是对天道的传承。

B.孔子认为,儿子出生的头三年完全依赖父母,故父母死后孩子应以同样的时长服丧以表感恩,于是提出了“三年之丧”的礼制。

C.“孝”在儒家思想学说中占有着重要的地位,在孔子看来,“孝”不仅限于父母,也体现在对历史的传承和对文化传统的延续。

D.孔子、柏拉图、苏格拉底、亚里士多德等人都将哲学活动与“孝”联结起来,因做哲学的方法不同,对“孝”的理解也有差异。

3.下列说法中,可以作为论据来支撑材料二主要观点的一项是(3分)A.“上帝为每个人灵魂提供了选择机会:或是拥有真理,或是得到安宁。

你可以任选其一,但不能兼而有之。

”B.“倘若没有天地,哪里会有人类生存发展的空间。

因此,敬天祈福正是对天地自然献上的一份崇高敬意。

”C.“优秀传统文化是一个国家、一个民族传承和发展的根本,如果丟掉了,就割断了精神命脉。

”D.“孝子之事亲也,居则致其敬,养则致其乐,病则致其忧,丧则致其哀,祭则致其严。

五者备矣,然后能事亲。

”解说:C(要正确选出支撑材料二主要观点的语句,首先要明确材料二的主要观点。

从阅读材料二不难发现,这段材料主要是就孔子的“孝”展开论述的,而论述的中心就是延续文化传统和历史传承。

因此,该题提供的四个选项只有C 可以作为这一论点的论据。

A 强调要拥有真理;B 表达对天地自然的敬畏;D 只是就孝顺父母宗亲而言的。

)4.材料二在论证上有哪些特点特色?请简要说明。

(4 分)(1)紧紧围绕中心论点展开论述,主要以孔子的言行为论据;(2)采用递进式的论证结构,层层深入,逻辑严密;(3)论证综合运用了多种论证方法,如引证法、例证法、类比论证等。

评分标准:答出- -点给1分,答出两点给2分,答出三点给4分。

如第1点只答出“主要以孔子的言行为论据”,第2点只答出“递进式的论证结构”也算对;第3点必须答出具体的论证方法.答出两种方法也可,但必须包含“类比论证”,否则不给分。

如有其他答案,只要言之成理,也可酌情给分。

都不会:(1)论证包括论证结构和论证方法。

常见的论证结构有并列式、递进式、对照式。

(2)论证有立论和驳论两种方式。

常见的论证方法有举例论证、引用论证、对比论证、比喻论证等。

5.对影响两千年之久的孔子“述而不作”的信条,你是如何看待的?请结合材料谈谈你的认识。

(6 分)"述而不作”有其积极的一面,孔子向弟子们解释古代文化遗产,对文化经典的传承以及要求学生熟背文化经典都是值得提倡和继承的;但教学中偏重继承,限制学生探索未知的兴趣和创新精神,又有局限性。

评分标准:答出一点给3分,答出两点得6分。

两点必须是从“积极”和“局限”两个方面来回答。

意思答对即可。

如有其他答案,只要言之成理,也可酌情给分。

二、现代文学阅读Ⅱ文本选择(考纲解读)1.在19年考纲中明确规定了“小说、散文、诗歌、戏剧”,这里诗歌专指现代诗歌。

明确指向——所学有可能所考。

2.山东卷整体阅读数量减少,这里很大程度上是文体的原因(新诗),阅读总量应该与原来保持相仿(海南卷小说)。

3.改题型材料选取,未来可能”小说”“诗歌”“散文”“戏剧”会在同一试卷中不同年份交替考查或相同年份的不同试卷中同时考查。
