A 2018 statistic shows that women nowadays hold just 5.8 percent of CEOs positions at S&P 500 companies, according to Catalyst.While i t’s not a huge shock that women are somewhat underrepresented in leadership positions, what is surprising though, is the fact that females may actually be better suited to lead in almost every area, at least according to new findings from the BI Norwegian Business School.In their research, Professor Martinsen and Professor Lars Glas surveyed (调查) 2,900 managers with a special focus on personality types. The results were clear: Women scored higher than men in four of the five major leadership-centric categories.While some people believe that men inherently make better leaders — probably because they picture a leader with a commanding voice, which is more typical of men than women — this piece of research suggests that women are better at methodical management and goal-setting, openness, sociability and supportiveness, as well as ability to communicate clearly.There was one area in which men scored higher than women, though, and that was on emotional stability and ability to face job-related pressure and stress. The results suggest that women are more sensitive to the effects of high-pressure or highly emotional situations.Obviously, it’s important to consider individual(个人的) differences. Anyone, regardless of gender, may be an inspiring leader and a competen t boss. So next time you’re hiring for a management position, you just might want to give the resumes(简历) from female candidates a harder look.1.What makes us shocked much at leadership positions?A.Women are worse than men.B.Men take almost all high positions.C.There is a huge gap between genders.D.Women might behave better in every field.2.Which of the following can best replace the underlined word ‘‘inherently” in paragraph 4?A.properlyB.potentiallyC.naturallyD.normally3.Which of the following may be the best title of this text?A.How We Can Figure Out The Boss.B.Why Women Are Better Than MenC.Why Women Make Better BossesD.How We Can Tell Gender Difference4.Who might have special interest in this article?A.Job hunters.B.Employers.C.Employees.D.University students.3、On a February afternoon in a classroom, Taylor came face to face with a cow-but it was all in her head.A virtual(虚拟的)reality headset had transported her and her classmates to a farm 250 miles away and for them, the technology means field trips are no longer limited by a bus ride.On any given day, students nationwide walk through fields, dive into deep sea, and observe medical operations by using such headset. It's another way to attract the iPhone generation of students and improve their understanding and their grades.Richard Lamb is a scientist working at Buffalo Science Lab. In the lab, the physical effects of virtual reality become clear as participants experience motion (运动) sickness without m oving. “Some of the research we’re doing has shown that what you experience in virtual reality has very similar responses that you would get if you were doing the actual activity, ” Lamb said.It's unknown how many classrooms have or will adopt the technology, but experts say it's still relatively rare. While individual headsets that require a user’s phone can cost as little as $20 or $30, systems and software for classes will cost thousands of dollars. Early complaints about a lack of good software are fading as more companies enter the market, but the rules for use haven't necessarily caught up with the technology.In New York, virtual lab experiments don’t count toward the state's hands-on lab time requirements. Even so, the sciences are an area w here virtual reality holds particular promise for classrooms. “The big gest impediment is going to be the quality of that experience, and that means how closely it mimics (模仿) the physical world, ” said David Evans, a scientist. “ Doing dangerous things and running into a lot more cases represent a huge learning opportunity.”Lamb agree d. “Too often in schools, when we do things in labs, you mix things together and you get this outcome. And if you don't get that outcome, you did something wrong, but we d on't have enough resources for you to redo it,” he said. “In virtual reality, all I do is on the computer. I don’t have to actually use chemicals.”1.What does a virtual reality headset really help the students do?A.Take some exercise.B.Perform an operation.C.Go for a bus ride.D.Have different experiences.2.The technology is rarely used in classrooms mainly because ________.A.students show little interest in itB.it's too expensive for users to afford itC.supporting software is inaccessible yetD.it's inconvenient to be operated by students3.Which word can replace the underlined wor d “impediment” in Paragraph 5?A.Opportunity.B.Difficulty.C.Surprise.D.Disappointment.4.Which of the following statements do both Lamb and Evans agree with?A.This technology can save students a lot of time.B.This technology is safe when used in experiments.C.This technology can enrich students' learning experiences.D.This technology can produce a better result in real life.4、No student of a foreign language needs to be told that grammar is complex. By changing the order of the words and by adding a range of auxiliary verbs (助动词) and suffixes (后缀), we can turn a statement into a question, state whether an action has taken place or is soon to take place, and perform many other word tricks to convey different meanings. However, the question which many language experts can’t understand and explain is—who created grammar?Some recent languages evolved due to the Atlantic slave trade. Since the slaves didn’t know each other’s languages, they developed a make-shift language called a pidgin. Pidgins are strings of words copied from the language of the landowners. They have little in the way of grammar, and speakers need to use too many words to make their meaning understood. Interestingly, however, all it takes for a pidgin to become a complex language is for a group of children to be exposed to it at the time when they learn their mother tongue. Slave children didn’t simply copy the strings of words used by their elders. They adapted their words to create an expressive language. In this way complex grammar systems which come from pidgins were invented.Further evidence can be seen in studying sign languages for the deaf. Sign languages are not simply a group of gestures; they use the same grammatical machinery that is found in spoken languages. The creation of one such language was documented quite recently in Nicaragua. Previously, although deaf children were taught speech and lip reading in the classrooms, in the playgrounds they began to invent their own sign system, using the gestures they used at home. It was basically a pidgin and there was no consistent grammar. However, a new system was born when children who joined the school later developed a quite different sign language. It was based on the signs of the older children, but it was shorter and easier to understand, and it had a large range of special use of grammar to clarify the meaning. What’s more, they all used the signs in the same way. So the original pidgin was greatly improved.Most experts believe that many of the languages were pidgins at first. They were initially used in different groups of people without standardization and gradually evolved into a widely accepted system. The English past tense—“ed” ending—may have evolved from the verb “do”. “It ended” may once have been “It end-did”. It seems that children havegrammatical machinery in their brains. Their minds can serve to create logical and complex structures, even when there is no grammar present for them to copy.1.What can be inferred about the slaves’ pidgin language?A.It was difficult to understand.B.It came from different languages.C.It was created by the landowners.D.It contained highly complex grammar.2.What is the characteristic of the new Nicaraguan sign language?A.No consistent signs were used for communication.B.Most of the gestures were made for everyday activities.C.The hand movements were smoother and more attractive.D.The meaning was clearer than the previous sign language.3.Which idea does the author present in the last paragraph?A.English grammar of past tense system is inaccurate.B.Children say English past tense differently from adults.C.The thought that English was once a pidgin is acceptable.D.Experts have proven that English was created by children.4.What is the best title for the passage?A.The Creators of GrammarB.The History of LanguagesC.Why Pidgins Came into BeingD.How Grammar Systems Are Used5、Some Ways to Increase Your Reading SpeedDo you have a lot of reading to do before class tomorrow? Here are some ways to help increase your reading speed.1. Stop the Inner SpeechOne’s inner monologue is an extremely common trait among readers.①__________ It is the biggest obstacle that gets in the way of you being able to increase your reading speed.2. Do Not Reread the Words on the PageYou most likely do this without even realizing that you are doing it, which makes it a bit of a difficult habit to break out of. ②__________ Keep your fingers running back and forth across the page, without stopping or going back.3. Set a GoalHolding yourself accountable will better ensure you stick with your reading and your timer tests. Give yourself a goal of a certain number of pages to read each day/week/etc. , and stick to it. When you reach it, treat yourself. ③__________4. Work on Improving Your VocabularyThink about it: You’re reading along,and then you run into a word you don’t know. Do you skip it?④__________ Do you stop to look it up? If you work on improving your vocabulary, you will know more words. The more words you add to your stock, the faster you read. The faster you read, the more you can read. It may be clear, but it's important.5. Skim the Main Points FirstFinally, when you're in a real time-crunch and need to get something read by tomorrow, take a deep breath and calm down. Open the book, and take some time reading over all the main points. Read the table of contents. Read the subtitles. Read the captions under the diagrams. ⑤__________A. Self-encouragement never hurts anyone!B. Do you try to figure it out by context?C. Your brain still processes information.D. Get an overall feel for the chapter.E. A reader should do more reading.F. The easiest way is to use your finger to guide you along.G. It is the process of speaking the words in your head as you read.6、阅读下面短文,从短文后所给各题的四个选项中,选出可填入空白处的最佳选项。

2019年全国高考语文模拟试卷二附答案

2019年高考语文模拟试卷二一、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，完成1——3题文艺是一种表现而不是一种卖弄。

表现的理想是文情并茂，“充实而有光辉”，虽经苦心雕琢，却是天衣无缝，自然熨贴，不现勉强作为痕迹。

一件完美的艺术品像一个大家闺秀，引人注目而却不招邀人注目，举止大方之中仍有她的贞静幽闲，有她的高贵的身份。

艺术和人一样，有它的品格，我们常说某种艺术品高，某种艺术品低，品的高低固然可以在多方面见出，最重要的仍在作者的态度。

品高的是诚于中，形于外，表里如一的高华完美。

品低的是内不充实而外求光辉，存心卖弄，像小家娼妇涂脂抹粉，招摇过市，眉挑目送的样子。

文艺的卖弄有种种方式。

最普遍的是卖弄词藻，只顾堆砌漂亮的字眼，显得花枝招展，绚烂夺目，不管它对于思想情感是否有绝对的必要。

从前骈俪文犯这毛病的最多，现在新进作家也有时不免。

其次是卖弄学识。

文艺作者不能没有学识，但是他的学识须如盐溶解在水里，尝得出味，指不出形状。

有时饱学的作者无心中在作品中流露学识，我们尚不免有“学问汩没性灵”之感，至于有意要卖弄学识，如暴发户对人夸数家珍，在寻常人如此已足见趣味低劣，在文艺作品中如此更不免令人作呕了。

过去中国文人犯这病的最多，在诗中用僻典，谈哲理，写古字，都是最显著的例。

新文学作家常爱把自己知道比较清楚的材料不分皂白地和盘托出，不管它是否对于表现情调、描写人物或是点明故事为绝对必需，写农村就把农村所有的东西都摆进去，写官场也就把官场所有的奇形怪状都摆进去，有如杂货店，七零八落的货物乱堆在一起，没有一点整一性，连比较著名的作品如赛珍珠的《大地》，吴趼人的《二十年来目睹之怪现状》之类均不免此病，这也还是卖弄学识。

第三是卖弄才气。

文艺作者固不能没有才气，但是逞才使气，存心炫耀，仍是趣味低劣。

像英国哲学家休谟和法国诗人魏尔兰所一再指示的，文学不应只有“雄辩”（eloquence），而且带不得雄辩的色彩。

2019年浙江高三上学期高考模拟英语试卷(仿真训练卷(二))-学生用卷

2019年浙江高三上学期高考模拟英语试卷（仿真训练卷（二））-学生用卷一、阅读理解（共10小题，每小题2.5分，共25分）1、【来源】 2019年浙江高三上学期高考模拟（A篇）第21~23题7.5分Running a marathon is not easy. It takes hard work, practice, and patience. After all, to run a marathon, you have at run 26.2 miles by foot! Think about it this way: 26. 2 miles is the same as running the length of a football field more than460 times. It takes most people four or five hours to finish.By the age of 30, Lea Tambellini had run more than five marathons and had no plans to stop. She had always been an athlete. When she was in high school, she swam on her school's swim team and ran to stay healthy and active. Her mom and dad ran marathons, and when she was 22, they helped her train for her first marathon.Lea's first marathon took place in Cincinnati, Ohio, and was called "The Flying Pig". "I was very nervous" she said, "but I had my mom there, so that helped. "Running the race was hard, but the hardest part was when she ran past a cookie factory and smelled cookies at mile 18."I just wanted to be done, "she said. "TAL#NBSP I was spent, but my mom kept me going. It was already her 15th marathon."Today, thousands of people run marathons every year. Runners train for months to get ready. 'To prepare for one of the marathons, Lea ran four to five times every week. On weekdays, she completed shorter runs, five or six miles at most. But on the weekends she ran long distances-13 miles, 15 miles, and 20 miles!"I don't mind training because I get excited about working toward something. And I love running with a group of friends and working toward the goal together. But it does take a lot of time."Running a marathon is a great achievement. "It's a great feeling of accomplishment and nothing feels as wonderful as reaching my goal when I cross the finish line, " Lea explained."I can't wait for the next one!"(1) What contributed to Lea becoming a marathon runner?A. Her great patience and life ambition to be a successful athlete.B. Her strong interest in swimming and long-distance running.C. Her athletic experience and her parents' guidance.D. Her love for running with friends and achieving a goal together.(2) What does Lea mean by saying "I was spent" in Paragraph 3?A. I was extremely exhausted.B. I felt like quitting my sporting career.C. I was feeling increasingly nervous.D. I was overcome by hunger.(3) How did Lea's feeling of running a marathon change over they ears?A. From curiosity to enthusiasm.B. From nervousness to excitement.C. From thrill to boredom.D. From delight to disappointment.2、【来源】 2019年浙江高三上学期高考模拟（B篇）第24~27题10分2018年浙江绍兴柯桥区高三二模第27~30题10分(每题2.5分)Kids naturally need unstructured time to play, to discover their own interests, to goof around（混时间）, or to try things out. Some kids in our society have almost no time left to themselves, often because their parents are overscheduled themselves, or their parents are so concerned about kids' achievements that the kids are constantly doing some structured activities. Some parents want their kids to constantly be working on their personal portfolios（文件包） so they can get into college, prep school or preschool. But if kids don't have any down time, they'll burn out quickly.You'd be amazed at how much kids mature, learn and improve when they are given time to just be. Kids need to learn what it is like to be bored and how to entertain themselves. They need time to play with all of those presents they just got from the holiday. They need to make mistakes on their own, discover new ways to do things and nurture their interests and talents. This is called learning.In our house, eating, sleeping mostly）, and a few chores and schoolwork are fairly structured. There are occasional errands and playdates, appointments and scout meetings. But most days, our kids have several hours in which they choose what to do. We guide them toward positive ways to spend time, but for the most part, they get to choose. I think this is a healthy thing.I won't go so far as to say that parents who overschedule their kids are stealing their kids' childhoods. I'm sure those kids are getting to do some great things that not every other kid gets to do. But the kids are missing out on a vital piece of childhood: running amok （横冲直撞）, not necessarily running all over town on their own, but having time that is theirs, that they get to organize and fill. Kids need to learn how to make choices and learn about the bad and good consequences that come along with their choices.(1) Why are the kids constantly doing some structured activities?A. They like structured activities very much.B. Their parents expect them to achieve more.C. Their parents are worried about their safety.D. Structured activities suit children's interests.(2) Which of the following sayings can convey the closest meaning of the underlined sentence in the first paragraph?A. No pains, no gains.B. Look before you leap.C. Honesty is the best policy.D. All work and no play makes Jack a dull boy.(3) In the writer's opinion, the kids.A. should be guided to learnB. should do some great thingsC. should have time that is theirsD. should be allowed to run all over town(4) The main purpose of the passage is to.A. concern the healthy growth of kidsB. provide evidence of how kids liveC. criticize parents on unwise parentingD. give a lecture on kids' time management3、【来源】 2019年浙江高三上学期高考模拟（C篇）第28~30题7.5分Do we organize our thoughts in different ways because of the culture we belong to? If it is so, how can we describe those differences?The idea of different "cultural thought patterns" was first put forward by an American professor, Robert Kaplan, in the 1960s. He had been looking at the writing style of non-native students at his university in California. He found that the writing style changed systematically, according to the cultural origins of the students.For example, in his opinion, native speakers of English usually went "straight to the point" However, speakers of Semitic languages（such as Arabic and He brew）kept back tracking, and then returned to the point. Speakers of oriental languages （such as Chinese）were likely to approach the topic only little by little, as if they were moving around it in circled. Speakers of Romance languages（such as French and Spanish）were likely to stay away from the point, making it harder for readers to follow. Speakers of slap languages（such as Russian）often included ideas which didn't seem to be connected in any way to the development of the article.This view attracted a lot of attention as soon as it was expressed. People said it was not based on enough evidence at all, and it was TAL#NBSP biased because it was in supports English（which seemed to offer the "most useful" way of presenting the point of view）. Russian students, in particular, did not agree with the idea Kaplan had of them.But Kaplan's work at least reminded us that people from different cultural backgrounds do have different ways of presenting ideas, or telling stories, and that, even if these differences are difficult, and perhaps impossible to sort out, just knowing that they exist can help us to understand and appreciate each other better.(1) What is the author' s purpose in writing Paragraph 2?A. To present his own idea.B. To introduce Robert Kaplan.C. To draw readers to the topic.D. To provide examples of the topic.(2) What does the underlined word "biased" in Paragraph 4 probably mean?A. Wrong.B. Usual.C. Direct.D. Humorous.(3) Which of the following is the best title for the text?A. Thinking across culturesB. Skills for speaking wellC. Reading between linesD. Differences in cultures.二、七选五（共5小题，每小题2分，共10分）4、【来源】 2019年浙江高三上学期高考模拟第31~35题10分根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。

But at Union Station in Los Angeles last month, a board went up with dollar bills attached to it with pins and a sign that read, "Give What You Can, Take What You Need."People quickly caught on. And while many took dollars, many others pinned their own cash to the board. “People of all ages, races, and socio-economic(社会经济的)backgrounds gave and took, ”said Tyler Bridges of The Toolbox, which created the project. "We even had a bride in her wedding dress come up to the board and take a few dollars." Most of the bills on the board were singles, but a few people left fives, tens and even twenties. The video clip(片段)shows one man who had found a $ 20 bill pinning it to the board.“What I can say for the folks that gave the most, is that they were full of smiles,” Bridges said. “There’s a certain feeling that giving can do for you and that was apparent in those that gave the most." Most people who took dollars took only a few, but Bridges said a very small number took as much as they could.While the clip might look like part of a new ad campaign, Bridges said the only goal was to show generosity and sympathy. He added that he hopes people in other cities might try similar projects and post their own videos on the Internet.“After all, everyone has bad days and good days," he said. “Some days you need a hel ping hand and some days you can be the one giving the helping hand.”24. What does the expression "money with no strings attached" in paragraph 1 mean?A. Money spent without hesitation.B. Money not legally made.C. Money offered without conditions.D.

To promote kindness and sympathy.III.说明文1. 【2019·全国卷I，C】As data and identity theft becomes more and more common, the market is growing for biometric(生物测量)technologies—like fingerprint scans—to keep others out of private e-spaces. At present, these technologies are still expensive, though.Researchers from Georgia Tech say that they have come up with a low-cost device(装置)that gets around this problem: a smart keyboard. This smart keyboard precisely measures the cadence(节奏)with which one types and the pressure fingers apply to each key. The keyboard could offer a strong layer of security by analyzing things like the force of a user's typing and the time between key presses. These patterns are unique to each person. Thus, the keyboard can determine people's identities, and by extension, whether they should be given access to the computer it's connected to—regardless of whether someone gets the password right.It also doesn't require a new type of technology that people aren't already familiar with. Everybody uses a keyboard and everybody types differently.In a study describing the technology, the researchers had 100 volunteers type the word “touch”four times using the smart keyboard. Data collected from the device could be used to recognize different participants based on how they typed, with very low error rates. The researchers say that the keyboard should be pretty straightforward tocommercialize and is mostly made of inexpensive, plastic-like parts. The team hopes to make it to market in the near future.28. Why do the researchers develop the smart keyboard?A. To reduce pressure on keys.B. To improve accuracy in typingC. To replace the password system.D. To cut the cost of e-space protection.29. What makes the invention of the smart keyboard possible？A. Computers are much easier to operate.B. Fingerprint scanning techniques develop fast.C. Typing patterns vary from person to person.D. Data security measures are guaranteed.30. What do the researchers expect of the smart keyboard？all 1o soisgitieoco oll.A. It'll be environment-friendly.B. It'll reach consumers soon.C. It'll be made of plastics.D. It'll help speed up typing.31. Where is this text most likely from?A. A diary.B. A guidebookC. A novel.D. A magazine.2. 【2019·全国卷I，D】During the rosy years of elementary school(小学), I enjoyed sharing my dolls and jokes, which allowed me to keep my high social status. I was the queen of the playground. Then came my tweens and teens, and mean girls and cool kids. They rose in the ranks not by being friendly but by smoking cigarettes, breaking rules and playing jokes on others, among whom I soon found myself.Popularity is a well-explored subject in social psychology. Mitch Prinstein, a professor of clinical psychology sorts the popular into two categories: the likable and the status seekers. The lik ables’ plays-well-with-others qualities strengthen schoolyard friendships, jump-start interpersonal skills and, when tapped early, are employed ever after in life and work. Then there’s the kind of popularity that appears in adolescence: status born of pow er and even dishonorable behavior.Enviable as the cool kids may have seemed, Dr. Prinstein’s studies show unpleasant consequences. Those who were h ighest in status in high school, as well as those least liked in elementary school, are “most likely toengage(从事)in dangerous and risky behavior.”In one study, Dr. Prinstein examined the two types of popularity in 235 adolescents, scoring the least liked, the most liked and the highest in status based on student surveys(调查研究). “We found that the least well-liked teenshad become more aggressive over time toward their classmates. But so had those who were high in status. It clearly showed that while likability can lead to healthy adjustment, high status has just the opposite effect on us."Dr. Prinstein has also found that the qualities that made the neighbors want you on a play date-sharing, kindness, openness — carry over to later years and make you better able to relate and connect with others.In analyzing his and other research，Dr. Prinstein came to another conclusion: Not only is likability related to positive life outcomes, but it is also responsible for those outcomes, too. "Being liked creates opportunities for learning and for new kinds of life experiences that help somebody gain an advantage, ” he said.32. What sort of girl was the author in her early years of elementary school?A. Unkind.B. Lonely.C. Generous.D. Cool.33. What is the second paragraph mainly about？A. The classification of the popular.B. The characteristics of adolescents.C. The importance of interpersonal skills.D. The causes of dishonorable behavior.34. What did Dr. Prinstein’s study find about the most liked kids?A. They appeared to be aggressive. B. They tended to be more adaptable. C. They enjoyed the highest status. D. They performed well academically. 35. What is the best title for the text? A. Be Nice-You Won’t Finish Last B. The Higher the Status, the Beer C. Be the Best-You Can Make It D. More Self-Control, Less Aggressiveness 4. 【2019·全国卷II，D】Bacteria are an annoying problem for astronauts. The microorganisms(微生物) from our bodies growuncontrollably on surfaces of the International Space Station, so astronauts spend hours cleaning them up each week. How i s NASA overcoming this very tiny big problem? It’s turning to a bunch of high school kids. But not just any kids. It depending on NASA HUNCH high school class, like the one science teachers Gene Gordon andDonna Himmelberg lead at Fairport High School in Fairport, New York.HUNCH is designed to connect high school classrooms with NASA engineers. For the past two years, Gordon’s students have been studying ways to kill bacteria in zero gravity, and they think they’re close to a solution(解决方案). “We don’t give the students any breaks. They have to do it just like NASA engineers,” says Florence Gold, a project manager.“There are no tests,” Gordon says. “There is no graded homework. There almost are no grades, other than‘Are you working towards your goa l?’ Basically, it’s ‘I’ve go t to produce this product and then, at the end of year, present it to NASA.’ Engineers come and really do an in-person review, and…it’s not a very nice thing at time. It’s a hard business review of your product.”Gordon says the HUNCH program has an impact(影响) on college admissions and practical life skills. “These kids are so absorbed in their studies that I just sit back. I don’t teach.” And that annoying bacteria? Gordon says his students are emailing daily with NASA engineers about the problem, readying a workable solution to test in space.32. What do we know about the bacteria in the International Space Station?A. They are hard to get rid of.B. They lead to air pollution.C. They appear different forms.D. They damage the instruments.33. What is the purpose of the HUNCH program?A. To strengthen teacher-student relationships.B. To sharpen students’ communication skills.C. To allow students to experience zero gravity.D. To link space technology with school education34. What do the NASA engineers do for the students in the program?A. Check their product.B. Guide project designsC. Adjust work schedules.D.

It had been known for a long time that Yellowstone was volcanic in nature — that's what accounted for all its hot springsand other steamy features. But Christiansen couldn't find the Yellowstone volcano anywhere.Most of us，when we talk about volcanoes，think of the classic cone(圆锥体)shapes of a Fuji or Kilimanjaro，which are created when erupting magma(岩浆)piles up. These can form remarkably quickly. In 1943，a Mexican farmer was surprised to see smoke rising from a small part of his land. In one week he was the confused owner of a cone five hundred feet high. Within two years it had topped out at almost fourteen hundred feet and was more than half a mile across. Altogether there are some ten thousand of these volcanoes on Earth，all but a few hundred of them extinct. There is，however，a second les known type of volcano that doesn't involve mountain building. These are volcanoes so explosive that they burst open in a single big crack，leaving behind a vast hole，the caldera. Yellowstone obviously was of this second type，but Christiansen couldn't find the caldera anywhere.Just at this time NASA decided to test some new high-altitude cameras by taking photographs of Yellowstone.A thoughtful official passed on some of the copies to the park authorities on the assumption that they might make a nice blow-up for one of the visitors' centers. As soon as Christiansen saw the photos，he realized why he had failed to spot the caldera; almost the whole park-2.2 million acres—was caldera. The explosion had left a hole more than forty miles across—much too huge to be seen from anywhere at ground level. At some time in the past Yellowstone must have blown up with a violence far beyond the scale of anything known to humans.58. What puzzled Christiansen when he was studying Yellowstone？A. Its complicated geographical features.B. Its ever-lasting influence on tourism.C. The mysterious history of the park.D. The exact location of the volcano.59. What does the second-paragraph mainly talk about？A. The shapes of volcanoes.B. The impacts of volcanoes.C. The activities of volcanoes.D. The heights of volcanoes.60. What does the underlined word "blow-up" in the last paragraph most probably mean？A. Hot-air balloon.B. Digital camera.C. Big photograph.D. Bird's view.10. 【2019·浙江卷，C】California has lost half its big trees since the 1930s, according to a study to be published Tuesday and climatechange seems to be a major factor(因素).The number of trees larger than two feet across has declined by 50 percent on more than 46, 000 square miles of California forests, the new study finds. No area was spared or unaffected, from the foggy northern coast to the Sierra Nevada Mountains to the San Gabriels above Los Angeles. In the Sierra high country, the number of big trees has fallen by more than 55 percent; in parts of southern California the decline was nearly 75 percent.Many factors contributed to the decline, said Patrick Mclntyre, an ecologist who was the lead author of the study. Woodcutters targeted big trees. Housing development pushed into the woods. Aggressive wildfire control has left California forests crowded with small trees that compete with big trees for resources(资源).But in comparing a study of California forests done in the 1920s and 1930s with another one between 2001 and 2010, Mclntyre and his colleagues documented a widespread death of big trees that was evident even in wildlands protected from woodcutting or development.The loss of big trees was greatest in areas where trees had suffered the greatest water shortage. The researchers figured out water stress with a computer model that calculated how much water trees were getting in comparison with how much they needed, taking into account such things as rainfall, air temperature, dampness of soil, and the timing of snowmelt(融雪).Since the 1930s, Mclntyre said, the biggest factors driving up water stress in the state have been rising temperatures, which cause trees to lose more water to the air, and earlier snowmelt, which reduces the water supply available to trees during the dry season.27. What is the second paragraph mainly about?A. The seriousness of big-tree loss in California.B. The increasing variety of California big trees.C. The distribution of big trees in California forests.D. The influence of farming on big trees in California.28. Which of the following is well-intentioned but may be bad for big trees?A. Ecological studies of forests.B. Banning woodcutting.C. Limiting housing development.D. Fire control measures.29. What is a major cause of the water shortage according to Mclntyre?A. Inadequate snowmelt.B. A longer dry season.C. A warmer climate.D. Dampness of the air.30. What can be a suitable title for the text?A. California's Forests: Where Have All the Big Trees Gone?B. Cutting of Big Trees to Be Prohibited in California SoonC. Why Are the Big Trees Important to California Forests?D. Patrick Mclntyre: Grow More Big Trees in CaliforniaIV.议论文1. 【2019·全国卷II，C】Marian Bechtel sits at West Palm Beach’s Bar Louie counter by herself, quietly reading her e-book as she waits for her salad. What is she reading? None of your business! Lunch is Bechtel’s “me” time. And like more Americans, she’s not alone.A new report found 46 percent of meals are eaten alone in America. More than half(53 percent)have breakfast alone and nearly half(46 percent)have lunch by themselves. Only at dinnertime are we eating together anymore，74 percent，according to statistics from the report.“I prefer to go out and be out. Alone，but together，you know？”Bechtel said，looking up from her book. Bechtel，who works in downtown West Palm Beach，has lunch with coworkers sometimes，but like many of us，too often works through lunch at her desk. A lunchtime escape allows her to keep a boss from tapping her on the shoulder. She returns to work feeling energized. “Today，I just wanted some time to myself，”she said.Just two seats over，Andrew Mazoleny，a local videographer，is finishing his lunch at the bar. He likes that he can sit and check his phone in peace or chat up the barkeeper with whom he's on a first-name basis if he wants to have a little interaction(交流). “I reflect on how my day's gone and think about the rest of the week,” he said. “It's a chance for self-reflection, You return to work recharged and with a plan.”That freedom to choose is one reason more people like to eat alone. There was a time when people may have felt awkward about asking for a table for one，but those days are over. Now，we have our smartphones to keep us company at the table. “It doesn't feel as alone as it may have before al the advances in technology,” said Laurie Demerit，whose company provided the statistics for the report.28. What are the statistics in paragraph 2 about?A. Food varietyB. Eating habits.C. Table manners.D. Restaurant service.29. Why does Bechtel prefer to go out for lunch?A. To meet with her coworkers.B. To catch up with her work.C. To have some time on her own.D. To collect data for her report.30. What do we know about Mazoleny?A. He makes videos for the bar.B. He’s fond of the food at the bar.C. He interviews customers at the bar.D. He’s familiar with the barkeeper.31. What is the text mainly about?A. The trend of having meals alone.B. The importance of self-reflection.C. The stress from working overtime.D. The advantage of wireless technology.2. 【2019·全国卷III，B】For Western designers, China and its rich culture have long been an inspiration for Western creative."It's no secret that China has always been a source(来源)of inspiration for designers," says Amanda Hill, chief creative officer at A+E Networks, a global media company and home to some of the biggest fashion(时尚)shows.Earlier this year, the China Through A Looking Glass exhibition in New York exhibited 140 pieces ofChina-inspired fashionable clothing alongside Chinese works of art, with the aim of exploring the influence of Chinese aesthetics(美学)on Western fashion and how China has fueled the fashionable imagination for centuries. The exhibition had record attendance, showing that there is huge interest in Chinese influences."China is impossible to overlook," says Hill. "Chinese models are the faces of beauty and fashion campaigns that sell dreams to women all over the world, which means Chinese women are not just consumers of fashion —they are central to its movement. "Of course, only are today's top Western designers being influenced byChina-some of the best designers of contemporary fashion are themselves Chinese." Vera Wang, Alexander Wang, Jason Wu are taking on Galiano, Albaz, Marc Jacobs-and beating them hands down in design and sales," adds Hil.For Hill, it is impossible not to talk about China as the leading player when discussing fashion. "The most famous designers are Chinese, so are the models, and so are the consumers," she says. "China is no longer justanother market; in many senses it has become the market. If you talk about fashion today, you are talking about China-its influences, its direction, its breathtaking clothes, and how young designers and models are finally acknowledging that in many ways."24. What can we learn about the exhibition in New York?A. It promoted the sales of artworks.B. It attracted a large number of visitors.C. It showed ancient Chinese clothes.D. It aimed to introduce Chinese models.25. What does Hill say about Chinese women?A. They are setting the fashion.B. They start many fashion campaigns.C. They admire super models.D. They do business all over the world.26. What do the underlined words "taking on" in paragraph 4 mean?A. learning fromB. looking down onC. working withD. competing against27. What can be a suitable title for the text?A. Young Models Selling Dreams to the WorldB. A Chinese Art Exhibition Held in New YorkC. Differences Between Eastern and Western AestheticsD. Chinese Culture Fueling International Fashion Trends3. 【2019·天津卷，D】Would you BET on the future of this man？He is 53 years old. Most of his adult life has been a losing struggle against debt and misfortune. A war injury has made his left hand stop functioning，and he has often been in prison. Driven by heaven-knows-what motives，he determines to write a book.The book turns out to be one that has appealed to the world for more than 350 years. That former prisoner was Cervantes，and the book was Don Quixote（《堂吉诃德》）. And the story poses an interesting question: why do some people discover new vitality and creativity to the end of their days，while others go to seed long before？We've all known people who run out of steam before they reach life's halfway mark. I'm not talking about those who fail to get to the top. We can't all get there. I'm talking about people who have stopped learning on growing because they have adopted the fixed attitudes and opinions that all too often come with passing years.Most of us，in fact，progressively narrow the variety of our lives. We succeed in our field of specialization and then become trapped in it. Nothing surprises us. We lose our sense of wonder. But，if we are willing to lean，the opportunities are everywhere.The things we learn in maturity seldom involve information and skills. We learn to bear with the things wecan't change. We learn to avoid self-pity. We learn that however much we try to please，some people are never going to love us-an idea that troubles at first but is eventually relaxing.With high motivation and enthusiasm，we can keep on learning. Then we will know how important it is to have meaning in our life. However，we can achieve meaning only if we have made a commitment to something larger than our own little egos（自我），whether to loved ones，to fellow humans，to work，or to some moral concept.Many of us equate（视……等同于）“commitment” with such “caring” occupations as teaching and nu rsing. But doing any ordinary job as well as one can is in itself an admirable commitment. People who work toward such excellence whether they are driving a truck，or running a store-make the world better just by being the kind of people they are. They've learned life's most valuable lesson.51. The passage starts with the story of Cervantes to show that_________.A. loss of freedom stimulates one's creativityB. age is not a barrier to achieving one's goalC. misery inspires a man to fight against his fateD. disability cannot stop a man's pursuit of success52. What does the underlined part in Paragraph 3 probably mean？A. End one's struggle for liberty.B. Waste one's energy taking risks.C. Miss the opportunity to succeed.D. Lose the interest to continue learning.53. What could be inferred from Paragraph 4？A. Those who dare to try often get themselves trapped.B. Those who tend to think back can hardly go ahead.C. Opportunity favors those with a curious mind.D. Opportunity awaits those with a cautious mind.54. What does the author intend to tell us in Paragraph 5？A. A tough man can tolerate suffering.B. A wise man can live without self-pityC. A man should try to satisfy people around him.D. A man should learn suitable ways to deal with life55. What is the author's purpose in writing the passage？A. To provide guidance on leading a meaningful adult life.B. To stress the need of shouldering responsibilities at work.C. To state the importance of generating motivation for learning.D. To suggest a way of pursuing excellence in our lifelong career.6. 【2019·江苏卷，C】Who cares if people think wrongly that the Internet has had more important influences than the washing machine? Why does it matter that people are more impressed by the most recent changes?It would not matter if these misjudgments were just a matter of people's opinions. However, they have real impacts, as they result in misguided use of scarce resources.The fascination with the ICT(Information and Communication Technology) revolution, represented by the Internet, has made some rich countries wrongly conclude that making things is so "yesterday" that they should try to live on ideas. This belief in "post-industrial society" has led those countries to neglect their manufacturing sector(制造业) with negative consequences for their economies.Even more worryingly, the fascination with the Internet by people in rich countries has moved the international community to worry about the "digital divide" between the rich countries and the poor countries. This has led companies and individuals to donate money to developing countries to buy computer equipment and Internet facilities. The question, however, is whether this is what the developing countries need the most. Perhaps giving money for those less fashionable things such as digging wells, extending electricity networks and making more affordable washing machines would have improved people's lives more than giving every child a laptop computer or setting up Internet centres in rural villages, I am not saying that those things are necessarily more important, but many donators have rushed into fancy programmes without carefully assessing the relative long-term costs and benefits of alternative uses of their money.In yet another example, a fascination with the new has led people to believe that the recent changes in the technologies of communications and transportation are so revolutionary that now we live in a "borderless world". As a result, in the last twenty years or so, many people have come to believe that whatever change is happening today is the result of great technological progress, going against which will be like trying to turn the clock back. Believing in such a world, many governments have put an end to some of the very necessary regulations oncross-border flows of capital, labour and goods, with poor results.Understanding technological trends is very important for correctly designing economic policies, both at the。

（2019年新课标全国卷Ⅱ）【全球气候变暖】近年来，位于高纬的西伯利亚地区气候发生了明显变化，土地覆被也随之变化，平地上的耕地明显减少，洼地上的草地大量转化为湿地，越年积雪（积雪期超过一年）面积减少。

据此完成6～8题。

6．导致西伯利亚地区土地覆被变化的首要原因是A．气温升高B．气温降低C．降水增多D．降水减少7．湿地面积增加主要是因为当地A．洪水暴涨B．退耕还湿C．地面沉降D．冻土融化8．西伯利亚地区平地上减少的耕地主要转化为A．林地B．湿地C．草地D．寒漠【答案】6．A 7．D 8．C【解析】本组题以高纬的西伯利亚地区气候的明显变化，土地覆被也随之变化为背景，考查影响区域植被变化的因素，气候变暖的影响。

6．读材料可知，越年积雪（积雪期超过一年）面积减少，说明积雪融化增多，故首要原因是气温升高，A正确，B错误；降水增多会使越年积雪面积增大，C错误；降水减少，气候趋于干旱，不利于洼地上的草地大量转化为湿地，D错误。

故选A。

7．由上题分析可知，气温升高会导致冻土融化，地表积水增多，湿地面积增加，D正确；材料中“洼地上的草地大量转化为湿地”说明湿地增加的主要原因不是洪水暴涨、退耕还湿和地面沉降引起，ABC错误。

故选D。

8．由上面两题分析可知，气候变暖使冻土融化，地表水增多，但平地较洼地地势高，积水较少，不会有大量的浅水出露地表，减少的耕地不会转化为湿地，地表水分增加，适合草类植被生长，故主要转化为草地，B错误，C正确；题干中“高纬的西伯利亚地区”热量不足，难以形成林地植被，A错误；气候上升使冻土融化，地表水分增多，会使植被覆盖增多，不会转化为寒漠，D错误。
