山西太原五中2020届高三上学期阶段性检测

山西太原五中2020届高三上学期阶段性检测山西太原五中2020届高三上学期阶段性检测一、现代文阅读（36分）（一）论述类文本阅读（本题共3小题，9分）阅读下面文字，完成1～3题。

中国绘画发展到了相对成熟的北宋以后，除了民间画家、宫廷画家等创作群体外，还出现了诗人、士大夫等各类文化人参与创作的现象。

他们以自身文化人的气质，崇尚和追求唐代诗人兼画家王维作品中所蕴含的“诗中有画，画中有诗”的艺术境界。

在绘画创作中，他们以诗人的思考方式，把表现对象提升到诗的艺术境界，创作了很多为后人惯称的“文人画”。

诗人的思考方式，实际上就是中国文人画家基于中国传统画论中东晋大画家顾恺之所言的“迁想妙得”，及后来唐代画家张璪所言的“外师造化，中得心源”的绘画理论，将表现的对象在心中“迁想”成诗的艺术形象的思维过程。

中国文人画家的这种诗人的思考方式，是大文化学养背景下成就的结果。

诗人和音乐家一样，在感情世界里是最敏感的人群，他们所创作的文人画相较西方画家以科学家的思考方式所表现的科学的艺术形象而言，更接近感情的本质，也更显得纯洁与透明。

中国的文人画家在具体创作中，以顾恺之提出的“传神”的艺术理念为要求，以追求作品的出神入化为最终目的。

如宋代画家梁楷所画的《布袋和尚图》和《泼墨仙人图》，以两种粗细不同的艺术手段，表现诙谐而玩世不恭的人物形象。

另外，中国文人画家又以诗人的拟人化手段将表现的对象人格化。

如明代画家徐渭在《墨葡萄图》中所表现的“笔底明珠无卖处，闲抛闲掷野藤中”。

基于大文化学养背景的文人画家创作的文人画，在具体的画面处理中，比单纯追求形象与色彩变化的西方绘画艺术显得更有广度和深度。

他们不仅追求表现对象的“实”处，还以太极中“阴阳”的理念追求其相对“虚”的空间；进而提出了“计白当黑”的画论，将表现的形象延伸到一个更大的审美空间，达到了“此时无声胜有声”的诗意境界。

如八大山人的《鱼鸭图卷》、齐白石的《雏鸡》等作品。

中国的文人画家以大文化学养背景铸就了“心旷神怡、超然物外”的冲淡平和的心态，所以在作品中容易叙述心灵的情怀。

密学校班级姓名学号密封线内不得答题太原五中2019—2020学年度第一学期阶段性检测高三英语(2019.10.9)第一部分阅读理解（共两节，满分60分）第一节（共15小题；每小题3分，满分45分）(A)Many of us know about Russia ’s Lake Baikal from our textbooks, or by listening to Chinese singer Li Jian’s hit song, Lake Baikal. But over the past decade, the world’s deepest freshwater lake has been in the spotlight for an extreme sport.Each March since 2005, about 150 people from around the world sign up for the Baikal Ice Marathon . They come to explore the lake’s breathtaking beauty and challenge themselves in unpredictable conditions.The 26-mile (41. 84-kilometers) journey starts on the lake’s eastern shore. In March, the ice is a meter thick and iron-hard. Runners cross this frozen surface, finishing on the western side of the lake.Known as the “blue eye of Siberia ”, Lake Baikal has exceptionally clear waters. This means its ice is almost perfectly transparent. “Seen from above, a runner on the ice looks as if he or she is jogging through space,” The New York Times noted.Th e landscape might be beautiful, but it’s also harsh. Strong winds blast (侵袭) across the lake and frostbite (冻伤) can occur within half an hour. Runners say the cold climate is what draws them. They want to test their limits.“When you are in such an environment, you don’t have cars around you, you don’t have the noise around. I think these extreme races allow you to be alone with nature,” Alicja Barahona, a 64-year-old runner from the US, told ABC News.The location offers some strange and unique characteristics for this marathon. The finish line is visible from the start. But the endless white offers no progress markers. The race also ends with little fanfare (喧闹). Tourists crowding the ice are mostly addicted to snapping series (自拍) and just ignore the runners.For some runners, the absence of spectators makes the ra ce more challenging, because it’s lonely. They must fight with themselves. “You are alone on Bai kal. It is your race. You are alone with yourself. All you need to do is to defeat yourself,” Veronique Messina, a French runner, told the Telegraph.1. What can we know about the Baikal Ice Marathon from the text?A. It takes runners from the northern end to the southern end of the lake.B. It involves extreme weather and beautiful scenery.C. It attracts more and more participants each year.D. It is about 26 kilometers in length.2. How does the Baikal Ice Marathon differ from other marathons? A. Only men are allowed to run in this race.B. The runners can see the finish line from the start.C. The runners are often distracted by tourists.D. There are many progress markers on the ice.3. What is the most difficult part of the race for Messina? A. Loneliness. B. The long distance. C. The cold climate. D. Noisy surroundings.(B)In 1972, a social worker named Sanjit Bunker Roy founded Barefoot College in Tilonia, Rajasthan. Today the college trains women from villages for six months to build and maintain solar panels and other instruments. Barefoot College also offers education to the younger generation both during the day and at its solar bridge schools that meet by lamplight at night.The philosophy of Barefoot College is largely inspired by the principles of Gandhi, starting with equality beyond caste (种姓), gender or religion. As a matter of fact, women are prioritized (优先考虑) as an underserved population that is essential to bringing villages together. Another central principle of the college is self-reliance, teaching students to support and think for themselves.After the college’s female students have completed their half-year of training, they return to their villages where they wait for solar panel parts to arrive from the college. Once they have all the pieces they need, they construct the panels and begin collecting solar energy. For each village, the college also provides solar lamps. Villagers can, in addition, order parts for other solar-powered devices, such as water heaters and cooking stoves. Once assembled, they and the lamps are powered by the solar panels.The effect on the villages is huge. Before the solar panels and lamps arrived, villagers had only candles to light their homes. This prevented adults from doing serious work at night, and it made studying difficult for children as well. As for physicians, they had difficulty treating patients and performing operations at night because they had to rely on flashlights.Now there is power for not only the electrical appliances that the college provides but also devices like televisions, radios and computers. For the first time, the villagers can even connect to the world through the Internet.密封线内不得答题4. What does this text explain about the college? A. How it accomplishes its goals. B. How its global efforts are funded. C. How its founder hires employees. D. How it works with the government.5. Which idea is communicated by the college to women? A. They should be more involved in politics. B. They don’t have to depend on others .C. They aren’t educating their daughters enough .D. They focus too much on their communities.6. Which role do the women play after they return to their villages? A. They’re merchants . B. They’re composers . C. They’re technicians . D. They’re journalists .7. In the past, what was hard to provide in villages after dark? A. Dry shelter B. Clean water C. Medical care D. Food supplies(C)Imagine you are opening your own company and want to hire a manager. You have two candidates and they are both capable and experienced, so who would you rather hire: Julia Watson or Shobha Bhattacharva? Chances are that you would prefer Watson, right? But why? “Easy names are evaluated as more familiar, less risky and less dangerous, ” Eryn Newman, a scientist at Victoria University of Wellington, New Zealand, told Scientific American. As a result, people with easier names are often assumed to be more trustworthy. This is what Newman and her teammates have found in their recent study.In the experiment, they picked 18 different foreign names, including difficult-to-pronounce ones like Yevgeni Dherzhinsky and easy names like Bodo Wallmeyer. They then attached each name with a statement such as “turtles are deaf” and “giraffes are the only mammals that cannot jump” and asked volunteers whether they thought the claims were true.The results showed that claims connected to easier names were more often ranked as believable than those attributed to difficult names, regardless of what the truth really was. In fact, previous studies have already found that our judgments about products can be affected by their names. For example, we tend to think of a food additive (添加剂) with an easier name as safer and a stock with an easier name as more lucrative (利润丰厚的)，according to Medical Daily.But researchers pointed out that this effect can change depending on where someone comes from. For example, a native British ma n may find “Yevgeni Dherzhinsky” hard to pronounce while Russian people could say it without effort. Newman hopes that this finding can make us better see our biases (偏见). It’s not just unfair to people that we make judgments based on gut feelings (直觉) rather than facts, and it can sometimes have serious consequences.For example, we may choose to believe certain eyewitnesses in court simply because their names sound more trustworthy even if they are actually lying. Or, we may let go of qualified job candidates due to their “difficult” names.Now, if you could make that decision again, would you still prefer Julia Watson to Shobha Bhattacharva?8. What did Newman and her teammates discover in their experiment? A. Volunteers with easier names were more likely to choose true claims.B. A difficult name doesn’t influence the way the volunteers viewed the claims.C. V olunteers trusted claims paired with easy names more often.D. V olunteers trusted claims connected with difficult names.9. The underlined w ords “this effect” in Paragraph 5 refer to the effect ______. A. names have on peoples judgmentsB. gut feelings have on people from different placesC. of decisions made based on factsD. of people ’s biases against certain types of people 10. What can we conclude from the last paragraph?A. We should think twice before we make a decision.B. The harder your name is to pronounce, the more likely it is you will get a job.C. Judging people based on their names may cause serious problems.D. Russian s have less bias against people’s names than the British. 11. What is probably the best title for the text? A. Names Affect ProductsB. Employers Prefer Shobha BhattacharvaC. Difficult Names are TrustworthyD. Easy Names Win Out(D)Many of us have had this experience: we lie down in a bed other than our own, perhaps at a friend’s house or in a hotel room, and find it difficult or impossible to fall asleep. Is it because the bed is uncomfortable? Maybe, but perhaps there can be other reasons.According to a new study published in Current Biology, a significant reason is what the scientists call “first night effect”. They believe that one side of the brain acts as a “night watch” to warn us about potential dangers. It forces us to stay awake on the first night in a new environment. For the study, 35 young volunteers were asked to sleep in a sleep lab for several days. Meanwhile, researchers watched their brain activities.密学校班级姓名学号密封线内不得答题According to the researchers, on their first night, the left brains were more active than the right brains and people had a hard time sleeping. However, left-brain activity decreased as days went by, falling even to the point of complete calm. In this process, the participants got an increasingly better sleep experience.The findings suggest that the different rhythms (5%) of the sides of the brain affect our sleep. When the two sides work differently, the balance between them is broken. Thus, the brain can’t relax and is sensitive to anything strange in the surroundings, just as it is in daytime.“At some level, the brain is continuing to analyze things, even though you are not aware of the ana lysis, ” US professor Jerome Siegel told Smithsonian Magazine. “If something unusual happens --- if a door opens or you hear a key in a lock--- you can be alert, even though the intensity of the stimulus (刺激) is quite low.”More surprisingly, this phenomenon is similar to the way some animals sleep. Whales, dolphins, and many birds can sleep with half of their brain while the other half stays awake, with its corresponding eye staying open.The researchers think that it is the result of evolution, and works to protect us in potentially dangerous environments.If you have ever had what you think is “first night effect”, researchers suggest that you bring your own pillow or sleep in a room similar to your bedroom next time you sleep away from home.12. What did the new study published in Current Biology find?A. A comfortable bed could help people sleep well in a new environment.B. Most people could sleep well in a new environment after the first night.C. Brain activities affected people ’s sleep in a new environment.D. The right brain determined how well people slept in a new environment. 13. What was found out about the volunteers?A. Their left brains were more active on the first night.B. Their right brains became more active as days went by.C. Their right brains kept them awake the whole night.D. They slept better in the sleep lab than at home.14. What do the researchers think makes the brain sensitive to new things? A. The bad sleep experiences people have had. B. The tiredness that people suffer from in daytime. C. The imbalance between the two sides of the brain. D. The strangeness of the things that people come across 15. What do the researchers think of “first night effect” ? A. It has evolved as a way to protect us.B. It’s a characteristic that animals don’t have.C. It’s completely different from the way animals sleep.D. It helps people to get used to new environments quickly.第二节（共5小题；每小题3分，满分15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。

太原五中2019—2020学年度第一学期阶段性检测高三英语出题人、校题人：史海玲荆晋慧张旭军王轶芳郝媛(2019.10.9)第一部分阅读理解（共两节，满分60分）第一节（共15小题；每小题3分，满分45分）(A)Many of us know about Russia’s Lake Baikal from our textbooks, or by listening to Chinese singer Li Jian’s hit song, Lake Baikal. But over the past decade, the world’s deepest freshwater lake has been in the spotlight for an extreme sport.Each March since 2005, about 150 people from around the world sign up for the Baikal Ice Marathon. They come to explore the lake’s breathtaking beauty and challenge themselves in unpredictable conditions.The 26-mile (41. 84-kilometers) journey starts on the lake’s eastern shore. In March, the ice is a meter thick and iron-hard. Runners cross this frozen surface, finishing on the western side of the lake.Known as the “blue eye of Siberia”, Lake Baikal has exceptionally clear waters. This means its ice is almost perfectly transparent. “Seen from above, a runner on the ice looks as if he or she is jogging through space,” The New York Times noted.Th e landscape might be beautiful, but it’s also harsh. Strong winds blast (侵袭) across the lake and frostbite (冻伤) can occur within half an hour. Runners say the cold climate is what draws them. They want to test their limits.“When you are in such an environment, you don’t have cars around you, you don’t have the noise around. I think these extreme races allow you to be alone with nature,”Alicja Barahona, a 64-year-old runner from the US, told ABC News.The location offers some strange and unique characteristics for this marathon. The finish line is visible from the start. But the endless white offers no progress markers. The race also ends with little fanfare (喧闹). Tourists crowding the ice are mostly addicted to snapping series (自拍) and just ignore the runners.For some runners, the absence of spectators makes the ra ce more challenging, because it’s lonely. They must fight with themselves. “You are alone on Bai kal. It is your race. You are alone with yourself. All you need to do is to defeat yourself,” Veronique Messina, a French runner, told the Telegraph.1. What can we know about the Baikal Ice Marathon from the text?A. It takes runners from the northern end to the southern end of the lake.B. It involves extreme weather and beautiful scenery.C. It attracts more and more participants each year.D. It is about 26 kilometers in length.2. How does the Baikal Ice Marathon differ from other marathons?A. Only men are allowed to run in this race.B. The runners can see the finish line from the start.C. The runners are often distracted by tourists.D. There are many progress markers on the ice.3. What is the most difficult part of the race for Messina?A. Loneliness.B. The long distance.C. The cold climate.D. Noisy surroundings.(B)In 1972, a social worker named Sanjit Bunker Roy founded Barefoot College in Tilonia, Rajasthan. Today the college trains women from villages for six months to build and maintain solar panels and other instruments. Barefoot College also offers education to the younger generation both during the day and at its solar bridge schools that meet by lamplight at night.The philosophy of Barefoot College is largely inspired by the principles of Gandhi, starting with equality beyond caste (种姓), gender or religion. As a matter of fact, women are prioritized (优先考虑) as an underserved population that is essential to bringing villages together. Another central principle of the college is self-reliance, teaching students to support and think for themselves.After the college’s female students have completed their half-year of training, they return to their villages where they wait for solar panel parts to arrive from the college. Once they have all the pieces they need, they construct the panels and begin collecting solar energy. For each village, the college also provides solar lamps. Villagers can, in addition, order parts for other solar-powered devices, such as water heaters and cooking stoves. Once assembled, they and the lamps are powered by the solar panels.The effect on the villages is huge. Before the solar panels and lamps arrived, villagers had only candles to light their homes. This prevented adults from doing serious work at night, and it made studying difficult for children as well. As for physicians, they had difficulty treating patients and performing operations at night because they had to rely on flashlights.Now there is power for not only the electrical appliances that the college provides but also devices like televisions, radios and computers. For the first time, the villagers can even connect to the world through the Internet.4. What does this text explain about the college?A. How it accomplishes its goals.B. How its global efforts are funded.C. How its founder hires employees.D. How it works with the government.5. Which idea is communicated by the college to women?A. They should be more involved in politics.B. They don’t have to depend on others.C. They aren’t educating their daughters enough.D. They focus too much on their communities.6. Which role do the women play after they return to their villages?A. They’re merchants.B. They’re composers.C. They’re technicians.D. They’re journalists.7. In the past, what was hard to provide in villages after dark?A. Dry shelterB. Clean waterC. Medical careD. Food supplies(C)高三英语第3页(共22页)高三英语第4页(共22页)Imagine you are opening your own company and want to hire a manager. You have two candidates and they are both capable and experienced, so who would you rather hire: Julia Watson or Shobha Bhattacharva? Chances are that you would prefer Watson, right? But why?“Easy names are evaluated as more familiar, less risky and less dangerous, ” Eryn Newman, a scientist at Victoria University of Wellington, New Zealand, told Scientific American. As a result, people with easier names are often assumed to be more trustworthy. This is what Newman and her teammates have found in their recent study.In the experiment, they picked 18 different foreign names, including difficult-to-pronounce ones like Yevgeni Dherzhinsky and easy names like Bodo Wallmeyer. They then attached each name with a statement such as “turtles are deaf” and “giraffes are the only mammals that cannot jump”and asked volunteers whether they thought the claims were true.The results showed that claims connected to easier names were more often ranked as believable than those attributed to difficult names, regardless of what the truth really was. In fact, previous studies have already found that our judgments about products can be affected by their names. For example, we tend to think of a food additive (添加剂) with an easier name as safer and a stock with an easier name as more lucrative (利润丰厚的)，according to Medical Daily.But researchers pointed out that this effect can change depending on where someone comes from. For example, a native British ma n may find “Yevgeni Dherzhinsky” hard to pronounce while Russian people could say it without effort. Newman hopes that this finding can make us better see our biases (偏见). It’s not just unfair to people that we make judgments based on gut feelings (直觉) rather than facts, and it can sometimes have serious consequences.For example, we may choose to believe certain eyewitnesses in court simply because their names sound more trustworthy even if they are actually lying. Or, we may let go of qualified job candidates due to their “difficult” names.Now, if you could make that decision again, would you still prefer Julia Watson to Shobha Bhattacharva?8. What did Newman and her teammates discover in their experiment?A. V olunteers with easier names were more likely to choose true claims.B. A difficult name doesn’t influence the way the volunteers viewed the claims.C. V olunteers trusted claims paired with easy names more often.D. Volunteers trusted claims connected with difficult names.9. The underlined w ords “this effect” in Paragraph 5 refer to the effect ______.A. names have on peoples judgmentsB. gut feelings have on people from different placesC. of decisions made based on factsD. of people’s biases against certain types of people10. What can we conclude from the last paragraph?A. We should think twice before we make a decision.B. The harder your name is to pronounce, the more likely it is you will get a job.C. Judging people based on their names may cause serious problems.D. Russian s have less bias against people’s names than the British.11. What is probably the best title for the text?A. Names Affect ProductsB. Employers Prefer Shobha BhattacharvaC. Difficult Names are TrustworthyD. Easy Names Win Out(D)Many of us have had this experience: we lie down in a bed other than our own, perhaps at a friend’s house or in a hotel room, and find it difficult or impossible to fall asleep. Is it because the bed is uncomfortable? Maybe, but perhaps there can be other reasons.According to a new study published in Current Biology, a significant reason is what the scientists call “first night effect”. They believe that one side of the brain acts as a “night watch”to warn us about potential dangers. It forces us to stay awake on the first night in a new environment. For the study, 35 young volunteers were asked to sleep in a sleep lab for several days. Meanwhile, researchers watched their brain activities.According to the researchers, on their first night, the left brains were more active than the right brains and people had a hard time sleeping. However, left-brain activity decreased as days went by, falling even to the point of complete calm. In this process, the participants got an increasingly better sleep experience.The findings suggest that the different rhythms (5%) of the sides of the brain affect our sleep. When the two sides work differently, the balance between them is broken. Thus, the brain can’t relax and is sensitive to anything strange in the surroundings, just as it is in daytime.“At some level, the brain is continuing to analyze things, even though you are not aware of the ana lysis, ”US professor Jerome Siegel told Smithsonian Magazine. “If something unusual happens --- if a door opens or you hear a key in a lock--- you can be alert, even though the intensity of the stimulus (刺激) is quite low.”More surprisingly, this phenomenon is similar to the way some animals sleep. Whales, dolphins, and many birds can sleep with half of their brain while the other half stays awake, with its corresponding eye staying open.The researchers think that it is the result of evolution, and works to protect us in potentially dangerous environments.If you have ever had what you think is “first night effect”, researchers suggest that you bring your own pillow or sleep in a room similar to your bedroom next time you sleep away from home.12. What did the new study published in Current Biology find?A. A comfortable bed could help people sleep well in a new environment.B. Most people could sleep well in a new environment after the first night.C. Brain activities affected people’s sleep in a new environment.D. The right brain determined how well people slept in a new environment.13. What was found out about the volunteers?A. Their left brains were more active on the first night.B. Their right brains became more active as days went by.C. Their right brains kept them awake the whole night.D. They slept better in the sleep lab than at home.14. What do the researchers think makes the brain sensitive to new things?A. The bad sleep experiences people have had.B. The tiredness that people suffer from in daytime.C. The imbalance between the two sides of the brain.D. The strangeness of the things that people come across高三英语第7页(共22页)高三英语第8页(共22页)15. What do the researchers think of “first night effect” ?A. It has evolved as a way to protect us.B. It’s a characteristic that animals don’t have.C. It’s completely different from the way animals sleep.D.

作为巫书的《山海经》，其内容是由古代巫师若干世纪的承传附益积累，再由不同时期巫师群中的不同作者（可能还有才士文人参与其事）将它们笔之于书而成就起来的。

古代的巫师，实际上就是古代的知识分子，一切文化知识都要通过巫师的手进行传播。

因而在这部书里，除神话传说外，还涉及地理、历史、宗教、民俗、历象、动物、植物、矿物、医药、人类学、民族学、地质学、海洋学等等，这真可以说是一部奇书，一部古代人们生活日用的百科全书，虽然只有三万一千多字。

为什么以神话为主的一部巫书竟会包括那么多学科？因为这正是原始时代原始先民通过神话思维刻印下来的痕迹。

所有探讨认识的一切，都蒙上神话或宗教的色彩。

有些探讨认识，仍是比较正确的，那就成了科学的萌芽，给我们提供了很高的认识价值和研究价值。

原始社会母权制时期的神话，有《大荒西经》所记的女娲之肠化为十神的神话。

Which of the following skills takes the longest time for each lesson? A. Foreign languages. B. Life hacks. C. Health & Fitness. D. Technology.2. Which website can tell you how to work more effectively?A. Skillshare.B. Hackaday.C. 7-min.D. Big Think. 3. Which is true about the websites mentioned in the text? A. They are free. B. They are expensive. C. They are instructive. D.They are meant for students.BRecently, I noticed that my three-year-old daughter Ula had difficulty seeing the pictures in her books. We took her to a doctor, and an hour later, I was told that she needed glasses.Ula disagreed. The first pair had various pieces broken off them in less than a week, and subsequent (随后的) pairs went missing or were broken.Ula needs glasses. With them, she can find food with her fork, put together puzzles, and enjoy her books. However, I am convinced that Ula came into our family with the purpose of teaching us the meaning of free will.I received a letter from my friend recently that really drove this point home.Marie and her husband both chose to give up their conventional careers, raising their daughters with no electrical items except lights and a radio. They managed to raise their family on a very low income, making ends meet through part-time work.Both daughters were home-schooled, and completed college through distance learning programs.Now ready to make her own path in life, the eldest, Angelica, is armed with many skills and grew up learning how to live on very little.She found a boyfriend, and as the relationship progressed, the couple decided to move in together. Eventually, Angelica began questioning the value of her unique lifestyle, and then the youn g man urged her to “get a real job”.Fully aware that similar struggles might lie in Ula’s future, I shared my friend’s worry in wondering what her daughter would do.We all try to raise our children with the skills to require little from others, and to honor their heart, relationships, and creativity.But as Ula has taught me, there’s little we can do if our kids refuse our guidance. Wemust know that we’ve shown our children that they don’t have to choose the same path as everyone else. We must know in our hearts that we have lived our ideals, which we have demonstrated is possible in a way that is true to our souls. The rest is up to them.And that seems to have worked in Marie’s case. Just before moving in with her boyfriend, Angelica spent two weeks con sidering his “get a real job” suggestion. Then she ended the relationship.4.What can we learn from the first three paragraphs?A.Ula didn’t feel like wearing glasses.B.Ula enjoyed playing with her glasses.C.The author has learned the significance of freedom.D.The author got angry when Ula damaged her glasses.5.How was Angelica brought up?A.She grew up in a rich family.B.Her parents were strict with her.C.Her parents taught her how to live a simple life.D.She was expected to take a conventional job.6.Angelica broke up with her boyfriend probably because_________.A.her parents strongly advised her toB.they had different education experiencesC.she was dissatisfied with his life skillsD.she preferred to stick to her own lifestyle7.The author wrote this article mainly to ________.A.tell parents that they should respect their kids’ free willB.explore ways to deal with kids refusing guidanceC.show that the way one is raised has strong effectsD.encourage people to take different paths from othersCHave you ever said to a friend “That rose’s scent is really sweet!”, only to find that your friend can’t smell anything at all?According to a study published in the journal PNAS in May, people have different abilities to detect certain odors (气味) —and it is linked to different genes.For the study, 300 people were placed among 150 jars with different odors. At a given time, they had to smell an odor and then rate the intensity and pleasantness of the odor on a scale from 1 (extremely weak / unpleasant) to 7 (extremely strong / pleasant). Before they left, the participants needed to leave a blood sample.After comparing genes of the participants, researchers found all had different smelling abilities and that the differences between these abilities could be traced to certain genes.According to The New York Times, human beings have nearly 400 genes that directly control olfactory (嗅觉的) receptor (受体) and influence the way these receptor become active.“Odors... turn on specific detectors, and this pattern of activation (触发) tells us if we are smelling a flower, how strong we find it, and whether we like it,” said Casey Trimmer, a geneticist and the lead author of the study. “One small change in the gene for the receptor can change its shape and how well the odor fits, thereby changing perception of the odor.”Though genes play a crucial role in our ability to smell, other factors, including interest, past associations and expectations, are important as well. For example, if we love the scent of roses, we are drawn to their scent and pay special attention to it.But what does our different abilities to detect odors mean?“Olfaction is the most important sense for the rest of the animal kingdom,”said Trimmer. Although, unlike other animals, humans aren’t any longer dependent on their sense of smell to find food or detect danger, smell is still a significant sense. There is also evidence that a reduced sense of smell is an early symptom of Alzheimer’s disease.8.What did the study find about smelling?A.Men and women have different smelling abilities.B.Differences between smelling abilities lie in the genes.C.Human beings can tell 150 odors apart.D.People’s abilities to smell change over time.9.What is Trimmer’s message?A.Our receptors turn off when we smell an unpleasant smell.B.People’s preferences for smells can affect their health.C.Small changes in the gene for smelling can make a big difference.D.The sense of smell is the most important human sense.10.According to the text, which might influence our smelling abilities?a. other sensesb. the environmentc. past experiencesd. attentionA.abB. bcC. bdD. cd11.What can we learn from the last paragraph?A.Human beings have a better sense of smell than other animals.B.Smell is still an important sense in detecting danger.C.The loss of sense of smell causes many health problems.D.Poor smelling ability may be an early sign of some disease.D密学校班级姓名学号密封线内不得答题First the robots came for our jobs. Now they are coming for our hobbies. Google ’s DeepMind AI lab has been busy in the past few years, creating programs to take on human players across a variety of games. In 2016 its AIphaGo beat the best of Go player in the world. Earlier this year, its Alpha Star defeated two middle-tier players at the popular online game StarCraft II. Now it is learning to win at multi-player games.“Artificially intelligent agents are getting better and better at two-player games, but most real-world endeavors require teamwork,” DeepMind ’s researchers wrote in a paper published in Science in June.To be sure, computers have been proving their dominance over humans in one-on-one turn-based games such as chess ever since IBM ’s Deep Blue beat Russian chess master Garry Kasparov in 1997.However, successfully using teamwork to win in multi-player games with complex environments was difficult to achieve.For this purpose, DeepMind ’s researchers designed AI agents that taught themselves how to play first-person game Quake III Arena. The team, led by Max Jaderberg, worked on a modified version of Quake III Arena.The game mode they chose was “Capture (抢) the Flag ”. All the players must work together to steal the other team ’s flag while safeguarding their own.The AI agents “trained ” with 12 hours of game data, and then matched up against professional game testers. The programmers used various kinds of “rewards ” to help the AI players weigh their goals and actions to help them cooperate in the teamwork. They also used randomized maps for each new match. The AI won 75 percent of the time, even when its reaction time artificially slowed down to human levels and when their aiming ability was similarly reduced.“That means the solutions that the agents find have to be general —they cannot just memorize a sequence of actions,” said co-author Wojciech Czarnecki.The only time humans were able to beat AI agents was when they teamed up together. A team consisting of one human and one AI agent had a five percent greater win probability than a team of just AI agents.Ethan Gach said at the video game news website Kotaku, “It suggests that the AI program is able to well adapt to playing with non-AI teammates.” In the near future, AI may cooperate with human beings in some other fields, such as medicine and other branches of science.12. What might be the tough task for AI agents in multi-player games? A. Understanding the rules.B. Cooperating with other players.C. Memorizing complex actions.D. Increasing reaction speed.13. What does the underlined word “dominance ” in Paragraph 3 mean?A. Balance.B. Adaptation.C. Control.D. Advantage. 14. How did the researchers of Google ’s DeepMind train AI agents? A. They gave various “punishments ” when AI agents lost the games. B. They made AI agents team up with amateur human players. C. They limited the time for AI agents to complete difficult tasks. D. They put them through different games with various tasks. 15. What can we infer from the passage?A. AI players perform better than humans in a team game.B. AI programs should be offered more game data.C. AI program is able to do well with human players.D. AI programs have been successfully applied in the field of medicine.第二节（共5小题；每小题3分，满分15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。

中国绘画发展到了相对成熟的北宋以后，除了民间画家、宫廷画家等创作群体外，还出现了诗人、士大夫等各类文化人参与创作的现象。

他们以自身文化人的气质，崇尚和追求唐代诗人兼画家王维作品中所蕴含的“诗中有画，画中有诗”的艺术境界。

在绘画创作中，他们以诗人的思考方式，把表现对象提升到诗的艺术境界，创作了很多为后人惯称的“文人画”。

中国文人画家的这种诗人的思考方式，是大文化学养背景下成就的结果。

中国的文人画家在具体创作中，以顾恺之提出的“传神”的艺术理念为要求，以追求作品的出神入化为最终目的。

如宋代画家梁楷所画的《布袋和尚图》和《泼墨仙人图》，以两种粗细不同的艺术手段，表现诙谐而玩世不恭的人物形象。

另外，中国文人画家又以诗人的拟人化手段将表现的对象人格化。

如明代画家徐渭在《墨葡萄图》中所表现的“笔底明珠无卖处，闲抛闲掷野藤中”。

基于大文化学养背景的文人画家创作的文人画，在具体的画面处理中，比单纯追求形象与色彩变化的西方绘画艺术显得更有广度和深度。

如八大山人的《鱼鸭图卷》、齐白石的《雏鸡》等作品。

中国的文人画家以大文化学养背景铸就了“心旷神怡、超然物外”的冲淡平和的心态，所以在作品中容易叙述心灵的情怀。

如宋代米友仁的《潇湘奇观图》表现的“山色空蒙雨亦奇”的境界，元代画家吴镇的《渔父图卷》表现的“斜风细雨不须归”的超然境界。

中国的文人画家在诗、文、书法等各方面的学养上往往都有很高的造诣。

中国文人画，那种集诗、书、画于一体的绘画形式，在世界绘画史上是绝无仅有的。

文人画不但是中国古代文明在绘画中的综合体现，而且是世界绘画史皇冠上的明珠。

这些传世优秀的文人画作品，足以与晋唐的书法及唐诗宋词，共同构成中国文化史上三大具有代表性的板块。

（二）实用类文本阅读（本题共3小题，12分）阅读下面的文字，完成4～6题。

材料一：“双元制”是一种国家立法支持、校企合作共建的办学制度。

所谓“双元”，是指职业培训要求参加培训的人员必须经过两个场所的培训。

“一元”是指职业学校，其主要职能是传授与职业有关的专业知识；“另一元”是指企业或公共事业单位等校外实训场所，其主要职能是让学生在企业里接受职业技能方面的专业培训。

“双元制”职业教育不同于一般的大学教育。

大学教育重视理论学习，是学科体系，而“双元制”职业教育以岗位要求为培训目标，更加重视学生的实践能力。

这种侧重实践的教育形式非常受欢迎，很多年轻人选择“双元制”教育培训，而不是去上大学。

“双元制”教学体制使得学生和企业有了更多的交流机会，大大提高了学生培训后就业的能力，有利于为劳动市场输送大量合格的劳动力。

（摘编自网络，有删改）材料二：职业教育主要关注点分布（摘自环球网《大数据透视两会教育热点─2019年全国两会教育热点问题分析报告》）材料三：最近，湖北潜江一所职业教育学院设立了“小龙虾专业”，该专业的学生还没毕业就被“销售一空”，薪酬也着实可观。

细品“小龙虾学院”这道“菜”，不难咂摸出这样的“味道”：接地气、把握市场脉搏的职业教育其实有很广阔的前景。

一直以来，就业市场存在结构矛盾：一边是大学生面临就业难，一边是企业面临招工难、用工荒。

劳动力需求与供给之间“错位”。

这恰恰说明经济社会发展需要大批技术、技能型人才，只有大力发展职业教育，培养大量高素质劳动者和应用型人才，才能从根本上解决这一问题。

近年来，对“工匠精神”的呼唤成为社会共识。

能力是最好的学历，本事是最大的优势。

职业教育的大发展，也需要在劳动观、价值观上进行一场深刻的革命。

消除偏见和误解的坚冰，让广大青年凭一技之长实现人生价值，让各行各业的劳动者都拥有尊严与荣光，创新、创业、创造的无穷活力必然会竞相迸发。

（摘编自《“小龙虾学院”折射职业教育“大前景”》，有删改）材料四：3月15日，2019年全国两会落下帷幕。

今年的政府工作报告提出“改革完善高职院校考试招生办法，鼓励更多人报考”“支持企业和社会力量兴办职业教育”等，这些重要举措迅速抬升了职业教育舆情热度，使之成为今年两会期间教育主题。

两会前，国务院印发《国家职业教育改革实施方案》引发热议。

《方案》指出，从2019年开始，在职业院校、应用型本科高校启动“学历证书+若干职业技能等级证书”制度试点工作。

经过5～10年时间，职业教育基本完成由政府举办为主向政府统筹管理、社会多元办学的格局转变，由参照普通教育办学模式向企业社会参与、专业特色鲜明的类型教育转变，大幅度提升新时代职业教育现代化水平，为促进经济社会发展和提高国家竞争力提供优质人才资源支撑。

《方案》要求，要加强党对职业教育工作的全面领导，做好职业教育改革组织实施和相关保障工作。

提高技术技能人才待遇水平，健全经费投入机制，加强职业教育办学质量督导评价。

（摘编自新华社《国家职业教育改革实施方案》，有删改）4. 下列对材料相关内容的理解，不正确的一项是（3分）A. 与一般的大学教育重视理论学习相比，以岗位要求为培训目标的“双元制”教育模式更加重视学生的实践能力。

B. 职业教育学院设立“小龙虾专业”的事情说明，在经济社会中能够培养应用型人才、把握市场脉搏的专业前景广阔。

D. 今后，我国将大幅提升新时代职业教育现代化水平，职业教育将为促进经济社会发展和提高国家竞争力做出贡献。

5. 下列对材料相关内容的概括和分析，正确的一项是（3分）A. “双元制”教学体制下的学生和企业有更多交流机会，具有更强的就业能力，较其他大学生更受企业欢迎。

B. 从材料二看，职业教育招生制度舆论关注度最高，说明国家对职业教育越来越重视，职业教育前景广阔。

C. 随着人们劳动观、价值观的转变，我国将会有越来越多的年轻人选择职业教育培训，而不是去上大学，市场将越来越重能力而轻学历。

D. 大力发展职业教育，培养大量高素质劳动者和应用型人才，是解决我国就业市场结构性矛盾的根本途径。

6.根据上述材料，谈谈我国为进一步办好新时代职业教育，可采取哪些具体措施。

（6分）（三）文学类文本阅读（本题共3小题，15分）阅读下面的文字，完成7～9题。

断桥蒋寒接连两场暴雨，上百年的古桥，被山洪毁了。

洪水将山寨与外界天各一方，孩子们上学，大人们赶集，只能靠树杆、木梯、竹竿慢慢爬过去了。

村民们找到郭支书，请他拿主意。

郭支书住在山寨对岸的郭家坨，郭家坨地势高，再大的洪水也奈何不了它。

郭支书听了村民的反映，吧嗒着旱烟，思忖着，不急。

乡亲们急啊，挤了他家满满一屋子，支书娘子忙着为大家沏茶添水。

山寨丙成代表大伙说：“就那样断着，不是个事啊！大人进进出出好办，娃娃们上学呢？你不是常说，一切为了下一代嘛！”郭支书伸出两指捻了捻火星闪动的旱烟，吧嗒着，不吭声。

有人小声说：“我们知道，你肯定还在生大伙的气。

入夏以来，见你没少往古桥下跑，东瞅瞅，西敲敲，大伙说你是盼着古桥垮了，好向上面申请救济款，以便从中捞……”声音小得没人听得见。

屋外的大狼狗汪汪地叫了，天空还是阴沉沉的。

天气预报说了，近期还将有持续暴雨，省、市、县层层拉响了防汛警报。

村委会也早作了安排，这会儿，马主任正带着工作队现场走访……丙成说：“郭书记，你大人大量，快替大家拿个主意吧。

上面要不拨款，我们各家凑也行。

”郭支书翻大伙一眼，说：“钱，我来想办法，力，大家得出。

”“要得要得！”大伙就兴高采烈地散了。

有人见，第二天一早，郭支书拎着包朝镇上去了。

几天后回村，他就给望眼欲穿的乡亲们一个天大的喜讯：修桥款弄到了，钢筋水泥什么的都联系好了，接着就送来，天晴就动工……时不我待，趁着阳光天气，两台吊车就轰轰隆隆开进断桥现场，洪水也下降了许多，山寨老少能动的都出来了，大伙说说笑笑，干得热火朝天……郭支书和马主任在现场指挥。

马主任抹了抹烟嘴，递给郭支书，白烟就从郭支书的鼻孔里冒出来，一脸欣慰。

马主任感慨道：“老伙计啊，真是难为你了，镇上县上一毛不拔，得亏你家老大开明啊，从自己公司支持50万。

”郭支书笑：“我们养育下一代图啥，不就是为我们修桥修路修康庄大道嘛。

”马主任向他竖起了大拇指。

半个月之后，一座崭新的现代大桥就牢牢地架在了天河上，连接着山寨与外面的世界。

可是随后，村里传出了关于郭支书的风言风语，说是郭支书这回准是贪了不少上面的修桥款，有人甚至闹着要找郭支书讨工钱。

风言风语被马主任苦口婆心压了下去，大伙听说是郭支书的大儿子公司出的钱，又有话说了，不仗着他老爹是个支书，他能开公司吗？再说，50万啊，没有好处的事情，傻子才干！马主任听了，哭笑不得。
