山西省太原市第五中学2020届高三上学期阶段性检测(10月月考)英语试卷含答案
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. 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。

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 you ng 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 co nsidering 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高三英语 第5页 (共12页) 高三英语 第6页 (共12页)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。
