2019届四川省蓉城名校联盟高三上学期第一次联考文综政治试题（解析版）1.67岁的谢大爷在超市买了8.8元的葡萄，排队付款时，被收银员告知不收现金，只收微信。

谢大爷激动地说：“我拿的是人民币，不是假币。

”对于谢大爷持现金被拒，以下认识正确的是①人民币是国家发行并强制使用的②只有不断学习，才能不落后于时代③移动支付只是支付手段，不是流通货币的替代④移动支付技术的成熟，给消费与交易带来了便利A. ①②B. ①③C. ②③D. ③④【答案】B【解析】【详解】根据题意，谢大爷使用人民币支付商品，但收银员拒绝使用现金，要求使用微信支付。

该收银员混淆了人民币和支付手段的区别，微信支付仅仅是支付手段，不能替代现实中的货币流通，因此③正确；从人民币自身来看，人民币作为法定货币，是国家发行并强制使用的，任何机构和个人不得拒绝，因此该收银员做法也是错误的，①正确。

题意不在于强调人要学习跟上时代发展步伐，排除②；题意强调移动支付对特定群体的不便利的地方，排除④。

故选B。

【点睛】纸币是由国家（或某个地区）发行并强制使用的。

随着信息技术的发展，出现用于支付的“电子货币”，纸币的使用明显减少，但是电子货币并不能代替纸币的发行。

2.依据下图信息，若汇率变动的趋势在2018年继续延续，下列判断正确的是①中国外债压力减小，外汇储备升值②美国企业对中国直接投资成本增加③美国对中国进口增加，中国居民增持美元资产④美国商品在华价格优势显现，国内企业压力加剧A. ①②B. ①③C. ②④D. ③④【答案】C【解析】【详解】图中反映出人民币兑美元汇率走低，意味着人民币升值，美元贬值，1美元兑换的人民币更少。

在此条件下，美国企业对中国直接投资成本增加，有利于美国商品出口到中国，美国商品在华价格降低，对我国企业形成压力，②④符合题意。

人民币升值，美元升值，中国持有的外债用美元表示减少，外债压力减小，外汇储备贬值，①排除；人民币升值，不利于中国商品出口到美国，中国居民减持美元资产，排除③。

四川省蓉城名校联盟2019届高三生物上学期第一次联考试题（含解析）1.下列有关实验的叙述中，正确的是A. 观察洋葱根尖有丝分裂实验中，可观察到染色体向细胞的两极移动B. 花生子叶切片用苏丹Ⅳ染色后，需用清水进行漂洗C. 观察植物细胞质壁分离时可以选择液泡中不含有色素的细胞D. 观察DNA在细胞中的分布时可用健那绿将DNA染成绿色【答案】C【解析】【分析】观察有丝分裂实验中，由于解离作用，细胞已经死亡，故无法观察到动态的生理变化过程。

染色实验中为防止染剂的浮色对实验结果的干扰，常需要洗去浮色，要根据染剂的特性选择合适的漂洗试剂，如脂肪鉴定时需选择50%的酒精洗去浮色。

【详解】观察洋葱根尖有丝分裂实验中，由于经过解离后细胞已经死亡，故不能观察到细胞动态分裂的过程，即看不到染色体向细胞的两极移动的现象，A错误；经苏丹Ⅲ染色后的花生子叶切片需用体积分数为50%的酒精洗去浮色，B错误；植物细胞质壁分离实验一般要选择有颜色的材料，有利于实验现象的观察，若实验材料无色，也可以在外界溶液中加入色素，以便于观察，或调节显微镜的光圈和反光镜使视野变得暗一些，也可以观察到实验现象，C正确；健那绿是给线粒体染色的活体染色剂，而给DNA染色的是甲基绿，给RNA 染色的是吡罗红试剂，D错误。

故选C。

【点睛】本题考查观察DNA和RNA、观察植物细胞的质壁分离和复原、观察细胞的有丝分裂和脂肪鉴定等实验，此类试题，需要考生注意的细节较多，如实验的原理、实验选材、实验采用的试剂及试剂的作用等，需要考生在平时的学习生活中注意积累。

2.细胞的结构与功能存在密切的联系，下列有关叙述正确的是A. 肺炎双球菌细胞中有的酶在核糖体上合成后由内质网加工B. 蓝藻细胞叶绿体产生的 ATP 可用于高尔基体加工蛋白质C. 选择透过性的基础是细胞膜上的载体蛋白和磷脂分子具有特异性D. 溶酶体有多种水解酶，溶酶体膜破裂后会造成细胞结构的破坏【答案】D【解析】【分析】原核细胞只有核糖体一种细胞器，光反应产生的ATP只用于暗反应。

绝密★启用前四川省蓉城名校联盟2019届高三上学期第一次大联考理综-化学试题（解析版）1.下列有关化学在日常生活中的应用，说法正确的是A. 生活中常用于消毒的酒精属于纯净物B. 厨房里用食醋去水垢发生了氧化还原反应C. 用热的纯碱溶液和用蒸馏汽油去油污均是化学变化D. 炒菜所用铁锅出现红色的锈斑发生了电化学腐蚀【答案】D【解析】【详解】A. 生活中常用于消毒的酒精是酒精的水溶液，属于混合物，故A错误；B. 厨房里用食醋去水垢是复分解反应，故B错误；C. 用热的纯碱溶液去油污是发生水解反应，运用化学变化；用蒸馏汽油去油污是利用了相似相溶原理，属于物理变化，故C错误；D. 生活中的金属腐蚀多数是电化学腐蚀，炒菜所用铁锅出现红色的锈斑也主要发生了电化学腐蚀，故D正确。

故选D。

2.N A表示阿伏加德罗常数，下列说法正确的是A. 162g 淀粉和纤维素混合物中氧原子的数目为 5N AB. 常温时， pH=5 的盐酸中水电离的 OH－数目为 10－9N AC. 5mol 的 CH3COONa 固体溶于水所得溶液中 CH3COO－数目为 5N AD. 22.4LCl2与足量的铁反应，转移的电子数目为 2N A【答案】A【解析】【详解】A. 淀粉和纤维素的分子式书写相同：（C6H10O5）n，162g混合物中氧原子的数目为(162g/162ng·mol-1，故A正确；B. 该选项没有说明溶液的体积，故无法计算微粒的数目，故B错误；C. CH3COO-在溶液中可以水解，所以数目小于5N A，故C错误；D. 22.4LCl2，因为没有说明外界条件，故无法具体计算氯气的物质的量，故无法计算转移的电子数，故D错误。

故选A。

【点睛】计算溶液中的微粒数目,需要知道浓度和体积；知道气体体积计算气体的物质的量,需要运用气体摩尔体积,需要确定外界条件。

3.丙烯的结构简式如图所示, 下列关于丙烯说法不正确的是A. 能使酸性高锰酸钾溶液褪色B. 至少有 1 种同分异构体C. 最多 6 个原子共平面D. 与氯化氢发生加成反应, 加成产物可能有两种【答案】C【解析】【分析】根据有机物的机构特点分析其化学性质。

四川省蓉城名校联盟2020级高三第一次联考英语试题学校:___________姓名：___________班级：___________考号：___________一、阅读理解The ancient Lake Baikal has a wealth of beautiful surprises. Nature aside, the region is also rich with culture—home to the Buddhists and the Buryat ethnic minority. Here are some more highlights.Explore Olkhon IslandAbsorbing your wilderness—conquering fantasies in hiking and camping wild on the dramatic cliffs and sandy bays of Olkhon, Lake Baikal’s largest, sparsely-inhabited island. Visit the Olkhon Island in an old Soviet army jeep to view the largest of the shaman ritual sites and spot some Baikal seals sunbathing on the rocks below.Visit the Ivolginsky DatsanThe Ivolginsky Datsan is the largest and most important Buddhist center in Russia. As you walk around this complex of brightly-colored temple buildings and simple monastic(僧侣的)dwellings, keep a look out for white towers and trees decorated with colorful prayer flags. Spin the prayer wheels, admire the giant Buddha statue with the offerings of coins, colored silks and rice and listen to the chanting of the monks amid clouds of smoke.Hike the Great Baikal TrailThe Great Baikal Trail project aims to eventually surround Baikal with a series of paths. You can currently hike through a pine forest between the villages of Listvyanka and Bolshiye Koty, or from the picture—perfect fishing village of Baikalskoye to the cold Lake Slyudyanskoye via a striking cliff edge path.Dive inLegend has it that Baikal’s waters have miraculous properties, a swim in which gives you five extra years of life. The best places to take a dip include the golden sandy beaches along the northern shore of Olkhon Island, where the water of Maloye Morye(Little Sea)is at its shallowest and warmest, and at the long pebble beach in Severobaikalsk.Hit the hot springsThe land around Lake Baikal is alive with hot springs, particularly in the small spa town of Arshan, situated in the picturesque foothills of the snowpeaked Eastern Sayan Mountains. The town itself is shabby, but the 1920s Arshan Spa still has the power to cure all kinds of illswith the mildly sulphureous(硫磺的)mineral water, according to the local legend.1．If you believe in Buddhism, which place will you most possibly visit?A．Olkhon Island.B．The Ivolginsky Datsan.C．The Great Baikal Trail.D．Arshan.2．What can we know about from the passage?A．You can drive an old Soviet army jeep around Olkhon Island.B．You can hike through all forests with the Great Baikal Trail project.C．The water near Olkhon Island is the deepest so visitors can dive safely.D．The medical benefits of the hot springs in Arshan have not been proven.3．Where will you most likely to read the passage?A．In a medical magazine.B．In a geography textbook.C．In a travelling brochure.D．On a science website.On September 8th, 2022, Queen Elizabeth II, Britain’s longest-reigning monarch in history, died aged 96.

I know her loss will be deeply felt throughout the country, the Realms and the Commonwealth, and by countless people around the world.”“Queen Elizabeth II was the rock on which modern Britain was built,” Britain’s Prime Minister Liz Truss said in a statement.Earlier in the day, Buckingham Palace said the monarch was under medical supervision due to doctors’ concerns over her health. The royal family members soon rushed to Scotland to be at her side following the announcement.In the evening, royal staff hung obituaries(讣告)on railings in front of Buckingham Palace. Crowds braved the rain to pay their respects and many laid flowers outside Windsor Castle.Queen Elizabeth II has significantly reduced her public engagements since the death of her husband Prince Philip in April last year, and canceled or postponed many official engagements after being hospitalized in October last year. She was diagnosed with the coronavirus in February.Born on April 21, 1926, Elizabeth II was announced Queen after the death of her father, King George VI, on Feb. 6, 1952.

At the coach station in London I was collected by a teacher, Mr. Mell, and taken to Salem House, the school which Mr. Murdstone had chosen for me.The school was a large old building with a dusty playground, surrounded by a high brick wall. It looked strangely deserted. I was very surprised to find that none of the boys were there, and was told that they were all on holiday and that I had been sent there during the holidays as a punishment for my wickedness. The headmaster and teachers were on holidaytoo, all except for Mr. Mell, who had to look after me.I spent a whole month in that miserable place, doing my lessons in the dirty, empty classroom, which smelt of old food and unwashed boys. Every evening I had to eat my supper with Mr. Mell, and then go straight to bed. The worst thing was the sign I had to wear round my neck. It said: BE CAREFUL! HE BITES. I was only allowed to take it off when I went to bed.Although I was extremely lonely and unhappy at this time, I was not looking forward to meeting all the other boys. I felt sure they would laugh at me and especially at the sign I was forced to wear. But one day Mr. Mell told me that the headmaster, Mr. Creakle, had returned, and wanted to see me. So I went, trembling to his part of the house.I realized at once that Mr. Creakle lived much more comfortably than the boys or the teachers. He was a small, fat man with a purple nose, who was sitting in an armchair with a bottle and a glass in front of him.8．Which of the following best describes the school?A．Strange and crowded.B．Old and abandoned. C．Comfortable and empty.D．Filthy and smelly.9．Which can be the possible reason for the author’s being sent to the school?A．He needed a better environment for education.B．He bit someone and got punished.C．He was a wicked boy and was supposed to turn better.D．He was unhappy and lonely so he intended to meet other boys.10．How did the author feel when he was to meet the headmaster?A．Overjoyed.B．Terrified.C．Eager.D．Surprised. 11．What would the author write about in the paragraphs that follow?A．How he missed his parents.B．How Mr. Mell taught him lessons.C．How he communicated with Mr. Creakle.D．How Mr. Creakle comforted him and had a big dinner with him.Scientists have revealed just how dangerous energy drinks can be, and can cause a sudden heart attack in some cases. While we all probably assumed that the large amounts of caffeine contained in these drinks probably weren’t great for our health, a study has nowexplored how another common ingredient could be dangerous.Guarana, a plant containing caffeine, is commonly used in energy drinks and can often lead to unexpected reactions when combined with other ingredients. In the case of energy drinks, guarana is often combined with ginseng(西洋参)or taurine(硫磺酸)to improve flavouring.A study explained the risk of sudden heart attack in young people after consuming such drinks. They wrote: “It seems clear that energy drinks might lead to critical events relating to the heart and blood vessels in the young population, even some of which are unable to recover.” The scientists wrote that such drinks can lead to fatal events, with heart attacks often occurring without warning.A 2021 Australian study, published in the Nutrition Journal, surveyed 8,942 students aged from 12 to 17 years old. Of the sample, they found that eight percent of students reported drinking energy drinks at least once a week, while one in four students had consumed energy drinks at least once. While a study of a 21-year-old UK man was published in BMJ Case Reports in 2021, who had unexpectedly been experiencing a heart attack. The report stated: “There was no significant past medical history and he had no family history of heart attacks.” However, the man had explained he had been drinking four 500 ML energy drinks a day for approximately two years—with each drink containing 160 mg of caffeine. The study added: “Given the history of long-term energy drink consumption, lack of significant past medical or family history, heart imaging findings and improvement with ceasing intake, energy drink-caused cardiotoxicity(心脏毒性)was felt to be the most likely cause.”12．What does the underlined word “fatal” in paragraph 3 probably mean? A．Energetic.B．Deadly.C．Occasional.D．Significant. 13．Why is ginseng added to energy drinks?A．To make the drinks more nutritious.B．To make the drinks more effective. C．To make the drinks taste better.D．To make the drinks more expensive. 14．What can be inferred from the last paragraph?A．The ages of the participants range largely.B．Most students surveyed drink energy drinks once a week.C．The family members of the 21-year-old UK man are all very healthy.D．The conclusion that the illness was caused by energy drinks was based on several factors.15．What is the main idea of the passage?A．Energy drinks may cause heart attacks in young people.B．Some studies about energy drinks are carried out.C．Young people consume a large amount of energy drinks.D．Energy drinks lead to critical events.二、七选五It’s almost impossible to totally avoid stress, but these top tips will help you to get it under control so that it doesn’t take over your life.____16____Studies of both animals and humans show that social contact can help avoid body’s stress. So cultivate a network of people you can turn to share what’s bothering you with a friend and ask for some helpful advice.

四川省成都市蓉城名校联考2024-2025学年高三上学期入学考试英语试题一、阅读理解Best Places to Travel in 2024Get your suitcase ready, because we came up with the definitive list of the best places to travel this year. These trips will be epic!CambodiaCambodia is a must-see destination for many travelers. With the addition of luxury hotels and vacation land, travelers can now enjoy a truly luxurious experience in Cambodia — mixing ancient ruins and culture, cuisine and handicrafts, rainforest and jungle, and ending with a wonderful beach stay. In the little-visited Cardamom Forest Protected Area, options for hiking, mountain biking, boating and bird-watching are plentiful.ParosVisiting the island is one of the best things to do in Greece since it means enjoying pleasant beaches surrounded by the blue waters of the Aegean Sea. While you’re here, explore the winding streets and charming villages of Naoussa and Lefkes, and drink coffee or wine at the beautiful port of Parikia.TexasAs far as natural wonders go, it’s hard to beat a total solar eclipse (日食) for impressiveness… and for being easily predictable. But even if you know the eclipse’s path, you’ll still need to get to a spot with good visibility. That’s where Texas comes in.Ras Al KhaimahRas Al Khaimah is a great spot for outdoors y types, who can swim in the clear blue waters, then head off for a quad biking (四轮摩托车) adventure in the desert or fly across the desert on the world’s longest zipline. If you get a chance to spend New Year’s Eve here, don’t miss it. The Emirate holds multiple Guinness World Records for its magnificent fireworks performances held during its New Year’s celebrations.1．What do Cambodia and Paros have in common?A．They own well-known ports.B．They have delightful beaches.C．They offer options for boating.D．They host recent sporting events.2．Which place will you choose for a clear view of a total solar eclipse?A．Cambodia.B．Paros.C．Texas.D．Ras Al Khaimah. 3．What is special about Ras Al Khaimah?A．It is known for its colorful nightlife.B．It has some fantastic beaches in the world.C．It is home to ancient ruins and cultural sites.D．It offers adventurous activities like motorcycling.I recently watched the Arnold Schwarzenegger documentary on Netflix, and I have to tell you how impressed I was with his life story.I remember back in high school when my girl Clara and I were the only two girls in the gym working out and lifting weights. Yes, this was back in the dinosaur days when girls didn’t go to the gym. There were all these posters around Arnold. He was the bodybuilder of the day. He won the Mr. Universe title aged 20, and subsequently the Mr. Olympia title seven times. He is widely regarded as one of the greatest bodybuilders of all time and has written many books and articles about it. He was a hero to so many of us gym rats.But what got me was his determination to get where he is today. He had a dream, and he went after it. He came from a small town on the other side of the world. They said he couldn’t make it in bodybuilding, but he went on to be one of the world’s most famous bodybuilders. They said he would never be an actor because of his accent, but in spite of that, he became box office gold. They said he had no potential for becoming a governor, but he showed them, winning not one but two terms in office and making some world changes while in there.He didn’t let anything or anyone stop him from what he wanted. No matter how many disappointments, how many failures, or how many people told him he couldn’t do it, it just made him more determined to prove them wrong.So today, my friends, the lesson here is to never give up, to hold onto your dream no matter how crazy others may think it is. To work hard and despite how many times you get knocked down or told no, that you keep fighting. Because as you can see here, dreams do come true. 4．What first inspired the author’s admiration for Schwarzenegger?A．His career as an actor.B．His success in politics.C．His contributions to literature.D．His achievements in bodybuilding.5．How did Schwarzenegger demonstrate his determination?A．By directing a film.B．By realizing his dreams.C．By telling his life story.D．By voting for a governor.6．What message does the author seem to convey in the text?A．The value of setting achievable goals.B．The necessity of seeking fame and recognition.C．The importance of maintaining physical fitness.D．The significance of perseverance and determination.7．Where is this text most likely from?A．A diary.B．A guidebook.C．A blog.D．A novel.For years, Egyptologists have hotly debated how the massive pyramids (金字塔) of ancient Egypt (埃及) were built more than 4,000 years ago. Now, a team of engineers and geologists brings a new theory to the table—a water lift device that would have floated the heavy stones up through the middle of Egypt’s oldest pyramid using stored water.Ancient Egyptians built the Step Pyramid for Pharaoh Djoser in the 27th century BC, and it was the tallest structure at the time, coming in at about 62 meters tall. But how exactly the structure was erected, with a number of stones weighing in at 300 kilograms, has remained a centuries-old mystery, according to the study published Monday in the journal PLOS One.“Many detailed publications have discussed pyramid-building procedures and provided real examples, but these usually focus on more recent, better-documented, and smaller pyramids of the Middle and New Kingdoms (1,980 to 1,075 BC),” said lead author Dr. Xavier Landreau, CEO of Paleotechnic, a privately owned research institute in Paris that studies ancient technologies.“The techniques involved could include ramps (活动坡道), cranes (起重机), or a combination of these methods,” he added in an email. “But what about the Old Kingdom pyramids (2,675 to 2,130 BC), which are much bigger? While human strength and ramps may be the only construction force for small structures, other techniques may have been used for large pyramids.”Using a combined approach, the new paper was the first to report a system matching the Step Pyramid’s internal architecture, the authors wrote.A complex water treatment system drawing upon local resources could have created a water-powered elevator within the pyramid’s internal vertical passage. Some type of float would have raised the heavy stones up the middle of the pyramid, according to the study.8．What does the underlined word “erected” in Paragraph 2 probably mean?A．Changed.B．Designed.C．Built.D．Destroyed. 9．Which may play a role in building small pyramids according to Dr. Landreau?A．People and ramps.B．Ramps and cranes.C．People and cranes.D．Water and ramps.10．What is the main advantage of the water lift device in building pyramids?A．It simplifies the use of ramps.B．It helps to make heavy stones raised.C．It increases the weight of the stones.D．It uses some resources for treatment.11．What is the best title for the text?A．Water Lift Theory: A New View on Pyramid ConstructionB．Recent Researches on the Stories of Egypt’s Small PyramidC．A Historical Debate: Egypt’s Pyramid Construction SecretsD．Exploring Ancient Egyptian Pyramid Construction MysteriesA new study by an international team of experts highlights how global methane (甲烷) emissions have been rising rapidly since 2006, particularly since 2020, a trend that’s expected to continue unless we do something very significant very soon. The study authors have then outlined some strategies countries can use to take action, and developed an online tool to help with this.This continual climb in methane emissions is largely due to the continued use of fossil (化石) fuels rather than cleaner options, the researchers say. It’s directly produced by oil, gas, and coal drilling and processing. The increasing release of methane from natural wetlands, caused by a hotter climate, is now also contributing. Methane is produced by rubbish sites, thawing permafrost, and animals too. The researchers, led by physicist and climate specialist Drew Shindell of DukeUniversity in the US, suggest these are minor contributors at the moment — although ones that also need to be closely watched.“Worldwide efforts to limit climate change are rightly focused on carbon dioxide (CO2), the primary driver,” writes the team in their published paper.“However, since humanity has failed to properly address climate change for several decades, keeping warming below agreed goals now requires that we address all major climate pollutants.”There is currently much less methane in our atmosphere than carbon dioxide (CO2), but methane is a stronger greenhouse gas.We know that methane is a major contributor to the warming of the world, trapping heat like CO2 does. It also contributes to the formation of ozone (臭氧) at ground level, increasing the risk of death through respiratory illnesses and cardiovascular diseases.“Rapid reductions in methane emissions this decade are essential to slowing warming in the near future, limiting overshoot by the middle of the century and keeping low-warming carbon budgets within reach,” write the researchers.Warnings from scientists about the state of Earth’s climate path are now reaching a deafening level. Humanity should pay close attention to those warnings and take action. 12．What do we know about methane emissions?A．They are currently a minor concern.B．They have been going up since 2006.C．They have decreased steadily since 2020.D．They are mainly caused by cleaner options.13．What is the second paragraph mainly about?A．The continued use of methane emissions.B．Strategies for reducing methane emissions.C．The impact of methane emissions on human health.D．The contributions of sources to methane emissions.14．Why is reducing methane emissions considered urgent?A．Methane lessens the amount of ozone.B．Methane limits climate change effectively.C．Methane promotes global warming greatly.D．Methane keeps low-warming carbon budgets.15．What is the author’s purpose in writing the text?A．To call on people to handle methane emissions.B．To introduce the history of methane emissions.C．To highlight the dangers of methane formation.D．To advocate for the increased use of fossil fuels.How to Boost Self MotivationMotivation is what drives you to take positive action. 16 . The first is self-motivation, which comes from within ourselves. The second is motivation from external sources. How do we get motivated and more importantly, how do we stay motivated? Here are some tips to help us stay motivated.Set goals. 17 . The first step to achieving a dream is to turn it into a series of goals.A long-term goal will be the ultimate dream — let’s say, setting up a new business. Short-term and medium-term goals will be the stages on the road to the final goal.Avoid Loans. Having some money behind you before you set off on your quest for success is good. Do not, however, try to fund your life with loans and credit cards. Avoid them if you can. Worry over debt is another way of destroying self-motivation. If your dream is to set up a business, keep the business finances separate from your personal finances. Do not, for example, be tempted to use your house as security for any business loans you might be arranging. 18 .Have self-belief. When you are faced with a failure, don’t just let it defeat you. Remember that you have already overcome other blocks. 19 . Trusting your capacity for success is a brilliant motivator. You know you can solve the problem facing you because you have done it before.20 . You will already have drawn up your plan of action and the timetable for carrying it out. Keep this in mind at all times, and you will continue to be motivated. Your plan itself is a source of self-motivation. Review your progress from time to time to make sure that you are still on course for success.A．Stick to the planB．Keep your motives in mindC．Motivation comes in two typesD．Our dreams are usually a bit unclearE．Believe in yourself and your abilitiesF．This is another unavoidable cause of stressG．It is important not to worry about losing motivation二、完形填空A spinal injury dashed Adriana Ruano’s dreams of competing in the Olympics as a gymnast.
