2021届广东省普宁市第二中学高三下学期第一次阶段考试语文试题
2020-2021学年度普宁市第二中学第一学期高三语文第1次阶段考试卷一、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1一3题。
什么东西都可以低估，但唯独不能低估青春的能量；青年时期的积累与沉淀，往往影响着一个人一生的发展。
诗人艾青有句名言：“为什么我的眼里常含泪水，因为我对这土地爱得深沉。
”家国情怀是一种源自内心的质朴情感，也可说是每个人的立身之本。
对于当代青年来说，只有常怀感恩之心、砥砺家国情怀，才能自觉地把个人的前途命运与国家、民族、社会紧密地融合在一起。
家国情怀深深植根于我们的灵魂之中，内化于心、外化于行，铭刻于骨、融化于血。
家国情怀既体现为一种民族大义，也是庚续传承的文化传统。
大禹治水三过家门而不入，戚继光抗倭保家卫……回溯既往，从神话故事到历史典故，浓浓的家国情怀之中，都体现着民族大义。
《礼记大学》的“修身、齐家、治国、平天下”，屈原的“路漫漫其修远兮，吾将上下而求索”，范仲淹的“先天下之忧而忧，后天下之乐而乐”……家国情怀世代相传，成为中国人的一种文化基因。
事实证明，没有伟大的国家和民族，就难言个人的尊严。
因此，无论何时，我们都应将家国情怀牢记在心。
人无精神不立，国无精神不强。
家国情怀突出体现为爱国奉献的精神，堪称一种精神坐标。
邓小平同志曾说：“我是中国人民的儿子，我深情地爱着我的祖国和人民。
”真挚的话语，饱含着爱与真情，这正是浓厚家国情怀的写照。
“家是最小国，国是千万家”。
爱国不能停留在口头上，而应体现在行动之中。
西藏玉麦乡牧民卓嘎、央宗姐妹的事迹为什么感动了亿万人？就在于她们以行动诠释爱国情感，为祖国守护神圣土地。
对于个体而言，要关注国家为我们做了些什么，更要多问问自己为国家能做什么、做了些什么。
可以说，家国情怀需要我们爱国、奉献、担当、作为，在日常工作生活中不断升华爱国奋斗精神。
今天，家国情怀更体现为一种时代责任。
奋进在新时代，亟待我们激荡新气象、成就新作为，为实现中华民族伟大复兴的中国梦凝聚磅礴力量。

AIt’s almost camp season!Summer is wonderful. Summer at one of the following awesome camps? Even more wonderful. Tahosa High Adventure BaseLocation: Ward, ColoradoPeople puzzle: Tahosa’s ropes courses are some of the nation’s best. Use your hands, feet and brains to take up high-flying challenges and overcome your fears. Fly fishing at 9,000 feet? Yes. Fishing licenses or experience needed? No, sir!Choose your adventure: Go all-inclusive, where the staff prepares meals and runs the program, or take control and plan your perfect week. The choice is yours.Camp RaymondLocation: Parks, ArizonaDon’t look down: When looking up at the stars, light pollution is your enemy. But Camp Raymond’s location and elevation (海拔) of 6,700 feet offer perfect conditions for seeing otherwise invisible stars.That’s cool: Don’t forget your camera and a jacket. During the day, you could spot bears and deer. At night, temperatures can fall sharply. Hot cocoa at summer camp? Cool.Pamlico Sea BaseLocation: Blounts Creek, North Carolina.Go coastal: Explore the Carolina coast by boat. You choose the route, and Pamlico provides the equipment. Keep an eye out for wild horses, lighthouses and boatloads of fish.Set sail: Even if you don’t know the difference between starboard and star-lord, Pamlico’s sailingjourney will make you a first-rate sailor in no time. You’ll even practice finding your way using the stars.Base CampLocation: St. Paul, MinnesotaBig upgrade: What happens when you change a 1907 cavalry drill hall (骑兵训练场) into an adventure destination in the heart of the city? You get Base Camp for overnight lock-ins, weekend retreats (隐居处) and summer camp.Inside out: Most of Base Camp is indoors, meaning the activities like climbing walls can be undertaken on winter’s coldest days.1. What do we know about Tahosa High Adventure Base?A. It requires fishing licensesB. It offers lessons on flying a planeC. It’s a camp that is intended for brave kidsD. It is a camp where you can set your own pace2. What can be learned in Pamlico Sea Base?A. How to tell starboard from star-lord B How to choose camping equipmentC. How to use the stars for directionsD. How to make a boat on your own3 In which camp can kids climb walls inside on winter days?A. Base CampB. Camp RaymondC. Pamlico Sea BaseD. Tahosa High Adventure Base.B“You’ll be blind by the time you’re twenty-five,” a doctor at Children’s Hospital predicted. “Your blood sugars are much too high.” It consumed me. No matter where I was or what I was doing, it was overhead like a dark cloud, waiting for just the right opportunity to break open and destroy my world.I liked painting. Losing myself in painting filled me with peace. Painting provided me with the only place where I could escape from those threatening words.When I was twenty-one, my right eye went blind. Precisely three months after my twenty-fifth birthday, I had a massive hemorrhage (大出血) in my left eye because of an accident. For the next twenty years, vision came and went. I went through many eye operations in an attempt to keep my vision. But after one final operation, I lost the battle and all remaining vision. And I buried all dreams of painting.Desperate, I enrolled in (注册) a sixteen-week program for the blind and visually impaired (损伤的). I learned personal adjustment and the use of a computer with adaptive software. A whole new world opened up to me through this program.“Jaws and Window-Eyes are leading software for the blind,” my instructor told me. “You can use the Internet, e-mail and Microsoft with all its tools and features.” It’s amazing! Hope went up for the first time in years. “By learning how to use hot keys to control the mouse, you can use Microsoft Access, Excel and Powerpoint,” my instructor added.For the next several years, I learned that when one door closes, another door opens. There are plenty of choices available for the blind and visually impaired through the gift of technology. Not only do I have a speaking computer, but I have a speaking watch, alarm clock and calculator.4.What does the underlined word “it” in Paragraph 1 refer to?A. The right opportunity.B. Losing my sight in the future.C. Consuming too much sugarD. The children’s hospital.5. What happened when the author was 25 years old?A. He gave up painting.B. He went blind completelyC. He injured one of his eyes.D. He picked up a new hobby6. What brought a turning point to the author?A. A special course.B. A meaningful eventC. An inspiring speech.D. An important interview.7. What does the author intend to tell us?A. No pain, no gain.B. Every man has his price.C. Nothing is impossible to a willing heart.D. Be optimistic in the face of life’s difficulties.CThese days, I walk down the steps leading toward the south end of the All England Club in Wimbledon, and still look for the Crow’s Nest, a small green observation tower with an outer ladder that I used to climb on for a wide view of the grounds, but which has since been knocked down.The Crow’s Nest was a particularly useful point, because it allowed a tennis writer to keep trackof the action on as many as 10 outside courts at a time. At days end, reporters from different nations would share notes on what they had observed all over the grounds.Twenty-seven years later, the press room has touch screens that allow us to watch live videos fromany court, and even go back to watch key moments in key matches long after they have finished. You could cover Wimbledon without leaving your seat. But that is a bit like spending all your time ordering room service and looking up fun facts on Wikipedia.More than at any other tennis tournament, there is also an appetite for stories that deal with the setting, the history and the traditions.If they change the price of the fish tacos (鱼肉卷饼) at the United States Open, it’s not a story. If they change the price of the strawberries and cream, the signature treat at Wimbledon. It’s time to email your editor using capital letters.The new retractable (可伸缩的) roof was put in place in 2009. Until then, you always had to have a rainy-day story in your notebook because there were no guarantees any matches would be played. Now tennis is a sure thing on Centre Court, which has made tennis reporters a bit less creative. But at least it guarantees us daily access to the most atmospheric place in the sport.So much has changed, but Centre Court remains true to its original spirit: more a theater than a stadium. Catching that feeling is part of covering Wimbledon, too.8. What did the author do on the Crow’s Nest in the past?A. He made friends with reporters.B. He reported on tennis matches.C. He appreciated the beautiful scenery.D. He exchanged experiences with tennis players.9. What does the author think of the new way of covering Wimbledon?A. It lacks fun.B. It is expensiveC. It is not convenient.D. It is not quick enough10. Why does the author mention strawberries and cream?A. To compare popular foods.B. To introduce the typical treat at Wimbledon.C. To describe people’s craze for traditional dishes.D. To show the traditions of Wimbledon are an attraction.11. What difference does the new roof make?A. Audiences have easier access to a tennis court.B. There’s less fun in watching Wimbledon indoors.C. Reporters are struggling to find original material.D. rainy-day stories about Wimbledon have become history.DOn January 13, 2016, France became the first country in the world to pass a law requiring supermarkets to donate food that is approaching its expiration date (保质期) instead of throwing it away. The regulation that applies to supermarkets over 4,000 square feet requires stores to sign official donation agreements with local food banks.The law also makes it illegal for stores to pour water over nearly-expired food, or store it inside locked warehouses until it is picked up by the garbage trucks. These measures are often undertaken by supermarkets to prevent the hungry from searching for food through the dustbins.Though that may appear cruel, the stores claim they do it to avoid potential food poisoning that could occur if the product is on its way past its expiry. Those who do not obey the new law face the risk of heavy fines.Also, excess goods like yogurt or milk that are likely to go bad quickly are now allowed to be donated directly to the food banks. Though this has always been possible, the current process is long and complex, making it difficult for producers to give away the food in a timely manner.France’s food banks are of course thrilled about the possibility of receiving extra food. Jacques Bailet, who heads a network of French food banks called the Banques Alimentaires, says that of the 110,000 tons of goods received annually, only 36,000 tons comes from supermarkets. Bailet estimates (估计) that just a 15% increase in supermarket donations would translate to over 10 million additional meals to feed the hungry each year.Though this is a great first step, Arash Dermabarsh, the activist responsible for the grassroots movement that led to the ban, is not done. He now wants to extend the law to other places like restaurants and also try to convince other countries in the European Union to pass similar regulations. These steps are necessary because of the over 9 million tons of food wasted in France; an astonishing 67% is thrown away by consumers, with supermarkets and restaurants making up the rest.12. What should stores do with nearly-expired food?A. Throw it away.B. Send it to the hungry.C. Store it in refrigerators.D. Give it away to food banks.13. What does the underlined word “excess” in Paragraph 4 probably mean?A. Extra.B. Cheap.C. Seasonal.D. Returned.14. What might Bailet agree with about the French food banks?A. They have a lot of expired food.B. They will get much benefit from the law.C. Their food is enough for the people in need.D. Their food mainly comes from supermarkets.15. What does Dermabarsh plan to do?A. Build more food banks in France.B. Make the law take effect in more places.C. Organize a campaign to promote this law.D. Raise consumers awareness of waste reduction.第二节（共5小题；每小题2分，满分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。

AIt’s surprising how much simple movements of the body can affect the way we ing expansive gestures with open arms makes us feel more powerful,crossing your arms makes you more determined and lying down can bring more insights(领悟).So if moving the body can have these effects,what about the clothes we wear?We’re all well aware of how dressing up in different ways can make us feel more attractive,sporty or professional,depending on the clothes we wear,but can the clothes actually change cognitive(认知的)performance or is it just a feeling?Adam and Galinsky tested the effect of simply wearing a white lab coat on people’s powers of attention.The idea is that white coats are associated with scientists,who are in turn thought to have close attention to detail.What they found was that people wearing white coats performed better than those who weren’t.Indeed, they made only half as many errors as those wearing their own clothes on the StroopTest(one way of measuring attention).The researchers call the effect“enclothed cognition,”suggesting that all manner of different clothes probably affect our cognition in many different ways.This opens the way for all sorts of clothes-based experiments.Is the writer who wears a fedora more creative?Is the psychologist wearing little round glasses and smoking a cigar more insightful?Does a chef’s hat make the resultant food taste better?From now on I will only be editing articles for PsyBlog while wearing a white coat to help keep the typing error count low.Hopefully you will be doing your part by reading PsyBlog in a cap and gown(学位服).1.Adam and Galinsky’s experiment tested the effect of clothes on their wearers’___________.A.insightsB.attentionC.movementsD.appearance2.How does the author sound in the last paragraph?A.Humorous.B.Academic.C.Formal.D.Hopeful.3.What is the main idea of the text?A.Body movements change the way people think.B.How people dress has an influence on their feelings.C.People doing different jobs should wear different clothes.D.What people wear can affect their cognitive performance.BMy mother always said,"You young men should explore your own country before stepping out into the world."It seemed like a tough task.But luckily for me,Via Rail Canada offered youths between the ages of18and25the chance to ride the train across Canada for the month of July in2017.I jumped at the opportunity and secured an inexpensive ti cket.Excitement was at its peak as I approached the train station on the morning when my22-day adventure was to begin.I jumped on board the passenger vessel(车厢)like it was the train to Hogwarts in Harry Potter.The train headed west in search of our first destination—the scenic town of Banff,Alberta. After just an hour on the train,desperation already came on me.The thought of three full days on those tracks broke my spirits.As I gazed out towards Lake Superior's glistening(闪闪发亮)waves,I decided if I was to be stuck in here,I would need to enjoy my time.Those three days turned into a summer camp on rails.Real friendships with the crew were born within that train.Stops were made in small,remote railroad villages.A large group of strangers turned travelling companions would rush towards the villages to reward our endless patience with local cuisine.At night,we would walk to the glass-domed(玻璃穹顶)train car,which gave a scenic view of the night sky,untouched by light pollution.After three days,we arrived in Banff.Before my adventure of taking the train across Canada,if I could have skipped the travel and arrived at the destination,I would have.But that is no longer true.I'velearned that the journey can be more enjoyable than the destination.4.What made the author's train trip possible?A.The attraction of the splendid scenery.B.A time-limited ticket offer for youths.C.The encouragement from his mother.D.His determination to face the tough tasks.5.Which of the following best describes the author as a young man?A.Considerate.B.Determined.C.Smart.D.Adaptable.6.What has the author learned from his adventure?A.To enjoy travelling on his own.B.To skip to the final destination.C.To explore more in the process.D.To be content with train service.CLife expectancy in the United States has been in decline for the first time in decades,and public health officials have identified a series of potential causes,including inaccessible health care,rising drug addiction and rates of mental health disorders,and socio-economic factors.Now,a study led by the Yale School of Medicine has attempted to find out the relative impact of two factors most often linked to life expectancy–race and education–by looking at data about5,114black and white participants in four U.S. cities.The lives and deaths among this group of people–who took part in the study approximately30ye ars ago when they were in their early20s–show that the level of education,and not race,is the best predictor of who will live the longest.Among the5,114people followed in the study,395had died.These deaths were occurring in working-age people,often with children,before the age of60.The rates of death among participants in this group did clearly show racial differences,with approximately9%of blacks dying at an early age compared to6%of whites.There were also differences in causes of death by race.For instance,black men were significantly more likely to die of murder and white men from AIDS.The most common causes of death across all groups over time were cardiovascular disease and cancer.But there were also obvious differences in rates of death by education level.Approximately13%of participants with a high school degree or less education died compared with only approximately5%of college graduates.Strikingly,when looking at race and education at the same time,the researchers found that differencesrelated to race almost disappeared:13.5%of black subjects and13.2%of white subjects with a high school degree or less died during the course of the study.By contrast,5.9%of black subjects and4.3%of whites with college degrees had died.Therefore,improving overall quality of education is something tangible that can help reverse(扭转) this troubling trend in reduction of life expectancy among middle-aged adults.7.What can we learn about the participants in the study?A.The whites are more aggressive.B.The whites got higher education.C.More blacks than whites died young.D.More whites than blacks died of cancer.pared with education,the influence of race on death rates is______.A.unnoticeableB.growingC.long-lastingD.significant9.What does the underlined word“tangible”probably mean?A.Temporary.B.Realistic.C.Challenging.D.Creative.10.What can be inferred from the research findings？A.People can get smart through learning.B.One should not discriminate other races.C.One can live longer by getting more education.D.People don’t enjoy equal rights for education.第二节（共5小题；每小题2分,满分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。

“城镇收缩”指在城镇发展过程中，城市总人口不断萎缩的现象。
“中国林都”—黑龙江省伊春市以林业为主，产业结构单一，今年来出现了较为显著且持续发展的城镇收缩现象。
下图示意伊春市城镇发展不同阶段人口、经济和用地规模变化，图中外三角形数值大于内三角形数值。
读下图完成下面小题。
1. 伊春市“城镇收缩”的主要原因是（）A. 农村人口少B. 经济衰退C. 老龄化严重D. 气候寒冷2. 能正确反映伊春市“城镇收缩”先后顺序的是（）A. 甲丙乙B. 丙甲乙C. 乙甲丙D. 乙丙甲3. 与甲阶段相比，乙阶段内伊春市（）A. 交通拥堵加剧B. 土地集约度提高C. 人均产值增加D. 服务范围扩大【答案】1. B 2. B 3. C【解析】【分析】【1题详解】材料信息表明，“城镇收缩”指在城镇发展过程中，城市总人口不断萎缩的现象。
由此推断，伊春市“城镇收缩”的主要表现是城市人口减少，当地人口自然增长为正，那么城市人口减少应人口迁出所致。
如果当地农村人口少，只会导致城市人口增长速度较慢，不会导致城市人口数量减少，排除A；材料信息表明，伊春市以林业为主，产业结构单一，因此经济发展受阻，经济衰退，提供的就业机会少，大量城市人口向外迁移，导致城镇收缩，B符合题意；老龄化严重是当地“城镇收缩”的结果，不是原因，排除C；气候寒冷有可能使得部分人迁出，但一直以来，当地就具有冬季气候寒冷的特征，因此这不是当地伊春市“城镇收缩”的主要原因，排除D。
