ALost cities that have been foundThe White CityIn 2015, a team of explorers to Honduras in search of “the Lost City of the Monke God” led to the discovery of the White Cit y. They found the ruins in the Mosquitia region of the Central American country which is known for poisonous snakes, vicio us jaguars and deadly insects. It is believed that local people hid here when the Spanish conquerors(征服者) occupied their homeland in the16th century.Canopus and HeracleionModern researchers were teased by the ancient writings abou t the Egyptian cities Canopus and Heracleion -- where Queen Cleopatra often visited. But the cities weren’t f ound until 1992, when a search in Alexandria waters found th at the two cities had been flooded for centuries. Artifacts(史前器物) showed that the cities once highly developed as a trade n etwork, which helped researchers piece together more about t he last queen of Egypt.Machu PicchuA Yale professor discovered “the Lost City in the Clouds” in 1 911. A combination of palaces, plazas, temples and homes, Machu Picchu displays the Inca Empire at the height of its rul e. The city, which was abandoned in the 16th century for unkn own reasons, was hidden by the local people from the Spanis h conquerors for centuries keeping it so well preserved.TroyThe ancient city of Troy in Homer’s The Iliad was considered a fictional setting for his characters to run wild. But in 1871, ex plorations in northwestern Turkey exposed nine ancient cities layered (层叠) on top of each other, the earliest dating back to about 5,000 years before. It was later determined that the sixth or seventh layer contained the lost city of Troy and that it was actually destroyed by an earthquake, not a wooden horse.21. Why did people hide in the White City in the 16th century?A. To survive the war.B. To s earch for a lost city. []C. To protect their country.D. To a void dangerous animals.22. Which of the following was related to a royal family memb er?A. The White CityB. Can opus and HeracleionC. Machu PicchuD. Troy23. What can we learn about Troy?A. It was built by Homer.B. It co nsisted of nine cities.C. It had a history of 5,000 years.D. It was ruined by a natural disaster.BWhen 1 was a boy we used to live across the road from a big hill with huge oak trees growing out of it. When winter arrived, thick, heavy snow would fall, and my two brothers would grab their sleds heading over to the hill for a day of fun.I rememb er watching them with envy because 1 was still too small to g o sledding. Finally, one winter 1 was considered big enough a nd joined my brothers as they carried their sleds up the long h ill and prepared to ride down it.The first few trips I rode with one of my brothers and had the ti me of my life. It was so exhilarating when the wind whipped a cross my face as I flew down the hillside on the wooden sled. Near the end of the day 1 was overjoyed too when my oldest brother decided to let me try riding the sled all by myself. I cli mbed on it full of excitement and lay on my stomach. Then wit h one big push my brother sent me down the snowy hillside. 1 was doing pretty well too until I hit an old stump hidden by th e snow and went off course, straight towards one of those big oak trees. My heart pounded in my chest and I could hear my self screaming. At the last possible second I rolled off and the sled crashed into the tree. I could hear my brothers running down the hill yelling, “Y ou have to steer(操控)! You have to steer!”Sadly, that wasn’t the last time I failed to steer when some obstacle knocked me off course in my life. Many times proble ms, troubles, and my own failures have sent me crashing into the trees of anger, frustration, and despair. I am still learning t hat life isn’t always safe sledding I am still learning that it is up to me to steer myself back to love, back to kindness, back to goodness, and back to God.Life is a trip, but no one ever said it was a smooth ride. Ste er well then. Steer straight. Steer your soul towards the light a nd the love we are all meant for.24. What do we know about the author when he was very you ng?A. He lived on a big hill with huge oak trees on it.B. He was frightened to go sledding with his brothers.C. He longed to go sledding with his brothers.D. He carried his brothers’ sleds as they went sledding.25. Which of the following can replace the underlined word “e xhilarating” in Paragraph 2?A. delightfulB. terrifyingC. ordinaryD. violent26. Why did the author fall off his sled?A. Because his sled crashed in an oak tree.B. Because he lost control of his sled.C. Because his brother pushed it so hard.D. Because the hillside was snowy.27. What does the author mean to tell us?A. Losing control of a sled can be dangerous.B. Courage and determination can change one’s life.C. Life can be controlled by one himself.D. Life is a mystery full of coincidences.CChinese audiences seemed not to have been satisfied with th e third season of the highly anticipated food documentary A Bi te of China.Picky viewers complain that some of the narration is not accur ate, while others pinpoint misleading content. At the same tim e, food blogger @barbara questioned whether it is appropriat e to give a close-up shot of the poisonous plant Nandina(南天竺)in a food program.A Bite of China, which debuted in 2012, became hugely popul ar nationwide for its quality introduction of some rarely-known and mouth-watering domestic cuisine. In the new show, however, watche rs are not satisfied with “irrelevant” food references, such as li psticks made of Chinese traditional medicine and martial arts master.The first episode introduced a hand-made iron frying pan from east China’s Shandong province, w hich prompted thousands of Chinese Internet users to buy on e from China’s leading e-commerce website Tmall in the next few days. Sales of the pa n at “Zhensanhuan” surged 6,000 times compared with a year ago, according to Beijing Youth Daily.In response to overwhelming criticism and questions, A Bite o f China production crew responded on Weibo that they seek i nnovation despite the risks following the first two phenomenal seasons.“It is unavoidable to make comparisons with the first two, and some audiences may not accept the changes,” the crew said. “We explore the culture and civilization behind food, and give food a historic touch. That’s why we feature culinary(烹饪的)tools, feast and rituals, as well as a healthy diet to show Chin ese wisdom and philosophy, which has not been shown in any food programs before.”28. Why does the passage mention Nandina?A. Because some of the narration is not accurate.B. Because it may be improper to give a close-up shot of a poisonous plant.C. Because it is misleading content.D. Because it is not attractive at all to most picky viewers.29. Which of the following elements leads to viewers’ dissatisf action with the new show?A. some mouth-watering domestic cuisinesB. food-unrelated itemsC. some rarely-known cuisines D. the increasing sales of the pan at “Zhensanhuan”30. According to its production crew, what is unique to ‘A Bite of China III’?A. It makes comparisons with the first two episodes.B. It tells the story of some martial arts related to food.C. It receives overwhelming criticism and questions from audi ence.D. It focuses on cooking tools, rituals and healthy eating.31. What is the best the title for the passage?A. A Bite of China III' Draws Criticism from AudiencesB. A Bite of China III' Maintains High Viewership RatingsC. A Bite of China III' Changes for the WorseD. A Bite of China III' Explains its PurposesDThe organic food has gained a lot of popularity as they are bei ng considered as healthier and tastier. A fair number of peopl e advocate a large-scale shift to organic farming from conventional agriculture. B ut this might not seem well-founded.Since the mid-19th century, conventional industrial agriculture has become i ncredibly efficient on a simple land to food basis. Conventiona l farming gets more and more crop per square foot of land, wh ich can mean less wilderness needs to be transformed to far mland.To make farming more efficient, conventional agriculture uses a significant amount of synthetic fertilizer(合成肥料) each year, and all that nitrogen(氮) enables much faster pl ant growth. However, the cost is paid in vast polluted dead zo nes at the mouths of many of the world’s rivers, because much of the nitrogen ends up running off the soil and into the ocea ns. This also makes conventional farming one of the major thr eats to the environment.To weaken the environmental impact of agriculture, improve s oil quality as well as produce healthier foods, some farmers h ave turned to organic farming. Environmentalists have also w elcomed organic food as better for the planet than the food pr oduced by agricultural corporations. Organic practices—refusing artificial fertilizers and chemical pesticides—are considered far more sustainable. Sales of organic food ro se 7.7% in 2010, up to $26.7 billion—and people are making those purchases for their moral sense s as much as their tongues.Yet a new meta-analysis in Nature does the math and comes to a hard conclu sion: organic farming produces 25% fewer crops on average t han conventional agriculture. This is definitely a downside of o rganic farming, especially when global population is still growi ng rapidly.In the Nature analysis, scientists performed an analysis of 66 studies comparing conventional and organic methods across 34 different crop species, from fruits to grains. They found tha t organic farming delivered a lower output for every crop type,though the difference varied widely. For crops like fruit trees, organic trailed conventional agriculture by just 5%. Yet for maj or grain crops and vegetables—all of which provide the world’s main calories—conventional agriculture outperformed organics by more than 25%.What that means is that while organic farming may be more s ustainable than conventional agriculture, there are trade-offs(此消彼长) with each. So an ideal global agriculture system may borr ow the best from both systems rather than upholding merely o rganic or conventional practices.32. The purpose of the passage is to ___________.A. compare two types of farmingB. criticize conventional agricultureC. discuss the development of farmingD. argue for a realistic agriculture system33. According to the passage, conventional farming ________ ___.A. produces more crops with fewer fertilizersB. achieves efficiency at a huge cost to the environmentC. offers a long-term solution to global demand for foodD. performs far better for each crop type than organic farming34. The author may agree with ___________.A. employing organic farming to plant riceB. adopting organic practices to grow potatoC. using conventional methods to plant cabbageD. applying conventional farming to growing apple35. Which of the following shows the development of ideas in this passage?A. B.C. D.CP: Central Point P: Point Sp: Sub-point(次要点) C:Conclusion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。

2017—2018学年第二学期高二级期末考试语文试题第Ⅰ卷阅读题一、现代文阅读(23分)(一)论述类文本阅读(本题共3小题,9分)阅读下面的文字,完成1~3题。
中国传统社会给人两个相互矛盾的印象:一方面,它十分注重平等;另一方面,它又十分注重纲常伦理,表现出严格的等级秩序。
不过,无论如何解释这种印象,它至少说明在中国传统社会中同时存在人与人之间的平等和差异两个问题。
在西方由正义原则加以处理的人与人之间平等与差异的关系问题在中国社会同样存在,而且同样也需要某种协调机制。
概而言之,从功能的角度看,中国传统社会,特别是在儒家思想中,对这一关系的处理,是通过“仁”“礼”“义”三项基本原则彼此支撑、相互为用实现的。
“仁”是对他人之爱,在儒家的价值体系中处于核心地位,所以孔子说:“志士仁人,无求生以害仁,有杀身以成仁。
”“仁”的基础则是对亲人之爱,所谓“仁者人也,亲亲为大”。
孟子进一步指出:“孩提之童,无不知爱其亲者;……亲亲,仁也。
”并且孟子认为,这种爱的基础,是“不忍人之心”,即同情心。
同情即同样的感情,是“人同此心,心同此理”这一心理事实的体现。
因此,“仁”的生发机制,是一个推己及人,由近及远的过程,即把对亲人之爱扩展为对邻人之爱,再扩展到对天下人之爱,也就是孟子所说的:“老吾老,以及人之老;幼吾幼,以及人之幼。
”与“仁”所体现的“合和”精神不同,“礼”强调的是人与人之间尊卑贵贱(纵向)、亲疏厚薄(横向)的差秩格局和纲常秩序,反映“别”与“分”的一面。
“礼”在儒家思想中的重要地位是一个众人皆知的事实,“礼,国之干也。
”“礼”提供了一套基本的政治架构,对中国传统社会的稳定有序具有举足轻重的作用,后者因此也被称为“礼治社会”。
儒家强调“礼”治,但目的不是造成一个等级森严、上下隔阂的社会,而是通过“礼”的规范与约束,实现社会的和谐和睦。
用以平衡“仁”与“礼”的就是“义”的原则。
在中国传统文献中,“义”是一个含义比较丰富的概念。

)(二)文学类文本阅读(本题共3小题,14分)4.B(村民提着东西来陪父亲喝酒并不能说明乡亲们的虚伪、自私。
)5.①一语双关。
XXX家的“传家宝”,表面上指蓑衣、竹篙及渡船,实际上指春子家世代知恩感恩的精神。
②“传家宝”是小说的线索。
整篇小说围绕着父亲期待儿子继承“传家宝”、儿子如何继承“传家宝”展开。
③“传家宝”暗合了小说的主旨。
XXX虽然没有像父辈那样义务摆渡,但却用自己的智慧传承了家族的感恩精神,而这正是XXX家的“传家宝”。
(答出一点给2分,答出两点给4分,答出三点给5分;如答“引起读者兴趣”给1分;如有其他概念,言之成理,也可酌情给分。
)6.①这样安排结尾,既在意料之外,又在情理之中。
小说前半部分写春子“无端的怨恨”“隐隐的不满”以及与父亲的“争吵”,使得小说的结尾出人意料;但另一方面,这样的结尾又照应了上文“春子摆渡收费”,面对村民的假意关心XXX淡淡一笑、毫无失落等情节,给这些情节一个合理的解释,使这个结尾又在情理之中。
②丰富了人物形象。
XXX出资建桥,既不负父亲的期待,报了乡亲们的恩情,又可一劳永逸,方便了乡亲们渡河。
小说塑造了一个孝顺感恩、智慧多能的新时代青年形象。
③深化了小说主旨。
小说结尾通过交代出“春子出资建桥”的事实,不仅赞颂了代代相传的感恩精神,也褒扬了在新的时代、用新的方式解决问题的智慧。

故选C 。
2. 在如图所示的各电场中,a 、b 两点的电场强度相同的是( ) A. B. C. D.【答案】D【解析】【分析】【详解】AB .A 图和B 图中的ab 两点的电场的方向不同,场强大小相等,所以两点的电场强度不相同。
故AB 错误;C .C 图中的ab 两点,b 点的电场线比较密,所以b 点的场强大。
故C 错误;D .D 图中的两点所在的电场为匀强电场,两点的电场强度大小相等,方向相同,场强相同,故D 正确; 故选D 。
【点睛】3. 阻值相等的四个电阻、电容器C 及电池(E 内阻可忽略)连接成如图所示电路.开关S 断开且电流稳定时,C 所带的电荷量为1Q ,闭合开关S ,电流再次稳定后,C 所带的电荷量为21.Q Q 与2Q 的比值为( )A. 25B. 12C. 35D. 23【答案】C【解析】试题分析:根据等效电路,开关S 断开时,电容器的电压12112325+3E U R E R R =⋅⨯=,得11Q CU =;S 闭合时,211123+2E U R E R R =⋅=,22Q CU =,故112235Q U Q U ==,故选C . 【学科网考点定位】闭合电路的欧姆定律、电容器【名师点睛】此题是对闭合电路欧姆定律及电容器问题的考查;解题关键是要搞清电路的结构,画出等效电路图,搞清电容器两端的电压是哪个电阻两端的电压,然后根据Q=CU 求解电容器的带电荷量.4. 在条形磁铁S 极附近,用绝缘轻绳悬挂一轻质圆线圈,磁铁与圆线圈在同一平面内,当线圈中通有逆时针方向电流时,则线圈运动情况( )A. 从上向下看,线圈顺时针旋转,同时靠近S 极B. 从上向下看,线圈顺时针旋转,同时远离S 极C. 从上向下看,线圈逆时针旋转,同时靠近S 极D. 从上向下看,线圈逆时针旋转,同时远离S 极【答案】A【解析】由右手螺旋定则可知,线圈的外面为N 极,里面为S 极;因为异名磁极相互吸引,因此从上往下看,线圈做顺时针方向转动,同时靠近磁铁,故选项A 正确,选项BCD 错误.点睛:此题考查了右手定则和磁极间相互作用的应用,注意线圈产生的磁场与条形磁体产生的磁场很相似,可以利用右手定则判断磁场的N 、S 极.5. 粗细均匀的电阻丝围成的正方形单匝线框置于有界匀强磁场中,磁场方向垂直于线框平面,其边界与正方形线框的边平行.现使线框以同样速率沿四个不同方向匀速移动,如下图所示( )A.

I hurried up during this process.One day, however, while at a party, I heard an artist friend telli ng everybody that his idea came while he was having a show er. “What about you?” he asked, “Don’t you get your creative thoughts from the same place?”“I’m in and out in a hurry,” I told him proudly. “I have no time t o waste!”“What a pity,” he said. “That’s the place where you need to slo w down; plenty of great thoughts come from there!” I tried it o ut. I slowed down the whole process, started enjoying the war m water, taking a little longer to soap myself and even spendi ng more time just enjoying the process, and realized how muc h I had missed in hurrying up all these years.A woman told me how much stress her friend was suffering fr om and how she sought to convince her that she needed to fi nd ways to relax. She gave her a videotape on stress manage ment and relaxation techniques, and encouraged her to watch it right away. Fifteen minutes later, her friend handed back th e tape. “It was g ood,” she said,” but I don’t need it.”“But it’s a 70 - minute video,” the woman replied, “You couldn’t have watched the whole thing.”“Yes, I did,” her friend said. “I put it in fast - forward!”A major social problem of the 21st century is Hurry Sickness. We hurry through work. We swallow fast food. We complain t hat we don’t have enough time. We race through the days an d weeks until one day we look back in amazement and comm ent, “My god, how the years flew by!” Then we realize the heavy price we have paid for traveling fast.Symptoms of Hurry Sickness include stress and anxiety, bad r elationships, lowered work performance and even disease. S ome people don’t survive it. What’s the cure? Slow down, for l ife is so short and precious that we must live it well.4. What was the advantage of taking a shower in the eyes of t he artist friend?A. Time was saved.B. Nothing was missed.C. Great ideas flew away.D. Creative thoughts came.5. What was the trouble with the woman’s friend?A. She felt stressed.B. She found the tape useless.C. She found no way to relax.D. She watched the tape too f ast.6. What are the major trouble people face in the 21st century i n the writer’s eyes?A. People run fast to work.B. Everything is done in a hurry.C. People don’t have enough time.D. Time flies without bei ng noticed.7. How can the problem be settled?A. By pacing down.B. By learning to survive.C. By developing friendship.D. By performing good work.CRegardless of how far we’d like to believe gender(性别) equality in the workplace has come, there’s still a yawning gap between male and female leaders in the professional wo rld. A 2018 statistic shows that women nowadays hold just 5.8 percent of CEOs positions at S&P 500 companies, according to Catalyst.While it’s not a huge shock that women are somewhat underr epresented in leadership positions, what is surprising though, is the fact that females may actually be better suited to lead in almost every area, at least according to new findings from th e BI Norwegian Business School.In their research, Professor Martinsen and Professor Lars Gla s surveyed (调查) 2,900 managers with a special focus on personality types. The results were clear: Women scored higher than men in fo ur of the five major leadership-centric categories.While some people believe that men inherently make better le aders — probably because they picture a leader with a comm anding voice, which is more typical of men than women — thi s piece of research suggests that women are better at method ical management and goal-setting, openness, sociability and supportiveness, as well as a bility to communicate clearly.There was one area in which men scored higher than women, though, and that was on emotional stability and ability to face job-related pressure and stress. The results suggest that women are more sensitive to the effects of high-pressure or highly emotional situations.Obviously, it’s important to consider individual(个人的) differences. Anyone, regardless of gender, may be an ins piring leader and a competent boss. So next time you’re hiring for a management position, you just might want to give the re sumes(简历) from female candidates a harder look.8. What makes us shocked much at leadership positions?A. Women are worse than men.B. Men take almost all high positions.C. There is a huge gap between genders.D. Women might behave better in every field.9. Which of the following can best replace the underlined word ‘‘inherently” in paragraph 4?A. properlyB. potentiallyC. naturallyD. normally10. Which of the following may be the best title of this text?A. How We Can Figure Out The BossB. Why Women Are Better Than MenC. Why Women Make Better BossesD. How We Can Tell Gender Difference11. Who might have special interest in this article?A. Job hunters.B. Employers.C. Employees.D. Univers ity students.DOne of the most striking findings of a newly research in the U K is that of the people interviewed, one in two believes that it i s becoming more difficult to meet someone to start a family wi th.Why are many finding it increasingly difficult to start close rela tionships? Does modern life really make it harder to fall in lov e? Or are we making it harder for ourselves? It is certainly the case today that contemporary couples benefit in different way s from relationships. Women no longer rely upon partners for money or status. A man doesn’t expect his wife to be in sole (唯一的) charge of running his household and raising his children. But perhaps the knowledge that we can live perfectly well with out a partnership means that it takes much more to persuadepeople to abandon their independence.In theory, finding a partner should be much simpler these day s. Only a few generations ago, your choice of soul mate was li mited by geography, social convention and family tradition. Alt hough it was never clear, many marriages were essentially arr anged. Now those barriers have been broken down. You can approach a builder or a brain surgeon in any bar in any city on any given evening. When the world is your oyster (牡蛎), you surely have a better chance of finding a pearl.But it seems that the old conventions have been replaced by t he limitations of choice. The expectations of partners are rais ed to an unmanageable degree: good looks, impressive salar y, kind to grandmother, and right socks. There is no room for error in the first impression.We think that a relationship can be perfect. If it isn’t, it should be ended. We work to protect ourselves against future hearta che and don’t put in the hard emotional labor needed to build a strong relationship. Twelve-hour work at the office makes relaxed after-hours dating difficult. The cost of housing and child-raising creates pressure to have a stable income and career b efore a life partnership.12. What is a contemporary family like in UK today?A. Couples share the burdens.B. Men begin to depend on women.C. Women are responsible for housework.D. It is difficult to take care of a family.13. Why do people preserve their independence?A. To live alone happily.B. To have more choices.C. To avoid marriages.D. To ignore traditions.14. What makes it hard for people to date?A. Mental headache in dating.B. The pressure to survive.C. Bad luck in finding a partner.D. The faith between life pa rtners.15. What is the author trying to inform us in this text?A. Perfect marriages conflict with independence.B. People should, spend more money on marriages.C. The expectations and reality separate the lovers.D. Independence is much more important than love.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。
