2020-2021学年北京市第五十五中学高三语文上学期期中试卷及答案一、现代文阅读（36分）(一)现代文阅读I(9分)阅读下面的文字，完成下面小题。

材料一：“复兴号”是我国具有完全自主知识产权的中国标准动车组。

目前，“复兴号”中国标准动车组有“CR400AF”和“CR400BF”两种型号。

按照中国铁路总公司新的动车组编制规则，新型自主化动车组均采用“CR”开头的型号，“CR”是中国铁路总公司英文缩写，也是指覆盖不同速度等级的中国标准动车组系列化产品平台。

型号中的“400”为速度等级代码，代表该型动车组试验速度可达400km/h及以上，持续运行速度为350km/h。

“A”和“B”为企业标识代码，代表生产厂家；“F”为技术类型代码，红色的是中车四方的AF，黄色的是中车长客的BF。

今后，中国铁路总公司将根据运输市场需求，逐步研发CR300和CR200系列中国标准动车组。

作为中国最新一代的标准动车组，“复兴号”真正实现了从“洋基因”到“纯中国”的转变。

在高速动车组254项重要标准中，中国标准占84%，中国标准动车组整体设计以及车体、转向架、牵引、制动、网络等关键技术都是我国自主研发，因此，具有完全自主知识产权。

与“和谐号”相比，“复兴号”整车性能指标实现较大提升。

“复兴号”“寿命”更长，它的设计寿命达到了30年，而“和谐号”是20年。

“身材”更好，采用全新低阻力流线型头型和车体平顺化设计，车型看起来线条更优雅，“和谐号”动车组车顶有一个“鼓包”（受电弓和空调系统）。

“复兴号”把这个“鼓包”下沉到了车顶下的风道系统中。

“容量”更大，列车高度从3700毫米增高到了4050毫米，座位间距更宽敞。

舒适度更高，“复兴号”空调系统充分考虑减小车外压力波的影响，通过隧道或交会时减小耳部不适感，列车设有多种照明控制模式。

车厢内实现了WiFi网络全覆盖。

（摘编自《中国高铁大揭秘，“复兴号”来了！》《人民日报》）材料二：中国目前已经成功拥有世界先进的高铁集成技术、施工技术、装备制造技术和运营管理技术，具有组团出海的实力，可以挑战任何竞争对手。

Someone spotted the large whale on the Prince of Wales Island near the coast of British Columbia on the morning of July 29th. The Coast Guard was called around 9 a.m. local time. Chance Strickland, the captain of a private yacht in Alaska, and his crew anchored and began life-saving action that were videoed by Aroon Melane and posted on the Internet.Strickland could hear the orca calling out to killer whales swimming in the area. People on other boats stopped with water and buckets to pour water over the animal. “There were tears coming out of its eyes,” Mr. Strickland told the local newspaper. “It was pretty sad.”The group of people formed a chain that passed buckets of seawater back and forth and poured the water on the orca, which seemed to liven it up. It made a noise and raised its tail when it got water.The National Oceanic and Atmospheric Administration (NOAA) was called in, which can be seen on the video using a machine to spray amist of seawater on the orca, which doubled as a way to keep the whale cool and scare the large group of birds that were hoping to feast on the beast.Melane said in her video that the orca was stranded (搁浅) for about six hours until the tide came inandswept it back into the ocean. The group efforts of Strickland’s crew and the NOAA saved the 13-year-old killer whale.4. Why did birds circle above the orca?A. They were eager to eat it.B. They wished to protect it.C.

Animals and Humans UnitedCWe have most friends at the age of 26 afterhaving spent the first quarter of our lives building up our friendship circle, new research has claimed.The research into friendship shows that our social circle peaks at 26 years and 7 months, at which we typically have five close friends. Women are most popular at 25 years and 10 months, with men hitting the highest friendship point a little later at 27 years and 3 months.The research, by Forever Friends, shows that about a third of adults meet their closest friends while at school, with about a fifth saying they meet them at work.Social networks such as Facebook and Twitter now also play a major role in building new friendship. The research points out that 25 to 34-year-olds make 22 friends via Facebook, compared to 18 to 24-year-olds who make 12, and 35 to 44-year-olds who make just four.Forever Friends' relationship coach Sam Owen says, “It is no coincidence that over a third of us meet our best friends at school. It is a key time in our lives when friendship is growing through sharing notes, giving gifts, seeing each other regularly and laughing a lot. As adults we can often forget how powerful these small things are and how the little things can make a difference."Later in life we find ourselves losing friends. Over half of us lose friendship through moving, while 36% saythat over time they grow apart from close pals. Having children also causes 19% todrift away fromchildhood friends.With growing pressure being put on friendship these days, it's important to make time for our friendship.8. How many friends can a 20-year-old college student make via Facebook?A. 22.B. 18.C. 12.D. 4.9. In Paragraph 5, the author is trying to tell the readers ________.A. how important making friends isB. school time is an important period to develop friendshipC. how much has been done to keep friendshipD. that friendship is not easy to keep10. The underlined phrase "drift away from" in Paragraph 6 means ________.A. make sense ofB. make up withC. feel sorry forD. lose touch with11. This passage is mostprobably taken from ________.A. a newspaperB. an advertisementC. a textbookD. Facebook or TwitterDImust have always known reading was very important because the first memories I have as a child deal with books. There was not one night that I don’t remember mom reading me a storybook by my bedside. I was extremely inspired by the wonderful way the words sounded.I always wanted to know what my mom was reading. Hearing mom say, “I can’t believe what’s printed in the newspaper this morning,” made me want to grab it out of her hands and read it myself. I wanted to be like my mom and know all of the things she knew. So I carried around a book, and each night, just to be like her, I would pretend to be reading.This is how everyone learned to read. We would start off with sentences, then paragraphs, and then stories. It seemed an unending journey, but even as a six-year-old girl I realized that knowing how to read could open many doors. When mom said, “The C-A-N-D-Y is hidden on the top shelf,” I knew where the candy was. My progress in reading raised my curiosity, and I wanted to know everything. I often found myself telling my mom to drive more slowly, so that I could read all of the road signs we passed.Most of my reading through primary, middle and high school was factual reading. I read for knowledge, and to make A’s on my tests. Sometimes, I would read a novel that was assigned, but I didn’t enjoy this type of reading.I liked facts, things that are concrete. I thought anything abstract left too much room for argument.Now that I’m growing and the world I once knew as being so simple is becoming more complex, I find myself needing a way to escape. By opening a novel, I can leave behind my burdens and enter into a wonderful and mysterious world where I am now a new character. In these worlds I can become anyone. I don’t have to write down what happened or what technique the author was using when he or she wrote this. I just read to relax.We’re taught to read because it’s necessary for much of human understanding. Reading is an important part of my life. Reading satisfies my desire to keep learning. And I’ve found that the possibilities that lie within books are limitless.12. Why did the author want to grab the newspaper out of mom’s hands？A. She wanted mom to read the news to her.B. She couldn’t wait to tear the newspaper apart.C. She couldn’t help but stopmom from reading.D. She was eager to know what had happened.13. According to Paragraph 3, the author’s reading of road signs shows___________.A. her own way to find herselfB. her eagerness to develop her reading abilityC. her growing desire to know the world around herD. her effort to remind mom to obey traffic rules14. The author takes novel reading as a way to___________.A. explore a mysterious landB. develop an interest in learningC. get away from a confusing worldD. learn about the adult world15. What could be the best title for the passage？A The Pleasure of Reading B. Growing Up with ReadingC. The Magic of ReadingD. Reading Makes a Full Man第二节（共5小题；每小题2分，满分10分）阅读下面短文，从短文后的选项中选出可以填入空白处的最佳选项。

近代中国从天圆地方“天下”进入地球“天下”以来，传入了西方“人性恶”的人类哲学思想，以及与之相匹配的遏制“性恶”的国家行政观念：因为人性本源是恶的，因此必须配之以“法律面前人人平等”的国家制度。

这种关于“人性恶”的人类哲学观点，中国其实在春秋战国时代早已有之，代表人物便是诸子百家之一的荀子。

荀子持“人性恶”观点，而同时代的孟子则持“人性善”的观点。

中国古代历史的各种哲学流派，有一个非常奇特的现象。

按故往历史中国十分惯常思维的“大是大非”原则来看，人性的善与恶，是两个绝然相反的人类社会哲学元素，荀子与孟子应被归为两个不同的学说流派。

但中国流传至今的传统学术却把两位持泾渭分明哲学观点的人，同称为“儒家”。

不知两位已作古二千多年的大学者会不会在黄土之下跃骨而起？仔细想来，把不同哲学流派的学者们归于“一家”的文化现象，也在中国古代历史的发展情理之中。

中国数千年实行的是皇权行政一统论，而与行政一统论相匹配的学术一元论，也就不得不把为华夏人类思想作出过杰出贡献的各流派人物都归入相同的彀中。

在归入“一家”之后，再予以分门别类，作内部清算，谓之“一家”之内的不同“路线斗争”，再或逐“师门”，斥之学术叛徙、学术内奸。

那个时代的这种学术的历史发展逻辑，同样与封建社会一统皇权独裁之下的“羁縻”臣僚、清算各派臣僚的行政制度，完全匹配。

但显然，两者本来就不在一个学术流派中，而这正是符合近代以来人们认同的人类历史“学术多元论”观点的。

历史地看，皇朝社会恶劣的一元论阻碍了古代中国社会分科学说的产生，从而使古旧读书做官的儒学成为通向文化一元论的单行线和独木桥，但人类思想（包括经济形态）本质的多样性决定了学术的“多元”，何必纳入一家？它实质是泯灭了自古以来中华文化哲学思想的丰富多彩性。

春秋末期，早于荀子孟子一百年的孔子仅谈到了人类哲学“仁”的思想，而荀孟则开始了人性恶和人性善的争论。

2021届北京市第五十五中学高三语文上学期期中考试试卷及答案解析一、现代文阅读（36分）(一)现代文阅读I(9分)阅读下面文字，完成下面小题。

材料一：多数消费者还比较狭隘地认为，新能源汽车就是纯电动汽车。

那么究竟什么是新能源汽车呢?新能源汽车是指采用非传统燃料作为动力源的汽车，汽油、柴油和天然气、乙醇等均属于传统燃料。

纯电动汽车、插电混合动力汽车和燃料电池汽车统称为新能源汽车。

这里需要特别指出，常规的混合动力汽车，也就是行业所称的HEV，不属于新能源汽车，因为传统燃料仍是其动力唯一来源。

近日，汽车行业一家知名咨询机构，发起了一项名为“消费者对新能源汽车发展趋势看法”的调研。

调研结果显示：58％的消费者看好插电混动汽车；而正如火如荼的纯电动汽车，发展趋势竟然不如还处在萌芽期的燃料电池汽车。

其实，不管看好哪种动力系统，消费者对新能源汽车接受度不断提高是毋庸置疑的。

2012年，我国新能源汽车产销仅为1万辆，时隔6年后的2018年，成功突破120万辆，我国成为全球最大的新能源汽车消费市场。

当然，其快速发展不仅是需求所致，还受到国家政策和厂商产品供给的影响。

其中，政策对纯电动汽车的发展起到了至关重要的作用。

撇开补贴政策不谈，地方政府对纯电动汽车发展的支持尤为明显。

近日，昆明发布公告：自2019牟1月1日起，昆明新增网约车必须是纯电动汽车，否则不予发放营运证。

有这样规定的省市比比皆是，即使广州、深圳等一线城市也是如此。

(摘编自《畅所欲言：纯电动、插电混动、燃料电池，谁将主导汽车的未来?》，易车网2019年2月20日)材料二：记者从国家市场监督管理总局获悉，国家市场监督管理总局、国家标准化管理委员会批准发布了《电动汽车能量消耗率限值》等国家标准。

《电动汽车能量消耗率限值》标准是全球首个针对纯电动汽车能耗指标提出要求的技术标准。

《电动汽车能量消耗率限值》将在促进纯电动汽车节能技术应用、推动电动汽车降低能耗、节约电力能源方面发挥重要作用，有利于促进新能源汽车产业健康发展。

2021年北京市第五十五中学高三英语上学期期中考试试题及答案第一部分阅读（共两节，满分40分）第一节（共15小题；每小题2分，满分30分）阅读下列短文，从每题所给的A、B、C、D四个选项中选出最佳选项AA 21-year-old female student has become the youngest womanever to be elected as Mayor (市长) after first entering politics to campaign about food.Labor Party (工党) member Rosie Corrigan was elected as Mayor of Selby a market town in North Yorkshire, on Monday. The student’s election was unchallenged to the mayoralty, following a year serving as deputy mayor. Corrigan has just finished her second year studying politics at theUniversityofHull. A political activist since secondary school, lifelong Selby citizen Corrigan has always been ambitious. As a member of the UK Youth Parliament, she co-founded the Selby Youth council, and then went on to run for and win the local council election as a Labour candidate (候选人) aged just 18.Corrigan plan to use her year in office to further encourage political awareness in the youth of Selby. By breaking a political record of being the youngest woman ever elected inUKhistory, Corrigan hopes this will break the misunderstanding of Selby being a sleepy town with old-fashioned views. “It’s an honor to be the Mayor of my lovely hometown,” Corrigan told a newspaper. “I plan on using the year to encourage children and young people to champion their communities.”The politics student’s election has been supported whole heartedly by the politicians she has worked with throughout her early-developing career, including thebackingof former deputy Prime Minister (副首相) John Prescott. Simon Darvill said in an interview, “I hope that the success of Rosie and others like her encourages more young people to get involved in politics and change where they live for the better.”1. Which statement is true according to Paragraph 2?A. Corrigan is new to the political scene of Selby.B. Corrigan became interested in politics in childhood.C. Corrigan has been living in Selby since she was born.D. Corrigan founded the Selby Youth council by herself.2. What can we infer from Paragraph 3?A. Corrigan plans to further her time in office by at least a year.B. The people of Selby are passive and have out-of-date views.C. Corrigan is the youngest person ever elected inUKhistory.D. Corrigan intends to increase Selby’s youth’spolitical involvement.3. Which of the following can replace the underlined word “backing” in Paragraph 4?A. ApprovalB. AppreciationC. PraiseD. SupportBIt’s become an accepted part of keeping up to date with extended family and friends, but if schoolchildren were in their parents’ shoes, the majority wouldn’t share posts of their sons and daughters online. Over 55% said they would not upload news about, or images of, their children to their social media feeds, according to survey of over 16,000 pupils by Votes for Schools.While some were concerned about being embarrassed or the longevity of content which could remain online indefinitely, others expressed concern about their personal data beingcompromised. One of the pupils surveyed said, “Although our parents mean well, sometimes theconsequenceof a post can be disastrous.”In response to thesurvey, children’s mental health charity Place2Be and law firm Mishcon de Reya have produced three films ahead of the Christmas holidays – the best period for parental oversharing.In one video, about safety online, 10-year-old Adavan said, “If you share anything with your family, you know who’s going to see it. But if you share it publicly, there are millions of people who can see your picture.”Joe Hancock, a security lead at Mishcon de Reya, encouraged parents to share wisely. “Simple steps, such as checking your privacy settings and asking others not to share content of your children on their accounts if they have not updated their privacy settings, are a good start. And, as we found out from the children during filming, having their permission is key,” he said.The study marks a shift away from the usual debate about teaching children to use the Internet safely. Sandra Davis, head of the law firm’s family department, said, “Children are the experts on the real and immediate impact of sharenting（晒娃）– the full extent of which we cannot know yet. We must ensure we listen to children and take their views into consideration now in order to avoid any unintendedconsequences further down the line.”4.What’s most pupils’ attitude towards sharing posts about children?A. Skeptical.B. Unconcerned.C. Tolerant.D. Unwilling.5.What does the author intend to do in Paragraph 2?A. Summarize the previous paragraph.B. Provide some advice for parents.C. Predict the consequence of sharing posts.D. Give reasons for the result of the survey.6.What should parents first pay attention to according to Joe Hancock?A. Safety.B. Consequence.C. Wisdom.D. Health.7.What can we learn from the last paragraph?A. Parents should take children’s opinions into account.B. Parents should teach children to use the Internet safely.C. Children must make sure to listen to their parents.D. Children should avoid unintended consequences of sharenting.CThe first patient who died on my watch was an older man with a faulty heart. We tried to slow it down with treatment, but it suddenly stopped beating completely. Later, whenever I would have a case like that one, I found myself second-guessing my clinical management. However, it turns out that thinking twice may actually cause more harm than good.In a working paper, Emory University researchers found that when doctors delivering a baby have a bad result, they are more likely to switch to a different delivery method with the next patient, often unnecessarily and sometimes with worse results.Because doctors make so many decisions that have serious consequences, thefalloutfrom second-guessing appears especially large for us. A 2006 study found that if a patient had a bleed after being prescribed (开药) warfarin, the physician was about 20% less likely to prescribe later patients the blood thinner that prevents strokes (中风). However, if a patient was not on warfarin and had a stroke physicians were still no more likely to prescribe warfarin to their other patients.These findings highlight interesting behavioral patterns in doctors. In the blood-thinner study, doctors were more affected by the act of doing harm (prescribing a blood thinner that ended up hurting doctors were more affected by the act of doing harm(prescribing a blood thinner that ended up hurting a patient) and less affected by letting harm happen (not prescribing a blood thinner and the patient having a stroke). Yet a stroke is often more permanent and damaging than a bleed.But this phenomenon is not unique to medicine. ''Overreaction to Fearsome Risks'' holds true for broader society.For instance, sensational headlines about shark attacks on humans in Florida in 2001 caused a panic and ledthe state to prohibit shark-feeding expeditions. Yet shark attacks had actually fallen that year and, according to the study, such a change was probably unnecessary given the extremely small risk of such an attack happening.Humans are likely to be influenced by emotional and often irrational (不理性的) thinking when processing information, bad events and mistakes. As much as we don't want to cause an unfortunate event to happen again, we need to be aware that a worst situation that can be imagined doesn't necessarily mean we did anything wrong. When we overthink, we fail to rely on thinking based on what we know or have experienced. Instead, we may involuntarily overanalyze and come to the wrong conclusion.I have treated dozens of patients who presented with the same illnesses as my first patient, who died more than a year ago. Instead of second-guessing myself, I trusted my clinical instinct (本能) and stayed the course. Every one of those patients survived. You should trust your instinct in your life, too.8. The first two paragraphs suggest that________.A. bad medical outcomes affect doctorsB delivering babies can be difficult workC. some doctors are not very experiencedD. doctors sometimes make silly mistakes9. In the blood-thinner study, doctors________.A. tend to prescribe less effective medicineB. are more concerned about the patients' safetyC. become less confident in writing a prescriptionD. believe a stroke is more treatable than a bleeding10. What does the underlined word ''fallout'' in Paragraph 3 probably mean?A. ResultB. BenefitC. DifferenceD. Absence11. The author will probably agree that________.A. we should not doubt our own decisionsB. our experience will pave way for our futureC. humans are emotional and irrational on the wholeD. instincts don't necessarily lead to wrong directionsDUK physicist Isaac Newton once said, ''Nature is pleased with simplicity and nature is no dummy (傻子). '' Indeed, Mother Nature can provide almost everything human beings need if we follow her rules. But if we breakthe rules, she is likely to be cruel andlash out at us.The outbreak of the novel coronavirus pneumonia (新型冠状病毒肺炎, NCP) in China and some other countries at the beginning of this year is an example. According to Xinhua News Agency, the new coronavirus is similar to a virus found in a bat in 2017 and probably has an intermediate host (中间宿主). It's believed that the virus originated from the Huanan Seafood Market in Wuhan, Hubei province, where live wild animals were sold.The Wall Street Journal reported that Dr Peter Daszak, president of the US-based health organization EcoHealth Alliance, said, ''This outbreak is a lesson for us. On a global scale, human population density, wildlife diversity, and land use change are what drive new pandemics (流行病). ''In ancient times, people needed to rely on nature to survive so they held it in awe (敬畏). For example, the American Indians believed that humans are a part of nature and nature is a part of humans. Chinese ancients always pursued the harmony between nature and human beings.However, as human beings master more knowledge and make more advanced tools, people try to change and even conquer nature. They use more land to make buildings, genetically modify (改变) plants, capture some wild and rare animals to suit their own needs. In this process, humans gradually lose contact with nature and even throw it out of balance. For example, cutting a large number of forests means carbon dioxide must build up in the atmosphere and it contributes to global warming.Although we don't know for sure what first caused the NCP outbreak, Brian Lamacraft at Medium said it's time for people to ''reflect on our relationship with our planet'' and ''reconnect with this world and everything that we've been given''. After all, according to US poet Gary Snyder, ''Nature is not the place to visit. It's our home. ''12. What does the phrase ''lash out at'' in Paragraph 1 probably mean?A. punishB. controlC. testD. challenge13. What lesson did Daszak think human beings should learn from the NCP outbreak?A. Bats are one of the most dangerous wild animals.B. It's impossible to prevent new pandemics globally.C. We should stop the wildlife trade around the world.D. Humans should live peacefully with nature.14. What is the main idea of Paragraph 5?A. How human beings become their own masters.B. How human activities cause global warming.C. How human beings break the balance of nature.D. How humans use technology to improve their lives.15. What is the author's purpose in writing this article?A. To reflect on the NCP outbreak.B. To explain what led to the NCP outbreak.C. To describe experts' predictions on new pandemics.D. To compare ancient and modern attitudes toward nature.第二节（共5小题；每小题2分，满分10分）阅读下面短文，从短文后的选项中选出可以填入空白处的最佳选项。
