in this section, you are going to read a passage with ten statements attached to it. each statement contains information given in one of the paragraphs. identify the paragraph from which the information is derived. you may choose a paragraph more than once. each paragraph is marked with a letter. answer the questions by marking the corresponding letter on answer sheet 2.why lifelong learning is the international passport to successa) picture yourself at a college graduation day, with a fresh cohort(一群) of students about to set sail for new horizons. what are they thinking while they throw their caps in the air? what is it with this thin sheet of paperthat makes it so precious? it’s not only the proof of acquired knowledge but plays into the reputation game of where you were trained. being a graduatefrom harvard law school carries that extra glamour, doesn’t it? yet take a closer look, and the diploma is the perfect ending to the modern tragedy of education.b) why? because universities and curricula are designed along the three unities of french classical tragedy: time, action, and place. students meet at the university campus (unity of place) for classes (unity of action) duringtheir 20s (unity of time). this classical model has traditionally produced prestigious universities, but it is now challenged by the digitalisation of society—which allows everybody who is connected to the internet to access learning—and by the need to acquire skills in step with a fast-changing world. u niversities must realise that learning in your 20s won’t be enough. if technological diffusion and implementation develop faster, workers will haveto constantly refresh their skills.c) the university model needs to evolve. it must equip students with the right skills and knowledge to compete in a world ‘where value will be derived largely from human interaction and the ability to invent and interpret things that machines cannot’, as the english futurist richard watson puts it. by teaching foundational knowledge and up-to-date skills, universities willprovide students with the future-proof skills of lifelong learning, not justget them ‘job-ready’.d) some universities already play a critical role in lifelong learning as they want to keep the value of their diplomas. this new role comes with a huge set of challenges, and needs largely to be invented. one way to start this transformation process could be to go beyond the ‘five-year diploma model’to adapt curricula to lifelong learning. we call this model the lifelong passport.e) the bachelor’s degree could be your passport to lifelong learning. for the first few years, students would ‘learn to learn’and get endowed with reasoning skills that remain with them for the rest of their lives. for instance, physics allows you to observe and rationalise the world, but also to integrate observations into models and, sometimes, models into theories orlaws that can be used to make predictions. mathematics is the language used to formulate the laws of physics or economy, and to make rigorous computations that turn into predictions. these two disciplines naturally form the foundational pillars of education in technical universities.f) recent advances in computational methods and data science push us into rethinking science and engineering. computers increasingly become principal actors in leveraging data to formulate questions,which requires radically new ways of reasoning. therefore, a new discipline blending computer science, programming, statistics and machine learning should be added to thetraditional foundational topics of mathematics and physics. these threepillars would allow you to keep learning complex technical subjects all your life because numeracy(计算) is the foundation upon which everything else is eventually built.g) according to this new model, the master of science (msc) would become the first stamp in the lifelong learning journey. the msc curriculum should prepare students for their professional career by allowing them to focus on acquiring practical skills through projects.h) those projects are then interwoven with fast-paced technical modules(模块)learned ‘on-the-fly’and ‘at will’ depending on the nature of the project. if, for instance, your project is developing an integrated circuit, you will have to take a module on advanced concepts in microelectronics. the most critical skills will be developed before the project even starts, in the form of boot camps (短期强化训练), while the rest can be fostered along with the project, putting them to immediate use and thus providing a rich learning context.i) in addition to technical capabilities, the very nature of projects develops social and entrepreneurial skills, such as design thinking,initiative taking, team leading, activity reporting or resource planning. not only will those skills be actually integrated into the curriculum but theywill be very important to have in the future because they are difficult to automate.j) after the msc diploma is earned, there would be many more stamps of lifelong learning over the years. if universities decide to engage in this learning model, they will have to cope with many organisational challengesthat might shake their unity of place and action. first, the number of students would be unpredic table. if all of a university’s alumni (往届毕业生)were to become students again, the student body would be much bigger than itis now, and it could become unsustainable for the campus in terms of both size and resources. second, freshly graduated students would mix withprofessionally experienced ones. this would change the classroom dynamics, perhaps for the best. project-based learning with a mixed team reflects the reality of the professional world and could therefore be a better preparation for it.k) sound like science fiction? in many countries, part-time studying is not exceptional: on average across oecd countries, part-time students in represented 20 per cent of enrolment in tertiary education. in many countries, this share is higher and can exceed 40 per cent in australia, new zealand and sweden.l) if lifelong learning were to become a priority and the new norm, diplomas, just like passports, could be revalidated periodically. a time-determined revalidation would ease administration for everybody. universities as well as employers and employees would know when they have to retrain. for instance, graduates from the year would have to come back in .m) this could fix the main organisational challenges for the university, but not for the learners, due to lack of time, family obligations or funds. here, online learning might be an option because it allows you to save your‘travel time’, but it has its limits. so far, none of the major employers associated with online learning platforms such as coursera and udacity has committed to hire or even interview graduates of their new online programmes.n) even if time were not an issue, who will pay for lifelong learning? that’s the eternal debate: should it be the learner’s responsibility, that of his employer, or of the state? for example, in massachusetts, the healthcare professions require continuing education credits, which are carefully evidenced and documented. yet the same state’s lawyers don’t require continuing legal education, although most lawyers do participate in it informally. one explanation is that technology is less of a factor in law than it is in healthcare.o) europe has many scenarios, but the french and swiss ones areinteresting to compare. in france, every individual has a right to lifelong learning organised via a personal learning account that is credited as you work. in switzerland, lifelong learning is a personal responsibility and not agovernment one. however, employers and the state encourage continuing education either by funding parts of it or by allowing employees to attend it.p) universities have a fundamental role to play in this journey, andhigher education is in for a change. just like classical theatre, the old university model produced talent and value for society. we are not advocating its abolition but rather calling for the adaptation of its characteristics to meet the needs of today.36. students should develop the key skills before they start a project.37. by acquiring reasoning skills in the first few years of college, students can lay a foundation for lifelong learning.38. the easy access to learning and rapid technological changes have brought the traditional model of education under challenge.39. unbelievable as it may seem, part-time students constitute a considerable portion of the student body in many universities across the world.40. some social and managerial skills, which are not easily automated,will be of great importance t o students’future careers.41. a new model of college education should provide students with the knowledge and skills that will make them more inventive and capable oflifelong learning.42. a mixed student body may change the classroom dynamics and benefit learning.43. the question of who will bear the cost of lifelong learning is a topic of constant debate.44. to the traditional subjects of math and physics should be added a new discipline which combines computer science with statistics and other components.45. students who are burdened with family duties might choose to take online courses.section cdirections: there are 2 passages in this section. each passage is followed by some questions or unfinished statements. for each of them there are fourchoices marked a), b), c) and d). you should decide on the best choice andmark the corresponding letter on answer sheet 2with a single line through the centre.passage onequestions 46 to 50 are based on the following passage.why does social media trigger feelings of loneliness and inadequacy? because instead of being real life, it is, for the most part, impression management, a way of marketing yourself, carefully choosing and filtering the pictures and words to put your best face forward.online “friends” made through social media do not follow the normal psychological progression of an interpersonal relationship. you share neither physical time nor emotional conversations over the internet. you simply communicate photographs and catchy posts to a diverse group of people whom you have “friended” or “followed” based on an accidental inter action. this isnot to say that your social media friends can’t be real friends. theyabsolutely can, but the two are not synonymous. generally speaking, there areno unfiltered comments or casually taken photos on our social media pages. and, rightfully s o, because it wouldn’t feel safe to be completely authentic and vulnerable with some of our “friends” whom we don’t actually know or with whom trust has yet to be built.social media can certainly be an escape from the daily grind, but we mustbe cauti oned against the negative effects, such as addiction, on a person’s overall psychological well-being.as humans, we yearn for social connection. scrolling (滚动) through pagesof pictures and comments, however, does not provide the same degree offulfill ment as face to face interactions do. also, we tend to idealize others’ lives and compare our downfalls to their greatest accomplishments, ending in feelings of loneliness and inadequacy.social media can lead people on the unhealthy quest for perfection. some people begin to attend certain events or travel to different places so thatthey can snap that “perfect” photo. they begin to seek validation throughthe number of people who “like” their posts. in order for it to play a psychologically healthy role in your social life, social media should supplement an already healthy social network. pictures and posts should be byproducts of life’s treasured moments and fun times, not the planned andcalculated image that one is putting out into cyberspace in an attempt to fill insecurities or unmet needs.ultimately, social media has increased our ability to connect with various types of people all over the globe. it has opened doors for businesses and allowed us to stay connected to people whom we may not otherwise get to follow. however, social media should feel like a fun experience, not one that contributes to negative thoughts and feelings. if the latter is the case, increasing face-to-face time with trusted friends, and minimizing timescrolling online, will prove to be a reminder that your social network is much more rewarding than any “like,” “follow” or “share” can be.46. what does the author imply social media may do to our life?a) it may facilitate our interpersonal relationships.b) it may filter our negative impressions of others.c) it may make us feel isolated and incompetent.d) it may render us vulnerable and inauthentic.47. why do people post comments selectively on social media?a) they do not find all their online friends trustworthy.b) they want to avoid offending any of their audience.c) they do not want to lose their followers.d) they are eager to boost their popularity.48. what are humans inclined to do according to the passage?a) exa ggerate their life’s accomplishments.b) strive for perfection regardless of the cost.c) paint a rosy picture of other people’s lives.d) learn lessons from other people’s downfalls.49. what is the author’s view of pictures and posts on s ocial media?a) they should record the memorable moments in

for perfection.50. what does the author advise people to do when they find their online experience unconstructive?a) use social media to increase their ability to connect with various types of

real-life friends instead of caring about their online image.passage twoquestions 51 to 55 are based on the following passage.imagine that an alien species landed on earth and, through their mere presence, those aliens caused our art to vanish, our music to homogenize, and our technological know-how to disappear. that is effectively what humans have been doing to our closest relatives—chimps (大猩猩) .back in , a team of scientists led by andrew whiten showed that chimps from different parts of africa behave very differently from one another. some groups would get each other’s attention by rapping branches with their knuckles(指关节), while others did it by loudly ripping leaves with their teeth. the team identified 39 of these traditions that are practiced by some communities but not others—a pattern that, at the time, hadn’t been seen in any animal except humans. it was evidence, the team said, that chimps have their own cultures.it took a long time to convince skeptics that such cultures exist, but now we have plenty of examples of animals learning local traditions from one another.but just when many scientists have come to accept the existence of animal cultures, many of those cultures might vanish. ammie kalan and her colleagues have shown, through years of intensive fieldwork, that the very presence ofhumans has eroded the diversity of chimp behavior. where we flourish, their cultures wither. it is a bitterly ironic thing to learn on the 20thanniversary of whiten’s classic study.“it’s amazing to think that just 60 years ago, we knew next to nothingof the behavior of our sister species in the wild,”whiten says. “but now,just as we are truly getting to know our primate(灵长类) cousins, the actionsof humans are closing the window on all we have discovered.”“sometimes in the rush to conserve the species, i think we forget aboutthe individuals,” says cat hobaiter, a professor at the university of st. andrews. “each population, each community, even each generation of chimps is unique. an event might only have a small impact on the total population of chimps, but it may wipe out an entire community—an entire culture. no matter what we do to restore habitat or support population growth, we may never beable to restore that culture.”no one knows whether the destruction of chimp culture is getting worse.few places have tracked chimp behavior over long periods, and those that haveare also more likely to have protected their animals from human influence.obviously conservationists need to think about saving species in a completely new way—by preserving animal traditions as well as bodies and genes. “instead of focusing only on the c onservation of genetically based entities like species, we now need to also consider culturally based entities,” says andrew whiten.51. what does the author say we humans have been doing to chimps?a) ruining their culture.b) accelerating their extinction.c) treating them as alien species.d) homogenizing their living habits.52. what is the finding of andrew whiten’s team?a) chimps demonstrate highly developed skills of communication.b) chimps rely heavily upon their body language to communicate.c) chimps behave in ways quite similar to those of human beings.d) different chimp groups differ in their way of communication.53. what did ammie kalan and her colleagues find through their intensive fieldwork?a) whiten’s classic study has little impact on the diversity of chimp behavior.b) chimp behavior becomes less varied with the increase of human activity.c) chimps alter their culture to quickly adapt to the changed environment.d) it might already be too late to prevent animal cultures from extinction.54. what does cat hobaiter think we should do for chimp conservation?a) try to understand our sister species’ behavior in the wild.b) make efforts to preserve each individual chimp community.c) study the unique characteristics of each generation of chimps.d) endeavor to restore chimp habitats to expand its total population.55. what does the author suggest conservationists do?a) focus entirely on culturally-based entities rather than genetically-based ones.b) place more stress on animal traditions than on their physical conservation.c) conserve animal species in a novel and all-round way.d) explore the cultures of species, before they vanish.part iv translation

长江和黄河虽然同为中华文化的母亲河，都取得了辉煌灿烂的成果，但从夏商周到西晋末，黄河流域经济文化发展水平超过长江流域。
然而，自东汉末年以来，中国北方多次遭到游牧民族的冲击，历次兵燹带来大规模北人南迁，而相对安定的长江流域随着生产力的发展和技术的进步，优越的自然条件日益凸显。
长江流域和黄河流域皆具水热条件，故成为中华文化的两大源头，而长江流域拥有更丰沛的水热资源。
但在原始社会末期至商末这一文明初始阶段的气候条件下，中国先民所能达到的生产力水平更适合开发北方黄河流域。
在全新世中期，全球气候变暖，长江、黄河流域较之现在更加温暖湿润。
黄河流域森林密布，受低温和干旱的威胁较轻;而气候炎热潮湿的长江流域则经常发生洪涝灾害。
当时的原始农业以木石农具为主，黄河中上游的粟作农业依托肥沃疏松的黄土和黄河及其大小支流的灌溉，通过精耕细作实现了蓬勃发展，各早期文明也借此绵延不绝并逐渐融合;而长江流域则因其红壤的土质较为紧密，水稻种植所需平整土地及引水灌溉的劳动量大、技术要求高，而当时人员、技术所能达到的稻作生产方式又较为粗放，且常受洪水威胁，故其农业产出量不及黄河流域。

一、现代文阅读(34分)(一)现代文阅读Ⅰ(本题共5小题，18分)阅读下面的文字，完成1~5题。
材料一：①近年来，人工智能技术与人文历史研究碰撞出不少火花，那么，AI对于古代汉语的理解能力怎么样?②日前，北京师范大学中文信息处理与古典文献学专业的研究者们尝试训练一个“饱读诗书”的语言模型，并让AI来参与古籍整理的工作。
模型学习的对象包括《四库全书》与“殆知阁”语料库，而学习的方法则来自语言智能领域最新的深层语言模型。
③2018年，谷歌公司曾推出了深层语言模型BERT，它在阅读理解等11项语言理解任务中刷新纪录。
和之前的方法相比，深层语言模型一是可以吞吐超大量的数据，二是有很强的记忆和理解能力。
现有的深层语言模型覆盖了英文和中文，但却不具备理解古汉语的能力。
于是，研究者们希望通过上述海量的古汉语数据来让机器“感受”一下博大精深的诗书礼乐文化。
在多块计算卡上并行训练了约一周时间后，古汉语BERT初出江湖，AI可以像人一样联系上下文理解字词含义，并将其以数学向量表示。
④为了检测其理解效果，研究者们引入了句读任务。
在古典文史学习过程中，句读通常是必备的基本功。
古文句读不仅需要考虑当前文本的语义和语境信息，还需要综合历史文化常识，对古汉语知识有较高要求。
宋代大儒朱熹读韩愈文章，便有“然不知此句当如何读”之惑。
在句读的过程中，有三项重要的技能点：利用古汉语特有的节奏和韵律感，联系上下文语境信息推敲求解，调用文本之外的历史文化知识。
