一、现代文阅读〔36分〕〔一〕阐述类文本阅读〔此题一共3小题,9分〕阅读下面的文字,完成各题。
在2021年3月的人机HY中,阿尔法围棋程序〔AlphaGo〕以4比1的总比分战胜职业九段棋手李世石。
2021年末2021年初,该程序在中国棋类网站上以“HY〞〔Master〕为注册帐号与中日韩数十位围棋高手进展快棋对决,连续60局无一败绩。
面对这一切,我们不得不产生这样的忧虑:既然机器人可以战胜棋手,那么AI就有可能在其他方面代替人类,从而成为控制人类的“智能人〞或者者叫“数据生命体〞。
这就是技术的异化现象。
所谓“异化〞,是指人的物质消费与精神消费及其产品变成异己力量,反过来统治人的一种社会现象。
技术是人类创造创造的,但技术却成为人类的控制者。
为什么会出现技术异化现象呢?首先,有公利伦理与私利伦理的矛盾。
技术创造最初是源于某种公利性质的伦理,即人类不能停留在野蛮时代,人们在劳动中逐渐学会制造工具、更新工具。
但人类是分族群、分国家,分为不同的“想象一共同体〞,而不同的人群、不同的一共同体、不同的国家都是有私利的,技术创造与创新最终也就沦为私利的工具,公利伦理最终被私利伦理取代。
同时,先进的技术往往被少数人垄断,并用来控制其他弱小的人群、弱小的一共同体和弱小的国家。
这就会导致技术的异化。
其次是制度创新与技术创新之间的矛盾。
制度是调整人与人之间关系的契约,技术是处理人与自然之间关系的工具。
人类很容易解决改造自然和征服自然的工具即技术创新,但人类却很难设计一套调节人类自身关系的制度。
原因之一就在于,制度设计往往受制于设计者的私利,制度最终也会成为私利伦理下的契约关系。
但问题的关键是,制度创新与技术创新不是同一群人,也就导致了制度的私利伦理与技术的私利伦理之间的矛盾。

剪纸王孙博元旦的午后,枫城风雪交加。
北面文化中心大堂内挤满了人,温暖如春。
这里正在举办加拿大青少年剪纸大赛,参赛者有100多人,分成大、中、小学三个组别。
大学组压轴上阵,共有30多个选手。
随着主持人宣布比赛题目为“年年有余”后,大家争分夺秒地忙碌起来。
20分钟左右,牛犇第一个交卷。
作品质量和所用时间,都大大出乎评委所料。
牛犇正在读大学二年级,是滑铁卢大学计算机软件专业的高材生。
其他选手都在规定的半个小时才交卷,还有几个根本没能完工。
最终,五个评委一致决定给牛犇打100分。
评委会吴主席走上台,向大家宣布“牛犇同学以满分夺得大学组冠军,获奖金5000 加元。
这也是我们大赛举办三年来,第一个人获得满分,再次恭喜牛犇同学!”吴主席双手举起牛犇的剪纸给大家看,作品是全圆形的窗花图案,男女胖娃各抱鲤鱼跳龙门,喜气洋洋中带着积极向上的精神。
吴主席评说:“牛犇同学的作品紧扣‘年年有余’的主题,但又富有创意,融入鲤跃龙门的元素。
构图新颖,刀工流畅,疏密有致,阴阳相间……”台下一位参赛者突然举手,吴主席马上停住嘴,示意他发言。
那小伙子站起来,说道:“我叫马驰,刚才偶然发现牛犇同学的剪刀特别奇怪,估计安装了电子配件,是不是有作弊之嫌?”牛犇立刻站起来,斯文地答道“大赛要求自备剪刀和刻刀,但并没有任何具体规定。
”马驰提高嗓门:“请你不要偷换概念,我的问题是,你的剪刀有没有安装电子配件?”牛犇点点头,答道“我确实加入了人工智能辅助系统,目前主要功能是加快剪纸的速度。

第Ⅰ卷甲 必考题一、现代文阅读(9分,每小题3分)阅读下面的文字,完成1-3题。
我们的思想、学识,可以从两个源泉中得来:一、从过去学者的遗籍;二、从社会、人生与自然的直接观察.第一种思想的源泉叫做“读书”,第二种思想的源泉叫做“自主的研究",或“自主的思想”。
这两种思想源泉孰优孰劣?读书,是把前人的思想重复思想一遍.这中间有两种好处:一、脑力经济:前人由无数直接经验和研究得来的有价值的思想,我们可以不费许多脑力就得着了;二、时间经济:前人用毕生的时间得着的新发现,像开普勒定律,我们可以在一小时的时间内就领会.所以读书确有很大的价值。
但读书最大的危险,就是我们读久了,安于读书,习于以他人的思想为思想,渐渐地把“自主研究”“自主思想”的能力消灭了。
这一层,德国哲学家叔本华说得极透彻。
叔本华说:读书是拿他人的头脑,代替自己的思想。
读书读久了,我们的头脑中充满了许多外来的思想,这种外来思想纷呈堆积,东一块,西一块,好像一堆乱石,不比那由我们自己心中亲切体验发展出来的思想,可以自成一个有生气的、有机体的系统.我们常常以他人的思想为思想,以读书为唯一的思索的时间,离了书本,就茫然不能思索,得了书本,就犹鱼得水。
这种脑筋,至多是一个没有条理的藏书楼。
我们要晓得前人留下来的书籍,好比他在一片沙岸上行走时留下来的足印。
我们虽可从他这足印中看出他所行走的道路与方向,但却不能知道他在道路上所看到的景物、所发生的感想。
我们果真要了解这书籍,获得这书籍的益处,还是要自己按着这书籍所指示的道路,亲自去行走一番,直接地看这路上有些什么景物,能发生些什么感想。
叔本华并非绝对地反对读书——他自己读书之多,在欧洲学者中算是少见的—-不过他极力鼓吹自主的观察、自主的思想。
他说,书籍中的知识,犹如武士的盾甲。
一个强有力的武士,运用沉重的盾甲,可以自卫,可以攻战;一个能力薄弱的人担负了一身沉重的盾甲,反而不能行动。
所以天才能多读书而不为书籍学问所拖累;普通人多读了书,只牢记了些书本中的死知识,不能运用,不能理解,反而对社会、人生、自然失去了亲切的了解。

It was __32__ in 2011, but the country lost contact with it in March 2016 and later that year, Chinese officials confirmed that the 3.5-metre-wide __33__ would return to Earth.At the moment, scientists don't know exactly where or when the space station will enter the planet's atmosphere, but believe it will be between 30 March and 2 April. There is no need to worry, though. While scientists can't say where it will land, there is very little __34__ that the space station will hit a populated area. This is because most of it will burn up in Earth's atmosphere - a(n) __35__ of gases that protect the planet. Also, because most of Earth is covered in water, scientists think that if there is any debris, it will fall __36__ into the sea.As the __37__ landing date gets closer, scientists will be able to determine where it will fall - if necessary - steps will be taken to keep people safe and __38__. A statement by Aerospace, a US company that advises the US government about space travel, said, "In the history of spaceflight, no known person has ever been harmed by __39__ space debris(残留物)."One thing scientists are confident of, though, is that wherever it enters the atmosphere, the debris will create a spectacular fireball for anyone __40__ enough to see it.III. Reading ComprehensionsSection ADirections: For each blank in the following passage, there are four words or phrases marked A, B, C and D. Fill in each blank with the word or phrase that best fits the context.Governments are keen on higher education, seeing it as a means to boost social mobility and economic growth. Almost all sub-sidise(补贴)tuition - in America, to the tune of $200 billion a year. But they tend to overestimate the benefits and __41__ the costs of expanding university education. As more young people seek degrees, the returns both to them and to governments are __42__.Spending on universities is usually __43__ by the "graduate premium" - the increase in earnings that graduates enjoy over non-graduates. These individual gains, the thinking goes,__44__ an economic boost for society as a whole. But the graduate premium is a faulty unit of calculation. Part of the usefulness of a degree is that it gives a graduate job-seeker an advantage__45__ non-graduates. It is also a signal to employers of general qualities, such as intelligence and diligence, that someone already has in order to get into a university. Some professions require qualifications. But a degree is not always the best __46__ of the skills and knowledge needed for a job. With degrees so __47__, employers are using them as a way to screen applicants.Non-graduates are thus increasingly __48__ decent work.In any case, the premium counts only the winners and not the losers. Across the rich world, a third of university students never graduate. It is the weakest students who are drawn in as higher education __49__ and who are most likely to drop out. They pay fees and __50__ earnings to study, but see little improvement in their future incomes. When dropouts are __51__, the expected financial return to starting a degree for the weakest students shrinks to almost nothing. Many school-leavers are being __52__ about the probable value of university.Governments need to offer the young a wider range of options after school. They should start by rethinking their own __53__ practices. School-leavers should be given a wider variety of ways to gain vocation skills and to demonstrate their __54__. If school qualifications were made more difficult to get, employers would be more likely to trust them as signals of ability, and less __55__ degrees.

Each passage is followed by several questions or unfinished statements. For each of them there are four choices marked A, B, C and D. Choose the one that fits best according to the information given in the passage you have just read.(A)I wanted the pleasure of being in Africa again. Feeling that the place was so large it contained many untold tales and some hope and comedy and sweetness too, I aimed to reinsert myself in the bundy, as we used to call the bush, and to wander around. There I had lived and worked, happily, almost forty years ago, in the heart of the greenest continent.In those old undramatic days of my school teaching in the bundu, folks lived their lives on bush paths at the end of unpaved roads of red clay, in villages of grass-roofed huts. They had anew national flag, they had just gotten the vote, some had bikes, many talked about buying their first pair of shoes. They were hopeful, and so was I, a schoolteacher living near a settlement of mud-huts among trees and fields - children shouting at play; and women bent double - most with infants on their backs - hoeing(锄地)the corn beans; and the men sitting in the shade.The Swahili word safari means 'journey', it has nothing to do with animals, someone 'on safari' is just away and unobtainable and out of touch. Out of touch in Africa was where I wanted to be. The wish to disappear sends many travellers away. If you are thoroughly sick of being kept waiting at home or at work, travel is perfect: let other people wait for a change. Travel is a sort of revenge for having been put on hold, or having to leave messages on answering machines, not knowing your party's extension, being kept waiting all your working life. But also being kept waiting is the human condition.Travel in the African bush can also be a sort of revenge on mobile phones and email, on telephones and the daily paper, on the aspects of globalisation that allow anyone who chooses to get their hands on you. I desired to be unobtainable. I was going to Africa for the best of reasons - in a spirit of discover - simply to disappear, to light out, with a suggestion of I dare you to try to find me.Home had become a routine, and routine make time pass quickly. I was a sitting duck in this predictable routine: people knew when to call me, they knew when I would be at my desk. I was in such regular touch it was like having a job, a mode of life I hated .. I was sick of being called up and asked for favors, hit up for money. You stick around too long and people begin to impose their own deadlines on you.56. What did the writer expect from his journey?A. To have a variety of enjoyable experiences.B. To see how Africa had changed.C. To see impressive scenery.D. To meet some old friend.57. Forty years ago, how did the writer feel about the future of the country where he was living?A. Little was likely to change.B. Things were likely to improve.C. Women would do most of the work.D. People's expectations were too limited.58. In paragraph 3, what reason does the writer give for wanting to travel to Africa?A. He wanted a change of activity.B. He wanted people to be unable to contact him.C. His health was suffering from staying at home.D. He had been waiting to return to Africa for long.59. The writer says 'I was a sitting duck' in paragraph 5 to show that _________.A. he was boringB. he was easy to findC. he had a fixed lifestyleD. he was always lending money(B)The house style that dominated American housing during the 1880s and 1890s was known as Queen Anne, a curious name for an American style. The name was, in fact, a historical accident, originating with fashionable architects in Victorian England who coined it with apparently no reason other than its pleasing sound. The Queen Anne style was loosely based on structures built long before 1702, the beginning year of Queen Anne's reign(统治期).A distinctive characteristic found in most Queen Anne houses is the unusual roof shape (illustrated in the picture on the right) - a steeply pitched, hipped central portion with protruding lower front and side extensions that end in gables. It is often possible to spot these distinctive roof forms from several blocks away. Another feature of this style is the detailing, shown in the wood board siding cut into fanciful decorative patterns of scallops, curves, diamonds, or triangles. Queen Anne houses are almost always asymmetrical(不对称的). If you draw an imaginary line down the middle of one, you will see how different the right and left sides are, all the way from ground level to roof peak. A final characteristic is the inviting wraparound porch(门廊)that includes the front door area and then extends around to either the right or left side of the house.Queen Anne houses faded from fashion early in the twentieth century as the public's taste shifted toward the more modern Prairie and Craftsman style houses. Today, however, Queen Annehouses are favorite symbols of the past, painstakingly and lovingly restored by old-house buffs and reproduced by builders who give faithful attention to the distinctive shapes and detailing that were first popularized more than one hundred years ago.60. Why does the author use the word "curious" (in paragraph 1) in describing the name of an American style?A. The style was invented before Queen Anne's reign.B. The style was more popular in Victorian England.C. The name was accidentally misspelled.D. The name did not originate in America.61. Which of the following can be inferred from paragraph 2 about the Queen Anne style?A. It was not very popular.B. It had to be build in the city.C. It combined several other styles.D. It was elaborate and fancily decorated.62. According to passage, why did Queen Anne houses go out of style?A. People started moving to the suburbs.B. People came to see them as a symbol of the past.C. People were more interested in newer house styles.D. People could no longer afford to build such large houses.(C)What will the development of quantum computers(量子计算机)mean for our civilisations? Oh sure, better cryptography(密码方式), "more powerful" processing, but bottom line, we just don't know ... yet.This phenomenon isn't unique to quantum computing, of course. It's something we see time and gain with all new world-changing technology. In some ways, it's how we can define a technology as world-changing: everyone agrees it's going to be hugely important, but nobody can predict exactly what impact it will have.The internet remains the classic example. Although invented in the 1960s, even by the late 1990s, the internet was still being dismissed as something that is fashionable but unlikely to last. Most commentators thought it nothing more than a curiosity.There's a famous 1999 interview between David Bowie and BBC journalist Jeremy Paxman. In it, Bowie predicts that the internet will change the nature of music, and remove the "barriers between creator and audience". The longer he spoke, the more Paxman said in anger that Bowie could possibly believe this about the internet.To be fair to Paxman, in 1999, internet at home meant accessing it over a modern. Concepts like WeChat and Netflix and more simply could not work over such limited bandwidth. But there were still some people who assumed that bandwidth would increase and that streaming music and video would be possible soon enough. They were laughed at.Oddly enough, as the dot-com boom intensified, many turned from doubters to hopeless optimists, and lost serious money building websites to deliver content that simply couldn't "fit" down the inter-tubes of the day.Then in the second decade of the 21st century: critical mass. Bandwidth increased massively. Forget showing a nice little video in your browser, today Nexflix can serve you a TV show in 4K, as long as you have 25Mbps connection.Quantum computing isn't a consumer technology, of course. It's a much bigger deal than that. Quantum computing is more like the invention of the transistor(电子晶体). Sure, most people have heard of it, but few understand it. Actually, we don't even really understand it. But we're reasonably comfortable that when a lab has that many scanning electron microscopes, it must be doing something important, right?Quantum computing is still at the stage of "hit it with a hammer until it works". Sure the hammer is microscopic, and also a laser or magnetic field of some kind, but the point is we're going through the process of turning the idea into reality.Sooner than you think, though, qubit-based computers are going to get applied to stuff. What stuff? Like always, it will be super secret stuff first. Then it will reach the rest of us.This is how the world begins. Not with a bang, but with a lot of extremely hard work behind the scenes.63. What attitude did most people take towards the internet in the 1990s?A. Optimistic.B. Unconcerned.C. Doubtful.D. Defensive.64. The example of the internet is intended to illustrate that ________.A. it is hard to define what is world-changing technologyB. the internet was universally acknowledged as importantC. the influence of new technology is usually unpredictableD. the internet inspired many debates in the following years65. By "hit it with a hammer until it works", the writer means that quantum computing ________.A. has been questionedB. has been fully understoodC. hasn't been heard of beforeD. hasn't been applied to practice66. What can be concluded about new technology from the passage?A. Its development is a gradual process.B. Most is the brainchild of a scientist.C. Not all is accessible to the public.D. Its future is often a top secret.Section CDirections: Read the passage carefully. Fill in each blank with a proper sentence given in the box.The internet already enables patients to seek online consultations when and where it suits them. Yet change demands a shift in emphasis, from providers to patients and from doctors to data. ________67________ Technologies such as the smartphone allow people to monitor their own health. The possibilities multiply when you add the crucial missing ingredients - access to your own treatment and also to provide data to help train medical programmes.________68________ One is better diagnosis. Someone worried about their heart can now buy a watch strap containing a medical grade monitor that will detect arrhythmias(心律失常). Apps are trying to see if they can diagnose everything from skin cancer to Parkinson's disease. Research is under way to see whether sweat can be analysed for molecular biomarkers without the need for an invasive blood test.A second benefit lies in the management of complex diseases. Diabetes(糖尿病)apps can change the way patients cope, by monitoring blood-glucose levels and food intake, potentially reducing long-run harm such as blindness. Akili Interactive, a startup, plans to seek regulatory approval for a video game designed to stimulate an area of the brain implicated in attention-deficit hyperactivity disorder.________69________ Although health records are increasingly electronic, many still contain data that machines cannot read. This can lead to delays in treatment, or worse. Many of the 250,000 death in America owed to medical error each year can be traced to poorly arranged care. ________70________ On January 24th Apple laid out its plans to ask organisations to let patients use their smartphones to download their own medical records.IV.

Use your own words as far as possible.Change Is Needed In Youth SportsEverywhere you look, you see kids bouncing a basketball or waving a tennis bat. And these kids are getting younger and younger. Children can even compete on basketball, baseball, and volleyball teams starting at age nine. The youth soccer organization has teams for children asyoung as five. And swimming and gymnastics classes begin at age four, to prepare children for competition.It's true that a few of these kids will develop into highly skilled athletes and may even become members of our national Olympic teams. But what about the others - the average kids? This emphasis on competition in sports is having serious negative effects.Children who get involved in competitive sports at a young age often grow tired of their sport. Many parents pressure their kids to choose one sport and devote all their time to it. A survey found that 79 percent of parents of young athletes wanted their children to concentrate on one sport. But 66 percent of the young athletes wanted to play more than one sport - for fun.Another problem is the pressure imposed by over-competitive parents and coaches. Children are not naturally competitive. In fact, a recent study by Paulo David found that most children don't even understand the idea of competition until they are seven years old. Very young kids don't know why their parents are pushing them so hard.The third, the biggest, problem for young athletes is the lack of time to do their homework, have fun, be with friends - in short, time to be kids. When they are forced to spend every afternoon at sports practice, they often start to hate their chosen sport. Researchers found that 70 percent of kids who take part in competitive sports before the age of twelve quit before they turn eighteen. Many of them completely lose interest in sports. Excessive competition takes away all the enjoyment.V. TranslationDirections: Translate the following sentences into English, using the words given in the brackets.72. 对进口设备的禁令还未取消。

Tuesday night, OpenAI published several of Musk’s emails from the early days of the company that appear to show Musk acknowledging OpenAI needed to make a ton of money to fund the incredible computing resources needed to power 2 AI ambitions.In the emails, parts of 3 have been redacted (修订), Musk argues that the company stood virtually no chance of building a successful generative AI platform by raising cash alone, and the company needed to find alternate sources of revenue to survive.In a November 22, 2015, email to CEO Sam Altman, Musk, an OpenAI co-founder, said the company needed to raise much more than $100 million to “avoid sounding hopeless.” Musk suggested a $1 billion funding commitment and promised that he would cover 4 did not get raised.OpenAI in a blog post Tuesday night said Musk never followed through on his promise, 5 (commit) $45 million in funding for OpenAI, 6 other donors raised $90 million. Lawyers for Musk declined to comment on OpenAI’s claims.Musk, in a February 1, 2018, email, told company executives that the only path forward for OpenAI was for Tesla, his electric car company, to buy it. The company refused, and Musk left OpenAI later that year.In December 2018, Musk emailed Altman and other executives that OpenAI would not be relevant “ 7 a dramatic change in execution and resources.”“This needs billions per year immediately or forget it,” Musk emailed. “I really hope I’m wrong.”OpenAI executives agreed. In 2019, they formed OpenAI LP, a for-profit entity that exists within the larger company’s structure. That for-profit company took OpenAI from effectively worthless to a valuation of $90 billion in just a few years — and Altman 8 (credit) as the mastermind of that plan and the key to the company’s success.Microsoft has since committed $13 billion in a close partnership with OpenAI.Musk’s complaint, 9 (file) last week in California state court, said that company and its partnership with Microsoft violated OpenAI’s founding charter, representing a breach of contract. Musk is asking for a jury trial and for the company 10 (pay) back the profit they received from the business.二、选词填空Directions: Complete the following passage by using the words in the box.

Here’s what happenedOne German man has redefined “man on a mission.” A 62-year-old from Magdeburg deliberately got 217 Covid-19 vaccine shots in the 11 of 29 months, according to a new study, going against national vaccine recommendations. That’s an average of one jab every four days. In the process, he became a(n) 12 experiment for what happens to the immune system when it is vaccinated against the same pathogen (病原体) repeatedly. A correspondence published Monday in the journal Lancet Infectious Diseases 13 his case and concluded that while his “hypervaccination” did not result in any adverse health effects, it also did not significantly improve or worsen his immune response.The man, who is not named in the correspondence in compliance with German privacy rules, reported receiving 217 Covid shots between June 2021 and November 2023. Of those, 134 were 14 by a prosecutor and through vaccination center documentation; the remaining 83 were self-reported, according to the study.“This is a really unusual case of someone receiving that many Covid vaccines, 15 not following any type of guidelines,” said Dr. Emily Happy Miller, an assistant professor of medicine and of microbiology and immunology at Albert Einstein College of Medicine who did not participate in the research.The man did not report any vaccine-related side effects and has not had a Covid infection to date, as 16 by repeated antigen (抗原) and PCR testing between May 2022 and November 2023. The researchers 17 that it’s not clear that his Covid status is directly because of his hypervaccination regimen.“Perhaps he didn’t get Covid because he was 18 in the first three doses of the vaccine,” Miller said. “We also don’t know anything about his behaviors.” Dr. Kilian Schober, senior author of the new study and a researcher at the Friedrich-Alexander University Erlangen-Nürnberg, said it is important to remember that this is an individual case study, and the results are not 19 .The researchers also say they do not endorse hypervaccination as a strategy to enhance immunity. “The benefit is not much bigger if you get vaccinated three times or 200 times,” Schober said.The public prosecutor in Magdeburg opened an investigation into the man for the unauthorized issuing of vaccination cards and forgery of documents but did not end up filing criminal 20 , according to the study.三、完形填空A Neurologist’s Tips to Protect Your MemoryAs we age, our memory declines. This is a fixed 21 for many of us; however, according to neuroscientist Dr. Richard Restak, a neurologist and clinical professor, decline is not 22 .Ultimately, “we are what we can remember,” he said. Here are some of Dr. Restak’s tips for developing and 23 a healthy memory.Pay more attention.Some memory lapses are actually attention problems, not memory problems. 24 , if you’ve forgotten the name of someone you met at a cocktail party, it could be because you weretalking with several people at the time.One way to pay attention when you learn new information is to 25 the word. Having a picture associated with the word, Restak said, can improve 26 . Find regular everyday memory challenges.There are many memory exercises that you can 27 into everyday life. Dr. Restak suggested composing a grocery list and memorizing it. When you get to the store, don’t 28 pull out your list (or your phone) — instead, pick up everything according to your memory.Once in a while, get in the car without turning on your GPS, and try to 29 through the streets from memory. A small 2020 study suggested that people who used GPS more frequently over time showed a steeper cognitive 30 in spatial memory three years later.Play games.Dr. Restak’s “favorite working memory game” is 20 Questions — in which a group thinks of a person, place or object, and the other person, the questioner, asks 20 questions with a yes-or-no answer. Because to succeed, he said, the questioner must hold all of the 31 answers in memory in order to guess the correct answer.The point is to 32 your working memory, “maintaining information and moving it around in your mind,” Restak wrote.Read more novels.One early indicator of memory issues, according to Dr. Restak, is 33 fiction. “People, when they begin to have memory difficulties, tend to switch to reading nonfiction,” he said. Fiction requires active engagement with the text, starting at the beginning and working through to the end. 34 technology.Storing everything on your phone means that “you don’t know it,” Dr. Restak said, which can 35 our own mental abilities. The second way our relationship with technology is harmful to memory is because it often takes our focus away from the task at hand. 21.A.accomplishment B.assumption C.regulationD.observation22.A.inevitable B.dispensable C.reverse D.doubtful 23.A.striking B.enduring C.arousing D.maintaining 24.A.Nevertheless B.Moreover C.For instance D.Instead 25.A.demonstrate B.trace C.discover D.visualize26.A.recall B.sight C.target D.instinct 27.A.enclose B.integrate C.evolve D.impose 28.A.steadily B.actively C.gradually D.automatically 29.A.adjust B.rush C.gesture D.navigate 30.A.performance B.decline C.awareness D.increase 31.A.modest B.original C.previous D.personal 32.A.engage B.drain C.insert D.fulfill 33.A.devoting to B.concentrating on C.giving in to D.giving up on 34.A.Beware of B.Stick to C.Long for D.Differ from 35.A.counter B.stock C.erode D.strengthen四、阅读理解The last few months had brought to my attention an important incompatibility between us — one that I’d never noticed before. Despite being a pair of lifelong travelers, Felipe and I seldom travel in a similar way. The reality about Felipe is that he’s both the best traveler I’ve ever met and by far the worst. He hates strange bathrooms and dirty restaurants and uncomfortable trains and foreign beds. Given a choice, he will always select a lifestyle of routine, familiarity, and reassuringly boring everyday practices. All of which might make you assume that the man is not fit to be a traveler at all. But you would be wrong to assume that, for here is Felipe’s traveling gift, his superpower, the secret weapon that makes him peerless. He can create a familiar habitat of boring everyday practices for himself anyplace, if you just let him stay in one spot. He can assimilate absolutely anywhere on the planet in about three days, and then he’s capable of staying put in that place for the next decade or so without complaint. This is why Felipe has been able to live all over the world. Not merely travel, but live. Over the year he has folded himself into societies from South America to Europe, from the Middle East to the South Pacific. He arrives somewhere totally new, decides he likes the place, moves right in, learns the language, and instantly becomes a local.While Felipe can find a corner anywhere in the world and settle down for good, I can’t. I am infinitely curious and almost infinitely patient with minor disasters, which makes me a farbetter day-to-day traveler than he will ever be. So I can go anywhere on the planet—that’s not a problem. The problem is I just can’t live anywhere on the planet. I’d realized this only a few weeks earlier, back in northern Laos, when Felipe had woken up one lovely morning in Luang Prabang and said, “Darling, let’s stay here.”“Sure,” I’d said. “We can stay here for a few more days if you want.”“No, I mean let’s move here. Let’s forget about me immigrating to America. It’s too much trouble. This is a wonderful town. I like the feeling of it. It reminds me of Brazil thirty years ago. It wouldn’t take much money or effort for us to run a little hotel or shop here, rent an apartment, settle in ….” He was serious. He would just do that. But I can’t.36.The word “incompatibility” (paragraph 1) is closest in meaning to “_____”.A.harmony B.negotiation C.difference D.tension 37.According to the writer, what is Felipe’s traveling gift?A.He can speak dozens of languages.B.He can make himself at home anywhere.C.He can decide at first sight if he likes the place.D.He can find interesting activities in boring places.38.According to the writer, why is she a better traveler than Felipe?A.She is much more restless than he is.B.She can travel for a longer time than he can.C.She is more curious about local life than he is.D.She can live better in poor places than he can.39.By “I can’t” (in the last paragraph), the writer means that she can’t _____.A.remember the trip to Brazil B.move to Luang PrabangC.immigrate to America as planned D.run a little hotel or shop wellOutdoor RecreationGet outdoors with us this summer and experience the excitement and peace within our unique programs.

Music, drama, dance, visual arts, poetry and literature are among the most precious human achievements. To live in a country in which these are more widely shared and enjoyed would be proof that we are making progress. The point is not to entertain or educate people, or bring communities together. Nor is it all about boosting jobs and investment. Imagination has intrinsic (内在的) value, and research carried out by ACE in the course of preparing its 10-year strategy showed that people from all walks of life value and get pleasure from cultural activities.Positioning itself as a development agency, ACE will now hope to win government backing for a change of direction that orients it away from the biggest and most prestigious national institutions and towards the towns, villages and grassroots organizations that should be similarly deserving of attention. There, it envisions a role for itself “building the identity and prosperity of places,” bringing professional artists together with voluntary groups, particular in areas that have previously not been well represented on the cultural map.ACE’s chair, Sir Nicholas Serota, quotes the first world war centenary (百年纪念) project devised by the artist, Jeremy Deller, and theatre director, Rufus Norris, as the model of what he wants his organization to be about. By dressing up volunteers as soldiers, and orchestrating their encounters with members of the public in settings across England, the artists succeeded in “dissolving the barriers between artists and audiences.”The emphasis on participation- on culture as something that more people should actually do- is newer. This is the difference between being in a play or a band and buying tickets to watch them, and for ACE to play a more active role in promoting the former would be beneficial. Thisbegins in childhood, and ACE clearly hopes that the government will think again about policies that have seen music, drama and other arts subjects systematically downgraded in favour of science, technology and maths.To what extent the vision is realized will depend in part on whether ACE’s ambitions catch the government’s interest sufficiently to influence the upcoming spending review, and provide a counterweight to the scorn (轻视) that is regularly poured on the humanities. Around £400m has been cut from local government arts budgets since 2010, and ACE cannot plug this gap. The closure of youth clubs and live music venues, and growing financial pressures linked to the property market, are among other reasons for this worrisome narrowing of opportunities. So far Boris Johnson has offered few signs that he has in mind a starring role for the arts in post-Brexit Britain, although 2022’s Festival of Brexit is one such event. ACE’s plan should boost the profile of all those, in government and outside, who are arguing for more.43.The purpose of making arts available to more people is to __________.A.enlighten people from all walks of lifeB.consolidate various communitiesC.create job opportunities for artistsD.maximize the natural value of art44.According to the passage, ACE is most likely to promote the arts of ___________.A.national institutionsB.commercial centersC.local governmentsD.towns and villages45.Which of the following statements would Sir Nicholas Serota most probably agree with?A.Audiences with little education can also gain pleasure from cultural activities.B.Artists and audiences can create and enjoy the arts together without barriers.C.The soldiers and volunteers should vividly show scenes about the First World War.D.Science, technology and maths are more important than humanities and arts nowadays. 46.What can be inferred from the last paragraph?A.For the arts to get revitalized more extensive efforts are needed.B.The current British government has done enough to promote arts.C.ACE should narrow the financial gap left by the local government.D.Many performing venues have closed due to the rising property market.Directions: Read the following passage. Fill in each blank with a proper sentence given in the box. Each sentence can be used only once. Note that there are two more sentences than you need.What Your “Age” Says About YouImagine, for a moment, that you had no birth certificate and your age was simply based on the way you feel inside. How old would you say you are?Like your height or shoe size, the number of years that have passed since you first entered the world is an unchangeable fact. 47Scientists are increasingly interested in this quality. They are finding that our “subjective age” may be essential for understanding the reasons why some people appear to be energetic as they grow old — while others fade.48 It is now well accepted that people tend to mature as they get older, becoming less extroverted ( 外向的) and less open to new experiences. These personality changes are often considered more obvious in the people with older subjective ages.However, those who feel younger than they really are also become more reliable and less neurotic ( 神经质的) as they gain the wisdom that comes with greater life experience. But it doesn’t come at the cost of the energy and vigor of youth. It’s not true that having a lower subjective age leaves us frozen in a state of permanent immaturity.Feeling younger than your years also seems to come with a lower risk of depression and greater mental wellbeing as we age. 49 Most people felt about eight years younger than their actual chronological age (实际年龄). But some felt they had aged — and the consequences were serious. Feeling between 8 and 13 years older than your actual age resulted in an 18-25% greater risk of death over the study periods, and greater disease burden — even when you control for other demographic ( 人口学的) factors such as education, race or marital status.50 However old you really are, it’s worth questioning whether any of those limitations are coming from the within.A.It also means better physical health.B.One of the most interesting aspects of the research has explored how subjective age interacts with our personality.C.Some studies have explored the potential physical consequences of this difference. D.These findings can give us all a view of the way our own brains and bodies endure the passing of time.E.But everyday experience suggests that people often don’t experience ageing the same way. F.Many researchers are now trying to study how this knowledge might help us live longer.五、书面表达51.Directions: Read the following passage. Summarize the main idea and the main point(s) of the passage in no more than 60 words. Use your own words as far as possible.What We Should Know about HoneyThe process that produces honey may have helped form humans too. Scientists believe that wild hives full of honey provided the calories that early humans such as Homo erectus (直立人), walking in Africa , needed to develop their brains into those of modern humans. That puts honey in a class with fire, tool use, and hunting as a key ingredient in the evolution of human beings.With time, those evolved brains learned to domesticate bees to produce honey in a farmed setting. Today’s beekeepers support large-scale industrial farms, which would be unable to grow their crops without hiring traveling groups of bees to come pollinate (授粉) their vast, single-species fields. The bees will endlessly fill the towers of combs put onto their hives by the beekeeper, who then collects the extra honey for human consumption while still leaving the bees all they need to eat.Today, the average American consumes nearly a pound and a half of honey every year, in tea, on toast, and beyond. Honey is a timeless treasure. Literally—it never goes bad. Samples nearly 3,000 years old found in the Egyptian pyramids are as eatable as the day they were entombed. Its anti-microbial nature also makes honey an excellent cure for wounds, keeping infection out while holding in the moisture that skin needs to heal.However, bees’ good health is not guaranteed. U.S. beekeepers lose about 40 percent of their hives annually to colony collapse disorder. The problem lies in the growth of industrialagriculture and pesticide use, as well as changes in weather patterns, all of which reduce the number of flowers bees have to visit. If bees continue to die, apples and peaches (along with any crop that relies on their pollination) will become scarcer and pricier. As will honey._______________________________________________________________________________ _______________________________________________________________________________ _______________________________________________________________________________ _______________________________________________________________________________ _______________________________________________________________________________六、翻译52.在成人仪式上,读了父母的肺腑之言后他情不自禁潸然泪下。
