What he was most interested in, he began, was stillness and quiet.A few months later, I read an interview with the well-known cutting-edge designer Philippe Starck.What allowed him to remain so consistently ahead of the curve? “I never read any magazines or watch TV,” he said, perhaps with a little exaggeration. “Nor do I go to cocktail parties, dinners or anything like that.” He lived outside conventional ideas, he implied, because “I live alone mostly, in the middle of nowhere.”Around the same time, I noticed that those who part with $2,285 a night to stay in a cliff-top room at the Post Ranch Inn in Big Sur, California, pay partly for the privilege of not having a TV in their rooms; the future of travel, I’m reliably told, lies in “black-hole resorts,” whi ch charge high prices precisely because you can’t get online in their rooms.Has it really come to this?The more ways we have to connect, the more of us seem desperate to unplug. Internet rescue camps in South Korea and China try to save kids addicted to the screen.Writer friends of mine pay good money to get the Freedom software that enables them to disable the very Internet connections that seemed so emancipating not long ago. Even Intel experimented in 2007 with conferring four uninterrupted hours of quiet time (no phone or e-mail) every Tuesday morning on 300 engineers and managers. Workers were not allowed to use the phone or send e-mail, but simply had the chance to clear their heads and to hear themselves think.The average American spends at least eight and a half hours a day in front of a screen, Nicholas Carr notes in his book The Shallows. The average American teenager sends or receives 75 text messages a day, though one girl managed to handle an average of 10,000 every 24 hours for a month.Since luxury is a function of scarcity, the children of tomorrow will long for nothing more than intervals of freedom from all the blinking machines, streaming videos and scrolling headlines that leave them feeling empty and too full all at once.The urgency of slowing down—to find the time and space to think—is nothing new, of course, and wiser souls have always reminded us that the more attention we pay to the moment, the less time and energy we have to place it in some larger context. “Distraction is the only thing that consoles us for our miseries,” the French philosopher Blaise Pascal wrote in the 17th century, “and yet it is itself the greatest of our miseries.” He also famously remarked that all of man’s problems come from his inability to sit quietly in a room alone.When telegraphs and trains brought in the idea that convenience was more important than content, Henry David Thoreau reminded us that “the man whose horse trots (奔跑), a mile in a minute does not carry the most important messages.”Marshall McLuhan, who came closer than most to seeing what was coming, warned, “When things come at you very fast, naturally you lose touch with yourself.”We have more and more ways to communicate, but less and less to say. Partly because we are so busy communicating. And we are rushing to meet so many deadlines that we hardly register that what we need most are lifelines.So what to do? More and more people I know seem to be turning to yoga, or meditation (沉思), or tai chi (太极) ；these aren’t New Age fads (时尚的事物) so much as ways to connect with what could be called the wisdom of old age. Two friends of mine observe an “Internet Sabbath (安息日)” every week, turning off their online connections from Friday night t o Monday morning. Other friends take walks and “forget” their cellphones at home.A series of tests in recent years has shown, Mr. Carr points out, that after spending time in quiet rural settings, subjects “exhibit greater attentiveness, stronger memory a nd generally improved cognition. Their brains become both calmer and sharper.” More than that, empathy (同感，共鸣) ，as well as deep thought, depends (as neuroscientists like Antonio Damasio have found) on neural processes that are “inherently slow.”I turn to eccentric measures to try to keep my mind sober and ensure that I have time to do nothing at all (which is the only time when I can see what I should be doing the rest of the time).I have yet to use a cellphone and I have never Tweeted or entered Facebook. I try not to go online till my day’s writing is finished, and I moved from Manhattan to rural Japan in part so I could more easily survive for long stretches entirely on foot.None of this is a matter of asceticism (苦行主义) ；it is just pure selfishness. Nothing makes me feel better than being in one place, absorbed in a book, a conversation, or music. It is actually something deeper than mere happiness: it is joy, which the monk (僧侣) David Steindl-Rast describes as “that kind of happiness that doesn’t depend on what happens.”It is vital, of course, to stay in touch with the world. But it is only by having some distance from the world that you can see it whole, and understand what you should be doing with it.For more than 20 years, therefore, I have been going several times a year—often for no longer than three days—to a Benedictine hermitage (修道院) ，40 minutes down the road, as it happens, from the Post Ranch Inn. I don’t attend services when I am there, and I have never meditated, there or anywhere; I just take walks and read and lose myself in the stillness, recalling that it is only by stepping briefly away from my wife and bosses and friends that I will have anything useful to bring to them. The last time I was in the hermitage, three months ago, I happened to meet with a youngish-looking man with a 3-year-old boy around his shoulders.“You’re Pico, aren’t you?” the man said, and introduced himself as Larry; we had met, I gathered, 19 years before, when he had been living in the hermitage as an assistant to one of the monks.“What are you doing now?” I asked.We smiled. No words were necessary.“I try to bring my kids here as often as I can,” he went on. The child of tomorrow, I realized, may actually be ahead of us, in terms of sensing not what is new, but what is essential.1.

What does the author say about yoga, meditation and tai chi?A) They help people understand ancient wisdom.B) They contribute to physical and mental health.C) They are ways to communicate with nature.D) They keep people from various distractions.6.

Read the passage carefully. Then answer the questions or complete the statements in the fewest possible words. Please write your answers on Answer Sheet 2.Questions 47 to 54 are based on the following passage.A key process in interpersonal interaction is that of social comparison, in that we evaluate ourselves in terms of how we compare to others. In particular, we engage in two types of comparison. First, we decide whether we are superior or inferior to others on certain dimensions, such as attractiveness, intelligence, popularity, etc. Here, the important aspect is to compare with an appropriate reference group. For example, modest joggers should not compare their performance with Olympic standard marathon (马拉松) runners. Second, we judge the extent to which we are the same as or different from others. At certain stages of life, especially adolescence, the pressure to be seen as similar to peers is immense. Thus, wearing the right brand of clothes or shoes may be of the utmost importance. We also need to know whether our thoughts, beliefs and ideas are in line with those of other people. This is part of the process of self-validation whereby we employ self-disclosures to seek support for our self-concept.People who do not have access to a good listener may not only be denied the opportunity to heighten their self-awareness, but they are also denied valuable feedback as to the validity and acceptability of their inner thoughts and feelings. By discussing these with others, we receive feedback as to whether these are experiences which others have as well, or whether they are less common. Furthermore, by gauging the reactions to our self-disclosures we learn what types are acceptable or unacceptable with particular people andin specific situations. On occasions it is the fear that certain disclosures may be unacceptable to family or friends that motivates an individual to seek professional help. Counsellors will be familiar with client statements such as: “I just couldn’t talk about this to my husband.”, “I really can’t let my mother know my true feelings.” Another aspect of social comparison in the counselling context relates to a technique known as normalizing. This is the process whereby helpers provide reassurance to clients that what they are experiencing is not abnormal or atypical (非典型的), but is a normal reaction shared by others when facing such circumstances. Patient disclosure, facilitated by the therapist, seems also to facilitate the process of normalizing.47. To evaluate ourselves, the author thinks it important for us to compare ourselves with _______.48. During adolescence, people generally feel an immense pressure to appear _______.49. It is often difficult for people to heighten their self-awareness without _______.50. What can people do if they find what they think or say unacceptable to family or friends?51. Counsellors often assure their clients that what they experience themselves is only _______.Section BDirections: There are 2 passages in this section. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A）, B）, C） and D）. You should decide on the best choice and mark the corresponding letter on Answer Sheet 2 with a single line through the centre. Passage OneQuestions 52 to 56 are based on the following passage.Amid all the job losses, there’s one category of worker that the economic disruption has been good for: nonhumans.From self-service checkout lines at the supermarket to industrial robots armed with saws and taught to carve up animal bodies in slaughter-houses, these ever-more-intelligent machines are now not just assisting workers but actually kicking them out of their jobs.Automation isn’t just affecting factory workers, either. Some law firms now use artificial intelligence software to scan and read mountains of legal documents, work that previously was performed by highly-paid human lawyers.“Robots continue to have an impact on blue-collar jobs, and white-collar jobs are under attack by microprocessors,” says economics professo r Edward Leamer. The recession permanently wiped out 2.5 million jobs. U.S. gross domestic product has climbed back to pre-recession levels, meaning we’re producing as much as before, only with 6% fewer workers. To be sure, robotics are not the only job killers out there, with outsourcing (外包) stealing far more jobs than automation.Jeff Burnstein, president of the Robotics Industry Association, argues that robots actually save U.S. jobs. His logic: companies that embrace automation might use fewer work ers, but that’s still better than firing everyone and moving the work overseas.It’s not that robots are cheaper than humans, though often they are. It’s that they’re better. “In some cases the quality requirements are so exacting that even if you wanted t o have a human do the job, you couldn’t,” Burnstein says.Same goes for surgeons, who’re using robotic systems to perform an ever-growing list of operations—not because the machines save money but because, thanks to the greater precision of robots, the patients recover in less time and have fewer complications, says Dr. Myriam Cruet.Surgeons may survive the robot invasion, but others at the hospital might not be so lucky, as iRobot, maker of the Roomba, a robot vacuum cleaner, has been showing off Ava, which could be used as a messenger in a hospital. And once you’re home, recovering, Ava could let you talk to your doctor, so there’s no need to send someone to your house. That “mobile telepresence” could be useful at the office. If you’re away on a trip, you can still attend a meeting. Just connect via videoconferencing software, so your face appears on Ava’s screen.Is any job safe? I was hoping to say “journalist,” but researchers are already developing software that can gather facts and write a news story. Which means that a few years from now, a robot could be writing this column. And who will read it? Well, there might be a lot of us hanging around with lots of free time on our hands.注意：此部分试题请在答题卡2上作答。

Green jobs are those that contribute to environmental protection and sustainable development. These jobs can be found in various sectors, suchas renewable energy, energy - efficient building, and waste management. The growth of green jobs is driven by several factors. Firstly, the increasing awareness of environmental issues has led to a greater demand for environmentally - friendly products and services. Secondly, government policies and incentives play an important role. Many governments around the world are providing subsidies and tax breaks to encourage the developmentof green industries. Thirdly, technological advancements have made it possible to develop more efficient and cost - effective green technologies.However, the development of green jobs also faces some challenges. One of the challenges is the lack of trained personnel. Since green jobs often require specialized knowledge and skills, there is a shortage of workers who are qualified to fill these positions. Another challenge is the high cost of some green technologies, which may limit their widespread adoption.32. What are green jobs according to the passage?A) Jobs that are related to plants and forests.B) Jobs that are only available in the environmental protection department.C) Jobs that contribute to environmental protection and sustainable development.D) Jobs that require workers to wear green uniforms.33. What drives the growth of green jobs?A) Only the increasing awareness of environmental issues.B) The increasing awareness of environmental issues, governmentpolicies and incentives, and technological advancements.C) Only government policies and incentives.D) Only technological advancements.34. What is one of the challenges faced by the development of green jobs?A) There are too many trained personnel.B) The lack of trained personnel.C) The low cost of green technologies.D) The over - adoption of green technologies.35. Which of the following sectors may not have green jobs?A) Renewable energy.B) Energy - efficient building.C) Traditional coal mining.D) Waste management.36. What can be inferred from the passage about green jobs?A) They are not very important for the future.B) They will develop without any difficulties.C) They have both opportunities and challenges.D) They are only popular in developed countries.Passage 2.Questions 37 - 41 are based on the following passage.In the digital age, e - books have become increasingly popular. They offer several advantages over traditional printed books. For one thing, e - books are more convenient. You can carry a whole library of e - books on a single device, such as a tablet or an e - reader. This means you can have access to a wide range of reading materials wherever you are. For another, e - books are often cheaper than their printed counterparts. Publishers can save on the cost of printing and distribution, and these savings can be passed on to the consumers.However, e - books also have some disadvantages. One problem is that reading e - books for a long time may cause eye strain. The backlit screens of e - readers and tablets can be tiring on the eyes, especially in low - light conditions. Another issue is that some people simply prefer the feelof a physical book in their hands. The texture of the paper, the smell of the ink, and the act of turning the pages all contribute to the reading experience for these people.37. What are the advantages of e - books?A) They are more expensive.B) They are less convenient.C) They are more convenient and often cheaper.D) They are only available on one device.38. Why are e - books often cheaper?A) Because publishers don't want to make money.B) Because publishers can save on the cost of printing and distribution.C) Because e - books are of lower quality.D) Because the government subsidizes e - books.39. What is one of the disadvantages of e - books?A) They can't be read on any device.B) They may cause eye strain.C) They are always more expensive than printed books.D) They have no page - turning function.40. Who may not like e - books according to the passage?A) People who like to read a lot.B) People who care about the cost.C) People who prefer the feel of a physical book.D) People who are always on the go.41. What can be concluded from the passage about e - books?A) They will completely replace printed books in the future.B) They are not as good as printed books in any aspect.C) They have both pros and cons.D) They are only suitable for young people.Section C.Directions: There are 2 passages in this section. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A), B), C) and D). You should decide on the best choice and mark the corresponding letter on Answer Sheet 2.Passage 1.Questions 42 - 46 are based on the following passage.The sharing economy has emerged as a new economic model in recent years. It is based on the idea of sharing under - utilized resources, such as cars, houses, and tools. Platforms like Uber and Airbnb have become very popular, allowing people to earn extra income by sharing their assets.One of the main benefits of the sharing economy is that it can make more efficient use of resources. For example, instead of having a large number of cars sitting idle in parking lots, they can be used by others through car - sharing services. This can also reduce the need for new production, which is beneficial for the environment. Another advantage is that it can provide more affordable options for consumers. For instance, staying in an Airbnb accommodation is often cheaper than a hotel.However, the sharing economy also faces some challenges. One issue is the lack of regulation. Since it is a relatively new model, there are not enough laws and regulations to ensure fair competition and protect consumers. For example, some Uber drivers may not have proper insurance, which can pose a risk to passengers. Another problem is the quality control. It can be difficult to ensure the quality of shared resources, such as the cleanliness and safety of an Airbnb rental.42. What is the sharing economy based on?A) Buying new resources.B) Sharing under - utilized resources.C) Producing more resources.D) Wasting resources.43. What are the benefits of the sharing economy?A) It can make resources less efficient.B) It can only provide expensive options for consumers.C) It can make more efficient use of resources and provide more affordable options for consumers.D) It has no benefits at all.44. What are the challenges faced by the sharing economy?A) The over - regulation.B) The lack of regulation and quality control.C) The too - strict quality control.D) The high cost of production.45. Why is the lack of regulation a problem in the sharing economy?A) Because it ensures fair competition.B) Because it protects consumers.C) Because there are not enough laws and regulations to ensure fair competition and protect consumers.D) Because it makes the sharing economy too popular.46. What can be inferred about the sharing economy from the passage?A) It will disappear soon.B) It has both positive and negative aspects.C) It is only suitable for developed countries.D) It is a perfect economic model.Passage 2.Questions 47 - 50 are based on the following passage.Cultural heritage is an important part of a nation's identity. It includes historical buildings, artworks, traditions, and languages. Protecting cultural heritage is not only important for preserving anation's past but also for its future development.One of the ways to protect cultural heritage is through restoration. Restoration projects can bring old historical buildings back to life, allowing people to experience the past. For example, the restoration of the Forbidden City in China has made it a popular tourist destination, attracting millions of visitors every year. Another way is through education. By teaching people about their cultural heritage, they can develop a sense of pride and ownership, and be more likely to protect it.However, protecting cultural heritage also faces some challenges. One challenge is the lack of funds. Restoration projects can be very expensive, and many countries may not have enough money to carry out large - scale restoration work. Another challenge is the impact of modernization. As cities develop, some historical buildings may be demolished to make way for new construction.47. What is cultural heritage according to the passage?A) Only historical buildings.B) Only artworks.C) Historical buildings, artworks, traditions, and languages.D) Only modern buildings.48. Why is protecting cultural heritage important?A) Only for preserving a nation's past.B) Only for a nation's future development.C) For both preserving a nation's past and its future development.D) For no particular reason.49.

二、（9分，每小题3分）阅读下面的文字，完成6-8题。
（每小题3分）李白诗歌与盛唐气象周成芳①李白，作为盛唐文化孕育出来的天才诗人，以其非凡的自负和自信，狂傲的独立人格，豪放洒脱的气度和自由创造的浪漫情怀，充分体现了盛唐诗人的时代性格和精神风貌。
②没有盛唐，就不会产生李白。
③天才人物左右不了时代的步伐，恰恰是随时代的推移，才不断有所谓的天才出现。
我们的目标不是用主要天才人物来界定时代，而是用那一时代的实际标准来理解、正视最伟大的诗人。
④从环境、时代的背景出发，伟大的艺术家不是孤立的，而只是一个艺术家家族的杰出代表。
有如百花盛开的园林中的一朵更美艳的花，一株茂盛的植物的“一根最高的枝条”，而在艺术家族背后还有更广大的群众。
⑤唐诗在开元、天宝盛世全面繁荣。
山水田园诗人王维、孟浩然，把山水田园的静谧明秀的美表现得让人心驰神往；边塞诗人高适、岑参，把边塞生活写得瑰奇壮伟、豪情慷慨；后人对此时期的唐诗有许多的评论，概括地说就是骨气端翔，兴象玲珑，无工可见，无迹可求，而含蕴深厚，韵味无穷。
作为这一时期最重要的诗人李白，以其绝世才华，豪放飘逸的气质，把诗写得行云流水，而又变幻莫测，情则滚滚滔滔，美如清水芙蓉。
李白的作品在形式和内容包容了那个时代所拥有的特色，又超越了那个时代，反映了那个时代昂扬的精神状态。
从某种程度上讲，李白的魅力就是盛唐的魅力。
⑥自公元624年唐王朝一统中国，经过太宗、高宗、武则天、玄宗前期一百年的持续发展，唐王朝成为中国历史上政治清明、经济发达、军事强大、文化繁荣的朝代。
国力的强盛，政策的开明为文化的发展提供了强有力的保障。
儒、道、佛三家思想并行发展，这一切为唐人展开了一条宽阔的道路。
盛唐的士子们因此对人生普遍抱有一1种积极、乐观、进取的态度，集自信与狂傲于一身。
在李白身上更具有理想色彩，使其成为盛唐精神的一个标志。
如李白的《客中作》全诗写得豁达开朗、一泻无余，充分体现了李白豪放不羁的个性，并从侧面反映出盛唐时期的时代气氛。
⑦唐代这样一个兴旺发达的社会，生活本身就容易激起人们的诗情，而在时代精神的影响下，这一时期的诗人又往往更多地带着一种诗意的眼光看生活，因而即使是在平常的、习见的生活中也发现了丰富多彩的美。
如李白的《子夜吴歌》：“长安一片月，万户捣衣声。
秋风吹不尽，总是玉关情。
何日平胡虏，良人罢远征。
”《子夜吴歌》为乐府旧题，是六朝时南方著名的情歌，多抒写少女对情人的思念，表达真诚缠绵的爱情。
语言自然清新，明白如话，流丽婉转。
唐诗以前所未有的力量，反映了中国封建社会在他繁荣昌盛时期所呈现出来的生活美，也表现了这样一个时代中人们比较健康昂扬的精神状态。
⑧李白的豪放洒脱的个性魅力在当时不是孤木，不是独一无二的，只是由于他天生的气质融入这个时代更具典型性。
但这不是说否认李白的天才。
他是天才！艺术家需要一种必不可少的天赋，便是天大的苦功天大的耐性也补偿不了的一种天赋，否则只能成为临摹匠与工匠。
正如李白所言，“天生我材必有用”，他的材便是天才诗人的灵感与想象，便是那种天生的独立个性，以及将这个性很好地融入诗歌中的天赋。
当他像石子一样投入雄浑的时代之海里，便引起了巨大的波澜。
6. 下列选项不正确的一项是A.从一定程度上讲，盛唐的魅力就是李白的魅力。
B.李白天生的气质融入这个时代更具典型性，所以他是天才。
C.李白的材便是天才诗人的灵感与想象，便是那种天生的独立个性。
D.唐诗以前所未有的力量，反映了中国封建社会在他繁荣昌盛时期所呈现出来的生活美。
7. 下列对开元、天宝盛世诗歌评价不正确的是A.边塞诗人高适、岑参，把边塞生活写得瑰奇壮伟、豪情慷慨。
B.山水田园诗人王维、孟浩然，把山水田园的静谧明秀的美表现得让人心驰神往。
C.后人对唐诗概括地说就是骨气端翔，兴象玲珑，无工可见，无迹可求，而含蕴深厚，韵味无穷。
D.李白的作品在形式和内容包容了那个时代所拥有的特色，又超越了那个时代，反映了那个时代昂扬的精神状态。
8. 下列对唐朝时代与诗人的关系评价不正确的一项是A.国力的强盛，政策的开明为文化的发展提供了强有力的保障。
盛唐的士子们对人生普遍抱有一种积极、乐观、进取的态度。
B.李白身上自信与狂傲，使其成为盛唐精神的一个标志。
C.《客中作》的明白如话，流丽婉转。
充分体现了李白豪放不羁的个性，并从侧面反映出盛唐时期的时代气氛。
D.在唐朝时代精神的影响下，这一时期的诗人又往往更多地带着一种诗意的眼光看生活。

太傅袁隗欲以女妻范，范辞不受。
性恬静乐道，忽于荣利，征命无所就。
弟承，字公先，亦知名，以方正征，拜议郎，迁伊阙都尉。
董卓作乱，承欲合徒众与天下共诛卓。
承弟昭时为议郎，适从长安来，谓承曰：“今欲诛卓，众寡不敌，且起一朝之谋，战阡陌之民，士不素抚，兵不练习，难以成功。
卓阻兵而无义，固不能久；不若择所归附，待时而动，然后可以如志。
”承然之，乃解印绶间行归家，与范避地扬州。
袁术备礼招请，范称疾不往，术不强屈也。
遣承与相见，术问曰：“昔周室陵迟，则有桓、文之霸；秦失其政，汉接而用之。
今孤以土地之广，士民之众，欲徼福齐桓，拟迹高祖，何如？”承对曰：“在德不在强。
夫能用德以同天下之欲，虽由匹夫之资，而兴霸王之功，不足为难。
若苟僭拟，干时而动，众之所弃，谁能兴之?”术不悦。
是时，太祖将征冀州，术复问曰：“今曹公欲以弊兵数千，敌十万之众，可谓不量力矣!子以为何如?”承乃曰：“汉德虽衰，天命未改，今曹公挟天子以令天下，虽敌百万之众可也。
”术作色不怿，承去之。
太祖平冀州，遣使迎范。
范以疾留彭城，遣承诣太祖，太祖表以为谏议大夫。
范子陵及承子戬为山东贼所得，范直诣贼请二子，贼以陵还范。
范谢曰：“诸君相还儿厚矣。
夫人情虽爱其子，然吾怜戬之小，请以陵易之。
”贼义其言，悉以还范。
太祖自荆州还，范得见于陈，以为议郎，参丞相军事，甚见敬重太祖征伐，常令范及邴原留，与世子居守。
太祖谓文帝：“举动必谘此二人。
”世子执子孙礼。
救恤穷乏，家无所余，中外孤寡皆归焉。
赠遗无所逆，亦终不用，及去，皆以还之。

B．张范让张承去见袁术，由于张承在言谈之中没有曲意逢迎袁术，致使见面不欢而散。
从中可以看出张承“方正”的性格。
C．张范与张承的儿子同被盗贼劫持，张范前往贼穴营救，最终盗贼被他的仁义之言所感动，把两个孩子都还给了他。
D．太祖每当出兵征战，常常让张范和邴原辅助世子曹丕一同留守，并告诫曹丕若有所行动一定要向两人咨询，足见张范深得太祖器重。
