What began as getting outdoors and exploring local hikes 32 a passport stamped with adventures around the world. Like many new hikers, I joined for 33 reasons: motivation to stay active, explore nature and make friends. What I found, however, were fellow hikers who shared trail (徒步路线) knowledge, life stories and an 34 enthusiasm for travel. Conversations sometimes 35 toward overseas experiences and gradually planted seeds. Before long, I began to see a way to 36 my desire to maintain fitness and explore the world. It was challenging at first, as I was still working full‑time, and could only 37 once a year. Nevertheless, I managed to 38 short vacations and visited many striking places. Each subsequent trip brought fresh 39 and helped strengthen my willpower. I learned to navigate routes, something I once thought impossible, 40 unexpected situations and communicate with people from different cultures. I also managed to persuade my husband to 41 me to Northern England. We stayed in inviting inns, passing through rolling hills and ancient villages, 42 by the beautiful scenery. Then we booked a tour to South America where we explored Patagonia. This was perhaps the most 43 of them all, with its towering peaks, fierce winds and interesting wildlife viewing. Even though our itinerary (行程表) 44 bus travel to take us from one hiking destination to another, we were required to travel on foot, dragging our suitcases behind us. It certainly 45 an experience none of us will ever forget. Along the way, my growing love of active travel led to even more adventures. These journeys 46 physical challenge with cultural immersion. Hiking friends also introduced me to backpacking, and a new passion 47. What stands out most is how a hiking club served as a catalyst (催化剂). It did more than maintain trails; it fostered a sense of 48 and joy. Looking back, I may have joined for fitness and fresh air, but I stayed for the people. Through organized activities and shared 49, club members learn not only about the trails beneath their feet but also about themselves. One trail led to another, and before I knew it, the path 50 across countries and continents. All it took was that first step. 31. A. transfer B. reshape C. claim D. bother 32. A. picked up B. got across C. grew into D. tuned in 33. A. personal B. dramatic C. collective D. practical 34. A. infectious B. ordinary C. confusing D. sudden 35. A. shifted B. led C. pointed D. rushed 36. A. guide B. follow C. fulfill D. register 37. A. go through B. get away C. live apart D. pull over 38. A. compose B. dismiss C. arrange D. deliver 39. A. patience B. insights C. enquiry D. repetition 40. A. handle B. seek C. observe D. escape 41. A. remind B. approach C. represent D. accompany 42. A. drawn B. identified C. deafened D. integrated 43. A. heart‑racing B. awe‑inspiring C. energy‑saving D. brain‑washing 44. A. created B. replaced C. included D. performed 45. A. gave away B. left out C. saw through D. made for 46. A. combined B. meant C. revealed D. swept 47. A. held promise B. took root C. worked wonders D. gained ground 48. A. administration B. possibility C. possession D. suspension 49. A. companionship B. procedure C. identity D. qualification 50. A. withdrew B. stretched C. distinguished D. approached 四、阅读理解：本大题共20小题，每小题2.5分共50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。 A There’s no better way to successfully learn a foreign language than to immerse (使沉浸) yourself in its culture.

Watching a man walk every street in New‑York made my friend Martha and me want to do the same thing in the heart of our own‑hometown. Besides, Kingston is considered the most walkable city in Ontario, Canada. So, armed with nothing but a massive book of street maps, we set out to walk a minimum of 10 kilometers every Saturday until we’d covered every paved bend and dead‑end street. Our 542.4‑kilometer journey began on Sept 1, 2021. As keen walkers, we weren’t worried about the distance. We loved the idea of discovering parts of the city we had never seen. Every yard offered a quick look into the personality of those who owned it. Some yards overflowed with apple trees bending under the weight of fruit. Others were covered with bits of painted wood and broken metal. But more than the scenery and steps taken, the biggest discovery was the questions, the sharp observations and the thoughtful conversations shared between us. Hidden parts were uncovered as we walked and talked. I admitted my fondness for romance novels and blow‑up Santas. Martha revealed her strong interest in tiny free libraries. “How are we even friends?” she joked one day. Maybe it’s because, for both of us, walking helps us stay balanced. There is a calming joy in hitting the pavement; along with an ease of conversation that comes without the face‑to‑face pressure that can prevent closeness. With every footstep, we became better listeners and our friendship grew. Of course, as winter set in, there were some days we longed to stay under the covers, but what had started as a lighthearted project had grown into something precious, a meet‑up vital to our mental and physical well‑being. And our deep conversations remained private. What happened on the pavement stayed on the pavement. Three years and six pairs of shoes later, we had walked the 542.4 kilometers. Forever changed by what started as a “what‑if” project and now full of confidence, we are already planning our next big walking adventure. As long as we are able, we’ll keep pulling ourselves out of bed to put one foot in front of the other. In doing so, we’ll keep discovering not just ourselves, but each other as well. 56. What inspired the author and Martha to start their walking project? A. A map book showing all roads in Kingston. B. Their desire to explore Ontario’s urban streets. C. A film about a New York street‑walking challenge. D. Kingston’s reputation as Ontario’s top walking city. 57. What did the author value most about their weekly walks? A. The chance to see different types of yards. B. The mix of natural scenery and urban elements. C. The physical exercise from long‑distance walking. D. The deep talks and careful observations they shared. 58. Why does the author mention their discussions about “romance novels” and “tiny free libraries”? A. To show they had similar tastes in books. B. To describe arguments about their hobbies. C. To prove their friendship was built on reading. D. To explain how walking made them more open. 59. What can be learned about the walking project in winter? A. They sometimes wanted to skip walking due to cold weather. B. They recorded their conversations to keep memories. C. They added more distance to their weekly goal. D. They invited new friends to join their walks. 60. What is the main purpose of the last paragraph? A. To describe future walking plans. B. To explain ending the current journey. C. To emphasize the project’s lasting impact. D. To compare past and present attitudes toward walking. C With the fast development of astronomy, astronomers are eager to find a clue of the familiar: planets that are like Earth. By pushing technology to the limits, astronomers are rapidly approaching the day when they can find another Earth. The most direct approach is to take a picture of it with a telescope. However, a more effective way is to use “the Doppler technique”. This involves analyzing starlight for evidence that the moving Position of the star is affected by the gravity of a planet. Nowadays, astronomers can tell when a planet is pulling its star by only one meter a second — about‑human walking speed. That’s enough to detect a giant planet in a big orbit, or a small planet if it’s close to its star. Another approach is to watch a star for a slight drop in its brightness. This occurs when an orbiting planet passes in front of the star and blocks part of its light. At most a tenth of all planetary systems are oriented so that these mini‑eclipses (迷你日食) — called transits (凌日)— are visible from Earth. So, astronomers must monitor a lot of stars to catch just a few transits. The dream of astronomers is to discover a rocky planet roughly the size of Earth orbiting in a habitable zone, one that is neither too hot nor too cold to support life. If they succeed, they will have found what biologists believe could be a promising residence for life. The best places to look may be dwarf stars (矮星). Smaller than the sun, dwarf stars are plentiful; seven of the ten stars nearest to Earth are dwarf stars. They also provide a steady supply of sunlight to any life‑bearing planets within their habitable zone. Additionally, dwarf stars are dim (暗淡的), so the habitable zone lies closer in. If the planet is closer to the star, it’s easier for astronomers to detect a transit observation. A close‑in planet also has a stronger pull on its star. That makes it easier to detect with the Doppler method. 61. According to paragraph 2, astronomers analyze starlight with the aim of finding ________. A. where we can detect a giant orbit B. why a small planet is close to its stars C. how strong the power of the gravity is D. whether the movement of the stars is changed 62. Why do astronomers have to monitor a lot of stars to capture transits? A. Transits last a very short period. B. Most planetary systems don’t have transits. C. Transits only occur for a small number of stars. D. Not more than 10% planetary systems have visible transits from Earth. 63. The word “habitable” in paragraph 4 most likely means ________. A. livable B. adjustable C. sustainable D. visible 64. Dwarf stars may be good places to spot Earth‑like planets because ________. A. dwarf stars are limited in number B. their planets are close to the Earth C. the closeness of the habitable zone to dwarf stars aids detection D. the brightness of dwarf stars to Earth improves their visibility 65. What is the main purpose of the text? A. To describe planet‑finding processes. B. To inform readers of planet‑finding methods. C. To promote space tools used to find habitable planets. D. To argue that human beings can soon find habitable planets. D Psychologists have long been in disagreement as to whether competition is a learned or a genetic component of human behavior. Whatever it is, you cannot but recognize the effect competition is exerting in academics and many other areas of contemporary life. Psychologically speaking, competition has been seen as an inevitable consequence of human drives. According to Sigmund Freud, humans are born screaming for attention and full of organic drives for fulfillment in various areas. Initially, we compete for the attention of our parents. Thereafter, we are at the mercy of a battle between our base impulses for self‑fulfillment and social and cultural norms which prohibit pure indulgence. Current work in anthropology (人类学) has suggested,however,that this view of the role of competition in human behavior may be incorrect. Thomas Hobbes, one of the great philosophers of the seventeenth century, is perhaps best remembered for his characterization of the “natural world,” that is, the world before the imposition of the will of humanity, as being “nasty, brutish, and short.” This image of the pre‑rational world is still widely held, reinforced by Charles Darwin’s highly influential work, The Origin of Species, which established the doctrine of natural selection. This doctrine, which takes for granted that those species best able to adapt to and master the natural environment in which they live will survive, has suggested that the struggle for survival is an inherent human trait which determines a person’s success. Darwin’s theory has even been summarized as “survival of the fittest” — a phrase Darwin himself never used‑further highlighting the competition’s role in success. As it has often been pointed out, however, there is nothing in the concept of natural selection that suggests that competition is the most successful strategy for “survival of the fittest.” Darwin asserted in The Origin of Species that the struggles he was describing should be viewed as metaphors and could easily include dependence and cooperation. Many studies have been conducted to test the importance placed on competition as opposed to other values, such as cooperation — by various cultures, and generally conclude that Americans uniquely praise competition as natural, inevitable, and desirable. In 1937, the world‑renowned anthropologist Margaret Mead published Cooperation and Competition among Primitive Peoples, based on her studies of several societies that did not prize competition, and, in fact, seemed at times to place a negative value on it. One such society was the Zuni Indians of Arizona, and they, Mead found, valued cooperation far more than competition. After studying dozens of such cultures, Mead’s final conclusion was that competitiveness is a culturally created aspect of human behavior, and that its prevalence in a particular society is relative to how that society values it. 66. What does the author think is easy to see in many areas of contemporary life? A. The disagreement on the inevitability of competition. B. The consequence of psychological investigation. C. The effect of human drives. D. The impact of competition. 67. According to psychology, what do people strive to do following the initial stage of their life? A. Fulfill individual needs without incurring adverse effects of human drives. B. Indulge in cultural pursuits while keeping their base impulses at bay. C. Gain extensive recognition without exposing pure indulgence. D. Satisfy their own desires while observing social conventions. 68. What do we learn about the “natural world” characterized by Thomas Hobbes? A. It gets misrepresented by philosophers and anthropologists. B. It gets distorted in Darwin’s The Origin of Species. C. It is free from the rational intervention of humans. D. It is the pre‑rational world rarely appreciated nowadays. 69. What can we conclude from Darwin’s assertion in The Origin of Species? A. All species inherently depend on others for survival. B. Struggles for survival do not exclude mutual support. C. Competition weighs as much as cooperation as a survival strategy. D. The strongest species proves to be the fittest in natural selection. 70. What conclusion did Margaret Mead reach after studying dozens of different cultures? A. It is characteristic of humans to be competitive. B. Americans are uniquely opposed to cooperation. C. Competition is relatively more prevalent in Western societies. D. People’s attitude towards competition is actually culture‑bound. 第Ⅱ卷 非选择题（共35分） 五、阅读表达：本大题共5小题，每小题2分，共10分。 My love for animals began through watching wildlife documentaries when I was a kid. I went on to study Environmental Science at university, and became interested in marine (海洋的) biology when I did my master’s degree. That’s when I realised that there was a possibility to do more for Hong Kong. In Hong Kong, many people would associate marine life only with seafood, and few people would consider it as a part of nature to be appreciated. Although our marine life is highly diverse, our waters have been overfished for more than 40 years. Records show that, decades ago, Hong Kong had such high production of seafood that it supported about 90% of the local demand. Today, at least 90% of the seafood we eat has to be imported to meet local demand, as our waters are so overfished that they can no longer support the local appetite. Despite this shift, we are still a city in love with seafood — according to the Food and Agriculture Organization of the United Nations, Hong Kong has the second highest annual seafood consumption per capita (人均) in Asia — but consumers are barely aware of where their seafood comes from and which species are threatened. There is a lot of room for improvement in Hong Kong. Improving local fishery management policies and increasing the coverage of Marine Protected Areas, as well as conducting the relevant research to inform decisions, could move the city towards greater sustainability in this area. And consumers should avoid eating seafood that is on the threatened species list. As a general rule of thumb, if people are not sure what the species is, they should choose something else that they are more familiar with. With the marine ecosystem already weak and easily destroyed, the greatest threat is continued ignorance and inaction. It is time for us to show that we can also be part of the solution. If each person plays their part — even for just one meal a day — Hong Kong would already be on its way to making considerable progress towards sustainable seafood consumption. 71. According to the passage, what is the main problem in Hong Kong now? (no more than 5 words) 72. What does the underlined word in Paragraph 3 mean? (1 word) 73. What is the main idea of Paragraph 4? (no more than 10 words) 74. What is the greatest threat to the marine ecosystem in Hong Kong? (no more than 6 words) 75. Do you support avoiding threatened seafood species? Why? (no more than 20 words)  六、书面表达：本大题共1小题，共25分。 76. 假设你是晨光中学的李津。在某英语学习论坛上，你看到一则关于“Healthy Screen Time”的讨论，帖子里还附上了下方关于学生周末屏幕使用时间的调查图表。请你跟帖，根据图表信息，表达你的看法。 内容包括： 1. 描述图表反映的主要现象； 2. 分析过度屏幕娱乐可能带来的问题； 3. 提出一到两条合理使用屏幕的建议。 要求： 1. 词数不少于100字； 2. 可适当加入细节，使内容充实、行文连贯。 学科网（北京）股份有限公司 $
