Fergus, your particular concern is the future of fishing. M: That’s right. We want more people to know what fish they’re eating. According to some researchers, 90% of the fish populations have gone, worse than the situation 50 years ago. But some fish populations can grow quite quickly if they are protected properly. W: I’m quite worried about the condition of some of the fish I see in supermarkets. M: I know what you mean. We’ve recently started using electronic devices to track fish as they move from the oceans to the markets. This helps us check the quality, and this is important when it comes to threatened species. W: That’s meaningful. But is it easy to encourage consumers to buy fish that have been caught in an eco-friendly way? M: I am confident that many customers do worry about our oceans. They won’t mind paying a little bit more for this kind of fish. We do believe that we can sell these fish at a price that customers can afford. （本题4.5分）听下面一段独白，回答以下小题。 18．(1.5分)Who is the speaker talking to? A．A group of students. B．A group of zoo keepers. C．A group of climate scientists. 19．(1.5分)How many polar bears will be left if no action is taken? A．About 13,000. B．About 26,000. C．About 39,000. 20．(1.5分)What is the speech mainly about? A．The threats polar bears face. B．The effects of climate change. C．The interactions between humans and polar bears. 【答案】18．A 19．A 20．A 【原文】W: Thank you all for coming. I know you’re all busy with your final examinations and I appreciate you being here today. So, what do you think when you hear the words “climate change”? What comes to my mind first is the polar bear. There are about 26,000 polar bears worldwide. A study suggests that their numbers may fall by about 50% if no action is taken. Polar bears are facing many pressures. The biggest pressure is the loss of sea ice habitat. Climate change damages the sea ice, which polar bears depend on for survival. And as the interactions between humans and polar bears become more common, people are more likely to kill them in self-defense. Besides, industrial development means more oil production in the Arctic. Contact with oil can kill polar bears. Everyone has a part to play in preventing polar bears from disappearing. You can, for example, use less electricity and petrol. 二、阅读理解 Become a Guggenheim Member Today!

On March 23, people first saw it trapped on a sandbank near the city of Luebeck. It managed to free itself but then became stuck again several times. Finally, on a Saturday morning, after weeks of effort, the whale was released into the North Sea off the coast of Denmark. It had been carried on a large flat boat called a barge. A member of the rescue team said the whale left the barge at around 8:45 am and was now swimming on its own, freely, and in the right direction. The rescue team members cheered as they watched Timmy disappear into the deep water. However, the rescue effort was anything but easy. The whale’s long struggle attracted a lot of media attention. TV channels, websites, and social media influencers covered the story non-stop. At the beginning of April, German officials had given up trying to save the whale. They believed the animal was too weak and could not survive. However, many people were very upset about this decision. They wrote letters, called officials, and expressed their anger on social media. Two wealthy businessmen then proposed a private rescue plan. After strong public pressure, the government finally agreed to let them try. The rescuers first tried using inflatable cushions and floating platforms, but that did not work. The whale was too large and the water too shallow. Then they came up with the idea of using a barge to transport the whale to deeper water. Many experts criticized the plan, saying it would only cause the whale more pain and stress. The rescue effort was seen as unlikely to succeed. But the rescue team decided to go ahead anyway. Fortunately, the rescue was a success. Timmy was set free and swam away. 24．(2.5分)What happened to the whale at first? A．It was hit by a large boat. B．It was caught off the coast. C．It was saved by German officials. D．It was released into the North Sea. 25．(2.5分)How did the public feel about the whale? A．Concerned. B．Uncaring. C．Disappointed. D．Hopeful. 26．(2.5分)What can we learn from the last two paragraphs? A．Media attention postponed the rescue. B．The whale got hurt during the rescue. C．The rescue process was not smooth. D．The rescue was funded by the public. 27．(2.5分)What is the best title for the passage? A．Practical Ways to Save a Whale B．Timmy the Whale: A Cry for Help C．The Secret Life of a Humpback Whale D．Timmy the Whale: An Eventful Rescue 【答案】24．B 25．A 26．C 27．D 【导语】本文主要讲述一头名叫Timmy的座头鲸在德国海岸搁浅，历经重重波折，最终依靠民间私人救援方案成功获救并被放归北海的故事。 【详解】24．细节理解题。根据第一段中的“On March 23, people first saw it trapped on a sandbank near the city of Luebeck.(3月23日，人们第一次发现它被困在吕贝克市附近的沙洲上)”可知，这头鲸鱼一开始被困在海岸附近。 25．推理判断题。根据第三段中的“However, many people were very upset about this decision. They wrote letters, called officials, and expressed their anger on social media.(然而，许多人对这一决定感到非常难过。他们写信、致电官员，并在社交媒体上表达愤怒)”以及“After strong public pressure, the government finally agreed to let them try.(在强大的公众压力下，政府最终同意让他们尝试)”可知，公众对鲸鱼的命运非常关切，并积极发声。A选项“Concerned(关切的)”准确描述了公众的态度。 26．推理判断题。根据第三段中的“At the beginning of April, German officials had given up trying to save the whale.(四月初德国官员已经放弃营救鲸鱼)” 以及最后一段中的“The rescuers first tried using inflatable cushions and floating platforms, but that did not work. The whale was too large and the water too shallow. Then they came up with the idea of using a barge to transport the whale to deeper water. Many experts criticized the plan, saying it would only cause the whale more pain and stress. The rescue effort was seen as unlikely to succeed.(救援人员最初尝试使用充气垫和漂浮平台，但未能奏效。鲸鱼体型过大，且水深不足。随后他们想到用驳船将鲸鱼运送到更深的水域。许多专家批评这一计划，认为只会让鲸鱼承受更大的痛苦和压力。救援行动被认为几乎不可能成功)”可知，救援过程一波三折，并非一帆风顺。C选项“The rescue process was not smooth.(救援过程并不顺利)”是对这两段内容的准确概括。 27．主旨大意题。文章围绕名为Timmy的鲸鱼展开，详细叙述了它从搁浅、多次被困、官方放弃、公众抗议、私人营救到最终成功回归大海的一系列曲折事件。D选项“Timmy the Whale: An Eventful Rescue(鲸鱼蒂米：一场多舛的救援)”准确概括了文章的核心内容与戏剧性过程，适合作为标题。 （本题10分）Local volunteer groups have become an important driving force for ecological protection on the Qinghai-Tibet Plateau (高原). Many people have the wrong idea that wildlife protection only means saving one rare animal. In fact, real ecosystem protection refers to protecting whole food chains and natural habitats. A healthy ecosystem means a balance among plants, animals, and tiny living things that break down waste. Losing even one small part can cause big problems. Volunteers in high areas do many practical field tasks. They walk into rivers to pick up floating rubbish, often filling many bags each time. They keep records of wild animal movements, writing down the types, numbers, and places. They also remove harmful plants that grow too fast and hurt local plants. Most of these volunteers are local people. They know the land well and understand seasonal changes, so they are good at outdoor work. Before they start, they receive training from environmental researchers. They learn how to recognize different animals and plants and how to use simple tools. Working on the plateau is physically hard. The air is thin above 4,000 meters, so even walking feels tiring. Strong sunlight can hurt skin quickly. Cold winds blow often, especially in winter. But their work does not try to make fast changes. Instead, they focus on long-term watching and slow improvement. Some projects may take years to show clear results. Local people combine their old knowledge with modern protection methods. For example, they use traditional ways of raising farm animals to avoid disturbing wildlife when they have babies. Experts say that community-led volunteer work is a useful addition to government protection programs. Government teams often work in large nature reserves, while local volunteers help in smaller, faraway places. When locals and researchers work together, they get better results for the plateau’s fragile environment. 28．(2.5分)How does the author explain “a healthy ecosystem” in Paragraph 1? A．By giving a typical example. B．By giving a clear definition. C．By telling a detailed story. D．By comparing diverse ideas. 29．(2.5分)What makes local people good at field work? A．They have modern tools. B．They work for the government. C．They receive a high pay. D．They know the land and seasons. 30．(2.5分)What does Paragraph 3 mainly talk about? A．The training volunteers receive. B．The beauty of the plateau land. C．The challenges volunteers face. D．The fast results of their work. 31．(2.5分)What’s the best structure of the passage? A．Clarification → Actions → Difficulties → Significance B．Concept → Examples → Comparison → Prediction C．Background → Story → Analysis → Suggestion D．Problem → Practices → Examples → Solution 【答案】28．B 29．D 30．C 31．A 【导语】主要介绍青藏高原当地志愿者团队开展生态保护工作，包括理念、行动、困难与价值。 【详解】28．推理判断题。根据第一段中的“A healthy ecosystem means a balance among plants, animals, and tiny living things that break down waste.(健康的生态系统指植物、动物以及分解废弃物的微小生物之间的平衡。)”可知，作者通过下定义的方式解释健康的生态系统。 29．细节理解题。根据第二段中的“Most of these volunteers are local people. They know the land well and understand seasonal changes, so they are good at outdoor work.(这些志愿者大多是当地人。他们熟悉这片土地，了解季节变化，因此擅长野外工作。)”可知，当地人熟悉土地与季节变化，所以擅长野外工作。 30．主旨大意题。根据第三段中的“Working on the plateau is physically hard. The air is thin above 4,000 meters, so even walking feels tiring. Strong sunlight can hurt skin quickly. Cold winds blow often, especially in winter.(在高原工作体力消耗很大。海拔4000米以上空气稀薄，就连走路都觉得疲惫。强烈的阳光会很快灼伤皮肤，寒风常年肆虐，冬季尤甚。)”可知，本段主要讲述志愿者面临的各种挑战。 31．推理判断题。第一段：阐释生态保护理念（概念澄清 Clarification）；第二段：志愿者开展的各类保护行动（Actions）；第三段：高原工作面临的困难（Difficulties）；第四段：社区志愿工作的意义与价值（Significance）。文章结构：理念阐释 → 保护行动 → 面临困难 → 工作意义。 （本题10分）A new study sheds light on how methane (甲烷) is produced in the open ocean. Researchers at the University of Rochester identified the process could grow stronger as global temperatures rise. Methane is a powerful greenhouse gas, yet scientists have long been puzzled by an unusual pattern. Surface ocean waters regularly release methane into the atmosphere, even though these waters contain plenty of oxygen. Traditionally, methane formation has been linked to environments without oxygen, such as wetlands or deep ocean sediments. To better understand this contradiction, the research team combined global data with computer simulations. They found that certain microbes (微生物) can produce methane as they break down organic material, but only when phosphate, a key nutrient, is in short supply. This discovery changes how scientists view methane production in marine environments. The study also highlights how climate change could influence this process in the future. As the ocean warms, the difference in density between surface water and deeper layers increases. This is expected to slow the upward and downward mixing that carries nutrients like phosphate up from depth. With less mixing, fewer nutrients reach the surface. The team’s model shows that this could leave surface waters increasingly depleted of phosphate, creating favorable conditions for methane-producing microbes. If methane production rises, more of this gas could escape into the atmosphere. Because methane is so effective at trapping heat, this creates the risk of an intensifying cycle: Warmer oceans lead to higher methane emission, which then contributes to further warming. Importantly, this cycle mechanism is not yet included in most major climate models. As scientists work to improve predictions, accounting for processes like this may be crucial for understanding how quickly climate change will progress. “Our work will help fill a key gap in climate prediction, which often ignores interactions between the changing environment and natural greenhouse gas sources to the atmosphere,” says Thomas Weber, one member of the research team. 32．(2.5分)What puzzled scientists about methane in the open ocean? A．It is produced in deep ocean. B．It is fading in trapping heat. C．It arises in oxygen-rich water. D．It speeds up ocean warming. 33．(2.5分)What does the underlined word “depleted” in paragraph 4 mean? A．Warned. B．Composed. C．Accused. D．Starved. 34．(2.5分)What can be inferred about the cycle mentioned in paragraph 5? A．It relies on sufficient phosphate. B．It could speed up global warming. C．It is included in most climate models. D．It weakens methane’s warming effect. 35．(2.5分)What does Thomas Weber think of their discovery? A．It applies to specific ocean regions. B．It’s a missing link in climate models. C．It’s a result based on ideal conditions. D．It works in controlling climate change. 【答案】32．C 33．D 34．B 35．B 【导语】文章主要介绍了一项关于海洋甲烷生成的全新研究，解开了含氧表层海水释放甲烷的科学矛盾，阐释海洋升温会减少表层磷酸盐、催生产甲烷微生物，形成加剧变暖的循环，同时说明该机制尚未纳入主流气候模型，此项研究填补气候预测的空白。 【详解】32．细节理解题。根据第二段“Methane is a powerful greenhouse gas, yet scientists have long been puzzled by an unusual pattern. Surface ocean waters regularly release methane into the atmosphere, even though these waters contain plenty of oxygen. (甲烷是强效温室气体，但长期以来科学家都对一种反常现象感到困惑：即使海洋表层水体富含氧气，却持续向大气释放甲烷。)”可知，让科学家困惑的是甲烷在富氧水体中产生。 33．词句猜测题。根据第四段“This is expected to slow the upward and downward mixing that carries nutrients like phosphate up from depth. With less mixing, fewer nutrients reach the surface. The team’s model shows that this could leave surface waters increasingly depleted of phosphate, creating favorable conditions for methane-producing microbes. (预计这会减缓海水上下对流，而这种对流能将磷酸盐等营养物质从深海带到表层。对流减弱后，抵达表层的营养物质会变少。该研究团队的模型显示，这会使表层海水中的磷酸盐愈发depleted，为产甲烷微生物创造适宜生存的环境。)”可知，前文提到磷酸盐供给不足会催生产甲烷微生物，推断depleted表示“匮乏，短缺”，与D选项“Starved.(匮乏的)”含义相近。 34．推理判断题。根据第五段“Because methane is so effective at trapping heat, this creates the risk of an intensifying cycle: Warmer oceans lead to higher methane emission, which then contributes to further warming. (因甲烷储热能力极强，造成恶性循环的风险：海洋升温会提升甲烷排放量，甲烷又会进一步加剧全球变暖。)”可知，该循环会加快全球变暖进程。 35．细节理解题。根据最后一段“‘Our work will help fill a key gap in climate prediction, which often ignores interactions between the changing environment and natural greenhouse gas sources to the atmosphere,’ says Thomas Weber, one member of the research team. (研究团队成员Thomas Weber表示：‘我们的研究将填补气候预测中的关键空白，现有预测往往忽视环境变化与天然温室气体排放之间的关联。’)”可知，他认为这项发现弥补了气候模型缺失的关键环节。 （本题12.5分）Finding Nemo just got trickier. Why? Because it looks like clownfish are shrinking. The colourful fish, made famous by the popular animated film, can quickly reduce their size as a way to deal with heat stress, a study in Science Advances suggests. 36(2.5分) Researchers studied 67 pairs of clownfish living in reefs off Kimbe Bay in Papua New Guinea during the marine heatwave of 2023. 37(2.5分) Adult clownfish grow to be about 8cm long but these animals lost a couple of millimetres in the space of a few months. “This is not just about getting skinnier under stressful conditions, these fish are actually getting shorter,” says Melissa Versteeg. It’s well known that animals can evolve to become smaller over generations. 38(2.5分) For example, some fish on remote islands gradually shrink in size. But these are evolutionary changes that occur across hundreds of years. It may not sound it but this rapid response is actually good for the fish. Shrinking increased individuals’ chances of surviving the heatwave by as much as 78 per cent, the team found. 39(2.5分) We don’t yet know if other fish species are also shrinking during heatwaves but, if they are, it could explain a bigger trend: many ocean fish are getting smaller. Other explanations include pollution, habitat degradation, overfishing and food web disruptions. 40(2.5分) A．They measured the fish every month for five months and found 75% shrank. B．The study also solves the problem of worldwide overfishing in the oceans. C．This finding may explain why fish worldwide are becoming smaller in warmer seas. D．Island dwarfism is a typical case caused by limited resources on islands. E．Marine heatwaves are becoming more frequent as global temperatures rise. F．Many cartoon characters are based on lovely sea animals like clownfish. G．So this rapid shrinking could be a key new explanation for smaller fish. 【答案】36．C 37．A 38．D 39．E 40．G 【导语】介绍研究发现海葵鱼（小丑鱼）遭遇海洋热浪时会快速体型缩小以应对高温压力，并分析这种快速变小的现象、与长期进化变小的区别、生存意义以及对全球海洋鱼类体型变小趋势的解释。 【详解】36．根据上文 “The colourful fish, made famous by the popular animated film, can quickly reduce their size as a way to deal with heat stress, a study in Science Advances suggests.(一项发表在《科学进展》期刊上的研究表明： 这种因热门动画电影而闻名的彩色鱼类，能够快速缩小自身体型，以此来应对高温带来的生存压力)” 可知，空格处说明这一发现的意义。C选项 “This finding may explain why fish worldwide are becoming smaller in warmer seas.(这一发现或许能解释为何全球变暖海域的鱼类体型正在变小)” 承接上文，符合语境。 37．根据上文“Researchers studied 67 pairs of clownfish living in reefs off Kimbe Bay in Papua New Guinea during the marine heatwave of 2023.(研究人员在2023年海洋热浪期间，对巴布亚新几内亚金贝湾海域珊瑚礁中的67对小丑鱼展开了研究)” 可知，空格处介绍研究过程和得出的结果。A 选项 “They measured the fish every month for five months and found 75% shrank.(他们连续五个月每月测量，发现75%的小丑鱼体型变小)” 承接上文，符合语境。 38．根据下文 “For example, some fish on remote islands gradually shrink in size.(例如，偏远岛屿的鱼类会逐渐变小)” 可知，空格处举例说明岛屿侏儒化这种世代进化变小的典型情况。D 选项 “Island dwarfism is a typical case caused by limited resources on islands.(岛屿侏儒化是因岛屿资源有限而形成的典型案例)” 引出下文举例，符合语境。 39．根据上文 “Shrinking increased individuals’chances of surviving the heatwave by as much as 78 per cent, the team found.(研究小组发现，体型缩小让小丑鱼在热浪中的存活率提升78%)” 可知，空格处说明全球升温背景下海洋热浪愈发频繁。E 选项 “Marine heatwaves are becoming more frequent as global temperatures rise.（随着全球气温升高，海洋热浪愈发频繁）” 承接上下文，符合语境 40．根据上文 “Other explanations include pollution, habitat degradation, overfishing and food web disruptions.(鱼类变小还有污染、栖息地破坏、过度捕捞等其他原因)” 可知，空格处总结小丑鱼快速缩小这一现象。G 选项 “So this rapid shrinking could be a key new explanation for smaller fish.(所以这种快速体型缩小可能是鱼类变小的一个关键新解释)” 承接上文，符合语境。 三、完形填空 （本题15分）It was an October afternoon on the coast when the Marine Mammal Center got a call on its public hotline. There were 41 cries coming from the freezing waters in Morro Bay. The center’s experts were able to 42 that the calls — which sounded almost like a human baby screaming — were coming from a(n) 43 2-week-old sea otter (獭) pup (幼崽) that had been separated from its mother. That could be 44 for the young sea otter and it could die, according to Shayla Zink, who works at the center. “That pup is really 45 everything it learns from the mother to be able to survive in the ocean,” Zink said. The employees at the center jumped into action without 46 . First, they put the baby otter, whom they named “Caterpillar,” into a safe container where it wouldn’t overheat. Then, they recorded the 47 of the pup’s frightened cries. The plan was to 48 the mother towards the boat by broadcasting the pup’s cries through a Bluetooth speaker.

When you think of a fearsome hunter, images of lions and sharks may spring 56(1.5分) mind. Recent research by 57(1.5分) (environment) scientists, however, shows that in fact, humans are the most fearsome hunters 58(1.5分) have the greatest impact on animal populations. In the last 500 years, over 300 species of animals 59(1.5分) (go) extinct. Some activities, such as hunting and fishing, 60(1.5分) (direct) harm animals, while other activities, such as development in towns and cities, impact indirectly on animal populations. Hunting and fishing have influenced the world’s animal populations. Some people hunt animals for food: whale meat 61(1.5分) (eat) in some parts of the world. Some people hunt animals for fashion: animal skin is used to make coats and bags. Still others hunt animals just for fun: deer are tracked 62(1.5分) shot by people who enjoy the excitement of the sport. Human activities that have indirect effects on animals can be just as harmful. When we build farms or factories, we destroy animal habitats and leave many animals with nowhere 63(1.5分) (live), or no food to eat. We can also put animals in danger without ever entering their habitats. Air, water, noise and light pollution can all have a deep and 64(1.5分) (damage) influence quite far from their source. Partly due to pollution 65(1.5分) (cause) by ship traffic and other human activities, the dolphin population has dropped greatly. As the human population continues to grow, so does the effect we have on animals. 【答案】 56．to 57．environmental 58．who/that 59．have gone 60．directly 61．is eaten 62．and 63．to live 64．damaging 65．caused 【导语】文章指出人类活动对动物种群造成了巨大危害，人类才是最可怕的猎手；随着人口增长，这种影响还在不断加剧，已导致大量物种灭绝。 【详解】56．考查介词。句意：当你想到可怕的猎手时，脑海中可能会浮现狮子和鲨鱼的形象。结合“spring”和“mind”可知，此处应用固定短语spring to mind，意为“突然出现在脑海中”。 57．考查形容词。句意：然而，环境科学家的最新研究表明，事实上人类才是最可怕的猎手，对动物种群的影响最大。空处作修饰scientists的定语，形容词environmental符合题意，意为“环境的”。 58．考查定语从句。句意：然而，环境科学家的最新研究表明，事实上人类才是最可怕的猎手，对动物种群的影响最大。空处引导限制性定语从句，修饰先行词hunters，先行词指人，在从句中作主语，应用关系代词who或that作引导词。 59．考查动词时态和主谓一致。句意：在过去500年里，有超过300种动物已经灭绝。空处作句子的谓语，时间状语“In the last 500 years”常与现在完成时连用，且主语over 300 species of animals是复数，助动词应用have。 60．考查副词。句意：一些活动，比如狩猎和捕鱼，直接伤害动物；而另一些活动，比如城镇和城市开发，则间接影响动物种群。空处修饰动词harm，结合后面的“indirectly”可知，副词directly符合题意，意为“直接地”。 61．考查动词时态、语态和主谓一致。句意：有些人为了食物而捕猎动物：在世界上某些地方，鲸鱼肉被食用。空处作句子的谓语，此处在描述一般事实，用一般现在时，eat“吃”和主语whale meat之间是被动关系，应用被动语态，且主语是不可数名词，be动词应用is。 62．考查连词。句意：还有些人只是为了娱乐而捕猎动物：鹿被那些享受运动刺激的人追踪并射杀。空处连接前后两个动作tracked和shot，两者之间是顺承关系，应用并列连词and。 63．考查非谓语动词。句意：当我们建造农场或工厂时，我们破坏了动物的栖息地，使许多动物无处可住，或无食物可吃。结合后面的“or no food to eat”可知，此处是平行结构，空处应用不定式短语to live作定语修饰nowhere。 64．考查形容词。句意：空气、水、噪音和光污染都能在远离其源头的地方产生深远而具有破坏性的影响。空处和deep并列，作修饰influence的定语，形容词damaging符合题意，意为“有破坏性的”。 65．考查非谓语动词。句意：部分由于船只交通和其他人类活动造成的污染，海豚数量已大幅下降。句子已有谓语，空处是非谓语，作pollution的后置定语，cause“造成”和pollution逻辑上是被动关系，因此用过去分词形式caused。 五、书信写作 66．（本题15分）当今，绿色生活已日益成为人们的共识。你校英文报正在开展以“Green Life at Home”为题的征文活动。请你用英语写一篇短文投稿，内容包括： 1、绿色生活的重要性； 2、你的做法； 3、你的倡议。 注意：(1)写作词数应为 80 个左右。 (2)请按如下格式在答题卡的相应位置作答。 Green Life at Home ________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ 【答案】参考答案： Green Life at Home     Green living is essential for saving resources and reducing pollution.

He smoked after meals, while working, and even when he rested at home. Every time he lit a cigarette, thin white smoke filled the room, leaving a strong, unpleasant smell on his clothes and hair. Helen had long disliked her father’s smoking habit. She learned from her teacher that smoking was really harmful to people’s health. It could hurt the lungs, cause bad coughs and even lead to serious illnesses. What worried Helen most was that her father often coughed badly at night. Besides, second-hand smoke was also bad for the whole family’s health. She had tried to ask her father to give up smoking many times, but Jason always shook his head and said it was too hard for him to stop. One Sunday afternoon, Helen saw her father smoking again in the yard. He looked tired after a whole week’s work. Helen walked over quietly and did not blame (责怪) him at once. Instead, she sat beside him and talked with him gently. She told her father how worried she was about his health. She said she hoped her father could accompany (陪伴) her to grow up. To encourage her father, Helen prepared a small notebook. She planned to record every day when her father did not smoke. She also promised to give him a small gift if he could keep not smoking for a month. Jason looked at his daughter’s sincere eyes and felt warm and guilty in his heart. He knew his daughter loved him deeply. He finally made up his mind to break this bad habit for his family. 注意： （1）续写词数应为150左右； （2）请按如下格式在答题纸相应位置作答。 However, in the first few days, Jason couldn’t help smoking secretly. ________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ Two months later, Jason managed to stay away from cigarettes. ________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ 【答案】例文 However, in the first few days, Jason couldn’t help smoking secretly. The urge to smoke struck him constantly, especially after meals and when he felt tired. He even took out a cigarette and lit it secretly in the bedroom. But the moment he saw Helen’s notebook lying on the table, guilt flooded his heart. He put out the cigarette immediately and decided to stick to his promise. Helen noticed his struggle but never blamed him. Instead, she cheered him up and shared interesting stories with him to distract his attention. Two months later, Jason managed to stay away from cigarettes. He finally got rid of the bad habit and no longer suffered from bad coughs. The unpleasant smell at home disappeared completely, and the whole family felt much healthier. To celebrate his success, Helen gave him a delicate gift as promised. Jason hugged Helen tightly, saying it was the most precious gift he had ever received. He realized that nothing was more important than the health and happiness of his family. 【导语】本文讲述了海伦的父亲杰森长期吸烟。担心父亲健康与二手烟危害，海伦温和劝说他戒烟，准备笔记本记录并许诺礼物。起初杰森忍不住偷偷抽烟，但在海伦鼓励下坚持下来。两个月后他成功戒烟，全家收获更健康的生活。 【详解】1.段落续写： ①由第一段首句内容可知，第一段可描写起初杰森忍不住偷偷抽烟，但在海伦鼓励下坚持下来。 ②由第二段首句内容可知，第二段可描写两个月后他成功戒烟，全家收获更健康的生活。 2.续写线索：忍不住偷偷抽烟→海伦鼓励→转移注意力→戒烟成功→收获健康生活 3.词汇激活 行为类 ①意识到：realize/be aware of ②使高兴：cheer up/lighten up 情绪类 ①疲惫的：tired/worn/exhausted ②令人不愉快的：unpleasant/disagreeable 【点睛】[高分句型1] The urge to smoke struck him constantly, especially after meals and when he felt tired.（运用了when引导时间状语从句） [高分句型2] He realized that nothing was more important than the health and happiness of his family.（运用了that引导宾语从句） 2 / 2 2 / 2 学科网（北京）股份有限公司 $听力考试正式开始。Does this place keep animals to entertain people?

On March 23, people first saw it trapped on a sandbank near the city of Luebeck. It managed to free itself but then became stuck again several times. Finally, on a Saturday morning, after weeks of effort, the whale was released into the North Sea off the coast of Denmark. It had been carried on a large flat boat called a barge. A member of the rescue team said the whale left the barge at around 8:45 am and was now swimming on its own, freely, and in the right direction. The rescue team members cheered as they watched Timmy disappear into the deep water. However, the rescue effort was anything but easy. The whale’s long struggle attracted a lot of media attention. TV channels, websites, and social media influencers covered the story non-stop. At the beginning of April, German officials had given up trying to save the whale. They believed the animal was too weak and could not survive. However, many people were very upset about this decision. They wrote letters, called officials, and expressed their anger on social media. Two wealthy businessmen then proposed a private rescue plan. After strong public pressure, the government finally agreed to let them try. The rescuers first tried using inflatable cushions and floating platforms, but that did not work. The whale was too large and the water too shallow. Then they came up with the idea of using a barge to transport the whale to deeper water. Many experts criticized the plan, saying it would only cause the whale more pain and stress. The rescue effort was seen as unlikely to succeed. But the rescue team decided to go ahead anyway. Fortunately, the rescue was a success. Timmy was set free and swam away. 24．(2.5分)What happened to the whale at first? A．It was hit by a large boat. B．It was caught off the coast. C．It was saved by German officials. D．It was released into the North Sea. 25．(2.5分)How did the public feel about the whale? A．Concerned. B．Uncaring. C．Disappointed. D．Hopeful. 26．(2.5分)What can we learn from the last two paragraphs? A．Media attention postponed the rescue. B．The whale got hurt during the rescue. C．The rescue process was not smooth. D．The rescue was funded by the public. 27．(2.5分)What is the best title for the passage? A．Practical Ways to Save a Whale B．Timmy the Whale: A Cry for Help C．The Secret Life of a Humpback Whale D．Timmy the Whale: An Eventful Rescue （本题10分）Local volunteer groups have become an important driving force for ecological protection on the Qinghai-Tibet Plateau (高原). Many people have the wrong idea that wildlife protection only means saving one rare animal. In fact, real ecosystem protection refers to protecting whole food chains and natural habitats. A healthy ecosystem means a balance among plants, animals, and tiny living things that break down waste. Losing even one small part can cause big problems. Volunteers in high areas do many practical field tasks. They walk into rivers to pick up floating rubbish, often filling many bags each time. They keep records of wild animal movements, writing down the types, numbers, and places. They also remove harmful plants that grow too fast and hurt local plants. Most of these volunteers are local people. They know the land well and understand seasonal changes, so they are good at outdoor work. Before they start, they receive training from environmental researchers. They learn how to recognize different animals and plants and how to use simple tools. Working on the plateau is physically hard. The air is thin above 4,000 meters, so even walking feels tiring. Strong sunlight can hurt skin quickly. Cold winds blow often, especially in winter. But their work does not try to make fast changes. Instead, they focus on long-term watching and slow improvement. Some projects may take years to show clear results. Local people combine their old knowledge with modern protection methods. For example, they use traditional ways of raising farm animals to avoid disturbing wildlife when they have babies. Experts say that community-led volunteer work is a useful addition to government protection programs. Government teams often work in large nature reserves, while local volunteers help in smaller, faraway places. When locals and researchers work together, they get better results for the plateau’s fragile environment. 28．(2.5分)How does the author explain “a healthy ecosystem” in Paragraph 1? A．By giving a typical example. B．By giving a clear definition. C．By telling a detailed story. D．By comparing diverse ideas. 29．(2.5分)What makes local people good at field work? A．They have modern tools. B．They work for the government. C．They receive a high pay. D．They know the land and seasons. 30．(2.5分)What does Paragraph 3 mainly talk about? A．The training volunteers receive. B．The beauty of the plateau land. C．The challenges volunteers face. D．The fast results of their work. 31．(2.5分)What’s the best structure of the passage? A．Clarification → Actions → Difficulties → Significance B．Concept → Examples → Comparison → Prediction C．Background → Story → Analysis → Suggestion D．Problem → Practices → Examples → Solution （本题10分）A new study sheds light on how methane (甲烷) is produced in the open ocean. Researchers at the University of Rochester identified the process could grow stronger as global temperatures rise. Methane is a powerful greenhouse gas, yet scientists have long been puzzled by an unusual pattern. Surface ocean waters regularly release methane into the atmosphere, even though these waters contain plenty of oxygen. Traditionally, methane formation has been linked to environments without oxygen, such as wetlands or deep ocean sediments. To better understand this contradiction, the research team combined global data with computer simulations. They found that certain microbes (微生物) can produce methane as they break down organic material, but only when phosphate, a key nutrient, is in short supply. This discovery changes how scientists view methane production in marine environments. The study also highlights how climate change could influence this process in the future. As the ocean warms, the difference in density between surface water and deeper layers increases. This is expected to slow the upward and downward mixing that carries nutrients like phosphate up from depth. With less mixing, fewer nutrients reach the surface. The team’s model shows that this could leave surface waters increasingly depleted of phosphate, creating favorable conditions for methane-producing microbes. If methane production rises, more of this gas could escape into the atmosphere. Because methane is so effective at trapping heat, this creates the risk of an intensifying cycle: Warmer oceans lead to higher methane emission, which then contributes to further warming. Importantly, this cycle mechanism is not yet included in most major climate models. As scientists work to improve predictions, accounting for processes like this may be crucial for understanding how quickly climate change will progress. “Our work will help fill a key gap in climate prediction, which often ignores interactions between the changing environment and natural greenhouse gas sources to the atmosphere,” says Thomas Weber, one member of the research team. 32．(2.5分)What puzzled scientists about methane in the open ocean? A．It is produced in deep ocean. B．It is fading in trapping heat. C．It arises in oxygen-rich water. D．It speeds up ocean warming. 33．(2.5分)What does the underlined word “depleted” in paragraph 4 mean? A．Warned. B．Composed. C．Accused. D．Starved. 34．(2.5分)What can be inferred about the cycle mentioned in paragraph 5? A．It relies on sufficient phosphate. B．It could speed up global warming. C．It is included in most climate models. D．It weakens methane’s warming effect. 35．(2.5分)What does Thomas Weber think of their discovery? A．It applies to specific ocean regions. B．It’s a missing link in climate models. C．It’s a result based on ideal conditions. D．It works in controlling climate change. （本题12.5分）Finding Nemo just got trickier. Why? Because it looks like clownfish are shrinking. The colourful fish, made famous by the popular animated film, can quickly reduce their size as a way to deal with heat stress, a study in Science Advances suggests. 36(2.5分) Researchers studied 67 pairs of clownfish living in reefs off Kimbe Bay in Papua New Guinea during the marine heatwave of 2023. 37(2.5分) Adult clownfish grow to be about 8cm long but these animals lost a couple of millimetres in the space of a few months. “This is not just about getting skinnier under stressful conditions, these fish are actually getting shorter,” says Melissa Versteeg. It’s well known that animals can evolve to become smaller over generations. 38(2.5分) For example, some fish on remote islands gradually shrink in size. But these are evolutionary changes that occur across hundreds of years. It may not sound it but this rapid response is actually good for the fish. Shrinking increased individuals’ chances of surviving the heatwave by as much as 78 per cent, the team found. 39(2.5分) We don’t yet know if other fish species are also shrinking during heatwaves but, if they are, it could explain a bigger trend: many ocean fish are getting smaller. Other explanations include pollution, habitat degradation, overfishing and food web disruptions. 40(2.5分) A．They measured the fish every month for five months and found 75% shrank. B．The study also solves the problem of worldwide overfishing in the oceans. C．This finding may explain why fish worldwide are becoming smaller in warmer seas. D．Island dwarfism is a typical case caused by limited resources on islands. E．Marine heatwaves are becoming more frequent as global temperatures rise. F．Many cartoon characters are based on lovely sea animals like clownfish. G．So this rapid shrinking could be a key new explanation for smaller fish. 三、完形填空 （本题15分）It was an October afternoon on the coast when the Marine Mammal Center got a call on its public hotline. There were 41 cries coming from the freezing waters in Morro Bay. The center’s experts were able to 42 that the calls — which sounded almost like a human baby screaming — were coming from a(n) 43 2-week-old sea otter (獭) pup (幼崽) that had been separated from its mother. That could be 44 for the young sea otter and it could die, according to Shayla Zink, who works at the center. “That pup is really 45 everything it learns from the mother to be able to survive in the ocean,” Zink said. The employees at the center jumped into action without 46 . First, they put the baby otter, whom they named “Caterpillar,” into a safe container where it wouldn’t overheat. Then, they recorded the 47 of the pup’s frightened cries. The plan was to 48 the mother towards the boat by broadcasting the pup’s cries through a Bluetooth speaker. Eventually, a female otter 49 the boat. Once Zink felt certain that the otter was looking for her baby, she 50 the pup into the water. Instantly, the mom 51 her baby in her arms and appeared to smell him, 52 her small hands over his fur. The 53 has bigger significance to the region, where sea otters play a crucial role in 54 biodiversity. “It’s just a really special 55 to see them gather together, because every individual in this population is of great importance in keeping it going and bringing it back from that threatened status,” Zink said. 41．(1分)A．awful B．painful C．doubtful D．cheerful 42．(1分)A．guess B．recall C．imagine D．determine 43．(1分)A．annoyed B．excited C．scared D．confused 44．(1分)A．unique B．common C．dangerous D．comfortable 45．(1分)A．relying on B．handing out C．contributing to D．springing into 46．(1分)A．delay B．doubt C．exception D．permission 47．(1分)A．action B．sound C．behaviour D．expression 48．(1分)A．cheat B．protect C．attract D．comfort 49．(1分)A．left B．avoided C．controlled D．followed 50．(1分)A．brought B．lowered C．replaced D．attacked 51．(1分)A．threw B．grabbed C．affected D．ignored 52．(1分)A．running B．placing C．pushing D．drawing 53．(1分)A．condition B．ambition C．reunion D．decision 54．(1分)A．destroying B．restricting C．identifying D．preserving 55．(1分)A．duty B．lesson C．example D．moment 四、语法填空 （本题15分）阅读下面短文，在空白处填入1个适当的单词或括号内单词的正确形式。 Human activities cause increasing harm to animals. When you think of a fearsome hunter, images of lions and sharks may spring 56(1.5分) mind. Recent research by 57(1.5分) (environment) scientists, however, shows that in fact, humans are the most fearsome hunters 58(1.5分) have the greatest impact on animal populations. In the last 500 years, over 300 species of animals 59(1.5分) (go) extinct. Some activities, such as hunting and fishing, 60(1.5分) (direct) harm animals, while other activities, such as development in towns and cities, impact indirectly on animal populations. Hunting and fishing have influenced the world’s animal populations. Some people hunt animals for food: whale meat 61(1.5分) (eat) in some parts of the world. Some people hunt animals for fashion: animal skin is used to make coats and bags. Still others hunt animals just for fun: deer are tracked 62(1.5分) shot by people who enjoy the excitement of the sport. Human activities that have indirect effects on animals can be just as harmful. When we build farms or factories, we destroy animal habitats and leave many animals with nowhere 63(1.5分) (live), or no food to eat. We can also put animals in danger without ever entering their habitats. Air, water, noise and light pollution can all have a deep and 64(1.5分) (damage) influence quite far from their source. Partly due to pollution 65(1.5分) (cause) by ship traffic and other human activities, the dolphin population has dropped greatly. As the human population continues to grow, so does the effect we have on animals. 五、书信写作 66．（本题15分）当今，绿色生活已日益成为人们的共识。你校英文报正在开展以“Green Life at Home”为题的征文活动。请你用英语写一篇短文投稿，内容包括： 1、绿色生活的重要性； 2、你的做法； 3、你的倡议。 注意：(1)写作词数应为 80 个左右。 (2)请按如下格式在答题卡的相应位置作答。 Green Life at Home ________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ Green Life at Home     Green living is essential for saving resources and reducing pollution.

He smoked after meals, while working, and even when he rested at home. Every time he lit a cigarette, thin white smoke filled the room, leaving a strong, unpleasant smell on his clothes and hair. Helen had long disliked her father’s smoking habit. She learned from her teacher that smoking was really harmful to people’s health. It could hurt the lungs, cause bad coughs and even lead to serious illnesses. What worried Helen most was that her father often coughed badly at night. Besides, second-hand smoke was also bad for the whole family’s health. She had tried to ask her father to give up smoking many times, but Jason always shook his head and said it was too hard for him to stop. One Sunday afternoon, Helen saw her father smoking again in the yard. He looked tired after a whole week’s work. Helen walked over quietly and did not blame (责怪) him at once. Instead, she sat beside him and talked with him gently. She told her father how worried she was about his health. She said she hoped her father could accompany (陪伴) her to grow up. To encourage her father, Helen prepared a small notebook. She planned to record every day when her father did not smoke. She also promised to give him a small gift if he could keep not smoking for a month. Jason looked at his daughter’s sincere eyes and felt warm and guilty in his heart. He knew his daughter loved him deeply. He finally made up his mind to break this bad habit for his family. 注意： （1）续写词数应为150左右； （2）请按如下格式在答题纸相应位置作答。 However, in the first few days, Jason couldn’t help smoking secretly. ________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ Two months later, Jason managed to stay away from cigarettes. ________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ 2 / 2 2 / 2 学科网（北京）股份有限公司 $
