On February 22, 2026, a seabird was trapped in the mud because a balloon string had wrapped around its body and wings. As soon as he received the 1 about the seabird, Huang rushed to the site. At first, Huang tried to rescue the bird with 2 , but strong winds forced him to 3 . Then he decided to use a rope which was about 100 metres ahead of him. He 4 a rope around his waist and started his rescue. After a few 5 , Huang realized he had no choice but to move closer to the bird and freed it from the string. However, on his way back, he found himself stuck in the mud. With the help of the others, Huang 6 made his way back across the mud. The seabird was later taken to an animal rescue station. It wasn’t injured, but it was so 7 that it was unable to fly. After it made a full 8 , the seabird was sent back into the wild. Since he 9 the wildlife protection society, Huang has volunteered for about ten years. He often takes part in animal rescue operations. Speaking about the rescue, he said, “It’s our duty. For us, every rescue is 10 .

According to a study in Nature Climate (气候) Change, the number of most polar bears will 1 rapidly by 2080. There are two reasons. One is that the sea ice is melting (融化). Polar bears catch seals (海豹) to eat on the ice. 2 ice, they have to stay on land. But there is not 3 food on land to feed so many bears. The animals could die from hunger. The other reason is that mother bears may not be fat enough to 4 milk to their babies, so some bears could stop having babies. Polar bears are 5 land animals that eat meat on the planet. They help control other kinds of animals. Losing them would break the balance (平衡) of their living place. The Arctic (北极) is the 6 to about 25,000 polar bears. Arctic sea ice usually melts in spring and summer, then grows in winter. But now, the 7 is taking longer to grow back. Scientists say the Arctic is warming twice as fast as the rest of the planets. The study also shows 8 it is possible to slow Arctic melting. Greenhouse gases (温室气体) could lead to climate change. In order to avoid (避免) creating greenhouse gases, the world should try to stop burning coal and riding in cars. Saving the bears is 9 us. Holland, one of the writers of the study, says, “I believe there is hope, but humans need to act 10 to make that hope come true.” Let’s take action to protect our earth and save polar bears. 1．A．develop B．fall C．rise D．improve 2．A．Through B．Across C．Without D．Onto 3．A．enough B．good C．sweet D．delicious 4．A．protect B．drop C．invent D．offer 5．A．the largest B．the loveliest C．the simplest D．the luckiest 6．A．room B．family C．house D．home 7．A．sea B．ice C．plant D．animal 8．A．if B．when C．that D．whether 9．A．up to B．hard on C．good with D．thankful to 10．A．widely B．clearly C．quickly D．quietly The wolf plays a very important role in keeping the health of an ecosystem. In Yellowstone National Park in the United States, a famous 1 helped to prove this. Wolves had been absent from the park for almost 70 years. During this time, the number of deer grew and grew. They ate so much grass that many plants and trees 2 . Without trees, birds could not find places to build their nests. The animals that depended on these plants for food also became fewer. In 1995, scientists decided to 3 wolves back to the park. At first, people were worried that the wolves would be a great danger to the deer and even to people. However, the return of the wolves 4 the ecosystem in many wonderful ways. First, the wolves hunted some of the deer, so the deer population was controlled. Then, with fewer deer, the trees and plants began to grow again. This allowed birds and other animals to 5 . Even the rivers changed! The growing tree roots made the river banks 6 , so the rivers became cleaner and straighter. The story of Yellowstone tells us that every 7 , even the one we sometimes fear, has its place in nature. The 8 of just one kind of animal can affect the whole ecosystem. We should try our best to 9 the balance of nature.

So it’s very important to keep 1 balanced. In recent years, more and more people have realized the 2 of ecological balance. We are now 3 to keep nature in balance. First, there are strict rules to 4 pollution. Factories must clean their waste before it goes into the air or water. Second, the government has built nature parks to protect animals and plants. In these areas, people cannot hunt, and many trees are 5 to grow new forests. These steps help wildlife live 6 . Tourists can help too! They are asked to travel in a green way. In beautiful places, signs tell tourists not to throw 7 or scare animals. Some parks only allow a certain number of 8 to visit each day. This helps protect nature. Because of these actions, our 9 is getting better. The air is fresher, the water is 10 , and some endangered animals are coming back. All of this tells us: When everyone helps, we can protect the Earth.

Some scientists say that there will not be any great forests 4 20 or 30 years. What will happen if the forests disappear? A lot of plants will die and the animals will 5 their homes. In many places the new farmland will soon look 6 the old desert. Crops will not grow there. There won’t be enough 7 , and the weather will get hot and dry. If the climate of the earth changes, life will be 8 for everyone. Our living environment will become 9 . More and more rich farmland will disappear.

Encouraged by Minqin’s long history of battling the desert, Zhong thinks it is now the young people’s responsibility to 2 the job, even as many of his classmates crowd into big cities. Of course, the 3 came with challenges. Zhong was short of money. He also faced 4 from family and friends who once saw his act as “foolish”. The work itself is 5 , too. Take the sandstorm this March as an example, only after covering his mouth and nose tightly could he keep 6 to plant saplings (树苗). Sometimes he works in the sun all day, getting sunburnt. However, seeing the desert turn green makes all the tiredness 7 . “Every tree we plant is a 8 against the sand,” Zhong said. He also tries to bring more young people back.

That 1 changed when my school started an Eco-Club last term. At first, I was 2 to join because I thought it would be boring and take up too much study time. But my best friend Lily, who was already a member, 3 me to give it a try. Our first activity was a beach clean-up at the nearby Yangtze River bank. When we arrived, I was 4 to see so much plastic waste scattered everywhere. We spent three hours picking up bottles, bags and food wrappers. By the end, my back ached and my hands were dirty, 5 when I looked at the clean beach we had created, I felt a strong sense of 6 . After that, I became more active in the club. We organized a “No Single-Use Plastics” campaign at school, 7 students to bring reusable water bottles and lunch boxes. We also set up a recycling corner in each classroom and taught everyone how to 8 waste properly. Last month, we worked with the local community to plant 50 trees in the neighborhood park. I helped dig holes and carry saplings. Watching the small trees standing straight in the ground, I realized that every small 9 matters. Environmental protection is not about doing big things alone; it’s about making small changes in our 10 lives. Now, the Eco-Club has grown to over 100 members. We meet every Friday afternoon to plan new activities. I have learned so much about the environment and have made many new friends. Most importantly, I have 11 a sense of responsibility for protecting our planet. I used to be the one who would 12 away from environmental issues, but now I am proud to be an eco-volunteer. I tell my family and friends about the importance of going green and encourage them to join me. 13 everyone makes a small effort, we can make a big difference to our world. The Earth is our only home, and it’s our duty to take care of it. I will continue to do my part to protect the environment, and I hope more people will 14 us.

Holland, one of the writers of the study, says, “I believe there is hope, but humans need to act 10 to make that hope come true.” Let’s take action to protect our earth and save polar bears. 1．A．develop B．fall C．rise D．improve 2．A．Through B．Across C．Without D．Onto 3．A．enough B．good C．sweet D．delicious 4．A．protect B．drop C．invent D．offer 5．A．the largest B．the loveliest C．the simplest D．the luckiest 6．A．room B．family C．house D．home 7．A．sea B．ice C．plant D．animal 8．A．if B．when C．that D．whether 9．A．up to B．hard on C．good with D．thankful to 10．A．widely B．clearly C．quickly D．quietly 【答案】 1．B 2．C 3．A 4．D 5．A 6．D 7．B 8．C 9．A 10．C 【导语】本文介绍了由于全球变暖，北极熊可能在本世纪末大量消失的现状，分析了其原因，强调了保护北极熊对生态平衡的重要性，并提出减缓北极融化的方法，呼吁人类迅速行动起来保护地球和北极熊。 1．句意：根据《自然气候变化》的一项研究，到2080年，大多数北极熊的数量将迅速下降。 develop发展；fall下降；rise上升；improve改善。根据“Most polar bears could disappear by the end of the century”可知，北极熊数量会“下降”。故选B。 2．句意：没有冰，它们就不得不待在陆地上。 Through穿过；Across横过；Without没有；Onto到……上。根据“the sea ice is melting”及“stay on land”可知，“没有”冰时北极熊只能上岸。故选C。 3．句意：但陆地上没有足够的食物喂养这么多熊。 enough足够的；good好的；sweet甜的；delicious美味的。根据“die from hunger”可知，食物“不足”。故选A。 4．句意：另一个原因是母熊可能不够胖，无法给幼崽提供奶水，所以有些熊可能会停止生育。 protect保护；drop掉落；invent发明；offer提供。根据“milk to their babies”可知，母熊需要“提供”奶水。故选D。 5．句意：北极熊是地球上最大的陆生食肉动物。 the largest最大的；the loveliest最可爱的；the simplest最简单的；the luckiest最幸运的。根据常识及“land animals that eat meat”可知，北极熊是“最大的”陆生食肉动物之一。故选A。 6．句意：北极是约25,000只北极熊的家园。 room空间；family家庭；house房子；home家园。根据“to about 25,000 polar bears”可知，北极是北极熊的“家园”，固定搭配“be home to”表示“是……的栖息地”。故选D。 7．句意：但现在，冰需要更长时间才能重新形成。 sea海洋；ice冰；plant植物；animal动物。根据“Arctic sea ice usually melts...then grows in winter”可知，此处指“冰”的重新形成，ice与前文呼应。故选B。 8．句意：研究还表明，减缓北极融化是可能的。 if如果；when当……时；that引导宾语从句，无实义；whether是否。根据“the study also shows...it is possible...”可知，宾语从句成分完整，用that引导（无实义）。故选C。 9．句意：拯救北极熊取决于我们。 up to取决于；hard on对……苛刻；good with善于应付；thankful to感谢。根据“humans need to act”可知，拯救北极熊“取决于”人类。故选A。 10．句意：“我相信有希望，但人类需要迅速行动，才能让希望成真。” widely广泛地；clearly清晰地；quickly迅速地；quietly安静地。根据“make that hope come true”及北极熊濒危的现状可知，人类需要“迅速”行动，quickly 符合语境。故选C。 The wolf plays a very important role in keeping the health of an ecosystem. In Yellowstone National Park in the United States, a famous 1 helped to prove this. Wolves had been absent from the park for almost 70 years. During this time, the number of deer grew and grew. They ate so much grass that many plants and trees 2 . Without trees, birds could not find places to build their nests. The animals that depended on these plants for food also became fewer. In 1995, scientists decided to 3 wolves back to the park. At first, people were worried that the wolves would be a great danger to the deer and even to people. However, the return of the wolves 4 the ecosystem in many wonderful ways. First, the wolves hunted some of the deer, so the deer population was controlled. Then, with fewer deer, the trees and plants began to grow again. This allowed birds and other animals to 5 . Even the rivers changed! The growing tree roots made the river banks 6 , so the rivers became cleaner and straighter. The story of Yellowstone tells us that every 7 , even the one we sometimes fear, has its place in nature. The 8 of just one kind of animal can affect the whole ecosystem. We should try our best to 9 the balance of nature. Sometimes, 10 nature take its course is the best choice. 1．A．film B．experiment C．book D．movie 2．A．grew B．appeared C．died D．disappeared 3．A．bring B．take C．push D．carry 4．A．protected B．polluted C．improved D．discovered 5．A．disappear B．return C．hide D．move 6．A．weaker B．softer C．stronger D．wider 7．A．human B．plant C．animal D．bird 8．A．food B．home C．number D．beauty 9．A．test B．break C．keep D．find 10．A．helping B．letting C．making D．asking 【答案】 1．B 2．D 3．A 4．C 5．B 6．C 7．C 8．C 9．C 10．B 【导语】本文是一篇说明文。文章通过黄石公园重新引入狼群的案例，说明了狼在维持生态系统健康方面的重要作用，呼吁保护自然平衡。 1．句意：在美国黄石国家公园，一个著名的实验帮助证明了这一点。 根据下文科学家重新引入狼群并观察生态变化的过程可知，这是一个科学“实验”，experiment“实验”符合语境。film“电影”、book“书籍”、movie“影片”均不符合文意。 2．句意：它们吃掉大量青草，许多植物和树木消亡了。 根据“They ate so much grass”可知，过度啃食导致植物消失，disappeared“消失”符合语境。grew“生长”、appeared“出现”意思相反；died多指生命体死去，用来形容树木此处不如disappeared贴合整体环境衰败。 3．句意：1995年，科学家决定把狼带回公园。 根据“back to the park”及语境可知，是把狼“带”回去，bring back为固定搭配，意为“带回”；bring“带”符合短语搭配。take“拿走”、push“推”、carry“搬运”不能和back构成这个搭配。 4．句意：然而，狼的回归在许多奇妙的方面改善了生态系统。 However表示转折，前文提到人们担心危险，后文描述积极变化，故狼群“改善”了生态，improved“改善”契合语境。protected“保护”，polluted“污染”，discovered“发现”不符合句意。 5．句意：这使得鸟类和其他动物得以返回。 根据前文“Without trees, birds could not find places…”可知，树木恢复后，动物们可以“返回”，return“返回”符合语境。disappear“消失”语义相反；hide“躲藏”，move“搬迁”不符合。 6．句意：生长的树根让河岸更加坚固，河水变得更清澈、河道更加笔直。 根据“so the rivers became cleaner and straighter”可知，树根固土使河岸“更坚固”，防止侵蚀，stronger“更坚固的”符合常识。weaker“更虚弱的”，softer“更柔软的”，wider“更宽阔的”均错误。 7．句意：黄石公园的故事告诉我们，每种动物，即使是我们有时害怕的那种，在自然界都有其位置。 本文主要讲述狼（动物）的作用，此处泛指每种“动物”，animal“动物”贴合主旨。human“人类”、plant“植物”、bird“鸟类”概括片面。 8．句意：仅仅一种动物的数量就能影响整个生态系统。 根据前文狼群消失和回归导致生态变化可知，动物的“数量”变化影响生态，number“数量”符合语境。food“食物”，home“家园”，beauty“美丽”不符合语境。 9．句意：我们应该尽最大努力保持自然平衡。 keep the balance of nature是固定搭配，意为“维持生态平衡”，keep“保持”。test“测试”，break“打破”，find“找到”搭配不当。 10．句意：有时，让自然顺其自然是最好的选择。 let nature take its course为固定短语，表示顺其自然，letting“让”。helping“帮助”，making“制作”，asking“询问”不适用该固定搭配。 We depend on each other in the ecosystem of the Earth. So it’s very important to keep 1 balanced. In recent years, more and more people have realized the 2 of ecological balance. We are now 3 to keep nature in balance. First, there are strict rules to 4 pollution. Factories must clean their waste before it goes into the air or water. Second, the government has built nature parks to protect animals and plants. In these areas, people cannot hunt, and many trees are 5 to grow new forests. These steps help wildlife live 6 . Tourists can help too! They are asked to travel in a green way. In beautiful places, signs tell tourists not to throw 7 or scare animals. Some parks only allow a certain number of 8 to visit each day. This helps protect nature. Because of these actions, our 9 is getting better. The air is fresher, the water is 10 , and some endangered animals are coming back. All of this tells us: When everyone helps, we can protect the Earth. Let’s keep working together for a green and healthy world! 1．A．subjects B．ecosystems C．sports D．researches 2．A．youth B．blood C．importance D．culture 3．A．taking action B．mixing up C．coming alive D．making sense 4．A．produce B．control C．inspire D．grow 5．A．sold B．rated C．broken D．planted 6．A．safely B．suddenly C．actually D．differently 7．A．information B．pleasure C．rubbish D．treasure 8．A．doctors B．scientists C．volunteers D．tourists 9．A．decision B．imagination C．luck D．environment 10．A．warmer B．colder C．cleaner D．hotter 【答案】 1．B 2．C 3．A 4．B 5．D 6．A 7．C 8．D 9．D 10．C 【导语】本文主要讲述了保护地球生态平衡的重要性，详细介绍了政府及游客为保护环境所采取的具体措施及最终取得的显著成效。 1．句意：因此，保持生态系统的平衡是非常重要的。 前一句提到“We depend on each other in the ecosystem of the Earth.”，所以这里自然是指保持“生态系统”的平衡。ecosystems“生态系统”符合语境；subjects“科目”、sports“运动”、researches“研究”均与前文铺垫的生态话题无关。 2．句意：近年来，越来越多的人意识到了生态平衡的重要性。 第一段明确指出“it’s very important to keep... balanced”，因此人们意识到的是其“重要性”。importance“重要性”符合语境；youth“青春”、blood“血液”、culture“文化”均不符合文意。 3．句意：我们现在正采取行动来保持自然的平衡。 后文分别列举了“First, there are strict rules... Second, the government has built... Tourists can help too!”等一系列具体的举措，这说明人们正在将保护环境付诸“行动”。taking action“采取行动”符合语境与固定搭配；mixing up“混淆”、coming alive“活跃起来”、making sense“有意义”均不符合开展环保举措的逻辑。 4．句意：首先，有严格的规定来控制污染。 后句解释了工厂必须在排放废弃物前进行清理（clean their waste before it goes into the air or water），清理废弃物的目的正是为了“控制”污染。control“控制”符合语境；produce“生产/产生（污染）”与环保目的完全相反，inspire“启发”、grow“种植”不能与污染搭配。 5．句意：在这些地区，人们不能打猎，并且种了许多树来培育新森林。 结合常识和原文后文“to grow new forests”，森林是由树木“种植”而成的。此处使用被动语态，planted“种植”符合语境；sold“卖”、rated“评级”、broken“打破”均不符合培育森林的具体动作。 6．句意：这些措施帮助野生动物安全地生活。 前文提到政府建立了自然公园，并且“people cannot hunt”，这样野生动物免受了猎杀威胁，自然能“安全地”生活。safely“安全地”符合语境逻辑；suddenly“突然地”、actually“实际上”、differently“不同地”均无法体现禁猎保护措施带来的正面效果。 7．句意：在风景优美的地方，指示牌告诉游客不要乱扔垃圾或惊吓动物。 前句提到游客被要求以绿色环保的方式出行（travel in a green way），在景区内典型的破坏环境且需要被禁止的行为就是扔“垃圾”。rubbish“垃圾”符合语境；information“信息”、pleasure“快乐”、treasure“财宝”均不符合“不要乱扔（not to throw）”的逻辑。 8．句意：一些公园每天只允许一定数量的游客参观。 这段话开头就点明了主语群体：“Tourists can help too!”，且空格所在句说的是参观（visit），所以为了保护环境而限制数量的自然是“游客”。tourists“游客”符合语境；doctors“医生”、scientists“科学家”、volunteers“志愿者”均不是此处讨论的特定群体。 9．句意：因为这些行动，我们的环境正在变得更好。 后文紧接着描述了具体的改善表现：“The air is fresher, the water is... and some endangered animals are coming back.”，这些条件和生态的变化统称为“环境”的改善。environment“环境”符合语境；decision“决定”、imagination“想象力”、luck“运气”均无法概括这些自然界的变化。 10．句意：空气更清新了，水更清澈了，一些濒危动物也回来了。 此处运用了排比和并列结构描写环境变好，与“The air is fresher”相对应，水质变好的自然表现是变得“更干净/清澈”。cleaner“更干净的”符合语境；warmer“更暖和的”、colder“更冷的”、hotter“更热的”通常不作为水环境变好的评价标准。 阅读下面短文，从每题所给的A、B、C、D四个选项中选出最佳选项。 Today we can see that many people are cutting down the trees in the forests. A lot of 1 lands have become deserts. If we read newspapers, we’ll learn that the forests on the earth are getting smaller 2 . We are cutting down large numbers of trees 3 we need wood and farmland.

In 2021, Zhong returned to his hometown to start a 1 business, becoming a key person in efforts to stop desertification (沙漠化). Encouraged by Minqin’s long history of battling the desert, Zhong thinks it is now the young people’s responsibility to 2 the job, even as many of his classmates crowd into big cities. Of course, the 3 came with challenges. Zhong was short of money. He also faced 4 from family and friends who once saw his act as “foolish”. The work itself is 5 , too. Take the sandstorm this March as an example, only after covering his mouth and nose tightly could he keep 6 to plant saplings (树苗). Sometimes he works in the sun all day, getting sunburnt. However, seeing the desert turn green makes all the tiredness 7 . “Every tree we plant is a 8 against the sand,” Zhong said. He also tries to bring more young people back.

In 2021, Zhong left city life in Lanzhou and returned home to fight desert growth. His hometown has fought against desertification (沙漠化) for hundreds of years. Now, young people like him are 2 . Zhong faced 3 times—little money and doubt from his family and friends. After a sandstorm, most of the new trees 4 . But he kept going. He shared his work online. In 2024, he joined a TV show about farming. 5 , more young people came to help. He built simple homes for volunteers—now called the “Desert Home Base”. “Thinking only gives me 6 , but doing brings answers,” he said. Li Yanyan, 20, studies nature protection at Beijing Forestry University. She found that glass buildings on campus were killing birds. She joined a national project, collected data, and asked the school to act. By December 2024, nearly 300 square metres of glass had been made 7 for birds. Her work spread to other schools. Sheng Tiancheng, a finance student, loves wildlife. He began bird-watching at 12 and now uses his 8 to help animals. His photos won a national prize.

That 1 changed when my school started an Eco-Club last term. At first, I was 2 to join because I thought it would be boring and take up too much study time. But my best friend Lily, who was already a member, 3 me to give it a try. Our first activity was a beach clean-up at the nearby Yangtze River bank. When we arrived, I was 4 to see so much plastic waste scattered everywhere. We spent three hours picking up bottles, bags and food wrappers. By the end, my back ached and my hands were dirty, 5 when I looked at the clean beach we had created, I felt a strong sense of 6 . After that, I became more active in the club. We organized a “No Single-Use Plastics” campaign at school, 7 students to bring reusable water bottles and lunch boxes. We also set up a recycling corner in each classroom and taught everyone how to 8 waste properly. Last month, we worked with the local community to plant 50 trees in the neighborhood park. I helped dig holes and carry saplings. Watching the small trees standing straight in the ground, I realized that every small 9 matters. Environmental protection is not about doing big things alone; it’s about making small changes in our 10 lives. Now, the Eco-Club has grown to over 100 members. We meet every Friday afternoon to plan new activities. I have learned so much about the environment and have made many new friends. Most importantly, I have 11 a sense of responsibility for protecting our planet. I used to be the one who would 12 away from environmental issues, but now I am proud to be an eco-volunteer. I tell my family and friends about the importance of going green and encourage them to join me. 13 everyone makes a small effort, we can make a big difference to our world. The Earth is our only home, and it’s our duty to take care of it. I will continue to do my part to protect the environment, and I hope more people will 14 us. Together, we can build a greener and more beautiful future for 15 . 1．A．opinion B．habit C．dream D．plan 2．A．excited B．willing C．hesitant D．confident 3．A．forced B．persuaded C．allowed D．ordered 4．A．happy B．angry C．shocked D．moved 5．A．so B．but C．or D．because 6．A．pride B．guilt C．sadness D．regret 7．A．forcing B．allowing C．encouraging D．warning 8．A．throw B．sort C．burn D．bury 9．A．mistake B．change C．effort D．decision 10．A．daily B．busy C．hard D．happy 11．A．lost B．developed C．forgotten D．shared 12．A．run B．look C．turn D．walk 13．A．If B．Unless C．Although D．Because 14．A．help B．join C．support D．follow 15．A．themselves B．yourselves C．ourselves D．itself 【答案】 1．A 2．C 3．B 4．C 5．B 6．A 7．C 8．B 9．C 10．A 11．B 12．A 13．A 14．B 15．C 【导语】本文讲述了作者加入学校生态俱乐部后，通过参与环保活动改变了对环境保护的看法，并培养了责任感的故事。 1．句意：当我的学校上学期开始了一个生态俱乐部时，那个观点改变了。 根据前文“I used to think environmental protection was something only adults...”可知，作者之前的想法是一种“观点”，故选opinion。 2．句意：起初，我犹豫是否加入，因为我认为它会很无聊且占用太多学习时间。 根据“because I thought it would be boring”可知，作者内心是不情愿的，因此是“犹豫”的，故选hesitant。 3．句意：但我最好的朋友莉莉，已经是成员了，说服我试一试。 根据“my best friend”及后文作者确实加入了可知，朋友是友好地“说服”，故选persuaded。 4．句意：当我们到达时，看到到处散落着这么多塑料垃圾，我很震惊。 根据“so much plastic waste scattered everywhere”可知，垃圾之多令人“震惊”，故选shocked。 5．句意：结束时，我的背疼且手脏，但当我看着我们创造的干净海滩时，我感到强烈的自豪感。 根据前文身体疲惫与后文心理满足形成对比，需用转折连词“但是”，故选but。 6．句意：结束时，我的背疼且手脏，但当我看着我们创造的干净海滩时，我感到强烈的自豪感。 根据“clean beach we had created”可知，劳动成果带来的是“自豪”，故选pride。 7．句意：我们在学校组织了一场“无一次性塑料”活动，鼓励学生带可重复使用的水瓶和饭盒。 根据“campaign”及环保活动性质可知，目的是“鼓励”学生参与，故选encouraging。 8．句意：我们还设立了回收角，教每个人如何正确分类垃圾。 根据“recycling corner”可知，回收需要“分类”垃圾，故选sort。 9．句意：看着小树直立在地下，我意识到每一个小小的努力都很重要。 根据前文“dig holes and carry saplings”可知，这是付出的“努力”，故选effort。 10．句意：环保不是独自做大事，而是关于我们日常生活中的小改变。 根据“small changes”及环保习惯的养成可知，指的是“日常”生活，故选daily。 11．句意：最重要的是，我培养了一种保护地球的责任感。 根据全文作者的成长历程可知，责任感是逐渐“培养”出来的，故选developed。 12．句意：我曾经是那个会逃避环境问题的人，但现在我很自豪成为一名生态志愿者。 根据run away from意为“逃避”，符合前文不想加入俱乐部的心态，故选run。 13．句意：如果每个人都做出小小的努力，我们就能给世界带来巨大的改变。 根据前后句逻辑关系，此处为条件状语从句，表示“如果”，故选If。 14．句意：我将继续尽我所能来保护环境，我希望更多人能加入我们。 根据“Eco-Club”及上下文语境，邀请他人成为成员用“加入”，join准确体现参与俱乐部，故选join。 15．句意：我们一起，就能为 我们自己 建设一个更绿色、更美丽的未来。 根据主语“we”可知，反身代词应保持一致，用“我们自己”，故选ourselves。 学科网（北京）股份有限公司 $
