My research centred on investigating the presence and impact of bacteria in different water sources, specifically comparing wild lake water with home pool water to determine which was more harmful. This topic interested me because it combined both environmental science and public health, two topics I'm deeply passionate about. 　　The laboratory work was challenging but extremely rewarding. I remember the first day I set out to collect water samples(样本). The lake was peaceful, but beneath the calm surface hid something far less harmless. In contrast, the pool's crystal-clear water seemed almost too clean, and I wondered how the tests would turn out. 　　Back in the lab, I analyzed the samples. The process involved culturing the bacteria, monitoring their growth and comparing the results from both sources. When the data were finally generated, they were both shocking and enlightening. The lake water, despite its beautiful appearance, was full of bacteria—definitely not safe for drinking. On the other hand, the pool water was surprisingly clean, with hardly any bacteria present. These results highlighted the importance of clean water and sanitation(卫生设施体系) and the hidden dangers that untreated water can pose. 　　Once my experiments were completed, I poured all my energy into writing a detailed report. I wanted to make sure that my findings were clear and accurate to convey the significance of the research. On the last day of the seminar, I had the opportunity to present my work to a group of 15 mentors. Standing before them, explaining my project, I felt proud—I was not just a student; I was like a scientist sharing my discoveries with the world. 24.How did the author think of the wild lake water? A.Harmless.　　　B.Challenging. C.Beautiful.　　　D.Clean. 25.What was the first step of the research? A.Culturing the bacteria. B.Monitoring bacteria's growth. C.Comparing the results. D.Collecting water samples. 26.What does the underlined word “enlightening” in paragraph 3 mean? A.Ever-lasting.　　　B.Educational. C.Interesting.　　　D.Life-changing. 27.What does the author's experience show? A.Seeing is not believing. B.Practice makes perfect. C.Still waters run deep. D.Easier said than done. C 　　Of all the creatures on the planet, the narwhal(独角鲸) has the strangest appearance. It's a whale which has a long tooth coming out of its head; that's how it got its nickname, the unicorn(独角兽) of the sea. They live in the Arctic Ocean off the coast of Canada, Russia and East Greenland. However, experts say some populations of narwhals could be extinct, and it's all due to noise pollution. 　　Narwhals rely on echolocation(回声定位), which they use to find food and detect their surroundings. They produce a sound wave that travels through water until it encounters an object. They receive this reflected sound with their lower jaws, and obtain the information on features like size and shape. 　　However, the increase in human activities in the sea, as well as climate change, has resulted in the Arctic Ocean becoming noisier, which means it's more difficult for narwhals to rely on sound. Susanna Blackwell, who studies the effects of underwater noise on sea animals, told the BBC that there is noisier activity in the Arctic Ocean than ever because, as sea ice melts, new routes are opening. And while icebergs' breaking has been part of the ocean sound for hundreds of years, man-made noise is much harder for animals to adapt to, particularly as these changes are so sudden. 　　Research in 2023 recorded the reactions of narwhals to the imitated noises made by a guard ship. The scientists marked and tracked the creatures and found that, on hearing these sounds, they ended deep dives and stopped clicking, the echolocation signal they use for finding food underwater. This is the same reaction that narwhals have to orcas(虎鲸), which hunt them, meaning man-made noise could touch the creature's “threat button”. 　　So, what can we do? Charlotte Findlay, a assistant professor at Heriot-Watt University, says, “Noise is actually quite easy to solve. We need to either turn it off or turn it down.” 28.What can be the main factor in causing the extinction of narwhals? A.Its hunters.　　　B.Noise pollution. C.Its strange appearance.　　　D.Climate change. 29.How does a narwhal detect its surroundings? A.By its long tooth. B.By diving deeper. C.By echolocation. D.By listening to the a sound. 30.Why is it difficult for narwhals to rely on sound? A.Sea animals affect narwhals' activities. B.The Arctic Ocean is noisier than before. C.Human activities cause climate change. D.Narwhals can easily adapt to sudden changes. 31.What is the best title for the text? A.The Survival Threat to the Narwhal B.Great Power of Echolocation C.Strange Appearance of the Narwhal D.Effective Ways to Reduce Noise Pollution D 　　Built in 1990, the Moriyama City Firefly Forest Museum has been trying to recover the number of the Genji firefly(源氏萤火虫), whose population was near extinction in the first half of the 20th century. 　　In Japan, fireflies have long been the sign of summer. Moriyama's Genji fireflies are especially prized for their vivid, yellow-green glow. However, from 1868 to 1912, a commercial firefly industry developed. In just one night, a single hunter could catch about as many as 3,000 fireflies, sweeping the earth with brushes to frighten just egg-laying fireflies from riverbanks. It was easiest to catch female fireflies when they laid their eggs. Thus, there were fewer and fewer left to produce the next generation. At the same time, rapid urbanization of Japan was turning Moriyama's once ideal habitats into places where few fireflies could survive. Concrete was laid on the banks where there was once grass. Wastewater ran into the waters where the larvae(幼虫) grew. 　　The founders set the museum in the kind of habitat that Genji fireflies would find attractive. They created an artificial river and planted its banks with grass. Inside the museum, they mate and reproduce Genji fireflies. It is still the only organization to do so on a large scale. Fireflies lay thousands of eggs. When the larvae come out, they are moved to boxes with flowing water. They grow there until February when the larvae are moved to the man-made river. Then, the fireflies leave the water and take flight in June. 　　The museum also has educational purposes. Throughout the year, they lecture on the insect's history and ecology in schools. They also lead museum activities and other training and awareness campaigns, including the museum's magazine, From the Firefly Forest. Cleanup activities around waters are also organized. 　　The action is reasonable but, despite their efforts, the number of Genji fireflies hasn't increased so much in Moriyama. Most other habitats continue to become worse due to urbanization. Unless people preserve them, fireflies will continue to suffer. “The only chance to recover the Genji firefly's population is to act now,” ecologist Dai-ichiro Kato warns. “We're running out of time to provide the environmental education to save Japan's beloved glowing insect.” 32.Why did the number of the Genji fireflies decrease? A.Because the banks where they once lived disappeared. B.Because the waters where the larvae grew were polluted. C.Because over 3,000 female fireflies were caught every night. D.Because a commercial firefly industry developed their habitats. 33.What efforts has the Firefly Forest Museum made? A.It has organized various educational activities. B.It has helped Genji fireflies lay thousands of eggs. C.It has helped Genji fireflies leave the water and take flight in June. D.It has created the kind of habitat that the Genji fireflies would find attractive. 34.What does Kato think of the task of recovering the Genji firefly's population? A.It is reasonable. B.It makes no sense. C.It wastes lots of time. D.It needs immediate action. 35.What is the text mainly about? A.The extinction of Genji fireflies in Japan. B.The reappearance of Genji fireflies in Japan. C.Efforts made to recover Genji fireflies by a Japanese museum. D.The effect of urbanization on Japan's favorite glowing insect. 第二节(共5小题;每小题2.5分,满分12.5分) 　　阅读下面短文,从短文后的选项中选出可以填入空白处的最佳选项。选项中有两项为多余选项。 　　All animals exist in a network, supported by each other. That's why our global focus today should be on saving animals from extinction. By doing so, we are certainly keeping an ecological balance. 　36　.  　　Support companies that promote environmental protection 　　When shopping either from your local or online stores, go for those companies with eco-friendly things. Whether you are looking for shoes, toys, bags or others, you can choose reusable products. 　37　.  　　Avoid harmful pesticides 　　Harmful pesticides have resulted in heavy loss of animal life. They might be good for killing pests. 　38　. The chemicals enter into the soil and last a long time, thus endangering native wildlife species. Worse, they spread throughout the food, causing damage to other large animals.  　　　39　  　　Don't buy things made of horns, ivory and others that endanger animals. This saves the animals and their habitats. Be careful when buying souvenirs on the trip. Some could be made from endangered animal products like ivory. It's important to research the product before you make the decision to buy. 　　Drive carefully 　　This is one of the easiest things you can do to join in animal protection. 　40　. This will help reduce the road danger to endangered wildlife. Reducing car speed can reduce the animal accidents as much as possible.  A.Buy fewer products B.Avoid buying products harmful to animals C.Here are what you can do to save endangered species D.When driving near forests or animal reserves, don't go fast E.Sadly, they also leave a lasting terrible effect on native species F.These products help reduce the damage to forests or animal habitats G.Avoiding the use of these chemicals can help save endangered animals 36.　　　　37.　　　　38.　　　　39.　　　　40.　　　  第三部分　语言运用(共两节,满分30分) 第一节(共15小题;每小题1分,满分15分) 　　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。 　　It's 6:15 a.m. on a school day.

Eight-year-old Alice began to get nervous, the way she always did in new surroundings. She felt a thin shine of sweat above her lip in spite of the car's cool air. “The aquarium(水族馆) won't be crowded, I bet, and people are going to notice me. I hate wearing this prosthetic leg(假肢),” she thought to herself. “Not being normal is the worst.” She felt tears coming from her eyes. 　　Entering the Clearwater Marine Aquarium, around a corner of a tank, she noticed an animal that looked unusual. “Is that a dolphin with a prosthetic tail instead of a real tail?” she asked an aquarium staff member. He nodded and replied, “Yes, that's Betty. She's a very special dolphin.” “What happened to her?” “This dolphin was found off the coast of Florida, caught in a crab trap. The ropes from the trap cut off the blood circulation to her tail. So she lost her tail.” Alice caught her breath. “She's just like me.” “But she struggled to survive. Now she wears a prosthetic tail to help her swim as a dolphin's supposed to swim,” the staff member continued. “Every day, Betty shows us anything is possible if we believe in ourselves.” 　　Alice felt her heart was touched. She waved at Betty. Looking at Alice, Betty raised her flippers(鳍), came to her and lifted her head. “She's swimming right into my arms,” Alice said tearfully. They made eye contact. She seemed to be speaking to Alice, “We're the same.” 　　Back home, all Alice talked about was Betty. For two weeks, she cried and begged her mother to take her back to Clearwater. 　　Unfortunately, another blow hit Alice. She fell on the hardwood floor at home and broke her other leg. Alice suffered the pain in her leg. After a thorough examination, the doctor explained bad news to them that she would need some surgery on her leg. Years of a living hell(地狱) came back to her. 　　She started fearing surgery again and refused to go to hospital for treatment. 注意:续写词数应为150个左右。 “How can I persuade Alice to undergo the surgery?”Alice's

35.C　主旨大意题。分析文章结构可知,第一段介绍了守山市萤火虫森林博物馆在为恢复源氏萤火虫的数量努力,第二段介绍了源氏萤火虫的现状,第三、四段介绍了该博物馆为恢复源氏萤火虫的数量所采取的措施,第五段则总结了该博物馆所做的努力并呼吁大家一起拯救源氏萤火虫。所以推知文章主要是关于该博物馆为恢复源氏萤火虫的数量所做的努力。故选C。 第二节 　　◎语篇解读　本文是一篇说明文。文章主要介绍了如何保护濒危野生动物。 36.C　根据上文可知,拯救濒临灭绝的动物应该是如今全球的焦点,通过这样做可以保持生态平衡;而下文介绍了如何拯救濒危物种。所以C项“这里是你可以做的用来拯救濒危物种的事情”承上启下,符合语境。故选C。 37.F　设空处在段末,应承接上文,上文提到无论你是在找鞋子、玩具、包包还是其他东西,你都可以选择可重复使用的产品,F项“这些产品有助于减少对森林或动物栖息地的破坏”符合语境,说明选择可重复使用的产品的原因。选项中的These products指代的是上文中的reusable products。故选F。 38.E　根据上文可知,有害的杀虫剂导致大量动物死亡,它们可能对杀害虫很有效,根据下文可知,这些化学物质进入土壤并持续存在很长时间,从而危及当地的野生动物物种,更糟糕的是,它们会扩散到食物中,对其他大型动物造成损害,所以E项“不幸的是,它们也给本土物种留下了持久的可怕影响”符合语境,选项中的they指代上文中的harmful pesticides,选项中的lasting和下文中的last a long time相呼应,故选E。 39.B　设空处是本段小标题。本段提到不要买由动物的角、象牙等制成的物品,B项“避免购买对动物有害的产品”符合本段主旨。故选B。 40.D　下文提到了降低车速,所以D项“在森林或动物保护区附近开车时,不要开得太快”引起下文,符合语境。故选D。 第三部分　语言运用 第一节 　　◎语篇解读　本文是一篇记叙文。文章主要叙述了一个名为plogging的边慢跑边捡垃圾的活动,人们可以在享受跑步的乐趣的同时为保护环境尽一份力。 41.C　根据“It's 6:15 a.m.”和常识可知,早上的时候天会逐渐变亮,故选C。 42.B　Murzycki没有多睡几分钟,反而做了另一件事情,故选B。 43.D　根据下文“a litter grabber”可知plogging是一项边跑步边捡垃圾的活动,故选D。 44.B　根据下文“a litter grabber and a reusable shopping bag”可知,去捡垃圾需要一些必需的东西,故选B。 45.C　由上文可知,购物袋的一边装要送到垃圾填埋场的垃圾,结合选项可知另一边应该装可回收利用的垃圾,形成对比,故选C。 46.D　根据下文“Within a few hours the street will be littered with rubbish again.”可知,Murzycki是有意在主街上跑步的,因为主街上垃圾多,故选D。 47.A　结合语境可知,跑步过程中Murzycki不断捡垃圾,中途袋子会满,所以她需要中途停下清空袋子,故选A。 48.A　根据下文“it just gives more energy to her plogging”可知,几个小时后,街上又会充满垃圾,但这并没有阻挠她,而是给她带来动力,故选A。 49.B　根据下文“two Swedish words that mean ‘pick up' and ‘jog'”可知,“plogga”是两个单词组合形成的,故选B。 50.A　根据下文“he felt...began gathering friends to clean up the neighborhood while out for runs”可知,Erik Ahlström开始召集朋友们外出跑步时清理附近的垃圾。由此可知,这项运动是由Erik Ahlström发起的,故选A。 51.D　由下文他开始召集朋友们捡垃圾可知,垃圾的数量很多,令他感到大为惊奇,故选D。 52.C　根据上文可知,Ahlström先生现在正在环游世界,此处应该指宣传plogging的益处,故选C。 53.D　根据语境推断,此处指社交媒体和跑步群体鼓励人们出去一边跑步一边捡垃圾,故选D。 54.A　根据下文“But she has...make it fun”可知,本空应与fun意思相反,boring表示“无聊的”,符合语境,故选A。 55.C　根据下文的“one push-up”可知,此处表示“锻炼”,故选C。 第二节 　　◎语篇解读　本文是一篇说明文。文章主要介绍了汤圆的起源、发展以及所代表的意义。 56.deeply　考査副词。此处修饰形容词rooted,应用副词。故填deeply。 57.which　考查定语从句。分析句子结构可知,设空处引导非限制性定语从句且在从句中作主语,先行词指物,所以应用关系代词which引导。故填which。 58.meaningful　考查形容词。设空处修饰名词dish,应用形容词,表示“重要的;有意义的”。故填meaningful。 59.was made　考查动词的时态、语态和主谓一致。设空处为从句谓语,make与其主语it之间为被动关系,结合上文的appeared可知,此处应用一般过去时的被动语态,主语为it,助动词应用was。故填was made。 60.while　考查连词。句意:当这一传统传到中国北方时,它与元宵节有了关联,被称为元宵,而南方则保留了汤圆的名字。设空处前后为对比关系,应用连词while,表示“而,然而”。故填while。 61.has changed　考查动词的时态和主谓一致。根据时间状语Over time和语境可知,此处应用现在完成时,强调过去的动作对现在有影响,主语为Tangyuan,助动词应用has。故填has changed。 62.varieties　考查名词的数。设空处作宾语,根据语境可知,此处variety意为“品种”,是可数名词,根据本句中的“such as chocolate and fruit jams”可知,此处应用复数形式。故填varieties。 63.stressing　考查现在分词。句中已有谓语动词,此处需用非谓语形式,动词stress与逻辑主语The process of making Tangyuan之间为主动关系,所以用现在分词作状语。故填stressing。 64.to enjoy　考查动词不定式。句中已有谓语动词gather,根据语境可知,“家庭团聚”的目的是“享用汤圆”,此处应用动词不定式作目的状语。故填to enjoy。 65.a　考查冠词。句意:它还通过传统和创意的融合反映了文化价值,仍然是人们喜爱的团圆的象征。symbol为可数名词,此处泛指“一个深受喜爱的象征”,应用不定冠词,beloved的发音以辅音音素开头。故填a。 第四部分　写作 第一节 One possible version: Protect animals 　　Animals play a vital role in maintaining an ecological balance.They contribute to healthy ecosystems, which humans rely on for clean air, water, and food. Protecting them ensures our own survival and preserves biodiversity. 　　However, humans harm animals in many ways. Some hunt them for fur or ivory, while others destroy their habitats through deforestation and pollution. These actions can drive many species to the edge of extinction. 　　To protect animals, governments should enforce strict laws against hunting and habitat destruction. Individuals can help by refusing to buy products made of wild animals and raising awareness of protecting animals. Together, we can create a safer world for all creatures. 第二节 One possible version: 　　“How can I persuade Alice to undergo the surgery?”Alice's mom said to herself. Then she had an idea and she decided to take Alice back to Clearwater. On arriving at Clearwater, Alice couldn't wait to see Betty, the lovely dolphin that comforted her and boosted her mood. As Alice's mother wheeled Alice towards Betty, she raised her flippers, came to them and lifted her head. Looking at the girl, Betty seemed to say, “Be brave and believe in yourself.” Alice absolutely knew what the caring eyes were conveying, so she decided to keep a more optimistic state of mind. 　　Encouraged by Betty, Alice changed her mind and did what her mother and doctor had told her to. Finally came the day when Alice was in the hospital again. Though feeling nervous and afraid of the pain the surgery might bring, Alice faced it bravely. The operation was a success. Her mother took her to Clearwater on the day when she was discharged from hospital. Inspired by Betty's swimming like a normal dolphin, Alice practiced walking hard. Her confidence had been improved as she gradually recovered. She had no idea what her future would be like but she would do anything to have a better look at this wonderful world. 学科网（北京）股份有限公司 $ UNIT 1 Nature in the balance 第一节 听下面5段对话。每段对话后有一个小题，从题中所给的A、B、C三个选项中选出最佳选项。听完每段对话后，你都有10秒钟的时间来回答有关小题和阅读下一小题。每段对话仅读一遍。 【Text 1】 W: I have to take a bus to the City Library.

Just watching him run got me motivated. I quit being a chess player and started to run. I went to the 2016 Olympics, and went to the finals at the age of 18. And, wow, I finished fifth. It was a dream come true to me, but I still wanted more. The training is super hard. But the hardest part for me is that I got an injury—an injury which may take me out for years. For a period of time, as a young athlete, I didn’t know what to do. I lost focus. But now, I’m back on the track. I really want to be there at the Olympics, and do what I did before; do much, much greater. I don’t care about the gold; I don’t care about the silver. I want to do my best.
