The world would be quieter without these birds! Can we save them in time? Name: Javan Green Magpie (短尾绿鹊) Country: Indonesia The birds don’t just look beautiful. They have amazing singing skills, too! Unluckily,this has made them very popular with people who keep wild birds as pets. Now people keep them in zoos,so the world doesn’t lose them. Name: Florida Grasshopper Sparrow (佛罗里达蝗雀) Country: USA They love eating grasshoppers (蝗虫), and their songs make them sound like grasshoppers, too! They almost lost their home many years ago. But over the past few years, their population has probably risen. Name: Regent Honeyeater (王吸蜜鸟) Country: Australia Because there aren’t enough adult (成年的) birds around, young birds don’t always get the chance to learn the songs to attract (吸引) a mate (伴侣). So, scientists are teaching young birds how to sing. They put them in cages (笼子) close to singing adults before sending the young birds into the wild. Name: Blue-crowned Laughingthrush (靛冠噪鹛) Country: China These birds are named after one of their calls, which sounds like someone laughing! But now people can find them only in a few places. People are trying their best to help them. The more information we have on these birds, the better chances of saving them we get! 26．How do scientists teach young Regent Honeyeaters to sing?

B In 2025, a group of scientists from the Chinese Academy of Sciences published an alarming report about the state of the world’s coral reefs. The report, which was based on data collected from over 2,000 locations worldwide, showed that more than 40% of the world's coral reefs have disappeared in the past 30 years. Coral reefs, often called the “rainforests of the sea” are home to about 25% of all marine species. They provide food and shelter for millions of sea animals. They also protect coastlines from storms and support the fishing industry. Yet rising ocean temperatures, pollution, and overfishing are destroying them at an alarming rate. Dr Li Wei, who has devoted more than 15 years to studying coral reefs, says the situation is serious but not hopeless. “If we act now, we can still save some of the reefs,” she says. “But we must reduce greenhouse gas emissions and stop overfishing immediately.” One successful example is the Great Barrier Reef Marine Park in Australia, where strict fishing controls have allowed some parts of the reef to recover. Similar conservation efforts in the South China Sea have also shown positive results. “Let us permit nature to have her way,” Dr Li says. “Without a healthy ocean, humans cannot survive either.” (Adapted from 21st Century Teens, 2026) 31．What does the report by the Chinese Academy of Sciences show? A．Coral reefs are growing faster than before. B．More than 40% of coral reefs have disappeared in 30 years. C．Coral reefs are not important to marine life. D．Overfishing has stopped completely. 32．Why are coral reefs called the “rainforests of the sea”? A．Because they are found in rainforests. B．Because they have many trees. C．Because they are very large. D．Because they are home to many species. 33．According to Dr Li Wei, what should we do to save coral reefs? A．Stop fishing completely. B．Build more parks. C．Reduce greenhouse gas emissions and stop overfishing. D．Move all animals to other places. 34．What is the example of successful conservation mentioned in the passage? A．The Great Barrier Reef Marine Park. B．The Amazon Rainforest. C．The Giant Panda National Park. D．The South China Sea Fishing Area. 35．What is the main message of this passage? A．Coral reefs are not worth saving. B．Protecting coral reefs is important for humans too. C．Technology can solve all environmental problems. D．The ocean will recover by itself. C Climate change is influencing ecosystems all over the world, and mountain areas are facing some of the fastest changes. A new study from the Chinese Academy of Sciences shows that the warming temperature on the Qinghai-Tibet Plateau is changing the balance of the mountain ecosystem. Over the past 50 years, the average temperature on the plateau has risen by 1.5℃, which is faster than the world average. The rising temperature makes the snowline move higher up the mountain. Many tiny plants that live in cold high areas are losing their living space. At the same time, some lowland plants are moving higher and taking the place of the original cold climate plants. If this continues, about 30% of the endangered alpine plants on the plateau will disappear by 2100. This will also influence the animals that depend on these plants for food and homes. Scientists say this is a serious warning that the fine ecological balance of the whole plateau is in danger. The study also highlights some good news. China’s national protection projects have slowed down the speed of change. Local environmental protection teams have collected seeds of endangered alpine plants and planted them in protected areas. They are also working to cut down negative human activities like over-grazing and illegal mining. “Climate change is a big challenge, but we can still do something to protect the balance. The key is to act early before it is too late,” said the lead scientist of the study. 36．Where did the new study come from? A．Peking University. B．The Chinese Academy of Sciences. C．Peking Union Medical College. D．Xishuangbanna Research Center. 37．How much has the average temperature on the Qinghai-Tibet Plateau risen over the past 50 years? A．0.5℃. B．1.0℃. C．1.5℃. D．2.0℃. 38．Why are lowland plants moving higher up the mountain? A．Because the temperature is getting warmer. B．Because the snowline is moving lower. C．Because people plant them on the mountain. D．Because the lowland has no more space for them. 39．Which of the following is a good action that China has taken to protect the alpine plants? A．Cutting down the number of animals on the plateau. B．Building new farms for lowland plants. C．Collecting seeds of endangered plants and planting them in protected areas. D．Stopping all human activities on the plateau. 40．What is the main message of the text? A．Climate change has already destroyed all the mountain ecosystems. B．There is nothing we can do to stop the change of mountain ecosystems. C．Warming temperature changes mountain ecosystems, but we can act. D．All alpine plants on the Qinghai-Tibet Plateau will disappear by 2100. 四、单词拼写（本大题共10题，每题1分，共10分） 41．Trees would grow freely without the danger of ________ (cut) down. 42．These natural wonders ________ (hide) by smog for many years. 43．The rules that ________ (protect) nature are necessary. 44．The ________ (pollute) of the river is a serious problem. 45．The success in protecting pandas is ________ (undoubted) encouraging. 46．We need to protect these ________ (endanger) animals. 47．Many kinds of plants failed ________ (survive) in bad environment. 48．Without ________ (act), we will only see beautiful sea animals in museums. 49．Many animals ________ (live) in the sea are disappearing. 50．It is ________ (admire) of him to help others without asking for anything in return. 五、选词填空（本大题共5题，每题1分，共5分） 选用方框中的短语填空 that、which、who、whom、whose、where Nature is like a big family.

It is home to many rare wild animals, 61 (include) the Tibetan antelope. In the 1990s, 62 rapid development of the wool trade made many poachers (偷猎者) kill Tibetan antelopes for their fur. As a result, the number of Tibetan antelopes dropped 63 low that the species was listed as endangered. Over the past 30 years, Chinese 64 (organise) have been working hard on the protection of this fragile ecosystem. Strict rules forbid poaching and stop 65 (industry) activities from destroying the antelopes’ living areas. Furthermore, more and more local people have joined volunteer groups to help 66 (monitor) the antelope population. The protection efforts have achieved great success: the number of Tibetan antelopes 67 (grow) from less than 70,000 in 1995 to over 300,000 in 2024. This story tells us that human activities can have both negative and positive 68 (influence) on nature. When we keep a good balance between development and 69 (protect), we can live in harmony with wild animals. This experience 70 (highlight) the importance of protecting the natural world for future generations. 八、任务型阅读（本大题共5题，每题1分，共5分） Rivers are one of our most important natural resources. Many of the world’s great cities are next to rivers, and almost every country has at least one river flowing (流过) through. That plays an important part in the lives of its people. Most rivers begin in mountains and end in oceans. Since the beginning of history, people have used rivers for transportation. The longest one in the US is the Mississippi. The lifeline of Egypt is the Nile. To the people of India, the Ganges is great. Ships can travel along it for a thousand miles. The greatest of all for navigation (航海), is the Amazon in Brazil. It is so wide and so deep that large ships can go about two thousand miles upon it. Besides transportation, rivers give food to eat, water to drink and water for crops (庄稼). In order to increase the supply of water for crops, engineers sometimes build a dam (大坝) across a river. Then people can use the water not only to irrigate (灌溉) their fields but also to make electricity for their homes and industries. However, large cities and industries that are next to rivers often have problems. As the cities grow in size and industries increase in number, the water in the rivers becomes polluted. People have realized the importance of protecting the rivers. They are doing more to keep their rivers clean. 71．What plays an important part in the lives of the people from the text? 72．How long have people used water for transportation? 73．Why is Amazon regarded as the greatest for navigation? 74．What do people use the water from the dam to do? 75．What do you think of protecting water resources? What will you do for it? 九、书面表达（本题10分） 请根据以下提示，写一篇关于生态保护成功案例的英文短文。 提示内容： 1. 你选择的动物或植物是什么？ 2. 它们过去面临什么问题和威胁？ 3. 人类活动对它们产生了什么影响？ 4. 现在它们的状况如何？ 5. 它们是如何得到保护的？ 6. 我们能从这个成功案例中学到什么？ 要求： 1. 词数不少于80词； 2. 结构清晰，包含所有要点； 3. 使用本单元所学的词汇和表达（如：endangered species，make great efforts，protected area，habitat，survival等）。 ____________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ 试卷第2页，共20页 试卷第5页，共20页 学科网（北京）股份有限公司 $ 2026-2027学年九年级上册英语单元自测- Unit 5 A fine balance·能力提升 学校:___________姓名：___________班级：___________分数：___________ （时间：90分钟，满分：100分） 一、单项选择（本大题共15题，每题1分，共15分） 1．—I don’t know how to ________ study and fun. —Don’t worry! Don’t spend too much time on computer games. A．know B．balance C．leave D．have 【答案】B 【详解】句意：——我不知道如何平衡学习和娱乐。——别担心！不要在电脑游戏上花费太多时间。 know知道；balance平衡；leave离开，留下；have有。根据答语“Don’t spend too much time on computer games.”可知，对方建议不要花太多时间在电脑游戏上，隐含之意是要协调好学习与娱乐的关系，即“平衡”。 2．For small businesses in this highly competitive market, ________ is becoming more and more challenging. A．survival B．prosperity C．improvement D．extinction 【答案】A 【详解】句意：对于在这个竞争激烈的市场中的小企业来说，生存正变得越来越具有挑战性。 survival生存；prosperity繁荣；improvement改进；extinction灭绝。根据“highly competitive market”可知市场竞争激烈，对于小企业而言，首要面临的困难是能否继续经营下去，即“生存”变得困难。应填survival。 3．The young birds are very ________ to cats and other predators. A．vulnerable B．strong C．safe D．protected 【答案】A 【详解】句意：幼鸟非常容易受到猫和其他捕食者的伤害。 vulnerable脆弱的/易受伤害的；strong强壮的；safe安全的；protected受保护的。根据句意，幼鸟面对捕食者应处于“脆弱、易受攻击”的状态，而“be vulnerable to”为固定搭配，表示“易受……伤害”。 4．________, this discovery will change the future of medicine. A．Undoubtedly B．Uncertainly C．Unluckily D．Gradually 【答案】A 【详解】句意：毫无疑问，这一发现将改变医学的未来。 Undoubtedly毫无疑问地；Uncertainly不确定地；Unluckily不幸地；Gradually逐渐地。根据“this discovery will change the future of medicine”可知，此处强调这一发现对医学未来影响的确定性，Undoubtedly符合语境。 5．The new stadium can hold ________ people as the old one. A．as twice many B．twice as many C．as many twice D．many as twice 【答案】B 【详解】句意：新体育场能容纳的人数是旧体育场的两倍。 英语中表示“是……的几倍”常用结构为“倍数 + as + 形容词/副词原级 + as”。此处修饰可数名词people，应用many，且倍数twice应放在第一个as之前，构成twice as many ... as结构。 6．It is no surprise ________ he won the first prize in the competition. A．that B．what C．which D．who 【答案】A 【详解】句意：他在比赛中获得一等奖并不令人惊讶。 that引导从句（无实义）；what什么；which哪一个；who谁。根据句子结构“It is no surprise...”可知，此处it是形式主语，真正的主语是后面的从句。从句“he won the first prize in the competition”结构完整，不缺成分，且陈述的是一个事实，应用that引导主语从句。 7．The ________ development of industry has caused many environmental problems in this mountain area. A．rapid B．slow C．smooth D．sudden 【答案】A 【详解】句意：工业的快速发展在这个山区引发了许多环境问题。 rapid快速的；slow缓慢的；smooth平稳的，顺利的；sudden突然的。根据空后“development of industry has caused many environmental problems”可知，此处是固定搭配rapid development，意为“快速发展”。结合句意逻辑，工业的快速发展在这个山区引发了许多环境问题，因此空处应用rapid。 8．If we don’t stop cutting down trees, the ecological balance ________ be destroyed. A．must B．should C．might D．need 【答案】C 【详解】句意：如果我们不停止砍伐树木，生态平衡可能会被破坏。 must“一定”，表示有把握的推测；should“按道理说应该”，根据一定的依据进行推测；might“可能”，表示推测，其可能性不大；need“需要”。根据“If we don’t stop cutting down trees, the ecological balance...be destroyed.”可知，这是一个条件状语从句，主句表示对将来情况的推测，如果不这样做，生态平衡“可能”会被破坏，表示可能性，might符合语境，must语气过于绝对。 9．The ecosystem ________ is made up of plants and animals needs to stay in good balance. A．who B．whose C．whom D．which 【答案】D 【详解】句意：由动植物构成的生态系统需要保持良好的平衡。   who用来指代人，在从句中作主语；whose表示“谁的”，表所属关系；whom指代人，在从句中作宾语；which指代事物，在从句中作主语/宾语。在这个定语从句中，先行词“The ecosystem”（生态系统）是事物，要用关系代词which；其余三个都不能指代事物“ecosystem”。应填which。 10．Too much rubbish will ________ the river and ________ the living things inside. A．harm; affect B．affect; benefit C．protect; harm D．benefit; punish 【答案】A 【详解】句意：太多垃圾会伤害这条河流，并且影响里面的生物。 harm伤害，损害（对事物造成破坏）；affect影响；benefit使受益；protect保护；punish惩罚。根据“rubbish”、“the river”和“the living things”可知，垃圾给河流以及水生生物带来的都是负面影响，所以第一空应填harm，第二空应填affect。 11．People must stop ________, or many fish will die out soon. A．overfishing B．logging C．dropping D．marking 【答案】A 【详解】句意：人类必须停止过度捕捞，否则许多鱼类很快将会灭绝。 overfishing过度捕捞；logging伐木；dropping掉落；marking做记号。根据后半句“or many fish will die out soon”可知，大量鱼类即将灭绝，过度捕捞是造成鱼类消亡的原因，overfishing符合语境。 12．The ________ of this wildlife group can be seen on its uniform. A．alarm B．logo C．farmland D．wonder 【答案】B 【详解】句意：这个野生动物保护小组的标识可以在它的制服上看到。 alarm警报；logo标识，标志；farmland农田；wonder奇迹。根据“on its uniform”可知，能印在制服上的是组织标识，应填logo。 13．Plastic rubbish will ________ the living environment of sea animals. A．benefit B．harm C．protect D．mark 【答案】B 【详解】句意：塑料垃圾将会损害海洋动物的生存环境。 benefit对……有益；harm伤害，损害；protect保护；mark标记。结合常识可知塑料垃圾会破坏海洋生物生存环境，应填 harm。 14．Tom didn’t go to bed ________ his mother came back last night. A．till B．if C．because D．unless 【答案】A 【详解】句意：昨晚，汤姆直到他妈妈回来才上床睡觉。 till直到……为止；if如果；because因为；unless除非。分析句子可知，此处指汤姆直到妈妈回来才上床睡觉。故选A。 15．Scientists ________ to save the endangered pandas by setting up protected areas. A．make great efforts B．take actions C．set up D．benefit from 【答案】A 【详解】句意：科学家们通过建立保护区，努力拯救濒危的大熊猫。 make great efforts做出巨大努力；take actions采取行动；set up建立；benefit from从……中受益。根据句中“to save the endangered pandas”以及“by setting up protected areas”可知此处强调科学家们为达成目标而付出的艰辛和努力，“make great efforts to do sth.”意为“努力做某事”，符合语境和搭配习惯。 二、完形填空（本大题共10题，每题1分，共10分） Water is one of the most useful things on earth. We drink it, wash with it and cook with it. However, it can be 16 sometimes. This was something that happened to me a few months ago. It started as a normal school day. It was summer and the 17 was really hot. We were studying for our exams when a 18 came. The sky went dark and the rain started to beat heavily against the windows. The rain went on and on. Then, it started to come through the 19 and fall on the desks in the classroom. Without any 20 , our books were getting wet. Suddenly there was a loud sound. We didn’t 21 what it was at first.

The report, which was based on data collected from over 2,000 locations worldwide, showed that more than 40% of the world's coral reefs have disappeared in the past 30 years. Coral reefs, often called the “rainforests of the sea” are home to about 25% of all marine species. They provide food and shelter for millions of sea animals. They also protect coastlines from storms and support the fishing industry. Yet rising ocean temperatures, pollution, and overfishing are destroying them at an alarming rate. Dr Li Wei, who has devoted more than 15 years to studying coral reefs, says the situation is serious but not hopeless. “If we act now, we can still save some of the reefs,” she says. “But we must reduce greenhouse gas emissions and stop overfishing immediately.” One successful example is the Great Barrier Reef Marine Park in Australia, where strict fishing controls have allowed some parts of the reef to recover. Similar conservation efforts in the South China Sea have also shown positive results. “Let us permit nature to have her way,” Dr Li says. “Without a healthy ocean, humans cannot survive either.” (Adapted from 21st Century Teens, 2026) 31．What does the report by the Chinese Academy of Sciences show? A．Coral reefs are growing faster than before. B．More than 40% of coral reefs have disappeared in 30 years. C．Coral reefs are not important to marine life. D．Overfishing has stopped completely. 32．Why are coral reefs called the “rainforests of the sea”? A．Because they are found in rainforests. B．Because they have many trees. C．Because they are very large. D．Because they are home to many species. 33．According to Dr Li Wei, what should we do to save coral reefs? A．Stop fishing completely. B．Build more parks. C．Reduce greenhouse gas emissions and stop overfishing. D．Move all animals to other places. 34．What is the example of successful conservation mentioned in the passage? A．The Great Barrier Reef Marine Park. B．The Amazon Rainforest. C．The Giant Panda National Park. D．The South China Sea Fishing Area. 35．What is the main message of this passage? A．Coral reefs are not worth saving. B．Protecting coral reefs is important for humans too. C．Technology can solve all environmental problems. D．The ocean will recover by itself. 【答案】31．B 32．D 33．C 34．A 35．B 【导语】本文介绍了全球珊瑚礁面临的严峻生存现状：2025年中国科学院科学家发布报告显示，过去30年全球已有超过40%的珊瑚礁消失。 【详解】31．根据第一段第二句“The report... showed that more than 40% of the world’s coral reefs have disappeared in the past 30 years.”可知，该报告显示过去30年里世界上超过40%的珊瑚礁已经消失。 32．根据第二段第一句“Coral reefs, often called the ‘rainforests of the sea’ are home to about 25% of all marine species.”可知，珊瑚礁被称为“海洋雨林”是因为它们是约25%海洋物种的家园，生物多样性丰富。 33．根据第三段李伟博士的话“But we must reduce greenhouse gas emissions and stop overfishing immediately.”可知，为了拯救珊瑚礁，我们需要减少温室气体排放并立即停止过度捕捞。 34．根据第四段第一句“One successful example is the Great Barrier Reef Marine Park in Australia...”可知，文中明确提到的成功保护例子是澳大利亚的大堡礁海洋公园。 35．根据最后一段李伟博士的总结“Without a healthy ocean, humans cannot survive either.”以及全文关于珊瑚礁重要性及保护措施的描述，可知文章主要传达了保护珊瑚礁对人类生存也至关重要的信息。 C Climate change is influencing ecosystems all over the world, and mountain areas are facing some of the fastest changes. A new study from the Chinese Academy of Sciences shows that the warming temperature on the Qinghai-Tibet Plateau is changing the balance of the mountain ecosystem. Over the past 50 years, the average temperature on the plateau has risen by 1.5℃, which is faster than the world average. The rising temperature makes the snowline move higher up the mountain. Many tiny plants that live in cold high areas are losing their living space. At the same time, some lowland plants are moving higher and taking the place of the original cold climate plants. If this continues, about 30% of the endangered alpine plants on the plateau will disappear by 2100. This will also influence the animals that depend on these plants for food and homes. Scientists say this is a serious warning that the fine ecological balance of the whole plateau is in danger. The study also highlights some good news. China’s national protection projects have slowed down the speed of change. Local environmental protection teams have collected seeds of endangered alpine plants and planted them in protected areas. They are also working to cut down negative human activities like over-grazing and illegal mining. “Climate change is a big challenge, but we can still do something to protect the balance. The key is to act early before it is too late,” said the lead scientist of the study. 36．Where did the new study come from? A．Peking University. B．The Chinese Academy of Sciences. C．Peking Union Medical College. D．Xishuangbanna Research Center. 37．How much has the average temperature on the Qinghai-Tibet Plateau risen over the past 50 years? A．0.5℃. B．1.0℃. C．1.5℃. D．2.0℃. 38．Why are lowland plants moving higher up the mountain? A．Because the temperature is getting warmer. B．Because the snowline is moving lower. C．Because people plant them on the mountain. D．Because the lowland has no more space for them. 39．Which of the following is a good action that China has taken to protect the alpine plants? A．Cutting down the number of animals on the plateau. B．Building new farms for lowland plants. C．Collecting seeds of endangered plants and planting them in protected areas. D．Stopping all human activities on the plateau. 40．What is the main message of the text? A．Climate change has already destroyed all the mountain ecosystems. B．There is nothing we can do to stop the change of mountain ecosystems. C．Warming temperature changes mountain ecosystems, but we can act. D．All alpine plants on the Qinghai-Tibet Plateau will disappear by 2100. 【答案】36．B 37．C 38．A 39．C 40．C 【导语】本文主要介绍了气候变暖对青藏高原山地生态系统造成的影响，以及我国为保护当地生态平衡所采取的积极应对举措。 【详解】36．根据第一段中“A new study from the Chinese Academy of Sciences shows…”可知，这项新研究来自于中国科学院。 37．根据第二段中“Over the past 50 years, the average temperature on the plateau has risen by 1.5°C…”可知，过去50年来青藏高原的平均气温上升了1.5℃。 38．根据第二段中“The rising temperature makes the snowline move higher up the mountain…At the same time, some lowland plants are moving higher…”可知，气温上升使雪线向上移动，导致原本生活在低地的植物也随之向山的高处迁移，因此低地植物向高处迁移的原因是气温变暖。 39．根据第四段中“Local environmental protection teams have collected seeds of endangered alpine plants and planted them in protected areas.”可知，我国采取的保护措施包括收集濒危高山植物的种子并将它们种植在保护区内。 40．本文前三段阐述了气温变暖对山地生态系统造成的改变与威胁，后两段介绍了我国采取的积极保护措施并引用科学家的话指出“我们可以采取行动保护平衡”。高度概括全文可知，文章旨在阐明气温变暖改变了山地生态系统，但我们可以采取行动进行应对。 四、单词拼写（本大题共10题，每题1分，共10分） 41．Trees would grow freely without the danger of ________ (cut) down. 【答案】being cut 【详解】句意：树木会自由生长，没有被砍伐的危险。cut“砍伐”，动词；of为介词，后接动名词，且与“Trees”构成被动关系，故填being cut。 42．These natural wonders ________ (hide) by smog for many years. 【答案】have been hidden 【详解】句意：这些自然奇观多年来一直被雾霾所遮蔽。for many years是现在完成时的标志词，主语natural wonders和动词hide之间是被动关系，所以横线处用“现在完成时的被动语态”，结构为：have/has been done，主语wonders是复数，助动词用have，hide的过去分词是hidden。 43．The rules that ________ (protect) nature are necessary. 【答案】protect 【详解】句意：保护自然的规则是必要的。所给动词为protect“保护”，空格处需填入定语从句的谓语动词，先行词rules为复数，且描述一般事实，应用一般现在时，protect用原形。 44．The ________ (pollute) of the river is a serious problem. 【答案】pollution 【详解】句意：这条河流的污染是一个严重的问题。定冠词The后需要接名词作句子的主语，pollute是动词，意为“污染”，其名词形式为pollution，故填pollution。 45．The success in protecting pandas is ________ (undoubted) encouraging. 【答案】undoubtedly 【详解】句意：保护大熊猫的成功无疑是令人鼓舞的。空格位于系动词“is”和形容词“encouraging”之间，需用副词修饰“encouraging”，表示程度。“undoubted”为形容词，其副词形式为“undoubtedly”，意为“毫无疑问地”。 46．We need to protect these ________ (endanger) animals. 【答案】endangered 【详解】句意：我们需要保护这些濒危动物。endanger，动词，意为“使遭受危险；危及”；空格后面是名词“animals”，修饰名词要用形容词；endanger的形容词是endangered“濒危的”。 47．Many kinds of plants failed ________ (survive) in bad environment. 【答案】to survive 【详解】句意：许多种类的植物在恶劣环境中难以存活。句中用到固定搭配fail to do sth.（未能做某事），此处需要用动词不定式，故填to survive。 48．Without ________ (act), we will only see beautiful sea animals in museums. 【答案】action 【详解】句意：如果我们不采取行动，将来就只能在博物馆里看到美丽的海洋动物了。空格位于介词“Without”之后，需填名词作宾语。括号内“act”为动词，其名词形式为“action”，表示“行动”，与语境“如果不采取行动”吻合。 49．Many animals ________ (live) in the sea are disappearing. 【答案】living 【详解】句意：许多生活在海洋里的动物正在消失。句子已有谓语动词are disappearing，所以live不能作谓语。living in the sea是现在分词短语作后置定语，修饰Many animals，表示“生活在海里的许多动物”。 50．It is ________ (admire) of him to help others without asking for anything in return. 【答案】admirable 【详解】句意：他无私地帮助别人而不求回报，这令人钦佩。句中“It is + adj. + of sb.”为固定句型，表示“某人做某事是……的”，空格处应填形容词作表语，说明人的品质。admire的形容词形式有admirable（令人钦佩的）和admired（被钦佩的）。此处表示“令人钦佩的”，应用admirable，故填admirable。 五、选词填空（本大题共5题，每题1分，共5分） 选用方框中的短语填空 that、which、who、whom、whose、where Nature is like a big family.

It is home to many rare wild animals, 61 (include) the Tibetan antelope. In the 1990s, 62 rapid development of the wool trade made many poachers (偷猎者) kill Tibetan antelopes for their fur. As a result, the number of Tibetan antelopes dropped 63 low that the species was listed as endangered. Over the past 30 years, Chinese 64 (organise) have been working hard on the protection of this fragile ecosystem. Strict rules forbid poaching and stop 65 (industry) activities from destroying the antelopes’ living areas. Furthermore, more and more local people have joined volunteer groups to help 66 (monitor) the antelope population. The protection efforts have achieved great success: the number of Tibetan antelopes 67 (grow) from less than 70,000 in 1995 to over 300,000 in 2024. This story tells us that human activities can have both negative and positive 68 (influence) on nature. When we keep a good balance between development and 69 (protect), we can live in harmony with wild animals. This experience 70 (highlight) the importance of protecting the natural world for future generations. 【答案】61．including 62．the 63．so 64．organisations 65．industrial 66．to monitor/monitor 67．has grown 68．influences 69．protection 70．highlights 【导语】本文主要介绍了青藏高原上藏羚羊数量由减少到恢复的保护历程，强调了人类在发展与环境保护之间保持平衡的重要性。 【详解】61．句意：这里栖息着许多珍稀野生动物，其中包括藏羚羊。根据空前的完整主句“It is home to many rare wild animals”可知，此处需用介词引出包含的例子，表示“包括藏羚羊在内”。 62．句意：20世纪90年代，羊毛贸易快速发展，许多偷猎者为获取皮毛猎杀藏羚羊。根据空后的“rapid development of the wool trade”可知，此处特指羊毛贸易的快速发展，需用定冠词表特指。 63．句意：结果，藏羚羊数量锐减，该物种被列为濒危物种。根据空后的“that the species was listed as endangered”可知，此处是“so…that…”固定句型，表示“如此……以至于……”，说明数量下降得如此之低以至于被列为濒危物种。 64．句意：在过去30年间，中国各类组织一直致力于保护这片脆弱的生态系统。根据空前的形容词“Chinese”以及空后的谓语动词“have been working”可知，此处需填入可数名词复数作主语。organise的名词形式为organisation，其复数为organisations。 65．句意：严苛法规禁止偷猎，阻止工业活动破坏藏羚羊栖息地。根据空后的名词“activities”可知，此处需用形容词作定语修饰名词，表示“工业活动”。industry对应的形容词为industrial。 66．句意：此外，越来越多当地居民加入志愿队伍，协助监测藏羚羊种群数量。根据空前的动词“help”可知，此处是固定搭配help (to) do sth.，表示“帮助做某事”，需用动词原形或动词不定式。 67．句意：保护工作成效显著：藏羚羊数量从1995年不足7万只增长至2024年30万只以上。根据前句“The protection efforts have achieved great success”可知，此处是在具体说明取得的成功，数量增长这一动作从1995年一直持续到现在的2024年，且对现在造成了积极影响，应用现在完成时。主语“the number of Tibetan antelopes”表示“藏羚羊的数量”，谓语动词需用单数形式。 68．句意：这个事例告诉我们：人类活动对自然既能产生负面影响，也能带来积极影响。根据空前的“both negative and positive”可知，人类活动对自然的影响既有消极的也有积极的，影响不止一个，需用可数名词复数形式。 69．句意：当我们在发展与保护之间维持良好平衡，就能与野生动物和谐共处。根据空前的介词“between”以及并列连词“and”可知，此处需与前文的名词“development”保持词性一致，作介词的宾语。protect的名词形式为protection。 70．句意：这段经历凸显出为子孙后代保护自然环境的重要意义。根据主语“This experience”为第三人称单数，且整句陈述的是一个客观结论，应用一般现在时，谓语动词需加-s。 八、任务型阅读（本大题共5题，每题1分，共5分） Rivers are one of our most important natural resources. Many of the world’s great cities are next to rivers, and almost every country has at least one river flowing (流过) through. That plays an important part in the lives of its people. Most rivers begin in mountains and end in oceans. Since the beginning of history, people have used rivers for transportation. The longest one in the US is the Mississippi. The lifeline of Egypt is the Nile. To the people of India, the Ganges is great. Ships can travel along it for a thousand miles. The greatest of all for navigation (航海), is the Amazon in Brazil. It is so wide and so deep that large ships can go about two thousand miles upon it. Besides transportation, rivers give food to eat, water to drink and water for crops (庄稼). In order to increase the supply of water for crops, engineers sometimes build a dam (大坝) across a river. Then people can use the water not only to irrigate (灌溉) their fields but also to make electricity for their homes and industries. However, large cities and industries that are next to rivers often have problems. As the cities grow in size and industries increase in number, the water in the rivers becomes polluted. People have realized the importance of protecting the rivers. They are doing more to keep their rivers clean. 71．What plays an important part in the lives of the people from the text? 72．How long have people used water for transportation? 73．Why is Amazon regarded as the greatest for navigation? 74．What do people use the water from the dam to do? 75．What do you think of protecting water resources? What will you do for it? 【答案】71．The river. 72．Since the beginning of history. 73．It is so wide and so deep that large ships can go about two thousand miles upon it. 74．Not only to irrigate their fields but also to make electricity for their homes and industries. 75．It’s important/necessary. I will ask people not to pollute the water. 【导语】本文是一篇说明文，介绍了河流属于重要自然资源，阐述河流在航运、生活生产方面的实用价值，点明河水污染现状，呼吁大众做好水资源保护工作。 【详解】71．原文首段末尾“Many of the world’s great cities are next to rivers, ... That plays an important part in the lives of its people.”，代词That指代前文的河流，直接点明河流在人们的生活中起到重要作用。 72．原文第二段第二句“Since the beginning of history, people have used rivers for transportation.”，直接点明从人类历史开端起，人们就依托河流开展水上运输。 73．原文第二段末尾“It is so wide and so deep that large ships can go about two thousand miles upon it.”，直接点明亚马孙河通航能力顶尖的原因。 74．原文第三段“Then people can use the water not only to irrigate their fields but also to make electricity for their homes and industries.”，直接说明大坝蓄水的两类用途，提取对应内容即可得出答案。 75．本题为主观开放题，结合文末河流被污染、人们着手护河的内容，先给出对护水的看法，再补充个人可落实的节水护河举措即可。 九、书面表达（本题10分） 请根据以下提示，写一篇关于生态保护成功案例的英文短文。 提示内容： 1. 你选择的动物或植物是什么？ 2. 它们过去面临什么问题和威胁？ 3. 人类活动对它们产生了什么影响？ 4. 现在它们的状况如何？ 5. 它们是如何得到保护的？ 6. 我们能从这个成功案例中学到什么？ 要求： 1. 词数不少于80词； 2. 结构清晰，包含所有要点； 3. 使用本单元所学的词汇和表达（如：endangered species，make great efforts，protected area，habitat，survival等）。 ____________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ 【答案】例文：      The Tibetan antelope is a success story in wildlife protection. In the 1990s, it became an endangered species. Illegal hunting destroyed its habitat and threatened its survival. Its population dropped from over 1 million to fewer than 75,000.      To save it, the Chinese government made great efforts. Strict laws were made and protected areas including Kekexili National Nature Reserve were built. Patrol teams protected the antelopes from poachers.      As a result, its population has recovered to over 300,000. This success shows that with determination and hard work, we can protect endangered species. 【详解】写作步骤 [第一步：审题立意] 确定文体：说明文，以一般过去时和一般现在时为主 明确要点：必须覆盖题干给出的6项提示内容，同时满足词数≥80、使用指定核心词汇的要求 确定人称：以第三人称为主客观介绍案例，结尾阐述启示部分可适当使用第一人称we增强共情 注意事项：选用词汇endangered species、make great efforts、protected area、habitat、survival，自然融入行文，逻辑连贯无要点遗漏 [第二步：构思布局] 三段式结构： 开头段：开门见山引出藏羚羊这个经典生态保护成功案例，阐明过去面临什么问题和威胁，人类活动产生的影响 主体段：保护措施 结尾段：现状以及该案例带来的生态保护启示 [第三步：要点展开] 要点一：选择的保护物种 动物：Tibetan antelope/giant panda等 面临问题：an endangered species/population dropped from over 1 million to fewer than 75,000/on the edge of extinction/natural habitat was broken into small pieces/short of food等 人类活动：illegal hunting/farming and road building/cut down lots of bamboo等 要点二：保护措施 保护行动：government made great efforts/Strict laws were made and protected areas including Kekexili National Nature Reserve were built./Patrol teams protected the antelopes from poachers./government took various measures/introduced strict laws to ban hunting and created the Kekexili National Nature Reserve/set up many protected areas等 要点三：现状 具体描述：As a result, its population has recovered to over 300,000./As a result of these efforts, the Tibetan antelope population has recovered to over 300,000 today./They are no longer critically endangered./Now the panda population is growing, and they are no longer in immediate danger等 要点四：感悟 启示：This success shows that with determination and hard work, we can protect endangered species./It also reminds us that we must never give up our responsibility to protect ecosystems and their wildlife./From this successful case, we learn that if we take proper action, we can get along well with wild animals.等 试卷第2页，共20页 试卷第5页，共20页 学科网（北京）股份有限公司 $
