But now, it's in danger. Every year, thousands of square kilometers of the rainforest are cut down for wood and farmland. This is called deforestation. Deforestation is bad for the earth in many ways. First, it reduces the amount of oxygen. Without enough oxygen, animals and humans will have trouble breathing. Second, many animals and plants live in the Amazon Rainforest. When trees are cut down, their homes are destroyed. Some species even become extinct. Third, deforestation causes climate change. Trees absorb carbon dioxide, a gas that makes the earth warmer. When trees are cut down, more carbon dioxide stays in the air, making the earth hotter. What can we do to stop deforestation? Governments can make laws to limit tree-cutting. Companies can use recycled paper instead of new paper made from trees. We can also help by reducing our use of paper—for example, by using both sides of a piece of paper and saving digital documents instead of printing them. Remember: the Amazon Rainforest is important for all of us. Protecting it is protecting our own home—the earth. 31.Why is the Amazon Rainforest called the “lungs of the earth”? A. Because it has many trees. B. Because it produces 20% of the world's oxygen. C. Because it is very large. D. Because many animals live there. 32.What is deforestation? A. Planting more trees in the rainforest. B. Cutting down trees for wood and farmland. C. Protecting the rainforest. D. Using recycled paper. 33.How many bad effects of deforestation are mentioned in the passage? A. Two. B. Three. C. Four. D. Five. 34.What can companies do to stop deforestation? A. Make laws to limit tree-cutting. B. Cut down more trees for wood. C. Use recycled paper instead of new paper. D. Print more digital documents. 35.What is the main idea of the passage? A. The Amazon Rainforest is in danger, and we need to protect it. B. Deforestation is good for farmland. C. The Amazon Rainforest has many animals. D. We should use more paper in daily life. 【答案】31.B 32.B 33.B 34.C 35.A 【导语】本文以 “地球之肺 —— 亚马逊雨林” 为切入点，介绍森林砍伐（滥伐）的危害及应对措施，强调 “保护雨林即保护地球”，贴合单元 “地球保护” 的核心主题。 【详解】 31. 细节理解题。根据第一段 “The Amazon Rainforest is called the ‘lungs of the earth’ because it produces 20% of the world's oxygen” 可知，亚马逊雨林被称为 “地球之肺” 是因为 “它产生了全球 20% 的氧气”，故选 B。 32. 细节理解题。根据第一段 “Every year, thousands of square kilometers of the rainforest are cut down for wood and farmland. This is called deforestation” 可知，“滥伐” 指 “为获取木材和农田而砍伐树木”，故选 B。 33. 细节理解题。根据第二段 “First, it reduces the amount of oxygen... Second, many animals and plants... Third, deforestation causes climate change” 可知，文中提到了滥伐的 “三个危害”，故选 B。 34. 细节理解题。根据第三段 “Companies can use recycled paper instead of new paper made from trees” 可知，企业可通过 “使用再生纸而非树木制成的新纸” 阻止滥伐，故选 C。 35. 主旨大意题。全文围绕 “亚马逊雨林面临滥伐危险” 展开，先介绍危害，再给出保护措施，最后总结 “保护雨林即保护地球”，核心是 “亚马逊雨林濒危，我们需保护它”，故选 A。 (B) Water is one of the most important resources on earth. Without water, no living things can survive. But now, many places in the world are facing water shortage. This is because of pollution and waste. Industrial waste is a big cause of water pollution. Factories pour dirty water into rivers and lakes, making the water unsafe to drink. Agricultural activities also pollute water—farmers use chemicals that flow into rivers when it rains. In daily life, people waste a lot of water. For example, some people leave the tap running while brushing their teeth, and others take long showers. To solve water shortage, we need to reduce pollution and save water. Governments can punish factories that pour dirty water into rivers. Farmers can use fewer chemicals. We can save water by turning off the tap when brushing teeth, taking shorter showers, and reusing water—for example, using water from washing vegetables to water plants. Water is precious. We must save it for ourselves and future generations. 36.Why is water important? A. Because it is cheap. B. Because no living things can survive without it. C. Because it is easy to get. D. Because it is clean. 37.What causes water shortage? A. Pollution and waste. B. Too much rain. C. Too many rivers. D. More factories. 38.Which of the following is a cause of water pollution? A. Using water to water plants. B. Taking short showers. C. Factories pouring dirty water into rivers. D. Turning off the tap when brushing teeth. 39.How can we save water in daily life? A. Take long showers. B. Leave the tap running while brushing teeth. C. Reuse water from washing vegetables. D. Use more chemicals. 40.What is the main idea of the passage? A. Water is precious, and we need to reduce pollution and save water. B. Water pollution is not a big problem. C. We can waste water in daily life. D. Factories can pour dirty water into rivers. 【答案】36.B 37.A 38.C 39.C 40.A 【导语】本文介绍 “水资源的重要性、短缺原因（污染与浪费）及节约措施”，强调 “水资源珍贵，需护水节水”，与单元 “地球资源保护” 的主题高度契合。 【详解】 36. 细节理解题。根据第一段 “Without water, no living things can survive” 可知，水重要是因为 “没有水，任何生物都无法生存”，故选 B。 37. 细节理解题。根据第一段 “But now, many places in the world are facing water shortage. This is because of pollution and waste” 可知，水资源短缺的原因是 “污染与浪费”，故选 A。 38. 细节理解题。根据第二段 “Industrial waste is a big cause of water pollution. Factories pour dirty water into rivers and lakes” 可知，“工厂向河流排放污水” 是水污染的原因之一，故选 C。 39. 细节理解题。根据第三段 “We can save water by... reusing water—for example, using water from washing vegetables to water plants” 可知，“用洗菜水浇花” 是日常节水的方法，故选 C。 40. 主旨大意题。全文先讲 “水的重要性与短缺问题”，再分析原因，最后给出 “减污染、节水” 的措施，核心是 “水很珍贵，我们需减污染、节水”，故选 A。 六、句型转换（共 5 小题，每小题 2 分，共 10 分） 按下面各题要求完成句型转换，每空一词。 41.We should plant more trees to protect the earth.（对划线部分提问） _______ _______ we _______ to protect the earth? 【答案】What should; do 【详解】考查对 “行动措施” 的提问。原句意为 “我们应该多种树来保护地球”，划线部分 “plant more trees” 是 “保护地球的具体行动”，用 “What” 提问；情态动词 “should” 提到主语前，后接动词原形 “do”。故填 What should; do。 42.The river was clean before.（改为否定句） The river _______ _______ clean before. 【答案】was not /wasn't 【详解】考查一般过去时的否定句。原句意为 “这条河以前很干净”，时态是一般过去时，变否定句在 be 动词 “was” 后加 “not”，缩写为 “wasn't”。故填 was not /wasn't。 43.People cut down too many trees every year.（改为被动语态） Too many trees _______ _______ down by people every year. 【答案】are cut 【详解】考查一般现在时的被动语态。原句意为 “人们每年砍伐太多树木”，被动语态结构为 “be + 过去分词”；主语 “too many trees” 是复数，时态是一般现在时，be 动词用 “are”，“cut” 的过去分词是 “cut”。故填 are cut。 44.We have protected the environment for five years.（对划线部分提问） _______ _______ have we protected the environment? 【答案】How long 【详解】考查对 “时间长度” 的提问。原句意为 “我们已经保护环境五年了”，划线部分 “for five years” 是时间长度，用 “How long”（多久）提问。故填 How long。 45.We can save water by turning off the tap when brushing teeth.（对划线部分提问） _______ _______ we _______ water? 【答案】How can; save 【详解】考查对 “方式” 的提问。原句意为 “我们可以通过刷牙时关水龙头来节水”，划线部分 “by turning off the tap when brushing teeth” 是 “节水的方式”，用 “How” 提问；情态动词 “can” 提到主语前，后接动词原形 “save”。故填 How can; save。 七、书面表达（共 10 分） 1.假设你是李华，你的笔友 Peter 来信询问你所在城市的水资源情况及你们家的节水措施。请你根据以下提示给 Peter 回一封电子邮件。 提示： 2.城市水资源情况：部分河流曾因污染变脏，现在政府已采取措施治理，水质有所改善，但仍需节约； 3.家庭节水措施：刷牙时关水龙头、用洗菜水浇花、缩短淋浴时间； 4.呼吁：水资源珍贵，大家应共同节水。 要求： 5.词数 60-80 左右； 6.条理清晰，语句通顺，语法正确； 7.包含所有提示信息，可适当发挥。 _______________________________________________________________________________ _______________________________________________________________________________ _______________________________________________________________________________ _______________________________________________________________________________ _______________________________________________________________________________ 【范文】 Dear Peter, I'm glad to receive your email. You asked about our city's water and our family's water-saving ways. Some rivers here were dirty due to pollution before, but the government has cleaned them up—water quality is better now. However, we still need to save water. My family does this by turning off the tap while brushing teeth, reusing vegetable water to water flowers, and taking shorter showers. Water is precious. Let's save it together! What about your city? Yours, Li Hua 【导语】本篇书面表达属于应用文（电子邮件）。文章以李华的视角，结合 “城市水资源治理” 和 “家庭节水措施”，向笔友 Peter 传递 “水资源珍贵、需共同节约” 的观点，完全贴合单元 “地球资源保护” 的核心主题。 【详解】 1.词汇积累 水质改善：water quality is better→ water quality has improved a lot（水质改善了很多，补充 “has improved a lot”，强化 “改善” 的程度，更具体） 关水龙头：turn off the tap→ turn off the tap while brushing teeth（刷牙时关水龙头，补充 “while brushing teeth”，明确场景，使措施更清晰） 用洗菜水浇花：reuse vegetable water to water flowers→ reuse water from washing vegetables to water flowers（用洗菜的水浇花，补充 “from washing”，表述更准确） 水资源珍贵：Water is precious→ Water is a precious resource（水是珍贵的资源，补充 “a precious resource”，强调 “资源属性”，贴合单元 “地球资源” 主题） 2.句式拓展 （1）简单句变复合句 原句：Some rivers were dirty. The government cleaned them up. 拓展句：Some rivers here were dirty due to pollution before, but the government has taken measures to clean them up. （用 “but” 转折连接 “污染” 与 “治理”，补充 “due to pollution”“taken measures”，使逻辑更连贯，体现 “问题与解决” 的过程） （2）简单句变并列句 原句：We turn off the tap. We reuse water. 拓展句：My family saves water by turning off the tap while brushing teeth and reusing vegetable water to water flowers. （用 “and” 连接两个节水措施，用 “by” 统一 “方式”，使句子更简洁，突出 “家庭节水的具体做法”） （3）调整语序增强呼吁 原句：We should save water together. 拓展句：Water is a precious resource for everyone, so we should work together to save it. （用 “so” 连接 “水资源珍贵” 与 “共同节水”，补充 “for everyone”，强化 “人人有责” 的意识，呼吁更有说服力） 【点睛】 【高分句型 1】 Some rivers here were dirty due to pollution before, but the government has cleaned them up—water quality is better now. （可优化为：Some rivers in our city were once polluted and became dirty, but the government has taken effective measures to treat them, so water quality has improved a lot recently.） （补充 “once”“effective measures”“treat them”，细化 “污染与治理” 的细节，使描述更生动，体现 “政府的积极行动”） 【高分句型 2】 My family does this by turning off the tap while brushing teeth, reusing vegetable water to water flowers, and taking shorter showers. （可优化为：To save water, my family has formed good habits—we turn off the tap while brushing teeth, reuse water from washing vegetables to water our garden, and keep our showers short.） （用 “To save water” 明确目的，用 “formed good habits” 强调 “习惯养成”，补充 “our garden”，使场景更具体，突出 “家庭节水的主动性”） 原创精品资源学科网独家享有版权，侵权必究！ 学科网（北京）股份有限公司 学科网（北京）股份有限公司 $ 编写说明：本套《同步单元AB卷》紧扣《英语 基础模块1》（外研版）教材，以教材单元为基准精准覆盖核心考点，并紧密贴合职教高考真题题型。A卷为考点梳理卷，侧重考点分层突破；B卷为单元测试卷，强化综合能力检测，助力师生高效把握教学重点，提升应试能力与知识应用水平。 本卷是Unit 5 We Have Only One Earth!的单元测试卷，主要考查词汇、词组、句式句型、情景交际功能话题、阅读能力和书面表达能力。 Unit 5 We Have Only One Earth!

But now, it's in danger. Every year, thousands of square kilometers of the rainforest are cut down for wood and farmland. This is called deforestation. Deforestation is bad for the earth in many ways. First, it reduces the amount of oxygen. Without enough oxygen, animals and humans will have trouble breathing. Second, many animals and plants live in the Amazon Rainforest. When trees are cut down, their homes are destroyed. Some species even become extinct. Third, deforestation causes climate change. Trees absorb carbon dioxide, a gas that makes the earth warmer. When trees are cut down, more carbon dioxide stays in the air, making the earth hotter. What can we do to stop deforestation? Governments can make laws to limit tree-cutting. Companies can use recycled paper instead of new paper made from trees. We can also help by reducing our use of paper—for example, by using both sides of a piece of paper and saving digital documents instead of printing them. Remember: the Amazon Rainforest is important for all of us. Protecting it is protecting our own home—the earth. 31.Why is the Amazon Rainforest called the “lungs of the earth”? A. Because it has many trees. B. Because it produces 20% of the world's oxygen. C. Because it is very large. D. Because many animals live there. 32.What is deforestation? A. Planting more trees in the rainforest. B. Cutting down trees for wood and farmland. C. Protecting the rainforest. D. Using recycled paper. 33.How many bad effects of deforestation are mentioned in the passage? A. Two. B. Three. C. Four. D. Five. 34.What can companies do to stop deforestation? A. Make laws to limit tree-cutting. B. Cut down more trees for wood. C. Use recycled paper instead of new paper. D. Print more digital documents. 35.What is the main idea of the passage? A. The Amazon Rainforest is in danger, and we need to protect it. B. Deforestation is good for farmland. C. The Amazon Rainforest has many animals. D. We should use more paper in daily life. (B) Water is one of the most important resources on earth. Without water, no living things can survive. But now, many places in the world are facing water shortage. This is because of pollution and waste. Industrial waste is a big cause of water pollution. Factories pour dirty water into rivers and lakes, making the water unsafe to drink. Agricultural activities also pollute water—farmers use chemicals that flow into rivers when it rains. In daily life, people waste a lot of water. For example, some people leave the tap running while brushing their teeth, and others take long showers. To solve water shortage, we need to reduce pollution and save water. Governments can punish factories that pour dirty water into rivers. Farmers can use fewer chemicals. We can save water by turning off the tap when brushing teeth, taking shorter showers, and reusing water—for example, using water from washing vegetables to water plants. Water is precious. We must save it for ourselves and future generations. 36.Why is water important? A. Because it is cheap. B. Because no living things can survive without it. C. Because it is easy to get. D. Because it is clean. 37.What causes water shortage? A. Pollution and waste. B. Too much rain. C. Too many rivers. D. More factories. 38.Which of the following is a cause of water pollution? A. Using water to water plants. B. Taking short showers. C. Factories pouring dirty water into rivers. D. Turning off the tap when brushing teeth. 39.How can we save water in daily life? A. Take long showers. B. Leave the tap running while brushing teeth. C. Reuse water from washing vegetables. D. Use more chemicals. 40.What is the main idea of the passage? A. Water is precious, and we need to reduce pollution and save water. B. Water pollution is not a big problem. C. We can waste water in daily life. D. Factories can pour dirty water into rivers. 六、句型转换（共 5 小题，每小题 2 分，共 10 分） 按下面各题要求完成句型转换，每空一词。 41.We should plant more trees to protect the earth.（对划线部分提问） _______ _______ we _______ to protect the earth? 42.The river was clean before.（改为否定句） The river _______ _______ clean before. 43.People cut down too many trees every year.（改为被动语态） Too many trees _______ _______ down by people every year. 44.We have protected the environment for five years.（对划线部分提问） _______ _______ have we protected the environment? 45.We can save water by turning off the tap when brushing teeth.（对划线部分提问） _______ _______ we _______ water? 七、书面表达（共 10 分） 1.假设你是李华，你的笔友 Peter 来信询问你所在城市的水资源情况及你们家的节水措施。请你根据以下提示给 Peter 回一封电子邮件。 提示： 2.城市水资源情况：部分河流曾因污染变脏，现在政府已采取措施治理，水质有所改善，但仍需节约； 3.家庭节水措施：刷牙时关水龙头、用洗菜水浇花、缩短淋浴时间； 4.呼吁：水资源珍贵，大家应共同节水。 要求： 5.词数 60-80 左右； 6.条理清晰，语句通顺，语法正确； 7.包含所有提示信息，可适当发挥。 _______________________________________________________________________________ _______________________________________________________________________________ _______________________________________________________________________________ _______________________________________________________________________________ _______________________________________________________________________________ 原创精品资源学科网独家享有版权，侵权必究！ 学科网（北京）股份有限公司 学科网（北京）股份有限公司 $
