At home, we rely on it for cooking,... and cleaning.”可知，这里列举在家用水的用途，“washing”（洗涤；清洗）符合语境，与“cooking”和“cleaning”并列，都是在家用水做的事情。“sleep”（睡觉）和“read”（阅读）不需要用水，所以选C。 9. 答案：B. without 解析：“It's hard to imagine a day without water.” 意思是很难想象没有水的一天。“without”表示“没有”，符合文意，因为水在日常生活中很重要，没有水难以想象。“with”（有；和……一起）、“in”（在……里面）、“on”（在……上面）都不符合语境，所以选B。 10. 答案：A. activities 解析：“Outside, water is used for various industrial activities and for transportation...” 意思是在外面，水被用于各种工业活动和运输。“activities”（活动）符合语境，“industrial activities”表示“工业活动”。“jobs”（工作）、“games”（游戏）、“shows”（演出）都不能准确表达水在工业方面的用途，所以选A。 11. 答案：C. limited 解析：根据“Only about 1% of the water on Earth can be used directly.”可知，地球上只有大约1%的水可以直接使用，所以可利用的淡水数量是“有限的”。“limited”表示“有限的”，符合文意。“many”（许多）、“plenty”（大量的）与原文意思相反；“few”修饰可数名词复数，“water”是不可数名词，所以选C。 12. 答案：B. aware 解析：“We should be aware of this fact and take steps to save water.” 意思是我们应该意识到这个事实并采取措施节约用水。“be aware of...”是固定短语，意为“意识到……”。“afraid”（害怕的）、“sure”（确定的）、“proud”（骄傲的）都不符合语境，所以选B。 13. 答案：B. turn off 解析：根据“For example, we can...the tap while brushing our teeth and collect rainwater for watering plants.”可知，这里是在举例说明节约用水的方法，刷牙时应该“关掉”水龙头。“turn off”表示“关掉”，符合文意。“turn on”（打开）、“turn up”（调高；出现）、“turn down”（调低；拒绝）都不符合节约用水的做法，所以选B。 14. 答案：A. valuable 解析：根据“In deserts, water is even more...”以及“People there have to be extremely careful with every drop.”可知，在沙漠里，人们对每一滴水都非常小心，说明水在沙漠里更加“珍贵”。“valuable”表示“有价值的；珍贵的”，符合语境。“useless”（无用的）、“cheap”（便宜的）、“common”（常见的）都不符合沙漠地区水的情况，所以选A。 15. 答案：B. difference 解析：“We can learn from them and make a difference to save water in our own lives.” 意思是我们可以向他们学习，在我们自己的生活中为节约用水做出改变。“make a difference”是固定短语，意为“有影响；起作用；做出改变”。“make a mistake”（犯错）、“make a face”（做鬼脸）、“make a mess”（弄得一团糟）都不符合文意，所以选B。 第二部分 阅读（共三节, 满分50分） 第一节（共12个小题; 每小题2.5分, 满分30分） 阅读下面三个语篇, 从每题所给的A、B、C三个选项中, 选出各题的最佳选项。 A Water is the source of life. On Earth, water exists in various forms, from the vast oceans to the tiniest droplets in the air. The water cycle keeps water moving around the planet. When the sun heats the water in oceans, rivers, and lakes, it turns into vapor and rises into the air. There, it forms clouds, and when the conditions are right, it falls back to the earth as rain, snow, sleet, or hail. We use water in countless ways. At home, it's essential for cooking, cleaning, and personal hygiene. In industries, water is used for manufacturing, generating electricity, and more. Water is also crucial for agriculture, as crops need it to grow. However, clean water is not always easily accessible. In some regions, especially in deserts or areas with water pollution, people struggle to get enough clean water for daily use. Water pollution, mainly caused by industrial waste, agricultural chemicals, and improper sewage disposal, is a growing concern. It not only affects human health but also harms aquatic ecosystems. 16. What is the main idea of the first paragraph? A. The importance of water in our daily life. B. The forms of water on Earth and the water cycle. C. How water falls back to the earth. D. The sources of water vapor. 17. According to the passage, which is NOT a way we use water? A. For entertainment like swimming. B. For cooking at home. C. For manufacturing in industries. D. For growing crops in agriculture. 18. Why do some regions lack clean water? A. Because there is no water cycle there. B. Because people use too much water for industry. C. Because of the location like deserts or water pollution. D. Because the sun heats the water too much. 19. What can we infer from the passage? A. Water pollution only affects humans. B. We don't need to worry about water shortage. C. The water cycle stops water from being used up. D. Everyone has easy access to clean water. 16. 答案：B 解析：第一段第一句“Water is the source of life. On Earth, water exists in various forms, from the vast oceans to the tiniest droplets in the air.”提到了地球上水存在的各种形式，接着“The water cycle keeps water moving around the planet. When the sun heats the water in oceans, rivers, and lakes, it turns into vapor and rises into the air. There, it forms clouds, and when the conditions are right, it falls back to the earth as rain, snow, sleet, or hail.”详细介绍了水循环的过程。A选项“水在我们日常生活中的重要性”是第二段的内容；C选项“水如何回到地球”只是水循环的一部分；D选项“水蒸气的来源”也只是水循环中的一个环节。所以第一段的主要内容是地球上水的形式和水循环，B选项正确。 17. 答案：A 解析：根据文章第二段“At home, it's essential for cooking, cleaning, and personal hygiene. In industries, water is used for manufacturing, generating electricity, and more. Water is also crucial for agriculture, as crops need it to grow.”可知，水用于家庭烹饪、工业制造、农业种植等。B选项“在家做饭”、C选项“工业制造”、D选项“农业种植庄稼”都在文中提到了。而A选项“用于像游泳这样的娱乐活动”在文中未提及，所以选A。 18. 答案：C 解析：由第三段“In some regions, especially in deserts or areas with water pollution, people struggle to get enough clean water for daily use.”可知，一些地区缺乏干净的水是因为处于沙漠地区或者存在水污染问题。A选项“因为那里没有水循环”与原文不符，水循环是全球都存在的；B选项“因为人们在工业上用水太多”文中未提及是缺乏干净水的原因；D选项“因为太阳过度加热水”也不是缺乏干净水的原因。所以C选项正确。 19. 答案：C 解析：A选项“水污染只影响人类”，根据第三段“It not only affects human health but also harms aquatic ecosystems.”可知水污染不仅影响人类还危害水生生态系统，A错误；B选项“我们不需要担心水资源短缺”，从第三段可知一些地区缺乏干净的水，所以我们需要担心水资源短缺问题，B错误；C选项“水循环阻止水被用光”，根据第一段“The water cycle keeps water moving around the planet.”可知水循环使水在地球上不断循环，能够阻止水被用光，C正确；D选项“每个人都能容易地获得干净的水”，由第三段可知一些地区的人们很难获得足够的干净水用于日常使用，D错误。所以选C。 B Deserts are areas where water is scarce. People living in deserts have to adapt to this harsh environment. A family in the desert may take a shower only once a week to save water. After showering, they reuse the water for other purposes, like cleaning the floor or watering plants. Most of the water in deserts comes from underground. But digging wells to get water is expensive, and the amount of water available is limited. So, people have to make every drop count. They seldom plant flowers or grass because these need a lot of water. Despite the difficulties, people in deserts have learned to live with limited water resources. They have developed ways to conserve and reuse water. We can learn from their experience and apply these water - saving methods in our daily lives, no matter where we live. 20. Why do people in deserts take a shower only once a week? A. Because they don't like showering. B. Because water is very scarce in deserts. C. Because they are too busy. D. Because the water is too dirty. 21. Where does most of the water in deserts come from? A. From the rain. B. From the rivers flowing through. C. From underground. D. From the nearby lakes. 22. What does the underlined phrase “make every drop count” mean? A. To count the number of water drops. B. To make water more expensive. C. To use water carefully and not waste it. D. To make water clean. 23. What is the main purpose of this passage? A. To describe the life in deserts. B. To show how people in deserts get water. C. To tell us the importance of water in deserts. D. To encourage us to learn water - saving methods from desert people. 20. 答案：B 解析：根据文章第一段“Deserts are areas where water is scarce. People living in deserts have to adapt to this harsh environment. A family in the desert may take a shower only once a week to save water.”可知，沙漠地区水资源稀缺，人们为了节约用水，一个家庭可能一周只洗一次澡。A选项“因为他们不喜欢洗澡”、C选项“因为他们太忙了”、D选项“因为水太脏了”在文中均未提及，而B选项“因为沙漠里水非常稀缺”符合文意，所以选B。 21. 答案：C 解析：由文章第二段“Most of the water in deserts comes from underground.”可知，沙漠里的大部分水来自地下。A选项“来自雨水”、B选项“来自流经的河流”、D选项“来自附近的湖泊”在文中都没有提到沙漠里的水来自这些地方，所以C选项“来自地下”正确。 22. 答案：C 解析：前文提到沙漠地区水资源稀缺，打井取水昂贵且可用水量有限，所以人们必须“make every drop count”，结合语境可知其意思是要小心用水，不浪费每一滴水。A选项“数水滴的数量”、B选项“让水更贵”、D选项“让水变干净”都不符合文意，C选项“小心用水且不浪费水”正确，所以选C。 23. 答案：D 解析：文章先描述了沙漠地区水资源稀缺的情况以及人们节约用水的方式，如一周洗一次澡、重复利用洗澡水等，最后一段提到“We can learn from their experience and apply these water - saving methods in our daily lives, no matter where we live.”，即我们可以从沙漠地区人们的经验中学习，并在日常生活中应用这些节水方法。A选项“描述沙漠中的生活”只是文章的部分内容；B选项“展示沙漠里的人们如何获取水”也只是其中一个方面；C选项“告诉我们水在沙漠中的重要性”也不全面。文章的主要目的是鼓励我们学习沙漠地区人们的节水方法，D选项正确。 C World Water Day, celebrated on March 22nd, aims to raise awareness about the importance of freshwater and advocate for the sustainable management of water resources. On this day, various activities are held around the world. Schools often organize educational programs to teach students about water conservation. Communities may hold exhibitions or clean - up events near water bodies. People also use social media to spread the message of saving water. We all need water, but the earth's water resources are under threat. By celebrating World Water Day, we can encourage more people to take action to protect water. Simple things like turning off the tap when brushing teeth, collecting rainwater, and reusing water can make a big difference. 24. When is World Water Day celebrated? A. On March 12th. B. On March 22nd. C. On April 22nd. D. On May 22nd. 25. Which of the following activities is NOT mentioned on World Water Day? A. Educational programs in schools. B. Sports competitions. C.

A. Keep the tap running while brushing teeth. B. Throw away drinking water bottles with water left. C. Collect rainwater and reuse water. D. Take long showers. 24. 答案：B 解析：根据文章第一句“World Water Day, celebrated on March 22nd...”可知，世界水日是在3月22日庆祝，所以B选项正确。 25. 答案：B 解析：文章第二段提到“Schools often organize educational programs to teach students about water conservation. Communities may hold exhibitions or clean - up events near water bodies.”，分别对应A选项“学校的教育项目”、C选项“社区的展览”、D选项“水体附近的清理活动”，而B选项“体育比赛”在文中未提及，所以选B。 26. 答案：B 解析：从文章第一句“World Water Day, celebrated on March 22nd, aims to raise awareness about the importance of freshwater and advocate for the sustainable management of water resources.”以及第三段“By celebrating World Water Day, we can encourage more people to take action to protect water.”可知，庆祝世界水日是为了提高人们对淡水重要性的认识并倡导保护水资源，B选项正确。A选项“为了举办派对”、C选项“为了使用更多的水”、D选项“为了炫耀我们关于水的知识”均不符合文意。 27. 答案：C 解析：文章第三段提到“Simple things like turning off the tap when brushing teeth, collecting rainwater, and reusing water can make a big difference.”，A选项“刷牙时让水龙头一直开着”、B选项“扔掉还有水的饮用水瓶”、D选项“长时间淋浴”都是浪费水的行为，不符合保护水的做法；C选项“收集雨水和重复用水”符合文中提到的保护水的方法，所以选C。 第二节（共5个小题;每小题2分,满分10分） 根据短文内容，从6个选项中选出能分别填入5个小题空白处的最佳选项。 Water is a precious resource on our planet. 28.______.

Let's all play a part in 52.______ (keep) our water clean and available for future generations. 43. 答案：important 解析：“one of the + 形容词最高级 + 名词复数”是固定结构，“resources”是名词，前面需要用形容词修饰，“importance”是名词，其形容词形式是“important”，“one of the most important resources”表示“最重要的资源之一”，所以填“important”。 44. 答案：moving 解析：“keep sb./sth. doing sth.”是固定用法，意为“使某人/某物一直做某事”，“The water cycle is a continuous process that keeps water moving around the planet.” 意思是水循环是一个让水一直在地球上循环的持续过程，“water”和“move”之间是主动关系，所以用现在分词“moving”，故填“moving”。 45. 答案：as 解析：“When the clouds are heavy enough, water falls back to the earth as rain, snow, or other forms.” 这里“as”是介词，意为“作为”，表示水以雨、雪或其他形式降落到地球上，所以填“as”。 46. 答案：purposes 解析：“many”后接可数名词复数，“purpose”是可数名词，“We use water in our daily lives for many purposes”表示“我们在日常生活中用水有很多用途”，所以“purpose”要用复数形式“purposes”，故填“purposes”。 47. 答案：mainly 解析：“Some regions are facing water shortages mainly because of pollution and over - use.” 这里“because of pollution and over - use”是原因状语，需要用副词来修饰整个原因状语，“main”是形容词，其副词形式是“mainly”，表示“主要地”，所以填“mainly”。 48. 答案：to protect 解析：“take action to do sth.”是固定短语，意为“采取行动做某事”，“To solve this problem, we should take action to protect water resources.” 即“为了解决这个问题，我们应该采取行动保护水资源”，所以用动词不定式“to protect”，故填“to protect”。 49. 答案：using 解析：“when not using it”是“when we are not using it”的省略形式，“we”和“use”之间是主动关系，所以用现在分词形式，“such as turning off the tap when not using it” 表示“比如当不用水的时候关掉水龙头”，故填“using”。 50. 答案：handling 解析：“by”是介词，意为“通过”，介词后面接动词的 -ing 形式，“handle”的 -ing 形式是“handling”，“Also, we should prevent water pollution by properly handling waste.” 表示“我们也应该通过妥善处理废物来防止水污染”，所以填“handling”。 51. 答案：to ensure 解析：“do everything we can to do sth.”是固定结构，意为“尽我们所能做某事”，“In a word, water is vital to our lives, and we must do everything we can to ensure its sustainable use.” 意思是“总之，水对我们的生活至关重要，我们必须尽我们所能确保它的可持续利用”，所以用动词不定式“to ensure”，故填“to ensure”。 52. 答案：keeping 解析：“play a part in doing sth.”是固定短语，意为“在做某事方面起作用”，“Let's all play a part in keeping our water clean and available for future generations.” 表示“让我们都在保持我们的水清洁并为子孙后代提供可用的水方面发挥作用”，所以“keep”要用 -ing 形式“keeping”，故填“keeping”。 第四部分 写作（满分25分） 53. 结合关于水资源的信息，以及沙漠地区节水的内容，写一篇短文阐述节约用水的重要性，并给出一些在日常生活中可行的节水措施，字数120 - 150 词________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ The Importance of Water Conservation Water is a precious resource. As shown in the materials, although the earth seems full of water, we can only use about 1% of it. In deserts, water scarcity makes people's lives extremely tough. They take quick showers once a week and reuse water, which shows how valuable water is. In our daily lives, we should also take action to save water. For example, turn off the tap when brushing teeth or washing hands. We can collect rainwater for watering plants. When doing laundry, wait until we have a full load. Saving water not only helps those in water - scarce areas but also ensures a sustainable future for the entire planet. 1 / 14 学科网（北京）股份有限公司 $$ Unit 8 Our Blue Planet 单元卷·测试卷 注意事项： 1. 全卷共四个部分, 满分120分, 考试时间为100分钟, 考试形式为闭卷。 2. 请在答题卡指定位置作答, 在试题卷上答题视为无效。 3. 选择题均为单项选择, 多选不得分。 第一部分 完形（共两节，满分20分） 第一节（共5个小题; 每小题1分, 满分5分） 阅读下面短文，从框内6个选项中选出能分别填入5个小题空白处的最佳选项。 A. goes up B. clean C. save D. moves E. gets F. looks Water is one of the most important resources on the earth.

On Earth, water exists in various forms, from the vast oceans to the tiniest droplets in the air. The water cycle keeps water moving around the planet. When the sun heats the water in oceans, rivers, and lakes, it turns into vapor and rises into the air. There, it forms clouds, and when the conditions are right, it falls back to the earth as rain, snow, sleet, or hail. We use water in countless ways. At home, it's essential for cooking, cleaning, and personal hygiene. In industries, water is used for manufacturing, generating electricity, and more. Water is also crucial for agriculture, as crops need it to grow. However, clean water is not always easily accessible. In some regions, especially in deserts or areas with water pollution, people struggle to get enough clean water for daily use. Water pollution, mainly caused by industrial waste, agricultural chemicals, and improper sewage disposal, is a growing concern. It not only affects human health but also harms aquatic ecosystems. 16. What is the main idea of the first paragraph? A. The importance of water in our daily life. B. The forms of water on Earth and the water cycle. C. How water falls back to the earth. D.

We don't need to worry about water shortage. C. The water cycle stops water from being used up. D. Everyone has easy access to clean water. B Deserts are areas where water is scarce. People living in deserts have to adapt to this harsh environment. A family in the desert may take a shower only once a week to save water. After showering, they reuse the water for other purposes, like cleaning the floor or watering plants. Most of the water in deserts comes from underground. But digging wells to get water is expensive, and the amount of water available is limited. So, people have to make every drop count. They seldom plant flowers or grass because these need a lot of water. Despite the difficulties, people in deserts have learned to live with limited water resources. They have developed ways to conserve and reuse water. We can learn from their experience and apply these water - saving methods in our daily lives, no matter where we live. 20. Why do people in deserts take a shower only once a week? A. Because they don't like showering. B. Because water is very scarce in deserts. C. Because they are too busy. D. Because the water is too dirty. 21. Where does most of the water in deserts come from? A. From the rain. B. From the rivers flowing through. C. From underground. D. From the nearby lakes. 22. What does the underlined phrase “make every drop count” mean? A. To count the number of water drops. B. To make water more expensive. C. To use water carefully and not waste it. D. To make water clean. 23. What is the main purpose of this passage? A. To describe the life in deserts. B. To show how people in deserts get water. C. To tell us the importance of water in deserts. D. To encourage us to learn water - saving methods from desert people. C World Water Day, celebrated on March 22nd, aims to raise awareness about the importance of freshwater and advocate for the sustainable management of water resources. On this day, various activities are held around the world. Schools often organize educational programs to teach students about water conservation. Communities may hold exhibitions or clean - up events near water bodies. People also use social media to spread the message of saving water. We all need water, but the earth's water resources are under threat. By celebrating World Water Day, we can encourage more people to take action to protect water. Simple things like turning off the tap when brushing teeth, collecting rainwater, and reusing water can make a big difference. 24. When is World Water Day celebrated? A. On March 12th. B.
