Only 1% of the Earth’s water is safe to drink. Teachers show videos about dry places where people walk far to get water. They teach easy ways to save water: ● Turn off taps when brushing teeth (this saves 8 liters a day!). ● Fix broken pipes quickly. Students make posters with words like “Save Water!” and draw pictures of reusing washing water for plants. They also play a game to guess how much water daily activities use. For example, a 10-minute shower uses 100 liters! The winner gets a special water bottle. Now, students always check taps at home. 26.How much water can we drink on Earth?

A school water-saving activity B. How to drink water C. Fun games for children D. Life in dry places B The water cycle is very important for life on Earth. Let me tell you how it works. First, the sun shines on rivers, lakes and oceans. The heat makes water warm and go up into the air as very small drops. This is called evaporation. When these water drops go high into the sky, they get cold and come together to make clouds. This part is called condensation. Then, when the clouds become too heavy, the water falls back to the ground as rain or snow. We call this precipitation. The rainwater runs into rivers and lakes again, and some goes deep into the ground. Finally, the sun warms the water again, and the cycle starts over. This cycle gives us clean water to drink, so we must keep our rivers and oceans clean. 31.What makes water go up into the air? A. Wind B. Rain C. Sunlight D. Snow 32.What do we call the process of cloud formation? A. Evaporation B. Condensation C. Precipitation D. Collection 33.Why must we keep rivers clean? A. To make boats faster B. To have clean drinking water C. To help fish fly D. To stop the water cycle 34.What is the correct order of the water cycle? a. Rain falls b. Sun heats water c . Clouds form d. Water goes to rivers A. b→c→a→d B. c→b→a→d C. a→d→b→c D. d→a→b→c 35.What's the main idea of the text? A. How to make rain B. Why the sun is hot C. How nature reuses water D. Different kinds of clouds C Imagine this: Your alarm rings at 7 AM, but when you turn on the tap – no water! You can't brush your teeth or wash your face. Your hands stay sticky all day. At breakfast, there's no milk because cows need water too. You eat dry bread with jam. At school, the toilets smell bad because they can't flush. After running in P.E. class, your mouth feels like sand, but the water fountain is empty. At lunch, there's only cold sandwiches – no soup or juice. When you get home, the plants in the yard are dying. Mom says, "We can't wash vegetables or cook rice tonight." You use wet tissues to clean your hands. Before bed, you think: Water is more important than I ever knew! 36.Why can't you have milk for breakfast? A. No refrigerator B. Cows need water C. The shop is closed D.

We use water to drink, __16__ vegetables and wash clothes. However, many people __17__water.

Usually C. Never D. Sometimes 25.A. for B. about C. to D. with 16.【答案】A 【解析】本句中“to drink”“cook vegetables”“wash clothes”是并列结构，都用动词原形，共同作目的状语。句意是我们用水来喝、煮蔬菜和洗衣服。这里需要动词原形，而不是动名词形式“cooking”，也不是第三人称单数形式“cooks”，“to cook”在结构上不符合并列要求。故选A。 17.【答案】B 【解析】根据后面提到要节约用水的提示可知，前面说的是很多人浪费水。“save”是节约；“collect”是收集；“reuse”是再利用，均不符合语境。“waste”表示浪费，符合前后文逻辑。句意是然而，很多人浪费水。故选B。 18.【答案】B 【解析】根据常识，刷牙时不应该让水一直流，这是一个祈使句的否定形式，祈使句的否定通常是在动词原形前加“Don't”。“Keep”是肯定形式；“Keeping”是动名词形式；“Not keep”结构错误。句意是刷牙时不要让水一直流。故选B。 19.【答案】B 【解析】为了节约用水，应该洗快速的淋浴而不是泡澡。“long”长的；“slow”慢的；“warm”温暖的，都不利于节约用水。“quick”快速的，洗快速淋浴能节约用水。句意是洗快速淋浴，而不是泡澡。故选B。 20.【答案】B 【解析】“empty”空的；“dirty”脏的；“clean”干净的，根据“with water inside”可知瓶子里是有水的，应该是满的瓶子，“full”表示满的。句意是不要扔掉里面还有水的满瓶子。故选B。 21.【答案】A 【解析】“if”引导条件状语从句，表示如果；“because”引导原因状语从句；“so”表示结果；“but”表示转折。这里表达如果现在不节约用水，未来就没有干净的水了，是条件关系。句意是记住，如果我们现在不节约用水，未来就不会有干净的水了。故选A。 22.【答案】C 【解析】“in the future”表明是将来的时间，要用一般将来时，“there be”句型的一般将来时结构是“there will be”。“is”是一般现在时；“are”是一般现在时复数形式；“was”是一般过去时。故选C。 23.【答案】A 【解析】“start with”是固定短语，表示“从……开始”。“at”通常用于表示时间点或小地点；“for”常表示目的、一段时间等；“from”表示“从……”，但“start from”更强调起点，“start with”更侧重于从某个具体事物开始。句意是让我们从小事做起。故选A。 24.【答案】C 【解析】根据前文强调要节约用水可知，这里是说永远不要浪费水。“Always”总是；“Usually”通常；“Sometimes”有时，都不符合语境。“Never”表示从不，永远不。故选C。 25.【答案】C 【解析】“tell sb. to do sth.”是固定用法，表示告诉某人做某事。“for”表示为了；“about”关于；“with”和……一起，均不符合此结构。句意是请告诉你的朋友们也节约用水。故选C。 四、阅读理解（共3篇，15小题，每小题2分，计30分） A On March 22nd, many schools celebrate World Water Day. Students learn why water is important. Only 1% of the Earth’s water is safe to drink. Teachers show videos about dry places where people walk far to get water. They teach easy ways to save water: ● Turn off taps when brushing teeth (this saves 8 liters a day!). ● Fix broken pipes quickly. Students make posters with words like “Save Water!” and draw pictures of reusing washing water for plants. They also play a game to guess how much water daily activities use.

A school water-saving activity B. How to drink water C. Fun games for children D. Life in dry places 26.【答案】A 【解析】文中提到“Only 1% of the Earth’s water is safe to drink.”，意思是地球上只有1%的水是可以安全饮用的。题干询问地球上我们能饮用的水的比例，A选项符合原文内容。故选A。 27.【答案】C 【解析】文中明确指出“Turn off taps when brushing teeth (this saves 8 liters a day!)”，即刷牙时关掉水龙头每天能节省8升水。A选项“Take short showers”文中未提及与节省8升水的关联；B选项“Fix pipes”是快速修理破裂的水管，并非节省8升水的方式；D选项“Reuse water”（再利用水）也不符合每天节省8升水的描述。故选C。 28.【答案】C 【解析】原文说“They also play a game to guess how much water daily activities use... The winner gets a special water bottle.”，意思是他们玩一个猜测日常活动用水多少的游戏，获胜者会得到一个特殊的水瓶。A选项“一本书”、B选项“一张海报”、D选项“一个玩具”均与原文不符。故选C。 29.【答案】B 【解析】文章最后提到“Now, students always check taps at home.”，即现在学生们总是在家检查水龙头。A选项“Take long baths”（长时间泡澡）与节约用水的活动目的相悖；C选项“Buy more bottles”（买更多的瓶子）在原文未提及；D选项“Dig wells”（挖井）也未在文中体现。故选B。 30.【答案】A 【解析】文章开篇指出在3月22日世界水日很多学校开展活动，接着介绍了活动中学生学习水的重要性、老师教的节水方法、学生制作海报、玩游戏等内容，最后提到活动后学生在家检查水龙头的行为，整体围绕学校的节水活动展开。B选项“How to drink water”（如何喝水）并非文章重点；C选项“Fun games for children”（孩子们的有趣游戏）只是活动中的一部分，不能概括全文；D选项“Life in dry places”（干旱地区的生活）只是老师展示视频中的内容，不是文章主要讲述的。故选A。 B The water cycle is very important for life on Earth. Let me tell you how it works. First, the sun shines on rivers, lakes and oceans. The heat makes water warm and go up into the air as very small drops. This is called evaporation. When these water drops go high into the sky, they get cold and come together to make clouds. This part is called condensation. Then, when the clouds become too heavy, the water falls back to the ground as rain or snow. We call this precipitation. The rainwater runs into rivers and lakes again, and some goes deep into the ground. Finally, the sun warms the water again, and the cycle starts over. This cycle gives us clean water to drink, so we must keep our rivers and oceans clean. 31.What makes water go up into the air? A. Wind B. Rain C. Sunlight D. Snow 32.What do we call the process of cloud formation? A. Evaporation B. Condensation C. Precipitation D. Collection 33.Why must we keep rivers clean? A. To make boats faster B. To have clean drinking water C. To help fish fly D. To stop the water cycle 34.What is the correct order of the water cycle? a. Rain falls b. Sun heats water c . Clouds form d. Water goes to rivers A. b→c→a→d B. c→b→a→d C. a→d→b→c D. d→a→b→c 35.What's the main idea of the text? A. How to make rain B. Why the sun is hot C. How nature reuses water D. Different kinds of clouds 31.【答案】C 【解析】文中提到“First, the sun shines on rivers, lakes and oceans. The heat makes water warm and go up into the air as very small drops.”，意思是太阳照耀在江河、湖泊和海洋上，热量使水变暖并以非常小的水滴形式升入空中。题干询问是什么使水升入空中，C选项“Sunlight（阳光）”符合原文描述。A选项“Wind（风）”、B选项“Rain（雨）”、D选项“Snow（雪）”均不符合使水升入空中的原因。故选C。 32.【答案】B 【解析】原文表述“When these water drops go high into the sky, they get cold and come together to make clouds. This part is called condensation.”，即当这些水滴升入高空时，它们变冷并聚集形成云，这一过程被称为凝结。A选项“Evaporation（蒸发）”是水变成水蒸气升入空中的过程；C选项“Precipitation（降水）”是云里的水以雨或雪的形式落到地面的过程；D选项“Collection（收集）”并非云形成过程的称呼。故选B。 33.【答案】B 【解析】文中提到“This cycle gives us clean water to drink, so we must keep our rivers and oceans clean.”，意思是水循环为我们提供了干净的饮用水，所以我们必须保持河流和海洋的清洁。A选项“To make boats faster（让船行驶得更快）”与保持河流清洁的原因无关；C选项“To help fish fly（帮助鱼飞行）”不符合常理；D选项“To stop the water cycle（阻止水循环）”与原文目的相悖。故选B。 34.【答案】A 【解析】根据文章内容，水循环的过程是：首先太阳加热水（b），接着水变成水蒸气升入高空后形成云（c），然后云太重时水以雨或雪的形式落下（a），最后雨水又流入河流（d）。所以正确顺序是b→c→a→d，A选项符合。故选A。 35.【答案】C 【解析】文章主要介绍了水循环的过程，包括蒸发、凝结、降水等环节，展示了大自然是如何循环利用水的。A选项“How to make rain（如何制造雨）”只是水循环过程中的一部分，不能概括全文；B选项“Why the sun is hot（为什么太阳是热的）”并非文章重点；D选项“Different kinds of clouds（不同种类的云）”也不是文章主要讲述的内容。故选C。 C Imagine this: Your alarm rings at 7 AM, but when you turn on the tap – no water! You can't brush your teeth or wash your face. Your hands stay sticky all day. At breakfast, there's no milk because cows need water too. You eat dry bread with jam. At school, the toilets smell bad because they can't flush. After running in P.E. class, your mouth feels like sand, but the water fountain is empty. At lunch, there's only cold sandwiches – no soup or juice. When you get home, the plants in the yard are dying. Mom says, "We can't wash vegetables or cook rice tonight." You use wet tissues to clean your hands. Before bed, you think: Water is more important than I ever knew! 36.Why can't you have milk for breakfast? A. No refrigerator B. Cows need water C. The shop is closed D. Mom forgets to buy 37.What problem happens in the school toilets? A. No paper B. They can't flush C. Doors are broken D. Lights don't work 38.How does your mouth feel after P.E. class? A. Sweet B. Like sand C. Cold D. Painful 39.What happens to the yard plants? A. Grow fast B. Turn colorful C. Start dying D. Produce fruit 40.What lesson does the story teach? A. Water is boring B. Water is everywhere C. Water is valuable D. Water tastes bad 36.【答案】B 【解析】文中提到“At breakfast, there's no milk because cows need water too”，意思是吃早饭的时候没有牛奶，因为奶牛也需要水。A选项“没有冰箱”、C选项“商店关门了”、D选项“妈妈忘记买了”在原文中均未提及，不是没有牛奶的原因。所以选B。 37.【答案】B 【解析】原文说“At school, the toilets smell bad because they can't flush”，即学校的厕所气味难闻，因为它们无法冲水。A选项“没有纸”、C选项“门坏了”、D选项“灯不亮了”在文中都没有相关描述，不符合学校厕所出现的问题。因此选B。 38.【答案】B 【解析】根据“After running in P.E. class, your mouth feels like sand”可知，体育课跑步后，你的嘴巴感觉像沙子一样干。A选项“甜甜的”、C选项“凉凉的”、D选项“疼痛的”均不符合原文描述。所以选B。 39.【答案】C 【解析】文中提到“When you get home, the plants in the yard are dying”，当你回到家，院子里的植物正在枯萎。A选项“长得快”、B选项“变得五颜六色”、D选项“结果实”与原文中植物的状态不符。故选C。 40.【答案】C 【解析】整个故事描述了没有水时生活中各个方面遇到的不便，最后提到“Water is more important than I ever knew”，说明水是很有价值的。A选项“水很无趣”与故事传达的意思相悖；B选项“水无处不在”并非故事重点强调的内容；D选项“水味道不好”在故事中未体现。所以选C。 五、补全对话（六选五）（共5小题，每小题2分，计10分） 根据对话内容，从方框中选择5个句子补全对话（其中两项多余）。 A: Hi, Li Ming!

We brush our teeth twice a day.（用she改写） She ______ ______ teeth twice a day. 45. There is little water in the desert.（改为同义句） There ______ ______ water in the desert. 41.【答案】Don't turn 【解析】原句“Turn off the tap.”是祈使句，祈使句的否定形式通常是在动词原形前加“Don't”。句意是“关掉水龙头”，否定后为“不要关掉水龙头”。故填Don't turn。 42.【答案】How wide 【解析】原句中划线部分“20 meters wide”表示湖泊的宽度，对其提问要用“How wide”，意思是“多宽”。句意是“这个湖20米宽”，提问后为“这个湖多宽？” 故填How wide。 43.【答案】Save water 【解析】将陈述句改为祈使句，通常省略主语，直接用动词原形开头。原句“We must save water.”（我们必须节约用水）改为祈使句就是“Save water”（节约用水）。故填Save water。 44.【答案】brushes her 【解析】原句“We brush our teeth twice a day.”是一般现在时，用“she”改写时，主语变为第三人称单数，动词“brush”要变为第三人称单数形式“brushes”，形容词性物主代词“our”要根据“she”变为“her”。句意是“我们每天刷两次牙”，改写后为“她每天刷两次牙”。故填brushes her。 45.【答案】isn't much 【解析】“little”表示“几乎没有”，修饰不可数名词，其同义表达可以用“not much”。原句“There is little water in the desert.”（沙漠里几乎没有水），同义句为“There isn't much water in the desert.”。故填isn't much。 VII. 完成句子（共5小题，每小题2分，计10分） 46. 请每天关掉水龙头。 Please __________ __________ the tap every day. 47. 地球上97%的水是海水。 97% of the water on the earth __________ __________ water. 48. 我们可以用雨水浇花。 We can __________ rainwater __________ water plants. 49. 不要往河里扔垃圾！ __________ __________ rubbish into the river! 50. 每一滴水都很重要。 __________ __________ __________. 46.【答案】turn off 【解析】“关掉”的英文表达是“turn off”，“Please”后面接动词原形。故填turn off。 47.【答案】is sea 【解析】“97% of the water”作主语，谓语动词的单复数取决于“water”，“water”是不可数名词，所以谓语动词用“is”；“海水”是“sea water”。故填is sea。 48.【答案】use; to 【解析】“用……来做某事”可以用“use... to do sth.”表达，“can”是情态动词，后面接动词原形。故填use; to。 49.【答案】Don't throw 【解析】这是一个祈使句的否定形式，在动词原形“throw”前加“Don't”。故填Don't throw。 50.【答案】Every drop counts 【解析】“每一滴水”是“Every drop”，“重要，有价值”用“count”表示，这里用一般现在时，“drop”是单数，动词用第三人称单数形式“counts”。故填Every drop counts。 原创精品资源学科网独家享有版权，侵权必究！ 第 1 页 共 7 页 学科网（北京）股份有限公司 $$
