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. 1．What makes water go up into the air? A．Wind. B．Rain. C．Sunlight.

It is rightly called the “elixir (灵丹妙药) of life”, as no life can live without it. Although nearly 70% of the Earth’s surface is covered with water, only a small part is fresh and fit for drinking. This makes it essential to save water and use it wisely. Water is needed for many activities in our daily life, such as drinking, cooking, cleaning and farming. Plants, animals and humans all depend on water to live. Farmers need water for growing crops, and industries need water for producing goods. Moreover, water is necessary for keeping us clean and staying healthy. Without water, it is impossible to maintain hygiene (卫生) or prevent diseases. Sadly, water scarcity (短缺) is a growing problem in many parts of the world. Overuse, pollution, and climate change have made clean water harder to find. Many people still lack access to safe drinking water, which affects their health and quality of life. To protect this precious resource, we must avoid wasting water and keep our rivers and lakes clean. Water is life. We must save it for ourselves and for future generations. 1．Why is water called the “elixir of life”? A．It supports all life. B．It creates all wealth. C．It provides all energy. D．It cures many diseases. 2．Which of the following is NOT mentioned as a use of water in daily life? A．Drinking. B．Cleaning. C．Farming. D．Transportation. 3．What are the main causes of water scarcity mentioned in the passage? A．Natural disasters and droughts. B．Poor water management systems. C．Overuse, pollution, and climate change. D．Population growth and industrialization. 4．What can we infer about the future of water resources? A．Water will become enough to use. B．Technology will solve all problems. C．More protective measures are needed. D．The situation will improve naturally. 5．Which sentence best expresses the main idea of the passage? A．Many people still lack access to safe drinking water. B．Water is needed for many activities in our daily life. C．Plants, animals and humans all depend on water to live. D．We should save water for ourselves and future generations. 【答案】1．A 2．D 3．C 4．C 5．D 【导语】本文主要介绍了水资源的相关情况，并呼吁人们保护水资源。 1．细节理解题。根据第一段中“It is rightly called the ‘elixir of life’, as no life can live without it.”可知，水被称为“长生不老药”，是因为它维持所有的生命。故选A。 2．细节理解题。根据第二段中“Water is needed for many activities in our daily life, such as drinking, cooking, cleaning and farming.”可知，我们日常生活中的许多活动都需要水，如饮用、烹饪、清洁和耕种，未提到运输。故选D。 3．细节理解题。根据第三段中“Overuse, pollution, and climate change have made clean water harder to find.”可知，文章中提到的水资源短缺的主要原因是过度使用、污染和气候变化。故选C。 4．推理判断题。根据最后一段中“We must save it for ourselves and for future generations.”可推知，未来需要更多保护水资源的措施。故选C。 5．主旨大意题。通读全文可知，本文主要介绍了水资源的相关情况，并呼吁人们保护水资源。故选D。 重难语篇拔高练 The Seine (塞纳河) is a beautiful river which goes through France. However, the Seine has been seriously polluted. There are even laws that do not let people swim in the water. 11-year-old Raphael wants to clean the river. He wants people to swim in the Seine by 2024. Cleaning the river is a big job. Raphael fishes rubbish out of the river. He has done it nearly every weekend for the past two years. He fishes with his dad. They can catch a ton of rubbish in a single day. They have caught anything from phones to scooters (滑板车). The biggest thing Raphael found was a motorcycle. It was so heavy that it took a team of people to pull it out. Raphael learned about cleaning rivers from YouTube. In 2019, he found a video. People were fishing metal objects out of rivers. They used ropes tied to magnets (磁铁). That Christmas, Raphael asked his parents for supplies (供给). He wanted some ropes, a hook, and a powerful magnet. The magnet was very strong. It could attract metal objects weighing more than a ton. When he began, fishing for metal was just a lazy weekend activity. But Raphael soon saw just how much rubbish there was at the bottom of the river. He wanted to do more. It became like a full-time job, he said. Last October, Raphael won an award for his efforts. He received the Medal of Paris. Raphael feels happy about his progress in the last two years. A part of the Seine is clearer than the rest of the river. That is where he first started fishing for metal. Raphael cannot clean the river alone by 2024, but he won’t give up. He hopes he is one of the first to swim in the water once it is safe. 1．Raphael cleans the river in order to ______. A．swim in the Seine B．win the Medal of Paris C．become famous in France D．learn from You Tube 2．Which paragraph shows how hard the job of cleaning the river is? A．Paragraph 1. B．Paragraph2.

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. 1．How much water can we drink on Earth? A．1%. B．10%. C．25%.

Scientists study them to know about the history of the earth and the change of weather. They’re both super cold, but what else do you know about them? First, the Arctic is in the north, while the Antarctica sits in the south. Imagine a big ball with snow and ice at both ends—that’s what our earth looks like! There isn’t just snow or ice. They have beautiful views (风景) and some special animals, too. You might think polar bears and penguins (企鹅) live together. No! Polar bears live in the Arctic, while penguins live in the Antarctica. But you can see seals and fish around both places. Are there people around these places? About 4,000,000 people live near the Arctic, but no one lives in the Antarctica all year round! Now here comes a surprise. A few parts of the Arctic and most of the Antarctica get almost no rain, so they are among the driest (最干燥的) places on the earth. The Antarctica is the world’s largest desert (沙漠)! Yes, a desert with snow and ice! However, the ice is melting (融化) these years. How can we take care of these amazing places? Get more information on the Internet. Maybe you’ll find your ways to help. 1．In the following pictures, what animals only live in the Arctic?

Although nearly 70% of the Earth’s surface is covered with water, only a small part is fresh and fit for drinking. This makes it essential to save water and use it wisely. Water is needed for many activities in our daily life, such as drinking, cooking, cleaning and farming. Plants, animals and humans all depend on water to live. Farmers need water for growing crops, and industries need water for producing goods. Moreover, water is necessary for keeping us clean and staying healthy. Without water, it is impossible to maintain hygiene (卫生) or prevent diseases. Sadly, water scarcity (短缺) is a growing problem in many parts of the world. Overuse, pollution, and climate change have made clean water harder to find. Many people still lack access to safe drinking water, which affects their health and quality of life. To protect this precious resource, we must avoid wasting water and keep our rivers and lakes clean. Water is life. We must save it for ourselves and for future generations. 1．Why is water called the “elixir of life”? A．It supports all life. B．It creates all wealth. C．It provides all energy. D．It cures many diseases. 2．Which of the following is NOT mentioned as a use of water in daily life? A．Drinking. B．Cleaning. C．Farming. D．Transportation. 3．What are the main causes of water scarcity mentioned in the passage? A．Natural disasters and droughts. B．Poor water management systems. C．Overuse, pollution, and climate change. D．Population growth and industrialization. 4．What can we infer about the future of water resources? A．Water will become enough to use. B．Technology will solve all problems. C．More protective measures are needed. D．The situation will improve naturally. 5．Which sentence best expresses the main idea of the passage? A．Many people still lack access to safe drinking water. B．Water is needed for many activities in our daily life. C．Plants, animals and humans all depend on water to live. D．We should save water for ourselves and future generations. 重难语篇拔高练 The Seine (塞纳河) is a beautiful river which goes through France. However, the Seine has been seriously polluted. There are even laws that do not let people swim in the water. 11-year-old Raphael wants to clean the river. He wants people to swim in the Seine by 2024. Cleaning the river is a big job. Raphael fishes rubbish out of the river. He has done it nearly every weekend for the past two years. He fishes with his dad. They can catch a ton of rubbish in a single day. They have caught anything from phones to scooters (滑板车). The biggest thing Raphael found was a motorcycle. It was so heavy that it took a team of people to pull it out. Raphael learned about cleaning rivers from YouTube. In 2019, he found a video. People were fishing metal objects out of rivers. They used ropes tied to magnets (磁铁). That Christmas, Raphael asked his parents for supplies (供给). He wanted some ropes, a hook, and a powerful magnet. The magnet was very strong. It could attract metal objects weighing more than a ton. When he began, fishing for metal was just a lazy weekend activity. But Raphael soon saw just how much rubbish there was at the bottom of the river. He wanted to do more. It became like a full-time job, he said. Last October, Raphael won an award for his efforts. He received the Medal of Paris. Raphael feels happy about his progress in the last two years. A part of the Seine is clearer than the rest of the river. That is where he first started fishing for metal. Raphael cannot clean the river alone by 2024, but he won’t give up. He hopes he is one of the first to swim in the water once it is safe. 1．Raphael cleans the river in order to ______.
