It makes up about sixty percent of your body weight. Most of us get our water at a low price from the taps. But some people prefer bottled water, even though it costs more. Bottled water first appeared in the United States in the 1760s. A company called Jackson’s Spa sold bottled water. It said that the water could be good for people’s health. Since then, bottled water has become more and more popular worldwide. In 2019, for the first time, Americans drank more bottled water than soda. Why has bottled water become so popular? Well, this may have something to do with people’s worries about the purity (纯净) of tap water. According to one survey, 63 percent of Americans worried a lot about the safety of their drinking water. However, research suggests such worries are unnecessary. For most families, bottled water isn’t better than tap water. In fact, almost half of all bottled water comes from the tap. When it comes to taste, most of us can’t tell the difference. Once a blind taste test was done and only a third of the taste-testers were able to correctly pick out which one was from tap water. Making bottled water, however, requires lots of things. Plastic bottles are usually used only once before being thrown away. Besides, more water goes into the making of a bottle of water. One study found that companies usually use 1.39 litres (升) of water to make one litre of bottled water. Do you prefer bottled water to tap water? It’s time to change your mind! Bottled water is more expensive. However, it isn’t much better than the water you get from your kitchen tap. Task 1: Answer the questions: 1．Bottled water is cheaper than tap water, isn’t it? 2．When did bottled water first appear in America? 3．Why is bottled water popular with Americans? 4．Why was a blind taste test done? 5．How does the writer show the fact that more water goes into the making of a bottle of water? 6．What is the writer’s attitude towards tap water? Task 2: 7．Write more about the advantages of tap water or the disadvantages of bottled water in about 30 words. 【答案】1．No, it isn’t. 2．In the 1760s. 3．Because people worried about the purity of tap water. 4．To see if most of us can tell the difference between bottled water and tap water in taste. 5．By citing a study. 6．Positive. 7．Tap water is much cheaper, tastes almost the same and causes no plastic pollution, while bottled water wastes resources, creates plastic rubbish and needs extra fuel in transportation. 【导语】本文主要讨论了瓶装水在美国的起源、流行原因、与自来水的比较，以及瓶装水生产对环境的影响。文章旨在提醒读者瓶装水并非比自来水更优越，且生产过程中存在资源浪费问题。 1．根据文章中的“But some people prefer bottled water, even though it costs more.”可知，瓶装水比自来水贵，而不是便宜。故填No, it isn’t. 2．根据文章中的“Bottled water first appeared in the United States in the 1760s”可知，瓶装水首次出现在美国是在18世纪60年代。故填In the 1760s. 3．根据文章中的“this may have something to do with people’s worries about the purity (纯净) of tap water”可知，瓶装水在美国受欢迎的原因可能与人们对自来水纯净度的担忧有关。故填Because people worried about the purity of tap water. 4．根据文章中的“Once a blind taste test was done and only a third of the taste-testers were able to correctly pick out which one was from tap water.”可知，进行盲品测试是为了看我们大多数人是否能品尝出瓶装水和自来水在味道上的差异。故填To see if most of us can tell the difference between bottled water and tap water in taste. 5．根据文章中的“One study found that companies usually use 1.39 litres (升) of water to make one litre of bottled water.”可知作者通过引用一项研究来说明生产一瓶瓶装水需要消耗更多的水。故填By citing a study. 6．根据文章中的“However, it isn’t much better than the water you get from your kitchen tap.”可知，作者认为自来水并不比瓶装水差很多，因此作者对自来水的态度是积极的。故填Positive. 7．这是一个开放性问题，答案因人而异。但可以根据文章内容和常识来回答。故填Tap water is much cheaper, tastes almost the same and causes no plastic pollution, while bottled water wastes resources, creates plastic rubbish and needs extra fuel in transportation. Read the passage and complete the tasks. (根据短文内容完成任务。) A new fleet of ocean-cleaning drones is being tested to remove plastic waste from the sea. These autonomous (自动的) devices use AI to detect and collect floating debris (碎片), helping to reduce the millions of tons of plastic polluting the oceans. The drones operate day and night, covering large areas more efficiently than human-led clean-up efforts. Traditional clean-up methods involve ships and nets, which are slow, expensive, and often harm marine life. The drones, however, are designed to avoid wildlife while targeting only plastic waste. Early trials show they can collect up to 100 kilograms of debris per day, making them a promising solution for large-scale ocean clean-up. One challenge is that strong ocean currents can push debris out of reach, making it harder for the drones to operate effectively. Dr. Hannah Lee, the project coordinator, says her team is improving the drones’ navigation systems to handle rough sea conditions. They are also developing ways to recycle the collected plastic into usable materials. If successful, these drones could play a key role in restoring marine ecosystems and protecting sea life. This technology offers hope for a cleaner, healthier ocean in the future. Task 1 Answer the questions 1．How do the drones identify plastic waste in the ocean? 2．Why are drones better than traditional clean-up methods? 3．How much debris can each drone collect daily? 4．What problem do strong ocean currents cause for the drones? 5．What aspect of the drones is Dr. Lee’s team improving?        Task 2 6．Explain how ocean-cleaning drones help marine life. (不超过30个词) 【答案】1．They use AI to detect and collect floating debris. 2．Because they are faster, cheaper, and do not harm marine life. 3．Up to 100 kilograms. 4．They push debris out of reach, making it harder for the drones to operate effectively. 5．The drones’ navigation systems. 6．They can help to clean up the ocean and protect marine life. 【导语】本文是一篇说明文。主要介绍了一款正在测试的海洋清洁无人机，包括其工作原理、相比传统清洁方式的优势、面临的挑战及未来意义。该无人机借助人工智能检测和收集海洋塑料垃圾，虽受洋流影响，但经改进后有望助力海洋生态恢复。 1．根据“These autonomous (自动的) devices use AI to detect and collect floating debris (碎片), helping to reduce the millions of tons of plastic polluting the oceans.”可知，它们利用人工智能来检测和收集流动塑料垃圾。故填They use AI to detect and collect floating debris. 2．根据“Traditional clean-up methods involve ships and nets, which are slow, expensive, and often harm marine life. The drones, however, are designed to avoid wildlife while targeting only plastic waste.”可知，因为它们更快，更便宜，不伤害海洋生物。故填Because they are faster, cheaper, and do not harm marine life. 3．根据“Early trials show they can collect up to 100 kilograms of debris per day, making them a promising solution for large-scale ocean clean-up.”可知，每架无人机每天可收集多达100公斤碎片。故填Up to 100 kilograms. 4．根据“One challenge is that strong ocean currents can push debris out of reach, making it harder for the drones to operate effectively.”可知，它们把碎片推到无法到达的地方，使无人机更难有效运行。故填They push debris out of reach, making it harder for the drones to operate effectively. 5．根据“Dr. Hannah Lee, the project coordinator, says her team is improving the drones’ navigation systems to handle rough sea conditions.”可知，正在改进无人机导航系统。故填The drones’ navigation systems. 6．根据最后一段“If successful, these drones could play a key role in restoring marine ecosystems and protecting sea life. This technology offers hope for a cleaner, healthier ocean in the future.”可知，它们可以帮助清理海洋，保护海洋生物。故填They can help to clean up the ocean and protect marine life. Answer the questions（根据短文内容回答下列问题） Different from Earth Day which falls on April 22 every year, Earth Hour has been known for its “lights off” moment. On March 22, 2025, from 8:30 PM to 9:30 PM, millions turned off their lights to show they cared about the Earth. This year’s Earth Hour, with the theme (主题) “Create the Biggest Hour for Earth”, was even more important because it shared the same day as World Water Day. However, it’s not enough to have such an hour every year. What matters is how we can be kinder to the earth every day. Planet-friendly food You might not realize it, but the meat industry has a huge influence on forests around the world. Large numbers of trees are cut down to make space for soy (大豆) and other plants that are used to feed animals. Have a chat with your parents about going meat-free, even for a few days every week. Also, foods like vegetables, fruit and nuts are helping the planet. Go green and save money, too Electricity (电) produced by burning fuels like oil, coal and gas causes global warming and pollution. Ask your parents how they heat your home and suggest using green energy like wind or solar power (太阳能). Another tip is to remember to turn off the electricity whenever you leave a room. Cutting down on screen time is actually good for both your health and the earth. Waste Less, Help more Waste is a big problem! We’ve talked about saving electricity. What about food waste? Every year, 1.3 billion tonnes of food is wasted around the world. That’s one-third of the total amount, which can feed up to 1.26 billion people. Try to talk to your parents about buying a proper amount of food. More importantly, find some ways online for leftover food at home. 1．When did Earth Hour take place in 2025? 2．Why was Earth Hour 2025 especially important? 3．How does the meat industry negatively affect forests? 4．Why is electricity produced by burning fuels harmful to the environment? 5．One-third of the world’s food is wasted, isn’t it? 6．As teenagers, what can we do to contribute to Earth Hour and environmental protection beyond just turning off lights for one hour? 【答案】1．Earth Hour took place in 2025 on March 22, from 8:30 PM to 9:30 PM. 2．Because it shared the same day as World Water Day. 3．Large numbers of trees are cut down to make space for soy and other plants used to feed animals. 4．Because it causes global warming and pollution. 5．Yes, it is. 6．As teenagers, we can contribute by choosing plant-based foods like vegetables, fruit and nuts, turning off electricity when not in use and reducing screen time. (Any reasonable answer is accepted.) 【导语】本文以2025年地球一小时活动为契机，指出环保不应仅限于年度象征性行动，而应转化为日常实践，并通过三大维度提出了三条具体建议。 1．根据“On March 22, 2025, from 8:30 PM to 9:30 PM, millions turned off their lights to show they cared about the Earth.”可知，“地球一小时”活动于2025年3月22日晚上8:30至9:30举行。故填Earth Hour took place in 2025 on March 22, from 8:30 PM to 9:30 PM. 2．根据“This year’s Earth Hour, with the theme (主题) ‘Create the Biggest Hour for Earth’, was even more important because it shared the same day as World Water Day.”可知，2025年的“地球一小时”特别重要是因为它与世界水日是同一天。故填Because it shared the same day as World Water Day. 3．根据“You might not realize it, but the meat industry has a huge influence on forests around the world. Large numbers of trees are cut down to make space for soy (大豆) and other plants that are used to feed animals.”可知，肉类产业大量树木被砍伐，为大豆和其他用于饲养动物的植物腾出空间，从而对森林产生负面影响。故填Large numbers of trees are cut down to make space for soy and other plants used to feed animals. 4．根据“Electricity (电) produced by burning fuels like oil, coal and gas causes global warming and pollution.”可知，燃烧燃料产生的电力对环境有害是因为它会导致全球变暖和污染。故填Because it causes global warming and pollution. 5．根据“Every year, 1.3 billion tonnes of food is wasted around the world. That’s one-third of the total amount”可知，世界上三分之一的食物被浪费了。故填Yes, it is. 6．开放性试题，言之有理即可。参考答案为As teenagers, we can contribute by choosing plant-based foods like vegetables, fruit and nuts, turning off electricity when not in use and reducing screen time.      Nowadays water pollution is becoming an important problem. We can hear about water pollution from TV sometimes. A report shows that more than one third of the country’s industrial waste water flows directly into rivers and lakes. The water environment in most cities around the country is declining(下降). An official report from the Ministry of Environment Protection(环保总局 ) shows that among the investigated 131 rivers that flow through cities, 36 are severely(严重) polluted, and nearly 60 others polluted. Since the Songhua River benzene(苯) pollution incident in 2005, over 140 pollution cases have been reported. The Yellow River, an important water resource for North China, is suffering from serious pollution. Nearly 40 percent of its mainstream has been severely polluted. And situation is no better for the Huai River, in which the country has invested(投入) most. It is also a severely polluted river.    Water, like the air, is another basic substance(物质) of human life. But the fact is that more and more water is being polluted. The available drinking water is declining. Some factories are only busy developing their factories, without any thought of protecting the environment. They pour the waste water into rivers and oceans as they like. Although sometimes they are forbidden and punished, after that they will continue to do as usual because of money. In brief, it’s time for us to take steps to improve our living environment before it is too late. 1．What flows directly into rivers and lakes according to the first paragraph? 2．How many of the investigated 131 rivers are severely polluted? 3．When did the Songhua River benzene pollution incident take place? 4．Four rivers are mentioned in the passage, aren’t they? 5．Why will the factories continue to pour waste water into rivers? 【答案】1．Industrial waste water. 2．36. 3．In 2005. 4．No, they aren’t. 5．Because of money. 【导语】本文主要讲述的是在我国一些工厂为了经济利益，排放污水导致我国的河流和湖泊受污染。 1．根据文中第一段“A report shows that more than one third of the country’s industrial waste water flows directly into rivers and lakes.”可知超过三分之一的废水直接流入河流和湖泊，所以是工业废水直接流入河流和湖泊。故填Industrial waste water. 2．根据文中第二段“36 are severely(严重) polluted”可知，在调查的131条河流中有36条河流被严重污染。故填36。 3．根据文中第三段“Since the Songhua River benzene(苯) pollution incident in 2005”可知，松花江苯污染事件发生在2005年。故填In 2005. 4．根据文中第三段“the Songhua River”，第四段“The Yellow River”，第五段“the Huai River”可知，本文共谈到了三条河流，分别是松花江、黄河、淮河，所以题干中说本文提到四条河流是不正确的。故填No, they aren’t. 5．根据文中第六段“after that they will continue to do as usual because of money”可知，这些工厂为了钱，即使被禁止、被惩罚，之后他们仍继续向河里排放污水。故填Because of money. Answer the questions (根据短文内容回答下列问题)     It was 10 p.m. on a Wednesday night. Fourteen-year-old Li Gong sat at his desk and stared at a blank sheet of paper. Li had to write a 600-word book report and it was due the next day. The problem? He hadn’t read the book. Li opened an AI app on his computer and typed in “Book report, 600 words, The Old Man and the Sea.” In less than a minute, the boy had his book report. Several days later, Li was called into his teacher’s office. Unfortunately, his teacher was very familiar with computers and AI apps. One of the apps scanned (扫描) his students’ writing to detect cheating. Li had been caught! But his teacher was kind. Instead of punishing the boy, he explained that although AI apps were a helpful shortcut for some things, there was no shortcut to learning. Learning how to write well is valuable to understanding a subject and expressing your own ideas about it. An AI app depends on a collection of information that someone has uploaded onto a computer system. A specially trained algorithm (算法) processes the information to produce the type of writing someone might need. It’s useful for writing business emails, legal documents (法律文件) and even news reports, but it’s not useful for expressing your personal ideas and thoughts. Writing is the most difficult of all the language skills. You need to be good at grammar and have a good vocabulary. Writing also requires you to think clearly. For example, Li Gong was supposed to read Ernest Hemingway’s The Old Man and the Sea and find out what it was about. It’s the story of a poor fisherman who catches a big fish one day. It’s too big to put in his boat, so he drags it behind him in the water. When he reaches the shore, all that is left is the fish’s skeleton. It’s a sad story, but what does it all mean? If Li had read the book and written the book report, he would have learned a lot and had the satisfaction of expressing his own ideas about the story. That’s something AI cannot do. 1．Li Gong finished his book report on The Old Man and the Sea on his own, didn’t he? 2．How does an AI app produce a piece of writing? 3．What do you need to do in order to be able to write well? 4．Who wrote the book The Old Man and the Sea? 5．According to the author, what is AI unable to do? 6．Now that AI can “write”, do you think it is still necessary for students to learn how to write well? Give your reason(s). 【答案】1．No, he didn’t. 2．By using a specially trained algorithm to process the information. 3．I need to be good at grammar, have a good vocabulary and think clearly. 4．Ernest Hemingway. 5．Express personal ideas and thoughts. 6．Yes. Because learning how to write requires me to think deeply, organize my thoughts and try to communicate those thoughts clearly and effectively. Learning how to write well is valuable to understanding a subject and expressing my own ideas about it. Writing can help me to become a better thinker and communicator. 【导语】本文通过讲述李工的故事告诉我们人工智能并不能代替人类表达个人想法和观点。 1．根据“Li opened an AI app on his computer and typed in ‘Book report, 600 words, The Old Man and the Sea.’ In less than a minute, the boy had his book report.”可知李工是用AI写的《老人与海》读书报告，并不是他独立完成的。故填No, he didn’t. 2．根据“A specially trained algorithm (算法) processes the information to produce the type of writing someone might need.”可知一种经过专门训练的算法会处理这些信息，生成某人可能需要的写作内容。故填By using a specially trained algorithm to process the information. 3．根据“Writing is the most difficult of all the language skills. You need to be good at grammar and have a good vocabulary. Writing also requires you to think clearly.”可知写作需要掌握扎实的语法知识，并拥有丰富的词汇量，此外还需要具备清晰的思维能力。故填I need to be good at grammar, have a good vocabulary and think clearly. 4．根据“For example, Li Gong was supposed to read Ernest Hemingway’s The Old Man and the Sea and find out what it was about.”可知《老人与海》是海明威写的。故填Ernest Hemingway. 5．根据“It’s useful for writing business emails, legal documents (法律文件) and even news reports, but it’s not useful for expressing your personal ideas and thoughts.”可知人工智能不能表达个人想法和观点。故填Express personal ideas and thoughts. 6．开放性试题，言之有理即可。参考答案为Yes. Because learning how to write requires me to think deeply, organize my thoughts and try to communicate those thoughts clearly and effectively. Learning how to write well is valuable to understanding a subject and expressing my own ideas about it. Writing can help me to become a better thinker and communicator. Kuakuaqun is social media chat groups that people pay a little money to join and are paid to show kindness, support and comfort to others in the group. The new chat groups have become popular with young people. According to media reports, the first such online praise group was formed by a few users of Douban, one of the major online social networks, for fun. However, the idea has caught on and praise-seeking chat groups have become popular among college students across the country. It was hard to understand Kuakuaqun at first. What kind of value do kind words have if I am paying someone to say them? Lin Yingying from Quanzhou described the groups as “a joke”, but also offered some insight (见解). “We rarely hear nice things in real life,” Lin said, “maybe we are not good at telling people...that we are not feeling well...” She thinks it is easier for people to share their problems online. Kuakuaqun doesn’t only exist in China. No matter where you come from, it is common to hear someone say, “You are not good enough.” There is a certain beauty in giving encouragement to others. Perhaps that is why so many young people have joined the groups. A reporter from Russia Today wrote about a post in which someone admitted that they woke up at 2 pm one day. One user replied, “You must care about your health very much as you sleep for so long, praise you.” That praise sounds hollow, but the humor doesn’t. Maybe that is the real value. A good joke can brighten anybody’s day. Experts have said that the popularity of Kuakuaqun reflects the users’ stressful, anxious and lonely mentalities (心态). It creates a positive and friendly environment for people that may help them get confidence again. 1．What is Kuakuaqun? 2．Where have praise-seeking chat groups become popular? 3．It was easy to understand Kuakuaqun at first, wasn’t it? 4．Why does Lin Yingying from Quanzhou think people share problems more easily online? 5．What does the popularity of kuakuaqun reflect according to experts? 6．Do you want to join Kuakuaqun? Why or why not? 【答案】1．Kuakuaqun is social media chat groups that people pay a little money to join and are paid to show kindness, support and comfort to others in the group. 2．Among college students across the country. 3．No, it wasn’t. 4．Because people rarely hear nice things in real life and are not good at telling others that they are not feeling well. 5．It reflects the users’ stressful, anxious and lonely mentalities. 6．Yes. Because it creates a positive environment and helps people regain confidence. 【导语】本文是一篇说明文。主要介绍了“夸夸群”这一新兴社交媒体聊天群的起源、功能、流行原因及其反映的社会心态。 1．根据“Kuakuaqun is social media chat groups that people pay a little money to join and are paid to show kindness, support and comfort to others in the group.”可知，夸夸群是一种社交媒体聊天群，人们付费加入并通过表达善意、支持和安慰他人获得报酬。故填Kuakuaqun is social media chat groups that people pay a little money to join and are paid to show kindness, support and comfort to others in the group. 2．根据“praise-seeking chat groups have become popular among college students across the country.”可知，夸夸群在全国大学生中流行。故填Among college students across the country. 3．根据“It was hard to understand Kuakuaqun at first.”可知，最初理解夸夸群并不容易。故填No, it wasn’t. 4．根据“‘We rarely hear nice things in real life,’ Lin said, ‘maybe we are not good at telling people...that we are not feeling well...’”可知，她认为人们在现实生活中很少听到赞美，也不擅长表达自己的负面情绪，所以人们更容易在网上分享他们的问题。故填Because people rarely hear nice things in real life and are not good at telling others that they are not feeling well. 5．根据“Experts have said that the popularity of Kuakuaqun reflects the users’ stressful, anxious and lonely mentalities (心态).”可知，专家认为夸夸群的流行反映了用户压力大、焦虑和孤独的心态。故填It reflects the users’ stressful, anxious and lonely mentalities. 6．开放性试题，答案不唯一，言之有理即可。参考答案为Yes. Because it creates a positive environment and helps people regain confidence. What did people from the New Stone Age look like? For a long time, nobody knew. But modern technologies have now showed us the faces of two men from that time. Last month, a group of Chinese researchers released the portraits (肖像) of these two men. They were based on their skulls. These head bones were discovered at the Yangshao Village site in Henan Province. The researchers believe the two men both lived near the Yellow River. One man likely lived around 5, 600 years ago, during the Yangshao culture. He was about 40 years old when he died. The other was around 50. He might have lived about 4, 000 years ago. This was the Longshan culture period. At present, there are no written records of these ancient people. The researchers collected lots of data from the skulls. They used the data to create 3D models of the men’s faces. Then, they studied populations with the closest genetic (基因的) background. This helped them to rebuild the muscles. Genetic studies also showed other features of the two men. These include their skin color and what their hair was like. “The project lets us know the faces of our ancestors,” said one of the researchers. “It also helps us learn something about the rich cultures of ancient society. ” 1．What did the researchers base the portraits of the two men on? 2．Where were the head bones of the two men discovered? 3．When did the man from the Yangshao culture likely live? 4．At present, there are no written records of these ancient people, are there? 5．How did the researchers rebuild the muscles of the two men’s faces? 6．What can we learn from this project according to the passage? 【答案】1．Their skulls. 2．At the Yangshao Village site in Henan Province. 3．Around 5,600 years ago. 4．No, there aren’t. 5．By collecting lots of data from the skulls to create 3D models of the men’s faces and studying populations with the closest genetic background. 6．We can learn the faces of our ancestors and something about the rich cultures of ancient society. 【导语】本文是一篇说明文，介绍了中国研究人员通过现代技术，基于在河南仰韶村遗址发现的头骨，还原了新石器时代两名男性的肖像，以及相关研究过程和意义。 1．根据“Last month, a group of Chinese researchers released the portraits of these two men. They were based on their skulls.”可知，研究人员绘制这两名男性的肖像依据的是他们的头骨。故填Their skulls. 2．根据“These head bones were discovered at the Yangshao Village site in Henan Province.”可知，这两名男性的头骨是在河南省仰韶村遗址被发现的。故填At the Yangshao Village site in Henan Province. 3．根据“One man likely lived around 5,600 years ago, during the Yangshao culture.”可知，仰韶文化时期的那名男性可能生活在大约5600年前。故填Around 5,600 years ago. 4．根据“At present, there are no written records of these ancient people.”可知，目前没有关于这些古代人的书面记录，反意疑问句的回答要根据实际情况，事实是没有，所以回答是No, there aren’t. 故填No, there aren’t. 5．根据“The researchers collected lots of data from the skulls. They used the data to create 3D models of the men’s faces. Then, they studied populations with the closest genetic background. This helped them to rebuild the muscles.”可知，研究人员通过收集头骨数据创建面部3D模型，研究基因背景最接近的人群来重建面部肌肉。故填By collecting lots of data from the skulls to create 3D models of the men’s faces and studying populations with the closest genetic background. 6．根据文章最后一段“‘The project lets us know the faces of our ancestors,’ said one of the researchers. ‘It also helps us learn something about the rich cultures of ancient society.’”可知，这个项目让我们了解到了祖先的面容，还帮助我们了解古代社会丰富的文化。故填We can learn the faces of our ancestors and something about the rich cultures of ancient society. 阅读文章回答问题 Curiosity: The Key to Great Discoveries Throughout history, curiosity has been the driving force behind some of the most important discoveries. Take Galileo Galilei, for example. As a young man, he was curious about the stars and planets. While others believed the Earth was the center of the universe, Galileo wondered if that was true. He built a telescope to observe the sky and found that the Earth orbits the sun—a discovery that changed science forever.   Another example is Marie Curie, who was curious about unknown elements. She spent years studying radioactive materials, even when many people thought it was a waste of time. Her curiosity led to the discovery of radium, which has helped save millions of lives through cancer treatment.   Curiosity isn’t just for famous scientists. It’s part of everyday life. A teacher in a small village noticed that her students were curious about plants. Instead of just telling them facts, she encouraged them to grow their own. The students began asking questions: Why do some plants need more water? How do they make food? Through exploring, they learned more than any textbook could teach.   In fact, research shows that curious people are more successful in life. They are better at solving problems and adapting to new situations. This is because curiosity makes the brain more active and ready to learn. When we’re curious, we pay more attention and remember information better.   So, the next time you wonder “why” or “how”, don’t ignore it. Follow your curiosity—it might just lead you to something amazing. 1．What did Galileo discover by observing the sky with a telescope?   2．How did Marie Curie’s curiosity help save lives?   3．What did the village teacher do to encourage her students’ curiosity?   4．Why are curious people more successful in life according to research?   5．What does the author advise us to do when we feel curious?   【答案】1．He found that the Earth orbits the sun. 2．Her discovery of radium has helped save millions of lives through cancer treatment. 3．She encouraged them to grow their own plants and explore. 4．Because curiosity makes the brain more active and ready to learn, helping them solve problems and adapt to new situations. 5．The author advises us to follow our curiosity instead of ignoring it. 【导语】本文主要讲述了好奇心在重大发现和日常生活中的重要性，并通过伽利略、居里夫人和一位乡村教师的例子加以说明。 1．根据文章第1段“He built a telescope to observe the sky and found that the Earth orbits the sun—a discovery that changed science forever.”可推知，伽利略通过望远镜发现地球绕太阳运行。故填He found that the Earth orbits the sun. 2．根据文章第2段“Her curiosity led to the discovery of radium, which has helped save millions of lives through cancer treatment.”可推知，居里夫人的发现通过癌症治疗拯救了生命。故填Her discovery of radium has helped save millions of lives through cancer treatment. 3．根据文章第3段“Instead of just telling them facts, she encouraged them to grow their own.”可推知，这位乡村教师鼓励学生自己种植植物。故填She encouraged them to grow their own plants and explore. 4．根据文章第4段“This is because curiosity makes the brain more active and ready to learn.”可推知，好奇心使人更成功的原因是它让大脑更活跃、更愿意学习。故填Because curiosity makes the brain more active and ready to learn, helping them solve problems and adapt to new situations. 5．根据文章最后一段“Follow your curiosity—it might just lead you to something amazing.”可推知，作者建议我们追随好奇心。故填The author advises us to follow our curiosity instead of ignoring it. 根据短文内容回答下列问题 Curiosity is like a spark that lights up our desire to explore the unknown. In today’s fast-changing world, it’s more important than ever. From the latest AI technologies to space exploration, human curiosity drives innovation and progress. Take Elon Musk, for example. His curiosity about sustainable energy led to the creation of Tesla and SpaceX. He once said, “I want to understand why things are the way they are.” This mindset pushed him to revolutionize electric cars and rocket science. Similarly, young students around the world are using their curiosity to solve real-world problems. A 15-year-old girl in India invented a low-cost water purifier after seeing her community struggle with clean water. Her curiosity turned into a solution that now helps thousands. But curiosity isn’t just for scientists. It’s about asking questions and seeking answers. When you wonder how a smartphone works or why leaves change color, you’re using curiosity. Schools are now encouraging students to explore through projects like coding robots or growing plants. These activities help develop critical thinking and creativity. However, curiosity needs courage. Sometimes, the answers aren’t easy. Thomas Edison failed thousands of times before inventing the light bulb. He saw failure as a step forward, not a stop. This attitude is key: never stop wondering, even when things get tough. As we face challenges like climate change, curiosity will guide us to new solutions. Whether it’s finding renewable energy or curing diseases, the next big idea might start with a simple question. So keep asking, “Why?” and let your curiosity lead the way. The future belongs to those who dare to wonder. 1．Who is Elon Musk and what did his curiosity lead to? 2．What problem did the 15-year-old girl in India solve, and how? 3．How do schools encourage students to explore according to the passage? 4．How did Thomas Edison view failure? 5．What challenges can curiosity help us face according to the passage? 6．What is the author’s advice about curiosity in the passage? 【答案】1．Elon Musk is an entrepreneur.

It makes up about sixty percent of your body weight. Most of us get our water at a low price from the taps. But some people prefer bottled water, even though it costs more. Bottled water first appeared in the United States in the 1760s. A company called Jackson’s Spa sold bottled water. It said that the water could be good for people’s health. Since then, bottled water has become more and more popular worldwide. In 2019, for the first time, Americans drank more bottled water than soda. Why has bottled water become so popular? Well, this may have something to do with people’s worries about the purity (纯净) of tap water. According to one survey, 63 percent of Americans worried a lot about the safety of their drinking water. However, research suggests such worries are unnecessary. For most families, bottled water isn’t better than tap water. In fact, almost half of all bottled water comes from the tap. When it comes to taste, most of us can’t tell the difference. Once a blind taste test was done and only a third of the taste-testers were able to correctly pick out which one was from tap water. Making bottled water, however, requires lots of things. Plastic bottles are usually used only once before being thrown away. Besides, more water goes into the making of a bottle of water. One study found that companies usually use 1.39 litres (升) of water to make one litre of bottled water. Do you prefer bottled water to tap water? It’s time to change your mind! Bottled water is more expensive. However, it isn’t much better than the water you get from your kitchen tap. Task 1: Answer the questions: 1．Bottled water is cheaper than tap water, isn’t it? 2．When did bottled water first appear in America? 3．Why is bottled water popular with Americans? 4．Why was a blind taste test done? 5．How does the writer show the fact that more water goes into the making of a bottle of water? 6．What is the writer’s attitude towards tap water? Task 2: 7．Write more about the advantages of tap water or the disadvantages of bottled water in about 30 words. Read the passage and complete the tasks. (根据短文内容完成任务。) A new fleet of ocean-cleaning drones is being tested to remove plastic waste from the sea. These autonomous (自动的) devices use AI to detect and collect floating debris (碎片), helping to reduce the millions of tons of plastic polluting the oceans. The drones operate day and night, covering large areas more efficiently than human-led clean-up efforts. Traditional clean-up methods involve ships and nets, which are slow, expensive, and often harm marine life. The drones, however, are designed to avoid wildlife while targeting only plastic waste. Early trials show they can collect up to 100 kilograms of debris per day, making them a promising solution for large-scale ocean clean-up. One challenge is that strong ocean currents can push debris out of reach, making it harder for the drones to operate effectively. Dr. Hannah Lee, the project coordinator, says her team is improving the drones’ navigation systems to handle rough sea conditions. They are also developing ways to recycle the collected plastic into usable materials. If successful, these drones could play a key role in restoring marine ecosystems and protecting sea life. This technology offers hope for a cleaner, healthier ocean in the future. Task 1 Answer the questions 1．How do the drones identify plastic waste in the ocean? 2．Why are drones better than traditional clean-up methods? 3．How much debris can each drone collect daily? 4．What problem do strong ocean currents cause for the drones? 5．What aspect of the drones is Dr. Lee’s team improving?        Task 2 6．Explain how ocean-cleaning drones help marine life. (不超过30个词) Answer the questions（根据短文内容回答下列问题） Different from Earth Day which falls on April 22 every year, Earth Hour has been known for its “lights off” moment. On March 22, 2025, from 8:30 PM to 9:30 PM, millions turned off their lights to show they cared about the Earth. This year’s Earth Hour, with the theme (主题) “Create the Biggest Hour for Earth”, was even more important because it shared the same day as World Water Day. However, it’s not enough to have such an hour every year. What matters is how we can be kinder to the earth every day. Planet-friendly food You might not realize it, but the meat industry has a huge influence on forests around the world. Large numbers of trees are cut down to make space for soy (大豆) and other plants that are used to feed animals. Have a chat with your parents about going meat-free, even for a few days every week. Also, foods like vegetables, fruit and nuts are helping the planet. Go green and save money, too Electricity (电) produced by burning fuels like oil, coal and gas causes global warming and pollution. Ask your parents how they heat your home and suggest using green energy like wind or solar power (太阳能). Another tip is to remember to turn off the electricity whenever you leave a room. Cutting down on screen time is actually good for both your health and the earth. Waste Less, Help more Waste is a big problem! We’ve talked about saving electricity. What about food waste? Every year, 1.3 billion tonnes of food is wasted around the world. That’s one-third of the total amount, which can feed up to 1.26 billion people. Try to talk to your parents about buying a proper amount of food. More importantly, find some ways online for leftover food at home. 1．When did Earth Hour take place in 2025? 2．Why was Earth Hour 2025 especially important? 3．How does the meat industry negatively affect forests? 4．Why is electricity produced by burning fuels harmful to the environment? 5．One-third of the world’s food is wasted, isn’t it? 6．As teenagers, what can we do to contribute to Earth Hour and environmental protection beyond just turning off lights for one hour?      Nowadays water pollution is becoming an important problem. We can hear about water pollution from TV sometimes. A report shows that more than one third of the country’s industrial waste water flows directly into rivers and lakes. The water environment in most cities around the country is declining(下降). An official report from the Ministry of Environment Protection(环保总局 ) shows that among the investigated 131 rivers that flow through cities, 36 are severely(严重) polluted, and nearly 60 others polluted. Since the Songhua River benzene(苯) pollution incident in 2005, over 140 pollution cases have been reported. The Yellow River, an important water resource for North China, is suffering from serious pollution. Nearly 40 percent of its mainstream has been severely polluted. And situation is no better for the Huai River, in which the country has invested(投入) most. It is also a severely polluted river.    Water, like the air, is another basic substance(物质) of human life. But the fact is that more and more water is being polluted. The available drinking water is declining. Some factories are only busy developing their factories, without any thought of protecting the environment. They pour the waste water into rivers and oceans as they like. Although sometimes they are forbidden and punished, after that they will continue to do as usual because of money. In brief, it’s time for us to take steps to improve our living environment before it is too late. 1．What flows directly into rivers and lakes according to the first paragraph? 2．How many of the investigated 131 rivers are severely polluted? 3．When did the Songhua River benzene pollution incident take place? 4．Four rivers are mentioned in the passage, aren’t they? 5．Why will the factories continue to pour waste water into rivers? Answer the questions (根据短文内容回答下列问题)     It was 10 p.m. on a Wednesday night. Fourteen-year-old Li Gong sat at his desk and stared at a blank sheet of paper. Li had to write a 600-word book report and it was due the next day. The problem? He hadn’t read the book. Li opened an AI app on his computer and typed in “Book report, 600 words, The Old Man and the Sea.” In less than a minute, the boy had his book report. Several days later, Li was called into his teacher’s office. Unfortunately, his teacher was very familiar with computers and AI apps. One of the apps scanned (扫描) his students’ writing to detect cheating. Li had been caught! But his teacher was kind. Instead of punishing the boy, he explained that although AI apps were a helpful shortcut for some things, there was no shortcut to learning. Learning how to write well is valuable to understanding a subject and expressing your own ideas about it. An AI app depends on a collection of information that someone has uploaded onto a computer system. A specially trained algorithm (算法) processes the information to produce the type of writing someone might need. It’s useful for writing business emails, legal documents (法律文件) and even news reports, but it’s not useful for expressing your personal ideas and thoughts. Writing is the most difficult of all the language skills. You need to be good at grammar and have a good vocabulary. Writing also requires you to think clearly. For example, Li Gong was supposed to read Ernest Hemingway’s The Old Man and the Sea and find out what it was about. It’s the story of a poor fisherman who catches a big fish one day. It’s too big to put in his boat, so he drags it behind him in the water. When he reaches the shore, all that is left is the fish’s skeleton. It’s a sad story, but what does it all mean? If Li had read the book and written the book report, he would have learned a lot and had the satisfaction of expressing his own ideas about the story. That’s something AI cannot do. 1．Li Gong finished his book report on The Old Man and the Sea on his own, didn’t he? 2．How does an AI app produce a piece of writing? 3．What do you need to do in order to be able to write well? 4．Who wrote the book The Old Man and the Sea? 5．According to the author, what is AI unable to do? 6．Now that AI can “write”, do you think it is still necessary for students to learn how to write well? Give your reason(s). Kuakuaqun is social media chat groups that people pay a little money to join and are paid to show kindness, support and comfort to others in the group. The new chat groups have become popular with young people. According to media reports, the first such online praise group was formed by a few users of Douban, one of the major online social networks, for fun. However, the idea has caught on and praise-seeking chat groups have become popular among college students across the country. It was hard to understand Kuakuaqun at first. What kind of value do kind words have if I am paying someone to say them? Lin Yingying from Quanzhou described the groups as “a joke”, but also offered some insight (见解). “We rarely hear nice things in real life,” Lin said, “maybe we are not good at telling people...that we are not feeling well...” She thinks it is easier for people to share their problems online. Kuakuaqun doesn’t only exist in China. No matter where you come from, it is common to hear someone say, “You are not good enough.” There is a certain beauty in giving encouragement to others. Perhaps that is why so many young people have joined the groups. A reporter from Russia Today wrote about a post in which someone admitted that they woke up at 2 pm one day. One user replied, “You must care about your health very much as you sleep for so long, praise you.” That praise sounds hollow, but the humor doesn’t. Maybe that is the real value. A good joke can brighten anybody’s day. Experts have said that the popularity of Kuakuaqun reflects the users’ stressful, anxious and lonely mentalities (心态). It creates a positive and friendly environment for people that may help them get confidence again. 1．What is Kuakuaqun? 2．Where have praise-seeking chat groups become popular? 3．It was easy to understand Kuakuaqun at first, wasn’t it? 4．Why does Lin Yingying from Quanzhou think people share problems more easily online? 5．What does the popularity of kuakuaqun reflect according to experts? 6．Do you want to join Kuakuaqun? Why or why not? What did people from the New Stone Age look like? For a long time, nobody knew. But modern technologies have now showed us the faces of two men from that time. Last month, a group of Chinese researchers released the portraits (肖像) of these two men. They were based on their skulls. These head bones were discovered at the Yangshao Village site in Henan Province. The researchers believe the two men both lived near the Yellow River. One man likely lived around 5, 600 years ago, during the Yangshao culture. He was about 40 years old when he died. The other was around 50. He might have lived about 4, 000 years ago. This was the Longshan culture period. At present, there are no written records of these ancient people. The researchers collected lots of data from the skulls. They used the data to create 3D models of the men’s faces. Then, they studied populations with the closest genetic (基因的) background. This helped them to rebuild the muscles. Genetic studies also showed other features of the two men. These include their skin color and what their hair was like. “The project lets us know the faces of our ancestors,” said one of the researchers. “It also helps us learn something about the rich cultures of ancient society. ” 1．What did the researchers base the portraits of the two men on? 2．Where were the head bones of the two men discovered? 3．When did the man from the Yangshao culture likely live? 4．At present, there are no written records of these ancient people, are there? 5．How did the researchers rebuild the muscles of the two men’s faces? 6．What can we learn from this project according to the passage? 阅读文章回答问题 Curiosity: The Key to Great Discoveries Throughout history, curiosity has been the driving force behind some of the most important discoveries. Take Galileo Galilei, for example. As a young man, he was curious about the stars and planets. While others believed the Earth was the center of the universe, Galileo wondered if that was true. He built a telescope to observe the sky and found that the Earth orbits the sun—a discovery that changed science forever.   Another example is Marie Curie, who was curious about unknown elements. She spent years studying radioactive materials, even when many people thought it was a waste of time. Her curiosity led to the discovery of radium, which has helped save millions of lives through cancer treatment.   Curiosity isn’t just for famous scientists. It’s part of everyday life. A teacher in a small village noticed that her students were curious about plants. Instead of just telling them facts, she encouraged them to grow their own. The students began asking questions: Why do some plants need more water? How do they make food? Through exploring, they learned more than any textbook could teach.   In fact, research shows that curious people are more successful in life. They are better at solving problems and adapting to new situations. This is because curiosity makes the brain more active and ready to learn. When we’re curious, we pay more attention and remember information better.   So, the next time you wonder “why” or “how”, don’t ignore it. Follow your curiosity—it might just lead you to something amazing. 1．What did Galileo discover by observing the sky with a telescope?   2．How did Marie Curie’s curiosity help save lives?   3．What did the village teacher do to encourage her students’ curiosity?   4．Why are curious people more successful in life according to research?   5．What does the author advise us to do when we feel curious?   根据短文内容回答下列问题 Curiosity is like a spark that lights up our desire to explore the unknown.
