Consider Isaac Newton, 1 curiosity about a falling apple led to the law of universal gravitation. Or Archimedes, who famously shouted “Eureka!” when he realized that the water level in his bath was connected to the volume of his body. These moments of insight did not happen by accident---they were the 2 of years of wondering, observing, and questioning. What makes these historical figures stand out is not just their intelligence, but their 3 willingness to ask “why” and “how.” They refused to accept the world 4 it was. They wanted to understand its underlying principles. This is the essence of curiosity: a deep, persistent desire 5 the unknown. In today’s world, curiosity is more important than ever. We are surrounded by information, 6 true understanding is often lacking. Curiosity helps us cut through the noise and seek out meaningful knowledge. It encourages us 7 beyond surface-level explanations and dig deeper. It gives us the courage 8 questions that others might consider foolish or unnecessary. Perhaps the greatest lesson we can learn from curious minds 9 history is this: curiosity is not a luxury-it is a necessity. It is the force that drives human progress, the spark that ignites innovation, and the light that 10 us through the darkness of ignorance. 1．A．who B．whose C．whom 2．A．result B．results C．resulted 3．A．unwaver B．unwavering C．unwaveringly 4．A．as B．like C．for 5．A．know B．to know C．knowing 6．A．but B．so C．and 7．A．look B．to look C．looking 8．A．ask B．to ask C．asking 9．A．from B．of C．in 10．A．guide B．guides C．guided 【答案】 1．B 2．A 3．B 4．A 5．B 6．A 7．B 8．B 9．C 10．B 【导语】本文通过讲述历史上艾萨克·牛顿、阿基米德等具有好奇心的人物的故事，阐述了好奇心在人类探索世界、推动进步等方面的重要作用，强调好奇心不是奢侈品而是必需品。 【详解】 1．句意：以艾萨克·牛顿为例，他对一个掉落的苹果的好奇心导致了万有引力定律的发现。 根据句子结构可知，此处是一个定语从句，先行词是Isaac Newton，从句中缺少定语来修饰curiosity，表示“……的”，所以要用关系代词whose，符合语境；who在从句中作主语或宾语，whom在从句中作宾语，均不符合语境。 2．句意：这些顿悟的时刻并非偶然发生——它们是多年好奇、观察和质疑的结果。 此处表示“多年好奇、观察和质疑的结果”，the result of为常用固定表达，result用单数形式符合语境，其余选项均不符合语境。 3．句意：使这些历史人物脱颖而出的不仅仅是他们的智力，还有他们坚定不移的、愿意询问“为什么”和“如何”的意愿。 此处需要一个形容词来修饰名词willingness，unwavering是形容词，意为“坚定不移的”，符合语境；unwaver是动词，unwaveringly是副词，均不符合语境。 4．句意：他们拒绝接受世界本来的样子。 accept...as...是固定搭配，意为“接受……作为……；认为……是……”，符合语境；like作介词时意为“像”，for意为“为了”，均不符合语境。 5．句意：这就是好奇心的本质：一种对了解未知的强烈而持久的渴望。 desire to do sth.是固定搭配，意为“渴望做某事”，所以此处要用动词不定式to know，符合语境；know是动词原形，knowing是动名词或现在分词形式，均不符合语境。 6．句意：我们被信息包围，但真正的理解往往缺乏。 前半句说我们被信息包围，后半句说真正的理解往往缺乏，前后句之间是转折关系，所以要用but，符合语境；so表示因果关系，and表示并列关系，均不符合语境。 7．句意：它鼓励我们超越表面层面的解释，深入挖掘。 encourage sb. to do sth.是固定搭配，意为“鼓励某人做某事”，所以此处要用动词不定式to look，符合语境；look是动词原形，looking是动名词或现在分词形式，均不符合语境。 8．句意：它给了我们勇气去问那些别人可能认为愚蠢或不必要的问题。 courage to do sth.是固定搭配，意为“做某事的勇气”，所以此处要用动词不定式to ask，符合语境；ask是动词原形，asking是动名词或现在分词形式，均不符合语境。 9．句意：或许我们可以在历史上这些充满好奇心的人物身上学到的最重要的道理是：好奇心不是奢侈品，而是必需品。 固定搭配in history表示“在历史上”，in 符合语境；from（来自）；of（……的）均不符。 10．句意：它是推动人类进步的力量，是点燃创新的火花，是指引我们穿过无知黑暗的光。 此处的that引导定语从句，先行词是the light，是单数，且在一般现在时的语境中，谓语动词要用第三人称单数形式guides，符合语境；guide是动词原形，guided是动词过去式或过去分词形式，均不符合语境。 能力综合实践5篇 一、请通读下面短文，掌握其大意，从每小题所给的三个选项中选出一个最佳答案。 The ocean is a mysterious world.

Today is my fiftieth birthday, but I look like a person of eighty-five. I have serious kidney (肾脏) problems because I don’t have enough water 1 . I’m afraid I don’t have much time left to live. I’m already one of the oldest people in this society. I remember when I 2 five years old, everything was very different. There were lots of trees in the park. I could enjoy a shower for half 3 hour. At that time, women all had beautiful hair. Now we have to shave (剃光) our heads to keep them clean without the use of water. I remember there were “Save Water” warnings in public places, but nobody 4 attention. We once believed that water would last forever. Now all the rivers and lakes are either dry 5 polluted. Water is much 6 than gold and diamonds. In the past, doctors advised me to drink eight glasses of water a day 7 healthy. Nowadays, I 8 only drink half a glass. Most people are weak and sick. When my son asks me about my childhood, I tell him about how pleasant it was to fish in the rivers and how healthy people were. 9 he asks, “Why is there no clean water now?” I feel guilty. I belong to those people who simply turned a blind eye to all the warnings.

But what exactly makes it so powerful? 1 recent studies, curiosity prepares the brain for learning. When we are curious about something, our brain enters a state 2 it is more ready to take in and retain information. This is 3 curious people tend to learn more effectively. However, curiosity is not a single, unchanging trait. It 4 in different forms at different ages. Babies show curiosity through sensory exploration---they touch, taste, and 5 everything they can reach. Preschoolers express curiosity by asking “why” questions endlessly. School children 6 their curiosity through more complex questioning and experimentation. Adults, 7 , often need to make a conscious effort to stay curious. The demands of daily life can dull our natural sense of wonder. The good news is that curiosity can be cultivated. We can train ourselves 8 more curious by asking open-ended questions, exploring new subjects, and embracing uncertainty. Schools can play a key role by creating learning environments 9 questioning is encouraged rather than discouraged. When we treat curiosity 10 a skill to be developed rather than a fixed trait, we open the door to lifelong learning and growth. 1．A．According B．According to C．According with 2．A．which B．where C．when 3．A．what B．how C．why 4．A．manifest B．manifests C．manifested 5．A．smell B．to smell C．smelling 6．A．express B．expresses C．expressed 7．A．however B．therefore C．otherwise 8．A．become B．to become C．becoming 9．A．which B．who C．where 10．A．as B．like C．for 【答案】 1．B 2．B 3．C 4．B 5．A 6．A 7．A 8．B 9．C 10．A 【导语】本文主要介绍了好奇心被称为智力成长的引擎，阐述了它在不同年龄段的表现形式，并指出好奇心是可以培养的，学校在其中能发挥关键作用。 【详解】 1．句意：根据最近的研究，好奇心能让大脑为学习做好准备。 根据固定搭配和语法可知，表示“根据”需要用“According to”。According单独使用不符合语法；According with为错误搭配，均不符合语境；According to是固定短语，因此According符合语境。 2．句意：当我们对某事感到好奇时，我们的大脑会进入一种状态，在这种状态下它更容易接受和保留信息。 根据句子结构可知，此处是定语从句，先行词是抽象名词“state”。which在从句中作主语或宾语，when指代时间，均不符合语境；where作为关系副词引导定语从句，修饰抽象名词表示“在这种状态下”，符合语境。 3．句意：这就是为什么好奇的人往往学得更有效。 根据上下文逻辑可知，前文提到好奇心让大脑为学习做好准备，这里是得出结论。what和how均不符合因果逻辑，均不符合语境；why引导表语从句，意为“这就是为什么……”，符合语境。 4．句意：它在不同年龄段以不同的形式表现出来。 根据主语“It”和上下文时态可知，此处描述的是普遍事实，需用一般现在时的第三人称单数形式。manifest为原形，manifested为过去式，均不符合语境；manifests为主谓一致的第三人称单数形式，符合语境。 5．句意：婴儿通过感官探索表现出好奇心——他们触摸、品尝和闻所有他们能接触到的东西。 根据并列结构可知，空格处需要填一个动词原形与“touch”、“taste”并列。to smell和smelling不符合并列结构，均不符合语境；smell为动词原形，符合语境。 6．句意：学龄儿童通过更复杂的提问和实验来表达他们的好奇心。 根据主语“School children”和上下文时态可知，此处需用一般现在时的动词原形。expresses为第三人称单数形式，expressed为过去式，均不符合语境；express为动词原形，符合语境。 7．句意：然而，成年人通常需要做出有意识的努力来保持好奇心。 根据上下文逻辑可知，前文提到孩子表现好奇心很自然，后文说成年人需要刻意努力，此处表示转折。therefore和otherwise不符合转折逻辑，均不符合语境；however意为“然而”，符合语境。 8．句意：我们可以通过问开放式问题等训练自己变得更好奇。 根据固定搭配可知，“train sb. to do sth.”意为“训练某人做某事”，此处需用动词不定式作补语。become和becoming不符合该搭配，均不符合语境；to become符合语境。 9．句意：学校可以通过创造鼓励提问的学习环境来发挥关键作用。 根据句子结构可知，此处是定语从句，修饰表示环境的先行词“learning environments”。which在从句中不作状语，who指代人，均不符合语境；where表示“在这些环境中”，符合语境。 10．句意：当我们把好奇心看作一种需要培养的技能而不是一种固定的特质时，我们就打开了终身学习和成长的大门。 根据固定搭配可知，“treat... as...”意为“把……当作……”。like和for不符合该固定搭配，均不符合语境；as符合语境。 四、请通读下面短文，掌握其大意，从每小题所给的三个选项中选出一个最佳答案。 “What if?” These two simple words have launched a thousand ships, inspired countless inventions, and changed the course of human history. They represent curiosity in its purest form—the willingness to imagine possibilities beyond the present reality. 1 the story of human progress is, in many ways, the story of “what if.” Consider the Wright brothers. 2 others saw birds flying and thought nothing of it, they asked, “What if we could fly too?” This question led them to years of experimentation, countless failures, and ultimately, the first powered flight. Or consider Marie Curie, 3 asked, “What if there are elements we haven’t discovered yet?” Her curiosity led to the discovery of radium and polonium, 4 revolutionized science and medicine. But “What if?” is not just for scientists and inventors. It is a question that 5 all of us, in our daily lives. What if I tried a different approach to this problem? What if I learned a new skill? What if I challenged my own assumptions? These questions open doors 96 we didn’t know existed. The power of “What if?” lies in its ability to free us from the constraints of conventional thinking. It invites us 6 the world with fresh eyes. It gives us permission to be wrong, to fail, and to try again. In a world that often rewards certainty and punishes uncertainty, asking “What if?” is an act of courage. So 7 you find yourself stuck in a rut, ask “What if.” Let your mind wander into the realm of possibility. You never know 8 it might lead you. As the poet Mary Oliver once wrote, “Tell me, what is it you plan to do with your one wild and precious life?” Perhaps the answer begins with two simple words: “What 9 ?” 1．A．So B．But C．For 2．A．When B．While C．Because 3．A．which B．who C．whom 4．A．that B．which C．what 5．A．belong to B．belongs to C．belonged to 6．A．where B．which C．who 7．A．see B．to see C．seeing 8．A．whenever B．whatever C．however 9．A．what B．how C．where 10．A．unless B．until C．if 【答案】 1．A 2．B 3．B 4．B 5．B 6．B 7．B 8．A 9．C 10．C 【导语】本文主要讲述了“假如会怎样”这一简单问题所蕴含的好奇心力量，它推动了人类进步，并鼓励我们在日常生活中勇于探索可能性。 【详解】 1．句意：因此，人类进步的故事在很多方面就是“假如会怎样”的故事。 根据上文提到该短语改变了历史，此处表结论，用So“所以”。But表转折，For表原因，均不符。 2．句意：当别人看到鸟儿飞翔却不以为然时，他们却问“如果我们也能飞会怎样？” 此处表示前后对比，While意为“然而”，符合语境。When仅表时间，Because表因果。 3．句意：或者想想玛丽·居里，她问道“如果还有我们没有发现的元素会怎样？” 先行词Marie Curie是人，且在从句中作主语，用who。which指物，whom作宾语。 4．句意：她的好奇心促成了镭和钋的发现，这彻底革新了科学与医学领域。 逗号后是非限制性定语从句，指代物，用which。that不能引导非限制性定语从句。 5．句意：这是一个属于我们所有人的问题。 先行词question是单数，时态为一般现在时，谓语用belongs to，意为属于。 6．句意：这些问题打开了我们不知道存在的门。 先行词是doors，指物，在从句中作existed的主语，用which。where表地点状语，who表人。 7．句意：它邀请我们用新的眼光看世界。 invite sb. to do sth.是固定搭配，意为“邀请某人做某事”，应用动词不定式to see。 8．句意：所以无论你何时发现自己陷入困境，问问“假如会怎样”。 引导时间状语从句，表示“每当”，用whenever。 9．句意：你永远不知道它会引领你去哪里。 lead sb. 后接方向或地点，where符合语境。what指事物，how指方式，均不符。 10．句意：也许答案始于两个简单的词：“假如会怎样？” 全文主题短语为What if，意为“假如怎样”。 五、请通读下面短文，掌握其大意，从每小题所给的三个选项中选出一个最佳答案。 The Internet has made knowledge more accessible than ever before.

Curiosity can bring new discoveries. Benjamin Franklin is a great example. He had a deep curiosity 1 the nature of electricity. He did lots of research trying 2 it. Once, he flew a kite during a storm without realizing its danger. His curiosity led him 3 the lightning rod. This invention protects buildings from lightning. Curiosity can also make people 4 brave. Just look at Wan Hu, the Ming Dynasty pioneer of space exploration. He showed such great interest in space that he invented a “flying chair”! Although he lost his life 5 he was testing this invention, his curiosity gave future explorers ideas. People 6 a lot from his courage since then, and have created much 7 ways to explore space. But curiosity is more than just taking risks. It also drives people towards certain goals. Zhang Heng, 8 ancient Chinese scientist and inventor, was eager to know about the world: how did everything in the world move? He spent years 9 the sky and the earth. Finally, he drew China’s first star map, and invented the first earthquake detector. A curious man won’t discover a new world 10 he tries to know what is going on through a keyhole.

Without water, no life 1 exist. Unfortunately, the world is running out of clean, fresh water. It’s important to learn how to save water, but where should we start? First, we need to be aware 2 the problem of water shortages and understand what causes them. This weekend, my class plans 3 a mountain village and carry out a water-saving survey. We will check every tap and pipe (管道). As soon as we 4 a leak (裂缝), we will record it and report it to the water company. Many similar villages 5 by water shortage in recent years. Local families often have limited clean water for daily use. Leaks caused by old pipes and taps have become 6 serious problem. Our teacher also reminds us 7 waste even a drop of clean water. We should think 8 before pouring water down the drain (下水道). For example, we can pour the water used to wash fruit and vegetables 9 our flower pots instead of letting it go down the drain. I hope more people will develop good water-saving habits. Future generations will thank 10 for protecting this valuable resource. 1．A．can B．might C．must 2．A．of B．at C．from 3．A．visit B．to visit C．visiting 4．A．found B．will find C．find 5．A．have been troubled B．are troubled C．are being troubled 6．A．a B．an C．the 7．A．to not B．not to C．don’t to 8．A．two B．second C．twice 9．A．into B．to C．for 10．A．we B．ours C．us 二、请通读下面短文，掌握其大意，从每小题所给的三个选项中选出一个最佳答案。 Digital life has become an inseparable part of modern society. From the moment we wake up 1 we go to bed, we are surrounded by digital devices. We check our phones first thing in the morning. We use navigation apps 2 our way to work. We communicate with colleagues through email and messaging apps. We stream videos for entertainment in the evening. This constant connectivity has 3 our lives more convenient, but it has also raised new challenges. One of the biggest challenges is information overload. We are 4 with more information than we can process. This can lead to stress and anxiety. Another challenge is the loss of privacy. Every click, every search, every 5 we make is tracked and recorded. Our personal data has become a valuable commodity. 6 , we cannot simply reject digital technology. It has become essential for work, education, and social connection. The solution lies in 7 digital literacy. We need to teach people how to use technology effectively and safely. We need to help them distinguish reliable information 8 misinformation. We need to encourage them to take breaks from screens and 9 in real-world activities. Ultimately, the goal is not to escape digital life 10 to master it. When we achieve that, we can truly enjoy the best of both worlds. 1．A．when B．until C．after 2．A．find B．to find C．finding 3．A．make B．makes C．made 4．A．bombard B．bombarding C．bombarded 5．A．move B．moving C．moved 6．A．However B．Therefore C．Besides 7．A．improve B．improving C．improved 8．A．and B．or C．from 9．A．engage B．to engage C．engaging 10．A．and B．but C．or 三、请通读下面短文，掌握其大意，从每小题所给的三个选项中选出一个最佳答案。 In his famous speech, Dr Gu shared a powerful message: curiosity is not just a nice-to-have quality — it is essential for success in almost every field. To support this view, he 1 several compelling pieces of evidence. First, he referred to a 2014 study 2 participants were asked to rate their curiosity about certain questions. The results showed that people 3 were highly curious about a fact were 30% more likely to remember it an hour later. This suggests that curiosity enhances memory 4 a biological level. Second, Dr Gu cited an experiment involving magic tricks. Participants were asked 5 their own magic tricks after learning about Harry Houdini’s famous elephant disappearance. The more curious group 6 up with significantly more creative ideas than the less curious group. This demonstrates that curiosity fuels creativity. Third, Dr Gu shared real-life examples of 7 curiosity shaped successful careers. Jeff Armstrong’s childhood curiosity about cars led him 8 engineering.

This is 1 most of the water is either too salty or locked in ice. As the global population continues to grow, the demand for fresh water 2 rapidly. Many scientists warn that water shortage will be one of the 3 problems in the coming decades. However, the situation is not hopeless. Technology 4 us new ways to deal with this challenge. For example, desalination (海水淡化) plants can turn salt water into fresh water. But this process requires a lot of energy and 5 a lot of money. Another solution is to improve water efficiency. In many places, water is wasted 6 old pipes or careless habits. Fixing these problems can save huge amounts of water. But technology alone is not enough. Education plays 7 important role. When people understand 8 valuable water is, they are more likely to save it. Schools should teach students about the water cycle and the importance of protecting water resources. Governments should also make laws to prevent water pollution. 9 everyone works together, we can ensure that future generations will have enough clean water.

Consider Isaac Newton, 1 curiosity about a falling apple led to the law of universal gravitation. Or Archimedes, who famously shouted “Eureka!” when he realized that the water level in his bath was connected to the volume of his body. These moments of insight did not happen by accident---they were the 2 of years of wondering, observing, and questioning. What makes these historical figures stand out is not just their intelligence, but their 3 willingness to ask “why” and “how.” They refused to accept the world 4 it was. They wanted to understand its underlying principles. This is the essence of curiosity: a deep, persistent desire 5 the unknown. In today’s world, curiosity is more important than ever. We are surrounded by information, 6 true understanding is often lacking. Curiosity helps us cut through the noise and seek out meaningful knowledge. It encourages us 7 beyond surface-level explanations and dig deeper. It gives us the courage 8 questions that others might consider foolish or unnecessary. Perhaps the greatest lesson we can learn from curious minds 9 history is this: curiosity is not a luxury-it is a necessity. It is the force that drives human progress, the spark that ignites innovation, and the light that 10 us through the darkness of ignorance. 1．A．who B．whose C．whom 2．A．result B．results C．resulted 3．A．unwaver B．unwavering C．unwaveringly 4．A．as B．like C．for 5．A．know B．to know C．knowing 6．A．but B．so C．and 7．A．look B．to look C．looking 8．A．ask B．to ask C．asking 9．A．from B．of C．in 10．A．guide B．guides C．guided 能力综合实践5篇 一、请通读下面短文，掌握其大意，从每小题所给的三个选项中选出一个最佳答案。 The ocean is a mysterious world. It covers more than 70% of the Earth’s surface, yet we know 1 about it than we know about the surface of the Moon. The ocean is home to millions of species, many of 2 have not even been discovered yet. It also provides us with food, medicine, and even the air we breathe. In fact, more than half of the oxygen (氧气) on Earth 3 by the ocean. But the ocean is in danger. Pollution, overfishing (过度捕捞) and climate change are 4 great harm to it. Millions of tons of plastic waste 5 into the ocean every year. This plastic kills marine animals and pollutes the water. Overfishing has reduced many fish populations to dangerously low levels. And climate change is making the ocean warmer and more acidic (酸性的), 6 is bad for coral reefs (珊瑚礁) and other marine life. We must take action now 7 the ocean. Governments should make stricter laws to control pollution and overfishing. Companies should find 8 ways to produce and transport goods without polluting the ocean. And each of us can also help.

Today is my fiftieth birthday, but I look like a person of eighty-five. I have serious kidney (肾脏) problems because I don’t have enough water 1 . I’m afraid I don’t have much time left to live. I’m already one of the oldest people in this society. I remember when I 2 five years old, everything was very different. There were lots of trees in the park. I could enjoy a shower for half 3 hour. At that time, women all had beautiful hair. Now we have to shave (剃光) our heads to keep them clean without the use of water. I remember there were “Save Water” warnings in public places, but nobody 4 attention. We once believed that water would last forever. Now all the rivers and lakes are either dry 5 polluted. Water is much 6 than gold and diamonds. In the past, doctors advised me to drink eight glasses of water a day 7 healthy. Nowadays, I 8 only drink half a glass. Most people are weak and sick. When my son asks me about my childhood, I tell him about how pleasant it was to fish in the rivers and how healthy people were. 9 he asks, “Why is there no clean water now?” I feel guilty. I belong to those people who simply turned a blind eye to all the warnings.

But what exactly makes it so powerful? 1 recent studies, curiosity prepares the brain for learning. When we are curious about something, our brain enters a state 2 it is more ready to take in and retain information. This is 3 curious people tend to learn more effectively. However, curiosity is not a single, unchanging trait. It 4 in different forms at different ages. Babies show curiosity through sensory exploration---they touch, taste, and 5 everything they can reach. Preschoolers express curiosity by asking “why” questions endlessly. School children 6 their curiosity through more complex questioning and experimentation. Adults, 7 , often need to make a conscious effort to stay curious. The demands of daily life can dull our natural sense of wonder. The good news is that curiosity can be cultivated. We can train ourselves 8 more curious by asking open-ended questions, exploring new subjects, and embracing uncertainty. Schools can play a key role by creating learning environments 9 questioning is encouraged rather than discouraged. When we treat curiosity 10 a skill to be developed rather than a fixed trait, we open the door to lifelong learning and growth. 1．A．According B．According to C．According with 2．A．which B．where C．when 3．A．what B．how C．why 4．A．manifest B．manifests C．manifested 5．A．smell B．to smell C．smelling 6．A．express B．expresses C．expressed 7．A．however B．therefore C．otherwise 8．A．become B．to become C．becoming 9．A．which B．who C．where 10．A．as B．like C．for 四、请通读下面短文，掌握其大意，从每小题所给的三个选项中选出一个最佳答案。 “What if?” These two simple words have launched a thousand ships, inspired countless inventions, and changed the course of human history. They represent curiosity in its purest form—the willingness to imagine possibilities beyond the present reality. 1 the story of human progress is, in many ways, the story of “what if.” Consider the Wright brothers. 2 others saw birds flying and thought nothing of it, they asked, “What if we could fly too?” This question led them to years of experimentation, countless failures, and ultimately, the first powered flight. Or consider Marie Curie, 3 asked, “What if there are elements we haven’t discovered yet?” Her curiosity led to the discovery of radium and polonium, 4 revolutionized science and medicine. But “What if?” is not just for scientists and inventors. It is a question that 5 all of us, in our daily lives. What if I tried a different approach to this problem? What if I learned a new skill? What if I challenged my own assumptions? These questions open doors 96 we didn’t know existed. The power of “What if?” lies in its ability to free us from the constraints of conventional thinking. It invites us 6 the world with fresh eyes. It gives us permission to be wrong, to fail, and to try again. In a world that often rewards certainty and punishes uncertainty, asking “What if?” is an act of courage. So 7 you find yourself stuck in a rut, ask “What if.” Let your mind wander into the realm of possibility. You never know 8 it might lead you.
