When Isaac Newton saw an apple fall from a tree, he didn’t ignore it. Instead, he felt 17 and asked, “Why does it fall down ” This question led him to 18 the theory of gravity. Similarly, Archimedes was curious about the water rising when he got into a bath. His 19 led to the discovery of buoyancy (浮力), which is still used in physics today.
In daily life, curiosity helps us learn better. A 2014 study 20 that curious people remember information 30% better than others. This is because curiosity makes the brain more 21 to new knowledge. For students, staying curious can 22 them to ask more questions and find answers on their own.

The Power of Curiosity
Curiosity is a powerful force that can drive people to achieve great things. It is the desire to know more, to explore, and to understand the world around us.
Throughout history, curious people have made amazing discoveries. For example, Galileo Galilei was curious about the stars and the planets. He used a telescope to observe the sky and made many important discoveries about the solar system. His curiosity changed the way people thought about the universe.
Curiosity can also lead to personal growth. When we are curious, we are more likely to learn new skills and gain new knowledge. We may try new hobbies, read different kinds of books, or meet new people. All these experiences can broaden our horizons and make us more well-rounded individuals.
In addition, curiosity can improve our relationships. When we are curious about others, we show that we care about them. We ask questions, listen to their stories, and try to understand their perspectives. This can help us build stronger connections with people.
However, curiosity needs to be balanced. We should not be overly curious about things that are none of our business, such as other people’s private lives. Also, we should use our curiosity in a positive way, not to cause harm or trouble.

In the past you could draw anything you wanted on a computer screen and then print it out on a piece of paper—a flat piece of paper. But imagine being able to print something that is three-dimensional—3D．Would you like to design an object, such as a cup or a toy, and then “print” it out Well, there is the technology to help you do this—to produce even a whole house!
3D printers might be the size of a suitcase or even a small room, depending on the object they are made to produce. You make a 3D design on your computer and send it to the printer. Inside the machine, the object you have designed is made as one object.
So how is this being used In medicine, 3D printing is often used to make teeth. The dentist takes a 3D image, something like a photo of the real tooth and a new one is printed in that exact shape. Then you might also want to print a mobile phone cover or a special pair of shoes.
Scientists are taking this even further. They have made a bicycle that just needs a chain and two tires (轮胎). Car parts have been made for a while, and now they are even making a body of a whole car!
But imagine how printing a whole house might help people build houses. A Chinese company has made houses using a giant 3D printer. They use a mixture that includes concrete (混凝土) and recycled building waste.
This is a good thing, as it helps the environment. They believe that their method of printing houses is cheaper, faster, less dusty and less noisy than the ordinary way that houses are built.
It seems that 3D printing technology will change our world, and China is leading the way.
41．3D________ enables you to “print” out many objects you design on your computer.
A．screen B．product C．paper D．technology
42．The size of a 3D printer might be________ according to the object they design.
A．changeable B．always small C．seldom big D．the same
43．In medicine, 3D printing is often used to print________ in the exact shapes.
A．dentists B．teeth
C．photos D．mobile phone covers
44．Scientists are taking this even further. Here “this” probably refers to “________”.
A．a pair of shoes B．the printing
C．a new bicycle D．a whole car
45．Which of the following can be the best title for this passage
A．Use the 3D printing technology to build houses.
B．China is now ready to produce 3D printers.
C．The 3D technology will change our world.
D．3D printing technology protects the environment.

六、短文语法填空（本大题共10小题，每小题1.5分，共15分）
阅读短文，根据上下文和首字母提示，填入适当的单词。
Every great discovery begins with a simple question. Scientists are naturally c 61 —they always ask “why ” or “how ”. For example, Isaac Newton became curious when he saw an apple f 62 from a tree. That moment led to his theory of gravity. Today, young inventors also use curiosity to s 63 real-world problems. One student created a device to detect water pollution using s 64 sensors. Another built a robot that helps elderly people. These projects show that even teenagers can make a d 65 . However, success doesn’t come easily. It takes p 66 , hard work, and the courage to fail. Most importantly, never stop a 67 questions. As Einstein once said, “I have no special talents. I am only p 68 curious.” So keep your mind open, stay curious, and remember: every big idea starts with a s 69 thought. The future belongs to those who dare to w 70 “What if… ”

56．take a walk/have a walk/go for a walk

【导语】本文是说明文。文章围绕“好奇心在科学领域的作用”展开，通过定义、举例 (牛顿的案例)、说明现实应用及补充条件 (需要耐心和毅力)，客观解释了好奇心对科学研究的重要性。
【解析】61．句意：科学家们天生好奇——他们总是问“为什么”或“怎么”。后文“they always ask “why ” or “how ”.”体现科学家天生“好奇的”，curious（好奇的）符合语境和首字母提示。
62．句意：例如，当艾萨克·牛顿看到一个苹果从树上掉下来时，他变得很好奇。牛顿发现万有引力的经典故事中，苹果是“正在掉落”的状态，用现在分词falling表过去正在发生的动作。
63．句意：如今，年轻的发明家也利用好奇心来解决现实世界的问题。结合“real-world problems”可知，solve（解决）是固定搭配“solve problems”（解决问题），符合语境。
64．句意：一名学生创建了一种使用智能传感器检测水污染的设备。检测水污染的传感器需具备“智能的”特性，smart（智能的）能精准捕捉污染信号，符合首字母和语境。
65．句意：这些项目表明，即使是青少年也能有所作为。“make a difference”是固定搭配，意为“产生影响/带来改变”，符合“青少年也能创造价值”的语境。
66．句意：成功需要坚持、努力以及敢于失败的勇气。后文强调“努力工作、勇于失败”，persistence（坚持）更贴合“持续努力”的语境；若侧重“耐心”，也可填patience，但persistence更准确。
67．句意：最重要的是，永远不要停止提问。“ask questions”是固定搭配，此处用动名词asking作宾语，意为“永远不要停止提问”。
68．句意：我只是充满激情。爱因斯坦原话是“I am only passionately curious”，此处结合首字母和语境，用副词passionately（充满激情地）修饰形容词“curious”，强调“对事物充满热情”。
69．句意：所以，保持开放的心态，保持好奇心，记住：每个大想法都始于一个小想法。呼应开头“Every great discovery begins with a simple question”，用small（小的）强调“大想法源于小念头”的逻辑。
70．句意：未来属于那些敢于思考“如果……怎么办？”的人。“wonder”意为“想知道/好奇”，“dare to wonder”表示“敢于好奇地思考”，符合“提出‘如果……会怎样？’”的语境。
71．例文
Dear Li Hua,
I totally understand how you feel. Schoolwork can sometimes seem never-ending and even crazy. But I think the problem is not learning itself, but our attitude towards it.
Remember our unit "Curious Minds" It taught us that curiosity is the key to making learning fantastic. Instead of just looking for the right answers, we should try to be curious about the questions. For example, when we study history, we can ask, "Why did this happen " This deepens our understanding and makes everything more interesting.
Here are two suggestions for you. First, try to connect what you learn in class to your daily life. Second, always find out something new about a topic you like. Learning is a journey, not a race. Just enjoy the process.
Hope you feel better soon!
Yours,
Zhang Ming
