完形填空（用所给单词正确形式填空）
The Ministry of Education（教育部） has made an important announcement. It says students aren’t allowed to directly copy answers made by AI（人工智能） for their homework. This new rule is to help students think for themselves and improve their __1___(create) skills.

Many students these days use AI to help with their homework. AI can give quick answers, but using it too much can stop students from learning properly and___2___(think) critically. By just copying AI answers, students don't really understand the problems or learn how to solve them on their own.
完形填空（用所给单词正确形式填空）
The Ministry ___3____(want) homework to be a way to see how well students understand and use what they've learned. Teachers are asked to design homework that makes students think __4____(deep) and discover new things. This will help students remember what they__5___( learn) and also make them more creative and able to solve problems.

Parents and teachers should guide students to use AI in a good way. They should encourage students to see AI ___6___a tool to help their learning, not as a way to avoid doing their own work.
完形填空（用所给单词正确形式填空）
答案解析（导语：文章内容是关于近来教育部发文不允许学生直接复制AI答案完成作业）
1. 此空所在句的句意为“这项新规定是为了帮助学生独立思考，提高他们的_____技能”。create为动词，意思是“创造”，其形容词形式为creative，意为“有创造力的”，为形容词作定语修饰名词skills，表示“有创造力的技能”。故此空应填creative。
2. 此空所在句的句意为“AI可以快速给出答案，但过度使用它会阻止学生_____和批判性思维”。“stop sb from doing sth”为固定搭配，意思是“阻止某人做某事”，其实前面已经有learning，所以此空应填动名词thinking，这两个词是并列的，表示“阻止学生正确学习和批判性思维”。
3. 分析句子结构可知，此空为主句的谓语动词。主语为The Ministry，是第三人称单数，且全文为一般现在时，所以谓语动词要用一般现在时的第三人称单数形式wants，表示“教育部希望作业是一种方式来观察学生如何很好地理解和运用他们所学的知识”。故此空应填wants。
完形填空（用所给单词正确形式填空）
4. 分析句子结构可知，think是动词，deep为形容词，意思是“深的”，修饰动词用副词，其副词形式为deeply，意为“深深地”，所以此空应填deeply，表示“老师被要求设计作业来让学生深入思考并发现新事物”。
5. 根据上下文，教育部要求老师设计的作业要让学生深入思考并能发现新东西，“这将帮助学生记住他们（已经）学到的东西”。属于现在完成时，所以填have learned.
6. 此空所在句的句意为“他们应该鼓励学生把AI看作一个帮助他们学习的工具，而不是避免做自己的作业的一种方式”。“see…as…”为固定搭配，意思是“把……看作……”，所以此空应填介词as，表示“把AI看作一个帮助他们学习的工具”。另外，后面“not as a way to ···”也是一个提示，所以看上下文来理解很重要。故此空应填as。
选词填空（每个单词只能用一次，有两个多余的）
strong，from，ability， mistakes ，better，
incorrect，grow，part，keep, called，weak, correct
Artificial Intelligence( AI,人工智能 ), often _____1 as AI, is a technology that lets machines act like humans. AI cannot think like us, but it can learn ____2 data and perform tasks. For example, AI can recommend movies you might like or help answer questions online.
A big reason AI is useful is its _____3 to get smarter. By studying lots of information, AI can find answers and correct______4 . When you talk to a chatbot(聊天机器人), it uses your words to give _______5 answers later.
选词填空（每个单词只能用一次，有两个多余的）
But AI isn’t always right. If the data is wrong, AI’s results might be_______ 6 or confusing. Scientists say we need to use good data to teach AI fairly.
In the future, AI may change jobs. It could help farmers ______7 food or teachers check homework. Still, some fear AI might become too ______8 and control important things.
Today, AI is already a_____ 9 of our world. It’s in phones, games, and apps. Learning about AI helps us use it wisely.To make AI better, we should _____10 studying its uses and fix problems carefully.
选词填空（每个单词只能用一次，有两个多余的）
答案及解析(导语：此文是关于当前热门的人工智能（AI）)
1. called - 解析：此题考查被动语态，此句表达的是“人工智能通常被称为AI”，因此需要用过去分词“called”作为被动语态的一部分，表示“被叫做”。
2. from - 解析：此题考查短语learn from,根据句意“AI可以从数据中学习”，因此填“from”，所以日常短语的熟练很重要。
3. ability - 解析：此题考查上下文理解。句子中提到“AI变得更聪明的一个重要原因”，是它拥有这样的“ability”（能力）。
4. mistakes - 考查上下文理解能力：前文提到AI可以“找到答案”，后文与之并列的动作应是“纠正错误”，因此填“mistakes”（错误）。
5. better - 解析：根据句意“当你和聊天机器人交谈时，它会利用你的话给出better更好的答案”。
选词填空（每个单词只能用一次，有两个多余的）
6. incorrect - 解析：上下文理解。前文提到“但如果数据是错误的”，则AI的结果可能是“不正确的”，因此填形容词“incorrect”。

7. grow - 解析：根据句意“AI可以帮助农民种植食物”，可知此处需要动词“grow”（种植）。

8. strong - 解析：句子中提到“一些人担心AI可能变得过于强大而控制重要的事情”，

9. part - 解析：词组a part of 根据句意“今天，AI已经成为我们世界的一部分”，可知此处需要名词“part”（部分）。

10. keep - 解析：keep doing 的用法，句子中提到“为了使AI更好，我们应该继续研究它的用途并仔细解决问题”，因此需要用动词“keep”（继续）来表示这种持续性的动作。

A company China has introduced an exciting new tool called DeepSeek, which uses artificial intelligence (AI) to help people search for information more effectively. Unlike traditional search engines, DeepSeek focuses on understanding what users really need, even if their questions are complex or unclear.
Developed by Chinese AI experts, DeepSeek can analyze massive amounts of data quickly. For example, if you ask, "Why is the sky blue " it doesn’t just list websites—it explains the science in simple terms. This makes it especially useful for students, researchers, and anyone looking for reliable answers.
阅读理解1
One of DeepSeek’s coolest features is its ability to understand natural language. This means you can type questions the way you speak, like "What’s the best way to learn math " instead of using short keywords. The AI also recognizes synonyms, so searching for "big cities in China" and "large Chinese cities" will give similar results.
DeepSeek isn’t limited to text. It can search images, videos, and even audio files. Imagine uploading a photo of a plant and asking, "What species is this "—DeepSeek can identify it! However, some people worry about privacy, as the tool collects data to improve its AI.
阅读理解1
China’s investment in AI tools like DeepSeek shows its commitment to leading in technology. While it’s already popular in education and business, its creators aim to make it a global tool someday.
What is DeepSeek’s main purpose
A. To replace human teachers.
B. To improve how people search for information.
C. To create social media content.
D. To design video games.
How is DeepSeek different from traditional search engines
A. It uses fewer keywords.
B. It focuses on understanding natural language.
C. It only works in Chinese.
D. It avoids explaining scientific topics.

3.What can DeepSeek do with images
A. Edit them for social media.
B. Identify objects or species in photos.
C. Create new videos from images.
D. Print them on paper.
4.What concern is mentioned about DeepSeek
A. It is too slow.
B. It requires expensive devices.
C. It collects user data.
D. It cannot answer simple questions.
5.What goal do DeepSeek’s creators have for the future
A. To limit its use to China.
B. To make it popular worldwide.

Elon Musk’s （埃隆·马斯克） company, SpaceX, is changing how humans explore space. Since its start in 2002, SpaceX has focused on making rockets reusable(重复利用) and affordable, aiming to one day send people to live on Mars. A major project is the Starship, a huge spacecraft designed for long trips to the Moon, Mars, and other planets.
One of SpaceX’s coolest ideas is the "chopstick" method for catching rockets. Instead of letting rocket boosters fall into the ocean, SpaceX uses two giant arms (like chopsticks) on a tower to grab them mid-air. This helps reuse the boosters quickly, saving time and money. Though it was tricky at first, recent tests show this method works!
阅读理解2
SpaceX also created the Raptor engine, which uses cleaner fuels like liquid methane and oxygen. This makes it better for the environment than older rocket engines. Another project, Starlink, uses thousands of small satellites to provide fast internet worldwide—even in remote areas.
However, some people criticize SpaceX. They say focusing on Mars might ignore Earth’s problems like climate change. Others worry about too many satellites causing space junk. Still, SpaceX’s achievements prove that human space technology keeps improving. As Musk says, "Life needs to spread beyond Earth," and SpaceX is working hard to make that happen.

In 2024, China successfully launched the Shenzhou-20 spacecraft（神舟二十号）, marking another milestone in its rapidly growing space exploration efforts. The mission, which carried three astronauts to the Tiangong Space Station, focused on upgrading the station’s systems and conducting experiments in microgravity. This launch highlights China’s commitment to becoming a leading force in space technology.
One major breakthrough of the Shenzhou-20 mission is the use of advanced robotics. Astronauts deployed small repair robots outside the station to fix equipment without risky spacewalks. Additionally, the spacecraft used a new reusable rocket engine, cutting costs and reducing space debris（碎片）. These innovations show China’s focus on sustainable and safe space exploration.
阅读理解3
China’s space program has also expanded international cooperation. For example, the Tiangong station now hosts experiments from scientists in countries like Italy and Pakistan. Moreover, China plans to launch a joint mission with Russia to explore the Moon’s south pole by 2030. These partnerships aim to share knowledge and promote peace in space.
Looking ahead, China aims to build a lunar research base and send astronauts to Mars by the 2040s. While challenges remain, such as radiation protection and long-term life support, Shenzhou-20’s success proves China’s ability to tackle complex space missions. As one engineer said, “Every launch brings us closer to the stars.”
