三、阅读单选（本大题共15小题，每小题2分，共30分）
A
Many people are welcoming artificial intelligence (AI). They use AI such as ChatGPT and Deepseek to produce text quickly. Some people find that helpful for school or work. Other AI tools like Doubao create images and even are able to talk with people. But AI isn’t always right. And it brings risks, especially if it is used incorrectly. We asked some students whether they think AI is good for society or not. They made strong points on both sides of the problem. Here are three of their answers. Which one do you agree with
Rime Lee, 13, Winnipeg, Manitoba, Canada
I believe AI can help in many areas. These include healthcare, education, robotics, and more. Some people might think students could use AI to get answers without thinking. But AI doesn’t just give students the answers directly. It can help them solve problems step by step. That’s a great way to learn.
Maren Altrup, 12. Springfield, Missouri
AI can be good for society in some ways, but it could also go wrong. With AI, it can be hard to know what is real and what is made-up. And students could cheat on their homework. This would not be good, because teachers will not know if students understand. Students could stop thinking for themselves and depend too much on AI.
Thomas McGibbon, 14, Pelham, New York
Artificial intelligence is good for society. Without it, some helpful websites wouldn’t exist. It’s also good because you might have a question but your parents don’t know the answer. Then you can ask AI. I know students can use artificial intelligence to cheat on tests or on their homework. But a lot of schools are able to block those websites so that students can’t cheat.
31．How many AI tools does this passage include
A．1. B．2. C．3. D．4.
32．What can people use AI tools to do
①produce text ②create images
③produce chatbots ④help with study or work

A．AI can help in many areas. B．AI can be good for society.
C．AI opens up new opportunities. D．Is artificial intelligence good for society
B
Recently, the world has been excited about a new AI model, DeepSeek-R1. It was developed by DeepSeek, a Chinese business in Hangzhou, Zhejiang Province. The new AI came out on Jan 20. In just one week, it beat OpenAI’s ChatGPT and became the top free app in Apple’s App Store.
The developers said that DeepSeek-R1 is as good at difficult tasks as other big models but needs less computing power (算力). It is also the cheapest of its kind and took only about 5.57 million US dollars (40.58 million yuan) to develop, while US businesses have had to spend much more money building similar AI models.
DeepSeek-R1’s success largely came from its special training method. Traditionally, AI is trained in two ways. One is Chain-of-Thought (CoT). In this way, AI learns to break problems into smaller and simpler steps. The other is Supervised Fine-Tuning (SFT). It works by showing AI lots of problems together with the right answers for it to find a pattern (模式). DeepSeek-R1, however, used Reinforcement Learning (RL) as the key method. In RL, AI learns by trying different things. It gets rewards for correct actions and gets punished for mistakes. For example, in a game, it gets points for picking up rubbish and loses points for breaking a glass. Over time, it works out the best solution (解决方法) all by itself.
In short, DeepSeek-R1 is great. This model shows that China is getting better at AI. DeepSeek-R1 tells us that new ideas can make AI grow, and it will help many parts of our life.
36．How does Paragraph 2 show that DeepSeek-R1 has a low cost
A．By giving an example. B．By listing the number.
C．By asking a question. D．By telling a story.
37．The underlined word “rewards” in Paragraph 3 probably means “________”.
A．困境 B．惩罚 C．成功 D．奖励
38．Which statement about DeepSeek-R1 is TRUE
A．It performs much worse than other large AI models on hard tasks.
B．It requires fewer computing resources than other big AI models.
C．It cost over 40 million US dollars to create.
D．It failed to rank high in Apple’s App Store at first.
39．Which is the structure of the passage
A． B． C． D．
40．What is the passage mainly about
A．The history of DeepSeek-R1. B．The developers of DeepSeek-R1.
C．The work of DeepSeek-R1. D．The introduction to DeepSeek-R1.
C
What Is Digital Literacy (数字素养)
In today’s fast-developing digital world, a new and necessary skill called “digital literacy” is becoming more and more important, especially for middle school students who use phones and computers every day. But what does this skill really mean
Digital literacy is not just about knowing how to turn on a phone or type on a computer. Instead, it includes three clear and key parts.

For example, when doing homework about science or history, students with good digital literacy can find useful and reliable information quickly on the Internet and check if it comes from trusted sources. They also know better than to share their private details on social media platforms like WeChat or TikTok.
Schools around the world are now starting to teach digital literacy courses to help students. This skill lets young people use technology in a safe and wise way, instead of being confused or harmed by it. As technology keeps growing, digital literacy will be even more necessary for everyone in the future.
41．What is NOT part of digital literacy according to the passage
A．Using search engines correctly B．Telling real news from fake news
C．Fixing broken computers by oneself D．Protecting personal online data

17．句意：我祖父过去常给朋友写信。
根据“letters”及后文“get a reply“，可知是写信，write letters to意为“给某人写信”，固定搭配。
18．句意：它又快又便宜。
这里在对比过去写信和现在发邮件/网上聊天，现在的方式“快”且“便宜”，下文“without paying不用花钱”，网络通讯成本低。

根据语境在线聊天免费，可知用without表示否定，表示“没有/不用”。

后文提到“了解他们正在做什么”，应是“查看”朋友圈。check有“查看”的意思，check his friends’ WeChat moments意为“查看朋友的微信朋友圈”。
25．句意：比如，一些学生花费太多时间玩游戏或者网上聊天。
spend time doing sth.意为“花费时间做某事”，play games是“玩游戏”，固定搭配。
26．句意：所以，我们需要以正确的方式使用科技。
前文说科技带来了一些问题，那么我们就需要用“正确的”（right）的方式使用科技。
27．句意：我们应该记住科技旨在帮助我们，而不是控制我们。
根据“not to control”可知，科技是为了“帮助”（help）我们，而不是控制。
28．句意：它是一个有用的工具，但我们应该知道何时关掉它并享受我们周围真实的世界。
but表示转折，它虽然有用但我们为了“enjoy real world”（享受真实的世界），应该知道何时停止使用，所以，“turn off“关掉”符合题意。
29．句意：谁知道未来什么将成为可能。
后文提到机器人、去月球等，可知事物会变得可能，“possible可能的”符合语境。
30．句意：无论发生什么，我们都应该准备好面对新世界。

33．根据第二段中“But AI doesn’t just give students the answers directly. It can help them solve problems step by step.”可知，人工智能不仅仅是直接给学生答案，还能帮助“他们”逐步解决问题，这里的“them”指代的是前一句提到的“students”。
34．根据Thomas McGibbon段落的首句“Artificial intelligence is good for society.”可知，他明确认为人工智能对社会有益，与选项C选项表述一致。
35．通读全文可知，文章首段中提出“We asked some students whether they think AI is good for society or not”，随后列举了三位学生对此问题的不同看法（有的支持，有的指出风险，有的支持但有条件）。选项D“Is artificial intelligence good for society ”最能概括文章关于AI利弊讨论的主题。

【导语】本文是一篇说明文，主要介绍中国深度求索公司研发的AI模型DeepSeek-R1，介绍它一经推出迅速走红，拥有算力需求低、研发成本低廉的优势，重点讲解其独特的强化学习训练方式，并点明该模型彰显了中国人工智能领域的发展进步。
【解析】36．第二段给出信息：“took only about 5.57 million US dollars (40.58 million yuan) to develop”，通过列出具体数字来说明DeepSeek-R1研发成本低。
37．第三段说明：“It gets rewards for correct actions and gets punished for mistakes”，rewards与后面的punished“惩罚”形成对比，做正确的事得到“奖励”，犯错则受到“惩罚”，因此rewards意为“奖励”。
38．第二段写明：“DeepSeek-R1 is as good at difficult tasks as other big models but needs less computing power.”，说明它相比其他大模型需要更少的算力资源。
39．文章第①段总起，引入DeepSeek-R1；第②段介绍模型优势；第③段讲解独特训练方法；第④段总结意义。属于总分总结构，对应A图示结构。

【导语】本文主要介绍数字素养的三大核心内容、日常应用以及学校开设相关课程的意义。
【解析】41．根据第二段内容可知，数字素养包括三部分：First, technical competence（如 using search engines... in a proper way）；Second, information evaluation（如 tell real news from fake）；Third, online safety（如 protecting your personal data）。选项A、B、D均在文中提及，而选项C“自己修理坏掉的电脑”并未包含在数字素养的定义中。
42．根据最后一段中“This skill lets young people use technology in a safe and wise way, instead of being confused or harmed by it.”可知，学校教授数字素养是为了让年轻人能够安全且明智地使用技术，而不是被其困扰或伤害。
43．第三段空缺处后紧接着列举了两个例子：一是做作业时查找可靠信息，二是在社交媒体上不分享隐私。这两个例子展示了数字素养在不同生活场景中的应用。选项B“数字素养出现在许多情境中”能很好地概括下文内容并引出例子。
