【时文阅读】3. DeepSeek（阅读理解+语法填空+书面表达） Chinese AI Model DeepSeek-R1 Stuns the World January 20, 2025, a Chinese tech company named DeepSeek made a new AI called DeepSeek-R1. This smart program can solve math problems, write code, and answer questions like top models such as OpenAI’s GPT-4o, but it costs much less to build. The team spent only $5.58 million (1/70 of OpenAI’s cost) and used 2,048 computer chips for two months. This shows that good ideas can beat big money. DeepSeek-R1 learns by trying many times and getting better, like how students practice maths. Other AIs need lots of prepared examples, but R1 improves by itself. For example, in a global math test, it got 79.8% right, slightly higher than OpenAI’s model. A simple version of R1 can even run on low-cost computers, helping schools and small companies. DeepSeek-R1 is free to use and change. On its first day online, over 19,000 programmers worldwide started projects to study it. A German scientist said experiments with R1 cost $10 instead of $300 with other AIs. Even Meta (a famous U.S. tech company) top scientist said, “This kind of free AI could change the world.” U.S. tech companies are worried. Meta plans to spend $65 billion more on AI research. Experts say China is catching up fast. A report in 《Nature》magazine called R1 a “big step forward”, proving that smart ideas beat expensive tools. As a DeepSeek engineer said, “We want AI to be a friend, not something only rich people can use.” With R1, China shows the world that great things come from new ideas and hard work, not just money. 中国AI模型DeepSeek-R1震惊世界 2025年1⽉20⽇，中国科技公司深度求索（DeepSeek）研发出名为DeepSeek-R1的新型⼈⼯智能。这款智能程序能解决数学题、编写代码、回答问题，性能媲美OpenAI的 GPT-4o等顶尖模型，但开发成本低得多。团队仅花费558万美元（约为OpenAI成本的1/70），使⽤2048块计算机芯⽚耗时两⽉完成训练。这证明：好创意可以战胜巨额资 ⾦。 DeepSeek-R1通过“反复尝试、逐步改进” 的⽅式学习，就像学⽣练习数学题⼀样。其他AI需要⼤量标注范例，但R1能⾃主提升。例如，在⼀项全球数学测试中，它以 79.8%的正确率略胜OpenAI模型。R1的简化版本甚⾄能在低成本计算机上运⾏，助⼒学校和⼩型企业。 DeepSeek-R1免费开放使⽤与修改。上线⾸⽇，全球超过1.9万名程序员启动相关研究项⽬。⼀位德国科学家表⽰，⽤R1做实验仅需10美元，⽽其他AI要花费300美元。 连美国科技巨头Meta的⾸席科学家也称赞：“这种免费AI可能改变世界。” 美国科技公司倍感压⼒。Meta宣布追加650亿美元AI研发预算。专家认为中国正在快速追赶。《⾃然》杂志评价R1是“重⼤进步”，证明智慧创意能战胜昂贵⼯具。 正如⼀位深度求索⼯程师所说：“我们希望AI成为所有⼈的朋友，⽽⾮富⼈专属。” 通过R1，中国向世界展⽰：伟⼤的成就源于创新思维与⾟勤努⼒，⽽不仅仅是⾦钱。 本文重点单词和短语总结 programmers /prəʊˈɡræmərz/ n. 程序员（编写计算机程序的⼈） low-cost /loʊkɒst/ adj. 低成本的（不需要花很多钱） 反义词：expensive improves /ɪmˈpruːvz/ v. 改进（变得更好） 近义词：gets better version /ˈvɜːrʒn/ n. 版本（事物的不同形式） scientist/ˈsaɪəntɪst/ n. 科学家（研究科学的⼈） 相关词：science（科学） experiments /ɪkˈsperɪmənts/ n. 实验（测试想法的⽅法） 动词：experiment expensive /ɪkˈspensɪv/ adj. 昂贵的（需要很多钱） 反义词：cheap solve math problems 解决数学问题 write code 编写代码 costs much less 花费少得多 computer chips 计算机芯⽚ free to use 免费使⽤ started projects 启动项⽬ instead of ⽽不是 catch up fast 快速追赶 阅读理解试题 1.
