Ⅵ.新素材新型AI模型DeepSeek-R1 (2025·湖南长沙南雅中学调研)阅读理解
中国科技公司DeepSeek研发的新型AI模型DeepSeek-R1目前受到了全球程序员的欢迎。
On January 20, 2025, a Chinese tech company named DeepSeek made a new AI called DeepSeek-R1. This smart programme can solve maths 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 (芯片) 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 practise maths. Other AIs need lots of prepared examples, but R1 improves by itself. For example, in a global maths test, it got 79.8% right, a little higher than OpenAI's model. A simple version (版本) of R1 can even run on low-cost (低成本的) 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 US tech company) top scientist said, "This kind of free AI could change the world."
US 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 (打败) 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.
1. How much did the team spend in building DeepSeek-R1?
A. 5.58 million.
B. 65 billion.
C. 10 million.
2. What can the simple version of R1 do?
A. It can only solve maths problems.
B. It can work on low-cost computers.
C. It can be bad for small companies.
3. Why is DeepSeek-R1 called a "big step forward"?
A. It uses the most expensive tools.
B. It shows smart ideas can beat expensive tools.
C. It was created by US scientists.
4. 中考新考法推断写作意图 What is the main purpose of the article?
A. To compare Chinese and American AI technologies.
B. To explain how computer chips work.
C. To introduce a low-cost AI model from China.
答案: 1. A [解析]细节理解题。根据第一段中的$“The team spent only 5.58 million (\frac{1}{70} of OpenAI's cost) and used 2,048 computer chips($芯片)for two months.”可知,团队研发 DeepSeek-R1 花费 558 万美元。故选 A。 2. B [解析]细节理解题。根据第二段中的“A simple version(版本)of R1 can even run on low-cost(低成本的)computers,helping schools and small companies.”可知,一个简单版本的 R1 甚至可以在低成本的电脑上运行,帮助学校和小公司。故选 B。 3. B [解析]细节理解题。根据第四段中的“A report in Nature magazine called R1‘a big step forward’,proving that smart ideas beat(打败)expensive tools.”可知,《自然》杂志的一篇报道称 R1 是“向前迈出的一大步”,这证明了聪明的想法胜过昂贵的工具。故选 B。 4. C [解析]主旨大意题。全文围绕中国研发的低成本 AI 模型 DeepSeek-R1 展开,介绍其性能、成本优势和开源特性,因此选项 C“介绍一款来自中国的低成本人工智能模型。”正确。故选 C。
