一、文章原文

PASSAGE · 同色高亮 = 定位词

P1On January 20th, 2025, a Chinese tech company named DeepSeek created a new AI called DeepSeek-R1. This smart program can solve maths problems, write code, and answer questions as well as top models such as Open AI's GPT-40, but it costs much less to build. The team spent only $5.58 million (1/70 of Open AI's cost), used 2,048 computer chips and completed the project in just two months. This shows that good ideas can beat big spending.

P2DeepSeek-R1 learns by trying many times and improving, just like students practise maths. Other AIs need many prepared examples, but R1 gets better by itself. Besides, a simple version of R1 can even run on low-cost computers, helping schools and small companies.

P3DeepSeek-R1 is free to use and modify. 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 a top scientist at Meta, a famous US tech company, said, "This kind of free AI could change the world."

P4US 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.

P5As a DeepSeek engineer said, "We want AI to be a friend, not something only the rich can use." With R1, China shows that great things come from creativity and hard work, not just money.

二、题目精析

QUESTIONS · 定位原文 + 选项翻译

What can DeepSeek-R1 do according to Paragraph 1?

根据第一段，DeepSeek-R1 能做什么？

细节定位

A. ①②③写代码、解数学题、做实验
做实验不是它的功能。
B. ①③④写代码、做实验、回答问题
做实验不是它的功能。
C. ②③④解数学题、做实验、回答问题
做实验不是它的功能。
D. ①②④写代码、解数学题、回答问题 ✓
P1: "solve maths problems, write code, and answer questions"——没有做实验。

How much does it cost to build Open AI?

建造 Open AI 花费多少？

数字计算

A. About $5.58 million.约558万美元。
这是 DeepSeek 的成本。
B. About $65 billion.约650亿美元。
这是 Meta 计划花的钱。
C. About $390 million.约3.9亿美元。✓
$5.58M 是 Open AI 的 1/70，5.58×70≈390M。
D. About $300.约300美元。
这是做实验的费用。

What does the underlined word "it" in Paragraph 3 refer to?

第三段中划线的 "it" 指的是什么？

指代判断

A. GPT-40.GPT-40。
上下文不相关。
B. Open AI.Open AI。
Open AI 在第一段出现，第三段没有提到它。
C. Meta.Meta。
Meta 在 it 之后才出现，不可能指代后面的词。
D. DeepSeek-R1.DeepSeek-R1。✓
第三段开头说"DeepSeek-R1 is free to use"，后文"started projects to study it"的 it 指代本段主语 DeepSeek-R1。

What does the engineer mean by saying the underlined sentence in the last paragraph?

最后一段划线句子，工程师想表达什么？

句意理解

A. To explain why R1 is free.解释为什么 R1 是免费的。✓
"not something only the rich can use" 呼应前文 free to use。
B. To compare R1 with Meta's AI.比较 R1 和 Meta 的 AI。
不是比较。
C. To encourage students to study maths.鼓励学生学数学。
过度推断。
D. To show that expensive AI models are useless.证明昂贵的 AI 模型没用。
太绝对——文章没说昂贵模型没用。

What is the main purpose of the passage?

这篇文章的主要目的是什么？

主旨大意

A. To explain how computer chips work.解释电脑芯片如何工作。
只提了一句 chips。
B. To introduce a low-cost AI model from China.介绍来自中国的低成本 AI 模型。✓
全文围绕 DeepSeek-R1 的低成本、高性能展开。
C. To encourage students to become programmers.鼓励学生成为程序员。
不是文章目的。
D. To compare Chinese and American AI models.比较中美 AI 模型。
比较是手段，不是目的。
