【分析】
做这类补全对话题，首先要先通读完整对话，明确对话核心是两人围绕上学的出行方式展开交流，之后逐空结合上下文的问答逻辑匹配选项：
1. 第一空后面对方的回答是“我骑自行车上学”，显然空处是对出行方式的提问，对应匹配选项；
2. 第二空前半句提到“我的父母不让我骑自行车”，空处需要补充说明父母不让骑车的原因，找对应表原因的选项即可；
3. 第三空前文对方提问“你怎么到校？”，需要回应自己的出行方式，匹配对应答语；
4. 第四空前文是一般疑问句“地铁上拥挤吗？”，后文又补充说人多不太舒服，说明此处是肯定回答，匹配一般疑问句的肯定应答选项；
5. 第五空后文回应“是个好主意但对我来说太贵了”，说明空处是对方提出的某一种出行建议，匹配对应提建议的选项即可。
【解析】

五、阅读理解。(2025·江苏宿迁期中)
Recently, people around the world have been very excited about AI models. DeepSeek-R1 is one of them. The company behind it, also called DeepSeek, is a business in Hangzhou, Zhejiang.
The new AI model first appeared on 20 Jan. 2025. In just one week, it beat OpenAI's ChatGPT and became No. 1 free application(应用程序) in the App Store in China.
According to DeepSeek, the new AI model is as good at dealing with difficult activities as other AI models. But it needs much less computing power(算力) to do that. It is also one of the cheapest of its kind.
How does DeepSeek-R1 learn? Instead of using the traditional ways, DeepSeek mainly uses reinforcement learning(RL, 强化学习). It helps the AI model learn by working out the right way to do things on its own to get points. This makes DeepSeek-R1 better at reasoning and solving hard problems.
What's more, DeepSeek-R1 is open-source(开放源代码的). Everyone is free to get a copy of its code(代码). They can also change the code to meet their own needs. "Being open-source is very important for sharing knowledge and making technology(技术) better for everyone," said Liang Wenfeng, who set up DeepSeek.
(
A. It's new.
B. It's free.
C. It's special.
D. It's popular.

A. Because it changes our needs.
B. Because it helps share knowledge.
C. Because it makes AI cheaper.
D. Because it uses new technology.

A. The differences between AI models.
B. The problems faced by DeepSeek-R1.
C. The introduction to DeepSeek-R1.
D. The importance of being open-source.

【分析】
做这篇阅读理解可以按照“题干关键词定位→匹配原文信息→排除干扰选项”的思路逐步解题：
1. 第一题询问第二段的核心主旨，先定位到第二段内容，该段给出DeepSeek-R1上线仅一周就登顶中国区App Store免费应用榜首的事实，可直接推导出它的受众认可度高、十分受欢迎，再排除只覆盖局部细节的片面选项即可得到答案。
2. 第二题询问开源的重要性，直接定位到最后一段的人物引语部分，将原文表述和选项逐一匹配就能选出正确答案。
3. 第三题是全文主旨题，先梳理全文脉络：文章开篇引出DeepSeek-R1这款AI模型，后续依次介绍它的上线热度、低算力优势、强化学习的训练方式、开源属性，整体都是围绕这款AI产品展开介绍，排除只能覆盖局部内容的干扰项就能确定主旨。
【解析】
1. 第1题：第二段仅用数据说明DeepSeek-R1上线一周就超过ChatGPT成为中国区App Store免费应用第一名，直接体现该应用受众认可度高、十分受欢迎。A选项“它是新的”、B选项“它是免费的”都只是第二段的零散细节，无法概括整段核心，C选项“它很特别”在第二段没有任何相关支撑，因此选D。
2. 第2题：根据最后一段DeepSeek创始人的表述“Being open-source is very important for sharing knowledge and making technology better for everyone”，可知开源的核心价值之一就是助力知识共享。A选项“改变我们的需求”是用户修改代码的目的，不是开源重要的原因；C选项“让AI更便宜”是前文提到的DeepSeek-R1本身的性能特点，和开源属性无关；D选项“使用新技术”原文无对应表述，因此选B。
3. 第3题：全文从研发主体、上线热度、性能优势、训练逻辑、开源特点多个维度，完整介绍了DeepSeek-R1这款AI模型。A选项“不同AI模型的差异”原文没有展开多模型对比；B选项“DeepSeek-R1面临的问题”全文完全没有提及；D选项“开源的重要性”只是最后一段的局部内容，无法覆盖全文，因此选C。
【答案】
1. D 2. B 3. C
【知识点】
阅读理解细节定位，阅读理解主旨归纳
【点评】
这是一篇结合当下科技热点的说明类阅读，考点设置清晰，以基础细节题和主旨题为主，没有设置偏难的干扰项，学生只要能准确定位题干对应的原文内容，排除以偏概全的错误选项就可以顺利得分，很适合锻炼快速抓取文本关键信息的能力。
