这是一篇介绍中国高铁静音车厢相关规则的语篇语法填空题，解题时首先通读全文，明确文章主题和整体叙事逻辑，再逐空结合语法规则、固定搭配、上下文语境逐一推导：
1. 看到空前的助动词has，立刻对应现在完成时have/has+动词过去分词的结构，变形start的正确形式即可；
2. 空后是具体网站名称，回忆“在某网站上”的固定介词搭配就能得出答案；
3. 空后是座位等级class，要表达“二等座”的含义，需要把基数词two转换为对应的序数词；
4. 本句是if引导的条件状语从句，符合“主将从现”规则，从句用一般现在时，主句要使用一般将来时；
5. 空后是可数名词单数message，此处表示泛指“一条提醒消息”，填入对应不定冠词即可；
6. 空前是连词when，属于状语从句的省略结构，逻辑主语you和listen是主动关系，要用现在分词形式；
7. 此处泛指所有需要看管孩子的家长，要用parent的复数形式，句首首字母大写；
8. 空格修饰前面的实义动词speak，修饰动词需要使用副词，把形容词soft变为副词形式；
9. 空格前后两个分句是顺承并列的逻辑关系，选择对应并列连词即可；
10. 回忆固定搭配would like to do sth. 表示“想要做某事”，直接变形括号内的词即可。
【解析】
1. 现在完成时结构为“have/has + 动词过去分词”，空前已有助动词has，start的过去分词为started，故填started。
2. 表示“在网站上”的固定搭配为on the website，此处填介词on。
3. 表示“二等座”的固定表达为second class，需将基数词two变为序数词second，故填second。
4. if引导的条件状语从句遵循“主将从现”原则，从句为一般现在时，主句用一般将来时will+动词原形，故填will find。
5. message是可数名词单数，此处泛指“一条提醒消息”，message以辅音音素开头，用不定冠词a，故填a。
6. 此处是时间状语从句的省略，完整结构为when you are listening to music，省略主语和be动词后用现在分词listening，故填listening。
7. 此处泛指所有家长，要用可数名词复数形式parents，位于句首首字母大写，故填Parents。
8. 空格修饰动词speak，需要用副词作状语，形容词soft的副词形式为softly，故填softly。
9. 空格前后两个动作“知道乘客下车时间”和“轻声告知乘客”是并列顺承关系，用并列连词and连接，故填and。
10. 固定搭配would like to do sth. 意为“想要做某事”，故填to buy。
【答案】
1. started 2. on 3. second 4. will find 5. a 6. listening 7. Parents 8. softly 9. and 10. to buy
【知识点】
现在完成时，词形转换，固定搭配
【点评】
本题选取贴近现实生活的高铁静音车厢作为语篇主题，考点覆盖中小学阶段核心的语法填空考点，既考察学生对基础时态、冠词、介词、连词的掌握程度，也考察词形变换、非谓语动词的相关用法，难度适中，同时引导学生关注身边的社会发展新事物。

六、阅读理解。(2025·江苏宿迁期中)
Recently, the world has been very excited about a new AI model called DeepSeek - R1. 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.
()1. What does Paragraph 2 mainly say about DeepSeek - R1?
A. It's new.
B. It's free.
C. It's special.
D. It's popular.
()2. Why is being open - source important?
A. Because it changes our needs.
B. Because it helps share knowledge.
C. Because it makes AI cheaper.
D. Because it uses new technology.
()3. What is the passage mainly about?
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.

六、1. D 【点拨】根据第二段中的“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.”可知，DeepSeek - R1 在短时间内迅速流行并成为中国应用商店的头号免费应用。故选 D。
2. B 【点拨】根据最后一段中的“Being open - source is very important for sharing knowledge and making technology（技术）better for everyone”可知，开源有助于知识共享，使技术惠及更多人，扩大 AI 的使用范围。故选 B。
3. C 【点拨】通读全文可知，本文围绕 DeepSeek - R1 的性能、成本、学习方式和开源特点展开，属于对该 AI 模型的整体介绍。故选 C。

【分析】
这是一篇介绍新型AI模型的说明文阅读理解，三道题分别对应段落主旨、细节理解、全文主旨三类常规考点，解题思路如下：
1. 第一题询问第二段的核心表意，先定位到第二段梳理内容：该AI模型2025年1月20日首次亮相，仅一周就击败ChatGPT成为中国区App Store免费应用榜首，这个核心信息直接体现它受众认可度高、传播速度快的特点，逐一比对选项排除次要信息和无关选项即可得出答案。
2. 第二题询问开源属性的重要性原因，直接用题干关键词"open-source important"回文定位到最后一段的引语部分，找到原文对应的表述就能直接匹配正确选项。
3. 第三题考察全文主旨，通读全文可以发现文章从开发主体、发布热度、性能成本优势、训练方式、开源特点多个维度展开，整体是对DeepSeek-R1的完整介绍，排除仅覆盖局部内容的干扰项就能得到答案。
【解析】
1. 第1题：第二段核心信息是DeepSeek-R1发布仅一周就超越ChatGPT登顶中国区App Store免费应用排行榜，直观体现该应用短时间内收获大量用户、十分受欢迎的特点。A选项“它是新的”只是段落开篇的次要信息，B选项“它是免费的”是榜单属性的附带描述，C选项“它很特别”在第二段无对应支撑，均排除，选D。
2. 第2题：根据文章最后一段原文"Being open-source is very important for sharing knowledge and making technology better for everyone"，可知开源的重要性体现在助力知识共享、让技术普惠更多人，直接对应选项B。A选项“改变我们的需求”是用户修改代码的作用，C选项“让AI更便宜”是该模型本身的属性，D选项“使用新技术”无原文支撑，均排除。
3. 第3题：全文依次介绍了DeepSeek-R1的开发主体、发布热度、低算力低成本优势、强化学习的训练逻辑、开源属性，整体是对该新型AI模型的完整介绍，对应选项C。A选项“不同AI模型的差异”仅在第三段有少量提及，不是全文核心；B选项“DeepSeek-R1面临的问题”全文完全没有涉及；D选项“开源的重要性”只是文章最后一段的局部内容，不能概括全文，均排除。
【答案】
1. D 2. B 3. C
【知识点】
英语细节理解，段落主旨归纳，全文主旨把握
【点评】
本题选材贴合当下科技热点，属于难度平缓的常规阅读理解题，考点都是初中英语阅读的核心基础考点，没有设置强迷惑的干扰选项，学生只要掌握题干关键词回文定位的基础解题方法，就能快速匹配原文内容选出正确答案，同时选材也能帮助学生拓展前沿科技相关的课外认知。
