2026年全国一卷高考英语听力独白四维精细化学案（2） 整体设计说明 本学案依托高考听力真题原文，打造朗读精读、语法刷题、书面写作、口语输出四位一体的闭环训练模式。全程采用课堂实用训练结构，习题与任务前置，答案、解析、范文统一后置，适配学生限时独立练习、课后纠错复盘，贴合高考能力考查方向。 Task 1 真题原文朗读&精读背诵（建议用时：5min） 朗读要求：规范断句、流畅连读，熟记核心句型，积累听力场景词汇与写作通用素材，实现听、读、写素材互通。 Before we begin today's experiment, let's review the lab rules. First, safety glasses must be worn at all times, even if you're only watching. Second, never mix chemicals unless the instructions tell you to do so. Today we're using a strong acid which can cause serious burns if it touches your skin. If any chemical container is knocked over, don't panic. Tell me immediately and I'll handle the cleanup. Also, keep your hair tied back and avoid wearing loose clothes. We will work in pairs. One person will handle the tools while the other records the data. Switch roles after every three trials to ensure everyone gets practice. Remember: the goal is accurate data, not speed. If you finish early, do not start a new experiment. Instead, clean your workspace thoroughly. Any questions? No? All right. Let's have a safe and productive class. 精读核心拓展（高考必考） 1. 高频核心词汇（听读写通用） experiment n. 实验｜review v. 回顾；温习｜instruction n. 操作说明；指令｜chemical n. 化学药品 adj. 化学的｜acid n. 酸｜burn n. 灼伤｜container n. 容器｜panic v. 慌张；惊慌｜handle v. 处理；操作｜thoroughly adv. 彻底地｜productive adj. 高效的；富有成效的 2. 高频短语积累 at all times 始终；随时｜mix chemicals 混合化学试剂｜knock over 打翻｜tie back 束起（头发）｜loose clothes 宽松衣物｜work in pairs 双人合作｜switch roles 互换角色｜accurate data 精准数据｜workspace 工作区域 3. 长难句精讲（适配语法填空、读后续写） 原句：Today we're using a strong acid which can cause serious burns if it touches your skin. 句式：定语从句 + 条件状语从句（嵌套复合句） 句意：今天我们要使用一种强酸，该物质一旦接触皮肤会造成严重灼伤。 4. 文体主旨与高频考点 文体：正式口语独白（高考听力高频体裁，课堂指令、实验讲解、规则宣讲场景） 场景：高中实验室课前规则讲解 主旨：教师课前宣读实验室安全准则、分组操作要求、实验核心目标及课后收尾规范，保障实验安全高效开展。 听力高频出题点：安全穿戴要求、化学试剂使用禁忌、突发情况处理方式、分组分工规则、实验核心原则、课后操作规范 Task 2 语法填空（真题改编·限时训练）（建议用时：10min） 训练要求：独立限时完成，不查阅资料，完成后对照文末答案解析纠错整理。 阅读下面短文，在空白处填入1个适当的单词或括号内单词的正确形式。 Before we begin today's experiment, let's review the lab rules.

Firstly, you must wear safety glasses all the time and avoid loose clothes. Secondly, never mix chemicals without instructions. When accidents like spilled chemicals happen, keep calm and turn to teachers for help immediately. Besides, work in pairs and switch roles properly. Prioritize accurate data over speed and clean your workspace after the experiment. Let’s observe rules to make our experiments safe and productive. 写作提分与避坑指南 1. 高频加分短语：ensure safety 保障安全｜prioritize...over... 重……轻……｜turn to sb. for help 求助某人｜observe rules 遵守规则 2. 常见扣分点：情态动词误用、被动语态缺失、句式单一、要点遗漏 3. 通用句型：To ensure..., we should...

Once a chemical container is knocked over, do not panic and ask teachers for help at once.We usually work in pairs and switch roles to gain enough practice. We should always remember that accurate data matters more than speed. After finishing the experiment, we need to clean our workspace thoroughly. Only by following strict rules can we finish experiments safely and efficiently. 训练优化要点 1. 语音语调：规则类陈述语句调平稳，情态动词、核心动词适当重读 2. 素材复用：本文素材可通用校园规则、安全须知、自律规范类写作与口语话题 3. 核心加分词汇：safety priority 安全优先｜efficiently adv. 高效地｜blindly adv. 盲目地｜observe regulations 遵守规章 学科网（北京）股份有限公司 $
