Seeing someone badly burnt, we should send him for urgent medical help as quickly as we can. Keeping safety in mind can protect us from serious injuries. 提升层写作范文 Knowing proper first‑aid skills matters a lot when accidents happen on campus. Having suffered from chemical burns, the victim needs urgent treatment immediately. Being exposed to acid, the skin will get seriously swollen. Washing the affected area with plenty of cool water is a key step. Never try removing clothing sticking to burnt skin. Giving wrong aid such as applying oil will increase infection risk. His being severely injured reminds every student to value safety and master basic first‑aid knowledge. 07. 课堂总结 动名词（抽象行为）：主语 / 宾语 / 表语 现在分词（主动、进行）：定语 / 宾补 / 状语 主动形式：doing; having done; 被动形式：being done;having been done 否定形式：not doing 复合结构：one’s + doing victim, urgent, acid, organ, choke, scream, collapse urgent attention internal organs stick to 急救词汇 --ing形式 08. 自我评价 Learning Objectives Score(1-5) 1.掌握常见的急救词汇。 2.掌握--ing的句法功能在语境中的应用。 3.运用单元词汇和简单-ing句式描述简单急救场景。 5-完全能；4-基本能；3-不确定；2不太能；1-完全不能 09. 作业布置 生活中，进食过快、异物卡顿极易引发choking（窒息）意外，属于高频危险急救场景。请结合本节课所学急救主题词汇和动词-ing语法结构，完成分层写作作业，所有内容贴合科学急救常识。 基础层任务：基础层（全体必做） 1. 核心要求：使用本节课至少3个急救核心词汇（urgent、victim、choke、collapse、swollen任选）；文中必须包含2种基础-ing结构（doing作主语/定语/伴随状语）；内容贴合窒息急救正确做法，规避错误操作，语句通顺、逻辑清晰。 2. 写作任务：用英文简单介绍异物窒息的基础急救注意事项，面向普通青少年科普。 基础层参考范文： Choking is a common and dangerous accident in daily life. Seeing a person choking suddenly, we must take urgent and scientific first-aid measures immediately. Helping the victim sit straight is the most basic operation. Patting his back properly can help get rid of the stuck foreign matter. Waiting blindly will make the victim collapse due to lack of oxygen. Mastering simple choking first-aid skills can save lives in critical moments. 提升层任务： 1. 核心要求：使用本节课至少5个急救核心词汇；必须包含高阶-ing结构（having done完成式 / being done被动式二选一），同时搭配2种以上基础-ing句法功能；完整阐述窒息急救流程，区分正误操作，句式丰富、语体规范，贴合科普说明文风格。 2. 写作任务：完整科普异物窒息急救流程，说明错误操作的危害，传递科学急救理念。 提升层参考范文： Having encountered a person suffering from severe choking, we should never take wrong first-aid measures. Being pressed blindly on the chest may damage the victim’s internal organs and worsen the dangerous situation. When the airway is blocked, the victim may feel extreme urgent discomfort and even collapse in a short time. Giving standardized back pats and abdominal thrusts is the most effective way to solve choking problems. Mastering professional first-aid knowledge helps us deal with sudden accidents calmly and protect ourselves and others from injuries. Thanks for your attention! $
