课程名称 《英语 基础模块2》(语文版2022版) Unit4 Environmental Protection (Grammar & Writing) 课型 Grammar 课时 1 授课班级 授课时间 45mins 授课教师 教材分析(Textbook Analysis) 1. 地位和作用:本课时是Unit4的语言建构核心,聚焦时间、地点、原因、目的四种状语从句的用法,涵盖核心连词、从句结构、时态呼应等关键知识点,是“用英语连贯描述环保行动、解释环保原因、明确环保目的”的语法支架,贴合中职环保、文旅、服务类专业“环保方案撰写、绿色宣传推广、职场沟通表达”的职业需求,落实中职新课标“语言能力+职业应用+核心素养”的要求。 2. 知识衔接:依托前序“环保核心词汇”(protect, recycle, reduce, pollute, energy, waste)、“简单句基本结构”,系统串联四种状语从句的“连词选择+结构搭建+场景应用”,填补“表达动作时序、地点范围、因果关系、行动目的”的表达短板,为后续“职场环保文案撰写、跨文化环保交流”搭建完整语法体系。 3. 适应性分析:教材中“垃圾分类、节能减排、污染治理”等语料为语法学习提供真实场景,补充“职业场景状语从句应用”(如环保宣传:“We should save water when we use taps.”);重点突破“连词辨析”“从句时态呼应”“句子合并”等难点,让语法学习服务于环保话题的实际表达。 学情分析(Study situation analysis) 1. 知识储备:已掌握环保核心词汇和简单句结构,零散接触过when、because等基础连词,但对四种状语从句的完整分类、连词区别(如when/while/as、because/since/as)、从句时态规则完全陌生,不会主动用从句丰富表达。 2. 能力水平:能写简单环保主动句(如“We recycle waste paper.”),但短文存在“句式单一、逻辑不连贯”问题,无法用从句描述“环保行动的时间节点、实施地点、背后原因、最终目的”等复杂场景。 3. 兴趣态度:对“校园环保、绿色生活”话题兴趣浓厚,需通过“环保宣传文案升级”“状语从句闯关”等趣味任务降低语法枯燥感,激发学习主动性。 4. 学习困难:易混淆when/while/as的用法;不清楚because/since/as的语气差异;忽略主句与从句的时态呼应(如主句将来时,时间/条件从句用现在时);不会正确合并简单句为含状语从句的复合句。 学习目标(Learning objectives) 1. 知识目标: 掌握核心连词:时间状语从句(when, before, after, while, as soon as)、地点状语从句(where, wherever)、原因状语从句(because, as, since)、目的状语从句(so that, in order that); 掌握核心规则:从句位置(句首/句中/句尾)、标点使用、时态呼应(如主句将来时,时间从句用现在时); 掌握关键区别:when/while/as的用法差异、because/since/as的语气强弱、状语从句与定语从句的区分; 掌握核心句型:四种状语从句的基本结构及环保场景例句。 2. 技能目标: 能准确判断环保场景中状语从句的类型及连词用法; 能完成教材中状语从句相关练习(划线、选择类型、合并句子、翻译)及补充练习; 能撰写60词环保主题短文,包含至少4种不同类型的状语从句。 3. 情感目标: 通过用状语从句连贯描述环保行动,增强用英语解决复杂表达问题的自信; 感受语法对表达逻辑性、连贯性的提升作用,培养绿色环保意识和社会责任感。 学习重难点(Learning key &difficult points) 重点: 1. 四种状语从句的核心连词及环保场景例句; 2. 教材中状语从句练习的准确完成; 3. 简单句合并为含状语从句的复合句的基本方法; 4. 环保短文撰写中状语从句的多样化运用。 难点: 1. 连词辨析(when/while/as、because/since/as); 2. 从句时态呼应规则(如as soon as引导的时间从句“主将从现”); 3. 写作中根据语境灵活选择状语从句类型,增强表达的逻辑性和连贯性。 教学方法(Teaching methods) 1. 任务驱动法:设计“状语从句环保闯关”“环保宣传文案升级”“环保短文优化”等任务,以任务推动学习; 2. 情景教学法:全程依托“校园垃圾分类、社区节能减排、环保活动策划”等真实环保场景; 3. 游戏互动法:“连词配对接龙”“从句类型找茬”“句子合并大挑战”等游戏强化记忆; 4. 示范对比法:通过“简单句vs复合句”“不同连词表达效果”的对比,凸显状语从句的表达价值。 课前准备(Preparation before class) 教师准备: 1. PPT(含状语从句分类图表、环保场景图片、连词辨析表格、教材练习答案); 2. “状语从句连词卡片”(正面连词、背面用法+环保例句); 3. 教材练习单、短文写作模板、连词辨析对照表; 4. “环保宣传小能手”奖励贴纸。 学生准备: 1. 复习Unit4核心环保词汇(protect, recycle, reduce, pollute, energy, waste, tap, bin等); 2. 复习简单句基本结构(主谓宾、主系表); 3. 预习基础连词(when, where, because, so that)的常见用法。 教学媒体(Teaching media) 多媒体课件(PPT)、状语从句连词卡片、教材练习单、写作模板、连词辨析对照表、奖励贴纸 教学过程(Teaching process) 教学环节(Teaching Steps) 教师活动设计(Teacher Activity designs) 学生活动设计(Student Activity Designs) 设计意图(Design Intentions) Step1 导入(Lead-in) 1. 情景展示:拿出学生课前写的环保简单句(如“We save water. We use taps.”),笑着说:“大家的环保意识真强!但这两句话连在一起有点生硬,怎么让它更流畅?比如‘我们用水龙头时要节约用水’,这就需要今天的‘语法神器’——状语从句!” 2. 句子对比:展示两个版本: ① We save water. We use taps. ② We should save water when we use taps.(含时间状语从句) 提问:“哪个版本更连贯?状语从句是不是让环保表达更专业?”(预设学生:第二个!能说清什么时候节约用水,逻辑更清晰!) 3. 引出主题:“今天咱们就解锁‘四大状语从句’,掌握时间、地点、原因、目的从句的用法,让环保表达从‘简单句堆砌’升级为‘逻辑满分小作文’!” 1. 看到自己写的句子被展示,兴奋又好奇,主动思考句子优化方法; 2. 对比两个版本,踊跃回答:“第二个更连贯!‘when’能连接两个动作,说清环保行动的时间,比单独两句更自然!” 3. 对“四大状语从句”充满期待,主动拿出笔记本准备记录核心知识点。 用学生自己的句子导入,拉近距离;通过“简单句vs复合句”的直观对比,凸显状语从句的实用价值,激发学习动机,契合环保表达的真实需求。 Step2 Grammar 一、四大状语从句“环保讲堂”(结合环保场景逐一讲解) 用“句子搭积木”比喻:“简单句是单独的积木,连词是连接扣,状语从句就是把两块积木精准拼在一起,让句子更有逻辑!” 1. 时间状语从句: 核心连词:when(当……时)、before(在……之前)、after(在……之后)、while(在……期间)、as soon as(一……就……) 环保例句: • Turn off the lights when you leave the classroom.(离开教室时关灯。) • We should sort waste before we throw it away.(扔垃圾前要分类。) 提问:“‘我们一到社区就开始捡垃圾’,用as soon as怎么说?”(预设学生:We will start picking up litter as soon as we arrive at the community.) 关键规则:主句用将来时,从句用一般现在时(如:As soon as we finish the plan, we will carry it out.) 2. 地点状语从句: 核心连词:where(在……地方)、wherever(无论哪里) 环保例句: • Put the recyclable waste where the green bin is.(把可回收垃圾放在绿色垃圾桶所在的地方。) • We should plant trees wherever there is empty land.(无论哪里有空地,我们都应该种树。) 提问:“‘在有污染的地方,我们要及时清理’,用where怎么说?”(预设学生:We should clean up in time where there is pollution.) 3. 原因状语从句: 核心连词:because(因为,表直接原因)、as(由于,表明显原因)、since(既然,表已知原因) 环保例句: • We should save energy because it is limited.(我们要节约能源,因为它是有限的。) • As the river is polluted, we can't swim in it.(由于河水被污染了,我们不能在里面游泳。) 提问:“‘既然大家都知道环保的重要性,就行动起来吧’,用since怎么说?”(预设学生:Since everyone knows the importance of environmental protection, let's take action.) 4. 目的状语从句: 核心连词:so that(以便)、in order that(为了) 环保例句: • We plant more trees so that we can improve air quality.(我们多种树,以便改善空气质量。) • We reduce plastic use in order that we can protect the ocean.(我们减少塑料使用,为了保护海洋。) 提问:“‘我们要节约用纸,以便保护森林’,用so that怎么说?”(预设学生:We should save paper so that we can protect forests.) 二、连词辨析“避坑指南” 1. when/while/as:when可接瞬间/延续动作,while接延续动作,as表“一边……一边”; 例句:When he turned off the tap, I was cleaning.(他关水龙头时,我在打扫。)/ While we are recycling, we learn a lot.(我们回收时,学到很多。) 2. because/since/as:because语气最强,回答why;since/as语气较弱,表已知/明显原因。 1. 跟随教师学习四大状语从句,记录每种从句的连词、结构和环保例句,在笔记本上绘制“从句分类表”; 2. 积极回应教师提问,尝试用不同连词完成环保句子,主动纠正错误(如时态误用); 3. 学习“避坑指南”,标记易混淆连词,小组讨论:“‘我们一边植树一边讨论环保知识’用as怎么说?”(As we are planting trees, we are discussing environmental knowledge.) 4. 用连词卡片配对:拿到“where+可回收垃圾”卡片,配对“Put recyclable waste where the green bin is.” 用“句子搭积木”比喻让复杂语法具象化;每种从句都配环保场景例句,降低理解难度;“避坑指南”针对性解决连词辨析难点;互动提问和卡片游戏强化记忆,突破时态呼应和句子结构等重点。 Step3 Writing 1. 写作任务:“环保行动短文3.0版”,要求60词左右,包含: 至少4种不同类型的状语从句; 覆盖“环保行动的时间、地点、原因、目的”等场景; 2. 模板: 开头(点题):I take part in environmental protection activities every week. 中间(时间+地点):______ (时间从句),I go to the community ______ (地点从句) to do volunteer work. 中间(原因+目的):We do this ______ (原因从句),and we try our best ______ (目的从句). 结尾(总结):I believe the environment will be better if we keep working hard. 3. 示例:“I take part in environmental protection activities every week. When I have free time, I go to the community where there are many litter spots to do volunteer work. We do this because the environment is important to everyone, and we try our best so that we can make our city cleaner. I believe the environment will be better if we keep working hard.” 4. 巡视指导,提醒:“when引导的时间从句,主句将来时从句用现在时;because表直接原因,不能和so连用哦!” 1. 参考模板,结合自己的环保经历撰写短文,如:“I take part in environmental protection activities every week. After I finish my homework, I go to the park where there are many trees to water them. We do this as the weather is dry, and we try our best in order that the trees can grow well. I believe the environment will be better if we keep working hard.” 2. 检查自己的短文:是否有4种不同状语从句?连词使用是否正确?时态是否呼应? 3. 主动向教师确认:“‘As the weather is dry’用as引导原因从句对吗?” 模板降低写作难度,任务要求融入四种状语从句,让学生感知语法对表达逻辑性的提升作用;结合自身环保经历让写作有内容,落实“用语法解决实际表达问题”的技能目标。 Step4课堂练习(Class Exercise) 一、教材练习 1. 教材练习1(Read and pay attention to the adverbial clauses): 划出下列句子中的状语从句,标注类型(时间/地点/原因/目的): ① We should turn off the lights when we leave the classroom.(时间状语从句) ② I always take a bath before I go to bed.(时间状语从句) ③ You can go where you want to go.(地点状语从句) ④ He thinks he can get a good score because he is studying very hard.(原因状语从句) ⑤ He works hard so that he can get a skill certificate.(目的状语从句) 2. 教材练习2(Underline the adverbial clauses and choose their types): 划出状语从句并选择类型(a.时间 b.地点 c.原因 d.目的): ① When you do not use a house device, turn it off.(a) ② Where there is a will, there is a way.(b) ③ We encourage each student to do a small thing on campus so that they can protect the environment as an individual.(d) ④ The doctor advised her to live where the air is fresher.(b) ⑤ Since he said it was his fault, we will take no further action against him.(c) 3. 教材练习3(Combine sentences with the adverbial clauses): 用括号内的连词合并句子: ① The doctor advised me to live in that place.
