Unit 7 A Day To Remember Section A 2a-2e 课时教学设计
一、教材分析
(一)单元主题
本单元以 “A Day to Remember” 为主题,聚焦 “描述过去的特殊经历”,通过真实情境培养学生运用一般过去时叙述事件的能力。
(二)课时定位
Section A 2a-2e 为听说实践课,通过 Fu Xing 参观污水处理厂的对话,引导学生理解污水处理流程,并能模仿描述自己的旅行经历,渗透环保教育。
(三)语言重点
1. 词汇:wastewater plant, remove, germ, step, easy/hard 等形容词对比。
2. 句型:“First…Then…Next…After that…” 描述流程;“I used to think it was easy…” 表达认知转变。
3. 语法:一般过去时的巩固应用。
二、学情分析
(一)优势
学生已掌握一般过去时的基本结构(如 went, saw, did 等),对 “学校旅行” 话题有生活经验,易于产生共鸣。
(二)挑战
1. 乡镇中学学生听力输入量较少,对 “污水处理厂” 等专业场景词汇较为陌生。
2. 口语表达中可能存在时态混用、流程描述逻辑不清的问题。
3. 缺乏真实语境练习,综合输出能力较弱。
(三)学情适配
通过图片、流程图等可视化工具降低理解难度,设计分层任务(如从词汇填空到完整叙述)逐步提升输出信心。
三、课时目标
维度 具体目标
语言能力
1. 能听懂关于污水处理厂参观的对话,抓取关键信息(如流程步骤、感受)。
2. 能用 “First…Then…” 等序列词描述污水处理流程。
3. 能口头介绍一次特殊的旅行经历,正确使用一般过去时。
文化意识
理解水资源净化的复杂性,树立 “节约用水” 的环保意识。
思维品质
通过对比 “easy/hard” 等反义词,分析污水处理的难度,培养逻辑思维。
学习能力
通过小组合作完成流程复述,提升同伴互助学习能力。
Learning Objectives
1.Understand the conversation about Fu Xing’s wastewater plant trip;
2.Use a flow chart to introduce how a wastewater plant turns dirty water to clean water;
3.Introduce one of your holiday trips to a special place.
四、评价任务及教学重难点
(一)课堂检测
1. 听力填空(2a):检测对关键词(clean, dirty, large, small 等)的抓取能力。
2. 流程图排序(2b-2c):评估流程描述的逻辑连贯性。
3. 小组对话展示(2e):观察一般过去时的正确使用及情感表达(如语调、表情)。
(二)形成性评价
1. 自评表(迁移创新环节):学生从 “语言准确性”“发音”“表现力” 三方面打分。
2. 师评:通过课堂观察记录学生参与度(如是否主动提问、纠正时态错误)。
教学重难点:通过 Fu Xing 参观污水处理厂的对话,引导学生理解污水处理流程,并能模仿描述自己的旅行经历,渗透环保教育。
五、学习活动设计
(一)情景导入(5 分钟)
1. 过去时态热身
展示课件图片(如 “went swimming” “visited a museum”),学生快速抢答动词过去式,复习核心词汇。
2. Free Talk
提问:“Do you remember your last school trip? Where did you go? What did you do?” 引导学生用简单句分享经历,激活话题背景。
(二)学习理解(15 分钟)
1. 预测与听力(2a)
Fu Xing went there for a school trip. Can you guess where the place is for?
(1)展示污水处理厂图片,提问:“What do you think happens in a wastewater plant?” 引导学生预测关键词(如 clean water, machines)。
How did Fu Xing feel about?
It was really interesting!
What did she see there?
She saw the plant make dirty water clean again.
(2)听对话填空,重点关注形容词(clean/dirty, large/small, easy/hard),体会污水处理的对比过程。
Fu Xing: We saw the plant make dirty water _______ again.
Helen: Really? How?
Fu Xing: Well, first, _______ water from our homes goes into the plant. Then,
special screens remove large pieces of waste from the water.
Helen: What happens next?
Fu Xing: Well, _______ machines remove germs and other things from the
water. These things are usually too _______ to see. It takes a few more steps
after that before the water becomes clean again.
Helen: Wow! I used to think it was _______ to get clean water.
Fu Xing: Me too! I didn’t realize it was so _______.
ANSWERS : clean dirty large small easy hard
2. 流程梳理(2b-2c)
(1)阅读对话,匹配句子成分(如 “The plant makes dirty water clean again”),强化流程逻辑。
(2)完成短文填空,复述流程:“First, dirty water goes to the plant. Then screens remove large waste….”
Read the conversation and match the sentence parts. 2b
1.The plant makes A. remove small things from the water.
2.Dirty water goes B. it was easy to get clean water.
3.Machines inside the plant C. dirty water clean again.
4.Screens inside the plant D. remove large pieces of waste from the water.
5.Helen used to think E. into the plant
Answers : 1C2E3A4D5B
(三)应用实践(12 分钟)
1. 模仿与朗读(2b)
(1)听录音模仿语调,注意重读关键词(如 “interesting”“hard”)。
(2)小组分角色朗读,教师巡视纠正发音(如 “germs”/dʒɜːmz / 的连读)。
2. 流程图制作
学生用简笔画绘制污水处理步骤(进水→筛除大垃圾→机器除菌→多步处理→出水),并用英语标注关键词,同桌互述流程。
(四)迁移创新(10 分钟)
1. 小组讨论(2e)
(1)提供参考场景(theatre/museum/zoo 等),学生选择一个地点,用以下框架讨论:
• How was your trip?
• What did you see/do there?
• How did you feel? Did you learn anything?
(2)小组派代表汇报,教师板书优秀表达(如 “used to think… but now realize…”)。
2. 情感升华
展示缺水地区图片,提问:“Why should we save water?” 引导学生结合污水处理流程,讨论节水措施(如 “reuse kitchen water”)。
(五)总结与练习(3 分钟)
1. 师生共同梳理重点:一般过去时句型、流程描述词、环保理念。
2. 随堂练习(单项选择,见课件),巩固词汇(waste, used to be, realize 等)。
六、作业设计(分层实施)
1.The cake is so big. I want to cut it into ________.

(二)提升作业
写一段 40 词左右的短文,描述一次难忘的旅行(包含 where, what, how 等要素)。
(三)拓展作业
设计 “节约用水” 海报,用简笔画展示污水处理流程,并添加标语(如 “Every drop counts!”)。
