仁爱科普版九年级上册 Unit3 Preparing for the Topic
Function & Pronunciation 教学设计
1、 基本信息
教材版本:仁爱科普版九年级上册
课时:1课时(45分钟)
课题:Function(Life-changing inventions)+ Pronunciation(Pause and sense group & Stress, pause and rhythm)
课型:听说语音综合课
2、 教材分析
本节课是Unit3话题前的准备板块,分为Function和Pronunciation两部分。Function板块以改变生活的发明为主题,设置看图讨论、听力匹配、听力填空、小组探究活动,围绕电灯、电话、汽车三项伟大发明,学习一般过去时的被动语态,了解发明、发明者、发明年份;Pronunciation板块重点学习意群停顿、单词重音、朗读节奏,训练学生流利朗读长句和小诗,为整个单元的发明主题学习铺垫语言知识、听力技能和朗读基础,同时渗透科学探索、创新精神的情感教育。
3、 学情分析
九年级学生已经接触过一般过去时,初步了解被动语态结构;对电灯、电话、汽车等发明比较熟悉,对发明故事有兴趣。但是学生容易混淆一般过去时被动语态句式,长句朗读不会合理停顿、重音把握不准,听力抓取关键信息(人名、年份、发明名称)的能力有待训练。
4、 教学目标
知识目标
(1) 掌握词汇:invention, inventor, light bulb, telephone, car, invent, convenient
(2) 掌握核心句型: It was invented in… / It was invented by… These inventions have changed the world.
(3) 理解意群(sense group),学会长句停顿、识别单词重音,把握朗读节奏。
技能目标
(1) 听:能听懂对话,匹配发明、发明者、年份,抓取关键信息完成思维导图;
(2) 说:能简单谈论发明,运用被动语态介绍一项发明;
(3) 读:能够按照意群停顿、重音正确朗读句子和小诗,朗读流畅有节奏感。
情感目标
了解伟大发明对人类的影响,感受发明家的探索精神,激发创新意识,乐于分享自己感兴趣的发明。
5、 教学重难点
✅ 教学重点
一般过去时被动语态句型:sth. was invented by sb. / in +年份
听懂听力材料,获取发明、发明者、发明时间信息,完成思维导图;
识别意群,掌握长句停顿、单词重音,有节奏朗读。
⚠️ 教学难点
区分inventor(发明者)和invention(发明物);熟练运用一般过去时被动语态口头表达;
长句子合理划分意群停顿,朗读时自然把握重音与节奏,不逐词朗读。
6、 教学准备
PPT、听力音频、任务单(思维导图、随堂练习单)、发明图片(汽车、风扇、自行车、耳机、电灯、老式电话)、板书贴纸
7、 教学过程(45分钟)
Step 1. Warming-up & Lead-in 热身导入(5 min)
教师出示Activity1四张图片:car, fan, bike, headphones,提问: Look at these things. They are inventions. Which one helps you most in your daily life? Why?
学生结对简单口头回答,示例:I think the bike helps me most. It helps me go to school easily.
引出主题:Today we will learn some life-changing inventions, like the light bulb, the telephone and the car. We will also learn how to read sentences beautifully. 板书标题:Life-changing inventions
设计意图:从学生熟悉的物品切入,激活已有词汇,自然引出invention主题,营造轻松的听说氛围。
Step 2. Presentation & Function Activity 1-2 新知呈现+听力匹配(12 min)
呈现三个新发明图片:light bulb, telephone, the first car,教授单词: invent v. 发明;inventor n.发明者;invention n.发明物 简单对比:Edison is an inventor. The light bulb is his invention.
呈现表格任务(Activity2),讲解任务要求:listen and match inventions, inventors and years
Inventions
Inventors
Year
The first car
Alexander Graham Bell
1879
Light bulb
Thomas Edison
1886
Telephone
Karl Benz
1876
第一次播放音频,学生完成连线匹配;核对答案。
提炼核心被动句型,板书: Sth. was invented by sb. in +年份. 举例:The light bulb was invented by Thomas Edison in 1879. 引导学生仿照例句口头复述另外两项发明。
设计意图:先扫清词汇障碍,再进行听力输入,抓取基础事实信息;同时呈现本节课核心语法句型,降低理解难度。
Step3. Listening again & Complete the mind map 精听,完成思维导图(10 min)
出示课本思维导图,展示填空任务: Light bulb:It brings us light at night. Telephone:It helps people talk over a distance. Car:It helps people travel conveniently. These inventions have truly changed our world.
第二次播放听力,学生边听边填写;
播放第三遍音频,学生自查,同桌互相核对答案;
核对完成后,教师带领学生根据思维导图复述三个发明的作用,巩固句型。 T: What does the light bulb bring us? S: It brings us light at night. T: What about the telephone? S: It helps people talk over a distance.
设计意图:精听聚焦发明的作用,不再只是时间和人物,深化对主题的理解;思维导图搭建复述支架,为口语输出做好铺垫。
Step4. Pronunciation 语音板块学习(10 min)
讲解概念:sense group(意群):意思相关的一组词,朗读时在这里短暂停顿,不要一个词一顿。
Activity1 句子朗读训练 出示三组句子,斜线/为停顿标记: ① The light bulb was invented / by Thomas Edison. The light bulb was invented / by Thomas Edison / in 1879. As we know, / the light bulb was invented / by Thomas Edison / in 1879. 教师带读,示范停顿;学生齐读、个别抽查朗读,纠正逐词读的坏习惯。
Activity2 小诗Amazing Inventors 讲解重音标记 ',重读的单词要加重语气;斜线停顿。 教师范读→学生跟读→小组竞赛朗读,比拼节奏和重音。 重点提醒:名词、实义动词通常重读,虚词弱读。
小总结:朗读三要素:pause停顿、stress重音、rhythm节奏。
设计意图:由短句到长句,再到韵律小诗,循序渐进训练语音,落实语音板块目标,把语音和本节课发明主题句子结合,不割裂。
Step5. Group work & Output 小组活动(5 min)
完成Activity4 Group work:Find out more inventions you like, introduce them to your group. 给出口语支架: I like ____. It was invented by ____ in ____. It helps us ____. 示例:I like the computer. It helps us get information easily. 小组内轮流介绍,邀请2-3组代表全班展示。
Step6. Summary & Homework 小结+作业(3 min)
课堂小结:师生一起回顾
✅ 句型:Sth. was invented by…in…
✅ 三个发明的信息
✅ 朗读:意群停顿、重音、节奏
分层作业:
基础作业:跟读录音,背诵思维导图内容;朗读Pronunciation部分小诗3遍。
提升作业:查找一项你喜欢的发明,写3句话介绍它(用本节课句型)。
8、 板书设计
Unit3 Life-changing inventions
Function
invent v. 发明 inventor n.发明者 invention n.发明物 ✅ Sth. was invented by sb. in + year.
Light bulb → Edison, 1879 → bring us light at night

Car → Karl Benz, 1886 → help people travel conveniently These inventions have changed our world.
Pronunciation
sense group 意群 / pause 停顿 stress 重音 rhythm 节奏
9、 随堂练习(课堂收尾使用,任务单打印给学生)
1、 匹配连线
Light bulb Alexander Graham Bell 1876 Telephone Thomas Edison 1879 Car Karl Benz 1886
2、 用括号内词适当形式填空
The telephone ____ (invent) in 1876.
Thomas Edison is a great ____ (invent). He had many ____ (invent).
The car helps people ____ (travel) conveniently.
✅ 参考答案:
was invented
inventor; inventions
(to) travel
3、 按意群给句子划停顿(划/)
The first telephone was invented by Bell in 1876.
参考:The first telephone / was invented by Bell / in 1876.
