Unit 3 Great Ideas Function & Pronunciation 课时基本信息 课 题 Unit 3 Great Ideas — Function & Pronunciation 课 型 听说与语音课(45分钟) 年 级 九年级上册 版 本 仁爱科普版(2024)英语九年级上册 教学重难点 【教学重点】 掌握一般过去时被动句型(主语+was/were+过去分词+by+执行者),谈论发明的发明者、时间及用途,掌握朗读的意群、停顿(短停顿/长停顿)、重音和节奏 【教学难点】 辨析一般现在时与一般过去时被动语态,正确运用于语句中,整合多项信息,自主完成发明主题的口头介绍与汇报 词汇速览 inventor / n vent / n. 发明者;发明家(invent v. 发明 inventor 发明者 invention n. 发明) convenient /k n vi ni nt/ adj. 方便的,便利的(It is convenient to do sth 做某事很方便) distance / d st ns/ n. 距离;远处(talk over a distance 远距离交谈;in the distance 在远处) pause /p z/ n./v. 停顿;暂停(short pause 短停顿/long pause 长停顿) (一)热身 Free talk Free talk 三问:What do you think is the most useful invention in our life?(生活中最有用的发明是什么?)Why do you think so?(为什么?)Do you know who invented it?(知道谁发明的吗?) 示例:I think the light bulb is the most useful invention in our life, because it brings us light and makes our night bright. And I know it was invented by Thomas Edison. 【提示框】 表达支架:I think is the most useful, because And I know it was invented by——观点+理由+发明者三要素。 (二)口语操练 哪件发明帮你最多 【过渡语】改变生活的发明就在身边,选一件说说理由。 Pair work. Look at the pictures and talk about which one helps you most.(看图谈哪件发明帮你最多) 示例一(bike):A: Which of these inventions helps you most? B: I think the bike helps me most. A: Why? B: It helps me go to school every day. It is cheap and doesn't cause pollution. 示例二(car):B: I think the car helps me most It helps people travel to far places easily. It saves lots of time for us. (三)听力一 发明者与年份匹配 Listen to the conversation and match the pictures with the information.(听对话把图片与信息匹配) 三位发明者:Alexander Graham Bell(贝尔)/Thomas Edison(爱迪生)/Karl Benz(本茨);三个年份:1879/1886/1876。 Thomas Edison—light bulb—1879;Alexander Graham Bell—telephone—1876;Karl Benz—car—1886 匹配三题:发明者—年份—发明配对 发明者与年份匹配 (四)听力二 完成思维导图 【过渡语】再听一遍,把每项发明「带来什么」装进思维导图。 Listen again and complete the mind map.(Kangkang 与 Li Xiang 在科学博物馆谈展品) 对话要点:①灯泡——It is said that it was invented in 1879. The inventor was Thomas Edison. He brought us light at night with his invention. He invented more than two thousand things in his whole life.(爱迪生一生发明两千多件)②电话——the first telephone was invented by Alexander Graham Bell in 1876. Over a hundred years ago, people could already talk over a distance.③汽车——It was invented by Karl Benz in 1886. It is surely more convenient to travel by car than on horseback. These great inventions have truly changed the world. 思维导图三空(词库 light at night/people talk/people travel more conveniently/over a distance):Edison——brought us ;Bell——people ;Benz——. 【知识点】 听力抓「发明+影响」双信息——年份与发明者配对是明线,每项发明带来的改变(light at night/talk over a distance/travel more conveniently)是暗线;思维导图填的是影响短语。 1. light at night 2. talk over a distance 3. travel more conveniently 思维导图三空:Edison/Bell/Benz 各自带来的改变 发明思维导图 (五)语法精讲 was/were done (+by) 句型:主语+was/were+过去分词(+by+执行者):某物(被某人)发明——注意只有需要说出是谁做的,才加 by 短语,可以省略。 例:The telephone was invented in 1876. 电话于 1876 年被发明。(只讲了时间,省略 by)/The light bulb was invented by Thomas Edison. 灯泡是由托马斯 爱迪生发明的。 the first+名词:第一个……——The first car was invented by Karl Benz. 第一辆汽车是卡尔 本茨发明的。 【知识点】 by 短语取舍——要报发明者就加 by+人,只讲时间地点就省略;the first+名词+过去被动是介绍「第一件发明」的固定搭配。 (六)口语输出 Group work 发明介绍 【过渡语】四要素集齐,正式介绍一件你感兴趣的发明。 Group work. Find more information about the inventions that you're interested in, and then introduce them to your group members.(查资料向组员介绍感兴趣的发明) 范文(相机):I'd like to introduce the camera. It was invented by Joseph Nic phore Ni pce in 1826. It is made of glass and plastic. It is used for taking photos and keeping beautiful moments. We can record our happy days with it. I think it is a wonderful invention. 四要素框架:发明者+时间(was invented by in)/材料(is made of)/用途(is used for)/评价(I think it is)。 【提示框】 介绍 invention 的黄金四句:was invented by in/is made of/is used for/I think it is——过去被动讲来历,现在被动讲现状。 (七)语音规则 停顿 Pause ①Short pause 短停顿:意群和意群之间——同一句内不同意群间做很短的停顿、轻微换气,不代表语义结束——The light bulb was invented / by Thomas Edison / in 1879. ②Long pause 长停顿:陈述句、疑问句等完整句子的末尾——语义完全结束,停顿比短停顿久,完成换气——It was invented by Karl Benz in 1886. // 注意:逗号处一般用短停顿 /;句号、问号、感叹号结尾使用长停顿 //——As we know, / the great invention changed our world. // 【知识点】 停顿两条规则——意群之间短停顿 /(轻微换气),整句结束长停顿 //(完成换气);标点线索:逗号 短停顿,句号/问号/感叹号 长停顿。 短停顿与长停顿规则 (八)语音操练 意群停顿递增朗读 Read the sentences. Pay attention to the sense groups and the pauses in each group of sentences.(读句注意意群与停顿) 第 1 组三句递增: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. 第 2 组三句递增:There are a few steps / to follow. There are a few steps / to follow / in the invention process. The scientist tells us / there are a few steps / to follow / in the invention process. 规律:句子加长,意群增多,短停顿 / 随之增加,句末长停顿 // 不变。 【提示框】 练法:先铅笔划出意群边界(/),再读——意群内部连贯不停,边界处轻换气,句末深换气。 (九)朗读实践 Amazing Inventors 【过渡语】一篇小诗综合演练——重读、停顿、节奏一起上。 Read the text. Pay attention to stresses, pauses and rhythms.(朗读小诗注意重读、停顿与节奏) We're in'ventors. / We have made 'great in'ventions / since our 'birth. / Our in'ventions can go 'slow / or 'really 'fast. / And there are some in'ventions / from the 'past. Our ma'chines go over 'land / and through the 'air. / Our in'ventions can 'take us 'anywhere! Our in'ventions / 'fly us 'high / and 'far away! / And our in'ventions / are 'here to 'stay! 重音提示:in'ventors/in'ventions/ma'chines 重音在第二音节;感叹句句末用长停顿与高降调。 短停顿 / 落在意群之间(We have made 'great in'ventions / since our 'birth.);感叹句 anywhere! / away! / stay! 句末长停顿 //;重读落实义词 inventors/inventions/machines/great/land/air/high/far 朗读任务:按意群划停顿、标重音后齐读小诗 Amazing Inventors 朗读文本 (十)随堂检测 单项选择 独立完成单项选择,再同桌核对并说出判断依据。 1.
