Free talk
三问启动:What do you think is the most useful invention in our life? Why do you think so? Do you know who invented it?
示范作答(light bulb—brings us light—was invented by Thomas Edison),提炼「观点+理由+发明者」三要素支架。
说出最有用的发明并说理由;
用 was invented by 报出发明者。
参考答案:示例:I think the light bulb is the most useful invention, because it makes our night bright. And I know it was invented by Thomas Edison.
口语操练
哪件发明帮你最多
组织 Pair work:Look at the pictures and talk about which one helps you most.
示范两组问答:bike——It helps me go to school every day. It is cheap and doesn't cause pollution.;car——It helps people travel to far places easily. It saves lots of time for us.
要求说理由时给出两个支撑点。
结对完成问答;
用 It helps.../It is.../It saves... 说出两点理由。
参考答案:示例:I think the bike helps me most. It helps me go to school every day. It is cheap and doesn't cause pollution.
听力一
发明者与年份匹配
播放对话(科学博物馆场景),布置匹配:三位发明者(Bell/Edison/Benz)×三个年份(1876/1879/1886)×三项发明。
核对并追问关键句:the first telephone was invented by Alexander Graham Bell in 1876。
听对话完成匹配;
复述发明者—发明—年份三联。
参考答案:Thomas Edison—light bulb—1879;Alexander Graham Bell—telephone—1876;Karl Benz—car—1886
听力二
完成思维导图
再放录音,布置 Complete the mind map:每项发明带来的改变三空。
讲评关键信息:Edison brought us light at night(一生发明两千多件);Bell——people could already talk over a distance;Benz——more convenient to travel by car than on horseback。
点拨「发明+影响」双信息抓取:年份发明者是明线,影响短语是暗线。
边听边填思维导图三空;
按导图完整复述三项发明。
参考答案:1. light at night 2. talk over a distance 3. travel more conveniently
语法精讲
was
were done (+by)
讲解句型:主语+was/were+过去分词(+by+执行者)——某物(被某人)发明。
强调 by 短语取舍:需要说出是谁做的才加 by,可省略——The telephone was invented in 1876.(省 by)vs The light bulb was invented by Thomas Edison.(带 by)。
补充 the first+名词:第一个……——The first car was invented by Karl Benz.
记 by 短语取舍规则;
把三句时间型被动补上发明者改写。
参考答案:The telephone was invented by Alexander Graham Bell in 1876. 等改写;the first car/telephone/light bulb+was invented
口语输出
Group work 发明介绍
布置 Group work:查资料向组员介绍感兴趣的发明。
以相机范文提炼黄金四句框架:was invented by... in.../is made of.../is used for.../I think it is...
点拨:过去被动讲来历、现在被动讲现状,两种被动在一篇介绍里各司其职。
按四句框架口头介绍一件发明;
组内互评四要素是否齐全。
参考答案:示例:I'd like to introduce the camera. It was invented by Joseph Nicéphore Niépce in 1826. It is made of glass and plastic. It is used for taking photos. I think it is a wonderful invention.
语音精讲
停顿 Pause
讲解短停顿(意群之间,轻微换气)——The light bulb was invented / by Thomas Edison / in 1879.;长停顿(完整句末,完成换气)——It was invented by Karl Benz in 1886. //
标点规则:逗号处一般用短停顿 /,句号问号感叹号结尾用长停顿 //——As we know, / the great invention changed our world. //
记停顿两条规则;
给例句标注 / 与 // 并试读。
参考答案:意群之间短停顿 /;句末长停顿 //;逗号→/,句号问号感叹号→//
语音操练
意群停顿递增朗读
组织两组递增朗读:①The light bulb was invented / by Thomas Edison.→+in 1879→+As we know,;②There are a few steps / to follow.→+in the invention process→+The scientist tells us 前置。
引导发现规律:句子加长→意群增多→短停顿增加,句末长停顿不变。
指导练法:先铅笔划意群边界再读,边界轻换气、句末深换气。
完成两组递增朗读;
总结意群与停顿的对应关系。
参考答案:第 1 组:The light bulb was invented / by Thomas Edison / in 1879.(As we know, / 前置);第 2 组:The scientist tells us / there are a few steps / to follow / in the invention process.
朗读实践
Amazing Inventors
布置朗读小诗:We're in'ventors... Our in'ventions are 'here to 'stay!(注意重读、停顿与节奏)。
重音提示:in'ventors/in'ventions/ma'chines 重音在第二音节;感叹句句末长停顿高降调。
组织小组展示,按「重读突出/停顿到位/节奏自然」三条互评。
按意群划停顿、标重音;
齐读并分组展示互评。
参考答案:短停顿落在意群之间;感叹句 anywhere!/away!/stay! 句末长停顿;重读 inventors/inventions/machines/great/land/air/high/far

思维品质:被动时态辨析与信息整合
一般现在/过去被动判断;宾语从句语序;四要素整合成篇
2. 预设反思点:
本课命门有二。Function 侧:听力思维导图三空填的是「发明带来的改变」而非发明者——学生易把 light at night 填成 Thomas Edison,讲评时强调导图分层(人物层已定,本层填影响);语法点 was/were done 的 by 取舍要结合听力原句双向示范(时间型省 by/人物型带 by)。介绍四句框架是本课口语落点,过去被动讲来历、现在被动讲现状的分工要在范文里指给学生看(was invented by... in 1826 vs is made of... is used for...)。Pronunciation 侧:停顿规则看似简单,标点线索(逗号→短停顿、句末标点→长停顿)是学生最容易漏记的抓手;递增朗读三句设计巧妙——句子加长时意群随之增多而句末长停顿不变,让学生自己发现这条规律比直接告知更有效。小诗 Amazing Inventors 的重音难点在 in'ventors/in'ventions 二音节重读,与常见 -tion 后重读规律一致,可顺带归纳。检测第 2 题宾语从句「陈述语序+时态呼应 He was」是双重考点,第 1、3 题构成「陈述被动 vs 疑问被动」对照,讲评时并列呈现。
