What does Peter think is the most useful invention of all time ②素材:Fu Xing: What do you think is the most useful invention of all time, Peter Peter: It has to be the radio. Fu Xing: The radio Why Peter: Before the radio was invented, information travelled very slowly. The world was made much smaller by the radio. Suddenly, news could be spread around the world in seconds. Fu Xing: Right. Who was the inventor Peter: An Italian inventor called Guglielmo Marconi. He developed the idea in the 1890s. In 1901, a radio message was sent across the Atlantic Ocean for the first time. ③教师活动:播放或范读对话,提醒学生边读边找出 Peter 认为最有用的发明及理由。 ④学生活动:学生自读对话,圈画发明名称、人物和关键时间,同桌互对。 学习理解获取与梳理 听/读信息抓取准确率设计意图 通过略读抓住对话大意,训练边读边圈画关键信息的习惯。Step 4Work on 3b:Table Work ①任务:Read again and complete the chart. ②素材:Invention: ______;Who was the inventor ______;When was it invented ______;How did it change the world ______。参考答案:Invention: The radio;Inventor: Guglielmo Marconi;When: He developed the idea in the 1890s, and in 1901 the first radio message was sent across the Atlantic Ocean;How changed: ① It made the world much smaller. ② It helped develop other important inventions like the television. ③ It made it easier for people to enjoy music from artists all over the world. ③教师活动:示范如何从原文中找对应信息填入表格。 ④学生活动:学生细读并独立填写,小组核对,用自己的话复述。 学习理解概括与整合 信息梳理完整度设计意图 用表格梳理细节,把零散信息结构化,为复述做准备。Step 5Work on 3c:Role Play ①任务:Listen to the conversation and pay attention to how the key information is stressed. Then role-play the conversation. ②素材:Work in groups。 ③教师活动:示范对话,明确角色分工,提示关键信息处的重音与语调。 ④学生活动:两人一组分角色朗读并表演,注意语音语调和表情。 应用实践描述与阐释 角色扮演表现设计意图 在模仿交际中内化对话语言,提高口语表达的流利度。Step 6Work on 3d:Writing · Presentation ①任务:Choose another invention you think is the most important and make a mind map about it.
