【话题分析】
学生通过主篇章的 学习认识到伟大的发明可以改变人类生活、推动社会进步，同时也进一步了解了如何介绍发明的一般方法。本节课是写作课，主要输入语篇与输出语篇均为对“发明” 的介绍，重点围绕发明的背景（原因）、发明的外观、独特性、功能、重要意义等方面展开，有利于学生内化说明性语篇的结构化知识，也便于教师开展“整体输入——整体互动——整体输出”的整体教学设计。写作板块要求学生借助“思维导图”构思，并仿照范文的框架结构，充分发挥想象力，设计出富有创意的发明并写一篇短文介绍自己的新发明。
写作步骤
1. 确定主题与框架：
明确要介绍的发明是什么"What it is"，比如文中先点明 "My invention is a flying car." ，清晰给出发明物。
2. 描述外观特征：阐述发明的样子
"What it looks like"，像 "The flying car has four wheels and two wings." ，从组成部件等方面介绍外观。
3. 说明功能作用：
介绍发明能做什么"What it can do"，例如 "It can run on land and fly in the air. It has a top speed of 300 km/h... The car can be controlled by voice." ，讲运行速度、操控方式等功能 。
4. 阐述优势好处：
提及发明带来的益处"Benefits of my invention" ，如 "It is fast, convenient and green... My invention will help people avoid traffic jams. It will make driving a more exciting experience too." ，从环保、缓解交通、提升体验等角度说好处 。
5. 总结收尾：
可简单总结发明的价值，让内容完整，比如文中虽未单独总结句，但整体围绕发明的价值展开描述，也可补充类似 "This flying car will surely bring great changes to people's travel and life." 这样的句子强化收尾。
