Unit 5 Section B (3a-3c ）Writing & Project 课件 2026-2027学年人教版九年级英语上册

该初中英语课件围绕“发明的力量”主题，聚焦被动语态和现在完成时的运用，通过“Look and say”图片填空（如无人机被展示、海报被悬挂）激活语法知识，以飞机发明文本为载体，用图表梳理发明者、时间等信息搭建阅读支架，衔接信息提取、研究笔记到写作输出的学习脉络。 其亮点在于融合语言能力与思维品质，如Project环节让学生分组选择绿色科技等领域设计发明海报，需说明材料、用途等，既运用被动语态又培养问题解决能力。通过反思环节（如“如何用被动语态谈论发明”）提升学习能力，学生能增强语言运用与合作创新能力，教师可借助结构化活动设计和评价标准优化教学。

Unit 5 Power of Ideas Secion B (3a-3c )Writing & Project By the end of this lesson, we will be able to： 1. obtain specific information about the invention of the plane (inventor, time, challenges, impact), and complete the chart. 2. express opinions on impressive inventions and explain how inventions change lives. 3. use what we learn to make a poster about invention ideas through group work. Learning Objectives Look and say. Use the passive voice to fill in the blanks. Several drones(无人机)    to students.（show） are shown Look and say. Use the passive voice to fill in the blanks. Posters about scientific inventions up on the wall.（hang） are hung Look and say. Use the passive voice to fill in the blanks. Three water bottles on the table.（place） are placed Look and say. Use the passive voice to fill in the blanks. The school’s science exhibition（展览） in this hall.（hold） is held 通过导入激活旧知 Look and say. Use the passive voice to fill in the blanks. The table with a white tablecloth.（decorate） is decorated Which was the first plane in the world? Look at the pictures. The invention of the plane has greatly changed the world. However, it seems that its inventors, Orville Wright and Wilbur Wright, were not looking to change the world at all. Rather, they just wanted to fly like birds. To solve the problem of heavier-than-air flight, the Wright brothers began working with gliders. There were two main challenges. The first was how to get the glider into the air. The second was how to control it once it was flying. For both problems, they found their solutions by looking at how birds flew. After they solved these problems, they added an engine to the glider. Then, in December 1903, the world’s first plane flights were made. The invention of the plane has made our travels around the world much easier and faster. Journeys that once took days, weeks, or even months, can now be made in only a few hours. As a result, communication among people in different countries is now much easier, and the world has become a much smaller place. 现在完成时 似乎 相反 挑战 一旦 解决方法 通过观察 被动语态 much修饰比较级 曾经 结果是 The invention of the plane has greatly changed the world.
