Unit 3 Starting out & Understanding ideas课件-2025-2026学年外研版（2024）英语八年级上册

该初中英语课件围绕“发明”主题，涵盖发明相关词汇、不定式和动名词作宾语等核心知识点。通过图片象征意义分析（如灯泡代表创意、梯子象征实现步骤）和古今生活差异对比（住房、衣物等）导入，建立发明与生活变化的联系，形成从概念到实例的学习支架。 其亮点在于结合真实案例（Easton发明机械手臂）和多模态活动（图片分析、听力问答、阅读任务），培养语言能力（用目标词汇讨论发明）、思维品质（分析Easton解决重量问题的过程）和学习能力（合作提取信息）。例如，听力提问发明材料、成本，阅读分析优势，学生在探究中提升语言运用和问题解决能力，教师可借助结构化活动高效组织教学。

(He posted it online to make money. / He posted it online for free. / He posted it online for a 3-D printer.) 16 17 Easton LaChappelle, a 14-year-old student, stood beside his work at a science fair. It was a robotic arm. He built it out of plastic blocks and fishing line. 18 “Hello,” said a girl with an artificial arm, as she shook hands with Easton’s work. 19 This was the first time Easton met Jenny, a girl with a special condition. She was born without an arm. Her artificial arm was just a simple hook, but it cost $80,000. What’s worse, children like her grow quickly and need new arms all the time. 20 “It blew me away! I built my arm for only $300,” thought Easton. “I must lend a hand to people like her.” 21 After the fair, Easton’s room became a lab. He stayed there all day. He always tried to improve his work. For his 16th birthday, Easton got a 3-D printer. 22 And with it, he invented an artificial arm. It was able to move with brain signals of the user. But it wasn’t good enough yet: the arm weighed 3.6 kilograms. It was too heavy for a child. 23 Easton kept working on it. He enjoyed fixing problems one after another. And finally he hit on success at age 23. His design only weighed 0.5 kilograms and cost around $500! 24 Easton’s invention has helped many children. He didn’t want to make money from it. He decided to post his design online… for free! 25 People can download the design and make an artificial arm with their own 3-D printers! What a helping hand! 26 05 Exercise 27 ____Easton made a robotic arm with plastic blocks and fishing line. ____Easton allowed people to use his design for free. ____Easton and Jenny met at a science fair. ____Easton made an artificial arm with a 3-D printer.
