Great inventions Lead-in: Look at the pictures and answer the questions. What are these inventions? How have they changed our lives? Do you know other inventions? What do you think is the greatest invention? Have you ever argued with a neighbor? How did you solve it?" It may be about a boy and his invention (the artificial arm) . Look at the word cloud, the title and the picture, then predict. What’s the passage about? Have you ever argued with a neighbor? How did you solve it?" Global-reading 1.Order the following events in the passage. _______Easton made a robot arm with 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. 2.How many parts can the article be divided into? 1 Easton LaChappelle, a 14-year-old student, stood beside his workat a science fair. It was a robotic arm. He built it out of plasticblocks and fishing line. 2 “Hello," said a girl with an artificial arm, as she shook hands withEaston's work. 3 This was the first time Easton met Jenny, a girl with a specialcondition, She was born without an arm, Her artificial arm wasjust a simple hook, but it cost $80,000. What's worse, children likeher grow quickly and need new arms all the time. 4 “It blew me away! I built my arm for only $300," thought Easton.“Imust lend a hand to people like her. 5 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. And with it, he invented an artificial arm. It wasable 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 achild. 6 Easton kept working on it. He enjoyed fixing problems one afteranother, And finally he hit on success at age 23. His design onlyweighed 0.5 kilograms and cost around $500! 7 Easton's invention has helped many children.

Why was Easton so shocked? Further thinking Easton’s robotic arm Jenny’s artificial arm Built out of：_________________________________ Cost: ______________________ Cost: What’s worse: ————————————————————————————————— plastic blocks and finishing line $300 just a simple hook $80000 Children like her grow quickly and need new arms all the time. He always tried to _______his work. Careful-reading Part2 P5-6 He invented an _______ arm. It was able to move with ________ of the user.

He hit on ________ at age 23. improve artificial brain signals good 3.6 working success What did he do next? 变式朗读 He always tried to improve his work.  It was able to move with brain signals of the user.  But it wasn’t good enough yet: the arm weighed 3.6 kilograms. He enjoyed fixing problems one after another. And finally he hit on success at age 23. Further thinking Was Eastern pleased with his first artificial arm? Why or why not? Yes, because it was able to move with brain signals of the user. No, because it was too heavy for a child. Careful-reading Part3 P7-8 1.What did Easton do with his successful artificial arm? He decided to post his design online ...for free! 2.Why did he do so? Because he just wanted to help people in need. He didn’t want to make money from it. He decided to post his design online... for free!  What a helping hand! 变式朗读 Careful-reading What did Easton do with his invention? science fair without an arm grow quickly fishing line move weighed cost design Retell Easton’s story What did Easton do with his invention?
