What’s the ‘helping hand’? It could be an artificial arm and helps people with arm problems. It may be about an invention about a helping hand . Who lost arms ? ①Easton 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. ②“Hello,” said a girl with an artificial arm, as she shook hands with Easton's work. ③This 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. ④“It blew me away! I built my arm for only $300,” thought Easton. “I must lend a hand to people like her.” ⑤After 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 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. ⑥Easton 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! ⑦Easton's invention has helped many children. He didn't want to make money from it.

Third, he didn’t care about making money. Some people think Easton should sell his design to make money for more inventions. Do you agree? Why or why not? Careful-reading First, his invention was useful—it solved a big problem for kids like Jenny, who needed a light, cheap arm instead of the expensive, heavy ones. Second, he shared it for free. That means more kids could get the arm, because people could make it themselves with a 3-D printer. Third, he didn’t care about making money. He just wanted to help others. That kind heart makes his "helping hand" truly great. 问题可能有点多 但是我个人认为都是很好的问题 从helping hand 出发“授人以鱼不如授人以渔” 传授给网上人一些相应的制作方法 然后绿色的辩证问题 让学生去思考需不需要make money 两边都是很现实的 一边是可以用更多的钱 去做更多的发明 一方面就是去帮助别人。 13 14 Easton LaChappelle, a 14-year-old student, stood beside his work at a science fair.

He decided to post his design online... For free! People can download the design and make an artificial arm with their own 3-D printers! What a helping hand! How would Jenny’s life change with Easton’s invention? What can you learn from Easton? Jenny would get a lighter, cheaper artificial arm. She can use it more easily and doesn’t need to spend a lot of money. Her life will be more convenient and easier. Kindness：He wanted to help Jenny after seeing her problem. Persistence：He kept improving the arm for years (from 14 to 23). Selflessness：He shared his design for free to help more children, not for money. Further thinking Have you ever stuck with a difficult task for a long time? What kept you going, and what did you learn from it? I spent years improving my invention. Yes, I once spent half a year practicing basketball. My love for the sport and the dream of joining the school team kept me going. I learned that persistence brings progress.
