This was the first time Easton met Jenny.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. “It blew me away！I built my arm for only $300,”thought Easton.“I must lend a hand to people like her. 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 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. 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! 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!People can download the design and make an artificial arm with their own3-D printers！ What a helping hand！ 64 ·上 21.knock over 22.have a hard time doing 23.on purpose 24.do research 25.continue to do 26.take risks 援助之手 在科技展上，l4岁的学生Easton LaChappelle 站在他的作品旁边。那是一个机械臂。他是用塑 料积木和钓鱼线制作的。 “你好。”一个戴着假肢的女孩一边说，一边和 Easton的作品握手。 这是Easton第一次见到珍妮。她天生缺少一 只手臂。她的假肢只是一个简单的钩子，却花费 了8万美元。更糟糕的是，像她这样的孩子长得 快，经常需要新的假肢。 “这让我大吃一惊！我只花了300美元就造 出了假肢，”Easton心想。“我必须帮助像她这样 的人。” 在展会结束后，Easton的房间变成了一个实 验室。他整天都待在那里。他不断努力改进自己 的作品。在他16岁生日时，Easton得到了一台3D 打印机。利用这台打印机，他发明了一只假臂。 它能够通过使用者的脑电波来操控。不过，这只 手臂还不够完美：这条手臂重达有3.6公斤。这对 一个孩子来说太重了。 Easton继续埋头研究。他喜欢一个接一个地 解决问题。经过不断改进，最终，他在23岁时获 得了成功。新版假肢手臂只有0.5公斤重，制作 成本也降到了500美元左右！ Easton的发明帮到了很多孩子。但他压根没 想靠它赚钱。他决定把设计图纸免费公开！现在 只要上网下载他的设计图，大家用家里的3D打印 机就能自己制作假肢手臂了！ 多大的帮助啊！ Reading for writing ② The power of curiosity Albert Einstein once said,"I have no special talents.I am only passionately curious."The greatest inventions in history would be impossible without curiosity. Curiosity can bring new discoveries.Benjamin Franklin is a great example.He was drawn to electricity and had a deep curiosity about its nature.He did lots of research to try to understand it.For example,he flew a kite during a storm.His curiosity led him to invent the lightning rod.This invention protects buildings from lightning. Curiosity can also make people brave.Just look at Wan Hu,the Ming Dynasty pioneer of space exploration.He was so curious about space that he invented a "flying chair"!He lost his life while testing this invention.Despite the failure,his curiosity gave future explorers ideas.People learnt from his example,and created safer ways to explore space. But curiosity is more than just taking risks.It also drives people towards certain goals.Zhang Heng,a Chinese scientist and inventor,was curious about the world:how did everything in the world move?He spent years studying the sky and the earth.Finally,he drew China's first star map, and invented the first earthquake detector.His curiosity continues to influence scientists today. As Jacques Cousteau said,"What is a scientist after all?It is a curious man looking through a keyhole,the keyhole of nature,trying to know what's going on."Curiosity is the key.It opens one door after another for us to discover a new world.

Second,I think you can join some clubs in your school.In this way,you can share your hobbies with your friends so that you can get along well with each other. Third,as for after-school activities,I think being a volunteer is a good activity.Not only can it help others,but it can also teach you to do things on your own. I hope my advice is helpful to you. Yours, Dr Smith
