Have you ever argued with a neighbor? How did you solve it?"Global-reading1.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. He didn't want tomake money from it. He decided to post his design online... for free! People can download the design and make an artificial armwith their own 3-D printers!8What a helping hand!How did Easton come up with the idea? What are Easton’s inventions?
