河南省南阳市第一中学2017-2018学年高二上学期英语第二次月考试卷
It all started in 2013, when Shea Stollenwerk, then eight years old, asked for a new hand for Christmas. Shea was born with a partial right hand, which restricts her ability to do things that other kids take for granted.
“My mom went online”, says Shea, who lives in Muknowango, Wisconsin. Shea's mother, Ranee, soon learned about a community of artists, designers, and scientists who are making big breakthrough with artificial hands.
Frankie Flood, a professor at the University of Wisconsin in Milwaukee, was among the designers who saw Ranee's online request. Flood obtained help from fellow professor Adeam Blair and their students, who were learning how to make designs using a 3-D printer. “We made a mold(模子) of Shea's hand out of plaster(石膏), and then we 3-D scanned her hand,” Flood says.
While being fitted in Flood's laboratory, Shea got to choose the color of her new hand. She went with bright pink. She now has a pink hand, a purple hand, and a purple and pink one, and can do things that she couldn't do before, like peeling potatoes, picking up objects, and catching a ball.
Flood and his team have since built hands for six other local children. Indirectly, they have helped dozens more by posting their designs online so that people around the world can print them out. Flood is also working on artificial legs for military soldiers who were injured on the battlefield. “Without a covering, the artificial leg is kind of ugly and plain,” Flood says. “Soldiers want something that will restore the shape of their legs and make them look cooler when they're playing sports.”
As for Shea, the aspiring musician can now play her violin with the help from an adaptive device that Flood's team created. “Nothing is ever going to hold her back,” Shea's father, Steve, told a local reporter.
