[2019·合肥市高三调研性检测]The San Francisco Giants added a special pitcher (投球手) for the day. It was small — yet fierce — Hailey Dawson, who has a 3Dprinted hand.
The energetic 8yearold from Nevada was invited to throw out the first pitch at the Giants game on Sunday. Hailey was born with Poland syndrome, a disorder in which affected individuals were born with missing or underdeveloped muscles o one side of the body. It affected her hand.
With a traditional prosthetic (义肢的) hand potentially costing thousands of dollars, Hailey's mom, Yong Dawson turned to the University of Nevada, Las Vegas for help. She emailed UNLV College of Engineering, and they accepted the challenge. Brendan O'Toole, chairman of the mechanical engineering department, said he and his team had got a lot of requests, “but this one was different.” They got to work using a 3Dprinter. Several prototypes (原型) and fittings later, Hailey got her first hand about four years ago.
Hailey's mother said the hand had given her daughter a wonderful lift. “When she puts this robotic hand on, it changes her personality and confidence level，” Yong Dawson told CBS San Francisco. “I love seeing that. I just wanted her to have an even playing field.”
When she arrived at AT&T Park on Sunday, Hailey got to hang out with players in the shelter at the side of the sports field. They even let her try on their Series rings.
Using her 3Dprinted hand, Hailey threw out the perfect first pitch. Then with a wave and a smile, she headed into the stands to cheer on her newfound friends on the Giants.
体裁：说明文 题材：新闻报道 主题：3D打印假肢
【语篇解读】 本文主要介绍了内华达大学工程学院的工作人员用3D打印技术帮助一个患有Poland综合征的小女孩打印假肢的事情。
【难句分析】 Hailey was born with Poland syndrome, a disorder in which affected individuals were born with missing or underdeveloped muscles on one side of the body.
分析：本句是一个复合句。in which相当于where，引导定语从句，在从句中作地点状语，修饰先行词disorder；disorder是Poland syndrome的同位语。
译文：Hailey出生时患有Poland综合征，患这种病的人天生身体一侧肌肉缺失或者发育不全。
1．What caused the function loss of Hailey's hand?
A．A serious brain disorder.
B．A born physical problem.
C．An awful game accident.
D．An unexpected infection.
答案与解析：B 考查细节理解。根据第二段第二句“Hailey was born with Poland syndrome, a disorder in which affected individuals were born with missing or underdeveloped muscles on one side of the body”可知，Hailey手功能丧失是天生的生理上的问题，故选B。
2．Why did Yong Dawson ask the University of Nevada for help?
A．She couldn't find a suitable hospital.
B．She knew it had the advanced 3Dprinter.
C．She couldn't afford a traditional prosthetic hand.
D．She was forced to accept the tough challenge.
答案与解析：C 考查细节理解。根据第三段第一句“With a traditional prosthetic (义肢的) hand potentially costing thousands of dollars, Hailey's mom, Yong Dawson turned to the University of Nevada, Las Vegas for help”可知，Yong Dawson向内华达大学求助的原因是传统的假肢费用昂贵，她支付不起，故选C。
3．What is Hailey's mother's attitude towards the 3Dprinted hand?
A．Skeptical. B．Positive.
C．Ambiguous. D．Cautious.
答案与解析：B 考查观点态度。根据第四段第一句“Hailey's mother said the hand had given her daughter a wonderful lift”和第四段的内容可推知，Hailey的妈妈对3D打印手持积极的态度，觉得这能够让孩子受到鼓舞，故选B。
4．Which of the following is the best title for the text?
A．Mother's love makes a huge difference
B．A talented young pitcher gets a great future
C．The 3Dprinting technology is changing our life
D．A girl with a 3Dprinted hand throws her first pitch
答案与解析：D 考查标题判断。文章前两段点题，并结合全文的内容可推知，本文主要讲述了一个身患Poland综合征的小女孩安装了3D打印手，从而实现了在运动场上投球的可能性的故事，故选D。
干扰项分析：A项错在母爱的伟大只是文章中所体现的其中一个方面，而非主题思想；B项错在文章中并没有提及天才投球手前途无量；C项错在3D打印技术正在改变我们的生活，概括的面过于宽泛，与文章中的事例有所偏离。
