Quicker and faster 3-D printers have allowed not just amazingobjects to be created, but have started to affect how doctors treat patients.
We’ve put together a list of some of the most amazingmedical breakthroughs made possible with 3-D printing.
Life-Saving Airway
In 2013, doctors created a new airway for kaiba Gionfriddo, aboy born with an airway that kept collapsing (萎陷). To save hislife doctors printed tiny tubes to join together in different shapes and sizesuntil one finally worked for Kaiba. It was placed in Kaiba’sbronchus (支气管) so that itno longer collapsed. Even more remarkably, once the plant was placed it couldstay there. It’s designed to eventually be absorbed into the body.
New “Bionic” Hands
One of the most remarkable ways 3-D printing is now being usedis as a way to create prosthetics (假肢). A boy bornwithout an arm named Alex was able to get a new“bionic”hand thanks to it. Lastyear a college student spent 8 weeks coming up with a special prosthetic designthat only cost a few hundred dollars in materials. He said he wanted to createa prosthetic far cheaper than other choices that can run tens of thousands ofdollars.
A practice Heart
In Seattle, doctors have been able to use 3-D printingtechnology to“practice”risky operations so that they will face fewer surprisesin the operating room. Kami Sutton was born with her heart“in the wrong place”.For a recent operation her doctor was able to take many scans of Sutton’s heart and print out a model. “Kami’s heart is trulyone-of-a-kind,”Dr. Stephan Seslar, a heart disease specialist said. “Operatingon her without understanding the structure of her heart better could be very dangerous.”
A New Skull
A U.K. man was able to have part of his skull rebuilt thanks toa 3-D printer. Stephen Power broke his cheek bones in a crash. To help Powerhis doctors instead created 3-D bones all carefully printed in the shape of hisface. “This is really the first time we’ve taken it to this stage,where everything has been planned and modeled in advance — and workedsweetly,”said Adrian Sugar, a doctor.
（1）What is special about the 3-D printed airway?

C.Its materials.
D.Its shape design.
（3）How can 3-D printing technology help doctors in the operating room?
A.It helps them get better scans.
B.It guarantees the success of operations.
C.It enables them to practice and learn more.
D.It helps them to deal with patents, anxiety.
（4）What does Adrian Sugar think of the new skull printed by 3-D technology?
A.He has doubts about it.
B.He thinks highly of it.
C.It needs to be better planned.
D.It functions well but needs improving.

Answer 1

【答案】
（1）C
（2）A
（3）C
（4）B
【解析】本文属于科普说明文，主要介绍了3D打印技术在医疗行业上取得的良好效果，并列举了四个具体的案例。
(1)C 细节理解题。根据第四段最后两句Evenmore remarkably, once the plant was placed it could stay there. It’sdesigned to eventually be absorbed into the body.可知当3D打印技术制造出来的气管，一杯放进病人的身体里，它就能被病人的身体接受。这才是最不同寻常的地方。所以C项内容正确。
(2)A 细节理解题。根据第六段第三句Lastyear a college student spent 8 weeks coming up with a special prosthetic designthat only cost a few hundred dollars in materials.可知使用3D打印技术生产出来的仿生手花费的钱很少。所以这种仿生手的优势是价格低廉。故A正确。
(3)C 推理判断题。根据第八段最后两句.For a recent operation her doctor was able to take many scans of Sutton’s heart and print out a model. “Kami’s heart is trulyone-of-a-kind,”Dr. Stephan Seslar, a heart disease specialist said. “Operatingon her without understanding the structure of her heart better could be verydangerous.”可知在做手术之前，医生就扫描了Sutton的心脏并使用3D打印技术把模型打印出来进行模拟的手术练习。让医生对手术过程中可能出现的问题有了事先了解，所以3D打印技术可以帮助医生练习并有更多了解。故C正确。
(4)B 态度意图题。根据文章最后一句“Thisis really the first time we’ve taken it to this stage, whereeverything has been planned and modeled in advance — and worked sweetly,”saidAdrian Sugar, a doctor.可知这是他们第一次把这一技术运用到这一阶段，手术之前一切都进行了模拟练习，最终结果非常好。由此内容可知AdrianSugar对3D打印技术是很支持的。故B正确。
