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 (支氣管) 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.

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.

（3）C
（4）B
【解析】本文屬于科普說明文，主要介紹了3D打印技術(shù)在醫(yī)療行業(yè)上取得的良好效果，并列舉了四個具體的案例。
(1)C 細(xì)節(jié)理解題。根據(jù)第四段最后兩句Evenmore remarkably, once the plant was placed it could stay there. It’sdesigned to eventually be absorbed into the body.可知當(dāng)3D打印技術(shù)制造出來的氣管，一杯放進(jìn)病人的身體里，它就能被病人的身體接受。這才是最不同尋常的地方。所以C項內(nèi)容正確。
(2)A 細(xì)節(jié)理解題。根據(jù)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打印技術(shù)生產(chǎn)出來的仿生手花費的錢很少。所以這種仿生手的優(yōu)勢是價格低廉。故A正確。
(3)C 推理判斷題。根據(jù)第八段最后兩句.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.”可知在做手術(shù)之前，醫(yī)生就掃描了Sutton的心臟并使用3D打印技術(shù)把模型打印出來進(jìn)行模擬的手術(shù)練習(xí)。讓醫(yī)生對手術(shù)過程中可能出現(xiàn)的問題有了事先了解，所以3D打印技術(shù)可以幫助醫(yī)生練習(xí)并有更多了解。故C正確。
(4)B 態(tài)度意圖題。根據(jù)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.可知這是他們第一次把這一技術(shù)運用到這一階段，手術(shù)之前一切都進(jìn)行了模擬練習(xí)，最終結(jié)果非常好。由此內(nèi)容可知AdrianSugar對3D打印技術(shù)是很支持的。故B正確。
