【題目】Quicker and faster 3-D printers have allowed not just amazing objects to be created, but have started to affect how doctors treat patients.

We’ve put together a list of some of the most amazing medical breakthroughs made possible with 3-D printing.

Life-Saving Airway

In 2013, doctors created a new airway for kaiba Gionfriddo, a boy born with an airway that kept collapsing (萎陷). To save his life doctors printed tiny tubes to join together in different shapes and sizes until one finally worked for Kaiba. It was placed in Kaiba’s bronchus (支氣管) so that it no longer collapsed. Even more remarkably, once the plant was placed it could stay 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 used is as a way to create prosthetics (假肢). A boy born without an arm named Alex was able to get a new“bionic”hand thanks to it. Last year a college student spent 8 weeks coming up with a special prosthetic design that only cost a few hundred dollars in materials. He said he wanted to create a prosthetic far cheaper than other choices that can run tens of thousands of dollars.

A practice Heart

In Seattle, doctors have been able to use 3-D printing technology to“practice”risky operations so that they will face fewer surprises in 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 truly one-of-a-kind,”Dr. Stephan Seslar, a heart disease specialist said. “Operating on 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 to a 3-D printer. Stephen Power broke his cheek bones in a crash. To help Power his doctors instead created 3-D bones all carefully printed in the shape of his face. “This is really the first time we’ve taken it to this stage, where everything has been planned and modeled in advance — and worked sweetly,”said Adrian Sugar, a doctor.

【1】What is special about the 3-D printed airway?

A．It uses high-tech materials.

B．It varies in shapes and sizes.

C．It can be absorbed by the body.

D．It can prevent any disease in the airway.

【2】What is the advantage of the new“bionic”hand?

A．Its price. B．Its effects.

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.

【答案】

【1】C

【2】A

【3】C

【4】B

【解析】

試題分析：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(gè)具體的病例。

【1】C 細(xì)節(jié)理解題。根據(jù)第四段最后兩句Even more remarkably, once the plant was placed it could stay there. It’s designed 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(xiàng)內(nèi)容正確。

【2】A 細(xì)節(jié)理解題。根據(jù)第六段第三句Last year a college student spent 8 weeks coming up with a special prosthetic design that 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(fèi)的錢很少。所以這種仿生手的優(yōu)勢是價(jià)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 truly one-of-a-kind,”Dr. Stephan Seslar, a heart disease specialist said. “Operating on her without understanding the structure of her heart better could be very dangerous.”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“This is really the first time we’ve taken it to this stage, where everything has been planned and modeled in advance — and worked sweetly,”said Adrian Sugar, a doctor.可知這是他們第一次把這一技術(shù)運(yùn)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Adrian Sugar對3D打印技術(shù)是很支持的。故B正確。

Nearly five years before, and with the help by our father, my sister and I planted

Some cherry tomatoes(圣女果)in our back garden. Since then for all these year we

had been allowing tomatoes to self-seed where they please. As result, the plants are

growing somewhere. The fruits are small in size,but juicy and taste. There are so much

that we often share them with our neighbors. Although we allow tomato plants to grow

in the same place year after year, but we have never had any disease or insect attack

problems. We are growing wonderfully tomatoes at no cost!
