The Father of 3D Printing

About twenty years ago, the surgeons at the Wilford Hull medical center working to separate a pair of conjoined(连体的) twins thought that only one would be able to walk after the operation. After a model of the girls’ bone structure was 【1】 using 3D printing, however, they found a shared upper leg bone to be bigger than expected and split it successfully, 【2】 in both twins being able to walk. Now eighty and still working as chief technology officer of 3D Systems. Chuck Hull is enjoying some minor 【3】 31 years after he first printed a small black eye-wash cup using a new method of manufacturing known as 3D printing.

At the time, he was working for a company that used UV light to put thin layers of plastic coats on tabletops and 【4】. He had an idea that if he could place thousands of thin layers of plastic on top of each other and then cut their shape using light, he would be able to form three dimensional objects. After a year, he 【5】 a system where light was shone into a bottle of photopolymer – a material which changes from liquid to plastic-like solid when light shines on it – and traces the shape of one level of the object. Subsequent layers are then printed until it is 【6】.

After patenting the invention, he set up 3D Systems, 【7】 getting $6m (3.5m) from a Canadian investor. The first 【8】 product came out in 1988 and proved a hit among car manufacturers, in the aerospace sector and for companies designing medical equipment. The possibilities appear endless – from home-printed food and medicine to 【9】 that pictures of objects be able to be taken in shops and then recreated using plans downloaded from the Internet Although deliberate in his responses, there is one moment when the 【10】 spoken Chuck Hull tells of his surprise about what exactly his creation was capable of achieving.

【解析】

本文是一篇人物介绍。本文主要介绍了对技术影响深远的3D打印之父——查克·赫尔。

【1】考查动词。根据前面的was可知，这里用动词的过去分词形式。句意：使用3D打印生成女孩骨骼结构模型后。故选A。

【2】考查短语。短语result in结果，在句中作结果状语，表示自然而然的结果，故用现在分词、句意：他们发现两人共用的一根大腿骨比预想中更大，并成功将其分开，结果两个孩子都能走路了。故选D。

【3】考查名词。根据前面的形容词minor可知，后接名词形式。句意：31年前，他首次利用一种被称为立体平面印刷术的新制作方法，既现在所知的3D打印技术，打印出一个小小的黑色眼药水杯，查克·赫尔由此小有名气。故选C。

【4】考查名词。这里与前面的名词tabletops并列。句意：那时，他就职于一个利用紫外线把薄薄的塑料饰面层置于桌面和家具表面的公司。故选B。

【5】考查动词。分析句子可知，句中缺少谓语动词，根据文章可知用一般过去时。句意：一年后，他发明了一种方法。故选F。

【6】考查动词。根据前面的is可知，这里用过去分词形式。句意：然后再把随后的几层打印上去，直到最后完成。故选H。

【7】考查副词。根据句意可知，这里用副词修饰整个句子。句意：这项发明申请专利后，他创立了3D系统公司，最终从一位加拿大投资者那里获得了600万美元（350万英镑）的投资。故选G。

【8】考查形容词。修饰名词product，用形容词修饰。句意：首件商业化产品于1988年出炉。故选J。

【9】考查名词。介词to后接名词形式。句意：这种技术可利用的价值似乎是无穷的——从家用打印食品和药品，到从商店里拍下瓷器的照片，然后用从互联网上下载的图纸重新制作的建议。故选E。

【10】考查副词。修饰过去分词spoken，前用副词形式。句意：尽管他的反应审慎持重,但有那么一刻, 轻声细语的查克·赫尔还是显出了他对自己的发明到底能够取得什么样的成果感到吃惊。故选K。
