Peek through the inspection windows of the nearly 100 three-dimensional (3D) printers quietly making things at RedEye, a company based in Minnesota, and you can catch a glimpse of how factories will work in the future. It is not simply that the machines run day and night【C1】________by just a handful of technicians.【C2】________it is what they are making that shows how this revolutionary production process is【C3】________the manufacturing mainstream.
3D printers make things by building them up, a layer at a time,【C4】________a particular material, rather than【C5】________it by cutting, drilling or machining—which is why the process is also called additive manufacturing. There are many ways in which this can be done, and with only a【C6】________adjustment of software each item can be different,【C7】________the need for costly retooling of machines. This has made 3D printing a【C8】________way to make one-off items, especially prototype parts, mock-ups, small mechanical【C9】________and craft items.
And that is about all that 3D printers are good for,【C10】________the doubters. Chief among them is Terry Gou, the boss of Foxconn. He thinks 3D printing is just "a trick" without any【C11】________value in the manufacture of real finished goods, and he has vowed to start spelling his name backwards if【C12】________wrong.
Mr. Gou is right about one thing: additive manufacturing is not about to replace mass manufacturing.【C13】________the technology is improving, the finish and durability of some printed items can still【C14】________what producers require. And nor can 3D printers produce millions of【C15】________parts at low cost, as mass-production lines can.【C16】________3D printers have their【C17】________which is why they are starting to be used by some of the world’s biggest manufacturers, such as Airbus, Boeing, GE, Ford and Siemens.
The market for 3D printers and【C18】________is small, but growing fast. Last year it was worth $2.2 billion worldwide, up 29% from 2011. As producers become more【C19】________with the technology, they are moving from prototypes to final【C20】________.
【C6】
选项
A、delicate
B、fine
C、major
D、surprising
答案
B
解析
空格句表达的是3D打印技术的制作优势。根据空格前的限定词only可推测所做的adjustment应该很容易做到。否则无法体现其优势。B项fine可表示“细微的”,表明只要对软件稍作调整。便可生产不同产品。A项delicate“纤细的,精细的“不能修饰adjustment。C项major和adjustment搭配表示“重大调整”,无法体现其优势。D项surprising“令人惊讶的”和限定词only搭配语义不通顺。
