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】________.
【C2】
选项
A、Likewise
B、Furthermore
C、Therefore
D、Instead
答案
D
解析
由上句的it is not simply that(不只是……)和本句的it is…that(是……)这两个强调句型及语义可判断本句承接上句继续进一步阐述作者的观点。两句之间应为转折关系,所以选D项Instead“(不是……)而是……”。A项Likewise“同样地”表示类比。B项Furthermore “而且,此外”表示递进,C项Therefore“所以”表示因果,均不能和not simply构成语义呼应。
