or even pizzas—just with pressing a single button. It may sound like something out of【M1】________
science fiction, but it’ s increasing becoming a reality. Thanks to 3-D printing, 【M2】________
companies are reimaging their long-term business plans.
Invented in mid-1980s, 3-D printers create solid, three-dimensional objects【M3】________
from various materials such as plastic, wax, wood, gold, or titanium. A major advantage of
3-D printing is that designs for objects can be easily changed. When designs were changed in traditional【M4】________
manufacturing, the machinery that make the objects needs to be redesigned or upgraded, 【M5】________
which can be very cost. But in the case of 3-D printers, only the software needs to be modified.【M6】________
3-D printing is also better than traditional manufacturing because there is no wasted【M7】________
material. With traditional manufacturing, some material is cut away from to create an object, 【M8】________
but 3-D printing uses only which is necessary. Guided by software, a 3-D printer builds【M9】________
an object one layer at a time, place material only where it needs to be. As a result, 【M10】________
it can make complex objects less expensively. [br] 【M4】
选项
答案
Were→are
解析
该句的意思是“当传统制造中的设计发生变化时,制造物体的机器需要重新设计或升级,这可能非常昂贵”。根据整篇短文的时态可知,此处时态应该用一般现在时,因此需将were改为are。
