问题     Rather than using custom machine tools to build early models of new parts, Ford is now using 3-D printing technology to design and test its engineers’ latest ideas. The new method allows product developers to have a【C1】______in their hands in as little as a week after they create a new design— compared with having to wait three to four months【C2】______"We’re building more and more parts every day using this【C3】______,"says Harold Sears, a technical expert in rapid manufacturing at Ford’s design facility in Dearborn, Mich. Ford’s new hybrid transmission was developed on a 3-D printer that costs about $300,000 and which can turn a pile of aluminum powder into a working prototype in a day or two.
    While low-cost 3-D printing by consumers and small businesses looks like a market now ready for takeoff, large businesses have already【C4】______advanced versions of the technology. The result has been a【C5】______improvement in the product-development process across a wide range of industries, including the【C6】______of cars, consumer electronics, safety equipment and medical devices.
    The process has done more than just save time and money. Engineers say rapid prototyping using 3-D printing is producing more【C7】______higher-quality products—from custom-fitted bicycle helmets to better-sounding ear buds and loudspeakers.
    Instead of waiting for tools and parts to come back from outside machine shops or injection-molding houses, product developers on tight【C8】______now get more hands-on time to test their models. 3-D printers allow them to test and【C9】______more versions of their prototypes—in some cases tripling the number of duplicates of a new product that can be【C10】______before being produced on a large scale.
    A)previously B)thereafter C)process D)elastic
    E)deadlines F)manufacturing G)significant H)innovative
    I)ignited J)embraced K)lubricate L)prototype
    M)refined N)update O)mechanisms
【C2】
选项
答案A
解析 此处需填入副词，修饰have to wait….根据本句内容可知，有了3-D打印技术之后，等待模具的时间大大缩短，而不像“以前”要等3、4个月，可见此处应选用previously。
