第31题: [简答题]结果，当新的技术突破到来时就出现了问题。比如，美国的工人与德国的工人相比，要花费更长时间来掌握怎样操作新型的、灵活的制造设备，那么这些设备在德国的有效成本就比美国低：设备的正常运转需要更长时问，需要广泛的再培训，这会提高成本并产生瓶颈，限制新设备生产的速度。 参考答案:
As a result， problems emerge when new breakthrough technologies arrive．If American workers，for example，take much longer to learn how to operate new flexible manufacturing stations than workers in Germany (as they do)， the effective cost of those stations is lower in Germany than it is in the United States. More time is required before equipment is up and running at capacity, and the need for extensive retraining generates costs and creates bottlenecks that limit the speed with which new equipment can be employed.
