问题     Everyone complains that corporate America is【C1】______to hire additional workers. Far【C2】______attention has been paid to the flip side of the jobless recovery: the【C3】______improvement in American productivity.
    When the economy【C4】______in 2008, there was little of the fall in labor productivity that normally【C5】______a recession, and this was not just a one-off "batting average" effect (in which average productivity rises because the worst performers are fired). Rather, it was a productivity boost that has continued【C6】______expert predictions that workers can only be【C7】______so hard for a short while.
    In the third quarter of 2011, American labor productivity was 2.3% higher than in the same period a year earlier. Manufacturing productivity in that quarter rose by 2. 9% compared with a year earlier. America’s productivity growth has been more【C8】______than most other rich countries’—a feat【C9】______to its flexible labor market and a culture of enterprise.
    Two things could keep productivity rising. First, workers are terrified of losing their jobs. This makes it easier to persuade them to put in extra hours or【C10】______new tasks. Second, tough times are forcing firms to【C11】______every brain cell to become more efficient. Sealed Air, for example, has made numerous incremental tweaks, such as【C12】______a machine that makes absorbent pads for supermarket meat trays so that its output increased from 400 units per hour three years ago to 550—with the same number of workers.
    The【C13】______of firms to invest in such enhancements has varied【C14】______. Some would rather hoard cash or buy back their own shares【C15】______spend it on more efficient machinery or information technology. Yet there are【C16】______that leading industrial firms are starting to increase their capital spending, says Jeff Sprague of Vertical Research Partners, a research outfit. In particular, he has noticed firms investing in "debottlenecking" which,【C17】______its name suggests, means removing hold-ups in production processes, sometimes with an additional production line.
    【C18】______short, the recession has forced American firms to become more muscular. This should help them【C19】______when the good times return. It should also give them an edge【C20】______foreign rivals.
【C12】

选项 A、upgrading
B、repairing
C、reusing
D、recovering

答案A

解析 前文说公司绞尽脑汁提高生产率,下面用Sealed Air公司的例子说明问题。该公司通过各种各样的办法提高生产率,例如:它对制造超市里面的肉类托盘的吸水垫的机器进行了调整,使它的生产率从三年前每小时生产400个单位提升为每小时生产550个单位。amachine前填一个动词,表示使这种机器的生产率提升,四个选项中[A]选项upgrading最为贴切。
