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.
【C14】

选项 A、differently
B、enormously
C、completely
D、impressively

答案B

解析 空格处前面是动词varied,根据上下文语义判断,这里的意思应该是说“公司之间在投资技术方面的意愿相差很大”,有的公司愿意在这方面投资,有的公司则宁愿投资股票。[A]选项differently首先可以排除,它不能和vary一词搭配。[B]选项enormously表示“巨大地”。[C]选项completely表示“完全地”,词义过于绝对。[D]选项impressively表示“令人印象深刻地”,用在这里也不恰当。因此,正确答案应选[B]。
