问题     Innovation, the effective recipe of progress, has always cost people their jobs. Over the past 30 years the digital revolution has【C1】______ many of the mid-skill jobs that supported 20th-century middle-class life. Typists, ticket agents, bank tellers and many production-line jobs have been【C2】______ with.
    For those who believe that technological progress has made the world a better place, such change is a natural part of rising【C3】______ . Although innovation kills some jobs, it creates new and better ones, as a more productive society becomes richer and its wealthier inhabitants【C4】______ more goods and services. A hundred years ago one in three American workers was employed on a farm. Today less than 2% of them produce far more food. The millions freed from the land were not delivered to joblessness, but found better-paid work as the economy grew more【C5】______ . Today the pool of secretaries has【C6】______ , but there are ever more computer programmers and web designers.
    Optimism remains the right starting-point, but for workers the dislocating (扰乱的) effects of technology may make themselves evident faster than its benefit. Even if new jobs and【C7】______ products emerge, in the short term income gaps will widen, causing huge social dislocation and perhaps even changing politics. Technology’s impact will feel like a tornado, hitting the rich world first, but【C8】______ sweeping through poorer countries too. Worse, it seems likely that this wave of technological【C9】______ to the job market has only just started. From driverless cars to clever household devices, innovations that already exist could destroy jobs that have【C10】______ been untouched.
A) prosperity E) partition I) conversely M) demand
B) dispensed F) eventually J) shrunk N) complicated
C) inquire G) sophisticated K) fragile O) hitherto
D) wonderful H) displaced L) disruption
【C6】
选项
答案J
解析 此处应填入谓语动词，由has可知是过去分词。本句与秘书职位总数(the pool of secretaries)相关，下文but转折提到计算机程序员和网页设计师越来越多，故此处需填入与more语义相反的词，shrunk“收缩”符合。
