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
【C2】
选项
答案B
解析 由have been可知此处应填入动词分词或形容词，且能与with搭配。本句的主语“打字员、票务代理、银行出纳员……”都属于上一句提到的mid-skill jobs(中等技能工作)，本句也应该是否定这些工作。dispensed“分配；配(药)”可与with搭配，表示“免除，废弃”，符合此处语义逻辑。
