Almost every new innovation goes【C1】______three phases.【C2】______initially【C3】______into the market, the process of【C4】______is slow. The early models are expensive and hard to use, and perhaps even unsafe. The economic【C5】______is relatively small. The second phase is the explosive one,【C6】______the innovation is rapidly adopted by a large number of people. It gets cheaper and easier to use and becomes something familiar. And then in the third【C7】______,【C8】______of the innovation【C9】______again,【C10】______it permeates out across the economy.
During the explosive phase, whole new industries spring up to produce the new product or innovation, and to【C11】______it. For example, during the 1920s, there was【C12】______dramatic acceleration in auto production, from 1.9 million in 1920 to 4.5 million in 1929. This【C13】______was accompanied【C14】______all sorts of other essential activities necessary for an auto-based nation: Roads had to be built for the cars to【C15】______; refineries and oil wells, to provide the gasoline; and garages, to repair【C16】______. Historically, the same【C17】______is repeated again and again with innovations. The construction of the electrical system【C18】______an enormous early investment in generation and distribution【C19】______. The introduction of the radio was followed by a buying spree by Americans that quickly brought radios into almost half of all【C20】______by 1930, up from nearly none in 1924.
【C20】
选项
A、houses
B、households
C、homes
D、families
答案
B
解析
词义辨析题.house指单纯的房子,与人无关;home具有情感指向,指家庭给人以归宿感;household“家户”,是指住在同一套/个住宅里的人,不管是否有亲缘关系;family“家庭”,不仅要住在一起,还要有亲缘关系。一般统计者认为:住在一起,可以共享生活物品(这些物品里的最大项就是房子),共同承担生活费用,更像是一个基本的经济单元。因此,更倾向于采用household这个定义来统计收入。此处指一半以上的家庭购买了收音机,故选B。
