问题     The United States is widely recognized to have a private economy because privately owned business play【C1】______roles. The American free enterprise system【C2】______private ownership more than public sectors. Private businesses produce【C3】______goods and services,【C4】______almost two-thirds of the nation’ s total economic output goes to 【C5】______for personal use. The consumer role is【C6】______great, in fact, that the nation is sometimes characterized as having a "【C7】______economy".
    This emphasis【C8】______private ownership arises,【C9】______, from American beliefs about personal freedom. From the time the nation was【C10】______, Americans have【C11】______excessive government power, and they have sought to【C12】______government’ s authority over individuals—including its role in the economic realm.
     【C13】______Americans generally believe that an economy largely with private ownership is likely to operate more 【C14】______ than【C15】______with substantial government ownership. When economic forces are unfettered, Americans believe, supply and demand【C16】______the prices of goods and services. Prices, in turn, tell businesses what to produce; if people want more of particular goods than the economy is producing, the price of the goods【C17】______. That catches the attention of new or other companies that,【C18】______an opportunity to earn profits, start producing more【C19】______that goods. On the other hand, if people want less of the goods, prices fall and less competitive producers either go out of business or start producing【C20】______goods.
【C14】
选项 A、powerfully
B、efficiently
C、sufficiently
D、fundamentally
答案B
解析 考查副词辨析。空格处所在的句子意在表达“美国人将私有产权构成的经济体与公有产权构成的经济体进行比较”，又因文章主线在表达私有产权经济优于公有产权经济。powerfully“有力地”；efficiently“有效率地”；sufficiently“足够地”；fundamentally“根本地”。operate意为“运营”，因此B．efficiently为最佳选项。
