单选题 15.  Now, commercial farmers have become increasingly ______ so that almost everything consumed on most farms is now bought from outside sources rather than home-grown.
【正确答案】 C
【答案解析】 本题句意:现在,商业农民越来越专业化,所以大多数农场消费的几乎所有东西现在都是从外部来源购买的,而不是自己生产的。talented意为“有才能的,能干的”;coordinated意为“协调的”;specialized意为“专门的,专业的,专用的”;multiplied意为“使相乘,使增加,使繁殖”。故选C。
