原文：市场经济取代计划经济，极大地解放了生产力。译文：The market economy has replaced the planned economy,and it has greatly liberated the productive forces.改译：
【正确答案】：The replacement of planned economy with market economy has greatly liberated the productive forces.【解析】原译文没有恰当运用词类转换来体现英语本身的特点。英语多用抽象名词作主语，因此原句的动词“取代”可用其同源名词replacement代替并作主语，使写出的英语句子更地道。
