例312　Thus, in the American economic system it is the demand of individual consumers, coupled with the desire of businessmen to maximize profits and the desire of individuals to maximize their incomes, that together determine what shall be produced and how resources are used to produce it.

【结构分析】这句话是典型的强调句，被强调的成分有三个，第一个是the demand of individual consumers，第二个是the desire of businessmen to maximize profits，第三个是the desire of individuals to maximize their incomes，后面加上强调句that together determine...，里面套上两个并列的宾语从句，也就是what shall be produced and how resources are used to produce it。

【亮点回放】此句话的亮点是三个强调成分的精确使用，而且还套上两个宾语从句。

【核心词汇】

demand of individual consumers　个体顾客的需求

maximize profits　利润最大化

maximize their incomes　收入最大化

what shall be produced　所生产的东西

【参考译文】所以说，在美国经济体系中，正是消费者的需求，伴随着商人让利润最大化和消费者让收入最大化的需求决定所生产的东西以及生产资料如何调配来生产这些东西。
