　　[长难句突破]

　　The American economic system is organized around a basically private-enterprise, market-oriented economy in which consumers largely determine what shall be produced by spending their money in the marketplace for those goods and services that they want most.

　　主体句式：The American economic system is organized around a economy.

　　结构分析：本句结构较为复杂，重点在于抓住主干，然后逐步分析其细枝末节。Economy后面的which引导的定语从句用来修饰economy，这个从句中的主干是consumers determine what shall be produced。“what shall be produced”后面的分词结构是一个由by引导的状语，句末的定语从句that they want most 修饰goods and services。需要注意的是本句主要围绕着economy这个词语展开。

　　If, on the other hand, producing more of a commodity results in reducing its cost, this will tend to increase the supply offered by seller-producers, which in turn will lower the price and permit more consumers to buy the product.
