It is not just that they are supporting a relatively dirty version of ethanol ( far better to import brazil ' s sugar - based liquor ) ; they are also offsetting older grain subsidies that lowered prices by encouraging overproduction 这不仅仅是在支持一个乙醇的相对肮脏的版本（比进口巴西的基于糖的燃料要好得多了） ；他们也是在抵消更老的谷物补贴的作用，该补贴通过鼓励生产过剩降低了价格。

It is not just that they are supporting a relatively dirty version of ethanol ( far better to import brazil ' s sugar - based liquor ) ; they are also offsetting older grain subsidies that lowered prices by encouraging overproduction 一方面，该政策补贴的是相对说来更不环保的乙醇品种（进口以蔗糖为原料的巴西产乙醇则好得多） ；另一方面，该政策抵消了过去通过鼓励过剩生产从而降低价格的谷物补贴政策。
