Let the concoction sit for about eight hours ___2___ it separates into two layers. The darker bottom part is unusable. The top, ___3___, is fuel.
您的车子没油了吗？把加油站忘了吧，不妨改到厨房看看。您只需要植物油、碱液、防冻剂，以及一台搅拌机。首先，将防冻剂与碱液混合。混合物产生泡沫后，便可进行下一步骤。现在倒入植物油，以搅拌机将一切打匀，然后静置约八小时，直到溶液分离成两层为止。颜色较深的底层不能使用，而上层则是燃料。

This may sound like a strange way to power something, but it worked. The US is now making plans to ___7___ 75% of all the crude oil imported from the Middle East with biofuel by 2025. The future of biofuel looks very bright!
事实上，生质燃料的使用并非新概念。德国发明家鲁道夫．狄瑟尔是第一位想出这个主意的人。1897年，鲁道夫研发出一种用花生油运转的引擎，听来或许奇怪，但是引擎真的能够运转。美国目前正在拟定计划，希望在2025年之前以生质燃料取代75%的中东进口原油。看来生质燃料的前景可是一片光明。
