汽油

It baffles me that President Bush would rather go to Saudi Arabia twice in four months and beg the Saudi king for an oil price break than ask the American people to drive 55 miles an hour, buy more fuel-efficient cars or accept a carbon taxor gasoline tax that might actually help free us from what he called our "addiction to oil."

一直令我困惑不解的是布什总统宁可在四个月中两度造访沙特阿拉伯，乞求沙特国王降低石油价格，也不愿意敦促美国民众以时速55英里的速度驾车，购买更多节油轿车，接受烟尘排放税或汽油税，而这些举措或许真的可以帮助我们从被布什总统称之为&对石油的嗜好&中解脱出来。
