OED解释道,这个add oil源自香港英文,主要也是香港英文的说法(originally and chiefly Hong Kong English),用以表达鼓励、激励、或支持(expressing encouragement, incitement, or support),相当于英文的“go on!”或“go for it!”。
“If we really are serious about being Asia’s World City, we still have a lot of work to do. So add oil, everyone!(要想成为亚洲的世界级城市,如果我们真的是玩真的话,那么我们还有很多的工作要做。所以各位,加油!)
