To return to port without a single barrel of oil would be a mistake, sir.

没带任何鱼油返航非明智之举。

So in a sense, the economic activity of billions of people is reflected in the price of a single barrel of crude.

所以从某种意义上说, 一桶原油的价格反映着数十亿人的经济活动。

A single barrel of oil contains the energy equivalent of the work of five to 10 people.

一桶油所含的能量相当于 5 到 10 个人的工作量。
