问题    从通常的定义上说,货币是交换的媒介。也就是说,你收到的钱是用你所做的工作换取的。反过来,你把钱给别人以换取你需要的东西,如食物、衣服或其他消费品。各种各样的物品曾经被用作货币。在有些地方,贝壳曾被用作交换媒介。然而,多年来,最普通的几种货币是金、银或铜。今天,大多数地方的硬币仍然是用银或铜铸造的。但是,世界上大部分货币是用本身几乎没有任何价值的纸做的。

选项

答案 Money is usually defined as medium of exchange. That is, you receive money in exchange for the work you do. In turn, you give it to people in exchange for the things you want, such as food, clothing, or other consumer goods. Many different things have been used as money. In some places, seashells have served as a medium of exchange. However, gold, silver, and copper have been the most popular kinds of money throughout the ages. Coins are still made of silver and copper in most places today. However, most of the world’s money is made of paper, which has almost no value in itself.
