货币的历史和基本功能
Money’s got a very colourful history, because a number of things have been used in the place of what we use as money. Feathers1, shells, cloth …salt in Roman2 times when the Roman soldiers were paid in salt and that’s how we get the word salary3, from the Latin4 sal for salt.
历史上的货币五花八门。古时候，羽毛、贝壳、布料甚至盐都曾是交换工具。古罗马士兵得到的军饷就是盐。盐这个词也是英文“工资”这个词的起源。拉丁文Sal的意思是盐，英文中工资Salary就是从它演变而来的。
And a number of tribes5 used cattle6, which were useful because they were transportable7. But they were quite8 bulky9 and you weren’t always sure of the size of cattle you were going to get, so there was a problem there of quality10.
还有一些部落以牲畜作为交换媒介。这很有用，因为牲畜可以运来运去。但是它们体积庞大，而且无法确切知道你将要得到的牲畜的大小，因此存在质量方面的问题。
In the ninth century11 in China we had paper money for the first time. It wasn’t quite the paper money that we know, it was more like a piece of paper saying a promise12 to pay.
九世纪时在中国首次出现了纸币。这种纸币与我们现在使用的不同，更象是一种欠条。
And then in the seventh century we had money in the form13 of precious14 metal. There was always a problem of making sure that the coin that you got had enough precious metal in it to give it a value. When things got tough15, you often found some civilisations16 were quite good at what they called sweating the money, which was effectively17 taking out the precious metal content so that what you got actually 18wasn’t what you thought you got.
另外在七世纪时出现了贵重金属货币。但如何确切知道货币中有足够的贵重金属含量以使它具有相应的价值则一直是个问题。当时局艰难时，一些文明古国会从这种货币中提取贵重金属成份，使得货币已不再拥有你原来以为它拥有的价值。
And we have a form of that here in Australia when we had the holey19 dollar … when we had a coin with a hole in the middle because there was a shortage20 of metal.
澳大利亚就曾有过一种这类的货币，一种中间有个洞的货币。这是由于当时缺乏铸币金属的缘故。
And in those days, Spanish21 coins were used a lot. Sometimes stores used certain22 tokens23 because there was a shortage of actual coinage24. And then there is money as we know it today in notes25 and coins – plastic notes.
那时候西班牙硬币广为流通。有时商店里因为没有足够的硬币而使用一些代用币。后来就有了我们现在使用的纸钞、硬币，还有塑料钞票。
And of course, if we were doing this program in a hundred years time we might talk about quaint26 little things called money, notes and coins, because all we’d be using would be plastic card.
当然，如果我们在一百年之后再来制作这一节目，我们可能就会谈论一些奇特有趣的叫做钱、纸币或是硬币的小东西，因为到那时我们大概只使用塑料卡了。
We look at the functions27 of money. Firstly it’s a medium28 of exchange, so it’s some commodity29 which facilitates30 the exchange of goods and services.
It is also a unit of account, which means that we use money to reckon31 prices and reckon values for comparisons32 between goods and services or over time.
And thirdly, money is a store of value. It is an asset. It’s something that we can use to store value away to be retrieved 33at a later point in time. So we can not consume34 today, we can hold money instead – and transfer that consumption35 power to some point in the future.
首先货币是一种交换媒介，是帮助其他货物与服务进行交换的手段。
其次它是一种计算单位，就是说我们用钱来测量货物、服务或时间之间的价格和价值的比较。
第三它是价值存储手段，是一种资产。我们可以用它把价值储存起来，在以后的某个时刻再取回。这样我们不必现在就把它用掉，而是可以存着钱，把这种消费能力转移到将来的某个时刻。
