第2段
1 .<-FEMALE PROFESSOR:-> So, let's talk about money.
所以，下面让我们来说一说货币。
2 .What is money?
什么是货币？
3 .Well, typically people think of coins and paper "bills" as money ...but that's using a somewhat narrow definition of the term.
呃，通常情况下，人们会想到硬币，以及纸币。但是，这里用的是货币的狭义定义。
4 .A broad definition is this:[slowly] money is anything that people can use to make purchases with.
广义上的定义是：货币是任何人们可以用来购买其他物品的物品。
5 .Since many things can be used to make purchases, money can have many different forms.
由于很多东西都可以用来购买东西，所以货币可以有很多不同的形式。
6 .Certainly, coins and bills are one form of money.
可以确信的一点是，硬币和纸币都是货币的一种形式。
7 .People exchange goods and services for coins or paper bills, and they use this money, these bills ...to obtain other goods and services.
人们通过交换物品或者服务来获取硬币或者纸币，然后他们又用这些货币，这些纸币去换取别的物品以及服务。
8 .For example, you might give a taxi driver five dollars to purchase a ride in his taxi.
举个例子，你付给的士司机5美元，用以购买坐他车行驶的一段路程。
9 .And he in turn gives the five dollars to a farmer to buy some vegetables.
然后，他把这五美元付给了某位农民，用以购买一些蔬菜。
10 .But, as I said, coins and bills aren't the only form of money under this broad definition.
但是就像我之前提到过的那样，硬币和纸币只是在广义定义下，货币的一种形式。
11 .Some societies make use of a barter system.
在一些社会体系中，人们使用的是物物交换制。
12 .Basically, in a barter system people exchange goods and services directly for other goods and services.
基本上，在物物交换体系中，人们直接用物品或者服务来换取其他的物品或者服务。
13 .The taxi driver, for example, might give a ride to a farmer in exchange for some vegetables.
举个例子，的士司机给捎农民一程，用以交换一些蔬菜。
14 .Since the vegetables are used to pay for a service, by our broad definition the vegetables are used in barter as a form of money.
因为蔬菜在这里是用以支付乘车服务的，所以在广义下，蔬菜是物物交换系统里一种形式的货币。
15 .Now, as I mentioned, there's also a second ... a narrower definition of money.
现在，就如我之前提到的第二种，货币的更为狭义的定义。
16 .In the United States only coins and bills are legal tender—meaning that by law, a seller must accept them as payment.
在美国，只有硬币和纸币才是合法的货币。意思是，在法律规定下，卖方必须接受通过它们完成支付行为。
17 .The taxi driver must accept coins or bills as payment for a taxi ride.
出租车司机必须接受用硬币或者纸币来支付打的的费用，
18 .OK?
对吧？
19 .But in the U.S., the taxi driver is not required to accept vegetables in exchange for a ride.
但是在美国并没有要求出租车司机接受用蔬菜交换行程的支付方式。
20 .So a narrower definition of money might be whatever is legal tender in a society, whatever has to be accepted as payment.
所以，货币的狭义定义是指，在社会中，只要是合法的，能被接受的物品都能称之为货币。
