20.Did you know that money is not worth the paper it is printed on?Money is really just a symbol.(31 )BLong ago,people did not use money.They made or grew food,clothes,and other things they needed.Later,people started trading.They would trade what they made to someone else in order to get different foods and goods.To trade like this is to barter(物物交換).
The barter system was a good system.Bakers could trade bread for wheat.Weavers could trade cloth for meat.Trading not just let people work at certain jobs.(32)EBut one problem with bartering was that not everyone agreed on prices.People had to work out a price each time they wanted to trade.Another problem was that the goods might be too heavy to carry.What if the cow farmer wanted to trade a cow for a horse with the horse farmer?They would have to carry their animals with them.(33)DWhat if the cow farmer wanted to trade a cow for a chicken?A cow is worth more than a chicken.The farmer should get"change."But how can you make change from a cow?
(34)APeople used to use all kinds of small things for money.They used shells,beads,feathers,seeds,and even salt.A group of people would decide the worth of a kind of shell.Other kinds of shells would be worth more or less.Then people had money that was worth a certain amount.It was easy to carry.It was easy to make change.
With time going by,we finally have the money that we use today.(35)F
