|第1、2、3、4、5题：There are various ways in which individual economic units can interact with one|
another.Three basic ways may be described as the market system,the administered
system and the traditional system.
In a market system individual economic units are free to interact among each other in the market place.It is possible to buy commodities from other economic units or sell commodities to them.In a market,transactions may take place via barter or money exchange.In a barter economy,real goods such as automobiles,shoes,and pizzas are traded against each other.Obviously,finding somebody who wants to trade my old car in exchange for a sailboat may not always be an easy task.Hence,the introduction of money as a medium of exchange eases transactions considerably.In the modern market economy,goods and services are bought or sold for money.
An alternative to the market system is administrative control by some agency over all transactions.This agency will issue edicts or commands as to how much of each goods and service should be produced,exchanged,and consumed by each economic
unit.Central planning may be one way of administering such an economy.The central plan,drawn up by the government,shows the amounts of each commodity produced by the various firms and allocated to different households for consumption. This is an example of complete planning of production,consumption,and exchange for the whole economy.
In a traditional society,production and consumption patterns are governed by tradition:parentage,religion,and custom fix every person's place within the economic system.Transactions take place on the basis of tradition,too.People belonging to a certain group or caste may have an obligation to care for other persons,provide them with food and shelter,care for their health, and provide for their education.Clearly,in a system where every decision is made on the basis of tradition alone,progress may be difficult to achieve.A stagnant society may result.
