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 sys tem.
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 mar ket 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 ad ministering 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: parent age, 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.
What is the main purpose of the passage？
A．To outline contrasting types of economic systems.
B．To explain the science of economics.
C．To argue for the superiority of one economic system.
D．To compare barter and money-exchange markets.

There are different ways in which people try to deal with the problem of energy. One way is the greater production of common energy sources, such as coal, oil and gas. The trouble with these sources, however, is that they are not renewable.
Another way is energy conservation (节能 ), which means using energy more efficiently (有效地 ). In some very cold countries people build special houses to save energy. They place materials between the inside and the outside of the walls of the house to keep the cold out and the warmth in. The house is heated by the lights, the body heat of the people and the other equipment in it.
Finally, renewable energy sources are used even though they are often expensive to develop. One form. of these is geothermal energy. In certain parts of the world the temperature of the earth increases thirty degrees centigrade with each kilometer down. At six kilometers, therefore, it rises to nearly two hundred degrees. To get the heat, water is pumped (压;抽 ) down into the rocks and back up to the surface. Heat from the earth is already used in certain countries.
