for gas in the small town of Havana, Ill. We began walking to the distant station with our empty five-gallon cans when we passed three construction workers taking a break. "You fellows coming from the river？" one asked.

"You bet. Gotta gas up," Mark said.

We had only gone a few feet past them when one of them hollered (叫喊)."Hey, take my truck." Then he pointed to the vehicle at the curb and tossed us the keys. The man didn't even know our names.

We did borrow the truck. We got our gas, returned the vehicle and talked a few minutes with the owner. His name was Bill Parsley, and he was the sort of friendly, open man who would tell a couple of strangers to take his truck.

Take my truck. It became like a mantra (祷文)to us. It represented the world as it should be.

This past February, as Mark and his son were driving near their home in St. Louis, they came upon a van barely moving. The problem was an exhaust system dragging on the ground. Sparks were flying.

A young woman was at the wheel, and she had a baby in a car seat. Mark stopped and offered to follow her to a gas station to make sure she got there safely. Then he drove her to a nearby mall, where he picked up her waiting husband and son, and returned them all to the gas station. Bad news awaited them: the mechanic couldn't get the van fixed until morning.

The husband thanked Mark and said he'd call a taxi. My friend lives near the gas station. "Take my car," he said, handing over the keys. The man was taken aback. "Do you even know my name？" he asked.

"Actually, I don't," said Mark. "Just bring the car back tomorrow."

After a few protestations, the family climbed into the car and drove away. Less than an hour later the grateful man, followed by his wife in the family's other car, returned Mark's vehicle.

As Mark watched the couple drive off, he felt good. He turned to his wife, Carol and said, "We just paid Bill Parsley back."

. Three basic ways may be described as the market system, the administered system, and the traditional system.

2 In a market system individual economic units are free to interact among each other in the marketplace. 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, shorts, 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.

3 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 good 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.

4 In a traditional society, production and consumption patterns are governed by tradition；every person's place within the economic system is fixed by parentage, religion, and custom. 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.
