36、d is a dramatic but mysterious climate system that periodically rages across the Pacific.El Nino means “the little boy” or “the Christ child” in Spanish, and is so called because its warm current is felt along coastal Peru and Ecuador around Christmas. But the local warming is just part of an intric

But there have been some baffling dev

39、elopments in recent years. For one thing, El Nino has returned three times in the past four years. For another, since 1976 El Nino has dominated relative to the cooler phase (La Nina).

47、produced by spending their money in the marketplace for those goods and services that they want most. Private businessmen, striving to make profits, produce these goods and services in competition other businessmen; and the profit motive, operating under competitive pressures, largely determines how

48、 these goods and services are produced. Thus, in the American economic system it is the demand of individual consumers, coupled with the desire of businessmen to maximize profits and the desire of individuals to maximize their incomes, which together determine what shall be produced and how resource

49、s are used to produce it.An important factor in a market-oriented economy is the mechanism by which consumer demands can be expressed and responded to by producers. In the American economy, this mechanism is provided by a price system, a process in which prices rise and fall in response to relative

50、demands of consumers and supplies offered by seller-producers. If the product is in short supply relative to demand, the price will be bid up and some consumers will be eliminated from the market. If, on the other hand, producing more of a commodity results in reducing its cost, this will tend to in

51、crease the supply offered by seller-producers, which in turn will lower the price and permit more consumers to buy the product. Thus, price is the regulating mechanism in the American economic system.The important factor in a private-enterprise economy is that individuals are allowed to own producti

52、ve resources(private property), and they are permitted to hire labor, gain control over natural resources, and produce goods and services for sale at a profit. In the American economy, the concept of private property embraces not only the ownership of productive resources but also certain right to d

53、etermine the price of a product or to make a free contract with another private individual.名人名言：The newspaper must provide for the reader the facts, objectively selected facts.
