24、ively recently the opportunities for criminal activity on the Internet have been low. However, the volume of business done on the Internet is growing rapidly, and people order books and other products and makes money transactions. All this is creating temptations for hackers.Hackers are often young

But still the hackers persist often for a dare “because its there” although with what success nobody really knows.Estimates for worldwide sales on the Internet now range between $US 40 billion and $US 90

27、billion by the end of the year 2000. Much of this is in publishing and software purchases, which require the disclosure of credit card numbers, but there is really no limit to what can be conducted on the Internet.“You just dont give your credit card out to anybody,” experts say. “And in the same wa

28、y that you should regularly change your credit card access number, you can defeat hackers by regularly changing your Internet password. If you dont, its like leaving the bank vault door wide open.”When it comes to creating your password, experts recommend including a few punctuation marks and number

Next time the customer logs on to an Internet service provider the virus reveals where it is and the password to anyone who is prowling the Net looking for such information.

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

37、ate set of changes in the ocean and atmosphere across the tropical Pacific, which covers a third of the Earths circumference. Its intensity is such that it affects temperatures, storm tracks and rainfall around the world.Droughts in Africa and Australia tropical storms in the Pacific, torrential rai

38、ns along the Californian coast and the Peruvian deserts have all been ascribed to the whim of El Nino.This at least is the theory, and it has worked pretty well over the past century, with El Nino occurring about every three to five years and La Nina in between. 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). There has been only one significant La Nina, but five El Ninos, including an extremely severe one in 1982-83 that c

Moreover a huge pool of warm water has settled down near the dateline in the central Pacific.Yet it is important to understand the changes if scientists are to be able to forecast the climatic effects of El Ninos with any degree of accuracy. This is not just a

41、n academic taskaccurate forecasts can spell out feast or famine in many tropical countries around the world. Forecasting efforts have focused on El Nino, whose effects are generally more severe than those of La Nina.A worrying possibility is that the changes maybe due to greenhouse warming. If so, t

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.
