听力原文： Mass media is the term used to denote, as a class, that section of the media specifically conceived and designed to reach a very large audience. It emerged in the 1920s with the advent of nationwide radio networks and of mass-circulation newspapers and magazines.

Media is a contraction of the term media of communication, referring to those organized means of dissemination of fact, opinion, and entertainment such as newspapers, magazines, cinema films, radio, television, and the World Wide Web.

During the 20th century, the advent of mass media was driven by technology that allowed the massive duplication of material at a low cost. Physical duplication technologies such as printing, record pressing and film duplication allowed the duplication of books, newspapers and movies at low prices to huge audiences. Television and radio allowed the electronic duplication of content for the first time.

In a democratic society, an independent media serves to educate the public about issues regarding government and corporate entities.

During the last decade of the 20th century, the advent of the World Wide Web marked the first era in which any individual could have a means of exposure on the scale of mass media.

[A] For example, the United States is a major consumer of coffee, yet it does not have the climate to grow any of its own. Consequently, the United States must import coffee from countries (such as Brazil, Colombia and Guatemala) that grow coffee efficiently. On the other hand, the United States has large industrial plants capable of producing a variety of goods, such as chemicals and airplanes, which can be sold to nations that need them. If nations traded item for item, such as one automobile for 10,000 bags of coffee, foreign trade would be extremely cumbersome and restrictive. So instead of barter, which is the trade of goods without an exchange of money, the United States receives money in payment for what it sells. It pays for Brazilian coffee with dollars, which Brazil can then use to buy wool from Australia, which in turn can buy textiles from Great Britain, which can then buy tobacco from the United States.

[B] Foreign trade also occurs because a country often does not have enough of a particular item to meet its needs. Although the United States is a major producer of sugar, it consumes more than it can produce internally and thus must import sugar.

[C] Foreign trade, the exchange of goods between nations, takes place for many reasons. The first, as mentioned above is that no nation has all of the commodities that it needs. Raw materials are scattered around the world. Large deposits of copper are mined in Peru and Zaire, diamonds are mined in South Africa and petroleum is recovered in the Middle East. Countries that do not have these resources within their own boundaries must buy from countries that export them.

[D] In today's complex economic world, neither individuals nor nations are self-suffi-cient. Nations have utilized different economic resources; people have developed different skills. This is the foundation of world trade and economic activity. As a result of this trade and activity, international finance and banking have evolved.

[E] Finally, foreign trade takes place because of innovation or style. Even though the United States produces more automobiles than any other country, it still imports large numbers of autos from Germany, Japan and Sweden, primarily because there is a market for them in the United States.

[F] For most nations, exports and imports are the most important international activity. When nations export more than they import, they are said to have a favorable balance of trade. When they import more than they export, an unfavorable balance of trade exists. Nations try to maintain a favorable balance of trade, which assures them of the means to buy necessary imports.

[G] Third, one nation can sell some items at a lower cost than other countries. Japan has been able to export large quantities of radios and television sets because it can produce them more efficiently than other countries. It is cheaper for the United States to buy these from Japan than to produce them domestically. According to economic theory, Japan should produce and export those items from which it derives a comparative advantage. It should also buy and import what it needs from those countries that have a comparative advantage in the desired items.
