The traditional distinction between products that satisfy needs and those that satisfy wants is no longer adequate to describe classes of products. In today's prosperous societies the distinction has become blurred because so many wants have been turned into needs. A writer, for instance, can work with paper and pencils. These are legitimate needs for the task. But the work can be done more quickly and efficiently with a word processor. Thus a computer is soon viewed as a need rather than a want.
In the field of marketing, consumer goods are classed according to the way in which they are purchased. The two main categories are convenience goods and shopping goods. Two lesser types are specialty goods and unsought goods. It must be emphasized that all of these types are based on the way shoppers think about products, not on the nature of the products themselves. What is regarded as a convenience item in France(wine, for example) may be a specialty goods in the United States.
People do not spend a great deal of time shopping for such convenience items as groceries, newspapers, toothpaste, razor blades, aspirin, and candy. The buying of convenience goods may be done routinely, as some families buy groceries once a week. Such regularly purchased items are called staples. Sometimes convenience products are bought on impulse: someone has a sudden desire for an ice cream on a hot day. Or they may be purchased as emergency items.
Shopping goods are items for which customers search. They compare prices, quality, and styles, and may visit a number of stores be fore making a decision. Buying an automobile is often done this way.
Shopping goods fall into two classes: those that are perceived as basically the same and those that are regarded as different. Items that are looked upon as basically the same, include such things as home appliances, television sets, and automobiles. Having decided on the model desired, the customer, is primarily interested in getting the item at the most favorable price. Items regarded as inherently different include clothing, furniture, and dishes. Quality, style, and fashion will either take precedence over price, or they will not matter at all.
Specialty goods have characteristics that impel customers to make special efforts to find them. Price may be no consideration at all. Specialty goods can include almost any kind of product. Normally, specialty goods have a brand name or other distinguishing characteristics.
Unsought goods are items a consumer does not necessarily want or need or may not even know about. Promotion or advertising brings such goods to the consumer's attention. The product could be something new on the market as the Sony Walkman once was or it may be a fairly standard service, such as life insurance, for which most people will usually not bother shopping.
A word processor can be looked on as satisfying a need rather than a want if ______.
A.it is used at home to do paper work
B.it is used by a writer to type a novel
C.it becomes the only means to an end
D.a writer does not want to use it

Tile media can impact current events. As a graduate student at Berkeley in the 1960s, I re member experiencing the events related to the People's Park that were occurring on campus. Some of these events were given national media coverage in the press and on TV. I found it interesting to compare my impression of what was going on with perceptions obtained from the news media.I could begin to see events of that time feed on news coverage. This also provided me with some healthy insights into the distinctions between these realities.
Electronic media are having a greater impact on the people's lives every day. People gather more and more of their impressions from representations. Television and telephone communications are linking people to a global village, or what one writer calls the electronic city. Consider the information that television brings into your home every day. Consider also the contact you have with others simply by using telephone. These media extend your consciousness and your contact. For example, the video coverage of the 1989 San Francisco earthquake focused on "live action" such as the fires or the rescue efforts. This gave the viewer the impression of total disaster. Television coverage of the Iraqi War also developed an immediacy. CNN reported events as they happened.This coverage was distributed worldwide. Although most people were far away from these events, they developed some perception of these realities.
In 1992, many people watched in horror as riots broke out on a sad Wednesday evening in Los Angeles, seemingly fed by video coverage from helicopters. This event was triggered by the verdict (裁定) in the Rodney King beating. We are now in an age where the public can have access to information that enables it to make its own judgements, and most people, who had seen the video of this beating, could not understand how the jury (陪审团) was able to acquit (宣布……无罪) the policemen involved.Media coverage of events as they occur also provides powerful feedback that influences events. This can have harmful results, as it seemed on that Wednesday night in Los Angeles. By Friday night the public got to see Rodney King on television plea ding, "Can we all get along?" By Saturday, television seemed to provide positive feedback as the Los Angeles riot turned out into a rally for peace. The television showed thousands of people marching with banners and cleaning tools. Because of that, many more people turned out to join the peaceful event they saw unfolding on television. The real healing, of course, will take much longer, but electronic media will continue to be a part of that process.
The best title for the passage is______.
A.The 1992 Los Angeles Riots
B.The Impact of Media on Current Events
C.The 1989 San Francisco Earthquake and the 1992 Los Angeles Riots
D.How Media Cover Events
