There are four basic types of competition in business that form. a continuum from pure com

petition through monopolistic competition and oligopoly to monopoly. At one end of the continuum, pure competition results when every company has a similar product. Companies that deal in commodities such as wheat or corn are often involved in pure competition. In pure competition, it is often the ease and efficiency of distribution that influences purchase.

In contrast, in monopolistic competition, several companies may compete for the sale of items that may be substituted. The classic example of monopolistic competition is coffee and tea. If the price of one is perceived as too high, consumers may begin to purchase the other. Coupons and other discounts are often used as part of a marketing strategy to influence sales.

Oligopoly occurs when a few companies dominate the sales of a product or service. For example, only five airline carriers control more than 70 percent of all ticket sales in the United States. In oligopoly, serious competition is not considered desirable because it would result in reduced revenue for every company in the group. Although price wars do occur, in which all companies offer substantial savings to customers a somewhat similar tendency to raise prices simultaneously is also usual.

Finally, monopoly occurs when only one firm sells the product. Some monopolies have been tolerated for producers of goods and services that have been considered basic or essential, including electricity and water. In these eases, it is government control, rather than competition, that protects and influences sales.

Which of the following would be the best title for the passage？

A．Monopolies

B．The Commodity Market

C．The Competition Continuum

D．The Best Type of Competition

Section D

听力原文： Broadly speaking, there are two types of paintings: representational and abstract. The former portrays specific, recognizable physical objects.

For most of history, the primary purpose of painting had been to portray images. Starting with the Post-Impressionists, however, the emphasis began to shift to unconscious feeling.

There are two types of abstract paintings. "Abstracted" paintings may not look realistic, but you can get an idea of what you are looking at. "Pure" abstract paintings are just shapes, colors, lines, patterns, and so on.

In truth, there is a lot more to abstract art than what meets the eye. To truly appreciate a work of art, you need to understand there must be context involved and a particular environment created. More importantly, art allows us indirect access to our inner psyche. Great art affords a way to get in touch with the unconscious part of our existence, even if we don't realize what we are doing.

The reason abstract art has the potential to be so powerful is that it keeps the conscious distractions to a minimum. This, of course, only works if you cooperate with the artist. If you are to truly appreciate a work of art, you must be willing to let yourself go, to put yourself in the hands of the artist, so to speak, and let him take you wherever he wants.
