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 (折扣 ) 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 cases, 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

Asimov was one of the leading writers of Western science fiction's Golden Age, so although his writing may not have a direct influence on writers of today, his underlying (潜在的) influence on many levels is undeniable — the famous Three Laws of Robotics, and many classic writing techniques, for example. Of course, his influence is related to the atmosphere that existed in the Golden Age; a science fiction writer today has a hard time reaching that level no matter how outstanding he or she is. Asimov's novels are marked by a fully integrated logical system, and his stories are a pleasure to read — this is the reason his novels still attract readers today. Naturally, Western science fiction has few people these days who follow Asimov' s creative methods; instead they are closely connected to mainstream artistic trends, employing large amounts of postmodern techniques. This type of science fiction has a hard time blossoming on Chinese soil. The majority of Chinese SF readers would rather read the classic works of Asimov. This is an important question that faces today' s Chinese science fiction writers.
Compared with the "Robot Series", Asimov's "Foundation Series" is a little less well-known in China. This is mostly due to the large influence of the Three Laws, and moreover, the Founda-tion novels have never been completely introduced here. In fact, the Foundation series creates an entire world, even grander than that of the "Robot Series"; this science fiction epic(史诗) had a direct influence on later Western science fiction, the most famous example being Star Wars.

It has also provided the basis for the traditional methodology of science. It includes objective observation, description of some phenomena, the statements of hypotheses(假说) about the events observed and possible relationships among them, the use of these to predict future events, the evidence of the hypotheses and the construction of a theory based on the evidence of the hypotheses.
But the classic "scientific method" has been criticized from a variety of points. To begin with, it is obvious that the "objectivity" of science strictly characterizes only the lowest order of scientific activity—observation. Even here it is doubtful whether anyone can be a truly impartial observer of events.
What someone chooses to observe and the way one observes it must, after all. in part be a reflection of experience and of ideas as to what is important. Consider, for example, the different ways in which an artist and a layman look at a painting and the different reactions they have to the same work. The construction of hypotheses and theories reflects the scientist's interpretation of what he or she has observed even more clearly than observation. At this stage of the scientific method, an element of subjectivity is inevitably present. This can most easily be seen in the extreme case of scientists of truly creative genius. Galileo, for example, challenged the scientists of his day with his hypothesis that the earth revolved around the sun. A twentieth century example is Watson and Crick's discovery of the molecular structure of DNA. Obviously, science may involve not only careful observation but also a willingness to be creative.
