单选题Is the literary critic like the poet, responding creatively, intuitively, subjectively to the written word as the poet responds to human experience? Or is the critic more like a scientist, following a series of demonstrable, verifiable steps, using an objective method of analysis? For the woman who is a practitioner of feminist literary criticism, the subjectivity versus objectivity, or critic-as-artist-or-scientist, debate has special significance; for her, the question is not only academic, but political as well, and her definition will provoke special risks whichever side of the issue it favors. If she defines feminist criticism as objective and scientific--a valid, verifiable, intellectual method that anyone, whether man or woman, can perform--the definition not only makes the critic-as-artist approach impossible, but may also hinder accomplishment of the utilitarian political objectives of those who seek to change the academic establishment and its thinking, especially about sex roles. If she defines feminist criticism as creative and intuitive, privileged as art, then her work becomes vulnerable to the prejudices of stereotypic ideas about the ways in which women think, and will be dismissed by much of the academic establishment. Because of these prejudices, women who use an intuitive approach in their criticism may find themselves charged with inability to be analytical, to be objective, or to think critically. Whereas men may be free to claim the role of critic-as-artist, women run different professional risks when they choose intuition and private experience as critical method and defense. These questions are political in the sense that the debate over them will inevitably be less an exploration of abstract matters in a spirit of disinterested inquiry than an academic power struggle, in which the careers and professional fortunes of many women scholars only now entering the academic profession in substantial numbers will be at stake, and with them the chances for a distinctive contribution to humanistic understanding, a contribution that might be an important influence against sexism in our society. As long as the academic establishment continues to regard objective analysis as "masculine" and an intuitive approach as "feminine," the theoretician must steer a delicate philosophical course between the two. If she wishes to construct a theory of feminist criticism, she would be well advised to place it within the framework of a general theory of the critical process that is neither purely objective nor purely intuitive. Her theory is then more likely to be compared and contrasted with other theories of criticism with some degree of dispassionate distance.

单选题One of the industrial giants who changed American society was Henry Ford horn on a farm in Michigan in 1863, and he grew up to bring forth some of the most revolutionary improvements in automotive technology in the early 20th century. His outstanding mechanical ability led him to become interested in the new automobiles in the early 1900s. Though be did not invent the automobile, he improved upon everyone else's designs. He was a person who believed in inexpensive, efficient production, so he established standards for his plants and workers. He also standardized and produced many new auto parts for his Ford Motor Company cars. Then he studied the workers' problems and thousands of automobiles per year. In fact, his plants had produced 15 million Model TS by 1927. Ford's personality was not all thrift (节俭), efficiency and inventiveness, however. He was a man who was cold and who could not keep pace with the competition due to his own rigidity (严格). His company suffered because of his desire to maintain the existing state instead of meeting and beating the competition by changing his products. Finally, he saw that he must change or fail, therefore, he introduced a newtype engine and once again took over the automobile market. Ford left a legacy of millions of dollars, millions of jobs for American workers, and millions of satisfied customers.

单选题{{B}}Text 2{{/B}} A variety of significant, attractive short-term benefits will drive the development of modern self-sufficient homes. These include security from severe weather, climate changes, and natural disasters; security from infectious diseases and related health problems; a fresh and nutritious diet; a dependable food supply; and security from global unrest. But the real benefit of Earth Homes will be the long-term sustainability of our planet. It should be no secret that the planet is experiencing unusual weather and climate abnormalities. The 10 hottest years in recorded history have all been in the last 15 years; the 1990s were the hottest decade on record. The Midwestern heat wave of 1995 killed 669 people in Chicago. In 1996, we had a season of record heat spells, and 1997 was the single wan nest year on record--until 1998 shattered global temperature records. Record-high temperatures throughout the southern United States during the summer of 1998 forced the shutdown of Walt Disney World's water parks because of the threat of a viral encephalitis outbreak. The United Nations and insurers blame unusual weather for thousands of deaths and billions of dollars in damage. Many scientists agree that the emissions resulting from human activities are substantially increasing the atmospheric concentration of the greenhouse gases. These increases will enhance the greenhouse effect, resulting in warming of the earth's surface. In 1990, scientists predicted that, if greenhouse gas emissions are not sharply decreased, we might experience a 1C to 3C rise in global temperatures. They suggested that we would have to cut in half our use of coal, oil, and gas in order to lower our emissions enough to maintain concentrations of greenhouse gases at the current levels. Proof of warning includes a decrease in the amount of snow that covers the Northern Hemisphere, a simultaneous decrease in Arctic sea ice, continued melting of alpine glaciers, and a rise in sea level. Rain has even been reported for the first time in Antarctica, and an ice-free patch of ocean about a mile wide has recently opened near the North Pole. Meanwhile, studies have shown that the carbon dioxide concentration in our atmosphere has been steadily increasing since 1958. Even though the rate of emissions from fossil fuels has been reduced, concentration has risen consistently. In 1995, the size of the ozone hole over Antarctica doubled to about the size of Europe. For the first time in recorded history, the hole stretched over populated areas, exposing residents in southern Chile and Argentina to very high levels of ultraviolet (UV) radiation. Studies have shown that a 1% decrease in ozone in the stratosphere produces a 2% increase in UV radiation reaching the ground, posing more risks to humans.
