单选题The earliest controversies about the relationship between photography and art centered on whether photography's fidelity to appearances and dependence on a machine allowed it to be a fine art, as distinct from merely a practical art. Throughout the nineteenth century, the defense of photography was identical with the struggle to establish it as a fine art. Against the charge that photography was a soulless, mechanical copying of reality, photographers asserted that it was instead a privileged way of seeing, a revolt against commonplace vision, and no less worthy an art than painting. Ironically, now that photography is securely established as a fine art, many photographers find it pretentious or irrelevant to label it as such. Serious photographers variously claim to be finding, recording, impartially observing, witnessing events, exploring themselves--anything but making works of art. In the nineteen century, photography' s association with the real world placed it in an ambivalent relation to art; late in the twentieth century, an ambivalent relation exists because of the Modernist heritage in art. That important photographers are no longer willing to debate whether photography is or is not a fine art, except to proclaim that their own work is not involved with art, shows the extent to which they simply take for granted the concept of art imposed by the triumph of Modernism: the better the art, the more subversive it is of the traditional aims of art. Photographers' disclaimers of any interest in making art tell us more about the harried slaws of the contemporary notion of art than about whether photography is or not art. For example, those photographers who suppose that, by taking pictures, they are getting away from the pretensions of art as exemplified by painting remind us of those Abstract Expressionist painters who imagined they were getting away from the intellectual austerity of classical Modernist painting by concentrating on the physical act of painting. Photography, however, has developed all the anxieties and self-consciousness of a classic Modernist art. Many professionals privately have begun to worry that the promotion of photography as an activity subversive of the traditional pretensions of art has gone so far that the public will forget that photography is a distinctive and exalted activity--in short, an art.

单选题Johnson will phone his mother as soon as he ____ in Kunming.

单选题Children are natural-born scientists, They have 29 minds, and they aren't afraid to admit they don't know something. Most of them, 30 , lose this as they get older. They become self-conscious and don't want to appear stupid. Instead of finding things out for themselves they make 31 that often turn out to be wrong. So it's not a case of getting kids interested in science. You just have to avoid killing the 32 for learning that they were born with. It's no coincidence that kids start deserting science once it becomes formalised. Children naturally have a blurred approach to 33 knowledge. They see learning about science or biology or cooking as all part of the same act—it's all learning. It's only because of the practicalities of education that you have to start breaking down the curriculum into specialist subjects. You need to have specialist teachers who 34 what they know. Thus once they enter school, children begin to define subjects and erect boundaries that needn't otherwise exist. Dividing subjects into science, maths, English, etc, is something that we do for 35 . In the end it's all learning, but many children today 36 themselves from a scientific education. They think science is for scientists, not for them. Of course we need to specialise 37 . Each of us has only so much time on Earth, so we can't study anything. At 5 years old, our field of knowledge and 38 is broad, covering any-thing from learning to walk to learning to count. Gradually it narrows down so that by the time we are 45, it might be one tiny little comer within science.

单选题 The United States has a major problem on its hands. Tree, Britain is facing a similar problem, but for the time being it is in America that it is graver. The only way to solve it is through education. Negroes (黑人) should know about the contributions that black individuals and groups have made towards building America. This is of vital importance for their self-respect: and it is perhaps even more important for white people to know. For if you believe that a man has no history worth mentioning, it is easy to assume that he has no value as a man. Many people believe that, since the Negro’s achievements do not appear in the history books, he did not have any. Most people are taken aback when they learn that Negroes sailed with Columbus, marched with the Spanish conquerors of South America and fought side by side with white Americans in all their wars. People are astonished when you tell them about Phillis Wheatley, who learned English as a salve in Boston and wrote first-class poetry. They have never heard of Benjamin Banneker, a mathematician and a surveyor, who helped to plan the city of Washington. There has been a tendency all along to treat the black man as if he were invisible. Little has been written about the 5, 000 American Negroes who fought in the Revolution against the British, but they were in every important battle. In the Anglo-American War of 1812, at least one out of every six men in the U. S. Navy was a Negro. In the Civil War, more than 200, 000 black troops fought in the Union forces. How, then, did the image of the Negro as a valiant fighting man disappear? To justify the hideous institution of slavery, slave-holders had to create the myth of the docile, slow-witted Negro. incapable of self-improvement, and even contented with his lot. Nothing could be further from the truth. The slave fought for his freedom at every chance he got, and there were numerous uprisings. Yet the myth of docility persisted. There are several other areas where the truth has been twisted or concealed. Most people have heard of the Negro, Carver, who invented scores of new uses for the lowly peanut. But whoever heard of Norbert Rillieux, who in 1846 invented a vacuum pan that revolutionized the sugar-refining industry? Or of Elijah McCoy, who in 1872invented the drip cup that feeds oil to the moving parts of heavy machinery? How many people know that Negroes are credited with inventing such different items as ice creams, potato chips, the gas mask and the first traffic light? Not many. As for the winning of the West, the black cowboy and the black frontiersman have been almost ignored, though film producers are becoming more aware of their importance. Yet in the typical trail crew of eight men that drove cattle from Texas to Kansas, at least two would have been Negroes. The black troops of the Ninth and Tenth Cavalry formed one-fifth of all the mounted troops assigned to protect the frontier after the Civil War. 'What difference does it make?' you may ask. A lot. The cowboy is the American folk-hero. Youngsters identify with him instantly. The average cowboy film is really a kind of morality play, with good guys and bad guys and right finally triumphing over wrong. You should see the amazement and happiness on black youngsters’ faces when they learn that their ancestors really had a part in all that.
