　　Although pathogenic organisms constantly alight on the skin, they find it a very unfavorable environment and, in the absence of injury, have great difficulty colonizing it. This “self-sterilizing” capacity of the skin results from the tendency of all well-developed ecosystems toward homeostasis, or the maintenance of the status quo.

　　Species that typically live in soil, water, and elsewhere rarely multiply on the skin. Undamaged skin is also unfavorable to most human pathogens. The skin is too acid and too arid for some species. The constant shedding of the surface skin layers further hinders the establishment of invaders. The most interesting dense mechanism, however, results from the metabolic activities of the resident flora (resident flora: 聚居植物群). Unsaturated fatty acids, an important component of the lipids in sebum collected from the skin surface, inhibit the growth of several bacterial and fungal cutaneous pathogens. These acids are a metabolic product of certain gram-positive members of the cutaneous community, which break down the more complex lipids in freshly secreted sebum.

　　17. The primary purpose of the passage is to

　　(A) offer an analysis of metabolic processes

　　(B) detail the ways in which bacteria and fungi can be inhibited

　　(C) describe mechanisms by which the skin protects itself against pathogens

　　(D) analyze the methods whereby biological systems maintain the status quo

　　(E) provide a specific example of the skin’s basic denses against pathogens

　　18. The “resident flora” mentioned in line 16 rer to

　　(A) “Unsaturated fatty acids” (line 17)

　　(B) “sebum collected from the skin surface” (lines 18-19)

　　(C) “bacterial and fungal cutaneous pathogens” (lines 19-20)

　　(D) “certain gram-positive members of the cutaneous community” (lines 21-22)

　　(E) “more complex lipids” (lines 23)

　　19. Among the natural denses of the skin against pathogenic organisms are all of the following EXCEPT the

　　(A) dryness of the skin

　　(B) acidity of the skin

　　(C) tendency of the pathogens toward homeostasis

　　(D) shedding of surface layers of the skin

　　(E) metabolic breakdown of lipids

　　20. The author presents her material in which of the following ways?

　　(A) Stating a problem and then supplying a solution

　　(B) Presenting a phenomenon and then analyzing reason for it

　　(C) Providing information and then drawing a conclusion from it

　　(D) Making a general statement and then arguing by analogy

　　(E) Making an inference and then developing it by illustration

　　“Masterpieces are dumb,” wrote Flaubert, “They have a tranquil aspect like the very products of nature, like large animals and mountains.” He might have been thinking of War and Peace, that vast, silent work, unfathomable and simple, provoking endless questions through the majesty of its being. Tolstoi’s simplicity is “overpowering (overpowering: adj.无法抵抗的, 压倒性的),” says the critic Bayley, “disconcerting,” because it comes from “his casual assumption that the world is as he sees it.” Like other nineteenth-century Russian writers he is “impressive” because he “means what he says,” but he stands apart from all others and from most Western writers in his identity with life, which is so complete as to make us forget he is an artist. He is the center of his work, but his egocentricity is of a special kind. Goethe, for example, says Bayley, “cared for nothing but himself. Tolstoi was nothing but himself.”

　　For all his varied modes of writing and the multiplicity of characters in his fiction, Tolstoi and his work are of a piece (of a piece: adj.一致的). The famous “conversion” of his middle years, movingly recounted in his Confession, was a culmination of his early spiritual life, not a departure from it. The apparently fundamental changes that led from epic narrative to dogmatic parable, from a joyous, buoyant attitude toward life to pessimism and cynicism, from War and Peace to The Kreutzer Sonata, came from the same restless, impressionable depths of an independent spirit yearning to get at the truth of its experience. “Truth is my hero,” wrote Tolstoi in his youth, reporting the fighting in Sebastopol. Truth remained his hero—his own, not others’, truth. Others were awed by Napoleon, believed that a single man could change the destinies of nations, adhered to meaningless rituals, formed their tastes on established canons of art. Tolstoi reversed all preconceptions; and in every reversal he overthrew the “system,” the “machine,” the externally ordained beli, the conventional behavior in favor of unsystematic, impulsive life, of inward motivation and the solutions of independent thought.

　　In his work the artificial and the genuine are always exhibited in dramatic opposition: the supposedly great Napoleon and the truly great, unregarded (unregarded: adj.不受注意的) little Captain Tushin, or Nicholas Rostov’s actual experience in battle and his later account of it. The simple is always pitted against (be pitted against: 被置于与…的对抗中) the elaborate, knowledge gained from observation against assertions of borrowed faiths. Tolstoi’s magical simplicity is a product of these tensions; his work is a record of the questions he put to himself and of the answers he found in his search. The greatest characters of his fiction exemplify this search, and their happiness depends on the measure of their answers. Tolstoi wanted happiness, but only hard-won happiness, that emotional fulfillment and intellectual clarity which could come only as the prize of all-consuming fort. He scorned lesser satisfactions.

　　21. Which of the following best characterizes the author’s attitude toward Tolstoi?

　　(C) Important works of art take their place in the pageant of history because of their uniqueness.

　　(D) The most important aspects of good art are the orderliness and tranquility it rlects.

　　(E) Masterpieces which are of enduring value represent the forces of nature.

　　23. The author quotes from Bayley (line 8-20) to show that

　　(A) although Tolstoi observes and interprets life, he maintains no self-conscious distance from his experience

　　(B) the realism of Tolstoi’s work gives the illusion that his novels are reports of actual events

　　(C) unfortunately, Tolstoi is unaware of his own limitation, though he is sincere in his attempt to describe experience

　　(D) although Tolstoi works casually and makes unwarranted assumption, his work has an inexplicable appearance of truth
