　　Hank Morgan, the hero of Mark Twain’s A Connecticut Yankee in King Arthur’s Court, is a nineteenth-century master mechanic who mysteriously awakening in sixth-century Britain, launches what he hopes will be a peacul revolution to transform Arthurian Britain into an industrialized modern democracy. The novel, written as a spoof (a light humorous parody) of Thomas Malory’s Morte d’ Arthur, a popular collection of fifteenth-century legends about sixth-century Britain, has been made into three upbeat movies and two musical comedies. None of these translations to screen and stage, however, dramatize the anarchy at the conclusion of (at the conclusion of: 当...完结时) A Connecticut Yankee, which ends with the violent overthrow of Morgan’s three-year-old progressive order and his return to the nineteenth century, where he apparently commits suicide after being labeled a lunatic for his incoherent babblings about drawbridges and battlements. The American public, although enjoying Twain’s humor, evidently rejected his cynicism about technological advancement and change through peacul revolution as antithetical to the United States doctrine of progress.

　　17. According to the passage, which of the following is a true statement about the reception of A Connecticut Yankee in King Arthur’s Court by the American public?

　　(A) The public had too strong a beli in the doctrine of progress to accept the cynicism demonstrated at the conclusion of Twain’s novel.

　　(B) Twain’s novel received little public recognition until the work was adapted for motion pictures and plays.

　　(C) Although the public enjoyed Twain’s humor, his use of both sixth-century and nineteenth-century characters confused many people.

　　(D) The public has continued to enjoy Twain’s story, but the last part of the novel seems too violent to American minds.

　　(E) Because of the cynicism at the end of the book, the public rejected Twain’s work in favor of the work of Thomas Malory.

　　18. The author uses the examples of “three upbeat movies and two musical comedies” (lines 9-10) primarily in order to demonstrate that

　　(A) well-written novels like A Connecticut Yankee in King Arthur’s Court, regardless of their tone or theme, can be translated to the stage and screen

　　(B) the American public has traditionally been more interested in watching plays and movies than in reading novels like A Connecticut Yankee in King Arthur’s Court

　　(C) Twain’s overall message in A Connecticut Yankee in King Arthur’s Court is one that had a profound impact on the American public

　　(D) Twain’s A Connecticut Yankee in King Arthur’s Court has been a more popular version of the Arthurian legends than has Malory’s Morte d’ Arthur

　　(E) A Connecticut Yankee in King Arthur’s Court has been accepted as an enjoyable and humorous tale in versions that have omitted the anarchy at the novel’s conclusion

　　19. The author of the passage characterizes Thomas Malory’s Morte d’ Arthur as which of the following?

　　(A) The best-known and most authoritative collection of Arthurian tales written in the English language

　　(B) A collection of legends that have been used as the basis for three movies and two musical comedies

　　(D) A collection of legends about sixth-century Britain that have existed since at least the fifteenth century

　　(E) The novel about the life of King Arthur that inspired Twain’s cynicism about nineteenth-century notions of progress

　　20. It can be inferred from the passage that Mark Twain would most probably have believed in which of the following statements about societal change?

　　(A) Revolutions, in order to be successful in changing society, have to be carried out without violence.

　　(B) Technological advancements are limited in their ability to change society and will likely bring liabilities along with any potential benits.

　　(D) The political system of sixth-century Britain was more conducive to societal change than was the political system of nineteenth-century America.

　　(E) Technological advances and peacul revolutions, although sometimes accompanied by unintended violence and resistance to societal change, eventually lead to a more progressive order.

　　The intensive work of materials scientists and solid-state physicists has given rise to a class of solids known as amorphous metallic alloys, or glassy metals. There is a growing interest among theoretical and applied researchers alike in the structural properties of these materials.

　　When a molten metal or metallic alloy is cooled to a solid, a crystalline structure is formed that depends on the particular alloy composition. In contrast, molten nonmetallic glass-forming materials, when cooled, do not assume a crystalline structure, but instead retain a structure somewhat like that of the liquid—an amorphous structure. At room temperature (room temperature: n.室温, 常温(约20摄氏度)), the natural long-term tendency for both types of materials is to assume the crystalline structure. The difference between the two is in the kinetics or rate of formation of the crystalline structure, which is controlled by factors such as the nature of the chemical bonding and the ease with which atoms move relative to each other. Thus, in metals, the kinetics favors rapid formation of a crystalline structure, whereas in nonmetallic glasses the rate of formation is so slow that almost any cooling rate is sufficient to result in an amorphous structure. For glassy metals to be formed, the molten metal must be cooled extremely rapidly so that crystallization is suppressed.

　　The structure of glassy metals is thought to be similar to that of liquid metals. One of the first attempts to model the structure of a liquid was that by the late J. D. Bernal of the University of London, who packed hard spheres into a rubber vessel in such a way as to obtain the maximum possible density. The resulting dense, random-packed structure was the basis for many attempts to model the structure of glassy metals. Calculations of the density of alloys based on Bernal-type models of the alloys metal component agreed fairly well with the experimentally determined values from measurements on alloys consisting of a noble metal (noble metal: n.贵金属) together with a metalloid, such as alloys of palladium and silicon, or alloys consisting of iron, phosphorus, and carbon, although small discrepancies remained. One difference between real alloys and the hard spheres used in Bernal models is that the components of an alloy have different sizes, so that models based on two sizes of spheres are more appropriate for a binary alloy, for example. The smaller metalloid atoms of the alloy might fit into holes in the dense, random-packed structure of the larger metal atoms.

　　One of the most promising properties of glassy metals is their high strength combined with high malleability. In usual crystalline materials, one finds an inverse relation (inverse relation: 反比关系) between the two properties, whereas for many practical applications simultaneous presence of both properties is desirable. One residual obstacle to practical applications that is likely to be overcome is the fact that glassy metals will crystallize at relatively low temperatures when heated slightly.
