单选题26. The great majority of extant decorated artifacts from the Middle Period of the Byzantine Empire are objects that were designed for ecclesiastical use. But even those decorated artifacts with no apparent ecclesiastical function are almost all decorated with religious scenes and symbols.

单选题. ①The space between the stars is filled with matter that interstellar conditions should prevent from coalescing into solid particle. ②Yet surprisingly tiny frozen particles, referred to as interstellar grains, do develop in these spaces. ③These grains are formed out of chemical elements that are synthesized during thermonuclear fusion in stars and supernova explosions. ①The study of interstellar grains has been hampered by the inaccessibility of naturally occurring specimens for use in laboratory experiments. ②To date, the only source of information about interstellar grains is the stellar electromagnetic radiation that reaches the Earth after passing through regions of space containing interstellar grains. ③By observing the wavelengths scattered and absorbed by the grains scientists have determined that a grain's internal structure consists of a core composed of silicates (rocklike material) and a mantle composed entirely of organic compounds. ④It is hypothesized that each grain begins as a silicate "seedling" ejected from a mature star. ⑤Continuous physical and chemical evolution then occurs in the mantle formed around the seedling.40. The author uses the term "seedling" most probably in order to ______

单选题. ①Abolitionist Frederick Douglass' move to Rochester, New York, in 1847 was a major step in his finding his own intellectual path. ②Along with much of the rest of western New York, Rochester became fertile ground for an antislavery movement that dissented from that led by William Lloyd Garrison, with whom Douglass had previously been aligned. ③Unlike the Garrisonians, who believed the Union established by the United States Constitution must be dissolved in order to abolish slavery, many Rochester activists began to see both the Constitution and the political process as invaluable instruments for achieving that goal. ④During the 1840s and 1850s, many abolitionists had become frustrated by the failure of Garrison's method of moral persuasion. ⑤They turned instead to politics to fight slavery.19. Which of the following statements best describes the function of the highlighted sentence? ______

单选题19. A plant-based automobile fuel has just become available in Ternland. A car can be driven as far on a gallon of the new plant-based fuel as a car can be driven on a gallon of gasoline, but a gallon of the plant-based fuel both costs less and results in less pollution. Therefore, drivers in Ternland who switch to it will reduce the amount they spend on fuel in a year while causing less environmental damage. Which of the following is an assumption on which the argument relies? ______

单选题. ①The male lion's mane consists of hair of varying length and color, covering, to varying degrees, the head, neck, shoulders, and chest. ②Schaller suggested that the mane protects the area of the body "towards which most social contact is directed" by absorbing blows and bites. ③Darker mane hairs are thicker than lighter hairs, so darker manes may provide better protection. ④These ideas suggest that males with longer and darker manes will be wounded less frequently and/or with less severity on the area covered by the mane, but direct tests of this prediction are difficult. ⑤Individual males are seldom seen daily, and the mane itself obscures many wounds beneath it from view. ⑥Furthermore, even in the best studied population, serious fights between lions are rarely observed.1. Which of the following best describe the function of the highlighted portion of the passage? ______

单选题. ①Carolina Hospital notes that Cuban-American writers who write primarily in English are dismissed from anthologies and analyses of Cuban exile literature on that account. ②She argues that since these writers were born in Cuba and consider themselves Cuban writers, they should not be ignored, and maintains that they represent a new phase of Cubanness, one that is expressed in the language comfortable to its writers: English. ③Moreover, another critic notes that the Spanish and English traditions of Cuban-American writing have different but equally viable functions. ④The English branch seeks to create a distinctive culture of Cuban roots in the United States, whereas the Spanish branch wishes to preserve a specifically Cuban culture while seeking affiliation with the canon of Latin American letters.20. Hospital, as presented in the passage, would probably agree with which of the following statements about Cuban-American writing? ______
