文章:Theorists are divided concerning the origin of the Moon. Some hypothesize that the Moon was formed in the same way as were the planets in the inner solar system (Mercury, Venus, Mars, and Earth)—from planet-forming materials in the presolar nebula. But, unlike the cores of the inner planets, the Moon‘s core contains little or no iron, while the typical planet-forming materials were quite rich in iron. Other theorists propose that the Moon was ripped out of the Earth‘s rocky mantle by the Earth‘s collision with another large celestial body after much of the Earth‘s iron fell to its core. One problem with the collision hypothesis is the question of how a satellite formed in this way could have settled into the nearly circular orbit that the Moon has today. Fortunately, the collision hypothesis is testable. If it is true, the mantle rocks of the Moon and the Earth should be the same geochemically. 问题:3. Which of the following, if true, would be most likely to make it difficult to verify the collision hypothesis in the manner suggested by the author? (A) The Moon‘s core and mantle rock are almost inactive geologically. (B) The mantle rock of the Earth has changed in composition since the formation of the Moon, while the mantle rock of the Moon has remained chemically inert. (C) Much of the Earth‘s iron fell to the Earth‘s core long before the formation of the Moon, after which the Earth‘s mantle rock remained unchanged. (D) Certain of the Earth‘s elements, such as platinum, gold, and iridium, followed iron to the Earth‘s core. (E) The mantle rock of the Moon contains elements such as platinum, gold, and iridium. 我选的是B,答案是D
定位段:According to Webb, the purpose of garrison government was to provide military support for a royal policy designed to limit the power of the upper classes in the American colonies. Webb argues that the colonial legislative assemblies represented the interests not of the common people but of the colonial upper classes, a coalition of merchants and nobility who favored self-rule and sought to elevate legislative authority at the expense of the executive. It was, according to Webb, the colonial governors who favored the small farmer, opposed the plantation system, and tried through taxation to break up large holdings of land. Backed by the military presence of the garrison, these governors tried to prevent the gentry and merchants, allied in the colonial assemblies, from transforming colonial America into a capitalistic oligarchy.
问题 7. According to Webb‘s view of colonial history, which of the following was (were) true of the merchants and nobility mentioned in the second paragraph? A They were opposed to policies formulated by Charles II that would have transformed the colonies into capitalistic oligarchies. B They were opposed to attempts by the English crown to limit the power of the legislative assemblies. C They were united with small farmers in their opposition to the stationing of English troops in the colonies. 我选的是C 答案是B,我觉得出题点应该就是加粗这句了吧,选项B的意思怎么感觉是和这句相反的呢?求各位指教 |
