TPO8-1The Rise of Teotihuacán 特奥蒂瓦坎的崛起
1. Amongthe main factors are Teotihuacán’s geographic location on a natural trade routeto the south and east of the Valley of Mexico, the obsidian resources in theTeotihuacán Valley itself, and the valley’s potential for extensive irrigation.The exact role of other factors is much more difficult to pinpoint―for instance, Teotihuacán’s religious significance as a shrine, the historical situation in and around the Valley of Mexico toward the end of the first millennium B.C., the ingenuity and foresightedness of Teotihuacán’s elite, and,finally, the impact of natural disasters, such as the volcanic eruptions of thelate first millennium B.C.(列举句，信息点碎但不乱，排除题出处。)
2. Aroundthis time, the largest of these centers, Cuicuilco, was seriously affected by a volcanic eruption, with much of its agricultural land covered by lava. With Cuicuilco eliminated as a potential rival, any one of a number of relatively modest towns might have emerged as a leading economic and political power in Central Mexico. (两个with介词短语，都暗示原因，推断题出处。)
3. Itseems likely that Teotihuacán’s natural resources, along with the city elite’s ability to recognize their potential, gave the city a competitive edge over its neighbors.(细节题出处。读懂句子，绝不是单纯的每个词都认识就够了，更要读懂其深意，识别其同意改写。)
4. Long-distan cetrade in obsidian probably gave the elite residents of Teotihuacán access to a wide variety of exotic good, as well as a relatively prosperous life. ……It is also probable that as early as 200B.C. Teotihuacán may have achieved some religious significance and its shrine (or shrines) may have served as anadditionalpopulation magnet.(双选细节题出处，注意其“文绉绉”的表达方式。)
5. Thepicture of Teotihuacán that emerges is a classic picture of positive feedback among obsidian mining and working, trade, population growth, irrigation, and religious tourism.(观点句，修辞目的题出处。)
6. The growing power of the elite, who controlled the economy, would give them the means to physically coerce people to move to Teotihuacán and serve as additionsto the labor force.
