TPO24-3 Moving into Pueblos迁入普韦布洛
普韦布洛(Pueblo)是美国科罗拉多州一座自治城市，位于该州中南部阿肯色河畔。看过机经的同学可能会注意，到今年的9月29日就又考过Pueblo相关的内容。本篇文章题目设置都比较直接，好定位，文章逻辑结构也较清晰，分两大方面，不同小点解释人们集群而居的原因。但究其细节及背景知识，我们还是应该花些时间对本文进行细致分析的。
1. In the Mesa Verde area of the ancient North American Southwest, living patterns changed in the thirteenth century, with large numbers of people moving into large communal dwellings called pueblos, often constructed at the edges of canyons, especially on the sides of cliffs.(分清各种修饰成分在本句的修饰主体及起到的功能。)
2. Few of the cultural traditions and rules thattoday allow us to deal with dense populations existed for these people accustomed to household autonomy and the ability to movearound the landscape almost at will. (推理题出处：反向推理，说之后，问之前。)
3. Population growth is considered a particularlyinfluential push. After several generations of population growth, people packed the landscape in densities so high that communal pueblos may have been anecessary outcome. (因果关系：事实信息题出处。)

6. Archaeologists find that even the most isolated residences during the eleventh and twelfth centuries obtained some pottery, and probably food, from some distance away, while major ceremonial events were opportunities for sharing food and crafts.(事实信息题出处：目的。)
7. Scholars believe that this cooperation allowed people to contend with a patchy environment in which precipitation and other resources varied across the landscape: if you produce a lot of food one year, you might trade it for pottery made by a distant ally who is having difficulty with crops—and the next year, the flow of goods might go in the opposite direction. But all of this appears to have changed thirteenth century.Although the climate remained as unpredictable as ever between one year and the next, it became much less locally diverse.(前后变化：事实信息题考点。)
