TPO20-2 EARLY SETTLEMENTS IN SOUTHWEST ASIA
Paragraph 2
Pollen samples from freshwater lakes in Sria and elsewhere tell us forest cover expanded rapidly at the end of the Ice Age, for the southwestern Asian climate was still cooler and considerably wetter than today. Many areas were richer in animal and plant species than they are now, making them highly favorable for human occupation. About 9000 B.C., most human settlements lay in the area along the Mediterranean coast and in the Zagros Mountains of Iran and their foothills. Some local areas, like the Jordan River valley, the middle Euphrates valley, and some Zagros valleys, were more densely populated than elsewhere. Here more sedentary and more complex societies flourished. These people exploited the landscape intensively, foraging on hill slopes for wild cereal grasses and nuts, while hunting gazelle and other game on grassy lowlands and in river valleys. Their settlements contain exotic objects such as seashells, stone bowls, and artifacts made of obsidian (volcanic glass), all traded from afar. This considerable volume of intercommunity exchange brought a degree of social complexity in its wake. 5 Why does the author mention “seashells, stone bowls, and artifacts made of obsidian”?
○to give examples of objects obtained through trade with other societies.
○to illustrate the kinds of objects that are preserved in a cool climate
○to provide evidence that the organization of work was specialized
○to give examples of the artistic ability of local populations.
解析：修辞目的题，先看例子所在句子，说定居点里包含很多通过贸易获得的外来物品，诸如blabla，所以这些东西都是外来品，A是正确答案。B/C/D都没说。
[2] 来自叙利亚和其他地方的淡水湖的花粉样本向我们揭示出在冰河时代末期森林覆盖迅速增长，这是因为当时亚洲西南部的气候比现在要更凉爽，而且要湿润得多。当时很多地区的动植物种类要比现在丰富，这就使得这些地区非常适宜人类居住。大约在公元前9ooo年，大部分人类定居点都位于地中海沿岸以及伊朗的扎格罗斯山脉和丘陵地带。某些局部地区，例如约旦河谷、幼发拉底河谷中部以及某些扎格罗斯谷地的人口就比别的地方要更密集。迁移性更低、更为复杂的社会在这里兴旺发展起来。这些人对该地貌进行高强度的开发，他们在山坡上采集野生的谷物和坚果，在长满青草的低地和河谷中捕捉瞪羚及其他猎物。在他们的定居点发现了从远方交易获得的外来物品，例如贝壳、石碗和黑曜石(火山玻璃)制成的古器。这种数量可观的社会间的交换随后给社会带来了一定的复杂度。
