　　托福阅读句子插入题：Early Settlements in the Southwest Asia

　　The universal global warming at the end of the Ice Age had dramatic effects on temperate regions of Asia, Europe,　and North America. Ice sheets retreated and sea levels rose. ■The climatic changes in southwestern Asia were more　subtle, in that they involved shifts in mountain snow lines, rainfall patterns, and vegetation cover. ■However, these same　cycles of change had momentous impacts on the sparse human populations of the region. ■At the end of the Ice Age, no　more than a few thousand foragers lived along the eastern Mediterranean coast, in the Jordan and Euphrates valleys.

　　Within 2,000 years, the human population of the region numbered in the tens of thousands, all as a result of village life　and farming. ■Thanks to new environmental and archaeological discoveries, we now know something about this　remarkable change in local life.(Early Settlements in the Southwest Asia)
