TPO20-1 Westward Migration
Paragraph 1
The story of the westward movement of population in the united states is, in the main, the story of the expansion of American agriculture-of the development of new areas for the raising of livestock and the cultivation of wheat, corn, tobacco, and cotton. After 1815 improved transportation enabled more and more western farmers to escape a self-sufficient way of life and enter a national market economy during periods when commodity prices were high, the rate of westward migration increased spectacularly. “old America seemed to be breaking up and moving westward,” observed an English visitor in 1817, during the first great wave of migration. Emigration to the west reached a peak in the 1830’s. whereas in 1810 only a seventy of the American people lived west of the Appalachian mountains, by 1840 more than a third lived there.
2.What is the purpose of the statement, “whereas in 1810 only a seventy of the American people lived west of Appalachian Mountains, by 1840 more than a third lived there”?
○To illustrate that generally population shifts occur rapidly
○To correct a mistaken impression of American agriculture from 1810 to 1840
○To emphasize the range and speed with which the westward migration occurred
○To demonstrate how attractive the Appalachian Mountains were to Americans
解析：修辞目的题，先读例子所在句子，说向西的移民潮在30年代达到顶峰，接着就给出具体数字来解释，所以是为了说明移民的数量和范围很广，之所以说范围，是因为例子提到阿巴拉契亚山脉以西，所以答案是C。A只说速度，不全面;B没有mistaken view;D说阿巴拉契亚有吸引力纯属扯淡
[1] 美国西进运动的故事大体说来其实就是美国农业扩张的故事，也就是一场开辟用于饲养家畜以及种植小麦、玉米、烟草和棉花的新土地的运动。1815年之后，交通的改善使得越来越多的西部农民摆脱了自给自足的生活方式，进入了国家市场经济。在商品价格较高的那些年，西迁的比率飞速增长。一名英国游客于1817年评价道：“看来旧美国正在瓦解，并移向西部”，当时正值第一次迁移浪潮。西进运动在1830年达到了顶峰。1810年的时候，还仅有七分之一的美国人生活在阿巴拉契亚山的西侧，到1840年的时候这个数字超过了三分之一。
