7)The American Civil War and its impaction on the development of the U.S 美国内战

①The conflict between the North and the South: In the early 1800’s, black slavery disappeared in the north because of industry development. But it continued to exist in the South. In the South, farming remained the most important way of making a living and the planter farmed a large area of land. Slave labors seemed best suited for producing these crops.19世纪早期，由于工业的发展，黑奴在北方消失。但在南方仍然存在。在南方，农耕是最主要的谋生手段，农场主耕种了大片土地。奴隶劳动力似乎最适于这些农作物的生产。

Many black slaves joined the Union Army. 亚伯拉罕. 林肯:当林肯成为美国总统后，1861.4.12爆发战争，他意识到可以把战争变为反奴隶的正义战争，从而获得国内外对联邦的支持。所以他颁布了著名的《解放宣言》。这样英法各国站到了联邦一边，许多黑奴加入了联邦军。

Lincoln’s speech: That government of the people, by the people, for the people, shall not perish from the earth.民有，民治，民享的政府是不会从地球上消亡的。The Thirteenth Amendment, which banned slavery, was added to the Constitution in December,1865.废除奴隶制的第十三修正案于1865年12月写入宪法。
