【文章內(nèi)容簡介】 ve score years ago, a great american, in whose symbolic shadow we stand signed the emancipation proclamation. this momentous decree came as a great beacon light of hope to millions of negro slaves who had been seared in the flames of withering injustice. it came as a joyous daybreak to end the long night of captivity.
　　but one hundred years later, we must face the tragic fact that the negro is still not free. one hundred years later, the life of the negro is still sadly crippled by the manacles of segregation and the chains of discrimination. one hundred years later, the negro lives on a lonely island of poverty in the midst of a vast ocean of material prosperity. one hundred years later, the negro is still languishing in the corners of american society and finds himself an exile in his own land. so we have e here today to dramatize an appalling condition.
