I say to you, my friends, so even though we must face the difficulties of today and tomorrow, I still have a dream. It is a dream deeply rooted in the American dream. I have a dream that one day this nation will rise up and live out the true meaning of its creed - we hold these truths to be self-evident, that all men are created equal. I have a dream that one day on the red hills of Georgia, sons of former slaves and sons of former slave-owners will be able to sit down together at the table of brotherhood. I have a dream that one day, even the state of Mississippi, a state sweltering with the heat of injustice, sweltering with the heat of oppression, will be transformed into an oasis of freedom and justice. I have a dream my four little children will one day live in a nation where they will not be judged by the color of their skin but by the content of their character. I have a dream today! I have a dream that one day down in Alabama, with its vicious racists, with its governor having his lips dripping with the words of interposition and nullification, one day right there in Alabama little black boys and black girls will be able to join hands with little white boys and white girls as sisters and brothers; I have a dream today. I have a dream that one day every valley shall be exalted, every hill and mountain shall be made low, the rough places shall be made plain, and the crooked places shall be made straight and the glory of the Lord will be revealed and all flesh shall see it together. This is our hope. This is the faith that I go back to the South with. With this faith we will be able to hew out of the mountain of despair a stone of hope. With this faith we will be able to transform the jangling discords of our nation into a beautiful symphony of brotherhood. With this faith we will be able to work together, to pray together, to go to jail together, knowing that we will be free one day. 答案补充 This will be the day when all of God's children will be able to sing with new meaning-＂my country 'tis of thee; sweet land of liberty; of thee I sing; land where my fathers died, land of the pilgrim's pride; from every mountain side, let freedom ring＂-and if America is to be a great nation, this must become true. So let freedom ring -- from the prodigious hill tops of New Hampshire, let freedom ring; from the mighty mountains of New York.Let freedom ring -- from the 答案补充 heightening Alleghenies of Pennsylvania. Let freedom ring from the snow-capped Rockies of Colorado. Let freedom ring from the curvaceous slopes of California. But not only that.Let freedom ring from the Stone Mountain of Georgia. Let freedom ring from Lookout Mountain of Tennessee. Let freedom ring from every hill and molehill of Mississippi, from every mountainside, let freedom ring. 答案补充 When we allow freedom to ring, when we let it ring from every village and hamlet, from every state and city, we will be able to speed up that day when all of God's children - black men and white men, Jews and Gentiles, Catholics and Protestants - will be able to join hands and to sing in the words of the old Negro spiritual, ＂Free at last, free at last; thank God Almighty, we are free at last.＂
