奧巴馬將親臨紀念民權大遊行50週年儀式
U.S. President Barack Obama will give the keynote address at Wednesday's observance of the 50th anniversary of the March on Washington, the historic 1963 demonstration for equal rights that drew more than 250,000 people to the Lincoln Memorial.
Mr. Obama, the nation's first black president, will deliver his remarks to tens of thousands of people who are expected to attend the commemoration.
Also appearing at Wednesday's anniversary observance will be former presidents Jimmy Carter and Bill Clinton, and media personality Oprah Winfrey.
The march 50 years ago was capped by the Reverend Martin Luther King, Junior's famous "I Have a Dream" speech for racial harmony and justice, hailed by historians as one of the greatest ever delivered.
The 1963 "March on Washington for Jobs and Freedom" was held at the height of the American civil-rights movement that was aimed at ensuring the rights of all people are equally protected by the law. The movement had faced strong and sometimes violent resistance to ending the practice of segregation that treated white and black Americans differently under the law.美國總統奧巴馬將在星期三(8月28日)華盛頓民權大遊行50週年紀念日發表主題演說。1963年舉行的那次歷史性示威要求平等權利，吸引了25萬人聚集在林肯紀念堂。
奧巴馬是美國曆史上第一位黑人總統，他將對參加紀念儀式的數以萬計的人發表演說。
50年前的歷史性事件以黑人牧師馬丁•路德•金“我有一個夢”的著名演說達到高潮，他的演說以種族和諧和公正爲主旨，被歷史學家稱之爲最偉大的演講之一。
傳媒界名人奧普拉•溫弗雷、前總統吉米•卡特和比爾•克林頓也將出席星期三的紀念儀式。
1963年“進軍華盛頓爭取就業與自由”大遊行發生在美國民權運動的高潮期。這場運動要求確保所有人的權利都能得到法律的平等保護。民權運動號召廢除種族隔離制度。把黑人和白人分隔的做法符合當時的法律，民權運動的這項訴求遭到社會上很多人的強烈有時甚至是暴力的抵制。
