3、意。 到了葬禮的前一天晚上，還在做最后的修改，然后半夜找到他的同僚高聲朗 誦。走進(jìn)會(huì)場(chǎng)時(shí)， 他騎在馬上仍把頭低到胸前默想著演說(shuō)辭。那位艾佛瑞特講演了兩個(gè)多小時(shí)，將近結(jié)束時(shí)，林肯不安地掏出舊式眼鏡，又一次看他的 講稿。他的演說(shuō)開(kāi)始了，一位記者支上三角架準(zhǔn)備拍攝照片，等一切就緒的 時(shí)候，林肯已走下 講臺(tái)。這段時(shí)間只有兩分鐘，而掌聲卻持續(xù)了 10分鐘。后人給以極高評(píng)價(jià)的那份演說(shuō)辭，在今 天譯成中文，也不過(guò)400字。林肯的這篇演說(shuō)是演說(shuō)史上著名的篇章，其思想的深刻，行文的嚴(yán)謹(jǐn)，語(yǔ)言的冼練，確實(shí) 是不愧彪炳青史的大手筆。GETTYSBURG ADDRESS Abraham Lincoln Deliver

4、ed on the 19th Day of November, 1863 Cemetery Hill,Gettysburg, PennsylvaniaFour score and seven years ago our fathers brought forth on this continent, a new nation, conceived in Liberty, and dedicated to the proposition that all men are created equal.Now we are engaged in a great civil war, testing

5、whether that nation, or any nation so conceived and so dedicated, can long endure. We are met on a great battle-field of that war. We have come to dedicate a portion of that field, as a final resting place for those who here gave their lives that that nation might live. It is altogether fitting and

6、proper that we should do this.But, in a larger sense, we can not dedicate - we can not consecrate - we can not hallow - this ground. The brave men, living and dead, who struggled here, have consecrated it, far above our poor power to add or detract. The world will little note, nor long remember what

7、 we say here, but it can never forget what they did here. It is for us the living, rather, to be dedicated here to the unfinished work which they who fought here have thus far so nobly advanced. It is rather for us to be here dedicated to the great task remaining before us - that from these honored

8、dead we take increased devotion to that cause for which they gave the last full measure of devotion - that we here highly resolve that these dead shall not have died in vain - that this nation, under God, shall have a new birth of freedom - and that government of the people, by the people, for the p
