求一篇高中生三分钟左右的演讲词,难度不要太大,题材不限但是要积极

〔另译〕：在八十七年前，我们的国父们在这块土地上创建一个新的国家，乃基于对自由的坚信，并致力于所有男人皆生而平等的信念。〔注：father在此应避免有血缘的联想。在当时的人，尤其是在政治上，没有男女平等的观念，men指的是男人，而且没有说出来的还是白种男人而已。为求忠实，不应将其视为人类的通称。）

Four 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.

当下吾等被卷入一场伟大的内战，以考验是否此国度，或任何肇基于和奉献于斯者，可永垂不朽。吾等现相逢于此战中一处浩大战场。而吾等将奉献此战场之部分，作为这群交付彼者生命让那国度勉能生存的人们最后安息之处。此乃全然妥切且适当而为吾人应行之举。

Now we are engaged in a great civil war, testing 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 this nation might live. It is altogether fitting and proper that we should do this.

但，于更大意义之上，吾等无法致力、无法奉上、无法成就此土之圣。这群勇者，无论生死，曾于斯奋战到底，早已使其神圣，而远超过吾人卑微之力所能增减。这世间不曾丝毫留意，也不长久记得吾等于斯所言，但永不忘怀彼人于此所为。吾等生者，理应当然，献身于此辈鞠躬尽瘁之未完大业。吾等在此责无旁贷献身于眼前之伟大使命：自光荣的亡者之处吾人肩起其终极之奉献—吾等在此答应亡者之死当非徒然—此国度，于神佑之下，当享有自由之新生—民有、民治、民享之政府当免于凋零。

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 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 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 people, shall not perish from the earth.
