关于旅行的英文演讲稿

　　People often wonder why historians go to so much trouble to preserve millions of books, documents and records.

　　Why do we have libraries? What good are these documents and history books? Why do we record and save the actions of men, the negotiations1 of government officials and the events during wars?

　　We do it because, sometimes, the voice of experience can cause us to stop, look and listen. Sometimes, past records, when understood in the right way, can help us decide what to do and what not to do. If we are ever to create lasting peace, we must seek its origins in human experience and in the records of human history.

　　From the stories of courage and devotion of men and women, we create the inspirations of youth. History records the suffering, the self-denial2, the devotion, and the heroic deeds of people in the past. These records can help us when we are confused and when we really need peace.

　　The main purpose of history is to create a better world. History gives a warning to those who promote war, and inspiration to those who seek peace.

　　In short, history helps us learn. Yesterday’s records can keep us from repeating yesterday’s mistakes. And from the pieces of mosaic4 assembled5 by historians come the great murals6 which represent the progress of mankind.
