TEXT:History has earned some inspiring look at how self-determination and innovation made America.
Now,a special introduction from the President of United State.
Good evening.

Over two hundred years ago,the world waited and watched to see if an unlikely experiment called America would succeed.It has,Not because the success was certain,or because it was easy，but because generations of Americans delicated their lives and the sacred honor to a cause greater than themselves.

This has been especially true in moments of trial.when a ragtag group of patriots overthrew an empire to secure the right to life,liberty and the pursuit of happiness.when an lllinois rail splitter proved for all time that a government of,by and for the people would endure.when marcher's brave beatings on the Alabama bridge in the name of equality,freedom and justice for all.Moments like these remind us that our American stories have never been inevitable.those made possible by ordinary people who kept moral compass pointed straight and true.when the way seemed treacherous,when the climb seemed step,when the future seemed uncertain.people who were recognized as the fundamental part of our American characters.We can remake ourselves,and our nation to fit our larger dreams.

Tonight,thorough the series,I hope you'd be inspired by these extraordinary men and women and think about how this generation will write the next chapter in our great American story.

Thank you and enjoy the show.
