过去是一个参照的地方，而不是居住的地方。
The past is a place of reference, not a place of residence.
The sea connects us all; its stewardship requires global unity.
舞台是不可能变为寻常的地方。
The past is never dead. It's not even past.
Your smarts will come in handy because you will travel in a land of marvels. We humans -- plodding as we are -- will astonish ourselves. We'll invent ways to generate clean energy and a lot of it. Atom by atom， we'll assemble tiny machines that will enter cell walls and make repairs. This month comes the extraordinary but also inevitable news that we've synthesized life. In the coming years， we'll not only synthesize it， but we'll engineer it to specifications. I believe you'll even see us understand the human brain. Jules Verne， Mark Twain， Galileo， Newton -- all the curious from the ages would have wanted to be alive most of all right now. As a civilization， we will have so many gifts， just as you as individuals have so many individual gifts as you sit before me.
The ruling ideas of each age have ever been the ideas of its ruling class.
The novel is the most complete and complex expression of human experience.
