译文：世俗风气之所以狡诈的人很多，到最后只有忠厚正直的人才能立得住脚；社会风气都以奢侈浮华为上，但最后还是觉得平淡安静的日子才更耐人寻味。赏析：做事就是做人。狡诈的行为虽然可以赢得一时的信任，但最后还是忠厚之人获得永久的尊重。历经人世繁华，方知平淡最真。

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.
