如果这篇文章写在奥巴马第一次当选美国总统时会有更高的新闻价值和时政价值。不过我还是认为,这篇文章即使是现在也能对不少中国人了解美国社会起到一定的作用。我是读了奥巴马《无畏的希望——重申美国梦》以后才萌生了写这篇文章的念头。该书读后令我收获不少,使我的美国观更加精细和深刻了,也希望读者读后有同样的收获。 If this article is written in Obama’s first election as U.S. president there will be higher news value and current political value. However, I still think that this article can play a role for many Chinese in understanding the American society even now. I read the idea of ​​writing this article after reading “Fearless Hope - Reaffirming the American Dream.” After reading the book I learned a lot, so that my view of the United States more refined and profound, and I hope readers have the same harvest after reading.
