Practice 3　　中华文明历来注重自强不息，不断革故鼎新。“天行健，君子以自强不息。”这是中国的一句千年传世格言。中华民族所以能在5000多年的历史进程中生生不息、发展壮大，历经挫折而不屈，屡遭坎坷而不馁，靠的就是这样一种发愤图强、坚忍不拔、与时俱进的精神。　　中国人民在改革开放中表现出来的进取精神，在建设国家中焕发出来的创造热情，在克服前进道路上的各种困难中表现出来的顽强毅力，正是这种中国传统文化中自强不息精神的生动写照。

As an ancient Chinese motto puts it, “As Heaven keeps vigor through movement, a gentleman should unremittingly practice self-improvement.” Throughout its 5,000-year history, it is thanks to their perseverance, determination, stamina and innovation that the Chinese nation has grown after surviving numerous setbacks and adversity. The Chinese people have shown enterprising spirit and reform and opening-up creativity in national development and great tenacity in overcoming difficulties on the road to progress. And all this gives expression to the spirit of unremitting self-improvement embodied in China’s cultural tradition.
