Needless to say, nothing but perseverance can lead a man to the way of success. In other words, a persevering man　never does his work without succeeding in it. This is indeed unchangeable truth.

　　Our National Father, Dr. Sun Yat-Sen, is the most ideal example. He was devoted to the revolution about forty years.

　　He met with many failures, but he was anything but discouraged.As a result, he won. The Republic of China was born.

　　不需说，只有毅力才能引导人迈向成功之途。换句话说，一个具有毅力的人做工作终是(never...without)会把它做成功的。这真是不易之定理也。

　　我们国父孙中山先生是一个最理想的例了.致力国民革命凡四十年。他遭遇到许多次的失败，但是他决不灰心。结果，他赢了。中华民国诞生了。
