张先生离开我们一年了,但他的音容笑貌始终萦绕脑海.和张先生相识,是1996年自己离开校园,到人民教育出版社工作.那时他已经76岁了,从年龄上看,是古稀之年的长者;是儿孙绕膝,颐养天年的时候.但你见到他时,丝毫感受不到他的年龄.他那志在千里的激情和精神,以及为国家数学教育事业做贡献的雄心壮志,耳濡目染,景仰敬意油然而生. Mr. Zhang left us for a year, but his voice is always filled with thoughts. He met Mr. Zhang and left the campus in 1996 to work for the People’s Education Press. At that time, he was 76 years old. From an age point of view, it was The elders of the old century; the children and grandchildren circling their knees to support their days. But when you saw him, you did not feel his age at all. His enthusiasm and spirit for a thousand miles, and for the country’s mathematics education career 3. The ambition for contribution was deafening and admiring.
