钢铁是怎样炼成的中的描写珍惜时间的名段

Man’s dearest possession is life.It is given to him but once,and he must live it so as to feel no forturing regrets for wasted years,never know the burning shame of a mean and petty past ; so live that ,dying,he might say all my life,all my strength were given to the finest cause in all the world …… the fight for the liberation of mankind .
人最宝贵的是生命.生命每个人只有一次.人的一生应当这样度过：回忆往事,他不会因为虚度年华而悔恨,也不会因为生活庸俗而羞愧；临死的时候,他能够说：我的整个生命和全部精力,都献给了世界上最壮丽的事业 …… 为解放全人类而斗争.
