人最宝贵的是生命.生命属于人只有一次.这段话的英文原文?

Man's dearest possession is life.It is given to him but once,and he must live it so as to feel no torturing 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.
汉语对应的译文是：人最宝贵的东西是生命,生命属于我们只有一次,一个人的生命是应该这样度过：当他回首往事的时候,他不因虚度年华而悔恨,也不因碌碌无为而羞耻,这样,在临死的时候,他就可以说：我的整个生命和全部精力都已献给了世界上最壮丽的事业－－－－为人类的解放而斗争.
