人最宝贵的是生命。生命对人只有一次。人的一生应当这样度过:当回忆往事的时候,他不会因为虚度年华而悔恨,也不会因为碌碌无为而羞愧;在临死的时候,他能够说:“我的整个生命和全部精力,都已经献给了世界上最壮丽的事业——为人类的解放而斗争。”“前苏联”奥斯特洛夫斯基 The most precious thing for people is life. Life is only once for people. A person’s life should be spent like this: When he recalls past events, he will not be remorseless because of his age, nor will he be ashamed of being incapable of doing nothing; when he is dying, he can say: “My entire life and all my energy , have been dedicated to the world’s most magnificent cause - the struggle for the liberation of mankind.“ ”The former Soviet Union" Ostrovsky
