【正确答案】Is there any standard to evaluate the significance of one's life? Certainly, it is quite difficult to bring forward such an absolute standard. However, if we, on the whole, could find out whether his attitude towards his life is serious or not and what is his attitude towards his life and work, it would not be that difficult to make an appropriate evaluation of the meaning of his life.
   From the ancient times till now, all accomplished men treat their lives very seriously. As long as they are alive, they always work and study as hard as possible, unwilling to dream their life away, let alone waste even a single moment of their lives. Such examples have been set a lot by Chinese laboring people, great statesmen and thinkers of past dynasties.
