Compared to the universe, our lives are really short, just like a meter.But the meaning of life doesn’t depend on its length but contributions.For example, Marie Curie, in order to find the radium, she devoted her whole life to the research.Though the radioactive element had shorter her life, she never gave up her mind to serve the world.According to her story, I conclude that the first meaning of life is contribution.The standard of judging a life isn’t how much he asks for but how much he gives away.

　　和宇宙相比，我们的生命其实很短暂，仿佛只有一米。但是生命的意义并不取决于它的长度，而取决于它的贡献。比如，居里夫人为了发现镭把她的毕生都奉献到研究中。尽管放射性元素缩短了她的生命，但她从来没有放弃为世界服务的决心。根据她的故事，我可以得出这样一个结论，生命的最初意义在于奉献。判断一个人生命的标准不是他索取了多少而是他贡献了多少。
