Compared to the universe, our lives are really short, just like a meteer.

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。

The second meaning of life is struggling for our goals. Each of us has goals, such as longing for position, hoping for wealth and looking forward to be loved. However, the path leading to them isn’t filled with roses. But no matter how tough to accomplish our dream we should never say die. If  you really want to achieve them, please keep diligent and patient just like an English motto goes;“No pains ,no gains.”

生命的第二大意义在于为我们的目标努力奋斗。我们每个人都有目标，比如追求职位，渴望财富，期待被爱。但是，通往它们的道路是布满荆棘的。但是不管实现梦想有多艰难，我们都应该永不言败。如果你真的想实现它们，请保持勤奋和耐心，就像一句英语座右铭说的：“没有付出就没有收获。”

The third meaning of life is happiness. Not only should we keep happy, but also bring enjoyment to others .For example, we can have an optimistic attitude which can affect the people in our surroundings. Besides, we are supposed to be ready to help others, because in this way we can make both us and them happy .I consider it an unchangeable truth that ‘Helping others creates happiness.’

生命的第三大意义在于快乐。我们不仅应该保持快乐，也应该给别人带来快乐。比如，我们可以抱着乐观的态度去影响身边的人。此外，我们应该乐于助人，因为这样我们可以使我们和别人都开心。我认为“助人为乐”是不变的真理。

 just want to say, the lives for us are limited, but we are able to make efforts to make it shine out .Believe it, though our lives are rather short, we can also make a hit .If we try our best, our lives will be meaningful as well.

我只想说，生命给予我们的是有限的，但是我们可以努力使它发光。相信，尽管我们的生命很短暂，我们同样可以使它绽放光芒。如果我们尽力了，我们的生命同样有意义。
