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。

篇二：是否应该以他人生命为代价来拯救另一生命

　　In recent years, the news about saving others' lives at the cost of one's own are frequently reported. Some people praise the people who save others, becuase it's traditional virtue in China to help those who are in need. However, some other people argue that it's not worth to save others lives at the cost of one's own and it should not be encouraged. As far as I am concerned, the spirit of self-sacrifice is worthy for us to learn, but we should find amore appropriate way to avoid accident as well.

　　近年来，关于用自己的生命为代价来拯救别人的生命的新闻频繁被报道。有的人赞扬拯救别人的人，因为帮助需要的人是中国的传统美德。然而，其他人争论到，以自己的生命为代价去拯救别人的生命是不值得的，这种行为不应该太被鼓励。在我看来，自我牺牲精神是值得我们学习的，但是我们也应该找一个更合适的方法来避免事故。
