Abstract In Seeking Back Your Life Gift, Christopher Moon tends to explore the value of life and the meaning of existence through a vivid and moving story. Peter and Kennedy are close friends and their temper and nature are in accord with each other. Peter is cynical and fights against the world. Kennedy pleases others at full split in order to please himself. Their characters are different, but, they have one thing in common, that is, they are not happy. Until one day, they found the purpose of life from a life-changing adventure and their life totally changed from the adventure.

In this paper, the theme that happiness is the purpose of life will be emphasized in four aspects:

First, the paper will give the definition of gift and indicate that people may feel happy after receiving gifts in order to connect gift with happiness. Secondly, the paper will study the book itself and it will point out that happiness is the purpose of life. Thirdly, it will discuss the reason why both of the two boys in the story are lost and analyze the reason why Peter is lost and why Kennedy is lost. Fourth, and then it will discourse on the way to find out happiness.

In this paper, the reason why Peter and Kennedy are not happy will be found out and the conclusion that happiness is the purpose of life will be reached. There are three ways of finding happiness. Firstly, life itself is valuable, because all of lives are the most special gifts from God. Consequently, everyone can live his own life. Secondly, Happiness is the purpose of one’s Life. Oneself is the first priority and one’s happiness is the most important. Thirdly, happiness calls for compromises with oneself. Better get rid of meaningless striving as long as one has tried his best.
Key Words: the meaning of existence, happiness, ego
摘要 《找回你的生命礼物》中克里斯多夫•孟通过一个生动而感人的故事来与读者探讨一个关于生命价值及生存意义的问题。文中主角彼得和甘乃迪是一对义气相投的好朋友。彼得愤世嫉俗，与世界为敌；甘乃迪拼命取悦别人，以证明自己。他们性格不同，但他们有着相同你的处境——他们都不快乐。直到有一天，一段改变一生的奇遇让他们找到了人生中的快乐，他们的人生从此全然改观。

本文从四部分论述快乐是生命的目的这一主题。第一部分给出礼物的定义并指出人们收到礼物时快乐的心情，进而将礼物与快乐相联系。第二部分通过分析小说指出本文主题——快乐是生命的目的。第三部分议论文中两个男孩不快乐的原因，进而分析他们迷失的原因。第四部分指明找寻快乐的方法。
文中分析彼得与甘乃迪不快乐的原因从而得出快乐是生命的目的的结论后，指出找回快乐的三种方式，即，一、感恩生命：所有的生命都是上天赐予最特别的礼物；二、活出自我：自己是生命的第一优先，论自我快乐的重要性；三、向自己妥协：不成功并不代表不努力，适时向自我妥协才能活得更加快乐。 论《找回你的生命礼物》快乐主题价值:http://www.youerw.com/yingyu/lunwen_35547.html
