　　快乐与悲伤

　　Materialistic happiness is short-lived, but happiness achieved by bringing a smile on others face gives a certain level of fulfillment. Peace of mind is the main link to happiness. No mind is happy without peace. We realize the true worth of happiness when we are in sorrow. Sorrow is basically due to death of a loved one, failure and despair.But these things are temporary and pass away。

　　物质上的快乐往往是短暂的，然而，当你给予他人一个微笑的时候，那种满足却是无与伦比的。心灵的平静往往是快乐的源泉。没有平和的心态就没有快乐的心情。 在伤心的时候，我们往往能够体会到快乐的真谛。悲伤基本都来自于一个爱人的去世、失败还有绝望，但是这样的事情都是暂时的，总会过去的。
