     Happiness, Sadness,  Knowledge, Love and all of the other feelings used to live on an island. One

day it was announced that the island would sink, so all built boats and left except Love. Love wanted to

hold out (坚持) until the last possible moment.

     When the island had almost sunk, Love decided to ask for help.

Richness was passing by Love in a grand boat. Love said," Richness, can you take me with you?"

Richness answered, "No, I can't. There is a lot of gold in my boat. There is no place for you here. "

Sadness was close by so Love asked, "Sadness, let me go with you. "  "Oh. . . Love,  I am so sad that I

need to be by myself! "

     Happiness passed by Love too, but she was so happy that she did not even hear when Love called

her.

     Suddenly, there was a voice, "Come, Love, I will take you. " It was an elder.  So overjoyed

(非常高兴), Love even forgot to ask the elder where they were going. When they arrived at a dry land,

the elder went her own way.

     Love asked Knowledge, another elder, "Who helped me?"

     "It was Time," Knowledge answered.

     "Time?" asked Love. "But why did Time help me?"

     Knowledge smiled with deep wisdom and answered, "Because only Time is able to understand how

valuable Love is. "
