   Hello, everyone,
   Now I’ll tell you something about our research project The World Food Crisis on behalf of(代表) our group. As you know, food shortages have hit many countries in the world and even caused social unrest in some areas……

Once there was a very brilliant, creative and educated man. He gained much  36  while traveling throughout the world.  37 , he lost his legs and left arm in a tragic accident, leaving only a finger and thumb on his right hand. He became so depressed(沮丧的）that he was afraid he would spend his life 38  and would no longer be able to use his life in a(n)   39  way.
One day, he remembered how he had always loved getting  40  . He realized that he still had partial   41  of his right hand and could write with  42 . Then, he had an idea. “Why not write to other people who need encouragement?”
He  43  where he could find those who could be encouraged if they read his letters. He thought of people in  44 . Many of them had hope of regaining their  45 . Others would keep feeling depressed and remain put away for the rest of their lives. He decided that he must try to  46 them. So he wrote to a prison ministry about sending letters to the prisoners. The prison minister replied that writing to the prisoners would be  47 . However, it would be against prison rules for the prisoners to write back.
 48 with the intention, the man began sending 49 messages of God’s love, hope, strength, and encouragement. He wrote twice a week, testing his strength and ability to the limit. He poured his heart and soul  50 his words,  51  his experience, sense of humor, optimism, and faith.
It was difficult to write those letters, especially without hope of any  52 . Frequently, he felt discouraged, wondering if anyone  53  read his letters. However, this was his  54   chance，so he determined to continue.
At last, he received a letter from the prison officer, which said, “Please write on the best paper you can afford. Your letters are passed from cell (牢房) to cell until they almost fall to   55 !”
We all have unique experiences, abilities and talents. We can discover ways to reach others in need of encouragement and strength.
