     Encouraging words are very important. Here is a story about it.

     A group of frogs were traveling through the woods and two of them fell into a deep hole. When the other

frogs saw how deep the hole was, they told the two frogs that they were as good as dead. The two frogs

ignored (不理睬) the comments and tried to jump out of the hole with all their strength.

    The other frogs kept telling them to stop, that they were as good as dead. Finally, one of the frogs

considered what the other frogs were saying and gave up. He fell down and died. The other frog continued

to jump as hard as he could. Once again, the crowd of frogs shouted at him to stop the pain and just die. He

jumped even harder and finally made it out. When he got out, the other frogs said, "Did you not hear us?"

The frog explained to them that he was deaf. He thought they were encouraging him all the time.

    This story teaches us the following lessons: Be careful of what you say to those who are in trouble. There

is power of life and death in the word. An encouraging word to someone who is down can lift them up and

help them make it through the day.
