　　B

　　Once upon a time, on his way to the Himalayas, was a saint(圣徒). He came across a shallow river he had to cross. Just when he was about to wet his feet, he saw a scorpion(蝎子)helplessly trying to come out of the river. It was almost touching the bank but not enough to gain hold of the ground. The saint saw scorpion’s struggle and decided to save it.

　　He picked up the scorpion in his right hand with the intention to place it on the dry surface. No sooner did he do that than the scorpion stung and rushed off the hand, landing in the water again. It struggled to come out of water again. The saint’s body was in pain but his mind, calm.

　　Seeing that the scorpion could lose its life, the saint used left hand this time to lift the scorpion out of water. However, it panicked and stung again. Once again, it sped off the hand and fell in water. He was left with both hands filled with pain. He was not the one to give up either.

　　He tried again. This time, he cupped his hands together and lifted the scorpion in one swift movement. Before it could react, he safely dropped it on the land. The scorpion disappeared into the pebbles that lay near the bank. He felt happy, for he succeeded in carrying out his rescue, for saving another life. It was worth the pain he thought.
