听力原文： Once a blind man, being stopped in a bad road, met a lame man, and asked him to help him out of the difficulty into which he had fallen.
"How can I." replied the lame man "since I can hardly drag myself along？ I am lame, and you look to be strong."
"I am strong enough," said the other. "I could go if I could but see the way."
"Oh, then we may help one another," said the lame man. "If you will take me on your shoulders, we will seek our fortunes together. I will be eyes for you, and you shall be feet for me."
"With all my heart." said the blind man. "Let's help each other."
So the blind man took the lame man upon his back, and they traveled on with safety and pleasure.
