A student asked his teacher, "Sir, I have a question. How many friends should a man have, one or many?"
"It is very easy, " the teacher answered. "Get me that red apple from the highest(最高的) branch(树枝) of the tree. " The student looked up and said, "It's too high! I can't get it."
"Ask a friend to help. " the teacher said.
The student called a friend and stood on his shoulders(肩膀) for the branch. "I still can't get it, Sir, " said the student sadly after the first try.
"Don't you have more friends? " the teacher smiled. The student asked more friends to come over. They stood on each other's shoulders, trying to make a pyramid(金字塔) to get higher. But the student still couldn't get the apple. Then one of the friends went home, brought a ladder(梯子) and the student finally got the apple.
After getting the apple, the teacher asked, "So, do you know how many friends a man needs?"
"I do," the student said. "Many, so together we can work out any problem."
"Sounds good, " the teacher said. "You need as many friends as you can. Among( 在······之中) them, there will be at least(至少) one clever man. He can think of a good idea, like getting a ladder!"
