A young student named Henry came to his teacher and asked him,"Mr.Brown,I have a question.How many friends should a person have
"It is very simple , "Mr.Brown answered."Henry,look!There is a big apple tree over there.Please get me that red apple from the highest branch(树枝)of the tree."
Henry looked up and said,"It's too high!I can't reach it,Mr.Brown."
"Ask a friend.Maybe he can help,"Mr.Brown suggested.
Then Henry called another student and stood on his shoulders(肩膀)to reach the branch.
"I still can't reach it,Mr.Brown,"said Henry sadly after the first try.
"Don't you have more friends?"Mr.Brown smiled.
Henry asked more friends to come over.They stood on each other's shoulders,trying to make a human pyramid(金字塔).But the apple was so high that they couldn't go higher and the pyramid fell.Henry still couldn't reach the apple.Then one of the friends went home(梯子)and Henry finally picked the apple.
After getting the apple,Mr.Brown asked,"So
"I do,"Henry replied."Many,so together we can work out any problem."
"Sounds good,"Mr.Brown said."You need as many friends as you can.Among them,there will be at least one smart person who can think of a good idea
