Long ago, in a far-away place, an old tribal chief found himself terminally ill.  So he called three most promising young villagers to his bedside and said, “As I    (leave)you soon, I hope you can do one more thing for me. Young men, you three are all    (usual)strong and resourceful, so I’d like you to strive to climb that high mountain we have always been worshipping    a sacred place. Try to reach the top and then turn back to tell me about your findings.
Three days later, the first young man returned smartly dressed and said     (smile), “Lord, I’ve been to the mountaintop     I saw flowers of all sorts, spring water and singing birds.  That’s a real nice place. ”
The old tribal chief replied with a smile, “Son, I’ve been there before. It’s not the mountaintop     the foot of the mountain. You can leave now. ”
A week later, the second young man also returned. “Lord, I’ve been to the mountaintop    a forest of tall pine trees and vultures circling in the air. That’s a really nice place. ”
“What a pity! ”said the chief. “Son, you’ve been halfway up the mountain rather than to the summit. Now you can leave. ”
A month later, the third young man showed up in rags, his hair off-colored but his eyes clear and bright.
“Lord, I succeeded in reaching the summit. There was nothing there but the highland wind and the blue sky     (hang)over the land. ”
“So you saw nothing at all? Not even    butterfly? ”
“No, Lord, nothing. All you can see is yourself. You just feel how insignificant you are in this infinite universe     standing at the top! ”
“Son, you’ve reached the real mountaintop. Congratulations! You will be undoubtedly made our new tribal chief! ”
