Do you enjoy climbing mountains? I’d like to tell you a true story about John and Peter. They were 66 mountaineers. As John was experienced, he was always asking Peter to copy his example. “Would you like to stand on the 67 of the world, Peter?” “Of course . It has already 68 my dream,”Peter answered.

On a sunny morning, the two men started for the top of Mount Qomolangma. After they climbed over one of the most 69 slopes, they found a man lying in the snow. “He’s going to 70,”Peter looked at John and said, as if he would help the man. “Leave him by himself and just follow me !If you bring the burden with you , I’m 71 you’ll lose your life.”John warned Peter . Then he turned around and walked forward 72. It was too cold. After thinking for a 73 , Peter made up his mind to help the dying man. He carried the man on his back and made his way forward . Little by little , Peter’s temperature made the man74. The man came to himself! And soon he could move all by himself. Together they moved side by side.

About two hours later, they kept up with John.To his surprise , they found that John was almost dead in he snow. He had been 75 to death.
