The highest mountain in the world is Mount Everest．It is about 8．9 kilometers above sea level．Many men have tried to climb this mountain but without success．High winds, cold and little oxygen have made this almost an impossible thing．It was not until 1953 that two men stood on the top．One of the men was Edmund Hillary from New Zealand．The other was Tenzing of Nepal．They were members of a British Expedition(探險隊)．There were nearly twenty people in the whole team．They spent about sixty days to finish the whole climbing．The last day, May 29^th, was fine．Hillary and Tenzing started climbing as the sun rose． At half past eleven they were on top of Mount Everest．They were very glad．They wanted to stay there for some time, but they couldn’t．It was too cold and dangerous． They had climbed as high as anyone can climb----- they were on top of the world．
