Jane Hugesová ze základního tábora na Mount Everestu : Sibusiso Vilane spoke to the BBC by radio from the summit of Everest and said he was crying tears of joy. He said he was feeling well and was very grateful to be there. He's spent weeks at base camp and up on the mountain acclimatising and waiting for a break in the weather. He reached the top of the world after climbing through a clear and starlit night. But the winds are now much stronger and he still has to get safely back down the mountain - something climbers regard as at least as much of a challenge as the summit itself. A few hours before he got there, Lakba Gelu Sherpa arrived at the top of Everest in record time. He took just under eleven hours to go from base camp to the summit - a journey that takes the average climber a good four days of hard climbing. His achievement breaks the world record set just a couple of days ago by a fellow Sherpa, Pemba Dorje, who got to the top of the mountain in twelve-hours-forty-five minutes. VOCABULARYsummit - vrchol tears of joy - slzy radosti be grateful - být vděčný, považovat si challenge - "výzva" achievement - významný čin, životní úspěch to break the world record - překonat světový record
