10、strange attacked a young girl called Lhakpa Dolma. When the police saw the footprints of the attacker, they were frightened. The footprints were huge! “What kind of beast is this?” the people asked. Lhakpa lived in the village, and every day she went up the mountain with her yaks(a kind of cow) so t

11、hat they could eat the grass. Lhakpa knew exactly where to find the sweet, green grass for her yaks on this special mountain, which was called Mount Everest and is famous because it is the highest mountain in the world. “Arent you frightened to walk in the mountains alone, Lhakpa?” asked her friends

12、. “What about the yeti?” But Lhakpa was not frightened. “The mountains of the Himalayas are huge!” she laughed. “I only go to one small place, not far from the village. And no one here has veer seen a yeti-its only a story.” So Lhakpa never really thought about the old yeti tales while she was worki

13、ng. One day in 1974, Lhakpa took her yaks up the mountain as usual, but she could see that the yaks were not happy. “Perhaps they can smell a bear or a snow leopard near us,” she thought, and looked around. Lhakpa couldnt see anything, but she moved away. She took the yaks to another place, near a s

14、mall stream. The water here came from the mountain snow and Lhakpa drank a little-it always tasted good! Then she sat down and watched her yaks eating.

She shouted and kicked, but it was no good - the yeti was too strong. “Help me!” she shouted. But the mountains were

16、quiet, and nobody heard her. But the huge beast was not really interested in Lhakpa - perhaps she was too small. It put her down in the cold mountain stream, then it turned round and looked at the yaks, which were big and strong- but the yeti was bigger. Lhakpa watched the yeti- she was too terrifie

17、d to move at first. With its strong arms, it quickly killed three of the yaks. Then Lhakpa got out of the stream and ran home. She was frightened and cold. She told her parents about eh yeti killing the yaks. Her family were amazed at the story. They soon went to the police after they learned about
