He has been called the “missing link”. Half-man，half-beast. He is supposed to live in the highest mountain in the world — Mount Everest.

He is known as the Abominable Snowman. The  41  of the Snowman has been around for  42 . Climbers in the 1920s reported finding marks like those of human feet high up on the side of Mount Everest. The native people said they  43  this creature and called it the “Yeti” ，and they said that they had  44  caught Yetis on two occasions  45  none has ever been produced an evidence.

Over the years，the story of the Yetis has  46  . In 1951，Eric Shipton took photographs of a set of tracks in the snow of Everest. Shipton believed that they were not  47 the tracks of a monkey or bear and  48  that the Abominable Snowman might really  49  .

Further efforts have been made to find out about Yetis. But the only things people have ever found were  50 footprints. Most believe the footprints are nothing more than  51  animal tracks，which had been made  52  as they melted and refroze in the snow.   53  ，in 1964，a Russian scientist said that the Abominable Snowman was  54  and was a remaining link with the prehistoric humans. But  55 ，no evidence has ever  56  been produced.

These days，only a few people continue to take the story of the Abominable Snowman   57  . But if they ever  58  catching one，they may face a real  59  ：Would they put it in a  60  or give it a room in a hotel?
