  Is there a strange something high up in the world’s tallest mountains? If so, is it a big bear? Is it  a monkey? Or is it a kind of man?

No one knows. This mystery (谜) has puzzled (困惑) the world for years.In 1887, a mountain climber found large footprints (脚印) in the snow. They looked like the footprints of a very large man. But men don’t walk without shoes in the snow!

In 1906, another climber saw more than footprints. Far off (遥远的)saw a very large animal standing on two legs. As he watched, it ran very quickly.

Fifteen years later, newspapers had new stories about the “something”. A mountain climber said he had seen the “snowman” walk slowly across the snow, far below him. He said it looked a very large man.

From then on more and more stories to tell. But not until 1951 did a mountain climber bring back pictures of large footprints. The pictures showed clearly that the Snowman walked on two legs. So it was not a bear or a monkey growing. Someday we may find out just what it is that makes the large footprints.
