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

    No one knows.This mystery（谜）has puzzled（困惑）the world（世界）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（无、没有）shoes in the snow!

    In 1906, another climber saw more than footprints. Far off, he saw a very large animal standing on two legs. When 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（穿过）the snow, far below him. He said it looked like a very large man.

    From then on, more and more people had stories to tell. But not until 1951 did a mountain climber bring back pictures of large footprints. The pictures showed that the Snowman walked on two legs. So it was not a bear or a monkey. Could it be an ape（猿）man? The mystery grew! And the mystery keeps growing. Someday we may find out just what it is that makes the large footprints.

    Most children don't enjoy doing chores. They like playing computer games rather than cleaning the rooms. But in Australia, Jim and Robert's mother, Mrs. Black, has good and proper methods to get their children to do housework.  

    Here is an example.

 “Mom, have you worked out next week's chores? Let Jim and me choose the cards. I can't wait. It's fun! ”

    When Robert shouted out, his mother had already put all the cards on their big table. On the cards, there are some words like these, “sweep the floor, clean your bedroom, help mom cook, wash vegetables, make beds, feed the fish, cut the wood, clean the bathroom”and many others, Jim and Robert chose two cards for each day from Monday to Friday. Then they would hang them on the weekday task board. Jim likes to clean the bathroom, so he picked up the card “clean the bathroom”. Robert loves to make the bed so he picked up his favorite card. Jim again picked up “wash vegetables” and Robert chose “feed the fish”. Soon the two boys were happy to take away all the cards.

    To help the children do chores, their mother thought hard and came up with this idea. Of course, the parents did the chores at weekends and left Jim and Robert two days free.
