Is there anything strange on the top of the world's highest mountains? If so, is it a bear? Is it a monkey? Or is it a kind of man?

    No one 1. The world has tried their best to know more about this mystery (神秘) for years. In 1887, 2 mountain climber found very big footprints of a very large man. 3 man doesn't walk barefoot（光脚）in the snow. In 1906, 4 climber saw more than footprints. To his surprise, he saw a great hairy animal 5 on two legs. As he watched, it ran out of sight（视线）.

    Fifteen years later, there were 6 about the thing in the newspapers. A mountain climber said that he had seen the “snowman”   7 slowly across the snow, far below him. He said it looked like a very large hairy man.

    From that time on, more and more people had stories to tell. But not until 1951 did a mountain climber bring back 8 of giant (巨大的) footprints. The picture showed 9 that the snowman walked on two legs. So it was not a bear or a monkey. Could it be an ape man? The mystery grew!

    And the mystery keeps on growing. 10 men still hunt the snowman in the high mountains. Some day we may find out just what it is that makes the giant footprints.

    Debbie got up early last Saturday morning. She wanted 1 in Green Park with some of her friends. She was very happy about it.

    2  she was ready， she got on her bike and left for the park – it was on the other side of the town. Suddenly， as she was riding fast， she 3  sirens (警笛). The sound of the sirens was getting 4 ， so Debbie looked 5  her to see what was happening. As a result (结果)， she fell off her bike and lay in the middle of the road. Luckily， Debbie wasn't hurt， 6  a car hit her bike. After the car 7 ， two men got out and started running. 8  a police car stopped next to the same car and three policemen got out and started running after the two men. One of the policemen shouted， “Stop the thieves (贼)!”

    9  a policeman came to see Debbie. He thanked her because， in a way， she had helped them 10 .

    I moved to a new neighborhood two months ago. A taxi driver lived in a house with a large1across the road. He's a single parent with two school-age children. At the end of the day, he would2his taxi on the road. "Why not in the garage？"I asked myself.

    Then one day I learned that he had another3. In the afternoon he would come home from work, leave his taxi and go out4his personal business in his other car, not in his taxi. I felt it was5.

    I really want to see his personal car but did not make it. Two weeks later, I6 to be outside one evening, when the garage door was7and he drove out in his "own" car: a Rolls-Royce(劳斯莱斯)! It8 me completely when I realized what that meant. You see, he was a taxi driver. 9deep inside, he saw himself as something else：a Rolls-Royce owner and a(n)10. He drove others in his taxi but himself and his children in his Rolls-Royce. The world looked at his taxi and called him a taxi driver. But for him, a taxi was11something he drove for a living. Rolls-Royce was something he drove for a(n)12.

    We go to bed every night and13every morning as parents or children, not as bankers, CEOs or professors. We go for a party as close friends or go for a vacation as a family. We love life as it is. Yet often, we base our happiness and14on how high we climb the social ladder(阶梯)—how much bigger and better a taxi we have. And we fail to notice Rolls-Royce, keeping it dusty in our garage. We should pay more attention to 15we are than what we do！Isn't it the true meaning of life？

Several minutes later, his mother pointed to the same sparrow and asked the same question again. Mike got a little angry but 2 answered her question. After a little while, his mother did the same thing once more. This time Mike could not 3 his anger. He shouted at her for disturbing him again and again.

    The old lady silently 4 an old diary, turned to a page and showed it to Mike. Though a little impatient, Mike began to read it.

    After a while Mike asked me again and I did the same. Pointing to the same sparrow, little Mike asked me what it was twenty times and I 7 answering his question and kissing him every time.

    Something gently touched Mike's 8. His face turned red with 9 for being so impatient to his mother and he hugged (拥抱) her tightly.
