You don't have to give thousands of dollars to help someone . Sarah，a girl from Michigan，the USA ,makes a difference just by giving her {#blank#}1{#/blank#} . Sarah was seriously in {#blank#}2{#/blank#} she was a baby. It is {#blank#}3{#/blank#} for her to move．Sarah has to {#blank#}4{#/blank#} around with a walker，however，the 11-year- old girl doesn't give up, and she uses her experience to help others.
Last summer , Sarah {#blank#}5{#/blank#} three days a week for seven weeks at the Grand Rapids Comprehensive Therapy Center.

Sarah says that she's {#blank#}8{#/blank#} she can share knowledge with others , and that working at the center taught her a lot, "I feel my life is getting better because I can help others in {#blank#}9{#/blank#} way.”she said .Mary, Sarah's fourth - grade teacher said that Sarah has the help of other students around her , but shows than that she's there to {#blank#}10{#/blank#} them , too.

    “Today is my birthday”, Sarah said. “I hope there will be a big party {#blank#}1{#/blank#} all my friends!” She looked around the house,{#blank#}2{#/blank#} nobody was there. She was sad that her parents and friends forgot{#blank#}3{#/blank#}(she) birthday.

She decided to have a party on her own. “I'll invite my dolls and my favorite Teddy Bear to my party.” Sarah gave all her dolls a ride to the party in her wagon(马车). She also {#blank#}4{#/blank#} (make) a cake by{#blank#}5{#/blank#} (she).

    Is there something strange high up in the world's {#blank#}1{#/blank#} mountains? If so, is it a big bear? Is it monkey? Or is it a kind of man?

    No one knows. This mystery has puzzled the world for years.

    In 1887, a mountain climber found large footprints in the snow. They looked like the footprints of a very large man. But men don't walk {#blank#}2{#/blank#} shoes in the snow!

    In 1906, another climber saw more than footprints. Far off, he saw a very large animal standing on two legs. As he watched, it ran very {#blank#}3{#/blank#}.

Fifteen years later, newspaper had new stories about the "something". A mountain climber said he had seen the "{#blank#}4{#/blank#}" walk slowly across 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 of large footprints. "The pictures showed clearly {#blank#}5{#/blank#} 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 growing. Some day we may {#blank#}6{#/blank#} what it is that makes the large footprints.
