Carver studied peanuts.He knew that the south couldn't grow just cotton. Planting cotton year after year wore out the soil and made it useless.Carver learned that if farmers planted cotton one year and peanuts the next,the soil{#blank#}1{#/blank#}healthy.

    To encourage this practice,Carver thought of new uses for the peanut.Would you like to try peanut and raisin ice cream? How about using peanuts as a kind of{#blank#}2{#/blank#} to make shampoo? Perhaps you would prefer to make paint from peanuts,or maybe you would like to bake with peanut flour.Glue? Paper? Rubber? The list goes on and on.He also thought of{#blank#}3{#/blank#}uses for pecans (山核桃）and other nuts.

    Carver{#blank#}4{#/blank#}little from most of his inventions.He didn't feel that it was right to sell his ideas. He gave them freely to help farmers and fellow scientists.Carver's life is one that we could all use as an example.

    Once upon a time, a father and his son were walking from one town to another, While they {#blank#}1{#/blank#}, they happened to pass by a river. They were tired and stopped there {#blank#}2{#/blank#}. Then the father asked his son to get him some water from the river.

    Then the son walked to the riverside and he {#blank#}3{#/blank#}some women washing clothes there. Right at that moment, a bullock cart(牛车) started crossing the river. As a result, the water became very dirty. “I mustn't take the dirty water to my father,” he thought. So he came back and said. “Look, Father. A bullock cart {#blank#}4{#/blank#}the river now, so the water is dirty and it can't be drunk.” Father said nothing.

    After a while, the son {#blank#}5{#/blank#}to get some water again by his father. The water was still dirty, but he didn't go back. He thought, “My father is so thirsty. I {#blank#}6{#/blank#}back clean water this time, even though it will take me a long time.” Then he sat there, waiting until the water was clean. He collected some in a bowl and took it back.

    “Oh, you are back at last, I {#blank#}7{#/blank#}for you for almost half an hour.” Father said. After {#blank#}8{#/blank#}the water, he looked up at his son and said, “Now, {#blank#}9{#/blank#}about what made the water clean. You let it be and the water became clean on its own. It is also the same with your mind. When it is disturbed(打扰), just let it be, and it will calm down on its own.”

    The son thought for a while and said, “Thank you, Father. I {#blank#}10{#/blank#}this forever.”

    We can make best decisions when we stay calm.
