Long long ago, there was a man who lived in a village. One day, he went to a market and did some {#blank#}1{#/blank#} (shop). He {#blank#}2{#/blank#} (sudden) found two boxes. Both the two boxes {#blank#}3{#/blank#} (be) very beautiful and the man fell in love with them at the first sight. So he bought them.

    After he got home, he didn't know how to use the two boxes. He thought it over and decided to do something {#blank#}4{#/blank#} (specially). He decided to put all of his happiness in the yellow box and all of his sadness in the black box. He thought that it was funny to do that.

A few days {#blank#}5{#/blank#} (late), the yellow box was very heavy, {#blank#}6{#/blank#} the black box was still light.

    He didn't know {#blank#}7{#/blank#}. He decided to open the two boxes and found out the  {#blank#}8{#/blank#} (true). He opened the yellow box and found nothing. Then he opened the black box and saw {#blank#}9{#/blank#} hole at the bottom (底部).

    Then he smiled to {#blank#}10{#/blank#} and said, “Happiness is for me. Let sadness go.”
