Mr Black was over fifty
years old. He sometimes made some {#blank#}1{#/blank#} (mistake) in his work, and he lost his work. So
he {#blank#}2{#/blank#} (have) lots of free time to do something.
Then he often met his old friends under a big tree. There they talked {#blank#}3{#/blank#} anything they liked.
One day, some old men were {#blank#}4{#/blank#} (sit) together again and talking about young
people in this world. They all agreed that the old people were {#blank#}5{#/blank#} (clever) than young people. Then one of the
old men said that young {#blank#}6{#/blank#}(man)
were stronger than old men. All of them agreed that this was true, but Mr Black
didn't. He said, "No, now I am as strong as when I was {#blank#}7{#/blank#} young man." His friends were {#blank#}8{#/blank#} (surprise) at what he said.
"Well," said Mr Black. "Near my
house, there is a big stone. When I was a young man, I tried {#blank#}9{#/blank#} (move) it, but I couldn't because I was not
strong enough. I am an old man now, and {#blank#}10{#/blank#} I try to move it, I still can't. So I am as
strong as when I was young. "
