Mr Black was over fifty years old.  He sometimes made some   (mistake) in his work, and he lost his work. So he   (have) lots of free time to do something. Then he often met his old friends under a big tree. There they talked  anything they liked.

    One day, some old men were  (sit) together again and talking about young people in this world. They all agreed that the old people were  (clever) than young people. Then one of the old men said that young (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  young man." His friends were  (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  (move) it, but I couldn't because I was not strong enough. I am an old man now, and  I try to move it, I still can't. So I am as strong as when I was young. "
