The Umbrella(雨伞)

     A  gentleman staying  in a hotel left his umbralla in the hall, but he had put on the handle a card on which was written：" This umbrella belongs to a gentleman who can lift up(举起) a hundred pounds . I shall be back in ten  minutes ."

     When he  came back, he found ,instead of his umbrella ,another card on which was written：" This card belongs to a man who can run ten miles an hour, i shall not come back !"
