Shortly afterwards, the ass found that he had         (heavy) loads to carry and harder work in the brick-field, and asked for another change again. God, telling him that it would be        last time that he could satisfy his request, made him sold to a tanner (皮革工). The ass found that he        (fall) into worse hands. Knowing his new master’s occupation, he said, “It would have been better for me either to have been starved by the first owner        to have been overworked by the second. But now I have already been bought by my present owner,        will peel off my skin even after I am dead, and make me useful .”
