A【B1】______physician, who was lying on his deathbed, was surrounded by sever

A(11)famous physician(内科医生), who was lying on his deathbed, was surrounded by several fellow physicians, who were weeping at his loss.
    When the(12)dying man observed it, he comforted them, by saying, "Don’t weep, gentlemen, because I must die. It is not such a great loss to the world as you think, for I shall leave three great physicians behind me."
    Every one of them(13)believed that he was one of the three. So they pressed him very much, to tell them, who the well-known men were.
    "They are: Water,(14)Exercise and Temperance," he replied.
    One may easily imagine how surprised and disappointed they were, when they received this(15)unexpected answer.
