Back in the fifteenth century in Nuremberg lived a family with eighteen children. They were so poor that two children, who wanted to pursue their talent for  26 knew their father would never be   27  able to send  either of them to Nuremberg to study at the Academy.
So they tossed (掷) a coin. Albrecht Durer, the younger, 28   the toss and went off to Nuremberg. Albert went down into the dangerous  29  and for the next four years, financed his brother, who did so well that his works were even better than those of most of his  30 . By the time he graduated, he was beginning to earn  31  fees by drawing for wealthy people. When the young artist returned home, at dinner he drank a  32 to his beloved brother for the years of  33 that had enabled him to fulfill his  34 .He said, “Albert, my blessed brother, now it is your 35 to go to Nuremberg to pursue your dream, and I will take care of you.”
With tears in his eyes, Albert held his hands close to his right cheek and said, “No, brother, I cannot go. Look... look what four years in the mines have done to my  36  !The bones in every finger have been  37 at least once. Lately I have been suffering from arthritis (关节炎) so badly in my right hand that I cannot even hold a  38  to return your toast, much less make delicate (细腻的)lines with a pen or a brush. No, brother..., for me it is too  39  .”
Deeply moved, Albrecht painstakingly drew his brother’s  40  hands with palms(手掌) together and thin fingers stretched skyward. He called his powerful drawing  41 “Hands”, to which the entire world  immediately opened their hearts and later they  42 it “ the Praying Hands”.                                  
The next time when you see a copy of that  43  creation, take a second look. Let it be your  44  , if you still need one, that no one ever makes it  45  !
