Back in the 15th century, in a tiny village in Germany, lived a family with eighteen children. Eighteen! In order       to keep food on file table, the father, a goldsmith(金匠)by      , worked almost eighteen hours a day at his trade. Despite their seemingly       condition, two of the eldest children had a dream. They both wanted to pursue their talent for art,       they knew well that their father would never be able to       either of them to study at the Academy.
After many long discussions at night in their       bed, the two boys finally worked out an agreement. They would toss(掷)a coin. The       would go down into the nearby mines and, with his earnings,       his winning brother for the academy. Then, in four years, he would support the other one. Then Albrecht Durer won the toss and       to Nuremberg. Albert went down into the dangerous mines and, for the next four years,       his brother, whose work at the academy was almost an immediate sensation(轰动)- By the time he graduated, he was beginning to       considerable fees for himself.
When the young artist       home and said to his brother, “And now, Albert, blessed brother of mine, now it is your      . Now you can go to the Academy to pursue your dream, and I will       you. ”Albert rose and wiped tile       from his cheeks. “No, brother. I cannot go to Nuremberg. It is too       for me. Look…look what four years in the mines have done to my      ! I cannot even hold a glass, much less make delicate lines on canvas (画布)  __    a pen or a brush.”
More than 450 years have      . By now, among Albrecht Durer’s hundreds of masterful portraits, “The Praying Hands” is one       creation that can catch the world’s hearts.
