Do you know what special birthday presents the German Chancellor Schroeder(德国 * * 施罗德)gave his mother?

In 1990, he took her to lunch in a Mercedes(奔驰)car for her 80th birthday.

Schroeder’s family was very poor when he was young. Once his grandma had to steal(偷)meat from their neighbors. That was the only way to give the family a good supper. His mother was very sad and cried about it. Young Schroeder held his mother in his arms and said, “Mom, one day I’ll take you out in a Mercedes.” Forty years later he made these words come true.

Schroeder gave the old lady a second special present ten years later.

His father died before he was born. He was killed in World War II. His family didn’t know where his grave(坟墓)was. So Schroeder gave his mother a map on her 90th birthday. This map was very special. It showed where his father’s grave was. The old lady smiled happily at the surprising gift. Then Chancellor held his mother in his arms and kissed her face.
