My aunt Edith, working as a secretary, was a single mother. Doctors discovered that she got a very serious
heart disease when she was 50.
1_____ She began studying medical reports in the library and found an article in a magazine about a well-
known heart surgeon (外科医生), Dr Michael DeBakey, in Houston, Texas. He had saved the life of someone
with the same disease. The article said Dr DeBakey's fees (诊疗费) were very high. 2_____ But could Dr
Michael tell her of someone whose fee she could pay?
So Aunt Edith wrote to him. She simply listed her reasons for wanting to be alive. She had three children,
and they would be on their own in three or four more years. 3_____ nere wasn't a word of self-pity-only
warmth and humor and the joy of living. She mailed the letter, not really expecting an answer.
A few days later, my doorbell rang. Aunt Edith didn't wait to come in. She stood in the hall and read aloud:"
Your beautiful letter moved me very deeply. If you can come to Houston, there will be no charge for either the
hospital or the operation. Signed-Michael DeBakey."
That was seven years ago. 4_____ Her three children are happily married. For her age, she is one of the
youngest, most alive people I know-all because of an open-heart surgeon who knew how to honor his
profession, and how to open his own heart.
A. Since then, Aunt Edith has been around the world.
B. Aunt Edith couldn't possibly pay them.
C. Aunt Edith didn't give up.
D. Aunt Edith decided to ask him to save her.
