My Aunt Edith was a widow（寡妇） of 50, working as a secretary, when doctors discovered what was then thought to be a very serious heart disease.Aunt Edith didn't accept defeat easily. 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, of Houston, Texas. He had saved the life of someone with the same disease. The article said his fees were very high; Aunt Edith couldn't possibly pay them. But could he tell her of someone whose fees she could pay?So Aunt Edith wrote to him. She simply listed her reasons for wanting to live: her three children, who would be on their own in three or four more years; her little-girl dream of traveling and seeing the world. There 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 DeBakey191.Aunt Edith（） when she knew she had a very serious heart disease.A.stopped working as a secretaryB.didn't lose hopeC.stayed in the hospitalD.asked many doctors for help192.From the story we can see（）.A.Dr.Michael DeBakey was not famous at allB.Aunt Edith could afford Dr.Michael DeBakey's feesC.Dr.Michael DeBakey was experienced in dealing with Aunt Edith's diseaseD.Aunt Edith accepted defeat easily193.In Aunt Edith's letter to the doctor,（）.A.she showed she was warm, humorous and enjoying livingB.she avoided talking about her childrenC.she showed she was very sadD.she said she had a little girl who dreamed of traveling and seeing the world194.When Aunt Edith mailed her letter,（）.A.she was determined to move the doctorB.she expected some wonder would happenC.she knew it would never reach the doctorD.she didn't expect the doctor would give her a reply195.Michael DeBakey mainly told Aunt Edith in the letter that（）.A.he was going to operate on her for freeB.he thought he was unable to offer helpC.her letter was well-writtenD.her disease was so serious that he couldn't cure her
