【正确答案】 C

【答案解析】[解析] 14-16
Ladies and gentlemen, today's lecture is on how not to grow old, because at my time of life, this is a much more important subject than how to grow old. My first advice would be to choose your ancestors carefully. Although both my parents died young, I have done well in this respect as regards my other ancestors. My maternal grandfather died in the flower of his youth -at the age of sixty-seven, but my other three grandparents all lived to be over eighty. Of remoter ancestors I can only discover one who did not live to a great age, and he died of a disease which is now rare, namely, having his head cut off. A greatgrandmother of mine lived to the age of ninety-two, and to her last day remained a terror to all her descendants. My maternal grandmother had nine children who survived, one who died in infancy. As soon as she became a widow she devoted herself to women's higher education. She was one of the founders of Girton College, and worked hard at opening the medical profession to women. She used to tell of how she met in Italy an elderly gentleman who was looking very sad. She asked him why he was so melancholy and he said that he had just parted from his two grandchildren. "Good gracious," she exclaimed, "I have seventy-two grandchildren, and if ! were sad each time I parted from one of them, I should have a miserable existence!" Speaking as one of the seventy-two, ! prefer her recipe. After the age of eighty she found she had some difficulty getting to sleep, so she habitually spent the hours from midnight to a.m. in reading popular science. I don't believe that she ever had time to notice she was growing old. This, I think, is the proper recipe for remaining young, and this I'd like to share with you.
