Reading Comprehension 从下列每篇短文的问题后所给的四个选择项中选出一个最佳答案。 I remember my father John Gary Lewis when he was about the age of 50. Even then, he could work harder than men half his age. It is true that he never smoked or went to movies or parties, but what mattered more is that he believed in working. Even if he was coming down with a cold, he would buy a bag of oranges and sit down and eat nearly the whole bag, instead of going to a doctor. My father was old fashioned in every way: farming, parenting and home care when you were sick. He did his plowing behind mules(骡子) because he thought tractors(拖拉机) would damage the roots of the plants. He was a college professor in North Carolina for 30 years, full-time, and when he wasn't doing that, he was out on his farm, working, sunup to sundown, never taking a vacation, day in and day out, year after year. My four brothers and I grew up in Raleigh in a tough family, guided by the principle that physical strength and endurance are key to survival. I still think of my father at 50 laboring in the hot burning sun, outworking my brothers and me. A long time afterward, when I turned 50, I became a boxer and fought four or five rounds with young kids, three-minute rounds, and I found it quite easy to beat them. The trouble with most of us is that we start to surrender inside once we get between 50 and 60. Our values and interests start to change, and it no longer matters so much who's the winner, especially since we know it's unlikely to be us. In reality, you can still be a winner when you are old; winning truly means being the best of what you are, doing the best you can do, regardless of what anybody else says.
