    My dad, “Mutt” Mantle is1 a father to me, sometimes more like a good judge of talent.

    He was 2 about baseball. He made his living working in mines. But he played baseball in several town teams.

    From the day I was born, Dad said he wanted me to make my living as baseball player. He named me Mickey3 a catcher he liked. He hoped I would play for the New York Yankees.

    Dad often 4 a toy baseball to my crib(摇篮). One day, 5. I caught one. Then he was sure that I'd be a ball player!

    I learned about the 6 on a ball field before I learned my ABC's. When I was three, Dad had Mama make me little uniform. He liked to 7 around town in it.

    When I five, I started school. That same day, I had my first 8 in switch-hitting(左右手都能击球)

    Dad and Grandpa were in the yard when I came home from school. They had a small bat and two9“Mickey,” said Dad, “ Grandpa and I have thought up at a new 10. Take this bat and try to hit our

    pitches(投掷).I'm left-handed. When I throw, you swing right-handed 11 you always have. Grandpa's right-handed. When he throws, turn around and swing left-handed.”

    Dad was going to make me a 12 ! He knew that a player who can bat both right and left has a good 13 of making hit.

    That day I tried and tried. But I couldn't swing left-handed. After about 15 minutes, I yelled to Mama for help. She said, “ I know it's easy. But please try.14, to make Dad happy .”

    So, every day after school we had switch-hitting 15. After two weeks, I didn't 16 it any more. My17 were getting trained. I began to hit a few.

    After a year or two, Dad and Grandpa began throwing as 18 as they could. And they put real curves(曲线)on those tennis balls. Then as I grew older, they began to use baseball 19.

    So you know20I, today's baseball star Mickey Mantle, got my star as a Switch-Hitter.

    Once a circle lost one of its wedges (楔子). The circle wanted to be 1, so it went around looking for its missing piece. But 2 it was incomplete and therefore could roll only very 3, it admired the flowers along the way. It chatted with worms. It enjoyed the sunshine. It found lots of4 pieces, but none of them fit. So it 5 them all by the side of the road and kept on 6. Then one day the circle found a piece that fit 7. It was so happy. Now it could be whole, with 8 missing. It incorporated (合并) the missing piece into itself and began to 9. Now that it was a perfect 10, it could roll very fast,11 fast to notice flowers or talk to the worms. When it 12 how different the world seemed when it rolled so quickly, it13, left its found piece by the side of the road and rolled slowly away.

    The 14 of the story is that in some strange sense we are more whole when we are lacking in something. The man who has everything is in some ways a 15 man. He will never know what it feels like to hope, and to nourish (滋养) his soul with the 16 of something better. He will never get the 17 of having someone who loves him give him something he has always wanted or 18 had. When we19 that imperfection is part of being human, and when we can continue rolling through life and 20 it, we will have achieved a wholeness that others can only long for.

    It's a Friday morning in Boston, which1Dr. Jim O'Connell is making his rounds. He might be more2inside an exam room, but that's not where his patients are. Dr. Jim O'Connell is one of a handful of physicians making house calls to the3in the city.

    More than 550, 000 Americans are homeless, and many have health problems but no4to cure. O'Connell and his team are doing something about it. On a daily routine, they5about 700 regular patients. "I feel like I'm a country doctor in the middle of the city." he said.

    O'Connell began to do this 33 years6, when he was at Harvard Medical School and was7to be a one-year position as the founding physician of a new health-care program for Boston's homeless. That turned into a 33-year8at the Boston Health Care for the Homeless Program, one of the country's largest of its kind. O'Connell9about everything, from stitches (缝补)for an arm to surgery for the soul. If patients can't be treated on the street, he finds them a treatment bed at the respite facility(休息治疗区), a place for patients10are too sick to be on the streets11not ill enough for a hospital stay.

    "12I had been taught to do—go fast, be efficient—was13when you take care of homeless people." When you see somebody outside, you get them a cup of coffee and sit with them. Sometimes it14six months or a year of offering a sandwich or a cup of coffee before someone would start to talk to me. But15they engage(参与), they'll come to you any time because of16you. When asked about how his life might have17, if he had become a highly paid physician, O'Connell said, "I18think about it anymore."

    Some things are far more valuable than money. Just ask Dr. Jim O'Connell who19 everything from patients who have nothing20to give.

    Several years ago, my company experienced a slowdown in business. We hoped that it was only 1. We had work enough for only four days of the week. So we decided that we would 2 from Monday through Thursday, and take Fridays to do 3 projects in our hometown.

    One day, we went to a very old gentleman's 4 to do a total cleanup. When we arrived, an elderly woman 5 us at the door. We thought she was the wife, but it turned out she was the 6. She was 75, and her father 97! Soon, we began to 7 the house and the yard. It was 8 how much work a group could get done when everyone was working 9. That gentleman's house went from dirt to a sparkling clean palace by the time we 10.

    The thing I most remember about that day, 11, was not the great cleaning job that we did, but something 12. When we walked into the house, I noticed the wonderful drawings that 13 the walls. The daughter told us that her father had 14 them, and that he hadn't 15 art until he was 80 years old. I was 16: these drawings were works of art that could have easily been hanging in a museum. At the time, I was in my early 30s and wanted to do something that would 17 my creative and artistic competence more than being president of a company would 18. I had felt that it was too 19 to make a change at this "advanced" stage of my life. Boy! My 20 belief system got expanded that afternoon!

    John's parents acquired the washer when he was a small boy. It happened during World War Ⅱ. His family never 1 a washing machine and, since gasoline was expensive, they could not 2 trips to the laundry several miles away. Keeping clothes 3 became a problem for young John's household.

    A family friend joined the army, and his wife 4 to go with him. John's family 5 to store their furniture while they were away. To the family's 6, the friend suggested they use their Bendix. So this is how they 7 the washer.

    Young John helped with the washing, and across the years he 8 a love for the old, green Bendix. But 9 the war ended. When the friends came to take it back, John grew terribly 10. His mother 11 him and said. "You must remember, that machine 12 belonged to us in the first place. That we ever got to use it at all was a gift. So, instead of being mad at it being taken 13, let's use this 14 to be grateful that we had it at all."

    The lesson turned out 15. Years later, John watched his eight-year-old daughter die a slow and painful death of leukemia (白血病). Though he 16 for months with her death, John could not begin getting over from the 17 until he remembered the old Bendix.

    His daughter was a 18. When he realized the simple fact, everything changed. He could now begin recovering from the death of his daughter. He started to see her as a marvelous gift that he was fortunate enough to 19 for a time. He felt 20. He found strength and recovery. He knew he could get through the valley of loss.

    There came a time in my life when my learning curve (曲线) became very steep. I learned so much in such a 1 time that I was reading two grades ahead of my 2 class. At school I was continuously 3 with lectures, because I had already done 4.

    And 5 my knowledge increased, so did my arrogance (傲慢). I started getting into 6 debates with my teachers. I knew more than them, and I was eager to show it at every 7 I got. That was until Mrs T 8. She was new to our school, and a perfect 9 for me. I tried one of my tricks on her in front of the whole class. She didn't scold me. She just 10.

    At the end of the class, she 11 me aside and said the following words:

    "I know that there is an unspoken 12 that a teacher is supposed to be more 13 than the student. We both know that is 14. I know for a fact that you know much more than me. And I won't insult you by pretending otherwise. But remember this. Knowledge is supposed to give you 15, not pride. Today you are the smartest person in the room; tomorrow you won't be. There will always be someone much 16, much more diligent than you. And when that happens, all the pride in the world wouldn't be enough to 17 you from downfall. Everything that you have learnt will be for nothing if you don't learn the 18 of humility."

    Today, I 19 remember her words. I 20 myself of them daily.
