I first met Sean one summer day. He carried a bag    36 with four clubs(球杆)  and some balls. He was a lot   37  than other kids of his age. I heard he was   38   from cancer. Still , he always seemed to be smiling whenever I would see him with his friends, trying to  39  as far as he did.
A year or so passed and I hadn’t   40  Sean .I had heard that his cancer was   41      him. Still, his friends said he was going to come here before long.
  42  enough , he was there the following week. I   43  that one of his friends was carrying Sean’s bag. I saw Sean was having a(n)  44  time trying to drive the ball. Sean hit his last ball as hard as his fragile body would   45  .It flew up to the green and was out of sight. One of his friends   46  Sean walk up to the green. It was a(n)  47 walk because the green was higher than the tee(发球区).
Suddenly I saw one boy pick up Sean’s ball and    48  it in the hole. Then he ran and   49  to look for his own ball.
When Sean finally got to the green, he looked   50  because he thought he hit it over .
Then he glanced in the hole. A smile   51  his face! The boys looked at each other and said , “You can’t tell me it’s a hole-in-one!”
“No, really ! Look !” he said . They all acted    52  and as I watched , I thought Sean looked like the   53   guy I had ever seen. I never saw Sean or his friends after that day.   54   it was then that I learned just what golf should be .
It’s not about what   55  you get or how far you drive. It is about caring for the friends you play with and enjoying the time you have with them.
