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.

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.
