参考答案：A
My dad was a fisherman. He worked hard and stayed out until he caught enough 36 to feed the family nearly every day. When the weather was bad he would 37 me to school. An old truck was used in his fishing business. When we got to the school, he would give me a big 38 on the face and tell me to be a good 39 . It was so embarrassing for me. I was 12 years old, and my dad would still kiss me goodbye! I remember the day when I decided I was too 40 for a goodbye kiss. When we got to the school and came to a stop, he had his usual big smile. He started to lean (倾斜) toward me, but I put my hand up and 41 , “No, Dad.” It was the first time I had ever talked to him that way. He had a surprised look on his face for a long time, and his 42 started to be wet. He turned and looked out of the windshield (挡风玻璃). “You’re 43 ,” he said.“You are a big boy—a man. I won’t kiss you any more.” It wasn’t long after that when my dad went out to 44 and never came back. It was a day when most of the fishermen stayed at home except Dad. He had a big family to feed How I wish I had been a man then. If I had been a man, I would 45 have told my dad I was too old for a goodbye kiss.
