I was happy to see her back. My little “Mr. Clean” and I went to the shopping mall.“Daddy, can I get a gift?” “OK, but just one,” I said. I asked her what she wanted. Without thinking twice, she said “An ice-cream comb(梳子) from the ice-cream store.”At the end of the road, she found something new－a big fountain(喷泉）.“Daddy, can I make a wish?” she jumped with joy. “Sure honey, but that will be your gift you know,” I told her. She agreed.I put a coin in her hand. She closed her eyes and made her wish. “Can you tell Daddy what you wished for?” She answered, “I wished I could get an ice- cream comb.” Finally, she got her wish, and two gifts.I knew that my beautiful girl would soon be on a long road of surgeries, special schools, endless treatments and end up paralyzed(麻痹) on her right side.Today, she is almost seventeen. She can't use her right hand and walks with a limp(跛行). But each year she shows improvement. She is planning a job in early childhood education. With one year before finishing high school, she and I planned all the subjects she would need to take in college. It was her idea. You see that “giving up” was never a choice to her.【1】Why did the writer call her daughter “Mr. Clean”?___________________________________________________【2】What was the little girl’s wish?__________________________________________________【3】How did the girl feel when she saw the fountain?__________________________________________________【4】Is the writer’s daughter as healthy as other common girls now?__________________________________________________【5】What spirit do the writer’s daughter and Aron Ralston (the man in Unit 1 who cut off his arm to save himself )have in common?__________________________________________________
