A

My father came to the United States as a Ukrainian immigrant (移民)when he was 14 years old. Unable to speak English but willing to do anything to succeed, he learned the language, and became a barber. He put his two daughters, my sister and me, through college during a time when most people thought that women didn’t need an education and that they should be satisfied by getting married and having children.

I was preparing to get married and my father was trying to practice the polka, a must at any Ukrainian wedding. But he couldn’t do it! He had lost the mobility(活动能力)in his leg and suffered a brain tumor(瘤). He was forced to retire as a result of paralysis(瘫痪)of his right arm and leg. Dad had always worked two jobs and spent his spare time working around the house. Now his life came to a sudden stop. Yet never once did he complain. He bought rubber balls and spent his days trying to regain his hand mobility by squeezing those balls over and over.

After his second brain operation, he chatted pleasantly in the hospital room until a nurse flew into the room, waving her finger at me, and yelling, “You’d better tell your father to stay in bed. He is paralyzed and will never walk again. I am sick of picking him up and you’d better warn him to stay put!” My father smiled. He spent a great deal of time on the floor that year, but he eventually got up and walked.

My father lived nineteen more years after that second brain operation. He bought himself a motorized scooter(单脚滑行车)and spent years moving around the streets of Philadelphia. He was proud, free and always smiling.
