When he was a young boy,he went to school in the morning,then in the fields till sunset. And then he did his homework during midnight. Life was hard,because they had no ! At the age of 14,my father heard of the United States of America. It was the land of gold,the land where people can become rich. “ don't I go to America?” he thought to himself,full of hope. So,my father came to America. “I had thought it was easy to collect money in America,” he told me. “But when I arrived there,I realized it was not true. They did not like to hire(雇佣) me because I spoke English. Later,I worked in a small restaurant,cleaning up tables, dishes and sweeping the floor. Life was for the first few years. I worked from 10 a. m. to 11 p. m. I wanted to go to school to learn English,but it was impossible. I couldn't the schooling(学费). ” My father working hard,and reached his goal. “Alan,” he often says to me. “If you want something,you have to work for it and never give up. Things do not come really in life. ” That is what I learned from my father.
