阅读理解。 Both my parents came from towns in Mexico. Then I was born in El Paso, Texas,and when I was four, my family moved to a housing project in East Los Angeles. Even though we struggled to make ends meet, my parents stressed to me and myfour brothers and sisters how fortunate we were to live in a great country with limitless opportunities. They influenced us with the concepts of family, faith and nationalism. I got my first real job when I was ten. My dad injured his back working in a cardboard-box factory and was retrained as a hairstylist. He rented space in a little shopping mall and gave his shop the fancy name of Mr Ben's Coiffure. The owner of the shopping center gave Dad a discount on his rent for cleaning the parking lot three nights a week, which meant getting up at 3 a.m.. To pick up rubbish, Dad used a little machine that looked like a lawn mower. Mom and I emptied garbage cans and picked up litter by hand. It took two to three hours to clean the lot. I'd sleep in the car on the way home. I did this for two years, but the lessons I learned have lasted a lifetime. I acquireddiscipline and a strong work ethic (道德), and learned at an early age the importance of balancing life's competing interests-in my case, school, homework and a job. This really helped during my senior year of a high school, when I worked 40 hours a week flipping burgers at a fast-food joint while taking a full load of college preparation courses. The hard work paid off. I attended the US Military Academy and went on to receive graduate degrees in law and business from Harvard. Later, I joined a big Los Angeles law firm and was elected to the California State Assembly (州议会). In these jobs andin everything else I've done, I have never forgotten those nights in the parking lot. The experience taught me that there is dignity in all work and that if people are working to provide for themselves and their families that is something we should honor. 1.
