    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 my

four 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 acquired

discipline 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 and

in 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.

背景资料：评估对象：国内某大型阀门厂的一条国产I型机组。该机组于2000年4月7日从邻省购置并投入使用，评估人员2005年6月7日（评估基准日）对该机组进行了评估，截止评估基准日，已使用了5.17年，目前处于在用状态中。

评估人员经向该机组生产单位咨询，生产厂商已经不再生产该型号的机组，询得与委托评估同规格的新型设备机组V型号，价格为850000元。

同规格的V型号机组与委托评估的I型机组主要区别在于数控系数的先进程度及结构的改进。经该厂家介绍，数控系统的价值占该机组整体价值的1/8，I型机组并未施用数控系统；由于结构的改进，

价格一般比旧设备增加15%左右，另获悉，I机组的经济使用寿命为15年。

评估人员还了解到，该机组已完成的工作量为机组已运行的时间，标准运行时间为每天运行16小时（两班制），每年运行20天，实际每天运行为18小时。

请用年限法和工作量法计算成新率并评估该机组的价值。
