材料一 徐州古丰县，有村曰朱陈。击县百余里，桑麻青芬盈。机援声札札，牛驴走纷纭。女汲涧中水，男采山上薪。县远官事少，山深人俗淳。有财不行商，有丁不入军。家家守村业，头白不出门。……

材料二 如图

19世纪90年代，天津武举李福明在北京开办一家机器面粉厂，使用外国进口蒸汽机磨，每天能磨面粉200石。京城官府见机器面粉厂生意兴隆，就存心勒索。李福明不甘忍受压迫，到官府去讲理。结果，官府给他扣上“私设磨坊”、“哄闹官署”等罪名，革去他的武举功名，“交刑部照例治罪”。李福明的机器面粉厂被迫关闭。

There are two things I can count on my dad asking every time he calls me: “Is there anything I can do for you?” and “How’s the car?” I guess he asks what he can do for me because his dad (an air force officer) was never really there for him, and he’s determined to provide me with the support he lacked. During my youth he never missed a school play or softball game. In fact, he was so supportive that I sometimes longed for one of those dads who dressed better and cared less. But my dad would forever be the guy wearing shorts with dress shoes and black socks, cheering me on, expecting greatness.

His other standard question—How’s the car? -- used to strike me as a waste of long-distance dollars from a man who once suggested making a list of what you want to talk about before calling someone out of state. What I now realize is that “How’s the car?” is not about the car. It’s a father’s way of asking his adult daughter how she is doing. The advantage is that if there’s something wrong with the car, he knows what to do about it and how much it will cost, whereas if you’re having problems about marriage or doubting a career choice, he might have to act Mom on the line.

At age thirty I finally took the plunge(跳进) into adulthood by renting a car without my dad’s help or advice. I’m sure my dad was hurt rather than proud. Though a daughter’s independence is evidence of a job well done, it still implies the job’s done, and many fathers are unwilling to retire. Even when my dad was overworked, he’d happily jump on a plane if I said I needed help. His frequent question “Is there anything I can do for you?” underlines the fact that he wishes there was still something he could provide. It’s interesting: Even though we’re tied by blood and I love him no matter what, he still seems to need a concrete function -- suggesting stocks, finding the cheapest plane fare -- to feel he has a role in my life.
