    There was no one quite like my father in our town. When any other man had an extra dollar, he bought a drink; when Father had an extra dollar, he bought a book. Other people had pictures on their walls; we had books, 3000  of them, lining every vertical surface of our little four-room house.

Father was the most persistent scholar I ever knew. He earned seven degrees, attended 11 different colleges and universities, and in 1951, when he was 82, sent us a cheerful little note from England to say that he had just enrolled for a graduate course in Elizabethan literature at Oxford.

I was the immediate beneficiary of Father's unbelievable hunger to learn. Every spring, he would take me hiking through the mountains to study mineral formations. On clear winter nights, he would set up a telescope and wake me to view the stars. After I grew up, wherever I traveled around this earth, the stars remained my friends.

Plain, distinct speech was a particular concern of my father and he was constantly drilling me in the art of elocution （演讲技巧）.Before I was three, he was reading aloud to me from the Bible, Shakespeare and Mark Twain. Thereafter, read aloud to him so he could work on my diction. By the time I was in the fifth grade, I could recite from a whole range of classical literature and poetry.

Of course, there had been times as a young man, when I got tired of study and devoted my time to playing. Then Father would admonish me succinctly by quoting a saying from Shakespeare, "If all the year were playing holidays, to sport would be as tedious （乏味的）as to work."

Obviously, his efforts were not entirely in vain, for my voice has enabled me to earn a fair livelihood. But that fact doesn't begin to define the enormous debt I owe my father.
