     I don't know how I became a writer, but I think it was because of a certain force in me that had to write

and that finally burst through and found a channel. My people were of the working class of people. My father,

a stone-cutter, was a man with a great respect and veneration (崇敬) for literature. He had a tremendous

memory, and he loved poetry, and the poetry that he loved best was naturally of the rhetorical kind that such

a man would like. Nevertheless it was good poetry, Hamlet's Soliloquy, Macbeth, Mark Antony's "Funeral

Oration", Grey's "Elegy",and all the rest of it. I heard it all as a child; I memorized and learned it all.

     He sent me to college to the state university. The desire to write, which had been strong during all my days

in high school, grew stronger still.I was editor of the college paper, the college magazine,etc., and in my last

year or two I was a member of a course in play writing which had just been established there. I wrote several

little one-act plays, still thinking I would become a lawyer or a newspaper man,never daring to believe I could

seriously become a writer. Then I went to Harvard, wrote some more plays there,became obsessed with (着迷

于) the idea that I had to be a playwright, left Harvard, had my plays rejected, and finally in the autumn of 1926,

how, why, or in what manner I have never exactly been able to determine. But probably because the force in

me that had to write at length sought out its channel, I began to write my first book in London. I was living all

alone at that time. I had two rooms-a bedroom and a sitting room-in a litter square in Chelsea in which all the

houses had that familiar, smoked brick and cream-yellow-plaster look.
