[简答题]My brother had some clever men among his friends whose writings added to the success of the newspaper. These gentlemen often visited us. Hearing their conversation, and their accounts of the approval their articles had received, I became excited and decided to write a piece of my own. But still being a boy, and suspecting that my brother would object to printing anything of mine, I wrote an article and left it unsigned. At night, I put it under the door of the printing house. It was found in the morning, and shown to his writing friends when they came to visit. They read it and gave their opinions. I had the wonderful pleasure of finding it met with their approval, and that, in their different guesses as to the author, they named men of learning and imagination. I suppose now that I was lucky in my judges, and that perhaps my writings were not as good as I then thought.
