{{B}}TEXT D{{/B}}

When I appeared before you on a previous occasion, I had seen nothing of American art save the Doric columns and Corinthian chimney-pots visible on your Broadway and Fifth Avenue. I find that what your people need is not so much high imaginative art but that which hallows the vessels of everyday use.
I suppose that the poet will sing and the artist will paint regardless whether the world praises or blames. He has his own world and is independent of his fellow-men. But the handicraftsman is dependent on your pleasure and opinion. He needs your encouragement and he must have beautiful surroundings.

[单项选择]One of the qualities that most people admire in others is the willingness to admit one’s mistakes. (79) It is extremely hard sometimes to say a simple thing like "I was wrong about that," and it is even harder to say, "I was wrong, and you were right about that. "
I had an experience recently with someone admitting to me that he had made a mistake fifteen years ago. He told me he had been the manager of a grocery store in the neighbor-hood where I grew up, and he asked me if I remembered the egg cartons. Then he related an incident and I began to remember vaguely the incident he was describing.
I was about eight years old at the time, and I had gone into the store with my mother to do the weekly grocery shopping. On that particular clue, I must have found my way to the dairy food department where the incident took place.
