Passage 3

?

　　A friend of mine was fond of drawing horses. He draw the horses very well, but he always begins with the tail. Now it is the Western rule to begin at the head of the horse, which is why I am surprised. It strikes me that it could not really make any difference whether the artist begins at the head or the tail or the belly or the foot of the horse, if he really knows his business. And most great artists who really know their business do not follow other people's rules. They make their own rules. Every one of them does his work in a way peculiar to himself; and the peculiarity means only that he finds it easier to work in that way.一网一平台答案

　　Now the very same thing is true to literature. And the question, "How shall I begin?" only means that you want to begin at the head instead of beginning at the tail or somewhere else. That is, you are not yet experienced enough to trust your own powers. When you become more experienced you will never ask the question, and I think that you will often begin at the tail - that is to say, you will write the end of the story before you have even thought of the beginning.

A. ?very well

B. in the way of western rule
