45、t; when we are close to the best moment of creation. Most people think that the principal problem is that writers are too proud of what they have written. Actually, a greater problem for most professional writers is one shared by the majority of students. They are overly critical, think everything i

46、s dreadful, tear up page after page, never complete a draft, see the task as hopeless. Therefore, the writer must learn to read critically but constructively, to cut what is bad and reveal what is good. At the end of each revision, a manuscript may look worked over, torn apart, pinned together, adde

47、d to, deleted from, words changed and words changed back. Yet the book must maintain its original freshness and spontaneity (原创性，创作冲动). （分数：177.50）(1).What is the difference between a student and a professional writer towards their first draft?（分数：35.50）A.A professional thinks his first draft is better planned.B.A student is less confident than a professional about the first draft.C.A student will read his first draft more seriously than a professional.D.A student sees the draft as his final work, while profes
