When student complete a first draft, they consider die job of writing done — and their teachers too often agree. When professional writers complete a first draft, they usually feel that they are at the start of the writing process. When a draft is completed, the job of writing can begin. That difference in attitude is the difference between amateur and professional, inexperience and experience, journeyman and draftsman. Peter F. Drucker, the prolific (高产的) business writer, calls his first draft "the zero draft" —after that he can start counting. Most writers share the feeling mat the first draft, and all of those which follow, are opportunities to discover what they have to say and how best they can say it. To produce a progression of drafts, each of which says more and says it more clearly, the writer has to develop a special kind of reading skill. In school we are taught to decode what appears on the page as finished writing. Writers, however, face a different category of possibility and responsibility when they read their own drafts. To them the words on the page are never finished. Each can be changed and rearranged, can set off a chain reaction of confusion or clarified meaning. This is a different kind of reading, which is possibly more difficult and certainly more exciting. Writers must learn to be their own best enemy. They must accept the criticism of others and be suspicious of it; they must accept the praise of others and be even more suspicious of it. Writers cannot depend on others. They must detach themselves from their own pages so that they can apply both their caring and their craft to their own work. Such detachment is not easy. Science fiction writer Ray Bradbury supposedly puts each manuscript away for a year to the day and men rereads it as a stranger. Not many writers have the discipline or the time to do this. We must read when our judgment may be at its best; 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 is 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, added 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). Why does Ray Bradbury put each manuscript away for a year before he rereads it
A. Because he does not like his own work.
Because he feels writing is dreadful.
C. Because he is a person of principle.
D. Because he needs to detach himself from his own work.

The view over a valley of a tiny village with thatched (草盖的) roof cottages around a church; a drive through a narrow village street lined with thatched cottages painted pink or white; the sight over the rolling hills of a pretty collection of thatched farm buildings in these are still common sights in parts of England. Most people will agree that the thatched roof is an essential part of the attraction of the English countryside. Thatching is in fact the oldest of all the building crafts practiced in the British Isles (英伦诸岛). Although thatch has always been used for cottage and farm buildings, it was once used for castles and churches, too. Thatching is a solitary (独自的) craft, which often runs in families. The craft of thatching as it is practiced today has changed very little since the Middle Ages. Over 800 full-time thatchers are employed in England and Wales today, maintaining and renewing the old roofs as well as thatching newer houses. Many property owners choose thatch not only for its beauty but because they know it will keep them cool in summer and warm in winter. In fact, if we look at developing countries, over half the world lives under thatch, but they all do it in different ways. People in developing countries are often reluctant to go back to traditional materials and would prefer modem buildings. However, they may lack the money to allow them to import the necessary materials. Their temporary mud huts with thatched roofs of wild grasses often only last six months. Thatch which has been done the British way lasts from twenty to sixty years, and is an effective defense against the heat. Which of the following remains a unique feature of the English countryside
A. Narrow streets lined with pink or white houses.
B. Rolling hills with pretty farm buildings.
Cottages with thatched roofs.
D. Churches with cottages around them.
