Writing to learn makes it possible to show learning in writing. Much of the writing you will do in college and at work will ask you to demonstrate what you have learned. The success of that demonstration will depend on, among other things, revising your writing to show your knowledge to best advantage. When you have begun to see what you want to say(frequently this becomes clear at the very end of a first draft), it is time to start thinking about how to present your ideas to others. It is time to start thinking about revising.
Revising can be described as the most important(and frequently most neglected) part of writing. Novelists Doris Lessing has said that many novels miss greatness because authors are unwilling or unable to revise them. James Michener explains the importance of revision this way: "I have never thought of myself as a good writer. Anyone who wants reassurance of that should read one of my first drafts. But I' m one of the world' s great revisers."
Revising takes many forms. It means thinking about the audience for your writing. Who will read your work and why？ It also means developing an overall plan for the writing that will make your ideas clear. Often the organization of a first draft will reflect your process of discovery, but that may not be the best way to present your ideas to someone else. Revising also gives attention to the style. of language, to the structure of a paragraph, and to the shape of sentences and other forms that show learning to its best advantage.
Writing to learn and writing to show learning are never, of course, entirely separate processes. Writers frequently consider issues of demonstrating learning while writing to learn, and writing to show learning often leads to new under- standings. In drafting, for example, you may start thinking about what an audience will need to know in order to under- stand your point and change a word or a phrase to make your meaning clearer. But understanding the differences between writing to learn and writing to show learning is central to seeing writing as a process.
What Doris Lessing said helps to support the idea that______.
A．he is one of the world' s great revisers
B．he is not a good writer
C．revising is very important
D．many writers are unwilling to revise their works

Pain is easier to endure if you know you can end it. Speakers at a session on pain at the British Association's psychology section have new evidence to support this idea for two common experiences of pain: in childbirth and at the dentist's. On the other side of the coin, their inability to control pain may explain why some people with continual pain have psychological problems as well.
Dr. J. Robinson found out about the phenomenon of self-controlled pain almost by accident. He was studying the effects of analgesics used to control pain during childbirth and as part of the experiment made it possible for women having their child to press a button which gave an automatic injection—instead of having all injections made by the doctor. Afterwards these women did not say that they had less pain than other women in childbirth, but they did use considerable less of the drug.
J. Atkins, a dental surgeon, has observed a similar phenomenon. As part of their efforts to make dentistry painless, Atkins and researchers at Aston University in Birmingham offered patients a switch they could flip to turn off the dentist's drill whenever they chose. But, after trying the switch on 50 patients Atkins gave up; none of the patients had ever flipped the switch.
Perhaps the extra endurance was because the Aston team also use other methods to make dentistry painless. Apparently few other dentists are so considerate. The end result, according to the Birmingham survey, is that British people avoid going to the dentist, with the consequence that almost 30% of people in England and Wales have lost all their teeth, and more than seven out of ten have lost at least six teeth. Less than half of the public pay regular visits to the dentist. To find out why, Atkins and psychologist Cumberbatch interviewed a sample of patients attending a dental hospital. The most common reason people gave for not having dental check-ups were fear and pain.
By using a little care and taking time to explain what will happen, Atkins feels, dentists could overcome these fears. There are techniques for giving injections without pain, and a "calm unhurried approach" to drilling can make that painless, too.
Sadly, few dentists seem to take much trouble with their patients. "I am not nervous when I go to the dentist, and I do not have any pronounced sympathy for those who are, " said one dentist. "I tend to take the point of view that they are being unreasonable at my expense."
The passage most possibly comes from______.
A．a medical textbook
B．a psychology textbook
C．a popular magazine
D．a serious magazine
