In the old days, children were familiar with birth and death as part of life. This is perhaps the first generation of American youngster(年轻人)who have never been close by during the birth of a baby and have never experienced the death of a family member.
Nowadays when people grow old, we often send them to nursing homes. When they get sick, we transfer them to a hospital, where children are forbidden to visit terminally ill patients--even when those patients are their parents. This deprives(剥夺)the dying patient of significant family members during the last few days of his life and it deprives the children of an experience of death, which is an important learning experience.
Some of my colleagues and I once interviewed and followed approximately 500 terminally ill patients in order to find out what they could teach us and how we could be of more benefit, not just to them but to the members of their families as well. We were most impressed by the fact that even those patients who were not told of their serious illness were quite aware of its potential outcome.
It is important for family members, and doctors and nurses to understand these patients' communications in order to truly understand their needs, fears, and fantasies(幻想). Most of our patients welcomed another human being with whom they could talk openly, honestly, and frankly about their trouble. Many of them shared with us their tremendous need to be informed, to be kept up-to-date on their medical condition, and to be told when the end was near. We found out that patients who had been dealt with openly and frankly were better able to cope with the approach of death and finally to reach a true stage of acceptance prior to death.
Five hundred critically ill patients were investigated with the main purpose of ______.
A．learning how to best help them and their families
B．observing how they reacted to the crisis of death
C．helping them and their families overcome the fear of death
D．finding out their attitude towards the approach of death

Parks contribute to the quality of the urban environment. Fortunately it is no longer necessary that every lecture or every book about this subject has to start with the proof of this idea. (111) At present it is generally accepted, although more as a self-evident statement than on the basis of a closely-reasoned scientific proof. The recognition of the importance of greenery in the urban environment is a first step on the right way. (112) This does not mean, however, that sufficient details are known about the functions of greenery in towns and about the way in which the inhabitants are using these spaces.As to this rather complex subject I shall, within the scope of this lecture, enter into one aspect only, namely the recreative function of parks.
(113) The theoretical separation of living, working traffic and recreation which for many years has been used in town-and-country planning, has in my opinion resulted in disproportionate attention for forms of recreation far from home, whereas there has been relatively little attention for improvement of recreative possibilities in the direct neighborhood of the home. (114) We have come to the conclusion that this is not right, because an important part of the time which we do not pass in sleeping or working is used for activities at and around home. So it is obvious that recreation in the open air has to begin at the front door of the house.
(115) The urban environment has to offer as many recreation activities as possible, and the design of these has to be such that more obligatory activities can also have a recreative aspect. The very best standard of living is nothing if it is not possible to take a pleasant walk in the district; if the children cannot be allowed to play in the streets, because the risks of traffic are too great; if during shopping you can nowhere find a spot for enjoying for a moment the nice weather; in short, if you only feel yourself at home after the front door of your house is closed behind you.

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
