Article: For the first time in modem history, less than half of theprefix = st1 /U.S.adult population now reads literature, according to a recent survey. Reading at Risk: A Survey of Literary Reading inAmericapresents a detailed review of the decline of reading's role in the nation's culture. Readingat Risk is a survey of national fashion in adult literary reading. The data source for Reading at Risk is as reliable and objective as any such survey can be. The key results of the survey are presented in the "Summary", but the report can be further explained as: literary reading in Americais not only declining rapidly among all groups, but the rate of decline has been speeded up, especially among the young.Readingat Risk merely shows a great _ that most Americans have already noted - our society's great turn to electronic media for entertainment and information. Reading a book requires a degree of active attention and devotion. Indeed, reading itself is a progressive skill that depends on years of education and practice. On the contrary, most electronic media such as television, recordings, and radio make fewer demands on their audiences, and indeed often require no more than passive participation. While oral culture has a rich reality and electronic media offer the considerable advantages of variety, print culture affords irreplaceable forms of focused attention and thought that make various communications and views possible. The decline in reading, therefore, equals a larger retreat from participation in public and cultural life. What is to be done? There is surely no single solution to the present problem, just as there is no single cause. The important thing now is to understand thatAmericacan no longer take active and devoted reading for granted. Readingis not a timeless, common ability. As more Americans lose this ability, our nation becomes less informed, active, and independent minded. These are not qualities that a free, inventive, or productive society can afford to lose.

Article: What is politeness? This sounds like a simple question. In daily life, we often make judgments about what is polite and what is not polite. For example, to offer your seat to the elderly on a bus is considered polite behavior, and to interrupt when someone is talking is considered impolite; to greet someone the first time you meet him in the morning is polite and to stand up to reach for the dish you want at a dinner table is impolite. So politeness can first of all be regarded as a phenomenon, an observable social phenomenon. What I would like to propose is that as an observable social phenomenon, politeness is something superficial, but to account for what is understood at the surface, we should dig into the depth where different cultural values are rooted. When being complimented , an English-speaking person would readily accept the compliment by saying something like "Thank you" to show his appreciation of the praise, but a Chinese speaker would try to deny the truth of the compliment. They both think they are behaving properly. Yet neither of them would think the other is being polite. The English speaker is being polite to the extent that by accepting and showing appreciation of the compliment, and he avoids hurting the positive face of the person who makes it; the Chinese speaker is showing modesty by _ himself, ignoring the fact of the compliment paid to him. As has been mentioned, self-denigration has been at the core of the Chinese understanding of politeness for over two thousand years. The Chinese, in order to show modesty, will go to such lengths as to underrate what he himself has achieved and deny the truth of a complimentary remark.

Article: In the Caucasus region of Russia, nearly 50 out of every 100,000 people live to celebrate their 100th birthday, and many don't stop at 100! By comparison, in America only 3 people in 100,000 reach 100. But these Russian old people aren't alone. The Pakistanis, who live high in the Himalaya Mountains, and the Ecuadorans of the Andes Mountains seem to share the secret of long life, too. These people remain healthy in body and spirit despite the passage of time. While many older persons in industrial societies become weak and ill in their 60s and 70s, some Caucasians aged 100 to 140, work in the fields beside their great-great-grandchildren. Even the idea of aging is foreign to them. When asked "at what age does youth end?"most of these old people had no answer. Several replied, "Well, perhaps at age 80." What accounts for this ability to survive to such old age, and to survive so well?First of all, hard physical work is a way of life for all of these long-lived people. They begin their long days of physical labor as children and never seem to stop. For example, Mr . Rustam Mamedov is 142 years of age. His wife is 116 years old. They have been married for 90 years. Mr. Mamedov has no intention of retiring from his life as a farmer. "Why?What else would I do?"he asks. All these people get healthful rewards from the environment in which they work. They all come from mountainous regions. They live and work at elevations of 1,660 to 1,000 meters above sea level. The air has less oxygen and is pollution-free. This reduced-oxygen environment makes the heart and blood vessel system stronger. Another factor that may contribute to the good health of these people is their isolation. To a great extent, they are separated from the pressures and worries of industrial society. Inherited factors also play some role. Most of the longest-lived people had parents and grandparents who also reached very old ages. Good family genes may, therefore, be one factor in living longer.
Answer: are still working in the fields

Ex Output:
The example of Mr. and Mrs. Mamedov implies that some Caucasians aged 100 to 140 _ .
