单选题The United Nations Population Fund has picked October 31 as the day the world will be home to 7 billion people. For better and worse, it"s a milestone. And there will be more milestones ahead. Fourteen years from now, there are expected to be 8 billion people on the planet. Most of the growth will occur in the world"s poorer countries. Proportionally, Europe"s population will decline, while Africa"s will increase. At around the same time, India will overtake China as the most populous nation on Earth. The growing global population is just one side of the coin. A recent report from the World Health Organization signaled the seriousness of the human population explosion: more than 3 billion people—about half the world"s population—are malnourished. Never before have so many, or such a large proportion, of the world"s people been malnourished. And in a growing number of countries, there is a seemingly unstoppable march toward sub-replacement fertility, whereby each new generation is less populous than the previous one, and population aging. As a result of declining fertility and increasing longevity, the populations of more and more countries are aging rapidly. Between 9,005 and 2050, a rise in the population aged 60 years or over will be visible, whereas the number of children (persons under age 15) will decline slightly. Population aging represents, in one sense, a success story for mankind, but it also poses profound challenges to public institutions that must adapt to a changing age structure. The latest national census in China shows the number of elderly people in the country has jumped to more than 13.3 percent of the population, an increase of nearly 3 percentage points on the percentage from the previous census in 2000. A quarter of the country"s population will be over 65 by 2050, according to the National Population and Family Planning Commission. The growing number of elderly is a challenge that the government needs to tackle, we can"t rely on the ever-increasing population to support them or maintain the nation"s economic growth. Better solutions are needed, such as raising retirement ages to reflect the greater longevity and working capability of today"s older adults and making adjustments so pension programs are more accessible. It was heartening to hear the Ministry of Human Resources and Social Security spokesperson announced in Beijing on Tuesday that the government will take the retirement policy seriously and proactively. Shanghai began testing a flexible retirement system last October. Eligible employees in the private sector are allowed to postpone retirement until the age of 65 for women. Public servants, however, will continue to retire under the present system—age 60 for men and 55 for women.

单选题Unlike the carefully weighed and planned compositions of Dante, Goethe's writings have always the sense of immediacy and enthusiasm. He was a constant experimenter with life, with ideas, and with forms of writing. For the same reason, his works seldom have the qualities of finish or formal beauty which distinguish the masterpieces of Dante and Virgil. He came to love the beauties of classicism, but these were never an essential part of his makeup. Instead, the urgency of the moment, the spirit of the thing, guided his pen. As a result, nearly all his works have serious flaws of structure, of inconsistencies, of excesses and redundancies and extraneities. In the large sense, Goethe represents the fullest development of the romanticist. It has been argued that he should not be so designated because he so clearly matured and outgrew the kind of romanticism exhibited by Wordsworth, Shelley, and Keats. Shelley and Keats died young; Wordsworth lived narrowly and abandoned his early attitudes. In contrast, Goethe lived abundantly anti developed his faith in the spirit, his understanding of nature and human nature, and his reliance on feelings as man's essential motivating force. The result was all-encompassing vision of reality and a philosophy of life broader and deeper than the partial visions and attitudes of other romanticists. Yet the spirit of youthfulness, the impatience with close reasoning or "logic-chopping," and the continued faith in nature remained his to tile end, together with an occasional waywardness and impulsiveness and a disregard of artistic or logical propriety which savor strongly of romantic individualism. Since so many twentieth century thoughts and attitudes are similarly based on the stimulus of the Romantic Movement, Goethe stands as particularly the poet of the modern man as Dante stood for medieval man and as Shakespeare for the man of the Renaissance.

单选题Building on the base of evidence and interpretation in Hansen's (1994) qualitative study of working people's diaries, we assigned each diarist a set of codes to indicate employment, marital status, number of children, and size of the town in which he or she lived. To analyze the number, location and gender mix of visiting occasions, we coded each day in January and July for every year of the diary, counting the number of named visitors, the visitors' gender, the size of the visiting occasion (1 to 4 people, or 5 and above), the gender mix of those present during the visit, and the location of the visit. While this may seem straightforward at first glance, the variable nature of the diary entries meant that the coding process was not as uncomplicated as we initially anticipated. Given the number of diarists and the span of diary-keeping years, we faced the possibility of coding over 200,000 diary days. Because of the labor-intensive nature of the coding and the number of entries, we chose to code only 2 months——January and July——of each year a diarist kept a diary. We chose 2 months that could reflect a range of sociability. Severe January weather in New England impeded mobility, but it also freed those who were farmers from most of their labor——intensive chores. July tended to be haying season for farmers, which meant some people routinely worked all month in the fields——some alone, some with hired help. Further, the clement July weather meant grater mobility for all of the diary keepers. For some people——those who kept a diary for only a single year——the fact that we coded only 2 months out of each year meant we have only 62 "diary-days" to document their social lives. For others, we have several thousand. Limiting ourselves to January and July for each diary year, we nonetheless coded entries for a total of 24,752 diary days. In an effort to capture an accurate picture of visiting patterns, we coded every day of a given month, even those that had no entry or that mentioned only the weather, as well as those that recorded numerous visiting occasions in one day. Determining a working definition of what constituted a visit was also an unexpected challenge. For example, although schoolteacher Mary Mudge kept a meticulous record of her visiting "rounds," listing names, places, and conversation topics, other diarists were not as forthcoming. A typical entry in farmer John Campbell's diary (9 July, 1825) was less amenable to our initial coding scheme: "Go to Cart's for Oxen." (See Hansen and Mcdonald, 1995, for a fuller discussion of the pitfalls of coding diary data.) We therefore created the following coding protocol. We defined a visit as any occasion in which the diarist names the presence of individuals not of his or her household, the presence of the non-household member serving to distinguish between a community interaction and a household interaction. We also coded as visits public events at which the diarist was present but others in attendance were not named. The most common among these were records of church attendance. Although an entry "went to church" did not result in a finding of specific male or female visitors, it was a community interaction; thus, these entries were coded as gender-mixed visiting occasions of five or more people in a public place. Because of the variable nature of diary-keeping practices, we were careful to record only what we could confidently infer. Therefore, some entries record visits but no named individuals. Others, such as church attendance (which is generally a large-group event) or a visit to one named friend (which is an intimate affair), allowed ns to code the size of the group. Still others, when the location of the visit was specifically mentioned, allowed us to code the diarist as hosting, acting as a guest in another's home, or interaction at a public place.
