单选题{{B}}TEXT F{{/B}} Eight times within the past million years, something in the Earth's climatic equation has changed, allowing snow in the mountains and the northern latitudes to accumulate from one season to the next instead of melting away each time. The enormous ice sheets resulting from this continual buildup lasted tens of thousands of years until the end of each particular glacial cycle brought a warmer climate. Scientists speculated that these glacial cycles were ultimately driven by astronomical factors: slow cyclic changes in the eccentricity of the Earth's orbit and in the tilt and orientation of its spin axis. But up until around 30 years ago, the lack of an independent record of ice age timing made the hypothesis untestable. Then in the early 1950s Emiliani produced the first complete record of the waxings and wanings of past glaciations. It came from a seemingly odd place. The seafloor single-cell marine organisms called "foraminifera" house themselves in shells made from calcium carbonate. When the foraminifera die, sink to the bottom, and become part of seafloor sediments, the carbonate of their shells preserves certain characteristics of the seawater they inhabited. In particular, the ratio of a heavy isotope of oxygen (oxygen-18) to ordinary oxygen (oxygen-16) in the carbonate preserves the ratio of the two oxygens in water molecules. It is now understood that the ratio of oxygen isotopes in seawater closely reflects the proportion of the world's water locked up in glaciers and ice sheets. A kind of meteorological distillation accounts for the link. Water molecules containing the heavier isotope tend to condense and fall as precipitation slightly sooner than molecules containing the lighter isotope. Hence, as water vapor evaporated from warm oceans moves away from its source, its oxygen-18 returns more quickly to the oceans than does its oxygen-16. What falls as snow on distant ice sheets and mountain glaciers is relatively depleted of oxygen-18. As the oxygen-18-poor ice builds up the oceans become relatively enriched in the isotope. The larger the ice sheets grow, the higher the proportion of oxygen-I 8 becomes in seawater—and hence in the sediments. Analyzing cores drilled from seafloor sediments, Emiliani found that the isotopic ratio rose and fell in rough accord with the Earth's astronomical cycles. Since that pioneering observation, oxygen-isotope measurements have been made on hundreds of cores. A chronology for the combined record enables scientists to show that the record contains the very same periodicities as the orbital processes. Over the past 800,000 years, the global ice volume has peaked every 100,000 years, matching the period of the orbital eccentricity variation. In addition, "wrinkles" superposed on each cycle-small-decrease or surge in ice volume have come at intervals of roughly 23,000 and 41, 000 years, in keeping with the precession and tilt frequencies of the Earth's spin axis.

单选题Such joy, It was the spring of 1985, and President Reagan had just given Mother Teresa the Medal of Freedom in a Rose Garden ceremony. As she left, she walked down the corridor between the Oval Office and the West Wing drive, and there she was, turning my way. What a sight: a saint in a sari coming down the White House hall. As she came nearer, I could not help it: I bowed. "Mother", I said, "I just want to touch your hand." She looked up at me -- it may have been one of Gods subtle jokes that his exalted child spent her life looking up to everyone else -- and said only two words. Later I would realize that they were the message of her mission. "Luff Gott," she said. Love God. She pressed into my hand a poem she had written, as she glided away in a swoosh of habit. I took the poem from its frame the day she died. It is free verse, 79 lines, and is called "Mothers Mediation (in the Hospital)." In it she reflects on Christ's question to his apostles: "Who do you say I am?" She notes that he was the boy born in Bethlehem, "put in the manager full of straw.., kept warm by the breath of the donkey," who grew up to be "an ordinary man without much learning." Donkeys are not noble; straw is common; and it was among the ordinary and ignoble, the poor and sick, that she chose to labor. Her mission was for them and among them, and you have to be a pretty tough character to organize a little universe that exists to help people other people aren't interested in helping. That's how she struck me when I met her as I watched her life. She was tough. There was the worn and weathered face, the abrupt and definite speech. We think saints are great organizers, great operators, and great combatants in the world. Once I saw her in a breathtaking act of courage. She was speaker at the National Prayer Breakfast in Washington in 1995. All the Washington Establishment was there, plus a few thousand born-again Christians, orthodox Catholics and Jews, and searchers looking for a faith. Mother Teresa was introduced, and she spoke of God, of love, of families. She said we must love one another and care for one another. There were great purrs of agreement. But as the speech continued it became more pointed, She asked, "Do you do enough to make sure your parents, in the old people's homes, feel your love? D9 you bring then each day your joy and caring?,' The baby boomers in the audience began to shift in their seats. And she continued. "I feel that the greatest destroyer of peace today is abortion," she said, and then she told them why, in uncompromising term. For about 1.3 seconds there was complete silence, then applause built and Mrs. Gore, looked like seated statues at Madame Tussauds, glistening in the lights and moving not a muscle. She didn't stop there either, but went on to explain why artificial birth control is bad and why protestants who separate faith from works are making a mistake. When she was finished, there was almost no one she hadn't offended. A U.S. Senator turned to his wife and said, "Is my jaw up yet?" Talk about speaking troth to power! But Mother Teresa didn't care, and she wasn't afraid. The poem she gave me included her personal answers to Christ's question. She said he is "the Truth to be told.., the Way to be walked... the Light to be lit." She took her own advice and lived a whole life that showed it.

单选题More than just a revolutionary tool for indexing, analyzing, or transmitting content, digital technology is actually reshaping the creation of art and literature. "Just as film emerged as the dominant artistic medium of the 20th century, the digital domain -- whether it is used for visual art, music, literature or some other expressive genre -- will be the primary medium of the 21st," wrote New York Times columnist Matthew Mirapaul in early 1999. More and more writers, artists, and musicians are using computers and the Internet to enhance, animate, or completely remake their art, with unconventional and remarkable results. Publishing, a print-based business that to some people is beginning to represent the past, is attempting to adapt to the new digital world. Marc Aronson, a senior children's book editor at the publishing house Henry Holt and a longtime student of the impact of changing technology on publishing, describes this impact as a kind of blurring or hybridization. "The keynote of the digital age is overlap, multiplicity, synergy. The digital does not replace print, it subsumes it," Aronson said. "Print becomes a form of the digital, just as the digital has a special place when it appears in print." Especially in books for young people, he notes, more authors and artists are trying books with multiple story lines or told from various points of view. One strain of this new type of nonlinear writing is popularly known as hypertext fiction. At its simplest, hypertext fiction mimics the Choose Your Own Adventure books that became popular in the early 1980s. In these books, readers directed the story by choosing which page to turn to at key points based on what they wanted the character to do. In hypertext fiction, the reader explores different branches of a story on a computer by clicking on hyperlinks in the text. The result is a fragmented, slightly surreal narrative in which time is not linear and there is no obvious conclusion. Michael Joyce, a professor of English at Vassar, is a leading theoretician and author of hypertext fiction. He wrote what is widely considered the first major work of hypertext fiction, afternoon, a story (1990). The piece consists of more than 500 different screens, or pages, which are connected by more than 900 links, afternoon centers on a man who witnesses a serious car accident that may or may not have involved his ex-wife and son, who may or may not have survived. Joyce has also published Twilight, A Symphony (1996), about a man estranged from his wife who is on the run with their infant son. Joyce defines hypertext fiction as "stories that change each time you read them." He notes that "interactive narrative does not necessarily mean multiple plot lines, but can also mean exploring the multiple thematic lines or contours of a story." Not surprisingly, hypertext has frequently come under attack from traditional critics. Perhaps the most powerfully simple critique, however, comes from Charles Platt, a contributing editor for Wired magazine and a prominent science-fiction writer and critic. "Could it be," wonders Platt, "that storytelling really doesn't work very well if the user can interfere with it?" People really want the author, scriptwriter, or actors to do the heavy lifting of narrative, he argues. On the other hand, Platt suspects that we have hardly begun to explore true interactive media and that it will be utterly different from fiction as we know it today.
