| 第1题：{{B}}Passage Three{{/B}} The sensitivity of ice and snow to temperature changes is an early indicator of even relatively small differences, says University ofColorado atBoulder senior researcher RichardArmstrong. He has found that today’s receding and thinning sea ice, mountain glacier mass losses, decreasing snow extent, melting permafrost (永久冻土), and rising sea level are all consistent with warming. Global mean temperatures have risen one degree Fahrenheit over the past 100 years, with more than half of the increase occurring in the last 25 years, observesArmstrong who is affiliated with the National Snow and IceDataCenter headquartered atCU-Boulder. "As slight as that may seem, it’s enough to make a difference," saidArmstrong. "Now, long-term monitoring of a series of cold region, or cryospheric, parameters (参数) shows that for several decades the amounts of snow and ice around the world have been decreasing. " The extent ofArctic sea ice is shrinking by about 3 percent per decade, but the trends are not uniform. While recent studies have indicated that the ice thickness also had decreased over several decades, new information shows that the ice may have thinned rapidly,Armstrong saiD、Examination of springtime ice thickness in theArctic Ocean indicates that the mean ice thickness decreased 1.5 meters (4. 8 feet) between the mid-1980s and early 1990s. To mark its 25th anniversary, the National Snow and IceDataCenter has organized a special session at the 2001 Fall Meeting ofAmerican Geophysical Union, taking place this week in San Francisco, that illuminates overall changes in the cryosphere. The session begins Tuesday and extends through Thursday afternoon, with 75 contributions from all areas of cryospheric study. Papers and posters include examinations of lake and river ice, glacier dynamics, and mass ice balance studies in polar and continental glaciers, regional and polar snow cover trends, and variations inCanadian ice cap elevations. |

| 第3题： A、good modern newspaper is an extraordinary piece of reading. It is remarkable first for what it contains the range of news from local crime to international politics, from sports to business to fashion to science, and the range of comment and special features (特定) as well, from editorial page to feature articles and interviews to criticism of books, art, theatre and musiC、 A、newspaper is even more remarkable for the way one reads it never completely, never straight through, but always by jumping from here to there, in and out glancing at one piece, reading another article all the way through, reading just a few paragraphs of the next. A、good modern newspaper offers a variety to attract many different readers, but far more than any one reader is interested in. What brings this variety together in one place is its topicality (时事性), its immediate relation to what is happening in your world and your locality now.But immediacy and the speed of production that goes with it mean also that much of what appears in a newspaper has no more than transient (短暂的) value. For all these reasons, no two people really read the same paper: what each person does is to put together out of the pages of that day’s paper, his own selection and sequence, his own news paper. For all these reasons, reading newspapers efficiently, which means getting what you want from them without missing things you need but without wasting time, demands skill and self-awareness as you modify and apply the techniques of reading. A、modem newspaper is remarkable for all the following except its ______. A、wide coverage B、uniform style C、speed in reporting news D、popularity |

| 第4题：Don’t have time to read anymore Now you can get free, quick literature via email. More than 100,000 people open their email each day to read a chapter of a book, throughChapter-A-Day, an online book club created two years ago. It’s a free email service that provides a short daily reading for busy people, exposing them to literature they may not find on their own, inspiring some to recommit to the reading habit.About 550 public library systems representing over 3,000 branch libraries already have signed up to offerChapter-A-Day. Via email, participants get about five minutes’ worth of reading every day.After three chapters are emailed, the installments stop, and those who want to keep reading can borrow the book at their public library or purchase it online.Chapter-A-Day has eight free book clubs, and sells thousands of books each month. Chapter-A-Day started in 1999 when SuzanneBeecher, a lifelong book lover, realized how many of the women who worked part-time for her software development company didn’t have time in their busy lives to reaD、She decided to type part of a chapter of a book, and send it to her employees through email. The next day she typed a little more, and continued to send literary installments each day. She says she started getting feedback from the staff about how reading made them feel. "They were interested, and realized that, though they didn’t have time in their busy lives for reading, just reading that little bit each day got them back in the habit." Realizing that many other people could benefit, she decided to take the idea even further and start an email "chapter-a-day" book club to help others ease their way back into daily reading. "Reading makes changes in people’s lives,"Beecher says. PatDempsey, a librarian at a public library in Ohio, has foundChapter-A-Day helps her library clients get back in the habit of reading. "It’s a different way to get people hooked on hooks," she says. The word "installment" in the passage probably means" ______ ". A、a library email B、a rare piece of literature C、a free novel D、a part of a book |

| 第5题：{{B}}Passage Three{{/B}} Although their missions blended commercial and political military imperatives, the explorers involved all accomplished some significant science simply by going where no scientists had gone before. Today Mars looms (隐约出现) as humanity’s next great terra incognita (未探明之地).And with growing emphasis on international cooperation in large space ventures, it is clear that imperatives (需要，必要) other than profits or nationalism will have to compel human beings to leave their tracks on the planet’s reddish surface.Could it be that science, which has long played a minor role in exploration, is at last destined to take a leading role The question naturally invites a couple of others:Are there experiments that only humans could do on MarsCould those experiments provide insights profound enough to justify the expense of sending people across inter- planetary space With Mars the scientific stakes are arguably higher than they have ever been. The issue of whether life ever existed on the planet, and whether it persists to this day, has been highlighted by mounting evidence that the Red Planet once had abundant stable, liquid water and by the continuing controversy over suggestions that bacterial fossils rode toEarth on a meteorite (陨石) from Mars.A、more conclusive answer about life on Mars, past or present, would give researchers invaluable data about the range of conditions under which a planet can generate the complex chemistry that leads to life. If it could be established that life arose independently on Mars andEarth, the finding would provide the first concrete clues in one of the deepest mysteries in all of science: the prevalence of life in the universe. |
