Accompanied only by an Indian guide, the American explorer and a
13、rchaeologist Edward Herbert Thompson - thirteen hundred years after the Mayas had left their cities and made a break for the country farther north-was riding through the New Empire that they had built for themselves, which had collapsed after the arrival of the Spaniards. He was searching for Chiche
14、n-Itza, the largest, most beautiful, mightiest, and most splendid of all Mayan cities. Horses and men had been suffering intense hardships on the trail. Thompsons head sagged on his breast from fatigue, and each time his horse stumbled he all but fell out of the saddle. Suddenly his guide shouted to
15、 him. Thompson woke up with a start. He looked ahead and saw a fairyland.Above the dark treetops rose a mound, high and steep, and on top of the mound was a temple, bathed in cool moonlight. In the hush of the night it towered over the treetops like the Parthenon of some Mayan acropolis. It seemed t
16、o grow in size as they approached. The Indian guide dismounted, unsaddled his horse, and rolled out his blanket for the nights sleep. Thompson could not tear his fascinated gaze from the great structure. While the guide prepared his bed, he sprang from his horse and continued on foot. Steep stairs o
17、vergrown with grass and bushes, and in part fallen into ruins, led from the base of the mound up to the temple. Thompson was acquainted with this architectural from, which was obviously some kind of pyramid. He was familiar, too, with the function of pyramids as knows in Egypt. But this Mayan versio
18、n was not a tomb, like the Pyramids of Gizeh. Externally it rather brought to mind a ziggurat, but to a much greater degree than the Babylonian ziggurats it seemed to consist mostly of a stony fill providing support for the enormous stairs rising higher and higher, towards the gods of the sun and mo
19、on.Thompson climbed up the steps. He looked at the ornamentation, the rich reliefs. On top, almost 96 feet above the jungle, he surveyed the scene. He counted one - two - three - a half-dozen scattered buildings, halfhidden in shadow, often revealed by nothing more than a gleam of moonlight stone.Th
20、is, then, was Chichen-Itza. From its original status as advance outpost at the beginning of the great trek to the north, it had grown into a shining metropolis, the heart of the New Empire. Again and again during the next few days Thompson climbed on to the old ruins. “I stood upon the roof of this
21、temple one morning,“ he writes, “just as the first rays of the sun reddened the distant horizon. The morning stillness was profound. The noises of the night had ceased, and those of the day were not yet begun. An the sky above and the earth below seemed to be breathlessly waiting for something. Then
22、 the great round sun came up, flaming splendidly, and instantly the whole world sang and hummed. The birds in the trees and the insects on the ground sang a grand Te Deum. Nature herself taught primal man to be a sunworshipper and man in his heart of hearts still follows the ancient teaching.“Thomps
23、on stood where he was, immobile and enchanted. The jungle melted away before his gaze. Wide spaces opened up, processions crept up to the temple site, music sounded, palaces became filled with revelling, the temples hummed with religious adjuration. He tried to recognise detail in the billowing fore
24、st. Then suddenly he was no longer bemused. The curtain of fancy dropped with a crash; the vision of the past vanished. The archaeologist had recognised his task. For out there in the jungle green he could distinguish a narrow path, barely traced out in the weak light, a path that might lead to Chic
25、hen-ltzas most exciting mystery: the Sacred Well.（分数：4.00）(1).The territory which Thompson was exploring _.（分数：1.00）A.had been abandoned by the Mayas about thirteen hundred years previouslyB.had been occupied and developed by the Mayas about thirteen hundred years beforeC.had been deserted by the Ma

28、st magnificent of all phenomenaD.It is natural for man to worship the sun and he has always done so(4).What abruptly ended Thompsons dream of the past?（分数：1.00）A.The realization that this was only a time-consuming fantasy.B.The glimpse of an important clue to future discovery.C.A resolution derived
29、from his fantasy that he must learn more about this great past city.D.The locating of the mysterious Sacred Well.BTEXT B/BAs every ancient mariner knew, traveling by sail is a simple way to go. Though the winds could be fickle and the boats pokey, the energy source that moved the ship was free, plen
30、tiful and renewable. Now tile same technology that conquered the oceans of Earth may conquer the ocean of space.This week a Russian and American consortium will announce plans for an April launch of the first so-called solar-sail vehicle, a multicasted spacecraft that will use sunlight to push itsel
31、f along. To a public raised on smoke-and-fire rocketry, the idea of drawing energy straight from space seems fanciful. To the people behind the new ship, however, the technology is not only sensible but inevitable, the easiest way to reinvent the business of cosmic travel. “This allows us to use ver
32、y little fuel to fly very great distances,“ says Bud Schurmeier, a former NASA engineer and an adviser to the project. “It s an in- triguing concept.“The idea behind solar sailing is simple. Although light is made of massless particles called photons, such ephemeral things exert real pressure, espec
33、ially when they flow so close a source as the sun. Attach a sail of lightweight Mylar or other material to a spacecraft, set it up in the path of .that outrushing energy, and you ought to be able to move in almost any direction.NASA has a keen interest in solar sailing and had budgeted 5 million to
34、invest igate 17 possible missions. It may select one as early as next month. But while the space agency has been mulling plans, the people behind the new ship, dubbed Cosmos I, have been getting set to fly. The project is the brainchild of Russias Babakin Space Center, near Moscow, and the Planetary
35、 Society in Pasadena, Calif., a think tank founded in 1979 by astronomer Carl Sagan and others. The two groups had long been developing plans for a solar-sail mission but got the cash to make it happen only last year when Ann Druyan, Sagans widow and head of the Media Company Cosmos Studios, and Joe
36、 Firmage, the founder of US Web, threw their names and about 4 million behind the effort. “I had talked to people about solar sailing before, “says Lou Friedman, former engineer at the Jet Propulsion Laboratory in Pasadena and director of the Planetary Society,“ but between the Russians capabilities
37、 and Anns vision, I knew this one would click.“The spacecraft is a 3-ft. metal with eight 35-ft. metallic wings. Mylar petals sprout from it - though the prototype used in the April launch will have just two petals. Mounted atop a reconfigured Russian ICBM and launched from a sub in the B arents Sea
38、, the Cosmos I will fly to an altitude of 260 miles, where it will deploy the wings and float for a minute of so. If all goes well, the wings will then be jettisoned and the sphere aerobraked back to Earth, its bounce-down on Russian soil cushioned by air bags.By some measures, this cosmic lob shot
39、is not that impressive, but for solar-sail scientists, the engineering is everything. Few doubt that when sunlight strikes the wings, the spacecraft will accelerate; the key is building wings that can open and pivot, allowing the ship to tack into the solar stream. If this mission works, a more ambi
40、tious orbital flight, using the eight-paneled craft, is set for the end of the year. The space-craft could circle Earth for months, surfing the sun until designers shut it down. “There will be a grandeur to it, “says Druyan, “a 70-ft. sail that will be visible to the whole planet.“Grandeur aside, cr
41、itics wonder if solar sails have a future. The technique is problematic in Earth orbit, since the changing position of sun relative to the space-craft makes constant tacking necessary. Sailing is best used for as the crow- flies shots to neighboring planets. Even in these cases, progress can be slow
42、, since sunlight exerts, at most, 2 lbs. of pres- sure per square half-mile, requiring a year or more to rev a spacecraft to interplanetary speeds. Worse, beyond Jupiter, sunlight flickers out almost entirely; to go any farther would require energy beamen from Earth orbit, perhaps by giant laser how
43、itzers. “None of these things has been tested, “says Mel Monte-merlo, one of NASAs solar-sailing chiefs. “We have a long way to go.“Whether that will continue to seem such a long way may depend on the spring-time flight of Cosmos I. A successful mission has a way of making impossible technologies se
44、em possible - a big burden for a small rocket that will, for one day at least, carry the hopes of the world s space community.（分数：4.00）(1).What is the energy source of this so-called solar-sail vehicle?（分数：1.00）A.Sunlight.B.Nuclear.C.Wind.D.Electricity.(2).What does “brainchild“ in the paragrapth 4

47、s that can open and pivot.BTEXT C/BIn April 1995, a young Chinese chemistry student at Beijing University lay dying in a Beijing hospital. She was in a coma, and although her doctors had performed numerous tests, they could not discover what was killing her. In desperation, a student friend posted a
48、n SOS describing her symptoms to several medical bulletin boards and mailing lists on the Internet. Around the world, doctors who regularly checked these electronic bulletin boards and lists responded immediately.In Washington D. C. , Do, John Aldis, a physician with the U.S. Department of State, saw the message from China. Using the Internet, he forwarded the message to colleagues in America. Soon an international group of doctors joined the e- mail discussion. A diagnosis emerged - the woman might have been poi
