2013届高考英语听力特训3（word文本）：23soviet officials have confirmed that a crippled nuclear submarine sank in the atlantic early today. us officials believe the sub carried at least sixteen nuclear missiles. explosion and fire on the vessel last friday killed three crewmen. the rest of the crew was successfully evacuated before the vessel sank. soviet officials say no radiation leaked in the air or the ocean. its unclear what may have caused the explosion that led to the sinking. a news agency in beirut released a videotape today with pleas from three frenchmen held for more than a year by the islamic jihad. each hostage called on the french government to change its policy in the middle east. melody walker reports from paris. during the twenty-eight-minute recording, the three hostages criticized the french government for failing to gain their release, and said they had the impression they were being forgotten. taking turns reading prepared texts, the two diplomats and one journalist looked physically exhausted and emaciated. declaring that he was at the end of his rope, one of the hostages said that the government forgot about the remaining hostages after the release of two frenchmen in june. a total of seven french citizens are currently held hostage in lebanon. a communiqu from the islamic jihad which accompanied the video cassette calls on france to negotiate the release of seventeen shiite prisoners jailed in kuwait. the french minister for foreign affairs did not comment on the content of the video cassette or the demands, but said tonight that the government was doing everything possible to free the hostages. for national public radio, this is melody walker in paris. skies are clearing over oklahoma where heavy rains have produced whats being called the worst flooding in the history of that state. thousands of people began returning to their homes and officials began the task of assessing the damage. floods have caused millions of dollars in damage, but specific estimates may not come until tomorrow when clean-up operations are expected to start. tonight, a soviet nuclear submarine is on the bottom of the atlantic ocean, damaged three days ago by a fire on board. officials in washington and moscow confirmed this mornings sinking. officials in both countries also said the loss of the vessel presents no atomic threat despite the presence of both nuclear missiles and a nuclear power reactor on the submarine. nprs daivd malthus has a report: pentagon officials say the crippled soviet submarine, which normally carries sixteen nuclear missiles, each with two warheads, went down just before dawn six hundred and eighty miles northeast of bermuda. the soviets put the precise time of sinking at 4:03 am eastern time, and moscow says there was no further loss of life aside from the three crewmen killed when a fire broke out friday. american surveillance planes observed that towing efforts were halted shortly after midnight. about three hours later, the remaining crew members were observed abandoning ship in an orderly and planned fashion, according to american officials. the crew was rescued from life rafts by five soviet surface ships in the area. pentagon officials say a us ocean-going tugboat was nearby and ready to assist, but the soviets refused any help. pentagon sources do not rule out the possibility that the soviets scuttled their sub once it became clear that leaks could not be controlled. the soviets have not explained the cause of the damage to the ship, but pentagon officials say there was an explosion in one of the missile tubes that blew a big hole in the deck. vice admiral powell carter describes the damage this way: youre talking about a structure thats enormously strong up there. its like, each of those missile tube doors that shuts is just like a safe vault. and then it shuts and locks with a big rotating ring, and thats been torn completely loose and bent like a pretzel back. so the force of the explosion was enormous. while pentagon officials say they dont know what caused the missile tube explosion, they point out that soviet missiles use highly volatile liquid fuel, and a fuel leak could have caused the eruption. again, admiral carter: these liquid fuel systems are very, very dangerous; theyre very unstable. thats why, very early in our missile program as pushing a leading edge of technology, we moved to solid fuel missiles, early on just for that fact, because liquid fuel is extremely dangerous. admiral carter said it was possible the nuclear warheads on top of the missile burned in the fire, or were thrown out into the water and sunk to the bottom 18,000 feet below. he said the other missiles and warheads might have been damaged by pressure as the sub sank, but there was no chance of a nuclear detonation or serious radiation leakage. the submarines nuclear reactors, officials say, are self-contained in what amounts to rust-proof metal vaults, and the soviet say the reactors were shut down prior to sinking. us officials say preliminary tests of the air and sea in the area have produced no signs of radioactive release. pentagon officials say the us will not make any attempt to recover the soviet sub. its soviet property, says the navy. retired submarine captain james bush of the center for defense information says a salvage effort just isnt warranted in this case with the submarine that was designed in the 1960s. its an old submarine with old missiles. i dont know that we would consider it worthwhile to have them to look at for the amount of money involved. now, it would probably be worthwhile if we could, get their communications equipment and their coding equipment, their key lists, and things like that to decode messages. but im sure that the soviets, with the time that they had prior to the submarine sinking, should have gotten all of that material off. pentagon officials say the sub loss should not be a serious setback for the soviets, but some analysts disagree. pentagon consultant norman freedman says the soviets have to be worried about liquid fueled missiles on other subs. these things are time bombs, freeman says. they should all be called in and checked out. im david malthus in washington. we think that we have solved this most venerable and grand of geographic mysteries. with those words, joseph judge of national geographic magazine announced a major discovery in american historythe true spot where christopher columbus first landed in the new world. and the geographic s declaration upsets the orthodox assertions of nearly every american history textbook. nprs frank browning has this story. the orthodox explanation of where columbus first landed was carved in textbook stone more than forty years ago by the dean of columbus historians, samuel elliot morrison. morrison declared incontrovertible the evidence that columbus first set foot on watling island in the eastern bahamas. but if the question were closed for professor morrison, now dead, it was not for numerous other students on nautical history. for the last five years, the national geographic s joseph judge, has dispatched teams of historians, oceanographers, archaeologists and translators to find the true location and thereby to set straight the first footsteps of the american saga. the famous fleet of columbusthe nina, the pinta and the santa mariamade its first landfall and its landing in the new world in 1492 at a small island in the eastern bahamas, named today, samana cay. the basic problem in identifying columbus landing point, which he named san salvador in 1492, is that he left no clear markings. moreover, the log of columbus voyage now exists only in a transcription made by the spaniard bartolomay de las casas, and many of the descriptions are either vague or use archaic terminology. professor morrison had based has conclusions on a straightforward reading of the log. but he took no account of how columbus route would have been affected by constant ocean currents and winds. when the geographic team took the same data and then adjusted them for the effect of wind and current, they arrived at samana cay, to the southeast of watling island. then to collaborate their findings, they went to points further down on columbus voyage, then backtracked according to the log notations, and again found that they landed not on professor morrisons watling island, but on samana cay. once on samana, the team then returned to columbus log, to compare what they saw to columbus ow
