In 1958, the Navy's nuclear-powered submarine Nautilus surfaced in the Greenland Sea after a 1,830 mile journey, under the polar ice pack, from the Pacific to the Atlantic Ocean. A number of surface ships had sailed between those oceans, either via the Northwest Passage, close to the islands of the Canadian Arctic, or via the Northeast Pas-sage, along the northern coasts of Europe and Asia, the Nautilus, however, was the first ship to go from ocean to ocean via the North Pole.
The Nautilus, in 96 hours, sailed an almost direct course under the ice, traveling a greater part of the way at a depth of 400 feet and a speed of 20 knots. The submarine was well below the ice, which in general is only from 7 to 14 feet thick, though stalactites (似钟乳石状的冰) sometimes reach depths of 125 feet.
This voyage effectively brought to the world's attention the potential role of nuclear-powered submarines, capable of sailing beneath the polar pack and launching missiles from any of the countless lagoons (礁湖) and channels of open water that divide it.
The submarine also seems to have been designed to offset the effect of the Soviet satellite on world opinion. Although the Nautilus did not come back empty-handed from the scientific point of view, the voyage was as much a demonstration of potential as it was a scientific expedition. Undoubtedly, much more was learned about the polar pack by those aboard the two American and two Soviet ice-borne, scientific stations then adrift in the Arctic Ocean than by the group that manned the Nautilus.
11. The unusual feature of this inter-ocean voyage was that the Nautilus ______.
A) sailed to the Greenland Sea B) journeyed under the ic~pack
C) traveled thousands of miles D) traveled from the Pacific to the Atlantic Ocean
12. The journey of the Nautilus ______.
A) had no military significance
B) proved to the world' the capability of nuclear-powered submarines to navigate in polar waters
C) proved that atomic-powered submarines cannot be used to launch missiles
D) was little noted by the rest of the world
13. The author suggests that the journey of the Nautilus was intended ______.
A) to prove the feasibility of launching a moon satellite from the Greenland Sea
B) as-propaganda('~) to offset the success of the Russian satellites
C) to offset the success of a Russian nuclear-powered submarine
D) to discover Russian missile sites in Siberia
14. According to the author, the voyage of the Nautilus was, from the scientific point of view, _____.
A) more a demonstration of potential than a scientific expedition
B) more an expedition than a demonstration
C) a complete failure D) a magnificent success
15. At the time of the voyage of the Nautilus ______.
A) the polar ice pack was completely uninhabited B) American scientists were studying the ice pack
C) Russian scientists were studying the ice pack D) both B and C

Answer 1

1958年,美国海军的一艘核动力潜艇浮出格陵兰岛海鹦鹉螺后,1,830英里的旅程在极地冰包,从太平洋和大西洋。大量的船只航行了两者之间的海洋,或者通过西北通道,靠近加拿大北极的岛屿,或者通过东北Pas-sage沿北部海岸,欧洲和亚洲,鹦鹉螺,但第一艘船在海洋之间经由北极。
鹦鹉螺,于96小时航行,几乎直接课程冰层之下,大部分的旅行方式,深度为400英尺的速度是20海里。海底是远低于一般的冰,只有从七岁到14英尺厚的,虽然有时达到(似钟乳石状的冰钟乳石相接的125英尺的深度。
这个旅行有效带到世界瞩目的潜在作用,能够对核动力潜艇航行在极地包装和发射导弹,从任何的无数潟湖)和通道(礁湖开的水,把它。
潜水艇也似乎是为了弥补这个效果在世界舆论苏联卫星。虽然鹦鹉螺没回来空手而归从科学的角度来看,这次航程一样的潜力是示范一次科学考察。毫无疑问,更多的是了解极地的包裹登上两名美国人,两个前苏联ice-borne、科学考察站然后漂泊在北冰洋上的,而不是由集团载人鹦鹉螺。（我帮你翻译好你自己做吧）
