解答 BGEAD
71.B 考查上下文联系.根据前面的"It is more than 4,000 miles(6,400km) wide where Columbus crossed it"可知,这里是在描述海的宽度,所以接下来也是具体描述海有多宽.故选B.
72.G 考查上下文联系.根据前面的"One of the longest mountain ranges of the world rises from the floor of the Atlantic"可知,接下来要具体讲述这条山脉的走向以及地理位置.故选G.
73.E 考查上下文联系.根据"It is a current of warm water.Another is the Labrador Current-cold water coming down from the Arctic"可知,洋流影响着它们流经的陆地的气候.故选E.
74.A 考查上下文联系.根据"Storms sweep across it and pile up great waves.Icebergs float down from the far north across the paths of ships."可知,海面并不是一直安全平稳.故选A.
75.D 考查上下文联系.根据后面的"Airplanes fly from New York to London in only eight hours and from South America to Africa in four!"可知,这里要讲述的是各种交通根据穿过这片区域所需要的时间.故选D.
