The first navigational lights in the New World were probably lanterns hung at harbor entrances. The first lighthouse was put up by the Massachusetts Bay Colony in 1716 on Little Brewster Island at the entrance to Boston Harbor. Paid for and maintained by "light dues" levied (征收) on ships, the original beacon was blown up in 1776. Until then there were only a dozen or so true lighthouses in the colonies. Little over a century later, there were 700 lighthouses.
The first eight lighthouses erected on the West Coast in the 1850s featured the same basic New England design: a Cape Cod dwelling with the tower rising from the center or standing close by. In New England and elsewhere, though, lighthouses reflected a variety of architectural styles. Since most stations in the Northeast were set up on rocky eminences (高处), enormous towers were not the rule. Some were made of stone and brick, others of wood or metal. Some stood on pilings or stilts; some were fastened to rock with iron rods. Farther south, from Maryland through the Florida Keys, the coast was low and sandy. It was often necessary to build tall towers there—massive structures like the majestic lighthouse in Cape Hatteras, North Carolina, which was lit in 1870.190 feet high, it is the tallest brick lighthouse in the country.
Not withstanding differences in construction appearance, most lighthouses in America shared several features: a light, living quarters, and sometimes a bell (or, later, a foghorn). They also had something else in common: a keeper and usually the keeper"s family. The keeper"s essential task was trimming the lantern wick (灯芯) in order to maintain a steady, bright flame. The earliest keepers came from every walk of life, they were seamen, farmers, mechanics, rough mill hands and appointments were often handed out by local customs commissioners as political plums. After the administration of lighthouse was taken over in 1852 by the United States Lighthouse Board, and agency of the Treasury Department, the keeper corps gradually became highly professional.

【正确答案】
C
【答案解析】[解析] 从第二段第八句话,“...like the majestic lighthouse in Cape Hatteras...it is the tallest brick lighthouse in the country.”我们可以得知,1870年建于北卡罗来纳州Hatteras角的灯塔是美国最高的砖砌灯塔,高度为190英尺。所以,正确答案是C。

We can know from the passage that the coast of North Carolina is ______.
【正确答案】
C
【答案解析】[解析] 从第二段第七、八句话“Farther south, from Maryland through the Florida Keys,...it is the tallest brick lighthouse in the country.”可知,马里兰(Maryland)和佛罗里达海岸(the Florida Keys)相似,而马里兰(Maryland)和佛罗里达(the Florida Keys)海岸是low and sandy。所以,北卡罗来纳州也应是low and sandy。选项A rocky eminences指的是美国东北海岸,选项B、D根本没有提及。所以,正确条案是C。
