问题     The first navigational lights in the New World were probably lighthouses 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. Litde 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.
Which is the best title for the passage?
选项 A、The Lighthouse on Litde Brewster Island.
B、The Life of a Lighthouse Keeper.
C、Early Lighthouses in the United States.
D、The Modern Profession of Lighthouse-keeping.
答案C
解析 本文从最早美国灯塔的雏形，谈到美国早期灯塔的建筑，以及美国早期灯塔在外形和建筑上的共同点，最后还谈到了灯塔管理人员的工作生活。文章所提到的要点都是围绕着美国早期灯塔。选项B、D文中均有涉及，但并非重点。A项只提到了美国第一座灯塔。所以，正确答案是C。
