The First Navigational LightsIn the New World the first navigational lights were probably

The First Navigational Lights

In the New World the first navigational lights 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 on ships, the original beacon was blown up in 1776. By then there were only a dozen of 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 1850's 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 built on rocky eminences, 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 Cape Hatteras, North Carolina lighthouse, which was lit in 1870. At 190 feet, is the tallest brick lighthouse in the country.

Notwithstanding differences in appearance and construction, most American lighthouses shared several features: a light, living quarters and sometimes a bell (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 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 lighthouses was taken over in 1852 by the United States Lighthouse Board, an agency of the Treasury Department, the keeper gradually became highly professional.

What is the best title for this passage?

A.The Life of a Lighthouse Keeper

B.The Modern Profession of Lighthouse Keeping

C.Early Lighthouse in the Unites States

D.The Lighthouse on Little Brewster Island

By the first century A.D, historians say, the Chinese had some knowledge of the winds and
currents of the Pacific. When weather prevented the Chinese from navigating by the sky their mariners(水手) used magnetized(磁化) needles to guide them. Because the sailors had no level surface on their rocking ship, they floated the needle in a shallow bowl of water, and the compass that guided explorers to day was born.

Between 1450 and 1433, Emperor Chu Ti's Treasure Fleet of the Dragon Throne ruled the entire south Pacific and the Indian Ocean, collecting gifts and tributes(贡品) for the Emperor throughout a territory that ranges from Korea and Japan to Eastern coast of Africa. The Admiral Cheng Ho began the first of seven voyages in 1405. The purpose of the first voyage was to hurt the former emperor who had been dethroned and escaped. The admiral's fleet, which was made up of 62 large junks and 255 smaller ships, recaptured the deposed emperor and also defeated a large pirate fleet that had been terrorizing the islands near Sumatra. Over the next 28 years, Admiral Cheng Ho increased China's trading territory to including 37 countries from the Vietnam coast to Persian Gulf, the Red Sea, and eastern Africa. Cheng He's death around 1435 signaled the end of the Treasure Fleet and disappearing of China's economic domination of the South Pacific.

It is implied but not stated that ancient navigation used to sail ______.

A.with their knowledge of the winds

B.by the sky

C.by the compass

D.by the currents of the Pacific

How can science be encouraged to flourish and grow? How can the results of science be used
to the best purpose for the benefit of humanity? 71. It was to find the answers to these question% which are not merely academic but practical ones, that this whole inquiry into the place of science in society was undertaken. It can be justified only in so far as it helps to find them.

The way to answer the first question is to find the best conditions, external and internal, which have in the past helped the progress of science and to anticipate the changed needs of the present and future. The answer to the second question, which depends on the first, is set out towards the end of this chapter. Some of the external conditions for the flourishing of science in the past have already been discussed. 72. In essence they are provided only in periods of social and economic advance, when science is given social importance and material means and is continually stimulated to new activity by problems presented to it from the economic and social spheres.

73. Now these problems have been essentially, as we have seen, those that touched the interests of the ruling class of the time, whether real, like navigation, or imaginary, like astrology. The opportunity and the honor given to the practitioners of science at any time are a measure of the degree to which they serve at these interests. They are greatest in periods of active advance, because then the people who are occupied with science are closely in touch with the main economic interests, and are often drawn from the directing classes themselves or are brought into their counsels because of their abilities. We have had many examples in these pages such as: Archimedes, Grosseteste, Leonardo, Galileo, Boyle, Davy, Pasteur, Kelvin.
