In the 18th century, New York was smaller than Philadephia and Boston. Today it is the largest city in AmericA.How to explain the change in its size and importance?To answer this question we must consider certain facts about geography, history and economies. Together these three will explain the huge growth of America's most famous city.The map of the Northeast shows that four of the most heavily-populated areas in this region are around seaports. At these points materials from across the sea enter America, and the products of the land are sent there for export across the seA.Economists know that places where transportation lines meet are good places for making raw materials into completed goods. That is why seaports often have cities nearby. But cities like New York needed more than their geographical location in order to become great industrial centers. Their development did not happen simply by chancE.About 1815,when many Americans from the east coast had already moved to the west, trade routes from the ports to the central regions of the country began to be a serious problem. The slow wagons of that time, drawn by horses or oxen, were too expensive for moving heavy freight very far. Americans had long admired Europe's canals. In New York State a canal seemed the best solution to the transportation problem. From the eastern end of Lake Erie all the way across the state to the Hudson River there is a long trip of low lanD.Here the Erie Canal was constructeD.After working for several years it was completed in 1825.The canal produced an immediate effect. Freight costs were cut to about one-tenth of what they had been. New York City, which had been smaller than Philadelphia and Boston, quickly became the leading city of the coast. In later years, transportation routes on the Great Lakes were joined to mutes on the Mississippi River. Then New York City became the end point of a great inland shipping system that extended from the Atlantic Ocean far up the western branches of the ississippi.The new railroads made canal shipping not important as before, but it tied New York even more closely to the central regions of the country. It was easier for people in the central states to ship their goods to New York for export overseas.Exports from New York were greater than imports. Consequently, shipping companies were eager to fill their ships with passengers on the return trip from EuropE.Passengers could come from Europe very cheaply as a result.Thus New York became the greatest port for receiving people from European countries. Many of them remained in the city. Others stayed in New York for a few weeks, months, or years, and then moved to other parts of the United States. For these great numbers of new Americans, New York had to provide homes, goods, and services. Their labor helped the city become great.Which of the following can be the best title for the passage?A.The Development of Transportation in New York.B.Exports and Imports of New York.C.How New York Became America's Largest City?D.How New York Exchanged with Europe?

In an interview last month, Frank Church, chairman of the Senate committee which is investigating the CIA, issued an oblique but impassioned warning, that the technology of eavesdropping had become so highly developed that Americans might soon be left with 'no place to hide'. That day may have arriveD.Newsweek has learned that the country's most secret intelligence operation, the National Security Agency, already possesses the computerized equipment to monitor nearly all overseas telephone calls and most domestic and international printed messages.The agency's devices monitor a great deal of telephone circuits, cable lines and the microwave transmissions that carry an increasing share of both spoken and written communications. Computers are programed to watch for 'trigger' words or phrases indicating that a message might interest intelligence analysis, when the trigger is pulled, entire messages are tape-recorded or printed out.That kind of eavesdropping is, however, relatively simple compared with the breakthroughs that lie ahead in the field of snoopery. Already it is technically feasible to 'bug' an electric typewriter by picking up its feeble electronic emissions from a remote location and then change them into words. And some scientists believe that it may be possible in the future for remote electronic equipment to interceptand 'read' human brain waves.Where such capabilities exist, so too does the potential for abusE.It is the old story of technology rushing forward with some new wonder, before the man who supposedly control the machines have found how to prevent the machines from controlling them.Which is the best title for the passage?A.Fight Against Eavesdropping.B.A New Breakthrouth.C.No Place to HidE.D.An Impassioned Warning.
