The thing that is surprising about Tower Bridge is that it is open in the middle. It does this to let the big ships through to the Pool of London. If you are lucky enough to see the bridge with its two opening arms high in the air, you will never forget it.
On its north side stands the Tower of London itself. Although they look the same age, the Tower is almost a thousand years old, and Tower Bridge is only about one hundred, it was built in the 1890s. By1850, everyone agreed that a bridge across the Thames near the Tower was most necessary. But the designers argued about the new bridge for another thirtyyears. This took so long because they had two big problems.

Steel lightly covered with concrete is the main structural component of the towers and steel loses a lot of structural strength when heated to 1,100 degrees Centigrade and beyond, as it was. To shield the steel the towers beams(柱梁) were c0ated with a few centimeters of concrete. That insulation was to provide structural integrity for at least 1 hour of fire. The towers met that test. The south tower lasted 62 minutes. The north, 103 minutes. Tragedy followed when not all could escape prior to the collapse.
Most experts agree that the Twin Towers were very. well designed. Many also agree that the pan pie planning the attacks were very knowledgeable and aimed the aircraft at a height that would effect the most damage. The aircraft crash and the resulting fuel fed fires were aimed at about the 90th floor. That was just high enough to insure that the upper floors would weaken with the heat and crack down, dropping into the remaining part of the building. The mass of the falling top floors created such a falling load that some experts estimate it exceeded by 5 to 10 times normal bearing loads. The effect was like a giant hammer, each floor contributing more weight to be born by the next floor down.
Were the Trade Towers well designed？ Engineers say yes. But, the public refers to the belief that architects will never again design a tall building without considering the effects of terrorist attacks of all potential kinds. That not only includes the ability of the structure to withstand attack but the means to allow the buildings occupants(居住者) to escape in time to survive.
According to the article, those who designed the tower could have done better if ______.
A．the tower lasted longer after being attacked
B．the tower hold stable until all of the people there managed to escape
C．the tower can be immune to such attacks
D．they considered more about the effects of the very' high temperatures and make duel changes in the structure

听力原文： There are wonderful sights to view all around Tower Bridge, too. It is one of the most interesting parts of London. On its south side are many tall and old buildings. They are warehouses which hold goods that is shipped to London and waiting to be sold. On its north side stands the Tower of London itself.
Although they look like the same age, the Tower is more than a thousand years old, and Tower Bridge is over one hundred. It was built in the 1890s. By 1850, everyone disagreed that a bridge across the Thames near the Tower was most necessary. Therefore the designers argued about the new bridge within another thirty years. They took so long because they had two big problems. The new bridge must look like the Tower--everybody said so. It must not look like a modem bridge. But because of the tall ships, it was necessary to have a modern bridge. At last two very clever designers had the idea of an opening bridge. They made it look like the old Tower. All the tall ships can easily come and go. Everyone was so happy.

The first eight lanterns 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 set up on rocky eminences (高处), enormous towers were not the rule. Some of them were made of stone and brick, others of wood or metal. Some of them stood on pilings or stilts; others 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.
Notwithstanding differences in construction appearence, most lighthouses in America shared several features: a light, living quarters, and sometimes a bell (or later a foghorn). They also had quarters, and 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 industry -- 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？
A．The Lighthouse on Little Brewster Island.
B．The Life of a Lighthouse Keeper.
C．Early Lighthouses in the United States.
D．The Modem Profession of Lighthouse-keeping.

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.
