By 1862 telegraph communications linked San Francisco with eastern cities, and by 1869 the first transcontinental railroad connected the Pacific coast with the Atlantic seaboard. Today San Francisco has a population of almost three million. It is the financial center of the west, and serves as the terminus for trans-Pacific steamship lines and air traffic. The port of San Francisco, which is almost 18 miles long with 42 piers, handles between five and six million tons of cargo annually.
And now, if you will look to your right, you should just be able to see the east section of the Golden Gate Bridge. The bridge, which is more than one mile long, spans the harbor from San Francisco to Marin County and the Red Wood Highway. It was completed in 1937 at a cost of 32 million dollars and is still one of the largest suspension bridges in the world.

听力原文： From this lookout we enjoy one of the most spectacular views of San Francisco. As you can see, the city rests on a series of hills varying in altitude from sea level to nine hundred and thirty-eight feet.
The first permanent settlement was made at this site in 1776. For thirteen years the village had fewer than one hundred inhabitants. But in 1848, with the discovery of gold, the population grew to ten thousand. The same year the name was changed from Yerba Buea to San Francisco.

Today San Francisco has a population of almost three million. It is the financial center of the west, and serves as the terminus for trans-Pacific steam ship lines and air traffic. The port of San Francisco which is almost eighteen miles long with forty-two piers, handles between five and six million tons of cargo annually.

Now the city plans to extend public access to the area adjoining Moon Walk in an ambitious design that will, the city hopes, be a part of its development for the next world's fair. This more ambitious concept for the waterfront will be likely to stir considerable debate as competing projects vie (竞争) for the opportunities for profit. The development will therefore require substantial participation, cooperation and scrutiny (详细审查) by citizens to make sure that while private profitability is maintained, the public's needs are satisfied, too.
The joint efforts of environmentalists, business-people, civic leaders and politicians have transformed abandoned, derelict (废弃的) port landscapes in cities throughout America into exciting commercial and recreational centers. Examples are the Cannery in San Francisco, the Riverfront Walk in San Antonio, Faneuil Hall Market in Boston and Harborplace in Baltimore.
It's easy to understand why the port areas were neglected. While many cities were growing up along rivers, lakes and natural harbors, depending on water-borne commerce, waterfronts thrived. After World War Ⅱ, however, technological changes in transportation— improved planes and airports, the interstate highway system, larger tracks for freight trains and containerized shipping--rendered many old port facilities obsolete. Waterfront areas became peripheral (外围的) to the life of the city. Piers were abandoned, and the waterfronts lay idle in many older cities, paralleling the more general urban decay.
With the 1970's came a period of reflection on this condition and a resurgence (苏醒) of urban pride. urban renewal stopped being a license for large-scale demolition (破坏); politicians and planners took a hard. look at their available resources and began to experiment with new development techniques. Waterfronts became one focus of the large urban revitalization effort.
The primary purpose of this passage is to describe ______.
A．business expansion of urban areas
B．Moon Walk in New Orleans
C．the causes of urban decay
D．the renewal of waterfront areas
