Read the following text and choose the most suitable heading from A-F for each paragraph. There is one extra heading which you do not need.

PARIS

小题1:Paris, the capital and the largest city of the country, is in north central France. The Paris metropolitan area contains nearly 20% of the nation’s population and is the economic, cultural, and political center of France. The French government has historically favored the city as the site for all decision making, thus powerfully attracting nearly all of the nation’s activities.

小题2:Paris has grown steadily since it was chosen as the national capital in the late 10th century. With the introduction of the Industrial Revolution, a great number of people moved to the city from the country during the 19th century. The migration was especially stimulated by the construction of railroads, which provided easy access to the capital. After World War II more and more immigrants arrived.

小题3:The city is the centralized control point of most national radio and television broadcasting. It is a place of publication of the most prestigious (有威望的) newspapers and magazines and an international book publishing center. With more than 100 museums, Paris has truly one of the greatest concentrations of art treasures in the world. The Louvre, opened as a museum in 1793, is one of the largest museums in the world.

小题4:In the late 1980s about 4.1 million pupils annually attended about 47,000 elementary schools. In addition, about 5.4 million students attended some 11,200 secondary schools. Approximately 1.2 million students were enrolled annually at universities and colleges in France in the late 1980s. French centers of learning have served as academic models throughout the world.

小题5:Paris is the leading industrial center of France, with about one quarter of the nation’s manufacturing concentrated in the metropolitan area. Industries of consumer goods have always been drawn to Paris by the enormous market of the big population; and modern, high-technology industries also have become numerous since World War II. Chief manufactures are machinery, automobiles, chemicals and electrical equipment.
