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 governments have 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 WarⅡ, 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 important newspapers and magazines and an international book publishing center.

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.

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 consumers’ 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 WarⅡ. Chief manufactures are machinery, automobiles, chemicals and electrical equipment.
