Read the material and answer the following questions. Material 1: As shown in the figure, since16th century, there has been a large influx of European immigrants in Area B.. At present, Area B is the world metropolitan area. (1) Looking at the map, we can see that the land area where A is located is small and close to the ocean. Due to the influence of the ocean and the difference of thermal properties between land and ocean, the temperature drops slowly or slightly. Combined with the topographic features, it is located in the east of the Andes, on the leeward slope of the west wind, with less precipitation and more sunny days, and the temperature is higher than 0℃ in winter.

(2) It can be calculated that Sao Paulo is located in the west third district, which is 1 1 hour away from the east eighth district. According to the principle of "adding east and subtracting west", Beijing time can be calculated as June 12, 17: 08+0 1 hour = June 1 hour. Sao Paulo is located in the low latitudes of the southern hemisphere. Although it is winter, the climate is mild and there is little precipitation.

(3) The difference of hydrological characteristics between the two rivers is mainly manifested in the discharge and its change. M river passes through tropical rain forest climate zone and savanna climate zone, with large flow and small seasonal variation, while N river mainly flows through savanna climate zone, with obvious dry and wet seasons in one year, small river flow and large seasonal variation.

(4) The benefits of China-Brazil joint construction of steel mills in Brazil to China: China can directly use Brazilian local iron ore to avoid being controlled by international iron ore enterprises, and at the same time expand the international market and strengthen economic exchanges with Brazil; For Brazil, resource advantage has been transformed into economic advantage, which has improved the self-sufficiency rate of steel products, reduced the dependence of steel products on the international market, promoted local economic development and improved the level of industrialization. This is "win-win" for both sides.

So the answer is: (1) is small; Far from the sea, it is greatly influenced by the ocean; In winter, it is located on the leeward slope of the west wind.

(2) 4 o'clock on13? Mild and little rain.

(3) Difference: The discharge of M River is large, but the runoff changes little in season.

(4) For China: directly use Brazilian iron ore; Expand the international market. For Brazil, it is conducive to transforming resource advantages into economic advantages; Reduce the dependence of steel on the international market and improve the self-sufficiency rate of steel; Improve the level of industrialization.
