7. Climatic characteristics of Asia: The climate types are complex and diverse, and the monsoon climate and continental climate are widely distributed. Methods The climatic characteristics of other continents were analyzed: the distribution law of climatic types and which climatic type is the most widely distributed. The characteristics of monsoon climate: high temperature in summer, low temperature in winter, and great seasonal variation of precipitation, concentrated in summer and autumn, with both rain and heat.

8. Ranked by population: Asia, Africa, Europe, South America, North America, Oceania; Ranked by natural population growth rate: Africa, South America, Asia, Oceania, North America and Europe.

10, a country's industrial structure is an important indicator to measure a country's economic development. The higher the per capita GNP, the more developed the economy, the larger the tertiary industry, the lower the per capita GNP, the more backward the economy, and the greater the proportion of the primary industry.

Asian economic differences: the eastern coast is developed, the western inland economy is backward, the economic development of different land and sea locations is different, and the economic development is different under different social and historical conditions.

Chapter 7: Our Neighboring Countries and Regions

1. Geographical location: land and sea location (Northwest Pacific), continental location (East Asia), latitude location (wide latitude and longitude span) 23° N-46° N,122 E-148 E, Japan's north and south land is long and narrow, intersecting with longitude.

2. Topographic features: A typical island country, consisting of four islands (Hokkaido, Honshu, Shikoku and Kyushu) and more than 3,900 small islands; The land area is 377,000 square kilometers; The coastline is tortuous and there are many excellent ports (such as Kobe and Yokohama). The terrain is dominated by mountains, the plain area is narrow, and there are many volcanoes and earthquakes (Japan is located at the junction of the Pacific plate and the Eurasian plate, with frequent and unstable crustal activity).

3. Developed processing trade economy: Japan is a world economic power, a processing trade economy, and highly dependent on foreign countries. It must import raw materials from abroad and export finished products.

4. Major industrial zones in Japan: Keihin Industrial Zone, Nagoya Industrial Zone, Setouchi Industrial Zone, Hanshin Industrial Zone and Kitakyushu Industrial Zone; Distribution characteristics: Japanese industry is highly concentrated, mainly distributed in the inland sea coast of Seto and the Pacific coast.

5. Cultures compatible with the East and the West: Traditional colors and modern atmosphere coexist, and cultural exchanges between China and Japan have a long history.

6. Japan's investment measures: expand overseas investment and establish overseas production and sales bases, mainly for the United States, Western Europe and Southeast Asia; The advantages of overseas investment in building factories for Japan: using cheap labor in developing countries; Reduce the input cost of industrial production; Participate in international economic and technological cooperation and international market competition; Protect the country's natural resources, slow down resource consumption, protect the country's environment and reduce the input of transportation costs. The impact of Japanese overseas investment on other countries: Japan's relocation of heavily polluting enterprises overseas will pollute the environment of other countries and lead to a decline in environmental quality; Japan has a strong sense of protecting its own resources from its own interests, but importing a large amount of wood or overfishing in the ocean will lead to serious damage to the resources of other regions or countries in the world, which will lead to the imbalance of the global ecological environment.

7. Southeast Asia: including Indochina Peninsula and Malay Archipelago; Country (total 1 1 country): Vietnam, Laos, Indonesia (the country of thousand islands, the largest archipelagic country in the world), Cambodia, Thailand, Malaysia, Singapore, Philippines, Brunei and East Brunei.

2. Why is rice the main food crop in Southeast Asia? Rice is a major food crop, but its production requires a lot of labor, high temperature and rainy conditions. Southeast Asia is densely populated, less cultivated, hot and rainy, and taking rice as the main food crop is an inevitable condition. Distribution of tropical cash crops in Southeast Asia: Thailand, Vietnam and Myanmar are important rice exporters in the world; Thailand is the largest rubber producer in the world; The Philippines is the world's largest producer of banana cannabis and exporter of coconut. Malaysia is the largest palm oil producer in the world; Indonesia is the largest coconut producer in the world.

3. Most rivers in Southeast Asia originate from the Qinghai-Tibet Plateau in China, such as Mekong River (Lancang River) and salween River (Nujiang River). The characteristics of rivers are: north and south, mountains and rivers alternate with each other, the rivers run through mountains, the mountains on both sides are towering, the water is swift and the hydropower resources are rich. The lower continental valley widens, the water flow is slow, and sediments are deposited. Alluvial plains are formed on both sides of the river bank, and rivers are formed at the estuary, with low terrain and fertile soil.

4. Why are cities located in the delta along the Yangtze River and the estuary? Because these places have fertile land, flat terrain, easy irrigation and convenient transportation, they are important agricultural areas in Southeast Asia with dense population and developed agriculture, which also provide favorable conditions for the development of cities, such as Chongqing, Wujiang and Shanghai in China.

5. Geographical location: Located in the southwest of China, India is one of the four ancient civilizations. India's neighbors are Pakistan, China, Nepal, Bangladesh, Myanmar and Sri Lanka across the sea. India's terrain can be divided into three major terrain areas: the mountains in the south of West Malaya in the north, the Ganges Plain in the middle and the Deccan Plateau in the south.

6. The total population of India has exceeded 1 billion, making it the second most populous country in the world. In the past 50 years, the population of India has almost tripled. The main feature of India's population problem is the rapid population growth. Since the 1970s, the Indian government has adopted population control policies and incentive plans, but the traditional concepts in the vast rural areas of India are still very strong. For a long time, the annual net increase of India's population will be larger and larger. Due to India's overpopulation, India's per capita natural resources, per capita grain output and steel output are far from the world average. This shows that the rapid population growth will have a serious negative impact on a country's resources, environment and economic development.

7. Most parts of India are located in the tropics and subtropics, characterized by tropical monsoon climate: high temperature all year round, rainy season and dry season. In the rainy season (June-September), the wind blows from the ocean to the land (southwest wind), and in the dry season (10- May of the following year), the wind blows from the mainland to the ocean (northeast wind). Monsoon causes frequent floods and droughts in India. For example, the monsoon comes early and leaves late, and floods are formed when the wind is strong; The monsoon comes late and leaves early, and the weak wind forms drought.

8. The breakthrough of India's rapid grain growth lies in the implementation of the "green revolution". Rice and wheat are the main food crops in India, and their yields are among the highest in the world. Rice is mainly distributed in the Ganges plain and coastal plain with sufficient precipitation and flat terrain; Wheat is mainly distributed in the upper reaches of Ganges River and the northwest of Deccan Plateau with less precipitation and plenty of sunshine. This also shows that agricultural production is closely related to natural conditions.

9. Indian industry. During the British rule, textile and mining industries were mainly developed. This is because Britain strictly controls Indian industry for its own economic development. At that time, the level of science and technology in India was quite backward. After independence, India actively introduced foreign capital and advanced technology, attached importance to training scientific and technological talents, and made great efforts to develop its own industries, mainly steel industry, machinery industry, chemical industry and cotton and linen textile industry, and also made certain achievements in high-tech fields such as atomic energy, aerospace and computer software.

10. General situation of Russia: ① Terrain: relatively flat, mainly plain, with plain to the west of Ural Mountain, followed by western Siberia plain, central Siberia plain and eastern Siberia. It is the largest country in the world, with a length of 10000 square kilometers from east to west and a width of about 4000 kilometers from north to south, covering an area of over17 million square kilometers. ② Climate: Temperate continental climate is dominant. There are great differences among regions, with polar climate in the north being cold all year round, Mediterranean climate and temperate grassland climate in the south and temperate monsoon climate in the east. The climate in Russia: winter is long and cold, and summer is short and warm; ③ Rivers and lakes: The Volga River is the longest river in Europe, rich in hydraulic resources and the most important inland waterway. Ob river, Yenisei and Lega rivers are rich in energy and have a long freezing period. Lake Baikal is the deepest lake in the world; ④ Rich in natural resources. There are many kinds, large reserves, uneven regional distribution, more in the east and less in the west. The main minerals are: oil, natural gas, coal, iron ore, non-ferrous metals and so on. The main producing areas are Kursk Iron Mine, Kuzbas Coal Mine and Tyumen Oilfield.

1 1, four major industrial zones: the industrial sub-zone centered on Moscow is distributed in the European part of Russia, and it is the most developed region in Russia, mainly including steel, automobiles, airplanes, rockets and electronics; The industrial zone centered on St. Petersburg is located on the Baltic coast of European part of Russia. Petrochemical, shipbuilding, electronics, papermaking and aerospace industries are very developed here. It is also the most developed area of Russian food and textile industry; Ural Industrial Zone, located in the Ural Mountains, is located on the dividing line between Asia and Europe. The main products here are petroleum, steel and machinery. Siberian industrial zone centered on Kuzbas: mainly produces heavy industrial products such as coal, oil, natural gas, electric power, steel and military products.

12. Why should Abel Railway be built along the southern mountainous area? The first reason is that the southern mountainous areas are rich in mineral resources. Secondly, because of the high latitude, cold all the year round and low temperature in northern Russia, the frozen soil layer is deep. It is difficult to build a railway on frozen soil, and the safety factor is low. Pipeline transportation is a new mode of transportation that combines lines and means of transportation, mainly transporting oil and natural gas. Two main modes of transportation: road and railway; There are two main modes of goods transportation: pipeline and railway.

Unit 6 The continent where we live-Asia

I geographical location, topography and rivers in Asia

1. Location:

① Hemispheric location of Asia: Most of Asia is located in the Eastern Hemisphere and the Northern Hemisphere, but it spans both the Eastern Hemisphere and the Southern Hemisphere. ② Latitude position of Asia: Asia is roughly located between 10s-80n, spanning tropical, temperate and frigid zones, and is the continent with the highest latitude in the world. ③ Land and sea location: Asia borders the Pacific Ocean in the east, the Arctic Ocean in the north, the Indian Ocean in the south and Europe in the west. The dividing lines are the Urals, ural river, the Great Caucasus, the Black Sea, the Turkish Strait and the Mediterranean Sea. It is adjacent to Africa across the Suez Canal in the southwest, North America across the Bering Strait in the east, and Oceania across the sea in the southeast. Asia is the farthest continent from east to west.

2. Area: Asia is the largest continent in the world. The seven continents are arranged in size: Asia, Africa, North and South America, Antarctica and European seas.

3. Geographical division: traditionally, Asia is divided into six regions: East Asia, Southeast Asia, South Asia, Central Asia, West Asia and North Asia. The following table shows the regions and countries:

Part of Russia in North Asia

4. Terrain:

(1) Topographic features: Plateau and mountains are the main areas, with high average elevation; The land fluctuates greatly, including Mount Everest (8844 meters), the highest mountain in the world, and the Dead Sea (400 meters), the lowest in the world. It is the continent with the largest ground fluctuation in the world. The terrain is high in the middle and low around.

(2) The highest mountain in the world is in Asia: the Himalayas; The highest mountain: Mount Everest; The highest plateau: Qinghai-Tibet Plateau; The largest saltwater lake: Caspian Sea; The deepest and largest freshwater lake: Lake Baikal; Lowest point of land surface: Dead Sea; The largest peninsula: Arabian Peninsula; The largest archipelago: Malay archipelago; The largest landlocked country: Kazakhstan; The most populous country: China; The longest canal: Beijing-Hangzhou Canal)

5. Rivers: Asian rivers are influenced by topography, mostly originating from the central plateau and mountainous areas, and flow radially into the sea along the topography. The main rivers flow in the following table:

Characteristics of river flow into the ocean

The length and flow of the Yangtze River from west to east ranks first in Asia and third in the Pacific world.

The Yellow River is 5500 kilometers long from east to west, and it is the second longest river in China, the Pacific Ocean.

Mekong River is called Lancang River from northwest to southeast in China, and Asia flows through the Pacific Ocean, which is the largest river flowing through the country.

Ob river, Yenisei River and Lena River are located in northern Asia from south to north, with high latitudes, and the ice age of rivers in the Arctic Ocean is longer in winter.

The Ganges River is located in the south of Asia and flows through the Indian Ocean of India and Bangladesh from west to east.

The Indus River is located in southern Asia from north to south and flows through the Indian Ocean in Pakistan.

Second, the complex climate.

1. Climate characteristics:

① The climate is complex and diverse: Asia spans the cold zone, temperate zone and tropical zone, borders the ocean on the east, north and south, and goes deep into the Eurasian continent in the southwest; The terrain is complex and diverse. Affected by latitude, land and sea distribution and topography, the climate in Asia is complex and diverse. Except temperate maritime climate, all kinds of climate in the world are distributed in Asia.

② The monsoon climate is remarkable: Asia is backed by Eurasia, the largest land in the world, and close to the Pacific Ocean, the largest ocean in the world. The temperature difference between the ocean and the land is remarkable, forming the most typical monsoon climate zone in the world. Tropical monsoon climate, subtropical monsoon climate and temperate monsoon climate are all distributed, among which tropical monsoon climate and temperate monsoon climate are only distributed in Asia.

(3) Continental climate distribution (temperate continental climate accounts for almost half of Asia): Asia is the largest continent in the world, with a vast area, and the inland is far away from the ocean and is less affected by the ocean. The inland temperature rises rapidly in summer and cools rapidly in winter, so Leng Xia is hot in winter. Because the inland is far away from the sea, it is difficult for ocean water vapor to reach, so the precipitation is less and concentrated in summer.

2. Impact of climate on agriculture: In Asia, the impact of monsoon climate on agriculture is particularly prominent. In the monsoon climate regions of East and South Asia, precipitation is closely related to the strength of summer monsoon. Generally speaking, in the year with strong summer monsoon, there are more water vapor and precipitation from the ocean; On the contrary, in the year when the summer monsoon is weak, there is less precipitation. If there is too much precipitation, it may cause floods; On the contrary, if there is too little precipitation, drought may occur. Therefore, the simultaneous rain and heat in East Asia and South Asia (monsoon region) make crops grow vigorously, but under the influence of unstable summer monsoon, droughts and floods often occur, which seriously threatens agricultural production.

Highlights: (l) The world's most populous continent: Asia's population is 6 1%.

① The world's continents or regions are ranked as Asia, Africa, Europe, Latin America, North America and Oceania according to their population. Ranked by the average natural population growth rate: Africa, Latin America, Asia, Oceania, North America and Europe.

② There are 10 countries with a global population of over 10, of which 6 are located in Asia: China and Japan in East Asia, Indonesia in Southeast Asia, India, Pakistan and Bangladesh in South Asia.

(3) the impact of large population on resources and environment:

2. Diversified regional culture: There are about 1000 ethnic groups in Asia, accounting for about half of the total ethnic groups in the world (ethnic groups in different regions show different cultural and artistic styles and different folk customs in architecture, clothing, music, dance and etiquette). Such as: earthquake-resistant buildings in Japan, tents and robes in Saudi Arabia. The Yellow River in Asia-the middle and lower reaches of the Yangtze River, the Indus Valley and the Mesopotamian Plain (two river basins) have become the cradles of human civilization respectively because of their suitable temperate or tropical climate, abundant water resources and fertile land.

3. Economic development: Asia is a developing country except Japan. The economic development of different countries varies greatly. The main reason is that all countries except Japan have been under colonial rule for a long time, and their industrial base is generally weak. Since 1970s, the economies of Singapore, Korea, Malaysia and Thailand have developed rapidly.
