question 1: what are the classifications of industrial fields? In economic research and management, the commonly used classification methods mainly include two major fields, two major categories, three industrial classifications, resource intensity classification and international standard industrial classification.

(1) Classification of two major fields and two major categories. This classification is to classify industries according to the nature of production activities and their product attributes. According to the nature of production activities, the industrial sector is divided into two major areas: the material production department and the intangible production department. The former refers to the department engaged in the production of material materials and the creation of material products, including agriculture, industry, construction, transportation, post and telecommunications, commerce, etc. The latter refers to departments that do not engage in the production of material materials but only provide intangible materials, including science, culture, education, health, finance, insurance, consulting and other departments.

(2) classification of tertiary industries. This classification is the division of industrial structure according to the historical development order of social production activities. The department whose products are directly taken from nature is called the primary industry, the department which reprocesses primary products is called the secondary industry, and the department which provides various services for production and consumption is called the tertiary industry. This classification method has become a common industrial structure classification method in the world.

China's three industries are divided into:

primary industry: agriculture (including planting, forestry, animal husbandry and fishery)

secondary industry: industry (including extractive industry, manufacturing industry, production and supply of electricity, gas and water) and construction industry

tertiary industry: other industries except the first and second industries. According to the actual situation in China, the tertiary industry can be divided into two parts: one is the circulation department, and the other is the service department. Specifically, it can be divided into four levels:

The first level: the circulation department, including transportation, warehousing, post and telecommunications, wholesale and retail trade, and catering.

second level: departments that serve production and life, including finance, insurance, geological exploration, water conservancy management, real estate, social services, agriculture, forestry, animal husbandry and fishery services, transportation auxiliary services, comprehensive technical services, etc.

the third level: departments that serve to improve the scientific and cultural level and the quality of residents, including education, culture and art, radio, film and television, health, sports and social welfare, scientific research, etc.

the fourth level: departments that need to serve the public, including state organs, political party organs and social organizations, as well as the army and police.

(3) Classification of resource intensity

This industrial classification method is divided according to the different resources invested by various industries. According to the relative density of labor, capital and technology in various industries, industries are divided into labor-intensive, capital-intensive and technology-intensive industries.

1. labor-intensive industries. Refers to an industry that mainly relies on a large number of labor for production, but has low dependence on technology and equipment. Its measure standard is that wages account for a large proportion in the production cost compared with equipment depreciation and research and development expenditure. Generally speaking, the current labor-intensive industries mainly refer to agriculture, forestry, textiles, clothing, toys, leather, furniture and other manufacturing industries. With the development of technology and the application of new technology and equipment, the technology and capital intensity of labor-intensive industries in developed countries are also increasing, and they are gradually differentiated from labor-intensive industries. For example, the food industry is classified as a capital-intensive industry in developed countries.

2. capital-intensive industries. Refers to the industry in which the capital cost accounts for a large proportion compared with the labor cost, and the fixed capital and working capital occupied by each worker are relatively high. At present, capital-intensive industries mainly refer to steel industry, general electronic and communication equipment manufacturing, transportation equipment manufacturing, petrochemical industry, heavy machinery industry, electric power industry and so on. Capital-intensive industries are mainly distributed in basic industries and heavy processing industries, and are generally regarded as an important basis for developing the national economy and realizing industrialization.

3. Technology-intensive industries. Refers to an industry that relies much more on technical and intellectual factors than on other factors of production in the production process. At present, technology-intensive industries include: microelectronics and information product manufacturing, aerospace industry, atomic energy industry, modern pharmaceutical industry, new material industry and so on.

At present, technology-intensive industries, such as microelectronics and information product manufacturing, are developing rapidly and become the leading industries that drive the economic growth of developed countries. Therefore, it can be said that the development level of technology-intensive industries will determine a country's competitiveness and economic growth prospects.

(IV) International Standard Industrial Classification

In order to make the statistical data of different countries comparable, the United Nations promulgated >:

question 2: in what fields did the early public relations activities of human beings mainly take place? The large river basin is rich in resources and suitable in climatic conditions, which can meet the initial activities of gathering, fishing and hunting, and it is suitable for the growth of rice, wheat and other crops, which also provides a stable foundation for the future development of agriculture.

Question 3: What kind of social activities does China Tea Middle School belong to? What should I do? Teaching plan and reflection

Activity objective:

Learn more about safe behaviors in life through games.

2. Enhance self-protection awareness.

Activity preparation:

1. The teacher filmed a video of unsafe sex education.

2. Some pictures about children's safe behavior in family life.

3. each person has a foam cushion and a drum.

Activity process:

1. Situation lead-in:

Play a video of a real life scene about children having unsafe behaviors at home or outdoors

-"What did you see in the video?"

2. "pass the parcel Game":

Method: Let the children sit on the foam board around the circle, and put the pictures under the foam board cushion at intervals. When you hear the drumming, flowers will be spread. When the drumming stops, where will the flowers fall? If there is a picture under the foam cushion, the child should explain whether the things in the picture should be done. Everyone can participate in the discussion together to distinguish which behavior is correct and which behavior is incorrect.

The teacher asked questions about the content of the picture, which triggered a discussion among children:

"Should I open the door when I hear a knock at the door? Why? What should I do? "

"Can you throw rubbish or articles down from the window? Why? What should I do? "

"Can you stand on the windowsill or balcony? Why? "

"can you just turn on the gas? Why? "

"can you touch the electrical outlet casually? What are the dangers? "

"can you help yourself to something? What will be the consequences? What should I do? "

"How to go up and down the stairs"

Activity reflection:

After the middle class, children's self-awareness is increasing, but their self-protection awareness is weak, and they can't pay attention to many dangerous behaviors. In order to cultivate children's awareness and behavior of self-protection, this educational activity is designed according to the age characteristics of children in middle class and close to their lives, combined with games. From the beginning of the activity, the unsafe behavior of children was truly reproduced in the form of video tape, so that children could establish safety awareness from the beginning and understand the terrible consequences brought by these unsafe behaviors through children's discussion. Relax the tension of activities through games. What is the right behavior for each child? What behavior is incorrect? Individual children's ability to distinguish right from wrong is cultivated, and the contents of the design are all about children's self-protection consciousness, so there is no doubt about the improvement of children's self-protection consciousness. The activity adopts the method of live demonstration-children's discussion (combined with games), which is in line with the age characteristics of children and full of children's interest. I think it is very good for children to study in a lively and relaxed atmosphere.

Question 4: The four major fields of human activities do not include the era of great development of modern science and technology. People often say that "sea, land, air and sky" are the four major fields of human activities on earth. This also shows that people on earth are really exploring.

Life on the earth originated from the ocean, and later it multiplied on the land through changes. People on earth evolved and developed on land, which was the first place for human activities. Later, human activities gradually expanded to the ocean (navigation), and the ocean became the second field of human activities. Later, it was extended to the space (aviation) in the earth's atmosphere, giving mankind a third field of activity. Earth people, the spirit of all things, are born with the characteristics of being innovative, curious and unwilling to be lonely. After they gradually became familiar with the land, they went to the ocean, to the sky (the earth's atmosphere), and then to chase the boundless universe. With their wisdom and the continuous development of modern science and technology, they marched into the outer space of the earth's atmosphere. To explore the fourth field of human activities ~

Question 5: What are the similarities between the types of early childhood education activities? The content of kindergarten language education includes not only the contents of special activities organized by teachers with a purpose and a plan, but also the greetings from children entering the park, the morning conversation, and the farewell of children when they leave the park. When

there are language education activities in other fields, it can be said that the language education activities in kindergartens are the most extensive and involve the most fields. Therefore, the language education in kindergartens can be roughly divided into two categories: specialized language teaching activities and permeable language education activities. Specialized language education activities include five basic forms: talking activities, telling activities, listening and speaking games, literary activities and early reading. Infiltrated language education activities include

language communication in daily life, language communication in free games, language communication in other fields, and language communication in daily life links that are randomly infiltrated.

question 6: what is the difference between a certain kind of economic activity and an industry in a certain field? That is, the difference between economic activities and industries. Industrial economics is an important branch of applied economics. A new applied economic theory system for analyzing real economic problems in modern western economics. Starting from the "industry" as an organic whole, industrial economics discusses the relationship structure between industries, the laws of organizational structure changes of enterprises within industries and the methods to study these laws in the economic development centered on industrialization. The research object of industrial economics is the law of the interaction between enterprises within the industry, the law of the development of the industry itself, the law of the interaction between industries and the law of the distribution of industries in the spatial region. "Property rights economics" studies the resource allocation rate from the perspective of property rights structure or property rights system, and studies how to create or maintain a property rights system with low transaction costs and high efficiency by defining and changing property rights arrangements.

question 7: what kinds of kindergarten education activities can be classified according to their characteristics? According to the nature of children's learning, kindergarten education activities can be relatively divided into health education activities (including physical and mental health care and physical exercise), language education activities, social education activities, science education activities, mathematics education activities and art education activities (including music and art).

question 8: what are the main types of children's language education activities and the contents of kindergarten language education? It includes not only the contents of special activities organized by teachers with a purpose and a plan, but also the greetings of children when they enter the park, the morning conversation, and the farewell of children when they leave the park. However, there are language education activities in other fields. It can be said that language education activities in kindergartens cover the widest range and involve the most fields. Therefore, language education in kindergartens can be roughly divided into two categories: specialized language education activities and permeable language education activities. Specialized language education activities include five basic forms: talking activities, telling activities, listening and speaking games, literary activities and early reading. Infiltrated language education activities include language communication in daily life, language communication in free games, language communication in other fields, and language communication in daily life links that are randomly infiltrated.
