Read the following materials and answer the following questions. Material 1: Fog is countless small water droplets formed by condensation of water vapor near the ground; Haze is suspended near the ground.

(1)① In winter, a large number of coal-fired power generation and heating, emitting a lot of smoke and dust; (2) the number of cars is large, and the exhaust gas is large; ③ Heavy chemical industry is concentrated, and a large amount of waste gas is discharged; (4) The construction site produces more dust; (5) A large number of straws are burned in autumn in farmland, resulting in a large amount of smoke and dust; 6. Less precipitation in autumn and winter, more sunny days and dry weather; ⑦ There is no obvious cold air activity, the wind is small, and the atmospheric stratification is relatively stable.

(2)① The rising incidence of respiratory diseases is harmful to human health; (2) The visibility decreases, which is prone to traffic accidents and affects traffic travel; (3) aggravate air pollution and expand the scope of pollution; (4) worsen the living environment and hinder economic development.

(3)① Formulating relevant policies and regulations and establishing cross-regional joint prevention and control mechanism; ② Optimize the energy structure and actively develop clean energy; ③ Energy conservation, emission reduction and air pollution prevention; (4) developing public transportation and controlling the number of cars; ⑤ It is forbidden to burn straw to realize the comprehensive utilization of regenerated straw.

Test analysis:

(1) Haze refers to the turbidity caused by the suspension of a large number of particles such as smoke and dust. The core substance of smog is dust particles (dust, sulfuric acid, nitric acid, organic hydrocarbons and other particles) suspended in the air, which can make the atmosphere turbid, blur vision and worsen visibility. A is located around Bohai Sea, with developed economy and large population. It is cold in winter, burning coal for heating, emitting a lot of smoke and dust, a lot of cars and a lot of waste gas. Heavy industry is developed, heavy chemical industry is concentrated, and a large amount of waste gas is discharged; The urbanization speed is fast, and a large amount of dust is produced in construction sites; In autumn, a large number of straws are burned in farmland, resulting in a large amount of smoke and dust; There is less precipitation in autumn and winter, more sunny days and dry weather; There is no obvious cold air activity, the wind is small and the atmospheric stratification is relatively stable.

(2) Haze weather is disastrous weather, causing diseases such as dermatosis, asthma and cancer, endangering human health, reducing visibility, causing traffic hazards and affecting normal industrial production, work and study.

(3) The control measures of smog should be aimed at the causes of smog. The government should introduce strong laws and regulations, strengthen management, adjust industrial structure, speed up industrial upgrading and develop high technology? Industry, eliminate industries with high energy consumption and high pollution, adjust energy structure, improve energy utilization rate, give priority to the development of public transportation and control traffic congestion; Improve automobile exhaust emission standards, stop and turn off the engine, and reduce automobile exhaust emission; Advocate green travel such as walking and central heating in winter, and move heavily polluting enterprises to the suburbs.

This question is more open, as long as it makes sense. )
