1. Prepare food: Wind can accelerate water loss, such as air-dried meat, air-dried fruit pulp, etc. Xinjiang raisins are a typical dried food.
2. Dry clothes: Wind can accelerate the evaporation of water on clothes, accelerate water loss, and speed up drying of clothes.
3. Wind power generation and irrigation: The wind can rotate the blades of the windmill, and then increase the rotation speed through the increase in speed to prompt the generator to produce electricity. Wind energy is a non-polluting, clean and renewable energy. Ancient people also used windmills to water crops.
4. Help fruit trees and crops bloom and bear fruit: the wind can carry away pollen, fertilizing fruit trees and cropses so that they flower and bear fruit.
5. Electricly Assisted Sailing Ship: In ancient times, ships without electrical systems relied on wind power to move, which greatly reduced the duration of the voyage.
Work appreciation:
"Wind Doll" is a text from lesson 24 of unit 8 of the second grade Chinese language edition year compiled by the Ministry of Human Resources and Education. This text appears in the form of a favorite story for primary school students. Through Feng Wawa's "good intentions do bad things", he vividly presents the benefits and harms that the wind brings to people, allowing students to understand. that “it is not enough to have good wishes, but it also depends on whether it is useful to others.”
Wind is a natural source of energy. Long ago, humans learned to fbuild windmills and use wind energy to pump water and process food. The movement of a sailboat is also determined by the wind. Wind plays many roles in daily life, but it also often causes disasters for humans. Storms, typhoons, hurricanes, tornadoes, etc. are very harmful to humans.

6. The wind will drive away the dark clouds and mist: When the dark clouds block the sun, it is the wind that blows them away, allowing the sun to fill the earth again. When pollution is heavy in winter, it can make smog disappear.
7. During the hot summer, the wind brings us coolness and drives away mosquitoes.
8. Bringing rain:the wind can blow the clouds, promote the exchange of dry, cold and hot and humid air, and adjust the air temperature and humidity. This is what the ancients said: “The clouds turn into rain, and the dew turns into frost. Wind can send clouds and rain to distant locations, completing the water cycle on Earth. In summer, warm, humid air coming from the ocean brings abundant precipitation.
Detailed information:
Wind is also a “double-edged sword”. maybe both Helping people will have a negative impact on people's lives.
It can spread pathogens and spread plant diseases; high-altitude winds are the weather conditions that allow locusts and other pests to migrate long distances; strong winds can cause mechanical scratching of leaves, lodging of cultures, broken trees, and falling flowers and fruits, affecting yields. Strong winds also cause soil erosion, shifting sand dunes and damage to agricultural land. Additionally, wind presents greater dangers. Indiscriminate reclamation of drylands will lead to land desertification; strong winds and snowstorms in pastoral areas can disperse livestock and worsen frost damage; some special properties of local winds often cause damage by wind blowing from the sea. Maritime tidal winds are high; -High and low temperature foehn winds as well as hot and dry winds all seriously affect the flowering and fruit set of fruit trees as well as the grain filling of cereal crops.
To reduce wind damage, certain measures can be taken to prevent wind damage.wind damage. For example, dwarf, lodging-resistant and scrub-resistant varieties are often grown. Additionally, building windbreaks and installing wind barriers are even more effective methods of wind protection.
