1. Fengwa has done so many things for people in the dark. The first thing is the most common thing in life, that is, Fengwa helps people dry them.
2. The wind doll can also bring rain to people. She can chase away dark clouds. The most important thing is that it can exchange dry, cold air with warm, humid air over a large area. to regulate the air temperature appropriately.
3. The wind doll has silently helped people a lot. It can also generate electricity for people. The wind doll can really make all the blades of the windmill rotate quickly, then people can increase the speed.
4. Plus the weather in summer is so hot. Only the wind doll can help people blow cool wind, and it can also drive away those pesky flies at the same time.
Informationdetailed:
Once the wind gets angry, it will be harmful rather than useful.
1. Strong winds blow a lot of sand and dust onto the ground and roll it into the air, making the air extremely cloudy and horizontal visibility very poor. Strong winds carrying fine sand and dust destroyed buildings and public facilities, causing human and animal losses.
2. Typhoons always cause all kinds of damage. They are sudden and destructive and constitute one of the most serious natural disasters in the world. The heavy rains and the tsunamis it causes are powerful and destructive.
3. It is a powerful small-scale air vortex, generated by strong convective air movement in extremely unstable weather conditions, accompanied by funnel-shaped cloud columns rotating atgreat speed. near the center of a vortex can reach 100 ms to 200 ms, with a maximum of 300 ms, which is several times higher than the maximum wind speed near the center of a typhoon. It is extremely destructive.
4. If we don't pay attention, the things we need will be taken away without a trace. When the wind gets angry, it blows away many things, even doors, windows, houses and crops. , and flowers and fruits.

Wind can help people do the following things:
1. Prepare food: Wind can accelerate water loss, asand that of air. dried meat and air-dried fruit pulp await. Xinjiang raisins are a typical dried food.
2. Drying 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 turn 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 windmills were also used to water crops.
4. Help fruit trees and crops bloom and bear fruit: The wind can carry away pollen, fertilizing fruit trees and crops to flower and bear fruit.
5. Electrically assisted sailboat: in ancient times, navires without an electrical system relied on wind power to travel, which greatly reduced travel time.
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 and flies.
8. Bringing rain: The wind can blow the clouds, promote the exchange of dry, cold and warm 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 precipitationabundant iterations.
Wind is also a “double-edged sword”. It can not only help people but also have a negative effect on their 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 crops, 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 poses greater dangers. Indiscriminate reclamation of drylands will lead to land desertification due to wind.
Strong winds and blizzards in pastoral areas can disperse livestock and worsen frost damage; cerSome special properties of local winds often cause wind damage; salty tidal winds blowing from the sea can cause Foehn winds and high and low temperatures. hot, dry winds have seriously affected flowering, fruit set and grain filling of fruit trees.
The wind doll not only helps us humans, but it also helps small animals. She helps birds spread their wings, helps them learn to fly, and helps them. the swallows. Help many small animals to fly in the sky etc.
It also helps people to ripen fruits, helps farmers to ripen crops, and helps children to put kites in the blue sky, amusing every child and them. growing healthy.
Text Summary
The wind blew people's clothes to dry and broke the newly planted treesstanding by the side of the road... His mother told him that it is not enough to do things with the good. intentions. , but also to see if it is really useful to others.

When Feng Wawa saw the waterwheel rotating slowly, he took a deep breath and blew vigorously on the waterwheel. Water flowed into the field. The seedlings drank enough water and waved happily.
He saw that the wind turbine generator was spinning very slowly, took a deep breath and blew up the wind turbine generator. The wind turbine generator spun quickly and the house lights came on.
He saw that the children's kites could not fly, and blew gently, and the kites flew away.
