"Wind Baby" is a beautiful fairy tale that is easy to understand, with lively language and full of children's interest. In the text, Feng Wawa thought that he could do good things if he had the strength, but ended up doing bad things with good intentions, letting the children understand that it is not enough to just have good intentions when doing things, but also to see whether they are really useful to others.
Let children understand that it is not enough to do something with good intentions, but also to see whether it is really useful to others.
Feng Wawa came to the field and saw a large windmill turning slowly, and the water pumped up was flowing intermittently. He took a deep breath, puffed up his cheeks and blew hard towards the windmill. The windmill suddenly turned very fast! The pumped water rushed and flowed into the fields. The rice seedlings drank enough water and nodded with a smile. Feng Wawa was very happy.
Feng Wawa came to the river again and saw many boatmen pulling a big boat. They were bent over, sweating, and shouting "Hey, hey," but the boat moved very slowly. He hurried over and blew hard on the sail, and the ship started running quickly. The boatmen smiled and expressed their gratitude to the wind doll while putting away the rope.
Extended informationWind can help people do the following things:
1. Make food: Wind can accelerate the loss of water, such as air-dried meat, air-dried fruit pulp, etc. Xinjiang raisins are a typical dried food.
2. Blow dry clothes: Wind can accelerate the evaporation of water on clothes, speed up water loss, and make clothes dry faster.
3. Wind energy generation and irrigation: The wind can drive the windmill blades to rotate, and then increase the speed of rotation through the speed increaser to prompt the generator to generate electricity. Wind power is pollution-free, clean energy, and renewable. Ancient people also used windmills to water crops.
4. Help fruit trees and crops to bloom and bear fruit: Wind can blow away pollen, fertilizing fruit trees and crops to bloom and bear fruit.
5. Power-assisted sailing ship: In ancient times, ships without a power system relied on wind energy to move, which greatly reduced the voyage time.
6. The wind will blow away the dark clouds and haze: When the dark clouds block the sun, it is the wind that drives them away, allowing the sun to fill the earth again. When pollution is serious in winter, it can blow away the smog.
1. Inspect, clean and lubricate all rotating parts once a year;
2. Check wire ropes, rigging and all fastening connections every year Clean the surface before the rainy season and apply anti-rust oil;
3. Lubricate and maintain the generator bearings every one year of operation;
4. Lubricate and maintain the wind turbine every two years All open-air parts shall be cleaned, rust removed and painted once. 1. The open-air parts are all made of stainless steel or have undergone special long-term anti-rust treatment, so there is no need to maintain the appearance;
2. The generator uses high-grade bearings and high-grade lithium-based grease. Check the bearings after 5 years of operation and add appropriate amounts of grease if necessary.
