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.
After reading Fengwawa, think about what the wind can do
Fengwawa, before blowing, ask yourself if it will help others.
Wind doll, you must consider the consequences before doing something! This time you blew up the kite, the clothes and broke the small tree by the side of the road. If you continue to blow, then houses, villages... will disappear and the consequences will be disastrous.
Feng Wawa's intention is to help people do things. At first, she only thought about helping people if she had the strength, buts she also did bad things. In other words, she realized she had done something wrong. Then the things that the wind doll can also do include: 1. Blow up the windmill that generates wind power. 2. Blow the water on the lake, 3. Blow the branches of the trees. Blowing the clouds in the sky......
