Bees make sounds by vibrating their wings.
Original text: The Cry of the Bees
One day, an 11-year-old girl came to the apiary to play and found many bees gathered on the hive, their wings not flapping, but still buzzing. She remembered the principle of bee vocalization in "100,000 Whys": the buzzing of bees comes from the vibration of their wings, up to 200 times per second, and if the wings stop vibrating, the sound also stops.
But now the bee's wings are not vibrating, but they are still buzzing. What exactly is this sound coming from? She went to ask the teacher, who thought that what the book said was not wrong.
So, she decided to find out for herself. She glued the wings of the bees to the wooden board, and the bees still made sounds. She simply used scissors to cut off its wings, and the bees were still buzzing.
In this way, the two methods were alternated 42 times, using 48 bees each time, and the results were very different from the conclusions in the book. In order to find out the secret of the bee's vocalization, she glued the bee to the wooden board, searched it carefully with a magnifying glass, and observed it for a month, and finally found two small black dots smaller than rape seeds at the base of the bee's wings. When the bee makes a sound, the small black dots agitate up and down; She pierced the little black dot with a pin, and the bee stopped making a sound.
She found some bees, and without damaging their wings, she only pierced the small black dots, and the bees flew around without making a ......soundA year later, the 11-year-old girl wrote a scientific essay "Bees Don't Make Sounds by Wing Vibrating", and won the Silver Award for Outstanding Projects and the Coats Science Popularization Special Award at the 18th National Youth Science and Technology Innovation Competition. She is Nie Li, a fifth-grade student at the Central Primary School in Huangxiekou Town, Jianli County, Hubei Province.

Yes, bees can make sounds without wings.

1. The little girl went through 42 experiments, and the result was ( ) and the conclusion in the book was ( ), so we can know that the meaning is very different ( ).
2. The little girl finally came to the following scientific conclusions through observation experiments:
3. What was the reason for the success of the trial? (Write at least three main points) 1Bees do not make sounds by vibrating their wings, but by their vocal organs.
Bees make sounds by vibrating their wings.
The difference is significant. 2.Bees do not make sounds by vibrating their wings, but have vocal organs.
3.Scientific rigor.
Good at finding problems, finding problems, and solving problems.
Experiment yourself and have the courage to challenge authority.

The importance of bees in nature and human society is almost roughly reflected in the bee text. Bees are one of nature's top pollinators and have an irreplaceable role in agricultural production. Bees not only pollinate crops, but also produce useful substances such as honey and beeswax.
Bees are also social insects that can produce and survive efficiently through close group cooperation. Therefore, it makes great ecological and economic sense to protect bees and strengthen research on them.
A further extended view is that bees are considered to be one of the important indicators of environmental pollution and ecological imbalance. At present, due to the interference of human activities and human factors, the global population of the pre-macro group of honeybees is declining significantly, which not only affects the balance of natural ecology, but also brings hidden dangers to the global agricultural industry. Therefore, protecting the safety and health of bees is an urgent task facing mankind.
At the same time, bees also provide us with a lot of inspiration and reference in terms of sociality. People are constantly learning and studying the group behavior and organizational structure of bees, in order to find more efficient and organic organizational forms and working methods in human society.
In conclusion, the bee text almost reveals the importance of protecting bees and studying their lives and behaviors, as well as new ideas for the working methods and organizational structures of human society. This is closely related to our daily 1110 and also affects future economic and social development. <>

Summary. The words in the bee reading essay include "ecological environment", "tandem", "communication", etc., which can indicate that it is about the ecosystem, emphasize the interconnectedness and role of organisms, and indicate that various organisms must be connected and supported by each other in order to survive and develop. The essay also mentions the important role of bees in the ecological environment, and also explains the interaction between humans and animals.
Taken together, these terms reflect the importance of understanding ecological conservation and the interrelationships between organisms.
I'm sorry I don't understand, but can you elaborate on that?

The text bee is from the work "Insects", "Bee" is an article written by Fabre, a famous French entomologist and scientist, known as "the Homer of the Sitankunchailu Insect World" and "Virgil of the Insect World", which is deeply appreciated and loved by the Suizi Provençal poet Mistral.
Insects, also known as "The World of Insects", "Insect Story", "Entomological Notes" or "The Story of Insects", is a long biological work written by the French entomologist and writer Jean-Henri Casimir Fabre, with a total of ten volumes.

"The Bees" is an essay written by Fabre from his work "Insects", and the article writes in the first person about an experiment he has done, that is, to confirm whether bees have the ability to identify directions, reflecting the author's rigorous scientific attitude and realistic style.
The description of the text reflects the author's rigorous scientific style. The author's rigorous style is reflected in the fact that at the beginning of the text, the author uses the word "listening".
What I have heard is not necessarily true and reliable, so this has not only become the reason for "I" to conduct experiments, but also reflects "I" do not believe in blindly following the scientific attitude of seeking truth.
-
Fabre's spirit of serious exploration and rigorous scientific attitude. This text mainly writes: This text mainly writes that "I" heard that bees have the ability to discern directions and want to do an experiment; Then write about the process of "I" experimentation.
Then write about the observations and guesses on the way and the results of the experiments on the way of "I". Finally write the conclusion: "I" yet.
Unexplainable. Why bees have the ability to recognize directions.
-
In this way, seventeen of the twenty bees did not lose their way and returned home without error. Although they flew against the wind and saw some unfamiliar sights along the way, they did fly back.
What does it really mean.
Explanation: Definitely, faithfully.
The implication in the article is that the marked bees did recognize their way and flew back.
Was my answer helpful?
-
Faithful, true.
It's that the bees really flew back.
