In the book Dust Travels, what are the three places where Dust goes to travel?

Went to the fields and mountains, over the ocean, to the city streets.

The central idea of "Dust Travel":

The Journey of the Dust Part 3: Think Like a Mountain, Fly Faster Than Sound, Tomorrow's Sun City. It mainly talks about environmental protection, high-tech and imagination of future science and technology.

This book not only inspires young readers to examine the natural environment and advocate environmental protection, but also stimulates young people's interest and confidence in future exploration, which is very educational.

Dusty trips go outdoors, indoors in the suburbs of cities, flatlands, mountains, deserts, oceans.

What are the three sections of the dust travel:The first part is the autobiography of the fungus. This part has been written in the first person by the fungus, and the full text writes how the fungus defeats the human body step by step:

Slipping from the respiratory tract into the lungs, and then from the lungs to the breast peak, leaving the breast peak and sliding near the esophagus, and excreting from the intestinal cavity, the journey is over, but if it wins by chance, one side will dominate! What I liked the most was his experience at the breast peak: it was the first bacteria to come to the mouth of a newborn, and he was lonely in this body, without his siblings, with no one to fight with him.

There is one place he describes very specifically: climbing in from the nipple peak, there is a shrunken empty sac, where breast milk can be produced, and it is very fond of breast milk, because there are small milk balls and many treasures.

Part II, Bacteria and Humans. In this part, my favorite part is the clear water and turbid water, which made me understand a lot of knowledge that I don't usually know, such as: the river water has the most bacteria, because it has its own water bacteria, and the bacteria in the land, and the groundwater bacteria are the least, I also know that the lake water has fewer bacteria than the river water, although the water in the lake looks green and dirty, but it is cleaner compared to the river water!

How amazing, and because of the development of science and technology, a kind of sterile water is also used in chemical work, which is the purest water now. But this is very difficult to make, very precious and rare, so it is not often seen in daily life.

The third part of the immortal spirit of the cell, in this part, my favorite is the paragraph about coarse grains and fine grains, the article tells us that coarse grains are more nutritious than fine grains in the way of questions and answers, and they will be more delicious than fine grains under a little processing, easier to digest, and the price of coarse grains is lower than fine grains, which saves a little food money can buy non-staple foods (vegetables and meat) so that you can supplement more nutrients. The article also tells us which vitamins are deficient in the body and which symptoms are prone to, it seems that vitamin supplementation is a very important thing!

The author of "The Journey of Dust" is Gao Shiqi, a modern microbiologist and popular science writer.

Born in 1905, Coats' grandfather went to the United States as a young man to study bacteriology. In 1928, at the age of 23, Coats contracted the encephalitis virus during an experiment. His condition gradually deteriorated, leaving him paralyzed.

His head was tilted to the left, his speech was slurred, his eyes were straight, his limbs could not move, and it was difficult to even drink water.

But he lived tenaciously, and for decades, he wrote more than a million words of works for us children and teenagers, such as "Our Soil Mother", "The Work of the Sun", and "Uncle Time". When he wrote, he first laboriously dictated and asked others to record it. Because he couldn't speak clearly, it was difficult for others to understand, so he had to repeat it several times.

After half a day, he often only memorized one or two hundred words, but he was so tired that he was sweating profusely. Even so, he persevered tenaciously. "Dusty Travel" was also written in such a situation.

Introduction:

The Journey of Dust (aka "Adventures in the Bacterial World") is divided into three parts: science jokes, science sketches, and science fairy tales.

The book is a collection of Chinese and foreign popular science works, and contains knowledge in the beautiful stories, with moderate length, beautiful words, vivid and interesting. It is an interesting, aesthetic and intelligent book to help children discover the beauty of science through reading, which can better satisfy children's curiosity and curiosity, as well as the imagination of beautiful words.

The author of "The Journey of the Dust" is Gao Shiqi. Gao Shiqi is a famous scientist, popular science writer and social activist in China, and a pioneer and founder of China's popular science cause. Over the past half century, he has written millions of words of scientific sketches, scientific fairy tales and various forms of popular science articles while he was paralyzed, guiding groups of young people to embark on the road of science, and is affectionately known as "Grandpa Gaoshiqi".

Character achievementsGao Shiqi was diligent and studious all his life, well-read, meticulously researched, and diligent in writing. His works are included in the "Siku Quanshu", including "The End of the Chronicle of the Left Chuan", "The Examination of Place Names in the Spring and Autumn Period", and "Supplement to the Three-Body Tang Poems"; Included in the "Four Inventory Catalogue" are "Tianlu Zhiyu", "Saibei Small Banknote" and other five parts. In addition, there are more than a dozen works such as "Reading Notes", "Yuan Xiji", and "Jingjin Manuscripts".

In this extremely difficult situation in the previous spring, he resolutely returned to China, ran around for the medical cause of the motherland, and wrote a large number of popular science articles, "Dust Travel" is one of them.

Gao Shiqi has devoted his life to the popularization of science and the creation of children's books, and his representative works include "The Autobiography of the Fungus", "The Plague is Coming", "The Aspects of Disease", etc., leading readers to easily enter the world of science and unveiling the mystery of science for us.

A wonderful microbial world.

In the American text, you will be intoxicated and unable to release the volume; In **, you will be intoxicated, immersed in it; In technology, you'll be amazed and amazed. And in the world of microorganisms, it often leaves you stunned and full of novelty. Recently, I read a book called "The Journey of Dust", which gave me more awareness and understanding of microorganisms.

Now, let me take you on a journey to the microbial world!

Microorganisms - bacteria, can be regarded as "the earth", except for the great desert and the top of the snow-capped mountains, there are traces of it in every corner of the earth. Sometimes it's a bad guy, wreaking havoc in the airways and doing evil in the nose and throat. Some "little bacterial bullies" can also cause some diseases, which is worrying.

Bacteria are really "bacteria" as the name suggests. At the top of the small, there are hundreds of bacteria floating in the dust visible to the naked eye. The top is light, so light that millions of bacteria hanging under the feet of flies don't feel heavy.

I can't help but be amazed! It is really ubiquitous, all the time, on the peel of melons and fruits, in rivers, lakes and seas, and ...... on people and animalsTherefore, we should develop good hygiene habits, wash hands frequently, change clothes frequently, and ensure our own hygiene and safety.

It is sometimes very bad and can damage the human body, so we have to scrub the wound with alcohol and rinse it with water after the injury to ensure that it is not invaded by bacteria. And how much is it so lovely sometimes, how can it be so common to make wine, bread, and leather? Didn't he participate in the soil revolution?

I used to think that bacteria are only bad, not good, which is really a biased idea.

This book is like a fountain of sweetness, nourishing me; Like a lighthouse, guiding me; Like a ladder, help me. The world of microbes is amazing! I gained a lot from this microbial trip.
