What is the impression of reading the name of the trip of the dust?

I couldn't wait to open the book and read it to the end, and then I realized that dust was so wonderful. They may be small and small, but they are ubiquitous, drifting with the turbulence of the air and moving around the world with the direction of the wind. They are like Ultraman, appearing in every corner of the world.

They are even more powerful than Sun Wukong, they can fly into the sky and the earth, and they are everywhere. The dust is invisible, and it is only when the sun's rays shine into the room that countless dusts can be seen dancing happily in the air.

There's also smaller dust, which is smaller than bacteria and you can't necessarily see it with a microscope. A lot of dust is very harmful to our human life. They not only destroy our fresh air, but also stain our clothes, houses, furniture and**, posing a great threat to us.

It will sneak into our nostrils and penetrate our lungs while we are breathing, so we will often feel nostrils, lung inflammation, coughing and other infectious diseases. What should we do in the face of these hazards? In order to resist the attack of dust, I feel that we must wear masks, wash our hands frequently, bathe frequently, clean frequently, and keep the room clean and the air smooth.

If we want to have a healthy body, we have to do these things well. There are many kinds of dust that are harmful to human life. Ever since organics have joined the ranks of dust, you see, the danger has become even more serious.

It stains our air, it stains our houses, and sometimes they destroy our industrial products and turn them into waste. Moreover, the most serious thing is that dust is the destroyer of the respiratory duct, he they can make the nostrils blocked, the trachea inflamed, and the lungs injured, which can cause colds, epidemics, pneumonia and other infectious diseases.

Everyone has their own name.

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 a potato macro that 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 in the dress.

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 now, a kind of sterile water is used in the 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 the Dust (also known as "The Adventure of the Bacterial World") is divided into three parts: science talks, science sketches and science fairy tales, which use easy-to-understand language to explain the profound scientific knowledge vividly and clearly, completely remove the veil of scientific mystery, and lead young people to easily enter the magical world of science.

The author is Gao Shiqi. "Journey in the Dust" (also known as "Adventures in the Bacterial World") is a collection of works by the famous popular science writer Gao Shiqi. The book is divided into three parts: science talks, science sketches and science fairy tales, which use easy-to-understand language to explain the profound scientific knowledge vividly and clearly, completely remove the veil of scientific mystery, and lead young people to easily enter the magical world of science.

Gao Shiqi, formerly known as Gao Shi, is a famous Chinese scientist, popular science writer and social activist, a master of popular science in China, a pioneer and founder of popular science, and graduated from the University of Chicago Medical Graduate School in 1930.

Over the past half century, Coats has written millions of words of scientific sketches, science fairy tales and various forms of popular science articles while he was paralyzed, guiding batches of young people to embark on the road of science.
