Thoughts on dust travel

After reading a book carefully, everyone must have a lot of feelings about life or things, so it is necessary to write a book review! So how should I write my thoughts after reading? The following are my thoughts on dust travel, which I helped you sort out. I hope it helps you.

When it comes to bacteria, people's first impression is often dirty, because most of our diseases are related to bacteria. However, when I saw Dust Travel, I found that bacteria are actually not as terrible as everyone thought.

After reading the article, I realized that bacteria are one of the earliest creatures on the earth and are indispensable to human beings. According to the article, some of them (bacteria) live in water and some live in soil. There are good and bad bacteria, such as lactic acid bacteria, yeast and mold, which have made great contributions to us!

After reading the whole book, I can't help but have many questions. The article said that the author wrote it on behalf of bacteria, but the words it wrote were invisible to ants and could not even hear what flies said. How does the author know the sound of bacteria? Why do bacteria have immortal spirits? Why are bacteria afraid of fire? ..... These problems, like rice in a rice jar, are endless. I think bacteria may be afraid that the flame is too hot to burn themselves, so they should never touch the flame for a lifetime. Bacteria are terrible. They give us physical problems. When you are sick, you need injections, infusions, and drugs that children don't like the most. But all the bacteria described by Grandpa Gao Shiqi are lovely. The author thinks of himself as a bacterium, and his bold imagination should be to make people change their views on bacteria and make people no longer afraid of bacteria. Now I'm not afraid of bacteria. Only some bacteria can make us sick. There is no need to make a mountain out of a molehill Just silently treat them as good friends. Of course, pay attention to personal hygiene and protection, and don't let bad bacteria take advantage of it. In the future, I can greet you loudly, my little transparent bad friend.

Bacteria, bacteria, I have regarded you as a good friend, so don't hurt me! My germ friend!

Reflections on Dust Travel 2 Today, I finished reading the book Dust Travel.

There are many chapters in Dust Journey, only one of which is about Dust Journey. A grain of dust is invisible to the naked eye. It is much smaller than the smallest bacteria and can only be seen with a microscope. Dust is a tireless traveler on the earth, and they drift with the turbulence of the air. The air around us, from indoor to outdoor, from flat to high mountains, from hot desert to blue ocean … almost all have their traces.

Dust is also the maker of white clouds and raindrops. They will help the moisture in the air condense into clouds and raindrops. Without them, there would be no beautiful white clouds roaming in the sky and no light rain and heavy rain. So where did the dust come from? Some dust comes from rock fragments in the mountains, some from dry soil dust in the fields, and some cosmic dust from interstellar space ... these are all natural dust.

There are also artificial dust, mainly chimneys and smoke from cement plants, metallurgical plants and sawmills ... In addition to these inorganic dust, there are organic dust, which comes from the animal kingdom and the plant kingdom, such as seeds, pollen and flower buds.

Dust is also harmful to human beings. They will not only pollute our air, but also pollute our houses, windows and furniture ... and wear the smooth parts of the machine. These are small things. Dust is the destroyer of respiratory tract, which can block nostrils, inflame trachea and injure lungs, thus causing infectious diseases such as cold, influenza and pneumonia. In addition, metal dust can poison people, pollen dust can cause asthma, and finally, dust can cause explosion, which must be prevented. There are too many stories about dust!

In addition to the story of dust travel, there are many stories, such as the story of mirror, hot travel, material encounter and other interesting stories. Come and explore the scientific world in dusty travel with me!

After reading the dust, books are the ladder of human progress, and a good book is very important for our growth and success. I recently read the book "Dust Travel" and benefited a lot.

This is a group of travelers who travel around the world. "They are very thin, very small, but they can fly without wings. When people see them, they wave and close the doors and windows. " What is this? By the way, they are ubiquitous, ubiquitous dust. The protagonist of Dust Travel is dust, and the author has given them a very kind and lovely nickname "Juner". This name really doesn't accord with our consistent impression of dust. You might think that we should give dust a disgusting and terrible name. But after reading the book A Journey to Dust, I followed the author to think from a different angle and see the world from the perspective of dust. When human beings were forced to face "Juner" with a microscope, I saw that "Juner" was like a group of refugees fleeing everywhere, desperate and helpless. Later, people regarded "germs" as "killers" who brought disasters and spread diseases, and suffered various kinds of "torture" from human beings. Some "germs" were burned to ashes, some were surrounded by water and fell into the sea, and some were imprisoned in various containers forever, and they could no longer roam freely.

I admire the imagination of the author Yang Jiujun, who is unconstrained and unconstrained. His brushwork is to look at the world from the perspective of dust, and the protagonist in the book is a tenacious "germ". He successfully escaped from all kinds of "poisonous hands" of human beings, vividly described the real life of "I" as dust in the first person, and vividly told the joys and sorrows of "I". As a reader, I always immerse myself in the dusty world, overcome difficulties and travel and play with my dusty friends. ...

Dust travel brought me into a strange and wonderful unknown world, which aroused my great interest in exploring the dust world. The ocean of science is boundless. I will study hard in the spirit of "elaborate and diligent" and learn endless knowledge from books.

Thinking about Dust Travel 4 Recently, I read a very interesting book called Dust Travel. This book talks about soil, cells, heat and so on, all of which are of interest to me. When I first saw the title of the book, I felt as if I had no desire to read on. But since I started reading this book, I have completely stopped. I can't wait to finish reading it in one day.

I like the sentence in the book "Dust is a tireless traveler on the earth". It turns out that being a speck has so many advantages that you can travel everywhere. But if you think about it carefully, it doesn't seem very good either, because you can only go with the flow and not make your own decisions. It's like I'm reading this book. If I can't turn to the next page, it must feel terrible.

I like the story about mirrors in the book best, which tells the changes of mirrors from ancient times to the present. At first, the ancients used bronze mirrors, which were not very clear and easily rusted when exposed to water. This kind of mirror is definitely inconvenient to use. Mirrors nowadays are all real cows. Some mirrors can make people thinner, some mirrors can make people taller, and some can make the upper body fat and the lower body long. Now the mirrors are really varied and the craftsmanship is amazing!

I also like the chapter about bacteria and people. More precisely, my favorite is The Story of Ironmaking. At that time, it was terrible to see people without iron. It turns out that iron everywhere around us is so important! Think about it, too. We need iron everywhere in our lives, so iron must be very important! It seems that I should cherish the things around me, but they are not ordinary.

If iron is important, then electricity is equally important to us. Because I think if there is no electricity, then the machines around us will not work normally. Then the world turned black, and just thinking about such a scene scared me.

Dust Travel is really a rare good book, which fascinates me deeply. The author also uses many good words and sentences in the book, which makes people feel relaxed and interesting when reading, rather than boring. This author is too powerful.

After looking at the dust, bacteria are tiny and light microorganisms, so small that we need a microscope to observe the lovely "elf" that you simply don't feel its existence. For example, there are tens of millions of bacteria hanging on each slender leg of a fly, but the fly flies freely without any influence or feeling. Besides, the bacteria in our hands can reach billions or even hundreds of billions every day, but do we think it has weight? No; Did we see it with the naked eye? No; When can we feel its existence again? There are fruits and vegetables that we eat three times a day, rivers and lakes that we can see with our naked eyes, and even a tiny drop of rain falling from the sky, which will be covered with countless bacteria ... So, we should develop good hygiene habits.

In life, it is a pleasure to "struggle" with dust. After school, I cleaned my desk before I went home. When nobody was there at night, these naughty little guys flew in from all directions, used the desk as an entertainment place, sang songs and danced street dance on it ... Finally, when I was tired, I used the table as a bed and slept and dreamed ... The next day, I gently wiped my beloved table with a wet towel. These guys who don't like bathing, with black heads and gray faces, have wiped my wet wipes as white as snow.

Life is full of fun with bacteria. When my mother and I were making steamed bread together, it was lovely to watch the flour grow into fat steamed chicken under the fermentation of bacteria. When making yogurt, under the action of bacteria, you can drink a mouthful of sour and sweet yogurt, which tastes delicious; Under the brewing of bacteria, my mother is drunk and happy ... bacteria have added a lot of fun to our lives.

Coming out of the dusty journey, I have gained a lot; I made a special "trip" with a "dust trip", and I got to know lovely bacteria; And "Dust Travel" embraced each other deeply, and got a warm baptism in the embrace of bacteria.

Thinking about Dust Travel 6 After watching Dust Travel this holiday, I have many ideas in my heart and want to share them with you.

The author of this book is Grandpa Gao Shiqi. This book tells how dust is produced and its harm to society and human beings through concise language. Finally, human beings use dust to protect the environment.

As we all know, Dust is a traveler who once traveled around the world at an altitude of 80,000 meters on the ground! This height is more than six times higher than Mount Everest! And they are everywhere, almost all over the world. Why are they almost? Because only laboratories can create dust-free spaces, they can't arrive safely every time they travel.

Once, the dust was caught by a scientist. After being caught, the scientist actually blocked the bottle mouth with a piece of cotton, but Dust also ate and drank every day. In the eyes of dust, this cotton is like the gossip in The Romance of Three Kingdoms and the maze in The Romance of Gods. If you can't find an exit, the scientist will turn your face if you turn your face. Once, scientists used fire to burn off the bacteria and germs produced inside. You know, fire and high temperature are what those things are most afraid of, which makes me feel bad. Although some pathologists now blame dust, sometimes this is not the case. Finally, people have developed something that can use dust to protect the environment. Since then, human beings have made the earth more and more beautiful.

Through this book, I understand that we should develop good hygiene habits from childhood, protect the environment and make our home more and more beautiful.

Reflections on Dust Travel 7 When I picked up the book Dust Travel, I was very curious. Dust? Dust? Can dust travel?

I can't wait to read the book before I know that the dust is so wonderful. Although they are small, they are everywhere, drifting with the turbulence of the air and traveling around the world in the direction of the wind. They are really outstanding travelers. They appear in every corner of the world like Altman. They are even better than the Monkey King. They can fly to the sky, or they can hide in the ground, pervasive.

Small dust is invisible. Only when the sun shines into the room can you see countless dust dancing happily in the air. There are smaller dust, smaller than bacteria, which you may not see with a microscope.

A lot of dust is very harmful to our human life. They not only destroy our fresh air, but also pollute our clothes, houses, furniture and skin, posing a great threat to us. It will sneak into our nostrils and penetrate into our lungs when we breathe, so we often feel infectious diseases such as stuffy nostrils, lung inflammation and cough.

What should we do in the face of these hazards? In order to resist the invasion of dust, I think we must wear a mask, wash our hands frequently, take a bath frequently, clean up frequently, and keep the room clean and the air unobstructed. Does it feel like a war virus? Yes, if we want to have a healthy body, we must do these things well.

Ok, that's all for today. If you want to know more about dust, then I suggest you also watch Dust Travel.

After reading the Travel of Dust, I have been reading the book Travel of Dust, which has given me a special understanding of the micro-world. I know that dust has two sides.

After reading this book, I benefited a lot and learned that dust is a never-ending passer-by on earth. It is floating around with the air, everywhere, and it has its whereabouts everywhere. Dust is big and small, so it can be seen by naked eyes, but not by microscope. Dust includes smoke from chimneys and organic dust from living things. This book tells us that there are still bacteria and viruses in the dust, and many kinds of dust are dangerous to human life. Since the organic matter joined the dust team, you see this kind of harm is more serious. What harm does so much dust do to people's lives? It will pollute our air and house. Sometimes they will destroy our industrial products and turn them into waste products. And the most serious thing is that dust is the' destroyer' of the respiratory pipeline, which will clog the nostrils, inflame the trachea and hurt the lungs. Thereby causing infectious diseases such as colds, flu and pneumonia. Dust is the most dangerous enemy of our health, which is harmful to human life. We should try our best to control it.

When I finished reading this book, I thought of the village where I grew up. There is a clear river in the village, which is covered with green trees. We should protect these environments from childhood and keep them spotless. My campus is also a beautiful place. We can't litter or spit on campus. We should always clean the campus and classrooms and keep them clean and tidy. I have developed a good habit of planting trees since I was a child. I should also pay attention to personal hygiene, wash my hands frequently, wear a mask when necessary, care for and supervise the campus environment, prohibit uncivilized behavior, and strive to control dust and garbage to make our city and campus more beautiful.

By reading this book, I know that everything has two sides. Let's join hands, seek advantages and avoid disadvantages, and green our home!

Thinking about Dust Travel 9 During the winter vacation, I read the book Dust Travel, which tells that dust is everywhere on the earth. It will float around in the direction of the wind, and it will fall everywhere.

This book introduces the types, shapes, sizes and sources of dust in detail. Some dust is visible to the naked eye, and dust can be seen everywhere in life, such as dust raised by cars passing by on the road or smoke from factory chimneys. Others are so small that they can only be seen through a microscope.

Dust is the enemy of human health, which will cause environmental pollution and affect our lives. Dust exists in our clothes, faces and places where we live, and even leads to respiratory infections and other diseases.

Because of the great harm of dust, people are trying their best to control the spread of dust. Once my father and I went to the construction site and saw a row of sprinklers installed neatly and regularly on the walls around the construction site, and a large pool was dug at the door of the construction site. The pool is full of water, so every car going in and out of the construction site has to go through the pool before it can get on the road. Just when I was wondering, my father told me that this pool was specially used to wash car tires. Because there was a lot of mud on the wheels, car tires had to be washed before they could go on the road, in order to avoid secondary pollution to the environment. Sprinklers on the fence prevent dust from floating around the construction site. Sprinklers atomize water and contact with dust in the air, so dust will not fly around.

Therefore, we should care for the environment and protect it, and strive to control dust so that we can breathe clean and fresh air every day.

Reflections on Dust Travel 10 During the summer vacation, I reread the book Dust Travel, a science book written by Gao Shiqi, which is very interesting.

This book mainly writes the self-report of bacteria. The hero is "Juner", a bacterium. It mainly eats rotten and smelly food, and some bacteria also eat blood and protein, because they need protein in their bodies to breed the next generation. There are two main contents in the book. On the one hand, it is a "dusty journey", mainly Gao Shiqi's "scientific anecdote" article; On the other hand, it is "bacteria and people", mainly Gao Shiqi's "scientific sketch" article. Scientific anecdotes introduce interesting scientific phenomena and principles, such as dust travel. Scientific sketch includes the food, clothing, housing, transportation and morphology of bacteria, as well as the relationship with human beings and soil.

The travel of dust mainly conveys that dust is everywhere and never stops. It has a good side, it can make rain and clouds. Without dust, there will be no rain and clouds, let alone heavy rain and light rain, and the temperature will not drop in the future. Of course, it also has its shortcomings, which will pollute houses, walls, furniture, clothes and human skin. Dust is also the destroyer of the respiratory tract, which will block the nostrils, inflame the trachea and hurt the pulse, thus infecting the disease.

Therefore, dust must be supervised by human beings and cannot fly around. We should use scientific means, give full play to its advantages, use it, avoid its shortcomings as much as possible, and make the earth we live in more beautiful and harmonious!

There is a lot of scientific knowledge in this book that can be applied to our lives. This is a science book especially worth reading. I hope everyone will finish reading it.

During the summer vacation, I read a book "Dust Travel" by Gao Shiqi. Grandpa Gao Shiqi vividly narrated profound and mysterious scientific knowledge in easy-to-understand language, and easily led me into the scientific world. After reading this book, I understand many magical scientific phenomena, The Secret Behind, among which I am deeply impressed by the magical function of "laughter". Do you want to know? Listen, I'll tell you slowly.

Laughter is a sign of a good mood and is good for health. Laughter is a complex nerve reflex. When a joke from outside becomes a signal, it is introduced into the cerebral cortex through the senses. When the cerebral cortex receives the signal, it will immediately direct the movement of muscles or some muscles.

Laughing on the chest can expand the chest muscles, strengthen the movement of the lungs, and make people breathe normally. Laughing into the stomach can produce gastric juice in time, help digestion, stimulate appetite and promote human metabolism. Laughter in the heart strengthens blood circulation and makes people rosy and energetic. Laughing all over the body makes people get enough sleep and full of energy while being excited. Laughter can also eliminate excessive muscle tension and prevent pain.

Laughter has so many benefits, but these are often overlooked by us. Many people encounter some unpleasant things in their lives, their smiles gradually disappear and their bodies gradually become unhealthy.

I am also a sunshine boy who loves to laugh. I usually like telling jokes with my classmates. When I encounter difficulties, I will also give myself a smile and tell myself that "everything will be fine". Finally, I really overcome the difficulties. I always believe that people who love to laugh are not bad luck.

Laughter is a healing and healthy friend. Let's smile more!

After reading the dust, 12 When it comes to bacteria, our first reaction is dirty, but is this really the case? The answer is no.

Then why do people think that all bacteria are harmful? Because many of our diseases are caused by bacteria, such as colds, diarrhea and wound infections ... After reading Travel in the Dust, we will find that bacteria are not so terrible, and some bacteria are beneficial to us, or indispensable creatures in life.

It turns out that bacteria are the earliest creatures on the earth, and we humans can't live without bacteria. Some are in water, some are in soil, and some are in people and animals. Although they are small in size, they can do well!

The delicious yogurt we drink and the delicious kimchi we eat all have the shadow of lactic acid bacteria; The role of yeast is to make wine, but this mold can also be used, so yeast can make dough; Mold can also be used to make soy sauce, tofu, yogurt and so on.

Many people think that bacteria are naked. Later, after observation, I realized that they were all wearing a thin layer of clothes. The scientific name is "capsule", which is made of wax. The clothes worn by shepherd's purse, mycobacterium tuberculosis and pneumococcus are particularly delicate and heavy, which is especially easy for us to know.

Now most people know the characteristics of bacteria and how to prevent harmful germs. As soon as germs were discovered, scientists studied ways to deal with them, and immediately took various measures to eliminate germs, such as spraying disinfectants in densely populated places and natural disasters such as fires or earthquakes to prevent infectious diseases, and the high-temperature disinfection method mentioned in the book, which can achieve sterilization by heating food to 100 degrees Celsius.

Of course, we still can't be careless. We must pay attention to prevention, do a good job of personal hygiene, and don't give bacteria an opportunity.
