Reading Notes on the Adventures of the Bacterium World 1 After the sixth grade, we have four science classes every week. The first unit mainly talks about the knowledge of bacteria. So, my mother bought me a copy of "Adventures in the Bacterial World" written by Gao Shiqi, which made me swim proudly in the ocean of science.
This book shows me the fantastic scene of bacterial life in the first person. Not only wrote the life habits of bacteria, how to harm people's health, but also wrote how to benefit human life. I can't help but admire that bacteria can do so many things although they are small.
Bacteria can hurt people. When we are scratched, bacteria will have a chance to sneak into the human body, and we will fester and fester. Bacteria invade our bodies from food, and we will have symptoms such as cough, fever and chest tightness. In fact, they are all bacteria in the dark. "The disease comes from the mouth, and the disaster comes from the mouth." Only by developing good hygiene habits can we not be attacked by bacteria.
People always think that bacteria are heinous villains, but from this book, I learned the beneficial side of bacteria. Yeast can be used to make wine, and yogurt has the credit of lactic acid bacteria. As long as it is biological, no matter what, it is interdependent. Bacteria can change soil properties and supplement soil raw materials. "Falling red is not heartless, but turning into spring mud is more protective of flowers." In fact, it is with the silent cultivation of bacteria that the creatures on earth get the nutrition they need.
Bacteria, like humans, are good and bad. In our daily life and study, we should also learn to foster strengths and avoid weaknesses, give full play to our strengths, make ourselves more perfect, and make ourselves by going up one flight of stairs!
Adventures in the Bacterial World popularized the scientific knowledge of related bacteria, and also told me that we should fully understand everything and let them give full play to their strengths for the benefit of mankind and the world! We should also foster strengths and avoid weaknesses in our study and work!
Adventures in the Bacterial World 2 When I opened the book Adventures in the Bacterial World, the naughty, pitiful, cruel and sad bacteria told me all its secrets in its beautiful language.
Following the fungus, I was lucky enough to visit their little world and learn about their food, clothing, housing and transportation. Although they are very small, people often ignore them, but they are everywhere, and their fighting capacity is not weaker than anything else. The seemingly insignificant bacteria can not only destroy the human immune system, but also lead their brothers and sisters to quietly kill a fresh life. Of course, we don't have to talk about bacteria. Bacteria are a "double-edged sword". Although they can bring diseases, many bacteria are also good friends of human beings. They can help us cook all kinds of food. They can ferment milk into delicious yogurt, grape juice into delicious wine and ordinary dough into delicious bread. ...
"Know yourself and know yourself, and you will win every battle." Only by mastering the characteristics and preferences of bacteria can we seek advantages and avoid disadvantages, so that bacteria can better serve human beings and avoid their harm. In daily life, we should form good habits, wash our hands frequently, exercise more, maintain a good attitude, put an end to "three no foods", avoid eating expired foods, disinfect common items and wear masks when going out. ...
After reading the book "Adventures in the Bacterial World", I benefited a lot. As long as you do a good job of protection and let bacteria take advantage of it, you can have a healthy body and meet the challenges of life.
Adventure Notes in the Bacterial World 3 Since reading Grandpa Gao Shiqi's? Adventures in the bacterial world? I fell in love with this book. This book introduces us to the life of various microorganisms in the vast world, which is colorful, small and great.
In life, my mother often tells us to wash our hands frequently and pay attention to hygiene. Because there are many harmful bacteria around us, such as mycobacterium tuberculosis, streptococcus, etc., which can cause large and small symptoms and make our bodies uncomfortable. But bacteria also have a lovely side, such as yeast and lactic acid bacteria, which are very beneficial to us. Without yeast, there would be no bread, and without lactic acid bacteria, there would be no yogurt.
A tiny bacterium is a laborer of the soil. Every gram of soil contains about 3 million to 200 million bacteria. After death, organisms will be classified into soil, and their protein and cellulose will be decomposed by bacteria. Because bacteria work day and night, our home is so beautiful.
A tiny bacterium is also the prosperity of the earth. I especially envy the "separation" of bacteria. When a bacterium is full of food and drink, it thinks it is too fat and too heavy. So using "technique" becomes "two halves". It can be divided into dozens of times a day at most, and it has flourished since then, just as the book says: "The more you are born, the closer you are to death."
I think, when I grow up, I want to be a microbiologist, find out more bacteria, extract substances that are beneficial to us human beings, and let more bacteria become good helpers of human beings.
The Adventures of Bacteria World Reading Notes 4 Bacteria is a word that everyone is familiar with. But no one has really seen the world of bacteria. The adventure in the bacterial world made up for this regret. It made me feel the true face of the bacterial world.
Adventure in the Bacterial World is the work of Gao Shiqi. It tells the basic necessities of life and some living conditions of bacteria from the perspective of bacteria. This book is very interesting and attracts me to read it like a fairy tale; It is also like a popular science book, which has taught me about bacteria.
I learned from this book that bacteria are closely related to our lives. For example, in the army, bacteria are regarded as potentially dangerous weapons. As far as food is concerned, the yogurt, beer, bread, cakes and other foods we drink are all "fermented" by bacteria. In life, microorganisms such as bacteria can decompose the corpses of some animals or people, thus achieving the purpose of beautifying the environment.
From this book, I also learned some methods to prevent virus infection or bacterial invasion, such as: spitting phlegm into a handkerchief or spittoon can effectively avoid bacterial infection; Washing hands before and after meals, not eating three kinds of foods, not eating expired foods, not eating leftovers and other foods that are often infested with bacteria can prevent bacterial diseases from entering the mouth.
Bacteria have both advantages and disadvantages to human body. We should know them objectively, accurately and comprehensively, so that we can not only avoid harm, but also make them better serve mankind.
When it comes to bacteria, people's first impression is often dirty, because we are sick. Dachuan is related to bacteria, such as colds, loose bowels and wound infections. ...
After reading "Adventures in the Bacterial World", you will find that bacteria are not so terrible. It turns out that bacteria is one of the earliest creatures on the earth, and we humans can't live without bacteria. Some of them live in water, others live in soil, human beings or animals and plants, each with its own characteristics and skills.
Some bacteria have made great contributions to us, such as lactobacillus, fermenting bacteria and so on; Some of them will do harm to our health, such as Streptococcus pneumoniae and bacteria in the mouth. Through this book, I know for the first time what it's like to be sick. Most of the time, they are at peace with our bodies, and only when the body's immunity drops will they cause diseases.
With the progress of science and technology, we humans have begun to master the characteristics of bacteria, such as using disinfectants to kill pathogenic bacteria, preventing infectious diseases, or using beneficial bacteria such as lactic acid bacteria to serve people.
The Adventures of the Bacterial World let me know how amazing the bacterial world is. It is not only the enemy of human beings and animals, but also an indispensable part of nature. There will be more scientific mysteries waiting for us to uncover in the future!
