The book "One Hundred Thousand Whys" is my lifelong friend. It has taught me a lot of knowledge and is my treasure book of knowledge. I had a lot of thoughts after reading it.
Once, I was reading the purpose of a cat’s whiskers in One Hundred Thousand Whys. I thought: Cat’s whiskers still have a role! How interesting. I read on. It turns out that a cat's whiskers are the cat's ruler. If there is a small hole in front of it, the cat only needs to use its whiskers to measure it to know whether it can pass through. It seems that a small, inconspicuous thing can have a great effect.
Another time, I was reading "Whose son is the swarm of tadpole babies in the pond?" I thought: Aren't tadpoles just the children of frogs? All children in kindergarten know this. Turns out I got the answer wrong. In fact, they are toad's children, because although their children are both tadpoles, frog's children like to act alone, but toad's children like to act in groups. This is the difference between toad and frog's children.
Also, am I reading "Do figs bloom?" I thought again: As the name suggests, figs are fruits without flowers. Turns out I was wrong again (so embarrassing). Figs actually bloom, but the flowers are very small, so don’t believe the rumor that figs have no flowers.
The knowledge discussed in "One Hundred Thousand Whys" cannot be learned in textbooks. It not only enriches our extracurricular knowledge, but also allows us to see the world from a broader perspective. My thoughts after reading "One Hundred Thousand Whys" 400 words 2
By reading "One Hundred Thousand Whys", I understood a lot of scientific knowledge.
After reading this book, I learned a lot of knowledge, such as, why do clouds not fall? Because clouds and fog are the same, they are water vapor rising from the ground. However, clouds are high in the sky, while fog is lower near the ground. Sometimes the fog is lifted up and turns into clouds. In summer, the ground is scorched by the sun, and the air on the ground is heated and lightened, so it rises into the sky. As the hot air rises, it slowly cools down and condenses into many small water droplets, forming clouds one by one. Because this kind of small water droplet is very light, it is easy for the rising air to hold it, so it floats in the sky. In addition, the cold air and hot air hold it up into the sky, turning it into a cloud; sometimes, it collides with the flowing moist air. When it reaches mountains and plateaus, it will also be forced to rise, forming clouds and fog. And why does it snow? Because in the clouds higher in the sky, there are only water droplets and ice crystals. When the updraft cannot support those clouds, those small water droplets and ice crystals will fall toward the ground. It's just that in spring, summer and autumn, the temperature on and near the ground is relatively high, so those ice crystals melt in mid-air. When a large number of ice crystals in the clouds fall to the ground, they will not melt and fall directly to the ground. This is snow, books are the ocean of knowledge, books let us understand many truths.
A famous saying goes well: "Books are the ladder of human progress." This sentence tells us that only by studying seriously can we get into a good university and our knowledge will become richer and richer. Thoughts after reading "One Hundred Thousand Whys" 400 words 3
"One Hundred Thousand Whys" is a popular science book with a lot of knowledge and science. The knowledge in it is all-encompassing, ranging from astronomy to geography. Science, geography, animals, plants. There are many scientific questions that can be answered in "One Hundred Thousand Whys".
In the past, every time it rained, I would see beautiful rainbows in the sky. Before I read "One Hundred Thousand Whys", I didn't know how rainbows were formed. After reading " After "One Hundred Thousand Whys", I learned: Rainbows are actually formed by small water droplets floating in the air reflecting sunlight. This is because the water droplets are larger during thunderstorms. Often after a burst of rain, it clears up quickly, and the water droplets reflect the sun's rays in the air, forming a rainbow.
After reading "One Hundred Thousand Whys", I also know how rain and snow are formed. Due to the sunlight, water turns into water vapor and rises into the sky, forming clouds in the sky. When the clouds are filled with water, rain will come, which forms rain; snow is formed because: water vapor meets the sky in the sky. The cold air condenses into little freezing points, which fall and turn into snow.
After reading "One Hundred Thousand Whys", I also learned about "Why stones are poisonous", "What is a delta", and "Why does the sand sing"? "One Hundred Thousand Whys" is really a book that can be read a hundred times An endless popular science book! My thoughts after reading "One Hundred Thousand Whys" 400 words 4
Today, I read a book called "One Hundred Thousand Whys". The main content of the book is to answer difficult questions about the human body in medicine. It is presented in the form of questions and answers. The scope of this book is very wide, including not only "medicine", but also "industry", "agriculture", "science" and other aspects of knowledge, so it is called "One Hundred Thousand Whys".
Ah, I flipped through the book with great interest and made a new discovery. For example, when I hiccup, my mother always tells me to drink more water, saying that just drink it and it will be fine. But when I ask her why, she can't give me a reason. But when I saw the book saying "Why you shouldn't drink boiled water when you have hiccups", I was shocked. My mother was wrong! I then looked down and saw that it was easy to choke water into the trachea when burping, alas! My mother was talking nonsense, and she said yes. I told her not to drink water when burping. She said this was what her grandma told her. I showed her the book, and my mother smiled and said, "Ah! It turns out we were all wrong. You are right." I was overjoyed after hearing this.
I became more and more interested. I flipped through the pages, and suddenly I discovered a question that I had never understood, "Why do you have a fever? "Drink more boiled water." Because every time I got sick, my mother would tell me to drink more boiled water. I always disagreed and refused to drink more. After reading a book, I learned that water has the function of regulating body temperature. Drinking more water can also kill bacteria. The toxins produced are diluted. Drinking more water can dilute and take away the harmful substances, preventing them from having the opportunity to do evil! It turns out that water has such great effects, I will definitely take the initiative to drink more water in the future.
After reading this book, I also learned a lot of knowledge, such as "what is acupuncture", "why treatment must rely on the root cause", etc., ah! This book really benefited me a lot!
I must seriously look for another version of "One Hundred Thousand Whys" to make me a knowledgeable person. Thoughts after reading "One Hundred Thousand Whys" 400 words 5
I saw a book called "One Hundred Thousand Whys" for primary school students. The questions in it are very interesting. One of the questions is why some flowers are fragrant and some are not. Is it not fragrant? This question is answered like this.
Generally speaking, the flowers of most plants contain fragrance, but not all flowers contain fragrance. Why do some flowers contain fragrance and others not? First, let’s take a look at the ins and outs of fragrance.
The reason why flowers have fragrance is because they have factories that produce fragrance - oil cells. The product in this factory is fragrant aromatic oil, which can be continuously secreted through oil pipes, and can volatilize with water at normal temperatures, thus turning into gas and emitting an attractive aroma, so it is also called volatile oil. Because various flowers contain different volatile oils, they emit different aromas. The reason why we can smell the fragrance of flowers is because the gas molecules escaping from the volatile oils penetrate into our nostrils. In addition, although there are no oil cells in some flowers, their cells will continue to produce some aromatic oil during the metabolism process.
There are also flowers whose cells cannot produce aromatic oils but contain a type of glycoside. Although the glycoside itself has no aroma, it can still emit aroma when it is decomposed by enzymes.
My thoughts: This book is very interesting. I hope many people will read this book and gain knowledge. My thoughts after reading "One Hundred Thousand Whys" 400 words 6
I read this book with curiosity. This is a book about science. It is also related to mathematics in our lives, but I am very curious and want to read this book. Unfortunately, due to the short time, I only read part of it. In this book, I found the interesting content "Why are all honeycombs hexagonal?" After reading the title, I thought that honeycombs are also round, so why are they all hexagonal? I took the question and read it carefully. While reading, I was reminded of a real beehive in reality. It looks neat from the front or the side, but the hexagonal honeycomb does have a certain scientific nature, and the French scientist "Uralci" measured it in the early 18th century; he told us a rule, that It’s a honeycomb, and the obtuse angle of each rhombus is 109°28′ (pronounced 109 degrees 28 minutes). But is there any secret? Due to the calculation, the result is exactly the same as the angle of the honeycomb, and there is stability, but it is very different from the circle we guessed.
From this reading, I felt that although it was an ordinary thing. It's not unreasonable. All things do have their scientific nature and regularity. Human beings have gained a lot of inspiration from the structure of honeycombs. For example, applying it to the materials used to make aircraft can save materials, reduce the weight of the aircraft, and ensure that the aircraft is strong, heat-insulated, and sound-insulated. The same honeycomb principle is also widely used in architecture! The magical honeycomb condenses the infinite wisdom of nature, which makes me think a lot and makes me feel the greatness of wisdom. We should pay more attention to the laws of all things, and we will explore more rich knowledge and principles.
Only time is the only criterion for testing truth. Thoughts after reading "One Hundred Thousand Whys" 400 words 7
"Books are the ladder of human progress" "One Hundred Thousand Whys" has enriched my knowledge, broadened my horizons, and allowed me to learn a lot Knowledge that cannot be learned from textbooks.
The book "One Hundred Thousand Whys" is very rich in content, including plants, human bodies, animals... Every content in the book made me sleepless and unable to put down the book.
For example: Why do kangaroos have pockets on their abdomens? Because the kangaroo is a mammal, but it is very low-level and cannot allow the fetus to grow in the mother's belly before being born like other mammals, so it has a pocket on its abdomen to raise the baby kangaroo. A baby kangaroo is usually born three days after pregnancy. After birth, it can crawl into the kangaroo mother's pocket, where it feeds and grows. After about seven or eight months, it will go in and out of the bag on its own and move outside. Another example: What is the use of the patterns on the zebra? Zebras have beautiful black and white stripes on their bodies. This is not only to look good, but also to adapt to the environment as a protective color. Because the black and white stripes have different colors, they reflect sunlight and moonlight in different ways, which can damage and The outlines of their bodies are scattered, and it is difficult to separate the zebras from the surrounding shadows. In this way, the chance of the zebras being harmed is greatly reduced. After reading "One Hundred Thousand Whys Essay". And why can ducks swim? Why does the donkey roll on the ground? etc. questions.
The book "One Hundred Thousand Whys" made me realize that the world is so colorful and knowledge is so interesting and interesting; it made me know that science is power and knowledge is wealth. I love "One Hundred Thousand Whys"! Thoughts after reading "One Hundred Thousand Whys" 400 words 8
Whenever I open this book, my heart will always be filled with countless question marks. What is written in it? What's there to see?
This book is a popular science book that tells us all kinds of weird answers from all kinds of trivial matters in life, big and small, and all kinds of strange phenomena.
Not only can he help me open the closed window of knowledge, but he can also help me understand the source of some wonderful phenomena. I didn't know why there were twins in the world before, but now I know: there are two types of normal twins: fraternal twins and identical twins. Fraternal twins are not uncommon, but identical twins are more common. Another type of abnormal twins are conjoined twins. Conjoined twins are different from ordinary people because they are not completely separated when they are born.
Fraternal twins are formed when two different eggs arrive in the fallopian tube and encounter two sperm at almost the same time. Usually only one egg is released from the fallopian tube, so only one child can be born. Since these twins are the result of two separate eggs and sperm, they will not look very similar. Identical twins are embryos that split from one fertilized egg into two independent individuals but originate from the same fertilized egg. Therefore, such twins are genetically identical copies, even to the extent that they are absolutely identical in gender. Although they each have separate umbilical cords, in most cases they share a single placenta. Fraternal twins also have separate umbilical cords and their placentas are separate. An interesting phenomenon is that mothers whose mothers are twins have a higher probability of giving birth to twins. This happens almost more to women in the same family, that is, from mother to daughter. Usually twins are born about three weeks premature.

Today, I read the book "One Hundred Thousand Whys". This book mainly talks about many things. There are animal paradise, botanical garden and scientific and technological inventions, etc.
Let me tell you, there are some animals that you may have never heard of, such as leeches, stick insects, electric eels, sunfish, giant salamanders, and many other things. Let me ask you a question: Why do shrimps and crabs turn red after being cooked? How about it, I don’t know, let me tell you. It’s actually astaxanthin that’s at work. The pigment astaxanthin is not only found in shrimps and crabs, but also in many crustaceans. This pigment is widely distributed in nature. Their chemical name is "ketocarotene" and it is the main component of pigments in animals such as shrimp and crabs. When shrimps and crabs are alive, pigments and proteins are combined together and perform certain physiological functions in the bodies of these animals, so they do not show color. During cooking, due to heat, the pigment protein changes and the pigment is separated, so the shells of shrimp and crabs turn red. Shrimp and crabs also turn red as their proteins change after they die. How about it, am I great? There is a lot of knowledge in the book! There are almost more than 800 pieces of knowledge! ! ! And there are two of them! ! ! This adds up to more than 1,800 pieces of knowledge. I understand: there is knowledge everywhere in life. As long as we have a pair of eyes that can discover, we will discover a lot of scientific knowledge hidden in our lives. Thoughts after reading "One Hundred Thousand Whys" 400 words 10
Although "One Hundred Thousand Whys" (Science and Technology) has all kinds of strange questions, it has scientific and authoritative answers. The knowledge inside covers everything from astronomy to geography, science, plants and animals. Do you want to know the knowledge inside? Come and read my article!
There are many questions in it, and of course there are scientific answers such as: When did the earliest pottery appear? What is the world made of? Why is diamond the hardest? Why is the sun said to be the "mother of mankind"? ... "One Hundred Thousand Whys" also explains why "mathematics" was called "arithmetic" in ancient times? Answer: In ancient my country, "suan" refers to a bamboo calculation instrument, and "suan" refers to the technology of operating this calculation instrument, and also generally refers to all mathematical knowledge related to calculation at that time. Since the 19th century, some Western mathematical disciplines, including algebra, trigonometry, analytic geometry, calculus, etc., have been introduced into my country. Western missionaries mostly use "mathematics", while ancient Chinese arithmetic still uses "arithmetic".
I also know who the "Father of the Automobile" is? German Karl Benz developed the world's first horse-drawn three-wheeled vehicle in 1885. The seat of this car is a bit like the seat on a carriage, and the driver needs to control the direction by turning the tiller. On January 29, 1886, he obtained the world's first automobile invention patent. This day is called the birth day of modern automobiles by most people, and Carl was also hailed as the "Father of the Automobile" by future generations.
"One Hundred Thousand Whys" taught me a lot of knowledge and how colorful the world is. My thoughts after reading "One Hundred Thousand Whys" 400 words 11
After I read the book "One Hundred Thousand Whys" during the vacation, I realized a lot of doubts. It turns out that science is really amazing. I learned knowledge that I couldn't learn in textbooks or in daily life!
What interests me most in "Animals and Plants" is: Why do bees die after stinging people? Because it When it bites people, it also brings out its own internal organs. It's really amazing. The thorns on hedgehogs can be used to collect food. It is also a great defensive weapon!
In the article "Why Food", I learned that when steaming steamed buns in a steamer, which layer will be cooked first, of course the upper layer, because the heat is Those who go up will always stay on the upper level, while those who go downstairs will just pass by, so the upper level will be familiar with it first. I told my mother this little secret, and my mother praised me for reading carefully, and I felt very happy!
From "One Hundred Thousand Whys", I learned that I cannot be picky about food, because children are growing and need a variety of nutrients. Each food contains Different nutrients, so we can absorb nutrients evenly only if we are not picky about food!
This book made me understand a lot of truths and learned a lot of knowledge. Now I won’t bother with any questions. Instead of waiting for my parents to answer me, I went to my second teacher, which was "One Hundred Thousand Whys"! My thoughts on reading "One Hundred Thousand Whys" 400 words 12
I used to go to my sister’s house I got back a set of "One Hundred Thousand Whys" and read it from time to time. Today I started to read it seriously. I read the second volume first because it contains topics that interest me!
The second volume talks about the animal kingdom, the world of plants, the mysteries of the human body, life health care, psychological knowledge and history and culture. What I pay most attention to is the mysteries of the human body. It allows me to understand myself better and to cherish and protect my body. !In the mysteries of the human body, I understand that healthy people will not necessarily be healthier if they breathe oxygen, because breathing pure oxygen for a long time may cause oxygen poisoning and accelerate the aging of cells. Healthy people can do some appropriate things that consume them. Aerobic exercise, such as swimming and running, can strengthen the heart, lungs and brain function to improve the body's immunity and the liver's detoxification ability. I also understand why I need to carry a schoolbag on both shoulders, because carrying a schoolbag on one shoulder puts the weight on the body. If one side of the spine is compressed, the balance will be imbalanced. At the same time, the blood circulation of the compressed side will be affected, which will make you uncomfortable for a long time, causing one shoulder to be raised, a hunchback, spinal curvature and deformation, and even affecting the development of the heart and lungs. , so the schoolbag is carried on both shoulders close to the back, with the lower part leaning on the waist, the schoolbag is carried upright, and the chest is forward, which is conducive to healthy growth. We all should pay attention to the posture of carrying the schoolbag.
Books are really our good friends. We can acquire any kind of knowledge! Thoughts on reading "One Hundred Thousand Whys" 400 words 13
Today, I helped my mother fry As for the egg, I originally wanted to hold the whole egg with my hands, crush it and then pick out the eggshell. This would be easier to do!
But I tried my best to crush it, but I couldn't break it. I asked my mother, and she said, "I'm cooking, go read "One Hundred Thousand Whys" and find the answer yourself."
So, I opened the book, flipped through it, and finally found it. It reads: "Because it is oval-shaped, when you pinch it, it will evenly distribute the force you exert to the shell of the egg, so it will not break. This kind of 'thin shell' is also used in architecture." structure', which is labor-saving and convenient.
”
After reading this, I finally understood why there were no holes in the roof during snowstorms!
Then, I held the entire machine with my hands and squeezed it hard, but one of the I pressed my finger harder, and the egg really broke. The egg white and yolk fell all over the floor, and I was scolded by my mother!
The second time I hit the edge of the bowl hard, the egg also broke, so , I have concluded a truth, that is, if you spread the shell evenly, your power will be distributed to the shell, and if you apply force to one place in particular, the egg will break.
Students, listen. My explanation has given you a new understanding of eggs! In fact, there are many hidden sciences in life. Let us discover science, explore science, love science, and know the secrets of science together!! Read "One Hundred Thousands" "Why" 400 words 14

I didn't know about the Milky Way of Nine Heavens Planet before. After reading "One Hundred Thousand Whys", I realized. I know the formation process of celestial bodies. I know that Venus, Mercury, Saturn, Jupiter, Mars, Earth, Uranus, Neptune, and Pluto are the nine planets in the solar system, and the Milky Way is made up of many nebulae like the solar system. The earth we live in is just a "little star" in the universe.
Not long after, my mother, father and I took my brother and I to play in the animal park. At that time, we were very excited. There were a group of crocodiles, and the younger brother said to his mother: “Hey! Look, that crocodile is crying! "I saw it, oh, it really is. Then my brother asked me: "Sister, do you know why the crocodile sheds tears? "I said: "Of course! Because "tears" of crocodiles are a natural phenomenon, they are just excretory organs, and the excretion function of the crocodile's kidneys is not very perfect. The excess salt in the body must be excreted by a special salt gland. Scientists have also discovered that sea turtles, sea snakes, sea lizards and some seabirds also have salt glands similar to those of crocodiles. "My brother suddenly understood after hearing this.
This book allows us to learn more interesting knowledge. This book is an ocean of knowledge, boundless. "One Hundred Thousand Whys" is really a book that we can never tire of reading. Popular science book! My thoughts after reading "One Hundred Thousand Whys" 400 words 15
I remember that day, we stood on the stairs and smiled happily at each other. It turns out that every little moment with you is still there. I can still see the mirror, I can see your clothes, I can see the corners of your mouth raised… But I don’t dare to love you, because love needs to be well behaved and tied to you forever. I don’t have that confidence yet!
I love the book "One Hundred Thousand Whys". It is a comprehensive popular science book that contains astronomy, geography, nature, animals and plants. It has ten major sections: exploration of the human body, science and technology, transportation, etc. It has a wide range of knowledge and has everything you need. The mysteries of the universe are full of magic; the creatures on the earth are endless; the complexity of the human body's structure; the advancement of science and technology... .It is really meaningful. Just like when I saw the piranha plant on TV when I was a child, I thought it was a fictional thing at first. It was not until later that I learned that this kind of carnivorous plant does exist in the world. Plants rely on some small creatures to supplement their nutrients. There are about 400 kinds of them distributed around the world. As I write this, I can’t help but sigh: I was really ignorant in the past. The natural world is really amazing, and it has nurtured so many things. animals and plants.
Therefore, we should cherish our current life, love science, and reject superstition and heresy. Everyone has the responsibility to maintain the ecological balance of nature and protect the environment. Books have given me a more comprehensive and intuitive understanding of the natural world.
The infinitely wonderful and mysterious world unfolding around us leads us on the road to knowledge, to capture, discover, and explore every unknown world...
