After reading this set of "100,000 Why", it reminds me of a sentence that Gorky said: books are the ladder of human progress. This sentence is so right! At the same time, I also deeply appreciate the greatness of scientists. They have developed rich scientific and technological achievements with their own wisdom and strength, which is really admirable! Finally, I understand a big truth: knowledge can never be learned, and if you want to learn more, you have to pay more.

It was Saturday afternoon, and I went to the bookstore and bought a set of books: 100,000 Why. After returning home, I opened the wrapping paper, opened the book carefully with curiosity and began to read carefully.

This set of books contains knowledge of animal kingdom, botanical garden, encyclopedia of life, geography and meteorology, human mysteries and so on. The knowledge in the book is not all dense words, words and cartoons as I imagined.

Beautiful! Why is the elephant's nose so long? Why do people age so fast in space? Can plants catch a cold and have a fever? These questions can't be answered in Chinese books, but I found them in the book "100,000 Why". In this set of books, illustrated, vivid and interesting, can not only help us broaden our horizons and learn more knowledge, but also improve our quality and success. This is really my silent little teacher!

I must be a careful and thoughtful student in the future, observe things around me carefully and master more knowledge.

Reflections on Reading Fan Wensan's A Hundred Thousand Why's

I read this book with curiosity. This is a book related to science. It is also related to mathematics in our life, but I am curious and want to finish reading this book. Unfortunately, the time was too short, and I only saw part of it. In this book, what I am interested in is "Why all beehives are hexagonal". After reading the topic, I thought the hive was round. Why are they all hexagonal? I took the question and read it carefully. Reading and thinking remind me of the real hive in reality. It looks neat from the front or side, but the hexagonal honeycomb does have certain scientific nature. There is a French scientist, "Urah", who measured it at the beginning of18th century. He told us a rule, that is, beehives. The obtuse angle of each diamond is 109 28' (pronounced as 109 28), but what is the secret? Because of the calculation, the result is exactly the same as the angle of the honeycomb, which is stable, but it is too different from the circle we guessed.

From this reading, I feel that although it is a normal thing. It is not unreasonable. Everything has its scientificity and regularity. However, human beings have gained a lot of enlightenment from the structure of honeycomb, for example, applying it to the materials for manufacturing aircraft can save materials, reduce the weight of aircraft, and ensure the firmness, heat insulation and sound insulation of aircraft. Similarly, the principle of beehive is also extensive in architecture! The magical hive embodies the infinite wisdom of nature, which makes me think a lot and makes me feel great. We should pay more attention to the laws of all things, and we will explore more abundant knowledge and truth.

Only time is the only criterion for testing truth.

Reflections on reading the model essay 4 of 100,000 Why

I read a book called "100,000 Why" these days. It mainly focuses on scientific content. I like reading "100,000 Why" very much, and I like this article about nuclear weapons best. Let me tell you something!

Nuclear weapons are so powerful that they can blow up a city in a short time, so they are very dangerous. For example, Japan was defeated in World War II and threw nuclear weapons (atomic bombs) at the United States, and even the grass died in that land. The use of nuclear weapons is prohibited in today's world. There are satellites in space that detect the existence of nuclear weapons. Once found, you can get information in time and take corresponding protective measures.

Every time I read this story about nuclear weapons, I get scared. Nuclear weapons are so dangerous that we should prevent any country in the world from using them. Now I heard that some countries are fighting for the North Pole and South Pole, because nuclear weapons are stored under the ice there, so satellites can't detect them. What is the real purpose of these countries? How many people will die if a nuclear weapon is accidentally detonated or leaked? (For example, last year's Fukushima nuclear leak in Japan affected many places. )

Once a nuclear weapon explodes or leaks, the world environment will also change. How terrible! We in China don't want to do such a thing. I'm very proud. I'm from China! I think the production of nuclear weapons should be banned, so as to better protect the earth!

After listening to my introduction, you think nuclear weapons are dangerous!

Reflections on reading the model essay 6 of 100,000 Why

During the winter vacation, my mother bought me a book "100,000 Why", which is really a very good book! There is a lot of knowledge in it, and I seem to have entered an ocean of knowledge.

This "100,000 Questions" is the work of Mikhail Ilya, a former Soviet writer. This book is divided into six parts, or six "stations", and there is an appendix. It contains knowledge about water, fire, food, metal, mirrors, animals, plants and so on.

It never occurred to me that in a house, the author found so many observable things and could ask so many questions. He must have observed the object from all angles and made a good record. I still have a long way to go in this respect. I really admire miriya!

The book "100,000 Why" is very different from the popular science book I read before. This book is like a snowball of knowledge. The deeper you read, the bigger the snowball of knowledge. At the end of reading, everything came together, which made me understand that everything is closely related, such as sports.

Things and plants, water and fire. Unlike other popular science books, they are all described one by one according to specific things. Therefore, I prefer the book "100,000 Why".

By reading this book, I understand that science is all around us. I will observe carefully and think more in the future. This is my greatest gain from reading this book.

Reflections on reading the model essay 7 of "100,000 Why"

Reading is my favorite thing to do after school every day. My mother bought me many books. My favorite reading is 100,000 Why, from which I learned a lot.

Students, do you know why crocodiles cry when swallowing food? Is it because of sadness? Or pretend to be merciful? Actually, it's not. It turns out that the crocodile's kidney has degenerated. It drinks a lot of sea water every day, which contains a lot of salt. Crocodiles have a pouch that secretes tears in their eyes. This is a special salt processing factory. This pouch can collect excess salt and excrete it through tears, so crocodile's tears are a normal physiological reaction, not that it pretends to be merciful, so people say crocodile's tears are fake.

And why do turtles live long? What does bee dance mean? Why can reading glasses see clearly? How does a mobile phone transmit sound? How does the satellite know our location? ..... too much knowledge for me to explore in the sea of books.

Books are my good friends. They took me into nature, into history, into science and learned about this colorful world.

Fortunately, there is "100,000 Why" in the hot summer, which makes me feel comfortable and fun.

Its fat body contains endless knowledge, which has solved the mystery that I have never been able to solve, and made me gain a lot of knowledge and benefit a lot.

I know why mimosa is shy in the book. It turns out that the petiole base of mimosa has an enlarged tissue called "leaf pillow", which contains a lot of water. When we touch the leaves, the leaves vibrate, the water in the pillow flows forward, the back of the pillow droops, and the petiole droops, which makes the leaves close like a shy little girl. After a period of time, the water flows back to the lower part of the leaf pillow and the leaves open again. Before I remembered reading this book, I naively thought that there was a special organ hidden in this grass, and even wanted to pull it up and dissect it! At that time, I was so stupid and cute!

Why are vegetables sweet in winter? Why do chickens eat pebbles? Why do crabs spit bubbles? Cattle eat grass, why hesitate ... all kinds of interesting questions, like a big magnet, attract me. I hold it in my hand when the morning light is dim; When the moon is high, I still hold it in my hand. ...

This book is a mentor and friend who accompanied me through my childhood. It is an amazing book, which will make people very smart. Students, you also go to study!

Reflections on reading the model essay 9 of "100,000 Why"

I read a book "100,000 Why" during the summer vacation, which was very good. Mainly talking about some things about environmental science, I can't put them down for a day.

After reading "100,000 Why", I learned a lot of things that I didn't know at ordinary times, such as: Why is there a sandstorm? It is caused by excessive reclamation, overgrazing and deforestation, which has caused serious damage to plants on the earth; Why not exercise in foggy days? Because when fog forms, it is often accompanied by an inversion layer, so the atmosphere is very stable, convection is weakened, and pollutants such as water vapor and dust in the air are not easy to spread into the air, so they can only stay in the air, causing serious pollution ... There are many detailed answers in the book, which makes me suddenly realize.

A hundred thousand reasons can also help many people who don't know. Once at noon, grandma was cooking in the kitchen. I went into the kitchen to wash my hands, only to find that the kitchen was full of smoke, which made me feel dazzling and suffocating, as if it was difficult to breathe. I asked my grandmother strangely, "Grandma, what's the matter?" "I don't know!" Grandma coughed a few times because of choking. Suddenly my eyes lit up, and I thought that seeing kitchen fumes in "100,000 Why" would affect people's health. So, I suddenly realized to my grandmother, "This is because you heated the oil to smoke. Doing so will not only destroy the nutrients of the dishes, but also seriously pollute the air in the kitchen. " Grandma nodded and said, "Be careful next time. It won't happen again."

"100,000 Why" tells me a lot of knowledge, and I am determined to protect nature and protect our environment.

Reflections on reading the model essay 10 of "100,000 Why"

My mother brought back a book the other day, saying it was very good and recommended me to read it.

After reading some of them, I have a good understanding of one of them, which is called "Why can't I laugh when I tickle myself".

When I was in the fourth grade, my classmates often teased me. Every time I itch badly, I kneel on the ground and laugh, and my classmates will laugh at me. I thought to myself, aren't you ticklish, too? You're laughing at me. I will try to be an itch-free person. So, I made up my mind to be an itch-free person. When I got home, I kept tickling myself, but I didn't laugh. I don't believe it. I tried again, but I still didn't laugh. The next day, I proudly said to that classmate, "I'm not afraid of itching anymore." If you tickle me, I won't laugh. " That man doesn't believe me. Get ready to sneak up on me when I'm not looking. But at this time I was ready to take precautions, and he didn't succeed. I let my guard down. It's too late, but too soon. He punched me when I wasn't looking, and I laughed again. I am very confused in my heart. Later, I read in the book: I, um, itch myself, and my brain has prepared for prevention in advance, so I won't laugh, while others itch when you are not paying attention and my brain is not prepared, and you will laugh.

I suddenly realized, thinking, it seems that I have to suffer a lot to become a person who is not afraid of itching. Besides, many strange ideas popped up in my mind: why can't the brain predict other people's actions …

This book is really worth a hundred thousand whys. It contains a lot of knowledge and can arouse our whimsy.
