One Hundred Thousand Whys

A hundred thousand whys 1 I really admire it! Is my good teacher-a hundred thousand why.

As soon as we opened our immature eyes, we began to explore the world. In the world, we always open our curious eyes and ask many questions: "How thick is the land? Why do trees grow leaves? ..... "But it is often difficult for us to express it in plain language, so you need" 100,000 whys ".

It's late autumn, and my parents and I are walking on the bank of Lishui River. The osmanthus trees around us are in full bloom, full of pale yellow flowers, trying their best to bloom their charm. At this time, I thought of a question, why can't flowers be black? With this question, I opened "100,000 Why" at home and found such an interesting content in the book-why do you rarely see black flowers?

The color of flowers mainly depends on carotenoids and blue-white pigments contained in many cells. Black is rare. Besides the pigment of flowers, it also has a lot to do with sunlight. Flowers are tender and susceptible to high temperature, so they generally absorb blue-violet light with low heat and reflect red-orange light; If a flower absorbs all the seven-color light waves, it will suffer more damage, so it is difficult to survive, which is why there are few black flowers.

After reading "100,000 Why", I benefited a lot. It gave me the opportunity to broaden my horizons and become a mentor and friend on my growth path.

100,000 Why 2 In the boundless ocean of knowledge, we still face the world with a childish face, full of curiosity and fantasy. I think there are 100 thousand reasons why knowledge is rich, because it contains many unsolved mysteries such as animal world, botanical garden, scientific knowledge and so on. It can lead us to the ocean of knowledge.

What attracts me most about this book is: Why not water the flowers at noon on a hot day? This question. It turns out that in hot summer, watering around noon is the most taboo, because at this time the soil temperature is high and the temperature difference with water is large. At this time, watering will suddenly reduce the soil temperature and immediately hinder the normal absorption of water. Therefore, water should be watered before 10 am or after 5 pm in hot weather. No wonder the last time I watered a pot of chlorophytum at noon 12, it withered soon. After reading this, I understand that it is not advisable to water flowers at noon in hot weather. From this, I think we all need a comfortable environment. If someone destroys nature and this living environment, we humans can't survive, so we should protect this environment.

After reading these 100 thousand why, I learned a lot of knowledge. I will make good use of them in my study. When you encounter problems, you will ask more why. In learning, think more and use your head more, and don't be carried away by difficult problems!

A hundred thousand whys, three whys, how many whys are there in life? 100,000. Why so many? In the green world; What you know in life; Among our animal friends; In the sky and on the earth; In the things around us; The mysterious nature and any part of our bodies hide thousands of whys and their answers.

For example: Why do tomatoes enter the menu? Why is frosted glass transparent when it meets water? Why is the little seahorse born by dad? Why does Heng know that there is an earthquake in the distance? Why did three gold coins become 6.5438+0.38 million francs? Why does the moon always face the earth? Why is air pollution harmful to human body?

These are the questions that "why" brings us. The answer is as follows: at first, people thought tomatoes were poisonous, but later a scientist tasted them and studied them. It is found that tomatoes are not only non-toxic, but also rich in vitamins A, C, K, P, Ca and Fe, which can enter the menu. The concave part of the rough surface is filled with water, and the light passes through it, so it refracts regularly; There are dense blood vessels in the pouch of male hippocampus, which provide nutrition for eggs and make them develop into small hippocampus; Zhang Heng built the seismograph more than 1800 years ago, and was the earliest scientist to predict earthquakes in the world. Because there is a calculation method called "compound interest" in the world, three gold coins become 1.38 million francs; The moon revolves around the earth while rotating; Soot in the air, automobile exhaust and 3.4 benzopyrene in asphalt pavement dust all have carcinogenic effects. A hundred thousand whys is "a hundred thousand whys"! Tell us so much truth!

100,000 Why 4 "Wow, that's cool! The wind is blowing, sister, come and see, the tree is badly shaken by the wind! " The younger brother said excitedly.

"Yes, but the grass under the tree doesn't seem to move?" So, I ran to ask my father. Father smiled and said, "Look it up yourself. I believe that knowing the answer in this way will make you remember more deeply! " I walked away in frustration. When I saw my mother coming back from shopping, I was happy to ask her the same question. My mother said, "Son, find the answer yourself!" " "So, I took out the book on astronomy and meteorology that my mother bought for me-"100,000 Why "for reference. Ha, finally found the answer: when the wind moves, it is easier to form a vortex movement because the ground is uneven or there are many obstacles below, so the wind is small; However, there are few obstacles in high places, so the friction is reduced and the wind is strong. Haha, that's the truth! Therefore, when the wind blows, the tall trees sway much harder than the grass on the ground! Through the search in the book, I understand that there is a saying called "a tree attracts the wind", which must be inspired by nature! Well, the process of finding the answer by yourself turned out to be so interesting and surprising.

At the same time, through this incident, we are also educated to be diligent in searching, and I believe you will get the same surprise as me!

A hundred thousand why five books are the source of wisdom, and books solve puzzles for me. There are many books neatly arranged on my bookshelf, among which my favorite is 100,000 Why.

When I was a child, I often asked my grandfather, "Grandpa, Grandpa, why are mimosa shy?" Grandpa always smiles and says to me, "There is a shy little girl hiding in the mimosa. The little girl hides when she sees someone coming. " I believe what grandpa said.

However, with the growth of age, my knowledge is also expanding, and I can't help but doubt grandpa's words. So, I carefully observed the mimosa again and found no little girl; If I don't touch it, mimosa won't close its leaves. However, I don't have any evidence, so I have to give up.

Some time ago, my mother bought me 100 thousand why, which reminds me of mimosa. I quickly opened the catalog to find out "Why are mimosa shy?" Don't say that. I found it.

It turns out that mimosa has a relatively enlarged tissue at the base of petiole, which is called "leaf pillow". The leaf pillow is full of water, which often swells and maintains a great pressure, and the lower part is greater than the upper part. When you touch the mimosa with your fingers, the leaves are shaken, and the water at the lower part of the pillow immediately flows away like the upper part and both sides. So the lower part of the occipital is concave, the upper part is convex, the leaflets are closed, and the petiole hangs down like a little girl.

I told this truth to my grandfather, who was very happy and said, "It's better to study!" " "

Books are the source of wisdom, and books solve mysteries for me. I love my hundred thousand why. It solved one problem after another for me. I love reading, and I love reading 100,000 whys more.

100000 why 6 classmates, do you know why the plane flies? Do you know why the telephone can make people far away talk to each other? Do you know why computers can meet people all over the world on computers through the Internet? If you want to know the answer, let's take a look!

The name of this book is "Thousands of Why", which contains science, geography, history and so on. The content is very rich and the knowledge is very interesting. Every page has color pictures. If you encounter words you don't understand, you can look at Pinyin, learn more words you don't know, and there are arrows to tell you the direction.

I have read this book completely, more than three times, but I still can't get enough of it, because its articles are not long, and I will give examples, write explanations, vivid images, and make people understand and learn. Not only that, there are many information and famous sayings about scientists.

Once, I casually turned to a page and turned to this content about telephone. I read it carefully with the question "why does the microphone make sound?" . When I finished reading, the problem was solved. I know that the telephone was actually invented by four scientists, but the telephone would not have been born in 1876 if Mr. Bell hadn't turned the screw by a quarter. A telephone can make sound by electric current. There is a thin carbon plate in the microphone. The sound will make the carbon plate in the microphone vibrate and promote the change of current. This is the principle of the telephone. Is it easy to understand?

Students, do you want to know about these extracurricular knowledge? Then read this book! This book has both scientific principles and natural mysteries. I think the wonderful content in this book will certainly attract you very much!

There are many books in my mind, but some of them have been forgotten. I still remember reading a profound book-100,000 Why. After reading it, I feel that it will be of great help in this book and in our real life. When I read this book, I learned the secrets of animals. It is mentioned in the book that what animals are poisonous and cannot be eaten; What animal is not poisonous and can be eaten? Apart from saying whether animals are poisonous, where are the body parts of animals? What about the various characteristics of animals?

Among them, what impressed me was where is mantis's nose? I have doubts in my heart: don't all animals have long noses? I decided to watch "100,000 Why". It turns out that mantis's nose is in the chest. Then I did an experiment, and the result was this. Later, I learned a lot from this book, such as plants, fish and airplanes. ...

Here, I learned the mysterious knowledge of nature. Let's stay with it all my life.

I really benefited a lot from reading this book. In our life, it helps us solve many problems and learn more knowledge. There is an old saying that is well said! The phrase "never too old to learn" will always be engraved in my heart, so that we can learn endlessly.

100,000 Why 8 My hobby is reading. I have many books, such as Diary of a Laughing Cat, Adventures of Pinocchio, Fairy Tales and so on. But what I like best is a hundred thousand whys, because it helps me learn more knowledge invisibly.

I remember one summer night, my father and I were walking in the country. I looked at the stars in the sky and suddenly asked, "Dad, do you know how many colors there are in the sky now?" Dad said without thinking, "Three kinds, yellow, blue and silvery white." I smiled and said, "No! The stars are not only yellow, but also red, purple, orange and green ... and many more! " Dad asked, "How do you know so much?" I smiled and said, "They are all reading books!"

"100,000 Why" not only increased my knowledge, but also improved my self-cultivation.

I used to throw things at animals when I went to the zoo, but after reading this book, I stopped throwing them because I knew animals were our best friends.

Because I often "show off" in front of adults, my parents call me "little know-it-all". In fact, all this knowledge is learned from "100,000 Why", so I like this book very much.

I want to read more books and be a useful person to society in the future.

I have read many books, including Journey to the West, Snow White, Arabian Nights, etc., but the favorite book I have ever read is 100,000 Why.

I was curious to open the book "100,000 Why" and see many profound questions on it. "100,000 Why" is a series of popular science books with countless contents. "100,000 Why" often introduces us to some interesting natural phenomena, such as how the "four seasons" of a year are formed. What color is the bottom of the sea? Why does the sea water turn blue? Why do fireflies glow? ..... from which I found many scientific truths and solved the mystery in my heart.

One of the articles that interested me was called Why Fireflies Glow. The luminescence of fireflies is related to the luminous body at its tail, which contains luciferase luminescent substances. When air enters the luminous body, fluorescein combines with oxygen in the air under the catalysis of luciferase, and the generated energy is converted into fluorescence. The more air enters the light emitter, the brighter the fluorescence. So fireflies don't shine at night, but the brightness is not as good as sunlight, so they think they don't shine during the day.

In the past, I knew nothing about the nine planets and the Milky Way. "100,000 Why" introduces us to the formation process of celestial bodies. I know nine planets, such as Venus, Saturn, Mars and Earth. Like the solar system, the Milky Way is composed of many nebulae. The earth where we humans live is just a "little star" in the universe.

"100,000 Why" is a good book. Every time I have a question that my classmates don't know, I can answer it, and I become my classmate's PHS. I like it very much. It lets me know that the world is so colorful and knowledge is so educational and interesting. It taught me that science is power and knowledge is wealth.

100000 Why do I always like to ask my mother all kinds of strange questions when I10? Why does it rain? How is the wind formed? The little hand is hurt. Why is the blood red? Even my teacher often calls me "little question mark" with a smile. During the summer vacation, my mother brought me a new "teacher", which is a set of "100,000 Why" books.

This set of books has helped me solve many mysteries in my life and brought me into a mysterious scientific world. For example, you can't play football or jump rope immediately after a meal, because a lot of blood is concentrated in the stomach to help digestion and absorption after a meal. If you exercise immediately, some blood will flow into the muscles, which will affect the digestion of food and cause indigestion. Also, blood is red because human blood contains red blood cells, which contain red iron-containing hemoglobin, which makes red blood cells red. When hemoglobin combines with oxygen, blood is dark red.

Children, isn't this set of books very interesting? Do you want to know why we dream, why dinosaurs are extinct, and why there are day and night? Come and watch a hundred thousand whys with me! Let's be a happy little fish in the ocean of knowledge and swim freely!

100,000 Why 1 1 In the third grade, because my parents were really busy at work, I had to get on the school bus and let it take me home. There are many people who take the school bus, some are freshmen, some are sophomores, some are at the same level as me, and there are big brothers and sisters in grades four, five and six, so the school bus comes home quite late.

After school every day, because I have to wait for someone, I am bored. I always go to chat with the uncle of the security guard at the school gate. Uncle security may have been bored for too long, so he chatted with me soon. Because I am young and don't know much, I always ask him "why":

"You are too young to do .../Why?"

"When you grow up, you can .../Why?"

And every time I ask a naive question, and there are so many questions that the security guard can't help but laugh and cry and have to answer them one by one. For a long time, he kindly called me "a hundred thousand whys" because I was too talkative! I also retorted with a smile, and then they chatted happily again, but the nickname was deeply imprinted in my heart and became an indelible memory. Because I stopped taking the school bus in the fourth grade, my relationship with uncle security has faded a lot, but when we meet, we will still make fun of a few words:

"Hey, a hundred thousand why, after school?"

"Well, goodbye, uncle!"

But now, I can't remember the face of uncle security for a long time, and he doesn't call me "a hundred thousand whys" anymore. However, I still remember the memories with uncle security.

100,000 Why 12 I like to ask questions since I was a child, and I always chase after my mother to ask them. Sometimes my mother is puzzled by me, so my mother took me to buy a set of "100,000 Why" and asked me to find the answer in the book myself.

The book "100,000 Why" is rich in content and has many categories, including astronomy, geography, biology, human body, health and medicine. , so that people can understand a wide range of knowledge. For example, why do people feel like falling off a cliff and twitching when they are asleep? It turns out that people sleep too easily and their brains think you are dead, so I remind you. Why do people eat three meals a day? Because in ancient times, people only ate two meals a day and were always hungry, so in order to make people not hungry, they changed to three meals a day. Why do dogs sigh? In fact, it's because dogs are expressing emotions just like people, but if a dog sighs continuously, it's sick. Why do people suffer from insomnia? Because you are under too much pressure, you will gradually become irritable, and naturally you can't sleep. why ...

Do you think the book "100,000 Why" can only teach you knowledge? Then you are all wet. It can also communicate with you like a human. When you are sad and cry, it will tell you that tears are a good thing and detoxify you.

When you are very excited, it will tell you not to get too excited, which will make people's heart beat very fast, and stopping immediately will lead to cardiac arrest; When you are ecstatic, a tear suddenly falls from the right, which will tell you that it is sad to shed tears first in your left eye and happy to shed tears first in your right eye. ...

After listening to my story, I am moved, so go buy a set and read it carefully, and share the happiness of reading with me!

100000 Why 13 I had nothing to do today and wanted to read my previous books again, so I took a few from the shelf.

I wrote down comic books, fairy tales, composition books, idiom stories and Olympic inferences. Suddenly found four books, 100 thousand why, a set of four books. I wiped the dust off their bodies with paper and chose the science edition. I looked at it and found a short article about triboelectrification. I know that wind, water and solar energy can generate electricity. I looked at it curiously and found it interesting, so I did the experiment according to the book.

I took a square piece of white paper, tore it into pieces, took a water-based pen with a pen cover, and prepared for work. All right, let's go! I put on my pen cover, stuffed it into my hair, and rubbed it hard, faster and faster. I touched it with my hand, so hot! I quickly put the pen into the pile of paper. In an instant, the pen held the paper tightly like a magnet, and then the paper fell off with a wave of his hand. I was ecstatic and did it again, but the pen still clung to the paper and did not move.

The experiment is really interesting, but we should not only do it, but also understand the truth, so I opened the book again, and the book said that there are positive and negative charges in objects, and they attract each other. When the pen rubs in the hair, it will attract small pieces of paper, indicating that the pen has charge movement, which is the reason for friction electrification.

So that's it. After reading it, I was quite touched. In fact, science is in life. As long as you are willing to seriously discover and dare to practice, science is around us. There are many scientific truths in life. For example, when a candle is covered, the flame will go out, because the candle needs oxygen to burn. Without oxygen, the fire will go out.

I am determined to find more scientific principles in my life.

A hundred thousand whys 14 I read a book today called a hundred thousand whys. After reading this book, I can't calm down for a long time. This book has solved many problems for me.

This book shows me the vast universe. Let me understand why the earth environment is not the only living environment; Why are space clouds nebulae? Why is the Milky Way a spiral galaxy? Why is there an extragalactic galaxy theory ... all these have solved my doubts.

Also let me know a lot of physical and chemical knowledge, such as why the aurora appears in the sky near the North and South Poles, why the earth is constantly changing, and why the area of the earth is 5 10/00000 square kilometers. What is particularly surprising is why the land area is 5 10/00000 square kilometers.

Let's talk about animals. Animals are friends of human beings. But animals also have many magical places, such as frogs blinking when eating, crocodiles crying, flounder eyes on the same side, swan collective expedition ... what a world!

Finally, let me introduce plants to you! There is nothing in the book, such as why some plants can swim? Why do some flowers and plants grow indoors? Why some flowers bloom at night … makes me curious.

The book "100,000 Why" has collected a lot of knowledge and let us know a lot of knowledge that we don't know.
