Reading Interesting Encyclopedia 1 This summer vacation, I read an unforgettable book, a book about plant knowledge, called Interesting Encyclopedia. This book has given me a lot of scientific knowledge!
Why is cactus covered with thorns? Cactus looks very special, but it is covered with thorns, so people can only appreciate it, but not near it. The thorn on the cactus is a kind of "metamorphosis". The metamorphosis of this plant organ is not a deformity or a morbid condition, but a way to change its own structure in order to adapt to the environment and facilitate survival. Cactus is a kind of "fleshy and prickly" plant, which grows in arid areas. Usually, this kind of plants adapt to the arid environment, that is, let themselves expand the water absorption area as much as possible and increase the absorption; At the same time, the evapotranspiration area is reduced and the water loss is reduced. Therefore, the stem of cactus becomes fleshy and pulpy, which is beneficial to store a lot of water; The main part of plant water evaporation is leaves. In order to reduce water loss, its leaves gradually degenerate, and some even become needles or thorns. Therefore, the cactus is covered with frightening thorns!
So what makes mint cool? You may not have seen mint trees or leaves, but you must have eaten food made from them. These foods must have a unique feature, that is, cool and refreshing, with a unique aroma. Mint is cool because there is a volatile "peppermint oil" in its stems and leaves, and its main component is menthol, which is an aromatic cooling agent. Mint is not only cool and refreshing, but also can be made into various summer foods. More importantly, it can also be used as raw materials for medicine, cosmetics and other industries. In addition, there are many mint ingredients in daily necessities, such as toothpaste and soap, which are used every day and have a wide range of uses.
This book has made me understand a lot. The world is full of miracles, and there is science around us. We should have bright eyes to find them!
Reading Interesting Encyclopedia 2 During the summer vacation, I read the book Interesting Meteorological Encyclopedia and was immediately attracted by the colorful and wonderful meteorological conditions in the book.
Here, I feel the pulse and breath of the earth's atmosphere, the mystery of the changing situation, and the strange scenery of rainy city and foggy city. Among them, what I appreciate most is the silver fog on the Shili long embankment in Jilin.
Wu Song, commonly known as tree hanging, as its name implies: something hanging on a tree. What on earth is hanging on the tree? I carefully observed the illustrations in the book: like snow, not fluffy; Like frost, not as thin as frost. If the frost layer is thicker and tighter, it will be more like it. If so, I am ecstatic: there are trees hanging in my hometown to build lakes. In the winter of March 9, houses, roadsides and hillsides, especially the big trees by the river, were covered with thick frost. Looking from a distance, it is white, clean and beautiful; Close-up, silver thread, silver strip, layer by layer, covered with the crown, like the hair petals on the head of a winter girl, emitting charming brilliance! Really beautiful!
Watching, my joy went down again. It seems that the conditions for fog formation are quite high: first, saturated water vapor, and second, the temperature should be reduced to about MINUS 30 degrees Celsius. The lowest temperature of Jianhu Lake in winter is around minus 10 degrees Celsius. Looking at the temperature alone, the "Wusong" in our lake is unqualified and belongs to "fake and shoddy products". Old people call it the first frost, which is worthy of the name.
The first frost is the first frost. Although it is not as graceful as Wu Song in Jilin, it also has a unique charm of small jasper.
I love you, belonging to the beauty of our hometown-Chu Shuang.
After reading the interesting encyclopedia, I feel that I have returned to my grandmother's house in the country during the National Day.
No.65438 +0, the sky is surprisingly blue, and a few faint clouds are randomly suspended under the canopy. Grandma picked up a hoe and said she would go to the vegetable garden. As soon as I heard it, this is a good opportunity to get close to nature! I was busy putting down my homework and went to "nature" with my grandmother.
When playing with mud, I accidentally found a greasy earthworm, which felt great. Just wanted to dismember the earthworm with a hoe, grandma said, "It took several years to learn that frogs and dragonflies are good friends, isn't earthworm?" Earthworms can help me loosen the soil! "I'm surprised. When I got home, I quickly opened the Encyclopedia of Interesting Animals, searched carefully from page to page, and finally found the answer. Grandma is absolutely right. Earthworms have many benefits to human beings. Earthworms move in the soil, making the soil loose, making air and water penetrate deeper into the soil, which is beneficial to plant growth and can improve the soil. Earthworms, commonly known as Quji, or Pheretima in Chinese medicine, are cold and alkaline, and can clear away heat, calm the liver, relieve asthma and dredge collaterals. Indications: high fever, mania, convulsion, wind-heat headache, red eyes, hemiplegia, etc. Earthworm ash mixed with rose oil can cure alopecia; Earthworms contain lumbrokinase, and earthworm enzyme also has the functions of reducing blood viscosity, inhibiting platelet aggregation, anticoagulating blood and promoting blood flow. Can be used for treating apoplexy sequelae, arteriosclerosis, hypertension and hyperviscosity. The efficiency of using earthworm to treat organic waste is very high. For example, 654.38 billion earthworms can swallow 40 tons of organic waste a day. Earthworms can improve soil fertility. Rotten organic matter and a large number of soil particles eaten by earthworms are digested to form feces, which are rich in nutrients such as nitrogen, phosphorus and potassium. Earthworms contain a lot of protein and fat, and have high nutritional value. They are excellent feed and food.
After reading Encyclopedia of Interesting Animals, I lamented that earthworms are well-deserved friends of mankind. We should protect animals. "Fun Hands-on Encyclopedia" really benefited me a lot!
After reading the interesting encyclopedia, I feel that there are four books, which are an ocean of Wang Yang, and let me swim in the ocean of knowledge. There are many kinds of books, such as children's books, popular science books, adventure books, reasoning books ... but my favorite book is an interesting encyclopedia of animals.
Encyclopedia of interesting animals is an encyclopedia about animals, which tells many stories about animals and some common sense, all of which are very interesting. I learned a lot from this book. For example, I always thought that the blood of animals is red, but among arthropods, there is an animal called horseshoe crab, and its blood is blue. This blue blood will coagulate when it meets bacteria, so it is widely used as a reagent to detect whether there are bacteria in the medical and food industries. In the vast ocean, there are many lower creatures whose blood is colorful. In addition, many people think that mice are bad, so do I, but two short stories in the book changed my mind: it was one day in 1994, and one day after the rainstorm. A big mouse rushed out from the foot of the wall, grabbed the old man's trouser legs and dragged him out of the house desperately. The old man walked out of the house with it. At the moment when the old man left home, a flood rushed down and rushed through the old man's home. The old man escaped the robbery. Now I think that the mouse is a spiritual animal and can give up his life in the face of natural disasters. The story of the pet savior in this book is even more touching, which makes me memorable.
Oh, this book has given me a lot of knowledge, happiness and happiness.
There are five books after reading the interesting encyclopedia. Is the sea of Wang Yang, let me swim in the ocean of knowledge. There are many kinds of books, such as children's books, popular science books, adventure books, reasoning books ... but I like that interesting encyclopedia of animals best.

After reading Fun Encyclopedia, I learned the text of making a beautiful leaf, knowing that plants can carry out photosynthesis and release oxygen that human beings need. I think plants are really amazing, so I borrowed the book Encyclopedia of Interesting Plants from the library, so that I can learn more about plants.
This interesting book took me into the strange world of plants and felt the wonder of plants. Know something I didn't know before. For example, the nutrition that chlorophyll can obtain through photosynthesis is a major feature of plants, while fungi, saprophytes and parasitic plants are exceptions. In addition, plants are tough, have no moving organs, and are usually fixed in one place, which is also a feature of plants. Of course, some plants are not like this, such as rolling grass. It is this exception that makes me fall in love with these complex plants.
Plants absorb my exhaust gas day after day, constantly making oxygen indispensable to human beings and purifying the air all the time. Plants use their roots to protect water and soil from all kinds of natural disasters. Plants provide food, vegetables, fruits and other necessities for human life. Plants give people spiritual enjoyment with their bright colors. Plants have given too much to human beings. But what about humans? For the sake of temporary self-interest, a large number of trees are cut down and wild plants are constantly destroyed, which makes the living space of plants worse and worse, and many natural disasters are approaching. For the sake of our earth, for the sake of the plants we live on, and for the sake of our living environment, please protect the grass and trees around us and make every corner of the earth full of green.
I believe that as long as we treat plants well, the earth will one day be full of flowers and laughter.
After reading the interesting encyclopedia, I feel that plants and animals constitute the most dynamic scene in the macro world.
Plants, although not dynamic and static like animals, are alive. We can't ignore them because they are so small and unattractive. Interesting encyclopedia of plants This book not only describes the characteristics of 65 plants, but also writes some short stories about plants.
The world is big and wonders, and so is the plant world. Some plants will turn their leaves, flowers or fruits into their own weapons to defend themselves, such as biting grass, which will turn their leaves into weapons. As long as someone touches these little guys, they will bite that person hard; In order to survive, some plants have to turn their branches and leaves into predatory tools, such as venus flytrap. They grow in barren places. In order to supplement nutrition, they turn their branches and leaves into "clips" that secrete a sweet substance, thus attracting some insects to "eat" here. When they are not paying attention, they suddenly get caught in the "clips" and let themselves have a good meal. There are also some plants that provide information for human beings, such as meteorological trees. As long as the weather changes slightly, the color of leaves will change. ...
"Heaven supports people with everything." Plants make oxygen for human beings, protect water and soil with roots, regulate climate, and prevent natural disasters such as soil erosion, land desertification and mudslides; They provide food for human beings and make them full; Also use their own bright flowers for people to watch, giving people spiritual satisfaction. ...
However, how do humans repay them? In order to make money, build houses and have selfish desires, greedy human beings began to cut down a lot of forests, turn the land into wasteland, reduce grasslands, forests and lakes in a large area, and worsen the living space of the post. Many plants were on the verge of extinction, and rampant floods and sandstorms followed. ...
Is this the result that plants want? The answer is no.
Therefore, in order to dedicate a lot of plants, for the home where we live and for our dear Mother Earth, please take care of everything around us and don't let our next generation see them only in museums!
