Germinating knowledge

Eat fish head for health in spring, because fish is rich in nutrition. Fish head is the golden part of fish's whole body, fish eyes and fish brain are rich in nutrition, and fish must rely on gills and gills of the head to breathe, so the essence of fish is in the head, and the season of the year is in spring.

Just kidding!

Spring feeding principle:

According to the custom of China people, beginning of spring marks the beginning of spring. It is the first of 24 solar terms in a year, which is around February 4th in the solar calendar every year. At this time, the temperature gradually rises, and the freezing begins to melt. Everything in the world, including the human body, after being dormant in winter and March, the yang begins to rise, and everything begins to sprout, which makes people feel a brand-new atmosphere. "Spring should be the way to keep in good health" should encourage this kind of "budding" information. At this time, the "liver qi" in the human body also rises. Because of stagnation of liver qi, it is not suitable for depression, so vent. Wake up after the rain, then you can hear the spring thunder, and the hibernating animals begin to wake up and be dug up, which is the result of the breath of "life". At the vernal equinox, day and night are equal in length. The ancients called this "half yin and half yang". By Qingming Festival, rainfall increased, humidity increased, grass sprouted and large-scale spring ploughing began. At this time, the liver qi in the human body is vigorous, and those who are not properly maintained in winter are prone to fever in spring. General chronic diseases such as hypertension, asthma, skin diseases and allergic diseases are easy to recur at this time. Also, patients with gastric and duodenal ulcers will suffer from gastric bleeding due to improper diet. Therefore, shrimp, bamboo shoots, roosters, seafood and other foods should be avoided in the diet. According to the above principle, in the whole spring, the principle of food supplement is to reduce acid and sweet, and nourish temper. Because liver qi is strong in spring, it is easy for liver qi to attack spleen soil, causing spleen and stomach diseases, and sour taste is the original taste of liver. Therefore, at this time, the sour taste should be reduced, and the liver qi can no longer be encouraged to avoid being too strong, so that the temper can be protected from attack. Sweetness is the original flavor of spleen. In order to resist the possible invasion of liver qi, increasing sweetness and strengthening temper can strengthen the body's defense. For example, tangerine peel for soothing the liver and regulating qi, Hangzhou chrysanthemum for calming the liver and calming the wind, and grain buds for soothing the liver and strengthening the spleen are all timely foods. In spring, nature provides many wild vegetables for human beings, such as Malantou, alfalfa and chrysanthemum, which have a good effect of clearing liver and improving eyesight. It is precisely because the spleen and stomach are easily damaged at this time that we should pay attention to eating less indigestible food, especially the elderly. If alcohol should not be excessive, cold food, zongzi and sticky, cold and greasy things should be strictly controlled so as not to affect the normal function of viscera. If you don't nurse properly, it will hurt your liver qi. Damage of liver qi in summer will lead to the loss of seasonal heart fire. In summer, the heart fire will be insufficient, and cold water will attack, which will easily lead to cold change, that is, heat will not be hot, and the elderly will not grow up. Traditional Chinese medicine calls this phenomenon "anti-spring spirit and less care for the elderly".

Spring health should be avoided:

Food is the most important thing for people. If you eat properly, it's like having a health care doctor to help you improve your physical fitness and resist various diseases from the outside world. Similarly, diet should be taboo and has always been valued by people. So what are the dietary taboos in spring? Sun Simiao, a doctor in the Tang Dynasty, said: "On the seventy-second day of spring, acid is preserved and sweetened to nourish the temper." It is also recorded in Gao Lian's "Eight Notes on Respect for Life" in the Ming Dynasty: "In spring, the taste of food should be reduced and the sweetness should be increased to nourish the temper." It means: when the liver is strong in spring, eat less acidic food, otherwise it will make the liver fire stronger and hurt the spleen and stomach. You can eat more sweets at this time. Therefore, you can eat more in spring:

1, yam: "warm but not sudden, slightly fragrant but not dry", which has the functions of strengthening the spleen and stomach and tonifying deficiency.

2. Bamboo shoots: Besides protein, they are also rich in minerals, such as calcium, phosphorus, iron and vitamins. Fresh food is especially good.

3, pea seedlings: seasonal vegetables, for patients with hypertension and diabetes, juicing is the most suitable.

4, leek: warming the middle and benefiting qi, warming the kidney and warming the yang. It has a good effect on soreness of waist and knees, impotence and nocturnal emission. Leek is warm and beneficial to people, with early spring leek and leek coming out of the market as the best.

5, Toona sinensis leaves: have the effect of expelling wind and detoxifying, invigorating stomach and regulating qi. Seasonal dishes in spring are delicious when eaten with tender leaves, and are often eaten as cold tofu and scrambled eggs. However, the leaves of Toona sinensis are "hairy" and people with chronic diseases should not eat them. Others such as lentils, spinach, cauliflower, coriander, jujube, honey, beans, dairy products, eggs, lean meat and fruits are all suitable for spring consumption.

6. Lycium barbarum: In early spring, Lycium barbarum grows tender seedlings, also known as Lycium barbarum or Lycium barbarum seedlings. They are slightly bitter, but refreshing and can clear fire and improve eyesight. People often use them to treat internal heat due to yin deficiency, dry throat and sore throat, rising liver fire, dizziness and low fever. Lycium barbarum contains inosine, glutamic acid, aspartic acid, arginine and so on. , and rich in nutrition.

According to the theory of traditional Chinese medicine, there are also some things that should be avoided in spring. For example, don't eat mutton, dog meat, quail, buckwheat, fried peanuts, fried melon seeds, sea fish, shrimp and spicy things in March.

This budding simple story tells what two fathers did?

The article "The Story of Giving" mainly tells: Once upon a time, there was a man who got lost in the desert. He was dying of hunger.

But he still walked with heavy steps step by step. I don't know how many steps and how long it took, but he finally found an abandoned hut.

The house is very shabby, and obviously no one has lived in it for a long time. He walked around the house and found a water pump. He pumped hard, but no water came out. He was very disappointed. Suddenly he saw a kettle, the mouth of which was full of water, and there was a note on it.

The note says that water will come out as long as it is poured into the water absorber. He thought about who would go in, but he was afraid of coming out of the water.

After much consideration, he finally poured the water in. As a result, he drank a bucket full of water. This simple story tells us that as long as we put our own interests aside, we will gain a lot.

It's like getting a spring in the desert. I always put myself first in my work, and I don't care about other people's affairs.

Over time, I gradually became selfish and indifferent ... I remember once, I played with other children. As for me, I want to build a big house, so I need many building blocks. Halfway through, the blocks disappeared, so I "borrowed" some blocks from other children. But they refused to lend it to me, saying it was not enough.

When I got angry, I tore down the building block "house" that one of their children had just built. Build my big house.

The unlucky child is very sad. But I still had a good time there.

At this point, I know it's too bad for me to do something. I shouldn't put my own interests first. Hey, I made a mistake.

3. How to read "Germination"

1。

From the sentence of @ 1, I understand that children are lively and naive by nature, and they are always full of hope. Although he clearly knows that he can't grow grapes in this way, he has been expecting this grape seed to germinate.

His thoughts are not limited to old ideas, he wants to have his own creation, and he wants to sow his dreams through his own hands! This is a spirit worth learning. .

From the sentence of @2, I understand that the boy's father is a selfish father, with a grumpy personality, regardless of the child's physical and mental feelings. He only knows that letting children do some worthless things has been corroded by ordinary life, which is very harmful to children and is not conducive to their healthy physical and mental growth! 2。 @ 1 If I were a boy, I would say: Yes, I forgot to water them every day.

I believe that one day these grapes you planted will sprout and blossom! Because the girl's father, in order to let the girl complete the miracle in her heart, secretly planted grape branches without telling the girl. He gave the girl the dream of working miracles.

Instead of ruining your dreams like your father! 3。 A boy's father: a selfish father who is corroded by a dull life, regardless of the child's physical and mental feelings.

Girl's father: He knows the child's inner feelings and is a kind and kind father.

4. Universal common sense

In natural science, astronomy is a basic subject to study the movement, structure, origin and evolution of various celestial bodies in the cosmic environment outside the earth. Its history can be traced back to the embryonic period of human civilization. In ancient times, nomadic people needed to identify the direction when they migrated by aquatic plants, and agricultural people needed to determine the season when they planted seeds on time. In the long-term practice year after year, they gradually discovered the close relationship between these major events affecting their lives and astronomical phenomena such as the sun, the moon and the stars. Babylonian clay tablets, Egyptian pyramids and Oracle Bone Inscriptions in China Yin Ruins all left rich examples of the birth of astronomy. Astronomy has always made great contributions to the progress of human civilization. /kloc-Heliocentrism of Copernicus liberated natural science from the shackles of medieval theology for the first time in the 6th century. The classical mechanical system established by Galileo and Newton in the17th century to study the laws of motion of celestial bodies in the solar system is still the basis of modern engineering science (including aerospace science). The research on the internal structure and energy of the sun and stars in the 1930s produced the concept of thermonuclear fusion, which provided enlightenment for human beings to use nuclear energy. Especially in the past half century, human's enthusiasm for exploring the universe, on the one hand, has strongly promoted the development of a series of high and new technologies such as telemetry and telecontrol, space technology and computing technology, and directly served the national economic departments such as global communication, resource investigation and weather forecast. The application of these technologies in astronomy has made people's understanding of the universe advance by leaps and bounds. For the first time, it can be explained from the unified principle, from elementary particles to chemical elements, from galaxies to stars, from the sun to the earth, from protozoa to humans, it is tens of billions.

The earth where we live is an ordinary member of the solar system. The central celestial body of the solar system is the sun, which is a gas ball with a radius of about 700,000 kilometers and a surface temperature of 6000K K. Its core temperature is as high as1.5,000 K, and a nuclear reaction of hydrogen fusion into helium occurs. The light and heat on which we live are produced by this nuclear reaction. There are nine planets in the solar system, namely Mercury, Venus, Earth, Mars, Jupiter, Uranus, Neptune and Pluto. The outermost Pluto is about 6 billion kilometers away from the sun. There are thousands of asteroids running between Mars and Jupiter. There are comets and meteors in the solar system.

There is a band of light across the sky in the clear night sky, which is called the Milky Way. In fact, it is a huge celestial system composed of stars and diffuse matter, called the Milky Way. The luminous part of the Milky Way is about 70,000 light years in diameter and 20,000 light years in maximum thickness, like a rotating discus with a flat protrusion in the center. The sun is an ordinary star in the Milky Way. There are about 200 billion stars in the Milky Way, which are far apart from each other. Proxima centauri, which is closest to the sun, is also 4.3 light years away, which is 60 million times the radius of the sun. In addition to stars, there are many gas and dust masses in the Milky Way, called nebulae. Some nebulae contain a large number of molecules, called molecular clouds, which are often the places where stars form.

Outside the Milky Way, there are1000 billion huge celestial systems, which belong to the same structural level as the Milky Way and are collectively called galaxies. Andromeda galaxy, the farthest celestial body visible to the naked eye, is one of them. It is 2.25 million light-years away from the Milky Way, but it is the nearest galaxy of the same size. The distribution of galaxies in the universe is uneven, some in pairs, some in groups, and large clusters of galaxies even contain hundreds of galaxies. Some galaxy clusters have gathered into larger supercluster, and no uneven signs have been found between more than 500 million light-years and 654.38+0.5 billion light-years observed so far.

5. Primary school students have little knowledge of science and technology

1. Why do the stars twinkle?

We see the stars shining, not because the luminosity of the stars has changed, but because of the occlusion of the atmosphere.

The atmosphere is between us and the stars. When starlight passes through the atmosphere, it will be affected by the density and thickness of the atmosphere. The atmosphere is not absolutely transparent, and its transparency will change according to its density. So when we look at the stars through it on the ground, we will see that the stars seem to be flashing.

2. Why do people yawn?

When we feel tired, a lot of carbon dioxide has been produced in our bodies. When there is too much carbon dioxide, oxygen must be supplemented to balance the needs of the body. Because these residual carbon dioxide will affect our body's functional activities, then the body will send out a protective reaction, so we yawn.

Yawning is a deep breathing action, which will let us breathe in more oxygen and expel more carbon dioxide than usual, and it can also eliminate fatigue.

6. Little is known about life meteorology

Meteorology is a subject that takes the atmosphere as the research object, explains the characteristics of large-scale agricultural meteorological gases from both qualitative and quantitative aspects, and focuses on the weather situation and changing law of the atmosphere and weather forecast.

Meteorology is a branch of atmospheric science. The science that studies the physical phenomena and processes in the atmosphere and their changing laws.

The research field of meteorology is very wide, and the research methods are also very different. Meteorology is divided into many branches: atmospheric physics, meteorology, dynamic meteorology, climate 3231313335323635438+034331363231363333333338+58688.

With the development of production, the application of meteorology is increasingly extensive, and applied disciplines such as marine meteorology, aviation meteorology, agricultural meteorology, forest meteorology and pollution meteorology have appeared one after another. With the application of modern science and technology in the field of meteorology, new branches have emerged, such as radar meteorology, satellite meteorology, cosmic meteorology and so on.

Meteorology is an applied science closely related to production and life, involving many disciplines. Edit this research task 1 to observe and study various atmospheric phenomena, the interaction between the atmosphere and the underlying surface and the meteorological effects caused by human activities.

2. Explain these phenomena, functions and influences systematically and scientifically, and clarify their occurrence and evolution laws. 3. Analyze, diagnose and predict the past, present and future weather according to the known laws.

Climate serves the national economy and people's daily life. 4. The weather process and artificial climate environment explored and simulated according to theory and practice provide scientific basis for artificially influencing weather and climate.

Editing this history The first person to establish meteorology was the ancient Greek philosopher Aristotle. He described and explained the weather phenomena such as wind, clouds, rain, snow, thunder and hail for the first time in the world's earliest meteorological book, Dynamic Meteorology, and the monograph "Meteorological Exchange Theory".

Until 18- 19 century, due to the development of physics and chemistry and the continuous invention of measuring instruments such as pressure, temperature, humidity and wind, atmospheric science research entered the stage of quantitative analysis from simple description. 1820, Budrin, a German, drew the first surface weather map, which initiated modern weather analysis and forecasting methods.

1835, French Coriolis put forward the concept of wind deflection; 1857, Dutch C. H. D. Buys Ballot put forward the relationship between wind and air pressure, and their concepts became the basis of atmospheric dynamics and weather analysis. Around 1920, Pierre Knies and his son put forward a set of theories called "polar front theory" to explain the weather changes in mid-latitude areas.

It has been more than 70 years since 1920s was published, but it is still the main theoretical basis for today's weather forecast, and it also lays a theoretical foundation for analyzing and forecasting the weather in the next 1-2 days. 1930 s, the extensive use of radiosondes really began the atmospheric science research in three-dimensional space.

According to the high-altitude weather map drawn by a large number of detection data, the atmospheric long wave was found. 1939, Rossby proposed long-wave dynamics, and his theory also made great contributions to weather forecasting.

1From 1950s to 1960s, with the application of computer, weather radar, satellite and remote sensing technology, all kinds of atmospheric phenomena, from atmospheric circulation to raindrop formation, can be expressed in physical and chemical mathematical forms, thus making atmospheric science develop by leaps and bounds. The embryonic stage of this editorial development mainly refers to the long period before the middle of16th century. The characteristic of this period is that due to the needs of military meteorology and human life and production, some sporadic and local meteorological observations have appeared, some perceptual knowledge and experience have been accumulated, and some weather phenomena have been explained.

During this period, China has made many achievements in this field and is in the leading ranks in the world. As early as 3000 years ago, there were written records about wind, clouds, rain, snow, rainbows, clouds, tornadoes and thunderstorms. In Jia Shu of Yin Dynasty, people often ask about the weather in the next ten days (called "insolence") and record the actual situation for verification.

During the Spring and Autumn Period and the Warring States Period, according to the observation records of wind, clouds and phenology, 24 solar terms can be determined, which is of great significance to guiding the agricultural production season in the Yellow River basin and has been used until modern times. During the Qin and Han Dynasties, books on phenology also appeared, such as Lu's Chunqiu, Huainanzi and Book of Rites, which are the earliest phenological documents in the world.

Meteorological observation instrument is also the earliest invention of China. In the Western Han Dynasty (BC 104), three kinds of anemometers, Dai, Tong Feng and Xiang Bird, were popular, but in the Tang Dynasty, Xiang Feng Bird was used in fixed places, and the army used anemometers made of chicken feathers.

It was not until the 20th century that Europe recorded the use of migratory birds to measure the wind. In the Western Han Dynasty, the moisture absorption characteristics of feathers, charcoal and other things were also used to measure the air humidity.

In the Song Dynasty, a monk Zanning (A.D. 10 century) used a soil carbon hygrometer to forecast sunny and rainy days. The record of precipitation is also the earliest in China. According to the records of the later Han Dynasty, every county and state under its jurisdiction reported the rain to the imperial court every year from beginning of spring to beginning of autumn. Since then, all previous dynasties have attached great importance to the rain in various places.

Therefore, China has abundant rainfall, many floods and droughts, and the longest history. Due to the needs of production and life, human beings urgently need to predict the future weather changes, and have accumulated a lot of experience in long-term observation practice.

These experiences are expressed in short verse for easy memory and use. This is a weather proverb. The weather proverbs in China are extremely rich, except for some feudal superstitions, which are mostly the crystallization of the working people's experience in observing the sky.

Huang Zifa's Xiang Colleen Chan in Tang Dynasty, Tian Wu Jia Xing edited by Lou Yuanli at the end of Yuan Dynasty and the beginning of Ming Dynasty, and Zhan Hou by Xu Guangqi at the end of Ming Dynasty are all works summarizing people's experience in weather forecasting. In foreign countries, meteorology sprouted very early. In the 4th century BC, the great Greek philosopher Aristotle wrote a book called Meteorology (about 350 BC), which comprehensively discussed water, air and earthquakes, and made an appropriate explanation for atmospheric phenomena.

Nowadays, the foreign names of meteorology are all evolved from Aristotle's original name. In short, in the embryonic period of meteorology, China and Greece had contact. At this time, from the disciplinary nature, meteorology and astronomy are mixed, but.

7. Do you have any scientific knowledge? About 50 words, the more the better.

1 When the seeds of almost all plants germinate in the soil, the roots always grow underground. Why is this?

In the past, people thought that the roots of plants grew underground because of the gravity of the earth. Later, after research, scientists found that the top of the root looked like wearing a "hat", called the root crown. A large amount of calcium is accumulated in the cells of root cap, which controls the underground growth of plant roots.

The attraction of water

Groundwater is also the reason that attracts roots to grow underground. In addition, roots tend to grow more densely in wet places. Don't say you don't know.

Some trees that grow in swamps have their roots sticking out of the soil. This is a special respiratory root, which can adapt to the environmental conditions of sludge hypoxia.

2□ The house next to the overpass

Interpretation of traditional environmental psychology: affecting wealth

Scientific explanation: the traffic is inconvenient, and the high-speed passing of vehicles will produce noise and spiral airflow, which will adversely affect physical and mental health. After years of clinical experience research, for some sensitive people, living in such a place is prone to neurasthenia.

3□ Houses next to high-voltage electric towers and TV towers

Scientific explanation: The transmission power of TV tower is very strong, and electromagnetic waves will lead to the decline of people's immune function. A house 300 meters away from the electric tower is generally better.

4□ House next to the gas station

Scientific explanation: Because the engine oil contains a lot of harmful substances such as lead, and the noise of vehicles stopping and starting next to the gas station is very loud, it is unsafe.

5□ The house opposite the glass curtain wall.

Scientific explanation: the light pollution caused by the reflection of glass curtain wall is not good for eye health, and it is easy to cause various eye diseases, such as glaucoma.

6□ A house facing the road.

Traditional environmental psychology explains: the house faces the road, "suffocating" and people are easy to catch a cold.

Scientific explanation: privacy is not good, and noise and dust pollution are relatively large.

8. What is the common sense of spring health care and how to regulate the body?

Women should pay attention to spring health care;

First of all, the law of life

When spring comes, the skin stretches, the peripheral blood supply increases, the sweat gland secretion also increases, and the load of various organs of the body increases, while the central nervous system has a sedative and hypnotic effect, and the limbs feel sleepy. Don't covet to sleep late at this time, because it is not conducive to the rise of yang. In order to adapt to this climate change, we should go to bed early and get up early in our daily life, often go for a walk outdoors, along tree-lined paths, and blend in with nature in the Woods.

The climate in spring is changeable, sometimes cold and sometimes warm. At the same time, people's skin is slack and their resistance to the outside world is weakened, so don't take off your thick clothes at once when spring comes, especially those who are weak.

Second, diet aftercare

In spring, human metabolism begins to flourish, and the diet should be spicy, sweet and mild.

Spring diet should avoid eating greasy and cold things, and eat more foods rich in vitamin B and fresh vegetables. Modern medical research believes that overeating and vitamin B deficiency are one of the reasons for sleepiness in spring.

Spring is a time when the liver is flourishing. Eating more acidic food will make the liver fire stronger and damage the spleen and stomach. You should eat more sweet foods rich in protein, sugar, vitamins and minerals, such as lean meat, eggs, milk, honey, bean products, fresh vegetables and fruits.

Third, the spirit of lifting feet.

People's spiritual activities must adapt to climate change. The human body is most affected by the seasons, especially at the turn of winter and spring. Some people can't adapt to the climate change in spring and are prone to mental illness. Modern medical research shows that bad mood can easily lead to stagnation of liver-qi, dysfunction of neuroendocrine system and decline of immune function, which can easily lead to psychosis, liver disease, cardiovascular and cerebrovascular diseases and infectious diseases. Therefore, in spring, we should pay attention to emotional health, maintain an optimistic and cheerful mood, make the liver qi unobstructed, and play a role in disease prevention and health care.

Spring and March are the seasons when everything begins to flourish. At this time, we should try to avoid being angry, not depressed, and be open-minded and optimistic. The body should be relaxed, comfortable, natural and full of vitality.

Fourth, exercise and maintenance.

After entering the spring, we should adapt to the characteristics of rising yang and strengthen physical exercise. We can go running, boxing, doing exercises, walking, playing ball games and flying kites in the fresh air, so as to let our bodies get rid of the old and welcome the new, stretch our bones and muscles, and lay a good healthy foundation for one year's work and study. Practice has proved that people who often take part in exercise in spring have strong disease resistance, quick thinking, anti-fatigue and high efficiency.

The origin and development of sports

As an important part of human culture, sports gradually formed and developed with the development of human society. According to the research of historians and archaeologists, as early as primitive times, human beings passed on walking, running, jumping, throwing, climbing and jumping as the most basic skills and abilities in productive labor and daily life to the next generation. This is the bud of human teaching and sports activities. The development of sports is closely related to the development of education, military affairs, science and technology, and people's religious activities and leisure activities. It must be pointed out that in the whole historical development process, sports are restricted and served by certain political and economic conditions. The development of sports has roughly experienced the following three periods: the embryonic period of primitive sports; Consciously engaged in sports period; The formation and perfection period of sports system. After these three periods, the modern sports system gradually formed; Among which competitive sports
