2. Little scientific knowledge

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. 3。

Why can snakes walk without feet? Snakes have many scales, which are the outermost armor on their bodies. Scales are not only used to protect the body, but also to be their "feet".

When a snake crawls forward, its body will be S-shaped. Every scale outside the S-shape will tilt upward to help the snake catch the uneven road when it moves forward.

These scales cooperate with the muscles of the snake and can push the body forward, so the snake can walk without feet! 4。 Why do sunflowers always bloom towards the sun? There is a substance called "auxin" in the stem under the sunflower disk.

This substance has the function of accelerating replication, but it is anti-optical, and it will run to the backlight side whenever it encounters light. So when the sun rises, the stem of the sunflower immediately hides to the side of the backlight, as if the whole plant is bent in the direction of the sun.

5。 Why does the hair turn white when people are old? There is a substance called melanin in our hair. The more melanin, the darker our hair will be.

Without melanin, hair will turn yellow or white. When human beings reach old age, various functions of the body will gradually decline, and the formation of pigments will be less and less, so the hair will gradually turn white! 6。

Why do fireflies glow? Fireflies emit light because there is a luminous body at the end of their abdomen, which is filled with a lot of phosphorus-containing luminescent substances and luminescent enzymes, so that fireflies can emit flashing light. The purpose of fireflies is not only lighting, but also courtship, vigilance and trapping.

This is also a communication tool for them. Different kinds of fireflies emit light in different ways, frequencies and colors, so they can convey different information. 7。

Why do you growl when you are hungry? When you are hungry, you will purr. This is because the food you have eaten before has almost been digested. Although the stomach is empty, the gastric juice in the stomach will continue to secrete. At this time, the contraction of the stomach will gradually expand, and the liquid and gas inside will be stirred up and purr.

Don't be embarrassed by your stomach growling next time! Because this is a normal physiological action. 8。

Why can't ostriches fly? A giant ostrich, but they can't fly into the sky! This is not because their wings are useless, but because their feathers are too soft and their wings are too small to fly at all. In addition, the ostrich's muscles are underdeveloped and its sternum is flat, which is not conducive to flying.

Ostriches live in Africa. Because they have lived in desert areas for a long time, their bodies gradually evolved into what they are now in order to adapt to the environment. 9。

Why can't it go bad easily? Lunch meat, black bean shad, tomato sauce beans.

They are all delicious canned food, which can be preserved for a long time without deterioration. This is because the can is sealed, so bacteria can't enter.

When people make canned food, they pump all the air out of the canned food and then seal it. In the absence of air, even if the food inside is contaminated with a little bacteria, they can't survive or reproduce! 10。

Why do babies always cry at birth? Babies cry when they are born, not because they are unhappy, but because they are taking the first breath of air! When babies leave their mother's body and are born, the first breath of air will rush to their throats, violently impact the vocal cords, make them vibrate, and then make a sound similar to crying. 1 1。

Why do lizards keep playing backwards when their tails are broken? In order to protect themselves, many lizards also protect their eyes and ears; When some lizards are attacked, their tails will be broken due to the severe contraction of their muscles. Because there are still some nerves alive in the broken tail, it will keep bouncing, thus distracting the enemy and running away.

Why can't a person's thumb have one or three knots? The average person has five fingers, each with a different length. However, does anyone realize that besides the thumb, other fingers also have three sections, while the thumb alone has only two sections?

However, when you pick up the sea water, you can only see it as transparent and colorless as old water. Original.

Step 3 explain common sense

Common sense of expository writing 1. The concept of expository writing: expository writing is a style with explanation as the main expression, or introduces the state, nature and function of things (expository writing); Or make things clear, the purpose is to give people knowledge (explanation of things).

Second, explain the common sense of the text: 1, explain the object: introduce things, clarify things 2, explain the characteristics: the essential things that are different from other things 3, explain methods: give examples, enumerate numbers, classify, compare, analogy, quote, define, explain, draw tables, imitate appearances, etc. 4. Interpretation sequence: time sequence, spatial order. Classification of exposition: from the object: things exposition, events exposition; From the language: vivid exposition, plain exposition. Nine common explanations: 1. Explain the situation or events of things, sometimes just from the perspective, people don't quite understand. This requires some examples that are both easy to understand and representative. Function: concretize and clarify more complicated things.

For example, in the article "Language of Nature", in order to illustrate "the influence of latitude position on phenology", the author cited the flowering time of peach blossoms and Robinia pseudoacacia in Nanjing and Beijing to illustrate. 2. Classification should not explain the characteristics or events of things. It is often not easy to make it clear unilaterally. According to the similarities and differences of things or events in form, nature, causes and functions, things or events can be divided into several categories according to certain standards, and then explained one by one according to the categories.

Function: Explain things or things in an orderly way. 3. Enumerate numbers: Numbers are the most accurate, scientific and convincing basis for quantitatively explaining the characteristics or reasons of things.

Function: Tell things accurately and intuitively. For example, the article "Palace Museum" introduces that the Hall of Supreme Harmony is "28 meters high and covers an area of more than 2,380 square meters", which is a typical explanation method of enumerating figures.

4. Comparison In order to make things easy to understand, we can sometimes compare familiar things or things in people's lives according to people's existing perceptual knowledge, thus stimulating readers' imagination and gaining a deep impression. Function: concretize abstract or unfamiliar things or things and make them easy to understand.

For example, in the article "Suzhou Gardens", the author compares the characteristics of Suzhou Gardens with those of Beijing Gardens, indicating that they seldom use colored paintings. 5. Definition In order to highlight the main content or problems of things or things, things are often defined in concise language.

This is a way to explain the characteristics or reasons of things and reveal the essence or reasons of things. Function: Explain things accurately, concisely and generally.

For example, the article "Wonderful Cloning" scientifically explains cloning, that is, it is defined as "not only refers to asexual reproduction, but also refers to a group that originates from an ancestor and asexual reproduction, which is called cloning". 6. Metaphor is a metaphor in rhetorical methods.

Using analogy in expository writing can make things that people don't understand or abstract concrete, vivid and vivid. Function: Things or abstract things become concrete, vivid and vivid, highlighting the characteristics of things.

For example, in "China Stone Arch Bridge", the bridge hole of the stone arch bridge is curved, just like a rainbow, so that readers can understand the characteristics of the stone arch bridge more vividly and clearly. 7. Draw a picture. Some things are abstract and complicated, and it is impossible for readers to understand them just by words. This requires attaching a schematic diagram or drawing a chart accurately in proportion, such as product design drawings and military action road maps.

Sometimes, there are many things that need to be explained, and you can also make statistical tables and fill in the relevant figures separately, so that people can see at a glance. Function: Tell things accurately and intuitively.

8. Explain this is a way to explain things. The difference between definition and explanation lies in that definition requires completeness, that is, the object of definition should be equal to the extension of definition, and the whole connotation of concept should be completely revealed from one aspect; However, the explanation does not require completeness, as long as part of the connotation of the concept is revealed, and the object of explanation and the extension of explanation are not necessarily equal.

For example, the definition of "a word is the smallest language unit that can be used independently" can be reversed, that is, "the smallest language unit that can be used independently is a word". And "uranium is silvery white metal" is an interpretation, and it cannot be said that "silvery white metal is uranium". For example, at the turn of autumn and winter, in clear Wan Li, the temperature at a certain height is inversely proportional to the low and high.

This is called "inversion layer", which is an explanation. 9. Imitation reveals the characteristics of things through specific descriptions.

Function: It helps to make the explained object more concrete and vivid. For example, the article "China Stone Arch Bridge" wrote: "Some lions in these stone carvings are hugging their mother and son, some are whispering, and some are like listening to the sound of water, which is changeable and lifelike."

This is very lively. 5. Order of interpretation: 1. Time sequence: that is, arrange the order of explanation according to the time when things happen and develop, so as to write down the development and changes of things.

This order is generally used for biographies, scientific observation records, and explanatory words to explain the occurrence, development or production process of things or events. 2. spatial order: that is, according to the spatial existence form of things, from outside to inside, from top to bottom, from front to back, or from far to near.

This order of interpretation is generally used to explain the shape and structural characteristics of things. 3. Logical order; That is, the order of interpretation is arranged according to the internal relationship of things or things and the process of adults understanding things.

The internal relations of things include causality, progressive relationship, primary and secondary relationship, total score relationship, juxtaposition relationship and so on. The process of understanding things or things refers to from shallow to deep, from concrete to abstract, from phenomenon to essence, from performance to function, from general to special, from whole to part and so on. Layer by layer, the logic is clear.

Sixth, the language of expository writing: the accuracy of expository writing language is the premise of expository writing language. Time, space, quantity, scope, degree, characteristics, nature, procedures, etc. All require accuracy.

The explanation is practical. A slight mistake is a drop in the bucket. Special attention should be paid to the terms and restrictive words used in the interpretation text, which often reflect the accuracy of the interpretation language.

On the premise of accuracy, there are some linguistic explanations.

4. Give examples to illustrate the relationship between psychology and common sense.

We live in all kinds of hints. For example, advertisements make people remember it with bright colors and various sounds, and it is easier to buy when shopping. As for hypnosis, for example, if you go to the movies and you are sweating, then you are hypnotized by the movies. For example, when you say your name and age when you meet for the first time, the other person will also say your name and age. If you just say your name, for example, if someone asks you if it's a hint, you give a yes or no answer. There is a hint that is closest to common sense, that is, red light gives people blood and fire, which is why it is used as a stop sign. You will get what you pay in communication. Finally, I am a high school student. Please forgive me for saying something wrong.
