Poems about the beginning of popular science articles 1. What are the wonderful beginnings of popular science articles

(1) Scientific nature Scientificity is the lifeblood of all scientific and technological works, and popular science works are no exception.

Science must reveal the objective laws of things, explore objective truth, and serve as a guide to understanding the world and transforming it. Popular science works are responsible for popularizing scientific knowledge and enlightening ideas to the public, and they should ensure scientificity.

Popular science works that lose their scientific nature will also lose their existence value. Therefore, creators of popular science works should try their best to explore their own professional strengths, start from the fields they are familiar with, and use a comprehensive development perspective to introduce mature and practical knowledge to the readers.

(2) Ideology Popular science is a bridge between science and technology and social life. While imparting knowledge to readers, it also enables readers to be influenced by scientific ideas, scientific spirit, scientific attitude and scientific style, and promotes scientific worldview and methodology to improve people's scientific quality and ideological quality.

Therefore, popular science works should introduce scientific knowledge through popularization, so that people can deeply understand the scientific worldview methodology, that is, materialism and dialectics. This is the embodiment of the ideological nature of popular science works.

Of course, the ideological nature of science popularization creation is intrinsic and naturally expressed in the works, rather than affixing some political labels or adding some external political terms. (3) Popularity Popularity means introducing scientific and technological knowledge in clear and concise words to make it vivid and easy to understand.

"The entire process of popular science creation is actually the process of popularizing specialized knowledge." ("Introduction to Popular Science Creation" edited by Zhang Daoyi and others, Peking University Press, 1983 edition, page 38) This sentence The words illustrate the essence of popular science creation.

If scientific knowledge is not expressed in a popular way and readers cannot understand it, it will not play the role of science popularization creation, and science popularization creation will lose its meaning. Popular science creation can use a variety of methods to popularize science works.

If you use literary and artistic forms to create it, make it lively, interesting and fascinating. But this is not the only way. Popular science works can be popularized as long as they are concise, explain the profound things in simple terms, written clearly and connected with people's actual life and work.

Avoid simplification, vulgarity, or simplification that is incomplete, just going around in abstract concepts; or piling up information, copying it, or turning popularization into vulgarity to cater to vulgar taste. These are all It should be avoided in popular science creation. (4) Artistry is a characteristic derived from popularity. The popularity of popular science works often requires the use of literary and artistic forms to introduce scientific and technological knowledge. In the creative process, not only logical thinking is used to achieve the effect of convincing people with reason, but also image thinking is used. , making it moving with emotion.

(5) Knowledge 2. Techniques of popular science creation Popular science works are different from other scientific papers in that they can use a variety of expression techniques to make them easy to understand and engaging. Here are some common creative techniques.

(1) Propositions in popular science works include direct narratives, such as "Smoking is very harmful to teenagers"; interrogative styles, such as "Will calcium deficiency in children affect intelligence?"; aphorisms, such as "Climate "Zonghengtantan - the universe, the sun and the moon" story style; such as "talking about leukemia from "Blood Doubt""; metaphorical style, such as "the 'doctor' of plants - Woodpecker"; in addition, there are also allegorical, enlightening, Idioms and other proposition methods. (2) Beginning Techniques for beginning popular science works include starting with a vivid story; starting with a thought-provoking question; getting straight to the point, starting with a topic; descriptive opening; argumentative opening, etc.

For example: "How far away is AIDS from us?..." It starts with a question. In "No Bridge That Can't Be Built" by Mao Yisheng, he gets straight to the point: "Roads are made by people. When there is a road, a bridge is needed. Where there is a road, there will probably be a bridge.

People need bridges, and people can also build bridges.

As long as there are roads that can be built, there are no bridges that cannot be built.

…” Let’s look at Qin Mu’s “Sewing Shells on the Beach” again. At the beginning, he uses descriptive words to bring us to the seaside with alluring scenery: “In artistic photography, we often see such scenes. : On the endless beach, a person is leaning over to pick something up; there are clouds floating in the sky, and waves are splashing in the distance..." (3) Ending The ending of a popular science work should be as evocative as a literary creation, and should be memorable. It corresponds to the beginning of the article. The methods include concluding endings, inspiring implicit endings, encouraging endings, and anaphoric endings. No matter which ending method is used, the text must be concise.

For example: "It is estimated from this that the population limit on the earth is 8 billion. If it exceeds 8 billion, eating will become a serious problem. Therefore, it is natural to open the ‘insect granary’. "

This is the concluding ending. There is a popular science article titled "The Road to Health and Longevity" which firmly believes in the causes of aging, anti-aging and life-extending measures and their mechanisms of action.

“...If you are good at combining the valuable experience left by the ancients with modern life sciences for research, you will surely be able to find a correct way to resist aging and prevent aging, so that more people can achieve health and longevity... "This kind of encouraging ending can infect readers' emotions and inspire them to devote themselves to science.

In addition to these techniques, the following techniques can also be used in the writing process: (1) Contrast Some things and principles are relatively abstract and profound, and are difficult for readers to understand. The author can then find some comparison objects that are similar or relative to the object of expression, are relatively simple, concrete, and familiar to the readers, and compare them with the object of expression. , explain the relationship between them clearly.

In this way, the things or principles to be expressed will be reflected in a popular and clear way, and it will be easier for readers to understand. For example, this paragraph "Atoms are really small. Extremely... five hundred thousand to one million atoms, lined up one after another in a "long snake line", are only as small as the diameter of a hair. "The comparison method is used to vividly express the "smallness" of atoms.

(2) Metaphor is different from comparison. The two objects of comparison have some kind of essence. *The same thing, and the two things in metaphor are completely different in nature, except for some similarities. Metaphor is to use these two similar objects to vividly display the things that are really meant to be expressed through analogies. Or principles.

But it should be noted that the things used in metaphors should be specific. Usually, concrete images are used to describe general abstract principles, familiar things are used to describe unfamiliar things, and simple principles are used to describe profound things. Reason.

Such as "Just.

2. Articles about popular science

Hello:

Two new fossils were found in China. They are fossils of dinosaurs. The kind os dinosaurs lived 160 million years ago. They are about 3.6 feet tall and 9.8 feet long. Scientists think they are a group of small, meat-eating dinosaurs, with a crest on their head.

They arenamed Guanlong Wucai in Chinese ."Guanlong" comes from the crest. People belive the crest isn't for fight but just for show like the peacock.

"Wucai" comes from the rich color of the crest. Scientists guess there are also some feathers on the crest and this makes them think of birds. Maybe they had something the same as birds at the beginning.

Studying the fossils, from the size of them, the stronger legs and the crest, scientists are almost sure they are from the tyrannosaurs family. But they are much smaller than tyrannosaurs. Tyrannosaurs are best known from 70 million years ago. if it is true, we will say tyrannosaurs were not born in North America.

Sorry for my incompetence, I could only find this article, and I'm deeply sorry!

Popular science poems (1) 1. The light and heat of the sun Why is the sun so bright? Where does its heat energy come from? It turns out that the hydrogen gas in its body becomes lazy under high temperature and pressure. (Note) The thermonuclear reaction releases huge energy, which emits heat and light. The rich hydrogen makes it glorious for five billion years. Five billion years later, The sun is still the same as it is now! Note: The hydrogen element in the sun turns into the helium gas under high temperature and pressure, and releases a large amount of energy at the same time. Why does the sun shine and heat? No one knew about this before. It turns out that the hydrogen element it is rich in combines into helium nuclei under high temperature and pressure. The thermonuclear reaction releases huge energy, and the huge energy emits light and heat. The hydrogen of the sun can make it brilliant for five billion years. , it is still glowing five billion years later.

6. A popular science article

A few days ago, I bought a little goldfish. It is so cute.

The little goldfish is silver-gray all over, with two bulging eyes like small light bulbs. The most endearing thing is that it is wearing a trumpet skirt. As it swims, this "flare skirt" looks like a blooming lotus. I really like it.

Every time I come home from school, the first thing I do is to feed the little goldfish. When I was about to sprinkle the food to it, it seemed to know that I was going to feed it, so it swam toward me. I sprinkled the fish food on the water little by little, and the little goldfish ate it one bite at a time. After it had eaten and drank enough, it swam freely in the water. At this time, a question suddenly flashed in my head, why can fish only live in water? I really wanted to understand this question, so I asked my mother, and she only told me that fish breathe through gills.

Can fish live in water by breathing through gills? I decided to go online and find out. Nowadays, technology is so advanced that I soon found the answer.

It turns out that the gills of fish are only adapted to absorb oxygen from the water, but cannot absorb oxygen from the air. In addition, the shape of the fish is more suitable for life in the water. The surface of its body is covered with scales to protect its body. There is a layer of mucus on the surface of the scales, which can reduce the resistance of the water when swimming. No wonder, every time you pick it up with your hands, it feels slippery.

There is also a line of lateral lines on both sides of its body, which are connected to nerves and are mainly used to determine direction and sense water flow. In addition to swimming "tools" such as pectoral fins, dorsal fins, pelvic fins and tail fins, fish also have swim bladders in their bodies. By adjusting the air volume in the swim bladders, they can float and sink freely in the water.

I finally understood why fish can only live in water, and it also satisfied my curiosity. From now on, I like my little goldfish even more! Every time I see it swimming freely, I fall into endless reverie: If one day people also have gills and a swim bladder in their bodies, then they can swim freely in the water like a small fish.

What a magical thing that would be! Back.
