Read the answer to flying snowflakes

Ahem, snowflake dance is actually a piece of music.

① Snow

Beautiful snowflakes are flying. I haven't seen you for three years. Last year, in Fujian, it seemed a little later than now, and I saw snow, but it was snow on the top of the mountain in the distance, not flying snowflakes. On the plain, it is just a few accidental raindrops. When it doesn't land, its color is gray, not white; Its weight is like raindrops, and it can't fly. As soon as it landed, it immediately melted into water, without trace, jumping or making a rustling sound, just like when it snowed in Jiangsu and Zhejiang. This kind of snow, the first time I saw the old Fujian people in 40 years, can really feel particularly strange and talk about it with relish, but in my opinion, it always feels boring. "It snows in Fujian", I don't think so.

I like the snowflakes flying in front of my eyes. It is "snow-white" white, as beautiful as a flower. They seem to be lighter than air. They didn't fall from the air, but were rolled up from the ground by the air. However, it is a living creature, just like swarms of gnats at dusk in summer, just like bees in the honey gathering period in spring. It is busy flying, up or down, fast or slow, or sticking to people, or squeezing into gaps, as if it has its own will and purpose. It is silent, but when it flies, we seem to hear the cries and footsteps of millions of people, the stormy waves of the sea, the roar of the forest, and sometimes it seems to hear the whispers of children, the quiet evening prayers in the chapel, and the cheerful birds in the garden ... It brings gloom and cold; But in its flying posture, we seem to see a charitable mother, a lively child, a smiling flower, a warm sun, a silent sunset ... It has no breath, but when it hits us, we seem to smell the fresh air in the wilderness, elegant orchids in the valley, heavy roses in the garden, and faint jasmine flowers ... During the day, it blooms in various ways. At night, it gives off silver light, shines on people walking on the road, and draws all kinds of flowers and trees on our glass windows, oblique, straight, curved and upside down, as well as rivers and clouds in the sky. ...

② Snowflakes

Beautiful snowflakes are flying. I haven't seen you for three years.

Last year in Fujian, it seemed a little later than now, and I also saw snow. But that's snow on the top of the mountain in the distance, not flying snowflakes. On the plain, it only occasionally sprinkles a few drops with the rain and never falls to the ground. Its color is gray, not white; Its weight is like raindrops, and it can't fly. As soon as it landed, it immediately melted into water, jumping or sighing without trace, just like when it snowed in Jiangsu and Zhejiang. This kind of snow, the old Fujian people I met for the first time in 40 years, can certainly feel special significance and talk about it with relish, but in my opinion, it is always boring. It snows in Fujian, but I don't think so.

I like the flying snowflakes in Shanghai. It is "snow-white" white, as beautiful as a flower. It seems to be lighter than air, not falling from the air, but being rolled up from the ground by the air. However, it is like a living creature, like a group of gnats at dusk in summer, like bees in the honey gathering period in spring. Its busy flight, up or down, fast or slow, or sticking to people, or squeezing into gaps, seems to have its own will and purpose. It is silent. But when it flies, we seem to hear the cries and footsteps of millions of people, the rough sea, the roar of the forest, and sometimes it seems to hear the whispers of children, the quiet evening prayers in the chapel, the cheerful birds singing in the garden ... It brings gloom and cold. But in its flying posture, we saw a charitable mother, a lively child, smiling flowers, warm sun, silent sunset ... it didn't breathe.

But when it jumped on our faces, we seemed to smell the fresh air in the wilderness, the elegant orchids in the valley, the rich roses in the garden, and the faint jasmine ... During the day, it made thousands of beautiful gestures; At night, it gives off silver light, shines on our pedestrians, and draws all kinds of flowers and trees on our glass windows, oblique, straight, curved and upside down. And the river, the clouds in the sky …

The Secret History of Snowflakes

Liu Yangyang

16 1 1 Christmas, the impoverished German astronomer Kepler wandered the streets. Royal scientists are depressed. He hasn't been paid for several months, and he is racking his brains to think about how to give gifts to his friends. He looked at the snowflakes flying all over the sky and sighed, "Oh, my God! What else can I send besides snowflakes? "

Of course, snowflakes can't be sent to each other, but the talented scientist has a sudden idea: he is determined to write an article about the shape of snowflakes as a New Year gift for his friends. So this paper entitled "On Hexagonal Snowflakes" came out. For 400 years, whenever we talk about snowflake research, we will be the first to promote this academic paper born of poverty and friendship.

Astronomers' observations are informal after all. Twenty years later, the mathematician and philosopher Descartes first described the shape of snowflakes in detail. Like Kepler, the scientific giant's observation is limited to the naked eye. However, his eyes are unusual. In addition to different hexagons, he also recorded extremely rare snow flakes with capped ice prisms and dodecahedron structures.

In the observation notes, Descartes praised: "Perfect hexagon! The edges are so straight and the angles are so equal that clumsy humans can't do it ... I can't imagine how these completely symmetrical hexagonal elves were born leisurely in free air and manic wind. Gee, maybe Fengshen ordered the elves to fly up and down the clouds and put their light bodies there; Let them look around in time, follow the inspiration of the inherent order of nature and polish themselves into hexagons! "

The time machine keeps running. In the snowstorm of1885 65438+1October 15, Bentley took the first microscope photo of Zhang Xuehua. This kind of "snowflake macro photo" comes from a camera box connected to a microscope in the ice and snow. Later, he published an article saying: "Although shooting snowflakes is a meticulous job, it is not difficult. The difficulty is that this work must be carried out at sub-zero temperatures and the body needs to be exposed to cold. " In the following decades, "Snowflake Crystal Photographer" took more than 5,000 photos of Zhang Xuehua, and each photo was different.

After learning snowflakes, waves push forward waves. Today, Snowflake is Kenneth Lieber Brecht of California Institute of Technology. The physicist let snowflakes fall on the collecting board, and then observed them carefully to find interesting samples. He found that the most perfect snowflake crystals often appeared in snowy days with low winds, when the weather was particularly cold. To this end, he often goes to the cold northern region to wait for snowfall.

In addition to hexagonal snowflakes, exotic triangular snowflakes are common crystal forms of snowflakes in nature. In order to solve this mystery, Lieber Brecht and his collaborators simulated conditions similar to natural snowfall in the laboratory to make snowflakes, and recorded snowflake crystals with different shapes.

The final result shows that some triangular snowflake crystals still have six faces. They look triangular because they are composed of six sides with three long sides and three short sides.

Lieber Brecht pointed out that in the process of snowflakes falling from the sky, tiny dust particles and other impurities will cause one side of snowflakes to tilt. Under the action of wind, the downward hypotenuse will grow faster, thus forming a triangle. Once the triangle begins to form, due to the stability of the triangle, the snowflake will continue to fall, even if it encounters bumps and collisions again, until it falls to the ground.

In 2006, Lieber Brecht's photos of snowflakes were made into stamps and floated all over the world, including those corners where it never snows.

Nowadays, scientists are studying the atmospheric conditions that can lead to the formation of huge snowflakes, which is very important for climate research. It is said that the largest snowflake in the Guinness Book of Records appeared in a snowstorm in Montana, USA. A local farm worker said that this kind of snowflake is bigger than a milk pot, with a diameter of about 38 cm. Unfortunately, there is no relevant evidence to support his statement. (Excerpted from China Youth Daily, with deletion)

19. This paper lists many scientists' research on the riddle of snowflakes. Please sum up what scientists have done to explore the mystery of snowflakes. (4 points)

20. Popular science language is not only accurate and rigorous, but also has language characteristics different from general expository texts. Please enjoy the underlined sentences in the text (5 points)

2 1. In the article, Bentley said: "Although shooting snowflakes is a meticulous job, it is not difficult. The difficulty is that this work must be carried out at sub-zero temperatures and the body needs to be exposed to cold. " In order to take more photos of snowflakes, he finally died of pneumonia in the cold. Combining words with reality, what did Bentley's experience bring you? (6 points)

19.( 1) German astronomer Kepler first proposed that snowflakes are hexagonal in the form of academic papers. The philosopher Descartes described the shape of snowflakes in detail for the first time and recorded two extremely rare snowflake shapes. (3) Bentley took a macro photo of snowflakes and found that each snowflake had a different shape. (4) Physicist Lieber Brecht unveiled the mystery of triangular snowflake crystals. (65438+ 0 point per point)

20. The language of underlined sentences is vivid. It uses figurative and anthropomorphic rhetoric to compare snowflakes to elves, and endows snowflakes with human actions and emotions, such as "living leisurely", "looking around" and "thinking of oneself as a hexagon". It imagines the process of snowflake forming hexagon with perceptual language, vividly shows the infinite mystery of snowflake shape and fully expresses the author's understanding of snowflake. (Answer a statement and analyze 2 points; Five points for both statements. The meaning is right)

2 1. Example1:(1) It is said in the article that Bentley was not afraid of the cold and ignored life and death in the process of studying snowflakes. This love and pursuit of science is touching. In my opinion, our life should be like Bentley, persistently pursuing what we love and working hard for it. I believe that this hard work will benefit us for life. For example, Yuan Longping, in order to pursue his rice dream, worked in the fields day after day, not afraid of being dirty and tired, and was willing to be a farmer, but solved the food problem that plagued hundreds of millions of people around the world and won the respect of people all over the world. Therefore, infinite love and persistent pursuit can create the brilliance of life.

Example 2: ① It is mentioned that Bentley paid the price of his life for studying snowflakes, which shows that scientific research needs extraordinary efforts. In my opinion, if you want to surpass the limited and mediocre life, you must also pay, and no one can succeed casually. Now many young people in the entertainment circle can't eat hard and are very tired. They always want to gain fame and fortune through some kind of "show". How can the fame and fortune gained in this way last? Only by hard work, diligence, hard training of basic skills and self-cultivation can your life really shine. (Combined with text explanation, 2 points. Feeling, 2 points. Analysis with real life examples, 2 points. Requirements: ① It is best to talk about "sentiment" at the beginning of the paragraph, and be sure to make it clear. (2) Examples should be appropriate, that is, examples should be based on their own feelings and opinions, and examples should be based on real life, including personal experiences, social phenomena and real events.

I hope this helps.
