Or fly into reeds or rice fields and be covered by branches and leaves; So the pursuer lost his goal and hesitated to change direction and flew away. Sometimes I give another firefly as a chasing target. And there are often more than one pair of such chases, so on the water and rice fields, like the stars in the sky, there are countless white lights flashing up and down; Especially on the water, there are wrinkled silver waves, which are very interesting.
This is what I saw in the countryside during my childhood and summer vacation. At that time, while listening to the neighbors who had worked hard all day in the hot sun, in order to get a rest at this moment, they sang simple nursery rhymes to fireflies:
Fireflies,
Red at night;
Fly to the sky to catch aphids,
Fly to the ground to catch green onions.
In this kind of song, occasionally a few people fly to the side and pat them with a banana fan. Sometimes they shoot on the ground. Sometimes it suddenly darkens and flies out of the range that the fan can shoot. At this time, even if you catch up, you often can't shoot anymore. It's really hard to find things that are photographed on the ground with hidden light; Or fly quietly, reproduce its light, and often give it escape. At first, the arrested person used it to bet on the outcome, that is, put it on the ground, drag it with his feet, and draw a glowing line on the ground. Comparing which one is drawn longer, it is regarded as victory. Needless to say, this is a cruel act. What do you mean? Life? Yes Later, those lucky individuals won't die in this way. They are sealed in duck egg shells prepared during the day, making them twinkle like small lanterns. I take it to my pillow when I sleep. I love to play and can't put it down. However, adults think that fireflies will go in and eat brains whenever they have the chance to get into people's ears, so it is often forbidden to bring them into the room.
How fireflies occur is not discussed in rural areas; But ancient books say it's made of weeds. Last year, the old magazine, known as the first in China, published Dr. Luo Guangting's biochemical theory, so it is probably reliable to turn rotten grass into fireflies. However, Dr. Luo has not written the following article until now after being invited by professors from several universities in Guangdong to do rigorous experiments. At least that old magazine never published his experiments again. Generally, Dr. Luo has been contacted by them. Then it is necessary to re-evaluate the legend of rotten grass and ignorance.
It turns out that there are many kinds of fireflies, and there are 2000 kinds of fireflies that can shine all over the world, all of which are similar in shape.
And there are 2,000 kinds that can't emit light. The most common here is yellow, and the tip of the wing is a little black. They also have men and women. After marriage, men think that their responsibilities have been fulfilled and then die. Female fireflies laid three or four hundred tiny spherical yellow-white eggs in the rhizosphere of weeds near the water, and then died. This egg can also give off some light. After 27 or 8 days, it hatches into larvae. The larva's body has thirteen sections, long spindle-shaped and slightly flat. The head and tail are black, and there are black spots on both sides of the body. There is an accessory at the end that can absorb other things and can be used instead of feet. There is also a special light-emitting organ on both sides of the body slightly in front of the tail, which can also emit cyan light. Japan and China lurk under the soil and come out for food at night. It can eat a snail, which is the intermediate host of human lung leech, so it has considerable benefits. Next spring, when I grow up, I will dig a small hole in the ground and take off my skin and pupa. Pupa is light yellow and can glow at night. In summer, it will become a flying adult. After reading this simple life history, the legend that rotten grass is a firefly can be broken.
Where did the most interesting fireflies come from? In scientific research, it used to be thought that luminescent bacteria and fireflies lived together in a certain place, but recently, after detailed research, it was determined that there were no traces of bacteria or chemical effects. The structure of this light-emitting device varies with the species and development time of fireflies. Larvae and pupa are generally similar;
On the ventral surface of the adult, usually located at the tail end, the surface is a pale yellow transparent dura mater, under which most neat cells are arranged to form a flat disk, and most yellow fine particles in the cells are called? Fluorescent body? (luciferase), which reacts with oxygen and emits light. These cells are surrounded by capillaries, which are connected to the trachea and can transport air and make the phosphor contact with oxygen. There are also many nerves, which can regulate qi transport at will, so they appear flickering. Corresponding to the luminescent cells, there is also a layer of small crystal cells containing most formate or urate, which is milky white, like a mirror and can reflect light outwards.
Fluorescent lamps do not contain red lines (hot lines) and ultraviolet rays (chemical lines), so they only have light without heat, so they are ideal lighting lights. But now humans still can't understand the content of these phosphors; We can neither use it directly nor imitate its chemical composition to make artificial fluorescence. What humans can use is Che Yin of Jin Dynasty, who put it in a bag and studied by candlelight. Abroad, Mexico produces a huge firefly with two big luminous bodies on its chest, which emit green light; There is also a luminous body below the abdomen, which emits orange light; The two colors set off each other very beautifully. Women put it in their hair as an ornament for dancing at night. Besides, it's just for fun. As for the firefly itself, it can lure the opposite sex and intimidate the enemy, which is very meaningful to its life.
In Shanghai where electric lights, gas lamps and neon lights complement each other, there is no chance to meet fireflies. I haven't seen fireflies in my hometown for a year or two or nearly ten years. Recently, my family wrote that it didn't rain in March, all the rice in the field died, and many mulberry trees withered. Then, of course, the pool of water we used to see dried up, a paddy field must look like a scorched earth, and the shadows of trees must be sparse. Hard-working neighbors have no work to do and can have a long rest, but I don't know how much laughter they can smell while enjoying the cool.
Because of fireflies, I think of my hometown suffering from drought. Bless my hardworking neighbor, who should have a way out.
Red candle
In order to decorate this sad New Year's Eve, my friend bought a pair of red candles from the market.
When you strike a match, it is lit, and its light immediately splits the darkness and scratches the dark net sunk in the corner.
In the jumping flame, we looked at each other's flushed faces, just because of this light, our hearts felt warm.
However, this bare outdoor wilderness has endured cold, relentless freezing rain, rolling wind on the ground and the weight of the night in recent days. It is silent and silent, like a mythical suffering giant.
The red candle is still burning, and its light is getting bigger and bigger. It endured the pain of suffering alone, causing its own doom, but it shone the light on the world. We looked at each other happily. Although we don't jump freely in the light like children, our hearts are so happy. It makes us forget the cold, forget the wind and rain, forget the night; It only leads us to the realm of peace, remembering that childhood, that innocent day, loving others with a pure heart and hating with that innocent heart. Weave an ideal world with children's thoughts. Why are there such minions as tigers and wolves? Why are your eyes red? Why is there bloodshed and death? Can't adults live in love?
But suddenly, a gust of wind blew out the burning red candle from nowhere. Attacked by this unfortunate accident, the memory of the child's dream disappeared, and my friends and I were silent, just holding hands tightly. Darkness filled the room again, the wind kept blowing in, and the cold rain blowing obliquely seemed to fall on my face and hands a little. Melancholy hung over me, and I still stared at the twilight of the embers, and finally it sank into the darkness silently.
Mr Lu Xun
The vase in Mr. Lu Xun's home is like a bottle used by western women to draw water in paintings. Gray-blue, with a little grain of natural accumulation of porcelain oil. There are two bottle ears on both sides of the bottle mouth, and several evergreen trees are planted in the bottle. When I first saw this plant, I asked: What is its name? The first time I walked into Lu Xun's house, there was no stove and I didn't freeze to death. It was near dusk and winter, and the room downstairs was a little dark. At the same time, when Mr. Lu Xun's cigarette left the corner of his mouth and stopped at the corner of the table, the curl of the smoke ring pattern rose to the height of his white hair. And if it goes up again, it will be out of sight. ? It's called. Evergreen tree? , forever! ? He shook off the cigarette ash in the ashtray next to the vase, and the red fireworks became redder, like a small flower, at a distance from his cuff. ? Not afraid of freezing after the flower, I asked again, but I can't remember when.
Xu teacher said: No fear, the most durable! ? She shook the bottle mouth for me. I also saw that the bottom of the flower was a round stone. Later, I saw it once or twice because I was familiar with it. In addition, this flower is always placed on the long black table in the living room. I am a northerner in the frigid zone. I'm always a little surprised at this plant that doesn't wither all the year round. Now this? Evergreen tree? Still alive, every time I go to Mr. Xu's house to see flowers, sometimes I stand on a long black table, and sometimes I stand in front of Mr. Lu Xun's photo. The vase was changed and put in a glass bottle, and the pale yellow fibrous roots were visible and stood at the bottom of the bottle. Sometimes xu teacher will chat with us and check all the flowers and plants in the room. See if the leaves are yellow. Cut off what should be cut off and sprinkle water, because it is her habit to keep moving. Sometimes you just check here? Evergreen tree? Sometimes I say Mr. Lu Xun, right in front of his photo, but that feeling is as long as talking about the ancients. As for the vase? Standing on the grass of the cemetery, and the bottom of the bottle has been lost. Although it has been lost, it will remain standing by the grave. What I see is standing from spring to autumn; It stood until the pomegranate in the nearby grave bloomed and turned into pomegranate. Only Mr. Xu has been here once since the fire, and no one else has been there. Of course, the grass in the tomb is very high and barren. Where is the vase? I'm afraid Mr. Lu Xun's porcelain bust will be buried in his chest by weeds. We can only write articles in memory of Mr. Lu Xun here, but who will try to cut the weeds on the tomb? We are getting farther and farther away, but no matter how far away, weeds always remember.
