What is the selfless devotion of the cicada? Cicadas are delicious, what is it worth?

Although cicadas are not pests, their dedication to nature and human beings can be said to be equal to pollution.

Dedication (only two and a half o'clock):

1. The medicinal value of cicadas: cicadas are called cicada molts their skin, which is rich in chitin, isoxanthin, red butterfly, adenosine triphosphatase, and is often used for external wind and heat, cough and hoarseness. Sore throat.

Rubella itching, red eyes, tetanus, pediatric epilepsy, night crying and other symptoms, according to the "Chinese Materia Medica" record, but also beneficial to the essence of the yang, thirst quenching, lung and kidney, antibacterial and antihypertensive, baldness and disease treatment and other effects.

2. The nutritional value of cicadas: cicadas have cold throats, fragrant tastes, and have the functions of dispersing wind and promoting lungs, relieving fever and calming shocks. Cicada monkeys are nutritious and have a mouthy taste, making them a fashionable delicacy.

The cicada body is rich in nutrients, with a dry protein content of more than 70, a fat of about 7, vitamins and various beneficial trace elements are higher than that of general meat foods, and it can be called the king of protein in today's food.

3. Provide children with childhood fun, digging cicadas, catching cicadas, and fighting cicadas are not dangerous, children can pass the time, and parents can rest assured.

Harms: 1. Destruction of vegetation: cicada eggs are often laid in woody tissues, and nymphs burrow into the ground as soon as they hatch and suck the sap from the roots of perennial plants.

Too many nymphs will cause trees to wither and die due to lack of nutrients, so those hundred-year-old trees and ancient trees will be protected and killed every year, in fact, to prevent cicadas from harming trees; Adult cicadas also have to absorb nutrients from trees, and when there are too many cicadas, trees suffer.

2. Although the chirping of the cicada has not yet been defined as noise, and many literati and writers still define it as the sound of nature, in the increasingly developing era, the chirping of the cicada has deeply affected our normal life. The silent factories of industrial production (electronics, silk screen printing, instruments) need to be silent, and they know it; In the hospital, the mood of the people was annoying, and they called when they knew it. I guess you don't always think that the voice of Zhizhi is beautiful

3. The excessive reproduction of cicadas will lead to soil relaxation and soil erosion.

In fact, the cicada has one of the greatest spirits, and it is also its true selfless dedication: perseverance, never give up, just to see the sunshine!

After the cicada eggs hatch into nymphs, they immediately burrow into the soil, less than two or three years, more than ten years in the ground after all, they do not see the light of day, they generally have to go through five metamorphosis, only the fourth metamorphosis into adults can really see the sun, they are a kind of insects that want to see the sun but can not see the light, after the fifth metamorphosis, a few months (up to four months) will return to the west. Its spirit can educate future generations, and it will not give up. Although the ending is very regrettable, a bit sad of "missing a thousand years, just in exchange for a smile from you", that kind of spirit is also worthy of our admiration.

No. Cicadas: Medium- to large-sized insects of the family Homoptera, about 1,500 species.

It is 2 5 cm (in) long, with two pairs of membranous wings, compound eyes prominent, and three single eyes. There are two species in the family of Mantises, commonly known as hairy cicadas, which are found only in southern Australia, including Tasmania. The male cicada has a tympanic membrane at the base of its abdomen, which makes a loud sound when it vibrates the membrane.

Most cicadas make rhythmic ticking or whining sounds, but some species are very vocal. The eggs are often laid in woody tissues, and the nymphs burrow into the ground as soon as they hatch and feed on the sap from the perennial roots. Generally, it takes several years to mature after 5 molts.

Cicadas are not considered pests, but when there are many females, the oviposition can damage the saplings.

So it's not good.

If it's silkworms, that's another story.

Singing in the trees every day makes it difficult for me to sleep in the afternoon.

Yes Maybe it's the opposite textbook.

In fact, in my opinion, everything in the world is the same selfless dedication, because they are all living for their respective missions, just in the process of survival in order to eat well, so there seems to be selfish behavior, but let's see if the silkworm is not normal if it does not spin silk, that is its entire physiological process, just to educate people and describe. The question of substance does not mean that it is selfless, but rather that it must go through a process of eating its own food in nature and then beginning to excrete at a certain time. If we talk about the superficial problem, then there are too many similarities in nature, such as food and the like, all of which are eaten by people, and there are more animals, which should be considered dedication.

Teachers are gardeners, doctors are angels, cleaners, and soldiers guarding the frontiers, and I think so are the vast masses of the poor, although they are all in their ordinary positions, they are selfless people, they do not live for themselves, they live for the betterment of others, for the better of the great motherland.

Teachers, doctors, and other service workers.

It belongs to the high-protein insects.

We Shandong people like to eat is not the Zen that has climbed out, but like to eat the cicadas that have not climbed out of the soil, we call it the monkey, that is delicious, wash and soak in salt water and fry it is delicious!

The cicadas are uncomfortable when I see them, they are black and not garbage, and they have wings... Don't tell me you haven't seen cicadas before they shed their shells?

In the famous French entomologist Fabre's "Insects", there is such a description of cicadas: "The underground life of the cicada that has not grown up is still an undiscovered secret, all we know is that before it grows and climbs to the ground, the underground life has gone through a lot of time, and its underground life is about four years." After that, the singing in the sun was less than five weeks.

Four years of dark hard labor, pleasure in the daylight of January, this is the life of the cicada. Because it has been digging for four years, it is now suddenly dressed in beautiful clothes, and has wings that rival those of a bird, and is bathed in the warm sunlight. The sound of the cymbal could be high enough to sing the praises of its joy, so rare and yet so fleeting.

I think the spirit of the cicada is: years of forbearance, once born, it will be a blockbuster.

The change in the author's feelings towards cicadas in the article is: (annoyance) The key reason for the change from inhibition to promotion is the profound truth about life triggered by cicadas. Whether it is writing about the annoying noise of cicadas, the weakness of sick cicadas, or writing about the short life of cicadas buried under the mud for 17 years and only living for one summer, it is because of this sentence that it seems to have factory meaning and brilliance.

It also reminds us to live well, no matter how short life is, and to give people a feeling of upliftment. ）

The author writes about cicadas, first suppressing and then promoting.

Suppression: The noise of writing cicadas annoys people, which is a depression. Secondly, write about seeing a sick cicada, write about its tininess and weakness, and a depression.

YJ: The life history of the cicada shows the meaning of life.

"Got it—got it—" There was a cicada on the banyan tree by the pond that was chirping happily, and behind the cicada there was a praying mantis holding leaves to cover itself and waiting for the opportunity to poison it, and after a while, the praying mantis finished eating the cicada, and a yellow finch moved slowly against the branches, silently, the yellow finch suddenly snorted and caught the mantis, and then the person who had been standing there under the tree quietly took out a slingshot, loaded the stone, and aimed at the yellow finch. After a while, I took it home and drank it.

This is the story of "the praying mantis catches the cicada, and the yellow finch is behind". Although this story is widely circulated, people's discussions are all about the short-sightedness of the praying mantis and the carelessness of the yellow finch, especially the mantis's short-sightedness that only cares about the immediate interests and does not care about the future troubles. But who has ever heard the cicada's wail?

The cicadas are just daily meals, drinking dew, entertaining themselves, chirping happily, harmless and unguarded. But unlike the praying mantis and the yellow finch, in order to achieve their own personal goals, they use that insidious means to frame others, but they don't know that they have become someone else's meal. In comparison, I would rather be innocent than a sinister and vicious criminal.

Some people may say that the inspiration of this story to people is not to blindly entertain themselves like cicadas, not to learn from praying mantis short-sightedness, and not to learn from the paralyzing carelessness of yellow sparrows. In fact, it is not, use logic to reason: cicadas are the origin of all substances, how can no cicadas attract praying mantises, and how can they feed the yellow finch without praying mantis?

Then use biological analysis: the law of the jungle. Praying mantis eats cicadas, yellow finches eat praying mantises, people eat yellow finches, if there is no selfless dedication of cicadas, then what is left?

The cicada is optimistic and cheerful, although its life is extremely short, although its daily life is uncertain, although it is often devoured, and it keeps a happy mood to sing and hiss every day. Its material life is hard, but its spiritual life is fulfilling. At this point, we who are comfortable and comfortable every day, is there something worth learning from the cicada?

I want to be a cicada ......

It is difficult to say goodbye when we meet, and the east wind is powerless.

The spring silkworm is dead to the end, and the wax torch turns to ash and tears begin to dry.
