Flying spiders watched spiders weave webs, and I remembered what and what?

Birds and butterflies come to mind, because birds and butterflies can fly.

Birds. Birds are usually feathered, oviparous animals with extremely high metabolic rates, and their long bones are mostly hollow, so most birds can fly. Birds evolved from reptiles, and there are more than 9,000 species of birds in the world, all of which have wings and feathers, even those that have lost the ability to fly (such as ostriches, penguins, etc.).

The first birds appeared 100 million years ago.

The body is spindle-shaped, the forelimbs are specialized into wings, the body surface has feathers, the body temperature is constant, the musculothoracic is developed, the bones are healed, thin, hollow, and the brain is relatively developed. Having an air bag allows for double breathing, and not having a bladder can reduce body mass. These physical traits are well adapted to flying.

Birds have no teeth but have beaks that can be used for hunting, nesting, and grooming feathers. Birds are good at building nests, and they can build all kinds of nests from the various materials they collect. Ornithischia is taxonomically a class under the subphylum Vertebrates.

Feather. Birds are the only animals on earth that have feathers. The vast majority of a bird's body surface is covered with feathers, which not only keep the bird at a constant body temperature, but also allow it to fly. Birds have different shapes of feathers.

Structure. The ** of a feather has a hard shaft, called the feather shaft, the upper feather part is called the feather trunk, and the lower part inserted ** is called the feather root. The feather trunk is flanked by feathers, which are made up of a tough substance called keratin, which in turn is made up of feather branches and feathered twigs.

Grow. Feathers are formed from the follicular vesicles of the feathers on birds**, and the parts are grouped together in a special way. Most birds moult at least once a year, when new feathers grow and old feathers fall off. Birds renew their already damaged feathers through moulting.

Freshman. Birds usually moult twice a year, which shows that feathers have a strong ability to regenerate. Scientific studies have shown that feather stem cells are distributed in a ring on the wall of the feather follicular vesicle, which can proliferate and differentiate, and the differentiated cells grow upwards to produce feathers.

The proliferation and differentiation of feather stem cells allows the entire feather organ of birds to grow and regenerate.

Type. Bird feathers can be broadly divided into four types: body feathers, down feathers, tail feathers, and wing feathers.

The body feathers cover the whole body, forming a smooth, streamlined body surface of birds; The down is fluffy, so that the warm air will not dissipate quickly; The tail feathers and wing feathers are more powerful and are used for flight.

A: When I watched spiders weave webs, I thought of butterflies and birds.

It's not as simple as the spider thinks. I said to the spider: you must persevere in everything you do, and don't be intimidated by a little difficulty, otherwise you will achieve nothing.

The author of this text is Lu Bing.

The text is a fairy tale, about the spider because of loneliness, boredom and thought of the way to open a store, originally textile is its specialty, it can play its strengths in opening a textile store, but it is afraid of difficulties and chose to escape, therefore, it opened three stores, and finally ended in failure.

Habits. Spiders feed on insects, other spiders, myriapods, and some spiders also feed on small animals. Jumping spiders have good eyesight and can dive within 30 centimeters to catch their prey and pounce on them. Crab spiders wait for their prey on flowers that are similar to their body color.

Spiders burrowing in the earth build burrows lined with silk, and the entrance of the burrow has a trap that opens at night to prey on insects that pass through the hole. funnel spiders weave funnel webs, and insects fall into the nets to cause vibration; The spider itself resides in a filament tube with a narrow end that leads into a plant or a crevice in a rock.

The spider finds a foothold from a tree, and draws out many filaments long enough to reach the opposite side, so that these filaments float in the wind, and then it touches the anchorage point of the spider's silk with its feet at all times.

If any of the threads can't be pulled, then the threads are already wrapped around the trees opposite, and the "heavenly rope" is erected. Like the pillars of a house, it sticks a few more strands back and forth on this supporting line that is bound to be a spider's web, making it into a thick "cable". Then, under this thick "cable", a second "cable" was erected in parallel.

The spider crawled around, and the web was erected on these two "cables".

It is to first pull a very long, long silk thread, then a pair of dimes, and then pull another one, and then pull the net around this cross-shaped line, and this is how it is done slowly.

It draws out many filaments long enough to reach the opposite side, and the filaments drift in the wind, and then it touches the anchorage of the spider silk with its feet at all times.

Original text of "The Flying Spider".

One evening, I noticed that a black spider had formed a large web between the two eaves in the backyard.

Can spiders fly?Or, from this eaves to that eaves, the middle is more than one zhang wide, how did the first line pull through?

With this question, I tore up all the cobwebs in the yard.

Later, after careful observation, I found that it had taken many detours - starting from a cornice, tying a knot, going down the wall, crawling forward step by step, carefully winging, cocking the tail, not letting the silk fall on the sand or other objects on the ground, walking through the clearing, climbing up the opposite eaves, the height was about the same, or it was satisfied, and then tightened the silk.

It takes more than half an hour to collect the first strand until it becomes a straight line. The subsequent process is generally much faster than the placement of the first thread. Despite its complexity, the spider is very skilled at it, and it seems to be a pleasant and entertaining performance.

The spider is not supposed to fly, but it can hold its web in mid-air, and it is a hardworking, sensitive, silent and stoic little creature. Its web was delicately woven and regular, and it was spread out in the shape of a gossip, as if it had been helped by God.

Such achievements make people think of those who are silent and some wise men who are deeply hidden.

So, I remembered:

The spider can't fly, but it still holds its web in the air.

Miracles are created by perseverance.

Why is the flight in the title in quotation marks.

You can feel the laid-back and pleasantness of the spider.

From the second grade Chinese book "Thunderstorm", the original sentence is: The rain has stopped. The sun is out.

A rainbow hangs in the sky. The cicadas chirped, and the spiders sat on the web again. The pond was full of water, and the frogs were croaking.

Through anthropomorphic techniques, the laid-back and pleasant nature of spiders is highlighted.

The sky was full of dark clouds, and it was dark and heavy. The leaves on the trees are motionless, and the cicadas do not make a sound. The word "pressure" in this sentence can feel that the dark clouds are coming very fiercely.

The spider hung down from the web and fled. From the word "hanging" in this sentence, you can feel that the wind is very strong, and the spider is also very afraid.

Original sentence: The little spider quickly crawled into the house and weaved a large and beautiful web on the eaves.

Abbreviation: Spider weaves webs.

Analysis: Everything else is a definite sentence, and the abbreviated sentence only needs the subject predicate object to the dust language.

One day, when I was drying clothes on the balcony, I saw a spider weaving a web, and I was not happy, so I used a hanger to stab its web and used a bamboo pole to break it.

At first, I thought the spider had run away, but instead of giving up, it turned back. I hit it with a bamboo pole, and I hit it to the left and the right to the right, and it dodged left and right, but I still broke one of its legs. But the spider persevered, slowly crawling up the web.

This time, I was so angry that I simply sprayed it with water. It was washed to the ground by the water and struggled in the water. I watched it struggle and laughed sinisterly, too lazy to bother with it anymore.

It limped again and "crawled" onto the net. Its feet were glued to become a two-legged spider. Yet, in spite of this, it continued to weave the web. When it weaves a net, it has to do everything possible to keep itself from falling, which is really hard.

When I was about to use my most ruthless trick, the insecticide, it stared at me with its helpless, sympathetic eyes, and then my heart relented, and everyone has the right to live! Even if it's a young acorn and a small life! Liang Zao: I am extremely ashamed of my behavior.

I was really impressed by the spider's tenacious vitality and perseverance. I thought: if we have a spirit like a spider weaving a web, then what else can't be done? As long as you persevere, you can win.

That's what spiders weave webs to me.

The spider sat on the web again, and from the word "sit" in the sentence, we can feel the leisurely and pleasant nature of the spider.

Extended Material: Thunderstorms is a chronological description of the scene. Example sentences that express the actions of animals through anthropomorphic techniques: The bird is standing on the tree and singing again. The swan crouched on the beach again to rest. The little rabbit picked up the radish again and nibbled on it.

Thunderstorms, also known as thundershowers, are violent weather phenomena produced by extremely unstable conditions of air, often carrying strong winds, heavy rain, lightning, lightning strikes, and even hail or tornadoes, so they can often cause disasters. There is also Cao Yu's eponymous Yanpiqing drama "Thunderstorm".
