Listen, what's this noise? The hissing spider is weaving a web!

He was knitting when a strong wind blew, the trunk was shaking and the leaves were flying all over the sky. At this time, the spider could not escape to a safe place. He clung to a silk and struggled in the wind. The wind stopped, he didn't give up, and began to weave again. It was really unexpected. It seemed that the weather was bad for spiders, and soon it was dark again. Then there was a thunder, and the bean-sized raindrops fell from the sky, turning the leaves and cobwebs into "wolf skins." I don't know why the leaves jumped into the ground and the cobwebs were weak and smashed into powder. The rain stopped. I guess spiders might give up! But the fact tells me that he has been weaving the net tirelessly until it is completely woven. At this moment, the sun came out and made his face red. ...

In life, there are many such "spiders", such as Hawking, who made up his mind to study physics and astronomy at the age of thirteen or fourteen. At the age of seventeen, he won a natural science scholarship, and he successfully entered Oxford University. Soon he found that his muscles began to atrophy, and then his whole body was almost paralyzed. The electric wheelchair replaced his feet. He not only relies on computers and language synthesizers to help him speak and write, but also asks others to spread out every page on the table and let him read page by page. Faced with all these difficulties, he did not bow his head, but overcame the disease with indomitable will and made great contributions to cosmology. As one of the most outstanding scientists today, he proved that disability is not an obstacle to success. His love for life and enthusiasm for scientific research deeply infected me.

People like Hawking are Helen Keller, an American blind and deaf woman writer. She suffered from blindness and deafness when she was one and a half years old, but she didn't give in to fate and overcame the disease. At the age of 24, she graduated with honors from Radcliffe Women's College of Harvard University. With amazing perseverance and tenacious spirit, she completed the road of life, made contributions to mankind and became a respected person.

There are many such people. Pu Songling, the author of Strange Tales from a Lonely Studio, went to the exam several times and fell into Sun Shan. He said, "Where there is a will, there is a way, cross the rubicon, and one hundred and twenty Qin Tian will eventually lead to Chu; Hard-working people are paid every day and diligent, and more than 3,000 armor can swallow Wu. " Self-encouragement, I wrote this masterpiece and became a monument to classical literature.

I remember Wang Anshi's Plum Blossom wrote: "There are several plums in one corner, and hanling blooms alone." The plum blossom in the corner of the poem blooms in the cold, and the spirit of fighting frost and snow is not the brave spirit of spiders.

The plum blossoms that are proud of snow and the spiders that persist in the wind and rain are all "friends" worthy of my life.

Comments:

This article is an argumentative paper. The author thinks that Hawking, Helen Keller, Pu Songling and others have finally succeeded through unremitting efforts from observing spiders' unremitting web weaving. The value of this article lies in that the young author did not confine his eyes to the spider itself, but extended it and quoted several convincing examples, which made the article richer and more exciting.

Ⅱ 600-word composition on spiders (People's Education Edition)

When it comes to spiders, an ugly image will probably come to everyone's mind: eight curved and segmented legs, a spherical abdomen, and a pair of jaws with more or less toxins ... This image often makes people who don't know much about spiders think it is a pest. However, is this the case?

I have observed spiders for a while and found that most spiders are not pests, but they are very beneficial to human beings! They caught a large number of pests in their own unique way. As far as I know, there are two ways to catch insects: the first is the "waiting for the rabbit" method. It first weaves a gossip-shaped sticky net with silk in its belly, and then hides in a corner that is not easy to be found, waiting for the arrival of flying insects. If some unlucky flying insect hits the net, its body will get stuck and can't move. At this time, the spider will quickly climb over, bite the prey and inject "anesthetic" into its body to turn the internal organs of the prey into liquid. And finally? Dinner, of course! I have only seen the second method of catching insects once, and I don't know much about it. This method of catching insects is relatively simple, and there are not many prey caught: it will pounce on its prey like a beast. At the speed of spiders, it is ok to catch some reptiles that can't fly, but what about those flying insects? Will greatly reduce the discount!

In addition, spiders are also excellent meteorologists. On a sunny day, it lazily basks in a large horizontal net. Of course, if it can stick to an insect, it will be an unexpected gain for spiders. On rainy days, spiders will leave the horizontal web and weave a vertical web in another shelter. When you come back after the rain clears, you will find that the horizontal net has been smashed by raindrops, but the vertical net is intact. According to this phenomenon, we can know that it will be a sunny day when spiders make horizontal webs; When spiders spin vertical webs, it will rain.

After this introduction, you should know something about spiders! In fact, my observation is only one-sided, and spiders also have pests. Do you want to know? Please use your head and observe more. If anyone knows more about spiders, please communicate with me to enrich our knowledge.

Hope to adopt.

ⅲ asked to write a 500-word composition about spiders, and it must be 500 words.

I caught a spider alive and kicking. Its front is dark brown with many stripes and spots. It has four round eyes. Eight legs, a closer look, there are many hairs much thinner than needles. From a distance, it looks like a little black flower. Its back is reddish brown, and you can see its forked teeth.

I put him in an inverted disposable cups, and then I ran the treadmill.

On the treadmill, I suddenly found a black and yellow bug. I grabbed him and put him in the cup next to the spider's cup, observing their every move. I saw the spider run where the worm saw it. It seems that I want to eat worms. The way it doesn't eat "lunch" has to make people laugh.

I saw that he was all thumbs, so I had to lock him up with bugs.

After a while, I saw the spider, which was still in hot pursuit at first, stopped on the cup and stood there quietly, motionless. I looked at the back of it, and small drops of water like glue appeared in front of my eyes. Hey, how did the little water drop get longer? Turned into spider silk. The sun shone on the balcony, and I found that the "tight encirclement" laid by the spider was impenetrable!

After a while, when I was thinking sadly, I heard a "buzzing" sound. On the balcony, the bug is struggling desperately, but how can the spider wait for it to break free? The spider suddenly passed by, and in the blink of an eye it was next to the bug, which was still struggling. Slowly, slowly, the bug stopped moving, and the spider flew over and ate it.

Spiders are really good at catching insects!

Ⅳ Why do spiders know about things on the Internet? 600 words.

People who see cobwebs may think that spiders must weave warp threads one by one because of their complete structure, but they are not. Spider weaving is to pull a few warp threads first, then run to the other end and repeat the same action. The way spiders weave webs makes sense. Because if it weaves the warp in sequence, it may not be able to take into account the overall situation, and it is easy to bias the net to one side, but pulling the warp at both ends evenly can make the net tighter and more evenly distributed. Because spiders run around when they spin webs, many people think that their webs will be biased to the other side. When the work was finished, people found that the original spider web was such a uniform and symmetrical work of art that they could not help but gasp in admiration. If we compare the distance between the meridians, we will find that they are all kept within a certain range, which is thinner and denser for a while, just like measuring with a square. Why can spiders keep the regular structure of their webs in the seemingly random weaving process? First of all, different kinds of spiders use different numbers of warp threads when weaving webs. I counted them carefully: 2 1 Onigumo, 32 golden spiders and 42 red spiders. When all the warp yarns are woven, the spider will return to the shaft to rest, and then engage in weft knitting along the shaft pulled by the warp yarns. The spider's axis is the midpoint, and it slowly weaves a horizontal line around the warp with filaments that are almost invisible to the naked eye. The interval between each horizontal line is very precise. I call this carefully woven area the "rest area". After the rest area was built, spiders began to pull thick silk, which can be seen. It can adjust the thickness of silk thread at will, and use spiral weaving to open the space between thick weft yarns, even the space between weft yarns woven by little spiders is 2. 5 centimeters. The above is part of a spider web. (Because it's really difficult to record the whole process of web weaving ~)

Fourth, the composition of spiders

My balcony is a "small garden". Although small, it is very colorful. There are not only flowers and plants here, but also insects and birds, which add a lot of color to the garden and make the whole garden full of vitality.

Hot summer is the peak of insect growth. One day, I found a spider on the flower branch. This spider is no different from other spiders. Its gray-black body is heavy and ugly. But its eight feet are very flexible in weaving webs on the branches of flowers. It's very fast. It uses its right hind foot to cooperate with silk, and the other foot is used for crawling. When it climbs to the corresponding position, it sticks it to the net with its right hind foot, and then climbs again ... So it turns round and round, and it doesn't take long to weave a net, which is very neat and symmetrical.

The web was shaking in the wind, and the spider climbed to the center of the web, as if waiting for something to come … I walked away.

A few days later, I found some balls on the internet, and something seemed to be crawling inside. I went to ask my father, and he told me that it was a spider egg, and there were so many little spiders in it. Once we were born, our balcony would be covered with cobwebs. So my father asked me to take down these nets, and I must destroy them. The "heavy responsibility" was given to me, and I took action at once.

I immediately found the tool:-a bamboo stick. When I wrapped the whole spider web around the bamboo stick, it happened that the egg broke and the little spiders squeezed out one by one. In desperation, I put bamboo sticks in the bucket next to me, and I wanted to drown them. They kept jumping up, and I kept stirring bamboo sticks in the water and drowning them, leaving none.

Okur Mo Ye kept struggling, pushing the spider, as if telling her children: Climb up, climb up ... They won't give up, and I won't give up. I have been hiding them, and my mouth has been shouting: drown you, drown you ... some little spiders climbed out of the bucket and quickly fled to the flowerpot; Those who didn't climb out were still climbing hard on the barrel wall, climbing hard ... My movements gradually slowed down and I looked at the scene before me. Finally, I stopped moving.

Okumo in the bucket is dead. I killed it. I gave up. I took the bamboo stick out of the bucket and put it on the ground, so that the remaining little spiders could climb back into the flowers. I gave the spider a chance to live The little spiders outside the bucket are running away and crawling in panic ... I let them go because of their belief in survival and their right to life.

ⅵ Composition: My Story with Spider

[Spider Story] Spider is a very weak animal, but it has existed since ancient times. Why does it still exist? Next, I will tell you a fairy tale about spiders.

Once upon a time, a spider found a big tree with lush foliage in the forest. It slowly climbed up the tree trunk. When it found two branches suitable for weaving a web, it began to spin silk. While vomiting, I retreated from the upper branch to the lower branch. Silver-white filaments gently swaying in the breeze, very beautiful. At this time, a little squirrel ran over and said, look, it took so long to spit out two filaments. How difficult it is!

At this moment, the wind came. It seems to be attacking spiders on purpose. With a whimper, it blew off two filaments that the spider had just spit out. The spider fell down at once, but fortunately it was stuck by the newly spit filaments and hung in mid-air. It paddles eight thin legs and climbs up along the filaments. The little squirrel was so scared that he hid in a tree hole and said, look, how dangerous it is. I must rely on my own efforts to build a beautiful home.

The spider's words were heard by the wind, and the wind was very moved and left quietly.

The wind stopped and the spider began to spin silk again. It is so earnest, so careful, so patient. Time passed little by little, and it got dark. The filaments form a beautiful net, and each grid of the net is so symmetrical. Looking at the home that will be built soon, the spider's heart is full of joy.

Who knows, at this time, the rain came again, and I wrote the composition "The Story of the Spider" in the fourth grade of primary school. Huge and dense raindrops broke the spider's rapidly woven web. The broken silk screen hangs on the branches and swings. The spider is not afraid, but grasps the broken filaments tightly to avoid being hit by raindrops.

Rain sees spiders so tenacious that they can't bear to be destroyed again. It stopped raining and left quietly.

The rain stopped and the little squirrel climbed out of the tree hole. He looked at the tattered screen and said regretfully, you see, you didn't listen to advice and suffered a big loss. Give it up! The spider didn't answer, and silently began to spin again, because it just wanted to weave the web quickly, so that it would have a beautiful home.

Grandpa Sun gradually climbed up from the other side of the mountain, and it was dawn. The spider's home is finally finished, and colorful sunshine shines on it, which really looks like a beautiful silk painting. The little squirrel looked at the golden silk screen in the sun in surprise and said enviously, I really admire you! You are so tenacious, so not afraid of setbacks, so persistent.

The spider listened and smiled happily.

ⅶ 600 words of inspirational composition given by spiders.

Spider inspiration

There is such a book, there is not a word in it, but there is learning everywhere. The name of this book is Life. Every page of it is knowledge, and everything is revelation.

One day, I saw an unfinished net at the window. There is a spider on the internet. Spiders kept crawling, trying to weave a complete web with silk. But when it was busy and almost finished weaving, a strong wind blew it away, and so did its net. The spider struggled to climb back into its broken net. I can't help but feel sorry for it: the hard-worked net was destroyed like this. But it just turned around and began to knit again. I think the spider must be very angry now, but she can't help it. He repeated the same action, and this time, after a long time, he knitted another net. Suddenly, someone poured some water upstairs and washed away its net. I think, after this, the spider may get angry. But the spider doesn't seem to be angry at all, and weaves quickly again. I am very curious, staring at it closely, thinking: is it angry, or is it competing with fate? But how can it overcome its own destiny?

After about four or five minutes, it weaves the web again. Suddenly a drop of water fell on my head. It will rain. Spiders seem to realize something, like ants on hot bricks, in a rash. It seems that it suddenly becomes smart, only to see it swallow the woven net into its stomach and change its direction to weave the net vertically, so that the rain will not rain on the net. Finally, the storm came and its web was finally woven. No amount of rain can hurt it now. It sits safely on the internet, and I am glad for it.

The rain stopped, the sun came out, the golden light shone a rainbow, and my mood was as gorgeous as this rainbow! Because the spider successfully overcame the difficulties and woven a complete web.

I feel suddenly enlightened, thinking that as long as I have perseverance, perseverance and perseverance, I can overcome any difficulties like a spider.

ⅷ composition fairy tale "Moon Palace"

Little ants envy spiders very much. It often thinks, if only I could spin silk like a spider. I can weave a net and wait, but I need to do heavy work every day.

One day, it was going to rain, and the ants left their original home. They parted, built a new house and slept. In the middle of the night, the little ant suddenly woke up. It saw a spider lying on the internet not far away. The little ant got up and sneaked out of the door.

"Hello, Brother Spider!" The ants greeted each other warmly.

"Who bothers me in the middle of the night?" The spider turned over impatiently. "Oh, it's a little ant. What are you doing here without sleeping? "

"It's almost dawn. I will come to play with you. " The little ant said shyly.

"Well, let's talk!" The spider said happily.

"I envy you very much!" The little ant said sincerely, "Can you teach me to spin silk?"

"Can you spin silk?" The spider said in surprise, "You don't have spinning tools!" " Besides, you can look for food everywhere, so why wait like me! "

"How wonderful your life is! With the internet, you can have food when you wake up. As for me, I have to look back and forth every day, and my legs are going to break! "

"You don't know my pain!" The spider sighed, "My web has a shelf life. After a few days, it couldn't stick to food, so I had to eat it and knit a new one. " I'm really awake, and I have to work in the middle of the night. Dark circles scared me to death! How I envy you ants, how nice it is to work during the day and sleep at night! "

"Oh!" Little ant nodded thoughtfully. At this time, he heard his mother calling him, and quickly said to the spider, "We all have our own difficulties. Don't envy me!" " "Then I went home.

A good life comes from labor, and no one can sit back and relax. The little ant said silently in his heart.

Little ants envy spiders very much. It often thinks, if only I could spin silk like a spider. I can weave a net and wait, but I need to do heavy work every day.

A good life comes from labor, and no one can sit back and relax. The little ant said silently in his heart.

ⅸ Spider Spider What touched my heart?

I waved my hand on the spider web, and the spider was frightened and got into a small hole behind me. In order to draw it out, I caught an ant and threw it on the spider web. Unexpectedly, because I pushed too hard, the ant died and the spider wouldn't come out without causing vibration. I didn't lose heart. I caught another ant and spit it out. The ant was badly hurt. Although he survived, he had no strength, but only caused some slight vibration, which did not attract the attention of the spider. I gently caught an ant and put it on a spider web. This time, the spider crawled out slowly, plunged into its two fangs and took it back to the hole.

Now, let me tell you the origin of the spider's name. If you open Li Shizhen's Compendium of Materia Medica, you can see that it says, "If you set a net for this thing, you will be punished if you touch it. Zhihu's unjust people took their spiders. "This is the origin of the spider name.

Network can be described as a spider's representative, including horizontal network, vertical network and funnel-shaped network. .....................................................................................................................................................

My favorite spider web is the one that is stretched from top to bottom. Once the prey enters its "net array", there is almost no chance of escape. As long as you accidentally touch a line, the spider on it will know that the prey is coming and come down to hunt down. Spider webs can also predict the weather! On sunny days, it will weave horizontal nets, but once it feels that it is going to rain, it will start to weave vertical nets to avoid being homeless after the rain.

Some spiders are strange. The largest spider in the world is in the tropical rain forest. There is a kind of spider that can catch birds! Of course, the smallest spider in the world is the display spider. Someone once caught an adult male display spider in the West Samoan Islands, and its body length was only 0. 043 cm, really amazing!

Every time the early rice is cut, the spiders in the field begin to decrease. But when people planted late rice, the spider family flourished again and began to catch pests.

The composition of ten spiders

Stepping into the gate of Spider House, there is a giant "spider" ready to move! Because a sensor is installed on the ceiling of the entrance to the Spider Pavilion, whenever someone enters, the robot spider hanging high in the center of the pavilion will start, just waiting to "run away" to scare you when you visit.

Speaking of it, spiders are well-known "wrists", and some places are more magical than humans! According to scientists' estimation, the spider "family" has lived on the earth for at least 380 million years and has evolved into 105 families and170,000 species. If the members of the spider "family" can be evenly distributed all over the world, there must be spiders within every 1 square meter. According to the survey, the rice fields in the south of China are the "downtown areas" of the spider world, with more than 3 15 heads per square meter. In northern China, there is also a folk proverb: "If you don't clean the house for three days, there will be cobwebs."

So what do we know about spiders? Of the 6.5438+0.7 million species of spiders, only 34,000 are known to human beings. Look, the reporter made a joke as soon as he opened his mouth: "Spider is a very special kind of insect." The commentator immediately corrected: "Wrong, spiders are not insects. Although they all belong to the phylum Arthropoda, spiders belong to the class Arachnoidea rather than Insecta. Spider's body is only divided into two parts: head and abdomen, with eight legs; This insect's body is divided into three parts: head, chest and abdomen, and it has six legs. The friendship between spiders and insects is not only profound, but also "enemies". Spiders can devour 80% of insects. When it comes to kinship, scorpions are close relatives of spiders.

If you haven't dated the spider family, you don't know the following-the spider family has the ability to challenge all kinds of extreme living environments on land, such as branches, forests, flowers, mountains, caves, coastal areas and even deserts, and some spiders even live in fresh water. The smallest spider in the world lives in the deciduous layer, with a body length of only 1 mm, which can only be really seen under a microscope. The biggest spider in the world is Grice, a bird spider. Grace is a giant in biblical stories. He lives in the tropical rain forest of Latin America. His length is 65,438+00 cm, his weight is 65,438+035 g, and his limbs can stretch up to 25 cm. Frogs, lizards and even small mammals can be reduced to its food.

◆ Special note: The exhibition area of Spider Pavilion is about140m2, which is divided into five exhibition areas: spider overview, spider experience, mating and reproduction, web weaving and spider venom, and 28 families 105 families of spiders are displayed. There are specimens, models and living spiders in the museum for viewing, and there are graphic display boards, video films and voice interpreters to explain the relevant knowledge to you.

Feel the spider

Might as well accept the invitation of the spider family to see the world, listen to the world and perceive the world from the standpoint of spiders-

Spiders with special senses have eight eyes, which are reasonably distributed around their heads. Although most spiders can't move their eyes and focus accurately, they can look around, and they also have a special skill: "detecting" polarized light in sunlight. So the spider sees a twisted but infinite world, and can position itself according to the change of the position of the sun.

The nature of bisexual spiders is that they would rather hide than fight, and they will never bite unless they have to, but sometimes they can become their biggest natural enemies-there is a spider with long fangs that specializes in eating spider eggs or young spiders, not to mention adult spiders and spouses nearby. The growth of a spider is a very painful thing, because it has to go through a life-and-death molting process. The spider family's life is so full of contradictions that it can only be explained by "dual personality"-both fragile and brave.

Spider love Some kinds of male spiders are overbearing. After mating, they will break some tentacles or secrete some substances to block the seminal vesicle of female spiders to ensure that no other male spiders can follow in their footsteps. In contrast, the female spider's love is much more selfless. They firmly protect their babies with egg bags. For example, in the first three weeks, wherever she went, the wandering spider's mother put the egg bag in her mouth, and she didn't eat or drink. The little spider died soon after hatching.

Spiders have been spinning silk all their lives. In addition to cobweb traps, the "finished products" of spider silk also include tablecloths, beds, cradles, telephone lines and safety belts. Frame wires and warps can support spider webs, bonding wires release "super glue", binding wires are used to bind and reinforce prey, dragging wires can make spiders jump even higher, and multi-purpose wires can attract prey, cover themselves, warn intruders and weave sleeping bags. In terms of comprehensive performance per unit area, there is no rayon in the world that can compare with spider silk. If there is Spider-Man, his weapon really only needs to be as thick as spider silk.

◆ Special note: There are many interactive games in Spider House. Jigsaw puzzles, guessing prey, identifying spider silk and weaving spider webs can help you understand the world and life of spiders.

Inspiration from Spider Exhibition

Everyone who has participated in the preparation of the Spider Pavilion feels "benefited a lot", not only because of the Spider Pavilion itself, but also because of the knowledge and enlightenment it brings. In order to prepare for the Spider Museum, the staff of Shanghai Science and Technology Museum searched for experts all over the country and only found a real spider scientist. From the perspective of bionics, the research value of spiders is extremely high. In contrast, although western countries have always been afraid of spiders, they know much more about spiders than we do. According to Qian, deputy secretary of the Party Committee of Shanghai Science and Technology Museum, many things told by the Spider Museum are the research results of the Smithsonian Institution of the United States.

What's more commendable is that there is an invisible bridge between the research institute and the museum: not only researchers focus on scientific research and publish papers, but also some people show their scientific research results to everyone in time. We should also consider avoiding rigid preaching and guiding visitors to see, listen and feel in plain language; At the same time, there must be social philanthropists like Mr. Beling, an American who sponsored the exhibition, who are willing to invest in popular science. Qian said, I believe that the Spider Museum will open up the idea of running a science and technology museum, and will also introduce more Mr. Behring into the science and technology museum. This is the greatest wealth!
