The wild boar came to describe the composition in 600 words.

1. Can you shoot when the wild boar comes?

A farmer's uncle planted a large area of corn. The corn is about to ripen! But it was eaten by wild boar. In the past, wild boars were allowed to fight when they came, but now with the wildlife protection law, they can't fight! But if you don't open it, it will ruin the crops. To this end, the farmer's uncle is really complaining! So, the teacher took us to have a discussion meeting.

The seminar has begun. First of all, Yang Zixuan said, "I don't think wild boar should be killed, because their number is very rare! And it's in danger of extinction. What a pity! So we shouldn't kill them! "

Then I got up and said, "I also support her opinion. Do you think, why do wild boars go down the mountain to spoil crops? " Because people destroy the environment a lot and have nothing to eat, they will eat corn and crops planted by farmers' uncles! "

But Wang Yutong said, "I object! If everyone is a farmer, will they watch their hard-earned crops be eaten by wild boars overnight? In addition, relevant information shows that the reproductive ability of wild boar is particularly strong, and seven or eight piglets were born in a few months. In this way, wild boar will steal a lot of crops, so a large area of forests and crops will be eaten clean!

Then, Grace Wai Wong said: "Then we will apply to the relevant departments to control the number of wild boars, otherwise the wild boars will go hungry to prevent them from entering the village and hurting people!"

Then the teacher said, "Yes! Everyone says everything is in good order. We should appeal to people not to kill wild animals in large numbers. If you find it, you should report it in time and take care of the environment, otherwise the last animals in the world will be our own! "

2. Composition on wild boar (seminar topic) [Edit this paragraph] Basic information Name: wild boar (figure 1) Latin scientific name: Sus scrofa English name: wild boar Chinese alias: wild boar, tapir classification: mammal, artiodactyla, pig, pig: generally 90~200 cm shoulder height: 50.

Also known as mountain pig. Strong body, short limbs, long head, small and upright ears, protruding nose like a cone, with cartilage pad (arch nose) at the top; Each foot has four toes, hard hooves, and only the middle two toes touch the ground; The tail is thin and short; Canine teeth are developed, and the upper canine teeth of males are exposed and turned up, revealing fangs; The ears of wild boar are covered with hard and sparse needle hairs, and the back bristles are long and hard; The whole body color is brown or gray-black, which varies slightly from region to region.

Morphological characteristics: the skin is gray and covered with rough dark brown or black bristles. When stimulated, it stands on the neck to form a lock of bristles, which may develop into 17 cm/6.4 inches long. Males are bigger than females.

Piglets have stripes, thick and thin hair, mane almost from neck to ass, small ears, long mouth, small head and abdomen, high and thin feet and black hooves. The back is straight and not concave, the tail is shorter than that of domestic pigs, and the teeth of male wild boar are sharp and developed.

Pure wild boar and special wild boar are mainly manifested in the size of ears, mouth, back, feet and abdomen. The coat color of wild boar (Figure 2): grayish black or brown (brownish red). Life span: 10~2 1 year, which will be longer under artificial feeding conditions.

Protection level: national third-class protected animals. This species has been listed in the List of Terrestrial Wild Animals under National Key Protection or with Important Economic and Scientific Research Value issued by the State Forestry Administration in August 2000 1.

Distribution: Wild boar is widely distributed in Eurasia, including East Asia, Southeast Asia (Indo-China Peninsula, Greater sunda islands and lesser sunda islands), Japanese archipelago, southern Siberia, Central Asia, South Asia, Middle East, North Africa and Mediterranean coast, southern Scandinavia, Central and Eastern Europe, Western Europe, Iberia and the British Isles, and introduced to New Guinea, Solomon Islands, New Zealand and North America. It is distributed all over the world except Australia, South America and Antarctica.

Species status: it is common in some areas, with strong viability and almost no natural enemies, and some areas are agricultural pests. Medicinal value of wild boar belly: wild boar belly is pig stomach. According to Compendium of Materia Medica, it is mild in nature and sweet in taste, and has the effects of stopping gastritis, invigorating stomach and tonifying deficiency.

Wild boar with thick fur and hard skin has a variety of feeding habits, including bamboo shoots, herbs, birds, eggs, mushrooms, rabbits, mountain rat, poisonous snakes and centipedes. Although scientists haven't reached a unanimous conclusion about whether wild boar is immune to toxins, judging from the fact that wild boar didn't die because of eating poisonous food, wild boar's stomach can be said to be immune to all toxins.

It is said that after the wild boar swallows the poisonous snake, the poisonous fangs of the poisonous snake will bite the inner wall of the wild boar's stomach, and the wild boar's stomach soaked in various Chinese herbal medicines for a long time has a set of ingenious tricks to cure the wound, which will produce granulation tissue at the base of the wound, and then form fibrous tissue and scar tissue, leaving "boils" on the gastric mucosa on the stomach surface. The more boils, the higher its medicinal value. Modern medical experiments also show that the abdomen of wild boar contains a lot of essential amino acids, vitamins and trace elements, which can help digestion and promote metabolism, especially for gastrorrhagia, gastritis, gastric ulcer and intestinal ulcer.

The belly of a wild boar has a size and some boils, which smell fishy and smelly. There are special requirements in the process of processing and eating, so that the nutrients are not destroyed.

Certificates for breeding pure wild boar: land wildlife domestication certificate and land wildlife management certificate, and the production cost is 25 yuan (specifically according to the local charging standard). [Edit this paragraph] Living habits Living habits: Wild boar (Figure 4) Wild boar is an ordinary but unpredictable animal, and generally does not come out and walk during the day.

It is not clear whether foraging in the morning and evening is a nocturnal activity. At noon, they enter the dense forest to avoid the sun, and most of them move in groups. 4- 10 A group is common, and wild boars like to bathe in muddy water. Males spend a lot of time rubbing their sides on stumps, rocks and hard river banks, thus grinding their skin into a hard protective layer, which can avoid being seriously injured in the struggle during the * * * period.

Wild boar's mane is as warm as a sweater. In summer, they will take off part of their manes to cool down.

The range of activities is generally 8~ 12 square kilometers, and most of the time activities are in familiar areas. It will be excreted at a fixed place in the center of the territory, and the height of feces can reach 1. 1 meter.

The territorial area of each group is about 65,438+00 square kilometers. In case of conflict with other groups, boars are responsible for guarding the group. When boars fight, they attack each other at a distance of 20-30 meters. Winners celebrate by gnashing their teeth and peeing to divide their territories.

The loser cocked his tail and ran away. Others caused skull fracture or were killed.

Often communicate far and near by humming, and there are as many as 7~30 species of animals per square kilometer of habitat. Feeding habits: Wild boar (Figure 5) Wild boar's food is very miscellaneous, and it eats everything that can be eaten.

Wild boar likes to live in the oak forest on the sunny slope in winter, because the sunny slope is warm and there are a lot of acorns under the deciduous layer of the oak forest, so wild boar depends on it to spend the cold winter. Once acorns are not harvested, a large number of wild boars will starve to death in the next spring, which is also the law of natural elimination of wild boars.

In summer, wild boars like to live near water sources, especially in subalpine meadows, where mountains are high and temperatures are low, and there are natural pools, so wild boars often feed here and bathe in muddy water. Populus davidiana, Betula platyphylla forest, Larix gmelinii forest and Picea crassifolia forest on shady slopes are also good places for wild boar to frequently move in summer.

The food of wild boar is much richer. Worms in grass and soil are its prey, and sometimes it steals birds' eggs, especially those of grouse, pheasant and chicken. Although the bird's nest is generally well concealed, the wild boar has a good sense of smell and can smell the nest.

Usually, the brooding female will fly out quickly, hoping to lure the wild boar out of the nest, but the wild boar will continue to look for the nest until it is found. Wild boar is not only good at preying on rabbits, mice and so on. But it is also found in scorpions and snakes, although scientists want to know whether wild boar is immune to toxins.

3. Composition about Wild Boars Eating Crops Autumn is coming, and the corn planted by farmers' uncles is about to mature. But it was eaten a lot by wild boar. The farmer's uncle complained bitterly. In the past, wild boar was killed as soon as it came. Now, with the wildlife protection law, even if wild boar came, the farmer's uncle could only sigh and feel sad. But I don't think we can kill wild boar just because we destroy crops.

You kill people for money. According to scientists' estimates, at least hundreds of wild animals have been killed and extinct by humans. If we don't protect them, the last animals in the world will be us.

Myself.

Wild boars spoil crops because the forests in their living areas are cut down and the ecological environment is destroyed. And this phenomenon just sounded the alarm for us!

So I think we can set up a fence in the wild boar's activity place, separate the wild boar from the crops, and send food to the wild boar regularly so that they can survive. Let's be tolerant and friendly, be kind to all wild animals, and thoroughly implement the policy of protecting animals so that wild animals will not become extinct again.

Can you shoot when the wild boar comes? A farmer's uncle planted a large area of corn.

The corn is about to ripen! But it was eaten by wild boar. In the past, wild boars were allowed to fight when they came, but now with the wildlife protection law, they can't fight!

5. Should wild boar play seminar composition? Should the wild boar type 600 words in the CET-4 composition daquan?

A farmer planted a large area of corn, which was almost ripe, but was eaten by wild boar. In the past, wild boar could be killed as long as it came, but now with the wildlife protection law, it can't be killed. If you don't hit it, it will ruin the crops. To this end, farmers complain bitterly.

About "Should wild boar be killed?" We had a special discussion. At the seminar, the students raised their hands actively, spoke enthusiastically and expressed their opinions. Wang said: "We shouldn't fight because wild boar is a national second-class protected animal. If we fight, wild boars will become more and more scarce, which will destroy the ecological balance! "

"Let wild boar destroy crops like this? In my opinion, I should fight. " Ge Liangming said.

"I'm still neutral," Tang said to him.

"You should stun it with an anesthetic gun and send it back to nature." Zhang Jingbiao immediately stood up and retorted: "If you are anesthetized too much, the wild boar will not wake up. The best way is to dig some traps in places frequented by wild boar. If a wild boar falls, call the relevant departments immediately and ask them to send the wild boar to the reserve. "

Wang said: "If you are anesthetized too much, killing a wild boar will also make an example."

..... In fact, it's not the fault of the wild boar, but human beings forced them to do so. Man cut down a lot of trees and invaded its territory. It eats nothing but crops. Wild boar is also reminding humans not to cut down trees!

6. The composition of six wild boars eating corn in the second volume of the fourth grade. Wild boar can't fight. Autumn is coming, and the corn planted by the farmer's uncle is about to mature.

But it was eaten a lot by wild boar. The farmer's uncle complained bitterly.

In the past, wild boar was killed as soon as it came. Now, with the wildlife protection law, even if wild boar came, the farmer's uncle could only sigh and feel sad. But I don't think we can kill wild boar just because we destroy crops.

Nature is wonderful and rich. And animals are the most precious things that human beings have.

How to appease wild animals whose lives are threatened is the primary problem of protecting animals. We can't kill wild animals just because they have made mistakes or in exchange for money.

According to scientists' estimates, at least hundreds of wild animals have been killed and extinct by humans. If we don't protect them, then the last animal in the world is ourselves.

Wild boars spoil crops because the forests in their living areas are cut down and the ecological environment is destroyed. And this phenomenon just sounded the alarm for us! So I think we can set up a fence in the wild boar's activity place, separate the wild boar from the crops, and send food to the wild boar regularly so that they can survive.

7. Composition of Piglet and Goat [Composition of Piglet and Goat] In ancient times, there was a pig and a goat. One day, the little goat was eating grass on the mountain. The little goat was eating when he suddenly saw a little wild boar. At this time, the wild boar didn't know what a lamb was, and the little goat didn't know what a wild boar was. At this time, the little goat ran to the little wild boar and said, the little wild boar said, "I am a little wild boar." My family lives in a cave on the mountain. Let's be good friends! " "The lamb said," all right. "So the lamb plays with the wild boar every day. One day, the lamb came home and said, "Mom, I made a friend yesterday. The wild boar came home and said, "Mom, I made a good friend yesterday." Mother lamb said, "what friend is it?" The lamb said, "His name is Little Wild Boar. Mother sheep said, "lamb, wild boar is very fierce." Take it home to play tomorrow, and we'll kill it. "Mom said," What friends did you make? " The little wild boar said, "it's called the composition of the little goat, the sixth grade pig and the little goat." Mother pig said, "Lambs are our favorite animals." If you bring it to our house tomorrow, we will eat it. The next day, the lamb and the pig were very unhappy. The little wild boar said, "lamb, my mother said she would eat you." The lamb also said, "My mother will kill you. "The lamb and the wild boar said," Let's kill our mother. "On this day, the lamb came home and said," Mom, the wild boar is coming. "Her mother came out and killed her. The boar killed her, too. The lamb and the wild boar said, "Mom, we really. "The lamb and the wild boar each gave birth to two babies, both of which are very cute. The old sheep and the wild boar said, "children, when you grow up, you can make friends with the little tiger." "Not every animal is terrible! Later, the lamb and wild boar really became good friends with the tiger. Zhao Zeyu wrote a 600-word composition for Piggy and Goat.

8. A 600-word composition describing animals and plants in combination with real life. Careful people will notice that the shape of the gas mask is very similar to that of a pig's mouth. Why? Does the invention of gas mask have anything to do with pig mouth? That's true.

During the First World War, the Germans fought fiercely with the British and French allied forces for the Igor region of Belgium, and the two sides confronted each other for half a year. 19 15 years, in order to break the long-term deadlock in the European battlefield, the Germans used chemical agents for the first time. They set up 5730 steel cylinders filled with chlorine gas at the front of the position, opened the bottle caps downwind of the British-French allied positions, and released 180 tons of chlorine gas. Suddenly, a piece of green smoke rose and floated to the other position at a speed of three meters per second, spreading to the position where the allied forces jumped 25 kilometers. Results 50 thousand British and French soldiers died of poisoning, and a large number of wild animals on the battlefield were poisoned one after another. But strangely, the wild boar in this area actually survived. This incident aroused great interest of scientists. After on-the-spot investigation and careful study, it was finally found that wild boars like to arch the ground with their mouths, which saved them from dying. When a wild boar smells a strong sexual smell, it arches the ground with its mouth to avoid the smell. After the soil is arched by wild boar, its particles become soft, which plays a role in filtering and adsorbing toxic gases. Because the wild boar skillfully used the gas mask given to it by nature, it was able to survive the chlorine disaster.

According to this discovery, scientists quickly designed and manufactured the first batch of gas masks. However, this kind of gas mask does not use soil as adsorbent directly, but uses activated carbon with strong adsorption ability, and the shape of pig mouth can hold more activated carbon. Although the performance of adsorbent is getting better and better now, its basic style resembling pig's mouth has not changed.

The gas mask can be said to be a masterpiece imitating the pig's mouth.

10. Wild boar spoils crops. Composition 470 words Today, all of us in Class 4/kloc-0 still have classes in the classroom as usual.

But this class is different from the usual class. Our class is a discussion class. The discussion is 1. Wild boar destroyed the crops. Now there is a wildlife protection law, no matter whether you fight or not.

2. Whether used batteries can be littered anywhere, etc. Now let's just talk about the first topic, "Wild boar ruined crops. Now we have a wildlife protection law, whether we fight or not. "

I believe that many farmers' friends are troubled by the problem that wild boar steals crops without shooting. Today, let me solve this mystery for you. At the beginning of the seminar, the teacher asked us to raise our hands and vote whether wild boar should be killed or not. Most wild boars should be beaten, and only three or two people choose not to fight.

The teacher smiled and said, "Now let's discuss it!" I saw only a pair of small hands shaking back and forth in the classroom at this time, and the others were inconspicuous. "Sun Wenzeng, tell me about it." "I think wild boar should be beaten. On the one hand, there is no protection for wild boar in the wildlife protection law, only tigers and pandas are protected.

Second, it should be punished for stealing crops. It's full and we're hungry. ""well! That's right. "

"Go on, there's another classmate to talk about." Hu was eager to try, but kept saying, "Teacher, I was called by the teacher."

"good! Hu Yuyu, let's talk about it! " "I like Sun Wenzeng's idea that if the wild boar comes to steal food for the first time, it will be driven away. Wait until the second time, if it comes back, it is necessary to use the "killer" to break its back. "

I think the same as the two of them. Wild boar should give it some retribution. It doesn't come whenever it wants, leave whenever it wants, leave whenever it can, and never come back. It seems that the wild boar is going to fight. We can't let go of a "thief", but we can't wronged every good person.

This seminar was very successful, which not only helped farmers solve a problem, but also let me know another knowledge, haha! ! .
