The story of the wolf and the deer

(3 June 20081)

At the beginning of last century, in a forest in the western United States, many wolves were found catching lovely deer. In people's minds, wolves are fierce and should be eliminated; Deer are kind. We should protect them and make them reproduce faster. So, the president of the United States ordered hunters to go to this forest to kill wolves.

Wolves in the forest were killed by hunters at gunpoint and almost extinct. The deer happily spread its hooves and walked carefree in the forest. After seeing it, kind people all showed gratified smiles.

However, the good times did not last long, and unexpected things happened. Because there is no fierce wolf to chase and catch, the deer get fat one by one and run harder and harder. At the same time, the number of deer is also increasing rapidly, from tens of thousands to hundreds of thousands. Not only did they quickly eat up the grass and the leaves of shrubs, but they also began to chew the bark of big trees. The green vegetation was severely damaged, and the forest gradually became haggard and yellow.

What's more frightening is that a strange disease spread among the deer. Many deer fell down, and some never got up because of hunger. Now, in this forest where it is difficult to find traces of wolves, the number of deer has dropped to thousands. Even so, they are hungry, seriously ill and struggling feebly, but in the end they can't escape from the clutches of death.

This makes people understand that the seemingly fierce wolf is not only the natural enemy of deer, but also an indispensable link in the animal "food chain" and an angel to protect the ecological balance! Since then, hunters have never deliberately embarrassed wolves, and natural selection has gradually restored its vitality.

The story of the wolf and the deer

In a forest with towering old trees and lush grass, there are a group of free deer. Recently, however, a group of wolves came from nowhere and often harassed them. The deer in the herd are very scared and worried about what will happen to them.

One day, a strange thing happened That day, the wolf came to catch the deer again. A deer was cornered. She instinctively raised her feet to fight back. Unexpectedly, she kicked a wolf in the head. The wolf's brains splashed and let out a cry, ending its life. One fell and the other jumped. The deer thought desperately, I was lucky last time, but I will die this time. God never shuts one door but he opens another, she thought. Try again! Then he kicked, and the wolf missed the deer and lost his life. None of the other wolves dared to go forward, but the deer bravely took a step forward and the children immediately dispersed in a hubbub. When the deer learned about it, they thought she was a divine deer sent by heaven to protect them, so they made her the leader.

After this incident, the wolf didn't dare to set foot in the deer, for fear of being kicked to death by the deer leader, so he had to eat some rabbits, but the rabbits ran almost as fast as the deer, and the food out of breath could only fill his teeth. The number of wolves is decreasing, while the number of deer is increasing. The deer head didn't exercise all day, and after a few years, it became a fat deer.

In that beautiful but full of fighting forest, a stray wolf came. When he saw the deer, his mouth watered. He took a fancy to the deer leader and rushed at her. When the deer stepped on it, the wolf dodged slyly and bit the deer leader. The deer saw that the wolf was so bold and ran for his life. Finally, the deer ended his life in a hurry.

Alas! Nothing can be done by luck.

2. What economic truth does the story of wolf and deer embody?

Wolves and deer

Deer and wolves lived in a nature reserve in the United States in the19th century. People didn't kill all the wolves to protect the deer. In less than two years, the number of deer increased by 10 times, but five years later, there were only 200 deer left. Finally, people had to invite Mr. Wolf again, so the deer recovered quickly.

Student activities: thinking and discussion

Teacher activities: in summary, the first story illustrates the flexibility of individual and private economy; The second story shows that the introduction of foreign capital economy can enhance the competition among various economic components, thus promoting the development of the national economy.

3. After reading the story of deer and wolf, what measures did President Roosevelt take to protect deer, and why did it lead to a large number of deer deaths?

Now this situation is counterproductive, because wolves have been eliminated. On the one hand, wolves prey on some deer, so that the total number of deer is controlled and will not breed to the extent of animal degradation; On the other hand, the deer preyed by wolves are mostly old, weak and sick, which is beneficial to the survival of the fittest and reproduction of deer. On the other hand, deer are often in a state of escape under the chase of wolves, which promotes the robust development of deer. Because wolves have disappeared, deer have no natural enemies, "lazy people" are weak, and deer herds are degraded. Moreover, wolves also stimulate the survival instinct of deer, and the "lazy" deer do not respond to danger, which makes the deer herd be killed by poachers. In order to save the evil consequences caused by the extinction of wolves, the United States formulated the plan of "inviting wolves into the house" in the 1970s. However, this plan was opposed by some people and was not implemented in time. With the improvement of people's awareness of environmental protection, the plan of "inviting wolves into the room" was finally implemented in 1995. From 65438 to 0995, the first batch of wild wolves came from Canada and were released into the Rocky Mountains. The forest was full of vitality. So wolves exist to ensure the number of deer.

The wolf chased the deer to write a composition for this story.

At the beginning of the 20th century, there were about 4,000 wild deer in the Kebaber forest in the Rocky Mountains in the western United States, accompanied by fierce wolves, which threatened the survival of the deer. For the peace of these deer, 1906, the president of the United States decided to carry out a wolf killing operation. By 1930, more than 6,000 wolves had been shot and killed. The wolf disappeared in the Kebaber forest. So the deer began to give birth there carefree and unplanned, and soon the number of deer increased to 65438+ 10 thousand. Lush deer eat all edible plants, eat weeds, destroy trees, and other animals that eat plants decrease sharply, which also makes deer fall into the predicament of hunger and disease. By 1942, the number of deer in Kebabel forest had dropped to 8,000, and most of them were sickly, and the once prosperous deer family was rapidly declining. This situation backfired, because the wolf was wiped out. On the one hand, wolves prey on some deer, so that the total number of deer is controlled and will not breed to the extent of damaging vegetation; On the other hand, the deer preyed by wolves are mostly old, weak and sick, which is beneficial to the survival of the fittest and reproduction of deer. On the other hand, deer are often in a state of escape under the chase of wolves, which promotes the robust development of deer. Because wolves have disappeared, deer have no natural enemies, "lazy people" are weak, and deer herds are degraded. In order to save the evil consequences caused by the extinction of wolves, the United States formulated the plan of "inviting wolves into the house" in the 1970s. However, this plan was opposed by some people and was not implemented in time. With the improvement of people's awareness of environmental protection, the plan of "inviting wolves into the room" was finally implemented in 1995. 1998, the first batch of wild wolves were transported from Canada and released into the Rocky Mountains, and the forest was full of vitality.

In the story of Deer and Wolves, where did President Roosevelt go wrong?

Judging the advantages and disadvantages of animals only according to human's own one-sided understanding has destroyed the biological chain of wolves, deer and forests, broken the ecological balance and caused serious consequences.

6. What anthropomorphic sentences are there in The Story of the Deer and the Wolf?

The story of deer and wolf

(1) At the beginning of the 20th century, the Cobber forest in northern Arizona, USA was still lush and full of vitality. There are about 4000 deer in the forest, and fierce wolves are their natural enemies.

The president of the United States has visited the west many times? Roosevelt hoped that the deer in Kebaber forest would be effectively protected and multiplied. He declared Kebaber Forest a national hunting reserve and decided to hire hunters to kill wolves there.

Gunshots reverberated in the forest. Under the hunter's cold gun, wolves screamed and died one after another. After 25 years of hunting, more than 6,000 wolves have been killed. Many other wild animals (such as leopards) that hunted deer in the forest were also killed.

(4) Specially protected deer became the "darling" in the kebab forest. In this "free kingdom", they grow and breed freely, eat trees freely, and live a happy life without danger and adequate food.

(5) Soon, the number of deer in the forest increased to more than100000. 100000 More than ten thousand deer are gnawing at the Middle East and the West in the forest. When the bushes are eaten up, they eat the young trees. When the young trees are eaten up, they eat the bark of the big trees ... Everything that can be eaten by deer is doomed. The green vegetation in the forest is decreasing day by day, and the yellow exposed to the earth is expanding day by day.

Disaster finally arrival deer. First, hunger caused a large number of deer to die, then the disease spread and countless deer disappeared. Two years later, the total number of deer decreased sharply from100000 to 40000. By 1942, there were less than 8,000 sick deer left in the whole kebab forest.

(7) Roosevelt never imagined that the vicious man he ordered to kill was actually the protector of the forest! Although wolves eat deer, they keep the deer population stable. This is because wolves can control the total number of deer in the forest at a reasonable level after eating some deer, so that the forest will not be ruined beyond recognition by deer. At the same time, most of the deer eaten by wolves are sick deer, which effectively controls the threat of disease to deer. Once the number of deer that Roosevelt is determined to protect exceeds the limit that the forest can bear, it will destroy the stability of the forest ecosystem.

(8) This seems to be contrary to people's understanding of wolves and deer. In any nation, wolves almost always have the reputation of bullying the weak, such as the story of "Big Wolf" in China and "Little Red Riding Hood" in the west. Deer are almost always the embodiment of beauty and kindness. Wolves are ferocious and should be eliminated. Deer are kind, so we should protect them. Roosevelt's policy of protecting deer is based on this habit and the principle of fairy tales.

(9) The series of stories in the kebab forest show that different creatures living on the same earth are interdependent and interrelated. It is sometimes a serious mistake to judge the quality of animals only by human's own one-sided understanding. The forest needs both deer and wolves. People must respect this relationship between animals and even the whole biological world.

7. The story of deer and wolf tells us ———.

At the beginning of the 20th century, the kebab forest in northern Arizona, USA, was still lush and full of vitality. There are about 4000 deer in the forest, and the fierce and cruel wolf is the enemy of the deer.

US President Barack theodore roosevelt hopes that deer in Kabbah Forest will be effectively protected and breed more. He declared the kebab forest a national hunting reserve and decided that * * * would hire hunters to kill wolves there.

Gunshots echoed in the forest. Under the hunter's cold gun, the wolf screamed one after another and died. After 25 years of hunting, thousands of wolves have been killed. Other wild animals (such as leopards) that hunt deer in the forest are also hunted in large numbers.

The specially protected deer became the "darling" in Kabbah forest. In this "free kingdom", they grow and breed freely, eat trees freely, and live a happy life without danger and adequate food.

Soon, the number of deer in the forest increased, and the total number exceeded100000. More than 100,000 deer are eating in the forest. When the bushes are eaten up, they will chew the young trees and then the bark of the big trees ... All plants that can be eaten by deer are born to die. The green vegetation in the forest is decreasing day by day, and the yellow color exposed from the earth is expanding day by day.

Disaster finally befell the deer. First, hunger caused a large number of deer to die, and then the disease spread and countless deer disappeared. Two years later, the total number of deer dropped sharply from100000 to 40000. By 1942, there were less than 8,000 sick deer left in the whole Kaibabu forest.

Roosevelt never imagined that the evil wolf he ordered to kill was actually the protector of the forest! It seems cruel for wolves to eat deer, but it keeps the deer population stable. This is because wolves can control the total number of deer in the forest within a reasonable range after eating some deer, and the forest will not be ruined beyond recognition by deer. At the same time, wolves eat mostly sick deer, which effectively controls the threat of disease to deer. Once the number of deer that Roosevelt is determined to protect exceeds the limit that the forest can carry, it will destroy the stability of the forest ecosystem and bring huge ecological disasters to the forest. In other words, too many deer will be the chief culprit in destroying forests.

This seems to be contrary to people's understanding of wolves and deer. In fairy tales, wolves are almost always notorious for bullying the weak. For example, the story of the "Big Wolf" in China and the story of "Little Red Riding Hood" in the West. Deer are almost always the embodiment of beauty and kindness. Wolves are ferocious, so they should be eliminated; Deer are kind, so they should be protected. Roosevelt's policy of protecting deer is based on this customary view and fairy tale principle.

This series of stories of kebab forest shows that every creature has its own role in the ecological "stage". Deer and wolves are needed in the forest It is sometimes a serious mistake to judge the quality of animals only by human's own one-sided understanding.

8. The story of deer and wolf in the seventh paragraph.

However, because (wolves prey on some deer), (deer's mass reproduction) is avoided, and because (the total number of deer) is controlled, the forest will not be destroyed, so it has become the "hero" of the forest and deer. Deer are said to be the "culprit" because (after the wolf was eliminated, deer were bred without restriction, and forest vegetation was seriously damaged, which brought huge ecological disaster to the forest), and at the same time (the number of deer exceeded the limit that the forest could bear, and hunger led to a large number of deer deaths and epidemic diseases), the virus spread rapidly, and most of the deer died, so killing wolves did not protect the deer.

The story of deer and wolf. Is the deer protected? The result is! Start (a disease)

number

Overkilling wolves and deer have no natural enemies, which destroys the racial stability of deer. At the same time, wolves eat mostly sick deer, which effectively controls the threat of disease to deer. Therefore, killing wolves excessively hurts deer.
