How do woodpeckers protect themselves?

Question 1: What should we do to protect these lovely woodpeckers? Please tell us your good ideas 1. Cut down fewer trees, plant more trees, and protect their living environment

2 .Tie rotten wood to the tree and let the woodpeckers build their own nests

3. Post promotional slogans

Question 2: If you are cunning and insidious, you are just protecting yourself; What does it count if you don’t harm others? It shows that you don't really trust other people.

Question 3: Ideas for the design of the science lesson plan for protecting throats in large classes:

Most of today’s children are only children, and they are pampered and pampered at home. In this way, young children develop invisible Because of the habit of relying on their parents, they don’t know how to take care of themselves. They don’t understand that what they do will hurt themselves, and they don’t know how to protect themselves. In response to this, I designed a lesson on how to protect the throat. First, I used interesting stories to attract the children's attention. Through communication with the children, I learned the important methods of protecting the throat, in order to promote the formation of good habits in young children.

Activity goals:

1. Understand that the vocal cords are important organs for producing sounds, are fragile, and play an important role in human health.

2. Know the important ways to protect your throat and develop good habits to protect your throat.

Activity preparation:

Bird pictures, story music, children’s songs, ppt

Activity process:

1. Tell stories to arouse children’s interest . (The story of the woodpecker, the song of the woodpecker is so beautiful, the woodpecker loves singing the most)

(1) The teacher shows the picture and asks the children to name the food: Look, what did the teacher bring today? (Story to attract children's attention)

(2) Guess: why the woodpecker doesn't sing. (Teacher discusses with children)

(3) Let’s listen to the following story together and we will understand (explain why the woodpecker stopped singing through the story).

2. The teacher tells the story and asks questions to help the children understand the main plot of the story, focusing on how the woodpecker damages the vocal cords.

3. Do you know where the sound comes from in the body?

(1) Children look for it on their bodies.

(2), lead the children to whisper: "Sound, come out quickly."

(3) The children said: When the sound is about to come out, the teacher shows the picture of the vocal cords.

(4) The teacher speaks in the tone of the vocal cords (the vocal cords introduce themselves, I am the mother of the voice, I vibrate to produce the sound). Where did it come from?

(5) The teacher said: Children know how sounds are produced.

(6) The teacher will help the children to verify whether they have found the right one. (Experiment: Put the child's hand on the neck and say: Voice mother, the result is vibrating)

(7) Then the teacher said: When the mother of the vocal cords left, she told the teacher that the vocal cords were very thin and needed protection from the children. Do children want to know how thin their vocal cords are? (Show food instead of vocal cords)

(8) Show pictures of the vocal cords when they are not making sounds and pictures of the vocal cords when they are making sounds, and explain to the children.

4. Do children know how to protect their throats?

(1) Describe positive (correct) and negative (incorrect) examples respectively, encourage children to judge which children did it right and which children did it wrong, and explain the reasons for the right and wrong judgments.

(2) By judging right from wrong, children can learn to pay attention and remember for a long time to guide their future behavior and not make mistakes.

5. The teacher repeated the summary: do not eat food that is too spicy or salty; do not drink boiled water that is too hot, and do not eat cold drinks that are too cold; both staple and non-staple food should be soft and delicate foods; Don't eat fried peanuts, popcorn, crispy rice, nuts and fried hard and dry foods; don't be picky about food; don't run or sing in the wind; don't take a shower immediately when you sweat a lot; exercise more; don't shout loudly, learn to Speak softly.

6. The ending of the children’s song (repeated review serves as a summary).

Activity extension: Find more ways to protect the throat, and communicate the knowledge of throat protection with children.

Children's Song:

My voice is very useful, and I rely on it to speak and sing.

It doesn’t like it if it’s too cold or too hot, but it’s hurt if it’s too dry or hot.

Protecting your voice is very important and you must remember it from an early age.

Question 4: Protection measures for endangered species Wild animal and plant resources are strategic resources for human survival and sustainable social and economic development. Not only do they provide the support systems that sustain humanity, they are the basis for many industries and new pharmaceutical industries, and they are part of the world's natural capital. The reduction of wildlife resources means the loss of economic opportunities for natural capital resources that are the basis for social and economic development. Therefore, protecting wildlife resources is not only an environmental issue, but also a broader issue of sustainable development capabilities. Countries around the world attach great importance to the protection of wild animal and plant resources and have formulated relevant policies and regulations. 1. EU Biodiversity Conservation Plan The strategic goal of the EU's biodiversity conservation is to fundamentally predict, prevent and solve the causes of significant reduction or loss of biodiversity, so as to reverse the trend of biodiversity reduction or loss and enable Species and ecosystems (including agro-ecosystems) within and outside the EU territory are in a satisfactory state of conservation. The EU Biodiversity Conservation Strategy lays out a clear action framework and stipulates overall and sectoral goals. It mainly includes the following four contents: first, the protection and sustainable use of biological diversity; second, sharing of benefits generated from the use of genetic resources; third, research, identification, monitoring and information exchange; fourth, education, training and raising public awareness of protection . After the EU Biodiversity Strategic Action Plan was formulated, the British government established the British Biodiversity Leadership Group to provide strategic guidance for the UK's biodiversity protection work; then four leaders were established in England, Northern Ireland, Scotland, and Wales. The team is responsible for monitoring the implementation of each action plan and conducting work such as raising public awareness and education and training. 2. Relevant laws and regulations to protect endangered species in the United States. The United States has adopted many legislations to protect endangered species, such as the Endangered Species Act, the Migratory Bird Treaty Act, the Fish and Wildlife Cooperation Act, the National Wildlife Refuge Management Act, and the North American Wetlands Protection Act. Law etc. The most important of these is the Endangered Species Act. The Endangered Species Act prohibits the harvesting of state-listed species without a permit. But the issuance of a companion capture permit allows property owners to conduct otherwise lawful economic development activities if endangered species are present on their property. It also provides a way for management departments to develop creative partnerships with the public and private sectors to achieve balanced and comprehensive development of endangered species. For example, the International Paper Company in the United States developed a habitat protection plan to protect the endangered red-cockaded woodpecker on the company's southeastern land in order to harvest the wood used as raw material for its paper production. The plan describes the impact of clearcutting on red-capped woodpeckers and measures to mitigate the impact. Measures include establishing nearly 5,300 acres of habitat, home to 25 to 30 individuals of this woodpecker family, to increase the woodpecker population. A survey in the United States shows that at least 80 species listed on the state's national inventory live on private land. Recognizing the importance of involving private landowners in endangered species conservation, management has developed a series of policies to promote collaboration with landowners. These policies include: Candidate Species Conservation Agreements, which provide incentives for permit applicants to protect unlisted species in habitat conservation plans.

The advantages of this are: first, it provides early protection for many species, thereby avoiding their listing; second, because candidate species are protected, it reduces the number of unlisted species after the license is issued. A situation in which a species is listed, requiring modifications to the habitat conservation plan. The number of habitat conservation programs in the United States is increasing rapidly. Only 14 habitat protection plans were approved before 1992, but as of February 23, 2001, the management department had issued more than 343 accompanying capture licenses, and its habitat protection plans covered more than 20 million acres of land. , which protects 200 listed species and many unlisted species. 3. Some management methods for the commercial use of wild species in Australia. In Australia, the biggest threat to wild species is the clearance of habitats. Individual farmers, ranchers, or developers often clear native vegetation to increase the use value of their land, thereby removing habitat for wild species. Therefore, many believe that the future protection of Australia's biodiversity depends largely on finding a mechanism, particularly economic incentives, to enable the effective protection and restoration of natural habitats on private land. . Australia believes that from its experience at home and abroad, the commercial use of wild species can be one such mechanism if managed appropriately. Some experiences in Australia show that giving endangered...gt;gt;

Question 5: How to protect endangered species? Protection and utilization of wild species in some Western countries

1 ． Management methods for protecting wild fauna and flora resources in some Western countries

Due to economic development, developed countries have realized the significance of protecting wild flora and fauna earlier, and have therefore begun to speak out loudly since the 1960s. However, we cannot help but regret to see that in order to protect their own wild flora and fauna resources, some developed countries are willing to pay high prices to purchase wild fauna and flora resources from developing countries. For immediate economic interests, some developing countries have to sacrifice resources in exchange for some foreign exchange. This practice has seriously affected the ecological balance of some areas, causing some wild animal and plant resources to become endangered.

At present, countries around the world generally act according to market rules and attach importance to economic development, while neglecting to live in harmony with nature. We must see that: excessive population expansion is mankind digging its own grave; scientific and technological development is a double-edged sword. While it promotes civilization, it also destroys nature, as revealed in the book "Silent Spring"; the destruction of market economy This culture has its progressive side, but it also has its side of destroying the environment and plundering resources.

(1) EU Biodiversity Conservation Plan

The strategic goal of the EU’s biodiversity conservation is to fundamentally predict, prevent and solve problems that will significantly reduce or lose biodiversity. reasons, in order to reverse the current trend of biodiversity reduction or loss and to bring species and ecosystems (including agro-ecosystems) within and outside the EU territory into a satisfactory state of protection.

The EU Biodiversity Conservation Strategy lays out a clear action framework and stipulates overall goals and sectoral goals. It mainly includes the following four contents: first, the protection and sustainable use of biological diversity; second, sharing of benefits generated from the use of genetic resources; third, research, identification, monitoring and information exchange; fourth, education, training and raising public awareness of protection .

(2) Relevant regulations for the protection of endangered species in the United States

The United States has adopted many legislations to protect endangered species, such as the Endangered Species Act, the Migratory Bird Treaty Act, the Fish and Wildlife Animal Cooperation Act, National Wildlife Refuge Management Act, North American Wetlands Conservation Act, etc. The most important of these is the Endangered Species Act.

The Endangered Species Act prohibits the harvesting of state-listed species without a permit. But the issuance of a companion capture permit allows property owners to conduct otherwise lawful economic development activities if endangered species are present on their property.

For example, the International Paper Company in the United States developed a habitat protection plan to protect the endangered red-cockaded woodpecker on the company's southeastern land in order to harvest the wood used as raw material for its paper production. The plan describes the impact of clearcutting on red-capped woodpeckers and measures to mitigate the impact. Measures include establishing nearly 5,300 acres of habitat, home to 25-30 members of this family, to increase the woodpecker population.

(3) Some management methods for the commercial use of wild species in Australia

Some Australian experiences show that giving endangered wild species a value will lead to the destruction of the species rather than having no commercial value. Greater protection. For example, possums native to Australia have been commercially harvested at high levels for decades for their meat for domestic consumption and export. But instead of decreasing, their number has increased significantly. For another example, the indigenous people on Basstrait Island in Australia have commercially captured gray shearwaters to obtain their meat, oil and feathers for local use or export. However, the number of gray shearwaters is still increasing. This is all because commercial harvesting plays a major role in protecting the habitats of these wild animals.

The above examples illustrate that landowners can only protect habitats if they can benefit from the wildlife in them. Therefore, natural habitat should be viewed as an economic resource because it has applications and competes with other land uses. Only by considering it as having economic value can it be fully respected and protected.

Australian experience in managing wild species shows that technically sustainable harvesting or hunting is possible.

The key question is whether *** can harness the economic and social forces that could play a damaging role. Ensuring that resource owners see the economic benefits of well-managed wildlife trade is one of the most important factors. Therefore, the challenge for relevant agencies, wildlife commercial use entrepreneurs and animal protection groups is how to manage commercial applications to mitigate risks and achieve the greatest degree of biodiversity protection and sustainability. application.

2. Some Western countries protect their own resources at the expense of other countries' resources

The international community has... How do you protect yourself in the face of sudden "disasters"? What does this mean? Titmouse chose to tell his friends about the matter, and then everyone worked out a solution together. This shows that we need to help each other to solve the problem.

Question 7: The behavior of the woodpecker, known as the "forest doctor", in treating diseases of trees is (　) A. Defensive behaviorB. Foraging behavior C. Therapeutic behaviorD. Attack behavior A. Defensive behavior: In order to protect oneself, various behaviors to defend against enemies are defensive behaviors. Such as running away, pretending to be dead, releasing odor, protective color, warning color, body defense, etc., A is wrong. B. Foraging behavior: It is the behavior of animals to obtain the food they need for survival through various methods. The behavior of the woodpecker, known as the "forest doctor", in treating diseases on trees is to obtain food and maintain survival, so it is a foraging behavior. B is correct. C. The behavior of the woodpecker, known as the "forest doctor", in treating diseases on the trees is not a therapeutic behavior. , C is wrong. D. Aggressive behavior: Animals of the same species often attack or fight each other due to competition for food, mates, territory or nest areas, so D is wrong.

Question 8: How to protect the stomach? As the saying goes, three-part cure means seven-part nourishment, which is more suitable for people with weak stomach.

1. Eat less fried food: this kind of food is not easy to digest. It will increase the burden on the digestive tract. Eating more will cause indigestion and increase blood lipids, which is harmful to health.

2. Eat less pickled foods: These foods contain more salt and some harmful substances. Carcinogens, it is not advisable to eat too much.

3. Eat less raw and cold foods. Foods with strong irritating properties: Raw and cold foods with strong irritating properties have a strong irritating effect on the gastrointestinal mucosa and can easily cause inflammation. Diarrhea or inflammation of the digestive tract.

4. Eat regularly: Studies have shown that eating regularly and quantitatively can form a conditioned reflex, help secretion of digestive glands, and be more conducive to digestion.

5. Regular and quantitative meals: Eat a moderate amount of food at each meal, and have three regular meals a day. At the specified time, regardless of whether you are hungry or not, you should take the initiative to eat to avoid being overly hungry or overfull.

6. Appropriate temperature: The temperature of food should be "not hot, not cold".

7. Chew slowly: to reduce the burden on the gastrointestinal tract. The more times food is chewed fully, the more saliva is secreted, which has a protective effect on the gastric mucosa.

8. Timing of drinking water: The best time to drink water is in the morning on an empty stomach and 1 hour before each meal. Drinking water immediately after a meal will dilute gastric juice, and soaking rice in soup will also affect the digestion of food.

9. Pay attention to prevent cold: cold stomach will damage the function of the stomach, so be careful to keep the stomach warm and avoid cold.

10. Avoid ***: Do not smoke, because smoking constricts the blood vessels in the stomach, affects the blood supply of gastric parietal cells, reduces the resistance of the gastric mucosa and induces gastric disease. You should drink less alcohol and eat less spicy food such as chilies and peppers.

Maintenance methods:

1) Warmth maintenance: After the cool autumn, the temperature difference between day and night changes greatly. Pay special attention to keeping the stomach warm, add clothes in time, and cover yourself with quilts when sleeping at night to prevent A cold in the abdomen may cause stomach pain or aggravate an old illness.

2) Dietary care: The diet should be warm, soft, light, vegetarian, and fresh. It should be done regularly and quantitatively. Eat small meals frequently so that there is often food and gastric acid in the stomach to neutralize, thereby preventing It erodes the gastric mucosa and ulcer surface and aggravates the condition.

3) Food taboos: Pay attention to taboos and avoid eating food that is too cold, too hot, too hard, too spicy, or too sticky. You should also avoid overeating, quit smoking, and alcohol. In addition, you should pay attention to the method of taking the medicine when taking it. It is best to take it after meals to prevent damage to the gastric mucosa and worsen the condition.

4) Peace of mind: Pay attention to mental hygiene, maintain a happy spirit and emotional stability, and avoid tension, anxiety, anger and other negative emotions. At the same time, pay attention to the balance between work and rest to prevent excessive fatigue from affecting the recovery of stomach problems.

5) Exercise and health care: Gastrointestinal patients should take into account their own physical signs and strengthen moderate exercise to improve the body's disease resistance, reduce the recurrence of disease, and promote physical and mental health.

6) Pay attention when eating: eat at regular intervals, chew slowly, and relax. Take a short rest after a meal before starting work. Eat small meals frequently to avoid gastric bloating or hyperacidity. Excessive gastric acid may back up into the esophagus and damage the esophageal mucosa. In addition to three meals, add a snack each in the morning, afternoon and before going to bed. Eat a moderate diet - consume a wide variety of foods from the six major food groups at each meal to obtain balanced nutrition. Do not exclusively eat foods with high starch content. Don't lie down to rest after a meal.
