2. Tie the rotten wood to the tree and let the woodpecker build its own nest.
Put up propaganda slogans
Question 2: What if you are cunning and insidious just to protect yourself and don't hurt others? It means you don't trust others very much.
Question 3: the design idea of teaching plan for large class sound protection department;
Nowadays, most children are only children, and they are spoiled at home. In this way, children form the habit of relying on their parents invisibly and will not take care of themselves. If they don't know what they are doing, they will hurt themselves, let alone protect themselves. In view of this, I designed a lesson on how to protect my voice. First of all, I attract children's attention through interesting stories. Through communication with children, I learned important ways to protect my voice, thus promoting children to form good habits.
Activity objectives:
1. Understand that vocal cords are important organs for voice production, which are fragile and play an important role in people's health.
2. Know the important ways to protect your voice and form a good habit of protecting your voice.
Activity preparation:
Bird pictures, story music, children's songs, ppt
Activity flow:
1, telling stories arouses children's interest. Woodpecker's story, woodpecker's song is beautiful, woodpecker loves to sing.
(1) The teacher shows the pictures and asks the children to name the food: Look, what did the teacher bring today? (Stories that attract children's attention)
(2) Guess why woodpeckers don't sing. (Teachers and children discuss)
(3) Let's listen to the following story to understand (explain why woodpeckers stopped singing through the story).
2. The teacher tells stories and asks questions to help children understand the main plot of the story, focusing on how woodpeckers hurt vocal cords.
Do you know where the sound comes from?
(1) The child is looking for it on him.
(2) Lead the child to whisper: Come out quickly.
(3) Children say: The teacher plays out the pictures while playing them aloud.
(4) Where does the teacher speak in the tone of vocal cords (vocal cords introduce themselves, I am the mother of sound, and I vibrate to produce sound)?
(5) The teacher said in a tone: Children know how the sound is generated.
(6) the teacher helps the child to verify and see if the child is looking for it. (In the experiment, the children put their hands on their necks and said, "Mom's voice is vibrating."
(7) Then the teacher said: When the vocal cord mother left, she told the teacher that the vocal cords were very thin and needed the protection of the children. The children want to know how thin the tape is. (Show food instead of vocal cords)
(8) Show pictures of vocal cords when there is no sound and pictures of vocal cords when there is sound, and explain them to children.
4. Do children know how to protect their voices?
(1) Describe positive (correct) and negative (incorrect) cases respectively, encourage children to judge which children did right and which children did wrong, and explain the reasons for judging right and wrong.
(2) By judging right and wrong, let the children know how to pay attention to and remember for a long time, so as to guide their future behavior and know when they are wrong.
5. The teacher repeatedly summarizes foods that are not eaten or are too spicy and salty; Don't drink too hot water, don't eat too cold cold drinks; Both staple food and non-staple food should be soft and fine food; Do not eat fried peanuts, popcorn, crispy rice, nuts and fried hard food; Not picky about food; Don't run and sing in the wind; Don't take a bath immediately when you sweat a lot; Should exercise more; Don't shout loudly, learn to speak softly.
6, the end of children's songs (repeated review plays a summary role).
Activity extension: find more ways to protect your voice and exchange knowledge with children about protecting your voice.
Children's songs:
My voice is very useful. I use it to talk and sing.
It doesn't like being too cold and too hot, too dry and too spicy.
It is very important to protect your voice. You must remember it when you are young.
Question 4: Protection measures for endangered species Wild animal and plant resources are strategic resources for human survival and social and economic sustainable development. They not only provide a support system for human survival, but also are the foundation of many industries and new pharmaceutical industries, and are also an integral part of the world's natural capital. The reduction of wildlife resources means the loss of economic opportunities of natural capital resources as the basis of social and economic development. Therefore, protecting wildlife resources is not only an environmental problem, but also a broader sustainable development problem. All countries in the world attach great importance to the protection of wildlife resources and have formulated relevant policies and regulations. 1. EU biodiversity conservation plan The strategic goal of EU 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 make species and ecosystems (including agro-ecosystems) within and outside the EU in a satisfactory state of protection. The EU Biodiversity Conservation Strategy has formulated a clear framework for action, and set the overall goals and departmental goals. It mainly includes the following four contents: first, the protection and sustainable utilization of biodiversity; The second is to share the benefits brought by the utilization of genetic resources; Third, research, evaluation, monitoring and information exchange; Fourth, educate, train and raise public awareness of protection. After the EU biodiversity strategic action plan was formulated, the UK biodiversity leading group was established to provide strategic guidance for biodiversity protection in the UK. Subsequently, four leading groups were set up in England, Northern Ireland, Scotland and Wales to supervise the implementation of various action plans, raise public awareness and carry out education and training. 2. Laws and regulations related to the protection of endangered species in the United States The United States has enacted many laws to protect endangered species, such as the Endangered Species Act, the Migratory Birds Treaty Act, the Fish and Wildlife Cooperation Act, the National Wildlife Sanctuary Management Act, and the North American Wetland Protection Act. Among them, the most important is the Endangered Species Act. The Endangered Species Act prohibits the capture of species listed in the national list without a license. However, the issuance of incidental fishing licenses allows asset owners to engage in other legal economic development activities when endangered species exist in their assets. At the same time, it provides a way for management to develop creative partnership with public and private sectors, so as to realize the balanced, comprehensive and orderly development of endangered species. For example, the international paper company in the United States has made a habitat protection plan to cut down the wood used as its paper raw material and protect the endangered red-hat woodpecker on the land in the southeast of the company. The plan describes the impact of cutting down trees on the red-hat woodpecker and the measures to mitigate the impact. Measures include establishing nearly 5,300 acres of habitats inhabited by 25-30 woodpeckers to increase the number of woodpeckers. A survey in the United States shows that at least 80% of the species in the list of * * * States live on private land. Recognizing the importance of involving private landowners in the protection of endangered species, the management department has formulated a series of policies to promote cooperation with landowners. These policies include: candidate species protection agreement, which encourages permit applicants to protect species not listed in the habitat protection plan. The advantages of this are: first, it can provide early protection for many species, thus avoiding them from being listed in the catalogue; Second, because the candidate species are protected, it can reduce the situation that a species that is not listed in the catalogue is included after the license is issued, and thus it is necessary to modify the habitat protection plan. The number of habitat protection projects in the United States has increased rapidly. Before 1992, only 14 habitat protection plans were approved, but by February 23, 2006, 5438+0, the management department had issued more than 343 incidental fishing licenses, and its habitat protection plans covered more than 20 million acres, protecting 200 listed species and many unlisted species. 3. Some management measures for commercial utilization of wild species in Australia, the biggest threat to wild species is habitat clearance. In order to improve the land use value, individual farmers, ranchers or developers often remove native vegetation, thus removing the habitat of wild species. Therefore, many people believe that the future biodiversity protection in Australia depends largely on finding a mechanism, especially the economy, to effectively protect and restore natural habitats on private land. Australia believes that the commercial application of wild species can be one of the mechanisms under proper management from the experience at home and abroad. Some experiences in Australia show that giving endangered >>
Question 5: How to protect endangered species? Protection and Utilization of Wild Species in Some Western Countries
1. Management measures to protect wildlife resources in some western countries
Due to economic development, developed countries first realized the significance of protecting wild animals and plants, so they began to speak out in the 1960s. However, we can't help but regret to see that some developed countries are willing to buy wildlife resources from developing countries at high prices in order to protect their own wildlife resources. Some developing countries have to exchange some foreign exchange at the expense of resources for immediate economic benefits. This practice has seriously affected the ecological balance in some areas, leading to the extinction of some wildlife resources.
At present, all countries in the world generally act according to market rules, attach importance to economic development and ignore the harmony with nature. We must see: the over-expansion of population is that human beings dig their own graves; The development of science and technology is a double-edged sword, which promotes civilization and destroys nature at the same time, just as the book Silent Spring reveals. The market economy is very destructive. This kind of culture has its progressive side, but it also destroys the environment and plunders resources.
(1) EU biodiversity conservation plan
The strategic goal of biodiversity conservation in the EU is to fundamentally predict, prevent and solve the causes of significant reduction or loss of biodiversity, so as to reverse the current trend of biodiversity reduction or loss, and make species and ecosystems (including agro-ecosystems) within and outside the EU in a satisfactory state of protection.
The EU Biodiversity Conservation Strategy has formulated a clear framework for action, and set the overall goals and departmental goals. It mainly includes the following four contents: first, the protection and sustainable utilization of biodiversity; The second is to share the benefits brought by the utilization of genetic resources; Third, research, evaluation, monitoring and information exchange; Fourth, educate, train and raise public awareness of protection.
(2) American laws and regulations on the protection of endangered species.
The United States has enacted many laws to protect endangered species, such as the Endangered Species Act, the Migratory Birds Treaty Act, the Fish and Wildlife Cooperation Act, the National Wildlife Sanctuary Management Act, and the North American Wetland Protection Act. Among them, the most important is the Endangered Species Act.
The Endangered Species Act prohibits the capture of species listed in the national list without a license. However, the issuance of incidental fishing licenses allows asset owners to engage in other legal economic development activities when endangered species exist in their assets. For example, the international paper company in the United States has made a habitat protection plan to cut down the wood used as its paper raw material and protect the endangered red-hat woodpecker on the land in the southeast of the company. The plan describes the impact of cutting down trees on the red-hat woodpecker and the measures to mitigate the impact. Measures include establishing nearly 5,300 acres of habitats inhabited by 25-30 woodpeckers to increase the number of woodpeckers.
(3) Some management measures for commercial utilization of wild species in Australia.
Some experiences in Australia show that giving endangered wild species a certain value will bring greater protection than not having commercial value. For example, in order to obtain mink meat from Australia for domestic consumption and export, it has been caught in high-level commerce for decades. However, its number has not decreased, but has greatly increased. For another example, the aborigines of bass strait Island have been catching cranes commercially for decades to obtain their meat, oil and feathers for local use or export, but the number of cranes is still increasing. This is because commercial capture has played a great role in protecting the habitat of these wild animals.
The above examples show that landowners can only protect these habitats if they benefit from the wildlife in these habitats. Therefore, natural habitat should be regarded as an economic resource, because it has application value and can compete with other land use methods. Only when it is regarded as having economic value can it be fully respected and protected.
Australia's experience in managing wild species shows that technically sustainable harvesting or hunting is possible.
The key question is whether * * * can control the potentially destructive economic and social forces. Among them, it is one of the most important factors to ensure that resource owners see that well-managed wildlife trade has economic benefits. Therefore, for * * * related institutions, the challenge faced by entrepreneurs and animal protection groups in the commercial utilization of wildlife is how to manage commercial applications, thereby reducing risks and realizing the maximum protection and sustainable application of biodiversity.
Some western countries protect their own resources at the expense of those of other countries.

Question 6: In the titmouse article, how does the little titmouse protect itself in the face of sudden "disaster"? This explains why tits choose to tell their friends, and then we can work it out together. This shows that we need to help each other to solve the problem.
Question 7: Woodpeckers, known as "forest doctors", treat trees as () A. Defensive behavior B. Foraging behavior C. Therapeutic behavior D. Aggressive behavior A. Defensive behavior: In order to protect themselves, all kinds of behaviors to defend the enemy are defensive behaviors, such as running away, playing dead, releasing odor, protecting color, warning color, and self-defense. A mistake. B foraging behavior: it is the behavior of animals to obtain the food they need for survival through various ways. Woodpeckers, known as "forest doctors", treat trees for food and survival, so they belong to foraging behavior. B ok. C, woodpecker called "forest doctor" to treat trees is not a therapeutic behavior, C is wrong. D. Aggressive behavior: Individuals of the same species often compete for food and spouses.
Question 8: How to protect the stomach? As the saying goes, "three-point rule and seven-point support" is more suitable for people with bad stomach. . .
1. Eat less fried food: because this kind of food is not easy to digest, it will increase the burden on the digestive tract. Eating too much will cause indigestion and increase blood lipids, which is not good for your health.
2. Eat less pickled foods: These foods contain a lot of salt and some carcinogens, so it is not advisable to eat more.
3. Eat less cold food * * * Food: Food with strong cold sex has a strong * * effect on the digestive tract mucosa, which is easy to cause diarrhea or digestive tract inflammation.
4. Diet rule: Studies show that regular diet and regular quantification can form conditioned reflex and contribute to the secretion and digestion of digestive glands.
5. Regular and quantitative: eat moderately every meal, and have three meals a day at regular intervals. At the specified time, whether you are hungry or not, you should take the initiative to eat to avoid being too hungry or too full.
6. Appropriate temperature: The temperature of the diet should be "neither hot nor cold".
7. chew slowly: reduce the burden on the stomach. The more times food is chewed fully, the more saliva is secreted, which has a protective effect on gastric mucosa.
8. Drinking time: The best drinking time is before fasting in the morning 1 hour, every meal. Drinking water immediately after a meal will dilute the gastric juice, and soaking in rice will also affect the digestion of food.
9. Pay attention to cold protection: After the stomach catches cold, the function of the stomach will be damaged, so pay attention to the warmth of the stomach and don't catch cold.
10. Avoid * * *: Don't smoke, because smoking makes the blood vessels in the stomach contract, affects the blood supply of gastric parietal cells, reduces the resistance of gastric mucosa and induces stomach diseases. You should drink less and eat less spicy food such as peppers.
Maintenance method:
1) Warm care: After the autumn is cool, the temperature difference between day and night changes greatly. Pay special attention to the warmth of the stomach, add clothes in time, and cover the bedding at night to prevent the stomach from getting cold and aggravating the old illness.
2) Diet nursed back to health: The diet should be warm, soft, light, vegetarian and fresh, so as to be regular and quantitative, eat less and eat more meals, so that food and gastric acid are often neutralized in the stomach, thus preventing the erosion of gastric mucosa and ulcer surface and aggravating the condition.
3) Taboo maintenance: Pay attention to taboos, do not eat foods that are cold, too hot, too hard, too spicy and too sticky, avoid overeating, and quit smoking and alcohol. In addition, we should also pay attention to the method of taking medicine, preferably after meals, to prevent the deterioration of the condition caused by gastric mucosa.
4) Rest in peace: pay attention to mental health, keep cheerful and emotionally stable, and avoid negative emotions such as tension, anxiety and anger. At the same time, pay attention to the combination of work and rest to prevent excessive fatigue from affecting the recovery of stomach diseases.
5) Exercise health care: Gastrointestinal patients should combine their own signs, strengthen moderate exercise, improve the body's disease resistance, reduce disease recurrence and promote physical and mental health.
6) Pay attention to diet: eat regularly and quantitatively, chew slowly, relax, and take a break after meals before starting work. Eat a small amount-avoid stomach swelling or hyperacidity, which may return to esophagus and esophageal mucosa. In addition to three meals, add snacks in the morning, afternoon and before going to bed. Eat light food-eat six kinds of food every meal to get balanced nutrition. Don't just eat foods with high starch content. Don't lie down and rest after dinner.
