The hottest material in 2009: background of influenza A (H 1N 1). In March 2009, influenza A (H 1N 1) occurred in Mexico and the United States, and its virus was influenza A virus, subtype swine influenza virus H 1N 1, including swine influenza, avian influenza and human influenza. List of opinions 1. It is impossible for human beings to be kind to animals, and the harsh breeding environment provides opportunities for the growth and variation of viruses.
Humans don't care about the environment and abuse antibiotics. 2. The plundering and destruction of nature by human beings is becoming more and more serious.
Studies have proved that 66% of infectious diseases are spread by animals. 3. Theory of accelerated virus mutation: The acceleration of virus mutation and the leap of "species barrier" make the danger faced by human beings more and more serious.
Viruses are smarter than humans: viruses constantly look for human weaknesses and take advantage of them. With the continuous struggle between human beings and viruses, the fighting power of viruses is getting stronger and stronger.
5. The global public health prevention mechanism should be improved, scientific prevention needs global cooperation, and scientific and technological development needs to respect nature. 6. Climate change theory: Climate change promotes the occurrence and spread of animal infectious diseases.
Global climate change will certainly cause some bacteria to change, so that the danger of human beings is not only at the macro level, but also in the micro world. Key words of concern: man and natural environment, environmental protection, human crisis, global problems, public health introspection, biological virus, ecological plunder, man-made conspiracy, life cost. Focus interpretation: human beings are changing the earth, but behind these changes, they have caused benign qualitative changes and hidden dangers.
With the passage of time, many new diseases and terms have appeared. These seemingly unfamiliar but so familiar germs like SARS, avian influenza and influenza A (H 1N 1) suddenly hit like a hurricane, and all these are changing us. This social focus deserves our attention.
It involves man and nature, global issues, public health, ecological protection, environment, crisis, introspection, disaster, cherish, respect, shock, life, cooperation and harmony. [Application example] Title 1 Man and nature are the habitats of animals and plants, the origin of life and the source of everything for us.
Life is between heaven and earth, living in nature. We bravely walked from the wild age to the civilized century.
There is a great relationship between man and nature. In nature, human wisdom has created economic miracles, while ignorance and greed have left terrible consequences.
Now the earth has sent out painful * * *: environmental pollution, ecological deterioration and rampant viruses. All this is worth pondering.
SARS in 2003, avian flu in 2004 and influenza A today all make us think deeply about how human beings should treat nature. How do humans live in harmony with nature? Perhaps it is a simple answer: be kind to nature and live in harmony. Be kind to everything, just like being kind to our friends; Saving the earth means saving our home! The main idea of harmony between man and nature is that man and nature are interrelated, interdependent and harmonious.
Topic 2 Disaster In the face of the arrival of "influenza A H 1N 1", perhaps we think of a gray word "disaster". In fact, we have suffered countless disasters.
El Nino, greenhouse effect, global warming, tsunami, SARS, and now influenza A, every disaster here stings the fragile nerves of human beings. Why on earth is this?
Maybe it is the punishment of nature, maybe it is the punishment of the earth. What is it? Why are there so many disasters? We are considering this matter. After entering the industrial age, human beings plundered extensively, causing serious industrial pollution and obvious global greenhouse effect. The progress of mankind is based on plundering nature. Killing other species at will, seals in the Arctic Ocean are skinned, blue whales in the ocean are slaughtered, rare species in the mountains are cooked, and so on. Man's appetite is based on killing living things.
To sum up simply, environmental damage and ecological imbalance will lead to frequent disasters. Lower your head, arrogant human, and take a long-term view; Swallow your saliva, greedy human, and put your taste in a normal position, otherwise human beings can only bear the punishment of the earth themselves-disasters occur frequently.
Topic 3 introspection is the source of human progress. Lack of self-reflection is a common weakness of human beings, which is not limited to the arrogance of nature, but more importantly, there is always reason to excuse oneself for mistakes.
Abnormal climate, serious three wastes, epidemic diseases, frequent disasters and environmental deterioration caused by industry and modern social lifestyle have become hot topics and difficult problems all over the world. When people take actions one after another to solve various specific environmental protection problems, human beings need to really reflect on themselves.
Because of the arrogance of nature, environmental pollution and destruction have contributed to more bacterial variation. Human egoism and blind behavior of ignoring nature have become the sword of Damocles hanging over human heads. How many viruses mutate? How much effort will mankind have to make to reap the consequences? All this tells us that we must calm down and seriously reflect on the relationship between man and nature, the problems of natural environment, the relationship between industry and nature, and human weaknesses.
From the fundamental content, fundamental reason and fundamental relationship, we reflect on human philosophy and our humanity.
2. Write a composition on the topic of "Influenza". What should I do if there are symptoms similar to a cold and fever? What are the symptoms of influenza A (h 1n 1)?
1。 First of all, if you have a fever, be careful not to blindly take antipyretics. When antipyretics are really needed, they should be taken strictly according to the weight and controlled within a safe dose. Eating too many antipyretics is not good for your health. You should find out where the lesion is, prescribe the right medicine, and radically cure the lesion.
2。 The early symptoms of influenza A (H 1N 1) are similar to those of ordinary people, including fever, cough, sore throat, general pain, headache, chills and fatigue. Some of them may also have diarrhea or vomiting, muscle pain or fatigue, red eye or some of these symptoms. If not treated in time, this disease will lead to pneumonia, respiratory failure and even death.
3。 Note: The body temperature of high fever in the early stage of swine flu is not always higher than 39 immediately, but will gradually increase or appear repeatedly.
4。 Although many people are prone to colds, fever and other physical discomfort when autumn comes and seasons alternate, the early symptoms of influenza A (H 1N 1) are just similar to those of ordinary people, so it is difficult to distinguish them. Since swine influenza A (H 1N 1) is prevalent at present, if its symptoms are similar to some of the early symptoms of influenza A (H 1N 1), for the sake of safety, we should go to the hospital fever clinic or infectious diseases department as soon as possible to carry out influenza A (H1N/).
5。 Note: It is the epidemic period of swine influenza A (H 1N 1). You must wear a mask when you go to a hospital with a high source of infection. You should choose a standard dust mask. A thin ordinary mask can only ensure that the disease will not be transmitted to others, but it can't guarantee that you will be infected by others when you go to the hospital or see a doctor. Feel free! ! ! ! ! !
6。 I suggest that if you have symptoms similar to influenza A (H 1N 1) and feel unwell, go to a public hospital for examination immediately to avoid delaying your illness! Large hospitals are more secure, and being late will affect your health.
I hope my answer is helpful to you.
How to prevent influenza A H 1N 1?
At present, there is no development and production of influenza A preventive drug (H 1N 1) in China. Don't be credulous of the online unofficial propaganda of influenza drugs (H 1N 1).
The best preventive measure is vaccination. I suggest you get the flu vaccine of h 1n 1 early.
1。 All "centers for disease control and prevention" (health and epidemic prevention stations) and public hospitals designated by medical administrative organs can be vaccinated with influenza A vaccine H 1N 1!
2。 The specific details of vaccination can be consulted with the local "CDC" (health and epidemic prevention station) and medical administrative organs.
3。 The telephone numbers of centers for disease control (health and epidemic prevention stations) and medical administrative organs can be found in the "1 14 directory".
4。 Note: It is the epidemic period of swine influenza A (H 1N 1). You must wear a mask when you go to a hospital with a high source of infection. Standard dust masks should be selected. A thin ordinary mask can only ensure that the disease will not be transmitted to others, but it cannot guarantee that you will be infected by others on the way to the hospital and when you are vaccinated with h 1n 1 flu vaccine. Feel free! ! ! ! ! !
I hope my answer is helpful to you.
If someone around you has flu symptoms, you should pay attention to:
1。 Always open the window to keep the indoor air fresh, and go to the drugstore to buy disinfectant (there are a lot of disinfectant used to prevent influenza A (H 1N 1). Thoroughly disinfect the room, especially the door handle, wardrobe door, coffee table and sofa armrest. Tableware and tea meals should also be strictly disinfected and used by special personnel, and the system of separate meals should be advocated.
2。 Maintain good living habits, do a good job in personal hygiene, dry clothes and bedding frequently, wash your hands frequently, and clean and disinfect daily necessities frequently.
3。 When you come into contact with other family members' public goods, you must wash your hands before doing anything else. Don't wash your hands, don't touch your eyes, nose and mouth, which are easy to be infected.
4。 Drinking Radix Isatidis and other heat-clearing and detoxicating series granular tea can play a preventive and health-care role.
5。 Maintain a healthy and good attitude, take an active part in physical exercise, increase resistance and improve your immune function.
I hope my answer is helpful to you.
About the composition and epidemic situation of spring, 600 words 20 19 In the days near the Spring Festival, a kind of novel coronavirus suddenly appeared, so everyone had to stay at home and study, relax and have classes online. It turns out that a lively Spring Festival seems so monotonous.
Just wait. Waiting for the early arrival of spring. We can control the virus as soon as possible. At that time, it will be spring flowers, birds singing and flowers fragrant, spring scenery full of gardens, red flowers raining, thousands of trees blooming, grass flying, orchids blooming, willows fluttering and blue waves rippling.
Finally, after countless expectations, we are looking forward to this day. The epidemic situation has been basically controlled by medical experts in China, and spring has come quietly. Grandpa excitedly called and said that the countryside was also unsealed. One sunny day, my father took us to my hometown for a spring outing.
After lunch, I went to look for the footprints of spring. I walked leisurely. I walked to the rape field. Rape has an attractive golden color. Looking from a distance, it is dazzling. Maybe that's the color of spring. Rape also gives off a unique smell. Maybe that's the smell of spring. Hello, spring, I found you in the rape blossoms, and I also found you by the river. Holding hands, my sisters ran and sang, "Where is spring? Where is spring? Spring is in the green forest. " I started jumping when I was walking, and I was very, very happy. Now that spring has really come, it means that the days of fighting the epidemic are coming to an end. Spring is beautiful, but the process of protest is also very difficult.
Don't go out, don't go out to eat, be sure to wear a mask, always open the window for ventilation at home, wash your hands frequently, and eliminate the virus on your hands in snowy days. Don't touch the snow with your hands, because it may carry viruses in the air. Use disinfectant to disinfect after going out.
Now that the epidemic is under control, the unsealing is not relaxed, and zero increase is not zero risk. We can't let our guard down. Come on, we will win the battle.
4. What are rumors? Write a composition on the topic of rumors? Rumors are unconfirmed statements or explanations of things, events or problems that are of interest to the public and spread through various channels. According to the above definition, the rumor is not true or false, because it is unconfirmed information, so it is impossible to determine the truth or falsehood of the rumor.
Well, since the rumor is not true or false, as the philosopher said, "The news is not necessarily true, the second is not necessarily good, and the third is not necessarily unimportant, so don't say it, lest people be confused by this rumor."
What is a wise man? Baidu explained: people with ingenuity or wisdom. Everything was done by Han Feizi: "The wise man's way makes the wise man do his best." "Huai Nan Zi Zhu Shu Xun": "If things can be prepared, the wise will do it; People with power do their best. This wise man is so few. " To put it bluntly, people in power, from president to the market, are all passers-by.
So rumors stop at the wise.
Life has a direction, a fool can move mountains, a wise man cannot know, and it is not up to the wise man to decide whether it is a curse or a blessing.
In 2003, there were a lot of rumors about SARS in Beijing. Instead of investigating and controlling the epidemic in depth, the leaders increased the police force to detain those who spread rumors. As a result, the epidemic spread, many victims and so-called wise men were punished.
5. Write a composition of about 800 words with safety as the theme. Food is the most important thing for people. Food safety is a major event, which concerns people's health and lives.
The broadcast on TV and the report in the newspaper revealed the jaw-dropping truth: the foam teacups that made us drool were actually processed from the unsightly "underground factory"; That red date, in fact, is a blue winter date, soaked in the medicine, and changed color. Recently, the well-known "Sanlu milk powder", which caused a nationwide uproar, made people panic.
How can we believe that the food we eat every day is safe?
In primary school, I was always attracted by the delicious barbecue, boneless chicken fillet and stinky tofu on the way to and from school. These dazzling foods made me drool at high altitude in thousands of feet for three days, but I didn't know whether it was harmful to my health, so I had to shrink back and swallow the saliva in my mouth, and I had to stay away from these temptations. But I really don't want to eat? Absolutely not. In the final analysis, it is food safety that makes me doubt, so I am confused between "delicious" and "safe".
Just like the "Sanlu milk powder" incident, the dairy products of many dairy companies such as Yili and Mengniu were found to contain melamine, and the sales of dairy products in the market dropped sharply. People question the major brands of dairy products, and many newborn parents don't know which brand of milk powder to choose for their children!
It stands to reason that food safety is a matter of course. But now who can guarantee what food is safe? Food safety should not rely on reprinting the shelf life to muddle through, make money without conscience, and take people's health as a bet!
Food safety once again sounded the alarm, and relevant departments should pay more attention to food safety. Strengthening food safety, improving the ability of food hygiene supervision and inspection, finding hidden dangers in time and nip in the bud are the urgent tasks of relevant departments!
Where can I find safe food?
May junk food stay away from us, let healthy food accompany us and make food safety everywhere!
6. Safety-oriented 600-word composition "Safety"-an eternal topic
Pursuing fashion and advocating fashion may be a fashion. But once fashion becomes the mainstream of society, the beautiful things that originally existed in people's hearts will become the past and become eclipsed. However, "safety" is everywhere in people's production and life, and it is everywhere in our life. People should pay attention to traffic safety when going out; Pay attention to health and disease prevention safety in life; In production, we should pay attention to the safety of life and property, and so on. Therefore, "safety" is an eternal topic.
In our real life, countless facts tell us that anyone who ignores safety will pay a painful price, such as: 3.5 in Gansu and 3.23 in Baoji, warning us that illegal operation, habitual violation, empiricism and paralysis are the enemies of production accidents. The painful lesson tells us that any behavior that ignores rules and regulations will leave a painful history of blood and tears. Facts have proved that only by putting safety work in the first place can we ensure the improvement of economic benefits and the stability of social environment.
"Come to work happily and go home safely" has always been the slogan advocated by many factories and mines, which means that people can finish their day's work safely and smoothly, go home safely and reunite with their families, and at the same time express their desire to attach importance to safety at all levels. Nowadays, the extensive development of "three guarantees" further shows the concern and attention of the whole society to safety. Especially as workers in the production line, we should clearly realize the importance of safety to us. If we don't pay attention to strictly abide by the safety work rules and do a good job in safety protection, then once an accident happens, we will be the first to be hurt. Therefore, in order not to hurt ourselves, others and others, each of us should start from me, start from dribs and drabs of self-cultivation, tighten the string of safety, never relax our demands on ourselves, strictly abide by the rules, keep accidents away from us, and truly prevent accidents from happening to me and my unit.
"Safety work" is a long-term work, and we must not be sloppy and lax, let alone pose, go through the motions and bluff. If someone takes safety work seriously, they will be punished in the end. In practical work, we must stick together. We must not engage in the practice of having policies and countermeasures, and conveying and implementing the two skins. More importantly, you must never be in a state of panic in order to cope with the inspection, which will seriously affect your normal work and life, and the final result will be to harm others and yourself. It is necessary to implement and institutionalize the safety prevention work, so that everyone will supervise and be responsible, and a good atmosphere of shameful violation of regulations and glorious discipline will be widely formed, so that leaders will be present and inspections will be present, and safety work will be infiltrated into every corner from the actual work.
"Safety responsibility is more important than Mount Tai" is not imagined by anyone, nor is it an empty slogan, but is summed up through continuous practice. At present, all our work should be carried out around the center of safety. It is necessary to conscientiously implement the provisions of the Safety Law, divide safety responsibilities at different levels, strictly implement the safety responsibility system, check at different levels, and organize closely, and resolutely eliminate the signs of accidents and unsafe factors in the bud.
As the saying goes, "strictness is love, and looseness is harm." Yes, it is necessary to have a strict supervision mechanism, implement the safety law and strengthen the assessment. Those who ignore the law and discipline and dare to go against the wind and violate discipline should be dealt with severely. Never tolerate and accommodate, let those who dare to violate the rules rein in from the brink, never care about human feelings and face, and regard the implementation of safety discipline as a bargaining chip for emotional exchange.
Everything is established in advance, and it is abolished if it is not foreseen. Only by singing the theme of "safety is for production, and production must be safe" in our life and work can we truly implement safety work. In every link of practical work, there must be a strict and meticulous division of labor, careful deployment, and full preparation for various emergencies. If there is a problem, we will calmly deal with it, keep the accident scope to a minimum, and effectively avoid bloodshed and casualties.
"Safety" is an eternal topic. When peace and development become the theme of the times, security becomes more important. A peaceful and peaceful life needs security, economic take-off needs security, and the development of the times needs security more. Therefore, we will, as always, carry out the safety work to the end, truly be a model of obeying rules and disciplines, be brave in fighting against all kinds of behaviors that endanger safety, and truly "always think about safety everywhere, and everyone stresses safety in everything". Let the alarm of safety often reverberate in our ears, and let us work together to have a better tomorrow. (1540 words)
