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.

Motherly love is the spring that moistens my heart; Motherly love is the wind, soothing my soul; Motherly love is honey, sweet to my heart; Motherly love is light, which illuminates my heart; Motherly love is fire, which warms my heart.
I like tea, like its pure fragrance, like its pure color, like the taste it carries. I remember that every time I study in the evening, there is a cup of white fragrant tea besides me and books under the shadow of the lamp. When I taste it, I always feel that there is an invisible power to make people progress. This is the taste of tea, slightly bitter and fragrant. composition
Often I don't know when, my mother quietly pushed open the door, holding a cup of hot green tea in her hand and putting it in front of me. "Drink it, it's bad for your health to get cold." I took the tea slowly and took a sip gently. The feeling of warmth spread all over my body. My mother picked up a cup of tea, shook her head and smiled at me. I also looked at my mother and smiled. Time seems to have solidified at that moment, and the air is filled with warm feelings. The warmth of this moment warms my heart.
I like winter. Love its majesty, love its coolness and love its blue sky. The cold north wind killed everything. After the heavy snow, it is a fairy tale world. Glittering snowflakes fall from the branches, like dancing elves, the snow-white earth is silent. At this time, the world has become my world. Have snowball fights, make snowmen, skate and ski. My mother always gives me a good book at this time, so that I can calm down and have a rest. My mother always comes in and puts on a dress for me at this time. In the evening, I took my mother's hand and walked on the path where snowflakes were flying. The warm breath in the snow shadow warmed the surroundings. composition
Whether it's a cup of hot tea or a beautiful book, there are many warm moments, bearing the most beautiful true love in the world!
3. Warm composition theme In winter, I took out the popcorn that exploded in the microwave oven and ate it. My mother is washing clothes in the kitchen. Alas, my mother's hands are red with water. I feed the popcorn to my mother: "Mom, is it cold?" Mom said, "It's not cold. It's much better after eating popcorn. " I grabbed the popcorn and stuffed it into my mother's mouth: "Mom, eat more, so it will be warm." ?
(2) Warmth shows students' respect for teachers in the form of novels. ?
Ping just graduated from college and was assigned to this school. Today is her first class for her classmates. Before that, she had a little drum in her heart: what kind of attitude will her classmates treat her? Gently push open the classroom door and the students sit neatly in their seats. There is a paper cup filled with water in the corner of the podium, and the blackboard says "Welcome, teacher". At this moment, Ping feels so warm. ?
(3) Warmth expresses his feelings about warmth in the form of lyric prose. ?
Warmth is a feeling of the soul, which is often the expression and interpretation of love. This kind of warmth occurs in ordinary life: warmth is a child's care for his seriously ill mother; Warmth is the mother's exhortation before the wanderer travels far; Warmth is the love of giving seats to the elderly in the car; Warmth is an umbrella for teachers to send students home in rainy days. Warmth is mutual. As long as you give others warmth, others will give you warmth. ?
(4) Creating novels expressing the theme of maternal love. ?
I just graduated from middle school and was admitted to my dream university. I was finally able to leave the closed environment of my hometown and get rid of my parents' nagging. I'm just so excited. When I came home during the winter vacation, I found that my mother, who had always been indifferent to current events, was watching the news broadcast every day. I'm just very confused. Mom said it was to watch the weather forecast so that I could know what just happened outside. Always strong, just can't help but wet eyes.
Affection is the most sacred and beautiful feeling in the world, and it is the blood relationship between people. Nothing can surpass this innate greatness. The family may be ordinary, without the heroism of friendship and the vigor of love, but it is precisely because of his ordinary, a greeting and a exhortation from relatives that we can feel the deep affection.
Zhu Ziqing's Back moved me deeply and haunted me for a long time. The thought of sneaking behind my father and watching his back filled my heart with many * * * voices.
When we are far away from home, our affection is like the moon in our hometown, which is a little far apart. In the dead of night, when we are lonely and helpless, what we think most about is the warm home in our hometown, where the lights are always on for ourselves, because there are family ties that we can't give up.
Many people don't know how to cherish family ties. When family members are around, they are so cold and indifferent. They don't know why crows feed back, which is worthy of admiration. They don't understand why the desire in the eyes of orphans is so persistent. We always don't know what we have been given, and we don't know how to cherish what we have. Only when we lose it one day will we know that it is too late.
So, my friend, when you still have affection, cherish it. Don't cherish until you lose it.
4. The theme of the composition "Warm" will be the senior high school entrance examination tomorrow.
wait for
Tomorrow is the mid-term exam, but I can't calm down for a moment. It is very lonely to stay at home alone. I remember a few days ago, my mother vowed to stay with me all the time. In order to remind herself, she specially drew two big circles on the calendar. But just now, she left me cruelly and left alone. Who would have thought that a so-called happy family would be so "unfortunate"? I had to stare blankly at the night sky outside the window and wait for my mother silently.
Lose hope
"Ding-dong, Ding-dong, Ding-dong." There was a clear knock on the door three times. When I heard a familiar voice, I jumped up from my chair. I know my mother is back. I opened the door excitedly and wanted to welcome my mother into the room, but my mother said, "I forgot my key!" " "My heart is half cold, and the excitement is gone for a while.
No sooner had I sat down than the doorbell rang again. Who could it be? I opened the door in doubt. "Mom again!" She stood at the door smiling, not noticing my tight face, but still smiling, she said, "It's raining, please bring my umbrella." I handed my umbrella to my mother with a straight face. As soon as mom turned around, I slammed the door. Who would have thought that at this critical moment, my mother seems to be playing tricks on me on purpose.
feel
Before I could sit down, the doorbell rang again. I couldn't help secretly cursing myself for not being early or late. It was time to be quiet. Suddenly open the door, my god! Still mom! I said angrily, "What did you forget to bring again?" My mother didn't smile at all when she saw me like this. She touched my face with her hand and said, "I just can't change my carelessness." After that, she led me into the kitchen neatly and said, "I have prepared some snacks for you in the midterm tomorrow." Don't forget to eat at night! " "Say that finish, I took out the milk and bread I had prepared from the kitchen cabinet, saying it was breakfast tomorrow, and then I rushed into the study. It turns out that my mother prepared stationery for my exam.
I am immersed in flying thoughts, and my mother has already disappeared in the endless rain curtain. Slowly back to my desk, I found my eyes were hot.
5. What can I write about "warmth"? The theme of the composition is the warmth of late autumn, the coldness of dew and the coldness of wind. The north wind shook the old tree unscrupulously and barked at the bare treetops. The yellow leaves on the ground were rolled up by the wind and circled in the air. They just fell and were rolled up ... People's faces were full of chill.
My mother and I are walking in a quiet street. It's very cold. Even wearing a thick sweater, the north wind still comes in from the small hole in the sweater, which makes people almost breathless.
Looking at a fallen leaf swept by the wind, I can't help thinking: another tough winter! At this time, a thin figure appeared in the distance, sitting alone on the ground. Against the cold wind, we walked quickly forward, and our backs gradually became clear ... that was a beggar.
She is about 30 years old, but her brow is full of vicissitudes. She only wore thin clothes and trembled slightly in the cold wind.
Another gust of wind blew, and she held the child tighter. That's probably her son, wrapped in two quilts, snuggling in his mother's arms.
Perhaps, it was his mother who snuggled up to him. She snuggled up to the child and hugged her tightly. She couldn't wait to give half of her body temperature to the child, but forgot that she was still sitting on the freezing ground, still shaking ... At this time, another north wind roared past us with fallen leaves, as simple as grass and Buddha, and even the wood was torn off, which was extremely biting and violent. She shuddered.
However, I saw her wrap the child in the quilt again. Then, without any hesitation, she took off one of her coats and gently covered the child. Her body is like leaves in late autumn, shaking badly, but the warmth between her eyebrows and eyes can drive away the cold. She looked at the sleeping face of the child, and a warm smile appeared on her face. The fundus is infinite love and infinite warmth ... She holds the child tightly, stands up from the ground and walks away step by step ... It's just that the child in her arms is still asleep, as if she doesn't know the predicament he faces, or he knows that he will never be cold, because no matter what.
The cold wind blew, and suddenly a dress fell on me, making me feel warm. Looking back, I only saw my mother's face warm ... "Warm" is autumn.
There is already a hint of coolness in the air. Walking under the tree, a fallen leaf fell quietly.
I thought its life was over, useless and meaningless, and it was time to return to the dust. But it happened to fall on me, giving me warmth and encouragement when I was disappointed, and letting me know not to waste this life.
When I first found this leaf, I didn't even look at it. I just put it in a book. I don't even know which book I put it in. To me, it's just a small leaf that is yellow and about to turn into powder.
Because I will never know its mission, its fragility, its warmth ... the winter vacation is coming, but it also means that the final exam is coming. Of course, I am in a hurry to review. Every day, the sky is gloomy and gloomy. I'm bored to death except reviewing every day. When I think of that leaf, I often think of a sentence. I think if a leaf is meaningless, what is the meaning of that person's life? But I have been unable to answer this question. In this way, I have been reviewing with this question, and that leaf has been with me.
But I didn't do well in the exam in the end. When I was wandering around the community, the leaf suddenly fell from the book and picked it up. The leaves are not cold at this time, and now they make me feel very warm. I thought it was the only one who could listen to me quietly now! Touching this leaf, I suddenly understood that the moment it fell from the tree, just like people, it fell silently after completing its mission, which is unfair! But this is life. For it, its mission is to go to Qiu Lai and Qiu Lai, Qiu Lai in the spring; For people, it is to live well and do what you should do in your lifetime. Although life is full of misfortune, it can't be like this, because one's life can't be smooth sailing.
Thinking of this, I am full of hope for tomorrow and the next tomorrow or the day when my life ends. Maybe a small leaf can give me warmth, just listen to me quietly, just give me inspiration, but this is the warmth that a small yellow leaf that almost turns into powder can give me, that's all.
"Warm" is warm, and the world is full of warmth. Just like the sunshine in winter, although it is not strong.
But it's always memorable. We played a game: Unity Circle, Trust Sit.
All the people form a circle and sit on the lap of the man behind. We trust each other and sit on the lap of the person behind us completely at ease.
In the sky, a ray of sunshine shines on us, and we laugh. It is the mutual trust between classmates that keeps us warm! Later, everyone's legs began to hurt slightly.
The monitor sang a song for us. In our small circle, I think of a firm and melodious song.
It is this song that inspires us and keeps us warm! It's almost over, and finally someone is starting to insist. All the people greeted him eagerly.
"What's the matter with you?" "Are you all right?" "Can you hold on?" This place is full of care and friendship. It is the concern of our classmates that keeps us warm! That classmate cried and laughed.
Tears glistened with firm eyes. Bite your teeth and stick to it.
It is this classmate's determination not to be afraid of pain that keeps us warm! In such a small matter, full of trust, hard work, persistence, encouragement and unity. Everything is warm.
In winter, the faint sunshine shines into the window, which reminds me of those warm things again. "Warm" I have a warm and harmonious family, which is composed of my father, mother and me. The three of us form a family of three, which is harmonious and beautiful.
I passed on this warm chain. My mother has a fever, so I have to watch her every step. Sometimes as long as my mother has a fever of more than 38 degrees, I always secretly cry beside her. I really want to share some. Mom's illness finally recovered, and my hanging heart finally fell down.
Father came home from work, so tired that he lay in bed and rested quietly. At this time, my mother saw it, and quickly told my father to sit up, gently * * * his shoulders with his hands, and didn't rest for a while. After giving it to my father, I was tired, but I didn't say a word.
6. Warm composition, narrative thanks for paying attention to us anytime and anywhere. I thank my parents, classmates and teachers ... everything is unforgettable.
"Today's math homework is ..." Teacher Zhang is assigning math homework. I quickly copied my homework, put my notebook in my schoolbag and went home happily. After a rest, I opened my schoolbag and took out my exercise book. I was shocked at once. The small notebook I used to copy my homework is missing. Oh, no, I don't know what my homework is Now when I go back to the classroom, the blackboard must be cleaned ... I'm as anxious as an ant on hot bricks and hear "tick, tick". Ah! You can call your classmates! So I picked up the phone and was about to dial, but I hesitated. I quickly put the phone down and thought, I'll call my classmates and ask them what they would think of me. A squadron leader is still so forgetful. Thought of here, my face * * * spicy, but another thought, don't ask, I can't get the teacher's criticism for face, that's too embarrassing. So I summoned up my courage, threw my thoughts to the outside of the cloud nine, and immediately dialed the telephone of Dong Lugu. Ah! Luckily, Dong Lu is at home. She gave me an enthusiastic lecture on my homework, and I gratefully said, "Thank you, Dong Lu." Dong Lu said, "Nothing! Nothing! You're welcome. It is right for students to help each other. Goodbye! " I suddenly felt a warmth in my heart. Getting help from others is sweeter than eating honey. I thought: as long as you thank others, not only others are happy, but you are also happy. I went back to my study, picked up my pen and did my homework carefully.
You can see how important gratitude is from this little thing! Students, when you are in trouble, others help you. Did you express your gratitude? If so, sign your name on the honor roll and set an example for everyone!
