Write a 600-word composition according to the epidemic situation.

1. 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 to study, relax and take online classes. 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, bloom was warm in spring, birds were singing and flowers were fragrant, all loves, flowers were falling like rain, trees were blooming, the grass was long with warblers, the grass was long with bluegrass, the willow was dark and the flowers were bright, and the water was 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.

2. How to write the Spring Festival in 2020 in 600 words was originally a traditional festival in China. The sudden outbreak of COVID-19 suddenly changed the atmosphere of our festival from joy to panic and anxiety. As the epidemic continues to be severe, it also brings unprecedented anxiety and worry to our daily life.

My mother bought a high-speed train ticket to grandpa's house in Xuzhou on New Year's Eve, and plans to go home on the fourth day. It was hard to get a ticket, but the day before departure, a critical epidemic broke out in Wuhan and the whole city was closed. This move canceled many people's travel plans. When we got on the bus as planned, we found that there were only a few people sitting in the seats of forty or fifty people. And everyone wears masks and stays away from each other! Our hearts can't help but add a little panic. My life in Xuzhou is also uneasy. My mother learned that there are 94 students who came back from studying in Wuhan in Xuzhou. This situation seems to be a time bomb. In response to the call of the country-squatting at home, we changed our visas in a hurry, stayed in Xuzhou for a day, and then "escaped" and went home!

After returning home, we went to the supermarket to stock up in full gear. There were 84 flavors in the supermarket, which reminded people of a serious epidemic. But there are very few things on the shelves, only a few packets of instant noodles are left. We had to make do with some and bought many other preservable foods. When I get home, my neat mother sprays disinfectant up and down, and wipes everything with disinfectant paper towels to save time! I feel obsessive-compulsive.

At this critical moment, we should keep in mind Grandpa Zhong Nanshan's protection requirements: wash your hands frequently, drink plenty of water, get plenty of ventilation, don't go out unless you have to, wear a mask when going out, and don't get together ... Many frontline medical staff are fighting in the front line, and the charity of caring people from all walks of life also inspires us. We must unite as one and do a good job of prevention and control together throughout the country in order to win this battle-try to knock down the coronavirus!

Come on! Come on! Come on!

I think infectious disease is a terrible word for some people, because it can infect each other through various channels, so people are afraid and stay away from it.

In my opinion, infectious diseases are not terrible, the key is what kind of mentality you use to look at it. Let's say that our most common infectious disease, influenza, has been plaguing people's health since ancient times.

In ancient times, it could threaten people's lives. However, our ancestors did not give in, but tasted all kinds of herbs and finally conquered it with ordinary herbs. Since the invention of chemicals, although it sometimes patronizes our bodies, we are fully capable of subduing it, and it can no longer be violent.

Let's talk about the severe SARS in our country in 2003, because there has never been such a medical history in history, so it is more difficult to treat. However, angels in white, the Chinese nation, was not intimidated, but fought against it with perseverance.

Although no cure for SARS has been found yet, after all, all SARS patients have been discharged from hospital smoothly and returned to work, and SARS has finally been overwhelmed by the spirit of the Chinese nation's unity and never forgetting death. On this day in 2005, "epidemic cerebrospinal meningitis" once again visited our beautiful home.

But can we be conquered by him? Don't! Absolutely not! Although "epidemic cerebrospinal meningitis" has a high mortality rate, it is a loser after all. Humans have formulated a plan to subdue it, as long as we take precautions, actively inject vaccines, achieve early detection, early isolation and early treatment, and face it with an optimistic attitude. I firmly believe: mankind will certainly defeat it! Human science is constantly developing, and no natural or man-made disaster can stop its development.

What's so terrible about just infectious diseases? Let's hold our heads high to meet the new challenges.

I read the composition on infectious diseases. Everyone looks pale at the mention of SARS.

Because SARS once made countless families in China go wherever they went. Speaking of the power and infection speed of SARS, it is really chilling, but no matter how powerful the virus is, it will eventually be overwhelmed by the great spirit of the Chinese nation: SARS will soon disappear.

Now people are happy and are no longer troubled by SARS. However, when people were unprepared, the door of death was knocked open again-meningitis appeared. What is epidemic cerebrospinal meningitis? How to spread? How are the symptoms? A series of problems followed.

"Meningitis" is purulent meningitis caused by meningococcus. The "epidemic cerebrospinal meningitis" virus is hidden in the nasopharyngeal secretions of patients, and it spreads directly from the air through droplets such as coughing, sneezing and talking, and enters the respiratory tract to cause infection.

Once an infection is caused, if it is not rescued in time, the consequences will be unimaginable. The general symptoms are sudden high fever, severe headache, frequent vomiting, listlessness, stiff neck and even coma and convulsions.

"Meningitis" generally tends to children under 15 years old, and the illness is often divided into two types: ordinary type and explosive type, which often leads to death within 24 hours. Because of its high concealment, it is often mistaken for the common cold, which delays the diagnosis and treatment period and even endangers life.

We should conquer epidemic cerebrospinal meningitis with the great spirit of our nation. People often say that "everything has its vanquisher".

Encephalomyelitis is no exception. As long as preventive work is done, the "encephalomyelitis" virus will never visit our bodies again. The prevention of "epidemic cerebrospinal meningitis" is mainly to pay attention to ventilation, maintain personal hygiene, get more sunshine and eat reasonably.

I believe that as long as we remain vigilant, nip in the bud and unite as one, the sun will shine forever! Let health spread all over the country, let smiles hang on your cheeks, and let happiness last forever.

5. Write a news according to the Ebola epidemic. Hello! It can be written as follows:1May 1995 14 (the 15th day of the fourth lunar month), Ebola, a rare infectious disease, was discovered in Zaire.

Ebola is a general term used to refer to a group of viruses belonging to the family Fibroviridae, which can cause Ebola hemorrhagic fever. Suffering from this disease will lead to death, including several different degrees of symptoms, including nausea, vomiting, diarrhea, skin discoloration, general pain, internal bleeding, external bleeding, fever and so on. The symptoms of infected people are very similar to Marburg virus, which is also a family of fibroviruses. The virus is named after the Ebola River in the Democratic Republic of Congo (formerly Zaire) in Africa and is closely related to the tribes that broke out for the first time. Congo remains the site of four recent outbreaks, including the one in May 2005.

The biosafety level of Ebola virus is level 4 (AIDS is level 3, SARS is level 3, and the higher the level, the stricter the protection). The incubation period of the virus can reach 2 to 2 1 day, but usually it is only 5 to 10 day.

Among the viruses that broke out in Africa in 20 14, the worst Ebola outbreak on record has killed 932 people. Humans are infected with Ebola virus through close contact with the blood, secretions, organs or other body fluids of infected animals.

In Africa, people are infected through contact with chimpanzees, gorillas, fruit bats, monkeys, forest antelopes and porcupines in infected or dead rainforests. It is important to reduce contact with high-risk animals (fruit bats, monkeys or apes), including picking up dead animals found in the forest or handling their raw meat.

Once someone comes into contact with an animal infected with Ebola virus, it may cause interpersonal communication within the community. When people directly contact the blood, body fluids or other secretions (feces, urine, saliva and * * *) of infected people through damaged skin or mucosa, they can cause infection.

Infections can also occur when healthy people's damaged skin or mucous membranes come into contact with the environment or objects (such as dirty clothes, sheets or used needles) contaminated by Ebola patients' blood and body fluids. At the time of the outbreak, the people with high risk of infection were: (1) medical staff; (2) Family members or others who have close contact with patients; (3) Persons who have direct contact with the remains of the deceased during the funeral; (4) People who come into contact with the dead animals in the forest in the rainforest area.

More research is needed to know whether patients with immunodeficiency or other basic diseases are more susceptible to the virus than others. In clinics and hospitals, community gatherings or at home, you can take protective measures to reduce the chances of exposure to the virus.

Severe patients need intensive supportive treatment. Patients are often dehydrated and need intravenous or oral rehydration to replenish electrolytes.

There is no specific therapy at present. Some patients can recover after getting proper treatment.

Because there is no specific medicine for Ebola, the best treatment is to provide intensive support treatment for patients by hospital health workers under strict infection control procedures. According to the recommended protective measures, further infection can be controlled.

In order to control the further spread of the virus, suspected cases or confirmed cases should be isolated from other patients and treated by health workers who take strict infection protection measures. Whether Ebola virus can induce infected individuals to produce protective neutralizing antibodies is still controversial.

Prevention is mainly to isolate patients, thoroughly disinfect their secretions, excreta and used items, and medical staff should strictly implement protective measures. Due to natural selection, Ebola virus may appear new and more toxic variants, and may cause a global epidemic through aerosol transmission. Therefore, it is of great significance to determine the natural host of the virus as soon as possible, establish a rapid diagnosis method and develop a vaccine for the prevention and control of the disease.

Therefore, it is necessary to prevent diseases in time and never let such incidents happen again! Hope to adopt! ! .

6. Write a short essay of more than 600 words according to the drought in the south. Friendly reminder: Please don't copy short essays and hand in your homework.

You can learn from it and expect you to write a better composition.

In winter, we are all looking forward to the arrival of spring. Spring is the most beautiful picture in the world, when the snow and ice melt and birds are singing and flowers are fragrant. However, this spring. But this gave us a great shock:

There has been no rain in Guizhou and Yunnan for nine consecutive months, resulting in drought.

This year, Guizhou frequently stopped water supply. When you go shopping, you can see many people coming home with buckets. When there is water, they will use buckets to catch water. Now the drought is not just a matter of stopping water. The land in the countryside dried up and farmers were sunburned. As for the country, drought experts have been asked to bring drought-resistant agents to solve the problem.

In the past, we wasted water resources at will: we didn't turn off the tap and played with water. This year, this unusual spring made us realize the importance of WHO. In some places, water is continuously cut off, and the state also allocates funds for drilling wells and pumping machines. There is no water source in other places, so we have to send fire engines to pull water to replenish it. Everyone has only a dozen kilograms of water. Even if we save it, this water is not enough.

In this spring, it reminds us of the past, when there would be no water cut and no drought. Crops are growing well, vegetables are watery and grass is sprouting; Bloom; Birds are singing happily; We are playing on the grass. Everything is so calm and beautiful. But this year, a nightmare broke all this. The land is dry and cracked, the grass doesn't germinate and the flowers don't bloom, and our grassland has become a slope. The price of cheap vegetables has doubled, and we can't buy fresh vegetables anymore. If we had saved more water and planted more trees, we wouldn't have today's situation.

We will remember this extraordinary spring. It gives us a wake-up call and tells us that if we don't save water and plant more trees, this situation will continue into the future, the future and the future. .

7. Walking with the influenza 600-word proposition composition, the temperature is getting lower and lower, and the weather is getting colder and colder. The flu attacked our bodies unconsciously, making me depressed and unable to sleep well.

It is very interesting for us to play gyro time at school, but as long as one of us has the flu, everyone at the same table and around us will definitely be infected, and its infectivity is always unexpected. Maybe you will be infected by sneezing. It's a plague. Last Sunday, I was also infected with the flu. I feel dizzy when I wake up in the morning. I can't eat anything, but I throw up after eating.

My mother also felt that something was wrong with me, so she took out a thermometer and said to me, "Son, take your temperature yourself!" " "So I slowly put the thermometer in my mouth. After a long five-minute wait, when I looked at the thermometer in my mouth, her mother said, "Wow! Why did the temperature suddenly become 39? 5 C is so high! "My mother immediately helped me get dressed and said," Come on, son, I'm going to the hospital! " "So my parents and I came to Jiaxing Second People's Hospital against the cold wind. The doctor said, "Go for a blood test and then do a B-ultrasound!" " My mother went to the doctor with my blood test report and B-ultrasound list. The doctor said, "Go to the second floor to hang salt water!" " "My parents and I came to the preparation area, where there was already a sea of people.

I saw the shiny silver needle in my aunt's hand, and my legs were soft. The children's cries and screams echoed in my ears again and again. "Tang Zhouming" A doctor called my name, and I slowly moved to the chair and held out my hand very nervously.

The doctor said, "Hold your hands tight!" But I can't get up at this time. I slowly closed my eyes, but driven by curiosity, I opened my eyes again. I saw the needle go into my vein at lightning speed, and the pain followed. After a while, the pain gradually became numb, and I chatted with several patients.

At this moment, mom's cell phone rang. It turned out that our old classmate, Mr. Zhong, sent me a short message wishing me a speedy recovery. I must beat the flu and tell others this knowledge. Don't let the flu invade our bodies and be a healthy and happy me! O(∩_∩)O haha ~.
