与新型冠状病毒有关的英语作文篇1
The novel coronavirus mobile phone is really serious. The first thing to do is to turn on the mobile phone and see the epidemic situation every morning. After reading, turn off the cell phone and lie down and go to sleep.
That said, everyone is at home now, and there is nothing to do without saying it. Because many people have online classes, the school is terrible. Now the winter vacation has been extended. Many people say on the Internet, is the school so cheap to earn? Worry about making up for the summer vacation.
Novel coronavirus, novel coronavirus, is written in second. The fact is that I found my last one, and scored well, so I came back to mix up. Ha ha ha ha ha, ha ha ha, and we return to the theme. According to the steps of normal speech, after a chat, we ask the question: what is a new coronavirus?
In fact, I don't want to say more here, just to clarify a few mistakes for you.
The first is the novel coronavirus, which is now suspected of being bats, not that the bat is confirmed, although most of the pieces are talking about bats, and even bat is not yet determined.
Second, all kinds of conspiracy theories are not impossible. They are just ridiculous, OK? If we don't talk about other things, we will talk about the problem of biological and chemical weapons attacking. If we don't talk about whether our technology can be achieved, let's talk about it. What's the advantage of using biological and chemical weapons to attack us? Improve your economy? Well, the economy has improved, but it also lacks a country that provides development for itself. This kind of thing that harms others and does not benefit oneself also benefits from the idea of those people who don't know who it is.
There are two misunderstandings, one is to refute rumors, the other is not officially determined, but these two are obviously contradictory. Eating bats is totally different from biological weapons. Eating bats is a natural disaster. It's death. Will there be so many things if you don't eat them? Chemical and biological weapons are man-made disasters. You can't avoid them. It's not that natural and man-made disasters can't coexist, but it's obviously not feasible in this matter.
Let's talk about how to protect ourselves in the face of this epidemic.
First, wear a mask. Ordinary masks are not good. We need medical surgical masks and N95 masks. But if there is no such mask, it is better to use ordinary masks.
Second, wash your hands frequently. In my last article, I used an exaggerated way to say "wash your hands after eating a mouthful of rice". Then someone came out and attacked me, so I'm sorry I'm wrong, but I dare to do it next time, because it's an exaggerated way to emphasize the importance of hand washing. To be honest, wash your hands before and after eating, and when you come back from the outside, wash your hands anyway.
Third, disinfection. Even if you don't have alcohol reserves at home, it's best if you have alcohol reserves. When you come back from the outside, you must be disinfected, no matter if you are not in a serious epidemic, especially your shoes. We all know the quality of our own people. If any infected person spits in the incubation period and you step on it unfortunately, it's a tragic story.
Fourth, don't take medicine indiscriminately. Before Shuanghuanglian oral liquid crazy robbery, I don't know how they think. What they say is inhibition. Only when you get it can you suppress it. Moreover, there is no clinical experiment. Secondly, if you are really unlucky, the state will help you cure it free of charge. Why do you spend this unjust money? And to be honest, there's an old saying in China called "three poisons of medicine". It's really damaging.
Well, in the end, I hope everyone is OK, and then I hope all the rebels can come back safely.
This is the end of my speech. Thank you.

One novel coronavirus named Black Swan came face to face, just like the legendary Pandora box, opened a 2020 door with a dark hand. The epidemic is rampant, the city is closed everywhere, the streets are cold and everyone can't go out.
So what is a novel coronavirus? It's so powerful. How does it enter the human body to make people sick? I have collected relevant scientific knowledge, combined with biology, to make an introduction.
A novel coronavirus, and influenza viruses we have often heard, are all viruses. By learning biology, we know that human cells can grow and divide into two cells. Virus is a kind of noncellular parasitic macromolecule. It has no cell that can divide itself. It is equivalent to the "parasite" of cell. It uses the raw materials in the infected cell to generate new virus. It does not accord with the characteristics that the living body can reproduce itself, but because it contains DNA, it has the ability of mutation and evolution.
Although it is impossible to determine the origin of the virus, it is believed that when life exists, the virus also exists. The name of the virus was given by Dutch microbiologist bjelink in 1899. However, people had no idea about the shape of the virus at that time. It was not until the invention of the electron microscope in 1931 that researchers first got pictures of the virus's morphology. After that, virus discovery entered the golden age, so far more than 5000 types of virus have been identified.
Viruses range in size from 20 to 300 nanometers (1 nanometre is 0.00000 1 mm) and their shapes vary widely. But the basic structure is the same, which is composed of DNA gene and protein shell.
It seems that viruses are really like "parasites". After so many years, they still depend on us. But after so long, they have not been able to defeat us, which means that we can always defeat them.
To this day, we are still in the trend of species evolution, in the battle after battle, the evolution of cells to make themselves stronger. Cells have been fighting against viruses for billions of years, and the winner is each of us.

Nowadays, the novel coronavirus is around us, which makes it impossible for us to go out. Do you know that there are many viruses around us? Some viruses have advantages and disadvantages.
Next to us, there are hundreds of millions of viruses in a square meter, and there are 10 million virus particles in a drop of water. How small is the virus? On average, 30000 viruses are equivalent to one bacterium, while 50000 bacteria are equivalent to one human liver cell. Scientists say about 800 million viruses fall from the sky every square meter every day. These viruses may enter the atmosphere with waves or sandstorms, and then fall to the ground.
Virus itself is a kind of non cellular life form. The virus also needs the host. When entering the host, the virus will start to copy its own genes and form new virus particles. These new virus particles will be released continuously and infect other healthy cells in the host body.
But to a certain extent, this has promoted the evolution of organisms. During the process of virus entering from one organism to another, it may take the DNA of one host, and these DNA may be accidentally infected by the virus in the body. As a result, the DNA of the infected person will appear a certain degree of variation. But when most mammals are pregnant, the mother's body will produce placenta, which is used to protect the embryo. Because the DNA of the embryo is different from that of the mother, the mother may have rejection reaction. The synthesis of placenta requires an endogenous retrovirus.
A few years ago, animals infected with the virus developed placenta for the first time, and this part of animals gradually evolved into mammals today. So the virus is not necessarily the enemy of human beings. The virus needs the host, not the survival of human beings. So there are many viruses that are not fatal, but when they enter the human body, because the immune system in the human body can not adapt to the arrival of the virus for the time being, they form a variety of diseases.
Virus is an essential organism on the earth, even in the center. We don't want to hear about the virus and believe in rumors. Everyone is well protected and disinfected. I believe we can take off our masks and go out soon.
