There are three new characters(角色) in our daily life. I’m the main character COVID-19 vaccine(新冠疫苗), you are my partner nucleic acid test(核酸检测). We have an enemy. Its name is COVID-19(新型冠状病毒). Nowadays, COVID-19 is spreading around the world. It is very small but harmful, so people can't see it with their eyes. It can spread from one person to another easily and quickly. People are very afraid because it can make them sick and have a fever. That's why people stay at home and hide from it. Then I'm coming. I am COVID-19 vaccine. Everyone needs me because there is no special medicine to treat COVID-19. I can help people to stay away from the virus(病毒). People can get me for free in China. If they get me twice, they will have green health codes(健康码). Now people are supposed to get me a third time in the hospital. This can lower(降低) the risk of getting viruses. With the third vaccine, people's green health codes put on a shield(盾牌), and it's also a passport to enter public places. It is the best way to prevent COVID-19.
The nucleic acid test is my best partner. People just need to stand there and open their mouths to take it. Doctors and nurses are working so hard to check whether people have COVID-19 or not. They all think taking the nucleic acid test is the most useful way to find out who has got COVID-19. So far, the nucleic acid test and I have performed pretty well on this stage. Thanks to our strong country, we will pull together to make sure people can live a normal and safe life. |
